Description

Technical Field

[0001] This utility model relates to the field of anti-collision technology for transport liquid tanks, specifically an anti-collision energy absorption device for a transport liquid tank assembly. Background Technology

[0002] Tank assemblies are commonly used transport equipment in the transportation of liquid goods. However, during transportation, vehicles may encounter various collisions, such as rear-end collisions and frontal collisions. Because the tanks contain a large amount of liquid, the enormous impact force in a collision can cause the tanks to move, easily leading to damage, deformation, or even liquid leakage. This can cause environmental pollution, resource waste, and, in more serious cases, fires, explosions, and other safety accidents, endangering lives and property.

[0003] However, existing technologies still have significant shortcomings, such as:

[0004] In the existing technology: some anti-collision structures on the market have relatively simple functions, focusing only on providing anti-collision protection for liquid tanks. However, when the transport vehicle is hit or makes a sudden braking operation, because the liquid tank is filled with a large amount of liquid, the liquid sloshing under the action of inertia will cause the liquid tank to move as a whole. This movement of the liquid tank poses a great safety hazard and is very likely to cause impact to the cab. Utility Model Content

[0005] The purpose of this invention is to provide an anti-collision energy absorption device for a transport liquid tank assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a collision-resistant energy-absorbing device for a transport liquid tank assembly, comprising a base and a liquid tank assembly mounted on its top, wherein a collision-resistant energy-absorbing mechanism is mounted on the top of the base and on both sides of the liquid tank assembly for absorbing energy from collisions to the liquid tank assembly.

[0007] The anti-collision energy absorption mechanism includes external anti-collision brackets fixedly installed on both sides of the top of the base. An internal anti-impact bracket is fixedly installed on the top of the base and on one side of the two external anti-collision brackets. An anti-collision mechanism for anti-collision is installed between the external anti-collision brackets and the internal anti-impact brackets.

[0008] The anti-collision mechanism is equipped with an auxiliary mechanism inside to absorb energy when the liquid tank assembly is impacted.

[0009] Preferably, a first guide rail is fixedly installed on the side adjacent to the external anti-collision bracket and the internal anti-impact bracket, and a slide block is slidably installed on the top and bottom of the two first guide rail surfaces, and a first spring is fixedly installed between the slide blocks;

[0010] Each of the slides is equipped with a pivot seat on one side, and a scissor bar is hinged between the pivot seats.

[0011] Preferably, a fixing plate is fixedly installed on the inner wall of the external anti-collision bracket, and an arc-shaped anti-collision plate is provided on the inner wall of the internal anti-impact bracket. A fixing seat is installed between the fixing plate and the arc-shaped anti-collision plate.

[0012] A sleeve rod is fixedly installed at the top and bottom between the two fixed seats. A sliding rod is installed through each pair of sleeve rods, and a slider is fixedly installed at one end of the sliding rod inside the sleeve rod. A rubber energy-absorbing pad is fixedly installed between the slider and the sleeve rod.

[0013] Preferably, the auxiliary mechanism includes four piston cylinders fixedly installed on one side of the fixed plate. A piston plate is slidably installed inside the piston cylinder. A piston rod is fixedly installed on one side of the piston plate. One end of the piston rod passes through the piston cylinder and extends to the outside of the piston cylinder. A rubber rod is fixedly installed at the end of the piston rod located outside the piston cylinder. A second spring is fixedly installed on the other side of the piston plate.

[0014] Preferably, an airbag is fixedly installed on one side of the fixing plate and between the four piston cylinders. Both sides of the airbag are connected to horizontal tubes. The end of the horizontal tube away from the airbag is connected to a three-way tube. The top and bottom ends of the three-way tube are connected to vertical tubes, and the end of the vertical tube away from the three-way tube is connected to one side of the piston cylinder.

[0015] Preferably, a second guide rail is fixedly installed on both the top and bottom of one side of the fixing plate, and a sliding groove is provided on the side of the fixing seat near the fixing plate, and the fixing seat is slidably connected to the fixing plate through the sliding groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By utilizing the anti-collision mechanism, when the transport vehicle encounters a collision or performs a sudden braking operation, the liquid tank assembly impacts the arc-shaped anti-collision plate, causing the internal anti-impact bracket to move synchronously with the arc-shaped anti-collision plate. When the internal anti-impact bracket moves, the elastic cooperation between the pivot seat, the scissor bar, and the first spring provides initial buffering for the liquid tank assembly. When the arc-shaped anti-collision plate moves, the fixed seat on one side moves, squeezing the sleeve rod and the sliding rod, and causing the sliding rod to slide inside the sleeve rod. The deformation of the rubber energy-absorbing pad absorbs the impact force generated by the liquid tank assembly. In this way, when the liquid tank assembly moves inertial motion, it can prevent the liquid tank assembly from impacting the cab and affecting the safety of the driver and passengers.

[0018] 2. When the impact force on the liquid tank assembly is too large, the arc-shaped anti-collision plate compresses the airbag. When the airbag is under force, the gas inside it is injected into the piston cylinder through the connection between the horizontal and vertical pipes, pressurizing the inside of the piston cylinder and driving the piston plate and piston rod to move. This causes the rubber rod to move and block the arc-shaped anti-collision plate, thus preventing the arc-shaped anti-collision plate from hitting the fixed plate when the impact is too large, and further improving the impact resistance of this device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] Please see Figures 1-7 This utility model provides a technical solution: a collision-resistant energy-absorbing device for a transport liquid tank assembly, including a base 1 and a liquid tank assembly 2 mounted on top of the base 1. Collision-resistant energy-absorbing mechanisms 3 are installed on the top of the base 1 and on both sides of the liquid tank assembly 2 for collision-resistant energy absorption. The collision-resistant energy-absorbing mechanism 3 includes external collision-resistant brackets 31 fixedly installed on both sides of the top of the base 1. Internal anti-impact brackets 32 are fixedly installed on the top of the base 1 and on one side of the two external collision-resistant brackets 31. A collision-resistant mechanism 33 for collision protection is installed between the external collision-resistant brackets 31 and the internal anti-impact brackets 32. An auxiliary mechanism 34 is installed inside the collision-resistant mechanism 33 for energy absorption when the liquid tank assembly 2 is impacted.

[0030] The external anti-collision bracket 31 and the internal anti-impact bracket 32 ​​are each fixedly installed with a first guide rail 331 on one side. The top and bottom surfaces of the two first guide rails 331 are each slidably installed with a slide block 332. A first spring 333 is fixedly installed between several slide blocks 332. A pivot seat 334 is installed on one side of several slide blocks 332. A scissor bar 335 is hinged between several pivot seats 334.

[0031] In this embodiment, when the transport vehicle is hit or performs a sudden braking operation, the liquid tank assembly 2 impacts the arc-shaped anti-collision plate 337, causing the internal anti-impact bracket 32 ​​to move synchronously with the arc-shaped anti-collision plate 337. When the internal anti-impact bracket 32 ​​moves, it provides initial buffering for the liquid tank assembly 2 through the elastic cooperation between the pivot seat 334, the scissor bar 335, and the first spring 333.

[0032] A fixing plate 336 is fixedly installed on the inner side wall of the external anti-collision bracket 31, and an arc-shaped anti-collision plate 337 is provided on the inner side wall of the internal anti-impact bracket 32. A fixing seat 338 is installed between the fixing plate 336 and the arc-shaped anti-collision plate 337. A sleeve rod 339 is fixedly installed at the top and bottom between the two fixing seats 338. A sliding rod 3301 is installed through each two sleeve rods 339, and a slider 3302 is fixedly installed at one end of the slider 3301 inside the sleeve rod 339. A rubber energy-absorbing pad 3303 is fixedly installed between the slider 3302 and the sleeve rod 339.

[0033] In this embodiment, when the arc-shaped anti-collision plate 337 moves, the fixed seat 338 on one side moves to compress the sleeve rod 339 and the slide rod 3301, and drives the slide rod 3301 to slide inside the sleeve rod 339. The deformation of the rubber energy-absorbing pad 3303 absorbs the impact force generated by the liquid tank assembly 2. In this way, when the liquid tank assembly 2 moves inertially, the liquid tank assembly 2 will impact the cab and affect the safety of the driver and passengers.

[0034] The top and bottom of one side of the fixing plate 336 are fixedly installed with the second guide rail 3304, and the fixing seat 338 is provided with a sliding groove on the side near the fixing plate 336. The fixing seat 338 is slidably connected to the fixing plate 336 through the sliding groove.

[0035] Example 2:

[0036] Based on Embodiment 1, this embodiment takes into account that although Embodiment 1 can avoid the impact of the liquid tank assembly 2 on the cab, in actual use, the impact force will be different due to the different liquid loading in the liquid tank assembly 2. In order to avoid the impact of the liquid tank assembly 2 on the cab when the impact force is too large, this embodiment uses the following structure to further improve the anti-collision capability of the device.

[0037] The auxiliary mechanism 34 includes four piston cylinders 341 fixedly installed on one side of the fixed plate 336. A piston plate 342 is slidably installed inside the piston cylinder 341. A piston rod 343 is fixedly installed on one side of the piston plate 342. One end of the piston rod 343 passes through the piston cylinder 341 and extends to the outside of the piston cylinder 341. A rubber rod 344 is fixedly installed on the end of the piston rod 343 located outside the piston cylinder 341. A second spring 345 is fixedly installed on the other side of the piston plate 342. An airbag 346 is fixedly installed on one side of the fixed plate 336 and between the four piston cylinders 341. A horizontal tube 347 is connected to both sides of the airbag 346. A three-way tube 348 is connected to the end of the horizontal tube 347 away from the airbag 346. A vertical tube 349 is connected to the top and bottom of the three-way tube 348. The end of the vertical tube 349 away from the three-way tube 348 is connected to one side of the piston cylinder 341.

[0038] In this embodiment, when the impact force of the liquid tank assembly 2 is too large, the arc-shaped anti-collision plate 337 compresses the airbag 346. When the airbag 346 is subjected to force, the gas inside it is injected into the piston cylinder 341 through the connection between the horizontal pipe 347 and the vertical pipe 349, pressurizing the inside of the piston cylinder 341 and driving the piston plate 342 and piston rod 343 to move. This causes the rubber rod 344 to move and block the arc-shaped anti-collision plate 337, thereby preventing the arc-shaped anti-collision plate 337 from impacting the fixed plate 336 when the impact is too large, and further improving the impact resistance of this device.

[0039] Working principle: When the transport vehicle is hit or brakes suddenly, the liquid tank assembly 2 impacts the arc-shaped anti-collision plate 337, causing the internal anti-impact bracket 32 ​​to move synchronously with the arc-shaped anti-collision plate 337. When the internal anti-impact bracket 32 ​​moves, it provides initial buffering for the liquid tank assembly 2 through the elastic cooperation between the pivot seat 334, the scissor bar 335, and the first spring 333. When the arc-shaped anti-collision plate 337 moves, the fixed seat 338 on one side moves and compresses the sleeve rod 339 and the sliding rod 3301, causing the sliding rod 3301 to slide inside the sleeve rod 339. The deformation of the rubber energy-absorbing pad 3303 absorbs the impact force generated by the liquid tank assembly 2.

[0040] Furthermore, when the impact force of the liquid tank assembly 2 is too large, the arc-shaped anti-collision plate 337 compresses the airbag 346. When the airbag 346 is under force, the gas inside it is injected into the piston cylinder 341 through the connection between the horizontal pipe 347 and the vertical pipe 349, which pressurizes the inside of the piston cylinder 341 and drives the piston plate 342 and the piston rod 343 to move. This allows the rubber rod 344 to move and block the arc-shaped anti-collision plate 337, so as to prevent the arc-shaped anti-collision plate 337 from impacting the fixed plate 336 when the impact is too large, thus further improving the impact resistance of the device.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
