Abstract
The utility model relates to a can promptly close hydraulic hoist machine of door, including hydraulic cylinder and hydraulic system, hydraulic system includes power pack, valve unit unit and promptly closes a control unit, and the one end of valve unit unit is linked together through oil pipe and power pack, and the other end is linked together with the one end of promptly closing a control unit through oil pipe, and the other end that promptly closes a control unit communicates with hydraulic cylinder, promptly closes a control unit and valve unit unit and all communicates with the oil tank, this kind of can promptly close hydraulic hoist machine of door can rely on manual control high pressure ball valve's closure in the condition of outage, makes hydraulic cylinder realize closing an action to satisfied the operating mode of emergency in the engineering, avoided having strengthened hydraulic system's security and reliability, moreover easy and simple to handle, easy to carry out because of closing the calamity that the door caused.
Description
Technical field
The utility model relates to a kind of hydraulic hoist technical field, particularly relates to a kind of hydraulic hoist that promptly can close door.
Background technique
Traditional hydraulic hoist generally comprises hydraulic jack and hydraulic system, hydraulic jack is generally single-acting (or double-action) piston cylinder, structurally, by oil pipe rod chamber is communicated with rodless cavity and can realizes differential, realize closing door under the deadweight of oil cylinder and gate; Simultaneously under the control of hydraulic system, the piston in hydraulic jack does axially reciprocating in cylinder barrel, thus is with the connecting rod that is automatically connected on piston and gate to do straight line motion, to reach the object in unlatchings, closedown aperture; Meanwhile also can add Differential Control in hydraulic system, realize closing an action.
If but hydraulic jack is single-acting plunger type hydraulic jack, it only has a chamber, structurally with in conventional hydraulic all differential action cannot be realized, if when being difficult to realize without the operating mode that will realize promptly closing door when any electric power.
No matter be water power plant or common sluice now, all very high to the requirement of flood control.Water conservancy and hydropower hydraulic hoist can be safe and reliable operational relation to power station can normal power generation, can sluice flood duration just normal closed gate flood control, every aspect all relates to the person and property safety.And our traditional hydraulic system single-action plunger piston cylinder with the use of under, oil hydraulic cylinder can not be realized and promptly close door, thus bring hidden danger to the person and property safety.
Model utility content
The technical problems to be solved in the utility model is: in order to solve single-acting plunger type oil cylinder coordinate conventional hydraulic time, when short of electricity, hydraulic jack cannot the problem of action, and the utility model provides a kind of hydraulic hoist that promptly can close door.
The utility model solves the technological scheme that its technical problem adopts: a kind of hydraulic hoist that promptly can close door, comprise hydraulic jack and hydraulic system, described hydraulic system comprises power unit, controls valve terminal and promptly close door control unit, one end of described control valve terminal is connected with power unit by oil pipe, the other end is connected with the one end promptly closing door control unit by oil pipe, the described the other end promptly closing door control unit is communicated with hydraulic jack, and the described door control unit that promptly closes all is communicated with fuel tank with control valve terminal.
Concrete, the described door control unit that promptly closes comprises Solenoid ball valve and high-pressure ball valve, and described Solenoid ball valve one end is communicated with hydraulic jack, and the other end is communicated with control valve terminal, described high-pressure ball valve one end is communicated with hydraulic jack, and the other end is communicated with the fuel tank of power unit.
When there being normal continuous stabilized power source, hydraulic oil enters through power unit and control valve terminal the Solenoid ball valve promptly closing gate cell from fuel tank, then enters hydraulic jack through Solenoid ball valve, and gate hydraulic hoist is normally opened; Solenoid ball valve obtains electric, and oil circuit is in on-state, and hydraulic oil is back to fuel tank through Solenoid ball valve, and automatic door-closing under the deadweight of the plunger rod of hydraulic hoist and the deadweight of gate, makes gate hydraulic hoist normally close; If power failure or power supply are because emergency situations causes damaging, staff need arrive scene, manually operate high pressure ball valve, the hydraulic hoist that promptly can close door is switched to manual operation state, hydraulic oil in hydraulic jack is back to fuel tank through high-pressure ball valve, and the plunger rod of hydraulic hoist is automatic door-closing under the deadweight of deadweight and gate.
The beneficial effects of the utility model are, the hydraulic hoist that promptly can close door of the present utility model without any electric power situation the closed of Non-follow control high-pressure ball valve can be relied on to make oil hydraulic cylinder action, thus ensure that the gate normally closed be communicated with oil hydraulic cylinder, enhance the safety and reliability of hydraulic system, and easy and simple to handle, easy to implement.

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of hydraulic hoist that promptly can close door as Figure 1-4, comprise hydraulic jack 1 and hydraulic system, described hydraulic system comprises power unit 4, controls valve terminal 3 and promptly close door control unit 2, one end of described control valve terminal 3 is connected with power unit 4 by oil pipe, the other end is connected with the one end promptly closing door control unit 2 by oil pipe, the described the other end promptly closing door control unit 2 is communicated with hydraulic jack 1, and the described door control unit 2 that promptly closes all is communicated with fuel tank with control valve terminal 3.The described door control unit 2 that promptly closes comprises Solenoid ball valve 5 and high-pressure ball valve 6, described Solenoid ball valve 5 one end is communicated with hydraulic jack 1, the other end is communicated with control valve terminal 3, and described high-pressure ball valve 6 one end is communicated with hydraulic jack 1, and the other end is communicated with power unit 4 fuel tank.
When there being normal continuous stabilized power source, hydraulic oil enters through power unit 4 and control valve terminal 3 Solenoid ball valve 5 promptly closing gate cell from fuel tank, then enters hydraulic jack 1 through Solenoid ball valve 5, and gate hydraulic hoist is normally opened; Solenoid ball valve 5 electric, oil circuit is in on-state, and hydraulic oil is back to fuel tank through Solenoid ball valve 5, and automatic door-closing under the deadweight of the plunger rod of hydraulic hoist and the deadweight of gate, makes gate hydraulic hoist normally close; If power failure or power supply are because emergency situations causes damaging, staff need arrive scene, manually operate high pressure ball valve 6, the hydraulic hoist that promptly can close door is switched to manual operation state, hydraulic oil in hydraulic jack 1 is back to fuel tank through high-pressure ball valve 6, and the plunger rod of hydraulic hoist is automatic door-closing under the deadweight of deadweight and gate.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
