Description

TECHNICAL FIELD

[0001] The present application relates to the field of insulating sheath installation, in particular to a live installation transformer stub insulating sheath installation device. BACKGROUND

[0002] In the power system, the transformer is a crucial device, which plays a key role in changing voltage, transmitting electric energy, etc. The transformer stub is a key part connecting the wire and the transformer. Since it is directly connected with the power line, it is usually in a live state. If the insulation performance of the transformer stub is poor, there will be safety hazards such as electric leakage and short circuit, which may cause damage to power equipment, and even cause fire, electric shock and other serious accidents. Therefore, installing high-quality insulating sheath for the transformer stub 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 to the installation position, manual adjustment is needed multiple times. The insulating sheath needs to be picked up first, aligned with the transformer stub, and then slowly put on. If there is a position deviation in this process, it needs to be adjusted again. This makes the operation steps of the whole installation process very cumbersome, consumes a lot of time, and the insulating sheath installation device is not flexible enough in the design of the wire sheath part. For different wire diameters, the device may not provide suitable fixing and accommodating space.

[0004] Therefore, it is necessary to provide a live installation transformer stub insulating sheath installation device to solve the above problems. SUMMARY

[0005] The present application aims to provide a live installation transformer stub insulating sheath installation device to solve the problem that manual adjustment is needed multiple times, the insulating sheath needs to be picked up first, aligned with the transformer stub, and then slowly put on. If there is a position deviation in this process, it needs to be adjusted again. This makes the operation steps of the whole installation process very cumbersome, consumes a lot of time, and the insulating sheath installation device is not flexible enough in the design of the wire sheath part. For different wire diameters, the device may not provide suitable fixing and accommodating space.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0007] The utility model provides a live installation transformer stake head insulation sheath installation device, including installation rod one, installation rod two, connecting rod, installation rod one and installation rod two are connected through connecting rod and are installed, one end of installation rod two is provided with installation sleeve, the bottom of installation sleeve is open, inside is hollow structure, the inside of installation sleeve is installed insulation sheath, insulation sheath is trumpet shape, the outside of insulation sheath is installed wire sheath, the same horizontal line of insulation sheath and wire sheath all is provided with wire slot, the inside top of installation sleeve is installed linear motor, the output of linear motor is connected with the top of insulation sheath, the position of inside top of installation sleeve is provided with empty slot, two spring no.

[0008] Preferably, the driving structure includes a gear ring fixedly installed on the installation sleeve, a motor fixedly installed at the bottom of the installation disc one, a gear wheel in transmission connection with the motor and arranged in the installation disc one, the gear ring in transmission connection with the gear wheel in meshing, a slide rod fixedly provided on the gear ring, slide grooves provided on the upper and lower surfaces of the installation disc one, the slide rod in sliding connection with the slide grooves, and a limiting ring installed on the upper end of the slide rod in contact with the slide grooves.

[0009] Preferably, the installation disc two is internally provided with a recess, and a snap ring is arranged on the recess and fixedly installed on the outside of the installation sleeve.

[0010] Preferably, the wire slot is fixedly installed with a base on both sides, a spring two is connected to the base, one end of the spring two is connected with a clamping plate, 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 slot abuts against each other.

[0011] Preferably, the installation disc two is fixedly installed with a connecting seat at the top, and one end of the installation rod two is fixedly installed with a connecting piece rotatably installed on the connecting seat.

[0012] Preferably, the insulation sheath is in a hollow structure, and the wire slots are arranged on one side of the insulation sheath and the wire sheath.

[0014] Preferably, an insulating sleeve is fixedly arranged on the first mounting rod near the bottom, and the insulating sleeve is provided with anti-skid stripes.

[0015] Technical effects and advantages of the present application:

[0016] 1. The cooperation of the top block at the top of the insulating sleeve and the clamping block and spring one in the inner part of the mounting sleeve provides stable preliminary fixation for the insulating sleeve. In the installation process, even if the device is subjected to certain vibration or shaking, the insulating sleeve will not easily fall off from the mounting sleeve, which provides protection for subsequent accurate installation. The larger end of the trumpet-shaped opening makes it easier to align the transformer stub during installation. In the actual operating environment, there may be other equipment or space limitations around the transformer stub, and it is difficult for the operator to accurately align the sleeve with the stub. The trumpet-shaped opening provides more fault tolerance space, like a funnel. The operator only needs to roughly align the opening with the stub to start the installation process, greatly reducing the difficulty of alignment.

[0017] 2. The linear motor can directly push the insulating sleeve to move and quickly cover the transformer stub, without the need for manual installation, which reduces the risk of safety accidents and ensures the safety of the operator.

[0018] 3. The operator can control the mounting sleeve, the insulating sleeve inside it, and the wire sleeve by holding the mounting rod, without the need for close-range operation near the live transformer stub, greatly reducing the probability of electric shock accidents.

[0019] 4. The clamping plates on both sides of the wire slot in the wire sleeve are connected by spring two. When the wire is placed in the wire slot, the elastic force of spring two allows the clamping plates to abut against each other, preventing the wire from falling out of the wire sleeve during installation.

An installation disc 1 3 is installed on the outside of the installation sleeve 4. The inside of the installation disc 1 3 is a hollow structure. A driving structure 14 is arranged in the inside of the installation disc 1 3. The driving structure 14 is used to drive the installation sleeve 4 to rotate to adjust the installation direction of the insulating sheath 5 and the wire sheath 7. An installation disc 2 15 is installed at the top of the installation sleeve 4. The installation disc 2 15 is fixedly connected to the installation disc 1 3.

[0031] Please refer to Figures 1-4 Firstly, the insulating sheath 5 is placed in the inside of the installation sleeve 4. The wire sheath 7 on the outside of the insulating sheath 5 is also placed. When the insulating sheath 5 is placed in the installation sleeve 4, the top block 12 at the top of the insulating sheath 5 will move close to the clamping block 11 with the movement of the insulating sheath 5. Since the slope is provided on the side of the top block 12 close to the clamping block 11, when the top block 12 continues to move upwards, the clamping block 11 will be pressed, so that the clamping block 11 is retracted into the empty groove 9, and the spring 1 in the empty groove 9 is compressed. When the top block 12 moves to a certain position, the clamping block 11 will clamp the bottom of the top block 12 under the elastic force of the spring 1, so as to preliminarily fix the insulating sheath 5 in the installation sleeve 4, preventing the insulating sheath 5 from falling off the installation sleeve 4 when the insulating sheath 5 is installed. Then, the linear motor 8 pushes the insulating sheath 5 to cover the transformer pile head, so as to realize the installation of the insulating sheath of the transformer pile head. When the driving structure 14 in the inside of the installation disc 1 3 works, the driving structure 14 drives the installation sleeve 4 to rotate, so as to adjust the installation direction of the insulating sheath 5 and the wire sheath 7, to adapt to the installation requirements of the transformer pile head at different positions and angles, to improve the installation efficiency, to enhance the installation stability, and to ensure the installation safety.

[0032] The driving structure 14 comprises a tooth ring 1401 fixedly installed on the mounting sleeve 4, the bottom of the mounting disc one 13 is fixedly installed with a motor 1402, the motor 1402 is drivingly connected with a gear 1403, the gear 1403 is arranged in the mounting disc one 13, the tooth ring 1401 is in meshing transmission connection with the gear 1403, the tooth ring 1401 is fixedly provided with a sliding rod 1404, the upper and lower surfaces of the mounting disc one 13 are provided with sliding grooves 1406, the two ends of the sliding rod 1404 are slidingly arranged on the sliding grooves 1406, the upper end of the sliding rod 1404 in contact with the sliding grooves 1406 is installed with a limiting ring 1405, the inside of the mounting disc two 15 is provided with a groove 17, the groove 17 is provided with a clamping ring 16, and the clamping ring 16 is fixedly installed on the outside of the mounting sleeve 4;

[0033] Please refer to Figures 4-6 When the motor 1402 works, the output shaft drives the gear 1403 to rotate, with the rotation of the gear 1403, due to the meshing effect of the gear 1403 and the tooth ring 1401, the tooth ring 1401 will start to rotate, and since the tooth ring 1401 is fixedly installed on the mounting sleeve 4, the rotation of the tooth ring 1401 will drive the mounting sleeve 4 to rotate together, so as to realize the adjustment of the installation direction of the insulating sheath 5 and the wire sheath 7. In the process of rotating the tooth ring 1401, the sliding rod 1404 fixedly provided on the tooth ring 1401 will move together with the tooth ring 1401, the two ends of the sliding rod 1404 are slidingly arranged on the sliding grooves 1406 on the upper and lower surfaces of the mounting disc one 13, the sliding rod 1404 slides in the sliding grooves 1406, which plays a guiding and supporting role for the rotation of the tooth ring 1401, at the same time, the upper end of the sliding rod 1404 in contact with the sliding grooves 1406 is installed with a limiting ring 1405, the limiting ring 1405 can prevent the mounting sleeve 4 from falling off from the mounting disc one 13, further ensuring the stability and reliability of the whole driving structure.

This allows the mounting rod two 2 and the mounting disc two 15 to be relatively rotatable. In actual operation, the operator can adjust the angle of the mounting disc two 15 to change the position and direction of the mounting sleeve 4 and the internal insulation sheath 5 and the wire sheath 7, so as to better install the insulation sheath 5 on the transformer pile head. The insulation sheath 5 is in a horn shape and a hollow structure, which is beneficial to the installation of the insulation sheath 5 on the transformer pile head. The larger end of the horn-shaped opening can be more conveniently aligned with the pile head for installation. The electric wire is installed in the wire sheath 7 through the wire slot 6. As the installation proceeds, the pile head is gradually wrapped, thereby playing a good insulation protection role and improving the installation flexibility and optimizing the installation convenience of the insulation sheath.

[0039] Threaded joints 23 are fixedly installed at the connection positions of the mounting rod one 1, the mounting rod two 2 and the connecting rod 3, threads 24 matched with the threaded joints 23 are arranged at the two ends of the connecting rod 3, an insulating sleeve 25 is fixedly installed on the mounting rod one 1 close to the bottom, and anti-skid stripes are arranged on the insulating sleeve 25;
