Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
The embodiment of the present invention: preliminary bracing stand operates trolley after a kind of tunnel tunnel face excavates, such as attached drawing 1-3 institute
Show, include car body, car body rear is provided with arch support and erects mechanism, and it includes to be arranged in car body that arch support, which erects mechanism,
Cushion cap 12 on rear frame 19, cushion cap 12 are connect through rotating disc 3 with 18 bottom of mounting platform, the cushion cap on 3 side of rotating disc
Hydraulic drive oil cylinder 13 is additionally provided on 12,18 upper surface of mounting platform is provided with multiple bracing members 15, mounting platform 18 or so
Two end faces, which are provided with, collapses hydraulic cylinder 8, collapses 8 head end of hydraulic cylinder and connect with operating platform 7,7 upper surface of operating platform
It is provided with hydraulic lift(ing) cylinder 6,7 bottom surface of operating platform is connect through connector with manual operation platform 5,5 bottom of manual operation platform
Plate is provided with rotatable hydraulic cylinder 4.
The present invention loads arch in use, first opening trolley to steel bar meter room, and arch is placed on arch support frame
At the top of vertical mechanism, arch bottom is resisted by bracing members 15.Then the trolley for being mounted with arch is opened in tunnel, passes through and excavates
It reverses end for end, parks at face after trolley, then arch support erects mechanism and starts to work.Firstly, rotating disc 3 acts on, drive
The mounting platform 18 being attached thereto rotates 90 degree, while the arch being located on bracing members 15 on mounting platform 18 and then rotates together
90 degree.Then hydraulic drive oil cylinder 13 is started to work, and releases jack up mounting platform 18 upwards upwards, so that itself and rotating disc 3
Separation then reels the work of hydraulic cylinder 8, is pushed outwardly so that operating platform 7 is separated with mounting platform 18, release is apart from basis
The push rod of hydraulic lift(ing) cylinder 6 and the contacting points position of arch bottom determine.After operating platform 7 is released, firstly, can be rotated hydraulic
Oil cylinder 4 deflects down after 90s, so that its push rod head end is perpendicular to the ground, then hydraulic cylinder 4 is extended downwardly, until its push rod cup
Until end resists ground, then hydraulic lift(ing) cylinder 6 works, and pushes up out so that it is contacted with arch bottom, and is continued up
It lifts arch and is pushed to installation position.Worker can stand at operating platform 7 and manual operation platform 5 and encircle at this time
The connection work of frame and the work of grouting small pilot pipe and armature boring.The surface layer steel plate of operating platform 7 is thickness 4mm decorative pattern
Steel plate prevents worker from skidding in construction operation injury.Right side and two Pin of middle part are first found in arch Bracing Process, then stand a left side again
Side.In whole process, when horizontal supporting position needs to adjust, it can be carried out by the movement of trolley and/or gathering hydraulic cylinder 8
Adjustment, and when the supporting position of vertical direction needs to adjust can pass through the dynamic of hydraulic drive oil cylinder 13 and/hydraulic lift(ing) cylinder 6
It is adjusted.Ground can be passed to by rotatable hydraulic cylinder 4 from the gravity of Bracing Process middle arch rack, prevented due to stand
When the vertical stress that generates cross ambassador's operating platform 7 and generate moment of flexure deformation.After completing once supporting, all parts recycling is multiple
Position, can carry out support work next time.
The car body back is provided with hydraulic push cylinder 11, the push rod of hydraulic push cylinder 11 be located at rear vehicle vehicle
Cushion cap 12 on frame 19 connects.Cushion cap 12 can be driven to move horizontally along vehicle frame 19 in hydraulic 11 course of work of push cylinder, held
Entire arch support can be driven to erect mechanism movement in 12 moving process of platform, arch can be carried out by hydraulic push cylinder 11
Support erects the adjustment of mechanism horizontal position.
The cushion cap 12 is internally provided with axis 9, and axis 9 is connect after passing through rotating disc 3 with 18 bottom of mounting platform.In this
9 bottom of axis is fixedly connected with cushion cap 12, and top is fixedly connected with 18 bottom of mounting platform, which divides can be pressed for 3 sections
Contracting and stretching.18 bottom of mounting platform is provided with wedging position corresponding with rotating disc 3, after entire support work combines,
Downlink under the action of hydraulic drive oil cylinder 13 of mounting platform 18, when the top of rotating disc 3 is caught in the card of 18 bottom of mounting platform
Behind socket part position, mounting platform 18 can just be driven to rotate, and being provided with axis 9 is exactly in order to avoid mounting platform 18 moves up and down
After positional shift occurs in the process, wedging position and 3 position of rotating disc be not corresponding, and it is flat to be just unable to drive installation for rotating disc 3 at this time
Platform 18 resets.
12 bottom of cushion cap is provided with traveling wheel 1, and traveling wheel 1 is located in sliding rail 2,.Sliding rail 2 is arranged
On vehicle frame 19, sliding rail 2 is made with channel steel, is erected on the crossbeam of vehicle frame 19, in the work of hydraulic push cylinder 11
Under, cushion cap 12 can be quickly driven to move back and forth along sliding rail 2.
The 19 rear end bottom of vehicle frame is provided with anti-suffix hydraulic 14, prevents after trolley top starts construction, top pressure
Power is conducted downwards, and vehicle body is made to generate bias at rear-wheel.
5 bottom of manual operation platform is provided with limit plate 16, which is mainly used for preventing rotatably hydraulic
Oil cylinder 4 shifts after working.
It is provided with baffle 17 at the top of the car body head end, which mainly avoids when trolley stops, and arch is used
Property effect under continue to move along.
The manual operation platform 5 is scalable platform comprising has the fixed plate connecting with connector, fixed plate bottom
More external steel pipes 501 are provided with, external steel pipe 501 is internally provided with internal steel pipe 502, and internal steel pipe 502 extend out to outside
Compressible steel mesh 20 is provided between head end and fixed plate outside steel pipe 501.
In arch Bracing Process, internal steel pipe 503 is pulled out from external steel pipe 502, so that entire manual operation platform 5
It is elongated, while compressible steel mesh 20 is stretched, and work standing is facilitated to be operated on it.It, will be internal after supporting
Steel pipe 503, which is pushed into, may make the volume for reducing manual operation platform 5 in external steel pipe 502, facilitate the discrepancy of trolley.
Compressible steel mesh 20 is connected between the mounting platform 18 and operating platform 7.It is released when collapsing hydraulic cylinder 8
After operating platform 7 is separated with mounting platform 18, compressible steel mesh 20 is stretched, formation operation platform 7 and mounting platform 18
Between intermediate zone, facilitate worker to walk between two platforms.Prevent top weight from falling to hydraulic destruction simultaneously.
6 bottom of hydraulic lift(ing) cylinder is provided with pulley 10, and pulley 10 is caught in the sliding slot on 7 surface of operating platform, can
Lift cylinder 6 is driven to be moved by pulley 10, to realize the adjustment of 6 scaffold position of lift cylinder.
