Pneumatic lifting rod has the advantages of high load, low noise, fast lifting, low shock resistance, strong self-falling buffer performance, stability, etc. The company's pneumatic lifting rod, pneumatic lifter, pneumatic lift, pneumatic lift platform, pneumatic lift bracket products are made of high-strength aluminum alloy, light weight, can meet different fields, the demand for height and load in different occasions plays an important role in various natural disasters, Emergency Events on-site night rescue and rescue. In addition, our products are also widely used in golf, night lighting of large football fields, etc.

 

Technical target
1 Collection height: customized according to customer requirements
2 Total height rise: customized according to customer requirements

 

I. from the pneumatic lifting rod/cylinder piston bearing gas pressure is one-way or two-way classification
(1) single-acting cylinder: the piston of the cylinder can only be pushed by air pressure in one direction, and external force is needed in the reverse direction.
(2) double-acting cylinder: the piston of the cylinder is pushed by air pressure in both positive and negative directions.

 

II. Classification from the installation form of pneumatic lifting rod/cylinder
(1) fixed cylinder: the cylinder body of the cylinder cannot be fixed.
(2) axle pin type cylinder: the cylinder body of the cylinder can swing around the fixed axle pin in a certain angle.
(3) rotary cylinder: the cylinder body is usually fixed on the main shaft of the machine tool and can rotate together with the main shaft of the machine tool randomly. This kind of cylinder is often used for pneumatic Chuck on the machine tool.

 

III. from the function and use of pneumatic lifting rod/cylinder classification
(1) ordinary cylinder: including single-acting and double-acting cylinders. This type of cylinder is generally used without special requirements.
(2) buffer cylinder: the cylinder is equipped with buffer device, which can avoid strong impact when the piston moves to the end. This kind of cylinder is often used in working occasions with high pressure and high movement speed.
(3) gas-liquid damping cylinder: the cylinder is connected in series with the hydraulic cylinder, which can obtain a relatively accurate movement speed. This kind of cylinder can be used in occasions with high requirements for speed regulation.
(4) swing cylinder: the movement of the cylinder is used as reciprocating rotation around the axis, which can be used for fixture transposition, valve switch, etc.
(5) impact cylinder: it is a kind of high-energy cylinder with high-speed movement of piston rod to form impact force, which can be used for stamping, cutting, etc.

Hydraulic lifting platform is a kind of multifunctional lifting and loading machinery equipment. Hydraulic lifting platform is divided into: four-wheel mobile lifting platform, two-wheel traction lifting platform, car modified lifting platform, hand-propelled lifting platform, hand-propelled lifting platform, AC/DC dual-use lifting platform, battery vehicle-mounted lifting platform, the lifting height ranges from 1 meter to 30 meters.

 

Hydraulic principle of lifting platform
Hydraulic oil forms a certain pressure by vane pump, and enters the lower end of the liquid cylinder through oil filter, flameproof electromagnetic reversing valve, throttle valve, hydraulic control one-way valve and balance valve, making the piston of the liquid cylinder move upward and lifting heavy objects, the oil return at the upper end of the liquid cylinder is returned to the oil tank through the flameproof 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 liquid cylinder moves downward (the weight drops). The hydraulic oil enters the upper end of the liquid cylinder through the explosion-proof electromagnetic reversing valve, and the oil return at the lower end of the liquid cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve and explosion-proof electromagnetic reversing valve. In order to make the weight drop steadily and the braking is safe and reliable, a balance valve is set on the oil return Road to balance the loop and maintain the pressure so that the falling speed is not changed by the weight. Throttle valve is used to adjust the flow rate and control the falling speed. In order to ensure the safety and reliability of braking and prevent accidents, hydraulic control check valve, namely hydraulic lock, is added to ensure the safe self-locking when the hydraulic pipeline burst unexpectedly. Overload sound control alarm is installed to distinguish overload or equipment failure.
The electrical control system controls the rotation of the motor and the reversing of the explosion-proof electromagnetic reversing valve through the SB1-SB6 of the explosion-proof button to keep the load rising or falling, and adjusts the time delay through the "LOGO" program, avoid frequent starting of the motor and affect the service life.
