Bar, folding support bar include the first locking level, the second locking level and angular adjustment bar, one end of first locking level and door body
It is hinged, on the basis of one end of the second locking level is fixed on civil engineering dam by third branch free bearing, the other end of the second locking level leads to
It crosses hinge shaft to be hinged with the first locking level, end of the hinge shaft away from the first locking level is equipped with distance, and lock is connected on the second locking level
Stand oil cylinder, locked cylinder are rotated centered on hinge shaft；The angular adjustment bar is fixedly connected with the first locking level, in angular adjustment
Bar sets multiple lock holes, and multiple lock holes are arranged on the running orbit of locked cylinder, and the piston rod of locked cylinder is plugged on
In one of lock hole of angular adjustment bar.
Second locking level and the first locking level of the utility model are using hinge shaft as coercive mechanism, when opening and closing hydraulic cylinder works,
The angle of first locking level and the second locking level changes.When dam is opened to design angle, the lock hole of the second locking level and
For lock hole in straight line, the locked cylinder on the second locking level carries out locking completion by electrical control system.With such
It pushes away, completes multi-angle locking.The utility model, which effectively solves support, can not complete multi-angle support.This Collapsible support device simultaneously
The advantages that simple in structure novel, performance easy to use, safe is good, mitigation hydraulic headstock gear pressure-bearing.
The support of the utility model is locked using folding principle liquid feeding cylinder pressure；Support device the opening with dam when dam is opened
It opens and auto-folder；When dam Close All；Folding support is at linear state；Hydraulic cylinder parallel motion will under linear state
Folding support lever lock is dead；Ensure the safety on dam；Effectively solve support foundation pit siltation.
For reasonable design, simple, the angular adjustment bar is arc-shaped, the both ends of curved angle adjusting rod with the first lock
Fixed pole is fixedly connected.
Preferably, earrings after the cylinder barrel connection for opening and closing hydraulic cylinder, rear earrings are hinged with first free bearing, open and close liquid
Earrings before the piston rod connection of cylinder pressure, preceding earrings are hinged with second free bearing.When hydraulic pressure dam open when hydraulic cylinder Earrings turn
It moves until dam fully opens.
Preferably, second locking level includes two straight-bars, and the angular adjustment bar is arranged between two straight-bars, and two
Jack is respectively equipped on root straight-bar, two jacks are arranged symmetrically, and locked cylinder is connected on the straight-bar at jack, locked cylinder
When piston rod stretches out, one of lock hole of angular adjustment bar is inserted into from the jack of straight-bar.Angular adjustment bar is arranged on two
Between straight-bar, locking is more reliable, improves safety.
