Handling transport on workshop, warehouse, harbour, station, the goods yard of some fiery articles of inflammable, explosive and taboo and other places is frequent
The hydraulic means controlled manually can be used, such as：Hand fork lifter, manual pallet truck, hydraulic elevating platform etc..Due to its own without
Power supply, it is to avoid produce electromagnetic field or spark, ensured the security used.But existing equipment, its design principle is complicated, structure
It is cumbersome, manufacture high processing costs.
【Utility model content】
In view of this, to overcome the deficiencies in the prior art, the utility model provides a kind of based on the hydraulic pressure controlled manually dress
Put, its is easy to use, reliable, structural principle is simple, and manufacturing cost is low.
To achieve the above object, the technical solution of the utility model is as follows：
It is a kind of based on the hydraulic means controlled manually, including hydraulic jack, plunger case and fuel tank, the hydraulic jack with
The first connected pipes are provided between the plunger case, the second connected pipes are provided between the plunger case and the fuel tank, it is described
First connected pipes are provided with the first check valve, and second connected pipes are provided with the second check valve, first check valve
Ensure that the hydraulic oil in hydraulic means can only enter the hydraulic jack from the plunger case, second check valve ensures liquid
Hydraulic oil in pressure device can only enter the plunger case from the fuel tank.
Further, the plunger case upper end is provided with handle, and the post that the handle makes to set in the plunger case is pulled up and down
Plug moves up and down；During rising, vacuum is formed in the plunger case, the hydraulic oil in the fuel tank is drawn into plunger case；Under
During drop, the plunger in the plunger case promotes hydraulic oil discharge, and second check valve limits hydraulic oil and returns to the fuel tank
Interior, now the hydraulic oil in plunger case can only enter in the hydraulic jack, that is, promote the work set in the hydraulic jack
Stopper rod rises, and reaches the purpose of lifting goods.
The hydraulic jack lower end side is provided with fuel outlet valve, and oil return pipe is provided between the fuel outlet valve and the fuel tank, is beaten
Open the piston rod set in the fuel outlet valve, the hydraulic jack to decline, hydraulic oil is flowed into fuel tank from the fuel outlet valve.
Structural principle of the present utility model is：Using the architectural characteristic of check valve, limitation hydraulic oil can only one-way flow, lead to
Cross pulling handle and promote plunger upward and downward, drive hydraulic oil inspiration and discharge, give hydraulic jack fuel feeding, reach control liquid manually
The purpose of pressure device.
The beneficial effects of the utility model are, easy to use, reliable, and structural principle is simple, and manufacturing cost is low, the scope of application
Extensively.
【Brief description of the drawings】
