Abstract
The utility model relates to a pair of pipe tongs with a replaceable jaw. The pipe tongs with the replaceable jaw are used for screwing or unscrewing a pipe and can lower or avoid damage to the surface of the pipe from the jaw of the pipe tongs when the pipe is installed and detached. According to the technical scheme, an adjustment nut is put into a through hole of a handle body of the pipe tongs, a threaded rod end of a movable tong head is inserted into the hole of the handle body of the pipe tongs, teeth on a tooth surface of a friction block of the movable tong head are embedded into teeth of the movable tong head, teeth on a tooth surface of a friction block of a fixed tong head are embedded into teeth of the fixed tong head, teeth on a plane of the friction block of the movable tong head are matched with the teeth of the movable tong head, a friction rubber block of the movable tong head is fixed to a concave arc surface of the other surface, teeth on a plane of the friction block of the fixed tong head are matched with the teeth of the fixed tong head, a friction rubber block of the fixed tong head is fixed to a concave arc surface of the other surface, and inclined lines which longitudinally and transversely intersect are carved on the surface of each friction rubber block. The pipe tongs effectively avoid or lower the damage degree to the surface of the pipe, prolong the service life of the pipe and are simple in structure and low in cost, and the rubber blocks can be replaced conveniently.
Description
Technical field
The utility model relates to and is a kind ofly used for protection tube sub-surface overcoat and can change the pipe wrench of jaw for what screw or unscrew pipe.
Background technology
Pipe wrench is the machine tool for screwing or unscrew pipe fitting.Conventional pipe wrench jaw is the zigzag plane of being made up of the larger metal material of hardness.Common pipe wrench is by pipe handle, pipe tooth, regulating wheel, movable neck of hook composition.When use, rotate regulating wheel and just can change the interplanar distance of two teeth, make zigzag plane and the tube surface close contact of pipe tooth, then rotate pipe handle and make pipe rotation.Due to the tooth top of pipe tooth zigzag plane and the contact area of tube surface less, contact stress is large, the overcoat of tube wall is easy to be damaged, pipe metallic matrix bites.This is by accelerating the corrosion rate of metal tube table, more obvious when oil sector transporting wellhead sulfur-containing gas or saltwater brine; Tracheae in residence district and family, water pipe be common to be had because of the tube surface overcoat local phenomenon that produces corrosion of being bitten, and serious also may break pipe by the teeth and leak, and causes economic loss and trouble.For this reason, a kind of pipe wrench friction jaw that can change, that can increase the pipe table that do not bite with pipe contact area of the utility model design.
Summary of the invention
The purpose of this utility model is: in the process of installation and removal pipe, reduce or avoid the damage of pipe wrench jaw to tube surface, spy provides a kind of pipe wrench that can change jaw.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of pipe wrench that can change jaw, by pipe wrench handle body, movable binding clip, fixed pliers head, adjusting nut, movable binding clip brake pad, fixed pliers head brake pad composition, its architectural feature is: adjusting nut is put into the square through hole of pipe wrench handle body, in the hole of adjustable clamp head thread bar one end Inserting Tube clamp handle body, rotation adjusting nut makes the threaded rod of movable binding clip move to appropriate location; In movable binding clip brake pad flank of tooth tooth embedding activity binding clip tooth, by magnetic attraction; Fixed pliers head brake pad flank of tooth tooth embeds in fixed pliers head tooth, by magnetic attraction; The substrate plate of movable binding clip brake pad is metallic substrates, and the tooth in plane mates with the tooth of the movable binding clip of pipe wrench, and it is circular-arc that another side is, and cancave cambered surface is fixed with movable binding clip friction block rubber; The substrate plate of fixed pliers head brake pad is metallic substrates, and the tooth in plane mates with the tooth of pipe wrench fixed pliers head, and it is circular-arc that another side is, and cancave cambered surface is fixed with fixed pliers head friction block rubber.On the surface of fixed pliers head friction block rubber and movable binding clip friction block rubber, carve and mould oblique alternate lines in length and breadth.
The beneficial effects of the utility model are: when (1) this pipe wrench required torque is little, friction jaw can increase and pipe contact area, reduces contact stress, effectively avoid or reduce the degree of injury to tube surface, extend the service life of pipe; (2), when this pipe wrench needs high pulling torque, can take off easily friction jaw; (3) this pipe wrench friction clamp mouth structure is simple, and cost is low, changes block rubber convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model can be changed the pipe wrench of jaw.
Fig. 2 is the structure chart of the movable binding clip brake pad 5 of this pipe wrench.
Fig. 3 is the structure chart of this pipe wrench fixed pliers head brake pad 6.
In figure: 1. pipe wrench handle body, 2. movable binding clip, 3. fixed pliers head, 4. adjusting nut, 5. movable binding clip brake pad, 6. fixed pliers head brake pad, 7. movable binding clip friction block rubber, 8. fixed pliers head friction block rubber.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail
Press shown in Fig. 1, adjusting nut 4 is put into the square through hole of pipe wrench handle body 1, in the hole of movable binding clip 2 threaded rod one end Inserting Tube clamp handle bodies 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 appropriate location.In the time that required torque is not too large, movable binding clip brake pad 5 inserts from the side of movable binding clip 2, and the plane tooth of movable binding clip brake pad 5 and movable binding clip 2 plane dental articulations, by magnetic attraction; Fixed pliers head brake pad 6 inserts from the side of fixed pliers head 3, and the plane tooth of fixed pliers head brake pad 6 and fixed pliers head 3 plane dental articulations, by magnetic attraction.The active force rubbing when work on rubber passes to the tooth of pipe wrench by the tooth of brake pad.By according to the variation of pipe diameter size, can use the brake pad of the friction rubber radius of curvature adapting with it.When required torque is larger, the brake pad on movable binding clip and fixed pliers head is taken off.
