Description

Technical Field

[0001] This utility model relates to a pipeline conveying device, and more particularly to a pipeline conveying trolley suitable for multi-span integrated production lines. Background Technology

[0002] The existing steel pipe production line is a multi-span integrated production line, from steel coils to formed pipes. The steel pipe production process involves crossing the spans of the factory building with supporting columns spaced 7.5m apart. While ensuring the structural stability and safety of the factory building, at most one column can be removed. However, the 18m length of the steel pipe is still too long to allow for transfer between two spans. The existing steel pipe conveyor rollers are usually fixed to the ground, making horizontal crossing of the steel pipes impossible. If they have an excessively large inclination angle, they will occupy unused space. Furthermore, with limited space at the crossing points, it is impossible to transfer the steel pipes to adjacent conveyor rollers. Utility Model Content

[0005] A transport and management trolley suitable for multi-span integrated production lines is characterized in that the device includes a trolley body and a steel pipe conveying mechanism, wherein the steel pipe conveying mechanism is mounted on the trolley body via a rotating mechanism.

[0006] The steel pipe conveying mechanism includes a crossbeam and several conveying rollers arranged side by side along the axis of the steel pipe. Each conveying roller is mounted on the crossbeam via a lifting mechanism. A conveying motor for driving the conveying roller is mounted on the lifting mechanism. The conveying motor is a motor that can rotate in both forward and reverse directions; it conveys the steel pipe forward in forward rotation and reverses it backward.

[0007] The rotating mechanism includes a rotating seat at one end of the crossbeam and a guide mechanism at the other end of the crossbeam. One end of the crossbeam is fixed on the rotating seat, the rotating seat is mounted on the vehicle body, the other end of the crossbeam is slidably connected to the guide mechanism, and the middle part of the crossbeam is hinged to the drive cylinder mounted on the vehicle body.

[0008] The guiding mechanism includes an arc-shaped guide rail arranged along the rotation direction of the crossbeam and rollers that cooperate with the arc-shaped guide rail. The rollers are installed at the bottom of the crossbeam.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the vehicle body includes a frame and a traveling wheel installed at the bottom of the frame, and a traveling motor for driving the traveling wheel is installed on the frame.
