[0025] Referring toFigures 1 to 4 and Figure 7 As shown in FIG. 1, the traction rope 17 passes through the transverse positioning plate 11, and the transverse positioning plate 11 is provided with a longitudinal through hole 20, and the traction rope 17 passes through the longitudinal through hole 20. A guide wheel should be arranged at the upper end of the longitudinal through hole 20, which cooperates with the traction rope 17 to enable the compression return spring 14 to form a compressed state during the passing of the traction plate, and then the sliding arm 13 is reset downward under the action of the restoring force of the compression return spring 14.

After the traction plate passes between the lower end of the conductive arm 4 and the pulley 3, the wire is located in the notch 21 of the turnover arm 18 due to the reset and turnover of the turnover arm 18. Figures 2 to 7 ​​As shown, in particular, the locking assembly includes a pullback rod 23 connected to the sliding arm 13, a pullback guide hole 24 is arranged on the transverse positioning plate 11, the pullback rod 23 passes through the pullback guide hole 24, the number of the pullback rod 23 is at least two, the two pullback rods 23 are connected by a pressing strip 25, the pressing strip 25 is connected to the end of the pullback rod 23, at this time, the pressing strip 25 is located above the transverse positioning plate 11, in the process of vertical movement of the sliding arm 13, the pressing strip 25 can be driven to move longitudinally, when the lower end of the conductive brush 5 abuts against the wheel groove of the pulley 3, the pressing strip 25 contacts the transverse positioning plate 11, at this time, the pressing strip 25 can press on the traction rope 17.

[0029] In order to facilitate the adjustment of the position of the pressing strip 25, a threaded section is arranged on the pullback rod 23, and a tray 26 and a locking nut 27 are screwed through the threaded section, the tray 26 is located above the pressing strip 25, and the locking nut 27 is located below the pressing strip 25, the tray 26 is used to adjust the position of the pressing strip 25, and the locking nut 27 is used to lock the pressing strip 25, so that the pressing strip 25 remains at the position, a recess is arranged on the transverse positioning plate 11, when the pressing strip 25 contacts the transverse positioning plate 11, the tray 26 can be located in the recess, so as to ensure that the traction rope 17 can be clamped in cooperation with the transverse positioning plate 11; The above-mentioned lifting and pushing component 22 has a telescopic structure, the lifting and pushing component 22 is installed on the transverse positioning plate 11 or the hanging seat 1, the output end of the lifting and pushing component 22 is butted with a guide wheel 29 through a distribution frame 28, the lifting and pushing component 22 can be selected as an electric push cylinder, the lifting and pushing component 22 is vertically arranged, and the traction rope 17 passes above the guide wheel 29 and is then turned downward and connected with the traction frame 15, that is, the guide wheel 29 is located below the traction rope 17, when the lifting and pushing component 22 is elongated, the guide wheel 29 can be moved upward, at this time, an acting force is applied to the traction rope 17, since the traction rope 17 is clamped by the pressing strip 25 and the transverse positioning plate 11, after the lifting and pushing component 22 is elongated, the traction frame 15 can be turned over, in the process of turning over of the traction frame 15 at this time, the horizontal height of the lower end of the turning arm 18 is lowered, and the horizontal height of the upper end of the turning arm 18 is raised, finally, the notch 21 at the lower end of the turning arm 18 contacts the wire, and the turning arm 18 applies pressure to the wire, at this time, there is a friction force between the turning arm 18 and the wire, which hinders the movement of the wire, so that the pay-off trolley can be offset by a large amplitude.

[0030] The push-up part 22 is connected with a control switch, which is installed in a recess on the horizontal positioning plate 11. When the pressing strip 25 contacts the horizontal positioning plate 11, the tray 26 contacts the control switch, which promotes the operation of the push-up part 22. When the tray 26 is separated from the control switch, the push-up part 22 starts to retract. In order to increase the stability of the connection between the pressing plate and the horizontal positioning plate 11, a cylindrical protrusion 30 can be arranged on the pressing plate, which extends downward. At least two strip-shaped grooves 31 are arranged on the cylindrical protrusion 30. Meanwhile, an insertion groove 32 is arranged on the horizontal positioning plate 11. After the pressing plate contacts the horizontal positioning plate 11, the cylindrical protrusion 30 will be fitted in the insertion groove 32. The strip-shaped grooves 31 on the cylindrical protrusion 30 are hinged with a clamping strip 33. Meanwhile, a matching groove 34 is arranged in the insertion groove 32, in which a magnetic attraction piece is arranged. The magnetic attraction piece can move the clamping strip 33 outward by magnetic attraction. At this time, a clamping structure is formed, and the pressing plate is not easy to separate from the horizontal positioning plate 11. In order to make the pressing strip 25 move away from the horizontal positioning plate 11, the upper end of the cylindrical protrusion 30 is provided with a center rod 35 and a positioning protruding head 36. A positioning groove is arranged on the bottom surface of the pressing plate. When the positioning protruding head 36 is fitted in the positioning groove, the cylindrical protrusion 30 cannot rotate. The center rod 35 passes through the pressing strip 25. A top disc 37 is arranged on the center rod 35. A return spring 38 is further sleeved on the center rod 35. The return spring 38 generates a restoring force after compression, which can exert pressure on the center rod 35 to make the center rod 35 move downward, thereby driving the cylindrical protrusion 30 to move downward, so that the positioning protruding head 36 is separated from the positioning groove, and then the cylindrical protrusion 30 can be rotated. During the downward movement of the center rod 35, the clamping strip 33 starts to reset in the strip-shaped groove 31. When the pressing strip 25 is separated from the horizontal positioning plate 11, the center rod 35 controls the downward movement of the cylindrical protrusion 30, and then the center rod 35 is screwed, so that the cylindrical protrusion 30 starts to rotate. During this process, the clamping strip 33 is separated from the matching groove 34 and resets in the strip-shaped groove 31. At this time, the pressing strip 25 can be lifted upward, thereby facilitating the replacement of the docking arm 7.
