Description

Technical Field

[0001] The invention relates to the technical field of electric power towers, and in particular to a lifting device and a method for lifting an upper and lower electric power tower. Background Art

[0002] Power towers, also known as high-voltage power line towers, are tall structures used to support and erect high-voltage power lines. They play a vital role in the power system, ensuring that electricity can be efficiently and safely transmitted from power plants to various users. In addition to erecting high-voltage power lines, power towers are also often used as communication stations, various types of communication signals, and microwave station signal transmission.

[0003] At present, the main way for workers to go up and down power towers is to wear safety ropes and climb up and down the towers. The entire climbing process will consume the workers' physical strength. When the workers climb to the top of the tower, they will be exhausted or physically weak, which may lead to safety problems in subsequent work. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a lifting device and method for lifting up and down an electric tower. When the electric tower is lifted up and down by the lifting device, the entire process is automatically lifted and lowered by means of an insulating rope engaged with an inner engaging tooth ring and an outer engaging tooth ring, thereby not consuming much physical strength of the workers. The workers are then fully physically fit when working at high altitudes, effectively reducing the probability of safety accidents caused by physical problems.

[0005] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0007] An inner engaging toothed ring is installed at the upper limit position of the outer ring of the driving wheel, and an outer engaging toothed ring used in conjunction with the inner engaging toothed ring is installed at the upper limit position of the inner wall of the engaging chamber;

[0008] There is a meshing gap between the inner meshing tooth ring and the outer meshing tooth ring that can completely mesh with the insulating rope, wherein the outer meshing tooth ring has a rope-leading gap, the insulating rope is introduced from the rope-leading gap and is led out from the rope-leading gap after being wound around the meshing gap once, and the insulating rope located at the meshing gap is completely meshed and fixed, and the insulating rope is a nylon rope;

[0009] There are also multiple hanging rings fixed on the outer wall of the main box frame; after the staff wears a safety belt and connects the hook on the safety belt with the hanging ring, the staff follows the lifting device to go up and down the power tower synchronously.

[0010] By adopting the above scheme, when the lifting device is used to go up and down the power tower, the entire process is automatically lifted and lowered by the insulating rope engaged by the inner engaging tooth ring and the outer engaging tooth ring, so it will not consume much physical strength of the workers. Then the workers will have plenty of physical strength when working at high altitudes, effectively reducing the probability of safety accidents caused by physical problems; secondly, the lifting device has a light weight of only 11-13 kilograms, and its size is small and easy to carry.

[0011] As a preferred embodiment of the lifting device for the upper and lower towers of an electric tower, the inner side of the inner interlocking gear ring and the outer side of the outer interlocking gear ring are fixed with multiple limiting protrusions distributed in a circumferential array; the inner interlocking gear ring is interference fit with the outer wall of the driving wheel through the limiting protrusions, and the outer interlocking gear ring is interference fit with the inner wall of the interlocking chamber through the limiting protrusions.

[0012] By adopting the above scheme, in order to facilitate the disassembly and replacement of the inner and outer bite gear rings, both are designed to be detachable. Once the teeth of the inner or outer bite gear rings are worn, they should be replaced in time.

[0013] As a preferred embodiment of the lifting device for the upper and lower towers of an electric power tower, the opening of the engaging chamber is detachably sealed with a box cover by means of screws.

[0014] With the above solution, in order to facilitate the opening of the bite chamber, a detachable box cover is installed at its opening. When the inner bite gear ring or the outer bite gear ring needs to be replaced, the box cover can be removed for easy replacement.

[0015] As a preferred embodiment of the lifting device for the upper and lower towers of an electric power tower, a counterweight block for balancing the weight of the motor is detachably fixed to the outer side of the box cover by screws; wherein, protective shells covering the motor and the counterweight block are respectively installed on both sides of the main box frame by screws.

[0016] By adopting the above solution, in order to make the center of gravity of the lifting device located in the middle, a counterweight block is added to maintain balance with the motor, so that the lifting device will be more stable during lifting.
