Abstract

The utility model discloses a kind of construction tool, be mainly used in all kinds of tubing connection construction connected with silk mouth, the construction tool especially used during the operation of tunnel Shed-pipe Advanced Support.It includes handle and is hinged on the chain of handle one end, and its key technology is to be respectively equipped with flank and hook in the opposition side, two, handle front end being positioned at chain one end.This utility model ensures during pipe canopy precession, and two pieces of flanks can be in close contact with steel tube surface, is difficult to slip and comes off, and adapts to the tubing in the range of larger diameter.

Description

The construction tool connected for pipe canopy silk mouth in pipe roof construction

Technical field

This utility model relates to a kind of construction tool, is mainly used in all kinds of tubing connection construction connected with silk mouth, especially The construction tool used when being tunnel Shed-pipe Advanced Support operation.

Background technology

During constructing tunnel, when entering at the unstable surrounding rock of hole and pass through weak broken wall rock area, for ensureing tunnel excavation Construction safety, need to carry out advance support operation at face, frequently with scheme be by pipe roof construction.Owing to every pipe canopy is It is formed by connecting by silk mouth by plurality of sections of steel pipes, needs to creep into section by section in practice of construction.In current pipe roof construction, between saving and saving How to connect assembly by pipe wrench, and owing to actual face construction space is limited, pipe wrench seems and is necessarily large and bulky, operating difficulties, and Pipe wrench contacts not tight with steel tube surface, and easily sliding comes off, and splices inefficiency, affects efficiency of construction.

Summary of the invention

Problem to be solved in the utility model is aiming at above deficiency and provides a kind of and contact closely with steel tube surface, no Easily slide the instrument for pipe roof construction come off.Its technical scheme is as follows:

This utility model includes handle and is hinged on the chain of handle one end, and its key technology is being positioned at chain one end Opposition side, two, handle front end is respectively equipped with flank and hook.

A circular groove is had between described flank.

Compared with prior art, this utility model has the beneficial effect that

1, it is respectively equipped with flank and hook in handle front end.The quantity of flank is 2, the degree of depth of the screw thread of each For 0.1cm, screw thread the frictional force that can improve contact surface with pipe canopy is set, and have between two pieces of flanks Radius be about 1～ The circular groove of 2cm, this makes, when pipe canopy diameter changes greatly, two pieces of flanks to be made closely to connect with Guan Peng surface Touch；The quantity of hook is 1～2, and the degree of depth is 1～2cm, and in work progress, the chain other end is stuck in pocket for the punch head, it is ensured that chain Being completely embedded property, chain length is increased or decreased unit according to pipe canopy diameter, with flexible length.Such structure energy Ensureing during pipe canopy precession, two pieces of flanks can be in close contact with steel tube surface, is difficult to slip and comes off, and adapts to relatively Tubing in the range of major diameter.

2, this utility model portable construction is practical, simple to operate, only need to commonly manually perform, it is not necessary to special set by other For being rapidly completed pipe canopy silk mouth connection work, ensureing pipe canopy joint efficiency in certain small space, contrast uses pipe wrench Deng other construction tools, it is greatly saved expense and time, quickness and high efficiency, is integrally improved constructing tunnel efficiency.

Accompanying drawing explanation

Fig. 1, is this utility model structural representation；

Fig. 2, is this utility model precession operating diagram；

Fig. 3, is that this utility model turns round operating diagram.

The represented position of numbering in figure:

1 chain, 2 handles, 3 hooks, 4 flanks, 5-circular groove.

Detailed description of the invention

Seeing Fig. 1～Fig. 3, this utility model includes handle 2 and is hinged on the chain 1 of handle 2 one end, and its key technology is It is respectively equipped with flank 4 and hook 3 in the opposition side, two, handle front end being positioned at chain one end.

A circular groove 5 is had between described flank 4.

The degree of depth of described circular groove 5 is 1～2cm.

Described handle 2 long 30～40cm, wide 3～4cm, thick 1～1.2cm.

The thickness 0.8～1cm of described chain 1, width 0.8～1cm.

The quantity of described hook 3 is 1～2.

The degree of depth of described hook 3 is 1～2cm.

This utility model using method is as follows:

Seeing Fig. 2, during connecting tube canopy, chain is at the position winding pipe canopy 6 one weeks near interface, and chain afterbody hooks handle The hook of front end, makes chain and handle nose threads face be close to pipe canopy 6, and the opposite direction of handle end point tube canopy precession.With Hands is pulled handle and is rotated towards pipe canopy 6 precession direction, then pipe canopy can be followed by the frictional force of chain with the flank of handle front end Rotate.See Fig. 3, when, after precession certain angle, opposite direction turning handle, pipe canopy remains stationary as, and chain and handle opposite direction turn Move to replying home position；Again towards precession direction turning handle, then pipe canopy 6 continues to follow rotation.And so forth, can be the completeest Become the 6 mouth connection work of pipe canopy.After pipe canopy 6 has connected, chain is taken off from hook, easy to use.
