[0007] Preferably, the front section track and rear section track are both composed of parallel arranged rail strips.
[0008] Replacement process: (1) replace operation side front end moving bearing: stop the roll -up machine in front of the limit block of rear section track, remove the connecting plate of front section track of operation side track, remove the front section track of operation side track, open locking oil cylinder, control roll -up machine to move forward to expose moving bearing, replace new moving bearing, roll -up machine is retreated to moving bearing enters rear section track, and front section track is returned.
[0009] (2) replace transmission side front end moving bearing: also stop the roll -up machine in front of the limit block of rear section track, remove the connecting plate of front section track of transmission side track, remove the front section track of transmission side track, open locking oil cylinder, control roll -up machine to move forward to expose moving bearing, replace new moving bearing, roll -up machine is retreated to moving bearing enters rear section track, and front section track is returned.
[0010] (3) replace operation side rear end moving bearing: after the coiler is parked at the limit block of the front section track, remove the connecting plate of the rear section track of the operation side track, remove the rear section track of the operation side track, open the locking oil cylinder, control the coiler to move backward to expose the moving bearing, replace the new moving bearing, move the coiler forward to the moving bearing into the front section track, and reinstall the rear section track.
[0011] (4) replace the transmission side rear end moving bearing: similarly, after the coiler is parked at the limit block of the front section track, remove the connecting plate of the rear section track of the transmission side track, remove the rear section track of the transmission side track, open the locking oil cylinder, control the coiler to move backward to expose the moving bearing, replace the new moving bearing, move the coiler forward to the moving bearing into the front section track, and reinstall the rear section track.
[0012] The utility model discloses obtained the beneficial effect:
[0013] (1) by dividing the operation side track and the transmission side track into the front section track and the rear section track, when replacing the front end moving bearing, the coiler is parked on the rear section track, which facilitates the coiler to move backward to remove the front section track, and similarly, when replacing the rear section moving bearing, the coiler is parked on the rear section track, which facilitates the coiler to move backward to remove the rear section track, creates the condition of exposing the moving bearing, realizes removing part of the track to complete the on-line quick replacement of the moving bearing, and improves work efficiency.
[0014] (2) the replacement device is simple in structure, and the device is used to replace the moving bearing and remove the equipment, and the belt coiler does not need to be lifted away from the original position by the travelling crane, compared with offline replacement, the time is greatly reduced, and especially when a moving bearing appears a problem in the production process, the replacement device can realize the replacement of a single moving bearing in a short time.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments.
[0022] like Figures 1-5 As shown, a quick-change device for the moving bearing of a belt conveyor includes a track and a sleeper 1. Rail supports 2 are fixed at intervals on the sleeper 1. The track includes a drive-side track 3 and an operating-side track 4. Both the drive-side track 3 and the operating-side track 4 are fixed to the rail supports 2 on the lower sleeper 1 via connecting plates 9. Both the drive-side track 3 and the operating-side track 4 include a front section track 5 and a rear section track 6. The end of the front section track 5 has a groove 7, and the beginning of the rear section track 6 has a protrusion structure 8. The groove 7 of the front section track 5 and the protrusion structure 8 of the rear section track 6 are fitted together. The beginning of the front section track 5 has a first limiting block 10. A second limiting block 11 is provided at the end of section track 6; both the front section track 5 and the rear section track are composed of two parallel rails 12; the front and rear sections track adopt a segmented design, which facilitates the disassembly of the track after the belt winder moves, provides conditions for replacing the moving bearing, realizes rapid replacement, shortens replacement time, reduces the impact of moving bearing damage on unit production, and saves costs; the replacement process involves less disassembly of the structure, and a single damaged moving bearing can be replaced, improving efficiency; the belt winder is limited by the first limiting block and the second limiting block to prevent the winder from derailing from the track and causing an accident.
[0023] After applying this replacement device, it is no longer necessary to remove accessories such as cylinder connecting pins, cables, hydraulic pipes, and tank chains. Less equipment needs to be removed. The entire belt winding machine can be hoisted and placed on the device, and the movable bearings can be replaced one by one online. Moreover, replacing one movable bearing only takes about 40 minutes, and replacing all four bearings takes about 2.5 hours. This not only reduces the workload and maintenance time of replacing movable bearings, but also allows for the replacement of only the problematic movable bearing when a problem occurs.
