Description

Insulated clamps Technical Field

[0001] This invention relates to the field of insulating tools, and in particular to an insulating clamp for safely and efficiently installing the sheds of composite insulators under energized conditions. Background Technology

[0002] Composite insulators are an indispensable key component in power systems. The design of their surface skirts is not only related to insulation performance, but also directly affects their anti-pollution and anti-icing flashover effects.

[0003] With the development of power grid technology, the performance requirements for composite insulators are increasing, especially the application of large sheds—that is, large sheds fitted over small sheds—which can significantly improve the insulation level and weather resistance of the insulators. However, the traditional shed installation method is as follows:

[0004] As shown in Figure 1, a layer of adhesive is uniformly applied to the bonding surfaces of the umbrella skirt 602, namely the first umbrella skirt bonding part 603 and the second umbrella skirt bonding part 604, with a thickness generally of 0.8mm-1mm. The adhesive is generally room temperature vulcanizing silicone rubber or ST-2 type insulating adhesive, which have good electrical and mechanical properties.

[0005] Place the shed 602 onto the composite insulator 601, ensuring a tight fit between the shed 602 and the composite insulator 601. During the bonding process, apply manual pressure to flatten any air bubbles in the cured adhesive, ensuring a gap-free bonding surface.

[0006] As can be seen from the above, traditional umbrella skirt installation usually needs to be carried out under power outage conditions, which not only affects the stable operation of the power system, but also increases operating costs and time costs.

[0007] Therefore, it is particularly important to develop a tool that can safely and efficiently install composite insulator skirts under energized conditions. Summary of the Invention

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0046] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present invention. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0047] Referring to Figures 2 and 3, an insulating clamp includes an insulating rod 30, a clamping module disposed at the top of the insulating rod 30, a handheld component 40 disposed at the bottom of the insulating rod 30, and a housing 50 movably connected to the handheld component 40. A second clamping mechanism 20 is provided with a first operating lever 208. The first operating lever 208 and the two clamping components of the second clamping mechanism 20 are connected via a second pulley group and a first connecting rope 205. The housing 50 is provided with a second operating lever 501. The second operating lever 501 and the two clamping components of the first clamping mechanism 20 are connected via a first pulley group and a third connecting rope 502. In the first clamping state, the two clamping members of the first clamping mechanism 10 are configured to clamp the first umbrella skirt adhesive portion 603 of the umbrella skirt 602, and the two clamping members of the second clamping mechanism 20 are configured to clamp the second umbrella skirt adhesive portion 604 of the umbrella skirt 602; in the second clamping state, the two clamping members of the first clamping mechanism 10 are configured to clamp the first umbrella skirt adhesive portion 603 and the second umbrella skirt adhesive portion 604 of the umbrella skirt 602, and the two clamping members of the second clamping mechanism 20 are configured to clamp the umbrella skirt 602.

[0048] It should be noted that "movable connection" means that the outer wall of the handheld part 40 is provided with multiple threads, and the inner wall of the housing 50 is provided with multiple threads. When the handheld part 40 and the housing 50 need to be fixed relative to each other, the housing 50 is screwed into the handheld part 40, and the housing 50 is fixed by the friction and preload of the threads, so that sufficient clamping force is generated between the handheld part 40 and the housing 50, thereby achieving relative fixation. When the handheld part 40 and the housing 50 need to move relative to each other, the housing 50 is loosened, allowing the housing 50 to move relative to each other in the axial direction.

[0049] The first clamping mechanism 10 includes a first main body, a first clamping member 101 disposed on one side of the first main body and away from the top of the insulating rod 30, and a second clamping member 102 disposed on the same side of the first main body and close to the top of the insulating rod 30. The first pulley group includes a first fixed pulley 103 fixedly connected to the first clamping member 101 and disposed within the first main body, a first movable pulley 104 fixedly connected to the second clamping member 102 and disposed within the first main body, and a second fixed pulley 105 disposed within the first main body. One end of the third connecting rope 502 is fixed to the second operating lever 501, and the other end passes sequentially around the second fixed pulley 105, the first fixed pulley 103, and the first movable pulley 104 and is fixed to the first fixed pulley 103.

[0050] Furthermore, the centers of the first fixed pulley 103 and the second fixed pulley 105 are on the same horizontal line. For example, if the second fixed pulley 105 is pulled to the right by a force, and the third connecting rope 502 passes around the second fixed pulley 105 and then around the first fixed pulley 103, this force will be transmitted to the first fixed pulley 103 through the third connecting rope 502, causing the first fixed pulley 103 to experience a force to the right. In this case, having the centers of the two fixed pulleys on the same horizontal line ensures that the force is transmitted smoothly in the horizontal direction, preventing additional torque or unnecessary bending of the third connecting rope 502 due to differences in the height of the fixed pulley centers. Also, the centers of the first fixed pulley 103 and the first movable pulley 104 are on the same vertical line. The third connecting rope 502, passing from the first fixed pulley 103 to the first movable pulley 104, can change the direction of the force from horizontal to vertical. The path of the third connecting rope 502 between the first fixed pulley 103 and the first movable pulley 104 is the shortest straight path. This layout reduces the bending and friction of the third connecting rope 502, thereby improving the efficiency of force transmission. The contact angle and pressure distribution of the third connecting rope 502 on the first fixed pulley 103 or the first movable pulley 104 are more uniform, reducing energy loss.

[0051] The second clamping mechanism 20 includes a second main body, a third clamping member 201 disposed on one side of the second main body and away from the top of the insulating rod 30, and a fourth clamping member 202 disposed on the same side of the second main body and close to the top of the insulating rod 30, similar to the third clamping member 201. The second pulley assembly includes a third fixed pulley 203 fixedly connected to the third clamping member 201 and disposed within the second main body, a second movable pulley 204 fixedly connected to the fourth clamping member 202 and disposed within the second main body, and a fourth fixed pulley 206 disposed within the second main body. One end of the first connecting rope 205 is fixed to the first operating lever 208, and the other end sequentially passes over the third fixed pulley 203, the second movable pulley 204, and the fourth fixed pulley 206 and is fixed to the third fixed pulley 203.

[0052] Furthermore, the centers of the third fixed pulley 203 and the fourth fixed pulley 206 are on the same horizontal line. For example, if the fourth fixed pulley 206 is pulled to the right by a force, and the first connecting rope 205 passes over the fourth fixed pulley 206 and then over the third fixed pulley 203, this force will be transmitted to the third fixed pulley 203 through the first connecting rope 205, causing the third fixed pulley 203 to experience a force to the right. In this case, having the centers of the two fixed pulleys on the same horizontal line ensures that the force is transmitted smoothly in the horizontal direction, preventing additional torque or unnecessary bending of the first connecting rope 205 due to differences in the height of the fixed pulley centers. Also, the centers of the third fixed pulley 203 and the second movable pulley 204 are on the same vertical line. The first connecting rope 205, passing from the third fixed pulley 203 to the second movable pulley 204, changes the direction of the force from horizontal to vertical. The path of the first connecting rope 205 between the third fixed pulley 203 and the second movable pulley 204 is the shortest straight path. This layout reduces the bending and friction of the first connecting rope 205, thereby improving the efficiency of force transmission. The contact angle and pressure distribution of the first connecting rope 205 on the third fixed pulley 203 or the second movable pulley 204 are more uniform, reducing energy loss.

[0053] Furthermore, pads are provided at the points where the two clamping members of the first clamping mechanism 10 contact the umbrella skirt 602, and at the points where the two clamping members of the second clamping mechanism 20 contact the umbrella skirt 602. The pads are made of silicone, which securely grips the umbrella skirt 602 while avoiding scratching it, relying on their own friction.

[0054] Both the insulating rod 30 and the housing 50 are made of epoxy fiberglass. Epoxy fiberglass is a composite of epoxy resin and glass fiber, with glass fiber acting as a reinforcing material, significantly improving the material's mechanical strength and rigidity. This material can withstand large loads and stresses, ensuring the stability and safety of the insulating rod 30 and housing 50 under high-pressure environments.

[0055] The handheld component 40 is made of rubber. Rubber is an excellent electrical insulator, effectively preventing current from being conducted to the human body through the handheld component, thus protecting the operator from electric shock. Furthermore, the rubber surface has a good coefficient of friction, providing reliable anti-slip properties even in wet or oily environments.

[0056] In other possible embodiments, as shown in FIG3, the insulating clamp further includes a reset module. The reset module is used to separate the third clamping member 201 and the fourth clamping member 202, that is, to open the third clamping member 201 and the fourth clamping member 202 from their clamping state. Specifically, the reset module includes an energy storage mechanism disposed within the second main body, a fifth fixed pulley 211 disposed within the second main body, and a pull ring 301 disposed on the insulating rod 30. One end of the energy storage mechanism is connected to the first connecting rope 205, and the pull ring 301 and the energy storage mechanism are connected via the fifth fixed pulley 211 and the second connecting rope 302.

[0057] Specifically, referring to Figure 4, the energy storage mechanism includes a counterweight 207, a latching member 209, and a second elastic element 210. One end of the counterweight 207 is connected to the first connecting rope 205, and the first operating lever 208 is fixed to the counterweight 207. One side of the latching member 209 is connected to the second connecting rope 302, and the other side engages with the counterweight 207; the latching member 209 is configured to insert into or detach from the counterweight 207. One end of the second elastic element 210 abuts against the counterweight 207, and the other end is fixed within the second main body. The latching member 209 includes a connecting rod 2091 connected to the second connecting rope 302 and horizontally disposed within the second main body, an end plate 2092 sleeved on one end of the connecting rod 2091, a stop block 2094 disposed on the other end of the connecting rod 2091, and a first elastic element 2093 whose ends respectively abut against the end plate 2092 and the stop block 2094. The end plate 2092 and the connecting rod 2091 are movably connected, with the end plate 2092 fixed inside the second main body. A U-shaped notch is provided on the side of the counterweight 207 facing the latching member 209. Both the first elastic element 2093 and the second elastic element 210 can be selected as compression springs.

[0058] Referring to Figures 5 and 6, when the first operating lever 208 presses down on the counterweight 207, the connecting rod 2091 inserts into the notch, locking the counterweight 207 and storing energy using the first elastic element 2093. Referring to Figures 3 and 7, when the pull ring 301 pulls the second connecting rope 302, the connecting rod 2091 disengages from the notch, releasing the lock on the counterweight 207. The second elastic element 210 releases the energy of elastic deformation, causing the counterweight 207 to rise.

[0059] Referring to Figures 1, 8, and 9, the working principle of this invention is as follows:

[0060] First, the operator selects a suitable umbrella skirt 602. The first umbrella skirt adhesive portion 603 of the umbrella skirt 602 is placed between the first clamping member 101 and the second clamping member 102 of the first clamping mechanism 10. The second umbrella skirt adhesive portion 604 of the umbrella skirt 602 is placed between the third clamping member 201 and the fourth clamping member 202 of the second clamping mechanism 20. The operator manually controls the first operating lever 208 to move towards the handheld part 40. The first operating lever 208 drives the counterweight 207 to move downward and compress the second elastic element 210. The movement of the counterweight 207 causes the first connecting rope 205 to drive the second movable pulley 204 to move towards the third fixed pulley 203. The fourth clamping member 202, which is connected to the second movable pulley 204, moves towards the third clamping member 201, which is connected to the third fixed pulley 203. This causes the third clamping member 201 and the fourth clamping member 202 to clamp the second umbrella skirt adhesive portion 604. Adhesive is then applied to the first umbrella skirt adhesive portion 603 of the umbrella skirt 602. The first umbrella skirt adhesive portion 603 and the second umbrella skirt adhesive portion 604 are pre-bonded near the top of the composite insulator 601 to form an adhesive portion. At this time, the first clamping mechanism 10 and the second clamping mechanism 20 are in the first clamping state. After bonding, the first clamping mechanism 10 clamps the adhesive portion, and the second clamping mechanism 20 clamps the umbrella skirt 602. At this time, the first clamping mechanism 10 and the second clamping mechanism 20 are in the second clamping state.

[0061] Secondly, the operator, wearing insulating protective equipment (such as insulating gloves and insulating shoes), uses the insulating rod 30 to slip the pre-adhesive shed 602 onto the composite insulator 601 while the power pole 60 is energized. The clamping module holds the shed 602 and precisely adjusts its position, accurately placing the shed 602 in the predetermined position on the composite insulator 601.

[0062] Then, the operator holds the handheld component 40 with one hand and controls the second operating lever 501 to move up and down with the other hand. The up and down movement of the second operating lever 501 causes the housing 50 to move. The third connecting rope 502, which is fixedly connected to the housing 50, drives the first movable pulley 104 of the first clamping mechanism 10 to move up and down in the direction of the first fixed pulley 103. The second clamping component 102, which is connected to the first movable pulley 104, moves up and down in the direction of the first clamping component 101, which is connected to the first fixed pulley 103. This causes the second clamping component 102 and the first clamping component 101 to reciprocate to clamp the first umbrella skirt adhesive part 603 and the second umbrella skirt adhesive part 604, ensuring that the umbrella skirt 602 is firmly installed on the composite insulator 601.

[0063] Finally, after installation, the second operating lever 501 is returned to its initial position, the first clamping member 101 and the second clamping member 102 are separated, the operator holds the hand-held member 40, and pulls the pull ring 301 with the other hand. The pull ring 301 drives the second connecting rope 302 to control the buckle 209 to release the previously stored energy through the fifth fixed pulley 211. The second elastic element 210 releases energy to drive the counterweight 207 to move in the opposite direction of the second elastic element 210. The first connecting rope 205 connected to the counterweight 207 drives the second movable pulley 204 to move in the opposite direction of the third fixed pulley 203. Then the fourth clamping member 202 moves in the opposite direction of the third clamping member 201, so that the second clamping mechanism 20 is opened, and the operator removes the insulated clamps.

[0064] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
