Abstract
The utility model discloses a kind of lifting machine hydraulic systems, including fuel tank, motor, oil cylinder and oil pump, the fuel tank is equipped with oil pump, the oil pump side is electrically connected motor, the oil pump is connected with oil cylinder by oil pipe, and the oil pipe is equipped with check valve, the oil pipe side and the top connection shunt conduit for being located at check valve, and shunt conduit bottom is connected to fuel tank, the shunt conduit is equipped with throttle valve and is arranged on the solenoid valve of throttle valve bottom.The utility model is by by motor connecting power, it can work normally, operation of oil pump is driven using motor, control hoistable platform moves up and down work, when oil pipe breaks down, Crack-proof valve quick closedown, cut off the oil stream that leaks of oil cylinder, throttle valve and electromagnetic valve work, make hoistable platform slowly decline, and ensure the safety of the person and equipment.
Description
【Technical field】
The utility model is related to hydraulic elevator technical field, more particularly to a kind of lifting machine hydraulic system.
【Background technology】
Hydraulic elevating platform is used for the mechanical equipment that object is driven to make raising and lowering movement, due to its time saving and energy saving convenience
Efficiently characteristic is by people's extensive use, current hydraulic lifting system when hoistable platform is when high aerial oil circuit breaks down,
It will appear workbench dramatic decrease accident out of control, compromise the safety of personnel, equipment and cargo.For this purpose, it is proposed that one
Kind lifting machine hydraulic system.
【Utility model content】
The main purpose of the utility model is that a kind of lifting machine hydraulic system is provided, in use, by the way that motor is connect
Energization source can work normally, and operation of oil pump is driven using motor, and control hoistable platform moves up and down work, when
When oil pipe breaks down, Crack-proof valve quick closedown cuts off the oil stream that leaks of oil cylinder, throttle valve and electromagnetic valve work, puts down lifting
Platform slowly declines, and ensures the safety of the person and equipment, can effectively solve the problems in background technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of lifting machine hydraulic system, including fuel tank, motor, oil cylinder and oil pump, the fuel tank is equipped with oil pump, the oil
It pumps side and is electrically connected motor, the oil pump is connected with oil cylinder by oil pipe, and the oil pipe is equipped with check valve, the oil pipe one
Side and the top connection shunt conduit for being located at check valve, and shunt conduit bottom is connected to fuel tank, the shunt conduit is equipped with section
Stream valve and the solenoid valve for being arranged on throttle valve bottom.
Further, the shunt conduit is equipped with overflow valve, and the overflow valve side is connected with pressure gauge.
Further, the oil cylinder is equipped with Crack-proof valve.
Compared with prior art, the utility model has the advantages that：It, can by by motor connecting power
Enough normal works drive operation of oil pump using motor, and control hoistable platform moves up and down work, when oil pipe breaks down
When, Crack-proof valve quick closedown cuts off the oil stream that leaks of oil cylinder, throttle valve and electromagnetic valve work, hoistable platform is made slowly to decline, and protects
The safety of the barrier person and equipment.

【Specific embodiment】
To be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, below
With reference to specific embodiment, the utility model is expanded on further.
As shown in Figure 1, a kind of lifting machine hydraulic system, including fuel tank 1, motor 2, oil cylinder 6 and oil pump 11, the fuel tank
1 is equipped with oil pump 11, and 11 side of oil pump is electrically connected motor 2, and the oil pump 11 is connected with oil cylinder 6 by oil pipe 7, described
Oil pipe 7 is equipped with check valve 4,7 side of oil pipe and the top connection shunt conduit for being located at check valve 4, and shunt conduit bottom
Fuel tank 1 is connected to, the shunt conduit is equipped with throttle valve 8 and is arranged on the solenoid valve 9 of 8 bottom of throttle valve.
A kind of lifting machine hydraulic system of the utility model, in use, by the way that motor 2 is powered on, it can be just
Often work drives oil pump 11 to work using motor 2, and control hoistable platform moves up and down work, when oil pipe 7 breaks down
When, the oil stream that leaks of oil cylinder is cut off in 5 quick closedown of Crack-proof valve, and throttle valve 8 and solenoid valve 9 work, under making hoistable platform slow
Drop ensures the safety of the person and equipment.
Wherein, the shunt conduit is equipped with overflow valve 10, and 10 side of overflow valve is connected with pressure gauge 3.
Wherein, the oil cylinder 6 is equipped with Crack-proof valve 5.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
