Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line construction, in particular to a ground potential installation shunt device. Background Art

[0002] When erecting the guide, a tension clamp is required at the connection between the guide and the pole tower. In addition to fixing the drainage line, the tension clamp is often used as a connection fulcrum for the jumper. When the installed tension clamp or the boltless compression combined tension clamp connection plate is deformed or broken, it is mainly carried out by cutting off the original drainage and then re-erecting a new drainage line, or adding a shunt line. At the same time, since the existing crimped tension clamp is mainly provided with a drainage plate on the crimped tension clamp body, which is used to cooperate with the drainage pipe to lock and combine to complete the connection between the guide and the jumper of the pole tower, a part of the drainage plate The end has an extension piece, and the end of the drainage tube that is opposite to the drainage plate also has an extension piece. The two extension pieces are respectively provided with lock holes that match each other. The bolts are locked on the lock holes of the two extension pieces to form a corresponding locking combination. During use, this connection method often vibrates due to environmental reasons, which further causes the bolts to loosen. After that, the resistance at this position increases due to the reduction in contact area, which will cause heat at the jumper. Long-term continuous heating will cause the jumper connection to fail, and eventually burn out due to poor current flow, thereby affecting normal power supply.

[0003] The cam is connected to the clamping plate by a spring and is fixed to the clamping plate to release the clamping plate from the clamping plate, so that the clamping plate is fixed to the clamping plate, and the clamping plate is fixed to the clamping plate to release the clamping plate from the clamping plate. The cam body is provided with a through hole which passes through the inner side of the clamping head body, and the lower end of the guide rod is connected with contacts which can disengage the two ends of the top plate from the inner sides of the upper ends of the two tongue plates after passing through the through hole. The insulating operating rod comprises an ordinary insulating operating rod and an insulating operating rod with an iron magnet, and the insulating operating rod with an iron magnet comprises a card mounting groove connected to the rod body and the upper end of the rod body, and the card mounting groove is a cylinder, a strong magnet is provided at the bottom of the cylinder, and a snap mounting groove is provided at the opening of the cylinder; when in use, one of the clamping head bodies is the upper clamping head body and the other clamping head body is the lower clamping head body. The insulating operating rod is used to hang the upper clamping head body on the wire installation position through the lifting ring, and the upper clamping head body is lowered. The contact is pushed upward by the wire, so that the top plate is disengaged from between the two tongue plates and the upper parts of the two tongue plates are clamped by the spring lifting pin. Then the insulating operating rod is disengaged from the lifting ring, and the jumper adopts the insulating operating rod with an iron magnet to hang the lower clamping head body on the carded jumper, and then rotates in the opposite direction to disengage the insulating operating rod to complete the operation.

[0004] The complete set of tools for installing the ground potential shunt strip solves the problem of heating defects, but the two tongue plates clamp the wires or jumpers under the action of the spring push pin, and the tongue plate and the spring push pin are fixed by the torsion spring and the spring is hinged to the clamp body, so that the clamping of the entire tongue plate to the wire depends on the elasticity of the spring and torsion spring. The spring and torsion spring will experience elastic fatigue after a period of use, resulting in a low clamping degree of the tongue plate to the wire, which in turn affects the use of the ground potential installation shunt device.

[0005] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Summary of the Invention

At this time, the arc block 52 of the locking plate 5 moves upward under the relative action of the wire, and the left side of the locking plate 5 is disengaged from the right side of the upper clamping piece 2. The first upper section body 22 of the upper clamping piece 2 swings to the right. At this time, the upper wedge block 3 moves downward under the downward pressure of the fastening block 4 and squeezes the upper clamping piece 2 to the right, so that the wire falls into the first right concave arc of the upper clamping piece 2 and the upper clamping piece 2 clamps the wire. Then, the jumper is extended from a straight section 201 into the second arc section 202. The jumper It falls into the second right concave arc of the lower clamp 6. At this time, the screw 9 is rotated, and the lower wedge block 8 moves up and down on the screw 9 into the lower clamp body and squeezes the lower clamp 6 to the right, so that the lower clamp can clamp the jumper more firmly; compared with the existing technology, all structures of the present invention adopt a spring-free structure to fix the wires or jumpers, and will not cause elastic fatigue. It solves the problem that the springs and torsion springs of the existing ground potential installation shunt device will experience elastic fatigue after a period of use, thereby causing the tongue plate to have a low clamping degree on the wire, thereby affecting the use of the ground potential installation shunt device.

[0032] In the present invention, preferably, the top surface of the upper clamp 2 is provided with an arc-shaped protrusion protruding upward, and the upper block 31 is provided with a through groove running through in the left and right directions, the right end of the arc-shaped protrusion extends into the through groove, and the right end of the arc-shaped protrusion is above the lower block 32, and the left end of the locking plate 5 is pressed against the right side surface of the arc-shaped protrusion; when used, the cooperation of the through groove and the arc-shaped protrusion enables the upper clamp to be more stably limited in the upper clamp body.

[0033] In the present invention, it is preferred that a chimeric block is convexly provided on the left side surface of the above-mentioned first upper section 22, and an embedding cavity for the chimeric block to be embedded is concavely provided on the left side wall of the first vertical section 11; when used, when the upper clamp 2 is limited in the upper clamp body, the upper clamp 2 is further limited by the cooperation of the chimeric block and the embedding cavity.

[0034] The product form of the present invention is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the present invention.
