Description
Technical field
The present invention relates to circulation shift-forward type advance timbering technical fields, advanced for recycling shift-forward type more particularly, to one kind
The anti-down mechanism of bracket.
Background technique
Hydraulic support is a kind of common support apparatus in fully mechanized mining mine.Existing automatic moving type advance support of taking a step is with work
The stepping each time in face is required to Forward once, and in moving process, each bracket is required to be gone up and down at least once, with
Just to the support repeatedly of the top plate formation sequence in supporting region, cause the integrality of top plate by very havoc.For broken top
Plate, this support pattern easily cause the secondary loosening of country rock, destroy the globality in tunnel；Meanwhile when advance support section away from
From it is too long when, the fltting speed for automatic moving type forepoling hydraulic support of taking a step is excessively slow, does not adapt to the need that working face quickly propels
It wants.The circulation shift-forward type forepoling hydraulic support occurred in the recent period has many advantages, such as that structure is simple, light-weight, shifting frame is convenient, has
Effect solves automatic moving type forepoling hydraulic support of taking a step and supports back that back integrality is caused to be destroyed repeatedly
The problems such as, it has obtained gradually promoting and applying.But existing circulation shift-forward type forepoling hydraulic support is not configured effectively
Anti-down mechanism, support stability is poor, easily occurs askew frame, the problems such as falling frame in use process, and safety is poor.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of for recycling the anti-down mechanism of shift-forward type advance timbering, skill
Art scheme is as follows:
The anti-down mechanism of the present invention for being used to recycle shift-forward type advance timbering, including pedestal, the horizonal base plate of the pedestal
Two sides are respectively arranged with the support plate being hinged therewith, and support jack, institute are provided between the support plate and the vertical plate of pedestal
The both ends for stating support jack are hinged with support plate and base vertical plate respectively, when the piston rod of support jack stretches out, support
Swinging is 5 ° of horizontal plane or less under the maximum of plate, when the piston rod of support jack retracts, the maximum of support plate and horizontal plane
Angle is 90 °, longitudinal tread plate of at least one with ground touching is provided in each support plate, and the pedestal is vertical
Limited block is provided on the outside of plate.
Provided by the present invention for recycling the anti-down mechanism of shift-forward type advance timbering, structure is simple, easy to use, can be compared with
Poor circulation shift-forward type forepoling hydraulic support stability, easy askew frame or the problems such as falling frame are solved well, can be effectively improved and be set
Standby safety ensures the personal safety of operator.
Detailed description of the invention
Fig. 1 is schematic perspective view of the invention.
Fig. 2 is schematic view of the front view of the invention.
Specific embodiment
As shown in Figure 1, 2, of the present invention for recycling the anti-down mechanism of shift-forward type advance timbering, including pedestal 1, bottom
The horizonal base plate two sides of seat 1 are respectively arranged with the support plate 2 being hinged therewith, and branch is provided between support plate 2 and the vertical plate of pedestal 1
Support jack 3.Specifically, the connecting plate welded in support plate 2 is hinged by the otic placode welded on pin shaft and 1 horizonal base plate of pedestal
It is connected, the otic placode for connecting support jack 3 is also respectively welded on 1 vertical plate of support plate 2 and pedestal, support jack 3
Cylinder bottom and piston rod pass through pin shaft and are hinged and connected with above-mentioned otic placode.Support plate 2 by the stretching of 3 piston rod of support jack or
It withdraws and is swung around it with 1 articulated shaft of pedestal, when the piston rod of support jack 3 stretches out, swinging is under the maximum of support plate 2
5 ° below horizontal plane, guarantees that support plate 2 can be contacted tightly with roadway floor, improve the lateral stability of bracket；Further
Ground is also welded with longitudinal tread plate 4 of at least one with ground touching on the lower surface of support plate 2, to improve anti-down effect
Fruit.When the piston rod of support jack 3 retracts, it can be to follow that the maximum angle in support plate 2 after pendulum with horizontal plane, which is 90 °,
Ring shift-forward type advance timbering, which smoothly moves forward, provides sufficient transport space.It is provided with limited block 5 on the outside of the vertical plate of pedestal 1, is used for
It limits support plate 2 and is greater than 90 ° because of active force or by upper swinging caused by Dynamical Cause, prevent support jack 3 from damaging.
In addition, the piston rod when support jack 3 stretches out, and when making 2 bottom of support plate and being contacted with roadway floor, Ke Yiti
Entire bracket is risen, to realize that bracket lifts bottom function.
