Description
Technical field
The present invention relates to a kind of hydraulic hoist technical field, relate in particular to a kind of torch dual control integrated hydraulic hoists.
Background technique
Traditional hydraulic hoist generally comprises hydraulic system and oil hydraulic cylinder, under the control of hydraulic system, piston body inwall in oil hydraulic cylinder is done axially reciprocating, thereby connecting rod and gate that band is automatically connected on piston are done straight line motion, with the purpose that reaches unlatching, closes aperture.
Hydraulic system comprises power plant, regulating and controlling device, auxiliary device etc.Power plant are generally oil hydraulic pump, and it is converted into hydraulic energy to mechanical energy; The regulating and controlling device refers to the control valve group, comprises the valve groups such as throttle valve, selector valve, relief valve, and its effect is that the aspects such as flow to hydraulic oil, direction, pressure play the control regulating action separately, to realize the various performance requirements to hydraulic system; Auxiliary device comprises fuel tank, oil pipe, pipe joint, pressure gauge, oil purifier etc., the purposes of fuel tank is oil storage and heat radiation, and can precipitate well cuts, air in separating oil and moisture etc., oil pipe, pipe joint couple together power plant, control set for adjusting, oil hydraulic cylinder, form a complete oil hydraulic circuit, the hydraulic pressure well cuts can make the moving parts wearing and tearing, increase the life-span of revealing and reducing element, blocking valve group etc. even, affect the use of hydraulic system, it is very necessary arranging that oil purifier filters hydraulic oil.
The control voltage that the Automation Elements such as the solenoid valve in hydraulic system adopt is all DC24V, the power supply that the oil pump motor group adopts is AC380V, need the participation of electric control system, electric control system comprises contactor, the Automation Elements such as thermorelay, auxiliary reclay, 24V switch power, tutorial light, knob, electric control system can realize hand automatically and the operation of prosecutor formula far away, and automaticity is high.The water conservancy and hydropower hydraulic hoist can be safe and reliable operational relation can normal power generation to power station and flood duration can the normal door flood discharge, power station is in the situation that flood duration occurs that all power supplys have a power failure, traditional hydraulic hoist automatically reaches under the remote-control operation mode and all can not realize the oil hydraulic cylinder regular event at hand, thereby can not realize the gate opening flood discharge.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve existing hydraulic hoist in the situation that the problem that the short of electricity oil hydraulic cylinder can't move the invention provides a kind of torch dual control integrated hydraulic hoists and solve the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: a kind of torch dual control integrated hydraulic hoists, comprise hydraulic system and oil hydraulic cylinder, described hydraulic system comprises the control valve group, the first high-pressure ball valve group, mailbox, the oil pump motor group, air-strainer, return oil filter, described control valve group is connected with oil hydraulic cylinder by the first high-pressure ball valve group, described control valve group and oil pump motor group are arranged in fuel tank, described oil pump motor group is connected with the control valve group, described return oil filter is connected with the control valve group, described air-strainer is arranged on mailbox, described hydraulic system also comprises the second high-pressure ball valve group and hand pump, described hand pump is connected with oil hydraulic cylinder by the second high-pressure ball valve group, described hand pump is arranged on fuel tank.
The invention has the beneficial effects as follows, this torch dual control integrated hydraulic hoists can rely on hand pump to control the oil hydraulic cylinder action in the situation of short of electricity, thereby guaranteed the opening and closing of the gate that is connected with oil hydraulic cylinder, strengthened the safety reliability of hydraulic system, and easy and simple to handle, easy to implement.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the hydraulic scheme of torch dual control integrated hydraulic hoists of the present invention.
Fig. 2 is the optimum embodiment's of torch dual control integrated hydraulic hoists of the present invention structural representation.
In figure 1, oil hydraulic cylinder, 2, the control valve group, the 3, first high-pressure ball valve group, 4, fuel tank, 5, the oil pump motor group, 6, air-strainer, 7, return oil filter, the 8, second high-pressure ball valve group, 9, hand pump.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Fig. 1～2, the invention provides a kind of torch dual control integrated hydraulic hoists, comprise hydraulic system and oil hydraulic cylinder 1, hydraulic system comprises control valve group 2, the first high-pressure ball valve group 3, fuel tank 4, oil pump motor group 5, air-strainer 6, return oil filter 7, control valve group 2 is connected with oil hydraulic cylinder 1 by the first high-pressure ball valve group 3, control valve group 2 and oil pump motor group 5 are arranged in fuel tank 4, oil pump motor group 5 is connected with control valve group 2, return oil filter 7 is connected with control valve group 2, air-strainer 6 is arranged on fuel tank 4, hydraulic system also comprises the second high-pressure ball valve group 8 and hand pump 9, hand pump 9 is connected with oil hydraulic cylinder 1 by the second high-pressure ball valve group 8, hand pump 9 is arranged on fuel tank 4.
In the situation that power supply can normal power supply, the staff can be central station of floating dock or on-the-spot the manipulation by the keying of electronic fingertip control driven open/close gate, if power failure or power supply are because emergency situations causes damaging, the staff need arrive on-the-spot, close the first high-pressure ball valve group 3 by manually-operable, thereby torch dual control integrated hydraulic hoists is switched to manual operation state, then operates the gate that hand pump 9 cut out or opened hoist.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
