Abstract

The utility model relates to a friction pipe wrench which is used for screwing or unscrewing a pipe and does not easily damage a surface protection layer of the pipe. The friction pipe wrench is used for reducing or avoiding damages on the surface of the pipe by a wrench opening of the pipe wrench in a process of mounting and detaching the pipe. The technical scheme is as follows: an adjusting nut is placed into a square hole of a handle body of the pipe wrench; a thread rod end of a movable wrench head is inserted into the hole of the handle body of the pipe wrench; a convex face of a friction sheet of the movable wrench head is inserted into a groove corresponding to the movable wrench head; a narrow end of a friction sheet of a fixed wrench head is inserted into a groove of the fixed wrench head from bottom to top; a substrate plate of the friction sheet of the movable wrench head is a metal substrate and friction sheet rubber of the movable wrench head is embedded on a concave arc-shaped face; a substrate plate of the friction sheet of the fixed wrench head is a metal substrate; friction sheet rubber of the fixed wrench head is embedded on the concave arc-shaped face; and lines which are at interval in vertical and transverse directions are engraved on the surface of the friction sheet rubber. According to the utility model, the contact area with the pipe is enlarged, so that the friction pipe wrench is particularly suitable for petroleum underground oil pumping rod and pipe, and an oil gas conveying pipeline, which have the strong corrosion.

Description

A kind of Friction spanner for pipe
Technical field
The utility model relates to and a kind ofly is used to screw or unscrews pipe and anodontia Friction spanner for pipe that be difficult for injury tube surface overcoat, belongs to machinery tool.
Background technology
Pipe wrench is to be used for screwing or to unscrew a kind of machine tool of pipe fitting.Usually, the pipe wrench mouth is the zigzag flank of tooth of being processed by the bigger metal material of hardness.Common pipe wrench is managed tooth by the pipe handle, regulating wheel, and the movable neck of hook is formed.The turn regulating wheel makes the pipe tooth zigzag flank of tooth closely contact with the pipe table in use; Twisting pipe handle makes the pipe fitting rotation, because the contact area of the tooth top of the pipe tooth zigzag flank of tooth and tube surface is little, contact stress is big; Be easy to destroy the overcoat of tube wall, the pipe metal surface bites.This will cause the overcoat of pipe table to be damaged, and accelerate the corrosion rate of metal tube table, particularly carry the pipeline of Korrosionsmedium, like oil well lower sucker rod, oil pipe, ground pipe-line.Serious also possibly break pipe, be out of shape by the teeth, causes material leakage in the pipe, causes very big economic loss and trouble.
For this reason, a kind of pipe wrench mouth and Friction spanner for pipe tube surface contact area, no rigid teeth of increasing of the utility model design.
Summary of the invention
The purpose of the utility model is: in the process of installation and removal pipe, reduce or avoid the damage of pipe wrench jaw to tube surface, the spy provides a kind of Friction spanner for pipe.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of Friction spanner for pipe, by pipe wrench handle body; Movable binding clip, fixed pliers head, adjusting nut; Movable binding clip friction plate, the fixed pliers head friction plate is formed, and its architectural feature is: adjusting nut is put into the square through hole of pipe wrench handle body; Adjustable clamp head thread bar one end inserts in the hole of pipe wrench handle body, and the rotation adjusting nut makes the threaded rod of movable binding clip move to the appropriate location; The laterally inserted movable binding clip of movable binding clip friction plate convex surface is with it in the corresponding groove; The narrow end of fixed pliers head friction plate inserts in the groove of fixed pliers head from bottom to top, and the convex surface of fixed pliers head friction plate and the concave surface of fixed pliers head are fitted; The substrate plate of movable binding clip friction plate is movable binding clip friction plate metallic substrates, is circular-arc, and cancave cambered surface is embedded with the movable binding clip friction plate of the hard rubber of equal thickness; The substrate plate of fixed pliers head friction plate is a fixed pliers head friction plate metallic substrates, is circular-arc, and cancave cambered surface is embedded with the hard fixed pliers head friction plate rubber of equal thickness.On movable binding clip friction plate rubber surface, be carved with oblique alternate in length and breadth lines, the cancave cambered surface groove that matches with movable binding clip friction plate metallic substrates convex surface is arranged on the movable binding clip; On fixed pliers head friction plate rubber surface, be carved with oblique alternate in length and breadth lines; The cancave cambered surface groove that matches with fixed pliers head friction plate metallic substrates convex surface is arranged on the fixed pliers head; The narrow end of fixed pliers head friction plate inserts in the pipe wrench handle body fixed pliers head groove from bottom to top, and the conical surface is locked.
The beneficial effect of the utility model is: (1) has increased and the pipe contact area, has reduced contact stress, can avoid or reduce the degree of injury to tube surface effectively; (2) can prolong service life of pipe; (3) this pipe wrench is simple, and cost is low, and it is convenient to change the arc vice jaw friction plate.
Description of drawings
Fig. 1 is the structural representation of the utility model Friction spanner for pipe.
Fig. 2 is the movable binding clip friction plate structure of this Friction spanner for pipe figure.
Fig. 3 is the movable binding clip partial structurtes of this Friction spanner for pipe sketch mapes.
Fig. 4 is this Friction spanner for pipe fixed pliers head friction plate structure figure.
Fig. 5 is this Friction spanner for pipe fixed pliers head partial structurtes sketch mapes.
Among the figure: 1. pipe wrench handle body, 2. movable binding clip, 3. fixed pliers head; 4. adjusting nut, 5. movable binding clip friction plate, 6. fixed pliers head friction plate; 7. movable binding clip friction plate metallic substrates; 8. movable binding clip friction plate rubber, 9. fixed pliers head friction plate metallic substrates, 10. fixed pliers head friction plate rubber.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
By shown in Figure 1, adjusting nut 4 is put into the square through hole of pipe wrench handle body 1, and movable binding clip 2 threaded rods one end inserts in the hole of pipe wrench handle body 1, and aims at the screwed hole of adjusting nut 4, and rotation adjusting nut 4 makes the threaded rod of movable binding clip 2 move to the appropriate location.Corresponding groove in, fit with it by male and fomale(M&F) for the horizontal insertion activity of movable binding clip friction plate 5 convex surfaces binding clip 2, and the edge alignment is also fixing.The narrow end of fixed pliers head friction plate 6 inserts in the groove of fixed pliers head 3 from bottom to top, and the concave surface of the convex surface of fixed pliers head friction plate 6 and fixed pliers head 3 is fitted, and conical surface wedging is also fixing.When using Friction spanner for pipe, movable binding clip friction plate 5 receives downward power, is born by the structural ledge of movable binding clip 2 lower ends; Fixed pliers head friction plate 6 receives power upwards, is born by the conical surface of fixed pliers head 3.The concave surface of friction plate promptly has the lines that increases frictional force with the pipe contact portion, and work a period of time is if increase the lines damage of frictional force, more renewal of facing renewal.According to the difference of pipe diameter, can use the friction plate of corresponding curvature with it.A pipe wrench can be used two to three kinds of metallic substrates unanimities, and the different friction plate of rubber face radius of curvature is to adapt to the pipe of different-diameter.
