Description

Technical Field

[0001] The invention relates to a quick locking device for fixing an overhead line and a working method thereof. Background Art

[0002] With the widespread use of overhead insulated conductors, more and more problems have emerged in the method of fixing insulated conductors with traditional BV binding wires. In addition to the complex construction, stress concentration at the binding site often leads to damage to the insulation layer and corrosion of exposed conductors, greatly reducing the service life of the insulated wires; especially in coastal areas, due to long-term salt spray corrosion and wind vibration stress corrosion, serious strand and wire breakage phenomena even occur at the binding site, which brings huge challenges to the operation and maintenance of distribution network lines and seriously affects the reliability of distribution network line operation.

[0003] Based on the above problems, the present invention changes the traditional binding method and proposes a fixed wire clamp for quickly locking the wire. It not only has a simple installation process and a reliable structure, but also can well protect the insulation layer of the wire and extend the service life of the insulated wire in coastal areas.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a quick locking device for fixing overhead lines, comprising a wire clamp body and a wire clamp cover plate, the wire clamp body and the front end of the wire clamp cover plate are hinged through a hinge pin, a circular arc wire groove for the insulated wire to extend left and right is provided between the wire clamp body and the wire clamp cover plate, the rear end of the wire clamp cover plate is placed in a clearance opening opened on the surface of the wire clamp body, connecting holes are opened on the wire clamp body on the left and right sides of the clearance opening, and the wire clamp cover plate is clamped by a pull ring, and the two ends are inserted into the connecting holes to connect with the wire clamp body.

[0006] Furthermore, the wire clamp body includes, from front to back, a hinge hole, a body clamp, a body connecting block and a body crimping tube. A rubber pad mounting groove is recessed downward on the surface of the body clamp. The rubber pad mounting groove is also symmetrically arranged on the wire clamp cover plate. Rubber pads are installed in the rubber pad mounting grooves. Two circular arc grooves are symmetrically arranged on the rubber pad up and down, and the circular arc grooves pass through the rubber pad from left to right.

[0007] Furthermore, the said giving way opening is opened from top to bottom on the main body connection block, the rear end of the main body connection block is fixedly connected to the main body crimping tube, and the main body crimping tube is connected and fixed to the insulating cross arm by being sleeved outside the insulating cross arm.

[0008] Furthermore, a positioning boss is fixedly provided on the end surface of the rubber pad opposite to the arc groove, and a positioning groove for installing the positioning boss is opened in the rubber pad installation groove.

[0009] Furthermore, the wire clamp cover plate includes an integrally formed cover plate clamp and a cover plate adjustment block, a cover plate adjustment block construction hole and a limit groove cooperating with the pull ring are opened on the top of the adjustment block, a number of limit grooves are arranged at intervals front and back, and all extend horizontally to the left and right, and the recessed depths of the limit grooves are not consistent; the rubber pad installation groove is recessed from bottom to top on the cover plate clamp.

[0010] Furthermore, the pull ring is in a U-shape with its opening facing downward, and both ends thereof are bent inwardly by 90 degrees so as to be inserted into the connecting hole.

[0011] Furthermore, a wire-releasing hanging ring with an elliptical long slot hole is fixedly connected to the lower end of the main body chuck, and the elliptical long slot hole passes through the wire-releasing hanging ring from left to right.

[0012] A working method of a quick locking device for fixing an overhead line is performed according to the following steps: first, a wire clamp cover is flipped upward to open, and an insulated wire is placed in a circular arc wire groove, then the wire clamp cover is closed, and a special installation tool for the wire clamp is used to penetrate into a construction hole of a cover plate adjustment block of the wire clamp cover, so that upper and lower rubber pads press the insulated wire, and then a pull ring is put on the hoop, so that the upper end of the pull ring is matched with a corresponding limit groove of the cover plate adjustment block of the wire clamp cover, and the lower end is inserted into a connecting hole, and the compression and resilience of the rubber pad are used to ensure stable matching between the pull ring and the wire clamp cover, and the installation is completed.
