Detailed Description

The present invention will be described in detail with reference to fig. 1 to 7, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solution of the present invention will be further described in detail in conjunction with fig. 1 to 7. The specific implementation mode is as follows: the utility model relates to a one-to-two type quick safe energy-saving elevator, wherein the basic structures of an electric traction system, a guide system, a car and door system, an intelligent electric control system, a safety protection system, an upper and lower selection panel, a floor indication screen and the like are the same as those of a conventional elevator; the improved or improved device comprises a driving chain 1, two driving chain wheels 2, a special power driver 3, a weight self-balancing system, two reinforced safety protection steel wire ropes 4, four guide rope wheels 5, a direction guide screen and voice prompt combiner 6 and the like. The double-drive type elevator is characterized by a one-drive-two type operation mode, namely, an electric traction machine simultaneously drives two cages to synchronously operate alternately one on top of the other through a special power driver 3, two driving chain wheels 2 and a driving chain 1. The number of transmission shafts of the special power transmission device 3 is odd (generally designed to be 3 or 5 due to the limitation of machining size and precision and the consideration of reducing manufacturing cost), the gear transmission ratio is 1, the power input shaft is an intermediate shaft, and the power output shaft is the outermost shaft on two sides. Two driving chain wheels 2 are assembled on the power output shaft of a special power transmission 3 in groups. The driving chain 1 is meshed with the two driving chain wheels 2, two ends of the driving chain are respectively connected to the middle positions of the tops of the two cars, and the effective length of the driving chain 2 just ensures that one car runs at the topmost end of a floor and the other car reaches the lowest end of the floor. The weight self-balancing system is that two cages are mutually balanced without additional balance weights, the self weight of a single cage is equal to or slightly larger than the rated load, and then the balance coefficient of the novel elevator is fixedly designed to be 0.5. The four guide rope wheels 5 are divided into two groups, two driving chain wheels 2 are respectively arranged on two power output shafts, and two guide rope wheels 5 of the same group are respectively arranged on two sides of the driving chain wheels 2. Through direction rope sheave 5, the top at two cars is connected respectively at two strenghthened type safety protection wire rope 4's both ends, and wire rope 4 equals with drive chain 1's effective length, and the pitch circle diameter of direction rope sheave 5 equals with drive sprocket 2's reference circle diameter to ensure the absolute safety and the steady of elevator operation. The direction guide screen and voice prompt combiner 6 is designed and installed on the upper and lower selection panels, and for a novel elevator in a side-by-side application mode, only one set of direction guide screen and voice prompt combiner 6 is designed and installed in the middle position of two elevator doors of each floor; for the novel elevator in the face-to-face application mode, a set of direction guide screen and voice prompt combiner 6 is designed and installed beside each elevator door of each floor. After the intelligent electric control system receives the command of passengers going upstairs or downstairs, the technical scheme which is the fastest is calculated at the first time, and the direction guide screen and voice prompt combiner 6 guides the passengers to move to the left or move to the right to wait for the elevator car; or to guide the passenger to either continue in place at the doorway or to travel to another doorway to wait for the car to come so that the passenger can ride on the elevator within half the cycle time. The direction guide screen can flash a green light in the shape of O, a red light or a green guide light in the shape of I, the green light in the shape of O flashes the waiting on site, the red light in the shape of O flashes the door not open, the green light in the shape of I flashes the left side or the right side or the other car door, and the voice prompter sends out the sound of waiting, the left side or the right side or the opposite side to bring convenience to the passengers to the maximum extent.

Compared with two conventional adjacent elevators, the novel elevator group reduces one electric traction machine, one speed reducer, one set of electric control system and two balance weights, and also reduces the area and space of a well and a machine room, so that the equipment cost is reduced, the construction investment is saved, and the electric energy consumption can be reduced. Because novel elevator adopts one-on-one synchronization, operation mode in turn, can effectively reduce the return air rate and save passenger waiting time, when different passengers select "go up" and "down" simultaneously, novel elevator more can exert swift and energy-conserving advantage. If the load of the descending car is larger than that of the ascending car, the novel elevator can still make full use of potential energy difference and can realize operation only by providing a small amount of starting energy consumption, so that the energy-saving effect is more obvious.

When taking novel elevator, wherein one side car has arrived appointed floor, and the car of another side has not arrived appointed floor yet, for preventing passenger misjudgement and guarantee safety, necessary technical solution does, except that the suggestion of floor display screen, the key of opening the door of the car of not arriving appointed floor can be deadlocked by the technique, and voice prompt in the floor display screen sends the sound of "please wait" simultaneously in order to remind the passenger.

Fig. 3 is a schematic view of the special structure of the elevator in the side-by-side application mode, i.e. a special power transmission device is omitted, and a large-diameter chain wheel is directly adopted, and the chain wheel is installed on the output shaft of the electric traction machine, and the reference circle diameter of the chain wheel is equal to the horizontal distance between the vertical center lines of the two driving chain wheels. Correspondingly, two large-diameter guide rope wheels are directly designed, and are installed on the output shaft of the electric traction machine together with the chain wheel, the installation positions of the guide rope wheels are respectively arranged on two sides of the chain wheel, and the pitch diameter of the guide rope wheels is equal to the pitch diameter of the large-diameter chain wheel. This particular design has advantages and disadvantages compared to a dedicated power transmission.

If the existing two adjacent old elevators need to be updated, if the original elevator meets certain technical conditions, the new technology can be used for modification, and compared with the conventional modification technology, the new technology can save more expenses.

The application and popularization of the new technology of the one-to-two type quick safe energy-saving elevator are realized, the maximum resistance comes from the original riding habit of passengers, only the propaganda strength and demonstration guidance are increased for the passengers, and the passengers can quickly accept and approve the new elevator and enjoy the quick benefits brought by the new technology when experiencing and using the elevator correctly.
