Abstract
The utility model relates to a tractor which is used for dragging a prestress steel strand to penetrate through an outer sleeve tube of the prestress steel strand, compressing a conical cylinder. The back end of the conical cylinder is connected with an end cover on which a threaded hole is arranged. A drawbar is installed in the threaded hole of the end cover. A pressing plate and a hoop sleeve are also installed in the conical cylinder. The utility model has the advantages of convenient operation, high efficiency and reliable work.
Description
The utility model relates to the construction instrument, especially a kind of distractor that is used for the prestress wire traction is passed its outer sleeve.
Above-mentioned distractor is meant when prestress wire is passed its outer sleeve, when especially some multi beams, heavier steel strand being passed in the long or even crooked sleeve pipe, be used for prestress wire head hoop is bundled into one, be convenient to draw the utensil that passes outer sleeve, distractor of the prior art adopts finer wire to be woven into a tubular net, and at an end of net traction latch closure formation is installed.This distractor in steel strand fork networking trepanning, needs earlier net to be moved for one section one section at leisure to put outside the multiply steel wire bundle in use, and an end that will be inserted in is then tightened can implement to draw with steel wire and worn operation; When the enforcement traction wears operation, because net does not cover steel wire bundle fully, add that the appearance of net own reticulates, therefore, its resistance to motion in sleeve pipe is bigger, is stuck easily.
The purpose of this utility model provide a kind of easy to use, efficient is high, poling is easy to distractor.
For achieving the above object, the scheme that the utility model adopts is: it has the awl tube, and the rear end of this awl tube is connected with the end cap which is provided with tapped hole, in the tapped hole of this end cap draw-bar is housed; Pressing plate and hoop cover also are housed in described awl tube.
Above-mentioned hoop cover preferably which is provided with the cylindrical shell of expansion or contraction joints; Described end cap is provided with screw hole, in this screw screw is housed.
Above-mentioned awl tube is meant that its endoporus has the cylindrical shell of taper hole structure; The rear end of described awl tube is meant the bigger end of awl its taper hole bore of tube; Described hoop cover is meant the cylindrical shell that its endoporus aperture can dwindle under the effect of external force, preferably the surface is staggeredly equipped with the cylindrical shell of expansion or contraction joints.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, easy to use, efficient is high.During use, steel wire bundle is inserted in the hoop cover, similar net can not take place put the such stuck phenomenon of steel strand, and the banding steel strand only need screw in draw-bar and get final product, need not to tie up with steel wire.Therefore, easy to operate quick, efficient is high.
2, reliable operation.On the one hand, owing to adopt between draw-bar and the end cap between scyewed joint, awl tube and the hoop cover to the conical surface connects, hoop overlaps bigger to the chucking power of steel strand, and connection is firm; On the other hand, when implementing towage, steel strand are enclosed within the awl tube fully, and its front end is shaft-like, profile is tubular, with front end is that link spring shape, profile are that netted prior art is compared, and it is also comparatively agile that the utility model passes sleeve pipe, can not be stuck in the sleeve pipe.Therefore, towage is very reliable.
The utility model is described in further detail below in conjunction with the accompanying drawing example:
Fig. 1 is the prior art constructions schematic representation.
Structural representation when Fig. 2 is the utility model work.
Shown in Figure 1, the distractor of prior art is to adopt finer wire to be woven into the tubular net, and at an end of net traction latch closure formation is installed.
Among the embodiment shown in Figure 2, the utility model is made of draw-bar 1, end cap 2, screw 3, pressing plate 4, awl tube 5 and hoop cover 6.Awl tube 5 is one to be the cylinder of taper hole in it, the rear end of awl tube 5, it is the big end of its taper hole bore, be connected with the end cap 2 which is provided with tapped hole, also be provided with screw hole on the end cap 2, the screw 3 of stopping function is housed in this screw hole, draw-bar 1 is housed in the tapped hole of end cap 2, by screwing in screw 3, draw-bar 1 can be fixed in the end cap 2; Pressing plate 4 and hoop cover 6 also are housed in awl tube 5 successively, and hoop cover 6 is cylindrical shells that the surface is staggeredly equipped with expansion or contraction joints.
The utility model in use, prestress steel twist wire harness 7 can be inserted in the hoop cover 6, screw in draw-bar 1, and will bind round the front end that cover 6 is pressed to awl tube 5 by draw-bar 1, pressing plate 4, hoop cover 6 dwindles under the effect of taper hole, with steel wire bundle 7 bandings, tighten screw 3 at last and just can implement to draw the operation that wears.
