Description

Technical Field

[0001] This utility model belongs to the field of power supply engineering technology, specifically a line support device for power supply engineering. Background Technology

[0002] As a core infrastructure for energy transmission, power supply projects rely heavily on line support devices (such as pole supports, cable trench supports, overhead line crossarms, and matching clamps) as key components ensuring the stable laying and safe operation of conductors and cables. In traditional construction, fixed specifications of these support devices often lead to discrepancies between on-site and design requirements, necessitating secondary cutting, welding, or emergency replacement of spare parts, thus delaying the construction schedule. Construction units urgently need flexible and adjustable devices to reduce on-site processing steps and improve construction efficiency in complex terrain.

[0003] Meanwhile, a line support device for power supply engineering in residential communities, with application number CN202121803501.5, includes a base plate. A fixing rod is fixed to the upper surface of the base plate. A support column is slidably connected to the upper surface of the fixing rod. A disc is fixed to the outside of the fixing rod. A support block is fixed to the upper surface of the support column. A hook is fixed to the lower surface of the support block. A through groove is provided on the front end surface of the support block. An upper clamping plate and a lower clamping plate are respectively provided on the upper and lower walls of the through groove. A spring is fixedly connected to the surfaces of the upper and lower clamping plates that are close to each other. The left and right edges of the upper and lower clamping plates are fixedly connected by bolts. A sliding groove is provided inside the upper surface of the support block.

[0004] However, the following problems were found in the implementation of the relevant technology: the support device needs to be customized according to the preset height (such as 3m, 4m, 5m) and cannot be adjusted according to the site terrain. Moreover, it is only suitable for a single specification of conductor or a fixed number of line groups. When the line is upgraded, the entire clamping ring needs to be replaced, which increases the cost of the transformation. In the face of multiple parallel circuits or irregular arrangement of multiple cables in the cable trench, the fixed spacing clamping ring cannot meet the safety spacing requirements, which can easily cause phase-to-phase discharge or cable squeezing and wear.

[0005] Therefore, we propose a line support device for power supply engineering. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a line support device for power supply engineering, which has the advantages of freely adjusting the position of the retaining ring according to different numbers and radii of line groups, realizing the orderly arrangement of multiple line groups and safe spacing control, and conveniently adjusting the support height position.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a power supply line support device, comprising a main pole, an adjusting rod slidably connected inside the main pole, a notch provided on the main pole, a positioning block fixedly connected to the outer surface of the adjusting rod, a bolt fixedly connected to the outer surface of the positioning block, a threaded sleeve threadedly connected to the bolt, a support plate fixedly connected to the upper surface of the adjusting rod, a sliding groove provided on the support plate, several locking slots provided on the rear side of the sliding groove, a slider slidably connected inside the sliding groove, a double retaining ring fixedly connected to the upper surface of the slider, a recessed groove provided on the slider, a spring fixedly connected inside the recessed groove, a locking block fixedly connected to the other end of the spring, and the locking block slidably connected to the recessed groove.

[0008] Preferably, the positioning block is slidably connected to the cut.

[0009] Preferably, a control handle is fixedly connected to the outer surface of the threaded sleeve, and the control handle is provided with anti-slip texture.

[0010] Preferably, the card block is movably connected to the card slot, and the front side of the card block is rounded.

[0011] Preferably, a cover plate is fixedly connected to the sinking trough, and the cover plate is provided with a slot.

[0012] Preferably, a pull plate is fixedly connected to the upper surface of the card block, and the pull plate is slidably connected to the slot.

[0013] Preferably, a single retaining ring is fixedly connected to each side of the support plate.

[0014] Preferably, one of the double retaining rings consists of two half retaining rings facing opposite directions.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the cooperation of a support plate, slide groove, bayonet, slider, double retaining ring, recessed groove, spring and retaining block, can freely adjust the position of the retaining ring according to different numbers and radii of line groups, and can quickly realize the orderly arrangement of multiple line groups and control of safe spacing. There is no need to make secondary cutting and welding modifications to the support device, thus adapting to various wire specifications, reducing spare parts costs, and having a self-locking function to resist external disturbances and prevent sliding or loosening due to vibration, wind load, temperature difference, etc., and prevent line displacement and falling off.

[0017] 2. This utility model, through the cooperation of the main rod, adjusting rod, notch, positioning block, bolt and threaded sleeve, can easily adjust the support height position. By finely adjusting the support height on site, the line of the support point can be kept horizontal or conform to the design slope, ensuring the overall smoothness of the line. No additional support is required, which greatly reduces the construction difficulty in complex terrain areas. Attached Figure Description

[0024] 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.

[0025] like Figures 1 to 5 As shown, this utility model provides a power supply line support device, including a main rod 1, an adjusting rod 2 slidably connected inside the main rod 1, a notch 3 provided on the main rod 1, a positioning block 4 fixedly connected to the outer surface of the adjusting rod 2, a bolt 5 fixedly connected to the outer surface of the positioning block 4, a threaded sleeve 6 threadedly connected to the bolt 5, a support plate 7 fixedly connected to the upper surface of the adjusting rod 2, a sliding groove 8 provided on the support plate 7, several locking slots 9 provided on the rear side of the sliding groove 8, a slider 10 slidably connected inside the sliding groove 8, a double retaining ring 11 fixedly connected to the upper surface of the slider 10, a sinking groove 12 provided on the slider 10, a spring 13 fixedly connected inside the sinking groove 12, a locking block 14 fixedly connected to the other end of the spring 13, and the locking block 14 slidably connected to the sinking groove 12.

[0026] Specifically, the positioning block 4 is slidably connected to the cutout 3.

[0027] Furthermore, a control handle 16 is fixedly connected to the outer surface of the threaded sleeve 6 for controlling the rotation of the threaded sleeve 6, and the control handle 16 is provided with anti-slip texture.

[0028] Furthermore, the card block 14 is movably connected to the bayonet 9, and the front side of the card block 14 is rounded.

[0029] It is worth noting that a cover plate 17 is fixedly connected to the sink trough 12, and the cover plate 17 is provided with a slot to protect the connection structure of the spring 13.

[0030] It is worth noting that a pull plate 15 is fixedly connected to the upper surface of the card block 14. The pull plate 15 is slidably connected to the slot and is used to control the sliding of the card block 14.

[0031] It is worth mentioning that a single retaining ring is fixedly connected to each side of the support plate 7, which cooperates with the double retaining rings 11 on the slider 10 on the side to fix the circuit.

[0032] It is worth emphasizing that a double retaining ring 11 consists of two half retaining rings facing opposite directions, which cooperate with the double retaining rings 11 on the left and right sliders 10 to fix the circuit.

[0033] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0034] Working principle: When the height of the support plate 7 needs to be adjusted, loosen the threaded sleeve 16 on the bolt 6, and then lift the adjusting rod 2. The adjusting rod 2 slides on the notch 3 through the positioning block 4, thereby lifting the adjusting rod 2. Adjust the support plate 7 to the desired height through the adjusting rod 2. Then rotate the threaded sleeve 16. During the rotation, the locking sleeve 16 moves closer to the adjusting rod 2 through the action of the thread, thereby fixing the position of the adjusting rod 2 through the clamping force between the threaded sleeve 16 and the adjusting rod 2, and thus fixing the height position of the support plate 7. Then, first place one or a group of wires from one side of the support plate 7, with the first group of wires placed on one side of the single retaining ring. Then, the moving block 14 slides in the sinking groove 12 through the pull plate 15, thereby causing the retaining block 14 to slide back from the retaining hole 9 into the sinking groove 12. Within 2, the slider 10 can slide within the slide groove 8. Then, the position of the double retaining ring 11 is adjusted by the slider 10 sliding within the slide groove 8. After the slider 10 slides to the desired position, the pull plate 15 is released, and then the spring 13 applies elastic force to the retaining block 14, causing the retaining block 14 to slide out. The retaining block 14 slides from the sink groove 12 into the retaining slot 9, thereby locking the slider 10 in the retaining slot 9 and fixing the position of the double retaining ring 11. The double retaining ring 11 clamps and fixes the wires by clamping with the single retaining ring. Then, the wires are placed in sequence, and then the double retaining ring 11 on another slider 10 is used to fix the wires. This allows multiple sets of wires to be fixed and grouped in an orderly manner. Note that this equipment is a support structure used for temporary construction during maintenance or assembly and is not used for long-term support.
