Description
The utility model belongs to railway maintenance, maintenance field of mechanical technique, is specifically related to a kind of gasoline engine driving double end nut degree of tightness machine that the sleeper nut is carried out fastening and loosening operation.
The used sleeper nut degree of tightness machine of domestic existing railway maintenance mainly contains two kinds, and a kind of is the single head impact type, and another kind is the quiet moment of torsion formula of double end.
Single head nut degree of tightness machine, the clamp load torque control of nut is bad, causes whole piece rail and pressure to change greatly, does not reach job requirement.Because working speed height, impact force are big, cause fault rate height, noise big, and move inconvenient, workman's manipulation strength is big.
Existing bullhead nut degree of tightness machine, the moment of torsion controlling organization designs below reduction box, and promptly underneath type causes the machine gravity height, and it is extremely unreliable to work together.Because no car is very difficult moving of ground, because no aiding support makes that the walking on railway is also very difficult.
At the problem that prior art exists, the purpose of this utility model is to provide a kind of more reasonable structural design, screws the moment of torsion high conformity, noise is low, fault rate is low, the sleeper nut degree of tightness machine of easy and simple to handle, conveniently moving.
Technical solution of the present utility model is as follows:
Sleeper nut degree of tightness machine comprises motor, reduction box, steering tiller, moment of torsion controlling organization, operating mechanism.The power output of motor connects reduction box, establishes steering tiller on the reduction box, and the central gear of reduction box output connects the moment of torsion controlling organization.Described moment of torsion controlling organization is located at the sleeve gear top with the engagement of reduction box central gear, and operating mechanism places its below.The sleeve gear of described moment of torsion controlling organization is connected with following moment of torsion sleeve key, following moment of torsion sleeve again with the clutch of last moment of torsion socket teeth, last moment of torsion sleeve is connected with the spline axle key, the lower end key connection work sleeve of splined shaft, the splined shaft upper end is established the moment of torsion control spring and is regulated nut, and spring is installed in to be regulated between nut and the last moment of torsion sleeve.
The moment of torsion controlling organization of this degree of tightness machine is symmetrical arranged two covers, and central gear meshes with left and right sleeve gear simultaneously.Operating mechanism is made up of slide plate, shift fork and support bar, spring, slide plate branch sleeve and shift fork, the shift fork head is connected the support bar two ends, between establish spring, shift fork connects control stick.This degree of tightness machine complete machine is arranged on the walking car of height guardrail.At the bottom of the walking car nylon wheel and aiding support are installed.Motor is selected the gasoline engine of 5.5HP-6HP for use.
The course of work of this machine is as follows:
The power that spreads out of by gasoline engine, behind reduction box, transmission is through central gear, pass to left and right sleeve gear respectively by its power again, sleeve gear drives the empty following moment of torsion control sleeve that is enclosed within on the splined shaft, drives by gear clutch and goes up moment of torsion control sleeve, drives splined shaft again, by splined shaft drive work sleeve, finally finish the fastening and loosening of nut by the work sleeve.
The moment of torsion controlling organization realizes that the step of control is: because splined shaft is to be driven by last moment of torsion control sleeve, and go up moment of torsion control sleeve is to be driven by gear clutch by following moment of torsion control sleeve, their disengagement moment then becomes the maximum clamp load torque of nut, and the disengagement moment size between them is by the decision of the tight power size of giving of moment of torsion control spring.The upper design of splined shaft becomes square toes, blocks square toes with spanner during adjustment, regulates nut with another spanner adjustment, can adjust the tight power of giving of moment of torsion control spring, the final control that realizes moment of torsion.
Operating mechanism is by the sliding up and down of slide plate, shift fork realization work sleeve, and finishes the fastening and loosening of nut.Also designed disengaging gear in emergency circumstances in addition: stuck as work sleeve and nut when unexpected situation takes place, only need knock the control stick bottom this moment, make shift fork compression spring, form shift fork and slide plate and break away from, the sleeve of then working can break away from splined shaft, and complete machine can be moved away from track.
The advantage of this machine is:
1. simple in structure, compact, easy to operate: this machine will move on the moment of torsion controlling organization, with the operating mechanism underlying, whole center of gravity is lowerd, and stability is better, and is convenient to regulate moment of torsion, more convenient operation.
2. this structure screws the moment of torsion high conformity, and fault rate is low.
3. utilize gasoline engine to do power, noise is low, improves the safety of work.
4. adopt the walking car of high-low type, be convenient to promote to move, aiding support cooperates with car front and back nylon wheel, and this machine is moved on rail like a cork, uses more convenient.
Below in conjunction with drawings and Examples the utility model is described further:
