Abstract

The invention discloses a drawing folding device for petroleum pipeline design. The device structurally comprises a bottom plate, a fixing rod, a torsion spring, a pressing strip and a folding device.The fixing rod is welded to the middle of the bottom plate, the fixing rod is sleeved with the torsion spring, one end of the torsion spring is embedded to the bottom plate, the other end of the torsion spring is embedded into the top face of the pressing strip, the pressing strip is in fit with the bottom plate, and the folding device is connected to the side face of the bottom plate. The drawing folding device has the beneficial effects that the paper page turning action of the human body can be simulated through a paper pick-up mechanism, the excessive paper page turning phenomenon can beavoided, the skidding phenomenon is avoided since timely power is provided by an electromagnetic device for a push device, drawing can be pushed rightwards when the drawing is unfolded, page turning is assisted, the back falling phenomenon is prevented, the drawing flying phenomenon can be avoided through the pressing block, automatic page turning is achieved through the folding device, the excessive page turning phenomenon is avoided, and the error rate is reduced.

Description

technical field

[0001] The invention relates to the field of drawings, in particular to a drawing turning device for oil pipeline design. Background technique

[0002] At present, all units turn pages and stamp manually, which not only wastes manpower and is inefficient, but also many joints such as shoulders and elbows are damaged by long-term stamping, which is prone to occupational diseases. .

[0003] The existing drawing page-turning device tends to turn multiple pages during use, cannot ensure the accuracy of page-turning, and easily causes mistakes. Contents of the invention

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a drawing turning device for oil pipeline design.

[0005] The present invention adopts the following technical solutions to achieve: a drawing turning device for oil pipeline design, its structure includes a bottom plate, a fixing rod, a torsion spring, a bead, and a turning device,...
