On bracket fix, and can be moved up and down along bracket, the top of axis is connected with hydraulic cylinder, and Driven by Hydraulic Cylinder axis moves up and down；?
It folds the small rack being mounted on column below arm and is equipped with limit switch.
The folding arm includes inner arm and outer arm, connects and can relatively rotate by pin shaft between the inner arm and outer arm；
The outer arm is equipped with handle, and pulling handle can fold and be rotated by outer arm, support stake is driven to be pivoted and fold arm itself
Inner arm and outer arm, which mutually rotate, realizes certain plane domain support.
The hydraulic cylinder is controlled by control valve group, and the hydraulic protecting oil circuit of the control valve group and comprehensive Lubricating pump station connects
It connects, may be selected to disconnect by two-position three way magnetic valve or access, hydraulic oil is unidirectional through three position four-way electromagnetic valve, double hydraulic control when access
Valve, one-way throttle valve enter hydraulic cylinder, and pass through its movement of three position four-way electromagnetic valve commutation control.
The utility model has the advantages that the present invention controls hydraulic cylinder by solenoid directional control valve, drives the support stake of safety cock to move up and down, make
It can be placed in the lower die of different height；By pulling folding rotating arm, the support stake of safety cock is driven to rotate, swing,
It can be placed in the supporting surface of lower die, structure type is simple, and it is easy for installation, safety cock is placed instead of manual handling
In lower die, working efficiency is improved, is used manpower and material resources sparingly.

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Fig. 1 show structural schematic diagram of the invention.
The present invention provides a kind of folding arm hydraulic lifting safety cocks, including support stake 1, folding arm 3, axis 7, limit switch
8, bracket 9 and hydraulic cylinder 5.
The support stake 1, which is placed in, folds 3 one end of arm, places spring 2 therebetween, and damage when support is avoided to fold arm.
The other end for folding arm 3 is mounted on axis 7, can be rotated, can also be moved up and down with axis 7 around axis 7.
The bracket 9 that the axis 7 is fixed on column side wall 10 by two is fixed, and can move up and down along bracket 9, axis 7
Top be connected with hydraulic cylinder 5,5 drive shaft 7 of hydraulic cylinder move up and down.
Small rack is equipped on folding the column below arm 3, which is equipped with limit switch 8, for detecting safety
Bolt supports 1 use state of stake.
The folding arm 3 includes inner arm 31 and outer arm 32, is connected, simultaneously between the inner arm 31 and outer arm 32 by pin shaft 33
It can relatively rotate；The outer arm 32 is equipped with handle 4；Pull handle 4 and outer arm 32 can be folded and be rotated, drive support stake 1 around
The rotation of axis 7 and the mutually rotation of folding arm 3 itself inner arm 31 and outer arm 32 realize certain plane domain support (such as Fig. 2 a, 2b, 2c institute
Show).
Fig. 3 show hydraulic schematic diagram of the invention.
Fig. 3 a show the partial enlarged view of Fig. 3 of the present invention.
The hydraulic cylinder 5 is controlled by control valve group, the hydraulic protecting oil circuit of the control valve group and comprehensive Lubricating pump station
Connection, may be selected to disconnect or access by two-position three way magnetic valve 11, and hydraulic oil is through three position four-way electromagnetic valve 12, biliquid when access
Check valve 13 (hydraulic lock), one-way throttle valve 14 are controlled into hydraulic cylinder 5, and it is dynamic by 12 commutation control of three position four-way electromagnetic valve
Make.
Application method of the invention:
In use, pulling the handle 4 for folding arm 3, make that stake 1 is supported to swing in a certain range, while hydraulic cylinder 5 drives branch
It supports stake 1 to move up and down, achieves that support stake 1 can be arbitrarily placed on the lower die supporting surface of different height, different location in this way.
The present invention controls hydraulic cylinder by solenoid directional control valve, drives the support stake of safety cock to move up and down, can put
It sets in the lower die of different height；By pulling folding rotating arm, the support stake of safety cock is driven to rotate, swing, it can
It being placed in the supporting surface of lower die, structure type is simple, and it is easy for installation, safety cock is placed in lower die instead of manual handling,
Working efficiency is improved, is used manpower and material resources sparingly.
The embodiment above of the present invention, is merely illustrative, be not it is only, it is all within the scope of the present invention or it is equivalent this
Change in the range of invention is surrounded by the present invention.
