Background
The rail in the mine rail transportation system is basic equipment for ensuring reliable ore transportation, the state of the rail is extremely important for the normal operation of electric locomotives and mine cars, the rail gauge of the underground rail transportation system is mainly 762mm at present, the specification and model are respectively 38kg/m and 30kg/m, and the rail joints are connected through common fishplates and fishtail bolts. When part of the rails are replaced, the rails with the sizes of 30kg/m and 38kg/m are connected, the rails with different types and specifications are different in size, corresponding fishplates are also different in size, if the joints are not firmly connected, the risk of vehicle derailment can be caused, meanwhile, the wheels are worn greatly, the ore drawing time is seriously influenced, and the annual rail ore drawing task amount cannot be safely and efficiently completed.
Disclosure of utility model
The utility model aims to provide a connecting device suitable for rails of different specifications of a mine rail transportation system, and solves the problems of labor consumption, low efficiency, unstable connecting positions and large connecting gaps in the connecting process of the rails of different specifications.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
The connecting device comprises a positioning base plate and a connecting clamping plate, wherein the positioning base plate and the connecting clamping plate are arranged at the joint of a first rail and a second rail which are different in specification and model, the positioning base plate is in a step shape, one end of the positioning base plate is supported and placed with the first rail, the other end of the positioning base plate is supported and placed with the second rail, and the top surfaces of the first rail and the second rail are flush after being supported and placed; the connecting clamping plate is in a broken line shape, one end of the connecting clamping plate is connected with the side part of the first track, the other end of the connecting clamping plate is connected with the side part of the second track, and the track gauges of the first track and the second track after the connecting clamping plate are connected are equal.
The utility model has the following beneficial effects:
Through implementation of the technical scheme, rail connection of different underground specifications is realized, labor intensity of workers is greatly reduced, production stopping construction time is shortened, and production efficiency is improved; secondly, the problem that the connecting plates are not integral in the connecting process of different rails is solved, the connecting plates of the same model cannot be suitable for connecting the rails of different models due to the fact that the rail parameters and the shapes of the different rails are different, the problem is solved by the special-shaped connecting plates, the waist width, the positions and the number of bolt holes of the connecting plates can be corresponding to the connecting plates, and the tightness and the firmness of rail joints are guaranteed; the problem that the heights of the rails of different specifications are different is solved, the light rail is lifted through the positioning base plate, the top surface of the rail is positioned on the same horizontal plane, the flatness of the rail joint is guaranteed, meanwhile, four track nail holes are formed in two ends of the positioning base plate respectively, the positioning base plate and the sleeper are more firmly fixed, and the potential safety hazard of displacement of the positioning base plate is eliminated.

Detailed Description
As shown in fig. 1-3, a connecting device suitable for rails of different specifications and models of a mine rail transportation system comprises a positioning base plate 1 and a connecting clamping plate 2, wherein the positioning base plate 1 and the connecting clamping plate 2 are arranged at the joint of a first rail 3 and a second rail 4 which are different in specification and model, the positioning base plate 1 is in a step shape, one end of the positioning base plate is supported and placed with the first rail 3, the other end of the positioning base plate is supported and placed with the second rail 4, and the top surfaces of the supported and placed first rail 3 and second rail 4 are flush; the connecting clamping plate 2 is in a zigzag shape, one end of the connecting clamping plate is connected with the side part of the first track 3, the other end of the connecting clamping plate is connected with the side part of the second track 4, and the track gauges of the first track 3 and the second track 4 after the connecting clamping plate are equal.
The two ends of the positioning backing plate 1 are provided with spike holes, and the positioning backing plate is connected with a sleeper 7 through spikes 5 inserted into the spike holes. The two ends of the connecting clamping plate 2 are respectively provided with through holes, and the connecting clamping plate is respectively connected with the first track 3 and the second track 4 through connecting bolts 6 inserted into the through holes at the two ends.
In specific application, taking the connection of a 30kg/m track and a 38kg/m track as an example, the sleeper 7 is taken as a track foundation to bear the track; the locating backing plate 1 is placed above the sleeper, the first track 3 (30 kg/m) and the second track 4 (38 kg/m) are placed on the locating backing plate 1, the two tracks are guaranteed to be in the same plane, the track gauges of the two different tracks are guaranteed to be consistent, then the two tracks are connected through the connecting clamping plate 2, one end of the connecting clamping plate 2 is connected with the second track 4 (38 kg/m), the other end of the connecting clamping plate 2 is connected with the first track 3 (30 kg/m), the two connecting ends are rectangular, and the two connecting ends can be respectively embedded with the waists of the tracks of 38kg/m and 30 kg/m.
