Description
Technical field
The utility model belongs to down-hole engineering equipment technical field, is specifically related to a kind of steering handwheel for transport vehicle in tunnel.
Background technology
Down-hole, due to the restriction of drift section, causes down-hole mostly to be unidirectional track, when putting equipment, due to the mistake of device orientation during the entrucking of ground, has to force staff to lift by crane equipment, break-in, and complicated operation, exists potential safety hazard.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of steering handwheel for transport vehicle in tunnel.
For achieving the above object, the technical solution of the utility model is achieved in that
The utility model embodiment provides a kind of steering handwheel for transport vehicle in tunnel, this steering handwheel comprises: top board, base plate, track, described top board is arranged the track of intersecting parallels, described top board bottom centre arranges center shaft, described center shaft is located in the sleeve of base plate top center, is provided with several bearings between described top board and base plate.
In such scheme, four opening directions of described track are corresponding with the main orbit of four direction.
In such scheme, several bearings described be evenly arranged in the center of base plate for the center of circle circumferentially.
In such scheme, the position of described top board bottom surface respective carter opening is provided with for the depression with bearing fit.
Compared with prior art, the beneficial effects of the utility model:
The utility model can, complete the direction of transport vehicle in orbit on 90 °, 180 ° and rotate, saved labour power, decreased potential safety hazard.
Accompanying drawing explanation
Fig. 1 provides a kind of structural representation of the steering handwheel for transport vehicle in tunnel for the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model embodiment provides a kind of steering handwheel for transport vehicle in tunnel, as shown in Figure 1, this steering handwheel comprises: top board 2, base plate 5, track 1, described top board 2 is arranged the track 1 of intersecting parallels, described top board 2 bottom centre arranges center shaft 6, described center shaft 6 is located in the sleeve 3 of base plate 5 top center, is provided with several bearings 4 between described top board 2 and base plate 5.
Four opening directions of described track 1 are corresponding with the main orbit of four direction.
Several bearings 4 described be evenly arranged in the center of base plate 5 for the center of circle circumferentially.
The position of described top board 2 bottom surface respective carter 1 opening is provided with the depression for coordinating with bearing 4, like this, after rotation, top board 2 can be made to fix, guarantee passing through of transport vehicle safety and stability.
Embodiment:
Utilize oxygen welding cutting that steel plate is cut into toroidal, even 12 bearings on base plate 5, at steel plate center weld sleeve 3, for being connected with top board 2 times square steel tubes, reach the object that top board 2 moves around center shaft 6, the track 1 that installation and main orbit are closely connected on top board 2, when needs guide-car, carries out rotating.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
