Description
Technical field
The invention belongs to electric power overhaul Work tool technical field, specifically, relate to an a kind of phasing servicing unit of trolley type switch.
Background technology
In electric power system, the grid-connected four factor of two electric power systems is that the phase sequence of two power supply grids is consistent, electric pressure is identical, phase place is identical and frequency is identical, so must the phase sequence of detection of grid before grid-connected; Along with the development of China's regional economy, power demands constantly increases, user's many employings multiloop or double circuit power supply, if certain current supply circuit breaks down, then can pass through other looped network point by power delivery to user, before this, whether necessary Check Phase Sequence is correct; In addition, after major repair of track or rectification, before resuming operation, whether unanimously also must check phase sequence before and after running.
Phasing can only carry out at the place of electrified body up and down in station in switch cubicle.For fixed (middle) switch cubicle, during phasing, phasing gage directly can be touched the Naked dew part of upper and lower two electrified bodies of switch, operate very easy, and for trolley type switch, fixed contact is closed by insulation barrier, insulation barrier compares and is difficult to open and fix, phasing operation will be very difficult, first car switch to be pulled in switch cubicle its maintenance position during phasing, then controlled with the left and right opening door link gear of insulating bar to insulation barrier in switch cubicle by two staff, insulation barrier is opened and maintains, the phasing operation of being correlated with is carried out again by other two staff, whole phasing need of work 4 staff participate in simultaneously, the manpower dropped into is on the high side, when two staff open insulation barrier with insulating bar, the power thrusts of two people is difficult to consistent with size, insulation barrier is caused to open difficulty, open incomplete or tilt, make inefficiency, and there is larger security risk.
Summary of the invention
The object of this invention is to provide a kind of when phasing handling safety, drop into the few and aid vehicle device for a car switch phasing that operating efficiency is high of manpower.
For realizing above-mentioned technical purpose, aid vehicle device for a car switch phasing of the present invention, include main body of vehicle frame, safety protective door and shift fork, retractable safety protective door one end is hinged on main body of vehicle frame, on main body of vehicle frame by slide rail symmetry be provided with left and right two slide blocks, left and right slide block is provided with walking roller, shift fork for stirring insulation barrier door-opening linkage mechanism is provided with two, left and right, the top being arranged on left and right slide block side front end that left and right shift fork is corresponding respectively, left and right slide block is connected with the telescoping mechanism be arranged on main body of vehicle frame, main body of vehicle frame is provided with the Telescopic positioning device of left and right slide block.
Safety protective door is in order to ensure the safe distance of staff and electrified body to greatest extent, and the radiation of anti-gear arc light, guarantees the personal safety of operating personnel.Left and right two slide blocks can horizontally slip thus extended or retracted main body of vehicle frame, to adapt to the needs of the trolley type switch of different model under the drive of telescoping mechanism.During use, left and right slide block adjusted to the right place by telescoping mechanism and with Telescopic positioning device, left and right slide block is located, making it to keep relative between main body of vehicle frame and fix.This aid vehicle to be placed on the track in trolley type switch cabinet and to rise safety protective door, promote this aid vehicle inwards, the handle up and down of insulation barrier door-opening linkage mechanism fastens by left and right two shift forks simultaneously, thus insulation barrier is opened, then safety protective door is put down, make safety protective door be retracted to close to level, at this moment just can carry out phasing operation.Open insulation barrier with two shift forks of this aid vehicle and make insulation barrier maintain open mode easily, thus phasing operation only just need can be completed by two staff.
Telescoping mechanism is made up of gear and left and right tooth plate, gear is arranged on retainer, and retainer is fixed relative to main body of vehicle frame, and gear engages with left and right tooth plate simultaneously, left and right tooth plate is direct or indirect to be respectively connected with left and right slide block, and the upper surface of gear is provided with the groove matched with rotating spanner.Make pinion rotation with rotating spanner, then gear driven left and right tooth plate moves in opposite directions or dorsad, drives left and right slide block to make stretching motion in main body of vehicle frame, is used for adjusting the width of whole aid vehicle, to adapt to the needs of different model trolley type switch.
Telescopic positioning device is made up of backstay, Compress Spring and positioning knob, between the block of Compress Spring on backstay and main body of vehicle frame rear end panel, backstay is located on the slide block of left and right, main body of vehicle frame front console is provided with location hole, the rear end panel of main body of vehicle frame is provided with via hole, and left and right slide block is provided with bar hole, and backstay one end is connected with positioning knob with via hole through bar hole, positioning knob is provided with alignment pin, and the pin-and-hole on this alignment pin and main body of vehicle frame rear end panel matches.When needs adjustment left and right slide block, positioning knob is pulled outwardly with hand, drive backstay exits the location hole on main body of vehicle frame front console, alignment pin on positioning knob also exits from the pin-and-hole the panel of main body of vehicle frame rear end, let go after rotating to an angle, because the alignment pin on positioning knob is resisted against on the panel of main body of vehicle frame rear end, thus make backstay remain exit status relative to the location hole on main body of vehicle frame front console, at this moment just control left and right slide block by telescoping mechanism and carry out stretching motion relative to main body of vehicle frame; When after flexible putting in place, backstay targeted by another location hole on main body of vehicle frame front console again, at this moment reverse rotation positioning knob makes it reset, the pin-and-hole on the panel of main body of vehicle frame rear end aimed at by alignment pin on positioning knob, under the effect of Compress Spring, backstay enters location hole, and alignment pin enters pin-and-hole simultaneously.
Present invention ensures that reliable, rapid, safe the opening and maintain of insulation barrier, thus only need two people just can complete phasing operation, save manpower, improve operating efficiency.
