Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pipe transportation, and particularly relates to a transportation device for prestressed concrete cylinder pipes. Background Technique

[0002] A prestressed concrete cylinder pipe refers to a pipe made by winding circumferential prestressed steel wires on a high-strength concrete pipe core with a steel cylinder and then spraying a dense cement mortar protective layer thereon. After the prestressed concrete cylinder pipe is produced, it needs to be transported and transferred. The existing transfer method usually uses a hanging hook for hanging transportation. The lifting device is fixed on the wall of the steel cylinder concrete pipe, and then the concrete pipe is moved. In this transportation method, during the moving process, the stress at the hook is too large, which is easy to damage the concrete pipe, and the suspended movement is relatively dangerous, with potential safety hazards.

[0003] In view of the above problems, the invention with the patent publication number CN111907540A discloses a transportation device for concrete pipe production. The device includes a track, a transport vehicle, a second transport vehicle, and a concrete pipe. The transport vehicle is placed above the track, the second transport vehicle is arranged on one side of the transport vehicle, and the concrete pipe is placed above the transport vehicle. The track includes a guide rail and a cross bar. The guide rail is arranged in front of and behind the cross bar. The transport vehicle includes a bottom plate, a motor, load-bearing wheels, a motor bracket, rib plates, a lower connecting ear, an upper connecting ear, a pipe placing table, reinforcing ribs, anti-slip protrusions, and a connecting pin. The motor bracket is arranged below the bottom plate, the motor is arranged below the motor bracket, the load-bearing wheels are arranged in front of the motor, the rib plates are arranged on both sides of the motor, and the lower connecting ear is arranged on one side of the bottom plate.

[0004] The above invention can transport concrete pipes of different lengths, and the transportation process is stable, and the concrete pipes are not easily damaged by impact.

At the same time, the length of the prestressed concrete cylinder pipe is relatively long. When transporting, the prestressed concrete cylinder pipe lies on its side, occupying a large space, and the number of transported pipes is limited. Content of the Utility Model
