Shown in Figure 2 is the hydraulic system part
Because lifting lane device of the present utility model requires stable working, reliable.As power delivery mode, this utility model has adopted hydraulic system to finish, and pressure can be converted to mechanical energy.Press fluid endless form difference in the hydraulic system, can be divided into open system and closed system.Because characteristics such as former structure is simple, working stability, little, the oily temperature rapid heat dissipation of energy loss so this utility model has adopted open type hydraulic system, mainly comprise: place fuel tank 5, multiposition control combination valve 6 and oil pump 7 (as Figure 1-3) in the frame 10.In the present embodiment be with the single entry dosing pump as oil pump 7, also comprise overflow valve 18, bidirectional hydraulic lock 24 tilts and level two oil cylinder 22,23, filter screen assembly 17, Pressure gauge 19, one-way throttle valve 20 and pressure switches 21.
Said remote control electric technology mainly comprises: main circuit A, auxiliary circuit B and remote control circuit C.
Fig. 3-the 1st, main circuit A of the present utility model and auxiliary circuit B:
(1) main circuit A partly comprises: motor M, fusing device, relay, catalyst, on and off switch, for three phase mains inlet wire first the leakage switch protection is arranged, second has air switch to make the break, overload open-phase protection, and fuse is made open circuit protection.
(2) auxiliary circuit B part mainly comprises: control circuit, holding circuit, circuit breaker, catalyst, coil and auxiliary contact, transformator and control knob.In the present embodiment, be to adopt transformator to be depressurized to 27V, obtain safe DC voltage 24V by rectification again, make D.C. contactor, relay, solenoid valve.
The two rolling 220V/27V of transformator, elementary 220V, secondary is 27V, power 150W.
D.C. contactor adopts sky and water D09/24V, specified consumption 10A.
The JTX relay helps the contact as pair, all adopts 5A.
Control circuit has air switch, screw base fuse to protect.
Fig. 3-the 2nd, remote control circuit C: mainly comprise: by the radiating portion C of chip component, knob, remote control transmitter (abbreviating remote controller as), receptor and antenna formation
1, receiving unit C
2With auxiliary electrical C
3In the present embodiment, adopt the F21 product, tranmitting frequency is 300～400Mc, and effectively receiving range is 0～50m.For remote control circuit C mainly is to receive and emission two parts C
1, C
2
The control system of said remote control circuit comprises:
(1) automatic part: contain startup, stop, resetting, rise automatically (by transmitting on the remote controller buttons to receptor, be transferred on the control circuit by receptor, the electromagnetic valve starting motor finishes rising, move to level altitude and distance stops automatically again; Automatically it is then opposite to descend, and finishes translation, descends, automatically resets);
(2) crawl part: contain startup, stop, resetting, as will finishing rising → translation (stretching), translation (contracting) → some actions that descends needs press a key that the pass is fixed of 4 keys of remote controller.After receptor receives signal, be transferred to control circuit, the electromagnetic valve starting motor is finished single movement until the finger release button.
(3) on the remote controller independent magnetic switch is set also in addition, pulls out after finishing, the The whole control part all stops, and can't start.
As this utility model of above-mentioned structure, in use, at first carry out foundation ditch in position in advance, device is located in the foundation ditch, and the operation platform of original state device flushes with ground.When needs use this utility model device, people on the tricycle for the disabled and trammer enter the operation platform of this device simultaneously, the end user uses a teleswitch operation platform risen to needs height, and operation and control platform automatic horizontal direction motion makes operation platform arrive at the upper end platform of stairway step.Tricycle for the disabled is released by the people of back or oneself is shaken out platform, enters step upper end platform, by remote controller operation platform is dropped in the foundation ditch again, makes operation platform concordant with road surface, step lower end and return to original original state.Concrete operating process is:
Mainly solve two different displacement actions.One is the vertical displacement of operation platform, and another is the horizontal displacement of operation platform.
The action of vertical displacement is carried out: at first be by the user remote controller, control starts remote control system, after the receptor received signal, is transferred to control circuit, and by the electromagnetic valve starting motor, hydraulic system oil pump is started working, and provides dynamicliquid pressure oil to enter in the oil.Piston is done straight line displacement forward under the effect of hydraulic oil.The piston rod that connects piston tip is made fulcrum by connecting pin, acts on the toggle middle-end.When piston was made slide displacement, the toggle middle-end was made center of circle supporting-point with frame place connecting plate, made circular arc and promoted displacement.Under the supporting role of operation platform infra overhung crank linkage, do the displacement forward of displacement vertically upward and level.When the oil cylinder inner carrier is made a travel displacement to the top, toggle is moved to terminal point as circular arc, operation platform rises to specified displacement height, after having finished operation platform and refering in particular to action, do the instruction that descends by control system, the oil circuit in the hydraulic system acts on the oil cylinder inner carrier, do the rightabout displacement, toggle is done circular arc displacement in the other direction under the supporting of piston rod, make operation platform return to initial condition.
The action of horizontal displacement is carried out: after vertical displacement arrives specified altitude assignment, automatically start by the control system stop, the HYDRAULIC CONTROL SYSTEM valve of horizontal displacement mechanism moves forward the piston in the cross cylinder under the effect of hydraulic oil, make the piston rod of piston nose act on supporting-point displacement forward simultaneously on the operation platform, after operation platform arrives assigned address, stop automatically.After the answer instruction was started by remote controller, the cross cylinder inner carrier made operation platform be recovered to initial condition in the other direction under hydraulic oil acts in the hydraulic system.
What should point out is: because the action of vertical and horizontal both direction is done in the load that toggle on frame and the storing frame and operation platform will carry constant weight.Therefore, determine the technical data of device various piece, can guarantee that just whole device reaches desired target according to parameters such as desired load, speed and height.
By said structure and running thereof, illustrate that fully this utility model is rational in infrastructure, easy and simple to handle, operation platform can be crossed over various step reposefully safely and reliably.
