The maximum pushing distance on top 20, which is greater than, elapses the length of the pedestal 1 on direction at it.Pushing beam plays the entire hydraulic prop of balance
Distribution of weight effect, meanwhile, in the entire hydraulic prop of movement, it is only necessary to start advancing jack, shift entire hydraulic branch onto
River bottom protection seat moves a pedestal distance, is located in supporting channel after making hydraulic prop sidesway, then passes through advancing jack again
It shrinks, so that pushing beam 10 is playbacked, convenient for shifting to entire hydraulic prop.
Meanwhile in order to keep entire hydraulic prop more firm, in another lateral location of the pedestal 1 opposite with pushing beam 10
Equipped with overturn-preventing pedestal 30, overturn-preventing pedestal 30 and pedestal 1 form rotation by shaft 40 and connect, and pedestal 1, which is equipped with, folds thousand
Jin top 50, one end and the overturn-preventing pedestal 30 for folding jack 50 are hinged；When folding the elongation of jack 50, overturn-preventing pedestal is pushed
30 gradually rotate to same plane is in pedestal 1, effectively increase the contact area of original pedestal, overturn-preventing pedestal 30 increases
River bottom protection area is beneficial to control Floor Heave in Roadway phenomenon；When folding the contraction of jack 50, pull overturn-preventing pedestal 30 gradually upward
Rotation in vertical state, is readily transported to pedestal 1, reduces the occupied area of entire hydraulic prop.
First driving device 8 employed in the present invention can be the first overturning jack 82, the first overturning jack 82
Both ends it is hinged with long backplate 6 and top beam 2 respectively, it is flexible that long backplate 6 can be driven to overturn relative to top beam 2.
First driving device can also include first connecting rod mechanism 81 and the first overturning jack 82, the first overturning jack
81 are horizontally placed on the lower end of top beam 2；First connecting rod mechanism 81 includes first connecting rod a811 and first connecting rod b812, first connecting rod
It is formed hingedly between one end and first connecting rod b812 of a811 by first rotating shaft 60, the other end and top beam 2 of first connecting rod a811
It is hinged, it is hinged that the both ends first connecting rod b812 form rotation with long backplate 6 and the first overturning jack 82 respectively.
Certainly, the present invention in order to carry out effective support to tunnel two sides, cut with scissors by a side of long backplate 6 and the side of top beam
It connects, a folding backplate 70 is also set up at another relative side, fold backplate 70 and long backplate 6 by articulated shaft 80 and form rotation
Connection is additionally provided with the second driving device 90 on long backplate 6, and the second driving device 90 is connect with backplate 70 is folded, for driving
It folds backplate 70 to rotate along articulated shaft 80, converts folding backplate 70 between stretching out and folding two states.Fold backplate and
The effective support to tunnel two sides may be implemented in short backplate, and supporting range is wider.
As shown in Figure 4 and Figure 5, the second driving device 90 employed in the present invention includes second connecting rod mechanism 901 and the
Two overturning jack 902, the second overturning jack 902 are set to the abdomen of long backplate 6；Second connecting rod mechanism includes second connecting rod
One end of a9011 and second connecting rod b9012, second connecting rod a9011 and one end of second connecting rod b are formed by the second shaft 100
Hingedly, the other end of second connecting rod a9011 is hinged with long backplate 6, the other end and folding 70 phase of backplate of second connecting rod b9012
Hingedly, it is hinged to form rotation for one end of the second overturning jack 902 and the second shaft 100.Pass through the second overturning jack 902
Expanding-contracting action pushes or pull on the movement of the second shaft 100, under the guiding role of second connecting rod a and second connecting rod b, realization pair
Fold the overturning control of backplate.
As shown in fig. 6, the hydraulic prop size according to the span length production present invention, it is each very heavy to pass sequentially through driving
Work is pushed, realizes the rising of top beam, the expansion of overturn-preventing pedestal, the expansion of long backplate and short backplate, and fold the exhibition of backplate
It opens, realizes the top on span length direction and two sides protection.
As shown in fig. 7, when needing to shift a certain hydraulic prop therein, it is only necessary to each jack is driven,
Each backplate is folded, and top beam is minimized into position, finally by driving advancing jack, pushing beam is supported on tunnel side
On wall, the pedestal of hydraulic prop is set to offset out a position base under the thrust of advancing jack, to be shifted
It to the other side in tunnel, then passes through passageway and hydraulic prop is moved to the position for needing to carry out supporting, finally again by each shield
Plate and the expansion of overturn-preventing pedestal carry out roadway support.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
