Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] Such as figure 1 As shown, a special gas spring device for mining is mainly composed of a load-bearing device 1, a spring rod 2, a spiral gas spring 3, a gasket 4, a valve core 5, an air compressor 6, and a sealing valve 7.

[0017] Such as figure 1 As shown, the helical gas spring 3 is a helical high-pressure rubber tube made of rubber material, and the helical gas spring 3 is coiled on the spring rod 2 .

[0018] Such as figure 1 As shown, a sealing valve 7 is installed on the top of the helical gas spring 3, and a valve core 5 is installed on the end of the helical gas spring 3.

[0019] Such as figure 1 As shown, the air compressor 6 is connected with the valve core 7, and through the valve core 7, the air compressor 6 rushes into the spiral gas spring 3 with high-pressure air.

[0020] Such as figure 1 As shown, the load-bearing device 1 and the spri...

Abstract

The invention discloses an air spring device special for mineral product exploitation. The air spring device is mainly composed of a bearing device, a spring rod, a spiral air spring, a gasket, a valve core, an air compressor and a sealing valve. The spiral air spring is a spiral high-pressure rubber pipe made of rubber materials, and the spiral air spring is spiraled on the spring rod. The sealing valve is installed at the top end of the spiral air spring, and the valve core is installed at the tail end of the spiral air spring. The air compressor is connected with the valve core, and the air compressor inflates the spiral air spring with high-pressure air through the valve core. According to the air spring device special for mineral product exploitation, the method of inflating the spiral air spring with the high-pressure air is adopted for achieving the function of an original air spring, and a quite good effect is achieved. The air spring device is simple and unique in structural design, simple in use and operation method, low in manufacturing cost, easy to repair and maintain and wide in market prospect and popularization value.

Description

technical field [0001] The invention relates to an elastic device formed by an air compression system, in particular to a gas spring device specially used for mining. Background technique [0002] The gas spring device has a good buffering and vibration reduction effect, and the gas spring is small in size and low in cost, and is widely used in various fields. The working principle of the gas spring is to fill the closed pressure cylinder with inert gas or oil-gas mixture, so that the pressure in the cavity is several times or dozens of times higher than the atmospheric pressure, and the cross-sectional area of ​​the piston rod is smaller than that of the piston. The resulting pressure difference is used to move the piston rod. Chinese Patent No. CN2687418Y discloses a gas spring, which is mainly composed of a cylinder liner, a piston, a piston rod, a guide sleeve, and a tail seal. A packing groove is processed near one end of the piston rod, and a blind hole is formed on ...
