[0037] The bottom of the support frame is supported on the ground, and the top of the support frame forms a supporting portion for the inclined installation of the arc-shaped drag plate 7. The arc-shaped drag plate 7 is fixedly installed on the inner side of the supporting portion of the support frame. The arc-shaped drag plate 7 is in an inclined state, and has an inclined arc-shaped opening on the top. A bayonet 11 is provided on the surface of the arc-shaped drag plate 7. The thrust piece 12 can be detachably fixed at the bayonet 11 position of the arc-shaped drag plate 7, and is used to support the inclined shaft TBM dismantling parts placed on the inner side of the arc-shaped drag plate 7.

[0038] When in use, first remove the thrust piece 12, use the lifting equipment to place the inclined shaft TBM dismantling parts (cylindrical shape) on the inner side of the arc-shaped drag plate 7, and then install the thrust piece 12. After loosening the lifting rope, the inclined shaft TBM dismantling parts are stably placed on the arc-shaped guide platform device for inclined shaft TBM dismantling to facilitate subsequent lifting.

[0039] When in use, the TBM dismantling parts hoisted out of the inclined shaft are in an inclined state, which is not convenient to place directly on a flat surface. They can be placed on the arc guide platform device for inclined shaft TBM dismantling, thereby reducing the difficulty of hoisting and improving work efficiency.

[0040] When the TBM dismantling parts are stepped and lifted obliquely toward the steep inclined shaft of the dismantling cavern, the arc-shaped guide platform device for the inclined shaft TBM dismantling machine is used to guide the TBM dismantling parts (cylindrical shape) (when using this method, the thrust piece 12 needs to be removed), which is conducive to pushing the TBM dismantling parts obliquely upward.

The top of the primary rear support 10 is fixedly connected with a rear cross beam 8, and the top of the rear cross beam 8 is fixedly connected with a plurality of secondary rear support members 9, and the heights of the plurality of secondary rear support members 9 are different, so that the top line of the plurality of secondary rear support members 9 is fitted into an arc shape, which also corresponds to the bottom of the arc-shaped carriage 7. The side panel support member 1 is fixedly mounted on the rear cross beam 8. The end portion of the side panel support 1 is fixedly connected to the arc-shaped drag plate 7, and the two ends of the connecting short frame 5 are respectively fixedly connected to the front cross beam 3 and the rear cross beam 8 to increase the stability between the front cross beam 3 and the rear cross beam 8.
