Automatic collecting device of thin-wall U-shaped steel pipe and collecting method

Abstract

An automatic collecting device of a thin-wall U-shaped steel pipe is characterized by comprising a chain feed device, a steel pipe bracket, an air cylinder oscillating device with a rolling support, an air cylinder and a synchronous shaft, a webbing sling collecting device with a webbing sling, a driving motor, a driving shaft and a winding drum and an adjusting device consisting of a manual screw rod, a screw with thread and a hand wheel. The automatic thin-wall U-shaped steel pipe collecting method is characterized by: after taking materials through the chain, using the rolling support for delivering the U-shaped steel pipe to an L-shaped hook of the chain so that the chain completely detaches from the steel pipe; then supporting the U-shaped steel pipe by the rolling support to realize the feed of the steel pipe; subsequently causing the air cylinder to act so that the synchronous shaft drives the rolling support to swing; and putting the U-shaped steel pipe on the webbing sling and then starting the motor and using the driving shaft and the winding drum to descend the U-shaped steel pipe on the webbing sling to a certain height, thus realizing the stacked collection of U-shaped steel pipes. The method and the device achieve the effect of meeting the requirement for collecting large-size U-shaped thin-wall steel pipe during the processes of hoisting, storing, packaging and transporting.

Description

Technical field: [0001] The invention relates to a steel pipe production auxiliary equipment, in particular to an automatic collection device and a collection method for thin-walled U-shaped steel pipes in nuclear power equipment, boilers and pressure vessels. Background technique: [0002] Most of the existing steel pipes are collected by means of collection frames. During the collection of steel pipes, steel pipes often collide with each other to generate noise and deformation of the steel pipes, seriously affecting the health of the operator and the quality of the steel pipes. The 200820027753.1 patent improves the collection device used in the above-mentioned steel pipe collection method, and provides a steel pipe collection device (such as Figure 8 shown) includes rocker arm, pull rope, trolley, guide rail, steel wire rope, support frame, base, cylinder and other components. Under the action of cylinder, steel wire rope and trolley, the device produces buffer and reduce...

Problems solved by technology

[0002] Most of the existing steel pipe collection is realized by the collection frame method. During the steel pipe collection process, steel pipes often collide with each other to generate noise and deformation of the steel pipe, which seriously affects the health of the operator and the quality of the steel pipe.

The 200820027753.1 patent improves the collection device used in the above-mentioned steel pipe collection method, and provides a steel pipe collection device (such as Figure 8 shown) includes rocker arm, pull rope, trolley, guide rail, steel wire rope, support frame, base, cylinder and other components. Under the action of cylinder, steel wire rope and trolley, the device produces buffer and reduces the noise generated during the collection of steel pipes. However, the deformation of steel pipes caused by mutual impact and thus affecting the quality of steel pipes still exists.

For small-diameter, thin-walled, large-size U-shaped pipe fittings, in the process of lifting, storage, packaging, transportation and assembly, mutual friction and collision between the pipe fittings and any items harmful to the quality of the pipe fittings are not allowed, manual handling, stacking Stacking not only has low production efficiency and high cost, but it is also difficult to overcome the deformation of steel pipes during the process of handling and stacking. At present, there is no special steel pipe collection and storage device for U-shaped thin-walled steel pipes.
