Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, and specifically to a support structure for power transmission lines. Background Technology

[0002] When laying power transmission lines, transmission line supports are required. Traditional transmission line supports typically consist of a support structure and a bracket. The support structure provides good support for the transmission line, while the bracket helps to fix the support structure in a suitable position. While these transmission line supports do provide good support, their structure is relatively simple. They usually lack a stable mounting structure, making them prone to swaying at the bottom when encountering complex ground conditions, thus failing to provide adequate support for the transmission line. Furthermore, the support structure of these supports can typically only support one type of transmission line, resulting in a limited range of applications.

[0003] The prior art patent document CN 215419372 U discloses an auxiliary support for power transmission lines in power transmission and transformation projects. The support includes a fixed base plate, a fixed base, a support pile, a fixed arm, a line fixing structure, a lifting structure, and an installation structure. The support pile is fixedly connected to the upper surface of the fixed base, and an inner cavity is formed inside the support pile. A lifting structure is installed within the inner cavity of the support pile. An inner cavity is formed inside the fixed arm, and a line fixing structure is installed on the fixed arm. L-shaped grooves are formed on both sides of the upper surface of the fixed base plate, and inner cavities are formed on both sides of the fixed base. Installation structures are provided within the inner cavities on both sides of the fixed base. This application features a line fixing structure, which allows for convenient fixing of the external protective tube of the cable, thereby securing the cable. The operation is simple and convenient, and disassembly is also easy.

[0004] Although the device has many beneficial effects, it still has the following problems: the lifting structure of the device can only achieve linear adjustment in the vertical direction and cannot achieve multi-angle adjustment of the support arm, which makes it unsuitable for complex terrain.

[0005] Secondly, although the device is portable and easy to operate, its method of fixing the power transmission line is simple and lacks effective buffering and insulation protection, which can easily damage the outer sheath of the power transmission line. Utility Model Content

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] 1. Technical problems to be solved:

[0008] To address the aforementioned issues, although the device has good vertical adjustment capabilities, it lacks angle adjustment, has low adjustability, and poor stability.

[0009] The device is portable and easy to operate, but it lacks a reliable way to secure and protect the power lines. The power lines are prone to unstable fixing and can easily be damaged by friction with the fixing device.

[0010] Therefore, the purpose of this utility model is to provide a support structure for power transmission lines, which solves the problems of stability and adjustability of traditional power transmission line supports by linking the adjustment mechanism and the line fixing mechanism.

[0048] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0049] This utility model provides an overall structural diagram of one embodiment of a support structure for power transmission lines, including:

[0050] Please see Figures 1-5 The support structure for a power transmission line according to this embodiment includes: a support mechanism 300, an adjustment mechanism 100, and a line fixing mechanism 200.

[0051] It is worth noting that, for the purpose of adjustment, the specific adjustment mechanism 100 includes:

[0052] Fixed base 1, the basic part of the entire adjustment mechanism, is usually fixed to the ground, wall or platform by bolts;

[0053] Support column 2 is vertically inserted into the upper end of fixed base 1 and is mainly used for support and lifting height;

[0054] The support arm 4 extends laterally from the left and right sides of the support column 2 to expand the support range. After the support arm 4 is unfolded, it is inserted into the slot 104 on the side wall of the support arm 4 through the upper pin 103, so that the support arm 4 will not tip over.

[0055] Hinge 3 is welded and fixed to support column 2 and then hinged to support arm 4 for rotation to achieve angle adjustment;

[0056] The support rod 102 is inserted at both ends of the support column 2. The angle of the support arm 4 is kept stable by inserting the pin 103 at the front end of the support rod 102 into the slot 104 on the side wall of the support arm 4.

[0057] Storage slots 108 are provided at both ends of the support column 2. The support rod 102 can be stored when folded for easy transportation.

[0058] Adjusting rod 101 is used to support column 2 and support arm 4. Specifically, the connection and adjustment are achieved through the rotational engagement of hinge 3 on support column 2.

[0059] The pin 103 is tightly welded to the top of the support rod 102. When combined with the slot 202 of the support arm 4, it can be used to fix the position and lock the angle.

[0060] The slot 104 is formed on the side wall of the support arm 4 and cooperates with the pin 103. The pin 103 can achieve the fixation after angle adjustment by selecting different positions of the slot 104.

[0061] Next, in order to fix the line, specifically, the line fixing mechanism includes a base 201, which is bolted to the upper end of the support arm 4;

[0062] The slide 202 is formed on the upper end of the base 201 to provide a moving path for the slider 203;

[0063] The slider 203 is embedded in the groove 202 and can slide along the track of the groove 202. The main clamp 204 and the auxiliary clamp 205 are usually welded and fixed to the slider 203, thereby realizing the flexible adjustment of the position of the wire clamp.

[0064] The main clamp 204 clamps the main components of the power transmission line and is directly fixed to the base 201;

[0065] The auxiliary clamp 205 is a secondary component that holds the power transmission line and can slide in the slide groove 202 via the slider 203.

[0066] Meanwhile, for protection, specifically, the insulating pad 208 is bonded to the inner surface of the main clamp 204 and the auxiliary clamp 205 as a rubber or engineering plastic gasket. Its function is to prevent the metal clamps from scratching the outer sheath of the transmission line and to prevent the transmission line from sliding or shifting.

[0067] Furthermore, for the purpose of fastening, specifically, the fastening screw hole 207 is a threaded hole machined on the upper end of the main clamp 204 and the auxiliary clamp 205, which mates with the fastening bolt 206;

[0068] The fastening bolt 206, which passes through the screw holes on the auxiliary clamp 205 and the main clamp 204, generates pressure when tightened, causing the auxiliary clamp 205 to close and tightly hold the power transmission line.

[0069] Finally, for smooth movement, specifically, the pulley 107 is rotatably mounted in the slide groove 202 and connected to the support rod 102, thereby making the movement operation more effortless and smooth. The slide 106 is formed on one side of the support column 2 and the support arm 4, and the pulley 107 slides in cooperation with the slide groove 202, allowing it to slide along the slide 106 and achieve positioning.

[0070] Combination Figures 1-5 The specific usage process of the support structure for power transmission lines according to this embodiment is as follows:

[0071] 1: First, the fixed base 1 is usually fixed to the ground, wall or platform with bolts, and vertically inserted into the support column 2. Then, the support arm 2 is rotated and connected by the hinge 3.

[0072] 2: Open the secondary clamp 205, place the power transmission line into the groove of the main clamp 204, ensure that the insulating pad 208 is intact and correctly positioned, close the secondary clamp 205, insert and tighten the fastening bolt 206 until the power transmission line is firmly clamped and there is no looseness. The torque should be moderate to avoid damaging the power transmission line. If you need to add or replace the power transmission line, loosen the fastening bolt 206 to carry out the operation.

[0073] 3: Adjust the elevation angle of the support arm 4 by using the pin 103 and slot 104, or adjust the position by using the pulley 107 to slide in the slide groove 202. After determining the position, lock the position by using the fixing hole 109.

[0074] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
