Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete pole plugging, and in particular to a concrete pole top plugging device. BACKGROUND

[0002] In power transmission systems, especially in 35kV and 110kV grade transmission lines, reinforced concrete poles (also known as cement poles or concrete poles) are widely used. After long-term service, the original cement plugging at the top of these concrete poles may be hollowed out due to the influence of the natural environment, which is usually defined as a general defect in the defect management standard. This top hollow can cause the internal bolts to be directly exposed to the outside, making them prone to corrosion, and in severe cases, the bolts may break, causing the overhead ground wire to fall off, which may eventually cause the circuit to trip, threatening the safe and stable operation of the power grid. The traditional repair method is to use cement to plug again, but this method is not only time-consuming and labor-intensive, but also inefficient.

[0003] Therefore, it is necessary to find a more efficient and safer way to deal with the problem of hollowing out the top of the concrete pole. This is not only an important measure to improve the reliability of the power transmission system, but also a key to reducing maintenance costs and improving work efficiency. SUMMARY

[0004] This section aims to summarize some aspects of the embodiments of the present application and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of the specification to avoid obscuring the purpose of this section, abstract and title, and such simplifications or omissions cannot be used to limit the scope of the present application.

[0005] In view of the above problems of using cement to plug the concrete pole, however, this method is not only time-consuming and labor-intensive, but also inefficient, the present application is proposed.

[0006] Therefore, the purpose of the present application is to provide a concrete pole top plugging device.

[0012] As a preferred scheme of the concrete rod top plugging device, the top cover is made of stainless steel.

[0013] As a preferred scheme of the concrete rod top plugging device, the connecting piece comprises a sealing gasket arranged between the elastic sleeve and the top cover, the sealing gasket is arranged in an "I" shape, and the limiting grooves are formed between the sealing gaskets and are extruded at the top end of the elastic sleeve.

[0014] As a preferred scheme of the concrete rod top plugging device, the connecting piece further comprises a rivet rod arranged in the elastic sleeve, the end of the rivet rod is riveted with the top cover through the wider outer extension edge at the top end of the sealing gasket, and the connecting position of the sealing gasket and the top cover is glued.

[0015] As a preferred scheme of the concrete rod top plugging device, the spiral support comprises a spiral strip arranged in the elastic sleeve, the middle of the spiral strip is hollow and arranged with a telescopic spring, the end of the telescopic spring is provided with a pull rope, and the pull rope extends through the entire spiral strip to the outside.

[0016] As a preferred scheme of the concrete rod top plugging device, the spiral strip is folded into a cylindrical shape to support the elastic sleeve, and the clamping groove and the clamping block on the spiral strip are used for limiting the up-down sliding.

[0017] As a preferred scheme of the concrete pole top sealing device, the spiral strip is folded into a cylindrical shape and then punched into a fixed block to reduce transverse slipping and increase the firmness of the connection.

[0018] The present application has the following advantages: The present application uses a UAV or other hoisting equipment and an improved grappling hook design to achieve rapid hoisting and precise positioning of the sealing assembly, avoiding the cumbersome process of traditional manual climbing of the concrete pole for sealing. The use of spiral support members and elastic sleeves allows the sealing device to quickly adapt to concrete poles of different diameters, simplifying the sealing operation process. The sealing device can be assembled and launched on the ground, eliminating the need for workers to directly climb the concrete pole for high-altitude work, greatly reducing labor intensity and work risk. The buzzer light serves as a warning device to remind the operator whether the sealing device is securely fixed, further ensuring the safety of the operation. The stainless steel top cover is treated with a reflective coating, which not only enhances its waterproof, wear-resistant, and temperature-resistant properties, but also reflects sunlight, making it easier to identify and locate. The combination of elastic sleeves and spiral support members ensures that the sealing device can tightly fit the top of the concrete pole, effectively preventing rainwater penetration and device detachment caused by strong winds, improving the durability and reliability of the sealing effect. Compared to traditional cement sealing methods, the sealing device of the present application reduces material consumption and labor costs, is highly reusable, and reduces overall construction costs. The design is simple, easy to disassemble and maintain, reducing the workload and cost of subsequent maintenance. In summary, the present application not only solves many problems in traditional sealing methods, but also significantly improves work efficiency, operational safety, and sealing quality, while reducing construction costs, with obvious economic and social benefits.

[0036] Embodiment 1, refer to Figure 1 For the first embodiment of the present application, the embodiment provides a concrete pole top sealing device, comprising a component designed for sealing the top of the concrete pole 205, which includes a hoisting assembly 100. The hoisting assembly 100 is composed of a mounting plate 101 and a fixed plate 102 fixed thereon, and the top end of the fixed plate 102 is provided with a grappling hook 103 for cooperation with a drone or other hoisting equipment to hoist the sealing device to the designated top of the concrete pole.

[0037] Specifically, the hoisting assembly 100 includes a mounting plate 101 and a fixed plate 102 provided at the top end of the mounting plate 101, the mounting plate 101 is used for connecting with the bottom sealing device, and the top end of the fixed plate 102 is provided with a grappling hook 103 for hoisting the sealing device. The core of the sealing device is the design of the stainless steel top cover 201 and the anti-sealing assembly 200. The stainless steel top cover 201 is treated with reflective light, which not only has the properties of waterproof, wear-resistant and temperature-resistant, but also reflects light under the sun, which is helpful for identification and positioning. The inside of the anti-aging spiral support 204 is equipped with a spring lining, so that the device can be adjusted by pulling the rope 204c to shrink to adapt to concrete poles 205 of different diameters.

[0038] Operation process: Ensure that all components are intact, check whether the pull rope 204c is firmly connected to the spiral support 204. Connect the mounting plate 101 of the hoisting assembly 100 with the top cover 201, and the grappling hook 103 on the fixed plate 102 is used to connect with the hoisting equipment. Use a drone or other hoisting tool to lift the entire sealing device to the top of the target concrete pole 205 through the grappling hook 103 on the fixed plate 102. When the sealing device reaches the designated position, use the drone or other means to put the device on the top of the concrete pole 205 and ensure the correct position. Pull out the pull rope 204c from the ground until the elastic sleeve 203 is tightly attached to the surface of the concrete pole 205, continue to pull the pull rope 204c until the spiral support 204 automatically falls off, at this time the sealing device has been firmly fixed on the top of the concrete pole 205. Check whether the sealing device is tightly attached to the top of the concrete pole 205 to ensure good sealing effect and prevent rainwater from seeping in and the device from falling off due to strong wind.

[0039] Through the above steps, the operator can complete the deployment and fixation of the sealing device on the ground without climbing, which not only improves the work efficiency but also ensures the safety of the operator.

[0040] Embodiment 2, reference Figures 1 to 3 For the second embodiment of the application, which is different from the first embodiment: on the basis of embodiment 1, the detailed design of the grappling hook 103 is added, aiming to reduce the shaking during the use of the unmanned aerial vehicle for hoisting and improve the positioning accuracy of the plugging assembly 200 through the positioning effect of the grappling hook 103. In addition, a buzzer light 106 is also added as a warning device.

[0041] Specifically, the grappling hook 103 is symmetrically arranged with the central axis of the fixed plate 102, the top ends between the two grappling hooks 103 form a limiting groove 104 for positioning, and the grappling hooks 103 are arranged in an arc shape, symmetrically distributed with the central axis of the fixed plate 102, and the top ends between the two grappling hooks form a limiting groove 104 for more stable connection with the unmanned aerial vehicle or other hoisting equipment.

[0042] Further, the bottom end of the grappling hook 103 is provided with a pressing plate 105, one end of the pressing plate 105 is connected with the fixed plate 102, and the pressing plate 105 is arranged in an arc shape. The grappling hook 103 and the pressing plate 105 are both designed in an arc shape, which can better adapt to the shape of the hoisting equipment and reduce the shaking caused by factors such as wind during hoisting. The pressing plate 105 is installed at the bottom end of the grappling hook 103 and connected with the fixed plate 102, and the arc design helps to increase the stability of contact with the hoisting equipment.

[0043] Further, the hoisting assembly 100 further comprises a buzzer light 106 arranged at the top end of the mounting plate 101, the buzzer light 106 is located between the threaded rods, and the pressing angle of the pressing plate 105 is used in conjunction with the buzzer light 106 to warn the user to grasp firmly. The buzzer light 106 is arranged at the top end of the mounting plate 101 and located between the threaded rods. When the unmanned aerial vehicle is connected with the grappling hook 103, the pressing plate 105 is pressed to a certain angle, the buzzer light 106 is started, prompting the user to grasp firmly and reliably.

[0044] The remaining structures are the same as those of embodiment 1.

[0045] Operation process: confirm that all components are in good condition, especially check whether the pull rope 204c is firmly connected to the spiral support 204. Check whether the limiting groove 104 of the grappling hook 103 is clean and free of foreign matter to ensure that the hoisting equipment can be smoothly clamped. Test whether the buzzer light 106 is working normally. Connect the mounting plate 101 of the hoisting assembly 100 with the stainless steel top cover 201. Use the pressing plate 105 to ensure that the connection between the grappling hook 103 and the fixed plate 102 is stable. Connect the unmanned aerial vehicle or other hoisting equipment to the limiting groove 104 of the grappling hook 103. Observe whether the buzzer light 106 is started to confirm whether the grasping is firm. If the buzzer light 106 is on, it means that the grasping has been in place; if it is not on, it needs to be adjusted again until the buzzer light 106 is started.

[0046] Positioning phase: use a drone or other lifting tools to lift the entire sealing device to the top of the target concrete pole 205. When the sealing device approaches the designated position, pay attention to its stability to ensure that it does not deviate from the target position due to shaking. When the sealing device reaches the designated position, accurately set the device on the top of the concrete pole 205 by drone or other means. Pull out the pull rope 204c from the ground until the elastic sleeve 203 is tightly attached to the surface of the concrete pole 205, continue to pull the pull rope 204c until the spiral support 204 automatically falls off. Check if the sealing device is tightly attached to the top of the concrete pole 205 to ensure good sealing effect and prevent rainwater from seeping in and the device from falling off due to strong wind. Through these improvements and operation steps, the shaking of the sealing assembly 200 during lifting can be effectively reduced, the positioning accuracy can be improved, and the safety and reliability of lifting can be ensured through the buzzer 106 warning function.

In particular, the shape of the elastic sleeve 203 is maintained by the design of the spiral support 204, and the spiral support 204 is adjusted to adapt to concrete poles 205 of different diameters.

[0048] Specifically, the sealing assembly 200 includes a mounting plate 101 connected to the top cover 201 by a threaded rod at the bottom end, the bottom end of the top cover 201 is connected to the elastic sleeve 203 through the adapter 202, the inside of the elastic sleeve 203 is installed with the spiral support 204, the spiral support 204 can support the expansion force generated by the elastic sleeve 203, so that the spiral support 204 maintains a cylindrical shape to facilitate wrapping the concrete pole 205 later.

[0049] Further, the top cover 201 is made of stainless steel, which has high corrosion resistance and strength, and is suitable for long-term outdoor use.

[0050] Further, the adapter 202 includes a sealing gasket 202a arranged between the elastic sleeve 203 and the top cover 201, the sealing gasket 202a is arranged in a "I" shape, and the sealing gasket 202a forms a limiting groove to extrude the top end of the elastic sleeve 203, wherein the sealing gasket 202a is in the shape of "I" to form a limiting groove to fix the top end of the elastic sleeve 203, and a rivet rod 202b passes through the sealing gasket 202a and is riveted with the top cover 201 to enhance the stability of the overall structure.

[0051] Further, the adapter 202 further comprises a riveting rod 202b arranged inside the elastic sleeve 203, the end of the riveting rod 202b is riveted with the top cover 201 through the wider outer extension edge of the top end of the sealing gasket 202a, and the connecting part of the sealing gasket 202a and the top cover 201 is glued, which has certain elasticity and deformation ability, and can closely fit the concrete rod 205 with different diameters.

[0052] Further, the spiral support 204 comprises a spiral strip 204a arranged inside the elastic sleeve 203, the middle of the spiral strip 204a is hollow to arrange the telescopic spring 204b, the end of the telescopic spring 204b is arranged with the pull rope 204c, and the pull rope 204c extends through the whole spiral strip 204a to the outside.

[0053] Further, the spiral strip 204a is folded into a cylindrical shape to support the elastic sleeve 203, and is limited for sliding up and down through the clamping groove 204d and the clamping block 204e on the spiral strip 204a.

[0054] Further, the spiral strip 204a is folded into a cylindrical shape and is formed into a fixed block 204f through stamping to reduce transverse slipping and increase the firmness of the connection, the spiral strip 204a is folded into a cylindrical shape to support the elastic sleeve 203, and is limited for sliding up and down through the clamping groove 204d and the clamping block 204e. The fixed block 204f is formed through stamping to reduce transverse slipping and increase the firmness of the connection.

[0055] The remaining structures are the same as those of Example 2.

[0056] Operation process: the top cover 201 is connected with the mounting plate 101 through the threaded rod. The sealing gasket 202a in the adapter 202 is placed between the top cover 201 and the elastic sleeve 203, and is fixed by riveting the rod 202b, ensuring that the sealing gasket 202a is glued between the top cover 201.

Ensure that the position of the sealing assembly is correct to avoid deviation during hoisting. When the sealing assembly reaches the specified position, place the device on the top of the concrete pole 205 by the drone or other ways. Pull the pull rope 204c from the ground, so that the spiral support 204 changes from a cylindrical shape to a strip shape, and the elastic sleeve 203 retracts to adapt to concrete poles 205 of different diameters when it lacks support. Continue to pull the pull rope 204c until the elastic sleeve 203 is tightly attached to the surface of the concrete pole 205, and the spiral strip 204a and the telescopic spring 204b support the elastic sleeve 203, and the clamping groove 204d and the clamping block 204e limit the position to prevent excessive pressure from causing up and down sliding, and the punched fixed block 204f can reduce transverse slipping, and the overall connection is more stable. When pulling the pull rope 204c, the clamping groove 204d and the clamping block 204e will not limit the pulling, and the pulling force is greater than the punched fixed block 204f, at which time the sealing device has been firmly fixed on the top of the concrete pole 205. Check whether the sealing device is tightly attached to the top of the concrete pole 205 to ensure good sealing effect and prevent rainwater from seeping in and the device from falling off due to strong winds. Through the above design and operation steps, the rapid sealing of the top of the concrete pole can be effectively realized, and the stability and reliability of the device are ensured.
