Overturn-preventing pedestal 5 combines, and when there is bump, effectively prevent toppling over for entire protective stent, with flush-prevention function
Side guard plate 4 can effectively stop side portion's bastard coal to pour in tunnel, avoid tunnel that blocking suddenly occurs, escape danger to rescue work and personnel and strive
The more time is taken.Hydraulic vertical prop 2 therein includes vertical hydraulic cylinder body 21 and piston rod 22, and the lower end of hydraulic cylinder 21 is fixed
In on pedestal 1, the end of piston rod 22 and the lower end of top beam 3 form a fixed connection, and drive piston rod 22 by hydraulic cylinder 21
It is moved up and down with top beam realization.
As shown in Fig. 2, the erosion control device 7 with energy-absorbing protective action is additionally provided between side guard plate 4 and guiding device 6, side shield
One end of plate 4 and pedestal 1 are in be vertically arranged on pedestal 1 after being formed hingedly.
In order to adjust reasonable working condition when 4 wall supporting of side guard plate, shield is additionally provided between side guard plate 4 and guiding device 6
Jack 8 is helped, wall supporting jack 8 is set to the lower section of erosion control device 7, certainly can also be as the case may be by wall supporting jack 8
It is set to the top position of erosion control device 7.According to the plate face size and shape of side guard plate, erosion control device 7 is placed in optimal buffering position
It sets, the both ends of wall supporting jack 8 here are hinged with the lateral surface of side guard plate 4 and sleeve 61 respectively, for adjusting erosion control device 7
To best operational position.Side guard plate 4 is preferably that cross section is rectangular box structure, is articulated and connected between side guard plate 4 and pedestal 1, side
Backplate 4 can be 1-2 part, so that 8 one end of wall supporting jack and side guard plate 4 are hinged, the other end and pedestal 1 are hinged, shield here
Helping jack 8 can be 1-2 part.It is preferably that the protection of side guard plate 4 is wide in order to further increase the protection effect of side guard plate 4
Degree is set greater than the lateral surface equal to two hydraulic vertical props 2 and is formed by spacing.
In order to avoid the former retaining portion such as anchor pole (rope), the present invention is also provided with sliding beam 40, sliding in the upper end of top beam
The width of beam 40 is no more than the width of top beam 3, and is additionally provided at least one long slot hole 401 in the upper surface position of sliding beam 40,
As shown in Figure 3；An advancing jack 50 is fixed on top beam 3, advancing jack 50 and sliding beam 40, which are formed, to be drivingly connected, for driving
Dynamic sliding beam 40 is moved along the width direction of top beam 3, and realization can avoid anchor pole (rope) function, will not cause to former supporting any
Damage.Here 50 one end of advancing jack and top beam 3 are using directly or indirectly fixed, and the other end is directly or indirectly and sliding beam
Fixed, advancing jack 50 is flexible to drive sliding beam 40 to horizontally slip on top beam 3, and sliding beam 40 can be 1-2 sections, passage thousand
Jin top 50 can be 1-4 root, and when advancing jack 50 is more, part jack can be replaced by guide rod.Sliding beam 40
Length is less than or equal to the length of top beam 3.It is, of course, also possible to sliding beam is moved along the length direction of top beam 3, need at this time by
Advancing jack is arranged on another side, the width of the length of sliding beam and top beam can be consistent, very heavy elapsing
It is moved forward and backward under the traction on top along top beam length direction, avoids the anchor pole (rope) on former branch mask.
Certainly, the adjacent two advanced hydraulic prop of front and back placement position is connected for convenience, the present invention is also pushing up
The both ends of beam 3 be equipped with frame between can bindiny mechanism 60, for the concatenation between adjacent two tunnels advanced hydraulic support top beam 3；Also the bottom of at
1 both ends of seat are equipped with connecting mechanism 60, for the concatenation between adjacent two tunnels advanced hydraulic support pedestal 1.
Energy-absorbing erosion control device employed in the present invention with flush-prevention function, the direction that can be pressed according to impact, will prevent
It rushes device and is mounted on different positions.Erosion control device can be mounted on bottom (top) end of hydraulic cylinder by the present invention, for absorbing top bottom
The energy that plate impacts to press, while erosion control device being installed also between side guard plate and guiding device, it is pressed for absorbing lateral wall impact
Energy.The erosion control device quantity for being mounted on hydraulic cylinder top or bottom end can be 2-4 part, be mounted on side guard plate and guiding device
Between erosion control device quantity can be 1-2 part, erosion control device here is the prior art, can be using the suction with deformation protecting against shock
It can structure.
By increasing the sliding beam part that can avoid anchor pole (rope) in common lame advanced supporting part, anti-side side impacts
