Description

Technical Field

[0001] The present application relates to the technical field of wire-laying pulleys, and more specifically to a grounding device for a wire-laying pulley. Background Art

[0002] The wire-laying pulley is a special equipment used to erect and lay out construction conductors during the construction of power lines. When the construction conductors are parallel to or cross other energized lines, or when one circuit in a double-circuit power line is energized while the other circuit is shut down for construction, electromagnetic induction current will be generated on the construction conductors. If this induced current cannot be released in time, it will be transmitted to the tensioners and traction machines at both ends of the construction line, affecting the operators and construction equipment. The function of the grounding device is to guide this part of the induced current to the grounding device.

[0003] The patent document (CN202333705U) discloses a wire-paying pulley, including a pulley frame, a bracket, a wire-paying pulley, a conductive wheel, a grounding wire and several unfolding wires. One end of the bracket is hinged on the pulley frame, the wire-paying pulley is rotatably mounted on the pulley frame, the conductive wheel is rotatably mounted on the bracket, and one end of the grounding wire is connected to the bracket to realize the conduction of the induced current to the ground. It should be noted that the conductive wheel corresponds one-to-one with the wire-paying pulley, and the wheel widths are the same, and the gaps between the wheel pieces are equal, ensuring that each unfolding wire passes through a corresponding conductive wheel while passing through one wire-paying pulley. However, when the number of wire-paying pulleys is large, since the number of conductive wheels corresponds one-to-one, it is inconvenient to disassemble and assemble the guide wheels one by one, and the guide wheels need to be disassembled and assembled one by one.

[0004] Therefore, there is a need to provide a grounding device for a line-laying pulley with a simpler structure and more convenient assembly and disassembly. Utility Model Content

[0030] refer to Figures 1 to 4 According to a preferred embodiment of the present invention, a grounding device for a line-paying pulley includes a frame assembly 10, a plurality of line-paying pulleys 20 and a grounding assembly 30.

[0031] Specifically, if Figure 1 and Figure 2 As shown, the frame assembly 10 includes two side frames 101, each of the pay-off pulleys 20 is located between the two side frames 101 and is rotatably mounted on the two side frames 101, the grounding assembly 30 includes two swing arms 301, a grounding roller 302 and a grounding wire group 303, and each of the side frames 101 is rotatably mounted with a swing arm 301, both ends of the grounding roller 302 are rotatably connected to the two swing arms 301 respectively, and one end of the grounding wire group 303 is connected to the side frame 101.

[0032] It should be noted that by providing a cylindrical grounding roller 302, the sidewall of which is an optical axis surface, a grounding roller 302 is provided corresponding to each pay-off pulley 20. The wires drawn from each pay-off pulley 20 are all wound around and pass through the grounding roller 302, and the induced current on each wire is transmitted to the swing arm 301 and the side frame 101 through the grounding roller 302, and then conducted to the ground from the grounding winding. It is obvious that compared to the prior art method of providing a conductive wheel with an annular groove and arranging the conductive wheel to correspond one-to-one with the pay-off pulley 20, the embodiment of the present application has the advantages of a simpler structure and more convenient assembly and disassembly.

[0033] Furthermore, to ensure that the wire drawn from each pay-off pulley 20 can be wound around and passed through the grounding roller 302, the length of the grounding roller 302 is greater than the distance between the two side frames 101. More specifically, the swing arm 301 is located in the middle of the width direction of the corresponding side frame 101, and the projections of both ends of the grounding roller 302 overlap with the side frame 101.

[0034] Furthermore, in order to realize the installation of the ground wire group 303 on the side frame 101, as shown in FIG. Figure 1 As shown, each of the side frames 101 has two mounting holes 1011 , and the two mounting holes 1011 are respectively located on both sides of the grounding roller 302 , and one end of the grounding wire group 303 is bolted to one of the mounting holes 1011 on the side frame 101 .

[0035] More specifically, if Figure 1 As shown, the grounding wire group 303 includes a wire portion 3031 and two connecting portions 3032.

[0040] In addition, since the overall width of the multiple pay-out pulleys 20 will change accordingly when the number of the pay-out pulleys 20 increases or decreases, in order to improve the versatility of the hanging beam 102, in an embodiment of the present application, the hanging beam 102 has several groups of symmetrical holes 1022 arranged at intervals on one side close to the side frame 101, and the two side frames 101 are respectively connected to the two symmetrical holes 1022 in one group with movable pins.

[0041] In addition, if Figure 2 As shown, each side frame 101 has a U-shaped groove 1013 on one side close to the hanging beam 102 . The U-shaped groove 1013 is located in the middle section of the side frame 101 , and the hanging beam 102 extends into the U-shaped groove 1013 .

[0042] Furthermore, in order to increase the stability of the side frame 101, as Figure 1 As shown, the frame assembly 10 also includes a connecting rod 103, which is located at one end of the two side frames 101 away from the suspension beam 102, and the two ends of the connecting rod 103 are respectively connected to the two side frames 101, and the connection method includes but is not limited to bolt connection.

[0043] Furthermore, in order to reduce the overall weight of the line-releasing block, as Figure 2 As shown, each of the pay-off pulleys 20 has a plurality of weight-reducing holes 201 .

[0044] In summary, the grounding device of the wire-paying pulley based on the embodiment of the present application is explained, which provides the grounding device of the wire-paying pulley with advantages such as simpler structure and more convenient disassembly and assembly.
