Description

Technical Field

[0001] The present invention relates to the technical field of gas cylinder fixing, and specifically relates to a vibration-damping truck LNG double-layer gas cylinder frame. Background Art

[0002] In the field of truck transportation, liquefied natural gas (LNG), as a clean energy source, is increasingly widely used. To meet the needs of long-distance transportation, trucks usually need to load LNG gas cylinders with a large capacity.

[0003] Existing truck LNG gas cylinder frames mostly adopt simple fixing methods such as bolt fastening. Although these methods can achieve the basic fixing function, there are some deficiencies. First, the installation and disassembly processes of the bolt fastening method are cumbersome and time-consuming, and are not suitable for occasions where the gas cylinder needs to be frequently replaced. Second, long-term use may cause the bolts to loosen, affecting the fixing effect and even possibly causing the gas cylinder to accidentally fall off. In addition, the rigid connection of the fixing may cause resonance between the gas cylinder and the vehicle structure, increasing the risk of gas cylinder damage.

[0004] To solve these problems, a new type of vibration-damping truck LNG gas cylinder frame is needed. This frame can effectively absorb and reduce vibrations during driving while ensuring the stability of the gas cylinder, avoid resonance between the gas cylinder and the vehicle, and improve the safety and stability of the gas cylinder. In addition, the new frame should facilitate the rapid loading and unloading of the gas cylinder, improve transportation efficiency, and avoid potential risks caused by the failure of the fixing structure.

[0005] Therefore, developing a new type of vibration-damping truck LNG gas cylinder frame that can provide a safer, more stable, and more convenient gas cylinder fixing solution has become an urgent need for the industry's development. Summary of the Invention

[0006] The present invention provides a vibration-damping truck LNG double-layer gas cylinder frame, which solves the problems mentioned in the above background art.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A vibration-damping truck LNG double-layer gas cylinder frame includes a load-bearing frame. There are two load-bearing frames symmetrically arranged. A reinforcing plate is fixedly connected to the inner surface of the load-bearing frame. Protective plates are fixedly connected to both ends of the load-bearing frame. An installation frame is fixedly connected to the outer surface of the top of the load-bearing frame. The frame further includes:

[0008] A fixing mechanism, which is fixedly installed on the installation frame and is arranged inside the protective plate. The fixing mechanism is used to fix the LNG gas cylinder;

[0009] An auxiliary mechanism, which is fixedly installed on the fixing mechanism and is used to cooperate with the fixing mechanism to work;

[0010] The fixing mechanism includes a fixing plate, the fixing plate is symmetrically and fixedly connected to the outer surfaces on both sides of the mounting frame, four of the fixing plates are set as a group, there are two groups of the fixing plates, the top of the fixing plate is symmetrically and fixedly connected with a bearing plate, four bearing plates are arranged on the same fixing plate, and two bearing plates are set as a group. The two bearing plates are combined into a nearly circular ring shape. The outer surfaces on both sides of the bearing plate are fixedly connected with a support plate, the upper surface of the support plate is fixedly connected with a sliding rod, and a threaded rod is arranged through the upper surface of the inner support plate, and the threaded rod is in threaded connection with the upper support plate.

[0011] The top of the threaded rod is rotationally connected with a motor, the top of the motor is fixedly connected with a connecting plate, and the connecting plate is fixedly connected to the top of the mounting frame. When it is necessary to fix the LNG gas cylinder, the LNG gas cylinder can be inserted between the bearing plates on the same central axis. At this time, the LNG gas cylinder is placed on the lower bearing plate. After the four LNG gas cylinders are placed in sequence, the motor can be started. After the motor is started, it will drive the threaded rod to rotate. When the threaded rod starts to rotate, the upper support plate and the sliding rod will move downward through the thread, that is, finally the upper bearing plate will move downward to cooperate with the lower bearing plate to clamp and fix the LNG gas cylinder. Reversing the motor can cancel the fixation of the LNG gas cylinder.

[0012] Preferably, a moving plate is arranged on the inner side of the bearing plate. The moving plate is arranged parallel to the bearing plate. The moving plate is arc-shaped. The moving plate and the bearing plate are concentric. Both ends of the moving plate are fixedly connected with sliding plates, and the sliding plates are slidably sleeved on the outer surface of the sliding rod.

[0013] Preferably, an inner cushion plate is fixedly connected to the inner surface of the middle part of the moving plate, an outer cushion plate is fixedly connected to the outer surface of the middle part of the moving plate, elastic plates are symmetrically fixedly connected to the outer surface of the outer cushion plate, and the outer surfaces of the elastic plates are fixedly attached to the inner surface of the bearing plate.

[0014] Preferably, sliding grooves are symmetrically formed through the inner surfaces on both sides of the moving plate. Sliding plates are slidably connected in the sliding grooves. One end of the sliding plate away from the bearing plate is fixedly connected with a covering plate. The cross section of the covering plate is nearly U-shaped, and the inner side of the covering plate is bent away from the moving plate.

[0015] Preferably, an inclined plate is fixedly connected to the inner surface of the cladding plate, and a push plate is fixedly connected to the outer surface of the cladding plate on the side close to the inner backing plate. The push plate is arranged in a sliding groove. A telescopic plate is fixedly connected to the surface of the push plate on the side close to the outer backing plate. One end of the telescopic plate away from the push plate is fixedly connected to the outer backing plate. A rubber tube is fixedly connected to the outer surface of the outer backing plate. The rubber tube is arranged as a closed tube. The internal cavity of the rubber tube communicates with the internal cavity of the telescopic plate. The inside of the inner backing plate is hollow, and the internal cavity of the inner backing plate communicates with the internal cavity of the telescopic plate. Since the moving plate is arranged inside the bearing plate, when the two bearing plates approach each other, the moving plates will approach each other, and then the end of the cladding plate will contact the LNG cylinder first. As the extrusion force increases, the side of the cladding plate close to the LNG cylinder will gradually bend outward, and finally the outer surface of the cladding plate will fit on the outer surface of the LNG cylinder. As the extrusion force continues to increase, the LNG cylinder will contact the outer surface of the inner backing plate and exert pressure on the inner backing plate, and through the inner backing plate and the moving plate, the elastic plate will be extruded, and then the rubber tube on the surface of the outer backing plate will also be extruded, so that the inner backing plate and the rubber tube will convey the air pressure in their internal cavities to the telescopic plate to promote the telescopic plate to extend outward, and then push the cladding plate along the sliding groove to the outside through the push plate, so that the upper and lower cladding plates approach each other, that is, cooperate with the inner backing plate to perform breakpoint-type all-round cladding and fixing on the outer surface of the LNG cylinder, so that the LNG cylinder and the moving plate form a relative whole.

[0016] Preferably, the auxiliary mechanism includes a driving plate arranged inside the cladding plate. A plugging rod is fixedly connected to the surface of the driving plate on the side away from the inclined plate. The plugging rod slidably penetrates through one side of the cladding plate close to the moving plate.

[0017] Preferably, one end of the plugging rod away from the driving plate is fixedly connected to an extrusion plate. A pressure capsule is fixedly connected to the outer surface of the extrusion plate. An auxiliary plate is fixedly connected to the outer surface of the pressure capsule on the side away from the extrusion plate. The auxiliary plate is arranged outside the moving plate. An auxiliary rod is fixedly connected to the auxiliary plate. Rotating rollers are rotatably connected to both ends of the auxiliary rod. Connecting pipes are fixedly connected to the outer ends of the rotating rollers. Sealing pipes are fixedly connected to the outer ends of the connecting pipes.

[0018] Preferably, air pressure holes are formed through the outer surface of the connecting pipe. An expansion pipe is arranged outside the connecting pipe. Both ends of the expansion pipe are respectively fixedly connected to the rotating roller and the sealing pipe. The internal cavity of the connecting pipe communicates with the internal cavity of the pressure capsule.

[0019] The present invention provides a vibration-damping truck LNG double-layer cylinder frame, which has the following beneficial effects:

[0020] 1. In this shock-absorbing LNG double-layer gas cylinder frame for trucks, through the cooperation between the motor and the threaded rod, when the threaded rod rotates, all LNG gas cylinders can be clamped and fixed, and reversing the motor can also release the fixation of all LNG gas cylinders, realizing the operations of quick fixation and removal. Compared with the existing method of fixing with bolts, it not only avoids the disadvantages of cumbersome and time-consuming fixation, but also can avoid the problem of poor fixation effect caused by the slipping of bolts.

[0021] 2. In this shock-absorbing LNG double-layer gas cylinder frame for trucks, through the elastic force of the elastic plate, the LNG gas cylinder and the bearing plate are elastically fixed. Then, when the vehicle is working, the LNG gas cylinder connected to the moving plate can have a small amplitude of shaking, thus avoiding the situation in the prior art where the LNG gas cylinder is fixedly connected to the mounting frame, resulting in resonance between the LNG gas cylinder and the vehicle, greatly reducing the amplitude of vibration of the LNG gas cylinder with the vehicle, thereby improving the stability of the LNG gas cylinder during operation. When the covering plate is extruded and bent outward, the inclined plate will be gradually extruded, and then a reverse supporting force is formed on the covering plate, further greatly increasing the extrusion force between the covering plate and the LNG gas cylinder, thereby improving the fixation effect on the LNG gas cylinder.

[0022] 3. In this shock-absorbing LNG double-layer gas cylinder frame for trucks, when the inclined plate is extruded, it will extrude the driving plate, and then through the insertion rod, the extrusion plate at the outer end of the insertion rod will extrude the pressure capsule. When the pressure capsule is extruded, it will convey the internal air pressure to the inner cavity of the connecting pipe. Then, the pressure in the inner cavity of the connecting pipe will increase, and it will be released outward through the air pressure holes on the connecting pipe, causing the expansion pipe to expand outward, gradually increasing the friction force between the rotating roller and the moving plate, stopping the rotation of the rotating roller, thereby restricting the movement amplitude of the covering plate, avoiding excessive movement of the covering plate resulting in contact extrusion between the upper and lower covering plates, and thus causing the two ends of the covering plate to warp up and reducing the clamping and fixing effect on the LNG gas cylinder. Due to the existence of the rotating roller, when the covering plate initially slides outward, the friction resistance can be greatly reduced, facilitating the movement of the covering plate and avoiding non-uniform movement caused by the pressure between the inner side of the covering plate and the LNG gas cylinder, reducing the working stability.

Specific Embodiment

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The first embodiment: As Figures 1 to 8 shown, the present invention provides a technical solution: a vibration-damping truck LNG double-layer gas cylinder frame, including a load-bearing frame 1, two load-bearing frames 1 are symmetrically arranged, a reinforcing plate 2 is fixedly connected to the inner surface of the load-bearing frame 1, protection plates 3 are fixedly connected to both ends of the load-bearing frame 1, a mounting bracket 4 is fixedly connected to the outer surface of the top of the load-bearing frame 1, and further includes:

[0034] A fixing mechanism 5, the fixing mechanism 5 is fixedly installed on the mounting bracket 4, the fixing mechanism 5 is arranged inside the protection plate 3, and the fixing mechanism 5 is used for fixing the LNG gas cylinder;

[0035] An auxiliary mechanism 6, the auxiliary mechanism 6 is fixedly installed on the fixing mechanism 5, and the auxiliary mechanism 6 is used to cooperate with the fixing mechanism 5 to work;

[0036] Among them, the fixing mechanism 5 includes a fixing plate 51, and the fixing plate 51 is symmetrically and fixedly connected to the outer surfaces on both sides of the mounting bracket 4. Four fixing plates 51 are set as a group, and there are two groups of fixing plates 51. The top of the fixing plate 51 is symmetrically and fixedly connected with a bearing plate 52. Four bearing plates 52 are arranged on the same fixing plate 51. Two bearing plates 52 are set as a group, and the two bearing plates 52 are combined into a nearly circular ring shape. The outer surfaces on both sides of the bearing plate 52 are fixedly connected with a support plate 53, and the upper surface of the support plate 53 is fixedly connected with a sliding rod 54. A threaded rod 55 is arranged through the upper surface of the inner support plate 53, and the threaded rod 55 is threadedly connected with the upper support plate 53.

[0037] The top of the threaded rod 55 is rotatably connected with a motor 56, and the top of the motor 56 is fixedly connected with a connecting plate 57, and the connecting plate 57 is fixedly connected to the top of the mounting bracket 4.

[0038] During work, when it is necessary to fix the LNG gas cylinder, the LNG gas cylinder can be inserted between the bearing plates 52 on the same central axis. At this time, the LNG gas cylinder is placed on the lower bearing plate 52. After the four LNG gas cylinders are placed in sequence, the motor 56 can be started. After the motor 56 is started, it will drive the threaded rod 55 to rotate. When the threaded rod 55 starts to rotate, the upper support plate 53 and the sliding rod 54 will move downward through the thread, that is, finally the upper bearing plate 52 will move downward to cooperate with the lower bearing plate 52 to clamp and fix the LNG gas cylinder. Reversing the motor 56 can cancel the fixation of the LNG gas cylinder. Through the cooperation between the motor 56 and the threaded rod 55, when the threaded rod 55 rotates, all the LNG gas cylinders can be clamped and fixed, and reversing the motor 56 can also cancel the fixation of all the LNG gas cylinders, realizing the operations of quick fixation and removal. Compared with the existing fixation by bolts, it not only avoids the disadvantages of cumbersome and time-consuming fixation, but also can avoid the problem of poor fixation effect caused by the thread slipping of the bolts.

[0039] Second embodiment: As Figures 1 to 8 shown, a moving plate 58 is arranged on the inner side of the bearing plate 52. The moving plate 58 is arranged parallel to the bearing plate 52. The moving plate 58 is arc-shaped, and the moving plate 58 and the bearing plate 52 are concentric. The two ends of the moving plate 58 are fixedly connected with a sliding plate 59, and the sliding plate 59 is slidably sleeved on the outer surface of the sliding rod 54.

[0040] The inner surface of the middle part of the moving plate 58 is fixedly connected with an inner cushion plate 510, the outer surface of the middle part of the moving plate 58 is fixedly connected with an outer cushion plate 511, and the outer surface of the outer cushion plate 511 is symmetrically and fixedly connected with an elastic plate 512. The outer surface of the elastic plate 512 is fixedly attached to the inner surface of the bearing plate 52.

[0041] On both inner surfaces of the moving plate 58, sliding grooves 513 are symmetrically formed through. A sliding plate 514 is slidably connected in the sliding groove 513. One end of the sliding plate 514 away from the bearing plate 52 is fixedly connected with a covering plate 515. The cross-section of the covering plate 515 is set to be nearly U-shaped, and the inner side of the covering plate 515 is bent away from the moving plate 58.

[0042] On the inner surface of the covering plate 515, an inclined plate 516 is fixedly connected. On the outer surface of the covering plate 515 near the inner cushion plate 510, a push plate 517 is fixedly connected. The push plate 517 is arranged in the sliding groove 513. On the surface of the push plate 517 near the outer cushion plate 511, a telescopic plate 518 is fixedly connected. One end of the telescopic plate 518 away from the push plate 517 is fixedly connected to the outer cushion plate 511. On the outer surface of the outer cushion plate 511, a rubber tube 519 is fixedly connected. The rubber tube 519 is set as a closed tube. The internal cavity of the rubber tube 519 is communicated with the internal cavity of the telescopic plate 518. The inside of the inner cushion plate 510 is hollow, and the internal cavity of the inner cushion plate 510 is communicated with the internal cavity of the telescopic plate 518.

[0043] During operation, since the movable plate 58 is arranged on the inner side of the supporting plate 52, when the two supporting plates 52 are close to each other, the movable plates 58 will be close to each other, so that the end of the covering plate 515 will first contact the LNG cylinder, and as the squeezing force increases, the side of the covering plate 515 close to the LNG cylinder will gradually bend outward, and finally the outer surface of the covering plate 515 will fit the outer surface of the LNG cylinder, and as the squeezing force continues to increase, the LNG cylinder will contact the outer surface of the inner pad 510, and squeeze the inner pad 510, and squeeze the elastic plate 512 through the inner pad 510 and the movable plate 58, so that the rubber tube 519 on the surface of the outer pad 511 is also squeezed, so that the inner pad 510 and the rubber tube 519 transmit the internal cavity air pressure to the telescopic plate 518, so that the telescopic plate 518 is stretched outward, and then the covering plate 515 is pushed outward along the slide groove 513 through the pushing plate 517 The LNG cylinder is fixed to the supporting plate 52 by the elastic force of the elastic plate 512, so that the LNG cylinder connected to the supporting plate 52 can be slightly shaken when the vehicle is working, thereby avoiding the resonance between the LNG cylinder and the vehicle caused by the fixed connection between the LNG cylinder and the mounting frame 4 in the prior art, greatly reducing the amplitude of the vibration of the LNG cylinder with the vehicle, thereby improving the stability of the LNG cylinder when working, and when the cladding plate 515 is squeezed and bent outward, the inclined plate 516 is gradually squeezed, thereby forming a reverse supporting force on the cladding plate 515, thereby greatly increasing the squeezing force between the cladding plate 515 and the LNG cylinder, thereby improving the fixing effect of the LNG cylinder.

[0044] The third embodiment: Figures 1 to 8 As shown, the auxiliary mechanism 6 includes a driving plate 61, which is arranged on the inner side of the covering plate 515. The surface of the driving plate 61 away from the inclined plate 516 is fixedly connected with a plug-in rod 62, and the plug-in rod 62 slides through the side of the covering plate 515 close to the movable plate 58.

[0045] One end of the plug-in rod 62 away from the driving plate 61 is fixedly connected to the extrusion plate 63, the outer surface of the extrusion plate 63 is fixedly connected to the pressure bag 64, the outer surface of the pressure bag 64 away from the extrusion plate 63 is fixedly connected to the auxiliary plate 65, the auxiliary plate 65 is arranged on the outer side of the movable plate 58, the auxiliary plate 65 is fixedly connected to the auxiliary rod 66, the two ends of the auxiliary rod 66 are rotatably connected to rotating rollers 67, the outer end of the rotating roller 67 is fixedly connected to a connecting tube 68, and the outer end of the connecting tube 68 is fixedly connected to a sealing tube 69.

[0046] The outer surface of the connecting pipe 68 is penetrated with air pressure holes 610. An expansion pipe 611 is arranged outside the connecting pipe 68. The two ends of the expansion pipe 611 are respectively fixedly connected to the rotating roller 67 and the sealing pipe 69. The internal cavity of the connecting pipe 68 is communicated with the internal cavity of the pressure bladder 64.

[0047] During operation, when the inclined plate 516 is squeezed, it will squeeze the driving plate 61, and then through the inserting rod 62, the squeezing plate 63 at the outer end of the inserting rod 62 will squeeze the pressure bladder 64. When the pressure bladder 64 is squeezed, it will convey the internal air pressure to the inner cavity of the connecting pipe 68, so that the pressure in the inner cavity of the connecting pipe 68 increases, and then it will be released outward through the air pressure holes 610 on the connecting pipe 68, so that the expansion pipe 611 expands outward, that is, gradually increases the friction force between the rotating roller 67 and the moving plate 58, and stops the rotating roller 67, thereby restricting the moving range of the covering plate 515, avoiding the contact extrusion between the upper and lower covering plates 515 caused by excessive movement of the covering plate 515, and thus causing the two ends of the covering plate 515 to warp up and reducing the clamping and fixing effect on the LNG gas cylinder. Due to the existence of the rotating roller 67, the friction resistance can be greatly reduced when the covering plate 515 slides outward initially, so as to facilitate the movement of the covering plate 515 and avoid the non-uniform movement caused by the pressure between the inner side of the covering plate 515 and the LNG gas cylinder and reduce the working stability.
