Flexible arm assembly 14 is using the heavy suit of four joint arms, the stretching structure of steel wire rope oiling cylinder, and this is common with the market
The engineering truck stretching structure of other type belt telescopic arms is as good as, and does not do excessive elaboration herein.
High-pressure sprayer is made up of water pump 6, water tank 1, connecting pipeline, water injector 7.The vertical shaft is drawn digging car water pump 6 and adopted
Import high-pressure plunger pump is used, is fetched water by carrying water tank 1, the water jet of height cumulative can be provided, mechanism 15 is grabbed along vertical shaft in grab bucket
Take it is various silt thing up, after preliminary dredging vertical shaft, sprayed water with high pressure by water injector 7, to reach to the thorough dredging of drainage pipeline networks
Purpose, water injector 7 is a sprinkler with water pipe reel and fountain head.
Can bending grab bucket mechanism include underground supporting arm mechanism, revolution driving component 1, grab bucket oscillating arm mechanisms, revolution drive
Dynamic component 2 210, grab bucket;Grab bucket is connected by revolution driving component 2 210 with grab bucket oscillating arm mechanisms, and grab bucket oscillating arm mechanisms pass through
Revolution driving component 1 is connected with underground supporting arm mechanism;
Underground supporting arm mechanism includes support arm and fixes forearm 21, support arm slip large arm 22, support bar component, support arm
Companding oil cylinder 23, it is a tubular construction part that support arm, which fixes forearm 21, is taken, lower shoe couples ear with various, and its upper plate leads to
Cross bolt and vertical shaft and draw the lower shoe of digging car telescopic arm 215 and couple, lower shoe couples with revolution driving component 1;Support arm is slided
Large arm 22 is also a tubular construction part, is set in support arm and fixes on forearm 21, take, second line of a couplet lug, ear and branch are coupled thereon
The rod head end of brace companding oil cylinder 23 is by hinge, and the ear that couples that second line of a couplet lug is fixed on forearm 21 with support arm passes through bearing pin
It is hinged;Support bar component is made up of two hinge bars 24 and borehole wall wedge 25, and the one end of two hinge bar 24 fixes small with support arm respectively
Arm 21, support arm slide large arm 22 by hinge, and the other end is hinged with borehole wall wedge 25, and the digging car course of work is drawn in vertical shaft
In, telescopic arm 215 is stretched, and underground supporting arm mechanism enters in vertical shaft, and the piston rod of support arm companding oil cylinder 23 is acted in pressure oil
It is lower to retract, drive the action of support bar component, borehole wall wedge 25 just can reliablely and stablely fit the borehole wall, further draw digging for grab bucket and carry
For rigid support.
Revolution driving component 1 is a turbine and worm drive pair, and the support arm that it couples underground supporting arm mechanism fixes small
Arm 21 and the pedestal 27 of grab bucket oscillating arm mechanisms.
Grab bucket oscillating arm mechanisms are made up of pedestal 27, swing arm 28, swing arm oil cylinder 29, swing arm 28 and pedestal 27, swing arm oil cylinder 29
With pedestal 27, swing arm oil cylinder 29 with swing arm 28 by hinge, flexible by the piston rod of swing arm oil cylinder 29 just can be realized
90 degree of swings of swing arm, the lower end of swing arm 28 separately carries hinge hole, coupled by bearing pin with revolution driving component 2 210.
Revolution driving component 2 210 is a rotation motor, and the lower end output shaft of rotation motor passes through key and bucket folding oil
The cylinder tube base connection of cylinder 211.
Grab bucket is made up of left and right grab bucket 213, bucket folding oil cylinder 211, grab bucket connecting rod 212, contiguous block 214, left and right
Grab bucket 213, grab bucket connecting rod 212 have two connection ears;The cylinder tube base band two of bucket folding oil cylinder 211 couple ear, respectively with
The first line of a couplet lug of connecting rod 212 grab bucket by hinge, the grab bucket second line of a couplet lug of connecting rod 212 is hinged with left and right grab bucket 213;Left,
The right another connection ear of grab bucket 213 is hinged with contiguous block 214;Contiguous block 214 is relatively fixed with the piston rod of bucket folding oil cylinder 211 again
Connection;So, the piston rod of bucket folding oil cylinder 211 is flexible just can drive the folding of left and right grab bucket 213, crawl to silt thing up.
The vertical shaft of the present invention draws digging car in the course of the work, and the piston rod of underground supporting arm mechanism support arm companding oil cylinder 23 exists
Pressure oil effect is lower to be retracted, and drives the action of support bar component, and borehole wall wedge 25 is reliablely and stablely fitted the borehole wall, while swing arm oil cylinder
29 piston rods are retracted, and swing arm 8 can be put into vertical shaft vertical direction into an angle of 90 degrees, and revolution driving component 2 210 rotates this moment, bucket
The piston rod of folding oil cylinder 211 stretches, so just easily realize by it is vertical with vertical shaft and communicate, close treat the certain model of desilting vertical shaft
Underground pipe network in enclosing silts thing crawl, the purpose of dredging up, and then reaches to vertical shaft progress desilting comprehensive, without dead angle.Should
Vertical shaft is substantially increased with the grab bucket mechanism draw and dig the vertical shaft of car and draw digging scope and operating efficiency.Simultaneously because the type vertical shaft draws digging
Car itself is integrated with high-pressure sprayer, without the dredging vehicle water spray that please separately be sprayed water with high pressure again after conventional vertical shaft grab trolley draws digging
Thoroughly dredging, this just greatlys save construction cost, significantly improves operating efficiency and dredging effect.The invention, simple in construction,
It is safe and efficient.
Above is having carried out exemplary description to the present invention, it is clear that realization of the invention is not limited by aforesaid way
System, if the various improvement of technical solution of the present invention progress are employed, or it is not improved by the design of the present invention and technical scheme
Other occasions are directly applied to, within the scope of the present invention.
