Specific implementation mode

[0021] As Figures 1 to 4 shown, an embodiment of the present utility model provides a building engineering material transfer vehicle, which includes a bottom plate 1. Universal wheels 2 are provided at the four corners of the bottom plate 1. A push frame 11 is installed outside the bottom plate 1. A carrying box 5 is provided on the top of the bottom plate 1. An opening and closing assembly is provided outside the carrying box 5. A lifting assembly is provided inside the carrying box 5. The lifting assembly includes a lead screw 22 movably sleeved inside the carrying box 5. The lead screw 22 penetrates through one side of the carrying box 5 and a motor one 14 is installed outside. A moving seat one 23 is threadedly sleeved on the outside of the lead screw 22. A connecting rod one 19 is fixedly connected to the outside of the moving seat one 23. Two connecting plates 18 are rotatably connected to the ends of the connecting rod one 19. A connecting rod two 25 is rotatably connected between the two connecting plates 18. A connecting block one 26 is fixedly connected to the center of the connecting rod two 25. A carrying plate 17 is fixed to the top of the connecting block one 26.

[0022] As Figure 1 and Figure 3 shown, the opening and closing assembly includes two slide rails 8 fixedly installed outside the carrying box 5. A carrying cover plate 7 is slidably sleeved inside the two slide rails 8. Two mounting blocks 9 are provided outside the carrying box 5. A screw 13 is movably sleeved between the two mounting blocks 9. The screw 13 penetrates through one side of the mounting block 9 and a motor two 10 is installed outside. A moving seat two 12 is threadedly sleeved on the outside of the screw 13. A connecting seat 15 is installed on the top of the moving seat two 12. A connecting block two 16 is installed on the top of the connecting seat 15. The outside of the connecting block two 16 is fixedly connected to the carrying cover plate 7. The connecting seat 15 on the top of the moving seat two 12 drives the carrying cover plate 7 to move synchronously to the right through the connecting block two 16, thereby clamping the carrying cover plate 7 on the top of the carrying box 5 to prevent the materials from falling out of the vehicle when they are too full.

[0023] As Figure 2 and Figure 4 shown, a plurality of damping springs 24 are installed on the top of the carrying plate 17. A support plate 6 is installed on the top of the damping springs 24. When the materials placed on the top of the support plate 6 are vibrated, the damping springs 24 can play a role in damping vibration and prevent the materials from colliding with each other.

[0024] As Figure 1 and Figure 2 as well as Figure 4 As shown, a limiting rod 4 is installed inside the carrying box 5, and a limiting groove 27 is opened on the outer side of the carrying plate 17 close to the limiting rod 4. The limiting groove 27 is slidably connected with the limiting rod 4 to increase the stability when the support plate 6 moves. A guiding groove 21 is opened inside the carrying box 5, and a guiding block 20 is installed at the bottom of the first moving seat 23. The guiding block 20 is slidably connected with the guiding groove 21 to increase the stability when the first moving seat 23 moves.

[0025] As Figure 1 and Figure 2 as well as Figure 3 As shown, a battery pack 3 is installed outside the carrying box 5. The battery pack 3 is electrically connected to the first motor 14 and the second motor 10 to supply power to drive the first motor 14 and the second motor 10.

[0026] Working principle:

[0027] Before use, the material to be transported needs to be placed on the top of the support plate 6, and then the second motor 10 is started, so that the output shaft of the second motor 10 drives the screw rod 13 to rotate. Then, during the rotation, the second moving seat 12 outside the screw rod 13 moves to the right. At this time, the connecting seat 15 on the top of the second moving seat 12 drives the carrying cover plate 7 to move to the right synchronously through the second connecting block 16, and then the carrying cover plate 7 is clamped on the top of the carrying box 5 to prevent the material from falling out of the vehicle easily when it is overloaded. At this time, the second motor 10 stops rotating, and then the device can be moved by the universal wheels 2 at the bottom of the bottom plate 1. When the device reaches the place where unloading is required, the first motor 14 is started, so that the output shaft of the first motor 14 drives the lead screw 22 to rotate. Then, the first moving seat 23 outside the lead screw 22 moves to the left. Then, during the movement, the connecting plate 18 rotatably connected through the first connecting rod 19 drives the second connecting rod 25 to move upward. Then, during the movement, the carrying plate 17 is synchronously driven to move upward through the first connecting block 26, so that the material placed on the support plate 6 moves upward, which is convenient for manual handling of the material.
