Description

Technical Field

[0001] The present invention relates to the technical field of insulator replacement tools, and in particular to an insulator non-stop replacement device and a use method thereof. Background Art

[0002] An insulator string refers to a component that combines two or more insulator elements together to flexibly suspend or support a conductor. In the construction of high-voltage lines, many lines are erected at high altitudes. High-altitude lines usually require insulators or insulator strings to fix the high-voltage lines on tension towers or straight towers. In the prior art, when replacing a single insulator, it is usually necessary to disassemble the entire insulator after a power outage and then replace it manually, which will take up a long working time and also pose certain safety hazards.

[0003] Chinese patent document CN115241793A, publication (announcement) date: 2023.09.15, discloses a method for replacing insulators of a transmission line, comprising the following steps: S1, fixing an insulator replacement device on a transmission tower; S2, unlocking the insulator string to be replaced and moving it out of its original position, then placing a new insulator string into the predetermined position of the insulator string and locking it; S3, disassembling the insulator replacement device to complete the replacement of the insulator string. Its characteristics are: this method pre-fixes the insulator replacement device on the transmission tower, so that the insulator string to be replaced is located within the working range of the replacement robot and the positioning robot. After the driving part locks the new insulator string, the insulator string replacement device can be disassembled to complete the automatic unlocking, replacement and locking operations of the insulator string, with high replacement efficiency and low operation risk; its disadvantage is: replacing the insulator string by the robot is suitable for working scenarios with longer insulator strings, and requires the cooperation of two robots.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0021] See also Figure 7 The insulator string is composed of a plurality of insulators 1, a T-shaped card plate 2 is formed at the lower end of the insulator 1, and a card slot 3 corresponding to the T-shaped card plate 2 is formed on one side of the upper end of the insulator 1, and the upper end of the card slot 3 is a closed spherical shell structure, and the cooperation between the card plate and the card slot 3 is achieved through horizontal displacement. Therefore, two adjacent insulators 1 are basically limited in the vertical direction, thereby realizing the series connection between each insulator 1, which can be understood by those skilled in the art. Each insulator 1 is serially connected in sequence along the vertical direction. Different numbers of insulators 1 are selected according to actual needs, and the height of each insulator 1 is the same. Therefore, the preset position of the vertical displacement drive device in the present application can be determined according to the required height positions of different insulators 1.

[0022] Embodiment 1: See also Figure 1-6 , an insulator non-stop replacement device, comprising a support seat 4, a horizontal slider 5, a first push rod 6, a sliding bracket 7, a vertical slider 8, a vertical displacement driving device and a lifting frame 9. The support seat 4 is installed on the transmission line tower. The support seat 4 is in a long strip shape. The upper side of the support seat 4 forms a slide groove 10 extending along the length direction of the support seat 4. The horizontal slider 5 is slidably arranged in the slide groove 10, and the horizontal slider 5 can slide along the slide groove 10. The insulator 1 at the bottom end of the insulator string is fixed on the horizontal slider 5, so the insulator 1 above can be displaced to a required position together with the horizontal slider 5.

[0023] Among them, the power for the movement of the horizontal slider 5 is realized by the first push rod 6. The first push rod 6 is installed on the support seat 4, and the output end of the first push rod 6 is connected to the horizontal slider 5. When the first push rod 6 is extended or retracted, it can drive the horizontal slider 5 to move in the horizontal direction; at the same time, the sliding bracket 7 can be displaced longitudinally along the support seat 4. This process can be achieved through manual operation or automatic control.

[0024] A vertical slider 8 is provided on the sliding bracket 7 to slide along the vertical direction. A vertical displacement driving device is installed on the sliding bracket 7. The output end of the vertical displacement driving device is connected to the vertical slider 8. The vertical slider 8 is fixedly connected to a lifting frame 9. A bayonet for lifting and engaging the insulator 1 is formed on the side of the lifting frame 9 facing the insulator string. By installing the lifting frame 9 with the bayonet, the upper side of the insulator 1 to be replaced can be conveniently inserted. The preset position of the vertical slider 8 can be determined according to the required height position of different insulators 1. The vertical displacement driving device can drive the vertical slider 8 to move up and down to achieve a small lift of the upper insulator 1 to prevent the upper insulator 1 from moving with the insulator 1 to be removed. After the movement, the insulator 1 to be removed can be manually disassembled and replaced, and then the first push rod 6 is started to move the lower insulator 1 to the original position, realizing the replacement operation without power outage.

[0025] In this embodiment, see Figure 3 The lifting frame 9 includes a bottom plate 11 and two side limit rods 12 fixed at both ends of the bottom plate 11. The two side limit rods 12 cooperate with the bottom plate 11 to form the bayonet. The width between the two side limit rods 12 is smaller than the maximum diameter of the insulator 1. Therefore, when the lifting frame 9 is lifted upward, the insulator 1 to be lifted can be driven to move upward together. The side limit rods 12 of the present invention are made of insulating material, which can increase the safety during lifting.

[0026] In this embodiment, see Figure 3 , 4, the outer end of the side limit rod 12 is rotatably matched with the vertical shaft 13, the upper end of the vertical shaft 13 is rotatably connected to the side limit rod 12, and the lower end of the vertical shaft 13 is fixedly connected with a blocking rod 14, which extends along the lateral direction of the support seat 4 and extends at least to the middle position of the lifting frame 9. A torsion reset device 15 and an angle sensor are connected to the vertical shaft 13 between the blocking rod 14 and the side limit rod 12, and the angle sensor transmits a signal to the controller, and the controller controls the action of the vertical displacement drive device. By setting the above structure, it can play the role of a proximity switch, wherein the angle sensor transmits a signal to the controller, and the controller controls the action of the vertical displacement drive device, so that the lifting process of the insulator 1 is smoother, and the automated lifting and disassembly work is convenient. When the blocking rod 14 rotates to a certain angle, it indicates that the lifting frame 9 has been inserted into the specified position of the insulator 1, which is convenient for reliably lifting the insulator 1. The torsion reset device 15 can adopt a torsion spring.

[0027] In this embodiment, see Figure 3 , a second push rod 16 is installed on the vertical slider 8, and the output end of the second push rod 16 is connected to the bottom plate 11, and at least two horizontal guide rods 17 are fixed on the bottom plate 11, and the horizontal guide rods 17 slide into the horizontal guide holes 18 opened on the vertical slider 8. Before the controller controls the vertical displacement drive device to lift, the controller first controls the second push rod 16 to extend the bottom plate 11 outward, and the position of the lifting frame 9 can be further adjusted according to the size of the insulator 1, and the interference between the insulator string and the sliding bracket 7 can be prevented, so that the lifting process is smoother.

[0028] In this embodiment, see Figure 2 , 3 The outer end of the side limit rod 12 is rotatably connected to the upper end of the oblique pressure rod 20 through the horizontal rotating shaft 19, and the lower end of the oblique pressure rod 20 extends obliquely downward toward the side where the sliding bracket 7 is located. An elastic support device 21 is connected between the oblique pressure rod 20 and the bottom plate 11. The lower surface of the oblique pressure rod 20 contacts the next insulator 1 that needs to be lifted. This insulator 1 is the insulator 1 to be removed. By using the oblique pressure rod 20 to press and push the insulator 1 to be removed, the insulator 1 to be removed can be separated from the insulator 1 above in the vertical direction, reducing the mutual interference between the above two insulators 1, so as to prevent the upper insulator 1 from being damaged when the lower insulator 1 is removed because the upper insulator 1 cannot be separated from the lower insulator 1. When the lower insulator 1 is removed, the oblique pressure rod 20 applies a downward lateral thrust to the lower insulator 1 to ensure that the lower insulator 1 is separated from the upper insulator 1. In this embodiment, the elastic supporting device 21 may be a spring.

[0029] In this embodiment, see Figure 5The sliding bracket 7 includes a base 22, a vertical support plate 23 and a top plate 24. The base 22 is slidably arranged on the support seat 4, and the top plate 24 is installed above the base 22 in parallel. The top plate 24 is fixed to the base 22 through the vertical support plate 23. The vertical support plate 23 is triangular, and the vertical support plate 23 connects the base 22 and the top plate 24, which also increases the overall structural strength and stability, making the movement process of the sliding bracket 7 smoother, and the center of gravity is more stable when the vertical displacement driving device is in action.

[0030] In this embodiment, see Figure 5 The vertical displacement driving device includes a first motor 25, a screw rod 26 and a vertical guide rod 27. The first motor 25 is fixed on the base 22. The output end of the first motor 25 is drivingly connected to one end of the screw rod 26. The screw rod 26 and the vertical guide rod 27 are installed in parallel and spaced between the base 22 and the top plate 24. The screw rod 26 is threadedly connected to the vertical slider 8. The vertical guide rod 27 slides through the vertical guide hole 28 provided on the vertical slider 8. When the first motor 25 is started, the vertical slider 8 can be driven to move in the vertical direction.

[0031] In this embodiment, see Figure 1 A second motor 29 is fixed at the bottom of the base 22, and a gear 30 is connected to the output end of the second motor 29, and the gear 30 is meshed with a rack 31, and the rack 31 is fixed to the outer wall of the support seat 4; a plurality of support wheels 32 are rotatably connected to the lower end of the base 22, and the support wheels 32 are arranged on both sides of the support seat 4, and the surface of the support wheels 32 abuts against the outer side of the support seat 4. Through the above structure, under the driving of the second motor 29 and the guiding action of the support wheels 32, the sliding bracket 7 can stably slide back and forth on the support seat 4 in a directional manner.

[0032] In this embodiment, see Figure 6, a slot 33 is provided on the side of the horizontal slider 5, and a top block 35 is connected to the slot 33 through a support spring 34. A through hole 36 corresponding to the slot 33 is provided on the side of the support seat 4, and a wedge block 37 is slidably provided in the through hole 36, and the inclined surface of the wedge block 37 faces the sliding bracket 7. In a normal state, the top block 35 is supported by the support spring 34 and pressed against the wedge block 37 in the through hole 36. At this time, the top block 35 can lock the support seat 4 and the horizontal slider 5 to prevent the relative displacement between the two, so that the position of the horizontal slider 5 can be fixed when the structure is not in use. When the insulator 1 needs to be replaced, after the sliding bracket 7 moves, the base 22 on the sliding bracket 7 can act on the inclined surface of the wedge block 37. After the wedge block 37 retracts inward, it acts on the top block 35 and drives the support spring 34 to deform. At this time, the contact plane of the wedge block 37 and the top block 35 coincides with the intersection plane between the support seat 4 and the horizontal slider 5, and the first push rod 6 can normally drive the horizontal slider 5 to move. In this embodiment, the base 22 is provided with limiting plates on both sides of the support base 4, so that the base 22 is in an L-shaped structure.

[0033] In the present application, the first push rod 6 and the second push rod 16 may be one or more of an electric push rod, a hydraulic cylinder and a pneumatic cylinder.

[0034] Embodiment 2: See also Figure 1 The method for using the insulator non-stop replacement device comprises the following steps: A support base 4 is installed on the transmission line tower, an insulator string is located on the support base 4 , and an insulator 1 at the lower end of the insulator string is fixed on a horizontal slider 5 .

[0035] When the insulator 1 needs to be replaced, the sliding bracket 7 is installed on the support seat 4. At this time, the lifting frame 9 is located on one side of the insulator string. After determining the insulator 1 that needs to be replaced, the height of the vertical slider 8 is adjusted by the vertical displacement drive device so that the lifting frame 9 is located between the insulator 1 that needs to be replaced and the insulator 1 on the upper side.

[0036] The sliding bracket 7 is moved toward one side of the insulator string so that the bayonet of the lifting frame 9 is engaged with the insulator 1 .

[0037] The vertical displacement driving device then adjusts the height of the vertical slider 8 to slightly lift the insulator 1 on the upper side of the insulator 1 to be replaced.

[0038] The first push rod 6 moves to pull the horizontal slider 5 outward, and the insulator 1 to be replaced moves out along with the horizontal slider 5 .

[0039] After the new insulator 1 is replaced, the first push rod 6 moves to push the horizontal slider 5 inwards, pushing the replaced insulator 1 to its original position.

[0040] The height of the vertical slider 8 is lowered by the vertical displacement drive device, and the insulator 1 on the upper side of the lifting frame 9 is gradually lowered. When the lifting frame 9 is located between the upper and lower insulators, the sliding bracket 7 is moved away from the insulator string to withdraw the lifting frame 9, and then the sliding bracket 7 is moved out.

[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
