Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a wire stringing mechanism. Background Art

[0002] During power line installation in mountainous areas, due to the terrain, ground wires often rub against soil, rocks, and other structures at the point of exit. This direct contact and friction between the cables and the soil and rocks generates significant heat, which can damage the cables due to excessive heat. Furthermore, the installation process can be interrupted for various reasons at any time, and restarting the installation can cause the ground wires to deform due to compression, further increasing wear. To address this issue, current installations typically place wooden planks at the point of friction to prevent direct contact between the cables and soil and rocks. However, this friction still generates significant heat, which can lead to cable damage. Utility Model Content

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; the structures described in various embodiments can be freely combined without any conflict in structure or principle.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., etc., are used solely for distinction and description, and should not be construed as indicating or implying relative importance.

[0026] The utility model proposes a wire-string mechanism, such as Figure 1 As shown, it includes: a base 1 and a frame 2, wherein the base 1 includes a fixing module 101 and an adjustment module 102; the fixing module 101 is fixed on the ground. For example, when installed on soil terrain, the fixing module 101 includes a steel needle, and the sharp part at the bottom is inserted into the ground to play a fixing role; when installed on rock geology, the fixing module 101 includes an anchor rod, and a hole is first drilled on the rock with a drilling tool, and then the anchor rod is implanted.

[0027] The adjustment module 102 is connected to the frame 2 and the fixing module 101 respectively, so that the position of the frame 2 can be adjusted and locked relative to the base 1. Figure 4 and Figure 5 As shown, the frame 2 is rotatably connected to the rolling element 3 via a pin. For example, the rolling element 3 comprises a grooved wheel, preferably having a U / H-shaped cross-section, to better position the cable. It should be understood that the number of cable stringing mechanisms installed can be determined based on the length of the on-site wiring, etc.

[0028] With this solution, the cable is mounted on the rolling body 3, and when the cable moves, it drives the rolling body 3 to rotate, thereby avoiding a large amount of frictional heat generated between the cable and the rolling body 3; in addition, by adjusting the relative position of the frame 2 and the base 1, the contact position and angle of the cable and the rolling body 3 can be adjusted according to specific working conditions, further reducing the friction between the cable and the rolling body 3 and extending the service life of the cable.

[0029] As a preferred solution, Figure 1As shown, the angle between the frame 2 and the base 1 is adjustable and lockable, and the angle is the angle between the frame 2 and the ground. Figure 1 In the display state, the angle is 90 degrees. Figure 2 and Figure 3 As shown, the adjustment module 102 of the base 1 includes a bottom plate 1021 and two vertical plates 1022 fixed on the bottom plate 1021. At least two first positioning holes 1023 are provided on the vertical plates 1022, and each first positioning hole 1023 is distributed on the same arc, and the arc is concentric with the rotating shaft 4. Figure 4 As shown, the frame 2 is in an inverted "T" shape, and the frame 2 is rotatably connected to the adjustment module 102 through the rotating shaft 4. A first through-hole 201 is provided on the frame 2, and the first through-hole 201 can be optionally aligned with the first positioning hole 1023 and locked by a fastener; the fastener can be a conventional structure such as a pin shaft and a pin.

[0030] During adjustment, remove the fastener, rotate the frame 2 to align the first through-hole 201 with the other first positioning hole 1023, and then insert the fastener through the first through-hole 201 and into the first positioning hole 1023 to lock it. In this way, on the one hand, the wrap angle between the cable and the rolling body 3 can be adjusted; on the other hand, the height of the rolling body 3 can be adjusted.

[0031] As a preferred solution, the frame 2 is configured to be rotatable and lockable around the central axis of the fixed module 101. For example, Figure 2 As shown, a cylinder is fixed on the bottom of the bottom plate 1021, and at least two second through holes 1024 are provided on the side of the cylinder; Figure 6 As shown, the fixing module 101 is provided with a column 5, which can be inserted into the cylinder and the two are coaxial. The column 5 is provided with a second positioning hole 501, which can be optionally aligned with the second through-hole 1024. When the two are aligned, the fastener is inserted through the second through-hole 1024 and into the second positioning hole 501 to lock the adjustment module 102 with the fixing module 101, thereby achieving the locking of the frame 2 and the base 1.

[0032] When adjusting, first remove the fastener, and then use external force to drive the frame 2 to rotate around the axis of the steel needle until the second through hole 1024 is aligned with the other second positioning hole 501, and then insert the fastener through the second through hole 1024 and into the second positioning hole 501 to complete the locking; the locking is stable and the structure is simple.

[0033] In addition, by rotating the frame 2 around the base 1 to adjust the position and adjusting the angle between the frame 2 and the base 1, the adjustment range of the rolling body 3 can be expanded to adapt to different position and angle requirements, thereby improving the versatility of the wiring mechanism.
