Including 2 groups of anchor cables, each c-type cassette tape ring one end is equipped with hook, and the other end is equipped with upper plate and lower plate, the two compartment one on the other
Away from anchor cable outer diameter is more than or equal to, and slot opposing upper and lower is had in upper plate, lower plate, and be furnished with a plate, the plate
It is fixed on c-type cassette tape ring by chain, slot is provided on the plate, lower plate is equipped with a vertical pivot, which is cased with a steel
Muscle ring, the reinforced steel bar ring are made of a reinforcing rod, and reinforcing rod front end curves grab, and reinforcing rod rear end curves grip ring, the anchor cable
Positioned at adapted hydraulic prop side, c-type cassette tape ring is surround correspondingly to be covered on adapted hydraulic prop, each C
Hook on type cassette tape ring is hung on anchor cable, and upper plate and lower plate bypass corresponding adapted hydraulic prop, and anchor cable is clipped in
Centre, the plate are inserted into slot, block anchor cable from outside, the grab is caught in the slot of the plate, by plug lock
Extremely.It is designed in this way, unyielding anti-down bar is replaced using anchor cable, convenient for assembling in underground moving, and only need to be using hook
Clamping, the screw element for not needing to turn are easy to assembly, quick.
As optimization, two anchor cables one on the other, are fixed on adapted hydraulic prop by c-type cassette tape ring respectively,
C-type cassette tape ring middle section on upper anchor cable is additionally provided with slot case, and the slot box opening is upward, is inside inserted with number plate, outside
A U-shaped window is also provided on wall.It is designed in this way, convenient for management.
As optimization, the anchor cable both ends are cased with steel pipe, and multiple radial tapped through holes are provided on steel pipe, each radial direction spiral shell
Line through-hole is respectively equipped with fastening screw, and fastening screw is against on anchor cable, the c-type cassette tape ring on the adapted hydraulic prop of end
It is fixed on the steel pipe.It is designed in this way, can be not easy to topple over the hydraulic prop of end two.
The hydraulic prop installed can be linked to be an entirety by the present invention, and connection fastening is reliable, can be effectively prevent
Hydraulic prop skew skews and leads to injure by a crashing object personnel, damage equipment.Meanwhile the hydraulic prop of end two uses
The steel pipe of 1.6m long is anti-down, and anchor cable is inserted in steel pipe and is compressed with fastening screw, it is anti-down flexible to solve end point anchor cable
The characteristics of deformation.Middle section hydraulic prop only needs to be fixed with hook, snap fit, easy to connect, rapid, can also use
The waste and old anchor cable of mine, at low cost, convenient transportation.When withdrawing end hydraulic prop, single hydraulic prop back need to only be removed so
Steel pipe retraction can be completed afterwards, working efficiency can be effectively improved.
Hydraulic prop flexible articulation of the present invention interlocking tilting prevention device has the advantages that easy to assembly, quick, fits extensively
The hydraulic prop for being combined into various mines matches.
