Description
Technical field
The utility model belongs to underground work technical field, and in particular to a kind of underground orbit direction converter.
Background technique
Currently, rail roadway construction not only needs laying a switch, and need to smear angle and setting when encountering the steering of friendship fork
It gives another the right of way field, if intersecting the tunnel (general vertical friendship trouble person is in the majority) of trouble with rail travel tunnel compared with long, freight volume is big, with top
Method is conducive to improve conevying efficiency, if intersect with rail travel tunnel branch off tunnel is shorter, freight volume very little, still use more than
Method carry out rail construction, there is laying a switch,
It smears angle and the excessively high problem of a cost of giving another the right of way is set, be unfavorable for economic benefit.
Utility model content
The purpose of the utility model is to provide a kind of underground orbit direction converters, are needed with solving the prior art in underground
Laying a switch smears angle and setting is given another the right of way field, the excessively high problem of shorter for length, freight volume very little construction tunnel cost.
In order to achieve the above object, the technical solution adopted in the utility model are as follows:
A kind of underground orbit direction converter, including fixed structure, rotational structure and position limiting structure, the fixed structure packet
The steel pipe for including concrete layer and being vertically installed in concrete layer；The rotational structure includes the shaft for being set to steel pipe top,
Bolt is arranged in the top of shaft, and the periphery of shaft is successively arranged bearing and turntable from bottom to top, and pressing plate, pressure is arranged in the top surface of shaft
The catercorner length of plate is greater than the diameter of shaft, and the nut that the top surface setting of pressing plate cooperates with bolt is used to fix, on turntable with
The center of circle is that one group of rail being parallel to each other is arranged in axial symmetry；The lower end of the position limiting structure is set in concrete layer, upper end with
The periphery of turntable is close but does not contact.
At least one dowel hole is set on the turntable.
The positioning pin fixation hole of setting and dowel hole on same circumferential projection face on the concrete layer.
The both ends of the rail are located at except the circumference of turntable.
Backing plate is arranged at the top of the steel pipe, the top surface of backing plate is in contact with the bottom surface of shaft and bearing.
The bearing is radial thrust bearing set.
In the same plane, the top surface of bearing connects with the bottom surface of turntable for the bottom surface of the bearing and the bottom surface of shaft.
The position limiting structure is the reinforcing bar being vertically installed in concrete layer.
The pressing plate is square, and the side length of pressing plate is not less than the diameter of shaft.
The utility model having the beneficial effect that compared to the prior art
The utility model makes the track transporting tools such as mine car free in narrow underworkings using rotational structure
Rotation drive to mine car etc. can from track directly on rotational structure using the design of shaft, turntable and rail and then rotate, from
The direction of needs is driven towards on the track of opposite side；Setting position limiting structure prevents turntable from turning over docking location, and passes through position limiting structure, determines
Position pin hole and corresponding positioning pin fixation hole make turntable by limitation direction, consequently facilitating rail and actual needs direction (one
As be vertical direction) orbital docking.
Using the utility model, it is not necessary that the bend at construction fork is arranged in underground and smears angle, do not have to laying a switch and bending track,
The expense that mine builds project amount and laying a switch and bending track is saved, the economic benefit of small-scale engineering is improved.

Specific embodiment
The utility model is described further with reference to the accompanying drawings and detailed description.
As shown in the picture, a kind of underground orbit direction converter, including fixed structure, rotational structure and position limiting structure 10,
Fixed structure includes concrete layer 1 and the steel pipe 2 that is vertically installed in concrete layer 1；Rotational structure includes being set to the top of steel pipe 2
Bolt 4 is arranged in the top of the shaft 3 at end, shaft 3, and the periphery of shaft 3 is successively arranged bearing 5 and turntable 6, shaft 3 from bottom to top
Top surface pressing plate 7 is set, the catercorner length of pressing plate 7 is greater than the diameter of shaft 3, what the top surface setting of pressing plate 7 cooperated with bolt 4
One group of rail 9 being parallel to each other is arranged by axial symmetry of the center of circle on turntable 6 for fixing in nut 8；The lower end of position limiting structure 10 is set
It is placed in concrete layer 1, upper end is close with the periphery of turntable 6 but does not contact.
At least one dowel hole 11 is set on the turntable 6.
Setting and positioning pin fixation hole 12 of the dowel hole 11 on same circumferential projection face on the concrete layer 1.
