Background
The insulating operating rod is also called as ground wire mounting device, which is a safe operating tool for mounting and dismounting ground wires in power production, and the structure of the insulating operating rod is partially disclosed in China patent No. 201210530971.8 entitled "high-voltage ground wire safety mounting and dismounting device", and the specific structure of the insulating operating rod comprises an insulating sleeve or sleeve, a chuck, a pull rod, an operating trigger, a driving rack, a positioning mechanism and a reset mechanism. The chuck comprises three open-close type claws which are slidably arranged at the top end of the sleeve through fixing sheets, and in a natural state, the three claws extend out of the top end of the sleeve to keep the chuck in an open state. The driving rack is vertically and slidably arranged at the bottom of the sleeve, the operating trigger is controlled by the pressing handle, one end of the trigger is hinged to the trigger frame, the other end of the trigger stretches into the sleeve and is matched with teeth of the driving rack, the pressing handle is connected to the middle part of the trigger, the trigger is controlled to act through the pressing handle, the rack moves downwards for a certain distance when the trigger toggles the rack once and is positioned by the positioning mechanism, the top end of the rack is connected with the pull rod, the rack moves downwards to drive the pull rod to move downwards, so that the hook claw is pulled to move downwards, and after the spanner acts for several times, the hook claw part can be pulled back into the sleeve, so that the chuck is clamped. When the ground wire is required to be loosened, the positioning pin is pressed, the positioning mechanism is released, the rack is driven to move upwards under the action of the reset spring, the pull rod is driven to ascend, the claw protrudes out of the sleeve, and the chuck is opened.
The mounting device is simple to operate and good in use effect, and is widely applied to mounting and dismounting operation of the high-voltage grounding wire of the power supply system.
Because of various kinds of equipment of a power supply system, various factors such as different positions of the ground wire and different voltage levels are required to be installed, the following problems are encountered in the installation and removal processes of the ground wire:
1) The installation positions are different, when the grounding wire is installed or removed, the clamping head is required to continuously adjust the installation direction, so that an operator is required to continuously adjust the operation rods front, back, left, right, up and down;
2) The equipment for installing the grounding wire is different, the size of the clamping opening of the grounding wire is required to be adjusted to adapt to different sizes of the equipment in the process of installing or dismantling the grounding wire, so that the size and the clamping force of the grounding wire clamping opening are required to be continuously adjusted by operating the trigger through the handle, the requirement on the holding force by pressing the operating trigger by hand is high, the labor intensity is high, if the number of the grounding wires to be assembled and disassembled is large, operators cannot independently bear the high labor intensity, a plurality of people are required to operate in turn, a large amount of labor force is consumed, and the working efficiency is low;
3) The voltage level of the field equipment of the transformer substation is different, the insulation distance, the equipment volume and the height are different, so that the length of the ground wire gun is different, namely, the length of the sleeve is long, the length of the sleeve with high voltage level is long, the length of the sleeve with low voltage level is short, the short operating rod is relatively easy to operate, but if the voltage level of the equipment is high, the length of the operating rod is long, the weight of the upper part of the operating rod after the ground wire clamp is clamped is too heavy, the operating rod cannot be lifted to the installation position by an operator by means of personal force, however, guardians do not allow participation in operation in the transformer operation and maintenance switching operation, so that the ground wire hanging work of a certain high voltage level cannot be completed by the ground wire gun alone, and sometimes the operation is assisted by means of an insulating arm car, and the difficulty, the time and the cost of operation are greatly increased.
