Abstract
The invention discloses a kind of tensioner, apply in field of electricity construction.Including bottom joist, straining pulley and the wire-crossing wheel on tensioner chassis, wire-crossing wheel is located at below straining pulley, at least it is divided into two sections and is worn by support rail and is connect, installation support chip is set above the joist of bottom, support chip top is provided with semicircle groove, and support rail is placed in the semicircle groove.After the present invention installs support chip additional, because support chip serves support and the effect of stress to support rail and wire-crossing wheel, tensioner can effectively be prevented in normal operating conditions because tension force is inadequate, wire tenesmus on straining pulley when being contacted with wire-crossing wheel wire-crossing wheel stress it is overweight and make support rail flexural deformation, wire-crossing wheel and wire is set to cause to wear, so as to effectively extend the usage time of wire-crossing wheel and wire, maintenance cost is reduced.
Description
Technical field
The present invention relates to a kind of tensioner, in particular to a kind of tensioner that can extend the life-span, apply in power construction
Field.
Background technology
Tensioner is the plant equipment used when erecting power transmission lines, is used for during trailing cable and pull rope
Tension force is provided to pull rope or cable, prevents that unwrapping wire is too fast.The straining pulley of tensioner is arranged on chassis, is below straining pulley
One bottom joist, wire-crossing wheel is provided with the joist of bottom, wire-crossing wheel is to be arranged on by the support bar of transverse direction on the joist of bottom, branch
Respectively there is a strong point at the both ends of strut with bottom joist.At the scene during unwrapping wire, tensioner tension force is inadequate sometimes, causes under wire
Pendant, wire can directly push wire-crossing wheel, cause the support bar flexural deformation of wire-crossing wheel, cause the damage of wire wire-crossing wheel, increase
Maintenance cost.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of tensioner that can extend wire-crossing wheel service life.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of tensioner, including installed in tension force
Bottom joist and straining pulley on machine chassis, the wire-crossing wheel on the joist of bottom, the wire-crossing wheel are at least divided into two sections simultaneously
Worn and connect by support rail, at least three support chips are set on the joist of bottom, the support chip top is provided with semicircle groove, branch
Support cross bar is placed in the semicircle groove, and support chip is supported between two sections of adjacent wire-crossing wheels and the wire-crossing wheel at both ends
Outside.
Further improvement of the present invention is：Support chip top semicircle groove internal diameter is corresponding with the external diameter of support rail, branch
The width of blade is 10mm.
Further improvement of the present invention is：Support chip uniform intervals set 3.
By adopting the above-described technical solution, the technological progress acquired by the present invention is：
The present invention makes support rail will not be because of wire by setting installation support chip above the bottom joist of tensioner
Generation flexural deformation is pushed, the service life for extension lead and wire-crossing wheel.The width of support chip is 10 mm, support chip
The internal diameter fastening corresponding with the external diameter of support rail for the semicircle groove that top is set, tension force motor spindle at least provided with 3 support chips,
A centrally disposed support chip for support rail, the outside of left and right ends wire-crossing wheel respectively sets a support chip, for stablizing chain
Support rail and bottom joist are connect, the wire for preventing from winding on straining pulley makes support rail stress in the not enough tenesmus of tensioner tension force
Overweight to cause flexural deformation, ensureing to deform because of support rail in normal operation in tensioner damages wire-crossing wheel
Wire is worn and causes production accident.
Brief description of the drawings
Fig. 1 is：The straining pulley of the present invention and wire-crossing wheel and the schematic diagram of support chip；
Fig. 2 is：The support chip side view of the present invention；
In figure：1st, wire-crossing wheel, 2, support chip, 3, bottom joist, 4, straining pulley, 5 wires, 6, support rail.
Embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of tensioner, including bottom joist 3 and straining pulley 4 on tensioner chassis, tension force
Wheel 4 is located at the top of bottom joist 3, and wire-crossing wheel 1 is arranged on bottom joist 3, and wire-crossing wheel 1 is located at the lower section of straining pulley 4 in tension force
Wire-crossing wheel 1 is used for supporting the wire 5 on straining pulley 4 during machine unwrapping wire, as illustrated in fig. 1 and 2, installation is set above bottom joist 3
Support chip 2, the width of support chip 2 is 10mm, and top is provided with semicircle groove, the semicircle groove internal diameter and support rail 6
External diameter is corresponding, can make support chip 2 and the stable occlusion of support rail 6, support chip 2 with the central point of tension force motor spindle joist 3 to the left
To both ends uniform intervals at least provided with 3, support chip 2 is supported on the line excessively between two sections of adjacent wire-crossing wheels 1 and both ends on the right side
The outside of wheel 1, support rail 6 is linked with the stabilization of bottom joist 3, can effectively prevent because wire 5 is overweight by support rail 6
Deformation is bent, wire 5 is caused breakage with the improper friction of wire-crossing wheel 1 when tensioner works.
