Description

Technical Field

[0001] The invention relates to the technical field of tool loading and fixing, and in particular to a device for loading and fixing tools for aerial work. Background Art

[0002] Aerial work refers to various work activities carried out at a height above the ground, usually involving construction, maintenance, cleaning and other work. Since aerial work is dangerous, it is necessary to follow strict safety regulations and operating procedures. Power line maintenance is an important task to ensure the safe, stable and efficient operation of the power system, including regular inspections of power lines, checking whether the insulation, wires, brackets, etc. of the lines are intact, improving inspection efficiency and safety, timely discovering and troubleshooting, using professional equipment to detect the current, voltage and other parameters of the lines, ensuring the normal operation of the lines, etc. For any faults that occur, quickly analyze the causes and take corresponding repair measures. At present, in various types of power line emergency repair and maintenance work, power maintenance personnel often need to carry tools and use tools such as pedals to climb to the height of the poles for aerial work, and then start related emergency repair and maintenance work after arriving at the work position, and carry the tools they need with them.

[0003] The multifunctional aerial work transfer tool with patent publication number CN107311025A is easy to operate and firmly fixed, and can be suitable for various types of tools and equipment of different sizes. Moreover, the device is designed with multiple locks to prevent the tools from falling in mid-air when transferring tools, thereby ensuring safety. The clamping pliers can be pulled apart by a sliding rod, so that they can be fixed more firmly when fixing the rod body or insulators. When it is not necessary to fix the rod body and insulator, the two clamping pliers can be docked into one clamping pliers, which is convenient to use. A tightening locking device is provided above the clamping pliers to play a locking role and ensure the safety of the operation.

[0004] In the process of work of the above-mentioned and similar technical solutions, since the power maintenance personnel carry a large number of tools with them, they need to carry the above-mentioned tools on their backs when working at height, which wastes the physical strength of the power maintenance personnel and increases the work intensity of the power maintenance personnel. In addition, when the power maintenance personnel need to carry a large number of tools but cannot carry them all at once, they can only work by increasing the carrying amount or carrying the tools in batches. However, increasing the carrying amount will increase the physical consumption of the power maintenance personnel and may easily lead to dangerous accidents, while carrying the tools in batches will affect work efficiency. When the power maintenance personnel are working, there will be tools that are inconvenient to operate, which will cause certain interference to the work of the power maintenance personnel.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] A device for loading and fixing tools for aerial work, with a mainboard assembly being provided, the mainboard assembly being carried to a high altitude by an electric maintenance worker, and a bearing assembly and a power connection assembly being left on the ground. When the electric maintenance worker arrives at the working position, the connecting rope inside the mainboard assembly is lowered.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] When power maintenance personnel perform aerial work, they need to carry a large number of tools with them, which wastes their physical strength and increases their work intensity. At the same time, there are potential safety hazards. Tools are prone to falling, which may cause damage to the tools at the very least, or even injure the workers below, resulting in casualties. The technical solution provided by the present application divides the tool loading device into three parts, the first part is the mainboard assembly, the second part is the bearing assembly, and the third part is the power connection assembly, wherein the mainboard assembly and the power connection assembly are detachably electrically connected, and the mainboard assembly is carried by the power maintenance personnel, while the bearing assembly stays on the ground. When the power maintenance personnel carry the mainboard assembly to a high altitude, they fix the mainboard assembly in the air, lower the connecting rope in the mainboard assembly, and connect it to the power connection assembly. Since the specially manufactured connecting rope can form a loop with the power connection component, when the bearing component is fixed on the surface of the connecting rope, the connecting rope can supply power to the bearing component, thereby driving the bearing component to rise and fall, and then lift the tools installed on the bearing component to a high altitude together, or send the tools in the air to the ground for replacement. Since the mainboard component, the bearing component and the power connection component are independent entities, they are quick to disassemble and assemble and easy to use, thereby saving the physical strength of the power maintenance personnel to the greatest extent and improving the protection effect for the power maintenance personnel. In the process of the power maintenance personnel's work, when there are tools or instruments that are inconvenient to operate, the robotic arm can assist in holding the tools. For example, when the power maintenance personnel are not convenient to hold or pick up the tools, the robotic arm can assist in picking up or supporting the tools, thereby assisting the work of the power maintenance personnel.

[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, the present invention provides a technical solution: a loading and fixing device for aerial work tools, comprising a mainboard assembly 1, a bearing assembly 3 and a power connection assembly 5. The mainboard assembly 1 is carried to a high altitude by an electric power maintenance personnel, and the bearing assembly 3 and the power connection assembly 5 are left on the ground. When the electric power maintenance personnel arrive at the working position, the connecting rope 102 inside the mainboard assembly 1 is lowered. Since the connecting rope 102 is composed of an internal power connection inner wire 105 and a wear-resistant skin 106 wrapped around the outer wall of the power connection inner wire 105, a loop can be formed when the connecting rope 102 is connected to the power connection assembly 5. A driving assembly 4 for clamping the connecting rope 102 is provided on the back of the bearing assembly 3. The connecting rope 102 forming a loop supplies power to the driving assembly 4, and a first loading plate 302 and a second loading plate 303 for placing tools are provided on the front of the bearing assembly 3. Under the action of the driving assembly 4, the bearing assembly 3 loaded with tools is The lifting assembly 301 is lifted to the position of the power maintenance personnel, which is convenient for the rapid replacement of tools and the use of the power maintenance personnel; the bearing assembly 3 includes a lifting plate 301, and a mechanical arm 304 is fixedly installed on one side of the lifting plate 301, and the mechanical arm 304 can take the tools on the first loading plate 302 and the second loading plate 303 and interact with the power maintenance personnel, so as to assist the work of the power maintenance personnel. In the process of retracting and releasing the connecting rope 102, the connecting rope 102 is movably limited by the positioning assembly 2 arranged inside the mainboard assembly 1. After the work of the power maintenance personnel is completed, the driving assembly 4 controls the bearing assembly 3 to descend to the ground and releases the clamping of the connecting rope 102. The ground staff disconnects the connection between the connecting rope 102 and the power connection assembly 5, and the power maintenance personnel in the air control the mainboard assembly 1 to retract the connecting rope 102, and carry the mainboard assembly 1 back to the ground to complete the work.

[0032] It should be noted that when the power maintenance personnel carry the mainboard assembly 1 to a high altitude and arrive at the designated position, the mainboard assembly 1 can be fixed at the designated position, and the ground staff can install the tools needed on the first loading plate 302 and the second loading plate 303 respectively. Since the first loading plate 302 and the second loading plate 303 are of different sizes, tools of different sizes can be placed respectively. The robotic arm 304 is controlled by the power maintenance personnel in the air. Since the robotic arm 304 generally has set module data, and the positions of the first loading plate 302 and the second loading plate 303 are fixed, when the power maintenance personnel need tools, they can control the robotic arm 304 at the designated position through a handheld controller to get the tools installed on the first loading plate 302 and the second loading plate 303.

[0033] like Figure 1As shown, the mainboard assembly 1 includes a main box 101, and a winding roller for winding up the connecting rope 102 is rotatably connected between the inner walls at both ends of the main box 101, and the connecting ropes 102 are fixedly connected to the surface of the winding rollers, and a passage is formed under the action of the winding rollers, and the bottom of the connecting ropes 102 are fixedly connected to a counterweight ring 107, which is used to ensure that the connecting rope 102 can reach the ground smoothly and quickly when the connecting rope 102 is released. The bottom outer wall of the counterweight ring 107 is fixedly connected to an electric head 108 electrically connected to the power inner line 105, and the outer wall of the electric head 108 is covered with a protective shell 109 for protecting the electric head 108, and the outer wall of one end of the main box 101 is rotatably connected to a turntable 104 for controlling the winding roller.

[0034] It should be noted that when the power maintenance personnel rotate the turntable 104, the winding roller can be driven to rotate, thereby lowering the connecting rope 102 that is gathered on the outer wall of the winding roller. Under the action of the counterweight ring 107, the connecting rope 102 can be smoothly lowered to the ground, and the protective shell 109 can protect the connecting head 108 to prevent the connecting head 108 from being hit or damaged.

[0035] like Figure 5 As shown, the positioning assembly 2 includes a moving block 201, and a plurality of moving grooves 103 for retracting and releasing the connecting rope 102 are opened at the bottom of the main box 101, the moving blocks 201 are all inserted in the moving grooves 103, and the two sides of the moving block 201 are fixedly connected with a clamping block 205, the inner walls on both sides of the moving groove 103 are opened with a clamping groove 202 adapted to the clamping block 205, and the outer wall at one end of the moving block 201 is fixedly connected with a clamping ring 203 for limiting the connecting rope 102, the outer wall of the connecting rope 102 is opened with an outer groove that can be directly connected to the power-connected inner wire 105, and the outer wall at one end of the moving block 201 is rotatably connected with a limiting ball 204 that contacts the power-connected inner wire 105, during the process of raising and lowering the connecting rope 102, the limiting ball 204 will always be stuck in the outer groove to ensure that the direction of the outer groove is always consistent.

[0036] It should be noted that during the process of retracting and releasing the connecting rope 102, as the winding roller retracts or releases the connecting rope 102, the winding position of the connecting rope 102 on the outer wall of the winding roller will also change. At this time, the laterally movable block 201 and the retaining ring 203 can be used to limit the connecting rope 102 while ensuring that the connecting rope 102 can move laterally as the winding roller is retracted and released, thereby preventing the connecting rope 102 from being pulled. The limiting ball 204 can ensure that the connecting rope 102 always maintains the consistency of the outer groove direction during the process of retraction and release, thereby preventing the connecting rope 102 from being entangled and causing interference with the lifting and lowering of the drive component 4.

[0037] like Figure 7 , Figure 8 and Fig. 9As shown, the driving assembly 4 includes a driving motor 401, and the driving motor 401 is respectively fixedly connected to the outer wall of one side of the lifting plate 301, and the outer wall of the other side of the lifting plate 301 is respectively rotatably connected to the main rotating rod 402 connected to the driving motor 401, and the outer wall of the main rotating rod 402 is fixedly connected to the first limiting plate 403 for clamping the connecting rope 102, and the outer wall of the other side of the lifting plate 301 is fixedly connected to a plurality of second fixing rings 411 and the first fixing ring 408, and the circumferential inner wall of the second fixing ring 411 is rotatably connected to The inner wall of the rotating cylinder 409 and the first fixed ring 408 is provided with a cross bar 407, and the outer wall of one end of the cross bar 407 is set as a threaded structure, and the cross bar 407 is respectively inserted into the outer walls of both ends of the rotating cylinder 409 through threads, and the outer wall of one end of the cross bar 407 is fixedly connected with a power connection block 404, and one end of the power connection block 404 is rotatably connected with a power connection ball 413, the power connection ball 413 contacts the power connection inner wire 105, and transmits electricity to the power connection column 412 fixed on the back of the lifting plate 301, and the power connection column 412 is respectively connected to the driving motor 401.

[0038] It should be noted that after the ground staff connects the power connection head 108 to the power connection component 5, the connecting rope 102 can be placed in the first limit plate 403, and the two cross bars 407 can be driven to move horizontally by rotating the rotating cylinder 409 until the power connection ball 413 contacts the power connection inner wire 105. Since the power connection inner wire 105 forms a current loop under the action of the power connection component 5, the current is guided to the power connection column 412 and the drive motor 401 under the action of the power connection ball 413. Under the action of the power connection ball 413, the drive motor 401 can always be in a power-connected state, thereby ensuring that the drive motor 401 can continue to be in a working state.

[0039] like Figure 8 As shown, the top and bottom of the power connection block 404 are fixedly connected with a second limit plate 405, and the inner walls on both sides of the second limit plate 405 are rotatably connected with an auxiliary rotating rod 406 for cooperating with the main rotating rod 402 to clamp the connecting rope 102.

[0040] It should be noted that when the power-connecting ball 413 contacts the power-connecting inner wire 105, multiple auxiliary rotating rods 406 will contact the connecting rope 102 at the same time and clamp the connecting rope 102 under the action of the main rotating rod 402. When the driving motor 401 drives the main rotating rod 402 to rotate, the lifting plate 301 can be driven to rise and fall along the connecting rope 102. The auxiliary rotating rod 406 and the main rotating rod 402 will contact the connecting rope 102 at the same time and clamp the connecting rope 102. When the main rotating rod 402 rotates, the lifting plate 301 can be raised and lowered. When the main rotating rod 402 does not rotate, the lifting plate 301 can stop and be fixed under the action of friction.

[0041] like Figure 2 As shown, the power connection component 5 includes a power connection box 501, and the top outer wall of the power connection box 501 is provided with a power connection hole 502 adapted to the power connection head 108, the top outer wall of the power connection box 501 is respectively provided with a knob 503 and a display panel 504, and the power connection box 501 is provided with a power cord 505 for connecting to an external power source and charging the power connection box 501 itself.

[0042] like Figure 6 As shown, the back of the main box 101 is fixedly connected with multiple straps 110, hooks 112 and protective rods 111, and the protective rods 111 are made of elastic material, which can provide a certain buffering protection effect for the back of the power maintenance personnel when the power maintenance personnel carry the main box 101.

[0043] like Figure 8 As shown, a plurality of protruding rods 410 are fixedly connected to the circumferential outer wall of the rotating cylinder 409 , and the protruding rods 410 are made of elastic material, so that the ground staff can hold them and rotate the rotating cylinder 409 to control the movement of the cross bar 407 .

[0044] It should be noted that when the power maintenance personnel carry the mainboard assembly 1 to a high altitude and arrive at the designated position, the mainboard assembly 1 can be fixed at the designated position by the hook 112, and the ground workers install the tools to be used on the first loading plate 302 and the second loading plate 303 respectively. Since the first loading plate 302 and the second loading plate 303 are of different sizes, tools of different sizes can be placed respectively. The mechanical arm 304 is controlled by the power maintenance personnel in the air. Since the mechanical arm 304 is generally set with module data, and the first loading plate 302 and the second loading plate 303 are The position is fixed, so when the power maintenance personnel need tools, they can control the mechanical arm 304 through the handheld controller to get the tools installed on the first loading plate 302 and the second loading plate 303 at the specified position. When the power maintenance personnel rotates the turntable 104, the winding roller can be driven to rotate, so as to lower the connecting rope 102 wound on the outer wall of the winding roller. Under the action of the counterweight ring 107, the connecting rope 102 can be smoothly lowered to the ground. In the process of winding and releasing the connecting rope 102, as the winding roller winds or releases the connecting rope 102, the winding position of the connecting rope 102 on the outer wall of the winding roller will also be changed. The connecting rope 102 is changed. At this time, the movable block 201 and the clamping ring 203 that can be moved laterally can limit the connecting rope 102 while ensuring that the connecting rope 102 can move laterally with the winding and releasing of the winding roller to prevent the connecting rope 102 from being pulled, and the limiting ball 204 can ensure that the connecting rope 102 always maintains the consistency of the outer groove direction during the winding and releasing process. After the ground staff connects the power connection head 108 with the power connection component 5, the connecting rope 102 can be placed in the first limiting disk 403, and the two cross bars 407 can be driven to move laterally by rotating the rotating cylinder 409 until the power connection ball 413 is aligned with the power connection component 5. The inner wire 105 is in contact with the power connection component 5, and since the power connection inner wire 105 forms a current loop under the action of the power connection component 5, the current is directed to the power connection column 412 and the drive motor 401 under the action of the power connection ball 413, thereby ensuring that the drive motor 401 can be continuously in a working state. When the power connection ball 413 contacts the power connection inner wire 105, the plurality of auxiliary rotating rods 406 will contact the connecting rope 102 at the same time, and clamp the connecting rope 102 under the action of the main rotating rod 402. When the drive motor 401 drives the main rotating rod 402 to rotate, the lifting plate 301 can be driven to rise and fall along the connecting rope 102.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
