Description

Technical Field

[0001] This utility model belongs to the field of mine rail transportation technology, specifically relating to an underground rail operation device. Background Technology

[0002] Rail transport, as the main mode of transportation in non-ferrous metal mines, is primarily responsible for transporting ore and waste rock underground. Due to the large workload, long rail transport routes, and crustal deformation during production, the rails wear out quickly during locomotive operation, leading to difficulties in handling worn rails and seriously affecting the safe and stable operation of locomotives.

[0003] Currently, when replacing old and new tracks underground, multiple people need to work together to lift the tracks onto a flatbed for transport. When encountering bends in the roadway with insufficient turning radii, maintenance personnel must repeatedly adjust the track distance and direction before transporting it to the replacement location. After installation, the old track is cut into three sections and recycled to a material recovery point. Due to the large workload, workers cannot simultaneously replace all severely worn tracks. Derailments caused by track wear during train operation pose a significant safety hazard to locomotive drivers and also reduce production efficiency. Therefore, transporting new tracks is difficult, and the labor intensity and risk factor for maintenance personnel in handling and adjusting tracks on bends are high. When replacing tracks, workers must transport both new and old tracks to the replacement and recovery locations, resulting in low transport efficiency and requiring multiple people working for extended periods, thus increasing manpower consumption. Utility Model Content

[0004] This utility model provides an underground track operation device to solve the problems of inconvenient transportation, the need for a large number of workers to carry and adjust the track, and low operation efficiency of existing track operation.

[0005] The technical solution of this utility model is: an underground track operation device, including a trolley, a through groove is opened in the support plate of the trolley, and fixed frames are symmetrically arranged on both sides of the through groove. A hand-operated hoist is arranged in the fixed frame, and a clamp is hung on the hand-operated hoist. The clamps on both sides hold the track.

[0006] As a further improvement of this utility model, a horizontal connecting rod is provided at the top of the fixed frame, and a lifting ring is movably connected to the bottom of the connecting rod, so that the hand chain hoist is connected to the lifting ring.

[0007] As a further improvement of this utility model, a connecting ring is provided at the bottom of the hand chain hoist, and a clamp fixing ring is connected to the connecting ring by bolts. The clamp is installed at the bottom of the clamp fixing ring.

[0008] As a further improvement of this utility model, the bottom of the trolley is provided with a sliding sleeve and multiple wheels. The wheels are connected to the sliding sleeve through a coupling, and the width between the wheels on both sides can be adjusted by the sliding sleeve.

[0009] As a further improvement of this utility model, the connecting shaft is provided with multiple limiting rings, and the sliding sleeve slides between the limiting rings.

[0010] The beneficial effects of this utility model are as follows: By installing a hand-operated hoist and grippers inside the trolley, the rail to be replaced is hoisted at the bottom of the trolley. Only a small number of workers are needed to follow the trolley and maintain its balance to complete the rail transportation. There is no need for secondary adjustments to the rail position in bends within the tunnel, avoiding repeated handling and adjustment of the rail. The newly replaced rail can be quickly put into operation. This utility model has a simple, stable, and reliable structure. The grippers prevent the rail from shifting laterally, facilitating transportation, effectively reducing the labor intensity of workers, improving the efficiency of rail operation, and ensuring the normal operation of the equipment, preventing accidents. It has extremely high practicality. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-2 As shown, an underground track operation device includes a trolley 1. A through groove 2 is provided in the support plate 10 of the trolley 1. Fixed frames 4 are symmetrically arranged on both sides of the through groove 2. A hand-operated hoist 6 is provided in the fixed frame 4. A gripper 8 is hung on the hand-operated hoist 6. The grippers 8 on both sides hold a track 9.

[0015] The top of the fixed frame 4 is provided with a horizontal connecting rod 3, and the bottom of the connecting rod 3 is movably connected to a lifting ring 5. The hand chain hoist 6 is connected to the lifting ring 5.

[0016] The bottom of the hand chain hoist 6 is equipped with a connecting ring 15, and a clamp fixing ring 7 is connected to the connecting ring 15 by bolts. The clamp 8 is installed at the bottom of the clamp fixing ring 7.

[0017] The bottom of the trolley 1 is provided with a sliding sleeve 13 and multiple wheels 11. The wheels 11 are connected to the sliding sleeve 13 through a connecting shaft 12. The width between the two wheels 11 can be adjusted by the sliding sleeve 13.

[0018] Multiple limiting rings 14 are provided on the connecting shaft 12, and the sliding sleeve 13 slides between the limiting rings 14.

[0019] In use, operate the hand chain hoists 6 on both sides to make the grippers 8 contact the track 9 on the ground, control the grippers 8 to hold the track 9, and then operate the hand chain hoists 6 on both sides to raise the track 9 until the track 9 is in contact with the bottom of the support plate 10 and the track 9 is in close contact with the trolley 1, so that it is not easy to shake and the track 9 does not touch the ground during transportation. Check whether the grippers 8 and the track 9 are clamped tightly to prevent the track 9 from moving left and right.

[0020] When encountering a point with insufficient turning radius, the inner side of wheel 11 will retract tightly against the inner side of the track. As the trolley 1 moves along the curved track, the connecting shaft 12 will automatically retract inward along the sliding sleeve 13, allowing the wheels 11 on both sides to adapt to the curved track, thus reducing the turning radius of the trolley 1 and facilitating passage. This allows the trolley to automatically adjust its position on the curve while moving along the track. After the turn is completed, the staff pushes the trolley 1 forward, with the outer side of wheel 11 slightly higher than the inner side. This causes the wheels 11 to move outward as they move forward until the inner sides of both wheels 11 are tightly against the inner side of the track, allowing the wheels 11 to move along the track's trajectory, ultimately completing the self-adjustment of the wheels 11 after the turn.
