Description

Technical Field

[0001] The invention relates to the field of electric power operation and maintenance, and in particular to a rodless high-voltage grounding wire winding trolley. Background Art

[0002] High-voltage grounding wire is a widely used safety tool in power systems. Poleless high-voltage grounding wire is commonly used in voltage levels of 110kv and above. Compared with pole-mounted high-voltage grounding wire, it has the characteristics of longer length, heavier weight, and thicker grounding wire. It is also impossible to wind the wire around the insulating operating rod like pole-mounted grounding wire, which leads to many problems during winding operation.

[0003] In actual operation, operators usually use manual winding, which generally requires two people to work together, one to pull the wire and the other to wind it. However, for poleless high-voltage grounding wires, due to their own characteristics, manual winding, laying, handling and storage require a lot of physical energy from operators.

[0004] Manual winding is not only troublesome, but also prone to tangling, which will bring inconvenience to the next use of the grounding wire and affect the neatness and appearance of the wire placed in the safety tool cabinet. In addition, there is a risk of heavy objects injuring people during manual operation, and winding is laborious and time-consuming, which indirectly affects the power supply reliability of the power grid. Therefore, a poleless high-voltage grounding wire winding trolley is urgently needed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a rodless high-voltage grounding wire winding trolley with a simple structure, easy operation and use, capable of quickly winding and unwinding the grounding wire, saving a lot of time and energy required for manual winding, improving work efficiency and reducing labor intensity.

[0006] The present invention adopts the following technical solutions: A rodless high-voltage grounding wire winding trolley comprises a frame, a roller is arranged at the bottom of the frame, a winding reel is rotatably arranged on the frame, a locking box is arranged outside the winding reel; a pull rod is arranged on the frame on the side of the winding reel away from the locking box.

[0007] Preferably, the cable winding drum is detachably connected to the frame.

[0008] Preferably, the winding reel is provided with a crank.

[0009] Preferably, a through hole is formed through the side wall of the winding drum corresponding to the locking box.

[0010] Preferably, a positioning bolt for positioning the winding drum is provided on the frame.

[0011] Preferably, the length of the pull rod is adjustable.

[0012] Preferably, a tool box is provided on the frame at the side where the pull rod is located.

[0013] Preferably, the rollers are provided in two groups, which are respectively located at the front and rear sides of the bottom of the frame.

[0014] Preferably, the rollers include a universal wheel located at the front end of the frame and a triangular wheel set located at the rear side of the frame.

[0015] Preferably, the positioning bolt is elastically or threadedly arranged on the frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention can place the grounding end of the rodless high-voltage grounding wire into the locking box, rotate the winding reel clockwise to carry out the wire-winding work, and when releasing the wire, rotate the winding reel counterclockwise to release the wire, and the wire winding and releasing work can be completed. The operation is simple and quick, saving a lot of time and energy required for manual winding and releasing the wire, and effectively improving work efficiency. At the same time, it ensures the safety of operation, avoids safety accidents such as heavy objects injuring people during manual handling and winding, and reduces operational risks; in addition, it also optimizes storage management, making the storage of grounding wires more neat and standardized, easy to manage and find, and also conducive to keeping the workplace clean; the rodless grounding wire is moved and transported by a trolley, and operators no longer need to perform heavy manual winding and handling work, which reduces the physical burden and labor intensity.

[0017] Furthermore, the present invention also improves the winding quality, ensures that the grounding wire is wound evenly and tightly, avoids chaotic winding, and is conducive to rapid unfolding when used next time; standardized winding and storage methods help to protect the performance of the grounding wire and improve its reliability during use; reasonable winding and storage reduce the frequency of the grounding wire needing to be repaired or replaced due to damage, thereby reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be described clearly and completely below with reference to the accompanying drawings and embodiments: like Figure 1 to Figure 2As shown, a rodless high-voltage grounding wire winding trolley of the present invention comprises a frame 1, and a roller 2 is arranged at the bottom of the frame 1 to facilitate the movement of the frame 1, wherein the roller 2 is arranged in two groups, respectively located at the front and rear sides of the bottom of the frame 1; preferably, the universal wheel located at the front end of the frame 1 has a self-locking structure, which is convenient for positioning during work; the triangular wheel group is located at the rear side of the frame 1, and the triangular wheel group is a ladder structure composed of three wheels arranged in a triangle. The triangular wheel group is adapted to various complex roads of the substation, convenient for entering the safety tool room and equipment area, and has a climbing staircase function for the transportation of the rodless high-voltage grounding wire; a winding drum 3 is rotatably arranged on the frame 1, which is used for winding the rodless high-voltage grounding wire, and a locking box 4 is arranged on the outside of the winding drum 3, which is used for placing and storing the grounding end of the rodless high-voltage grounding wire, and promoting the orderly winding of the rodless high-voltage grounding wire on the winding drum 3; a pull rod 5 is arranged on the frame 1 on the side of the winding drum 3 away from the locking box 4, which is convenient for pushing the trolley to move. When winding and reeling in the wire, put the grounding end of the rodless high-voltage grounding wire into the locking box 4, rotate the winding drum 3 clockwise to reel in the wire, and the winding and reeling work can be completed. When winding and unwinding the wire, rotate the winding drum 3 counterclockwise to unwind the wire, and the winding and unwinding work can be completed; the operation is simple and quick, and the work efficiency is effectively improved; at the same time, the rodless high-voltage grounding wire is wound on the winding drum 3 in an orderly manner, avoiding chaotic winding, which is conducive to rapid unfolding when used next time, improving the winding quality, and also helping to protect the performance of the grounding wire, enhancing its reliability during use, and reducing the maintenance cost caused by the damage of the grounding wire due to unreasonable winding.

[0020] Furthermore, the winding drum 3 is detachably connected to the frame 1, so that the winding drum 3 can be removed from the trolley together with the grounding wire and placed in a safety tool cabinet to facilitate the positioning of tools; specifically, a rotating shaft 6 can be rotatably set on the frame 1, and the winding drum 3 can be passed through the rotating shaft 6 and fixed with bolts. When the winding drum 3 needs to be removed, it only needs to remove the bolts. In addition, a crank 7 is also provided at one end of the winding drum 3 located on the outside to facilitate the rotation of the winding drum 3 for the operation of winding and releasing the wire.

[0021] Furthermore, a through hole 8 is formed on the side wall of the winding drum 3 corresponding to the locking box 4, so that the grounding end of the rodless high-voltage grounding wire can pass through the through hole 8 and be placed in the locking box 4 during the wire-winding operation, thereby improving the orderliness of the wire-winding and enhancing the overall neatness of the winding drum 3 after the wire-winding. It also avoids the situation where the grounding wire connected to the grounding end directly passes over the top of the winding drum 3 and enters the locking box 4, and the grounding wire set outside the winding drum 3 accidentally contacts with external objects during rotation, causing damage to the grounding wire.

[0022] Furthermore, the frame 1 is provided with a positioning bolt 9 for positioning the winding drum 3. The positioning bolt 9 is used to position the winding drum 3 after winding is completed to prevent it from rotating due to external force and causing the ground wire to fall out of it. The positioning bolt 9 can be elastically or threadedly arranged on the frame 1. Specifically, the positioning bolt 9 can be threadedly connected to the frame 1. When connected, the positioning bolt 9 is rotated and adjusted during use. The positioning bolt 9 is tightly abutted against the side wall of one end of the winding drum 3 to limit it. The positioning bolt 9 can also be elastically arranged. The positioning bolt 9 is arranged on the frame 1 by a spring. When working, the positioning bolt 9 is pulled open to contact the winding drum 3. After winding is completed, the positioning bolt 9 is released to drive the positioning bolt 9 to reset under the restoring force of the spring to complete the positioning of the winding drum 3.

[0023] Furthermore, in this embodiment, the length of the pull rod 5 is adjustable to meet the needs of workers of different heights. The pull rod 5 can be in the form of a telescopic sleeve, and its length can be freely adjusted. In addition, a tool box 10 is provided on the frame 1 on the side where the pull rod 5 is located, which is used to store the site sign, so as to facilitate the storage and carrying of the site sign.

[0024] When the present invention is used, when winding and reeling in the wire, the grounding end of the rodless high-voltage grounding wire is placed in the locking box 4, and the crank handle 7 is turned clockwise to drive the winding drum 3 to rotate and reel in the wire, and the winding and reeling work can be completed. When winding and releasing the wire, the crank handle 7 is turned counterclockwise to drive the winding drum 3 to rotate and release the wire, and the winding and releasing work can be completed; the operation is simple and fast, and the work efficiency is effectively improved; at the same time, the rodless high-voltage grounding wire is wound on the winding drum 3 in an orderly manner, avoiding chaotic winding, which is conducive to rapid unfolding when used next time, improving the winding quality, and also helping to protect the performance of the grounding wire, enhancing its reliability during use, and reducing the maintenance cost caused by the damage of the grounding wire due to unreasonable winding, and the practicality is strong.
