[0030] The purpose of the utility model is to provide a push plate trolley, a push plate trolley assembly and a transport vehicle to solve the problems existing in the above-mentioned prior art, and to better push materials forward and prevent materials from moving up and falling into the vehicle box at the rear side.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] Example 1

[0033] like Figure 1-Figure 2 As shown, in this embodiment, a push plate trolley 100 is provided, which mainly includes a frame body 101. A pushing surface 102 is provided on the side of the frame body 101 close to the rear end of the transport vehicle, and the pushing surface 102 is an arc-shaped surface; specifically, the longitudinal section of the pushing surface 102 is an arc-shaped; it should be noted that, in this embodiment, the "longitudinal section" refers to the section formed by cutting from top to bottom.

[0034] In this embodiment, the pushing surface 102 of the push plate trolley 100 is an arc-shaped surface with an arc-shaped longitudinal section. Compared with the existing inclined plane, it can better push the material forward (push the material from the front to the rear of the vehicle) and prevent the material from moving up and falling into the vehicle box on the rear side of the push plate trolley 100 (close to the front of the vehicle).

[0035] In this embodiment, side panels 103 are provided on both the left and right sides of the push surface 102 to block the material. It should be noted that in this embodiment, the "left and right sides" refer to the left and right sides when facing the push surface 102. Furthermore, a sealing blade is provided on each side of the side panel 103 away from the vehicle frame body 101. The sealing blade is rotatably connected to the corresponding side panel 103 via a hinge, allowing the sealing blade to rotate forward and backward. The side of the sealing blade away from the side panel 103 can be in contact with the side wall of the vehicle box, providing a seal during unloading to prevent material from moving backward.

[0036] Furthermore, it should be noted that the width of the frame body 101 plus the sealing blades on both sides in this embodiment is greater than the maximum width of the vehicle body, which can limit the backward rotation angle of the sealing blades to prevent the sealing blades from rotating excessively and causing the material to move backward (toward the front of the vehicle).

[0037] In this embodiment, the hinged part can be selected according to specific work needs, and is preferably a hinge.

[0038] In this embodiment, clamping devices 104 are provided on both sides of the frame body 101. The clamping devices 104 are used to clamp with the vehicle box. When unloading, they can clamp the vehicle box to fix the push plate trolley 100 and prevent the push plate trolley 100 from moving backward.

[0039] In this embodiment, if Figure 6 As shown, the clamping device 104 mainly includes a clamping plate 1044, a clamping arm 1043 and a progressive oil cylinder 1041. The clamping plate 1044 is used to fit with the car box, and the side of the clamping plate 1044 away from the car box is connected to the clamping arm 1043, the clamping arm 1043 is perpendicular to the clamping plate 1044, and the end of the clamping arm 1043 away from the clamping plate 1044 is connected to the progressive oil cylinder 1041, and the progressive oil cylinder 1041 can drive the clamping arm 1043 and the clamping plate 1044 moves along the length direction of the clamping arm 1043 to clamp the car body; a clamping slide 1042 is also provided at the bottom of the frame body 101 in a direction perpendicular to the clamping plate 1044, and the clamping arm 1043 is slidably set in the clamping slide 1042 to guide the movement of the clamping arm 1043; the progressive cylinder 1041 is extended and retracted to make the clamping arm 1043 slide in the clamping slide 1042, driving the clamping plate 1044 to extend and retract, so that it is clamped to the car body, thereby fixing the push plate trolley 100.

[0040] Furthermore, the progressive oil cylinder 1041 is also connected to an oil pipe for oil supply, and the oil pipe is wrapped in an oil pipe bracket 300, and the oil pipe is protected by the oil pipe bracket 300; wherein, Figure 7As shown, the oil pipe bracket 300 is provided with multiple sections, and the multiple sections of the oil pipe bracket 300 are connected end to end in sequence and spread out on the sliding base plate 200; both ends of any oil pipe bracket 300 are provided with connecting ear plates 302, and the connecting ear plates 302 at the connection of two adjacent sections of the oil pipe bracket 300 are rotatably connected by a pin shaft, thereby realizing the folding and extension of the multiple sections of the oil pipe bracket 300; the front end of the first section of the oil pipe bracket 300 is rotatably connected to the bottom of the frame body 101 through the bracket seat 301, and the rear end of the last section of the oil pipe bracket 300 is rotatably connected to the side of the vehicle box close to the front of the vehicle box through the bracket seat 301, and the length of the first section and the last section of the oil pipe bracket 300 is relatively short, which is convenient for connection with the frame body 101 and the middle part of the front side of the vehicle box.

[0041] In this embodiment, the tubing support 300 is hollow, and the tubing is wrapped inside to protect the tubing. Moreover, the tubing support 300 is telescopic and foldable, so that the tubing can follow the changes and achieve the effect of directional movement and extension. Compared with the related art in which the tubing is directly exposed to the outside, the tubing support 300 is spread on the sliding base plate 200, which can effectively prevent the tubing from being worn, squeezed, broken, etc.

[0042] In this embodiment, a positioning assembly is further provided at the top of the vehicle frame body 101 for positioning with a positioning beam on the side wall of the vehicle box, and a positioning slider 107 is further provided at the bottom of the vehicle frame body 101 for fixed connection with the sliding base plate 200. Specifically, the positioning assembly is preferably a positioning wheel assembly. The top of the vehicle frame body 101 is a rectangular structure, and a positioning wheel assembly is provided at each of the four corners of the top of the vehicle frame body 101.

[0043] In this embodiment, by providing a positioning wheel assembly, the push plate trolley 100 can be prevented from tilting forward and backward when moving.

[0044] The utility model also provides a push plate trolley assembly, such as Figure 3 As shown, it includes a sliding base plate 200 and the above-mentioned push plate trolley 100, and the push plate trolley 100 is arranged on the sliding base plate 200.

[0045] like Figure 4 and Figure 5As shown, in this embodiment, limiting structures are provided on both sides of the sliding base plate 200 to form a parallel track on the sliding base plate 200, and the push plate trolley 100 is set on the parallel track; compared with the pure flat base plate with a narrow front and a wide back in the prior art, the push plate trolley 100 can be better limited to prevent it from tilting when moving forward and backward.

[0046] In this embodiment, if Figure 5 As shown, the limiting structure is preferably a bent structure 201. Specifically, the two sides of the sliding base plate 200 are bent to form a parallel track with equal widths at the front and back, while the upper edge remains narrower at the front and wider at the back. Furthermore, the bent sliding base plate 200 provides increased strength. It should be noted that the limiting structure is not limited to the aforementioned bent structure 201. Other limiting structures may be selected based on operational needs, such as providing limiting bosses on both sides of the sliding base plate 200.

[0047] This embodiment also provides a transport vehicle, including the push-plate trolley 100 or the push-plate trolley assembly as described above.
