Described hydraulic stem base is respectively hinged at the bottom immediately below corresponding push rod, hydraulic stem on the outside of hydraulic pressure inverted arch trestle
The hydraulic pressure throw of lever be not less than 80cm.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is novel, simple in construction, economic and practical, and easy construction.
2nd, the utility model can both improve that workmen's safety coefficient and can does not influence ultra-wide equipment, material passes through hydraulic pressure
Inverted arch trestle, solve and fail to take into full account that workmen is pacified by inverted arch operation area at present existing for fixed guard rail
Full protection and how can not solve more than the equipment of hydraulic pressure inverted arch trestle width, material by there is asking for fixed guard rail
Topic, turn avoid and install, dismantle repeatedly existing for fixed guard rail, both reached raising safety coefficient purpose and turn avoid
The inconvenience that fixed guard rail is brought.

Guard rail rod 13.
Embodiment
The utility model is described in further detail below in conjunction with brief description of the drawings and embodiment.
Referring to Fig. 1 to Fig. 2, a kind of movable guard rail of hydraulic pressure inverted arch trestle, this guard rail is generally along inverted arch operation
The elongated arrangement of scope；It includes guard rail 13, the hydraulic pressure that the both sides of hydraulic pressure inverted arch trestle 6 are set along the length of hydraulic pressure inverted arch trestle 6
Two hydraulic stems 4 that the outside both sides of inverted arch trestle 6 are set respectively, described hydraulic stem 4 and the phase of hydraulic pressure inverted arch trestle hydraulic system 5
Connection.By being movably hinged I 7 between 10cm below the described bottom of guard rail 13 and the outer top surface of hydraulic pressure inverted arch trestle 6
It is connected, the described base of hydraulic stem 4 is connected with the outer lower end of hydraulic pressure inverted arch trestle 6 by being movably hinged II 10；By hydraulic pressure
