Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe collecting equipment, and in particular relates to a device for collecting steel pipes based on a single station. Background Art

[0002] At present, seamless steel pipes produced by continuous pipe rolling need to be inspected for surface quality and measured for geometric dimensions. The surface quality inspection items usually include whether there are defects such as cracks, folds, rolling, delamination and scarring on the inner and outer surfaces of the steel pipes. The geometric dimension measurement items usually include the outer diameter, wall thickness, length, straightness and out-of-roundness of the steel pipe. In order to improve the efficiency of detection, multiple steel pipes are usually laid flat on the collection stand. In order to facilitate the rolling of steel pipes, two to three spaces are usually reserved on the collection stand. Some pipe-making companies have successively developed steel pipe collection devices, which usually collect and package multiple steel pipes uniformly first, and then hoist the whole bundle of steel pipes onto the inspection stand for unpacking and laying, which invisibly increases the workload, which will not only increase the production cost of steel pipes, but also reduce the production efficiency of steel pipes.

[0003] After searching, it was found that three literature patents are most relevant to the utility model technology, and the specific contents are described as follows:

[0004] Patent document CN 200520041259.7 discloses a low-noise steel pipe collection device, which mainly includes an inclined stand, a steel wire rope, a pulley, a collection frame, a counterweight, a protective cover, a spring and a limit block. Since the device uses a counterweight, a steel wire rope and a pulley in combination, the device can achieve a slow descent of the steel wire rope so as to achieve flexible collection of the steel pipe and reduce noise. However, the device collects the steel pipes in a stacking manner, with the aim of packaging the steel pipes rather than directly conducting centralized inspections.

[0005] Patent document CN 201520395966.X discloses an online steel pipe collection device, which mainly includes a baffle, a lower slide plate, a bottom plate, a pad, a slide rail, a liner, a sliding car, a collection trough, a connecting plate and a pulley fixing plate. Since the device can adjust the size of the collection trough by driving the movement of the baffle plate by the sliding car, the device can adapt to the packaging requirements of different quantities of steel pipes. However, the device collects steel pipes in a stacking manner, with the purpose of packaging the steel pipes rather than directly conducting centralized inspection.

[0006] Patent document CN 202021566623.2 discloses a steel pipe collection device, which mainly includes an inclined stand, a material receiving trough, a rotating shaft, a connecting part, a sling, wheels, a noise reduction belt, a motor, a bracket, a copper sleeve, a pressure plate, a buffer arm, a material blocking arm, a connecting arm and a cylinder. Since the device can avoid collisions between steel pipes, the device can achieve flexible collection of steel pipes and reduce noise. However, the device collects steel pipes in a stacking manner, with the aim of packaging the steel pipes rather than directly conducting centralized inspections. Utility Model Content
