Abstract

The utility model belongs to a rig tensioning tooling, and particularly relates to a continuous operating rig tensioning tooling, which solves problems that the existing rigs can not be operated continuously when in tensioning and tensioning precision thereof and are hard to be controlled. The continuous operating rig tensioning tooling comprises a front clamping plate, a rear clamping plate and a screw-nut pair for connecting the two clamping plates, wherein an automatic locking mechanism is arranged at a position for penetrating a steel strand, the automatic locking mechanism comprises a return clamping anchor plate, one side of a tension direction of the return clamping anchor plate is connected to the front clamping plate via a return spring, a wedge is arranged on the outer side of the return clamping anchor plate and fixed on the front clamping plate, and the end of the side of the tensioning direction of the return clamping anchor plate is higher than the end of the other side thereof. The continuous operating rig tensioning tooling has the advantages that continuous tensioning can be realized, and time for intermittent operation is saved. In addition, because the steel strand is tightened, extension of the rig can be controlled accurately by aid of a scale on the tooling during tensioning, rig force can be controlled to meet design requirements, and then the rig tensioning tooling has high control precision which is unmatched compared with the original tooling.

Description

A kind of rigging stretch-draw frock of working continuously
Technical field
The utility model belongs to lockset stretch-draw frock, is specifically related to a kind of rigging stretch-draw frock of working continuously, and uses precision in the time of can improving rigging stretch-draw operation and stretch-draw efficient when being applied to the stretch-draw of building structure construction rigging.
Background technology
When existing building structure rigging stretch-draw operation, the stretch-draw operation is stage to be carried out, and can't realize working continuously, after the stretch-draw once, need the stretch-draw jack is come loose, and the oil pump oil return, the ground tackle pine lags, and carries out second circulation stretch-draw again.Such stretch-draw operation, operation process can't be continuous, and the mensuration of stretching force is difficult for carrying out, and the stretch-draw precision is difficult to control, and stretch-draw operation process efficient is low, and the time is long.
Summary of the invention
The utility model can not be worked continuously when solving existing rigging stretch-draw, and the unmanageable problem of stretch-draw precision provides a kind of rigging stretch-draw frock of working continuously, working continuously and the accurate control of stretching process when having realized rigging stretch-draw.
The utility model adopts following technical scheme to realize:
The rigging stretch-draw frock of working continuously, comprise front plate, rear plate and the feed screw nut pair that connects the two, it is characterized in that the position that wears steel strand in the front plate is provided with automatic locking mechanism, described automatic locking mechanism comprises that the backhaul that is sandwiched in the steel strand both sides clamps the anchor sheet, the side that backhaul clamps the stretch-draw direction of anchor sheet is connected on the front plate by return spring, the outside that backhaul clamps the anchor sheet is a voussoir, voussoir is fixed on the front plate, and the end of backhaul clamping anchor sheet stretch-draw direction one side is higher than the end of opposite side.
The scale of mensurable tentioning stroke is set between front plate and the rear plate.
Compared with prior art, the beneficial effects of the utility model are: when rigging stretch-draw operation, can realize continuously tensioning, can improve 3-4 doubly than original rigging stretch-draw frock, save the batch operation time.Simultaneously, because steel strand are lax, the elongation of rigging when utilizing scale on the frock accurately to control stretch-draw, control cord power is to designing requirement, and the control accuracy height is that original frock is incomparable.
Description of drawings
Fig. 1 is a vertical view of the present utility model
Fig. 2 is a perspective view of the present utility model
Fig. 3 is the A portion enlarged drawing of Fig. 1
Among the figure: 1-stretch-draw jack, the 2-steel strand, the 3-front plate, the 4-return spring, the 5-backhaul clamps anchor sheet, 6-voussoir, 7-scale, 8-cable wire tapered end, 9-feed screw nut pair, 10-rear plate.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
The rigging stretch-draw frock of working continuously, comprise front plate 3, rear plate 10 and the feed screw nut pair 9 that connects the two, it is characterized in that the position that wears steel strand 2 in the front plate 3 is provided with automatic locking mechanism, described automatic locking mechanism comprises that the backhaul that is sandwiched in steel strand 2 both sides clamps anchor sheet 5, the side that backhaul clamps the stretch-draw direction of anchor sheet 5 is connected on the front plate 3 by return spring 4, the outside that backhaul clamps anchor sheet 5 is a voussoir 6, voussoir 6 is fixed on the front plate 3, and the end of backhaul clamping anchor sheet 5 stretch-draw directions one side is higher than the end of opposite side.
The scale 7 of mensurable tentioning stroke is set between front plate 3 and the rear plate 10.
Adopt return spring 4 to clamp the method that anchor sheet 5 combines with backhaul, the continuity when realizing the stretch-draw operation.In stretching process, stretch-draw jack 1 oil cylinder stretches out, anchor sheet in the stretch-draw jack 1 clamps steel strand 2, it is lax that backhaul clamps anchor sheet 5, under jack operation power, stretch-draw jack 1 hauls steel strand 2 and moves forward, makes the ground tackle elongation, make the steel wire elastic elongation in the ground tackle, realize applying of internal force.After jack was finished a stroke, jack cylinder needed backhaul, at this moment, anchor sheet in the jack is in lax, head on backhaul clamping anchor sheet 5 by rebound spring 4 strength and in the moment of jack oil return steel strand 2 are clamped, when jack oil return return, steel strand 2 can not relax yet like this.After the jack oil return finished, jack stretched out, and carries out the stretch-draw operation of next one stage again.Thereby under the unflagging situation of steel strand, realize carrying out continuously of ground tackle stretch-draw operation.
In this stretch-draw frock, utilize steel strand unflagging characteristic in stretching process, at the other scale 7 that is provided with of frock, be used for Continuous Observation, the elongation of rigging in the stretching process helps operation, more help controlling the stretch-draw precision, make the stretch-draw curve more meet designing requirement.

Claims (2)
