Use the requirement of lead at last, each switch is connected with motor, just do not state here tired according to Fig. 5; Manual button except that far-end button 30 is all focused on switch board 35 places, and far-end button 30 is installed in the monitoring room that can monitor whole public place safety.

For the operation principle of this equipment can be described, we suppose that its original state is such: upper strata counter 4 is stacked on lower floor's counter 5, coaster 3 is blocked by the limited slip plate 6 of track low side, rise switch 7, upper strata counter decline press button 33, traction press button 34 and lower floor's counter decline press button 31 all are in open circuit, two contacts of forward and reverse selector switch 32 respectively and C, D joins, and (the C point links to each other with the positive pole of power supply, the D point links to each other with the negative pole of power supply), upper strata counter position-sensing switch 22 joins with contact A, high-end contact-making switch 8 joins lower floor's counter position-sensing switch 23 closures with contact F.

When pressing when rising switch 7 or pressing far-end switch 30, coaster hoist engine 12 is switched on (other motor is not switched on), coaster hoist engine 12 is started working, upper strata counter 4 is sling, when upper strata counter 4 rose to assigned address, upper strata counter position-sensing switch 22 was touched and is made the contact of this switch skip to B by A; At this moment coaster hoist engine 12 is switched on by open circuit, hauling machine 21, hoist engine 20 still is in open circuit, hauling machine 21 is started working and is drawn to high-end from the low side of track 2 coaster 3, when an end of coaster 3 when high-end contact-making switch 8 above the track 2 high-end limited slip plates 6 contacts, the contact of high-end contact-making switch 8 skips to G from F; Hauling machine 21 is switched on by open circuit, hoist engine 20 at this moment, coaster hoist engine 12 still is in open circuit, hoist engine 20 is started working, lower floor's counter 5 is sling, when lower floor's counter 5 was sling to assigned address, lower floor's counter position-sensing switch 23 was touched, and lower floor's counter position-sensing switch 23 becomes open circuit from path, hoist engine 20 quits work, and at this moment two-layer counter is all sling up and down.At this moment be reset to opening state rising switch 7 or far-end switch 30, the work that whole counter is sling is just accused and is finished.

When needs are fallen counter, at first direct-reverse switch 32 is moved to contact (this moment D point link to each other, the E point links to each other with the negative pole of power supply) with D, E with the positive pole of power supply, at this moment the end that each motor linked to each other with power cathode originally links to each other with positive source, when communicating, this motor can be done reverse rotation when the other end (end that originally links to each other with positive source) of power cathode and arbitrary motor; At this moment press lower floor's counter decline button 31 successively, hoist engine 20 will reverse (counter-rotating refers to as follows with respect to turning to of ascent stage) discharge steel wire rope 25, under the self gravitation effect of lower floor's counter 5, make lower floor's counter 5 assigned address that is put into ground slowly, discharge this button, in the process that descends, lower floor's counter position-sensing switch 23 is released, and this switch becomes open circuit by path; Press hauling machine button 34 then, hauling machine 21 will reverse and discharge steel wire rope 25, under the self gravitation effect of coaster 3 and upper strata counter 4, coaster 3 with upper strata counter 4 slowly from the high-end low side that slides to of track 2, blocked by limited slip plate 6 at last, at this moment discharge this button, in the sliding process of coaster 3, high-end contact-making switch is released, and this switch is connected by connecting to transfer to the F point with the G point; Press upper strata counter decline button 33 at last, coaster hoist engine 12 reverses, discharge steel wire rope 25, under the self gravitation effect of upper strata counter 4, slowly drop to above lower floor's counter 5, the relative position of adjusting two counters makes lower floor's counter 5 these top group latches 16 can insert the slot 17 of the correspondence above the upper strata counter 4, discharges this button, in the decline process of upper strata counter 4, upper strata counter position-sensing switch 22 is released, and this switch is connected by connecting to transfer to the A point with the B point; Again positive direction switch 32 turn back to positive source contact with C, negative pole contacts with D, and rise switch 7 and far-end switch 30 returned to off state, at this moment whole system has been got back to the original state that we set.

Far-end switch 30 is to be on the monitor staff's workbench that can monitor the public place, is to be the switch of monitor staff's special use specially.When emergency case is arranged, the monitor staff can press this far-end switch 30 at far-end and start this system, counter is risen immediately and do not need to notify the staff at counter place, certainly in time notify the staff at counter place simultaneously by public address equipment, counter go up to the air at once take care so just better, but the monitor staff haves no right to control the decline of counter, has only on-the-spot staff can control the decline of counter.
