Embodiment 1

[0060] Such as figure 1 The illustrated steering device for tension pay-off construction includes a truss 1 in which a trolley frame 2 is provided, a trolley 3 is provided in the trolley frame 2, and the first end of the trolley frame 2 passes through the first The rope 10 is connected to the truss 1, and the second end of the trolley frame 2 is connected to the truss 1 through a second rope 11, and the position of the connection point of the second rope 11 on the truss 1 is adjustable.

[0061] In some embodiments, the truss includes three masts, the tops of the three masts are fixedly connected, and the bottoms of the three masts form an equilateral triangle. The structure realizes lightweight design on the basis of structural stability and reduces the transportation load of mountainous terrain.

[0062] In some embodiments, a sliding rail may be provided on the truss, and a lifting ring is provided on the sliding block of the sliding rail. The second rope passes through the lift...

Embodiment 2

[0066] Such as figure 1 with figure 2 As shown, on the basis of Embodiment 1, the lengths of the first rope 10 and the second rope 11 are adjusted by a hoist. Wherein, the first rope 10 is connected with a fixed hoist 4, which is fixedly installed on the truss 1; a bearing frame 8 is provided on the truss 1, and a sliding block 6 is slidably arranged on the bearing frame 8. 6 is connected with a mobile hoist 5 through a second rope 11, the mobile hoist 5 is arranged on the second end of the trolley frame 2; the bearing frame 8 is provided with a ball screw 7, and the slider 6 is mounted on the ball On the nut of the screw 7.

[0067] The above arrangement makes it possible to adjust the pitch angle of the pulley even when the first rope or the second rope cannot be adjusted, to ensure the normal operation of the steering, and the reliability of the steering device is higher.

[0068] In some embodiments, two adjacent masts are connected at both ends of the carrying frame 8 to imp...

Embodiment 3

[0070] Such as figure 1 with figure 2 As shown, the steering device for tension pay-off construction includes a truss 1 in which a trolley frame 2 is provided, and a trolley 3 is provided in the trolley frame 2, and one end of the trolley frame 2 passes through the first The rope 10 is connected with a fixed hoist 4, the fixed hoist 4 is fixedly installed on the truss 1, and the other end of the trolley frame 2 is provided with a mobile hoist 5, the mobile hoist 5 is connected with a slider 6 through a second rope 11, and the slider 6 The position on the truss 1 can be adjusted; the truss 1 is provided with a bearing frame 8, the bearing frame 8 is provided with a ball screw 7 and a motor 12, and a slider 6 is mounted on the nut of the ball screw 7, the The output shaft of the motor 12 is connected to the screw of the ball screw 7; it also includes a binocular stereo camera 9 and a processor, and the processor is electrically connected with the binocular stereo camera 9, the fi...

Abstract

The invention discloses a steering device for tension pay-off construction. The device comprises a truss, and a tackle frame is arranged in the truss; a tackle is arranged in the tackle frame, whereinthe first end of the tackle frame is connected to the truss through a first rope, the second end of the tackle frame is connected to the truss through a second rope, and the position of a connectingpoint of the second rope on the truss is adjustable. Through the adjustment of the position of the connecting point of the second rope and the truss, the course angle of the tackle can be adjusted onthe basis of adjusting the pitch angle of the tackle; when the angle deviation between the cable and a tackle chute is increased and the pressure of the cable on the tackle is too large, the directionof pressure can be quickly changed by adjusting the direction angle, the damage of the cable to the tackle is reduced, and meanwhile, the tackle can be quickly and accurately adjusted in cooperationwith pitch angle adjustment, so that the angle between the sliding groove and the cable is quickly reduced to a safety range, the damage to the guide rope and the tackle is avoided, the potential safety hazards are eliminated, and the safety of the steering process is improved.

Description

Technical field [0001] The invention relates to the field of tension pay-off construction, in particular to a steering device and a steering adjustment method for tension pay-off construction. Background technique [0002] Most of the large hydropower stations in Southwest China are built in deep mountains and valleys. Accordingly, more and more transmission lines are being built in the mountains and ridges. [0003] Tension pay-off is a method of erection and installation in the whole process of erecting the wire to maintain a certain tension and leave the ground in an overhead state. As the most important process in the traditional construction method of overhead transmission line construction, tension pay-off construction often encounters restrictions due to the terrain height difference, the length of the pay-off section and the number of times the conductor passes the pulley. The tension field is selected in the direction of the line Very difficult: either the pay-off section...
