Description
Technical field
The utility model relates to a kind of hydraulic pressure tightener, particularly a kind of replacing high-voltage transmission line insulator hydraulic pressure tightener.
Background technology
The three-phase conducting wire of ultra-high-tension power transmission line is suspended on the electric power line pole tower by insulator string mostly.Insulator string is formed by multi-disc dish-type insulator head (bulb) tail (the steel cap of dribbling nest) serial connection, and every insulator all has very high electric and mechanical strength, has guaranteed the reliability service of transmission line.But after operation for many years, deterioration can take place and lose efficacy in indivedual insulators, need change at any time.For not because of changing insulator with line outage, just need on ultra-high-tension power transmission line, carry out live line working, directly do not contact high-voltage conducting wires or carry out operation by the workman under the power-off condition at circuit by means of insulating tool; Simultaneously, for a slice deterioration insulator is taken out from an insulator string, must use a kind of special mould clamp that has tightening device, to be the insulator (totally three insulators) that makes deterioration insulator and both sides become relaxed state from tension (because of some tons weight of suspension lead makes insulator string be in tensioned state) to purpose, under relaxed state, the bulb of deterioration insulator and steel cap could be thrown off from the steel cap of adjacent insulator correspondence and bulb, it be taken out from suspension insulator change.Domestic employed this type of jig is made of the last jig that has scissor shutter door and following jig and screw tightener at present, and last jig and following jig are arranged in parallel, and are separately fixed at the two ends of screw rod tightener, and the middle part of jig has the open and close type annulus; The two ends of tightener one rhizoid thick stick prepare forward screw thread and reverse thread respectively, the two ends of leading screw are screwed in respectively in the screw of jig and following jig, manually pull the handle that is fixed on the screw rod leading screw, the insulator that is held is tightened up or loosen thereby go up jig and play jig translation during rotating screw bolt, corresponding industry standard is " DL/488 live line working with plate-shaped suspension type insulator jig ".The screw rod tightener major defect be: tighten up for going up jig and play jig (1), and the need manpower is operated, and wastes time and energy.(2) belong to contact operation, the risk that the workman need emit high pressure to get an electric shock and fall from high altitude.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned prior art deficiency, and a kind of replacing high-voltage transmission line insulator hydraulic pressure tightener is provided, but the utility model need not dependent manual operation, and noncontact remote control, easy to use.
The technical solution of the utility model is to solve like this:
Be connected with hydraulic cylinder by connecting rod between the jig under the last jig, an end and the hydraulic cylinder of connecting rod are fixedly linked, and stretch with the piston motion of hydraulic cylinder, and hydraulic cylinder is connected with oil pump, and wherein a side oil pump is connected with hydraulic drive mechanism controller, DC motor.
The hydraulic drive mechanism controller is connected with remote signal receiver, and remote controller can send the control signal of telecommunication to the remote signal receiver wireless remote control.
When using the utility model to carry out the charged for replacement insulator on ultra-high-tension power transmission line: the workman uses remote controller remote operation hydraulic drive mechanism controller on shaft tower, make the hydraulically extensible bar folding of hydraulic pressure tightener, thereby will go up jig, down jig is opened or be closed.
Adopt the utility model structure workman need not the manual operation tightening device, reduced labour intensity.The workman need not exempt the danger that high pressure gets an electric shock and fall in the high-altitude has taken place near insulator string or high-voltage conducting wires again, has improved the fail safe of live line working.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing content of the present utility model is described in further detail.
Embodiment
As shown in Figure 1, the charged for replacement high-voltage transmission line insulator is the hydraulic drive mechanisms that are made of battery 5, DC motor 6, oil pump 7, hydraulic cylinder 8, connecting rod 9, hydraulic drive mechanism controller 10, remote signal receiver 11 with hydraulic pressure tightener 4, and battery 5 provides the energy for hydraulic drive mechanism.One end and the hydraulic cylinder 8 of connecting rod 9 are fixedly linked, and can stretch with the piston motion of hydraulic cylinder 8, and the other end of connecting rod 9 is connected with last jig 1 mechanical fixation or jig 2 mechanical fixation connection down; Battery 5, oil pump 7, DC motor 6, hydraulic drive mechanism controller 10 and remote signal receiver 11 mechanical fixation are connected on the tightening device 4, remote controller 12 does not have machinery with tightening device 4 and is connected, and can send the control signal of telecommunication to remote signal receiver 11 wireless remote controls.
During the charged for replacement high-voltage transmission line insulator, the device that is made of the last jig 1 that has scissor shutter door 3 and following jig 2, hydraulic pressure tightener 4 carries out.The shutter door 3 of last jig 1 and following jig 2 is an annular, and shutter door 3 lays respectively at the middle part of jig 1 and the middle part of following jig 2, and last jig 1 and following jig 2 are arranged in parallel, and can be held on the steel cap of the upper and lower side insulator of deterioration insulator.
When carrying out the operation of charged for replacement insulator, after with insulation rope this mechanical arm being risen to the appropriate location by the workman on the shaft tower, control the shutter door 3 of jig 1 and following jig 2 respectively with insulating bar, allow jig 1 and following jig 2 be clamped to respectively on the steel cap of upper and lower side insulator of deterioration insulator, make it block three insulators.
Below in conjunction with Fig. 1 and Fig. 2 description operation process: the workman on shaft tower with remote controller 12 far distance controlled hydraulic pressure tighteners 4, remote controller 12 sends " tightening up " instruction, after remote signal receiver 11 receives this instruction, start DC motor 6 by hydraulic drive mechanism controller 10, driving oil pump 7 shrinks hydraulic cylinder 8, make jig 1 and following jig 2 tighten up the distance of a regulation simultaneously to the middle part by connecting rod 9, the insulator of deterioration insulator and upper and lower both sides becomes relaxed state from tension.After the workman takes out spring catch between insulator with special insulating tool, pitch with insulation the deterioration insulator is taken out from insulator string.After same instrument changes to new insulator, the workman uses remote controller 12 far distance controlled hydraulic pressure tighteners 4 again on shaft tower, remote controller 12 sends " loosening " instruction, after remote signal receiver 11 receives this instruction, make hydraulic cylinder 8 retractions by hydraulic drive mechanism controller 10, make jig 1 and following jig 2 oppositely relax to original position, three insulators in the jig revert to stress.This remote control jig is regained with insulation rope and insulating bar by the workman at last, finished operation.
