Description of drawings
Fig. 1 is the elevator partial schematic sectional view.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
With reference to figure 1, a kind of elevator that is used for the convenient lifting of material of the low gradient comprises casing 5, the jacking system 21 that is provided with a hydraulic actuating cylinder 9 and chain-wheel mechanism in the bottom of casing 5 and is driven by hydraulic actuating cylinder 9, chain-wheel mechanism.Chain-wheel mechanism comprises sprocket wheel 8 and chain 7, and 8 on sprocket wheel is located on the axis of the piston of hydraulic actuating cylinder 9 and sprocket wheel 8 can be around self center rotation.Chain 7 is walked around sprocket wheel 8, and its first end 22 is connected with lifting support 11 in the jacking system 21, and second end 23 is connected with casing 5.When the axis of the piston lifting of hydraulic actuating cylinder 9, just can drive jacking system 21 by sprocket wheel 8 and chain 7 and carry out lifting like this.Jacking system 21 comprises lifting support 11, pulley 10 and lifter plate 12, and pulley 10 is installed on the lifting support 11, along being located at track 6 rollings in the casing 5 and carrying out oscilaltion; Lifter plate 12 is captiveed joint with lifting support 11, the lifting with the lifting of lifting support 11; Goods platform 14 is captiveed joint with lifter plate, and lifter plate 12 just can drive 14 liftings of goods platform in lifting process like this.
Hydraulic actuating cylinder 9 on hydraulic fluid port 17,16, be connected with an oil pipe 15, on oil pipe 15, connect a solenoid directional control valve 19, oil pipe 15 is connected with the oil pump (not shown).
Be provided with master cock on casing top, master cock comprises scram button 1, rising button 2, stop button 3 and decline button 4, and rising button 2 makes things convenient for the M/C material to rise; Rising button 2 belows are stop buttons 3, are used for the manual shut-down operation after material runs to assigned address; The decline button 4 of stop button 3 belows is used for the decline process of M/C material.Relay is housed in the casing, after the control material rose to assigned address stop setting-up time, the lifting table automatic lowering was avoided unexpected decline in the material handling process, also reduce simultaneously the wait time of subsequent operation, improved efficiency when guaranteeing safety again.
In order to prevent that the goods platform from rushing to summit and in time to stop when landing, bottom and top at casing 5 are provided with upper limit inductive switch 20 and lower limit inductive switch 13, upper limit inductive switch 20, lower limit inductive switch 13 are by lifter plate 12 touchings, and scram button 1, rising button 2, stop button 3, decline button 4, upper limit inductive switch 20, lower limit inductive switch 13 and electromagnetic valve 19 constitute control loop.
In the cargo transport process, this elevator adopts the power of hydraulic pressure as up-and-down movement, provides high pressure oil by extraneous oil pump station.High pressure oil is through change-over valve, and unidirectional control cock is sent into hydraulic actuating cylinder by oil inlet 15 rises and decline work the axis of the piston in the hydraulic actuating cylinder.When opening the rising button 2 of elevator (the solenoid directional control valve ascent direction is started working), oil inlet 17 oil-feeds, the axis of the piston rises and promotes 14 risings of goods platform, oil outlet 16 oil returns this moment, this oil is got back to pumping plant through solenoid directional control valve and oil pipe; 16 oil-feeds of (the solenoid directional control valve descent direction is started working) oil outlet promote 14 declines of goods platform when opening elevator decline shift knob 4, this moment, oil inlet 17 was fuel-displaced, formed an opposite flow direction, this oil is also got back to pumping plant through the oil return pipe of change-over valve, rises successively and the decline duty cycle operation.
When starting rising button 2, extraneous oil pump station provides high pressure oil to hydraulic actuating cylinder 9, at this moment, high pressure oil is through solenoid directional control valve 19, unidirectional control cock is sent into hydraulic actuating cylinder makes the axis of the piston in the hydraulic actuating cylinder play the effect of rising, and the axis of the piston of hydraulic actuating cylinder 9 begins to drive sprocket wheel 8 at this moment and slowly rises, because being connected of chain 7 one ends and lifting support 11, so chain 7 also drives lifting support 11 upward movement together simultaneously, thereby drive goods platform 14 motion together.
When rising to setting height, lifter plate 12 makes upper limit inductive switch 20 close solenoid directional control valve near upper limit inductive switch 20, opens relay fall time simultaneously, and rising stops; When stopping to time of setting, solenoid directional control valve (by relay fall time) is opened (solenoid directional control valve descent direction) automatically and is begun to descend, when dropping to setting low, the decline limiting stopper descends and stops near stopping inductive switch (closing the solenoid directional control valve descent direction).Recover the same mode of operation by the button 2 that once rises again.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
