Description

Technical Field

[0001] The utility model relates to the technical field of electric power safety engineering, in particular to a hook-rotatable insulating operating rod. Background Art

[0002] In the field of power engineering, insulating levers are often used to maintain and operate high-voltage power lines and equipment. Workers can use the lever to perform switch operation, line maintenance, equipment installation, etc. without having to directly contact the power equipment, thereby reducing the risk of electric shock. So far, the sleeve-type insulating lever hook used for live working in China is fixed at the head of the insulating lever and cannot be rotated. In the live working lap-link lead, the sleeve-type insulating lever fastening wire clamp bolt is easy to collide with the other two operating lever hooks that fix the wire and the wire clamp when rotating, causing the operator to frequently adjust the position and angle when fastening the bolt, which brings inconvenience and safety hazards to the live working operation. The application number is (201320003814.1) after retrieval, which discloses a hook-rotatable insulating lever, including an insulating lever body, a hook arranged on the insulating lever body, a detachable sleeve head is provided on the top of the insulating lever body, and a detachable sleeve clamp for positioning the detachable sleeve head is provided on the top of the insulating lever body.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved; the above-mentioned disclosed technical solution has major defects: since the hook adopts a sleeve with micro-teeth to cooperate with the rod body, when the sleeve is used, although the hook encounters an obstacle, the rod body can still rotate, but the rotation is blocked, and it is inconvenient for the operator below to apply force. When the sleeve is not used, the fastening effect of the micro-teeth is not good, so the hook is easy to rotate by itself when used, and the hook cannot be accurately controlled. This poses certain safety hazards in power maintenance and needs to be improved. Therefore, we propose a hook that can rotate insulated operating lever. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In a specific embodiment of the present utility model, the insulating joystick is made of glass fiber reinforced plastic (FRP), the bottom ring 3 and the hollow cylinder 14 are formed by an integral mold, the bottom of the bottom ring 3 is connected to the top of the insulating rod body 2 by hot-melt bonding, the truncated cone seat 15 is inserted into the hollow cylinder 14 and the rack 13 is passed through the vertical groove 1401 and is interference fit with the concave hole on the circumferential surface of the truncated cone seat 15, after the bottom end of the column 12 is threadedly matched with the top end of the truncated cone seat 15, the rotating sleeve 4 is sleeved on the outside of the rotating sleeve 4, and then the top ring 5 is hot-melt bonded to the top of the hollow cylinder 14. At this time, the rotating sleeve 4 is confined between the top ring 5 and the bottom ring 3, and the bottom end of the matching seat 7 is bonded to the top ring 5. Then, the spring 11 is sleeved on the upper layer of the column 12 and the top cover 10 is sealed on the top of the column 12. When the spring 11 is in a stretched state (such as Figure 2 As shown), the rack 13 is located in the upper layer of the vertical groove 1401, and the rack 13 is meshed with the teeth of the inner cavity of the inner gear ring 401. At this time, the rotating sleeve 4 cannot move relative to the insulating rod body 2, so that the insulating rod body 2 can accurately control the hook 6 to maintain and operate the power system. The hexagonal sleeve 9 and the matching sleeve seat 8 are integrated. The inner diameter of the hexagonal sleeve 9 can be made into different sizes according to market demand, but the matching sleeve seat 8 needs to be consistent. In order to ensure that the matching sleeve seat 8 can cooperate with the cavity 701 of the matching seat 7, when the matching sleeve seat 8 and the cavity 701 of the matching seat 7 are perfectly embedded, the block group 703 and the slot group 801 are in an embedded and engaged state, so that the matching sleeve seat 8 and the matching seat 7 rotate synchronously.

[0023] In the preferred technical solution, a cavity one 701 connected to cavity two 702 is provided on the upper layer of the mating seat 7, a block group 703 is provided on the inner wall surface of the cavity one 701, a mating sleeve seat 8 is integrally formed at the bottom of the hexagonal socket 9, and a slot group 801 for engaging with the block group 703 is provided on the outer wall surface of the mating sleeve seat 8. The block group 703 is arranged to cooperate with the slot group 801, so that the mating seat 7 and the mating sleeve seat 8 rotate synchronously.

[0024] In the preferred technical solution, the top end of the column 12 is located inside the hexagonal socket 9, the top plane of the column 12 is threadedly connected to the top cover 10 for blocking the spring 11, the top plane of the column 12 is provided with a bolt head, and the middle of the top cover 10 is provided with a threaded hole, which can be used to realize the threaded matching connection between the column 12 and the top cover 10.

[0025] In the preferred technical solution, the vertical length of the vertical groove 1401 is 2.5 times the vertical length of the rack 13. When the spring 11 is in the extended state, the rack 13 is located at the upper end of the vertical groove 1401, and the vertical groove 1401 reserves a sufficiently long descending space for the rack 13.

[0026] In the preferred technical solution, a screw is provided at the bottom end of the column 12, and a threaded hole is opened on the top surface of the truncated pedestal seat 15. The bottom end of the column 12 and the top end of the truncated pedestal seat 15 are detachably connected to facilitate assembly of the column 12 and the truncated pedestal seat 15.

[0027] In the preferred technical solution, a plurality of recessed holes are formed around the outer circumferential surface of the truncated cone seat 15, and the rack 13 is connected to the recessed holes by interference fit, which makes the rack 13 and the outer circumferential surface of the truncated cone seat 15 more tightly connected.

[0028] In the preferred technical solution, an insulating rubber handle 1 is fixedly provided at the bottom end of the insulating rod body 2, and an umbrella edge is integrally formed on the top end of the insulating rubber handle 1. The insulating rubber handle 1 cooperates with the umbrella edge to reduce the risk of water column conducting electricity to the human body.

[0029] Working principle: When the spring 11 is in the stretched state, the rack 13 is located in the upper layer of the vertical groove 1401, and the rack 13 is meshed with the teeth in the inner cavity of the inner gear ring 401. At this time, the rotating sleeve 4 cannot move relative to the insulating rod body 2, so that the insulating rod body 2 can accurately control the hook 6 to maintain and operate the power system. When it is necessary to use the hexagon socket 9 to tighten the wire clamp bolt, it is only necessary to fit the hexagon socket 9 tightly with the wire clamp bolt. After the wire clamp bolt is matched, the column 12 is pushed downward, the spring 11 is adaptively compressed, and the rack 13 and the inner gear ring 401 are staggered up and down. When operating the insulating rod body 2 to tighten the wire clamp bolt, the hook 6 encounters an obstacle without affecting the normal and smooth rotation of the insulating rod body 2. After the hexagonal socket 9 is separated from the wire clamp bolt, if the rack 13 is not adaptively meshed with the inner gear ring 401, the rotating sleeve 4 can be slightly rotated. When the rack 13 is aligned with the inner teeth of the inner gear ring 401, the rebound force of the spring 11 can make the rack 13 mesh with the inner teeth of the inner gear ring 401. At this time, the rotating sleeve 4 cannot move relative to the insulating rod body 2, so that the insulating rod body 2 can continue to be used to control the hook 6 for power system maintenance and operation.
