Description

Technical Field

[0001] The utility model relates to the field of electric power construction, in particular to an insulation cover pressing device of an insulation grounding wire clamp of a power distribution line. Background Art

[0002] During the maintenance process of power workers, the grounding wire can prevent the workers from getting close to the live objects and generating electrostatic induction. It can also ensure the safety of the workers in the event of accidental closing of the switch. Temporary installation of the grounding wire is relatively difficult, so installing a reliable insulating grounding wire clamp is the key to ensuring the personal safety of power workers. The structure of the existing insulating grounding wire clamp is as described in patent number "CN217485735U", including a disk body as the main body of the insulating grounding wire clamp, a detachable pressure cover on the disk body, an insulating cover hingedly matched with the disk body, and a grounding ring connected to the disk body. During installation, the cable is first fixed between the pressure cover and the disk body. By screwing the wire clamp bolt, the pressure cover moves toward the disk body to clamp the cable. After clamping, the insulating cover is closed to complete the installation process.

[0003] When working on live distribution networks, installing grounding wire clamps generally requires power workers to climb to the top or use an insulated boom truck to reach the working height. After tightening the clamp bolts, the insulating cover needs to be flipped over and tightened. Manual live working at high altitudes during the flipping process poses a safety risk. At the same time, due to its own structural reasons, the grounding wire is not firmly connected when hung on a suspended vertical conductor or in strong winds. If the insulating cover falls out of the hand after flipping it over, it is easy to swing, so it needs to be solved urgently. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides an insulation cover pressing device for an insulation grounding clamp of a power distribution line. The utility model can automatically flip and press the insulation cover on the grounding clamp, and the operation risk is low.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A device for clamping an insulating cover of an insulated grounding wire clamp for a power distribution line comprises a snap-fit ​​mechanism fixed to a mounting base, on which the grounding wire clamp is detachably arranged; the snap-fit ​​mechanism comprises a front guide fork and a rear guide fork, wherein the front guide fork and the rear guide fork enclose a guide channel with a V-shaped opening, and the tip of the guide channel is in the shape of an arc surface for positioning cables; the snap-fit ​​mechanism also comprises a rotatable gland push claw, wherein the rotation axis of the gland push claw is arranged parallel to the rotation axis of the insulating cover on the grounding wire clamp, and when the gland push claw rotates, a pressing action is exerted on the insulating cover.

[0007] As a further solution of the present invention: the snap-fit ​​mechanism includes a pressure cover push rod fixed on the mounting seat, and the driving end of the pressure cover push rod is arranged with a pressure cover rack along the linear telescopic direction. The pressure cover gear installed on the mounting seat and the pressure cover rack constitute a gear rack matching transmission, and the axis of the pressure cover gear is arranged parallel to the rotation axis of the insulating cover; the pressure cover push claw is driven by the pressure cover gear to rotate coaxially.

[0008] As a further solution of the present invention: a rotating shaft arranged parallel to the rotating axis of the insulating cover is installed on the front guide fork, the rotating shaft and the front guide fork rotate together, and a wire pressing claw rotating with the rotating shaft is coaxially fixed on the rotating shaft, and the rotation trajectory of the wire pressing claw intersects with the tip of the guide channel.

[0009] As a further solution of the present invention, two groups of wire pressing claws are provided, which are symmetrically arranged on both sides of the front guide fork, and the pressing surfaces of the wire pressing claws are in the shape of arc surfaces.

[0010] As a further solution of the present invention: a wire claw push rod is provided on the mounting seat and is hingedly matched with the mounting seat, the hinge axis is arranged parallel to the axis of the rotating shaft, and a rotating shaft connecting rod is coaxially provided on the rotating shaft. The rotating shaft connecting rod is hingedly matched with the working end of the wire claw push rod to form a two-link structure. When the wire claw push rod is extended or retracted, it forms a V-shaped opening and closing action with the rotating shaft connecting rod to drive the rotating shaft to rotate.

[0011] As a further solution of the present invention, the wire claw push rod is located on the same straight line as the rotating shaft connecting rod in the retracted state, and is arranged in parallel with the pressure cover push rod.

[0012] As a further solution of the present invention: a limit rod parallel to the rotation axis of the insulating cover is provided on the front guide fork, the lock buckle on the insulating cover is made of a bendable flexible material, and the rotation trajectory of the lock buckle intersects with the limit rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. When the wire claw push rod of the utility model is extended and retracted, it forms a V-shaped two-link structure with the rotating shaft connecting rod. When it is extended and retracted, it drives the rotating shaft to rotate. After the rotating shaft drives the wire pressing claw to rotate, the wire pressing claw can press the cable to the bottom of the guide channel from top to bottom, avoiding the shaking of the cable during operation. The insulating cover on the grounding wire clamp is automatically flipped and pressed, and the operation risk is low.

[0015] 2. When the wire claw push rod of this utility model is retracted to its limit, it is arranged in a straight line with the rotating shaft connecting rod. At this time, the wire claw push rod is arranged parallel to the gland push rod, maximizing space utilization. The gland push claw rotates coaxially with the gland gear, and when it rotates, it presses the insulation cover. The insulation cover is pressed by the 180-degree rotation of the gland push claw.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-2 In an embodiment of the utility model, an insulation cover pressing device of an insulated grounding wire clamp of a distribution line includes a grounding wire clamp 1. The grounding wire clamp 1 includes a base body and a grounding ring 14 arranged below the base body. Preferably, a groove is opened below the base body, and the grounding ring 14 is positioned by clamping.

[0028] The base of grounding clamp 1 is provided with a cable groove for cable A to clip into. A gland 12 is mounted on the base and secured to the base via a clamp bolt 13. A correspondingly shaped compression groove is defined on the end of gland 12 adjacent to the cable groove. When clamp bolt 13 is tightened to move gland 12 toward the compression groove, the compression groove of gland 12 closes with the compression groove, forming a conductor channel that secures cable A.

[0029] The insulating cover 11 is hingedly connected to the base of the grounding clamp 1, allowing the gland 12 to be placed within the body of the insulating cover 11 after flipping it from top to bottom. A grounding ring groove is defined in the body of the insulating cover 11. When the insulating cover 11 is closed, the grounding ring 14 is positioned precisely within the groove. The restraints of the insulating cover 11 and the base ensure the grounding ring 14 is positioned. The hinge axis of each structure in this application is parallel to the flipping axis of the insulating cover 11.

[0030] A locking tongue 15 is protruding from the bottom of the grounding clamp 1, and a locking catch 16 is provided on the insulating cover 11. When the insulating cover 11 is closed, the locking catch 16 corresponds exactly to the position of the locking tongue 15. The locking catch 16 is preferably made of a flexible, bendable rubber material. By applying an external force to the locking catch 16, it can be flipped 90 degrees from its base. The locking hole is opened on the surface of the locking catch 16, and the locking hole corresponds to the shape of the locking tongue 15 or is slightly smaller than the locking tongue 15. When an external force flips the locking catch 16, the locking tongue 15 passes through the locking hole of the locking catch 16, thereby completing the locking of the insulating cover 11 and the base, preventing the insulating cover 11 from opening.

[0031] The locking mechanism 4 includes a front guide fork 41 and a rear guide fork 42 fixed on the mounting base 2. The front guide fork 41 and the rear guide fork 42 enclose a guide channel 43 with a V-shaped opening. The opening of the guide channel 43 is upward, and the bottom end of the guide channel 43 is coaxially arranged with the wire clamping groove of the grounding wire clamp 1.

[0032] The rear guide fork 42 is located between the front guide fork 41 and the locking mechanism 3. The bottom end of the guide channel 43 is curved to position cables A of different diameters. The front guide forks 41 and the rear guide forks 42 are preferably provided in two sets, and the mounting base 2 is provided between the two front guide forks 41 and the two rear guide forks 42.

[0033] A limiting rod 411 is provided at the top between the two front guide forks 41 . The limiting rod 411 is located on the flipping track of the lock buckle 16 . The lock buckle 16 can pass over the limiting rod 411 after bending.

[0034] A rotating shaft 413 is provided at the bottom end between the two front guide forks 41 , and a wire pressing claw 412 is provided at both ends of the rotating shaft 413 . The pressing surface of the wire pressing claw 412 is in an arc shape for fitting the cable A.

[0035] After the rotating shaft 413 drives the wire pressing claw 412 to rotate, the wire pressing claw 412 can press the cable A against the bottom of the guide channel 43 from top to bottom to prevent the cable A from shaking.

[0036] A wire claw push rod 44 is provided on the back of the mounting base 2 and is hingedly arranged with the mounting base 2. The driving end of the wire claw push rod 44 is hingedly matched with the rotating shaft connecting rod 414. The end of the rotating shaft connecting rod 414 is fixed on the rotating shaft 413. When the wire claw push rod 44 is extended and retracted, it forms a V-shaped two-link structure with the rotating shaft connecting rod 414, driving the rotating shaft 413 to rotate during extension and retraction.

[0037] When the wire claw push rod 44 is retracted to the limit state, it is arranged in a straight line with the rotating shaft connecting rod 414. At this time, the wire claw push rod 44 is arranged in parallel with the pressure cover push rod 45 to maximize space utilization.

[0038] A cover push rod 45 is mounted on the back of the mounting seat 2 along the vertical direction. The fixing method is not limited as long as there is no relative displacement between the cover push rod 45 and the mounting seat 2 during extension and retraction.

[0039] A cover rack 453 is provided on the telescopic end of the cover push rod 45, and a cover gear 451 is installed on the back of the mounting seat 2 through the gear seat. The cover gear 451 and the cover rack 453 form a gear rack transmission.

[0040] A cover pushing claw 452 is coaxially fixed to the cover gear 451. The cover pushing claw 452 rotates coaxially with the cover gear 451 and compresses the insulating cover 11. The insulating cover 11 is compressed by rotating the cover pushing claw 452 180 degrees.
