Description

The Yi that band stops layer control draws the formula gig

Technical field

The utility model relates to the automatic floor stopper of cage that a kind of steel rope Yi draws the formula gig, is electromechanical integration technology.

Background technology

Existing steel cable elevator cage stops that layer is many is installing travel switch on every layer height position on the derrick, and cage arrives the interlayer collision that will stop or inductive switch and stops.The man-engine uses this method more at present, but this method is infeasible at the building ground gig, because service-building elevator is interim installing, not protection around the derrick, add that environment is abominable, control cable and switch pole are fragile, add the price height, the maintenance personnel require height, have confirmed infeasible in the practice.At present general using method is that control gig winch involves in what (also being the lifting drum rotational angles) of rope capacity and stops layer, more old fashioned, utilize drum shaft to adorn a screw rod, when rotating, reel drives screw rod upper nut sway, impact switch stops layer, new-type useful winch coiling rotates or the motor rotational angle changes into pulse voltage information, and after conversion Calculation, induction stops layer.Its principle is with use electronic speed probe principle is similar at present, the induction reel rotates the number of times how many angles turn to pulse voltage and transfers numeric display again to, stop layer with giving the pulse digit induction of putting the number of plies, the benefit of this method is to concentrate by driver operation the damage of avoiding control circuit badly to cause because of environment.And the building ground also can not resemble automatic work the man-engine, otherwise greatly dangerous.But the height of the rotational angle that it is exactly winch that this method also has individual necessary usage condition and the rising of cage will have fixing ratio, this ratio can not change, once change stop inaccurate, draw on the gig just not all right so this method is used at Yi, because steel rope and traction wheel are by frictional transmission, steel rope can skid in the groove of traction wheel, and influence gear ratio value, and thereby influence stops the accuracy of layer, it is also comparatively complicated to add that pulse digit stops this cover electronics package of layer, being used on the building ground workman, to operate quality low, environment is abominable, and not really suitable, maintenance, maintenance all is difficult to resolve in the building site determines, often rely on manufacturer, influence job schedule.

Be the patent No. 90201351.3 " steel wire rope with magnetic graduations " near the utility model, its method is to embed small magnetic needle every equal length on steel rope, so that the whole piece steel rope is covered with magnetic dot, measure the number of these magnetic dots and the polarity then running length of steel rope and direction as can be known.The shortcoming of this method is:

1. manufacture method complexity will embed when making steel rope, if ordinary steel rope then be difficult to embed fixing, the cost height is difficult to promote.

2. magnet is generally more crisp, is easy to fragmentation and falls down, and steel rope is when pulley is crooked, and magnet is easier to be cataclasm.

3. detection means is accurate, is unfavorable for generally promoting the use of.

The content of invention

The specific embodiment

This paper does further to comment in conjunction with above accompanying drawing (embodiment).

One, general Yi draws gig as shown in Figure 1, electrical motor 1 drives drop-gear box 4 and drives traction wheel 5 rotations, many steel ropes (being four among the figure) are clipped in traction wheel 5 grooves, one of steel rope hangs cage 7 by head sheave 8, the other end hitches counterbalanced weight 15 by head sheave 8, when cage in the extreme higher position, then counterbalanced weight is at lowest order, that are down on this for cage and counterbalanced weight, direction is opposite, at cage is that a little steel rope is made tricing line 9, the other end passes and is fixed on underground sipes pulley 19 and ties up in screw rod 18 end ring of tensioner apparatus C, spring 17 withstands between nut 16 and the spring perch 13, spring perch 13 is contained on the counterbalanced weight 15 by linking up with 14, tricing line keeps degree of tension by spring 17 elastic force, folder advances a plurality of steel ropes and pricks 10 on tricing line 9, pricking head can adjust up and down and fixing along tricing line 9, induction installation B as shown in Figure 2, be contained in frame or sense base 20 internal fixation on the ground a little axle 21 is arranged, shift fork 12 is enclosed within on the little axle 21 and can rotates up and down in the direction of arrows, it behind the shift fork cam, cam is pressed less than switch 11 during shift fork 12 levels, when shift fork 12 is push-jump by the bundle by fork pockets 10, switch is subjected to cam to push and open or close, realization is drawn the formula hoister control to Yi, prick 10 because of the rotation of shift fork 12 dodge pass through shift fork after, because the pulling force of two springs 22 makes shift fork 12 recover level attitude, the level attitude of shift fork is to keep by spring 22.

Concrete using method is: cage 7 is stopped accurate on the floor level of appointment, one of clamping pricks 10 on the tricing line 9 of shift fork 12 positions, during test-run a machine because cage operation inertia, cage can stop than story height some, adjust to prick a position, can accurately be stopped a layer position, each floor installing is corresponding pricks 10, cooperate electronic counter to use, then can handle on the floor that cage accurately is parked in any predetermined stop.

Fig. 1 bundle of the present utility model fork type induction installation B can also use contactless inductive switch 26, prick 10 and the induction installation D that forms of sipes pulley 19 replace, for example will prick 10 has magnetic or clamps magnet and then can use magnetic induction switch, or to prick head be that conductor then can use near switch, or make and prick first speed and live light and use photoelectric switch or infrared switch.Sipes pulley 19 also have keep pricking 10 with inductive switch 26 apart from the unmodified effect, make and prick 10 and in the induction range of inductive switch 26, pass through.But it will be argued that on-site and use, under the low situation of quality of workers, still comparatively simple, reliable, practical with regular tap.

Two, Fig. 3 is with responding to pulley 24, the schematic diagram of the induction rotating-table apparatus E replacement bundle fork type induction installation B that sensing chip 25, inductive switch 26 are formed on Fig. 1 the utility model basis.

As Fig. 3, tricing line 9 and tightening device C are the same as previously mentioned, tricing line 9 has a circle many on induction pulley 24, make the cornerite of its tricing line 9 reach 360 °+180 °=540 °, to increase the friction of 9 pairs of inductions of tricing line pulley 24, the engineering plastics manufacturing of induction pulley 24 has it and is not with magnetic, nonconducting insulator, in order to avoid influence the action of inductive switch 26.Tumble in the sensing chip 25 of multi-disc conductor or magnet material in the side of induction pulley 24, make inductive switch 26 induction end near sensing chip 25, do not touch but in induction range, when tricing line 9 drags 24 rotations of induction pulley, multi-disc sensing chip 25 successively near and leave inductive switch 26 terminations and inductive switch 26 produced connect and open circuit, its number of times is the same with the number of sensing chip, if cage 7 drags one meter distance of tricing line 9 operations, just made induction pulley 24 rotate a circle, and inlayed 100 sensing chips 25 on the induction pulley 24, then inductive switch 26 meeting power on/off (promptly sending pulse) are 100 times, be that each pulse cage has moved 100cm/100 time=1cm, utilize digital electronic unit, calculate the number of times of pulsing, can calculate the distance of cage operation.Deciding ground by last official holiday is 4 meters to 2 building height, 2-3 building height is 3 meters, then cage is that to play the 2nd buildings should be 400 pulses to 0 pulsimeter by ground, to the 3rd buildings should be the 400+300=700 pulse, other are highly so analogized, use electronics presetting pulse number to stop the method for layer, then can accurately be parked in this floor.For example presetting pulse 700 stops, and then cage can be parked in the 3rd buildings, and cage rising number of pulses increases progressively, and cage falling pulse quantity is successively decreased.

The utility model also adopts following measure to improve to stop the accuracy of layer.

3. increase the cornerite of 9 pairs of inductions of tricing line pulley 24,, make tricing line 9 and induction wheel 24 synchronous to increase friction.

2. reducing the weight of induction pulley 24, to reduce its inertia, mainly is that tricing line 9 and induction pulley 24 are rotated synchronously, and last example is exactly the ratio that keeps 1 pulse cage operation 1cm.

3. each cage is got back to ground, and electronic counting is with regard to the self-zeroing pulse, to eliminate operating accumulated error.

In sum, induction installation E compares with B, and structure is complicated, also meticulousr, is unfavorable for low quality workman operation, but floor stopper is preset in the electronic impulse that can use the current at present this paper of use to mention in background technology, and certain practicality is arranged.

Three, Fig. 4 be Yi draw increase again on gig traction wheel 5 and the head sheave 8 tricing line 23 replace among Fig. 1 tricing line 9 stop coating control method, this tricing line 23 also equally ties up to cage 7 and counterbalanced weight 15 centres with tricing line 9 in fact, and walk around a deflection sheave and head sheave 8, turn to pulley and traction wheel 5 incorporated in Fig. 4, its essential characteristic and Fig. 1 structural principle do not change.As shown in the figure, on tricing line 23, can load onto equally and prick a fork type induction installation B or inductive switch bundle hair style induction installation D, or induction rotating disc type induction installation E.This method is applicable to that the Yi that redesign is made draws the formula gig, just adds a sipes during design on traction wheel 5 and head sheave 8, with by tricing line 23 and prick first-class, because 23 of tricing line are born control action, do not bear pulling force, tension force is little, so race is wide with slip-off preventing.To install additional on the gig or reequip be unpractical if drawn at the ten million platform Yi that uses at present, trouble and expense height, want once that Yi is drawn several steel ropes of formula gig got a wherein row culture tricing line usefulness, this will weaken the Yi gravitation that Yi draws gig, be infeasible.Having the special-purpose control of tricing line of increase only is feasible solution, but this method also has a shortcoming, make the building ground not want that adopting the gig of architecture storey is not can not once set up the height of wanting architecture storey last yet, for example the building may be set up lift carriage for the first time and has only 20 meters high for high 35 meters, building Gao Shizai to floor increases, it is the things that bother that the rising raising legs is adorned several steel ropes, a lot of rackers mention and just feel tired, in addition add a tricing line now again, so may very not be willing to use.

Four, take a broad view of the method that above various use tricing line is stopped layer control, select relatively with following principle:

1. to be applicable to that Yi any type, newly-designed or old draws formula and carries Rise machine (the tractor quantity of old present use is very huge).

2. dependability, anti-dust, concrete coagulation, the dead ability of rust.

3. easy for installation.

4. the parts that damage are checked, observe, judged to maintenance () easily easily.

5. the manufacturing cost expense is low.

By above principle relatively still with Fig. 1 install tricing line additional and prick a fork type inductive switch comparatively practical, reliability is expensive also low, is the value that popularization is arranged very much.Selecting its scheme to also have the more important is that all devices are all near the ground below cage, cage mass transportation cement wash, sandstone etc., all fall down as raining every day, device is easy to be fallen into oblivion, should be with the constantly movable bundle fork type inductive switch scheme of parts with the ability that anti-cement dust floods.

The utility model is simple and practical, adjusts and keeps in repair easily, and no particular component is fit to vast building ground and uses, and adds that cost is low, and is safe and reliable, is the value that popularization is arranged very much.
