Description
Technical Field
[0001] This invention relates to the field of insulator installation, and more particularly to an insulator installation device. Background Technology
[0002] An insulator is a special type of insulating component. It is typically used by combining two or more insulator elements together in an insulator string, playing a crucial role in overhead transmission lines. The insulator body is made of ceramic or glass, and is susceptible to cracking or explosion, requiring immediate replacement.
[0003] In some areas along elevated outdoor power transmission lines, environmental constraints make it inconvenient to carry automated or semi-automated auxiliary installation equipment, and commonly used equipment and insulators often require manual transport. Therefore, manual hoisting is a common practice when replacing and installing insulators. If the rope slips during hoisting, it can damage the insulator and pose personal safety risks. While fall arrest devices are widely used, conventional fall arrest mechanisms still present safety hazards if the rope binding is faulty, as the object will experience a fall. Summary of the Invention
[0004] This invention addresses the shortcomings of existing technologies by providing an insulator installation device for replacing new insulators. It offers a stable and convenient solution by using a first rope to drive a second rope. After the new insulator is lifted, the first rope is released, preventing the new insulator from falling and avoiding the risk of it dropping. Furthermore, once the new insulator is at the top, it remains stable without requiring continuous force.
[0005] To solve the above-mentioned technical problems, the present invention provides a solution to the safety hazard of rope slippage during manual hoisting of insulators for replacement.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

Therefore, the above terms should not be construed as limitations on this invention.
[0036] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example
[0037] Please see Figure 1-9 This invention provides an insulator installation device, including a support member 1 and a connector 2. The support member 1 is fixed to the insulator, and the connector 2 is connected to two support members 1 and used to bring the two support members 1 closer together. It also includes a conveying assembly 3. The bottom of the support member 1 is provided with a hook 11. The conveying assembly 3 is connected to the support member 1 through the hook 11 and is used to send the insulator into the air. The conveying assembly 3 includes a hook ring 4, a first pulley 5, a second pulley 6, and a transmission member 7. The first pulley 5 and the second pulley 6 are installed on both sides of the transmission member 7. The hook ring 4 is fixed to the surface of the transmission member 7 and is used to connect with the hook 11. The transmission member 7 can only transmit kinetic energy in one direction. The first pulley 5 is connected to the second pulley 6 through the transmission member 7 and its rotation is controlled in one direction. A first rope for applying external force is installed on the first pulley 5, and a second rope for hoisting the insulator is installed on the second pulley 6.
[0038] In the embodiments of this application, the support member 1 is composed of an upper fixed seat 12 and a lower fixed seat 13. One end of the upper fixed seat 12 is rotatably connected to the lower fixed seat 13, and the other end is fixed by a locking member. The support member 1 is fixed on the insulator, and the two support members 1 span at least one insulator that needs to be replaced. The two support members 1 are connected by a connector 2. The connector 2 is used to manually hydraulically pull the distance between the two support members 1 closer, so that the insulator in the middle is in a loose state, which facilitates replacement.
[0039] In the embodiments of this application, the bottom of the support member 1 is integrally formed or welded with a hook 11, and the conveying assembly 3 is connected through the hook 11. The conveying assembly 3 is used to transport new insulators from the ground to a higher position and to send insulators that have been replaced at a higher position to the bottom surface. The conveying assembly 3 is installed on the support member 1, and the hook 11 is on the support member 1, which serves as a mobile suspension point, allowing the insulators to be in a position that is easy for workers to reach, making the replacement of insulators more convenient.
[0040] It should be noted that the conveying assembly 3 consists of a hook 4, a first pulley 5, a second pulley 6, and a transmission component 7. The hook 4 is located at the top of the transmission component 7 and is used to connect with the hook 11. The first pulley 5 and the second pulley 6 are respectively movably installed on both sides of the transmission component 7. A first rope, either mechanically or manually pulled, is fitted onto the first pulley 5, and a second rope, which is suspended and insulated, is fitted onto the second pulley 6. Both the first and second ropes are loop structures connected end to end. When the first rope is pulled, the first pulley 5 will rotate, and the kinetic energy will be transmitted to the second pulley 6 through the transmission component 7.
[0041] When the first pulley 5 is stationary, the transmission component 7 will self-lock, preventing the second pulley 6 from rotating; thus, when the external force is removed, the insulator can be prevented from falling.
[0042] In some implementations, the first pulley 5 may be designed as a movable pulley system, which can reduce the pressure during insulator transport.
[0043] In the embodiments of this application, the surfaces of the first pulley 5 and the second pulley 6 are both provided with a first protrusion 51 protruding circumferentially. The end of the first protrusion 51 is sharp and can be inserted into the first rope and the second rope, so that the first pulley 5 and the second pulley 6 can rotate synchronously with the first rope and the second rope, respectively.
[0044] In the embodiments of this application, the transmission component 7 includes a cover 71, a first rotating shaft 72, and two second rotating shafts 73, etc. The first rotating shaft 72 and the two second rotating shafts 73 are arranged in parallel. One end of the first rotating shaft 72 passes through the cover 71 and is used to install the second pulley 6 to achieve synchronous rotation. One end of the second rotating shaft 73 passes through the cover 71 and is used to install the first pulley 5 to achieve synchronous rotation.
[0045] The two second rotating shafts are engaged by 73-tooth transmission and rotate synchronously in opposite directions.
[0046] A first gear 721 is fitted onto a first rotating shaft 72, and the first rotating shaft 72 engages with one of the second rotating shafts 73 via the first gear 721. The first gear 721 exhibits a rotational delay when switching between forward and reverse rotation. Specifically, the first gear 721 consists of a bushing 7211 and a gear ring 7212. The bushing 7211 is fitted onto the first rotating shaft 72, and the gear ring 7212 is fitted onto the bushing 7211. The inner end of the bushing 7211 has a groove 7213, within which a stop 7214 is provided. The inner ring of the bushing 7211 has a second protrusion 7215 that penetrates the groove 7213 and meshes with the stop 7214. This results in a rotational delay approaching 360° each time.
[0047] It should be noted that a toothed plate 74 is longitudinally provided on one side of the second rotating shaft 73, which can engage with it in gear transmission. The toothed plate 74 is mounted on the base 78 of the drive slide groove 77. The bottom of the toothed plate 74 passes through the slide groove 77 and engages with it in sliding cooperation. Elastic elements 79 are installed at both ends of the toothed plate 74. The elastic elements 79 can engage with the second rotating shaft 73 in gear transmission. When the toothed plate 74 moves, it will mesh with the second rotating shaft 73 in transmission. After the toothed plate 74 moves to one end of the slide groove 77, it will stop moving. At this time, the elastic elements 79 will always be engaged with the second rotating shaft 73 in transmission.
[0048] Among them, the elastic element 79 is composed of a rack and a spring. The rack is parallel to the end of the toothed plate 74 and connected to it through the spring. The second rotating shaft 73 can cooperate with the rack for transmission.
[0049] It should be noted that two ratchet components 75 are symmetrically sleeved on the first rotating shaft 72, and the ratchet components 75 are connected to the toothed plate 74 via a guide rod 76. Each ratchet component 75 consists of a ratchet 751 and a pawl 752. The ratchet 751 is sleeved on the first rotating shaft 72, and one end of the pawl 752 is connected to the guide rod 76, while the other end engages with the ratchet 751. The pawl 752 is supported from the middle, and the toothed plate 74 moves during its movement, causing the guide rod 76 to move. When the toothed plate 74 is located at both ends of the sliding groove 77, the ratchet 751 and the pawl 752 are in engaged and disengaged states, respectively.
[0050] In the specific implementation process, when the first pulley 5 is rotated by pulling the first rope to lift the insulator, the first pulley 5 drives the two second rotating shafts 73 to rotate synchronously, causing the toothed plate 74 to move to one end of the slide groove 77. At this time, the ratchet 751 and the pawl 752 are engaged but not meshed. Due to the delay of the first gear 721, the first rotating shaft 72 will only rotate when the second rotating shaft 73 continues to rotate, and control the movement of the second rope.
[0051] When the external force is removed, the second shaft 73 stops rotating. Due to the gravity of the insulator, the second rope falls in the opposite direction. The ratchet 751 and pawl 752 engage in opposite directions, and the pawl 752 locks the second shaft 73, preventing the second rope and insulator from falling.
[0052] When the first rope is pulled in the opposite direction, the first pulley 5 rotates the lower insulator in the opposite direction. The first pulley 5 drives the two second rotating shafts 73 to rotate synchronously, so that the toothed plate 74 moves to the other end of the slide groove 77. At this time, the ratchet 751 and the pawl 752 separate. Due to the delay of the first gear 721, the first rotating shaft 72 will only rotate when the second rotating shaft 73 continues to rotate, and control the movement of the second rope.
[0053] This invention is primarily used for fall protection of new insulators. After the new insulator is hoisted, once the first rope is released, the new insulator will not tend to fall, thus avoiding the risk of the insulator falling. Furthermore, once the new insulator is hoisted to the top, it remains stable without requiring continuous force.
[0054] It should be noted that this application includes two sets of toothed plates 74 and ratchet components 75, which can improve fall protection stability.
[0055] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
