Abstract
The utility model relates to a track screw oil coating and fixed torque wrench which is special tool for fastening or loosening bolts and coating oil on bolts. A fixed torque and a hand piston pump are assembled together. When a bolt is fastened, a torque is transferred through an inclined surface of a ladder-shaped jaw clutch; when the fixed torque is exceeded, an upper clutch lift along the inclined surface to trip the clutch. When the bolt is loosened, the torque is transferred in a permitted range for strength through a straight surface of the clutch in order to loosen the bolt. When fastening and loosening a bolt, the bolt is coated with oil by the hand piston pump. The utility model has the main advantages that the wrench has light weight, and saves torque testing tool and operation time, and manual oil-coating tool and time.
Description
The utility model relates to a kind of railway track maintenance activity and is used to tighten, and unclamps track screw spike nut, and the while is to the special tool of bolt thread portion oiling.
During present domestic railroad track maintenance, be used to tighten or when unscrewing the operation of railway spike nut, the special wrench of use is a kind of T jacket barrel spanner, or more backward plate spanner.Its moment of torsion can not be controlled, and when needs definite value moment of torsion, after tightening nuts, re-uses and surveys dial torque wrench mensuration.When tightening or unscrew nut, want another set of instrument to the bolt part oiling.Increase flow chart and equipment, be not suitable for maintenance activity.
The purpose of this utility model is the shortcoming that overcomes existing spanner, is coated with anti-corrosion oil when providing a kind of and tighting a bolt (or unscrewing bolt) synchronously.Provide a kind of moment of torsion to set, threading off automatically at the spanner that tights a bolt when reaching definite value becomes the instrument of idle running.When unscrewing nut, spanner unscrews nut in the scope that intensity allows.
The technical solution of the utility model is achieved in that what an a kind of spanner that has an adjustable setting valve moment of torsion that the ladder type dental clutch forms and a cover hand piston pump and oil piping system were formed.The even twisting moment spanner is by drive link lower end and last power-transfer clutch weld together, last clutch is by the top compression spring that is equipped with, the setting of spring lid, following power-transfer clutch and screw cap sleeve are linked together, these other parts are contained in the hollow garden shape gear box, L type spanner handle is equipped with in the upper end of last clutch, the pressure of adjusting compression spring increases or reduce moment of torsion to be made and reaches fixed value, the plunger pump assembly is to be welded in transmission to burn-on, anti-corrosion oil passes through transport pipe during oiling, unidirectional cutting down annotated oil in the centre hole of the centre hole of power-transfer clutch up and down and wrench socket top, and anti-corrosion oil is coated onto on the track bolt.
The utility model compared with prior art has when tighting a bolt and can set moment of torsion, and spanner is threaded off automatically and become idle running when moment of torsion reaches definite value.The adjustable size seamless of the moment of torsion spring that contracts is finished.Oiling on bolt simultaneously when tightening and unscrew bolt.In existing service tools, also do not use this spanner.When unscrewing bolt, face contact directly with the ladder type power-transfer clutch, pine is unloaded bolt in the intensity allowed band.The utility model volume is little, in light weight, has saved the measuring tool that a cover wiper and a cover are measured moment of torsion.Use the utility model to make former three process become one procedure, saved production time.
Now describe the utility model the best in conjunction with the accompanying drawings in detail and execute routine accompanying drawing master pseudosection

Bolt oiling operation: unload bolt oiling simultaneously tightening with pine.Bolt collar (1) is enclosed within on the nut of track, and finger connects the plunger (10) of lower plunger pump, and spring (9) is compressed, and the unidirectional steel ball that cuts down (7) is pressed in and cuts down on the mouth, and the path of past oil (13) is closed.At this moment the oil in the oil pump is compressed, toward current downflow, push steel ball (5) to below along transport pipe (17), spring (19) is compressed to cut down and mouthful opens, pressure oil is sent in the centre hole of power-transfer clutch (20) and following power-transfer clutch (2), annotates the screw cap sleeve upper end oil is coated onto on the track bolt.Spring when the finger by embolism unclamps (9) is with embolism (10) jack-up, spring this moment (19) is pressed in steel ball (5) and cuts down a mouthful oil of going up the outflow of blocking-up transport pipe, and steel ball (7) compression spring (8) at this moment, anti-corrosion oil (15) in the fuel tank (13) is drawn onto in the oil pump, when the oil level of fuel tank (13) descends, when air pressure is lower than barometric pressure in the fuel tank, unidirectionally cuts down unidirectional the cutting down of steel ball (12) compression spring (11) and open to mend air.
Operation tights a bolt: bolt collar (1) is enclosed within on the track bolt after the oiling, holding spanner handle (14) is rotated in a clockwise direction, by drive link (16) power is passed to power-transfer clutch (20), last power-transfer clutch is the ladder type dental clutch with following power-transfer clutch (2), make power-transfer clutch inclined-plane A produce friction force by compression spring (4), when spanner (14) moment of torsion during less than friction force, the following rotation with spanner handle from device (2) and screw cap sleeve (1) tightened nut.When the power of spanner handle (14) during greater than friction force, last power-transfer clutch (20) rises along inclined-plane A power-transfer clutch is threaded off, and at this moment reaches moment of torsion definite value bolted and finishes.
The bolt pine is unloaded operation: screw cap sleeve (1) is enclosed within holds spanner handle (14) on the nut and rotate in the counterclockwise direction, go up power-transfer clutch (20) by drive link (16) and face directly power is passed to down power-transfer clutch (2) and screw cap sleeve (1) unloads the track bolt pine in the scope of intensity permission.
The adjustment of moment of torsion: finish by setting of spring lid (18), compression spring (14) strengthened the dropout moment of torsion when setting of spring lid was just changeing, and moment of torsion is reduced.Setting range 0～200 newton meter.
