Description
Technical Field
[0001] The utility model relates to the technical field of cable suspension devices, and specifically relates to a cable suspension device for a power transmission tower. Background Technique
[0002] Cable suspension is an important link in power transmission and distribution. Its standards and requirements are crucial for ensuring the safe and stable operation of cables. Cable suspension must ensure that the cable is not affected by mechanical damage, chemical corrosion or electrical faults during operation to guarantee the safe operation of the power system. For medium and low voltage cables, cable racks are usually used to suspend them on power poles. This method has strong durability and rust resistance and can maintain stable performance in harsh environments.
[0003] Among the existing cable suspension devices, the relatively common one is the cable clamp, which usually consists of two semi-circular hoop structures. The two parts are connected by bolts to clamp the cable therein. Then, the connected device is connected to the power transmission tower to complete the cable suspension. However, when using the above device, it is necessary to align the through holes on the two semi-circular hoop structures so that the bolts can pass through both to complete the connection. And usually, there is no connection measure between the bolts, nuts and the hoop body. This leads to that during suspension, not only the hoop body needs to be fixed, but also the bolts and nuts need to be fixed, making it difficult for power workers to free their hands for other operations. Moreover, since the above process occurs at high altitude, the cable suspension is very inconvenient. Therefore, in view of the above problems, a cable suspension device for a power transmission tower is proposed herein. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a cable suspension device for a power transmission tower. The cable suspension device places the threaded cylinder and the connecting bolts used to connect the upper clamping ring and the lower clamping ring in the upper clamping ring and the lower clamping ring respectively, so that power workers do not need to be equipped with external bolts and nuts during connection, which can liberate the workers' hands to a certain extent. In addition, before bolt connection, workers can insert the insertion cylinder into the upper clamping ring to realize the preliminary connection between the upper clamping ring and the lower clamping ring. And under the clamping action of the card and the card slot, the upper clamping ring and the lower clamping ring cannot be separated, which can further liberate the workers' hands and there is no need to fix the positions of the upper clamping ring and the lower clamping ring by hand. Only need to tighten the connection bolt interface, which greatly reduces the operation difficulty of workers, and solves the technical problems in the prior art that workers need to align the through holes on the two semi-circular hoop structures and then use threaded connection, and also need to fix the bolts and nuts additionally during suspension, making it difficult to free their hands for other operations, resulting in very inconvenient cable suspension.

[0018] In a possible implementation, an anti - detachment sleeve is threadedly connected to the limiting cylinder, and an elastic rubber sheet for contacting the nut of the connecting bolt is arranged inside the anti - detachment sleeve.

Specific embodiments
[0030] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:
[0031] As Figure 1 - Figure 3 shown, a cable suspension device for a power transmission tower provided in this embodiment includes an upper clamping ring 1 and a lower clamping ring 2 for clamping and fixing a cable, a plug-in connection seat 3 provided on the upper clamping ring 1, a plug-in connector 4 provided on the lower clamping ring 2, and a suspension bracket 5 provided on the upper clamping ring 1 for connecting to the power transmission tower. Among them, the plug-in connection seat 3 includes a threaded barrel 31 and a card slot 32 opened in the upper clamping ring 1, and the plug-in connector 4 includes a plug-in barrel 41 fixedly connected to the lower clamping ring 2. Cards 42 are provided on both sides of the plug-in barrel 41. A connection bolt 43 that can be threadedly connected to the threaded barrel 31 is slidably provided in the plug-in barrel 41, and an anti-disengagement piece 431 is provided on the connection bolt 43. Through the above structural form, the threaded barrel 31 and the connection bolt 43 that play a role in connecting the upper clamping ring 1 and the lower clamping ring 2 are respectively placed in the upper clamping ring 1 and the lower clamping ring 2, so that power workers do not need to be equipped with external bolts and nuts during connection, which can liberate the hands of workers to a certain extent.
[0032] In addition, before the bolt connection, the worker can achieve the preliminary connection between the upper clamping ring 1 and the lower clamping ring 2 by inserting the insertion cylinder 41 into the upper clamping ring 1. And under the clamping action of the card 42 and the clamping groove 32, the upper clamping ring 1 and the lower clamping ring 2 cannot be separated, which can further liberate the worker's hands and there is no need to fix the positions of the upper clamping ring 1 and the lower clamping ring 2 by hand. Only the connection bolt 43 interface needs to be tightened, greatly reducing the operation difficulty of the worker.
[0033] As Figure 3 shown, a limiting cylinder 44 is fixedly arranged on the lower end surface of the lower clamping ring 2, and a limiting groove 45 for the anti-slip piece 431 to slide is formed in the limiting cylinder 44. Through the above structural form, the sliding range of the anti-slip piece 431, that is, the moving range of the connection bolt 43, can be restricted by the limiting cylinder 44. While not affecting its bolt connection with the threaded cylinder 31, it can also prevent it from sliding out of the limiting cylinder 44 and separating from the lower clamping ring 2.
[0034] In addition, the card 42 is a sheet structure made of an elastic material, and a clamping convex 421 that can fit with the clamping groove 32 is fixedly arranged on its outer side surface. Through the above structural form, when the insertion cylinder 41 is inserted into the upper clamping ring 1, the card 42 is pressed and bent without hindering the insertion of the insertion cylinder 41. When the clamping convex 421 moves to the clamping groove 32, it will be clamped into the clamping groove 32 to complete the preliminary connection between the upper clamping ring 1 and the lower clamping ring 2, facilitating the worker to free both hands.
[0035] As Figure 4 shown, mating grooves 8 are formed on both the upper clamping ring 1 and the lower clamping ring 2 to allow the insertion cylinder 41 and the connection bolt 43 to pass through and make sliding contact. Through the above structural form, it provides a necessary structural basis for the clamping action between the insertion cylinder 41 and the upper clamping ring 1 and the threaded connection between the connection bolt 43 and the upper clamping ring 1.
[0036] As Figure 3 shown, a connection backing plate 33 surrounding the mating groove 8 is fixedly arranged on the upper clamping ring 1. Lapping feet 311 are fixedly connected to both sides of the threaded cylinder 31, and the lapping feet 311 are fixedly connected to the connection backing plate 33. Through the above structural form, it can make the threaded cylinder 31 and the upper clamping ring 1 have sufficient contact area, making the pressure have a larger acting area and being able to avoid local deformation of the upper clamping ring 1.
[0037] As Figure 4As shown in the figure, a centrally arranged reinforcing rib 11 is fixedly provided on the lower end surface of the upper clamping ring 1. The suspension bracket 5 includes a connecting vertical plate 51 fixedly connected to the reinforcing rib 11. A horizontal hanging bracket 52 with an installation hole 53 is fixedly connected to the connecting vertical plate 51. Through the above structural form, the force transmission area between the connecting vertical plate 51 and the upper clamping ring 1 can be increased by the reinforcing rib 11, which can effectively prevent the upper clamping ring 1 from deforming due to excessive local stress. At the same time, the horizontal hanging bracket 52 provides a necessary structural basis for the fixed connection between the overall interface and the power transmission tower.
[0038] In addition, clamping grooves 71 are provided on the inner walls of both the upper clamping ring 1 and the lower clamping ring 2. Elastic contact cushions 7 are attached to the inner walls of the upper clamping ring 1 and the lower clamping ring 2. The contact cushions 7 are clamped in the clamping grooves 71 through annular outward protrusions. Through the above structural form, the firmness of the connection between the cable and the upper clamping ring 1 and the lower clamping ring 2 can be increased by the provided contact cushions 7. At the same time, it can also prevent the upper clamping ring 1 and the lower clamping ring 2 from directly contacting the cable, resulting in cable abrasion.
[0039] As Figure 1 - Figure 3 As shown in the figure, a retaining sleeve 6 is threadedly connected to the limiting cylinder 44. An elastic rubber sheet for contacting the nut of the connecting bolt 43 is provided inside the retaining sleeve 6. Through the above structural form, when the retaining sleeve 6 is tightened, it can improve the anti-loosening performance of the connecting bolt 43 by applying pressure to the nut of the connecting bolt 43.
[0040] The working principle and process of the present utility model:
[0041] The threaded cylinder 31 and the connecting bolt 43 used to connect the upper clamping ring 1 and the lower clamping ring 2 are respectively placed in the upper clamping ring 1 and the lower clamping ring 2, so that power workers do not need to be equipped with external bolts and nuts during connection, which can liberate the workers' hands to a certain extent.
[0042] In addition, before bolt connection, workers can achieve the preliminary connection between the upper clamping ring 1 and the lower clamping ring 2 by inserting the insertion cylinder 41 into the upper clamping ring 1. And under the clamping action of the card 42 and the card slot 32, the upper clamping ring 1 and the lower clamping ring 2 cannot be separated, which can further liberate the workers' hands. There is no need to fix the positions of the upper clamping ring 1 and the lower clamping ring 2 by hand anymore. Only the connection bolt 43 interface needs to be tightened, greatly reducing the operation difficulty of the workers.
[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
