[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0030] See also Figures 1 to 7 The present invention provides an electric ladder lift for high-altitude power work, which comprises:

[0031] A rectangular frame 1, and reels 1 2 and 2 3 rotatably mounted inside the rectangular frame 1, with a servo motor 4 for driving reel 1 2 to rotate mounted on one side of the rectangular frame 1;

[0032] A transmission mechanism 5 for connecting the reel 1 2 and the reel 2 3 is installed on the other side of the rectangular frame 1;

[0033] The soft ladder 6 is composed of two soft ropes 61 and a plurality of cross bars 62. The cross bars 62 are evenly spaced and installed between the two soft ropes 61. One end of the two soft ropes 61 is fixedly connected to the reel 1 2, and the other end of the two soft ropes 61 is fixedly connected to the reel 2 3. A suspension mechanism 7 is provided on the two soft ropes 61.

[0034] The ladder bucket 8 is evenly provided with four positioning holes 801 , and connecting pieces 9 are installed in the four positioning holes 801 . The ladder bucket 8 is installed on any two adjacent cross bars 62 through the four connecting pieces 9 .

[0035] The suspension mechanism 7 includes a suspension frame 73, which is provided with two groups. The top ends of the two groups of suspension frames 73 are equipped with movable lock buckles 71. The bottom ends of the two groups of suspension frames 73 are rotatably equipped with winding wheels 74 for winding the soft rope 61. The inner side of the winding wheel 74 is equipped with an insert block 75. A distance rod 76 is inserted on the insert block 75. Slots 701 that are plugged into the insert block 75 are opened on both sides of the distance rod 76. Locking bolts 77 are threadedly installed on the distance rod 76, and limit plates 78 are symmetrically installed on both sides of the distance rod 76.

[0036] A limiting groove is formed between the limiting plate 78 and the winding wheel 74 to limit the jumping of the soft rope 61;

[0037] It should be noted that when in use, the soft ladder 6 wound on the reel 1 2 and the reel 2 3 is unwound so that the unwound length is equal to twice the lifting height. After unwound, the movable lock 71 of the suspension mechanism 7 is used to lock it on the high iron tower or steel cable, and the winding wheel 74 is used to limit and fix the soft rope 61 of the soft ladder 6 in the limiting groove composed of the limiting plate 78 and the winding wheel 74. At this time, the soft rope 61 is partially immersed in the limiting groove, and then the operator stands on the ladder bucket 8 and uses the servo motor 4 to drive the reel 1 2 to rotate. The reel 1 2 drives the reel 2 3 to rotate through the transmission mechanism 5, realizing unwinding on one side and winding on the other side, thereby driving the soft ladder 6 to move along the winding wheel 74, and then driving the ladder bucket 8 to move up and down, realizing lifting and lowering, and performing high-altitude operations, making high-altitude lifting and construction convenient, and lifting and climbing safer.

[0038] In the embodiments of the present invention, please refer to Figures 1 to 7 The transmission mechanism 5 includes a gear 1 51 and a gear rack 52. The gear 1 51 is fixedly sleeved on one end of the reel 1 2. The gear rack 52 is fixedly installed on the outside of the rectangular frame 1. An intermediate gear 53 is installed on the gear rack 52. A transmission rod 54 is installed on the gear rack 52 on one side of the intermediate gear 53. A gear 2 55 is fixedly sleeved on the transmission rod 54. A transmission plug rod 56 is slidably inserted in the middle of the transmission rod 54. The reel 2 3 is provided with a socket for plugging with the transmission plug rod 56.

[0039] The gear 1 51 and the gear 2 55 are symmetrically distributed with respect to the intermediate gear 53 and are both meshed with the intermediate gear 53 , and the transmission ratios of the gear 1 51 and the gear 2 55 to the intermediate gear 53 are equal.

[0040] It should be noted that when the transmission mechanism 5 is in use, when the soft ladder 6 needs to be stretched to twice the lifting height, the transmission plug rod 56 is withdrawn from the socket provided in the reel 2 3, and then the adjusting hand wheel 31 is turned to realize unilateral unwinding. After unwinding to an appropriate length, the transmission plug rod 56 is inserted into the socket. In this way, when the servo motor 4 drives the reel 1 2 to rotate, the gear 1 51, the intermediate gear 53 and the gear 2 55 cooperate to drive the reel 2 3 to rotate in the opposite direction, thereby realizing unwinding on one side and rewinding on the other side, thereby realizing lifting and lowering displacement;

[0041] In this embodiment, an adjusting hand wheel 31 is installed at one end of the reel 2 3 .

[0042] In the embodiments of the present invention, please refer to Figures 1 to 7 , a locking screw 72 is threadedly mounted on the movable lock buckle 71;

[0043] It should be noted that after the movable lock buckle 71 is locked on the iron tower or the steel cable, the locking screw 72 is screwed into the movable lock buckle 71 to further fix the lock buckle connection.

[0044] In the embodiments of the present invention, please refer to Figures 1 to 7 The connecting member 9 includes a clamping block 91 of a mating structure. The clamping block 91 is provided with a semi-arc groove 901 for engaging with the cross bar 62. A half screw 92 is installed at one end of the clamping block 91. The half screws 92 of the two clamping blocks 91 are mated and passed through the positioning hole 801 and then threadedly connected with a locking nut 93.

[0045] It should be noted that when installing the ladder bucket 8, the matching block 91 is engaged with the cross bar 62 using the semi-arc groove 901, and then the matching half screw 92 is passed through the positioning hole 801, and then the locking nut 93 is screwed on. When disassembling, only the locking nut 93 needs to be unscrewed, which facilitates quick disassembly and assembly, and facilitates the later replacement of the installation position of the ladder bucket 8.

[0046] The working principle of the electric ladder lift for high-altitude power work provided by this utility model is as follows:

[0047] When in use, the soft ladder 6 wound on the reel 1 2 and the reel 2 3 is unwound, so that the unwound length is equal to twice the lifting height. After unwinding, the movable lock 71 of the suspension mechanism 7 is used to lock it on the iron tower or steel cable at a high place, and the winding wheel 74 is used to limit and fix the soft rope 61 of the soft ladder 6 in the limiting groove composed of the limiting plate 78 and the winding wheel 74. At this time, the soft rope 61 partially sinks into the limiting groove, and then the operator stands on the ladder bucket 8 and uses the servo motor 4 to drive the reel 1 2 to rotate. The reel 1 2 drives the reel 2 3 to rotate through the transmission mechanism 5, realizing unwinding on one side and winding on the other side, thereby driving the soft ladder 6 to move along the winding wheel 74, and then driving the ladder bucket 8 to move up and down, realizing lifting and lowering, and performing high-altitude operations, making high-altitude lifting and construction convenient, and lifting and climbing more safer;

[0048] Furthermore, when installing the ladder bucket 8, the matching block 91 is engaged with the cross bar 62 using the semi-arc groove 901, and then the matching half screw 92 is passed through the positioning hole 801, and then the locking nut 93 is screwed on. When disassembling, only the locking nut 93 needs to be unscrewed, which facilitates quick disassembly and assembly, and facilitates the later replacement of the installation position of the ladder bucket 8.

[0049] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
