Abstract
The invention discloses a shifting torque spanner. The shifting torque spanner comprises a head part, an elastic torsional rod, a suspension pointer arm, a pointer, a dial scale and a handle sleeve, wherein a handle is arranged on the lower edge of the head part; the upper end part of the suspension pointer arm is fixedly connected to the handle, and the pointer is connected to the lower end of the suspension pointer arm; the elastic torsional rod is connected between the handle and the handle sleeve; the dial scale is fixed to the handle sleeve or the pointer; a deformation angle can be observed according to the stressing deformation of the elastic torsional rod. The shifting torque spanner is easy to produce and manufacture, convenient to use, and resistant to impacting; the shifting torque spanner can be used in positive and negative directions, and the torque value can be directly observed, so that the visibility is high; the labor intensity can be reduced; the construction efficiency can be improved; the construction cost can be decreased.
Description
Technical field
The present invention relates to spanner technical field.
Background technology
According to the construction of GB50233 mono-2005(110kv-500kv aerial power transmission line and acceptance specification) the mandatory execution provision of 6.1.6 bar regulation, bolt connects and uses torque spanner must reach the torque value of defined.Particularly overhead transmission line strain insulator wire jumper connects the device clamp that (parallel groove clamp, drainage plate) all adopts 2 connecting bolts, the contact reliability that bolt torque values carrys out control connection node need be detected with torque wrench. the assembling that refer to overhead transmission line shaft tower especially uprightly requires that connecting bolt is fastening one by one, the assembling of shaft tower uprightly requires to use torque wrench when just filling, connecting bolt should be all once fastening again after the assembling of overhead transmission line shaft tower is upright, also should tighten up once after stringing and check torque value, the tightening torque of bolt must not be less than setting.
Existing torque wrench is fastening bolt when steel tower assembling is upright, in use has following problem:
(1) realize the apparatus structure that moment of torsion controls complicated, dial type torque wrench needs frequently to change pullover, pulloverly easily comes off.
(2) length of torque wrench makes torque value observe difficulty, and when spanner oppositely uses, torque value cannot be observed.
(3) length of torque wrench is comparatively large, and use inconvenient in the little space that tower material is narrow, that can not fit applying multi-standard bolt tightens requirement.
(4) minor impact during in-site installation easily makes torque values distortion.
(5) existing torque wrench is precision instruments, and instrument cost is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of survivor of a murder attempt's torque wrench, has structure simple, easy to use, the feature that wrenching torque value is easily observed.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of survivor of a murder attempt's torque wrench, comprise Wrench head, elastic torsion bar, unsettled pointer arm, pointer, dial and Handle cover, described Wrench head following with one section of handle, described unsettled pointer arm upper end is fixedly connected with handle, at unsettled pointer arm lower end concatenation pointer, described elastic torsion bar is connected between handle and Handle cover, described dial is fixed on Handle cover or is fixed on pointer, observes deformation angle by the stress deformation of elastic torsion bar.
To the further improvement that the present invention does be: described elastic torsion bar is the sleeve pipe that spring steel wire is filled in inside, the length of described spring steel wire is identical with casing length, spring steel wire is longitudinally arranged closely in sleeve pipe, the periphery at described sleeve pipe both ends is polygon through extruding cross section, sleeve is respectively equipped with at sleeve pipe both ends, the sleeve on top inserts the middle part of handle and is welded to connect, and the sleeve of bottom inserts Handle cover and is welded to connect; Set up cushion block, the cross section of described unsettled pointer arm is groove type, and described cushion block is fixed in the middle part of handle, and two screw fastenings are passed through on cushion block in the upper end of unsettled pointer arm.
The beneficial effect adopting technique scheme to produce is:
One, spring steel wire steel wire can reduce rapidly after elastic torsion bar is stressed, can avoid plastic deformation.
Two, the sleeve at elastic torsion bar both ends can prevent multi-strand spring steel wire from when stressed, broken lot occurring, and increases integral rigidity.
Three, sleeve can avoid elastic torsion bar to damage in operation, avoids torque value distortion.
Four, sleeve pipe termination is pressed into six side's shapes and can prevents that spanner in use occurs and pull tail distortion.
Five, spanner positive direction uses or uses in the other direction, and all can observe directly torque value, intuitive is strong.The present invention easily manufactures, impact resistance easy to use, can accurate observation torque value, can reduce labour intensity, improves efficiency of construction, reduces construction cost.
