Abstract
The invention discloses a kind of telescopic driving wheel structures, telescopic driving wheel structure is applied on the mechanical trolley run on track, mechanical trolley is set to shuttle under the chassis of subway traveling, sensor will be installed during actual travel on driving wheel structure, barrier is met when sensor detects rail signal, wheel retracts avoided rapidly, when wheel is after barrier, sensor receives the stretching of signal wheel, this set telescopic driving wheel structure can allow small rail car change wheel wheelspan, to get rid of interorbital away from constraint realize avoidance in orbit traveling.
Description
Technical field
The present invention relates to a kind of telescopic driving wheel structures.More particularly to it a kind of applies in railway underground railway track Shuttling trolley
On telescopic driving wheel structure.
Background technique
Applying the mechanical trolley on railway on all kinds of tracks at present is travelled on accessible track, due to existing
Mechanical trolley in technology is limited by wheel, and cannot achieve evacuation when there is barrier on track, it is even more impossible to realize in train
Or the traveling that shuttles under the chassis of subway carries out safety check operation, this is because mechanical trolley in the prior art is in the design process
The width of wheelspan can not be changed, trolley can only be designed according to the developed width of track, and when the mechanical trolley encounters barrier
Wheel normally travel in body construction does not have contractile function, and mechanical trolley is caused to run on the railroad track very in this way
It is not convenient.
Summary of the invention
According to problem of the existing technology, the invention discloses a kind of telescopic driving wheel structures, specifically include: bearing
Seat, is provided with splined shaft across bearing block, one end of the splined shaft is connected with wheel, and the inside of the bearing block is set side by side
Deep groove ball bearing there are two setting, is provided with rotary sleeve, one end of the rotary sleeve and spline across two deep groove ball bearings
It is connected, the spline and splined shaft form spline pair；The other end of the rotary sleeve is connected with synchronous pulley, the spline
The other end of axis is connected with bearing, and the bearing is fixedly connected on link block, and one end of the link block is connected with sliding block
Connect, the other end is connected with hydraulic cylinder, the sliding block is connected with guide rail, and the guide rail and bearing block are fixed on bottom plate.
The spline is inlayed and passes through rotary sleeve setting.
The hydraulic cylinder is fixedly connected on bearing block.
By adopting the above-described technical solution, a kind of telescopic driving wheel structure provided by the invention, which is answered
It uses on the mechanical trolley run on track, so that mechanical trolley is shuttled under the chassis of subway traveling, actual travel process
It is middle that sensor will be installed on driving wheel structure, barrier is met when sensor detects rail signal, wheel retracts rapidly
It is avoided, when wheel is after barrier, sensor receives the stretching of signal wheel, this set telescopic driving wheel structure can allow
Small rail car changes the wheelspan of wheel, thus get rid of interorbital away from constraint realize avoidance in orbit traveling.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this

Specific embodiment
To keep technical solution of the present invention and advantage clearer, with reference to the attached drawing in the embodiment of the present invention, to this
Technical solution in inventive embodiments carries out clear and complete description:
A kind of telescopic driving wheel structure as depicted in figs. 1 and 2, including bearing block 50, are provided with across bearing block 50
Splined shaft 51, the bearing block 50 are fixed on bottom plate 63, and one end of splined shaft 51 is connected with wheel 52.In bearing block 50
Inside is arranged side by side there are two deep groove ball bearing 53, and rotary sleeve 54 passes through two deep groove ball bearings 53 and is arranged, rotary sleeve 54
One end be connected with spline 55, spline 55 and splined shaft 51 form spline pair.The characteristics of spline pair is spline 55 in rotation
The rotation of splined shaft 51 is driven simultaneously and splined shaft 51 can move in spline 55.It is connected in the other end of rotary sleeve 54
Synchronous pulley 56.Being rotated by synchronous pulley 56 drives splined shaft 51 to rotate, and the other end of splined shaft 51 is connected with bearing 57,
Bearing 57 is fixedly connected on link block 58, and one end of the link block 58 is connected with sliding block 59, the other end and hydraulic cylinder 60
It is connected.Sliding block 59 is connected with guide rail 62, and guide rail 62 is fixed on bottom plate 63.Based on above-mentioned transmission and connection relationship when hydraulic
It just will drive splined shaft 51 when cylinder 60 stretches and wheel 52 stretch together, to sum up a whole set of telescopic driving wheel structure is in the same of rotation
When quick-expansion also may be implemented.
Further, spline 55 is inlayed and passes through rotary sleeve 54 and is arranged, and prevents play with the locking of lock sleeve 64, guarantees
Structurally stable carry out power transmission.
Further, the hydraulic cylinder 60 is fixedly connected on bearing block 50.
A kind of telescopic driving wheel structure disclosed by the invention is worked in coordination in the mechanical structures such as hydraulic cylinder 60 and spline pair
Automatic contraction with lower realization wheel is driven, which can be applied to and be walked on mechanical trolley in orbit,
Guarantee mechanical trolley traveling accessible in orbit.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
