Description

Technical Field

[0002] The traction plate and the corner tower pulley are closely related in the construction and maintenance of power lines and are usually used in combination to ensure the smooth movement and accurate positioning of the conductor or ground wire on the corner tower. Among them, the corner tower pulley is used to move the conductor or ground wire on the corner tower, reducing the friction force through a pulley system to enable the smooth movement of the conductor or ground wire on the corner tower. It is commonly used in the erection and maintenance of high-voltage transmission lines, especially where the line direction changes. The traction plate is used to fix and guide the traction rope to ensure uniform transmission of the traction force and prevent the conductor from being twisted or damaged. When erecting or replacing the conductor, the traction plate is connected to the traction rope, and the conductor moves through the corner tower pulley. The two work together to ensure the smooth passage of the conductor through the corner tower.

[0003] In the prior art, when the traction plate passes through the corner tower pulley, since the pulley is in an inclined state, the traction plate cannot pass through the pulley smoothly. It is necessary to manually adjust the tension of the sub-conductor to make the traction plate tilt at a certain angle to match the pulley and pass through the pulley smoothly. However, adjusting the tension of the sub-conductor is very time-consuming and affects the project progress.

[0075] Specifically, in the embodiment of the present invention, the control component includes a controller 13 and a rotation angle controller 5 which are electrically connected;

[0076] The rotation angle controller 5 is fixed on the outer side of the housing of the torque control box 1, and the controller 13 is fixed inside the housing of the torque control box 1;

[0079] Further, in the embodiment of the present invention, the rotation angle controller 5 includes a rotation angle knob 51 and a scale disk 52;

[0080] The scale disk 52 is fixed on the outer side of the housing of the torque control box 1; the knob shaft of the rotation angle knob 51 passes through the scale disk 52 and extends into the housing of the torque control box 1 and is electrically connected to the controller 13;

[0082] Among them, the rotation angle knob 51 is a component directly operated by construction workers and is used to manually adjust the rotation angle. The inside of the rotation angle knob 51 is usually connected to a shaft or a gear system to transmit the rotation action of construction workers to the internal mechanism of the controller.

[0083] The rotation angle knob 51 is connected to the internal mechanism of the controller through a shaft, gear or worm drive system, converting the rotational movement into an angular change. In the embodiment of the present invention, an encoder knob shaft is adopted. By using the encoder knob shaft, the rotational movement is converted into a digital signal, and an optoelectronic knob encoder or a magnetoelectric knob encoder can be used; the encoder knob shaft is electrically connected to the controller 13.

[0084] The scale disk 52 is used to display the numerical value or position of the current rotation angle, helping the construction personnel to accurately control the rotation angle.

In actual applications, the balance requirements can be met by adding or reducing the number of balance blocks.

[0092] Specifically, after tilting, the traction plate 6 in the embodiments of the present invention is parallel to the axis of the pulley 9 in the corner tower pulley block. Among them, the axis of the output end of the actuating component and the symmetry axis of the traction plate 6 are in the same vertical plane perpendicular to the traction plate 6. After tilting, the balance weight 3 generates a torque by its own gravity, causing the traction plate 6 to be parallel to the axis of the pulley 9 after tilting, so as to maintain balance with the corner tower pulley block.

[0093] Specifically, in the embodiments of the present invention, the torque control box 1 is fixedly installed on the traction plate 6 by a detachable connection. When the traction plate is performing wire laying operations and passing through the corner tower, the torque control box 1 can be installed on the traction plate 6. By fixing the torque control box 1 to the traction plate 6 in a detachable connection manner, it is convenient to improve the existing traction plate 6 without the need to manufacture new traction devices additionally, saving construction costs.

[0094] Embodiment 2

[0095] In the embodiments of the present invention, taking the "one-pull-two" traction plate passing through the corner tower pulley block as an example, a traction plate device suitable for the corner tower provided by the present invention is used for wire laying operations, specifically for the operation of the traction plate of the transmission line passing through the pulley block. It includes a traction plate 6 and a torque device; the torque device is fixedly installed on the traction plate 6. The torque device can assist in adjusting the angle of the traction plate when the traction plate passes through the corner tower pulley block, enabling the traction plate to pass through the corner tower pulley block more smoothly. As Figure 3 shown, the torque device includes a torque control box 1, a torque connecting piece 2 and a balance weight 3. The balance weight 3 is rotated through the torque control box 1. The torque control box 1 on the traction plate 6 assists the traction plate to pass through the corner tower pulley block smoothly by controlling the left and right swing angles of the balance weight 3.

[0096] As Figure 5 shown, the torque control box 1 includes: a battery 11, a connecting wire 12, a controller 13, a rotating motor 14, a driver 15, a power switch 4 and a rotation angle controller 5. In this embodiment, the rotating motor 14 is a stepping motor, and the following description will be based on the stepping motor.

[0097] Among them, the battery 11, the connecting wire 12, the controller 13, the stepping motor, and the driver 15 are installed inside the housing of the torque control box 1, and the power switch 4 and the rotation angle controller 5 are installed outside the housing of the torque control box 1.

[0098] The driver 15 is respectively connected to the battery 11, the controller 13 and the stepping motor through the connecting wire 12; the driver 15 receives the control signal sent by the controller 13 and drives the stepping motor to rotate. The battery 11 is connected to the stepping motor through the driver 15 to supply electrical energy to the stepping motor, and the controller 13 controls the stepping motor to rotate to the required angle. As Figure 4 shown, the rotation angle controller 5 is connected to the controller 13, and the power switch 4 is connected to the driver 15 to control the start and stop of the stepping motor.

[0099] The controller 13 is the core component of the torque control box 1, responsible for receiving the input signal of the rotation angle controller 5 and controlling the output of the driver 15. The controller 13 is connected to the stepping motor through the driver 15, and the rotation angle controller realizes the rotation control of the balance weight through the stepping motor controller. When preparing for the wire laying operation, according to the inclination angle of the pulley 9, the controller 13 controls the stepping motor to rotate to drive the balance weight 3 to incline to generate torque by gravity, and the auxiliary traction plate 6 passes through the pulley 9 in the corner tower pulley.

[0100] As Figure 6 shown, the rotation angle controller 5 includes a rotation angle knob 51 and a scale disk 52; among them, the scale disk 52 is marked with angle values of 0°, 22.5°, 45°, 67.5°.

[0101] The specific process of rotating the rotation angle controller 5 in the embodiment of the present invention is as follows:

[0102] The construction worker starts the torque control box 1 through the power switch 4, and the driver 15 starts to supply power.

[0103] The construction worker rotates the rotation angle knob 51 in the rotation angle controller 5, inputs the target angle value based on the scale disk 52, and generates a corresponding angle signal through the knob shaft.

[0104] The rotation angle controller 5 transmits the angle signal to the controller 13.

[0105] The controller 13 generates an angle control signal for controlling the stepping motor to rotate clockwise or counterclockwise by a corresponding angle according to the received angle signal.

[0106] The driver 15 receives the angle control signal, drives the stepping motor to rotate clockwise or counterclockwise by a corresponding angle, drives the balance weight 3 to incline to the left or right to a corresponding angle to generate torque by the gravity of the balance weight 3, so that the traction plate 6 inclines to a corresponding angle to be balanced with the corner tower pulley.

[0107] The housing of the torque control box 1 in the embodiment of the present invention is usually made of high-strength metal such as aluminum alloy or engineering plastic, has good impact resistance and corrosion resistance, can be waterproof and dustproof, and is suitable for harsh working environments.

[0108] In the embodiment of the present invention, the torque control box 1 is fixedly connected to the traction plate 6 by bolts, and the installation structure is as follows Figure 9 shown. Among them, the torque control box 1 is fixed at the middle position of the traction plate 6; among them, the stepping motor is fixedly installed on the symmetry axis (left - right symmetry line) of the traction plate 6. By setting the stepping motor on the symmetry axis of the traction plate 6, it can ensure that the balance weight 3 tilts to generate torque by using gravity, and the tilting effects on the left and right ends of the traction plate 6 are the same, which is convenient for controlling the tilting angle.

[0109] As Figures 7 to 9 shown, in the embodiment of the present invention, the stepping motor is connected to the balance weight 3 through the torque connecting member 2 to control the rotation of the balance weight 3.

[0110] One end of the torque connecting member 2 is connected to the output end of the stepping motor, and the other end of the torque connecting member 2 is hinged to the balance weight 3.

[0111] Specifically, as Figures 10 to 11 shown, in the embodiment of the present invention, a first traction connecting member 7 is provided at the top of the traction plate 6; a plurality of second traction connecting members 8 are provided at the bottom of the traction plate 6. In the embodiment of the present invention, the number of the second traction connecting members 8 is 2.

[0112] The first traction connecting member 7 connects the traction rope, and the traction rope connects the traction device; the second traction connecting member 8 connects the wire, which can reduce the contact resistance with the pulley groove when passing through the pulley.

[0113] When performing the wire laying operation of the angle tower, one end of the traction rope passing through the pulley 9 is connected to the traction device, and the other end of the traction rope is connected to the first traction connecting member 7 on the traction plate 6. The second traction connecting member 8 connects the wire to be laid.

[0114] The traction device pulls the traction rope, and the traction rope drives the traction plate 6 to pass above the pulley 9. Because the pulley 9 will tilt during the wire laying operation of the angle tower, by rotating the stepping motor in the torque control box 1, the angle required for the balance weight 3 to rotate in one direction is controlled, so that the traction plate 6 tilts in the required direction by using the influence of the self - gravity of the balance weight 3, so that the traction plate 6 and the pulley 9 are in a balanced state. The first traction connecting member 7 and the second traction connecting member 8 can be stuck in the pulley groove of the pulley 9 and move along the pulley groove. The edge of the pulley groove restricts the traction plate 6 from moving laterally, effectively preventing the wire from coming out of the groove when the traction plate 6 passes through the pulley. This enables the traction plate 6 to pass through the pulley 9 in the angle tower pulley more smoothly, ensuring that the traction device will not have a wire - off - groove phenomenon when passing through the pulley.

[0115] As Figures 12 to 13As shown, when preparing for the wire laying operation, the torque control box 1 is installed on the traction plate 6. The stepping motor in the torque control box 1 is connected to the balance weight 3 through the torque connecting piece 2.

[0116] As Figure 14 shown, when the pulley block tilts to the left, according to the actual tilting angle of the pulley block, rotate the angle knob clockwise to the specified scale, control the balance weight 3 to rotate to the corresponding angle, and assist the traction plate to pass smoothly through the pulley 9 in the corner tower pulley block.

[0117] As Figure 15 shown, when the pulley block tilts to the right, according to the actual tilting angle of the pulley block, rotate the angle knob counterclockwise to the specified scale, control the balance weight 3 to rotate to the corresponding angle, and assist the traction plate to pass smoothly through the pulley 9 in the corner tower pulley block.

[0118] Embodiment 3

[0119] Based on the same inventive concept, the present invention also provides a traction wire laying system, including: a traction device as in Embodiment 1 and a corner tower pulley block fixed on the corner tower;

[0120] The traction rope connected to the traction plate 6 in the traction device passes through the corner tower pulley block, the traction rope pulls the traction plate 6 through the corner tower pulley block, the traction plate 6 drives the wire through the pulley 9 in the corner tower pulley block, and the wire is crimped in the pulley groove of the pulley 9.

[0121] Specifically, the corner tower pulley block is fixed on the corner tower through the mounting bracket, and the fixing method is fixed by detachable connection, for example: bolt fixing or pin fixing. The mounting bracket includes an L-shaped bracket or a U-shaped bracket.

[0122] Specifically, when the traction device passes through the corner tower pulley block, the traction instrument pulls the traction rope, and the traction rope drives the traction plate 6 to pass above the pulley 9 in the corner tower pulley block. Because the pulley 9 will tilt during the wire laying operation of the corner tower, the control component in the torque control box 1 controls the execution component to rotate clockwise or counterclockwise to drive the balance weight 3 to tilt to the left or to the right to utilize the gravity of the balance weight 3 to generate torque, so that the traction plate 6 and the corner tower pulley block are in a balanced state and remain parallel. After the traction plate 6 passes through the corner tower pulley block, it drives the wire through the pulley 9 in the corner tower pulley block, and the wire is crimped in the pulley groove of the pulley 9, effectively preventing the wire from slipping out of the groove when the traction plate 6 passes through the pulley. Make the traction plate 6 more smoothly pass through the pulley 9 in the corner tower pulley block, and ensure that the traction device will not have a wire slipping out of the groove phenomenon when passing through the pulley block.
