Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision of transport vehicles, in particular to an anti-collision device for a dangerous goods transport vehicle. Background Art

[0002] Dangerous goods are a general term for items that are flammable, explosive, and highly corrosive. Any items with corrosive, natural, flammable, toxic, or explosive properties are prone to accidents if not properly protected during transportation, loading and unloading, and storage. The consequences of these accidents are more serious than those of general vehicle accidents. Anti-collision protection is an important aspect of the transportation of dangerous goods, as collisions can easily lead to leakage and explosion of dangerous goods, resulting in significant casualties.

[0003] Publication number CN219056202U describes a collision avoidance device for hazardous materials transport vehicles, comprising a base plate; a fixed cylinder fixedly mounted on the upper end of the base plate; a support plate fixedly mounted on the outer side of the fixed cylinder; a lifting assembly disposed on the inner side of the fixed cylinder; a movable cylinder fixedly mounted on the upper end of the lifting assembly; a cross plate fixedly mounted on the outer side of the movable cylinder; and a buffer assembly fixedly mounted on the outer side of the base plate. This collision avoidance device for hazardous materials transport vehicles simply uses the lifting assembly to move the movable cylinder up and down, with energy-absorbing cushions providing initial energy absorption. When the protective plate is impacted, the buffer assembly cushions the impact force, thus achieving adjustable and protective equipment.

[0004] Although the above-mentioned anti-collision device solves certain problems, it still has the following disadvantages:

[0005] (1) The existing anti-collision device buffers the external force acting along the axial direction of the limit cylinder through the energy-absorbing cushion connected to the protection plate under the elastic support of the buffer component. The external force acting on the energy-absorbing cushion is mainly converted into the mechanical potential energy of the spring through four springs, and the buffering effect provided is not good enough.

[0006] (2) The existing anti-collision device can only provide a buffering function axially along the direction of the limiting cylinder through the limiting rod, and the buffering direction is relatively single. Utility Model Content

[0032] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0033] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Example 1:

[0035] like Figures 1 to 5 As shown, this embodiment proposes an anti-collision device for a dangerous goods transport vehicle, including a mounting plate 1, a slider 2, a connecting rod 3, a shock-absorbing wheel mechanism 4, a buffer assembly 5, a slide rail 6, a guide rod 7 and a rotating shaft 9 connected to the front end of the connecting rod 3.

[0036] Among them, the mounting plate 1 serving as the mounting base has mounting holes 11 at the upper and lower ends and the four corners on both sides of the front end. The mounting plate 1 can be installed on the inner side of the transport vehicle compartment by bolts. The mounting plate 1 is fixedly connected to the slide rail 6 on the upper and lower sides facing the interior of the compartment. The interior of the slide rail 6 is in a convex shape. A guide rod 7 is provided inside the slide rail 6. The two ends of the guide rod 7 are respectively fixedly connected to the two sides of the interior of the slide rail 6. A number of evenly distributed sliders 2 are provided on the outside of the slide rail 6 facing the interior of the compartment. The slider 2 is in an I-shape. The slider 2 is stuck at one end inside the slide rail 6 and has a guide hole 8 on one side. The slider 2 is sleeved on the outside of the guide rod 7 through the guide hole 8, and the slider 2 can move on the slide rail 6.

[0037] The sliders 2 on the slide rail 6 are grouped in pairs, and each slider 2 is hinged to a connecting rod 3 at one end facing the interior of the car. The connecting rods 3 on the two adjacent sliders 2 are staggered one above and one below, and the front ends of the connecting rods 3 connected to the front ends of the sliders 2 that are grouped in pairs are stacked together, and the front ends of the two connecting rods 3 are hinged together with a rotating shaft 9. The two sliders 2, the two connecting rods 3 and the rotating shaft 9 form a triangle with one side that can change in length. When there is an extrusion force on the rotating shaft 9 in the direction of the mounting plate 1, the distance between the rotating shaft 9 and the mounting plate 1 will become shorter, while the length of the connecting rod 3 remains unchanged, so the two sliders 2 connected to the rear end of the connected connecting rod 3 will move away from each other, converting the extrusion of the rotating shaft 9 into sliding of the slider 2 along the guide rod 7.

[0038] Several main shock-absorbing springs 501 and auxiliary shock-absorbing springs 502 are sleeved on the guide rod 7. The main shock-absorbing springs 501 are shorter and the auxiliary shock-absorbing springs 502 are longer. The auxiliary shock-absorbing springs 502 are arranged between the sliders 2 that form a group of two. The two sliders 2 are connected together by the longer shock-absorbing springs 502, and the other sliders 2 are connected together by the shorter main shock-absorbing springs 501. The two outermost sliders 2 and the side walls inside the slide rail 6 are also connected together by the main shock-absorbing springs 501. When the rotating shaft 9 is subjected to an extrusion force in the direction of the mounting plate 1, the sliders 2 sleeved on the guide rod 7 move to both sides. Under the tension or compression of the main shock-absorbing springs 501 and the auxiliary shock-absorbing springs 502, the impact force on the rotating shaft 9 is converted into mechanical potential energy of the spring.

[0039] Example 2:

[0040] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0041] In order to increase the cushioning that the rotating shaft 9 can provide and reduce the impact of the rotating shaft 9 on the transported dangerous goods, a rotor-shaped inner wheel 401 is rotatably connected to the upper and lower ends of the rotating shaft 9, and an outer wheel 402 is covered on the outside of the inner wheel 401. The inner wheel 401 and the outer wheel 402 are connected together through three evenly distributed shock absorbers 403. One end of the shock absorber 403 is hinged to the outer wall of the inner wheel 401, and the other end of the shock absorber 403 is hinged to the inner wall of the outer wheel 402. The outer wheel 402 and the inner wheel 401 can move and rotate synchronously to protect the outer shell of the transported dangerous goods from impact. In addition, an inflatable rubber ring 10 is fixedly connected to the outside of each outer wheel 402 to reduce the rigid contact between the outer wheel 402 and the outer shell of the transported dangerous goods.

[0042] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
