Abstract
The utility model discloses a pneumatic hydraulic jack comprising a base which is provided with a main lifting oil cylinder, and a lifting rod is arranged in the main lifting oil cylinder. The pneumatic hydraulic jack also comprises a power oil cylinder which is arranged on the base and communicated with the bottom of the main lifting oil cylinder; a piston propeller is arranged in the power oil cylinder; and the top of the power oil cylinder is connected with a pneumatic oil pump. The original manual lever propelling is changed into the pneumatic manner, therefore the labor intensity is greatly reduced, and the efficiency is improved; the flow rate of the high-pressure gas can be controlled, therefore the lifting speed of the jack can be controlled; and the pneumatic oil pump is separated from a jack main body, therefore the operator can operate far away from the heavy object, and the safety is good.
Description
Technical field
The utility model relates to a kind of jack, especially a kind of jack that increases oil pressure with pressurized air as power.
Background technology
The jack of existing market is of a great variety, and it is several roughly to be divided into mechanical jack and hydraulic jack etc., and principle is had nothing in common with each other.On principle, hydraulic jack based on the most basic principle be exactly pascal's principle, in other words, liquid pressure everywhere is consistent, like this, in the system of balance, applied pressure is smaller above the smaller piston, and applied pressure is also bigger on the big piston, can keep the static of liquid like this.So by the transmission of liquid, can obtain the different pressure on the different ends, so just can reach the purpose of a conversion.We common to hydraulic jack be exactly to have utilized this principle to reach the transmission of power.But traditional hydraulic jack need obtain power by parts manual operations such as levers, wastes time and energy, and labour intensity is big, inefficiency.
Summary of the invention
Problem to be solved in the utility model is exactly the shortcoming at prior art, and a kind of Pneumatic hydraulic jack is provided, and adopts pneumatic mode as power, effectively utilizes hydraulic principle, reaches time saving and energy saving, efficient height, safe and reliable, easy to use effect.
For achieving the above object, the utility model adopts following technical scheme: a kind of Pneumatic hydraulic jack, comprise base, the main oil cylinder of lifting is installed on the base, the main act in the oil cylinder is provided with lifting pin, it is characterized in that: comprise also being installed on the base and the actuator cylinder that communicates with main act oil cylinder bottom that be provided with the piston propelling unit in the actuator cylinder, the actuator cylinder top connects Pneumatic oil pump.
Further, described Pneumatic oil pump comprises shoe cream room, the oil outlet that the shoe cream room two ends are provided for connecting the admission port of high-pressure pump respectively and connect actuator cylinder.
Further, Pneumatic oil pump is provided with carries hand, is convenient to Pneumatic oil pump and guides and supports.
Further, the oil outlet of Pneumatic oil pump is connected with the actuator cylinder top by oil pipe, and the circulation of hydraulic oil in the air valve switch control oil pipe is installed on the oil pipe.
Further, push pedal is installed in the lifting pin upper end, and the push pedal both sides are connected with base by drag spring is installed, and when jack unloaded power, lifting pin can retract original position with it by drag spring.
Advantage of the present utility model: adopt original hand lever to advance and change pneumatic mode into, labour intensity reduces greatly, and efficient improves; The flow of high pressure gas can be controlled, and therefore can control the jacking speed of jack; Pneumatic oil pump and jack main body separate design, the operator can carry out operation away from weight, and safety is good.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of Pneumatic hydraulic jack, comprise base 2, the main oil cylinder 1 of lifting is installed on the base 2, the main act in the oil cylinder 1 is provided with lifting pin 10, comprise also being installed on the base 2 and the actuator cylinder 3 that communicates with main act oil cylinder 1 bottom that be provided with piston propelling unit 30 in the actuator cylinder 3, actuator cylinder 3 tops connect Pneumatic oil pump.Pneumatic oil pump comprises shoe cream room 4, the oil outlet 42 that shoe cream room 4 two ends are provided for connecting the admission port 41 of high-pressure pump respectively and connect actuator cylinder 3; Pneumatic oil pump is provided with carries hand 43, is convenient to Pneumatic oil pump and guides and supports.The oil outlet 42 of Pneumatic oil pump is connected with actuator cylinder 3 tops by oil pipe 5, and the circulation of hydraulic oil in the air valve switch 50 control oil pipes 5 is installed on the oil pipe 5.Push pedal 11 is installed in lifting pin 10 upper ends, and push pedal 11 both sides are connected with base 2 by drag spring 12 is installed, and when jack unloaded power, lifting pin 10 can retract original position with it by drag spring 12.
Principle of work: when using jack, the admission port 41 of Pneumatic oil pump connects high-pressure pump, open 5 conductings of air valve switch 50 oil pipes, by air pump the hydraulic oil in the air storing cavity is sent into actuator cylinder 3, promote piston propelling unit 30, piston propelling unit 30 promotes the main hydraulic oil of lifting in the oil cylinder 1, and lifting pin 10 is risen; When jack unloads power, air valve switch 50 is got to the emptying position, hydraulic oil flows back to shoe cream room 4, and drag spring 12 pulling push pedals 11 simultaneously retract original position with lifting pin 10.
