A lifting device for PT connection sleeve

Abstract

This utility model discloses a lifting device for PT connecting sleeves, relating to the field of installation equipment technology. The lifting device for PT connecting sleeves includes a base and a hanger located in the middle of the top surface of the base. It also includes a slider slidably connected to the top left side of the hanger, with a fixing mechanism fixedly connected to the bottom of the slider. Through the fixing mechanism, when the device is to be used, the external PT connecting sleeve is first passed through a suspension rope, and then secured using the rope loops and fixing buckles inside the suspension rope. Next, the lifting hydraulic rod is raised, allowing the sleeve to rise with the fixing plate for further transportation.

Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a lifting device for PT connecting sleeves. Background Technology

[0002] Lifting devices for PT (voltage transformer) bushings are typically specially designed lifting tools used for the safe and efficient installation or replacement of bushings in power equipment. During the installation, maintenance, or replacement of power equipment, high-voltage PT bushings can weigh tens or even hundreds of kilograms, making them difficult to handle manually and structurally fragile. Bushings are usually made of ceramic or composite materials, which are easily damaged by impacts, tilting, or stress concentration. Therefore, PT (voltage transformer) bushings require the use of specialized lifting devices.

[0003] Existing PT connecting sleeves can weigh tens or even hundreds of kilograms, making them difficult to handle manually. Manual lifting can easily lead to slippage or tilting, potentially damaging the sleeve or injuring operators. Therefore, a fixing device is installed on the hoisting and transfer equipment to prevent tilting, loosening, and slippage during lifting and transportation, which would reduce transportation efficiency and increase the damage rate of the connecting sleeve. Furthermore, existing hoisting equipment has a relatively simple lifting method and cannot transport the sleeve to a specific location as needed, limiting the lifting range and reducing the accuracy and efficiency of transportation. Utility Model Content

[0004] This invention provides a lifting device for PT connecting sleeves to solve the problem that existing devices cannot be fixed during lifting, resulting in poor balance and easy damage and tilting of the sleeves.

[0005] This utility model provides the following technical solution: a lifting device for a PT connecting sleeve, including a base and a hanger disposed in the middle of the top surface of the base, and further including: a slider slidably connected inside the top left side of the hanger, a fixing mechanism fixedly connected to the bottom of the slider, the fixing mechanism including a hanging plate, a lifting hydraulic rod, a fixing plate and a suspension rope, a drive motor installed inside the middle section of the hanger, and a lifting mechanism fixedly connected to the top of the drive motor, the lifting mechanism including a converter, a top frame, an angle lifting assembly, a lifting rod and an extension hydraulic rod.

[0006] As a preferred embodiment of this utility model, lifting hydraulic rods are fixedly connected to both sides of the bottom surface of the suspended plate, a fixing plate is fixedly connected to the bottom of the lifting hydraulic rods, and suspension ropes are fixedly connected to both sides of the bottom surface of the fixing plate.

[0007] As a preferred technical solution of this utility model, the top of the adapter is rotatably connected to a top frame, the top of the top frame is fixedly connected to an angle lifting assembly, the middle of the top frame is rotatably connected to a lifting rod, the middle of the lifting rod is provided with a slot, and an extension hydraulic rod is slidably connected inside the slot.

[0008] As a preferred embodiment of this utility model, the angle lifting assembly includes a rotating rod fixedly connected to the top of the top frame, and a lifting hydraulic rod is fixedly connected to the top left side of the rotating rod.

[0009] As a preferred embodiment of this utility model, a rotating block is fixedly connected to the bottom surface of the lifting hydraulic rod, and a rotating fixing component is rotatably connected to the lower end of the rotating block.

[0010] As a preferred embodiment of this utility model, a support frame is fixedly connected to both sides of the top surface of the base, and a crossbar is supported on the inner side of the top surface of the support frame.

[0011] As a preferred embodiment of this utility model, the suspension rope is externally secured with a rope buckle, and a rope loop is slidably connected inside the rope buckle.

[0012] As a preferred embodiment of this utility model, the left and right sides of the base are rotatably connected to movable wheels, and the interior of the hanger extends through the outer middle section of the supporting crossbar.

[0013] Compared with the prior art, the present invention provides a lifting device for PT connection sleeves, which has the following advantages:

[0014] This lifting device for PT connecting sleeves, through the setting of a fixing mechanism, allows the external PT connecting sleeve to be passed through the suspension rope before use. The external PT connecting sleeve is then fixed in place by the rope loops and fixing buckles inside the suspension rope. Next, the lifting hydraulic rod is raised, allowing the sleeve to rise with the fixing plate for further transportation. This facilitates the fixing and lifting of the connecting sleeve, preventing it from tilting or falling off during transportation due to inability to fix it properly or insufficient fixing, which would reduce transportation efficiency and increase the damage rate of the connecting sleeve.

[0015] This lifting device for PT connecting sleeves, through the setting of the lifting mechanism, has a drive motor installed inside the middle section of the hanger when the device is to be used. The drive motor causes the top adapter to rotate with its top frame, allowing the lifting rod to rotate to transport the sleeve. At the same time, angle lifting components are installed on the top of the top frame and the top of the lifting rod, allowing the lifting rod to also adjust its angle, which increases the lifting and transportation range. This avoids the limitation of the lifting range due to a relatively single lifting angle, which cannot transport the sleeve to a specific location as needed, thus reducing the accuracy and efficiency of transportation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model discloses a lifting device for a PT connecting sleeve, including a base 1 and a hanger 2 disposed in the middle of the top surface of the base 1. It also includes: a slider 3 slidably connected inside the top left side of the hanger 2, and a fixing mechanism 4 fixedly connected to the bottom of the slider 3. The fixing mechanism 4 includes a hanging plate 401, a lifting hydraulic rod 402, a fixing plate 403, and a suspension rope 404; a drive motor 5 is installed inside the middle section of the hanger 2, and a lifting mechanism 6 is fixedly connected to the top of the drive motor 5. The lifting mechanism 6 includes a converter 601, a top frame 602, an angle lifting assembly 603, a hanging rod 604, and an extension hydraulic rod 605.

[0023] Specifically, lifting hydraulic rods 402 are fixedly connected to both sides of the bottom surface of the suspended plate 401, and a fixing plate 403 is fixedly connected to the bottom of the lifting hydraulic rods 402. Suspension ropes 404 are fixedly connected to both sides of the bottom surface of the fixing plate 403.

[0024] In this embodiment, the external PT connecting sleeve is first passed through the suspension rope 404, and the external PT connecting sleeve is fixed by the rope loop 14 and the fixing rope buckle 13 inside the suspension rope 404. Then, the lifting hydraulic rod 402 is raised so that the sleeve can be raised with the fixing plate 403 for the next step of transportation.

[0025] Specifically, the top of the adapter 601 is rotatably connected to the top frame 602, the top of the top frame 602 is fixedly connected to the angle lifting assembly 603, the middle of the top frame 602 is rotatably connected to the outside of the middle part of the top frame 602, the middle part of the lifting rod 604 is provided with a slot, and the inside of the slot is slidably connected to the extension hydraulic rod 605.

[0026] In this embodiment, a drive motor 5 is installed inside the middle section of the hanger 2. The drive motor 5 causes the top adapter 601 to rotate along with the top frame 602, allowing the boom 604 to rotate to transport the sleeve. At the same time, an angle lifting assembly 603 is installed on the top of the top frame 602 and the top of the boom 604, allowing the boom 604 to also adjust its angle.

[0027] Specifically, the angle lifting assembly 603 includes a rotating rod 7 fixedly connected to the top of the top frame 602, and a lifting hydraulic rod 8 fixedly connected to the top left side of the rotating rod 7.

[0028] In this embodiment, a rotating rod 7 is installed at the top of the top frame 602, and the rotating rod 7 is connected to the lifting hydraulic rod 8. However, a rotating block 9 and a fixing member 10 are also installed at the bottom of the lifting hydraulic rod 8, so that the lifting angle of the lifting rod 604 can be adjusted by retracting the lifting hydraulic rod 8.

[0029] Specifically, a rotating block 9 is fixedly connected to the bottom surface of the lifting hydraulic rod 8, and a rotating fixing component 10 is rotatably connected to the lower end of the rotating block 9.

[0030] Specifically, support frames 11 are fixedly connected to both sides of the top surface of the base 1, and crossbars 12 are supported on the inner side of the top surface of the support frames 11.

[0031] Specifically, the suspension rope 404 is externally secured with a rope buckle 13, and the rope buckle 13 is internally slidably connected with a rope loop 14.

[0032] Specifically, the base 1 has rotatably connected movable wheels 15 on both the left and right sides, and the interior of the hanger 2 extends through the outer middle section of the support crossbar 12.

[0033] The working principle and usage process of this utility model are as follows: When the device is to be used, first pass the external PT connecting sleeve through the suspension rope 404, and use the rope loop 14 and the fixing rope buckle 13 inside the suspension rope 404 to fix the external PT connecting sleeve. Then, lift the lifting hydraulic rod 402 so that the sleeve can be raised with the fixing plate 403 for the next step of transportation.

[0034] When the device is to be used, a drive motor 5 is installed inside the middle section of the hanger 2. The drive motor 5 causes the top adapter 601 to rotate with the top frame 602, so that the boom 604 can rotate to transport the sleeve. At the same time, an angle lifting assembly 603 is installed on the top of the top frame 602 and the top of the boom 604, so that the boom 604 can also be adjusted in angle.

[0035] In summary, the lifting device for PT connecting sleeves, through the setting of the fixing mechanism 4, facilitates the fixing of the connecting sleeves during lifting and transportation, avoiding skewing and detachment during transportation due to inability to fix them properly or insufficient fixing, thus reducing transportation efficiency and increasing the damage rate of the connecting sleeves. Furthermore, the setting of the lifting mechanism 6 increases the lifting and transportation range, preventing the limitation of the lifting range due to a single lifting angle, which cannot transport the sleeve to a specific location as needed, thus reducing the accuracy and efficiency of transportation.
