Description
Technical field
A kind of single track rotary turnout of the utility model, belongs to underground coal mine monorail crane rail technical field.
Background technology
Single track rotates road when locomotive passes through rotation rail at present, and up and down the four of the main shaft at in-between position and rotation rail both ends
Point should stress simultaneously, at this moment rotation rail whole part be in " cross position " state, but in practical application, due to its mismachining tolerance and
Rigging error can not possibly be zero, thus, in real work, always the end of side where rotation rail weight bearing area and main shaft simultaneously by
Power, and the rotation rail other side does not stress then.In this way, when locomotive continues through rotation rail, main shaft will be made by alternation moment of flexure
With so that bend and off-axis, and the stress of rotation rail then when and be similar to cantilever beam, when and be similar to simply supported beam,
So that the case where main shaft bending, fracture and bending track deform frequent occurrence, is badly in need of a kind of new structure, to improve its stress.
Utility model content
The utility model overcomes the shortcomings of the prior art, provides a kind of single track rotary turnout, main shaft is made not hold
By the power of any direction, the stability of transition is improved, while also improving reliability and the service life of entire rotation system.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of single track rotary turnout, including
Transition, sleeve, lift cylinder, rotating shaft, bearing and support base, the rotating shaft are vertically arranged in by bearing on support base,
And the upper end of the rotating shaft is connect with support base, the lower end of the rotating shaft by sleeve connection in transition, the sleeve
Lift cylinder is provided between support base, the cylinder body of the lift cylinder is connected on support base, the work of the lift cylinder
Stopper rod is connected on sleeve, is promoted transition by lift cylinder and is detached from trapped orbit, and the support base is provided with driving device,
The driving device is for driving rotating shaft to rotate.
The transition and trapped orbit junction end face are obliquely installed, and lower end is inclined outwardly, the transition and solid
The upper end for determining rail connection has been provided projectingly positioning card key, and the lower end of the transition and trapped orbit junction is provided with recessed
Slot, the positioning card key and groove respectively be correspondingly arranged on trapped orbit structure matching clamping.
The driving device is motor, or is oil cylinder.
The utility model has an advantageous effect in that compared with prior art：The utility model remakes above and below without main shaft
Sliding motion, only transition and sleeve move up and down so that operating force greatly reduces.To greatly improve the reliability of operation
And significantly reduce cost.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the connection diagram of transition and trapped orbit in the utility model.
In figure：1 it is transition, 2 be sleeve, 3 be lift cylinder, 4 be rotating shaft, 5 be bearing, 6 be support base, 7 is fixed
Track, 8 be positioning card key, 9 be groove.
Specific implementation mode
As shown in Figure 1 and Figure 2, a kind of single track rotary turnout of the utility model, including transition 1, sleeve 2, lift cylinder 3, return
Shaft 4, bearing 5 and support base 6, the rotating shaft 4 are vertically arranged in by bearing 5 on support base 6, and the rotating shaft 4
Upper end is connect with support base 6, and the lower end of the rotating shaft 4 is connected to by sleeve 2 in transition 1, the sleeve 2 and support base 6
Between be provided with lift cylinder 3, the cylinder body of the lift cylinder 3 is connected on support base 6, the piston rod of the lift cylinder 3
It is connected on sleeve 2, transition 1 is promoted by lift cylinder 3 and is detached from trapped orbit 7, the support base 6 is provided with driving dress
It sets, the driving device is for driving rotating shaft 4 to rotate.
The transition 1 and 7 junction end face of trapped orbit are obliquely installed, and lower end is inclined outwardly, the transition 1 with
The upper end of 7 junction of trapped orbit has been provided projectingly positioning card key 8, and the transition 1 and the lower end of 7 junction of trapped orbit are arranged
Fluted 9, the positioning card key 8 and groove 9 respectively with structure matching clamping is correspondingly arranged on trapped orbit 7.
The driving device is motor, or is oil cylinder.
The utility model makes rotating shaft only play the turning effort of transition, when locomotive passes through transition, completely by rotation rail two
4 positioning card key positioning at end and stress, and main shaft does not stress then, is completely in free state, to thoroughly solve above-mentioned ask
Topic.
Transition is mounted on by sleeve below rotating shaft in the utility model, can be rotated synchronously with main shaft, sleeve can carry
Under the action of oil-lifting jar, the axial direction along rotating shaft slides up and down；Rotating shaft is in motor（Or oil cylinder）Driving under it is rotatable certain
Angle.The end face of transition is an angled section, and upper end is inclined outwardly, and there is horizontal positioning card key outstanding in upper end, with trapped orbit
Groove above end face is corresponding；The end face of trapped orbit is also angled section, and lower end is inclined outwardly, and lower end has horizontal outstanding
Card key is positioned, it is corresponding with the groove below transition track end face.
The use process of the utility model：
When needing switching track, lift cylinder is operated, first, makes sleeve that transition be driven to translate up certain altitude, makes to turn
Rail is detached with trapped orbit, then, is operated rotating mechanism, is turned over certain angle, then operate lift cylinder and move down, make transition
It is combined with trapped orbit.
Since the combination end face of transition and trapped orbit is inclined-plane and has positioning card key positioning, if transition is by downward
When power, downward power can be passed into two trapped orbits by track end face and card key, and main shaft is not subject to any direction
Power, improves the stability of transition, while also improving reliability and the service life of entire rotation system.
Upper and lower sliding motion is remake since the utility model is not necessarily to back axis, only transition and sleeve moves up and down so that behaviour
Greatly reduce as power.Thus before transition is turned round, mechanical fork can be used to be manually operated, and save hydraulic pressure（Pneumatically）Operating system and
Rack pinion system, to greatly improve the reliability of operation and significantly reduce cost.
The utility model is explained in detail above in conjunction with embodiment, but the utility model is not limited to above-mentioned implementation
Example, within the knowledge of a person skilled in the art, can also be in the premise for not departing from the utility model aims
It is lower that various changes can be made.
