DETAILED DESCRIPTION

[0016] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0017] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0018] like Figures 1 to 5 As shown, a rotary pole climbing platform for power distribution maintenance provided by an embodiment of the present invention includes a platform 9, which includes a connecting platform 91 and a manned platform 92. The manned platform 92 can be formed into a square frame by a bracket, and an iron sheet is covered on the square frame to form a cage with an upper opening formed by welding multiple sections of steel bars. Of course, the manned platform 92 is not limited to a square shape, but can also be other shapes such as a circle, and the material can also be selected from other materials.

[0019] The platform 9 is provided with a slideway 2, which is matched with the gear ring 1. The gear ring 1 is arranged through the slideway 2, and the gear ring 1 is partially sleeved in the slideway 2. The gear ring 1 can slide in the slideway 2, and the slideway 2 is arc-shaped.

[0020] The platform 9 is provided with a first electric motor 8 , one end of the output shaft of the first electric motor 8 is fixedly connected to a first transmission rod 7 , the first transmission rod 7 is connected to a first gear 6 , and the first gear 6 is provided in the slideway 2 .

[0021] The power of the first electric motor 8 is large enough to drive the platform 9 to rotate. The first electric motor 8 can also realize forward and reverse rotation, so that the platform 9 can be quickly adjusted to a suitable position.

[0022] The platform 9 and the first electric motor 8 are fixedly connected, and of course other connection methods such as snap-on connection can also be used to ensure that the first electric motor 8 can drive the platform 9 to rotate after starting.

[0023] The teeth on the gear 1 can be engaged with the teeth on the first gear 6, so that the first gear 6 can rotate around the gear ring 1 without getting stuck or deviating from the track. The first transmission rod 7, the first gear 6 and the gear ring are made of rigid materials or other high-strength materials to ensure that they will not break during operation.

[0024] The gear ring 1 includes a first arc-shaped rack 101 and a second arc-shaped rack 102, which are detachably connected. Two sets of fixing blocks 12 are fixedly connected to the first arc-shaped rack 101 and the second arc-shaped rack 102, and the fixing blocks 12 are connected by screws and nuts.

[0025] The first arc-shaped rack 101 and the second arc-shaped rack 102 can be spliced ​​into a circular gear ring 1, and the splicing needs to be tightly fitted so that the teeth of the outer wall are evenly arranged so that the platform 9 will not be stuck or derailed when rotating.

[0026] The connection method of the first arc-shaped rack 101 and the second arc-shaped rack 102 is not limited to screw connection, and other detachable connection methods such as snap connection can also be used. It is only necessary to ensure that the joints are tightly fitted and will not fall apart easily.

[0027] The inner walls of the first arc-shaped rack 101 and the second arc-shaped rack 102 are both movably connected with a clamping plate 3 , a hole is opened in the middle of the clamping plate 3 , and a roller 4 is arranged in the hole.

[0028] The roller 4 is made of a material with high friction such as rubber, so that it has enough friction when climbing the pole and will not slide off the pole. The roller 4 can also adopt other shapes, such as a multi-faceted structure, to ensure that its friction is large enough and will not slide off when climbing the pole.

[0029] A driving assembly 5 is disposed inside the first arc-shaped rack 101 and the second arc-shaped rack 102 . The driving assembly 5 includes a second electric motor 51 . The output end of the second electric motor 51 is fixedly connected to a second transmission rod 52 . The second transmission rod 52 is connected to a third gear 53 .

[0030] The two ends of the roller 4 are fixedly connected with a rotating shaft 10 , the rotating shaft 10 is connected with a second gear 11 , and the second gear 11 is meshed with the third gear 53 .

[0031] The rotating shaft 10 is cylindrical and is connected to a second gear 11 made of rigid material or other high-strength material, so it will not break easily. Other structures such as bearings can be set at the connection between the rotating shaft 10 and the splint 3 to reduce the resistance encountered by the roller 4 when rotating, increase the climbing speed, and reduce the wear of the device.

[0032] Cylinders 13 are disposed in the first arc-shaped rack 101 and the second arc-shaped rack 102 , and movable ends of the cylinders 13 are connected to the clamping plate 3 .

[0033] The role of the cylinder 13 here is to give enough pressure to the splint 3, and then apply it to the roller 4, so that there is enough friction between the roller 4 and the climbing pole. Therefore, the strength of the cylinder 13 will be very high, so as not to cause the cylinder to explode due to excessive pressure. Of course, other things can be selected to replace the cylinder 13, such as a hydraulic rod or the like that can give enough pressure to the splint 3.

[0034] The inner walls of the two groups of clamping plates 3 are rotatably connected with a plurality of rolling balls 14, wherein the rolling balls 14 are used to assist the device from falling off when the device is climbing a pole.

[0035] The working principle of the present invention is as follows: When the device is moved up and down, the second electric motor 51 is controlled to start, and the second electric motor 51 drives the second transmission rod 52 to rotate, and the third gear 53 connected to the second transmission rod 52 rotates accordingly, driving the second gear 11 to rotate, and the rotating shaft 10 also rotates, and then the roller 4 can roll. Since the cylinder 13 applies pressure to the splint 3, the roller 4 connected to the splint 3 is also subjected to pressure, and then there is enough friction between the roller 4 and the pole to drive the device to move up and down. When it moves to a suitable height, the second electric motor 51 is controlled to be turned off, and the device can be fixed at the current position.

[0036] When the device moves to a suitable height, the operator controls the first electric motor 8 to start, and the first electric motor 8 rotates through the first transmission rod 7 to drive the first gear 6 to rotate, and the first gear 6 rotates around the gear ring 1, driving the platform 9 to rotate. When it rotates to a suitable position, the first electric motor 8 is controlled to be turned off, and the platform 9 will stop rotating, thereby being fixed in a suitable position for the operator to use for maintenance.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
