Description

Technical Field

[0001] The invention relates to the technical field of mine track construction, and in particular to a mine track calibrator and a use method thereof. Background Art

[0002] Some existing mine transportation in my country mainly adopts belt and rail transportation. At present, the reverse centerline method is used for track installation in the tunnel. The reverse centerline method is to reverse the line from the line point given by ground survey to confirm the laying position of the track. The reverse centerline method is used to determine the front and rear direction and flatness of the track extension so that the centerline of the track coincides with the centerline of the tunnel, ensuring the accurate position of the track in the tunnel and avoiding deviation or skew. However, the reverse line requires the cooperation of multiple people. One person stands at the line point position for a long time to direct the rear road repair personnel to adjust the laying position of the track by means of three points in a straight line. Due to the distance problem, at least three rear road repair personnel and line watchers are required to cooperate, one person directs, and the other two adjust the track. The process is cumbersome and the error is large. Summary of the invention

[0003] The embodiment of the present invention provides a mine track calibrator and a method of using the same, which has the technical effect of improving the accuracy and efficiency of track installation in a tunnel.

[0004] On one hand, the present invention discloses a mine track calibrator, which adopts the following technical solution: A mine track calibrator comprises a main frame, a level and an infrared laser pointer.

[0005] Furthermore, a brake assembly is provided on the bottom plate to prevent the first wheel axle from rotating.

[0006] Furthermore, the brake assembly includes a brake block, a connecting rod and a connecting block. The brake block is located between the first wheel axle and the base plate. The bottom of the connecting rod is fixed to the brake block, the top of the connecting rod passes through the base plate and is fixed to the connecting block. A spring is fixed between the connecting block and the top plate, and the spring is sleeved on the connecting rod. A pressure block is rotatably connected to the base plate, and the pressure block can press against the connecting block.

[0007] Furthermore, a mounting rod is fixed on the bottom plate, one end of the pressing block is rotatably connected to the mounting rod, a locking nut is threadedly connected to the mounting rod, and the pressing block is located below the locking nut.

[0008] Furthermore, limiting blocks are fixed on both sides of the moving block, a sliding block is fixed on one side of the limiting block close to the guide rail, and a sliding groove for the sliding block to slide is provided on the guide rail.

[0009] Furthermore, a clamping bolt is provided on the moving block, and the clamping bolt can fix the position of the moving block on the guide rail.

[0010] On the other hand, the present invention also discloses a method of use, comprising the following steps: S1. Place the main frame at the position of the constructed track, use an infrared laser pointer to illuminate the front and back to determine the direction of the main frame facing the constructed track, use a level ruler to drive the main frame to be horizontal, and the width of the two first wheels is the width of the constructed track; S2, after the main frame is adjusted to be stable, the main frame is fixed by using a brake assembly, and then the track is laid according to the direction of the infrared laser pointing instrument (44); S3. After the track is laid, the operator holds the handle and pushes forward in the direction of track repair. By observing the distance between the two first wheels, it can be determined whether the track gauge is qualified. If it is unqualified, it will be adjusted immediately according to the wheel width; S4. While the operator is moving forward, observe the state of the bubble in the level ruler. If the bubble deviates to one side, it means that the track is uneven. Adjust the track until the bubble returns to the middle position of the level ruler. S5. When the gauge, direction and flatness of the tested track have met the standard requirements, the track section can be reinforced; S6. The operator pushes the main frame to the end of the fixed track to prepare for laying the next section of track, and then repeats the above steps.

[0011] Compared with the prior art, the present invention has the following technical effects: Compared with the method of determining the direction and flatness of the road repair by the reverse line, the device and method of the present invention only require one person to operate, which reduces the labor cost. The track is corrected by using an infrared laser pointer, and all indicators can meet the standard requirements.

The pressing block 26 is rotated to rotate it above the connecting block 23, and the pressing block 26 can be pressed against the connecting block 23.

[0019] When the calibrator needs to be stopped, the connection block 23 is pressed downward to compress the spring 24, so that the brake block 21 compresses the first wheel axle 14, thereby preventing the first wheel axle 14 from rotating. The pressing block 26 is rotated to make the pressing block 26 press against the connection block 23, thereby preventing the connection block 23 from moving upward.
