Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to an anti-seismic structure for a high-power vehicle-mounted gas engine set. Background Technique

[0002] Gas generator sets are new types of generator sets developed to meet the world's environmental protection requirements and the new market environment. Natural gas generator sets are mainly divided into two types, one is a combined cycle gas turbine, and the other is a gas internal combustion engine. Gas turbines have relatively large power and are mainly used in large and medium-sized power stations. Gas internal combustion engines have relatively small power and are mainly used in small distributed power stations. It is a new type of green and environment-friendly power that replaces fuel and coal-fired units.

[0003] However, there are still deficiencies in the use of related high-power vehicle-mounted gas engine sets. Since the vehicle-mounted gas engine set will generate relatively large vibrations during operation, especially for high-power vehicle-mounted gas engine sets, the greater the power, the greater the vibration amplitude. Under relatively large vibrations, it is not only easy to affect the stability of the operation of the engine set, but also easy to damage the components inside the engine set, reducing the service life of the engine set. Therefore, we propose an anti-seismic structure for a high-power vehicle-mounted gas engine set to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned disadvantages and propose an anti-seismic structure for a high-power vehicle-mounted gas engine set.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An anti-seismic structure for a high-power vehicle-mounted gas engine set, including a high-power vehicle-mounted gas engine set body, and a fixed seat and a mounting seat for anti-seismic use of the high-power vehicle-mounted gas engine set body. Four grooves and four chutes are provided at the top of the mounting seat. A first anti-seismic unit is arranged between the groove, the mounting seat and the fixed seat, and a second anti-seismic unit is arranged between the chute and the fixed seat. The mounting seat and the fixed seat are fixedly connected with the same shock-absorbing steel plate. Two ear plates are fixedly connected to both sides of the high-power vehicle-mounted gas engine set body. A screw rod is threadedly connected to the top of the ear plate, and the ear plate is fixedly connected to the top of the fixed seat through the screw rod.

[0007] Specifically, the first anti-seismic unit includes a spring one fixedly connected to the inner wall of one side of the groove and a damper one fixedly connected to the top of the mounting seat. One end of the damper one and the spring one are fixedly connected with the same slider. A connecting rod is rotatably connected to the front side of the slider, and the top end of the connecting rod is rotatably connected to the bottom of the fixed seat.

[0008] Specifically, four connecting plates are fixedly connected to the bottom of the fixed seat, and the four connecting rods are respectively rotatably connected to the front sides of the corresponding connecting plates.

[0009] Specifically, the slider is slidably sleeved in the groove.

[0010] Specifically, the second anti-seismic unit includes two second springs. One end of each of the two second springs, which are away from each other, is fixedly connected to the inner walls on both sides of the chute. One end of the two second springs, which are close to each other, is fixedly connected to the same moving seat. A third spring and a second damper are fixedly connected to the top of the moving seat. The tops of the third spring and the second damper are both fixedly connected to the bottom of the fixed seat.

[0011] Specifically, a rubber damping pad is fixedly sleeved on the outside of the moving seat, and the rubber damping pad is slidably and dampingly sleeved in the chute.

[0012] Specifically, damping rings are fixedly connected to both sides of the moving seat. The same guide rod is fixedly connected to the inner walls on both sides of the chute. Both damping rings are slidably and dampingly sleeved on the outside of the guide rod, and both of the two second springs are sleeved on the outside of the guide rod.

[0013] Specifically, a shielding cloth is fixedly sleeved on the outside of the fixed seat, and the mounting seat is movably sleeved on the outside of the shielding cloth.

[0014] In the present utility model, for the anti-seismic structure of a high-power vehicle-mounted gas engine set, through the shock-absorbing steel plate, the purpose of primary shock absorption can be achieved. At the same time, due to the rotating connecting rods in the first anti-seismic unit, whether it is vertical vibration or horizontal vibration, it will cause the connecting rods to deflect. When the connecting rods deflect, it will drive the slider to have a lateral displacement, and cause the first spring to deform. At the same time, the first damper is in a state of being stretched or compressed. Therefore, under the action of the first spring and the first damper, the purpose of secondary shock absorption for vertical vibration and horizontal vibration can be achieved, making the anti-seismic effect better.

[0015] In the present utility model, for the anti-seismic structure of a high-power vehicle-mounted gas engine set, when vertical vibration occurs, through the arrangement of the second damper and the third spring in the second anti-seismic unit, the vertical vibration can be further shock-absorbed and offset. When horizontal vibration occurs, the fixed seat and the moving seat will move horizontally. During the horizontal movement, it will drive the damping rings to slide dampingly on the outside of the guide rod, and the rubber damping pad to slide dampingly in the chute. At the same time, the second springs will deform. Therefore, the effect of further shock-absorbing and offsetting the horizontal vibration can be achieved.

[0016] The structure design of the utility model is reasonable. Under the combined action of the shock-absorbing steel plate, four first seismic units and four second seismic units, the vibration generated by the high-power vehicle-mounted gas engine set body can be multi-stage shock-absorbed and offset, resulting in better seismic resistance, ensuring the stability of the high-power vehicle-mounted gas engine set body during operation, increasing the service life, and having high reliability.

Detailed Description of the Preferred Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Refer to Figures 1-4, an anti-seismic structure of a high-power vehicle-mounted gas engine set, including the high-power vehicle-mounted gas engine set body 3, as well as a fixed seat 2 and a mounting seat 1 for anti-seismic use of the high-power vehicle-mounted gas engine set body 3. Four grooves 21 and four chutes 20 are formed in the top of the mounting seat 1. A first anti-seismic unit 22 is arranged between the groove 21, the mounting seat 1 and the fixed seat 2. A second anti-seismic unit 19 is arranged between the chute 20 and the fixed seat 2. The same damping steel plate 23 is fixedly connected between the mounting seat 1 and the fixed seat 2. Two ear plates 4 are fixedly connected to both sides of the high-power vehicle-mounted gas engine set body 3. A screw rod 5 is threadedly connected to the top of the ear plate 4. The ear plate 4 is fixedly connected to the top of the fixed seat 2 through the screw rod 5.

[0024] Further, the first anti-seismic unit 22 includes a first spring 8 fixedly connected to the inner wall of one side of the groove 21 and a first damper 7 fixedly connected to the top of the mounting seat 1. One end of the first damper 7 and the first spring 8 are fixedly connected to the same slider 9. The front side of the slider 9 is rotatably connected to a connecting rod 11. The top end of the connecting rod 11 is rotatably connected to the bottom of the fixed seat 2. Due to the rotating connecting rod 11 in the first anti-seismic unit 22, whether it is vertical vibration or horizontal vibration, it will cause the connecting rod 11 to deflect. When the connecting rod 11 deflects, it will drive the slider 9 to have a lateral displacement, and cause the first spring 8 to deform. At the same time, the first damper 7 is in a state of being stretched or compressed. Therefore, under the action of the first spring 8 and the first damper 7, the purpose of secondary damping for vertical vibration and horizontal vibration can be achieved.

[0025] Further, four connecting plates 10 are fixedly connected to the bottom of the fixed seat 2. The four connecting rods 11 are respectively rotatably connected to the front sides of the corresponding connecting plates 10. The slider 9 is slidably sleeved in the groove 21, which can guide the slider 9 and is also conducive to rotatably connecting the connecting rod 11 to the bottom of the fixed seat 2.

[0026] Further, the second seismic unit 19 includes two second springs 16. One end of each of the two second springs 16 away from each other is fixedly connected to the inner walls on both sides of the sliding groove 20. One end of the two second springs 16 close to each other is fixedly connected to the same moving seat 12. A third spring 18 and a second damper 17 are fixedly connected to the top of the moving seat 12. The tops of the third spring 18 and the second damper 17 are both fixedly connected to the bottom of the fixed seat 2. A rubber damping pad 13 is fixedly sleeved on the outside of the moving seat 12. The rubber damping pad 13 is slidably and dampingly sleeved in the sliding groove 20. Damping rings 14 are fixedly connected to both sides of the moving seat 12. A guide rod 15 is fixedly connected to the inner walls on both sides of the sliding groove 20. Both of the two damping rings 14 are slidably and dampingly sleeved on the outside of the guide rod 15. Both of the two second springs 16 are sleeved on the outside of the guide rod 15. When vertical vibration occurs, through the arrangement of the second damper 17 and the third spring 18 in the second seismic unit 19, the vertical vibration can be further damped and offset. When lateral vibration occurs, the fixed seat 2 and the moving seat 12 will undergo lateral displacement. Under the lateral displacement, the damping rings 14 will be driven to slide dampingly on the outside of the guide rod 15, and the rubber damping pad 13 will slide dampingly in the sliding groove 20. At the same time, the second springs 16 will deform, so as to further damp and offset the lateral vibration.

[0027] Further, a shielding cloth 6 is fixedly sleeved on the outside of the fixed seat 2. The mounting seat 1 is movably sleeved on the outside of the shielding cloth 6. Through the shielding cloth 6, the appearance of the device is made simpler and neater, making the appearance of the device more beautiful. At the same time, the components between the fixed seat 2 and the mounting seat 1 can be shielded and protected.

[0028] In the present utility model, during use, the arrangement of the ear plate 4 and the screw rod 5 facilitates the installation of the high-power vehicle-mounted gas engine set on the top of the fixed seat 2. Through the shock-absorbing steel plate 23 (similar to the shock-absorbing steel plate on an automobile), the purpose of primary shock absorption can be achieved. At the same time, due to the rotating connecting rod 11 in the first shock-resistant unit 22, whether it is vertical vibration or horizontal vibration, it will cause the connecting rod 11 to deflect. When the connecting rod 11 deflects, it will drive the slider 9 to have a lateral displacement, and cause the first spring 8 to deform. At the same time, the first damper 7 is in a state of being stretched or compressed. Therefore, under the action of the first spring 8 and the first damper 7, the purpose of secondary shock absorption for vertical vibration and horizontal vibration can be achieved, making the shock-resistant effect better. At the same time, when vertical vibration occurs, through the arrangement of the second damper 17 and the third spring 18 in the second shock-resistant unit 19, the vertical vibration can be further shock-absorbed and offset. When horizontal vibration occurs, the fixed seat 2 and the movable seat 12 will have a lateral movement. During the lateral movement, it will drive the damping ring 14 to slide dampingly on the outside of the guide rod 15, and the rubber damping pad 13 to slide dampingly in the chute 20. At the same time, the second spring 16 will deform. Therefore, the effect of further shock-absorbing and offsetting the horizontal vibration can be achieved. Thus, under the action of the shock-absorbing steel plate 23, the four first shock-resistant units 22 and the four second shock-resistant units 19, the vibration generated by the high-power vehicle-mounted gas engine set body 3 can be shock-absorbed and offset multiple times, making the shock-resistant effect better, ensuring the stability of the high-power vehicle-mounted gas engine set body 3 during operation, and at the same time increasing the service life of the high-power vehicle-mounted gas engine set body 3.
