Description

Technical Field

[0001] The utility model relates to the technical field of buffer devices, in particular to a bidirectional buffer device of an aggregate spring. Background Art

[0002] The spring buffer is an energy storage buffer that converts the kinetic energy of the car or counterweight into the elastic potential energy of the spring, thereby playing a buffering role.

[0003] Existing technologies all rely solely on the mechanical movement of springs to achieve buffering, which is very likely to cause strain problems under long-term repeated operation. Therefore, a bidirectional buffering device with a spring is proposed, which achieves a double buffering effect through hydraulic buffering and springs to reduce the strain of a single buffering method and improve the buffering effect. Utility Model Content

[0004] In response to the problems in the prior art, the utility model provides a bidirectional buffer device with a spring assembly, which achieves a double buffering effect through a hydraulic buffering method in conjunction with a spring, so as to reduce the wear of a single buffering method and improve the buffering effect.

[0005] The technical solution adopted by the utility model to solve the technical problem is a bidirectional buffer device with a spring assembly, comprising a lower lifting ring, a buffer spring, an upper cover body, an upper cover end face sealing plate and an upper lifting ear, wherein the top outer cover of the lower lifting ring is provided with an oil storage cylinder locking cap, and a piston rod is sleeved through the top inner side of the oil storage cylinder locking cap;

[0006] The top of the inner cavity of the piston rod is filled with air, a buffer rod is provided on the inner side of the piston rod corresponding to the bottom of the air, and the outer periphery of the buffer rod is filled with hydraulic oil in the locking cap of the oil storage cylinder corresponding to the oil storage cylinder.

[0007] By adopting the above technical solution, when the buffer is in motion, the device is in a free and compressed state, and the buffer spring plays a major role. When compressed to the limit state, the buffer spring will convert elastic potential energy into kinetic potential energy due to its elasticity, and the device will move upward, and the whole device will become longer. In addition, the outer surface of the buffer spring is covered with an anti-wear sleeve, and the anti-wear sleeve is made of rubber material to avoid direct contact and friction between the buffer springs when contracting, which may cause wear and other problems under long-term action.

[0008] There are sealing rings between the buffer rod and the piston rod, and between the oil storage cylinder locking cap and the piston rod to prevent air and hydraulic oil leakage;

[0009] When the piston rod moves downward, the air in the piston rod cavity begins to compress. At the same time, because the hydraulic oil is incompressible, the buffer rod will be squeezed by the hydraulic oil and move upward, further slowing down the downward movement of the piston rod, thereby playing a buffering role and assisting the buffer spring to complete the buffering effect, thereby reducing the wear of a single buffering method and improving the buffering effect;

[0010] When the device rebounds, due to the upward movement of the piston rod, the air space between the piston rod and the buffer rod will become larger, and the buffer rod will move downward. Because of the presence of hydraulic oil, this process will be slowed down, thereby achieving a buffering effect.

[0011] Specifically, the upper lifting lug is arranged at the top end of the upper cover end surface sealing plate.

[0012] By adopting the above technical solution, the upper lifting lug is utilized to facilitate hooking on the component.

[0013] Specifically, the upper cover end surface sealing plate passes through the top of the upper cover body through a reserved opening.

[0014] By adopting the above technical solution, the upper cover body is used to clamp the upper cover end surface sealing plate.

[0015] Specifically, a buffer spring is provided at the bottom of the upper cover end face sealing plate corresponding to between the upper cover body and the lower hanging ring, and an anti-wear sleeve is provided on the outer surface of the buffer spring, and the anti-wear sleeve is made of rubber material.

[0016] By adopting the above technical solution and using the anti-wear sleeve as rubber material, the buffer springs are prevented from directly contacting and rubbing with each other during contraction, thereby preventing problems such as wear and tear caused by long-term action.

[0017] Specifically, a seal is provided between the buffer rod and the piston rod, and a seal is adhered to the contact position between the inner wall of the oil storage cylinder locking cap and the lower lifting ring.

[0018] By adopting the above technical solution, sealing rings are provided between the buffer rod and the piston rod, and between the oil storage cylinder locking cap and the piston rod to prevent leakage of air and hydraulic oil.

[0019] Beneficial effects of the utility model:

[0020] (1) In the bidirectional buffer device of the collective spring described in the utility model, when the piston rod moves downward, the air in the piston rod cavity begins to compress. At the same time, because the hydraulic oil cannot be compressed, the buffer rod will be squeezed by the hydraulic oil to move upward, further slowing down the downward movement of the piston rod, thereby playing a buffering role, assisting the buffer spring to jointly complete the buffering effect, thereby reducing the wear of a single buffering method and improving the buffering effect.

[0021] (2) The bidirectional buffer device of the collective spring described in the utility model is provided with an anti-wear sleeve on the outer surface of the buffer spring, and the anti-wear sleeve is made of rubber material to avoid direct contact and friction between the buffer springs when they contract, thereby preventing problems such as wear and tear caused by long-term action.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] In order to reduce the wear of a single buffering method and improve the buffering effect, such as Figure 1-3 As shown, the bidirectional buffer device of the integrated spring of the utility model includes a lower lifting ring 1, a buffer spring 5, an upper cover body 6, an upper cover end surface sealing plate 7 and an upper lifting ear 8. The top outer cover of the lower lifting ring 1 is provided with an oil storage cylinder locking cap 2, and the top of the inner side of the oil storage cylinder locking cap 2 is penetrated and sleeved with a piston rod 3;

[0029] The top of the inner cavity of the piston rod 3 is filled with air 9, and a buffer rod 4 is provided on the inner side of the piston rod 3 corresponding to the bottom of the air 9. The outer periphery of the buffer rod 4 is filled with hydraulic oil 10 corresponding to the oil storage cylinder locking cap 2.

[0030] When in use, the buffer is in motion, the device is in a free and compressed state, and the buffer spring 5 plays a major role. When compressed to the limit state, the buffer spring 5 will convert the elastic potential energy into kinetic potential energy due to its elasticity, and the device will move upward, and the whole device will become longer. The outer surface of the buffer spring 5 is covered with an anti-wear sleeve 11, and the anti-wear sleeve 11 is made of rubber material to avoid direct contact and friction between the buffer springs 5 ​​when contracting, which may cause wear and other problems under long-term action;

[0031] There are sealing rings between the buffer rod 4 and the piston rod 3, and between the oil storage cylinder locking cap 2 and the piston rod 3 to prevent leakage of air 9 and hydraulic oil 10;

[0032] When the piston rod 3 moves downward, the air in the piston rod 3 cavity begins to compress. At the same time, because the hydraulic oil is incompressible, the buffer rod 4 will be squeezed by the hydraulic oil to move upward, further slowing down the downward movement of the piston rod 2, thereby playing a buffering role, and assisting the buffer spring 5 to complete the buffering effect, thereby reducing the wear of a single buffering method and improving the buffering effect;

[0033] When the device rebounds, due to the upward movement of the piston rod 3, the air space between the piston rod 3 and the buffer rod 4 will become larger, and the buffer rod 4 will move downward. Because of the presence of hydraulic oil, this process will be slowed down, thereby achieving a buffering effect.

[0034] In order to reduce the wear of a single buffering method and improve the buffering effect, for example, Figure 1 、 Figure 3 As shown, the present invention further includes that the upper lifting lug 8 is arranged on the top end of the upper cover end surface sealing plate 7.

[0035] When in use, the upper hanging ear 8 is used to facilitate hooking on the component.

[0036] For example, Figure 1 、 Figure 3 As shown, the present invention further includes that the upper cover end surface sealing plate 7 passes through the top of the upper cover body 6 through a reserved opening.

[0037] When in use, the upper cover end surface sealing plate 7 is clamped and covered by the upper cover body 6 .

[0038] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the utility model also includes a buffer spring 5 provided between the upper cover body 6 and the lower hanging ring 1 at the bottom of the upper cover end face sealing plate 7, and an anti-wear sleeve 11 is provided on the outer surface of the buffer spring 5, and the anti-wear sleeve 11 is made of rubber material.

[0039] During use, the anti-wear sleeve 11 is made of rubber material to prevent the buffer springs 5 ​​from directly contacting and rubbing against each other when contracting, thereby preventing problems such as wear and tear caused by long-term action.

[0040] For example, Figure 1 、 Figure 2 、 Figure 3 As shown, the present invention further includes a seal provided between the buffer rod 4 and the piston rod 3 , and a seal adhered to the contact position between the inner wall of the oil storage cylinder locking cap 2 and the lower lifting ring 1 .

[0041] When in use, there are sealing rings between the buffer rod 4 and the piston rod 3, and between the oil storage cylinder locking cap 2 and the piston rod 3 to prevent leakage of air 9 and hydraulic oil 10.

[0042] When the utility model is in use, the buffer is in motion, the device is in a free and compressed state, and the buffer spring 5 plays a major role. When compressed to the limit state, the buffer spring 5 converts elastic potential energy into kinetic potential energy due to its elasticity, and the device moves upward, and the whole becomes longer. The outer surface of the buffer spring 5 is covered with an anti-wear sleeve 11, and the anti-wear sleeve 11 is made of rubber material to avoid direct contact and friction between the buffer springs 5 ​​when contracting, which may cause wear and other problems under long-term action;

[0043] There are sealing rings between the buffer rod 4 and the piston rod 3, and between the oil storage cylinder locking cap 2 and the piston rod 3 to prevent leakage of air 9 and hydraulic oil 10;

[0044] When the piston rod 3 moves downward, the air in the piston rod 3 cavity begins to compress. At the same time, because the hydraulic oil is incompressible, the buffer rod 4 will be squeezed by the hydraulic oil to move upward, further slowing down the downward movement of the piston rod 2, thereby playing a buffering role, and assisting the buffer spring 5 to complete the buffering effect, thereby reducing the wear of a single buffering method and improving the buffering effect;

[0045] When the device rebounds, due to the upward movement of the piston rod 3, the air space between the piston rod 3 and the buffer rod 4 will become larger, and the buffer rod 4 will move downward. Because of the presence of hydraulic oil, this process will be slowed down, thereby achieving a buffering effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
