Abstract
The invention belongs to the technical field of elevators and discloses an elevator with the variable load capacity and an overload operation method thereof. The elevator with the variable load capacity comprises an elevator control device. The elevator control device comprises a speed control unit and an alarm control unit. When the load of the elevator is larger than the rated load, the operation speed of the elevator is decreased through the speed control unit, and the alarm control unit gives an alarm to limit the weight value from increasing. The elevator can meet the demand of conveying objects exceeding the rated carrying rule without the need of increasing the area of a car, and the building cost is greatly lowered.
Description
Technical field
The invention belongs to elevator technology field, particularly the variable elevator of a kind of load-carrying capacity and overload operation method thereof.
Background technology
Existing elevator be the fixing structure of payload ratings and command speed.Because some high-rise buildings need the object transporting some heavier mass, so the payload ratings of elevator needs the larger of setting.
See accompanying drawing 1, consider the principle of elevator, the payload ratings (Q) that counterweight 1 quality is generally 1/2 adds the quality (P) of car 2.When elevator payload ratings becomes large, the mass deviation on its both sides is larger, and energy consumption during no-load run is higher.And consider requirement about assembled passenger elevator car area in elevator national standard, when load-carrying is larger, its car 2 area required is larger, and corresponding hoistway 3 building area just requires larger, and building cost is higher.
Therefore, existing elevator is merely able to the transportation demand meeting command speed payload ratings, when needing handling load quality to exceed the payload ratings of elevator, just needs the elevator of configuration one more large gauge.Because the car area of large gauge elevator must strengthen, so just cause building cost and uprise, and consider that the load-carrying of elevator is larger, the quality of elevator self is also larger, and the power that elevator runs to command speed needs is also larger.And when elevator loading becomes large in addition, the mass deviation on its both sides also becomes large thereupon.When considering that elevator runs, be all not full-load run under most of operating mode, the waste of energy when so just causing elevator to run.And work as power one timing of elevator, it cannot meet the user demand of high speed heavy－duty simultaneously, can only be partial to some extent.Such as when elevator is heavy－duty, its speed must lower.Be difficult to realize inside same elevator, the conversion of high speed light loading and low-speed heave-load.
Summary of the invention

(3) transporting cargo completes;
(4) by described function button, elevator is switched to normal condition, elevator speed is returned to normal value by described speed control unit, and maximum weight is returned to normal value by described alarm control unit.
Further, before described (1) step, comprise the authority that operating personal needs obtain the described function button of operation.
The overload operation method of the variable elevator of another kind of load-carrying capacity, comprises the steps:
(1) be arranged on counterweight by additional counterweight in elevator hoistways, described trigger switch triggers, and elevator speed is down to preset value by described speed control unit, and maximum weight is increased to preset value by described alarm control unit;
(2) transporting cargo is loaded elevator;
(3) transporting cargo completes;
(4) unloaded from counterweight by additional counterweight in elevator hoistways, described trigger switch resets, and elevator speed is returned to normal value by described speed control unit, and maximum weight is returned to normal value by described alarm control unit.
Further, before described (one) step, comprising operating personal needs acquisition operation to enter the authority of the additional counterweight of hoistway operation.
The invention has the beneficial effects as follows:
Do not need the area size increasing car, just can ensure that elevator meets the needs transporting and exceed the article of specified loading instruction, greatly lower building cost.
