The direction of rotation driven when rotary drive mechanism 8 is shunk.It is described outer in order to preferably reduce the resistance that lifting rope 9 is subject to
Boom 61 and the ipsilateral side lower end of first pulley 624 are provided with second pulley 611.In the present embodiment, lifting rope folding and unfolding driving machine
Structure 91 is hoist engine.Boom 6 cooperates lifting rope 9 and hoist engine can be by stand again under the action of rotary drive mechanism 8 in fact
It send from 1 side-lower of pedestal to stand carrying trolley, the second telescoping drive mechanism 7 is intended merely to stand, and that alignment is more easily adjusted is vertical
Frame, which carries trolley and receives when boom 6, is stacked in the non-bulging pedestal 1 of boom 6 when not in use of pedestal 1, hides on the pedestal 1.
Above-mentioned transverse direction is that guide rail puts extending direction, the i.e. left and right directions at the visual angle Fig. 2, and vertical is the upper and lower at the visual angle Fig. 4
To, and it is vertically vertical with transverse direction and plummet direction, plummet direction goes up and down direction.In the present embodiment, the stand carries trolley 3
Moving direction, the telescopic direction of scaling platform 4, the glide direction of lifting body 5 be transverse direction.
The present apparatus is automation control, the power such as above-mentioned all driving mechanisms, hoist engine, oil cylinder, hydraulic wireline winch, cord holder
Device is all connected with control system, and control system controls the work of entire machine by control power device.
The working principle of the present apparatus:
When present apparatus job initiation state, stand carries trolley 3 in position as shown in Figure 2, positioned at the left end of guide rail 2, rotation
Turning driving mechanism 8 is contraction state, and boom 6, which is also received, to be folded on the pedestal 1, and boom 6 is almost parallel to the horizontal plane, the second flexible driving
Mechanism 7 is elongation state, so that 6 top of boom exceeds pedestal 1 and guide rail 2, stand bind is on lifting rope 9, with rear lifting rope folding and unfolding
Driving mechanism 91 drives lifting rope 9 to shrink, and stand is raised to certain altitude, subsequent rotary drive mechanism 8 starts to extend, props up and hang
Arm 6, boom 6 drives stand to rotate to 1 top of pedestal, while the second telescoping drive mechanism 7 also starts to shrink, in rotary driving machine
Under the action of structure 8 and the second telescoping drive mechanism 7, make stand alignment stand carrying trolley 3, then lifting rope folding and unfolding driving mechanism 91
Start to put rope, drops to stand on stand carrying trolley 3, subsequent rotary drive mechanism 8 and the second telescoping drive mechanism 7 are multiple
Position, boom 6, which is received, to be folded on the pedestal 1.Subsequent stand carrying trolley 3 drives stand to move right.Until stand is moved to and is in back
Until the top of the lifting body 5 of contracting state, subsequent lifting body 5 is motionless, and scaling platform 4 stretches out, support cylinder 41 and support
Leg 42 is strutted with support telescopic platform 4.Then jacking clamping plate 51 rises certain distance, has accepted top positioned at stand and has carried trolley
Stand on 3, after stand is detached from the limitation of stand carrying trolley 3, lifting body 5 is whole to move right until to designated mounting
Until position, jacking clamping plate 51 is begun to ramp up, and stand is jacked to tunnel inner wall, and subsequent artificial station opposes in scaling platform 4
Frame carries out installation fixation.
The above embodiments are merely illustrative of the technical solutions of the present invention and is not intended to limit it, all without departing from the present invention
Any modification of spirit and scope or equivalent replacement, shall fall within the scope of the technical solution of the present invention.
