The shortcoming of this car lug is as follows: at first, the locking poor-performing of pin, when pin remain on for a long time vertically and level between the centre position time because oil leaks, pin is reduced gradually; Secondly, if occur having a power failure when pin is horizontal, then pin can't be got back to vertical release position.
Summary of the invention
One object of the present invention will overcome above-mentioned shortcoming exactly, provides a kind of locking good and can pin be recovered to the hydraulically driven car stop of vertical position when having a power failure.
Hydraulically driven car stop of the present invention comprises that a hydraulic system, a pin assembly and are used to drive first oil cylinder of pin, the piston rod of this first oil cylinder is connected with a connecting rod gudgeon, the other end of this connecting rod and a buffer are pivotally connected, motion with the buffering pin, the mid point of connecting rod is fixedlyed connected with the power transmission shaft of pin assembly, become rotatablely moving of pin with reciprocating motion, thereby pin is moved between a horizontal level and a vertical position first oil cylinder; Described buffer comprises one second oil cylinder and a spring; Described car lug also comprises one near switch, detecting the position of connecting rod, thereby controls the reciprocating motion of piston in first oil cylinder.
Described hydraulic system comprises that a fuel tank, a motor and are by this motor-driven oil pump, the oil-out of oil pump is communicated with two branch roads, a branch road directly connects with the pressure port of a three position four-way electromagnetic valve, another branch road leads to fuel tank through an overflow valve, the oil return opening of three position four-way electromagnetic valve also leads to fuel tank, and two working holes of three position four-way electromagnetic valve respectively are connected in series a hydraulic control one-way valve and an one-way throttle valve leads to one of two oil cylinders; With also tell another branch road in the oil circuit that first oil cylinder communicates, serial connection one two-position four-way solenoid valve on this branch road, and be connected in series the oil circuit parallel connection that forms by described one-way throttle valve and described hydraulic control one-way valve.
Those skilled in the art are not difficult to find out, have adopted the double hydraulic control one way valve owing in the hydraulically driven car stop of the present invention, so the locking performance of system's oil cylinder is improved.Owing to adopted two-position four-way solenoid valve, car lug of the present invention has increased the bypass functionality oil circuit, and therefore, under the situation that occurs having a power failure when pin is horizontal, this car lug can utilize a standby storage battery that pin is holded up.
