Description

Technical Field

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

[0002] Power towers, also known as high-voltage transmission towers, are tall structures used to support and install high-voltage power lines. They play a vital role in the power system, ensuring the efficient and safe transmission of electricity from power plants to consumers. In addition to supporting high-voltage power lines, power towers are also commonly used as communication stations and for transmitting various communication and microwave signals.

[0003] At present, the main way for workers to go up and down power towers is to wear safety ropes manually 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 moving up and down an electric tower. When moving up and down an electric tower using the lifting device, the entire process is automatically lifted and lowered by means of an insulating rope engaged by an inner interlocking gear ring and an outer interlocking gear ring. Therefore, the workers will not consume much physical strength. The workers will then have plenty of physical strength when working at high altitudes, effectively reducing the probability of safety accidents caused by physical problems.

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

[0006] A lifting device for an upper and lower power tower comprises a main box frame, an engaging chamber is defined within the main box frame, a drive wheel is rotatably mounted within the engaging chamber, and the drive wheel is driven to rotate by a motor mounted on the outer wall of the main box frame, and the motor is powered by a rechargeable battery mounted on the outer bottom of the main box frame;

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

[0008] There is an engagement gap between the inner and outer engagement rings that can fully engage the insulating rope. The outer engagement ring has a rope-leading notch. The insulating rope is introduced through the rope-leading notch, loops around the engagement gap once, and then is led out from the rope-leading notch. The insulating rope at the engagement gap is fully engaged and fixed. 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 and outer interlocking gear rings, so it does not consume much physical strength of the workers. Then the workers are physically strong 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 compact and easy to carry.

[0011] As a preferred embodiment of a lifting device for the upper and lower towers of an electric power 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] With the above solution, 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 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 outside 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.

[0017] As a preferred embodiment of a lifting device for an electric power tower, a rope restraint frame is detachably fixed to the outer wall of the main box frame by screws; a vertically arranged rope restraint seat is installed in the middle of the rope restraint frame, and the rope restraint seat is provided with two guide holes one distributed vertically, wherein the insulating rope is passed through the guide holes one, and the positions of the guide holes one correspond to the positions of the rope guide notches of the outer engaging gear ring;

[0018] A horizontally arranged rope restraint seat 2 is installed above and below the rope restraint frame respectively. A guide hole 2 is opened on the rope restraint seat 2, wherein the insulating rope is passed through the guide hole 2; wherein, at least two groups of rope restraint seats 2 are respectively arranged above or below the rope restraint frame.

[0019] By adopting the above solution, in order to further constrain the insulating rope, the insulating rope is passed through the first guide hole and the second guide hole. In this way, during lifting, the insulating rope is constrained in multiple guide holes, which makes the lifting more reliable.

[0020] A method for ascending and descending an electric power tower, wherein the method uses the above-mentioned lifting device for ascending and descending an electric power tower to ascend and descend an electric power tower, and the specific operating steps are as follows:

[0021] S1. Lowering the insulating rope from the top of the power tower to the ground, and then threading the insulating rope into the lifting device;

[0022] S2. When threading the insulating rope, first thread the insulating rope from top to bottom into the second guide hole and the first guide hole above the rope restraint frame. At this time, the insulating rope is just located at the rope guide notch of the outer engaging tooth ring.

[0023] S3. Start the motor, and drive the driving wheel to rotate. Under the meshing transmission of the inner meshing gear ring and the outer meshing gear ring, the insulating rope is meshed once at the meshing interval and then led out from the rope lead notch.

[0024] S4. The drawn insulating rope is then passed from top to bottom through the first guide hole below the rope restraint frame and the second guide hole below the rope restraint frame, and the bottom end of the insulating rope is fixed to the ground, thereby completing the installation of the lifting device;

[0025] S5. After the worker puts on the safety belt and connects the hook on the safety belt to the hanging ring, the worker starts the motor to rotate forward, and then rises synchronously with the lifting device to the top of the power tower, thus completing the lifting work for the worker;

[0026] S6. When the staff descends, repeat the above steps and the staff starts the motor to reverse, thus completing the staff's descent.

[0027] Among them, the insulating rope is wound onto a reel installed on the top of the power tower. The reel is connected to the rocker installed on the ground through a traction rope. The insulating rope can be lowered by rotating the rocker. The way of controlling the reel transmission through the rocker is like the rocker mechanism for raising and lowering the national flag.

[0028] After adopting the above technical solution, the beneficial effects of the present invention are:

[0029] 1. When using this lifting device to go up and down the power tower, the entire process is automatically lifted and lowered by the inner and outer interlocking gear rings interlocking the insulating rope, so it does not consume much physical strength of the workers. The workers are then fully energized when working at heights, effectively reducing the probability of safety accidents caused by physical problems. Secondly, the lifting device is light in weight, only 11-13 kilograms, and its compact size makes it easy to carry.

[0030] 2. 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;

[0031] 3. 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;

[0032] 4. 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;

[0033] 5. In order to further restrain the insulating rope, the insulating rope is passed through the guide hole 1 and the guide hole 2. In this way, when lifting, the insulating rope is restrained in multiple guide holes, which will be more reliable when lifting. BRIEF DESCRIPTION OF THE DRAWINGS
