Description

Technical Field

[0002] Insulating clamp rods are widely used in power transmission and distribution systems, such as high-voltage transmission lines, substations, booster stations, switchgear, disconnectors, transformers, capacitors, circuit breakers, mutual inductors, etc., all of which require insulating clamp rods for isolation, support, fixation and protection. The insulating clamp rod is composed of a clamp, an insulating rod and a clamp opening and closing control mechanism. At present, if the clamp of the insulating clamp rod needs to keep the clamp always clamped with the cable, it is necessary to continuously press the clamp opening and closing control mechanism to achieve this. This will greatly increase the labor intensity of the hands of power construction workers, and it is easy for the cable to be unclamped and loosened, which poses a safety risk and urgently needs to be improved. Therefore, we propose a self-locking insulating locking rod. Utility Model Content

[0021] 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] Embodiment 1, as Figure 1-4 As shown, the utility model provides a technical solution: a self-locking insulating locking rod, comprising an insulating rod 1, a chuck mechanism 2 and a chuck self-locking adjustment mechanism 3, the chuck mechanism 2 and the chuck self-locking adjustment mechanism 3 are respectively arranged at the head end and the tail end of the insulating rod 1, the chuck mechanism 2 comprises a fixed head 202, a chuck 1 205 is fixedly arranged at the bottom of the end of the fixed head 202, a chuck 201 is hingedly arranged at the end of the fixed head 202 through an axle pin, an extension rod 206 is fixedly arranged at the end of the chuck 201, the extension rod 206 is elastically connected to the fixed head 202 by setting a spring 1 203, the extension rod 206 is connected to the intermediate insulating sliding mechanism through a rope body 1 207, the intermediate insulating sliding mechanism comprises a slide seat 1 210 and a slider 1 209, and one end of the slider 1 209 is connected to the chuck self-locking adjustment mechanism 3 through a rope body 2 4;

[0023] The chuck self-locking adjustment mechanism 3 includes a slide seat 2 301 and a slider 2 305, one end of the rope body 2 4 is connected to one end of the slider 2 305, and a pull ring 306 is fixedly provided on the other end of the slider 2 305, a tooth row 1 309 is fixedly provided on one side surface of the slider 2 305, and a tooth row 2 302 is slidably embedded on the surface of the slide seat 2 301 close to the tooth row 1 309, and the tooth row 1 309 is meshed with the tooth row 2 302, and an elastic mounting mechanism for elastically connecting with the tooth row 2 302 is provided on the top of the tooth row 2 302.

[0024] In a specific embodiment of the present invention, chuck 1 205 is fixed to the lower part of the end of fixed head 202, chuck 201 is hinged to the end of fixed head 202 by an axle pin, and chuck 201 is located above chuck 1 205. When spring 1 203 is in a stretched state, chuck 201 and chuck 1 205 are in an open state. When the pull ring 306 indirectly pulls the extension rod 206 to rotate, chuck 201 and chuck 1 205 are controlled to close. At this time, spring 1 203 will gradually compress, and the lifting ring 303 pulls up tooth row 2 302 to separate tooth row 2 302 from tooth row 1 309, so that the resilience of spring 1 203 restores chuck 201 and chuck 1 205 to an open state. The teeth of tooth row 1 309 and tooth row 2 302 are both in the shape of right-angled trapezoids, and the inclined surface of tooth row 1 309 is parallel to the inclined surface of tooth row 2 302 (such as Figure 4 As shown in the figure), when the pull ring 306 is pulled to make the slider 2 305 move along the right side of the slide seat 2 301, the tooth row 2 302 will repeatedly separate and engage with the movement of the tooth row 1 309, thereby realizing a one-way self-locking movement, and the chuck of the chuck mechanism 2 can be suspended at a specified position without the need for continuous force, so that the chuck mechanism is more stable when clamping the cable. When it is necessary to restore the chuck 201 and the chuck 1 205 to the open state, it is only necessary to lift the tooth row 2 302 through the lifting ring 303, so that the teeth of the tooth row 1 309 are separated from those of the tooth row 2 302, thereby cooperating with the elastic rebound of the spring 1 203 to switch the chuck 201 and the chuck 1 205 to the open state, thereby releasing the clamping of the cable.

[0025] In the preferred technical solution, the elastic mounting mechanism includes an L-shaped frame 304 fixed to the outside of the second slide seat 301, and a column is provided through the horizontal seat of the L-shaped frame 304. The bottom of the column is fixedly connected to the back of the second gear row 302, and a spring 2 307 for elastic movement of the second gear row 302 is embedded in the middle of the column. The column and the spring 2 307 are provided to realize the elastic movement of the second gear row 302.

[0026] In the preferred technical solution, a lifting ring 303 for lifting the second gear row 302 is fixed by bolts at the center position of the back side of the second gear row 302 . The lifting ring 303 is provided to facilitate lifting the second gear row 302 .

[0027] In the preferred technical solution, the slide seat 210, the slider 1 209, the slide seat 2 301 and the slider 2 305 are all made of insulating material, and the insulating material is polytetrafluoroethylene. The insulating material can prevent electrical contact between the cable and the operator, thereby improving safety. The slide seat 210 and the slider 1 209 are consistent with the traditional slide rail slider structure. The slider 1 209 slides on the slide seat 1 210 (slide rail), and a slot is provided to limit the separation of the slide seat 1 210 and the slider 1 209. The slide seat 2 301 and the slider 2 305 are also not much different from the traditional slide rail slider structure, except that a tooth row 1 309 is provided on the side wall of the traditional slider, and a tooth row 2 302 that can elastically move up and down is provided on the side wall of the traditional slide rail, so that the slider 2 305 can be self-locked when it moves in one direction, and cannot move in the opposite direction when the tooth row 1 309 is engaged with the tooth row 2 302.

[0028] In the preferred technical solution, the rope body 1 207 is a steel wire rope to ensure its stability in use, and the rope body 2 4 is a PVC braided rope to ensure insulation and improve safety.

[0029] In the preferred technical solution, a guide wheel 208 is rotatably arranged on the outside of the fixed head 202 through a bracket, the rope body 207 is overlapped in the guide groove of the guide wheel 208 and the end is connected to a slider 209, and the guide wheel 208 is used to guide the rope body 207 to maintain a horizontal connection with the slider 209.

[0030] In the preferred technical solution, a clamping column 204 for clamping and installing with spring 1 203 is fixedly provided on the outside of the fixed head 202, and a protrusion for clamping and installing with spring 1 203 is fixedly provided on the outside of the extension rod 206. The clamping column 204 cooperates with the protrusion to limit the position of spring 1 203.

[0031] In summary, based on the fact that the traditional chuck-type insulating locking rod cannot achieve self-locking of the chuck, this embodiment designs a method of pulling the chuck to close by means of a pull ring. By insulating the components in contact with the chuck, the safety of the operation is ensured while achieving the self-locking effect during the chuck merging process. By pulling up the lifting ring 303, the chuck structure can be restored to the expanded state with one click, which is convenient and easy to use.
