Specific implementation mode
The utility model technical solution claimed is done further specifically in conjunction with the drawings and specific embodiments
It is bright.
Shown in Fig. 1 to Fig. 2, the folded support of tunnel trolley that falls in the present embodiment includes body frame 1, for driving underbody
The mobile mechanism 2 of the movement of frame 1 is fixedly installed in two supporting racks 3 of 1 moving direction front and rear sides of body frame and for jacking
The jacking unit 4 of body frame 1, it is hand thread jack to jack unit 4 in the present embodiment.
In the present embodiment, mobile mechanism 2 includes the wheel 21 for being rotationally connected with body frame 1, driving belt 22, driving electricity
Machine 23, reduction box 24 and belt pulley 25, wherein driving motor 23 connect 24 input shaft of reduction box, and belt pulley 25 connects reduction box 24
Output shaft, driving belt 22 connect belt pulley 25 and wheel 21.When mobile, 24 output shaft of reduction box is driven by driving motor 23
Rotation makes folded fall to drive belt pulley 25 to rotate, eventually by gearing band 21 shaft of motor car wheel of driving belt 22 worn
Support of tunnel trolley moves in tunnel.
Each supporting rack 3 includes support frame body 31 and the multiple supporting mechanisms for being set to 31 periphery of support frame body
32, each supporting mechanism 32 includes the mounting base 321 being fixedly installed on support frame body 31, is used for top pressure tunnel duct piece
5 support element 322 and the top pressure unit 323 being connected between support element 322 and mounting base 321, in the present embodiment top pressure
Unit 323 is hydraulic jack and double end jack.
In the present embodiment, the domed structure in cross section of frame body 31, the support frame body 31 is supported to be welded by channel steel
It forms, and is welded with floor 311 in channel steel, floor 311 welds and simultaneously perpendicular to the two side of channel steel and bottom plate；Using
After above structure, support frame body 31 can reduce materials under the premise of holding structure is stablized and save into production cost, drop simultaneously
Its low weight falls the overall movement of support of tunnel trolley convenient for folded.In addition, support frame body 31 is welded by five sections of channel steels, including
It constitutes support 31 both sides of frame body and supports 31 top of frame body perpendicular to the side of body frame 1, composition and be parallel to body frame 1
Top margin and two be separately connected side and the corner side of top margin, welding group is carried out to support frame body 31 through the above way
It closes, the support frame body 31 compared to integral structure can reduce the production difficulty of support frame body 31 and reduce production cost.
Since the width machine height in tunnel is larger, in order to enable the section of jurisdiction 5 of the effectively top pressure tunnel inner wall of support element 322, supporting rack
The height of main body 31 and the development length of top pressure unit 323 are generally large, based on lever principle support frame body 31 and top
Pressure unit 323 is easier to occur swinging deviateing even to deform, in order to solve the above problem in the present embodiment, between two supporting racks 3
It is connected at least a pair of of tie-beam 33, and tripod 34 is connected between tie-beam 33 and two supporting racks 3, utilizes tie-beam 33
The folded structural stability for falling support of tunnel trolley entirety can be improved with tripod 34, prevent two bendings along the longitudinal direction of supporting rack 3
Deformation.Similarly, the present embodiment is also connected with connecting rod 35 between the support element 322 of two supporting racks 3, improves structural stability.
In the present embodiment, the folded operation principle for falling support of tunnel trolley is as follows：Folded in the present embodiment falls support of tunnel platform
Vehicle, the mobile mechanism 2 of body frame 1 can drive trolley whole and be moved to supporting point along tunnel, on the supporting rack 3 of both sides
It is that its support element 322 is avoided to rub with tunnel duct piece 5 in folded fall in support of tunnel trolley moving process with multiple supporting mechanisms 32
It wipes, top pressure unit 323 needs to shrink when moving.When it is folded fall the movement of support of tunnel trolley in place after, jacking unit 4 is by body frame 1
Jacking, which is lifted, to be made a reservation for up to the wheel 21 in its mobile mechanism 2 leaves ground to prevent from folding falling support of tunnel trolley and sliding to deviate
Supporting point, by jack in this present embodiment unit 4 be hand thread jack, by construction personnel operate jacking unit 4,
Be example jacking unit 4 quantity at least there are four and be arranged in 1 four jiaos of body frame, using jacking unit 4 to body frame 1
Also can leveling be carried out to body frame 1 by multiple jacking units 4 simultaneously when jacking.Jacking unit 4 also may be used in other embodiments
Equivalence replacement is hydraulic jack.After body frame 1 is lifted, the top pressure unit 323 of supporting mechanism 32 stretches out to drive branch
The section of jurisdiction 5 of 322 top pressure tunnel inner wall of support member is particularly applicable to fold to carry out reinforcing stabilization to supporting point inner tunnel structure
It falls in the tunnel of structure, folded will be fallen after the slip casting completion between uplink tunnel and downlink tunnel makes the stable structure of downlink tunnel
Support of tunnel trolley is removed from this.It is shown in Figure 3, in addition, in the present embodiment, being arranged in tunnel using more
It is folded to fall support of tunnel trolley section of jurisdiction 5 is supported, wherein each folded spacing fallen between support of tunnel trolley should be less than section of jurisdiction 5
Length with to making the section of jurisdiction 5 in its supporting zone that can be supported.
The embodiment of the above is only the preferred embodiment of the utility model, not does any form to the utility model
On limitation.Any technical person familiar with the field all can profit in the case where not departing from technical solutions of the utility model ambit
More possible variations and retouching are made to technical solutions of the utility model with the technology contents of the disclosure above, or are revised as equivalent
