Operation method of steel pipe hydraulic-type lifting blanking device

Abstract

The invention relates to an operation method of a steel pipe hydraulic-type lifting blanking device. A base is adjusted to be parallel to the horizontal plane through anchor screws, meanwhile the height of the base is adjusted through the anchor screws, the included angle between a long arm and a short arm is adjusted according to the diameter of a steep pipe, and a piston rod on a hydraulic cylinder drives a lifting arm to rotate around a hinge pin at the upper end of the lifting arm; the piston rod on the hydraulic cylinder drives the lifting arm to descend, accordingly, the lifting arm is adjusted to be at a proper height, and the steel pipe slowly rolls to the bending portion of the lifting arm along the short arm from a rack; after the steep pipe is stably stopped, the piston rod on the hydraulic cylinder drives the lifting arm to lift, when the horizontal line of the top point of the included angle between the long arm and the short arm is higher than the horizontal line of the top point of the upper end of the long arm, the steel pipe slowly rolls to the next process along the long arm from the rack, circulating reciprocation is conducted according to the operation steps, and the steel pipe is firm and durable, is not easily damaged during long-time use, and is suitable for wide application and popularization.

Description

technical field [0001] The invention relates to a steel pipe conveying wheel frame of a fully automatic internal and external plastic coating production line for steel pipes, in particular an operation method for a hydraulic cylinder type lifting and unloading device for steel pipes. Background technique [0002] At present, plastic-coated steel pipe is a new type of high-efficiency anti-corrosion steel, which has excellent anti-corrosion performance, high compressive strength, long service life, smooth inner surface, and good liquid flow performance, making it quickly recognized by the market. However, my country's plastic-coated steel pipe production technology and equipment and its product status are still in the development stage, and there are many gaps compared with the more developed countries in the world. In the production of anti-corrosion steel pipes, especially in the production of anti-corrosion steel pipes with large and small diameters, most of the production ...

Problems solved by technology

However, my country's plastic-coated steel pipe production technology and equipment and its product status are still in the development stage, and there are many gaps compared with the more developed countries in the world.

In the production of anti-corrosion steel pipes, especially in the production of anti-corrosion steel pipes with large and small diameters, most of the production equipment used is independent, and each process is independently produced. At present, there are not many domestic manufacturers with large-scale production lines. For small-scale production, from process technology, equipment to product quality and production efficiency, it is still in the initial stage of development; pipeline transportation requires the cooperation of multiple people and hoisting for production. This production method is time-consuming, energy-intensive, and takes up space Large, dusty, and polluting. When many people cooperate and hoist, it often causes damage to the plastic coating layer on the surface of the steel pipe, which seriously affects the quality and service life of the product; Large, dusty, heavy pollution, the problem that the plastic coating layer on the surface of the steel pipe is easily damaged has become a technical problem that has been difficult to solve for a long time. In view of the above reasons, an operation method for the steel pipe hydraulic cylinder type lifting and unloading device is proposed.
