Description

Technical Field

[0001] This invention relates to the field of insulator replacement hanger technology, and more particularly to a ladder-type hanger for replacing insulators in transmission lines. Background Technology

[0002] Currently, composite insulators are widely used in heavily polluted areas of power transmission lines. When these composite insulators show signs of aging or overheating, they need to be replaced. Because the sheaths of composite insulators are made of silicone and cannot be stepped on, workers must use a rope ladder to access the conductor from the crossarm. They then assemble the clamps, pull plates, and conductor hooks before replacing the insulator. Since the lower end of the rope ladder cannot be secured, climbing up and down it is difficult and physically demanding. The entire operation requires a variety of tools and equipment, making field transport challenging. Summary of the Invention

[0032] Example 1

[0033] Reference Figure 1 The first embodiment of the present invention provides a climbing-type boom for replacing insulators of transmission lines. This device includes a climbing assembly 100, which includes a first rod body 101 and a first support member 102 disposed on the first rod body 101; and a fixing assembly 200, which includes a second rod body 201, a transmission member 202 disposed on the second rod body 201, and a first fixing member 203 and a second fixing member 204 respectively connected to the two ends of the second rod body 201 by threads; the fixing assembly 200 is fixedly connected to the first rod body 101 through the second rod body 201.

[0034] Furthermore, the operating component 300 is connected to the transmission component 202 of the fixing component 200, and can drive the second rod 201 to rotate by driving the transmission component 202 through the operating component 300, so that the first fixing component 203 and the second fixing component 204 can move relative to the second rod 201 respectively.

[0035] Based on this, the first support member 102 on this ladder-type boom is symmetrically arranged along the outer side wall of the first boom body 101, and the interval between multiple first support members 102 is 40cm to 60cm, so that workers can step on the first support member 102 to climb. The ladder-type boom is fixed by the fixing component 200.

[0036] In this embodiment, both the first fixing member 203 and the second fixing member 204 include a hook body J-1 and a screw J-2 fixed to one end of the hook body J-1. The hook body J-1 is located at both ends of the fixing member and is provided with a snap fastener. The hook body is provided with a protrusion that cooperates with the snap fastener, so that the fixing ring formed by the combination of the hook body J-1 and the snap fastener can only enter the fixing ring through the fixable material outside the center (such as the iron frame on one side of the insulator). After entering, the snap fastener is springed up by the elastic force and is also acted on by the protrusion that cooperates with the snap fastener to lock the fixing ring and prevent the fixable material from sliding out of the inside of the fixing ring.

[0037] In this embodiment, the operating component 300 includes a connector 301 sleeved around the transmission component 202, a drive block 302 disposed inside the connector 301, and an operating rod 303 connected to the outer end of the connector 301. The drive block 302 is in contact with the transmission component 202 and can drive the transmission component 202 to rotate under the rotation of the connector 301. When a clockwise (counterclockwise) thrust is applied to the operating rod 303, the drive block 302 and the operating rod 303 move synchronously and drive the transmission component 202 to rotate. The clockwise (counterclockwise) rotation of the transmission component 202 drives the screw J-2 connected to the rotating component to move away from (towards) the transmission component 202.

[0038] By changing the vertical height of the screws J-2 at both ends of the fixing component, the vertical height of the hooks J-1 connected to the screws J-2 is changed, thus enabling the ladder-type boom to adapt to iron frames and other fixing points at different vertical distances. The overall fixing of the ladder-type boom is achieved by clamping the two fixing points with the hooks J-1 at both ends of the fixing component.

[0039] The following is a detailed description of the structure of "transmission component 202 and drive block 302":

[0040] Specifically, the transmission component 202 is a gear fixed on the second rod 201; the drive block 302 includes a first pressure rod 302a and a second pressure rod 302b, one end of the first pressure rod 302a and the second pressure rod 302b are fixedly connected to each other and form a bend Z, and the other end extends outward and can contact the transmission component 202.

[0041] The drive block 302 is rotatably fixed to the connector 301 at its bend Z. When the first pressure rod 302a or the second pressure rod 302b of the drive block 302 abuts against the transmission member 202, the transmission member 202 can be driven to rotate by the rotation of the connector 301.

[0042] In this embodiment, the bend angle Z between the first pressure rod 302a and the second pressure rod 302b is matched with its rod length. When the first pressure rod 302a and the second pressure rod 302b abut against the transmission member 202, there is a certain distance between the two rods to achieve a good abutment effect between the first pressure rod 302a and the second pressure rod 302b.

[0043] Specifically, the drive block 302 also includes a toggle lever 302c; one end of the toggle lever 302c is fixed at the angle Z and extends outward in the direction of the angle bisector of the angle Z; the angle between the toggle lever 302c and the first pressure lever 302a is greater than 90°, and the angle between the toggle lever 302c and the second pressure lever 302b is greater than 90°.

[0044] The straight section between the angle Z and the transmission component 202 is the first section Q; the operating component 300 also includes a tension member 304 disposed inside the connector 301, one end of the tension member 304 is fixed to the end of the lever 302c, and the other end is fixed to the first section Q; the side of the connector 301 is provided with a window 301a communicating with the lever 302c.

[0045] Based on this, the first pressure rod 302a and the second pressure rod 302b on this operating component 300 are arranged left and right in the longitudinal direction (that is, in the longitudinal direction, the first pressure rod 302a and the second pressure rod 302b are distributed left and right along the first section Q). The position of the first pressure rod 302a and the second pressure rod 302b can be changed by setting the toggle rod 302c in the direction of the first section Q.

[0046] In this embodiment, the connector 301 can be adjusted from the outside by setting window 301a. By setting tension member 304 inside connector 301 and fixing the other end to the end of lever 302c, the first pressure rod 302a and the second pressure rod 302b only exist in the state of contacting the transmission member 202, and there is no intermediate state.

[0047] The tension member 304 is connected to the end of the actuating rod 302c. The tension on the actuating rod 302c and the tension member 304 is as follows: when the direction of the actuating rod 302c is equal to the direction of the first section Q, the tension on the actuating rod 302c by the tension member 304 is at its maximum value. Therefore, the actuating rod 302c moves in the direction of decreasing tension of the tension member 304. By adjusting the actuating rod 302c, the first pressure rod 302a abuts against the protrusion on the transmission member 202 (gear) {the second pressure rod 302b abuts against the protrusion on the transmission member 202 (gear)}, so as to limit the transmission member 202 and prevent the transmission member 202 from retracting, thereby preventing the hooks J-1 at both ends from retracting, so as to achieve a better fixing effect.

[0048] Example 2

[0049] Reference Figure 1This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the operating component 300 of this device further includes a first slider 305, a second slider 306, and an elastic member 310 connected between the two.

[0050] The connector 301 has a first slide groove 301b inside, and the length direction of the first slide groove 301b is perpendicular to the direction of the first segment Q; the first slider 305 and the second slider 306 are respectively slidably connected to the first slide groove 301b.

[0051] Among them, the elastic element 310 enables the first slider 305 and the second slider 306 to abut against the groove wall of the first slide groove 301b when no external force is applied. The first slide groove 301b provides a sliding position for the slider and cooperates with the slider to fix the slider perpendicular to the slide groove direction and move only along the horizontal direction of the slide groove.

[0052] In this embodiment, the operating component 300 further includes a traction cable 307, a guide plate 308 fixed on the operating rod 303, and an operating roller 309 disposed on the guide plate 308. One end of the traction cable 307 is fixed to the first slider 305, the other end is fixed to the second slider 306, and passes around the operating roller 309, so that the traction cable 307 is divided into a first traction segment 307a and a second traction segment 307b by the operating roller 309.

[0053] In this embodiment, the slider is pulled by the traction cable 307, so that the slider is subjected to a longitudinal force perpendicular to the first groove 301b and a lateral force moving from the slider to the first section Q, thereby changing the horizontal position of the slider to realize the force transmission of the slider to the actuating rod 302c, so as to change the position of the first pressure rod 302a and the second pressure rod 302b.

[0054] The operating roller 309 includes a first mating area 309a and a second mating area 309b; the traction cable 307 is connected to the first mating area 309a, and the traction cable 307 is provided with a first toothed area 307c corresponding to the first mating area 309a, and the periphery of the first mating area 309a is provided with teeth that mate with the first toothed area 307c; the operating lever 303 is provided with a second toothed area 303a corresponding to the second mating area 309b, and the periphery of the second mating area 309b is provided with teeth that mate with the second toothed area 303a.

[0055] It should be noted that the first mating area 309a and the traction cable 307 are mated. When the teeth on the first mating area 309a and the first tooth area 307c on the traction cable 307 are locked and moved, the traction cable 307 can be driven to move, so that the traction cable 307 can be moved relative to the roller 309.

[0056] Therefore, the guide plate 308 is provided with a second groove 308a that allows the operating roller 309 to slide. At the same time, the outer side of the operating roller 309 is provided with a protrusion 309c that slides in contact with the second groove 308a. The protrusion 309c provides an operating position for operating the operating roller 309 from outside the guide plate 308. By moving the protrusion 309c, the operating roller 309 is slid, thereby driving the movement of the traction cable 307. In addition, the traction cable 307 passes through the side of the operating lever 303 near the guide plate 308, so that the traction cable 307 contacts the operating roller 309.

[0057] In this embodiment, the connector 301 is provided with a first guide roller 301c and a second guide roller 301d. The first guide roller 301c has a pair corresponding to the first traction section 307a and the second traction section 307b respectively, and is respectively located on the side of the first traction section 307a and the second traction section 307b away from the first section Q.

[0058] By setting the first guide roller 301c, which is positioned on the side of each traction section away from the first section Q, this position provides a force point supported by itself (the first guide roller 301c) when the traction cable 307 is subjected to the tension transmitted from the operating roller 309, so that the traction cable 307 can bring a better tension effect to apply tension to the slider.

[0059] By setting a second guide roller 301d, which is positioned on the side of each traction section close to the guide plate 308, this position provides a force point supported by itself (the second guide roller 301d) when the traction cable 307 is subjected to the tension transmitted from the operating roller 309, so that the traction cable 307 can bring a better tension effect to apply tension to the slider.

[0060] Correspondingly, the operating lever 303 has a channel T inside, and a through hole is provided on the operating lever 303 at a position corresponding to the guide plate 308; the first traction section 307a and the second traction section 307b pass through the channel T and exit through the through hole.

[0061] To cooperate with the first support member 102, the second rod body 201 is provided with a second support member 205, which makes it easier for workers to step on it. The first rod body 101 also includes a first telescopic rod 101a and a second telescopic rod 101b that are connected to each other. When not in use, the first rod body 101 can retract its length for easy storage.

[0062] In this embodiment, the slider, traction cable, operating roller, and their cooperating parts achieve good operation of the fixed component. The specific implementation process is as follows:

[0063] By moving the operating roller 309 from the outside, it slides along the second groove 308a. During the sliding process, the first mating area 309a of the operating roller 309 and the traction cable 307 are engaged by the teeth. When the operating roller 309 slides, the traction cable 307 will also slide relative to it.

[0064] To match this, a second mating area 309b of the operating roller 309 is designed. When the protrusion 309c on the outer side of the operating roller 309 is contacted, the protrusion 309c can be configured to rotate in contact with the operating roller 309, so that the teeth on the second mating area 309b interact with the second tooth area 303a on the operating rod 303, thereby achieving the rotation of the operating roller 309. This causes the first traction section 307a and the second traction section 307b to be subjected to different tensile forces, so that the first slider 305 and the second slider 306 connected to different traction sections undergo different displacements.

[0065] The specific working process is described as follows: When the operating roller 309 moves relative to the fixed component 200 along the second slide groove 308a, the operating roller 309 rotates clockwise due to the interaction between the convex teeth on the second mating area 309b and the second convex tooth area 303a on the operating rod 303 (with the guide plate 308 located to the right of the operating rod 303 as the top view). At this time, the tension on the first traction section 307a is greater than the pressure on the second traction section 307b. At this time, the first slider 305 contacts the actuating rod 302c faster than the second slider 306. The actuating rod 302c is pushed by the first slider 305. At this time, the actuating rod 302c moves to the left and crosses the straight line where the first section Q is located, thereby causing the second pressure rod 302b to push the transmission component 202 (gear).

[0066] When the operating roller 309 moves away from the fixed component 200 along the second slide groove 308a, the operating roller 309 rotates counterclockwise due to the interaction between the convex teeth on the second mating area 309b and the second convex tooth area 303a on the operating lever 303 (with the guide plate 308 located to the right of the operating lever 303 as the top view). At this time, the tension on the first traction section 307a is less than the pressure on the second traction section 307b. At this time, the second slider 306 contacts the actuating lever 302c faster than the first slider 305. The actuating lever 302c is pushed by the second slider 306. At this time, the actuating lever 302c moves to the right and crosses the straight line where the first section Q is located, thereby causing the first pressure rod 302a to push the transmission component 202 (gear).

[0067] After the entire movement process is completed, since the first pressure rod 302a (second pressure rod 302b) is in the pushing state of the transmission component 202 (gear), the traction cable 307 will not be subjected to the thrust from the transmission component 202 (gear). That is, the operating roller 309 does not need to be limited after achieving its own benefit. When it is necessary to change the pushing state of the pressure rod on the transmission component 202 (gear), that is, to change the direction of rotation of the transmission component 202 (gear) under force, that is, to change the movement state of the hooks J-1 at both ends of the fixing component towards the operating component 300 (away from the distance operating component 300), the operating roller 309 is operated.

[0068] After the adjustment component is completed, when a clockwise (counterclockwise) thrust is applied to the operating lever 303, the drive block 302 and the operating lever 303 move synchronously and drive the transmission component 202 to rotate. The clockwise (counterclockwise) rotation of the transmission component 202 drives the screw J-2 connected to the rotating component to move away from (towards) the transmission component 202.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
