Problems solved by technology

This scheme adds an operator, which increases the cost of thickening
Moreover, human visual supervision cannot be foolproof. When the bending state of the tube material is near the critical point, the human eye cannot make timely and accurate judgments, and there is still a risk of collision between the tube material and the induction heater.

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 , figure 2 with image 3 As shown, the anti-collision mechanism for the intermediate frequency induction heater of the thickening production line of the present invention includes a base 1, on which the pillars 4 arranged side by side are fixed, and the top ends of the pillars 4 are connected with a horizontal shaft 6, and the horizontal shaft 6 and the pillars 4 Both are rotationally fitted.

[0020] A bracket is fixed above the horizontal rotating shaft 6, and there are limit holes 8 arranged horizontally on the bracket. Described support is square frame 7, and the middle part of every side of this square frame 7 all has screw hole, and screw rod 9 is all arranged in the screw hole, and the two ends of screw rod 9 all protrude outside screw hole and all have locking nut on it 10. The axes of the screw rods 9 all pass through th...

Abstract

The invention relates to the technical field of petroleum and natural gas drill rod machining, in particular to an anti-collision mechanism for a medium-frequency induction heater of a thickening production line, which is used in a thickening process of petroleum and natural gas drill rods. The anti-collision mechanism for the medium-frequency induction heater of the thickening production line ischaracterized by comprising a base, wherein supporting columns arranged side by side are fixed onto the base; a horizontal rotating shaft is connected between the top ends of the supporting columns; and the horizontal rotating shaft is in running fit with the supporting columns. A support is fixed to the upper part of the horizontal rotating shaft; and a horizontally-arranged limiting hole is formed in the support. A first swing rod is fixed below the horizontal rotating shaft, and a contact switch is arranged on the base corresponding to the lower end of the first swing rod. The anti-collision mechanism is arranged at the front end of an inlet of the medium-frequency induction heater, so that a severely bent pipe can be effectively prevented from approaching the induction heater, the collision between the pipe and the induction heater is thoroughly avoided, and meanwhile, the energy consumption and the thickening cost are not increased.

Description

technical field [0001] The invention relates to the technical field of oil and gas drill pipe processing, in particular to an anti-collision mechanism for an intermediate frequency induction heater in a thickening production line used in the thickening process of oil and natural gas drill pipes. Background technique [0002] Thickening is an important process in the production of drill pipe for oil and gas drilling, thickened tubing and casing for oil and gas, and drill pipe for trenchless construction. The outer diameter of the pipe end of the drill pipe body is increased, or the inner diameter is reduced, or the inner diameter is reduced while the outer diameter is increased. In short, the wall thickness of the pipe material is increased. It is a hot forging production process. Medium-frequency induction heating has fast speed, high efficiency, less oxidation, high temperature control precision, and easy automatic operation. Therefore, medium-frequency induction heating i...
