[0014] A method for using a cantilevered high-altitude breaking device includes the following steps: Step 1: First, the hydraulic lifting system drives the work box to move upward along the vertical beam. The work box moves on the vertical beam using rollers and positioning wheels, so that the work box moves to the position below the cantilever structure. The infrared sensor detects the distance between the work box and the lower surface of the cantilever structure. When the infrared sensor detects the distance to the set value, the movement of the work box is stopped, and the drilling rig is set below the cantilever structure. Step Two: Then, by moving the work box vertically, the movable frame is unfolded, causing multiple fixed frames and collection bags to unfold vertically, forming a material discharge channel. As the fixed frame unfolds, the mounting frame and the third connecting rod move vertically. The two third connecting rods extend vertically, and the lower third connecting rod drives the second connecting rod to move upward together. The extrusion block moves together with the second connecting rod, so that the inclined surface of the extrusion block presses against the inclined surface of the inner wall of the extrusion groove on the first connecting rod, pushing the first connecting rod to one side. The fixed column at one end of the first connecting rod moves horizontally, and the fixed column presses against the movable block, pulling the movable block to rotate downward around the second mounting axis. The connecting column at one end of the movable block presses against the first movable groove, causing the movable plate to rotate downward, so that multiple movable plates are tilted downward. Step 3: Next, the first connecting rod drives the limiting column to move horizontally to one side. The limiting column presses against one end of the limiting block, causing the limiting block to rotate clockwise around the third mounting shaft. The limiting column passes between the two limiting blocks and, using the elasticity of the torsion spring, drives the limiting block to rotate counterclockwise. The protrusions at the other ends of the two limiting blocks fit with the limiting column, limiting and fixing the limiting column and the first connecting rod, so that the movable plate is tilted. At this time, the ultrasonic probe on the drilling rig is used to detect the steel bars in the cantilever structure and avoid the steel bar position. Through the operation of the hydraulic cylinder, the second rocker arm and the first rocker arm are driven to rotate, so that the drilling rig moves towards the cantilever structure. The operation of the drilling rig is used to crush the concrete of the cantilever structure. The crushed waste falls into the work box, enters the feed hopper from the collection trough, and falls down along multiple fixed frames and collection bags. The movable plate is used to buffer the waste. Step four; Finally, when the crushed waste falls onto the uppermost movable plate, the pressure sensor on the movable plate detects the impact force and obtains the detection value. By calculating the detection value, the height of the waste falling is obtained. When the detection value is greater than the set threshold, it indicates that the waste has fallen too high, and the signal is fed back to the crushing device. At this time, the operating box rises, and the height of the operating box is adjusted. The weight of the falling waste is determined by the detection value obtained by the pressure sensor. When the detection value is greater than the set weight value, it reflects that the weight and volume of the crushed waste are large, and feedback is sent to the crushing device. By adjusting the running speed of the drilling rig, the working intensity of the cantilever structure is changed, and the degree of crushing of the waste is adjusted.

[0015] The technical effects and advantages of this invention are as follows: This invention unfolds multiple fixed frames, causing the mounting frame and the third connecting rod to move vertically, pulling the second connecting rod upward. The inclined surface of the extrusion block presses against the inclined surface of the inner wall of the extrusion groove on the first connecting rod, pushing the first connecting rod to one side. The fixed column at one end of the first connecting rod moves horizontally, pressing against the movable block and pulling the movable block to rotate downward around the second mounting axis. The connecting column at one end of the movable block presses against the first movable groove, causing the movable plate to rotate downward. This causes multiple movable plates to be tilted downward, blocking the falling waste, reducing the speed of the falling waste, reducing the damage caused by the potential energy of the waste, improving the safety of the operation, and facilitating the cleaning of the waste. When the first connecting rod moves the limiting post to one side, the limiting post presses against one end of the two limiting blocks, pushing the two limiting blocks to rotate clockwise. The limiting post passes between the two limiting blocks. When the first connecting rod moves the limiting post to the other side, the limiting post presses against the protrusion, pushing the limiting block to rotate counterclockwise. The outer walls of the two limiting blocks press against each other, preventing the two limiting blocks from rotating. This limits the limiting post and ensures the stability of the first connecting rod, the movable block, and the movable plate. This invention uses the operation of hydraulic cylinders to drive the second and first rocker arms to rotate, causing the drilling rig to move towards the cantilever structure. The drilling rig breaks up the concrete of the cantilever structure, and the broken waste falls into the working box, enters the feed hopper from the collection trough, and falls down along multiple fixed frames and collection bags. The movable plate buffers the waste to prevent it from splashing and improves the safety of the operation. Attached Figure Description

The fixed column 416 moves horizontally, causing it to push one end of the movable block 49, thus rotating the movable block 49. Pressure sensors 418 are fixedly installed on the movable plate 47. These sensors are arranged at equal intervals. The pressure sensors 418 detect the impact force received by the movable plate 47.

The protrusion 55 is set in an arc shape and is in contact with the outer wall of the limiting post 54. The protrusion 55 is used to block the limiting post 54. When the first connecting rod 417 moves the limiting post 54 to one side, the limiting post 54 presses against one end of the two limiting blocks 51, pushing the two limiting blocks 51 to rotate clockwise. The limiting post 54 passes between the two limiting blocks 51. When the first connecting rod 417 moves the limiting post 54 to the other side, the limiting post 54 presses against the protrusion 55, pushing the limiting blocks 51 to rotate counterclockwise. The outer walls of the two limiting blocks 51 press against each other, preventing the two limiting blocks 51 from rotating, thus limiting the limiting post 54 and ensuring the stability of the first connecting rod 417, the movable block 49, and the movable plate 47. The extrusion groove 56 is formed in the first connecting rod 417. At the other end of 17, the inner wall of the extrusion groove 56 is inclined. The extrusion groove 56 is used to install the second connecting rod 57 and the extrusion block 58. The second connecting rod 57 is slidably inserted into the extrusion groove 56. The second connecting rod 57 is T-shaped. The second connecting rod 57 moves in the vertical direction to drive the extrusion block 58 to move together. The extrusion block 58 is fixedly connected to the bottom of the second connecting rod 57. One end of the extrusion block 58 is inclined. The inclined surface of the extrusion block 58 is in contact with the inclined surface of the extrusion groove 56. When the second connecting rod 57 drives the extrusion block 58 to move upward, the inclined surface of the extrusion block 58 presses against the inclined surface of the inner wall of the extrusion groove 56, pushing the first connecting rod 417 to one side.The pushing block 59 is fixedly connected to the bottom of the second connecting rod 57. One end of the pushing block 59 is in contact with the outer wall of the other end of the limiting block 51. The pushing block 59 moves vertically with the second connecting rod 57. The mounting frame 510 has a sliding groove. The pushing block 59 moves in the sliding groove. When the second connecting rod 57 drives the pushing block 59 to move vertically downward, one end of the pushing block 59 presses against one end of the lower limiting block 51, pushing the limiting block 51 to rotate, releasing the limitation on the limiting post 54, so that the movable plate 47 can rotate to a horizontal position. The mounting frame 510 is fixedly connected to one side of the outer wall of the fixed frame 43. The mounting frame 510 is arranged vertically and alternately. The mounting frame 510 is used to install the third connecting rod 511. The mounting frame 510 moves together with the fixed frame 43. The third connecting rod 511 is slidably inserted. The third connecting rod 511, positioned on the mounting bracket 510, is T-shaped. One of the third connecting rods 511 has a connecting groove that slides through the second connecting rod 57. Two adjacent fixing brackets 43 are connected to the third connecting rod 511 via the mounting bracket 510. When the fixing bracket 43 is vertically unfolded and retracted, it moves the mounting bracket 510 vertically. When multiple fixing brackets 43 are unfolded, the third connecting rod 511 slides out of the mounting bracket 510, pulling the second connecting rod 57 vertically downwards. One end of the connecting seat 512 is fixedly connected to the bottom end of one of the third connecting rods 511, and the other end of the connecting seat 512 is fixedly connected to the top end of another third connecting rod 511, thus connecting the two third connecting rods 511.

[0036] A method for using a cantilevered high-altitude breaking device includes the following steps: Step 1: First, the hydraulic lifting system drives the work box 21 to move upward along the vertical beam 1. The work box 21 moves on the vertical beam 1 using rollers 37 and positioning wheels 36, so that the work box 21 moves to the position below the cantilever structure. The infrared sensor 27 detects the distance between the work box 21 and the lower surface of the cantilever structure. When the infrared sensor 27 detects the distance to the set value, the movement of the work box 21 is stopped, and the drilling rig 25 is set below the cantilever structure. Step 2: Then, by moving the work box 21 vertically, the movable frame 45 is unfolded, so that multiple fixed frames 43 and collection bags 44 are unfolded vertically to form a material discharge channel. As the fixed frame 43 unfolds, the mounting frame 510 and the third connecting rod 511 are moved vertically. The two third connecting rods 511 extend vertically, and the lower third connecting rod 511 drives the second connecting rod 57 to move upward together. The extrusion block 58 moves together with the second connecting rod 57, so that the inclined surface of the extrusion block 58 presses against the inclined surface of the inner wall of the extrusion groove 56 on the first connecting rod 417, pushing the first connecting rod 417 to one side. The fixed column 416 at one end of the first connecting rod 417 moves horizontally, and the fixed column 416 presses against the movable block 49, pulling the movable block 49 to rotate downward around the second mounting shaft 410. The connecting column 413 at one end of the movable block 49 presses against the first movable groove 412, driving the movable plate 47 to rotate downward, so that multiple movable plates 47 are tilted downward. Step 3: Next, the first connecting rod 417 drives the limiting post 54 to move horizontally to one side. The limiting post 54 presses against one end of the limiting block 51, causing the limiting block 51 to rotate clockwise around the third mounting shaft 52. The limiting post 54 passes between the two limiting blocks 51, and using the elastic action of the torsion spring 53, it drives the limiting block 51 to rotate counterclockwise. The protrusions 55 at the other end of the two limiting blocks 51 fit against the limiting post 54, limiting and fixing the limiting post 54 and the first connecting rod 417, so that the movable plate 47 is tilted. At this time, the ultrasonic probe 28 on the drilling rig 25 is used to detect the steel bars in the cantilever structure. Avoiding the steel bar position, the operation of the hydraulic cylinder 26 drives the second rocker arm 24 and the first rocker arm 23 to rotate, so that the drilling rig 25 moves towards the cantilever structure. The operation of the drilling rig 25 is used to crush the concrete of the cantilever structure. The crushed waste falls into the work box 21, enters the feed hopper 42 from the collection trough 41, and falls down along multiple fixed frames 43 and collection bags 44. The movable plate 47 is used to buffer the waste. Step four; Finally, when the crushed waste falls onto the uppermost movable plate 47, the pressure sensor 418 on the movable plate 47 detects the impact force and obtains the detection value. By calculating the detection value, the height of the waste falling is obtained. When the detection value is greater than the set threshold, it indicates that the waste has fallen too high, and the signal is fed back to the crushing device. At this time, the operating box 21 rises, and the height of the operating box 21 is adjusted. The weight of the falling waste is determined by the detection value obtained by the pressure sensor 418. When the detection value is greater than the set weight value, it reflects that the weight and volume of the crushed waste are large, and the feedback is fed back to the crushing device. By adjusting the running speed of the drilling rig 25, the working intensity of the cantilever structure is changed, and the degree of crushing of the waste is adjusted.

10. A method of using a cantilevered high-altitude crushing device, characterized in that, Using a cantilever structure high-altitude breaking device as described in any one of claims 1-9 includes the following steps: Step 1: First, the hydraulic lifting system drives the work box (21) to move upward along the vertical beam (1). The work box (21) moves on the vertical beam (1) using rollers (37) and positioning wheels (36) so that the work box (21) moves to the position below the cantilever structure. The infrared sensor (27) detects the distance between the work box (21) and the lower surface of the cantilever structure. When the infrared sensor (27) detects the distance to the set value, the movement of the work box (21) is stopped, and the drilling rig (25) is set below the cantilever structure. Step 2: Then, by moving the work box (21) vertically, the movable frame (45) is unfolded, causing multiple fixed frames (43) and the collection bag (44) to unfold vertically, forming a feeding channel. As the fixed frame (43) unfolds, the mounting frame (510) and the third connecting rod (511) move vertically. The two third connecting rods (511) extend vertically, and the lower third connecting rod (511) drives the second connecting rod (57) to move upward together. The extrusion block (58) moves together with the second connecting rod (57), causing the extrusion block (58) to move upward together. The inclined surface of the first connecting rod (417) presses against the inclined surface of the inner wall of the extrusion groove (56), pushing the first connecting rod (417) to move to one side. The fixed column (416) at one end of the first connecting rod (417) moves horizontally. The fixed column (416) presses against the movable block (49), pulling the movable block (49) to rotate downward around the second mounting shaft (410). The connecting column (413) at one end of the movable block (49) presses against the first movable groove (412), causing the movable plate (47) to rotate downward, so that multiple movable plates (47) are tilted downward. Step 3: Next, the first connecting rod (417) drives the limiting post (54) to move horizontally to one side. The limiting post (54) presses against one end of the limiting block (51), causing the limiting block (51) to rotate clockwise around the third mounting shaft (52). The limiting post (54) passes between the two limiting blocks (51), and with the elastic action of the torsion spring (53), it drives the limiting block (51) to rotate counterclockwise. The protrusions (55) at the other end of the two limiting blocks (51) fit against the limiting post (54), limiting and fixing the limiting post (54) and the first connecting rod (417), causing the movable plate (47) to tilt. In this setup, the ultrasonic probe (28) on the drilling rig (25) is used to detect the reinforcing bars in the cantilever structure. Avoiding the position of the reinforcing bars, the operation of the hydraulic cylinder (26) drives the second rocker arm (24) and the first rocker arm (23) to rotate, so that the drilling rig (25) moves towards the cantilever structure. The operation of the drilling rig (25) is used to crush the concrete of the cantilever structure. The crushed waste falls into the work box (21), enters the feed hopper (42) from the collection trough (41), falls down along multiple fixed frames (43) and collection bags (44), and is buffered by the movable plate (47). Step 4; Finally, when the crushed waste falls onto the uppermost movable plate (47), the impact force is detected by the pressure sensor (418) on the movable plate (47), and the detection value is obtained. The height of the waste falling is obtained by calculating the detection value. When the detection value is greater than the set threshold, it indicates that the waste falls to a large height. The signal is fed back to the crushing device. At this time, the operating box (21) rises and the height of the operating box (21) is adjusted. The weight of the falling waste is judged by the detection value obtained by the pressure sensor (418). When the detection value is greater than the set weight value, it reflects that the weight and volume of the crushed waste are large. The feedback is fed back to the crushing device. The operating speed of the drilling rig (25) is adjusted to change the working intensity of the cantilever structure and adjust the degree of crushing of the waste.
