Principle of work:
1, base and rail is fixing: when needing rail in the wild operates, the present invention is moved on rail, rail wheel is placed on rail, downward moulded rod 801, push rod 804 is at the moved downward of depression bar, and to being in two connecting rods 806 of upper crossing condition to depressing to horizontality, two the rail clips 808 making original bottom be in open configuration inwardly shrink, two rail clip 808 bottoms draw-in groove clamp rail from both sides, base is fixed on rail.
2, lift support frame group: on the first order treadle of operator station on the ground or on end bracing frame, with the top joystick 3044 on hand dynamic middle bracing frame 202, top joystick rotates the worm screw in the top worm and gear of corresponding connection, due to two top worm and gears pay in worm screw be link together by pushing up horizontal dwang, like this another top worm and gear pay in top worm gear and top worm screw also synchronously together with rotate, two top worm gears also drive two top transit levers 315 to rotate together respectively simultaneously, so four top rope reel 317 synchronous axial system, top rope 302 just pulls topmast support 201 vertically to rise along middle bracing frame 202, after being raised to position, switching topmast support block 313, hold the bottom of topmast support 201, rise rear downslide to prevent topmast support 201 and rope is unloaded, staff is with joystick 3084 on bracing frame of the hand dynamic end, in like manner also middle bracing frame 202 is pulled vertically to rise along end bracing frame 203 by middle rope 306, after being raised to position, bracing frame block 310 in switching, hold the bottom of middle bracing frame 202, rise rear downslide to prevent middle bracing frame 202 and topmast support 201 and rope is unloaded.
3, decent support group: first according to the order reverse operating of step 2, successively middle bracing frame and topmast support are dropped to the end, more front guardrail 102, rear guardrail 103, right guardrail 104 and left guardrail 101 are knocked down be successively folded on job platform.
4, base unclamps: according to the order reverse operating of step 1, lift depression bar and unclamp track locking device, just the present invention can be moved away from rail or highway setting.
5, auxiliary straignt line guide rail: operate according to step 2, step 3, the rising of topmast support 201 and middle bracing frame 202 and decline are also subject to the constraint of pushing up auxiliary straignt line guide rail 701 and middle auxiliary straignt line guide rail 702, and rising and the decline of such topmast support 201 and middle bracing frame 202 are just more reliable and more stable.
6, carry out fast at the scene dismantling and assembling: because the present invention adopts various latch in a large number, so between job platform and topmast support, between the end bracing frame of the right and left, between the topmast support of the right and left, undertaken connecting or dismantling by multiple latch, pull bar, cross bar respectively between the four rolling support of base, job platform, the supporting frame group on the left side, the supporting frame group on the right and base is made to realize being separated and assembling, be easy to carry and carry, thus can carry out fast at the scene dismantling and assembling.
7, the emergency state: as emergency situation met by railway, because the present invention does not have electrical motor or the heavy wares such as hydraulic ram or other power plant, lighter in weight, manual shake rocking bar just can decent support group drawing in, several staff just the present invention conveniently setting be need only can be moved apart, unnecessary economic loss and personal casualty avoided.
8, the dismounting of base and assembling: the outer end of base sheath tubular axis 401 is outwards inserted between lock tube 402 and roller shaft 411, in roller shaft latch 406 two ends inserted base quill drive open slot 409 in after, base sheath tubular axis rotates 30 degree, in roller shaft, latch enters the bottom of the open slot 409 of base sheath tubular axis " L " shape, the outer end of base sheath tubular axis 401 is made to entangle the roller shaft 411 of the right and left respectively from the right and left, then lock tube 402 moves inward a segment distance, lock tube inner opening groove 408 enters latch 406 position on base sheath tubular axis, lock tube pin 407 snaps in base sheath tubular axis open slot 409 simultaneously, such base sheath tubular axis 401 can not rotate, base sheath tubular axis 401 and roller shaft 411 are also just fixed together by lock tube 402, by above-mentioned steps reverse operation during dismounting, just base sheath tubular axis can be spun off from lock tube, realize being separated of base sheath tubular axis and roller shaft, also just achieve the separation of the right and left supporting frame group.
