The frame is provided with an arc long hole 19, an elliptical long hole 20, a locating pin long hole 21, a floating block mounting shaft 18, a second rope guiding wheel mounting shaft 22, a third tensioning wheel mounting shaft 23, a lifting hook mounting shaft 24, a crawling wheel mounting shaft 25 and a supporting plate mounting hole 26. The sheave 11 is rotatably mounted to the frame by a sheave mounting shaft 25.
The lower end of the floating block 9 is wider, and the left half part of the lower end of the floating block 9 is rotatably arranged on a floating block mounting shaft 18; the right half of the lower end of the slider 9 is provided with a mounting shaft of the first tension pulley 10, and the mounting shaft of the first tension pulley 10 is mounted in the circular arc long hole 19. The circle center of the circle where the arc of the arc long hole 19 is located is: the axle center of the slider mounting axle 18 on the intersecting plane of the slider mounting axle 18 and the circular arc long hole 19 ensures that the slider 9 and the mounting axle of the first tensioning wheel 10 rotate within a certain angle range along the circular arc long hole 19. The upper end of the floating block 9 is provided with a first rope guiding wheel installation shaft, and the first rope guiding wheel 8 is rotatably arranged on the first rope guiding wheel installation shaft.
The second tensioning wheel mounting shaft 27 is arranged in the oval long hole 20, and the long axis of the oval long hole 20 is perpendicular to the central axis of the climbing rope wheel 11; the mounting shaft of the second tensioning wheel 5 is movable along the long axis of the oblong hole 20.
The positioning pin long hole 21 is parallel to the central shaft of the climbing rope pulley 11; the positioning pin 28 is mounted on the positioning pin long hole 21. The frame is also provided with a floating support 3, the floating support 3 is U-shaped, the opening end of the floating support 3 is connected with a second tensioning wheel mounting shaft 27, and the floating support 3 does not influence the rotation of the second tensioning wheel 5. The two ends of the floating bracket 3 are provided with positioning pin holes 29, and the positioning pins 28 are positioned between the positioning pin holes 29 on the two sides; due to the arrangement of the positioning pin holes 29, the positioning pins 28 do not influence the floating bracket 3 to drive the second tensioning wheel 5 to move.

When the rope climbing device works, ropes 7 pass through the first rope guiding wheels 8 and then pass through grooves between the sheet base belt 2 and the crawling wheels 11, and the left rear part freely sags to the ground through the second rope guiding wheels 12. The upper end of the rope 7 is fixed to the destination height.
The rope 7 generates friction force through the extrusion of the crawling wheel 11 and the piece base belt 2, and the rope climbing device moves along the rope 7 under the rotation action of the crawling wheel 11.
When the rope climbing device is loaded, the first rope guiding wheel 8, the floating block 9 and the first tensioning wheel 10 can tension the piece base belt 2, so that the pressure of the piece base belt 2 to the rope 7 is increased, and meanwhile, the pressure between the rope 7 and the crawling wheel 11 is increased, and the friction force between the rope 7 and the crawling wheel 11 and between the rope 7 and the piece base belt 2 can be increased.
The floating bracket 3, the adjusting bolt 4, the second tensioning wheel 5 and the spring together form a tensioning adjusting device. The tensioning adjusting device compresses the spring through the adjusting bolt 4, the spring is compressed, and then the floating support 3 is outwards elastic, so that the floating support 3 drives the second tensioning wheel 5 to move along the long axis of the oval long hole 20, the distance between the second tensioning wheel 5 and the third tensioning wheel 13 and the first tensioning wheel 10 is adjusted, and the tension of the sheet base band is adjusted. Before the crawler operates, the tension of the sheet base belt is adjusted according to the weight of the load, if the overload load is carried out, the friction force between the sheet base belt 2 and the rope 7 is too small, the slipping phenomenon occurs, and the crawler cannot operate, so that the crawler cannot work under the overload condition, and the safe operation is ensured.
When the load increases, the tension of the sheet base belt 2 is increased by the first rope guide wheel 8, the floating block 9 and the first tensioning wheel 10, and meanwhile, the pressure between the rope 7 and the crawling wheel 11 is increased, so that the friction force between the rope 7 and the crawling wheel 11 and between the rope 7 and the sheet base belt 2 can be increased, the safe operation of the rope climbing device can be ensured, and the friction force between the rope 7 and the crawling wheel 11 and between the rope 7 and the sheet base belt 2 can be automatically adjusted according to different loads.
One of the innovative points of the present invention is the use of the sheet base belt 2 to increase the friction between the ropes 7 and the crawling wheel 11 and between the ropes 7 and the sheet base belt 2. The sheet base band 2 has good flexibility, can change along with the change of the rope 7, has good parcel nature simultaneously, can wrap up rope 7 in the slot between crawling wheel 11 and the sheet base band 2 in real time in the rope climbing ware working process.
The rope climbing device can automatically adjust the friction force between the rope 7 and the crawling wheel 11 and between the rope 7 and the piece of base belt 2 according to load change, thereby achieving the purpose of energy saving. In addition, the tensioning adjusting device can limit the maximum load of the rope climbing device, prevent overload operation and effectively ensure safe operation of the rope climbing device.
