Working principle of hydraulic Cargo lift, structure of hydraulic lift platform

In the modern industrial society, the appearance of mechanical products plays a very important role for us to speed up the progress of the project, and provides the most convenient form of operation. The appearance of the elevator solves the influence of gravity on the construction very well, and can ignore the influence of gravity. rapid rise and fall, where

The hydraulic lift is the most common type of lift at present. Its working principle basically meets the requirements of the lift, but it is safer and easier to operate. At present, its application is very extensive, and there are many types of hydraulic lifting platforms. Each type The hydraulic lift platform is also to adapt to different construction conditions,

Next, جينان TE موجة رفع البضائع المجموعة المحدودة will introduce to you the relevant knowledge of hydraulic lifts and understand how their working principles are.

How hydraulic Cargo lifts work

Hydraulic elevator is a kind of elevator equipment composed of walking mechanism, hydraulic mechanism, electric control mechanism and support mechanism.

The hydraulic oil is formed by the vane pump to a certain pressure, and enters the lower end of the hydraulic cylinder through the oil filter, explosion-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve and balance valve, so that the piston hydraulic cylinder of the piston moves upward and lifts. heavy objects.

The oil returned from the upper end of the liquid cylinder is returned to the oil tank through the explosion-proof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure measurement.

Hydraulic lift is composed of oil tank, hydraulic oil gear pump, one-way valve, solenoid valve and hydraulic cylinder.

Start the hydraulic oil gear pump to continuously pressurize the hydraulic oil in the tank to the hydraulic cylinder along the pipeline pump, and the plunger in the hydraulic cylinder (connected to the bed surface) rises. In the way of ascending; when descending, just turn on the solenoid valve to open the return circuit, the oil returns to the oil tank, the hydraulic cylinder is decompressed, and the plunger descends.

 

The pressure oil is formed by the vane pump to a certain pressure, and enters the lower end of the liquid cylinder through the oil filter, the flameproof electromagnetic reversing valve, the throttle valve, the hydraulic control check valve and the balance valve, so that the piston of the liquid cylinder moves upward and lifts the weight. The oil returned from the upper end of the liquid cylinder is returned to the fuel tank through the explosion-proof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge.

The piston of the hydraulic cylinder moves downward (ie, the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve, and the return oil at the lower end of the hydraulic cylinder returns to the fuel tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects descend smoothly and the braking is safe and reliable, a balance valve is set on the oil return road to balance the circuit and maintain the pressure, so that the descending speed is not changed by the heavy objects, and the flow rate is adjusted by the throttle valve to control the lifting speed.

In order to make the braking safe and reliable and prevent accidents, a hydraulic control one-way valve, namely a hydraulic lock, is added to ensure safe self-locking when the hydraulic pipeline bursts unexpectedly. An overload sound alarm is installed to distinguish overload or equipment failure.

The hydraulic lifting platform mainly realizes the lifting function through the pressure transmission of hydraulic oil. Its scissor fork mechanical structure makes the lifting of the lift have high stability, wide working platform and high bearing capacity, making the working range at high altitude Larger and suitable for multiple people to work at the same time. It makes aerial work more efficient and safer.

Classification of hydraulic lifts

Hydraulic lifts can be divided into several types according to their types. Each type of hydraulic lifts will operate in different ways and have different product characteristics. The following is a brief introduction to several types of hydraulic lifts. .

Four-wheel mobile lift of hydraulic lift

For manual movement, there are four wheels for movement, which is simple and stable. The lowering power of the platform is two-phase, three-phase or DC 24V, 36V power supply. It can also be changed to some oil generators as power. The control methods include manual control and electric control. In addition, hand pressure pump and manual lowering device are provided. can still be used normally. It has the characteristics of flexible movement, stable lifting, large carrying capacity and convenient operation. It is mainly used in factories, airports, offices, shops, stations and building decoration industries.

The lift is stable and the operation is easy. Flexible operation and safe use. Pure manual operation. Mainly used in factories, airports, institutions, shops, stations and building decoration and other industries.

Two-wheel traction lift of hydraulic lift

The two-wheel traction lift is a scissor-type structure. The lifting platform has high stability, wide working platform and high bearing capacity, which makes the aerial work range larger and is suitable for multiple people to work at the same time. It makes aerial work more efficient and safer.

The two-wheeled traction lift is easy to move, suitable for various rugged terrains in the field, and has a wide range of space operations. It is mainly used for construction, bridge construction, shipbuilding, airports, mines, port terminals, communication and power facilities construction and outdoor advertising projects. Equipment.

Hydraulic lift car modification lift table

The automobile modified lift table is a kind of mechanical equipment with wide application prospects. It is a special equipment for high-altitude operation and transportation modified on the second-class chassis, with hydraulic components as the power components and support rods as the main bearing components.

The car modified lift table can be used for high-altitude operations and maintenance in factories, automatic warehouses, parking lots, municipalities, docks, construction, decoration, logistics, electricity, transportation, petroleum, chemical industry, hotels, gymnasiums, industrial and mining, enterprises, etc. The lifting system of the lifting platform is driven by hydraulic pressure, also known as the hydraulic lifting platform, so the development prospect is very good.

Structure of hydraulic cargo lift

1. Hydraulic Cargo Lift base, each lifting platform has a chassis made of a welded frame, and the five supporting feet on the chassis are used to disperse the pressure of the load from the column.

2. Column, the column is a triangular structure welded by steel pipes, chain gears, steel bars, etc. The columns are divided into standard and limit columns. The limit columns are most at the top and bottom, and the bottom is to switch the limit of the limit column. Automatically stop when driving down to prevent the drive from hitting the base or unexpectedly dangerous things.

3. Hydraulic Cargo Lift beam, the beam of the lifting platform is the basis for the overall work of the lifting platform. It is a triangular structure frame welded with three high-quality steels, which is sturdy and reliable to ensure the safety of the entire work.

4. The drive, the lifting platform is installed with the drive device to control the certain guide wheels on the column well, and the drive motor has a self-braking device, which can stop the drive motor from moving on the rack on the column in the event of a power failure.

5. Safety protection parts, in order to work safely, it is essential to install the lifting platform for protection. The main protection accessories are safety guards, guardrails, protective covers, platform stairs, etc.
