Description

Transportation type elevator simultaneously up and down

The utility model belongs to the comprehensive application technology field, relates to a kind of transportation lifting means of innovation, particularly a kind of pair of car, doublestroke, two driving, transportation type elevator simultaneously up and down.

In China, the type of drive of nowadays common high-rise elevator, major part is the traction steel-cable formula, seldom adopt fluid pressure type or spiral or pinion and-rack, singly studying carefully steel wire rope type drives, all be again single car (single loading space), one-stroke and to the operation of recast vertical lift, here weak point is single car, one-stroke, single driving, one-way haul, only brought into play a part of transportation function, and the counterweight shuttle, only absolutely empty do the lifting operation, except being used for failing directly to embody the vertical transport function the part weight of balance car.Yet the transportation function of this part shuttle can develop.Abroad, this shuttle is not fully developed yet, though the elevator in the Eiffel Tower of Paris, two single cars have been adopted, but can only do the operation that settles at one go up and down, a lot of midway stops, two single car flat bed stops simultaneously, this obviously can't satisfy the traffic requirements of high building elevator.The utility model has breakthrough creation to this.

The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, and a kind of pair of car, doublestroke, two driving, transportation type elevator simultaneously up and down are provided.This product can make two two cars from bottom end station along each stop of hoistway to top terminal landing, all coupling station numbers of composition, accurate flat bed is given full play to transportation function simultaneously, increase at double transportation volume, the energy-and time-economizing, simple in structure, steady safety.

The purpose of this utility model realizes by following measure:

The utility model is a kind of transportation type elevator simultaneously that has up and down, it comprises the elevator assembly, it is characterized in that: the two ends of a traction steel-cable (19) of first kind of actuating device, connecting the car frame (1) that second kind of actuating device (7) is housed respectively, be sleeved on two cars of being formed with movable car (2).

The outside of car frame (1), the long guideway (17) that long rail leads in boots (18) and the hoistway (9) is housed to match, and short lead rail (20) is equipped with in the inboard of car frame (1), lead boots (21) with the short rail of movable car (2) outside installation and match, long guideway (17) constitutes the doublestroke space jointly with short lead rail (20).Car frame (1) is equipped with second kind of actuating device of fluid pressure type (7) on the bottom surface, and its operating cylinder (24) is connected with the bottom surface of movable car (2), and second kind of actuating device and first kind of actuating device of traction steel-cable formula have constituted two drive forms jointly.Two all coupling stops that the simultaneously accurate flat bed of two cars is formed, plane on their two landing sills, respectively with the sill at bottom end station on the formed vertical dimension sum in plane, it all is steady state value, differ bigger a pair of stop for indivedual steady state values, establish shipping platform (13) with regard to other, constitute the another kind of sign of coupling stop.From bottom end station (15) and top terminal landing (11), along each station that hoistway is stopped, by up ordinal number in turn, press against time ordinal number with descending, two two stops that two cars are stopped simultaneously, all station numbers of composition spouse all are called " coupling stop ", each coupled layer order of station is counted sum in this building, equals the actual total stop number of this elevator.Two two cars are stopped each coupling stop, are subjected to the macro-control of first kind of actuating device of work of traction steel-cable formula driving, also are subjected to the micromanagement of second kind of actuating device of work of fluid pressure type driving, and two kinds of actuating devices are subjected to accurate flat bed condition automatic guidance.The total quantity of flat bed controlled parameter is 1/2nd of the actual total number of plies of this elevator.The size of each value of flat bed controlled parameter, participate in the adjustment mode with second kind of actuating device and decide, i.e. the two cars of end adjustment value alone is two times of adjustment value of two cars while of two ends, the two cars in two ends are adjustment value simultaneously, when being coupling stop flat bed 1/2nd of diff-H.Thereby the size of all flat bed controlled parameter values, the computer of practical measurement input in advance.In the flat bed process, two kinds of actuating devices are discrete, controlled by sensor, relay, contactless switch and the computer of each several part, two kinds of actuating devices can move simultaneously, also can move respectively, realize macroscopical coarse adjustment, leveling accuracy and operation shortest time are guaranteed in the microcosmic fine tuning.Because two two car frames are respectively the two ends that are fixed on a traction steel-cable (19), except significantly expanding with heat and contract with cold or other reasons causes that its length is unmodified the traction steel-cable distortion.The distance that is raised of A car frame baseplane just, equal the distance that B car frame baseplane is lowered by, above-below direction also is the same by turns, the length of traction steel-cable is nonadjustable, therefore on two landing sills of each coupling stop on plane and the bottom end station sill plane apart from sum, all be steady state value, and should equate.But high-rise building, because each floor utilization difference, each floor is decorated the not equal reason of back sill thickness, often make the accurate flat bed in car frame baseplane of traction steel-cable one end, the car frame baseplane of the traction steel-cable other end is accurate flat bed usually then, and what that is to say on two landing sills of each coupling stop plane on the plane and bottom end station sill inevitably exists diff-H apart from sum.Yet adopt second kind of actuating device (7), make movable car (2) in car frame (1), make the way of last or following operation, the difficult problem in the time of just can solving flat bed.Though traction steel-cable (19) length is unmodified, but the movable car (2) in the two cars in two ends, if operation downwards simultaneously, just reached the effect of traction steel-cable elongation, if upwards operation simultaneously, just reached the effect that traction steel-cable shortens, traction steel-cable elongation and the effect that shortens can realize within the specific limits in a word.When first kind of actuating device flat bed, the circuitous diff-H that arrives, make two movable cars do operation in the same way by second kind of actuating device, each adjusts 1/2nd diff-H, just can realize accurate flat bed.Differ bigger a pair of stop for indivedual steady state values, gesture is forced and can not be stopped simultaneously, can adopt the way that shipping platform (13) are set, and remedying part can not left alone without help communications and transportation function by the floor platform.Because two two car equal and opposite in directions of the present utility model, service direction is opposite, and constitute the symmetrical balance formula, act on load torque on the traction rope sheave so, can only decide with the difference of load-carrying in two two cars, equate with the decline domestic shipping weight that if promote then load torque is zero, in other words very little very little, only overcome the friction resistive torque.For normal maintenance balance or near state of equilibrium operation down, special installing load load-carrying telltale and bearing meter in two movable cars, can inform in time how the passenger increases and decreases the load that promotes or descend, be beneficial to cruising, the left alone without help requirement of sailing or the like of reporting to the police of fully loaded straight, overload (utmost point overbalance) makes passenger mentality be willing to accept, and according to telltale, voluntary observance rule and ordering.When hoisting depth generally about 30 meters, the difference of traction steel-cable weighs and just demonstrates bigger overbalance, be necessary under two two car frames, closed loop tail rope (8) and straining pulley (5) to be installed, the Compositional balance compensating device, making up and down that the transportation type elevator is everlasting simultaneously moves state of equilibrium under, so steadily comfortable, safety and reliability are more outstanding.The self structure that also is two cars has second kind of actuating device (7), movable car (2) is moved in car frame (1), can make the adjustment height of microcosmic, because the lifting of microcosmic or decline, range ability are all very short, so driving power is little, with this little input, difficult problem when having solved the flat bed of each coupling stop has then brought macroscopical transportation function, and the several times relation has more been given prominence in energy-conservation aspect.

The utility model while transportation type elevator advantage up and down is: promoting descends transports the passenger simultaneously, transportation function is brought into play comprehensively, because two two all parts of car, content, shape, material, size, structure are identical, increase the state of equilibrium probability of operation down, given prominence to steady, safe, comfortable performance.In the same specification condition relatively down, the simple expression is: " one is pushed up two ", promptly use a while transportation type elevator up and down, very useful two nowadays commercially available elevators have been saved the space of two counterweight operations again, have increased the usable floor area in building.
