In addition, the driving assembly 203 serves as a driving member of the step assembly 204, which can enable the step assembly 204 to unfold and assist the staff to complete the work.

[0044] Furthermore, the frame assembly 201 includes an installation frame 201a arranged on the inner side of the upper lifting ear 102, a reinforcing rod 201b for reinforcing the installation frame 201a, and a fixed frame 201c arranged at the bottom of the installation frame 201a, wherein the diameter of the installation frame 201a is the same as the gap between the bearing blocks 103, and can be well inserted and is not prone to shaking. In addition, by adding the reinforcing rod 201b, the rigidity of the installation frame 201a is increased to prevent the installation frame 201a from being deformed. Finally, the fixed frame 201c is fixed to the bottom of the reinforcing rod 201b.

[0045] Specifically, the rotating assembly 202 includes a fixed plate 202a arranged inside the fixed frame 201c, a bottom plate 202b arranged at the bottom of the fixed plate 202a, a connecting shaft 202c arranged at the top of the bottom plate 202b corresponding to the two sides of the fixed plate 202a, and a supporting spring 202d arranged between the fixed plate 202a and the bottom plate 202b, wherein the fixed plate 202a is fixed inside the fixed frame 201c, and the bottom plate 202b is arranged at the bottom of the fixed plate 202a, and the two are connected by the connecting shaft 202c, and the bottom plate 202b can rotate freely. In addition, the bottom plate 202b is designed in a T-shape, and the end face of the fixed plate 202a is arranged in an arc shape, so that the bottom plate 202b can rotate freely. In addition, by arranging a supporting spring 202d between the connecting shaft 202c and the bottom plate 202b, a large rotation range between the two is prevented to prevent shaking.

[0046] Furthermore, the driving assembly 203 includes an articulated block 203a disposed on one side of the interior of the fixed frame 201c, a hydraulic cylinder 203b disposed inside the articulated block 203a, a connecting cross bar 203e disposed at the driving end of the hydraulic cylinder 203b, a connecting rod 203d sleeved on the outside of the connecting cross bar 203e, a connecting rod 203d disposed at the other end of the connecting rod 203d, and a fixed rod 203f disposed at the other end of the connecting rod 203d, wherein the articulated block 203a is fixed to one side of the interior of the fixed frame 201c, and the hydraulic cylinder 203b is disposed inside the articulated block 203a, and the hydraulic cylinder 203e is disposed at the driving end of the hydraulic cylinder 203b. The hydraulic cylinder 203b is arranged at the other end of the hinge block 203a, and the two are hinged so that the hydraulic cylinder 203b can rotate freely. In addition, a connecting vertical rod 203c is connected to the driving end of the hinge block 203a, and a connecting cross rod 203e is connected to the center of the connecting vertical rod 203c. When the hydraulic cylinder 203b is driven, one end of the connecting vertical rod 203c will move, and a connecting rod 203d is connected to the other end of the connecting vertical rod 203c. Therefore, after the connecting rod 203d moves, it will drive the connecting rod 203d to move.

Since the other end of the connecting vertical rod 203c is connected to the connecting rod 203d, the connecting rod 203d is driven to move under the action of the connecting vertical rod 203c. In the process of moving the connecting rod 203d, the first rotating rod 204b will be driven to move, and the standing board 204d will push the second rotating rod 204c to move. The first rotating rod 204b, the second rotating rod 204c and the standing board 204d cooperate with each other, so that multiple standing boards 204d can be fully unfolded to facilitate workers to operate and construct.

[0052] Furthermore, the accommodating assembly 302 includes an accommodating hole 302a opened inside the connecting sleeve 301c, a through hole 302b penetrating inside the accommodating hole 302a, and the through hole 302b penetrates the side wall of the connecting sleeve 301c;

[0053] The fixing assembly 303 includes a connecting wedge 303a disposed inside the through hole 302b, a moving rod 303b disposed at the opposite end of the connecting wedge 303a, and the other end of the moving rod 303b extends to the outside of the connecting sleeve 301c, a return spring 303c sleeved on the outer wall of the moving rod 303b, and a baffle 303d disposed at the end of the moving rod 303b, wherein the receiving hole 302a is opened at the bottom end of the connecting sleeve 301c, and the receiving hole 302a is penetrated by the through hole 302b. In addition, the other end of the threaded sleeve 301b passes through the connecting sleeve 301c, and a connecting wedge block 303a is arranged inside the accommodating hole 302a, and a moving rod 303b is fixed to the outward end of the connecting wedge block 303a, and a return spring 303c is sleeved on the outer wall of the moving rod 303b, which helps the connecting wedge block 303a to return to its original position. In addition, a moving rod 303b is fixed to the outward end of the moving rod 303b to prevent the moving rod 303b from sinking into the interior of the connecting sleeve 301c.

[0054] Furthermore, the receiving assembly 304 includes a base 304a disposed on the top of the standing plate 204d, a guide rod 304b disposed on the top of the base 304a, a moving block 304c sleeved on the outer wall of the guide rod 304b, and an end 304d disposed on the top of the guide rod 304b, and a receiving groove 304e opened inside the end 304d, wherein the base 304a is disposed directly below the connecting sleeve 301c, and the base 304a is fixedly connected to the standing plate 204d. A guide rod 304b is fixed at the top of the base 304a, and a moving block 304c is slidably connected to the outside of the guide rod 304b, an end head 304d is fixed at the top of the guide rod 304b, and a receiving groove 304e capable of receiving the guide rod 304b is provided at the bottom of the end head 304d, wherein the diameter of the end head 304d is the same as the diameter of the receiving hole 302a, and the diameter of the moving block 304c is slightly smaller than the diameter of the end head 304d and is the same as the diameter of the receiving groove 304e.

[0055] The operation process of this embodiment is as follows: when the standing plate 204d is fully unfolded, the connecting sleeve 301c is moved down by rotating the threaded sleeve 301b and is sleeved on the outside of the base 304a. During the descending process of the connecting sleeve 301c, the connecting wedge block 303a will expand outward due to the pressure of the end head 304d, and at the same time, the return spring 303c is deformed to generate elastic force. When the connecting wedge block 303a moves below the end head 304d, the connecting wedge block 303a will no longer be hindered. Therefore, under the action of the return spring 303c, the connecting wedge block 303a will return to its original position and be at the lower end surface of the end head 304d. At this time, the reinforcement of the standing plate 204d is completed, and then continue When the connecting sleeve 301c moves downward, the connecting wedge block 303a will first expand to both sides under the force of the moving block 304c. When the connecting wedge block 303a moves to the lower half of the moving block 304c, the connecting sleeve 301c is controlled to move upward, and the moving block 304c will be driven to move upward, and then the moving block 304c will enter the interior of the accommodating groove 304e. The connecting sleeve 301c continues to move upward, and under the action of the moving block 304c, the connecting wedge block 303a will move to the outside. Continuing to move upward, the connecting wedge block 303a will detach from the moving block 304c and contact the end 304d, thereby contacting the fixation of the standing plate 204d, completing the disassembly of the device, so that the device can be used repeatedly.

[0059] S3. The connecting rod assembly 301 is then set at the top of the lifting lug 102, and then the distance between the connecting sleeve 301c and the standing plate 204d is adjusted by rotating the threaded sleeve 301b;

[0060] S4. When the adjustment distance is appropriate, the connecting wedge 303a will be stuck at the bottom of the end 304d, completing the fixation of the standing board 204d, making the standing board 204d more stable to ensure the safety of the staff.

[0061] The operation process of this embodiment is: first, use the installation frame 201a to set up the operating platform component 200 as a whole on the diagonal support body 101, and then start the hydraulic cylinder 203b to unfold the standing board 204d for the staff to stand and facilitate operation, and then rotate the threaded sleeve 301b to move the connecting sleeve 301c downward, so that the connecting wedge block 303a is stuck at the lower end surface of the end head 304d, thereby completing the reinforcement of the standing board 204d to prevent shaking. In addition, by controlling the connecting sleeve 301c to move downward first and then upward, the connecting wedge block 303a is no longer stuck at the lower end surface of the end head 304d, and the device is disassembled for reuse.
