[0002] Coke oven gas compression refers to the compression of coke oven gas during the coking production process to improve its compression ratio and combustion efficiency while reducing environmental pollution. This compression is usually achieved by centrifugal compression and exhaust compression.

[0003] At present, during the use of coke oven gas compressors, in order to improve their anti-vibration performance, a shock-absorbing base is usually added to the compressor base. However, the existing shock-absorbing mechanism has a single functionality and can only achieve the purpose of single-direction support and buffering. Faced with the amplitude generated in different directions, the pressure generated by the vibration will still directly act on the compressor, making its shock-absorbing effect less than ideal. Utility Model Content

Faced with amplitudes generated in different directions, the pressure generated by the vibration will still directly act on the compressor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coke oven gas compressor shock absorbing device, comprising a support seat, a support plate is installed on the support seat, a deflection assembly is provided through the middle of the support plate, the deflection assembly comprises a piston cylinder, a piston rod is sleeved in the piston cylinder, a ball is fixed to the bottom end of the piston cylinder, a ball groove is opened at the bottom of the support seat, the ball is sleeved in the ball groove, and a spring is sleeved on the outer surface of the piston rod;

[0006] The bottom end of the spring 1 is fixed to the top of the piston cylinder, the top end of the piston rod is fixedly connected to a mounting seat, an expansion extrusion component is overlapped on the outside of the piston rod, the bottom of the expansion extrusion component is connected to the piston cylinder, a plurality of support components are overlapped on the bottom of the mounting seat, and the bottom of the support component is installed on a support plate.

[0007] As a further solution of the utility model: a plurality of mounting holes are provided at the bottom of the mounting seat, and a plurality of blocking pieces are provided at the edge of the mounting seat.

[0008] As a further solution of the utility model: the expansion extrusion assembly includes a ferrule, the ferrule is clamped in the middle of the support plate, an air cushion is arranged in the ferrule, and the inner wall of the air cushion overlaps the outer wall of the piston rod.

[0009] As a further solution of the utility model: the air cushion ring is externally connected to four air guide tubes, and the ends of the four air guide tubes pass through the ferrule and are connected to the piston cylinder.

[0010] As a further solution of the utility model: the support assembly includes a connecting plate, the bottom of the connecting plate is connected to a pin shaft, and the connecting plate is hinged to the support plate through the pin shaft.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The coke oven gas compressor shock absorbing device installs the coke oven gas compressor by setting a mounting seat. When the coke oven gas compressor is working, it will vibrate and squeeze the piston rod. The piston rod will slide in the piston cylinder, and the elastic force of the spring 1 will support and buffer the piston rod, so that the mounting seat and the coke oven gas compressor can shake slightly in the vertical direction. When facing the amplitude generated in different directions, the piston cylinder can drive the ball to deflect in the ball groove, and cooperate with multiple support components to support the bottom of the mounting seat. Because the ball can deflect at multiple angles in the ball groove, the purpose of multi-directional shock absorption protection of the coke oven gas compressor is achieved.

[0014] 2. The shock absorbing device of the coke oven gas compressor squeezes the piston rod through the mounting seat, so that the gas inside the piston cylinder can be introduced into the air cushion ring through the air guide pipe. When the air cushion ring expands, it is close to the piston rod, which plays a role of buffering and damping the piston rod, and prevents the mounting seat and the coke oven gas compressor from high-frequency shaking affecting the working stability. When the mounting seat squeezes the rolling body on the support assembly, the rolling body can roll and cooperate with the spring two pairs of connecting plates to provide reverse support, which plays a role of supporting and protecting the mounting seat and the coke oven gas compressor, and ensures the working stability of the coke oven gas compressor.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a shock absorbing device for a coke oven gas compressor, comprising a support seat 1, a support plate 2 is mounted on the support seat 1, a deflection assembly 3 is provided through the middle of the support plate 2, the deflection assembly 3 comprises a piston cylinder 301, a piston rod 303 is sleeved in the piston cylinder 301, a ball 302 is fixed to the bottom end of the piston cylinder 301, a ball groove 6 is provided at the bottom of the support seat 1, the ball 302 is sleeved in the ball groove 6, a spring 304 is connected to the outer sleeve of the piston rod 303, and because the spring 304 is provided, the elastic force of the spring 304 supports and buffers the piston rod 303, so that the mounting seat 4 and the coke oven gas compressor can be slightly shaken in the vertical direction;

[0022] The bottom end of the spring 1 304 is fixed to the top of the piston cylinder 301, and the top end of the piston rod 303 is fixedly connected to the mounting seat 4. The bottom of the mounting seat 4 is provided with a plurality of mounting holes 8, and the edge of the mounting seat 4 is provided with a plurality of baffles.

[0023] The piston rod 303 is overlapped with an expansion and extrusion component 5, which includes a ferrule 501, which is clamped in the middle of the support plate 2, and an air cushion 502 is arranged in the ferrule 501, and the inner wall of the air cushion 502 overlaps the outer wall of the piston rod 303. Due to the provision of the air cushion 502, the air cushion 502 expands and is closely attached to the piston rod 303, which plays a role in buffering and damping the piston rod 303, thereby preventing the high-frequency shaking of the coke oven gas compressor from affecting the working stability;

[0024] The air cushion ring 502 is externally connected to four air guide tubes 503 , the ends of the four air guide tubes 503 pass through the ferrule 501 and are connected to the piston cylinder 301 . Because of the provision of the air guide tubes 503 , the air guide tubes 503 allow the gas in the piston cylinder 301 to circulate between the air in the air cushion ring 502 , and the expansion pressure of the air cushion ring 502 can be adaptively adjusted.

[0025] The bottom of the expansion and extrusion assembly 5 is connected to the piston cylinder 301. The bottom of the mounting seat 4 is overlapped with a plurality of support assemblies 7. The bottom of the support assembly 7 is mounted on the support plate 2. The support assembly 7 includes a connecting plate 701. The bottom of the connecting plate 701 is connected to a pin shaft 702. The connecting plate 701 is hinged to the support plate 2 through the pin shaft 702. Due to the provision of the pin shaft 702, the connecting plate 701 can be deflected, so that the mounting seat 4 can float up and down normally to protect the compressor.

[0026] A rolling body 703 is provided on the top of the connecting plate 701, and the rolling body 703 overlaps with the bottom of the mounting seat 4. A spring 2 704 is fixedly connected between the connecting plate 701 and the support plate 2.

[0028] When in use, the coke oven gas compressor is installed in the mounting seat 4. The coke oven gas compressor will vibrate and squeeze the piston rod 303 when working. The piston rod 303 is supported by the elastic force of the spring 1 304, so that the mounting seat 4 and the coke oven gas compressor can shake slightly in the vertical direction. When facing the amplitude generated in different directions, the piston cylinder 301 can drive the ball 302 to deflect in the ball groove 6, and cooperate with multiple support components 7 to support the bottom of the mounting seat 4, so as to achieve the purpose of multi-directional shock absorption protection of the coke oven gas compressor, and the gas inside the piston cylinder 301 can be introduced into the air cushion 502 through the air guide pipe 503. The air cushion 502 expands and fits the piston rod 303, which plays a role of buffering and damping the piston rod 303. When the mounting seat 4 squeezes the rolling body 703 on the support component 7, the rolling body 703 can roll, and cooperate with the spring 2 704 to reversely support the connecting plate 701, which plays a role of supporting and protecting the mounting seat 4 and the coke oven gas compressor.
