For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The asynchronous counterweight energy-conserving elevator of polylith comprises car, counterweight and driver train, and described counterweight includes several clump weights, and clump weight is separately positioned on the counterweight selection case that is positioned at the building top; Counterweight selects to be provided with in case the controller for allotment clump weight gross weight, the input end connection of controller is arranged on the bottom of car for detection of the weight sensor of car load-carrying, the mouth of controller selects the counterweight adjusting mechanism in case to select clump weight by being arranged on counterweight, and clump weight keeps balance by mechanical transmission mechanism and car.
The concrete structure of mechanical transmission mechanism described in the utility model is: described mechanical transmission mechanism comprises the gear main shaft that is driven by driver train, and the gear main shaft stretches out counterweight and selects an end of case to connect the top of car by hawser; Counterweight is selected also to be provided with the some countershafts parallel with the gear main shaft in case, and described countershaft is positioned at counterweight and selects an end interference fit of case that the gear that is meshed with the gear main shaft is arranged, and countershaft stretches out counterweight and selects an end of case to connect clump weight by hawser; Described counter shaft gear and gear main shaft change engagement by counterweight adjusting mechanism.
Owing to having adopted above technical scheme, the obtained technological advance of the utility model is:
The utility model adopts the combined mode of polylith counterweight, can allocate flexibly the counterweight total weight according to the different load-carryings of car, make elevator in operational process, it is minimum that weight difference between car and counterweight reaches, thereby realize the reliable and stable operation of elevator, both extend the service life of elevator, improved safety performance, reduced again electric energy loss.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structured flowchart of the utility model control system.
Fig. 3 is existing elevator structure schematic diagram.
Wherein: 1. car, 2. counterweight, 21. clump weights, 3. driver train, 4. counterweight is selected case, 5. controller, 6. weight sensor, 7. counterweight adjusting mechanism, 8. mechanical transmission mechanism, 81. gear main shafts, 82. countershafts.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
The asynchronous counterweight energy-conserving elevator of polylith, its structure comprise car 1, counterweight 2 and counterweight selection case 4 as shown in Figure 1.Counterweight selects case 4 to be fixedly installed on the top of building, is used for the counterweight according to the corresponding weight of load-carrying selection input of car.
The top of car 1 connects counterweight by hawser and selects case 4, and the bottom of car is provided with weight sensor, and for detection of the load-carrying of car, the signal end of weight sensor connects counterweight and selects case 4.Counterweight 2 includes several clump weights 21, and clump weight 21 connects counterweight by hawser and selects case 4.
Counterweight is selected to be provided with controller 5, driver train 3, counterweight adjusting mechanism 7 and mechanical transmission mechanism 8 in case 4.The input end of controller connects the signal end of weight sensor, and the mouth of controller is connected with counterweight adjusting mechanism with driver train 3 respectively and is connected, driver train 3 and counterweight adjusting mechanism 7 respectively with mechanical transmission mechanism 8.
Mechanical transmission mechanism comprises rooted tooth wheel main shaft 81 and some countershafts 82, and the quantity of countershaft 82 is corresponding with clump weight quantity.The gear main shaft is positioned at counterweight and selects an end of case 4 to drive rotation by driver train, and gear main shaft 81 stretches out counterweight and selects an end of case to connect the top of car 1 by hawser; The gear main shaft is used for forward or reverse under the order of controller, thereby realizes moving up and down of car.Countershaft 82 all with the gear main shaft be arranged in parallel, and countershaft 82 is positioned at counterweight and selects an end interference fit of case that gear is arranged, and counter shaft gear is meshed with the gear main shaft, and countershaft stretches out counterweight and selects an end of case to connect clump weight 21 by hawser; Countershaft is used for counter-rotating or forward under the effect of gear main shaft, moves downward or upward thereby drive clump weight.
In the utility model, counter shaft gear and gear main shaft engagement change by counterweight adjusting mechanism, also namely under the order of controller, counterweight adjusting mechanism selects the countershaft at suitable clump weight place to be meshed with the gear main shaft, thereby reaches the purpose that counterweight and car are complementary; The countershaft at other not selecteed clump weights place gear main shaft is separated and is failure to actuate.
Do following narration with reference to 2 pairs of principle of work of the present utility model of figure.
When the passenger need to rise, controller was according to rising signals command driven mechanism action, the further driven wheel main shaft of driver train forward, and car is upward movement in the process of gear main shaft forward just.After entering certain floor, the passenger enters car, in car, load-carrying increases, this moment, weight sensor passed to controller with the signal of monitoring, after controller is analyzed judgement, select suitable clump weight, and control with the corresponding counter shaft gear of clump weight of selecting by counterweight adjusting mechanism and be meshed with the gear main shaft, other and not selecteed clump weight countershaft are separated with the gear main shaft; This moment, the load-carrying of counterweight and car matched, and in the time of gear main shaft forward, drives the countershaft counter-rotating, thereby the clump weight of coiling on countershaft is transferred, and reached the purpose that car load-carrying and counterweight gross weight are complementary.
Counterweight select the setting of case reduced between car and counterweight of poor quality, improved the operation stability of elevator in operational process, avoided the portion of energy waste, energy-saving effect is preferably arranged.In addition, because counterweight and car load-carrying are complementary, drag the moment of draging part thereby reduced elevator, extend the elevator life-span.When elevator is dragged the speed recruitment that has also reduced decline unit height car when draging partial failure due to the counterweight effect, and then strengthen the safety performance of elevator.
