[0002] Overhead power lines are an important part of power grid construction. During overhead power line construction, workers usually need to work on top of power poles. Since the equipment that individuals can carry is limited, when workers need to change equipment, they have to climb down from the power poles to change equipment. This greatly increases the workload of the workers and affects the efficiency of the work. Summary of the Invention

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a power grid construction walking system is provided, including a base plate, the base plate including a first semi-ring plate and a second semi-ring plate arranged opposite to each other, the first semi-ring plate and the second semi-ring plate being hinged at one end, the other ends of the first semi-ring plate and the second semi-ring plate being movably connected, a clearance hole for avoiding power poles is provided between the first semi-ring plate and the second semi-ring plate, a plurality of walking frames are evenly arranged around the clearance hole at the upper end of the base plate, and a walking wheel and a first drive motor for driving the walking wheel to rotate are provided at one end of the walking frame facing the central axis of the clearance hole.

[0005] In one possible implementation, the walking frame includes a first block connected to the base plate. The upper end of the first block has a first through hole along a horizontal direction toward the central axis of the clearance hole. A first rod slides through the first through hole. A horizontal plate is provided at one end of the first rod toward the clearance hole. Longitudinal plates are provided on both sides of the horizontal plate. The walking wheel is rotatably connected between two of the longitudinal plates via a rotating shaft. A first drive motor is connected to the outside of one of the longitudinal plates and is driven by the rotating shaft. A first spring passes through the first rod and is located between the horizontal plate and the first block.

[0006] In one possible implementation, the end of the first rod away from the relief hole passes through the first through hole and extends to the outside of the first through hole. The first rod is provided with a plurality of protrusions of the same length as the protrusions in the circumferential direction. The sidewall inside the first through hole is provided with a plurality of long grooves of the same length as the first through hole in the circumferential direction corresponding to the plurality of protrusions.

[0007] In one possible implementation, the first block is slidably connected to the base plate, and the base plate is provided with a drive assembly for driving the first block away from or towards the central axis of the clearance hole.

[0008] In one possible implementation, the lower part of the first block is provided with a slider, and the upper end of the base plate is provided with a groove corresponding to the slider. The slider is slidably connected in the groove. The driving assembly includes baffles arranged on both sides of the first block along the length direction of the groove.

The first rod passes through the first through groove, and a retaining ring is fitted on the first rod and the retaining ring is located in the first through groove. When the first rod moves, the retaining ring approaches the first proximity switch. When the first proximity switch closes, the second drive motor rotates forward, driving the first block to move closer to the clearance hole. When the first rod moves, the retaining ring approaches the second proximity switch.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Please see Figures 1 to 2The power grid construction walking system provided by the present invention will now be described. The power grid construction walking system includes a base plate 1, which includes a first semi-ring plate 11 and a second semi-ring plate 12 arranged opposite to each other. The first semi-ring plate 11 and the second semi-ring plate 12 are hinged at one end and movably connected at the other end. A clearance hole 103 for avoiding power poles is provided between the first semi-ring plate 11 and the second semi-ring plate 12. A plurality of walking frames 2 are evenly arranged around the clearance hole 103 on the upper end of the base plate 1. A walking wheel 3 and a first drive motor 31 for driving the walking wheel 3 to rotate are provided at one end of the walking frame 2 facing the central axis of the clearance hole 103.

[0032] Compared with the prior art, the power grid construction walking system provided by the present invention, when in use, firstly, the movable connection ends of the first half-ring plate 11 and the second half-ring plate 12 are opened, and the first half-ring plate 11 and the second half-ring plate 12 are rotated to separate their movable ends. Then, the first half-ring plate 11 and the second half-ring plate 12 are respectively placed on the power pole, and then the first half-ring plate 11 and the second half-ring plate 12 are rotated to connect their movable ends, so that the power pole is placed in the clearance hole 103 and the walking wheel 3 on the walking frame 2 abuts against the power pole. By starting the first drive motor 31, the walking wheel 3 is driven to rotate, which can drive the base plate 1 to move up and down on the power pole, transporting equipment and materials for workers working on the power pole, reducing the labor intensity of workers and improving work efficiency.

[0033] In some embodiments, please refer to Figures 1 to 4 Both the first semi-ring plate 11 and the second semi-ring plate 12 have a first overlapping portion 101 that cooperates with each other at their hinge ends. The first overlapping portion 101 has a first through hole that runs vertically through it. A hinge shaft 14 is inserted into the first through hole. Both ends of the hinge shaft 14 have flanges 141 to prevent the hinge shaft 14 from separating from the first overlapping portion 101. Both the first semi-ring plate 11 and the second semi-ring plate 12 have a second overlapping portion 102 that cooperates with each other at their movable connection ends. The second overlapping portion 102 has a second through hole that runs vertically through it. A bolt 16 is inserted into the second through hole. A nut 17 is threaded onto the bolt 16. The second overlapping portion 102 is fastened between the bolt 16 and the nut 17. The first semi-ring plate 11 and the second semi-ring plate 12 are movably connected by the bolt 16 and the nut 17.

[0034] To facilitate the transfer of the base plate 1 during operation, casters 13 are provided at the lower end of the base plate 1. In this embodiment, there are four casters 13, which are arranged in two groups on the first semi-ring plate 11 and the second semi-ring plate 12 respectively. At the same time, a traction part is also provided on the base plate 1. The traction part is used to connect with the traction equipment. In this embodiment, the traction part is a traction hole 15 that passes through the middle of the hinge shaft 14. In use, a traction rope can be threaded into the traction hole 15 and then connected to the traction equipment.

[0035] In practical operations, some utility poles with variable diameter designs may be encountered. To enable the power grid construction walking system provided by this invention to travel on variable diameter utility poles, the walking frame 2 of this invention is configured as follows, please refer to... Figures 1 to 7 Four walking frames 2 are evenly distributed on the base plate 1. Each walking frame 2 includes a first block 4 connected to the base plate 1. The upper end of the first block 4 has a first through hole along the horizontal direction towards the central axis of the clearance hole 103. A first rod 5 slides through the first through hole. A horizontal plate 51 is provided at one end of the first rod 5 facing the clearance hole 103. Longitudinal plates 52 are provided on both sides of the horizontal plate 51. The walking wheel 3 is rotatably connected between two longitudinal plates 52 via a rotating shaft 32. A first drive motor 31 is connected to the outside of one of the longitudinal plates 52 and is driven by the rotating shaft 32. The first rod 5... A first spring 6 is installed at the top, located between the horizontal plate 51 and the first block 4. In application, the first spring 6 is always in a compressed state, so that the traveling wheel 3 always abuts against the utility pole. When the outer diameter of the utility pole increases, the traveling wheel 3 pushes the first rod 5 to slide away from the utility pole in the first through hole, thereby compressing the first spring 6 to adapt to the increase in the outer diameter of the utility pole. When the outer diameter of the utility pole decreases, the first spring 6, which is in a compressed state, releases its elastic force to push the first rod 5 to slide closer to the utility pole in the first through hole, thereby extending the first spring 6 to adapt to the decrease in the outer diameter of the utility pole.

[0036] In this embodiment, the end of the first rod 5 away from the clearance hole 103 passes through the first through hole and extends to the outside of the first through hole. It should be noted that, in application, the length of the first rod 5 outside the first through hole is much larger than the difference in diameter of the power pole. At the same time, in order to prevent the first rod 5 from rotating when sliding in the first bucket, multiple protrusions 501 of the same length as the first rod 5 are provided in the circumference of the first rod 5. Multiple matching long grooves are provided in the circumference of the side wall of the first through hole corresponding to the multiple protrusions 501. The length of the long groove is the same as the length of the first through hole. In use, the protrusions 501 are slidably connected in the long groove. The long groove and the protrusions 501 cooperate to restrict the rotation of the first rod 5 and improve the stability of the structure.

[0037] In practical applications, when the outer diameter of the utility pole changes, to prevent the traveling wheel 3 from experiencing difficulty in moving or slipping, it is necessary to maintain the pressure exerted by the traveling wheel 3 on the utility pole within a certain stable range. To achieve this objective, in this embodiment, please refer to... Figures 5 to 7 The first block 4 is slidably connected to the base plate 1. The base plate 1 is provided with a drive assembly 7 for driving the first block 4 away from or towards the central axis of the clearance hole 103. Specifically, a slider 41 is provided at the lower part of the first block 4, and a groove is provided at the upper end of the base plate 1 corresponding to the slider 41. The slider 41 is slidably connected in the groove. The drive assembly 7 includes baffles 73 arranged on both sides of the first block 4 along the length of the groove. A lead screw 72 is rotatably connected between the two baffles 73. The lead screw 72 passes through the lower part of the first block 4 and is threadedly connected to the first block 4. A second drive motor 71 is provided on the outer side of one of the baffles 73. The drive end of the second drive motor 71 is connected to the lead screw 72 for transmission. In this embodiment, the cross-section of both the groove and the slider 41 is T-shaped. In use, the T-shaped structure design of the groove and the slider 41 cooperates with each other to prevent the first block 4 from separating from the base plate 1.

[0038] Furthermore, the upper end of the first block 4 is provided with a first through groove 42 along a direction perpendicular to the first through hole. A first proximity switch 81 and a second proximity switch 82 are respectively provided on the two side walls of the first through groove 42. The first proximity switch 81 is located on the side wall of the first through groove 42 near the traveling wheel 3, and the second proximity switch 82 is located on the other side wall. The first proximity switch 81 is electrically connected to the second drive motor 71 via a controller, and the second proximity switch 82 is also electrically connected to the second drive motor 71 via a controller. In this embodiment, the first rod 5 extends laterally through the first through groove 42. On the portion of the first rod 5 located within the first through groove 42… The assembly includes a retaining ring 9, which is fixedly connected to the first rod body 5. In application, when the outer diameter of the utility pole decreases, the first rod body 5, under the elastic force of the first spring 6, moves relative to the first block 4 towards the clearance hole 103. This causes the first spring 6 to lengthen and release some of its elastic force, resulting in a decrease in the resistance of the traveling wheel 3 against the utility pole. Consequently, the friction between the traveling wheel 3 and the utility pole decreases, making slippage more likely. To prevent this problem, when the first spring 6 releases its elastic force and lengthens to a certain extent, the retaining ring 9 on the first rod body 5 is positioned close to the first proximity switch 81, causing the first proximity switch 81 to close. The controller then controls the second... When the drive motor 71 rotates forward, the second motor drives the first block 4 to move closer to the clearance hole 103 via the lead screw 72. This causes the first rod 5 to move relative to the first block 4 closer to the clearance hole 103, compressing the first spring 6. This limits the further release of the spring force from the first spring 6, preventing the traveling wheel 3 from slipping due to insufficient spring force. Similarly, when the outer diameter of the utility pole increases, the first rod 5 moves relative to the first block 4 away from the clearance hole 103 under the action of the spring force of the first spring 6. This causes the first spring 6 to be compressed and shortened, increasing its spring force. This results in a greater resistance force between the traveling wheel 3 and the utility pole, thus making the traveling wheel 3 more stable against the utility pole. Increased friction between the piles can lead to difficulty in walking. To prevent this, when the first spring 6 is compressed to the first degree, the retaining ring 9 on the first rod 5 is positioned close to the second proximity switch 82, causing the second proximity switch 82 to close. The controller then controls the second drive motor 71 to reverse. The second motor drives the first block 4 to move away from the clearance hole 103 via the lead screw 72, causing the first rod 5 to move away from the clearance hole 103 relative to the first block 4. This allows the first spring 6 to relax, thus limiting further compression of the first spring 6 and preventing excessive elasticity from causing the walking wheel 3 to have difficulty walking.

[0039] Optionally, we set the compression of the first spring 6 to be optimal when the retaining ring 9 is located in the middle of the first through groove 42. In order to ensure that the first spring 6 can be reset to the optimal state with each adjustment of the second drive motor 71, the present invention is configured as follows, please refer to [link to relevant documentation]. Figures 7 to 8Mounting slots 43 are provided on both sides of the first through slot 42 at the upper end of the first block 4. Both mounting slots 43 are connected to the first through slot 42. A first electromagnet 44 and a second electromagnet 45 are installed in the two mounting slots 43 respectively. A third proximity switch 83 and a fourth proximity switch 84 are also provided on the two side walls of the first through slot 42 respectively. A fifth proximity switch 85 is provided in the middle of the bottom of the first through slot 42. The first electromagnet 44, the third proximity switch 83 and the fifth proximity switch 85 are connected in series in the first circuit. The second electromagnet, the fourth proximity switch 84 and the fifth proximity switch 85 are connected in series in the second circuit. The first circuit and the second circuit are connected in parallel to the same power supply. In this embodiment, the third proximity switch 83 and the fourth proximity switch 84 are normally open switches, and the fifth proximity switch 85 is a normally closed switch. The retaining ring 9 has grooves 901 on both sides of its axial direction. A first baffle 91 and a second baffle 92 are respectively provided in the grooves 901. A tension spring 902 is provided between the first baffle 91, the second baffle 92 and the corresponding grooves 901. The first electromagnet 44, the third proximity switch 83 and the first baffle 91 are all located on the same side of the first proximity switch 81. The second electromagnet 45, the fourth proximity switch 84 and the second baffle 92 are all located on the same side of the second proximity switch 82.

[0040] In this embodiment, when the outer diameter of the utility pole decreases, the first spring 6 extends and releases its elastic force, causing the retaining ring 9 to move towards the first proximity switch 81. When the retaining ring 9 moves close to the first proximity switch 81 and the third proximity switch 83, the first proximity switch 81 and the third proximity switch 83 close simultaneously. The closing of the third proximity switch 83 connects the first circuit, energizing the first electromagnet 44 to generate magnetic force. The first electromagnet 44 attracts the first baffle 91, causing the first baffle 91 to adhere to the side wall of the first through groove 42, thus blocking both the first proximity switch 81 and the third proximity switch 83. The closing of the first proximity switch 81 starts the second drive motor 71, driving the first block 4 to move towards the relief hole 103, adjusting the compression of the first spring 6, causing the retaining ring 9 to move towards the center of the first through groove 42. During the movement of the retaining ring 9 towards the center of the first through groove 42, the first retaining plate 91 is separated from the retaining ring 9 due to the magnetic force of the first electromagnet 44. The first retaining plate 91 is attracted to the side wall of the first through groove 42, forming a continuous shield against the first proximity switch 81 and the third proximity switch 83, keeping the first proximity switch 81 and the third proximity switch 83 in a continuously closed state. When the retaining ring 9 moves to the center of the first through groove 42 and approaches the fifth proximity switch 85, the first circuit is broken, the first electromagnet 44 loses its magnetic force, and the first retaining plate 91 is reset to the groove 901 on the same side of the retaining ring 9 under the action of the tension spring 902. The first proximity switch 81 is disconnected due to the shielding effect of the first retaining plate 91, and the second drive motor 71 stops operating. At this time, the first spring 6 is in the optimal compression state.

[0041] When the outer diameter of the utility pole increases, the first spring 6 is compressed, increasing its elastic force. This causes the retaining ring 9 to move towards the second proximity switch 82. When the retaining ring 9 moves close to the second proximity switch 82 and the fourth proximity switch 84, both switches close simultaneously. The closing of the fourth proximity switch 84 connects the second circuit, energizing the second electromagnet 45 and generating magnetic force. The second electromagnet 45 attracts the second baffle 92, causing it to adhere to the side wall of the first through groove 42, thus blocking both the second and fourth proximity switches 82 and 84. The closing of the second proximity switch 82 activates the second drive motor 71, driving the first block 4 to move away from the clearance hole 103. This adjusts the compression of the first spring 6, causing the retaining ring 9 to move relative to the center of the first through groove 42. Because the second baffle 92 is subjected to the magnetic force of the second electromagnet 45, during the movement of the retaining ring 9 toward the middle of the first through groove 42, the second baffle 92 will separate from the retaining ring 9. The second baffle 92 is attracted to the side wall of the first through groove 42, forming a continuous blockage of the second proximity switch 82 and the fourth proximity switch 84, so that the second proximity switch 82 and the fourth proximity switch 84 are in a continuously closed state. When the retaining ring 9 moves to the middle of the first through groove 42 and approaches the fifth proximity switch 85, the second circuit is broken, the second electromagnet 45 loses its magnetic force, and the second baffle 92 is reset to the groove 901 on the same side of the retaining ring 9 under the action of the tension spring 902. The second proximity switch 82 loses the blockage of the second baffle 92 and becomes open. The second drive motor 71 stops operating. At this time, the first spring 6 is in the optimal compression state.
