The second end of grade face guard 1.Connecting rod 39 and connecting rod 4 10 are all provided between every two articulated slab 2 18.Each connecting rod 39
First end be all hinged on level-one face guard 1, the first end of each connecting rod 4 10 is all hinged on secondary protecting side plate 2；Each
The second end of connecting rod 39, the second end of each connecting rod 4 10 are all hinged with the mandril end of a secondary protecting side plate jack 8；Often
The second end of a secondary protecting side plate jack 8 is hinged on level-one face guard 1.
Side protecting mechanism further includes three-stage side protecting mechanism, and three-stage side protecting mechanism includes three-level expansion box 3 and three-level expansion box thousand
Jin top 11.Three-level expansion box 3 is slidably located in the surface of secondary protecting side plate 2, forms drawer-type structure；Three-level expansion box jack
11 first end is hinged on secondary protecting side plate 2, and the end of three-level expansion box 3 is fixedly connected with hinged ear 16, three-level expansion box
The second end of jack 11 is hinged by hinged ear 16 and three-level expansion box 3.When three-level expansion box 3 is stretched out or is withdrawn, second level
Face guard 2 plays the role of guiding.
By articulated connection, overall structure is simple for level-one face guard 1, secondary protecting side plate 2 and three-level expansion box 3, dismounting
It is convenient, it is easy to operate, wall supporting and gear cash can be played the role of simultaneously.
Under the action of level-one face guard jack 5, connecting rod 1 and connecting rod 27 is driven to act, so that level-one face guard 1
Rotation；Under the action of secondary protecting side plate jack 8, connecting rod 39 and connecting rod 4 10 is driven to act, so that 2 turns of secondary protecting side plate
It is dynamic.The stability rotated under this mode is good, and adjusting range is big, and support force is big.
As shown in connection with fig. 7, in the two sides preformed hole of level-one face guard 1, part 12 is bolted and level-one face guard is anti-
Sheath band 13 connects, and level-one face guard protects the level-one face guard of belt 13 and another adjacent hydraulic support protection belt 13 to realize
Overlap joint, realizes the closing and protection in gap between adjacent hydraulic support.
The fixed hanging block 19 of bolt is reserved in the two sides of secondary protecting side plate 2, part 12 is bolted and secondary protecting side plate is anti-
Sheath band 14 connects, and secondary protecting side plate protects the secondary protecting side plate of belt 14 and another adjacent hydraulic support protection belt 14 to realize
Overlap joint realizes the closing and protection in gap between adjacent hydraulic support.
In the two sides preformed hole of three-level expansion box 3, part 12 is bolted and is connect with three-level expansion box protection belt 15,
Three-level expansion box protects the three-level expansion box of belt 15 and another adjacent hydraulic support protection belt 15 to realize and overlaps, and realizes adjacent
The closing and protection in gap between hydraulic support.

It withdraws, secondary protecting side plate 2 can rotate freely, and can guarantee the flexibility of wall supporting intensity and recycling.It when in use, can be free
The overhang of three-level case telescopic jack 11 is adjusted, the supporting height variation of hydraulic support is required to meet different height.
Side protecting mechanism makes secondary protecting side plate 2 be in appropriate during withdrawal, by adjusting the overhang of secondary protecting side plate jack 8
Upright position, adjust the overhang of three-level expansion box 3 to form reliably gangue stopping device, can effectively avoid flying cash to people
The security threat of row of channels, coal excavation apparatus.
As Fig. 1 and Fig. 2 jointly shown in, after coal mining machine roller coal cutting, hydraulic support is very heavy to three-level expansion box in time
11 times liquid feed flows are pushed up, three-level expansion box 3 is withdrawn.After three-level expansion box 3 is withdrawn in place, start to extensible canopy jack (in figure not
Show) feed flow, stretch out extensible canopy 4, and stretch level-one face guard 1 the 5 inlet fluid injection of level-one face guard jack simultaneously
Out.While above-mentioned movement, the angle between secondary protecting side plate 2 and level-one face guard 1 is adjusted.When the stroke of extensible canopy 4 is complete
After portion is stretched out, level-one face guard 1, secondary protecting side plate 2 should contact coal wall.Reply 11 inlet of three-level expansion box jack supplies at this time
Liquid extends downwardly three-level expansion box 3 under the guiding role of secondary protecting side plate 2, and the lower part of three-level expansion box 3 is made to be inserted into bottom
Plate, then each jack feed flow, makes each jack reach setting load.
As Fig. 3 and Fig. 4 jointly shown in, mine when, full protection wall supporting gangue stopping device withdraw, secondary protecting side plate 2 is two
It is reversely rotated under the action of grade face guard jack, becomes working face gangue stopping device, stretched when secondary protecting side plate 2 is as gangue stopping device
Length can adjust under the action of secondary protecting side plate jack 8 out, be suitable for the variation of coal mining height.When full protection wall supporting keeps off cash
When device needs to withdraw, according to the opposite maneuvering sequence of above-mentioned movement.
