Description

Technical Field

[0001] This application relates to the field of insulator technology, and more particularly to an insulator replacement device. Background Technology

[0002] When installing power lines, insulator strings are used as a connecting structure to suspend the lines from power towers, thereby improving the safety of the lines when energized. However, since power towers are mostly installed outdoors, the insulators are easily damaged due to long-term exposure to the natural environment. Therefore, workers need to regularly maintain and replace the insulator strings. An insulator string consists of several insulators and connecting blocks between adjacent insulators; in other words, the entire insulator string has a certain weight.

[0003] However, the current method of replacing insulator strings mainly relies on using ropes to tie the insulator strings to be replaced, and then using the ropes to control the removal of the insulator strings to slowly lower them until they are placed on the ground. Similarly, the new insulator strings are tied to the ropes, and then the ropes are used to pull the insulator strings up to the power tower. The entire replacement process relies entirely on manual operation by the workers on the power tower. When replacing multiple sets of insulator strings, the above process must be repeated continuously, which increases the intensity of manual labor, easily causes muscle fatigue of the workers on the power tower, consumes manpower, and reduces the efficiency of replacing insulator strings.

The ends of the two first connecting plates away from the insulators pass through the corresponding mounting plate bodies and are mounted on the power tower by connecting ropes. Each first connecting plate is detachably connected to its corresponding mounting plate body. The hand chain hoist body has two ends connected to two mounting plate bodies respectively, which are used to drive the two mounting plate bodies to slide along the length direction of the support frame body to achieve tensioning or slack of the insulator.

[0006] Optionally, the support frame body includes two first support rods and two second support rods; Two first support rods are arranged parallel to each other, one of the second support rods is perpendicularly connected to one end of the two first support rods, and the other second support rod is perpendicularly connected to the other end of the two first support rods; Both mounting plate bodies are slidably connected to the two first support rods and can slide back and forth along the length of the first support rods.

[0007] Optionally, two trays are provided at intervals on the two first support rods; Each of the trays is connected to two of the first support rods at both ends and has its opening facing upwards. The inner surfaces of the two trays are in contact with the insulator to support the insulator.

[0008] Optionally, each of the mounting plate bodies includes two mounting plates that are detachably connected together, one above the other; Each of the first connecting plates and each of the hand chain hoists is sandwiched between the two mounting plates of the corresponding mounting plate body and is detachably connected to the two mounting plates.

[0012] The insulator replacement device provided in this application slides two mounting plate bodies on the support frame body, and sets first connecting plates at both ends of the insulator along its length direction.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] refer to Figures 1 to 4 This application provides an insulator replacement device, comprising: The support frame body 100 serves to support the entire insulator replacement device.

[0018] Two mounting plate bodies 200 are slidably mounted on the support frame body 100, with an insulator 300 disposed between them. Each end of the insulator 300 along its length is provided with a first connecting plate 400. The ends of the two first connecting plates 400 away from the insulator 300 pass through their corresponding mounting plate bodies 200 and are mounted on the power tower 501 via connecting ropes 500. Each first connecting plate 400 is detachably connected to its corresponding mounting plate body 200. The number of insulators 300 installed on the power tower 501 is usually determined according to the voltage level, with different voltage levels corresponding to different numbers of insulators 300. This application does not impose a specific limitation on this number. The connecting rope 500 can be a steel wire rope, used to install the insulator 300 with the first connecting plate 400 on the power tower 501. The first connecting plate 400 and the mounting plate body 200 can be detachably connected by the first fastening bolt and the first nut. Specifically, the first connecting plate 400 and the mounting plate body 200 are both provided with first threaded through holes. The screw end of the first fastening bolt passes through the first threaded through hole on the mounting plate body 200 and the first threaded through hole on the first connecting plate 400 in sequence, and the first nut is selected on the first fastening bolt so that the first nut abuts against the lower surface of the mounting plate body 200, thereby realizing the detachable connection between the first connecting plate 400 and the mounting plate body 200, thus improving the convenience of replacing the insulator 300.

[0019] The manual chain hoist body 600 has two ends connected to two mounting plate bodies 200, which are used to drive the two mounting plate bodies 200 to slide along the length of the support frame body 100 to tension or loosen the insulator 300. The manual chain hoist body 600 is a manual chain hoist, also known as a chain hoist, chain hoist, or manual hoist. It is a simple and portable manual lifting machine, also called a "ring chain hoist" or "chain hoist." In other words, the manual chain hoist body 600 is existing technology and not an innovation of this application. The working principle of the manual chain hoist body 600 can be found in existing technology. Since the entire insulator string 300 has a certain weight, this application uses the manual chain hoist body 600 to drive the mounting plate bodies 200 to slide along the length of the support frame body 100 to tension and loosen the insulator 300, making the replacement of the insulator 300 easier and reducing the labor intensity of the workers.

[0020] The insulator replacement device provided in this application uses two mounting plate bodies 200 slidably mounted on a support frame body 100. First connecting plates 400 are respectively mounted at both ends of the insulator 300 along its length. The two first connecting plates 400 are detachably connected to their corresponding mounting plate bodies 200. A hand-operated hoist body 600 is mounted on the two mounting plate bodies 200, and the hoist body 600 drives the mounting plate bodies 200 to slide along the length of the support frame body 100, thereby achieving tensioning or loosening of the insulator 300 between the two mounting plate bodies 200. Specifically, when it is necessary to replace the insulator 300, the device uses... Lifting equipment (such as a crane) lifts the good insulator 300 and the insulator replacement device described in this application to the insulator 300 that needs to be replaced. It is then installed on the frame of the power tower 501 using connectors (such as connecting rods or binding ropes, not shown in the figure). One end of the first connecting plate 400 on one side of the insulator 300 installed on the power tower 501 and connected to the power tower 501 is detached. One end of the detached connecting rope 500 is then attached to the worker, ensuring that the first connecting plate 400 on that side passes through the mounting plate body 200 and is connected to it. The above operation is repeated to install the other end of the insulator 300... The first connecting plate 400 is connected to its corresponding mounting plate body 200. By operating the hand chain hoist body 600, the two mounting bracket bodies 200 slide on the support bracket body 100, and the two mounting plate bodies 200 slide on the mounting bracket body 100 to move closer to each other, thereby compressing the insulator 300. After the insulator 300 is compressed, the two first connecting plates 400 on the insulator 300 are removed from their corresponding two mounting plate bodies 200. The two first connecting plates 400 on the insulator 300 are then fixed to the mounting plate bodies 200. Finally, by operating the hand chain hoist body 600, the two mounting plate bodies 200 are... The insulators slide on the support frame body 100 and move away from each other until the good insulator 300 is in a taut state. At this time, the two first connecting plates 400 on the good insulator 300 are connected to one end of the connecting rope 500 hanging on the worker. After the insulator 300 and the end of the connecting rope 500 away from the power tower 501 are connected, the first connecting plates 400 on the insulator 300 are removed from the mounting plate body 200. The end of the entire insulator replacement device connected to the mounting plate body 200 through the connector is disconnected. The insulator replacement device and the removed insulator 300 are hoisted to the ground, thus realizing the installation of the insulator 300.In the process of replacing insulator 300 using the insulator replacement device, the device supports both the insulator 300 to be replaced and the good insulator 300, thus avoiding the need for manual lifting of the insulator 300 during the replacement process. This saves manpower and improves the stability and efficiency of the insulator 300 replacement process.

[0021] It should be noted that the insulator replacement device in this application is applicable not only to the installation of horizontal insulators 300 shown in the figure, but also to the installation of vertical insulators 300 and the like.

[0022] In some embodiments, reference Figure 1 and Figure 2 The support frame body 100 in this application includes two first support rods 101 and two second support rods 102. Specifically, the two first support rods 101 are arranged parallel to each other, one of the second support rods 102 is perpendicularly connected to one end of the two first support rods 101, and the other second support rod 102 is perpendicularly connected to the other end of the two first support rods 101. The second support rods 102 and the first support rods 101 are fixedly connected or detachably connected by fastening bolts or the like. The connection method between the second support rods 102 and the first support rods 101 can be set according to the actual situation, and this application does not specifically limit it.

[0023] Both mounting plate bodies 200 are slidably connected to the two first support rods 101 and can slide back and forth along the length of the first support rods 101. This allows one mounting plate body 200 to move closer to the other mounting plate body 200 to loosen the insulator 300, facilitating the replacement of the insulator 300. Conversely, one mounting plate body 200 can move away from the other mounting plate body 200 to tension the insulator 300, thus completing the installation of the replaced insulator 300.

[0024] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 In this application, two first support rods 101 are provided with two trays 1011 at intervals; wherein, each tray 1011 is connected to the two first support rods 101 at both ends and the opening faces upward, and the inner surface of the two trays 1011 contacts the insulator 300 to support the insulator 300.

[0025] In the above embodiments, since the insulator 300 has a certain weight, the two support plates 1011 support the insulator 300, which can ensure the stability of the insulator 300 during replacement and use, thereby ensuring the stability of the insulator 300 during operation.

[0026] In some embodiments, reference Figure 1 and Figure 2 Each mounting plate body 200 in this application includes two mounting plates 201 that are detachably connected together. The two mounting plates 201 can be detachably connected together by a second fastening bolt and a second nut. Specifically, the two mounting plates 201 are provided with second threaded through holes, and the second fastening bolt passes through the second threaded through holes of the two mounting plates 201 in sequence. The second nut is screwed on the second fastening bolt and contacts the lower surface of the mounting plate 201 located below, thereby realizing the detachable connection of the two mounting plates 201 and making the installation and removal process of the two mounting plates 201 more convenient.

[0027] In addition, each first connecting plate 400 and each chain hoist body 600 are sandwiched between two mounting plates 201 of their corresponding mounting plate body 200 and are detachably connected to the two mounting plates 201. This facilitates the disassembly and installation of the first connecting plate 400 and the chain hoist body 600 with the mounting plates 201, and improves the convenience of the installation and disassembly process of the first connecting plate 400 and the chain hoist body 600.

[0028] In each mounting plate body 200, the lower surface of the mounting plate 201 located at the bottom is provided with two slip rings 2011. The slip rings 2011 correspond one-to-one with the two first support rods 101 and are respectively sleeved on the corresponding first support rods 101 and can slide back and forth along the length direction of the first support rods 101.

[0029] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 In this application, the two first connecting plates 400 are fixedly connected to both ends of the insulator 300. The end of each first connecting plate 400 away from the insulator 300 passes through the two mounting plates 201 in each corresponding mounting plate body 200 and is provided with a hanging ring 401. The hanging ring 401 is used to connect the connecting rope 500.

[0030] In the above embodiment, the hanging ring 401 and one end of the first connecting plate 400 can be detachably connected together by bolts or the like. One end of the connecting rope 500 passes through the hanging ring 401 and is tied together with the hanging ring 401, while the other end of the connecting rope 500 is connected to the power tower 501. This enables the insulator 300 to be installed on the power tower 501. The connection between the hanging ring 401 on the first connecting plate 400 of the insulator 300 and the power tower 501 is achieved through the connecting rope 500, making the replacement and installation of the insulator 300 more convenient and easier to operate.

[0031] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 In this application, a second connecting plate 700 is sandwiched between the two mounting plates 201 in the two mounting plate bodies 200. Each second connecting plate 700 is detachably connected to the two mounting plates 201 in its corresponding mounting plate body 200. Specifically, the second connecting plate 700 can be fixed together by a third fastener and a third nut. Both the second connecting plate 700 and the mounting plate body 200 have a third threaded through hole. The threaded end of the third fastening bolt passes through the third threaded through hole in the mounting plate body 200 and the third threaded through hole in the second connecting plate 700 in sequence, and the third nut is selected on the third fastening bolt so that the third nut abuts against the lower surface of the mounting plate body 200. This achieves a detachable connection between the second connecting plate 700 and the mounting plate body 200, thereby improving the convenience of installing or removing the second connecting plate 700.

[0032] The hand chain hoist body 600 has two ends that are respectively hooked to two second connecting plates 700. The chain of the hand chain hoist body 600 is parallel to the length direction of the first support rod 101. Specifically, the hand chain hoist body 600 is equipped with hooks, and the second connecting plates 700 have hanging holes. The hand chain hoist body 600 is hooked to the second connecting plates 700 by hooking into the hanging holes, thereby improving the convenience of installing and disassembling the hand chain hoist body 600.

[0033] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 The hand chain hoist body 600 of this application is provided with a rocker arm 601 that can extend or shorten the chain of the hand chain hoist body 600.

[0034] In the above embodiments, since the hand chain hoist body 600 is existing technology, a rocker arm 601 is provided on the hand chain hoist body 600. The rotation of the rocker arm 601 causes the chain of the hand chain hoist body 600 to lengthen or shorten, thereby increasing or decreasing the distance between the two mounting plate bodies 200. Ultimately, this achieves the tensioning or loosening of the insulator 300, which facilitates the replacement of the insulator 300 and improves the replacement efficiency of the insulator 300.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
