Description

Technical Field

[0001] This utility model belongs to the technical field of live-line working platforms, specifically a power distribution live-line working platform. Background Technology

[0002] In the power industry, especially in live-line work on power distribution lines, work platforms are indispensable equipment. While existing work platforms can meet some basic operational requirements, they suffer from several technical deficiencies in design and function, affecting operational safety and efficiency.

[0003] Many traditional work platforms have complex or inflexible movement mechanisms, resulting in lengthy and labor-intensive moves to the work site. These platforms often require manual operation or auxiliary equipment, increasing operating costs and wasting human resources. Furthermore, due to inadequate stability adjustment functions on some platforms, workers are susceptible to swaying caused by uneven ground or rapid movement when performing high-altitude work, increasing safety risks.

[0004] Secondly, existing work platforms often lack stability in their lifting design. When operators need to lift or lower the equipment, they often encounter problems with the platform swaying or tilting during the process, especially under heavy loads or complex working conditions. This unstable lifting characteristic not only affects work efficiency but may also pose a threat to the safety of operators. Significant shaking may cause tools or equipment to fall, resulting in injury or equipment damage.

[0005] To address this, those skilled in the art have proposed a live-line power distribution platform designed to facilitate the adjustment of the overall device's movement or fixed state, thereby improving work efficiency and enhancing the stability of lifting and lowering. Utility Model Content

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] Example 1: This utility model provides a live-line working platform for power distribution, including: a base assembly 100, which serves as the bottom of the overall device for movement and support; a lifting assembly 200, which is installed on the upper end of the base assembly 100 to stably lift the platform; and a platform assembly 300, which is installed on the upper end of the lifting assembly 200 for live-line work.

[0029] Depend on Figure 2As shown, the base assembly 100 also includes a frame 101, with a sealing plate 102 installed between the frames 101 to form a closed space. Support legs 103 are fixedly installed around the lower end of the frames 101. A first motor 104 is installed on the outside of the sealing plate 102. A bidirectional screw 105 is fixedly installed at the output end of the first motor 104 and inside the sealing plate 102. Slide rods 106 are fixedly provided on both sides of the bidirectional screw 105 inside the sealing plate 102. Both sides of the threaded section of the bidirectional screw 105 have The threaded connection includes a threaded slider 107, which is designed as an inverted "convex" shape. Sliding posts 108 are fixedly installed on both sides of the upper end of the threaded slider 107. The sliding posts 108 are slidably mounted on the slide rod 106. Adjusting rods 109 are movably mounted on both sides of the lower end of the threaded slider 107. Fixing blocks 110 are movably mounted on the other end of the adjusting rods 109. A first base plate 111 is fixedly installed on the lower end of the fixing block 110. Pulleys 112 are fixedly installed around the lower end of the first base plate 111.

[0030] As can be seen from the above, by starting the first motor 104, the threaded sliders 107 on both sides of the threaded section of the bidirectional screw 105 are guided and limited by the slide rod 106, and move simultaneously to both ends or the middle. At this time, the adjusting rod 109 drives the first base plate 111 to rise or fall, causing the pulley 112 to rise or fall. In practical applications, the live-line working platform needs to be moved to the work location and fixed there. When the entire working platform needs to be moved, the motor is started to rotate forward, and the threaded sliders 107 move simultaneously to the middle of the bidirectional screw 105. The adjusting rod 109 drives the pulley 112 to fall until the pulley 112 touches the ground. During this process, the support legs 103 gradually leave the ground, allowing the entire working platform to move. When the entire work platform needs to be fixed, the starter motor reverses, and the threaded slider 107 moves simultaneously to both ends of the bidirectional screw 105. The adjusting rod 109 drives the pulley 112 to rise until the pulley 112 is off the ground. During this process, the support legs 103 gradually contact the ground, allowing the entire work platform to be fixed at the work site via the support legs 103. This allows for free adjustment of the platform's overall movement or fixed state, making it widely applicable and convenient to use.

[0031] Example 2: This example is basically the same as the previous example, except that... Figure 3 and Figure 4As shown, the lifting assembly 200 also includes a second base plate 201 fixedly installed on the upper end of the frame 101. Two sets of lower shaft seats 202 are fixedly installed on the front side of the second base plate 201. A first fixed rotating shaft 203 is rotatably arranged between the first shaft seats. A first support arm 204 is fixedly installed on the first fixed rotating shaft 203. A first tail side shaft seat 205 is provided on the inner side of the other end of the first support arm 204. An upper slider connecting plate 206 is fixedly installed on the upper end of the first tail side shaft seat 205. H-shaped upper sliders 207 are fixedly installed on both sides of the upper end of the upper slider connecting plate 206. The H-shaped upper sliders 207 are slidably arranged on two sets of upper slide rails 208 respectively.

[0032] Two sets of lower slide rails 209 are fixedly installed on the tail side of the second base plate 201. H-shaped lower slide blocks 210 are slidably mounted on the lower slide rails 209. A lower slide block connecting plate 211 is fixedly connected to the upper end of the H-shaped lower slide block 210. Second tail side bearings 212 are fixedly installed on both sides of the upper end of the lower slide block connecting plate 211. A lead screw 220 connecting shaft 213 is fixedly installed between the second tail side bearings 212. A limit block 214 is fixedly installed on the upper end of the second base plate 201 and behind the lead screw 220 connecting shaft 213. The lead screw 220 connecting shaft 213 passes through the second tail side bearings 212, and second support arms 215 are movably installed at both ends. A second fixed rotating shaft 216 is movably arranged between the other ends of the second support arm 215. Two sets of upper shaft seats 217 are arranged on the second fixed rotating shaft 216 and located inside the second support arm 215. A fixed seat 218 is fixedly connected to the middle of the upper end of the second base plate 201. A second motor 219 is installed on the front side of the fixed seat 218. A lead screw 220 is fixedly connected to the output end of the second motor 219. A connecting shaft 213 is threadedly connected to the lead screw 220. A third fixed rotating shaft 221 is movably arranged through the first tail side shaft seats 205. Both ends of the third fixed rotating shaft 221 are fixedly installed on the first support arm 204.

[0033] Two sets of first support beams 222 are provided between the first support arms 204, and two sets of second support beams 223 are provided between the second support arms 215. A fourth fixed rotating shaft 224 is installed and connected through the middle of the first support arms 204 and the second support arms 215.

[0034] As can be seen from the above, by starting the second motor 219, the connecting shaft 213 of the lead screw 220 moves on the lead screw 220. During the movement, the H-shaped lower slider 210 slides on the lower slide rail 209. At this time, the second support arm 215 gradually rises, thereby driving the first support arm 204 to rise as well, driven by the fourth fixed rotating shaft 224. During the rise of the first support arm 204, the H-shaped upper slider 207 moves on the upper slide rail 208. That is, during the rise or fall, the H-shaped upper slider 207 and the H-shaped lower slider 210 move in the same direction, thereby driving the platform assembly 300 to rise or fall.

[0035] Depending on the specific application requirements, multiple sets of first support arms 204 and second support arms 215 can be configured to increase the lifting height. During operation, the first support arms 204 and second support arms 215 are effectively supported and assisted by the first support beam 222 and the second support beam 223. The overall structure of the lifting assembly 200 makes it more stable and smooth during lifting.

[0036] Example 3: This example is basically the same as the previous example, except that... Figure 5 As shown, the platform assembly 300 also includes a third base plate 301 fixedly mounted on the upper end of the upper slide rail 208 and the upper end of the upper shaft seat 217. A protective plate 302 is provided around the upper perimeter of the third base plate 301, and an opening / closing door 303 is provided on one side of the protective plate 302. A latch 304 is provided on the opening / closing door 303 for locking with the protective plate 302. The protective plate 302, the opening / closing door 303, and the third base plate 301 are made of insulating material. Access to and from the platform is via the opening / closing door 303, and the latch 304 locks the opening / closing door 303 to the protective plate 302, forming a protective space.
