Description
Technical field
The utility model belongs to construction equipment field in subway tunnel, is related to a kind of tensioner, and in particular to a kind of subway
Tunnel ductile iron pipeline installs tensioner.
Background technique
Currently, the installation of subway tunnel Nodular Cast Iron Pipes road is mostly the mounting structure of spigot-and-socket, moves towards and hold in pipeline
It is mostly to fix both ends with rope when inserting, using cylinder rod principle by crow bar progress socket joint, there are problems that socket joint low efficiency, and
The pipe at when socket joint it is difficult to ensure that both ends is on same straight line, and socket joint difficulty is big, installation quality is not high, waste of manpower.
By retrieval, patent document identical or similar with the utility model patent is not yet found.
Summary of the invention
That the purpose of this utility model is to provide a kind of socket joints is high-efficient, facilitates operation, improve installation quality, saves people saves
Power, the subway tunnel ductile iron pipeline being easily achieved install tensioner.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of subway tunnel ductile iron pipeline installation tensioner, it is characterised in that: by pipe clamp, hydraulic telescopic arm, stroke
Scale and power unit are constituted, and described pipe clamp or so is oppositely arranged, and the upper and lower ends between two pipe clamps are symmetrically installed with
Hydraulic telescopic arm, the telescopic rod of hydraulic telescopic arm drive two pipe clamps close to or far from installing on the hydraulic telescopic arm of upper end
Have it is horizontally disposed flexible stroke scale can be carried out according to the telescopic rod of hydraulic telescopic arm, the hydraulic telescopic arm passes through pipe
Road is connect with power unit.
Moreover, the pipe clamp is made of preceding clamp arm, rear clamp arm, compression bar and mounting blocks, the preceding clamp arm and rear clamp arm
Dress is mutually cut with scissors in one end, and the other end of preceding clamp arm and rear clamp arm is connected and fixed by compression bar, is mounted in the upper and lower ends of pipe clamp
Mounting blocks, the hydraulic telescopic arm are mounted on the mounting blocks.
Moreover, being evenly equipped with anti-skid teeth on the inner wall of the pipe clamp.
Moreover, the power unit is made of miniature gasoline engine and hydraulic cylinder connected to it.
It the advantages of the utility model and has the beneficial effect that
1, this subway tunnel ductile iron pipeline installs tensioner, and miniature gasoline engine band hydraulic cylinder needs socket joint pair
Two cast iron pipes connect are fixed in interface two sides by pipe clamp, and pipe clamp is driven by two hydraulic telescopic arms, when work, operate hydraulic stretches
Contracting arm, shrinks hydraulic telescopic arm, and two sides cast iron pipe is driven to move toward one another, and carries out socket joint movement, ensure that two sides cast iron pipe energy
Opposite socket joint is carried out along straight line, construction quality is high.Pay close attention to stroke scale simultaneously, when mobile display distance is met the requirements and
When the cast iron pipe of two sides cannot move again in the axial direction, then socket joint is met the requirements.The setting of stroke scale ensure that holding for pipeline
Quality is inserted, socket joint depth is judged by the numerical value on stroke scale, avoids ensure that and applying using naked-eye observation bring error
Working medium amount avoids blocking because of pipeline, and caused by socket joint the illusions such as finish, guarantee the stability after pipeline spigot-and-socket.
2, this subway tunnel ductile iron pipeline installs tensioner, can by anti-skid teeth uniformly distributed on the inner wall of pipe clamp
Guarantee pipe clamp and cast iron pipe fixation, guarantees being normally carried out for construction.
3, the utility model scientific structure design is reasonable, with socket joint is high-efficient, facilitate operation, improves installation quality, province
People is laborsaving, the advantages of being easily achieved, and is a kind of subway tunnel ductile iron pipeline installation tensioner.
