Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 , image 3 As shown, the transition plate used for the pneumatic hydraulic jack in this embodiment includes a transition plate body 51 , and the transition plate body 51 is provided with an oil supply passage 52 communicating with the jack oil tank (not shown) and the jacking cylinder 1 . The transition plate body 51 is also provided with an exhaust hole 571 which communicates with the oil supply oil passage 52 and leads to the outside of the transition plate body 51 , and an exhaust valve is arranged in the exhaust hole 571 . When the jack is working, the exhaust valve is in a closed state; during maintenance or when exhaust is required, the residual gas in the oil supply oil circuit 52 can be discharged by opening the exhaust valve, so as to ensure that the pneumatic booster 6 can pump oil normally when the ...

Abstract

The invention discloses a pneumatic hydraulic jack and a transiting plate for the pneumatic hydraulic jack. The transiting plate comprises a transiting plate body, wherein an oil supply channel for communicating a jack oil tank and a jack oil cylinder is arranged on the transiting plate body; an exhaust hole which is communicated with the oil supply channel and leads to the outer side of the transiting plate body is arranged on the transiting plate body; a vent valve is arranged in the exhaust hole; the jack comprises the jack oil cylinder, an oil tank, a pneumatic booster and the transiting plate; and the oil tank is connected with the jack oil cylinder through the oil supply channel on the transiting plate and is used for pumping the hydraulic oil into the jack oil cylinder through the pneumatic booster connected with the oil supply channel. The transiting plate for the pneumatic hydraulic jack has the advantages of simple structure, low cost, reliable work, capability of reducing vibration and noise, capability of increasing precision of an executing mechanism, capability of prolonging service life of the hydraulic oil and the like.

Description

technical field [0001] The invention mainly relates to the field of hydraulic jacks, in particular to a transition plate for a pneumatic hydraulic jack and a pneumatic hydraulic jack. Background technique [0002] Pneumatic hydraulic jacks generally include a jacking cylinder, a fuel tank, a transition plate and a pneumatic booster. The fuel tank is connected to the jacking cylinder through the oil supply circuit on the transition plate, and the hydraulic oil is pumped into Lift the cylinder. [0003] Since the hydraulic oil is in contact with the atmosphere during production, storage and transportation, a certain amount of air is dissolved in the oil, and there are many throttle ports on the oil supply circuit of the transition plate. When the hydraulic oil flows through the throttle ports at high speed, When the absolute pressure drops to the air separation pressure of the oil, the air in the hydraulic oil is folded out, so that the fine air bubbles originally dissolved i...
