Description
Technical Field
The invention relates to the technical field of electric power wiring detection, in particular to a push-pull locking type high-altitude wiring device.
Background
According to the maintenance test regulations of the power company, when a high-voltage circuit breaker carries out preventive tests such as loop resistance, PT/CT dielectric loss and capacitance test, on-site maintenance test personnel often use high-altitude wiring clamps to hang test wires for the tests. The height of the existing 500kV high-voltage circuit breaker is generally about 10 meters, the length of a used high-altitude wiring clamp device is also about 10 meters, and the weight of an operating rod of the high-altitude wiring clamp and a test wire reaches 15 kilograms. Although the weight of a single rod is not heavy, the gravity center of the operating rod of the overhead wire connecting clamp is far away from the operating part of a human hand, the generated force arm is large, and then the operating rod can be lifted by an abnormally large operating force. And because lack guider and strutting arrangement, on-spot peg often can not accurate control action bars's direction, leads to pole falling and disconnected pole risk easily. In addition, when field test, especially when the synchronous test is needed, the test method requires three-phase synchronous test, so 3 high-voltage wires and 6 low-voltage wires need to be hung at the corresponding positions of three phases respectively, 9 test wires are needed in total, 9 high-altitude wiring clamp operating rods need to be used, and the total weight exceeds 135 kilograms. The traditional hanging rod and hanging method have great potential safety hazards: firstly, the direction of an operating rod cannot be accurately controlled, and the risks of damaging power equipment and personal injury caused by rod reversing exist; secondly, the operating rod of the high-altitude wiring clamp device is too long and heavy, and a gravity supporting device is not arranged at the middle upper part of the operating rod, so that the shearing force at the lower part of the operating rod is too large, and the risk of rod breaking exists; thirdly, the number of the required high-altitude wiring clamp operating rods is large, 9 operating rods and test wires of 15 kilograms are required for simultaneous three-phase measurement according to the number of the three operating rods which are hung on one phase, and the labor intensity of field personnel is increased, and especially when the high-altitude wiring clamp works in extreme weather, the safety risk of personnel and equipment can be brought.

If insulating action bars 12 is longer, when heavier moreover, adopt above operation probably because the action bars is too long not good control, lead to hanging inefficiency, even fall the pole and pound equipment or personnel, consequently, can be with the help of pulley lever 2 to its supplementary hanging, specific step is:
s11 is first tied to the upper end of the insulated operating rod 12 at one end and then passed through the pulley 22.
S12 allows the pulley lever 2 to be hung on a wire to be tested, and is more convenient to operate because the pulley lever 2 can be made light because it needs to bear less weight.
S13 the terminal rod 1 is connected according to the steps of S1 ~ S3.
S14 pulls the other end of the pulling rope to pull the insulated operating rod 12 to the high altitude.
S15 is used to hang the connector pole 1 on the conductor to be tested.
S16 pulls the release cord which slides the guide cap 1118 down so that the collar 11150 slides under the bead 11172 and the connecting mechanism 11 returns to the position of FIG. 6, at which time the insulated actuating rod 12 is free to be pulled out.
