Description

Technical Field

[0001] The invention relates to the field of insulating sheath installation, and in particular to a device for installing an insulating sheath on a live transformer pile head. Background Art

[0002] In the power system, the transformer is a vital device, which plays a key role in changing voltage and transmitting electric energy. The transformer pile head is the key part connecting the wires and the transformer. Since it is directly connected to the power line, it is usually in a live state. If the insulation performance of the transformer pile head is poor, there will be safety hazards such as leakage and short circuit, which may cause damage to power equipment and even cause serious accidents such as fire and electric shock. Therefore, installing high-quality insulation sheaths for transformer pile heads is an important measure to ensure the safe and stable operation of the power system.

[0003] In the prior art, when placing the insulating sheath at the installation position, manual adjustments are required multiple times. First, the insulating sheath must be picked up, aligned with the transformer terminal, and then slowly put on. If a position deviation occurs during this process, it needs to be readjusted, which makes the operation steps of the entire installation process very cumbersome and time-consuming. In addition, the insulating sheath installation device is not flexible enough in the design of the wire sheath part. For wires of different diameters, the device may not be able to provide suitable fixing and accommodation space.

[0004] Therefore, it is necessary to propose a live transformer pile head insulation sheath installation device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an insulating sheath installation device for live transformer pile head installation to solve the problem of multiple manual adjustments. The insulating sheath must first be picked up, aligned with the transformer pile head, and then slowly put on. If a position deviation occurs during this process, it needs to be readjusted, which makes the operating steps of the entire installation process very cumbersome and time-consuming. In addition, the insulating sheath installation device is not flexible enough in the design of the wire sheath part. For wires of different wire diameters, the device may not be able to provide suitable fixing and accommodating space.

[0006] To achieve the above object, the present invention provides the following technical solutions: A device for installing an insulating sheath at a transformer pile head under power, comprising a first installation rod, a second installation rod and a connecting rod, wherein the first installation rod and the second installation rod are connected and installed via the connecting rod, a mounting sleeve is provided at one end of the second installation rod, the bottom of the mounting sleeve is open, and the interior is a hollow structure, an insulating sheath is installed inside the mounting sleeve, the insulating sheath is trumpet-shaped, a wire sheath is installed outside the insulating sheath, and wire grooves are provided on the same horizontal line of the insulating sheath and the wire sheath, a linear motor is installed at the top of the interior of the mounting sleeve, the output end of the linear motor is connected to the top of the insulating sheath, an empty groove is provided near the top of the interior of the mounting sleeve, and the Two springs 1 are fixedly installed in the empty slot, and the springs 1 are symmetrically arranged in the empty slot. One end of the two springs 1 is connected to a clamping block, and the clamping block is triangular. The clamping block is slidably arranged on the empty slot. Two top blocks are fixedly installed on the top of the insulating sleeve, and a side of the top block close to the clamping block is provided with an inclined surface adapted to the side of the clamping block. A mounting disk 1 is installed on the outer side of the mounting sleeve, and the interior of the mounting disk 1 is a hollow structure. A driving structure is arranged inside the mounting disk 1, and the driving structure is used to drive the mounting sleeve to rotate to adjust the installation direction of the insulating sleeve and the wire sleeve. A mounting disk 2 is installed on the top of the mounting sleeve, and the mounting disk 2 is fixedly connected to the mounting disk 1.

[0007] Preferably, the driving structure includes a gear ring, which is fixedly mounted on the mounting sleeve, a motor is fixedly mounted on the bottom of the mounting plate, the motor is transmission-connected with a gear, the gear is arranged in the mounting plate, the gear ring is meshingly transmission-connected with the gear, a sliding rod is fixedly penetrated on the gear ring, sliding grooves are arranged on the upper and lower surfaces of the mounting plate, both ends of the sliding rod are slidably arranged on the sliding grooves, and a limiting ring is installed on the upper end of the sliding rod at the contact position with the sliding groove.

[0008] Preferably, a groove is provided inside the second mounting plate, a clamping ring is provided on the groove, and the clamping ring is fixedly mounted on the outer side of the mounting sleeve.

[0009] Preferably, a base is fixedly installed on both sides of the wire groove inside the wire sheath, and a spring 2 is connected to the base. One end of the spring 2 is connected to a clamping plate, and the clamping plate is rotatably installed on the inner wall of the wire sheath, and one end of the clamping plates on both sides of the wire groove abuts against each other.

[0014] Technical effects and advantages of the present invention: 1. The top block on the top of the insulating sleeve cooperates with the card block and spring inside the installation sleeve to provide a stable initial fixation for the insulating sleeve. During the installation process, even if the device is subjected to a certain vibration or shaking, the insulating sleeve will not easily fall off from the installation sleeve, which provides a guarantee for the subsequent accurate installation. The larger end of the trumpet-shaped opening makes it easier to align the transformer pile head during installation. In the actual operating environment, there may be other equipment or space restrictions around the transformer pile head. It is difficult for the operator to accurately align the sleeve with the pile head. The trumpet-shaped opening provides a larger fault tolerance space, just like a funnel. The operator only needs to roughly align the opening with the pile head to start the installation process, which greatly reduces the difficulty of alignment.

[0015] 2. The linear motor can directly push the insulating sheath to move, so that it can quickly cover the transformer pile head without manual installation, reducing the risk of safety accidents and ensuring the life safety of operators.

[0016] 3. The operator can control the installation sleeve and its internal insulating sheath and wire sheath by holding the installation rod, without having to operate close to the live transformer pile head, which greatly reduces the probability of electric shock accidents.

[0017] 4. The clamping plates on both sides of the wire trough inside the wire sheath are connected by spring 2. When the wire is placed in the wire trough, the elastic force of spring 2 enables the clamping plates to abut against each other, preventing the wire from falling off the wire sheath during installation.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides Figure 1-Figure 8The device for installing an insulating sheath of a transformer pile head with power on as shown in the figure comprises an installation rod 1, an installation rod 2, and a connecting rod 3. The installation rod 1 and the installation rod 2 are connected and installed by the connecting rod 3. An installation sleeve 4 is arranged at one end of the installation rod 2. The bottom of the installation sleeve 4 is open and the inside is a hollow structure. An insulating sheath 5 is installed inside the installation sleeve 4. The insulating sheath 5 is trumpet-shaped. A wire sheath 7 is installed on the outside of the insulating sheath 5. A wire groove 6 is arranged on the same horizontal line of the insulating sheath 5 and the wire sheath 7. A linear motor 8 is installed on the top of the inside of the installation sleeve 4. The output end of the linear motor 8 is connected to the top of the insulating sheath 5. An empty groove 9 is arranged near the top of the installation sleeve 4. A Two springs 10, springs 10 are symmetrically arranged in the empty slot 9, one end of the two springs 10 is connected to a card block 11, the card block 11 is triangular, the card block 11 is slidably arranged on the empty slot 9, two top blocks 12 are fixedly installed on the top of the insulating sheath 5, and a side of the top block 12 close to the card block 11 is provided with an inclined surface adapted to the side of the card block 11, a mounting plate 13 is installed on the outside of the mounting sleeve 4, the interior of the mounting plate 13 is a hollow structure, and a driving structure 14 is arranged inside the mounting plate 13, and the driving structure 14 is used to drive the mounting sleeve 4 to rotate to adjust the installation direction of the insulating sheath 5 and the wire sheath 7, and a mounting plate 2 15 is installed on the top of the mounting sleeve 4, and the mounting plate 2 15 is fixedly connected to the mounting plate 13; See also Figure 1-4 First, the insulating sheath 5 is placed inside the installation sleeve 4, and the wire sheath 7 outside the insulating sheath 5 is also placed together. At this time, when the insulating sheath 5 is placed in the installation sleeve 4, the top block 12 on its top will move close to the block 11 as the insulating sheath 5 moves. Since the side of the top block 12 close to the block 11 is provided with an inclined surface adapted to the side of the block 11, when the top block 12 continues to move upward, it will squeeze the block 11, so that the block 11 retracts into the empty slot 9, and at the same time compresses the spring 10 in the empty slot 9. When the top block 12 moves to a certain position, the block 11 will be stuck to the top block under the elastic force of the spring 10. The bottom of 12 is formed, thereby preliminarily fixing the insulating sheath 5 in the installation sleeve 4 to prevent the insulating sheath 5 from falling off from the installation sleeve 4 when installing the insulating sheath 5. Then the linear motor 8 pushes the insulating sheath 5 to make it cover the transformer pile head, thereby realizing the installation of the insulating sheath of the transformer pile head. When the driving structure 14 inside the installation disk 13 works, the driving structure 14 drives the installation sleeve 4 to rotate, thereby realizing the adjustment of the installation direction of the insulating sheath 5 and the wire sheath 7 to adapt to the installation requirements of the transformer pile heads at different positions and angles, thereby improving the installation efficiency, enhancing the installation stability and also ensuring the installation safety.

[0029] The driving structure 14 includes a gear ring 1401, which is fixedly mounted on the mounting sleeve 4. A motor 1402 is fixedly mounted on the bottom of the mounting plate 13. The motor 1402 is transmission-connected with a gear 1403. The gear 1403 is arranged in the mounting plate 13. The gear ring 1401 is meshed and transmission-connected with the gear 1403. A slide bar 1404 is fixedly penetrated on the gear ring 1401. Slide grooves 1406 are arranged on the upper and lower surfaces of the mounting plate 13. Both ends of the slide bar 1404 are slidably arranged on the slide grooves 1406. A limit ring 1405 is installed on the upper end of the slide bar 1404 at a contact position with the slide groove 1406. A groove 17 is arranged inside the mounting plate 2 15. A snap ring 16 is arranged on the groove 17. The snap ring 16 is fixedly mounted on the outer side of the mounting sleeve 4. See also Figure 4-6 When the motor 1402 is working, its output shaft drives the gear 1403 to rotate. As the gear 1403 rotates, the gear ring 1401 starts to rotate due to the meshing action between the gear 1403 and the gear ring 1401. The gear ring 1401 is fixedly mounted on the mounting sleeve 4, so the rotation of the gear ring 1401 drives the mounting sleeve 4 to rotate together, thereby adjusting the installation direction of the insulating sheath 5 and the wire sheath 7. During the rotation of the gear ring 1401, the sliding rod 1403 fixedly mounted on the gear ring 1401 is 04 will move with the gear ring 1401. Both ends of the slide rod 1404 are slidably set on the slide grooves 1406 on the upper and lower surfaces of the mounting plate 13. The slide rod 1404 slides in the slide groove 1406, which guides and supports the rotation of the gear ring 1401. At the same time, a limit ring 1405 is installed on the upper end of the slide rod 1404 at the contact position with the slide groove 1406. The limit ring 1405 can prevent the mounting sleeve 4 from falling off from the mounting plate 13, further ensuring the stability and reliability of the entire driving structure.

[0030] A base 18 is fixedly installed on both sides of the wire groove 6 inside the wire sheath 7, and a spring 2 19 is connected to the base 18. One end of the spring 2 19 is connected to a clamping plate 20, and the clamping plate 20 is rotatably installed on the inner wall of the wire sheath 7, and one end of the clamping plates 20 on both sides of the wire groove 6 abuts against each other; See also Figure 7 Initially, under the elastic force of the second spring 19, one end of the clamping plates 20 on both sides of the wire slot 6 abuts against each other and is in a closed state. When the transformer pile insulating sheath is installed, the wire is inserted from the end of the clamping plates 20 abutting against each other. The insertion of the wire will squeeze the clamping plates 20 on both sides, so that the clamping plates 20 overcome the elastic force of the second spring 19 and rotate outward around their rotating installation points, thereby opening a channel so that the wire can smoothly enter the wire slot 6. When the wire is completely placed in the wire sheath 7, the elastic force of the second spring 19 causes the clamping plates 20 to restore the initial state, so that the clamping plates 20 abut against each other, and the abutment of the clamping plates 20 on both sides forms a sealed space, which fixes the wire in the wire sheath 7 and prevents the wire from being pulled out of the wire sheath 7. Falling off in the middle.

[0031] A connecting seat 22 is fixedly installed on the top of the second mounting plate 15, a connecting piece 21 is fixedly installed on one end of the second mounting rod 2, and the connecting piece 21 is rotatably mounted on the connecting seat 22. The insulating sheath 5 is a hollow structure, and the wire grooves 6 are all arranged on one side of the insulating sheath 5 and the wire sheath 7; See also Figure 1 The connection seat 22 at the top of the second mounting plate 15 cooperates with the connection piece 21 at one end of the second mounting rod 2, and the connection piece 21 is rotatably mounted on the connection seat 22. This allows the second mounting rod 2 and the second mounting plate 15 to rotate relative to each other. In actual operation, the operator can change the position and direction of the installation sleeve 4 and the internal insulating sheath 5 and the wire sheath 7 by adjusting the angle of the second mounting plate 15, so as to better install the insulating sheath 5 on the transformer pile head. The insulating sheath 5 is trumpet-shaped and hollow in structure. This shape design is conducive to putting it on the transformer pile head. The larger end of the trumpet-shaped opening can be more conveniently aligned with the pile head for installation. The electric wire is installed inside the wire sheath 7 through the wire trough 6. As the installation proceeds, the pile head is gradually wrapped, which plays a good role in insulation protection, improves installation flexibility, and optimizes the convenience of installing the insulating sheath.

[0032] The connection points of the mounting rod 1, the mounting rod 2 and the connecting rod 3 are all fixedly installed with threaded joints 23, and both ends of the connecting rod 3 are provided with threads 24 adapted to the threaded joints 23. An insulating sleeve 25 is fixedly installed near the bottom of the mounting rod 1, and the insulating sleeve 25 is provided with anti-slip stripes; See also Figure 8 When connection is required, the threaded joint 23 is screwed into the corresponding threads 24 at both ends of the connecting rod 3. By rotating the threaded joint 23, it is gradually tightened in the threads 24, so that the mounting rod 1, the mounting rod 2 and the connecting rod 3 are firmly connected together. Connecting rods 3 of different specifications and lengths can be selected for different length requirements. This connection method is similar to the principle of threaded connection, and the engagement of threads is used to achieve fixation and connection between components. The connection is firm and easy to disassemble, which improves the convenience and flexibility of the device.
