When retrieving the line, simply apply a pushing force to the bent protrusion with the cable to rotate the opening baffle, creating space for line retrieval. The angle of the hook can be adjusted by rotating the rotary wheel, making it suitable for jumper hanging at different inclination angles.

Description

Technical Field

[0001] This utility model relates to the field of substation line installation technology, and in particular to a rotary locking mechanism and a convenient rope hanging device. Background Technology

[0002] In the pre-testing of power plant or outdoor substation lines, the grounding wire plays a crucial role. It can conduct residual charge and nearby induced charge of the line into the ground, prevent the formation of a three-phase short circuit current when the opposite side is accidentally energized, and enable the switch protection to quickly disconnect the switch, avoid electric shock to personnel, and ensure the personal safety of the staff.

[0003] Existing grounding wire hooks have a fixed structure and cannot accommodate jumpers at different tilt angles, especially when the jumpers for line surge arresters are nearly vertical. During pre-testing, traditional grounding wire hooks are prone to falling off or being damaged, leading to wiring failures and posing safety hazards. Conventional handheld hook extension rods do not have angle adjustment capabilities, and even if the hook can accommodate more angles, there are still many inconveniences in operation.

[0004] Therefore, there is a need for a rotary locking mechanism and winding device that can effectively prevent the grounding hook from falling off even when the jumper is in a loose state, and that can adjust the angle of the grounding hook to make it suitable for jumpers with different tilt angles to meet the needs of the current environment. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that traditional grounding hooks in the existing environment are prone to falling off or being damaged when the angle is not appropriate, and the installation is not reliable enough.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] The accommodating component includes an arc plate and an adjustment cavity fixedly formed on the inner wall of the arc plate;

[0009] The locking assembly includes a limiting toothed ring fixedly disposed on one side of the inner wall of the adjusting cavity, an opening baffle disposed on the inner ring of the limiting toothed ring, and a positioning member elastically rotatably disposed on the side wall of the opening baffle.

[0010] In a preferred embodiment of the rotary locking mechanism of this utility model, the inner wall of the limiting tooth ring includes deep teeth and shallow teeth, and the deep teeth and shallow teeth are arranged in an alternating ring array.

[0011] In a preferred embodiment of the rotary locking mechanism of this utility model, a connecting column is fixedly provided at the bottom of the opening baffle, and a mating disc extends from one side of the connecting column, the mating disc being located within the inner ring of the limiting toothed ring.

[0012] In a preferred embodiment of the rotary locking mechanism of this utility model, an adjustment groove is fixedly formed on the side wall of the mating disc, an elastic torsion bar is provided on the inner wall of the adjustment groove, and an unlocking rod is provided at the bottom of the mating disc, with the end of the unlocking rod penetrating through the adjustment cavity.

[0013] In a preferred embodiment of the rotary locking mechanism of this utility model, the elastic torsion bar is fixedly connected to the positioning member, and the outer side of the positioning member cooperates with the limiting toothed ring.

[0014] In a preferred embodiment of the rotary locking mechanism of this utility model, a limiting slot is fixedly opened on the outer wall of the connecting column, a push rod is fixedly connected to the limiting slot, and a bent protrusion is provided at the end of the push rod.

[0015] In a preferred embodiment of the rotary locking mechanism of this utility model, an extension groove is formed on the inner wall of the arc plate, the extension groove is connected to the adjustment cavity, and the bent protrusion passes through the extension groove and is located on the inner side of the arc plate.

[0016] The beneficial effects of the rotary locking mechanism in this utility model are as follows: when the wire is hung, the opening is automatically locked, and even if the jumper is in a loose state, it can effectively prevent the grounding wire hook from falling off. When taking the wire, you only need to use the cable to apply a pushing force to the bending protrusion, drive the opening baffle to rotate, and leave space to take the wire.

[0017] Given that the grounding wire hook structure is fixed in the existing environment, it cannot adapt to jumpers with different tilt angles, especially when the jumper of the line arrester is close to vertical.

[0018] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0019] The adjustment assembly includes a receiving plate located below the arc plate, a rotary wheel rotatably mounted on the receiving plate, and a mating platform fixed to one side of the receiving plate.

[0020] In a preferred embodiment of the winding device of this utility model, the bottom of the mating platform is inserted into the inner wall of the limiting rod, the side wall of the limiting rod is connected to a bolt, and the other end of the bolt is connected to a pin.

[0021] In a preferred embodiment of the winding device of this utility model, an insertion hole is fixedly opened on the side wall of the platform, and the insertion hole is slidably engaged with the pin.

[0022] The beneficial effects of the convenient rope hanging device in this utility model are: by adjusting the rotation of the rotary wheel, the angle of the hook can be adapted to suit the rope hanging work at different tilt angles. Attached Figure Description

[0034] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0035] Example 1

[0036] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a rotary locking mechanism.

[0037] The receiving component 1 is used to receive and hang the cable. The shape of the arc plate 11 itself is designed to resemble the appearance and angle of a hook, which facilitates the placement of the cable. The inner wall of the arc plate 11 is hollowed out to provide an adjustment cavity 12, which is used to ensure the placement and stable operation of the locking component 2.

[0038] A limiting toothed ring 21 is fixedly installed on one side of the inner wall of the adjusting cavity 12. The teeth of the limiting toothed ring 21 are all located in its own inner ring. An opening baffle 22 is also rotatably installed in the inner ring of the limiting toothed ring 21. The opening baffle 22 itself cannot cooperate with the teeth of the limiting toothed ring 21, but a positioning member 23 is elastically rotatably installed on the side wall of the opening baffle 22. The tip of the positioning member 23 engages with the teeth of the limiting toothed ring 21.

[0039] The upper structure of the opening baffle 22 extends to form a corresponding baffle structure, extending out of the adjustment cavity 12 and located inside the arc plate 11, which can block the cable to be hung. When the cable needs to be hung and installed, the worker only needs to align the arc plate 11 with the cable. As the cable enters, it pushes the opening baffle 22 to rotate. The opening baffle 22 causes the positioning member 23 to rotate accordingly. After the tip of the positioning member 23 rotates appropriately, it can make room for the cable to enter.

[0040] Once the cable is fully inside the arc plate 11, even if it becomes loose, the cable cannot push the opening baffle 22 in the opposite direction. The tip of the positioning member 23 cannot move in the opposite direction along the teeth of the inner ring of the limiting tooth ring 21, and will be restricted from rotating in the opposite direction. Therefore, the opening baffle 22 can effectively realize the safe placement and storage of the cable and prevent it from falling off.

[0041] Example 2

[0042] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that...

[0043] The inner wall of the limiting tooth ring 21 includes deep teeth 211 and shallow teeth 212, which are arranged in an alternating circular array. In the default state, the tip of the positioning member 23 in the opening baffle 22 contacts and engages with the deep teeth 211. A connecting post 24 is fixedly provided at the bottom of the opening baffle 22, and a mating disc 241 extends from one side of the connecting post 24. The mating disc 241 is located in the inner ring of the limiting tooth ring 21 and can engage with the limiting tooth ring 21 in subsequent transmission. An unlocking rod 2413 is also provided at the bottom of the mating disc 241. The unlocking rod 2413 passes through the adjustment cavity 12 and is located on the outer wall of the adjustment cavity 12.

[0044] An adjustment groove 2411 is fixedly provided on the side wall of the mating disc 241. There are two adjustment grooves 2411. Each adjustment groove 2411 has an elastic torsion bar 2412 on its inner wall. The two ends of the elastic torsion bar 2412 are connected to the top and bottom of the adjustment groove 2411 respectively. It can rotate moderately on the inner wall of the adjustment groove 2411. During the rotation, the spring built into the torsion bar accumulates the elastic force of the reverse rotation.

[0045] Each elastic torsion bar 2412 is fixedly connected to a positioning member 23. During the rotation of the positioning member 23, the elastic torsion bar 2412 will rotate. The outer tip of the positioning member 23 can cooperate with the limiting tooth ring 21. In the default state, the positioning member 23 and the limiting tooth ring 21 are engaged in the deep tooth 211.

[0046] When it is necessary to hang the cable, the worker first makes the cable contact with the opening baffle 22. After applying an appropriate pushing force, the cable can push the opening baffle 22. The opening baffle 22 can rotate at a certain angle through the cooperation of the positioning part 23 and the deep tooth 211 to make room for the cable to enter the arc plate 11. At this time, the positioning part 23 is still in the deep tooth 211. The appropriate angle rotation will not cause the positioning part 23 to slide out of the deep tooth 211.

[0047] A limiting slot 242 is fixedly opened on the outer wall of the connecting column 24. A push rod 2421 is fixedly connected in the limiting slot 242. The push rod 2421 is also located in the adjustment cavity 12. A bent protrusion 2422 is also fixedly installed at the end of the push rod 2421. An extension slot 111 is opened on the inner wall of the arc plate 11. The extension slot 111 connects the adjustment cavity 12 and the arc plate 11.

[0048] The bending protrusion 2422 passes through the extension groove 111 and is located inside the arc plate 11. When it is necessary to take the cable, the operator only needs to operate the device to make the cable contact the bending protrusion 2422. The bending protrusion 2422 has a beveled shape. The cable can drive the bending protrusion 2422 and the push rod 2421 and the connecting post 24 to rotate more significantly through contact with the beveled surface.

[0049] A large rotation allows the positioning component 23 to slide out of the deep tooth 211 and into the shallow tooth 212. The outer tip of the positioning component 23 cannot move in the opposite direction, so it is stuck by the arrangement of the deep tooth 211 and the shallow tooth 212, ensuring that the opening baffle 22 cannot rotate, thus leaving space for the cable to be removed. After the entire cable removal work is completed, the operator only needs to operate the unlocking lever 2413 to make the positioning component 23 follow the movement of the mating disc 241 and displace the limiting tooth ring 21. At this time, the positioning component 23 returns to its original position under the action of the elastic torsion bar 2412. The unlocking lever 2413 rotates in the opposite direction, causing the mating disc 241 to return to its original position and then be pulled outward, so that the positioning component 23 can return to the initial position of the deep tooth 211.

[0050] Example 3

[0051] Reference Figures 1-7 This is the third embodiment of the present invention, which adds a winding device based on the above embodiments.

[0052] The adjustment component 3 is used to adjust the bending angle of the rotating locking mechanism at the top of the entire device. The receiving plate 31 is located below the arc plate 11. A mating platform 33 is connected to one side of the receiving plate 31, and a corresponding insertion end is provided below the mating platform 33.

[0053] The limiting rod 34 is located below the mating platform 33. The insertion end at the bottom of the mating platform 33 can be inserted into the inner wall of the limiting rod 34, realizing the insertion connection between the mating platform 33 and the limiting rod 34. A rotary wheel 32 is rotatably arranged at the center of the receiving plate 31. The other end of the rotary wheel 32 is fixedly connected to the arc plate 11. A toothed arc plate that can cooperate with the rotary wheel 32 is also provided on one side of the mating platform 33 to ensure smoother operation of the rotary wheel 32.

[0054] The rotation of the rotary wheel 32 and the receiving plate 31 can drive the rotation locking mechanism at the top of the entire device to rotate and change angles. The side wall of the limiting rod 34 is connected to a bolt 341, and the other end of the bolt 341 can be fixedly connected to a pin 3411 through a flexible wire, chain or other structure.

[0055] A socket 331 is fixedly opened on the side wall of the mating platform 33. The size of the socket 331 corresponds to the pin 3411. In the default state, the rotary wheel 32 is already rotating and mating with the receiving plate 31. When the entire device needs to work normally, the operator only needs to insert the mating platform 33 into the limiting rod 34, and after ensuring that the insertion is firm, send the pin 3411 into the socket 331 and ensure that the socket 331 and the pin 3411 are mated and positioned.

[0056] After the socket 331 and the pin 3411 are positioned together, the mating platform 33 and the limiting rod 34 can be firmly connected to ensure that the two will not rotate, slide or loosen. Then the staff can carry out the subsequent wire hanging operation.
