Claims

1. A pipe pig servicing device, characterized in that The system includes a maintenance trolley and a track located within a pipe tunnel. The track consists of two mirror-symmetrical U-shaped channel steels positioned in the tunnel, with their openings facing each other. The maintenance trolley includes a trolley body. Multiple pulleys are connected to each other at intervals on both sides of the lower end face of the trolley body along its length. Each pulley on one side is located within a U-shaped channel steel. Multiple guide wheels are also provided on both sides of the lower end face of the trolley body along its length, with each guide wheel located on the outer side of the two U-shaped channel steels and adjacent to their outer surfaces. The guide wheels roll along the outer surfaces of the U-shaped channel steels.

2. A device according to claim 1, characterised in that Multiple sets of steel plates are symmetrically arranged on the lower end surface of the trolley body relative to its longitudinal centerline. A bearing is installed on each set of steel plates, and the pulley is connected to both ends of the bearing.

3. A device according to claim 1, wherein On the lower end face of the trolley body, multiple sets of guide wheel shafts extending vertically downward are symmetrically arranged relative to its longitudinal centerline. The guide wheel shafts pass through the guide wheels and are rotatably connected to the guide wheels. A fixed steel plate is coaxially fixed to the upper end of the guide wheel shaft. A screw hole is opened on the steel plate. The steel plate is connected to the bottom plate of the trolley body by bolts.

4. A device according to claim 1, wherein The distance between the guide wheel and the outer side of the U-shaped channel steel is 1~3mm.

5. A device according to claim 1, wherein The difference between the thickness of the pulley and the inner width of the U-shaped channel steel is 1~2mm.

6. A device according to claim 1, wherein The maintenance trolley is also equipped with a braking device, which includes a right-angle lever. A threaded round steel bar is vertically connected to the lower end face of the horizontal bar of the right-angle lever. The threaded round steel bar and the vertical bar of the right-angle lever are located on both sides of the horizontal bar. An internally threaded ring is screwed onto the threaded round steel bar. The outer side wall of the internally threaded ring is fixedly connected to the inner side wall of the through hole on the bottom plate of the trolley body. The lower end face of the threaded round steel bar is opposite to the upper end face of the U-shaped channel steel bar.

7. A pipe running device according to claim 6, wherein A friction block is fixed to the lower end of the threaded round steel bar; a round tube is sleeved on the vertical rod of the right-angle lever, and both ends of the round tube are fixedly connected to the vertical rod through steel plates.

8. A device according to claim 1, wherein The tunnel maintenance device also includes drag-eye plates located at both ends of the trolley body along its length, and hand-cranked winches located on the bulkheads at both ends of the tunnel passage. The hand-cranked winches are connected to the drag-eye plates via steel wire ropes.
