Description

Technical Field

[0001] This invention relates to the field of positioning platform technology, and in particular to a three-dimensional positioning platform for substation workers. Background Technology

[0002] A three-dimensional positioning platform is a platform with positioning and movement functions, including a three-dimensional high-precision positioning and movement device for machining test pieces, or a lifting and moving platform used in maintenance. In substation engineering, three-dimensional positioning platforms are mostly lifting devices used in equipment management and maintenance.

[0003] Currently, most lifting devices used in substation projects are hydraulic lifting platforms. During use, the stability of these platforms deteriorates due to wear and aging of the lifting frame, causing workers to sway and fall. When workers stand on top of the lifting platform, the platform is not easily extended due to the load-bearing capacity. At this time, the small area of ​​the lifting platform makes it inconvenient to carry out maintenance operations. Furthermore, the soil near power poles in substations is relatively loose, and the lifting platform is not easy to fix, making it prone to tipping over.

[0004] To address the aforementioned issues, a three-dimensional positioning platform for substation workers is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a three-dimensional positioning platform for substation workers, which solves the problems in the background art where the stability of the lifting platform deteriorates due to wear and aging of the lifting frame, causing workers to sway and fall during use. When workers stand on the top of the lifting platform, the platform is not easy to extend due to the load. At this time, the area of ​​the lifting platform is small, making it inconvenient to carry out maintenance operations on the platform. In addition, the soil near the power poles in the substation is relatively loose, and the lifting platform is not easy to fix, making it prone to tipping over.

[0013] Furthermore, the first clamping assembly includes a sliding plate fixedly connected to the output end of the hydraulic device, and sliding rods fixedly connected to the four corners of the other side of the sliding plate, with the other end of the sliding rods extending outward through the base and connected to a sliding column.

[0014] Furthermore, the first clamping assembly also includes a connecting plate fixedly connected to the base, and the connecting plate is provided in two sets. A rotating shaft is rotatably connected between the two sets of connecting plates. A clamping block is rotatably connected on the rotating shaft, and the clamping block is provided in two sets.

[0015] Furthermore, the support platform is provided with extension grooves corresponding to the first extension plate and the second extension plate. The first extension plate and the second extension plate are respectively provided with intersecting first plate grooves and second plate grooves. Both the first extension plate and the second extension plate are provided with second limiting grooves that pass through from left to right.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. A three-dimensional positioning platform for substation workers, wherein by moving a lever, the rocker arm is disengaged from the meshing wheel. Rotating the rocker arm then drives the winding roller to release the wire rope. When the worker stands on top of the support platform, the hydraulic lifting frame is activated to raise the platform. The platform stops when it is obstructed by the wire rope. At this point, the hydraulic actuator is activated, and the slider on the actuator pushes the limit block to move after contacting the inner wall of the first limit groove. As the limit block moves, the first and second racks simultaneously engage the two sets of meshing wheels. The mechanism operates on the principle of a ratchet, where the meshing wheel and the gear ring engage the meshing wheel under the action of the spring. As the meshing wheel rotates, it drives the winding roller to tighten the wire rope through the gear ring and the rotating shaft. At this time, the tension of the wire rope is restricted by the hydraulic system, ensuring that the wire rope can only be tightened. This reduces the swaying amplitude of the support platform when it is raised, increasing stability. When the support platform needs to be lowered, the hydraulic system returns to its original position. After the hydraulic lifting frame descends, the gear ring separates from the meshing wheel by moving the lever. Then, rotating the rocker arm allows the wire rope to be wound and wound up.

[0020] 2. A three-dimensional positioning platform for substation workers, wherein after the hydraulic lifting frame is raised, when the worker stands on the top of the support platform, the motor is started. The output end of the motor rotates by meshing two sets of bevel gears through end face gears. When the bevel gears rotate, they mesh with the first extension plate and the second extension plate respectively, causing the first extension plate and the second extension plate to extend to both sides inside the extension groove, and finally stop due to the obstruction of the limiting crossbar. This increases the standing area on the top of the support platform. Furthermore, since the first extension plate and the second extension plate slide inside the support platform, they are not affected by the worker's gravity before unfolding, requiring less driving force and having high unfolding efficiency.

[0021] 3. A three-dimensional positioning platform for substation workers, wherein when the hydraulic actuator extends, the output end of the hydraulic actuator pushes the sliding plate to move before pushing the limit block to move. When the sliding plate moves, it pushes the sliding rod to move. The sliding column on the sliding rod slides in the arc groove inside the clamping block, so that the clamping block can clamp the power pole. Linkage is achieved during the tightening of the wire rope. When the first extension plate and the second extension plate extend, the first extension plate drives the first U-shaped plate to move through the first sliding plate, and the second extension plate drives the second U-shaped plate to move through the second sliding plate. When the first extension plate and the second extension plate move to the maximum distance, the second sliding plate extends into the fitting groove inside the first U-shaped plate, realizing the clamping of the upper part of the power pole. Together with the first clamping component, the bottom of the power pole is clamped, realizing the clamping of the upper and lower parts, further improving stability. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To address the technical problem of decreased stability of lifting platforms due to wear and aging of the lifting frame during use, such as... Figure 1-5 As shown, the following preferred technical solutions are provided:

[0035] A three-dimensional positioning platform for substation workers includes a lifting platform body 1, a stabilizing mechanism 2 and an extension mechanism 4 disposed within the lifting platform body 1, and a clamping mechanism 3 disposed on one side of the lifting platform body 1. The lifting platform body 1 includes a base 11 and a hydraulic lifting frame 12 disposed on the top of the base 11, and a support platform 13 disposed on the top of the hydraulic lifting frame 12. The stabilizing mechanism 2 includes a first driving component 21 disposed inside the base 11 and a limiting component 22 disposed inside the base 11. The stabilizing mechanism 2 also includes winding rollers 23 disposed at the four corners inside the base 11, and rotating shafts 232 are fixedly connected between two corresponding sets of winding rollers 23. Steel wire ropes 231 are wound on the winding rollers 23, and the steel wire ropes 231 pass through the base 11 and extend upward. The other end of the steel wire ropes 231 is disposed at the bottom of the support platform 13. The limiting component 22 includes a meshing wheel 221 rotatably connected to the rotating shaft 232, and a gear ring 223 slidably connected to the rotating shaft 232.

[0036] The first drive assembly 21 includes a hydraulic actuator 211 fixedly connected inside the base 11. A limit block 212 is slidably connected to the outer wall of the output end of the hydraulic actuator 211. A first limit groove 2121 is provided inside the limit block 212. A slider 2111 is fixedly connected to the outer wall of the output end of the hydraulic actuator 211, and the slider 2111 is slidably connected inside the first limit groove 2121. The first drive assembly 21 also includes a first rack 213 and a second rack 214 fixedly connected to both sides of the limit block 212. The first rack 213 is engaged with the top of a set of meshing wheels 221, and the second rack 214 is engaged with the bottom of another set of meshing wheels 221. Teeth 222 are provided on the meshing wheels 221 near the toothed ring 223. The winding roller 23 also includes a fixing plate 224 fixedly connected to the rotating shaft 232. A spring 225 is fitted on the rotating shaft 232 and is located between the fixing plate 224 and the gear ring 223. The gear ring 223 is provided with a surrounding groove 2231. A lever 2232 is provided on the base 11 and is rotatably connected to the top of the base 11. The bottom of the lever 2232 passes through the base 11 and extends into the groove 2231. Rockers 233 are rotatably connected to both sides of the front end of the base 11 and are connected to the winding roller 23 at the front end of the base 11 via shafts. The other end of the wire rope 231 is fixedly connected to a fixing bolt 234, which is distributed at the four corners of the bottom of the support platform 13.

[0037] Specifically, by moving the lever 2232, the rocker arm 233 is disengaged from the meshing wheel 221. Then, rotating the rocker arm 233 causes the winding roller 23 to release the wire rope 231. When the worker stands on top of the support platform 13, the hydraulic lifting frame 12 is activated to raise the support platform 13. Once the support platform 13 is raised, it stops due to the resistance from the wire rope 231. At this point, the hydraulic actuator 211 is activated. The slider 2111 on the hydraulic actuator 211 pushes the limiting block 212 to move after contacting the inner wall of the first limiting groove 2121. As the limiting block 212 moves, the first rack 213 and the second rack 214 simultaneously mesh with the two sets of meshing wheels. When 221 rotates, a ratchet mechanism is formed between the meshing wheel 221 and the gear ring 223. At this time, under the action of the spring 225, the gear ring 223 meshes with the meshing wheel 221. When the meshing wheel 221 rotates, it drives the winding roller 23 to tighten the wire rope 231 through the gear ring 223 and the rotating shaft 232. At this time, the tension of the wire rope 231 is restricted by the hydraulic device 211, so that the wire rope 231 can only be tightened. When the support platform 13 needs to be lowered, the hydraulic device 211 returns. After the hydraulic lifting frame 12 is lowered, the gear ring 223 is separated from the meshing wheel 221 by moving the lever 2232. At this time, the lever 233 can be rotated to wind and rewind the wire rope 231.

[0038] To address the technical problem of the lifting platform being difficult to extend due to the load-bearing capacity when workers are standing on top, such as... Figure 7-9 As shown, the following preferred technical solutions are provided:

[0039] The extension mechanism 4 includes a first extension plate 41 and a second extension plate 42 movably disposed on both sides of the support platform 13, and a second drive assembly 43 disposed at the bottom of the support platform 13. The support platform 13 is provided with extension grooves 131 corresponding to the first extension plate 41 and the second extension plate 42. The first extension plate 41 and the second extension plate 42 are respectively provided with intersecting first plate grooves 411 and second plate grooves 421. The first extension plate 41 and the second extension plate 42 are both provided with second limiting grooves 412 that pass through from left to right. The support platform 13 is provided with a limiting crossbar 413 that passes through the second limiting groove 412. The limiting crossbar 413 is slidably connected to the second limiting groove 412. The bottom of the first extension plate 41 and the second extension plate 42 are both provided with toothed grooves 435.

[0040] The second drive assembly 43 includes a motor 431 fixedly connected to the bottom of the support platform 13. The output end of the motor 431 passes through the bottom of the support platform 13 and extends upward. An end face gear 432 is fixedly connected to the output end of the motor 431. A rotating rod 433 is fixedly connected to one side of the end face gear 432 inside the support platform 13. A bevel gear 434 is rotatably connected to the rotating rod 433. There are two sets of bevel gears 434. The top of the bevel gears 434 meshes with the tooth grooves 435 at the bottom of the first extension plate 41 and the second extension plate 42, respectively. The bevel gears 434 mesh with the top of the end face gear 432. The two sets of bevel gears 434 are located on both sides of the top of the end face gear 432, respectively.

[0041] Specifically, after the hydraulic lifting frame 12 is raised, when the staff stands on the top of the support platform 13, the motor 431 is started. The output end of the motor 431 rotates by meshing two sets of bevel gears 434 through the end face gear 432. When the bevel gears 434 rotate, they mesh with the first extension plate 41 and the second extension plate 42 respectively, so that the first extension plate 41 and the second extension plate 42 extend to both sides inside the extension groove 131, and finally stop due to the obstruction of the limit crossbar 413, thereby increasing the standing area on the top of the support platform 13.

[0042] To address the technical challenges of securing lifting platforms in areas with loose soil near utility poles within substations, such as... Figure 6 and Figure 10 As shown, the following preferred technical solutions are provided:

[0043] The clamping mechanism 3 includes a first clamping assembly 31 disposed on one side of the base 11, and a second clamping assembly 32 movably disposed on one side of the support platform 13. The second clamping assembly 32 includes a first sliding plate 3211 fixedly connected to the bottom side of the first extension plate 41, and a first U-shaped plate 3212 fixedly connected to the other end of the first sliding plate 3211. The second clamping assembly 32 also includes a second sliding plate 3221 fixedly connected to the top of the second extension plate 42, and a second U-shaped plate 3222 fixedly connected to the other end of the second sliding plate 3221. The first clamping assembly 31 includes components fixedly connected to the hydraulic unit 21. The output end has a sliding plate 314, and the other four corners of the sliding plate 314 are fixedly connected to sliding rods 315. The other end of the sliding rods 315 extends outward through the base 11 and is connected to a sliding column 3151. The second clamping assembly 32 includes a second sliding groove 322 provided on the top of the support platform 13 and a first sliding groove 321 provided on one side of the support platform 13. The second sliding plate 3221 is slidably connected in the second sliding groove 322, and the first sliding plate 3211 is slidably connected in the first sliding groove 321. The middle two sides of the first U-shaped plate 3212 are provided with fitting grooves 3213 corresponding to the second U-shaped plate 3222.

[0044] The first clamping assembly 31 also includes a connecting plate 311 fixedly connected to the base 11, and two sets of connecting plates 311 are provided. A rotating shaft 312 is rotatably connected between the two sets of connecting plates 311. A clamping block 313 is rotatably connected to the rotating shaft 312, and two sets of clamping blocks 313 are provided. An arc-shaped groove 3131 is provided on both the upper and lower sides of the clamping block 313, and a sliding column 3151 is slidably connected inside the arc-shaped groove 3131.

[0045] Specifically, when the hydraulic actuator 211 extends, the output end of the hydraulic actuator 211 pushes the sliding plate 314 to move before pushing the limit block 212 to move. When the sliding plate 314 moves, it pushes the sliding rod 315 to move. The sliding column 3151 on the sliding rod 315 slides in the arc groove 3131 in the clamping block 313, so that the clamping block 313 can clamp the utility pole. This achieves linkage during the tightening of the wire rope 231. When the first extension plate 41 and the second extension plate 42 extend, the first extension plate 41 drives the first U-shaped plate 3212 to move through the first sliding plate 3211, and the second extension plate 42 drives the second U-shaped plate 3222 to move through the second sliding plate 3221. When the first extension plate 41 and the second extension plate 42 move to the maximum distance, the second sliding plate 3221 extends into the fitting groove 3213 inside the first U-shaped plate 3212 to clamp the upper end of the utility pole.
