The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the working order. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

Please refer to Figure 1-3, a transport device for bridge construction;

During bridge construction, in the material transportation work, in order to solve the problem of inconvenience in manually adjusting the volume change of the material storage box, and the problem that the operator needs to exert force to pull the transportation device under the influence of gravity when going downhill, a storage and transportation structure is set on the fixed half box 2, and the technical solution is as follows;

Specifically, the device components include two support rods 1, a fixed half box 2 and a storage and conveying structure;

More specifically, the storage and conveying structure includes a connecting plate 3 and an adjusting half box 4. The connecting plate 3 is a U-shaped structure. The connecting plate 3 is installed at one end of the fixed half box 2. A U-shaped groove 5 is opened on the adjusting half box 4. The adjusting half box 4 is movably installed at one end of the connecting plate 3 through the U-shaped groove 5; an adjusting cylinder 6 is installed on the outer wall of the fixed half box 2, and the telescopic end of the adjusting cylinder 6 is installed on the outer wall of the adjusting half box 4; the lower wall of the fixed half box 2 and the adjusting half box 4 are both installed with a movable structure;

It should be noted that when in use, the operator holds two support rods 1, and the control device moves through the mobile structure. The materials to be transported are placed in the space composed of the fixed half box 2, the connecting plate 3, and the adjusting half box 4. When the size of the space needs to be adjusted, the adjusting cylinder 6 is controlled to extend and retract, so that the adjusting half box 4 moves on the connecting plate 3 through the U-shaped groove 5. The operator does not need to manually push and pull the adjusting half box 4, and only needs to control the adjusting cylinder 6 to work, which is convenient to use.

It should be noted that when the device moves, the roller 12 drives the rotating shaft 8 to rotate on the support frame 7. When the device moves downhill on the bridge deck, the user can control the clamping cylinder 10 on the support frame 7 to extend, so that the fixed friction disc 11 contacts the rotating friction disc 9. Under the action of friction, the rotation speed of the rotating friction disc 9 is reduced, so that the rotation speed of the rotating shaft 8 and the roller 12 is controlled when going downhill, and the device is prevented from moving too fast when going downhill, which increases the safety factor. There is no need for the operator to apply force to pull the device, which is convenient to use.
