Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-7, the push-pull part is composed of two braking devices 7 and a first hydraulic cylinder 2, two ends of the first hydraulic cylinder 2 are respectively hinged with one braking device 7, the inner side of a braking frame 8 of the braking device 7 is correspondingly provided with a pulley 4 and is installed on a track 1, one end of a braking block 8 is respectively inserted into through holes at two sides of the braking frame 8, the other end is hinged with the upper end of a connecting plate 10, the middle part of the connecting plate 10 is hinged with the braking frame 8 through a small connecting plate 11, and the lower ends of the connecting plates 10 at two sides of the braking device 7 are connected through a second hydraulic cylinder 3; the hanging rack 12 is symmetrically provided with pulleys 4 and is arranged on the track 1, the two ends of the hanging rack 12 are welded with baffle plates 13, the partition plates 14 of the hanging rack 12 are connected through the stud bolts 5, and the adjacent hanging racks 12 are connected through the protective chains 15. The first hydraulic cylinder 2 and the second hydraulic cylinder 3 are connected with a hydraulic system 6, and the push-pull parts are respectively provided with a group at two ends of the hanging frame 12 and are connected with the hanging frame 12 through a connecting rod 16. The hanging frame 12 is provided with more than two groups.
In the coal mine production process, the cable 17 needs to be pushed together with the continuous pushing of the working face, at the moment, the hydraulic system 6 of the push-pull part at the outer side of the roadway is controlled to extend the second hydraulic cylinder 3 of the rear end braking device 7, the second hydraulic cylinder 3 of the front end braking device 7 contracts, at the moment, the brake block 9 of the rear end braking device 7 is abutted against the rail 1 to enable the rail to be in a locking state, the front end brake block 9 is not in contact with the rail 1, and the front end braking device 7 can move; then the hydraulic system 6 is controlled to extend the first hydraulic cylinder 2, so that the front end braking device 7 moves forwards, and the baffle 13 of the hanging frame 12 is pushed to drive the pulley 4 to move forwards; when the first hydraulic cylinder 2 reaches the maximum stroke, the hydraulic system 6 is controlled to extend the second hydraulic cylinder 3 of the front end braking device 7, at the moment, the brake block 9 contacts the track 1 to enable the track to be in a locking state, and then the hydraulic system 6 is controlled to close the rear end braking device 7 to enable the rear end braking device 7 to move; then the hydraulic system 6 is controlled to contract the first hydraulic cylinder 2; when the first hydraulic cylinder 2 reaches the minimum stroke, the hydraulic system 6 is controlled to open the rear end braking device 7 to enable the rear end braking device to be in a locking state, and at the moment, the monorail crane completes one-time movement.
