As it is shown in figure 1, described track installation in concrete tunnel 5 on two inwalls of length direction, mixed
Orbital Symmetry on two inwalls in solidifying heatable adobe sleeping platform road 5 is arranged, the two ends of described middle cover plate lay respectively at phase
Answer on rhombus elevating mechanism 7, the corresponding corresponding track of the pulley at each middle cover plate two ends；Described rhombus
Elevating mechanism 7 is adjacent with guide rail；When inter panel block is even number and also be to divide the left and right sides equally to move, described
The number of track is identical with the number of middle cover plate, divides equally carry out to from left to right because inter panel is left and right
Slide, so the track number on the concrete tunnel of the same side should be the half of the number of inter panel.
As shown in Figure 4 and Figure 5, the installing hole on middle cover plate is arranged according to the moving direction of this cover plate block
In different parts, described middle cover plate includes LC cover plate and right central cover, LC cover plate
Block to slide to the left, so installing hole thereon is arranged on the two ends of cover plate block left part, and right central cover block
To slide to the right, so installing hole thereon is arranged on the two ends of cover plate block right part.
As shown in Figure 1 and Figure 5, in order to be able to make a left end cap plate and two left cap plates and one
Right end cap plate and two right cap plates stack downwards, and two ends, long track left and right are respectively provided with short track, short
Track is collapsible with long track, and the track number on short track is identical with the track number on long track；Initially
During state, short track folds on long track, and the short track in a described left side is positioned at the lower section of described left cap plate,
The short track in the described right side is positioned at the lower section of described right cap plate；When mobile middle cover plate, by short track from
Launching on long track, the short track after expansion is laid on second piece of left cap plate of heap poststack, in like manner launches
After the short track in the right side be laid on second piece of right cap plate of heap poststack, after overhauling, then work as middle cover
After plate tiling resets, by short track refolding to long track, the most again by multiple for the tiling of remaining cover plate block
Position.
As shown in Figure 5 and Figure 6, the drive link 82 of described drive mechanism 9 is when rhombus elevating mechanism 2 is according to phase
When answering middle cover plate desired height to rise, can disassemble from inter panel block.
As it is shown in fig. 7, the other end of described elevating lever 42 is connected with lifting supporting plate, described lifting supporting plate is positioned at
The bottom of described right end cap plate；The other end of described elevating lever 42 is through described fluting and described right end cover plate
Connection can be fixed in the bottom of block, it is possible to does not fixes；Base 44 and the axis of rolling are passed through in the lower end of described leading screw 43
Holding on the outer wall being arranged on concrete tunnel 8, rolling bearing is arranged in base 44, the lower end of leading screw 43
With rolling bearing interference fit.By manual rotation's handwheel, handle screw mechanism and make the end cover plate at two ends
Down or up one layer, the height of a layer is the height of a cover plate block, then moves adjacent left side cover plate
Block or right cap plate are to moving at the beginning of centre on the end cover plate at two ends or by the inter panel at two ends
Beginning position, is rotated further by handwheel and is allowed to down or up one layer, so operation the most just can by left cap plate,
Right cap plate, middle cover plate are quickly opened or close.
The work process of the present invention is: the initial condition of whole mechanism is that cover plate 2 is laid on concrete tunnel,
When needing to overhaul the pipeline in concrete tunnel 5, then drive leading screw 43, nut by rotation handwheel 41
Elevating lever 42 is driven to make the end cover plate at two ends decline one layer, then by adjacent left cap plate and right side
Cover plate block shifts left end and right-hand member end respectively onto, the most in triplicate, is just all stacked by the cover plate block down stacked
Good, the wheel support 3 of middle four pieces of middle cover plates is folded in (cover plate tiling below middle cover plate
Time), both sides top cover lath 8 is taken out, external impetus mechanism is by driving the drive mechanism at cover plate 2 two ends
The rotation of 9, drives bevel gear 81 to engage with drive bevel gear 21, passes motion to by bevel gear engagement
Screw pair on rhombus elevating mechanism 7, the nut 22 on screw mandrel 24 moves to the left or right, so that rhombus
Elevating mechanism 7 rises, and by middle cover plate jack-up, will be folded in the wheel support 3 bottom middle cover plate
Strut so that it is the roller of end contacts with folding track 6, by middle cover plate by the way of people tries hard to recommend
The one end shifting concrete tunnel 7 onto stacks, and the mode stacked stacks to both sides from centre, due to wheel support 3
Length lengthen successively to centre from two ends so that middle cover plate can stack from level to level, repeats this
Action, until the left and right sides has six pieces of cover plate blocks respectively, wherein six pieces of cover plate blocks comprise two pieces of inter panels
Block, thus quickly can open cover plate 2；After maintenance, the middle cover plate that both sides are stacked
Shift middle position onto, make rhombus elevating mechanism 7 rise, support whole middle cover plate, then will
Wheel support 3 folds into the bottom of middle cover plate, falls rhombus elevating mechanism 7, is pacified by top cover lath 8
Putting, such four pieces of middle cover plates just place；Then the liter on screw mechanism is made by shake handwheel
Fall bar 42 rises one layer, shifts left cap plate or the right cap plate of stacking onto phase by the way of people tries hard to recommend
The position answered, repeats This move, until all of cover plate block is all laid complete, thus achieves well lid
The quickly opening and closing of plate.
The present invention considers surface vegetation (or concrete road surface) is fabricated to cover plate block one by one, is laid in
The top of pipeline, when need repairing pipeline time, just can easily one piece of block cover plate be folded by the present invention
Coming, after maintenance, then tiling is built, and recovers surface vegetation or concrete road surface, and whole work process is used
Time be greatly shortened, and greatly reduce maintenance cost, be a kind of sustainable development, application prospect is huge.
