The terminal end of horizontal cylinder is pivoted to the said metallic base plate. The terminal end of piston is pivoted to drive wedge block. A roller is pivoted to the upper left corner of said drive wedge block. The connecting axle of slide block passes vertically through the relay region on wedge block. The driven insulating wedge block is fixed to the second group of crossed rods.
Description
Technical field
What the present invention relates to is the mechanism in a kind of Robotics field, specifically is a kind of insulated elevating mechanism driven in relay type.
Technical background
Along with the fast development of China's industrial or agricultural technology, users are more and more higher to the requirement of power supply reliability; Meanwhile, industrial pollution and environmental problem are serious day by day, the porcelain bobbin insulator surface of transformer is subjected to the pollution of conducting material for a long time, when running into humidification such as mist, dew and drizzle, pollution layer conductance is increased, leakage current increases, produce shelf depreciation, the grid equipment external insulation pollution flashover fault that causes is thus uprushed thereupon, causes the electric grid large area pollution flashover accident of power outage to take place again and again, thereby the safe operation of serious threat electric system.This can bring about great losses to national economy, brings inconvenience to people's lives.Traditional hand sweeping method labour intensity is big, and safety and cleaning performance can not get guaranteeing, and will just can carry out work under the power failure operating mode.Adopt robot to carry out regular equipment cleaning, replace hand sweeping not only can alleviate the danger of falling in working strength of workers, reduction electric shock and high-altitude, and can under situation about not having a power failure, carry out the live cleaning operation, thereby keep the actual stain resistance of equipment effectively, reduce pollution flashover accident and have a power failure the influence of cleaning industrial and agricultural production and people's daily life.
Through the literature search of prior art is found: patent of invention number 01126817.4, name is called " type super high voltage live cleaning robot ", this sweeping robot adopts the single-stage scissor-type lifting mechanism, its dipping and heaving relies on up and down, and two two radial type hydraulic rams drive, its middle and lower part oil cylinder is the metal oil cylinder, and the top oil cylinder is the insulation oil cylinder.This lifting mechanism adopts the dielectric compressing cylinder, its objective is in order to have enough effective insulation distances between the clean-up paw that guarantees robot contact electrification body when the cleaning work and the earth potential, to guarantee to be cleaned the insulation safety of electrical equipment and robot self.But in the middle of the application of reality, this lifting mechanism shows the some shortcomings part: 1. single-stage scissor-type lifting mechanism integral structure weight is big, and its adjustable height and complete machine non-conductive relation can't be adjusted.2. the operation pressure of employed pair of radial type dielectric of this insulated elevating mechanism compressing cylinder is very big, because the design of insulation oil cylinder is still under test at present, its design and manufacture difficulty are big, and reliability is relatively poor, and its service life or unknown number.
Summary of the invention
The present invention is directed to problems of the prior art, a kind of insulated elevating mechanism driven in relay type is provided,, can control its lifting action separately as effective over the ground insulation distance of type super high voltage live cleaning robot.This mechanism comprises three groups of insulation fork arms, the mode that adopts horizontal metal hydraulic ram and wedge combinations relay to drive.The present invention is simple in structure, and is in light weight, not only avoided insulation oil cylinder design-calculated expensive, and greatly improved the reliability of mechanism's dipping and heaving.
The present invention is achieved by the following technical solutions, the present invention includes: metal base plate, first group of fork arm, initiatively voussoir, voussoir contact roller, voussoir chute, horizontal metal oil cylinder, crotch cross sliding clock, crotch slide block chute, slide block adapter shaft, second group of fork arm, passive insulation voussoir, the 3rd group of fork arm, insulation top board.Connection mode is: voussoir chute and crotch cross sliding clock chute all are fixed on the metal base plate, initiatively voussoir and crotch cross sliding clock can slide in the chute respectively separately, the horizontal metal cylinder tube is terminal hinged with metal base plate, piston end is with initiatively voussoir is hinged, the voussoir contact roller is hinged on its upper left corner with the active voussoir, the slide block adapter shaft is perpendicular to the active voussoir and pass take-over zone on the voussoir, passive insulation voussoir and second group of fork arm are fixed together, first group of fork arm is connected in the pivotally attached mode on one side with metal base plate, the other end is that piston shoes connect, and the 3rd group of fork arm is connected in the pivotally attached mode on one side with the insulation top board, and the other end is that piston shoes connect.
When beginning work, insulated elevating mechanism is in the state of regaining fully, and the piston of horizontal metal oil cylinder stretches out fully, and the slide block adapter shaft contacts with the forward position of voussoir take-over zone initiatively, and the wedge surface of passive insulation voussoir contacts with roller on the active voussoir.The oil-feed of horizontal metal cylinder rod chamber, initiatively voussoir is slided in the voussoir chute by horizontal metal oil cylinder level pulling beginning, being hinged on initiatively simultaneously, the voussoir upper roller promotes passive insulation voussoir, passive voussoir drives second group of fork arm whole crotch that begins to hoist, at this moment, also begin horizontal slip in crotch slide block chute passively with first group of fork arm pivotally attached crotch cross sliding clock.Because the speed of crotch cross sliding clock parallel motion is slower than the initiatively horizontal velocity of voussoir, rise along with insulated elevating mechanism, the slide block adapter shaft is back along contacting with active voussoir take-over zone, initiatively voussoir starts drag slide block adapter shaft parallel motion, and at this moment initiatively the roller on the voussoir begin to separate with passive insulation voussoir, finished the relay of driving.At last, initiatively voussoir pulling fork arm cross sliding clock adapter shaft is covered remaining stroke, makes insulated elevating mechanism be elevated to specified altitude assignment.
The present invention has substantive distinguishing features and marked improvement, simple in structure, in light weight, adopt horizontal metal oil cylinder and main passive voussoir alternate relay type of drive, not only guaranteed the High-Voltage Insulation performance of insulated elevating mechanism, reduce difficulty of processing and manufacturing cost, and reduced the propulsive effort of oil cylinder significantly, improved the stability and the reliability of insulated elevating mechanism.
