[0045] Referring to Figure 1 and Figure 2 , the embodiments of the present application provide a transport vehicle, which can be a fire vehicle, a container truck or other vehicle requiring a tailgate assembly. When the transport vehicle is a fire vehicle, the fire vehicle is used to transport a tracked fire robot.

[0046] As shown in Figure 1 , the transport vehicle includes a chassis 40 and a tailgate assembly, and the tailgate assembly is rotationally connected to the tail of the chassis 40. As shown in Figure 2 , the tailgate assembly includes a tailgate component 10, a driving component 20 and a locking component 30.

[0047] The overall structure of the tailgate component 10 is a rectangular structure, and the tailgate component 10 is hinged to the chassis 40 of the transport vehicle through a hinge, a pin shaft or the like, and is located at the tail of the chassis 40. The tailgate component 10 is used to load and unload the tracked fire robot, or to bear the large weight of the tracked fire robot, as a bearing platform for the transportation of the tracked fire robot.

[0048] The driving component 20 can be a hydraulic cylinder, which converts hydraulic energy into mechanical energy and is a hydraulic executing element moving linearly and reciprocally.

[0049] In the suspended state, the tail plate component 10 is away from the ground by a certain distance, and the tail plate component 10 is approximately parallel to the ground, at this time, the tail plate component 10 serves as a load-carrying platform for the tracked fire-fighting robot, and carries the large weight of the tracked fire-fighting robot.

[0050] The locking component 30 comprises a driving piece 31 and a locking piece 32, the locking piece 32 is rotationally connected to the chassis 40 and connected with the driving piece 31, the driving piece 31 is installed to the chassis 40, and the driving piece 31 is suitable for driving the locking piece 32 to switch between the locking state and the unlocking state, in the locking state, the locking piece 32 is hooked to the tail plate component 10, so that the tail plate component 10 is kept in the suspended state, and in the unlocking state, the locking piece 32 is separated from the tail plate component 10.

[0051] The driving piece 31 can also be a hydraulic cylinder, the driving piece 31 is vertically fixed in the middle of the chassis 40 through a fixing piece, the driving piece 31 controls the up-down movement through a hydraulic reversing valve, and the locking and opening of the tail plate body 11 are realized.

[0052] Since the driving component 20 driving the tail plate component 10 to move is also a hydraulic cylinder, the transport vehicle itself is provided with a hydraulic power source, and the control of the driving piece 31 can be realized by additionally arranging a hydraulic pipeline between the original hydraulic power source and the driving piece 31, so that the locking piece 32 is switched between the locking state and the unlocking state, and the method is simple and practical.

[0053] It can be understood that the tail plate assembly provided by the embodiment of the utility model, by installing the locking component 30 on the chassis 40 of the transport vehicle, the locking component 30 comprises a driving piece 31 and a locking piece 32, the locking piece 32 is connected to the output end of the driving piece 31, the driving piece 31 is suitable for driving the locking piece 32 to switch between the locking state and the unlocking state, in the locking state, the locking piece 32 is hooked to the tail plate component 10, so that the tail plate component 10 is kept in the suspended state, and in the unlocking state, the locking piece 32 is separated from the tail plate component 10.

[0054] In this way, when the tail plate component 10 is in the hanging state, the driving member 31 drives the locking member 32 to be hooked on the tail plate component 10, at this time, the locking member 32 restricts the tail plate component 10, and the internal leakage of the driving component 20 in a specified range can be compensated, so that the tail plate assembly is inclined or lowered, thereby improving the safety of the transport vehicle. When the tail plate component 10 is in the hanging state, not only the driving component 20 drives the locking tail plate component 10, but also the locking member 32 is mechanically locked to improve the reliability of the locking of the tail plate assembly. When the tail plate component 10 is in the inclined state, the driving member 31 drives the locking member 32 to be separated from the tail plate component 10, at this time, the driving component 20 can drive the tail plate component 10 to be freely lifted.

[0055] Figure 3 It is a top view of the tail plate assembly provided by the embodiment of the utility model. Figure 4 It is a sectional view of the tail plate assembly provided by the embodiment of the utility model.

[0056] Referring to Figure 3 and Figure 4 In some embodiments of the utility model, the locking member 32 is in a rod-shaped structure, the locking member 32 includes a locking main body 321 with a certain length, a hinged part 322 is arranged at one end of the locking main body 321, the width of the hinged part 322 is greater than the width of the locking main body 321, the reliability of the connection of the locking member 32 can be improved, and the hinged part 322 is rotatably connected with the chassis 40 of the transport vehicle through a pin shaft. A hooking part 323 is formed at the other end of the locking main body 321, the hooking part 323 can be hooked on the tail plate component 10 in the locking state, so that the tail plate component 10 is kept in the hanging state.

[0057] Preferably, the locking member 32 is integrally formed, and in order to facilitate the description of the structure of the locking member 32, the locking member 32 is divided into a locking main body 321, a hinged part 322 and a hooking part 323.

[0058] Continuing to refer to Figure 3 and Figure 4 In some embodiments of the utility model, the tail plate component 10 includes a tail plate main body 11 and a hinged seat 12; the tail plate main body 11 is hingedly connected to the chassis 40 of the transport vehicle through a hinge, and the hinged seat 12 is detachably connected to the hinged side of the tail plate main body 11 by welding or a bolt structure, and the hinged seat 12 is arranged at an angle with the tail plate main body 11, that is, the hinged seat 12 is arranged at an angle with the tail plate main body 11. A hinged hole 121 is formed in the hinged seat 12 in a transverse direction, a pin shaft (not labeled in the figure) is arranged in the hinged hole 121, and the driving end of the driving component 20 is matched with the pin shaft.

[0059] When the piston rod of the driving component 20 is extended, the driving component 20 pushes the pin shaft to drive the hinged seat 12 to move linearly, so that the tail plate body 11 rotates around the hinged point of the chassis 40, and the tail plate body 11 is switched from the hanging state to the inclined state.

[0060] When the piston rod of the driving component 20 is retracted, the driving component 20 pulls the pin shaft to drive the hinged seat 12 to move linearly, so that the tail plate body 11 rotates around the hinged point of the chassis 40, and the tail plate body 11 is switched from the inclined state to the hanging state.

[0061] The hooking part 323 is bent downward relative to the locking body 321, and a clamping groove 324 is limited between the hooking part 323 and the locking body 321, and the clamping groove 324 is clamped on the pin shaft when the locking piece 32 is in the locking state.

[0062] In order to ensure the stability of the locking piece 32, the height of the hooking part 323 is greater than the sum of the height of the locking body and the radius of the pin shaft. That is, the clamping groove 324 encircles the outside of the pin shaft, and the pin shaft cannot be pulled out of the clamping groove 324, thereby improving the reliability of the locking piece 32.

[0063] Continuing to refer to Figure 3 In some embodiments of the utility model, the side wall of the hinged seat 12 is welded with a limiting piece 13, the limiting piece 13 is internally structured with a limiting groove 131, and the pin shaft is arranged through the limiting groove 131.

[0064] When the locking piece 32 is in the locking state, the locking body 321 of the locking piece 32 and the clamping groove 324 formed by the hooking part 323 are clamped on the pin shaft, and the hooking part 323 is located in the limiting groove 131, and the left and right sides of the hooking part 323 of the locking piece 32 are limited by the groove walls of the limiting groove 131, thereby further improving the stability of the locking piece 32.

[0065] At this time, it can be understood that the freedom degrees of the front, rear, left and right directions of the locking piece 32 are all limited, and the reliability of the locking piece 32 is higher. That is, the freedom degree of the front and rear directions of the locking piece 32 is limited by the acting force of the driving component 20 and the hooking part 323 of the locking piece 32, and the freedom degree of the left and right directions of the locking piece 32 is limited by the two groove walls of the limiting groove 131.

[0066] Figure 5 is a partial structure schematic view two of the transport vehicle provided by the utility model embodiment. Figure 6 is Figure 5 is an enlarged view of the B part in

[0067] Referring to Figure 5 and Figure 6In some embodiments of the utility model, locking part 30 still includes linkage 33, locking piece 32 is symmetrically arranged at both sides of driving part 20, and both ends of linkage 33 are fixedly connected with each locking piece 32 respectively, and driving piece 31 is hinged with the middle position of linkage 33.

[0068] Equivalently, locking piece 32 is connected with driving piece 31 through linkage 33, and the piston rod of driving piece 31 is connected with linkage 33 through a pin shaft.

[0069] When driving piece 31 works to push linkage 33 to move upwards, linkage 33 drives two locking pieces 32 located at the left and right sides of driving part 20 to move synchronously, so that each locking piece 32 is switched from the locking state to the unlocking state.

[0070] When driving piece 31 works to push linkage 33 to retract, linkage 33 drives two locking pieces 32 located at the left and right sides of driving part 20 to move synchronously, so that each locking piece 32 is switched from the unlocking state to the locking state.

[0071] Equivalently, by arranging linkage 33, two locking pieces 32 located at the left and right sides of driving part 20 can be driven by the same driving piece 31, so that the manufacturing cost of locking part 30 is reduced.

[0072] In the above embodiment, in the case where linkage 33 is not arranged, each locking piece 32 can also be driven by an independent driving piece 31.

[0073] Continuing to refer to Figure 6 In some embodiments of the utility model, both ends of linkage 33 form fixed parts 331 connected with locking pieces 32 by bolts, screws and other fasteners, and each locking piece 32 is fixedly connected with the corresponding fixed part 331. The middle of linkage 33 is bent downward to form an avoiding part 332 for avoiding driving part 20, and driving piece 31 is hinged with avoiding part 332.

[0074] By arranging avoiding part 332, it can be prevented that linkage 33 interferes with driving part 20 when driving piece 31 drives linkage 33 to move, so as to affect the normal work of driving part 20.

[0075] Among them, avoiding part 332 includes connecting section 3321, first avoiding section 3322 and second avoiding section 3323, first avoiding section 3322 and second avoiding section 3323 are connected at the opposite ends of connecting section 3321, and an inverted trapezoidal avoiding groove 3324 is limited between connecting section 3321, first avoiding section 3322 and second avoiding section 3323.

[0076] The connecting section 3321, the first avoiding section 3322 and the second avoiding section 3323 can be formed by bending sheet metal, that is, the avoiding portion 332 and the fixing portion 331 are integrally formed.

[0077] In some embodiments of the utility model, in order to improve the structural strength of the linkage 33, the first avoiding section 3322 and the connecting section 3321, the second avoiding section 3323 and the connecting section 3321, the first avoiding section 3322 and the second avoiding section 3323 and the corresponding fixing portion 331 are all provided with reinforcing pieces 333.

[0078] For example, the first reinforcing piece is arranged between the first avoiding section 3322 and the connecting section 3321, the second reinforcing piece is arranged between the second avoiding section 3323 and the connecting section 3321, the third reinforcing piece is arranged between the first avoiding section 3322 and the corresponding fixing portion 331, and the fourth reinforcing piece 333 is arranged between the second avoiding section 3323 and the corresponding fixing portion 331.

[0081] When the tail plate main body 11 is in the hanging state, the tail plate main body 11 is equivalent to being lifted to the locking position, the tail plate main body 11 is away from the ground by a certain distance, the tail plate main body 11 is approximately parallel to the ground, the tail plate main body 11 serves as a load-carrying platform for the tracked fire-fighting robot transportation and carries the large weight of the tracked fire-fighting robot.

[0082] When the tail plate main body 11 is ready to fall, the driving part 20 needs to be retracted first, so that the pin shaft is away from the locking piece 32 by a certain gap, at this time, the driving piece 31 is controlled to be extended, so that the locking piece 32 is separated from the pin shaft to realize unlocking.

[0083] When the tail plate main body 11 is lifted to the hanging state, the driving piece 31 is retracted, and the locking piece 32 is lowered and locked.

[0084] The tail plate assembly provided by the embodiment of the utility model guarantees the tail plate body 11 to keep locking after lifting, realizes that the tail plate body 11 can keep in the lifting position, that is, the tail plate body 11 keeps the suspension position from descending through the locking part 30, the tail plate body 11 is not affected by the load, and the tail plate is not affected by the normal leakage of the hydraulic cylinder. The poor stability problem of the tail plate body 11 is fundamentally solved, the safety of the transport vehicle can be improved, and the transport vehicle transports the caterpillar type fire fighting robot.
