The utility model discloses the easy manufacturing, the resistant striking of convenient to use, two positive and negative directions are used, but direct observation to torque values all, nature directly perceived is strong. Can reduce intensity of labour, improve the efficiency of construction, reduce construction cost.
Description
Technical field
The utility model relates to spanner technical field.
Background technology
According to GB50233 mono-2005(110kv mono-500kv aerial power transmission line construction and acceptance specification) the mandatory execution provision of 6.1.6 bar regulation, bolt connects the torque value that uses torque spanner must reach defined. Particularly overhead transmission line strain insulator wire jumper connection (parallel groove clamp, drainage plate) all adopts the device clamp of 2 connecting bolts, need detect bolt torque value and come with torque wrench the contact reliability of control connection node. the assembling of having mentioned especially overhead transmission line shaft tower uprightly requires connecting bolt fastening one by one, the upright requirement of assembling of shaft tower is used torque wrench in the time just filling, connecting bolt should be all once fastening again after the assembling uprightly of overhead transmission line shaft tower, after stringing, also should tighten up once and check torque value, the tightening torque of bolt must not be less than setting.
Existing torque wrench is assembled when upright and is fastenedly connected bolt at steel tower, in use has following problem:
(1) realize the apparatus structure complexity of moment of torsion control, dial type torque wrench needs frequently to change pulloverly, 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 larger, uses inconveniently in the narrow little space of tower material, can not fit the requirement of tightening of applying multi-standard bolt.
(4) minor impact when install at scene easily makes torque values distortion.
(5) existing torque wrench is accurate apparatus, and instrument cost is higher.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of survivor of a murder attempt's torque wrench, have simple in structure, easy to use, the feature that spanner torque value is easily observed.
For solving the problems of the technologies described above, technical solution adopted in the utility model 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 below 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.
The further improvement that the utility model is done is: 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, the longitudinal close-packed arrays of spring steel wire is in sleeve pipe, the periphery at described sleeve pipe both ends is polygon through extruding cross section, be provided with respectively sleeve 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 on handle middle part, and two screw fastenings are passed through on cushion block in the upper end of unsettled pointer arm.
The beneficial effect that adopts 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 that multi-strand spring steel wire from broken lot occurring when stressed, 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 from use occurring spanner and pull tail distortion.
Five, spanner positive direction is used or uses in the other direction, all can observe directly torque value, and intuitive is strong. The utility model is easily manufactured, and impact resistance easy to use can accurately be observed torque value, can reduce labour intensity, improves efficiency of construction, reduces construction cost.
