Dynamic, rotation, assembling are inconvenient, and its retaining mechanism is tightened by the lead screw on fastening handle 5, and assembling speed is slowly, unfavorable
In quick securing unit hydraulic prop.
The content of the invention
The technical problem to be solved in the present invention is the drawbacks described above for how overcoming prior art, there is provided a kind of monomer hydraulic branch
Post flexible articulation interlocking tilting prevention device.
In order to solve the above technical problems, this hydraulic prop flexible articulation interlocking tilting prevention device includes c-type cassette tape ring, also
Including 2 groups of anchor cables, each c-type cassette tape ring one end is provided with hook, and the other end is provided with upper plate and lower plate, the two compartment one on the other
Slot opposing upper and lower is had on more than or equal to anchor cable external diameter, and upper plate, lower plate, and equipped with a plate, the plate
It is fixed on c-type cassette tape ring by chain, slotted eye is also provided with the plate, lower plate is provided with a vertical pivot, and the vertical pivot is cased with one
Reinforced steel bar ring, the reinforced steel bar ring is made up of a reinforcing rod, and reinforcing rod front end curves grab, and reinforcing rod rear end curves holds ring, the anchor
Rope is located at adapted hydraulic prop side, and c-type cassette tape ring surround be enclosed within adapted hydraulic prop correspondingly, each
Hook on c-type cassette tape ring is hung on anchor cable, and its upper plate and lower plate bypass corresponding adapted hydraulic prop, and anchor cable is clipped in
Centre, in the plate insertion slot, anchor cable is blocked from outside, and the grab is snapped in the slotted eye of the plate, by plug lock
Extremely.It is so designed that, unyielding anti-down bar is replaced using anchor cable, be easy in underground moving, assembles, and only need to be using hook
Clamping is easy to assembly, quick without the screw element that needs are turned.
Used 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 stage casing on upper anchor cable is additionally provided with slot case, and the slot case opening upwards are inserted with numbering plate, outside it in it
A U-shaped window is also provided with wall.It is so designed that, is easy to management.
Used as optimization, the anchor cable two ends are cased with being provided with multiple radial direction tapped through holes on steel pipe, and steel pipe, each radial direction spiral shell
Line through hole is respectively equipped with trip bolt, and trip bolt is against on anchor cable, the c-type cassette tape ring on the adapted hydraulic prop of termination
It is fixed on the steel pipe.It is so designed that, can be difficult to topple over the hydraulic prop of termination two.
The hydraulic prop that the present invention will can be installed is linked to be an entirety, and connection fastening is reliable, can effectively prevent
Hydraulic prop is crooked or skews and causes to injure by a crashing object personnel, damage equipment.Meanwhile, the hydraulic prop of termination two is used
Steel pipe 1.6m long is anti-down, anchor cable is inserted in steel pipe and is compressed with trip bolt, solves end anchor cable anti-down flexible
The characteristics of deformation.Stage casing 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, low cost, convenient transportation.When withdrawing termination hydraulic prop, single hydraulic prop back need to only be removed so
Steel pipe retraction can be completed afterwards, operating efficiency can be effectively improved.
Hydraulic prop flexible articulation of the present invention interlocking tilting prevention device has easy to assembly, efficiently advantage, suitable extensively
The hydraulic prop for being combined into various mines is supported the use.
