Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a transmission line tower wire clamp. Background Art

[0002] The disclosure has the publication number CN215580273U and is a wire clamp for stringing cables for power transmission line projects on power transmission line towers. The overall structure of the wire clamp is formed into an I-shape, and an I-shaped part is slidably arranged below a connecting port of the wire clamp, so that a pressure ring arranged above the I-shaped part can cooperate with a mother part to clamp the cable. The device uses a ratchet matching structure and a corresponding spring structure arranged at the bottom to enable the I-shaped part to be reversely locked in a non-extrusion state. During operation, the cable can be directly placed in and pushed. The operation is convenient and quick, and can effectively reduce the hidden dangers of workers working at heights.

[0003] The above-mentioned wire clamp for stringing cables on transmission line towers lacks a shaking mechanism when used outdoors. When it snows outdoors, snow will adhere to the outer wall of the cable. When there is a lot of accumulated snow, the overall weight of the wire will increase, which may cause the cable to break and be damaged. Utility Model Content

[0004] The utility model aims to provide a transmission line tower wire clamp, which can solve the problem that when a lot of snow is accumulated, the weight of the entire wire will increase, which may cause the cable to break and be damaged.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transmission line tower wire clamp, comprising a fixing box, an upper clamp and a driving motor, wherein a mounting plate is fixedly mounted on the top of the fixing box;

[0006] A rotating rod is fixedly mounted on the rotating shaft of the driving motor, and one end of the rotating rod is rotatably mounted on an inner wall of one side of the fixing box;

[0007] A lower clamp is arranged below the upper clamp, and a clamping space is arranged between the upper clamp and the lower clamp.

[0008] Preferably, a cam is fixedly mounted on the outer wall of the rotating rod.

[0009] Preferably, a sliding rod is slidably installed at the bottom of the fixed box, one end of the sliding rod extends to the interior of the fixed box and is fixedly installed with a fixed cross plate, a return spring is fixedly installed at the bottom of the fixed cross plate, the bottom of the return spring is fixedly installed with the inner bottom of the fixed box, and the bottom of the sliding rod is fixedly installed with the top of the upper clamp.

[0010] Preferably, holes are provided inside the upper clamp and the lower clamp, and the upper clamp is provided with a mounting bolt, one end of the mounting bolt passes through the holes on the upper clamp and the lower clamp and extends to the bottom of the lower clamp and is threadedly mounted with a mounting nut.

[0011] Preferably, the bottom of the upper clamp and the top of the lower clamp are both arranged in an arc shape.

[0012] Preferably, the mounting plate is provided with two groups of mounting holes, such an arrangement facilitates the mounting plate to be installed on the pole tower.

[0013] Preferably, the bottom of the cam contacts the top of the fixed transverse plate and is not fixed, so that the fixed transverse plate can be easily moved.

[0014] Compared with the prior art, the beneficial effect of the utility model is that the transmission line pole tower line clamp, through the setting of the driving motor and the rotating rod, can shake the upper clamp and the lower clamp up and down during outdoor use, so that when used in heavy snow weather, the cable can be shaken to remove the snow on the cable surface, avoiding excessive snow accumulation on the cable surface to increase the cable weight and cause damage or breakage of the cable, thereby protecting the cable and reducing the chance of cable damage, and the upper clamp and the lower clamp are three groups, which can fix three groups of cables at the same time, and the snow on the three groups of cables can be cleaned later to increase the practicability of the device.

[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a transmission line tower wire clamp, comprising a fixing box 1, an upper clamp 4 and a driving motor 8, a mounting plate 2 is fixedly installed on the top of the fixing box 1; a rotating rod 9 is fixedly installed on the rotating shaft of the driving motor 8, and one end of the rotating rod 9 is rotatably installed with an inner wall of one side of the fixing box 1; a lower clamp 5 is provided below the upper clamp 4, a clamping space is provided between the upper clamp 4 and the lower clamp 5, and a cam 10 is fixedly installed on the outer wall of the rotating rod 9.

[0022] Furthermore, a sliding rod 3 is slidably installed at the bottom of the fixed box 1, one end of the sliding rod 3 extends to the interior of the fixed box 1 and is fixedly installed with a fixed cross plate 11, and a return spring 12 is fixedly installed at the bottom of the fixed cross plate 11, the bottom of the return spring 12 is fixedly installed to the inner bottom of the fixed box 1, and the bottom of the sliding rod 3 is fixedly installed to the top of the upper clamp 4. This arrangement can make the upper clamp 4 and the lower clamp 5 shake up and down during outdoor use, so that when used in heavy snow, the cable can be shaken and the snow on the surface of the cable can be processed to avoid excessive snow on the surface of the cable, which increases the weight of the cable and causes damage or breakage of the cable, thereby protecting the cable and reducing the chance of cable damage.

[0023] Furthermore, holes are provided inside the upper clamp 4 and the lower clamp 5, and the upper clamp 4 is provided with a mounting bolt 6, one end of the mounting bolt 6 passes through the holes on the upper clamp 4 and the lower clamp 5 and extends to the bottom of the lower clamp 5 and is threadedly installed with a mounting nut 7, the bottom of the upper clamp 4 and the top of the lower clamp 5 are both arranged in an arc shape, and two groups of mounting holes are provided on the mounting plate 2, and the bottom of the cam 10 is in contact with the top of the fixed horizontal plate 11 and is not fixed. This arrangement can fix three groups of cables at the same time, and the snow on the three groups of cables can be cleared later to increase the practicality of the device.

[0024] Working principle: When in use, first install the mounting plate 2 on the pole tower through the mounting hole on the mounting plate 2, then rotate the mounting nut 7 to separate the upper clamp 4 and the lower clamp 5, place the cable at the bottom of the upper clamp 4, and then install the lower clamp 5 with the upper clamp 4 through the mounting nut 7 and the mounting bolt 6, so that the cable can be clamped and fixed. When there is snow on the cable, the control drive motor 8 is started, and the drive motor 8 starts to drive the rotating rod 9 to rotate, and the rotation of the rotating rod 9 drives the cam 10 to rotate. When the cam 10 rotates, the fixed cross plate 11 can move, and the movement of the fixed cross plate 11 drives the sliding rod 3 to move, so that the upper clamp 4 and the lower clamp 5 can be moved downward. When the upper clamp 4 and the lower clamp 5 move downward, the upper clamp 4 and the lower clamp 5 can be rebounded by the reset spring 12, so that the cables on the upper clamp 4 and the lower clamp 5 can be shaken.
