Pneumatic cylinder valve loading and unloading machine

Abstract

The invention mainly discloses a pneumatic cylinder valve loading and unloading machine which comprises a conveying rack, a gas cylinder clamping device, a cylinder valve loading and uploading device, a fixture positioning device and a gas circuit system; wherein the gas cylinder clamping device is arranged above the conveying rack, the gas cylinder enters the conveying rack to be manually adjusted to ensure that the gas cylinder aims at the cylinder valve loading and unloading device which is arranged on the fixture positioning device, and then the gas cylinder is clamped by the gas cylinder clamping device, and the gas cylinder is loaded or unloaded by the cylinder valve loading and unloading device; the gas cylinder clamping device and the cylinder valve loading and unloading device are under pneumatic control of the gas circuit system. The pneumatic cylinder valve loading and unloading machine adopts gas-source drive, is safe and reliable and has long service life; furthermore, the position of the fixture in the longitudinal and transverse directions can be adjusted, the fixture is convenient to position and can apply to gas cylinders with various specifications in size, the size of the rated output torque can be adjusted, the control accuracy of the torque is high, the output torque can be increased when the valve is difficult to load and unload, so that the pneumatic cylinder valve loading and unloading machine has a wider range of application.

Description

technical field [0001] The invention relates to the technical field of bottle valve loading and unloading equipment, in particular to a pneumatic bottle valve loading and unloading machine. Background technique [0002] Gas cylinders are pressure vessels used for compressed gas transportation. The quality of gas cylinders is directly related to people's personal and property safety. Therefore, relevant inspections must be carried out before leaving the factory and after a certain number of years of use. The cylinder valve on the gas cylinder needs to be unloaded or installed during the detection process. Therefore, cylinder valve loading and unloading is an important part of the production and inspection process of gas cylinders. [0003] In the prior art, the bottle valve loading and unloading machines used in gas cylinder production inspection and related industries have the following deficiencies: 1.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the bottle valve loading and unloading machines used in gas cylinder production inspection and related industries have the following deficiencies: 1. The bottle valve loading and unloading machines in the current technology are generally provided with a bottle valve loading and unloading machine driven by a geared motor on the top of the frame. Because the height of the reducer is fixed, the range of cylinder height applicable to this type of bottle valve loading and unloading machine is narrow, and because the output torque of the reducer is generally fixed and the torque is relatively large, it cannot be output according to the specifications of the cylinder valve. Torque, when assembling small-sized gas cylinder valves, the larger output torque is easy to damage the cylinder valve

2. Most of the bottle valve loading and unloading machines in the current technology are driven by electricity. The motor drives the clamping equipment to rotate to complete the operation of loading and unloading the valve. When the electric equipment is turned on or stopped, the current is easily overloaded, resulting in excessive torque peak value during the valve loading process. High, damage the valve, and at the same time accelerate the damage process of the coil or motor and other equipment, and even directly cause the equipment to burn out, affecting the service life of the bottle valve loading and unloading machine

Moreover, the valve equipment installed in the gas cylinder production and inspection line is used after the gas cylinder hydrostatic test, and the operator may carry water to operate the equipment, which is likely to cause safety hazards

3. Due to reasons such as rust or chemical corrosion, the valves of used gas cylinders are prone to solidification. The cylinder valve loading and unloading machine in the current technology cannot increase the output torque during the valve unloading process, and it is easy to stop, which affects both production efficiency and It is easy to cause problems such as current overload
