Description

Technical Field

[0001] The present invention relates to the technical field of line operation and maintenance, and in particular to a mobile platform for distribution line operation and maintenance and a method for using the mobile platform. Background Art

[0002] Transmission line construction is an indispensable part of current power construction, including insulator construction and cable construction, etc. Transmission lines need to be regularly maintained to ensure the normal operation of electricity. However, when inspecting and repairing transmission lines, most people directly fasten safety belts on the cables and then walk on the cables. This not only has a low safety factor, but also has poor stability, which is not conducive to the inspection and maintenance of transmission lines. Patent documents have been developed to improve this.

[0003] For example, Chinese patent CN115377867A discloses a maintenance platform for power transmission line inspection, which includes a station board, two grooves are symmetrically arranged inside the station board, a pick-up piece is arranged at the front middle of the station board, and two limit sleeves are arranged on the external symmetrical sliding sleeve of the station board, and vertical plates are arranged on the upper sides of both ends of the two limit sleeves, a guide piece is arranged between the two vertical plates, and a sunshade piece is arranged between the upper ends of each vertical plate. The maintenance platform for power transmission line inspection enables electricians to move stably on the power transmission line, and the personnel do not need to walk on the power transmission line, thereby improving safety and facilitating personnel to perform better maintenance work on the power transmission line. The maintenance platform can be adjusted according to the distance between the cables and the height of the maintenance personnel themselves, so that it can be stably hung on the cables, which is convenient for personnel to perform maintenance work on the line.

[0004] Although the equipment in the above documents can drive the staff to move on the surface of the cable to facilitate maintenance and repair, it still has many obvious defects in actual use, such as:

[0005] 1. When the equipment moves on the cable surface, it is limited and moved only by the guide wheels on both sides. However, this structural setting makes the equipment's bearing point only at a central point. If the bearing points are different during work, it is easy to cause the station board to flip and shake;

[0006] 2. Whether the equipment is moving or lowering the tube, it needs to be driven manually by the staff. The weight of the equipment itself plus the staff will consume a lot of physical strength and increase the workload.

[0007] Therefore, a mobile platform for distribution line operation and maintenance is now designed to ensure stability and reduce physical exertion to solve such defects. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a mobile platform for distribution line operation and maintenance and a method of using the same, which solves the problem that the prior equipment is unstable and labor-intensive when in use.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: a mobile platform for distribution line operation and maintenance, including a basic mobile mechanism for mobile bearing, and a driving switching mechanism for driving lifting is installed on the surface of the basic mobile mechanism.

[0011] Preferably, the two supporting side frames are fixedly connected to the first support plate on the opposite sides, and the front part of one side of the first support plate is rotatably connected to the polygonal rotating drum by opening, and the surface of the polygonal rotating drum and one side of the first support plate are provided with a first guide wheel, the front and rear sides of the bottom of the first support plate are fixedly connected to the vertical guide plate, and the surface of the vertical guide plate is slidably mounted with a second support plate, one side of the second support plate is rotatably connected to the second guide wheel used in conjunction with the first guide wheel, and the other side of the second support plate is fixedly connected to a threaded sleeve, and one side of the first support plate is rotatably connected to a second threaded rod via a bearing member, and the second threaded rod is threadedly connected to the threaded sleeve.

[0012] Preferably, the front and rear sides of the top of the supporting side frame are slidably installed with lifting rods through openings, the surfaces of the lifting rods and the surfaces of the supporting side frames are provided with limiting slots that cooperate with each other, and the inner sides of the limiting slots are provided with pin blocks, and a top plate is fixedly connected between the top ends of the four lifting rods.

[0013] Preferably, the drive switching mechanism includes a dual-axis motor, and the dual-axis motor is fixedly connected to the front of the load-bearing platform through a bracket, and the two output shafts of the dual-axis motor are fixedly connected to a sleeve rod through a coupling, and a polygonal rod used in conjunction with a polygonal rotating drum is slidably installed on the inner side of the sleeve rod, and a polygonal sleeve used in conjunction with the polygonal rotating drum is installed on the surface of the polygonal rod, and a first spring is fixedly connected between the sleeve rod and the polygonal sleeve.

[0014] Preferably, a transverse push rod is slidably installed on the surface of the supporting side frame through a fixed block, and the opposite ends of the two transverse push rods are fixedly connected to a curved plate, and a second spring is sleeved on the surface of the transverse push rod, and the upper part of one side of the curved plate is fixedly connected to a polygonal resistance rod used in conjunction with the polygonal rotating drum.

[0015] Preferably, the surface of the right side supporting side frame is rotatably connected to a driven rod through a bracket, the surface of the driven rod is fixedly connected to a wire reel, the surface of the wire reel is wound with a cable, and the bottom end of the cable is fixedly connected to a hanging basket, the left side of the right side supporting side frame is fixedly connected to a bearing ring through a bracket, and the bearing ring is sleeved on the surface of the polygonal rod, and pulleys are provided on the right side of the bearing ring and the surface of the driven rod, and the two pulleys are connected by belt transmission.

[0016] The present invention also discloses a method for using a mobile platform for power distribution line operation and maintenance, which specifically comprises the following steps:

[0017] S1. Before use, first manually shake the first threaded rod to drive the two supporting side frames to move synchronously to adjust the spacing. Stop when the spacing between the two supporting side frames matches the distance between the cables on both sides. Then push the two belts to move the multi-angle support rod and the curved plate away from the first guide wheel. At this time, a space appears between the first guide wheel and the multi-angle support rod. Then pass the cable through the space and place it at the bottom of the first guide wheel. When the cables on both sides are at the bottom of the first guide wheel, immediately rotate the second threaded rod. Under the action of the thread of the threaded sleeve, the second support plate is driven up through the vertical guide plate, so that the second guide wheel fits with the first guide wheel. At this time, the cable is clamped by the second guide wheel and the first guide wheel, and then go to step S2.

[0018] S2, when the equipment needs to be moved, the dual-axis motor is started to drive the sleeve rod to rotate. At this time, since the polygonal sleeve is on the inner side of the polygonal rotating drum, the polygonal rod drives the polygonal rotating drum and the first guide wheel to rotate under the drive of the sleeve rod. The rotation of the first guide wheel will drive the equipment to move on the surface of the cable. After moving to the specified position, the dual-axis motor is stopped. At this time, the line maintenance is carried out. When it is necessary to take the components from the bottom, go to step S3;

[0019] S3. First, pull the horizontal push rod to drive the bending plate to insert the polygonal support rod into the inner side of the polygonal rotating drum. After the polygonal support rod enters the inner side of the polygonal rotating drum, push the polygonal sleeve and the polygonal rod out of the inner side of the polygonal rotating drum at the same time. After the polygonal sleeve is pushed out, the other end is docked with the pulley. After the polygonal support rod is docked with the polygonal rotating drum, rotate the handle and clamp the handle with the supporting side frame. At this time, the horizontal push rod is fixed, and then the hanging basket is hooked to the bottom end of the cable. Then start the dual-axis motor and use the polygonal rod to drive the polygonal sleeve to rotate again. At this time, the rotation of the polygonal sleeve can be driven by the pulley and belt. The driven rod and the wire drum are driven to rotate. After the wire drum rotates, the cable can be extended to lower the hanging basket to the ground. After the ground personnel place the tool inside the hanging basket, the driven rod is started again to reverse the wire drum to reel in the cable and pull the hanging basket up again. After the hanging basket is reset, it is removed from the bottom end of the cable, and then the handle is rotated to loosen the horizontal push rod. Under the elastic force of the second spring, the polygonal resistance rod is pushed out from the inside of the polygonal rotating drum, and then the polygonal rod and the polygonal sleeve re-enter the inside of the polygonal rotating drum under the elastic force of the first spring. At this time, the dual-axis motor is started again to drive the equipment to move.

[0020] Preferably, in step S3, the hanging basket can be disassembled from the cable.

[0021] Beneficial Effects

[0022] The present invention provides a mobile platform for distribution line operation and maintenance and a method for using the same. Compared with the existing technology, the mobile platform has the following advantages:

[0023] (1) The mobile platform for distribution line operation and maintenance and the method of using the same, by combining the basic moving mechanism and the drive switching mechanism, the arrangement of the two mechanisms can utilize the dual-axis motor to drive the first guide wheel to rotate, allowing the device to move on the surface of the cable, and the arrangement of multiple sets of first guide wheels and second guide wheels can effectively ensure the overall balance and stability of the device, and can perform power switching when accessories need to be transported, so that the hanging basket can be raised and lowered by the dual-axis motor, without the need for manual driving by the staff, thereby reducing physical exertion and facilitating use.

[0024] (2) The mobile platform for distribution line operation and maintenance and the method of using the mobile platform are characterized by installing a sleeve rod and a polygonal rod on both sides of the dual-axis motor, and providing a polygonal sleeve and a first spring on the surface of the polygonal rod, and using the mobile platform in combination with a polygonal support rod and a polygonal rotating drum. When the hanging basket needs to be raised or lowered, the polygonal support rod can be inserted into the polygonal rotating drum to squeeze the polygonal sleeve to switch power, while fixing the polygonal rotating drum, so that the hanging basket can effectively ensure stability when it is raised or lowered.

[0025] (3) The mobile platform for distribution line operation and maintenance and its use method are achieved by sliding two supporting side frames on both sides of the load-bearing platform and using them in conjunction with a first threaded rod. The arrangement of these structures can adjust the distance between the two supporting side frames, thereby ensuring that the equipment can be applied to lines with different widths.

Stop when the spacing between the two supporting side frames 103 matches the distance between the cables on both sides.

When it is necessary to take components from the bottom, go to step S3; S3, first pull the push rod (206) to drive the curved plate (207) to insert the polygonal support rod (209) into the inner side of the polygonal rotating cylinder (106), and after the polygonal support rod (209) enters the inner side of the polygonal rotating cylinder (106), the polygonal sleeve (204) and the polygonal rod (203) are pushed out of the inner side of the polygonal rotating cylinder (106), and the other end of the polygonal sleeve (204) is connected to the pulley (215) after being pushed out, and the polygonal support rod (209) is pushed out of the inner side of the polygonal rotating cylinder (106). 9) After the connection with the polygonal rotating drum (106) is completed, the handle is rotated to clamp the handle by using the supporting side frame (103), at which time the horizontal push rod (206) is fixed, and then the hanging basket (213) is hooked on the bottom end of the cable (212), and then the double-axis motor (201) is started to drive the polygonal sleeve (204) to rotate again by using the polygonal rod (203), and the rotation of the polygonal sleeve (204) can be driven by the pulley (215) and the belt (216). The transmission of the take-up drum (211) drives the driven rod (210) and the take-up drum (211) to rotate. After the take-up drum (211) rotates, the cable (212) can be extended to lower the hanging basket (213) to the ground. After the ground personnel place the tool inside the hanging basket (213), the driven rod (210) is started again to reverse the take-up drum (211) to rewind the cable (212) and pull up the hanging basket (213). After the hanging basket (213) is reset, it is Remove it from the bottom end of the cable (212), then rotate the handle to loosen the horizontal push rod (206), and push the polygonal support rod (209) out from the inside of the polygonal rotating cylinder (106) under the elastic force of the second spring (208), and then the polygonal rod (203) and the polygonal sleeve (204) re-enter the inside of the polygonal rotating cylinder (106) under the elastic force of the first spring (205), and then start the dual-axis motor (201) again to drive the device to move.

9. The method for using a mobile platform for distribution line operation and maintenance according to claim 8, characterized in that: In the step S3, the hanging basket (213) can be disassembled from the cable (212).
