Description

Technical Field

[0001] The present invention relates to a modular insulating operation platform and an operation method for all-terrain live working on a distribution network. Background Art

[0002] With the continuous development and progress of society, the scale of distribution network construction is also constantly expanding, and the workload of distribution network operation and maintenance inspection is increasing day by day. When performing high-altitude operations, necessary safety measures need to be adopted. Especially for high-altitude live working, more professional technologies and special live working safety measures are required to ensure the safety of operators. Traditional high-altitude live working usually uses an aerial insulating bucket truck for live working. Due to the limitations of terrain, traffic conditions, and line structures during wiring, sometimes it is difficult for the aerial insulating bucket truck to reach the operation position, resulting in the inability to carry out live working. At this time, an insulating scaffold is generally used for operation. However, the erection efficiency of the insulating scaffold is low, and there is a significant risk of falling from a height during erection, making it impossible to effectively guarantee the personal safety of live working personnel.

[0003] Therefore, in order to improve the erection efficiency, reduce the risk of falling from a height during erection, ensure the personal safety of live working personnel, reduce the labor intensity of the operation, and improve the automation level of live working, it is of great significance to develop a new type of insulating lifting platform.

Detailed implementation manners

[0018] The following further describes the present invention in detail in conjunction with the accompanying drawings and specific implementation manners.

[0019] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0020] As Figures 1 to 14As shown, the present invention is an all-terrain modular insulating working platform for live distribution network working, including an insulating platform 1, a main supporting structure 2, a safety rope, and a ground lifting and building assembly 4 arranged in sequence from top to bottom, the insulating platform 1 is convenient for workers to stand, the insulating platform 1 is arranged on the top of the main supporting structure 2, the main supporting structure 2 bears the weight of the insulating platform 1 and the workers, the main supporting structure 2 includes a plurality of main supporting rods 201 spliced together vertically in sequence, two adjacent main supporting rods 201 are plugged together, each main supporting rod 201 is provided with a ladder rod 209 for workers to climb, the ladder rod is arranged horizontally, and workers climb the insulating platform through the ladder rod; the ground lifting and building assembly 4 is used to lift the main supporting rod 201 upward section by section, so that the insulating platform 1 is lifted upward to the working point; the safety rope 3 is arranged around the insulating platform and connected to the ground. The main supporting structure adopts building block modular construction. There is no need for high-altitude operations during the entire construction process, which can effectively improve the construction efficiency, reduce the risk of falling from heights during construction, ensure the personal safety of personnel working with live wires, reduce the labor intensity of operations, and improve the level of automation of live wire operations.

[0021] In this embodiment, the ground lifting construction component 4 includes a support top plate 401 and a support bottom plate 402 which are parallel and spaced apart from each other. Four vertical support rods 403 distributed in a rectangular shape are fixed between the support top plate 401 and the support bottom plate 402. The vertical support rods are used to connect the support top plate and the support bottom plate into a whole.

[0022] In this embodiment, a lifting plate 404 is arranged parallel between the support top plate 401 and the support bottom plate 402. The lifting plate 404 is driven by a lifting assembly installed at the bottom of the support top plate 401 to rise and fall vertically. A positioning plug-in portion 405 for plugging and cooperating with the lower end of the main support rod 201 is arranged in the middle of the lifting plate 404. When working, the main support rod is inserted into the positioning plug-in portion, the lifting assembly drives the lifting plate to move upward, and the lifting plate drives the main support rod to move upward synchronously, so as to lift the main support rod upward; after one main support rod is lifted upward, the lifting plate moves downward to the initial position, and the next main support rod is installed in the positioning plug-in portion.

[0023] In this embodiment, Figure 12 As shown, the positioning plug part 405 is a cylindrical structure with an open top, which is convenient for inserting and withdrawing the main support rod 201; the positioning plug part 405 is hinged to the hinge part 406 of the support bottom plate 402 through a hinge pin, that is, the positioning plug part can rotate left and right. When in use, the main support rod is inserted, and the positioning plug part is rotated to an inclined state to facilitate the insertion of the main support rod; when withdrawing, the positioning plug part is in a vertical state to facilitate the removal of the main support rod.

[0024] In this embodiment, sliding bearings 407 are respectively arranged at the four top corners of the lifting plate 404. The sliding bearings 407 are slidably sleeved outside the corresponding vertical support rods 403. When the lifting plate moves up and down, the sliding bearings slide along the vertical support rods. By cooperating the sliding bearings with the vertical support rods, the smoothness of the up and down movement of the lifting plate is improved.

[0025] In this embodiment, the lifting assembly includes an electric hoist 408, a fixed pulley 409 and a lifting rope 410. The electric hoist and the fixed pulley are both installed at the bottom of the support top plate. The upper end of the lifting rope 410 bypasses the fixed pulley 409 and is connected to the electric hoist 108, and the lower end of the lifting rope 410 is connected to the lifting plate 404. When the electric hoist 408 winds or releases the lifting rope 410, it drives the lifting plate 404 to slide up and down along the vertical support rod 403. By changing the direction of the lifting rope through the fixed pulley 424, the lifting and lowering of the main support rod are realized.

[0026] In this embodiment, the main support rod 201 is of a tubular structure. A quick-insert connector A202 of a tubular structure is arranged at the lower end of the main support rod 201. The upper end of the quick-insert connector A202 is fixedly inserted into the lower end pipe orifice of the main support rod, and the lower end extends out of the main support rod 201. A locking slot 203 extending radially along its circumferential side wall and a telescopic tongue 204 telescoping radially are arranged on the circumferential side wall of the quick-insert connector A202. The locking slot 203 and the telescopic tongue 204 are distributed oppositely front and back. A quick-insert connector B205 of a tubular structure is arranged at the upper end of the main support rod 201. The lower end of the quick-insert connector B205 is fixedly inserted into the upper end pipe orifice of the main support rod 201, and the upper end extends out of the main support rod. The quick-insert connector B205 is used to be sleeved outside the quick-insert connector A202. A limiting jack 206 is arranged at the rear end of the circumferential side wall of the quick-insert connector B205 to facilitate the insertion of the telescopic tongue 204 after the plug-in fit. After the quick-insert connector A and the quick-insert connector B are plugged and sleeved, by cooperating the telescopic tongue 204 with the limiting jack 206, axial limiting is carried out during operation to prevent the axial separation of the quick-insert connector A and the quick-insert connector B during operation. When two adjacent main support rods are spliced, the quick-insert connector B at the upper end of the main support rod located below is plugged and sleeved with the quick-insert connector A at the lower end of the main support rod located above. The telescopic tongue on the quick-insert connector A is inserted into the limiting jack on the side wall of the quick-insert connector B to realize the connection of the two main support rods. The structure of the telescopic tongue and the limiting jack realizes axial limiting, so that the two main support rods cannot be easily separated axially.

[0027] In this embodiment, a locking slider 411 is arranged in the middle of the front end of the support top plate 401. The locking slider 411 is driven to move forward and backward by a first electric push rod 412 to extend into or out of the locking slot 203. When the locking slider is inserted into the locking slot, the main support rod cannot be lifted upward at this time.

[0028] In this embodiment, a pair of upper and lower radially distributed through holes 207 are formed in the rear end of the circumferential side wall of the quick-insert connector B205. The telescopic tongue 204 is in a horizontal U shape. The upper and lower ends of the telescopic tongue 204 respectively extend into a pair of radially through holes 207. A radially arranged compression spring 208 is connected to the inner side of the telescopic tongue 204. The compression spring 208 pushes the lower end of the telescopic tongue 204 to extend out of the radially through hole 207 and is used to insert into the limit jack 206. A second electric push rod 416 is arranged in the middle of the rear end of the support top plate 401. The second electric push rod 416 is used to push the upper end of the telescopic tongue 204, so that the telescopic tongue 204 moves radially inwards and separates from the limit jack 206, that is: the second electric push rod is used to unlock the connection between the main support pipe sections. When disassembly is required, the second electric push rod extends, the second electric push rod pushes the upper end of the telescopic tongue, and the telescopic tongue moves radially inwards, so that the telescopic tongue separates from the limit jack. At this time, the main support rod located below can be removed.

[0029] In this embodiment, a photoelectric sensor 417 is installed on the top of the support bottom plate 402, and a laser sensor 413 is installed on the bottom of the support top plate 401. The photoelectric sensor 417 is used to detect whether the lifting plate 404 has descended to the initial position. The photoelectric sensor 417 has two signals, namely the rising edge and the falling edge. The laser sensor 413 is used to detect whether the lifting plate 404 has risen to the specified position. Specifically: the photoelectric sensor 417 and the laser sensor 413 are both electrically connected to the electric hoist 408 through the control unit. When the lifting plate 404 moves downwards and is detected by the photoelectric sensor 417 (rising edge signal or falling edge signal), the control unit controls the electric hoist 408 to stop working, so that the lifting plate 404 will not continue to move downwards. When the lifting plate 404 moves upwards and is detected by the laser sensor 413, the control unit controls the electric hoist 408 to stop working, so that the lifting plate 404 will not continue to move upwards. The electric hoist 408 has a rising button 414 and a falling button 415. When the rising button 414 is pressed, the electric hoist 408 winds up the lifting rope 410. At this time, the lifting rope drives the lifting plate to move upwards. When the falling button is pressed, the electric hoist releases the lifting rope, and at this time the lifting plate moves downwards. Specifically: When the main support structure 2 is installed: Press the up button 414, and the electric hoist 408 drives the lifting plate 404 to move upward through the lifting rope 410. When the lifting plate 404 moves upward to the position where the laser sensor 413 gets a signal, the electric hoist 408 stops, the first electric push rod 412 extends, and the locking slider 411 is inserted into the locking slot 203 to lock the main support rod 201 with the locking slider 411. Then press the down button 415, and the lifting plate 404 moves downward. When the lifting plate 404 moves downward to the position where the photoelectric sensor 413 gets a falling edge signal, the electric hoist 408 stops. Place another main support rod on the positioning socket 405 on the lifting plate 404, press the up button 414. When the lifting plate 404 moves upward until the photoelectric sensor 417 loses the rising edge signal (during this process, the main support rod 201 below is spliced with the main support rod 201 above), the electric hoist 408 stops rising, the first electric push rod 412 contracts, so that the locking slider 411 extends out of the locking slot 203, and then the electric hoist 408 continues to drive the lifting plate 404 to move upward. Repeat the above actions in sequence until all the main support rods are installed. When the main support structure 2 is disassembled: Press the down button 415, and the lifting plate 404 drives the whole main support structure 2 to descend. When the photoelectric sensor 417 gets a rising edge signal, the electric hoist 408 stops descending, the first electric push rod 412 and the second electric push rod 416 extend simultaneously. The first electric push rod 412 drives the locking slider 411 to be inserted into the locking chute 203 of the penultimate main support rod 201, and the second electric push rod 416 pushes the telescopic tongue 204 of the penultimate main support rod 201 to separate the telescopic tongue 204 from the limit socket 206 of the lowermost main support rod 201 (at this time, the lowermost main support rod can be separated from the penultimate main support rod). Then the lifting plate 404 continues to descend. After descending to the initial position (the photoelectric sensor 417 gets a falling edge signal), the electric hoist 408 stops, and the lowermost section of the main support rod 201 is removed. After removal, the electric hoist 408 drives the lifting plate 404 to move upward until it rises to the position where the laser sensor 413 gets a signal, and the electric hoist 408 stops. At this time, the quick-insert connector A202 at the lower end of the main support rod 201 is inserted into the positioning socket 405 on the lifting plate 404, and the first electric push rod 412 and the second electric push rod 416 contract simultaneously. Then the lifting plate 404 drives the main support rod 201 to move downward. Repeat the above actions in sequence until all the main support rods are disassembled.

[0030] In this embodiment, a telescopic fixing plate 418 is arranged parallel to the top of the support top plate 401, and vertically arranged telescopic support rods 419 are fixed around the telescopic fixing plate 418. The telescopic support rods 419 slide vertically through the vertical guide sleeve 420 fixed on the support top plate 401 to form a sliding fit. The side wall of the vertical guide sleeve 420 is provided with a first quick release pin 421 for locking the telescopic support rod 419, and the first release pin is used to slide and lock the telescopic support rod. The middle part of the support top plate 401 and the telescopic fixing plate 418 are provided with a clearance hole 422 for facilitating the penetration of the main support rod 201 and the ladder rod 209. Four rubber-coated wheels 423 are distributed around the clearance hole 422 on the telescopic fixing plate 418 and the clearance hole 422 on the support top plate 401. The four rubber-coated wheels 423 are vertically rolling fit with the outer surface of the main support rod 201. The four rubber-coated wheels are used to radially limit the main support rod from the circumferential side to improve the stability of lifting. When in use, the position of the telescopic fixing plate can be adjusted up and down, and after adjustment, the telescopic support rod is locked by the first quick-release pin.

[0031] In this embodiment, the first electric push rod and the second electric push rod are located at the front and rear sides of the clearance through hole of the support top plate, and are fixed to the support top plate by bolts.

[0032] In this embodiment, four foldable leg assemblies 424 are distributed along the circumference between the support top plate 401 and the support bottom plate 402. The four foldable leg assemblies are distributed at the top corners and are supported on the ground by the four foldable leg assemblies.

[0033] In this embodiment, each foldable leg assembly 424 includes a telescopic rod 429 and a leg rod 425. One end of the leg rod 425 is hinged to the support bottom plate 402, and the leg rod can swing up and down around the hinge; a connecting sleeve 426 is slidably sleeved outside the leg rod 425. The connecting sleeve 426 is locked on the leg rod 425 by a first spring pin 427. A rubber foot pad 428 for contacting the ground is provided at the end of the leg rod 425 away from the support bottom plate 402; the telescopic rod 429 includes an outer square tube 430 and an inner square tube 431 that are slidably matched. The upper end of the outer square tube 430 is hinged to the support top plate 401, that is, the telescopic rod can swing up and down around the hinge; a sliding fixed sleeve 432 is fixedly sleeved at the lower end of the outer square tube 430. A second spring pin 433 for locking the inner square tube 431 is provided on the sliding fixed sleeve 432. After the inner square tube is telescoped, it is locked by the second spring pin; the lower end of the inner square tube 431 is hinged to the connecting sleeve 426 via a third spring pin 434. By pulling the third spring pin, the lower end of the inner square tube can be separated from the connecting sleeve, and at this time the entire foldable leg assembly can be folded. Further, the rubber foot pad is connected to the leg rod by a thread. When the ground is uneven, the height of the rubber foot pad is adjusted to keep the ground lifting and building assembly level.

[0034] In this embodiment, in the main support structure 2, a fixed ring 210 is fixedly sleeved outside the uppermost main support rod 201. The fixed ring is fixed to the main support rod 201 by a hoop. Four hook rings 211 evenly distributed in a circle are fixed on the fixed ring 210.
