[0004] The above patent has the following problems during actual use: the placement plate needs to be adjusted according to the maintenance height, and the guardrail needs to be adjusted according to the protection height, but the adjustment of the placement plate and the guardrail is controlled separately, the operation is cumbersome, and the work efficiency is low. Summary of the invention

[0005] The present invention is intended to provide a communication overhead maintenance device that is easy to disassemble, so as to solve the problem that the adjustment mode of the existing overhead maintenance equipment is complicated to operate.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an overhead communication maintenance device that is easy to disassemble, comprising a base, a telescopic rod is provided on the base, an operating box with a top opening is provided on the telescopic rod, a vertical groove is provided on the operating box, a vertical block is slidably connected in the vertical groove, the bottom of the vertical block is fixedly connected to the base, and a lifting plate is fixedly connected to the top of the vertical block, and the lifting plate can move vertically in the operating box; a plurality of mounting bolts are threadedly connected on the base; and a driving mechanism for driving the operating box to move vertically is also included.

[0007] The principles and advantages of this solution are:

[0008] 1. This solution connects the base to the maintenance site by installing bolts to fix the base so that the staff can perform stable maintenance.

[0009] 2. This solution drives the operation box to move upward through a driving mechanism to meet the maintenance height requirement; during the upward movement of the operation box, the lifting block moves downward relative to the operation box in the operation box, so that the lifting plate is close to the bottom of the operation box, and then the lifting plate sinks in the operation box, so that the lifting plate is located at a low position in the operation box, and the side walls of the operation box are used to protect the staff; compared with the existing technology, this solution can adjust the maintenance height and protect the staff at the same time, is easy to operate, and improves work efficiency.

[0010] 3. In this solution, when the operating box moves upward, the telescopic rod can be extended and retracted as needed, thereby guiding the vertical movement of the operating box and improving the stability of the movement.

[0011] Furthermore, an inclined groove is provided on the inner wall of the operating box, a slider is slidably connected in the inclined groove, and a movable block is provided on the slider; a transverse hole is provided on the lifting block, the movable block is transversely slidably connected to the transverse hole, an inclined block is provided on the top of the movable block, and the bottom of the movable block is against the bottom of the operating box.

[0012] Through the above arrangement, when the lifting plate is close to the bottom of the operating box, the operating box squeezes the movable block to move obliquely upward along the path of the inclined groove through the slider, so that the movable block moves to the left in the transverse hole, so that the movable block is close to the left side wall of the operating box, thereby reducing the space available for the staff to move and preventing the staff from tipping over or falling in the operating box.

[0013] During the movement of the movable block, the movable block drives the tilting block to move synchronously, so that the movable block and the tilting block form a V shape, providing a temporary resting place for the staff.

[0014] Furthermore, an elastic block is provided at the bottom of the operating box, and one end of the elastic block away from the bottom of the operating box is against the movable block; the elastic block is arc-shaped, and the convex part of the elastic block is set toward the lifting block, and the convex part of the elastic block is located on the movement trajectory of the lifting plate.

[0015] Through the above arrangement, when the movable block moves to the left in the transverse hole, the movable block approaches the vertical block, so that the movable block squeezes the right end of the elastic block to approach the left end of the elastic block, that is, the two ends of the elastic block approach each other, so that the upward protrusion of the elastic block becomes larger and larger; and, when the movable block moves to the left in the transverse hole, the lifting plate also approaches the bottom of the operating box, so that the protruding part of the elastic block is against the bottom of the lifting plate, thereby achieving support and limitation of the lifting plate, and preventing the lifting plate from continuing to approach the bottom of the operating box, thereby promoting the stability of the structure so that the staff can carry out maintenance smoothly.

[0016] Furthermore, both ends of the elastic block are provided with side grooves; a rotating shaft passing through the side grooves is rotatably connected to the operating box, and the rotating shaft can move laterally, vertically and rotate in the side grooves; an auxiliary groove is provided on the movable block, and the rotating shaft can move laterally, vertically and rotate in the auxiliary groove; a cam for abutting against the raised part of the elastic block is coaxially connected to the rotating shaft; and a power mechanism for driving the rotating shaft to rotate is also included.

[0017] Through the above arrangement, the power mechanism drives the rotating shaft to rotate, and the rotating shaft drives the cam to rotate, so that the raised portion of the cam abuts against the raised portion of the elastic block, thereby solidifying the elastic block and strengthening the support and limit of the lifting plate.

[0018] Furthermore, the power mechanism includes a wall groove opened on the inner wall of the operating box, a rack fixed to the bottom of the lifting plate, and a gear coaxially connected to the rotating shaft. The lifting block and the rack can move vertically in the wall groove, the gear is located on the movement trajectory of the rack, and the gear can engage with the rack.

[0019] Through the above arrangement, when the lifting plate approaches the bottom of the operating box, the rack also approaches the bottom of the operating box, so that the rack meshes with the gear to drive the gear to rotate, the gear drives the shaft to rotate, and the shaft drives the cam to rotate.

[0020] Furthermore, one end of the elastic block away from the movable block is against the vertical block; the bottom of the operating box is located on both sides of the cam and is rotatably connected to a circular shaft, and an elliptical block is coaxially connected to the circular shaft for abutting against the end of the cam and the end of the elastic block; it also includes a linkage mechanism that drives the two circular shafts to rotate as the rotating shaft rotates.

[0021] Through the above arrangement, during the rotation of the rotating shaft, the two circular shafts are driven to rotate through the linkage mechanism; the circular shaft drives the elliptical block to rotate, so that the two long axis ends of the elliptical block are respectively against the ends of the cam and the elastic block, that is, the two long axis ends of the left elliptical block are respectively against the left end of the cam and the left end of the elastic block, and the two long axis ends of the right elliptical block are respectively against the right end of the cam and the right end of the elastic block. On the one hand, the cam can be clamped and positioned to ensure the stability of the convex part of the cam against the convex part of the elastic block, that is, to ensure the solid stability of the cam to the convex part of the elastic block, and on the other hand, the two ends of the elastic block can be solidified to strengthen the support and limitation of the lifting plate.

[0022] Furthermore, the linkage mechanism includes a driving bevel gear coaxially connected to the rotating shaft and a driven bevel gear coaxially connected to the circular shaft, and the driving bevel gear is meshed with the driven bevel gear.

[0023] Through the above arrangement, during the rotation of the shaft, the shaft drives the active bevel gear to rotate, the active bevel gear meshes with the driven bevel gear to drive the driven bevel gear to rotate, and the driven bevel gear drives the circular shaft to rotate.

[0024] Furthermore, a first wedge block is provided on the rack, and the first wedge block can move vertically in the wall groove, and a limit groove is provided on the side wall of the first wedge block; a side groove is provided on the side wall of the operating box, and the side groove is communicated with the wall groove, and a second wedge block for being squeezed by the first wedge block is slidably connected in the side groove, and a spring is provided between the second wedge block and the operating box, and the second wedge block slidably cooperates with the limit groove.

[0025] Through the above arrangement, when the rack approaches the bottom of the operating box, the first wedge block squeezes the second wedge block to move to the right, and the spring is stretched; the rack continues to approach the bottom of the operating box, so that the second wedge block abuts against the side wall of the first wedge block; the rack continues to approach the bottom of the operating box, so that the second wedge block is horizontally opposite to the limiting groove, and the second wedge block slides into the limiting groove under the action of the spring, thereby stopping the first wedge block and then stopping the rack. The gear, the rotating shaft and the circular shaft are stopped, that is, the cam and the elliptical block are stopped, and the stability of the elastic block is further improved.

[0038] The specific implementation process is as follows:

[0039] When in use, the base 10 is fixed by connecting it with the maintenance place through the mounting bolts 15. The staff enters the operation box 12 and stands on the lifting plate 14, which is located at a high position in the operation box 12 so that the staff can enter the operation box 12.

[0040] Start the cylinder 16, and the output shaft of the cylinder 16 drives the operation box 12 to move upward to the specified position, and close the cylinder 16 to achieve the positioning of the operation box 12; during the upward movement of the operation box 12, the lifting block moves downward relative to the operation box 12 in the operation box 12, so that the lifting plate 14 is close to the bottom of the operation box 12, and then the lifting plate 14 sinks in the operation box 12, so that the lifting plate 14 is located at a low position in the operation box 12, and the side wall of the operation box 12 is used to protect the staff.

[0041] While the lifting plate 14 is approaching the bottom of the operation box 12, the operation box 12 squeezes the movable block 21 to move obliquely upward along the path of the inclined groove 20 through the slider, so that the movable block 21 moves to the left in the transverse hole 22, so that the movable block 21 is close to the left side wall of the operation box 12, thereby reducing the space available for the staff to move and preventing the staff from tipping over or falling in the operation box 12; during the movement of the movable block 21, the movable block 21 drives the inclined block 23 to move synchronously, so that the movable block 21 and the inclined block 23 form a V shape, providing a temporary resting place for the staff.

[0042] During the period when the movable block 21 moves to the left in the transverse hole 22, the movable block 21 approaches the vertical block 13, so that the movable block 21 squeezes the right end of the elastic block 30 to approach the left end of the elastic block 30, that is, the two ends of the elastic block 30 are close, so that the elastic block 30 bulges upward more and more; and, during the period when the movable block 21 moves to the left in the transverse hole 22, the lifting plate 14 is also close to the bottom of the operating box 12, so that the raised part of the elastic block 30 is against the bottom of the lifting plate 14, thereby achieving support and limitation of the lifting plate 14, and also preventing the lifting plate 14 from continuing to approach the bottom of the operating box 12, thereby promoting the stability of the structure so that the staff can smoothly perform maintenance.

[0043] When the lifting plate 14 approaches the bottom of the operating box 12, the rack 35 also approaches the bottom of the operating box 12, so that the rack 35 meshes with the gear 36 to drive the gear 36 to rotate, the gear 36 drives the shaft 32 to rotate, and the shaft 32 drives the cam 33 to rotate, so that the raised portion of the cam 33 is abutted against the raised portion of the elastic block 30, so that the elastic block 30 can be solidified, and the support and limit of the lifting plate 14 can be strengthened.

[0045] When the rack 35 approaches the bottom of the operating box 12, the first wedge block 50 squeezes the second wedge block 52 to move to the right, and the spring 53 is stretched; the rack 35 continues to approach the bottom of the operating box 12, so that the second wedge block 52 abuts against the side wall of the first wedge block 50; the rack 35 continues to approach the bottom of the operating box 12, so that the second wedge block 52 is horizontally opposite to the limiting groove 51, and the second wedge block 52 slides into the limiting groove 51 under the action of the spring 53, thereby stopping the first wedge block 50, and then stopping the rack 35, and stopping the gear 36, the rotating shaft 32, and the circular shaft 40, that is, stopping the cam 33 and the elliptical block 41, further improving the stability of the elastic block 30.
