Description

Technical Field

[0002] The tension wire laying method is a wire laying method widely used in wire laying construction. It uses construction machinery such as traction machines and tension machines to lay out guide wires and ground wires, so that they are off the ground and obstacles in an overhead state during the laying process. Generally, it is necessary to use a traction board to pull the conductor through the wire laying pulley to complete the conductor laying work. Traditional wire laying construction relies on manual observation of the positional relationship between the connector and the wire laying pulley and manual adjustment of related components. Manual observation has visual errors, and the timeliness and accuracy of operation are difficult to guarantee. Not only is it easy for operational errors to cause problems such as conductor jumping and equipment failure, but frequent manual intervention also makes construction efficiency low. At the same time, workers work in dangerous environments such as high altitudes and face high safety risks. In addition, in traditional tension wire laying construction, there is a lack of an adaptive adjustment mechanism for the mechanical structure when the connector passes through the wire laying pulley, which is not convenient for the passage of the connector.

The support wheels 324 support the first pull rope 3226 / the second pull rope 3220, and two linkage members 322 are provided, and the two linkage members 322 are symmetrically arranged.

[0038] The linkage member 322 includes a transmission plate 3221 disposed on the support base 321, a rack 3222 disposed on the transmission plate 3221, a first gear 3223 and a second gear 3224 disposed in the movable slot 312, a winding drum 3225 disposed on the second gear 3224, and a first pull rope 3226 disposed on the winding drum 3225;

[0042] During use, in conjunction with Example 1, the tensioning machine 14 is started, and under the traction action of the traction rope 12, the connector body 13 is pulled toward the line-releasing pulley frame 11, and the motor 211 is started to drive the bidirectional screw rod 212 to rotate, and the two rod sleeves 213 move away from each other. The movable plate 221 drives the first adjustment block 222 to move upward under the action of the two rod sleeves 213, the first U-shaped block 214, the rotating push rod 215 and the second U-shaped block 216, so that the distance between the first adjustment block 222 and the pulley body 316 changes, and the distance becomes larger, which facilitates the passage of the connector body 13;

[0043] When the connector body 13 approaches the pulley body 316, the pulley body 316 is forced to drive the support plate 315 downward, which further changes the distance between the first adjustment block 222 and the slide plate 314 body, and the distance becomes further increased, making it easier for the connector body 13 to pass through.

[0044] When the first pull rope 3226 is wound, the corresponding second adjustment block 342 is pulled away from the pulley body 316, so that the distance between the two second adjustment blocks 342 on the left and the two second adjustment blocks 342 on the right changes, and the distance becomes larger, which is convenient for the connector body 13 to pass through;

[0045] After the connector body 13 passes smoothly through the wire-releasing pulley frame 11, the motor 211 is started, so that the two rod sleeves 213 move closer to each other under the action of the bidirectional screw rod 212, so that the movable plate 221 drives the first adjustment block 222 to move downward and reset on the first U-shaped block 214, the rotating push rod 215 and the second U-shaped block 216, so that the distance between the first adjustment block 222 and the pulley body 316 changes, and the distance becomes smaller, thereby preventing the wire 17 from jumping and reducing the damage caused by friction or position deviation of the wire 17;

[0046] The pulley body 316 loses the force of the connector body 13, and under the action of the first spring 313, it drives the support plate 315, the slide plate 314, the support seat 321 and the transmission plate 3221 to reset upward, and the first gear 3223 and the second gear 3224 drive the winding drum 3225 to reset.

[0050] Specifically, a first inclined surface A is provided on the sliding seat 3229, a second inclined surface B is provided on the extrusion plate 3227, a fixed plate 3228 is fixedly connected to the inner wall of the movable groove 312, four fixed plates 3228 are provided, and the four fixed plates 3228 are symmetrically distributed in pairs, the sliding seat 3229 is slidably connected to the corresponding two fixed plates 3228, the second pull rope 3220 is fixedly connected to the second adjustment block 342 and the sliding seat 3229, the fixed plates 3228 are arranged in a "T" shape, and a third spring C is provided between the two sliding seats 3229;

[0051] During use, in conjunction with Example 2, when the sliding seat 3229 moves downward, the extrusion plate 3227 moves downward along with the sliding seat 3229, and the extrusion plate 3227 applies a downward extrusion force to the sliding seat 3229. The two sliding seats 3229 move closer to each other under the action of the first inclined surface A, the second inclined surface B, and the fixed plate 3228, so that the two second adjustment blocks 342 on the left and the two second adjustment blocks 342 on the right are pulled away from each other by the second pull rope 3220, so that the distance between the two second adjustment blocks 342 on the left and the two second adjustment blocks 342 on the right changes, and the distance becomes larger, which facilitates the passage of the connector body 13.

[0052] When the connector body 13 passes through the wire-releasing pulley frame 11, the pulley body 316 loses the force of the connector body 13, and under the action of the first spring 313, the support plate 315, the slide plate 314, the support seat 321 and the transmission plate 3221 are driven to reset upward, and the sliding seat 3229 loses the squeezing force of the squeezing block, so that the second pull rope 3220 loses the tension, so that the two second adjustment blocks 342 on the left and the two second adjustment blocks 342 on the right are reset under the action of the second spring 343, and the spacing between them changes, and the spacing becomes smaller, preventing the wire 17 from jumping and reducing the damage of the wire 17 caused by friction or position deviation. At the same time, the two sliding seats 3229 are reset under the action of the third spring C and the fixed plate 3228;

[0053] The rest of the structure is the same as that of Example 2

[0054] Example 4

[0055] This embodiment is different from the first embodiment in that it provides a method for stretching and paying out a connector adaptively passing a pulley, which includes: using a stretching machine 14 to make the traction rope 12 pull the connector body 13 and the conductor 17 close to the pay-out pulley frame 11; measuring the distance from the connector body 13 to the pay-out pulley frame 11 by a signal receiver on the connector body 13; the signal receiver transmits the distance signal to a controller on the traction machine in real time; controlling the traction speed of the traction rope 12 by the controller; when the connector body 13 approaches the pay-out pulley frame 11, the adjustment member 21 controls the moving member 22 to move upward; when the connector body 13 approaches the pulley body 316, the pulley member 31 moves downward, so that the distance between the pulley member 31 and the moving member 22 changes; the downward movement of the pulley member 31 triggers the control member 32 to control the change in the distance between the two connecting members 34; the connector body 13 passes through the pay-out pulley frame 11, and the moving member 22, the pulley member 31 and the connecting member 34 are reset;

[0056] Specifically:

[0057] S1. Start the traction machine. Under the traction of the traction rope 12, the wire 17 and the connector body 13 move closer to the pay-off pulley frame 11. The signal receiver measures the distance from the connector body 13 to the pay-off pulley frame 11 and then transmits the signal to the controller through the network. The controller controls the traction speed of the traction machine.

[0058] S2. When the connector body 13 approaches the pay-off pulley frame 11, the traction speed of the traction machine is reduced, and the controller starts the motor 211. The motor 211 drives the bidirectional screw rod 212 to rotate, thereby controlling the rod sleeves 213 at both ends to move to both sides. At the same time, the push rod 215 is rotated to pull the movable plate 221 and the first adjustment block 222 upward, thereby increasing the distance between the first adjustment block 222 and the pulley body 316, so that the connector body 13 can pass through.

[0059] S3: The pulley body 316 is forced to move downward, pushing the slide plate 314 downward through the support plate 315, and then the linkage member 322 pulls the second adjustment block 342 outward, increasing the distance between the two corresponding second adjustment blocks 342, facilitating the passage of the connector body 13;

[0060] S4. After the connector body 13 passes through the pay-off pulley frame 11, the traction machine automatically accelerates traction, thereby improving construction efficiency. At the same time, the controller reverses the motor 211 and pushes the movable plate 221 and the first adjustment block 222 downward by rotating the push rod 215, reducing the distance between the first adjustment block 222 and the pulley body 316, thereby preventing the wire 17 from jumping.

[0061] S5. The force on the pulley body 316 is reduced, and the first spring 313 and the second spring 343 recover their deformation, driving the corresponding two first adjustment blocks 222 to move toward the center through the linkage member 322, further preventing the wire 17 from jumping.

[0062] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
