Abstract
The utility model discloses a kind of steel strand penetrating devices, comprising: sleeve, axially disposed several major thread holes on the circumferential surface of the sleeve, fastening bolt is screwed in by major thread hole to be extended to the inner cavity of sleeve and compress steel strand wires；It is sleeved on the slippery fellow of steel strand wires front end, several minor thread holes are uniformly arranged in the circumferential direction on foxy circumferential surface, screw is screwed in the front end that slippery fellow is fastened on to steel strand wires by minor thread hole；Propulsion arm, the front end of propulsion arm are equipped with disk, circumferentially distributed a pair of of the protrusion of the leading flank of disk, the rear end of the protrusion pushing tow sleeve.The utility model structure is simple, low in cost, easy to use, and incremental launching device can be cooperated to carry out quick lashing to steel strand wires, improve lashing efficiency.
Description
Technical field
The utility model belongs to bridge construction engineering field more particularly to a kind of steel strand penetrating device.
Background technique
In the construction of pre-stressed bridge, there are many steel strand wires to need lashing, especially post-tensioned construction, in prestressing force
After the completion of beam pours, it is necessary to penetrate steel strand wires in duct, traditional steel stranded wire penetrating adapter mode has artificial lashing, hoist engine to lead
Beam is pulled through, in the bridge construction of some large sizes, since the quantity of every beam steel strand wires is more and longer, artificial lashing efficiency
Low, speed is slow, and hoist engine drawing is easily damaged steel strand wires, and certain difficulty is brought to lashing.
Utility model content
To solve the above problems, the utility model proposes a kind of steel strand penetrating device, apparatus structure letters
It is single, it is low in cost, it is easy to use, incremental launching device can be cooperated to carry out quick lashing to steel strand wires, improve lashing efficiency.
To achieve the goals above, the utility model uses following scheme, comprising:
Sleeve, axially disposed several major thread holes on the circumferential surface of the sleeve, fastening bolt is screwed in by major thread hole stretches
Steel strand wires are compressed to the inner cavity of sleeve；It is sleeved on the slippery fellow of steel strand wires front end, is uniformly arranged in the circumferential direction on foxy circumferential surface several
Minor thread hole, screw are screwed in the front end that slippery fellow is fastened on to steel strand wires by minor thread hole；The front end of propulsion arm, propulsion arm is equipped with circle
Disk, circumferentially distributed a pair of of the protrusion of the leading flank of disk, the rear end of the protrusion pushing tow sleeve.
Axially disposed major thread hole is two on the circumferential surface of the sleeve.
When lashing, steel wire bundle is penetrated from the rear end of sleeve, front end is pierced by, it is set with slippery fellow in the front end of steel wire bundle,
The front end that slippery fellow is fastened on steel wire bundle by the screw on slippery fellow is tightened, fastening bolt is tightened and compresses steel wire bundle, by pushing tow
The protrusion of bar front end withstands the rear end of sleeve, and the tail end of steel wire bundle is reused pushing tow and set by stretching out in the gap between protrusion
The rear end of standby pushing tow propulsion arm, i.e. progress lashing.
The utility model structure is simple, low in cost, easy to use, incremental launching device can be cooperated to carry out steel strand wires quick
Lashing improves lashing efficiency.
Detailed description of the invention
Fig. 1 is the utility model broken section schematic view of the front view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, so that those skilled in the art can be more
Add and be apparent from, as shown in Figure 1, the utility model uses following scheme, comprising:
Sleeve 1, axially disposed several major thread holes on the circumferential surface of the sleeve 1, fastening bolt 2 are screwed in by major thread hole
The inner cavity for extending to sleeve 1 compresses steel strand wires 6；It is sleeved on the slippery fellow 3 of steel strand wires front end, is circumferentially uniformly set on the circumferential surface of slippery fellow 3
Several minor thread holes are set, screw 4 is screwed in the front end that slippery fellow 3 is fastened on to steel strand wires 6 by minor thread hole；Propulsion arm 5, propulsion arm 5
Front end be equipped with disk, circumferentially distributed a pair of of the protrusion of the leading flank of disk, the rear end of the protrusion pushing tow sleeve 1.
Axially disposed major thread hole is two on the circumferential surface of the sleeve 1.
When lashing, steel wire bundle is penetrated from the rear end of sleeve, front end is pierced by, it is set with slippery fellow in the front end of steel wire bundle,
The front end that slippery fellow is fastened on steel wire bundle by the screw on slippery fellow is tightened, fastening bolt is tightened and compresses steel wire bundle, by pushing tow
The protrusion of bar front end withstands the rear end of sleeve, and the tail end of steel wire bundle is reused pushing tow and set by stretching out in the gap between protrusion
The rear end of standby pushing tow propulsion arm, i.e. progress lashing.
The utility model structure is simple, low in cost, easy to use, incremental launching device can be cooperated to carry out steel strand wires quick
Lashing improves lashing efficiency.
