Net 6.
Such as Fig. 1, retractable support lever 1 is installed between the back timber 71 of hydraulic support 7 and base 72, retractable support lever 1
There are three sections, including fix bar 11 positioned at bottom, the first motion bar 12 for being placed in the fix bar 11 and be placed on the first work
The second motion bar 13 in lever 12, the diameter of the second motion bar 13 is less than the first motion bar 12, the diameter of the first motion bar 12
Less than fix bar 11, therefore the second motion bar 13 may contract in the first motion bar 12, and the first motion bar 12 may contract to fixation
In bar 11, the first motion bar 12 and the second motion bar 13 can be relatively fixed bar and be stretched about 11, so as to realize that flexible folding is protected
The opening of net 6 and folding.Horizontal intermediate bar 3 is connected with the fix bar 11 of adjacent hydraulic support 7, horizontal intermediate bar 3 is socketed on
The top of fix bar 11, and can be rotated around the fix bar 11, horizontal intermediate bar 3 is connected to the bottom of flexible folding protection network 6,
Then stop folding when flexible folding protection network 6 folds into the position.
Such as Fig. 1 and Fig. 2, the top and bottom of retractable support lever 1 are equipped with connector 2, and connector 2 includes the He of magnet 21
Lock ring 22, retractable support lever 1 is adsorbed in back timber 71 by magnet 21 and on base 72, magnet 21 is I-shaped magnet, magnet
21 one end is adsorbed in the top of retractable support lever 1, and the other end of magnet 21 is adsorbed in the back timber 71 or base of hydraulic support 7
72 so that retractable support lever 1 is fixed on back timber 71 and base 72 by magnet 21.Lock ring 22 is enclosed within magnetic including two semi-rings
The middle part of iron 21, and mutually fixed by bolt so that lock ring 22 can be rotated around the axle of magnet 21.Such as Fig. 3, the one of lock ring 22
End is connected with universal joint 4, and universal joint 4 is twin steering universal joint, and lock ring 22 is fixed in one end of universal joint 4, and the other end is solid
Surely it is connected to transverse support bar 5 so that transverse support bar 5 can rotate certain angle relative to retractable support lever 1.
Such as Fig. 1 and Fig. 4, transverse support bar 5 is connected to the retractable support lever 1 of adjacent hydraulic support 7 by universal joint 4
On, it can be moved up and down with retractable support lever 1.Transverse support bar 5 is included positioned at the transverse bar 51 of both sides and positioned at two
Connecting rod 52 between transverse bar 51, the side of transverse bar 51 is connected to the connecting rod 52, and opposite side is connected to universal joint 4,
The internal diameter of connecting rod 52 is less than transverse bar 51, and the two ends of connecting rod 52 are provided with block 53, and the height of block 53 is more than connecting rod 52
Diameter, block 53 enters in the endoporus of transverse bar 51, and the end face of transverse bar 51 is provided with the block of baffle plate 54 in block 53, the company of preventing
Extension bar 52 is deviate from, and is connected with spring 55 on block 53, and spring 55 is located between block 53 and baffle plate 54 so that connecting rod 52 can be
Elongation or compression in the endoporus of transverse bar 51, spring 55 can reduce impulsive force in collision process, play good cushioning effect, when
When hydraulic support 7 is to reach frame, the rotatable certain angle of universal joint 4 prevents that transverse support bar 5 from fractureing, while transverse support bar 5
Can gradually be extended with the reach of hydraulic support 7, the distance between two transverse bars 51 of extension, it is ensured that hydraulic support 7 it is smooth
It is mobile.
Attachment spacers 56 is welded with such as Fig. 1, transverse bar 51, attachment spacers 56 is bolted to flexible folding protection
Net 6, the flexible folding protection network 6 is interfixed by multi-disc and formed, when transverse support bar 5 with retractable support lever 1 together
When moving up and down, flexible folding protection network 6 can be opened and folded up.
Such as Fig. 1 and Fig. 4, hydraulic support 7 is during support, and retractable support lever 1 rises therewith, drives transverse support bar
5 move upwardly together, while flexible folding protection network 6 is gradually increasing, spread apart, keeps off between adjacent hydraulic support 7, prevent
The coal cinder or spoil produced in coal-winning machine cutting course, which splashes to enter, causes device damage or personnel casualty accidentses.Work as hydraulic support
4 when falling frame, and retractable support lever 1 shrinks, and the magnet 21 on its top departs from back timber 71, as retractable support lever 1 declines, simultaneously
Transverse support bar 5 is also moved down, the folding shrinking of flexible folding protection network 6.When hydraulic support 7 moves frame, the hydraulic pressure branch of both sides
Frame 7 is not simultaneously mobile, but first moves the hydraulic support 7 in front, then moves the hydraulic support 7 at rear, when the hydraulic pressure in front
When support 7 is moved forward, universal joint 4 can make forward and backward hydraulic support 7 there is certain angle, prevent the folding of transverse support bar 5
It is disconnected, while transverse bar 51 and the scalable setting of connecting rod 52 so that transverse support bar 5 is with the reach of the hydraulic support 7 in front
Extend a segment distance, it is ensured that two hydraulic supports 7 are connected all the time.
The above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be appreciated by those skilled in the art that technical scheme can be modified or waited
With replacing, without departing from the objective and scope of the technical program, it all should cover in scope of the presently claimed invention.
