Abstract
The utility model relates to a kind of variable-speed elevator control setup, comprise towing machine, counterweight, car and car weighting apparatus, towing machine uses steel rope to connect counterweight and car respectively, car weighting apparatus is arranged in the cavity of cage bottom, car is provided with weight information transmission apparatus, weight information transmission apparatus and car weighting apparatus use connection, and weight information transmission apparatus and towing machine use connection.Car weighting apparatus and weight information transmission apparatus, calculate the real-time weight difference of car counterweight, the power margin of towing machine when utilizing elevator normally to run, and makes the real-world operation speed of elevator can be increased to exceed the level of elevator initial nominal speed.
Description
Technical field
The utility model relates to a kind of variable-speed elevator control setup, belongs to elevator technology field.
Background technology
Generally, elevator design is all select the main frame of corresponding power according to the command speed of elevator under fully loaded or light condition, and in elevator actual moving process, because the number change of passenger, between car and counterweight, gap can be less than zero load or fully loaded state, because the restriction of command speed in traditional elevator, speed is not just improving after reaching command speed, now main frame is not close to full power running, and efficiency is not high.Impact when former building is lower, stop is less is also little, but along with expanding economy, the building of house office is more and more higher, user for the wait time taken required by elevator and riding time also shorter and shorter, the appearance of express elevator and multiple control lift and development are just being used to alleviate this contradiction; But the space resources of building is limited after all, in addition for elevator cost of price, the consideration of each side such as interior construction spacing environment, so on the basis changing original elevator machine electrical structure by a small margin, utilize the power margin of traction main frame in the actual normal operation of elevator, real-world operation speed under raising elevator normally works, shortens time of run, and actv. improves elevator service level.
Summary of the invention
The technical problems to be solved in the utility model is on car, increase weight information transmission apparatus, weight information transmission apparatus sends the information that car weighting apparatus is collected to towing machine speeds control motherboard circuit, motherboard circuit changes towing machine rotating speed, improves the variable-speed elevator control setup of elevator speed and operating efficiency.
In order to solve the problems of the technologies described above, a kind of variable-speed elevator control setup of the utility model, comprise towing machine, counterweight, car and car weighting apparatus, towing machine uses steel rope to connect counterweight and car respectively, car weighting apparatus is arranged in the cavity of cage bottom, car is provided with weight information transmission apparatus, described weight information transmission apparatus and car weighting apparatus use connection, and weight information transmission apparatus and towing machine use connection.
As preferably, weight information transmission apparatus is arranged in cavity.This structure is not only protected weight information transmission apparatus, also a saving installing space, makes integral installation effect more attractive in appearance.
Further, before car brings into operation, if weighting apparatus detect car loaded weight exceptional value time, car does not run.When cage operation, the car loaded weight detected by weighting apparatus and contrasting based on the car load value that towing machine feedback current calculates, when difference is larger, is reduced to command speed by running velocity, immediately to protect towing machine and actuating device.
After adopting this structure, weight information transmission apparatus calculates the real-time weight difference of car counterweight, on the basis being no more than towing machine power, just can improve the running velocity of towing machine during normal work.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is installation front view of the present utility model.
detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of variable-speed elevator control setup according to Fig. 1, comprise towing machine 1, counterweight 3, car 4 and car weighting apparatus 5, towing machine 1 uses steel rope 2 to connect counterweight 3 and car 4 respectively, car weighting apparatus 5 is arranged in the cavity 41 bottom car 4, car 4 is provided with weight information transmission apparatus 6, weight information transmission apparatus 6 and car weighting apparatus 5 use connection, and weight information transmission apparatus and towing machine 1 use connection.
According to Fig. 1, weight information transmission apparatus 6 is arranged in cavity 41.
During use, when after hall buttons or control wheel button actions, when elevator prepares to run, the car 4 that weighting apparatus 5 collects by first elevator in real time loaded weight information is delivered to weight information transmission apparatus 6, after weight information transmission apparatus 6 is analyzed, according to the parameter set, information is sent to towing machine 1 speeds control mainboard, if weigh, abnormal then elevator can not run, normal if weigh, then select the running velocity adapting to the current loading mass of car 4, the high efficiency that can realize towing machine 1 power uses.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
