Holes of the same size are formed at the positions corresponding to the installation holes 65 on the surface of the first connecting plate 61. The first connecting plate 61 and the connecting block 66 are fixed by bolts. During installation, first, the first connecting plate 61 is welded to the main beam of the crane, and at the same time, the second connecting plate 63 is welded to the platform 1. During assembly, only the platform 1 needs to be hoisted to the position of the first connecting plate 61, the connecting block 66 is attached to the first connecting plate 61, and it can be fixed by bolts. It has the effect of being convenient for disassembly and assembly, reduces the labor intensity of workers, improves the installation efficiency, reduces the risk of high-altitude installation, increases safety protection, and also reduces the overall volume of the hoist by means of disassembly and assembly, which can achieve the effect of being convenient for transportation and increases the aesthetic degree.

[0022] A workpiece placement groove 4 is formed at the rear edge of the upper surface of the platform 1. A permanent magnet plate is embedded in the workpiece placement groove 4. The thickness of the permanent magnet plate is 3 mm. The disassembled screws and nuts can be placed in the workpiece placement groove 4, and the workpieces can be fixed by the adsorption of the permanent magnet plate. At the same time, the screws are magnetized during the adsorption process, which is more convenient for installation with a screwdriver.

[0023] A rear guardrail 3 is provided at the rear side of the platform 1, and an outer guardrail 2 is provided on one side of the platform 1. The platform 1 is fixedly connected to both the outer guardrail 2 and the rear guardrail 3 through fixing sleeves 9. A front movable guardrail 5 is rotatably connected to the front side position of the upper surface of the platform 1. The platform 1 is connected to the front movable guardrail 5 through a clamping mechanism 8. A through hole 10 is opened at the position corresponding to the clamping mechanism 8 on the upper surface of the platform 1. Four clamping blocks 11 distributed in a circular array are arranged at the outer ring position of the through hole 10 on the upper surface of the platform 1. The clamping mechanism 8 includes a guide post 81. A chuck 85 is fixedly sleeved on the outer part of the guide post 81. A fixing piece 84 is fixed at the bottom end of the guide post 81. A spring 83 connected to the fixing piece 84 is sleeved on the outer part of the guide post 81.

Both ends of the spring 83 are fixed to the pressing piece 82 and the fixing piece 84 by welding respectively. A clamping groove adapted to the clamping block 11 is opened on the lower surface of the chuck 85. The diameter of the guide post 81 is adapted to the inner diameter of the through hole 10. The guide post 81 is fixedly welded to the connecting rod below the front movable guardrail 5. When in use, the operator first pulls up the front movable guardrail 5. During the pulling-up process, the guide post 81 moves upward. During the movement, the contact between the pressing piece 82 and the bottom of the platform is restricted, so that the spring 83 is compressed. At the same time, the chuck 85 is separated from the clamping block 11. At this time, the front movable guardrail 5 is rotated 90 degrees to open the door. After the maintenance personnel enter the platform 1, the front movable guardrail 5 is rotated 90 degrees and then put down. The chuck 85 is engaged with the clamping block 11, effectively ensuring the construction safety of the operator.

[0024] A tool lifting mechanism 7 is installed on the front side of platform 1. The tool lifting mechanism 7 includes a housing 73. A switch 72 is installed on the upper surface of the housing 73. And a disc servo motor 76 is installed at one end position on the front side of the housing 73. A winding wheel 75 is rotatably connected inside the housing 73 at a position corresponding to the disc servo motor 76. And a first guide wheel 71 is rotatably connected to the side of the housing 73 away from the winding wheel 75. A second guide wheel 74 is rotatably connected to the side of the housing 73 at a position on the side of the winding wheel 75. And a lifting block 78 is arranged below the housing 73. A tool box 79 is fixed to the front side of the lifting block 78. And steel cables 77 are fixed to both ends of the upper surface of the lifting block 78. The other ends of the two steel cables 77 are respectively connected to the winding wheel 75 through the first guide wheel 71 and the second guide wheel 74. The transmission end of the disc servo motor 76 penetrates the housing 73 and is connected to the winding wheel 75. Two annular storage grooves are formed on the surface of the winding wheel 75. The two steel cables 77 are respectively wound in the two annular storage grooves. The switch 72 is connected to an external power supply. At the same time, the switch 72 is used to control the forward and reverse rotation of the disc servo motor 76. During use, control the disc servo motor 76 to rotate clockwise to release the steel cable 77 wound on the surface of the winding wheel 75. At this time, under the weight of the tool box 79, the released steel cable 77 will be driven to run downward, thereby realizing the descent. After the descent, the ground personnel can place the tools required by the maintenance personnel in the tool box 79. At this time, control the disc servo motor 76 to rotate counterclockwise, so that the winding wheel 75 winds the steel cable 77 on its surface again, thereby realizing the rise of the tool box 79, which is convenient for taking tools. It solves the problem of inconvenient tool transmission in high-altitude operations and effectively improves work efficiency.

[0025] The working principle of the present invention is as follows: During installation, first weld the first connecting plate 61 to the main beam of the crane, and at the same time weld the second connecting plate 63 to the platform 1. During assembly, only need to hoist the platform 1 to the position of the first connecting plate 61. The connecting block 66 fits with the first connecting plate 61 and can be fixed by bolts, which has the effect of convenient disassembly and assembly, reduces the labor intensity of workers, improves the installation efficiency, and at the same time reduces the risk of high-altitude installation, increases safety protection. In addition, the overall volume of the hoist is reduced by the disassembly and assembly method, which can achieve the effect of convenient transportation and increases the aesthetic degree. Secondly, when the operator uses it, first pull up the front movable guardrail 5. During the pulling-up process, the guide post 81 moves upward. During the movement, the pressing piece 82 is restricted from contacting the bottom of the platform, so that the spring 83 is compressed. At the same time, the chuck 85 is disengaged from the block 11. At this time, rotate the front movable guardrail 5 by 90 degrees to open the door. After the maintenance personnel enter the platform 1, rotate the front movable guardrail 5 by 90 degrees again and lower it. The chuck 85 and the block 11 are engaged, effectively ensuring the construction safety of the operator. Finally, when transmitting tools, during use, control the disc servo motor 76 to rotate clockwise to release the steel cable 77 wound on the surface of the winding wheel 75. At this time, under the weight of the tool box 79, the released steel cable 77 will be driven to run downward, so as to achieve descent. After the descent, the personnel below can place the tools required by the maintenance personnel in the tool box 79. At this time, control the disc servo motor 76 to rotate counterclockwise, so that the winding wheel 75 winds the steel cable 77 on its surface again, so as to achieve the rise of the tool box 79 and facilitate the taking of tools, solving the problem of inconvenient transmission of tools for high-altitude operations and effectively improving the work efficiency.
