As shown in Figure 5, the concrete structure of articulated section 5 is: hinged-support otic placode 502 is welded on L beam rear portion 501, hinged-support adapter sleeve 505 is welded on girder rear portion 503, the hinged-support otic placode 502 welded with L beam rear portion 501 and being connected with hinged-support pin 504 with both hinged-support adapter sleeves 505 that girder rear portion 503 has been welded, the outer flange dish of hinged-support pin 504 is fixed with bolt, and inner side is put locking plate 506 and is put on lock pin 507.
As shown in Figure 4, the hydraulic system structure of wind electricity blade mountain carrier vehicle of the present invention comprises: powerplant module 401, this powerplant module 401 mainly comprises the two fulcrum diesel motor 402 of ZH4100D, 30Kv electrical generator 403, Air compressor 405 and electric hydaulic station 404, electric hydaulic station comprises plunger pump, this plunger pump connects the multiple directional control valve 406 of electromagnetic control, the multiple directional control valve 406 of this electromagnetic control is divided into four tunnels, connect the support cylinder of 1. sweeps respectively, 2. under two of balance cock, reinstall rotation mechanism 407, 3. connect two elevating rams 409 containing balance cock by synchronous valve 408, 4. two upper dresses containing balance cock become oar swing type mechanism 410.Also comprise simultaneously in order to the hydraulic pressure solid drawn pipe of connecting components and high pressure consistent lubricant pipe 13 some.
The operating system of wind electricity blade mountain carrier vehicle of the present invention comprises: the service platform 10 being arranged on the second horizontal segment front end of girder 7, this service platform has operating handle 11, this operating handle has 3, for operating handle A, operating handle B, operating handle C, realizes becoming oar, lifting and revolution respectively by the multiple directional control valve handling electromagnetic control.And operating system also comprises wireless remote control handling device, can the switching of remote operation electromagnetic control multiple directional control valve by this wireless remote control handling device, add the safety of operative employee.
Owing to being followed successively by the first horizontal segment by girder 7 along its length L, tilting section and the second horizontal segment, and the height of the first horizontal surface is lower than the second horizontal surface, first horizontal segment is connected with the second horizontal segment by tilting section obliquely, after placing L beam turnover panel 2 like this on the first horizontal segment, the upper level of L beam turnover panel 2 is roughly consistent with the upper level of the second horizontal segment, be conducive to the steady placement of wind electricity blade like this, add safety, the existence of tilting section simultaneously, just for arranging the mounting groove installing elevating ram 6, elevating ram 6 is made to become concealed oil cylinder, oil cylinder operationally, its expansion link is positioned at the below of wind electricity blade, avoid it just to the both sides of blade, make large-sized, blade even wider than width over sides of car body also can be transported, hydraulic ram is being connected with L beam turnover panel V horizontal segment with vertical section connecting portion one end away from L beam turnover panel horizontal segment H, be different from the vertical section that expansion link in prior art is connected directly between L beam, thus flexible stroke is shortened dramatically, thus can stability be improve, add safety.When elevating ram 6 is slant setting simultaneously, can accomplish substantially vertical with tilting section, the vertical section height in conjunction with girder tilting section and the first horizontal segment and the second horizontal segment junction designs, and the structural strength in this portion is greatly strengthened, adds safety.
The setting of articulated section 5 of the present invention simultaneously, the relatively traditional frock fulcrum of hinged-support moves forward, as Fig. 1, shown in 5, be not positioned at immediately below L beam turnover panel vertical section V, but stand away, significantly increase with the distance of turnover panel counterweight 1, like this when lifting, due to lever principle, the weight of the turnover panel counterweight 1 of little weight is only needed to complete lifting, traditional frock transports 2.5 megawatt 45.3 meters, the wind electricity blade turnover panel of the wind electricity blade that weight is 10 tons needs counterweight 8 tons, the counterweight of hinged-support reach end blocking only needs 2 tons of counterweights, save the energy, simultaneously because balance weight reduces, also improve balance and safety.
For hydraulic efficiency pressure system, traditional Hydraulic Station moves axial axis plug pump by engine direct tape splicing, and the hydraulic power of output is controlled by the throttle size of driving engine, and the oil pressure thus exported is non-quantitative, thus the lifting of fan blade, revolution and change oar speed are indefinite, thus bring difficulty to transport.Adopt Novel hydraulic station to be that driving engine 402 drive electrical generators 403 generates electricity, drive motor provides hydraulic power by driven by motor axial axis plug pump, and this power is quantitative, thus makes the lifting of fan blade, revolution and change oar more stable.
The joystick of operating system is positioned at the front end of girder second horizontal segment, add the simplicity of operation, and be replaced with electromagnetic control multiple directional control valve 406 by the multiple directional control valve of traditional frock, Remote can be realized control, add the safety of operative employee, the hydraulic tubing of elevating ram 6 install synchronous, 408 and point combiner valve, synchronous valve-point combiner valve controls two/HM Hydraulic Motor in hydraulic synchronous system makes it keep synchronized. reinstall rotation mechanism, elevating ram 6, upper dress becomes oar swing type mechanism all with addition of balance cock, can prevent large chamber in-line rapid decompression from causing oil cylinder to decline, cause with preventing load inertia that oil return speed is too fast causes danger.Thus achieve the lifting stability of oil cylinder.
During work; start the engine is by driven by engine electrical power generators; then closed hydraulic motor earth leakage protective device; motor connects axial plunger pump provides hydraulic power, and plunger pump promotes hydraulic oil and enters hydraulic pressure solid drawn pipe, hydraulic pressure solid drawn pipe by high pressure consistent lubricant pipe connection electromagnetic control multiple directional control valve.
When carrying out left and right revolution operation, promote operating handle C, hydraulic oil is made to enter the high pressure consistent lubricant pipe of connection, the hydraulic pressure solid drawn pipe fixed is entered by hydraulic hose, at the end welding three-pronged connector of the seamless steel of hydraulic pressure, connected two swing type mechanisms of three-pronged connector and lower dress by high pressure consistent lubricant pipe, thus drive the left and right of whole frock to turn round.
When carrying out lift operation, promote the high pressure consistent lubricant pipe that operating handle B hydraulic oil enters connection, the hydraulic pressure solid drawn pipe fixed is entered by high pressure consistent lubricant pipe, synchronous valve is connected to high pressure consistent lubricant pipe again at the end of hydraulic pressure solid drawn pipe, between synchronous valve and elevating ram balance cock, there is high pressure consistent lubricant pipe 13 to connect, thus promote the flexible lifting realizing wind electricity blade of elevating ram.
When carrying out the operation of change oar, promote the high pressure consistent lubricant pipe that operating handle A hydraulic oil connects, entered the hydraulic pressure solid drawn pipe fixed by high pressure consistent lubricant pipe, be connected to two change oar swing type mechanisms of dress at the end high pressure consistent lubricant pipe of hydraulic pressure solid drawn pipe, thus realize the change oar of wind electricity blade.
