Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing line technology, and in particular to a waste pipe grounding structure on a steel pipe processing line. Background Technology

[0002] Steel pipe is a tubular material made of steel, commonly used as a pipeline for transporting fluids such as oil, natural gas, water, and coal gas. The production of steel pipes requires multiple processes such as cold drawing, cold rolling, and hot rolling. In the steel pipe processing line, conveyor rollers are usually used to transfer steel pipes between processes. After completing a designated process, the steel pipes are inspected to ensure that the quality of the steel pipes meets the requirements. Among them, the unqualified scrap pipes need to be transferred out of the steel pipe processing line to prevent them from entering the next process.

[0003] When waste pipes are detected, existing steel pipe processing lines require a crane to lift the waste pipes off the roller conveyor, which seriously affects the processing efficiency of the steel pipe processing line. There is a lack of a structure that can transfer waste pipes from the conveyor roller conveyor or transfer them to another roller conveyor via a transfer structure for ground output, so that the waste pipes can be lifted off the ground by a crane, thus not affecting the processing efficiency of the steel pipe processing line. Utility Model Content

The roller conveyor forms a pipe dropping station and a grounding side located on one side of the pipe dropping station for waste pipes to be dropped. The several sets of pipe dropping modules are arranged at intervals between the pipe dropping stations.

[0007] Each pipe dropping module includes a fixed seat, a fulcrum shaft, a pipe lifting swing arm, a pipe dropping swing arm, a pipe dropping driving cylinder and two traction rods; the fulcrum shaft is arranged on the pipe dropping side in the same direction as the conveying direction of the roller path, and one end of it is rotatably mounted under the top of the roller path through the fixed seat; both the pipe lifting swing arm and the pipe dropping swing arm are mounted at the other end of the fulcrum shaft at one end thereof, and can swing with the fulcrum shaft as the rotation fulcrum. The other end of the pipe lifting swing arm extends towards the direction where the roller path is located and forms a pipe supporting guiding edge that can rise and fall relative to the top of the roller path with the swing; the other end of the pipe dropping swing arm extends towards the pipe dropping direction and forms a pipe dropping guiding edge that can rise and fall relative to the ground with the swing; the pipe dropping driving cylinder is obliquely arranged on the other side of the roller path, and the telescopic rod of the pipe dropping driving cylinder is arranged towards the fulcrum shaft. The bottom ends of the two traction rods are hinged to the telescopic rod of the pipe dropping driving cylinder, the top end of one traction rod is hinged to the middle section of the pipe lifting swing arm, and the top end of the other traction rod is hinged to the middle section of the pipe dropping swing arm, so that the telescopic rod of the pipe dropping driving cylinder can extend and retract to drive the pipe lifting swing arm and the pipe dropping swing arm to swing by the two traction rods.

[0008] As a further technical solution of the present utility model: when the telescopic rod of the pipe dropping driving cylinder extends, the pipe lifting swing arm swings from below the top of the roller path to above, and the waste pipe is lifted from the roller path by the pipe supporting guiding edge. The pipe dropping swing arm swings from a position near the ground to above the ground, and the waste pipe transitions along the pipe supporting guiding edge to the pipe dropping guiding edge. As the telescopic rod of the pipe dropping driving cylinder retracts, the pipe lifting swing arm and the pipe dropping swing arm are reset, and the waste pipe is taken to the ground by the pipe dropping guiding edge.

[0009] As a further technical solution of the present utility model: the roller path includes a number of conveying roller seats arranged at intervals. Each conveying roller seat includes a seat body and a roller body rotatably mounted on the top of the seat body, and a driving motor for driving the roller body to rotate is provided on some of the conveying roller seats.

[0010] As a further technical solution of the present utility model: the roller body is in an hourglass shape, and a groove for limiting the steel pipe is formed in the middle thereof.

[0011] As a further technical solution of the present utility model: the fixed seat is mounted on the seat body of the conveying roller seat at the pipe dropping station.

[0012] As a further technical solution of the present utility model: the pipe dropping guiding edge forms a bottom edge section adjacent to the fulcrum shaft and a baffle edge section far from the fulcrum shaft, and the included angle between the bottom edge section and the baffle edge section is an obtuse angle.

[0013] As a further technical solution of the present utility model: the pipe dropping guiding edge is in a shape of '丿' formed by connecting multiple straight edges end to end.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model proposes a waste pipe grounding structure on a steel pipe processing line. Through the cooperation between several sets of pipe dropping modules, the waste pipe is lifted from the roller conveyor by the pipe lifting swing arm and the pipe dropping swing arm under the swing of the pipe lifting swing arm. After the waste pipe transitions from the pipe lifting swing arm to the pipe dropping swing arm, the waste pipe is brought to the ground by the pipe dropping swing arm, realizing the grounding and output of the waste pipe. This allows the waste pipe to be lifted away by a crane on the ground without affecting the processing efficiency of the steel pipe processing line. Attached Figure Description

The bottom ends of the two traction rods 26 are hinged to the telescopic rod of the pipe-dropping drive cylinder 25, the top end of one traction rod 26 is hinged to the middle section of the pipe-lifting swing arm 23, and the top end of the other traction rod 26 is hinged to the middle section of the pipe-dropping swing arm 24, so that the telescopic rod of the pipe-dropping drive cylinder 25 can extend and retract, and the two traction rods 26 provide the driving force for the swing of the pipe-lifting swing arm 23 and the pipe-dropping swing arm 24.

[0022] Specifically, the telescopic rod of the pipe-dropping drive cylinder 25 extends, the pipe-lifting swing arm 23 swings from below the top of the roller conveyor 10 to the top, and the waste pipe is lifted from the roller conveyor 10 by the support guide edge 231. The pipe-dropping swing arm 24 swings from a position near the ground to above the ground, and the waste pipe transitions along the support guide edge 231 to the pipe-dropping guide edge 241. As the telescopic rod of the pipe-dropping drive cylinder 25 retracts, the pipe-lifting swing arm 23 and the pipe-dropping swing arm 24 reset, and the waste pipe is brought to the ground by the pipe-dropping guide edge 241.

[0023] Furthermore, in this embodiment, the roller conveyor 10 includes a plurality of conveyor roller seats 11 spaced apart.
