[0057] Optionally, the electrical box 8 includes a battery, a motor and a current controller; the battery is electrically connected to the motor through the current controller, and the output shaft of the motor is connected to the gear set 9; the starting mechanism is connected to the current controller. Specifically, the electrical box 8 is installed at the bottom of the frame 1, and the battery and the current controller are installed inside the electrical box 8. The gear set 9 is installed in the middle of the axle 10, and the axle 10 is connected to the tire through the supports 15 on both sides of the frame 1.

[0058] In this embodiment of the utility model, the brake mechanism includes a brake disc 12 and a brake caliper 13; the brake disc 12 is fixedly arranged on the wheel 7, and the brake caliper 13 can be movably matched with the brake disc 12; the brake caliper 13 is configured to clamp the brake disc 12 to stop the wheel 7 from rotating, or to move away from the brake disc 12 to allow the wheel 7 to rotate freely.

[0063] See also Figure 4 and Figure 5As can be seen from the figure, in this embodiment of the utility model, the anti-slip iron plate 11 includes an iron plate layer 100, a buffer layer 200 and a wear-resistant layer 300 connected in sequence; the iron plate layer 100 is close to the frame 1, and the wear-resistant layer 300 is located on the side away from the frame 1; a guide column 110 is provided on the iron plate layer 100, and the buffer layer 200 and the wear-resistant layer 300 are provided with corresponding guide holes 410, and the guide column 110 can sequentially penetrate the guide holes 410 of the buffer layer 200 and the wear-resistant layer 300; the iron plate layer 100, the buffer layer 200 and the wear-resistant layer 300 are all provided with corresponding mounting holes 430; the fastener 500 is fastened in the mounting hole 430 of the iron plate layer 100 after sequentially penetrating the mounting holes 430 of the wear-resistant layer 300 and the buffer layer 200.

[0064] Optionally, the wear-resistant layer 300 is made of high-hardness ABS plastic, and the wear-resistant layer 300 is detachable to ensure that the anti-skid iron plate 11 has a long service life. Furthermore, the top surface frame of the wear-resistant layer 300 has a plurality of anti-skid grooves (not shown in the drawings) to ensure the anti-skid effect. The buffer layer 200 is a rubber layer, which buffers the force on the wear-resistant layer 300 and applies it to the iron plate layer 100 to reduce the vibration of the vehicle body, so as to protect the vehicle body and the anti-skid iron plate 11. The iron plate layer 100 is a whole steel plate, which can not only serve as a support for the frame 1, but also ensure the overall stability and reliability of the anti-skid iron plate 11.

[0065] Optionally, the fastener 500 is threadedly connected to the mounting hole 430. Further, the fastener 500 is a round head screw.

[0066] It can also be seen from the figure that in this embodiment of the utility model, a sealing cover 111 is provided on the top of the guide column 110 to seal the top opening of the guide hole 410 of the wear-resistant layer 300; the top of the mounting hole 430 of the wear-resistant layer 300 has a step portion 431, and the head of the fastener 500 can be embedded in the step portion 431, so that the top of the fastener 500 is flush with the surface of the wear-resistant layer 300. In this way, the flatness of the surface of the wear-resistant layer is guaranteed, and the fastener 500 and the guide column 110 can be stably arranged.

[0067] from Figure 5 It can also be seen that in this embodiment of the utility model, a plurality of anti-sliding blocks 333 are arranged on the surface of the wear-resistant layer 300; along the length direction of the frame 1, the number of anti-sliding blocks 333 gradually increases from the direction away from the left handle 4 to the direction close to the left handle 4. That is, more anti-sliding blocks 333 are arranged on the side of the vehicle body close to the left and right push rods 3, so as to ensure that the cut pieces are not easy to fall out of the vehicle body from the left and right push rods 3.

[0068] Optionally, the anti-sliding block 333 is triangular, and the bottom edge of the anti-sliding block 333 faces the direction of the left and right push rods 3. Because the end of the frame 1 facing the left and right push rods 3 is open, when the block moves from the side away from the left and right push rods 3 to the side close to the left and right push rods 3, it will be subject to greater friction damping, thereby ensuring that the block on the body is not easy to fall from the open mouth.

[0069] In summary, the embodiment of the utility model provides an electric flatbed cart for transporting building blocks on a construction site, which has at least the following advantages:

[0070] The purpose of this solution is to overcome the shortcomings of the existing technology and provide an electric flatbed cart structure. The structure changes the traditional manual push-pull structure of the cart into an electric-assisted push-pull structure, which can reduce the user's workload, reduce transportation time, improve work efficiency, and solve the problem of difficulty in transporting building blocks due to uneven ground on construction sites.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
