DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0022] First embodiment:

[0023] See also Figures 1 to 5 The present invention provides a live working hoisting platform, including a locking mechanism, a connecting rod 101, a connecting plate 102, a supporting plate 103, an adjusting mechanism, a wire rope 104 and a hook, the locking mechanism includes a fixing block 105, a first locking block 106 and a second locking block 107, the adjusting mechanism includes a winding member, a first supporting block 108, a second supporting block 109 and a protective chamber 110, the winding member includes a winding motor 111, a rotating rod 112 and a limiting plate 113, and the hook includes a hook body 114 and a closing body 115.

[0024] In this embodiment, the lifting platform is locked on the electric pole 116 by the locking mechanism, and then the length of the wire rope 104 is adjusted by the adjusting mechanism, so that the height of the hook can be adjusted. When the hook reaches the height of the ground 119, the transformer is hung on the hook, and the length of the wire rope 104 is adjusted again until the height of the wire rope 104 reaches the height of the support plate 103, and then the transformer is removed from the hook and placed on the support plate 103 to achieve the lifting of the transformer. During the entire lifting process, the lifting platform used is small in size and light in weight, which makes it easy to transport the lifting platform to the position of the electric pole 116 to be operated, solving the technical problem that the existing lifting platform for live operation is large in size and heavy in weight, making it inconvenient to transport the lifting platform to the position of the electric pole 116 to be operated.

[0025] Among them, the locking mechanism is used to lock the connecting rod 101 on the electric pole 116, the connecting rod 101 is located on the side of the locking mechanism away from the electric pole 116, the connecting plate 102 is arranged at the upper end of the connecting rod 101, the support plate 103 and the connecting plate 102 are detachably connected through the fixing pin shaft 117, the adjusting mechanism is used to adjust the length of the wire rope 104 extending from the support plate 103, the wire rope 104 is located below the support plate 103, and the hook is arranged on the side of the wire rope 104 away from the electric pole 116, and the length of the wire rope 104 can be adjusted, so that the height of the hook can be adjusted.

[0026] Secondly, the fixed block 105 is arranged outside the connecting rod 101, the first locking block 106 and the second locking block 107 are both movably connected to the fixed block 105, and the first locking block 106 and the second locking block 107 are connected by a chain 118, and the fixed block 105, the first locking block 106, the second locking block 107 and the chain 118 are jointly arranged outside the electric pole 116. Through the coordinated use of the fixed block 105, the first locking block 106, the second locking block 107 and the chain 118, the connecting rod 101 can be limited and fixed outside the electric pole 116, thereby realizing the limited fixation of the lifting platform outside the electric pole 116.

[0027] Again, the winding member is used to wind the wire rope 104, the first support block 108 and the second support block 109 are both provided with a support plate 103 below, and the wire rope 104 is located in the first support block 108 and the second support block 109, the protective chamber 110 is detachably connected to the second support block 109, and is located below the second support block 109, so that the protective chamber 110 can be removed from below the second support block 109.

[0028] At the same time, the winding motor 111 is arranged on the ground 119, the rotating rod 112 is connected to the output end of the winding motor 111, and the side of the wire rope 104 away from the hook is arranged on the rotating rod 112, and the limiting plate 113 is arranged on the end of the rotating rod 112 away from the winding motor 111, the output end of the winding motor 111 is connected to the rotating rod 112, and drives the rotating rod 112 to rotate along its own axis, so as to drive the wire rope 104 outside the rotating rod 112 to be wound or unwound on the winding motor 111, and the limiting plate 113 is arranged outside the rotating rod 112, and the limiting plate 113 limits the winding position of the wire rope 104 outside the rotating rod 112 to prevent the wire rope 104 from slipping out of the rotating rod 112 during the winding process.

[0029] In addition, each of the first support block 108 and the second support block 109 has a rotating groove 120, and the first fixed pulley 121 and the second fixed pulley 122 are movably arranged in the rotating grooves 120 of the first support block 108 and the second support block 109, respectively, and the steel wire rope 104 is arranged outside the first fixed pulley 121 and the second fixed pulley 122. By setting the first fixed pulley 121 and the second fixed pulley 122, the moving direction of the steel wire rope 104 can be changed, and the movement of the steel wire rope 104 will not cause obstruction to the transformer suspended on the hook.

[0030] In addition, a reinforcing rod 123 is removably provided in the first support block 108, and a fixing rod 124 is removably provided on a side of the reinforcing rod 123 close to the connecting rod 101. The fixing rod 124 is detachably connected to the protection chamber 110 and is arranged outside the connecting rod 101. The first support block 108 and the reinforcing rod 123 as well as the reinforcing rod 123 and the fixing rod 124 are connected via a connecting pin 125. The supporting stability of the support plate 103 can be enhanced by the coordinated use of the reinforcing rod 123 and the fixing rod 124. The reinforcing rod 123 is detachable to facilitate the storage of the reinforcing rod 123.

[0031] Finally, the hook body 114 and the closing body 115 are movably connected via a connecting shaft 126. The hook body 114 has a groove 127, and the closing body 115 has a protrusion 128. The protrusion 128 cooperates with the groove 127 and is inserted into the groove 127 to achieve the closure of the hook body 114 by the closing body 115. The closing body 115 is rotated. When the protrusion 128 of the closing body 115 is embedded in the groove 127 of the hook body 114, the hook body 114 is completely closed, so that the object suspended by the hook body 114 cannot be moved out from the opening of the hook body 114. When the protrusion 128 of the closing body 115 is moved out of the groove 127 of the hook body 114, the hook body 114 is opened, so that the object suspended by the hook body 114 can be moved out from the opening of the hook body 114.

[0032] When using a live working lifting platform of the present embodiment, when it is necessary to install the transformer on the electric pole 116, first, install the support plate 103 on the connecting plate 102 in sequence, install the protection chamber 110 under the second support block 109, and install the reinforcing rod 123 between the first support block 108 and the fixing rod 124, thereby completing the installation of the entire lifting platform, and then, bring the lifting platform to the upper part of the electric pole 116, and then through the coordinated use of the fixing block 105, the first locking block 106, the second locking block 107 and the chain 118, the connecting rod 101 can be limited and fixed outside the electric pole 116, thereby realizing the limited fixation of the lifting platform outside the electric pole 116 and realizing the locking of the lifting platform on the electric pole 116.

[0033] After the hoisting platform is locked to the electric pole 116, the winding motor 111 is started, so that the power output from the output end of the winding motor 111 drives the rotating rod 112 to rotate along its own axis, thereby driving the steel wire rope 104 outside the rotating rod 112 to be wound or unwound on the winding motor 111. First, the steel wire rope 104 is unwound, so that the length of the steel wire rope 104 is continuously increased, so that the hook is continuously moved downward. When the hook reaches the height of the ground 119, the closing body is rotated. 115, the protrusion 128 of the closing body 115 is moved out of the groove 127 of the hook body 114, so that the hook body 114 is opened, and the rope tied to the transformer is inserted into the hook body 114 from the opening of the hook body 114, and then the closing body 115 is rotated. When the protrusion 128 of the closing body 115 is embedded in the groove 127 of the hook body 114, the hook body 114 is completely closed, so that the rope cannot be moved out of the opening of the hook body 114, and the transformer can be hung on the hook.

[0034] Afterwards, the wire rope 104 is reeled in, so that the length of the wire rope 104 is continuously shortened, thereby causing the hook to continuously move upward. During the reeling process of the wire rope 104, the limit plate 113 can limit the reeling position of the wire rope 104 outside the rotating rod 112 to prevent the wire rope 104 from slipping out of the rotating rod 112 during the reeling process. When the height of the wire rope 104 reaches the height of the support plate 103, the hook body 114 is opened. Open, remove the lifting rope tied to the transformer from the hook body 114, and then place the transformer on the support plate 103, so that the entire lifting process of the transformer can be realized. During the entire lifting process, the lifting platform used is small in size and light in weight, which makes it easy to transport the lifting platform to the position of the electric pole 116 to be operated, solving the technical problem that the existing live working lifting platform is large in size and heavy in weight, making it inconvenient to transport the lifting platform to the position of the electric pole 116 to be operated.
