Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and more specifically, to a large plaza brick transport vehicle. Background Technology
[0002] During the construction of road and plaza paving bricks, the bricks usually need to be manually transported to the work surface. Commonly used paving bricks are made of firebricks or ordinary red bricks cut into blocks by a cutting machine. They are relatively small in size and lightweight, making the process of transporting them relatively effortless. However, for some large plazas, the paving bricks used are large in volume and heavy in weight, making manual transport time-consuming and laborious.
[0003] Therefore, in order to address this problem, we urgently need to develop a special handling equipment for large-sized bricks to reduce the workload of construction workers and improve the efficiency of brick laying. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, a large plaza brick transport vehicle that is easy to move is provided.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

Detailed Implementation
[0024] 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.
[0025] like Figures 1 to 5 As shown, a large plaza brick transport vehicle includes a trolley support 1, a front clamp 2, a rear clamp 3, and a control lever 4. The upper end of the trolley support 1 has a U-shaped structure. Two L-shaped front clamps 2 are provided, with their horizontal sections slidably inserted on both sides of the trolley support 1. The bent sections of the front clamps 2 are vertically downwards, forming clamping ends 21. To accommodate bricks of different sizes, a length adjustment mechanism 5 is provided between the front clamps 2 and the trolley support 1. Specifically, the length adjustment mechanism 5 includes an adjusting screw 51 and a fixing nut 52. The adjusting screw 51 is rotatably mounted in the straight tubes on both sides of the trolley support 1, and the fixing nut 52 is fixedly mounted in the front clamp 2. The fixing nut 52 is threadedly connected to the adjusting screw 51 on the corresponding side. By rotating the adjusting screw 51, the relative position of the front clamp 2 and the trolley support 1 can be adjusted.
[0026] The rear clamp 3 adopts a U-shaped plate structure and is slidably mounted on the trolley bracket 1. A positioning shaft 11 is provided at the rear end of the trolley bracket 1. A positioning sleeve 41 that rotatably engages with the positioning shaft 11 is fixedly provided at the lower middle part of the control lever 4, allowing the control lever 4 to rotate relative to the positioning shaft 11. A hinge shaft I 42 is provided on the control lever 4, located at the lower end of the positioning sleeve 41. A hinge shaft II 31 is provided on the rear side of the rear clamp 3. A connecting rod 32 is hinged between the hinge shaft I 42 and the hinge shaft II 31. When the control lever 4 rotates, the connecting rod 32 pushes the rear structure 3 to move closer to or away from the front clamp 2, thereby tightening or loosening the plaza bricks.
[0027] The rear end of the trolley support 1 is provided with a pivot 12, and trolley wheels 13 are provided on both sides of the pivot 12 to facilitate the movement of the transport vehicle.
[0028] To prevent plaza bricks from falling during transport and improve the success rate of transfer, based on Embodiment 1, a mounting frame 22 is fixedly installed between the two front clamps 2. A control plate 23 is slidably installed inside the mounting frame 22, and a spring 24 is installed between the control plate 23 and the mounting frame 22. A flip plate 6 is rotatably installed at the lower end of the mounting frame 22, and an insert plate I 61 is vertically installed at the front end of the flip plate 6. When the flip plate 6 rotates downward, it drives the insert plate I 61 to insert under the brick, thereby limiting the brick. To achieve the flipping of the flip plate 6, a hinge hole I 62 is provided on the flip plate 6, a hinge hole II 63 is provided on the mounting frame 22, and a hinge hole III 64 is provided on the control plate 23. Hinges I 62, hinge holes II 63, and hinge holes III 64 are respectively connected to hinge rods 65 and hinged to one end of each. The other ends of the three hinge rods 65 are hinged to each other. When the flip plate 6 is in a horizontal state, the included angle between adjacent hinge rods 65 is less than 180°.
[0029] When clamping a brick, the control plate 23 compresses the spring 24 and moves towards the mounting bracket 22. This, in turn, pushes the other two hinge rods to rotate through the hinge rod connected to the hinge hole Ⅲ 64, thereby pushing the tilting plate from a horizontal state to a vertical state. A limit structure 25 is provided between the tilting plate 6 and the mounting bracket 22 to limit the tilting stroke of the tilting plate 6 from a horizontal state to a vertically downward state. An auxiliary wheel 66 is rotatably provided at the front end of the tilting plate 6, which can cooperate with the trolley wheel 13 to achieve movement.
[0030] When the brick is released, the spring 24 pushes the control plate 23 to move in the opposite direction, which in turn drives the flip plate 6 to rotate from the vertical downward state to the horizontal state through the three hinge rods.
[0031] Preferably, an insert plate II 33 can be provided on the lower side of the rear clamp 3. The insert plate II 33 is slidably connected to the trolley bracket 1. A hinge shaft III 43 is provided at the lower end of the control lever 4. The distance between the hinge shaft III 43 and the positioning sleeve 41 is greater than the distance between the hinge shaft II 31 and the positioning sleeve 41. A drive rod 34 is provided between the rear side of the insert plate II 33 and the hinge shaft III 43. The two ends of the drive rod 34 are hinged to the insert plate II 33 and the hinge shaft III 43, respectively. When the control lever 4 rotates, it simultaneously drives the rear clamp 3 and the insert plate II 33 to move. Since the distance between the hinge shaft III 43 and the positioning sleeve 41 is greater than the distance between the hinge shaft II 31 and the positioning sleeve 41, the stroke of the insert plate II 33 is greater than the stroke of the rear clamp 3, which facilitates the insertion of the insert plate II 33 under the brick.
[0032] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
