Description

Combined multi-car elevator system

Technical Field

The invention belongs to the technical field of elevators, and particularly relates to a combined multi-car elevator system.

Background

Elevators have become an indispensable manned or cargo vertical transport vehicle in modern society and economic activities. Since 1854 the invention of elevators, elevator cars have been operated by wire rope sheave traction drive, and machine rooms, traction motors and reduction gears were installed on the top floors of buildings to drive wire ropes to pull the cars and counterweights to operate on rails in the hoistway. The driving mode enables only one elevator car to normally run in a single shaft, and the elevator in the single-elevator-car running mode can meet the use requirement on low-rise buildings and floors with small passenger flow. With the rapid development of modern cities, high-rise buildings and super high-rise buildings with large population density are pulled out, the defects of long elevator waiting time and low conveying efficiency of the elevator in a single-car operation mode are continuously enlarged, and the traditional single-car elevator operation mode is difficult to adapt to the rapid development requirements of modern city buildings.

In order to improve the building space utilization rate and the elevator conveying efficiency and reduce the construction cost of the building and the elevator, a multi-car parallel elevator is being developed and applied along with the continuous development of the engineering technology level. The multi-car parallel elevator adopts the direct drive technology without the traction steel wire rope, so that a plurality of elevator cars can be operated simultaneously in the same shaft, and the elevators among the shafts can be switched to operate in the shafts, so as to realize the overrunning operation.

Residential elevators have a need to accommodate stretchers, furniture, or other large-sized cargo. For a traditional steel wire traction elevator system, an elevator with a car size larger than that of a common passenger elevator car is usually independently equipped for carrying a stretcher, furniture or other large-size goods, the size of the car is increased, and the size requirement on an elevator shaft is also increased.

However, for a multi-car elevator, if a car with a size larger than that of a common passenger elevator is separately equipped, the size of a hoistway through which the car runs is larger than that of the common passenger elevator hoistway, which results in increasing the size of the hoistway, wasting hoistway resources, increasing manufacturing cost, and reducing the flexibility and traffic efficiency of car switching of the multi-car elevator system.

Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

A combined multi-car elevator system, as shown in fig. 1 and 2, includes a plurality of cars 4, at least two main rails 3, and a plurality of switching rails for joining two different main rails 3, the switching rails and the main rails 3 being collectively referred to as rails. The elevator system further comprises a driving device, a suspension device and a guiding and limiting device, wherein the driving device, the guiding and limiting device and the car 4 are all installed on the suspension device, the driving device drives the suspension device and the car 4 to move upwards or downwards along the main track 3, and the car 4 is switched to different main tracks 3 through switching tracks. I.e. the elevator has no hoisting structure and the car 4 is not driven by the hoisting ropes but by the drive means.

The main track 3 and the switching track are installed in the hoistway 2. In the technical scheme, at least two main rails 3 which are arranged in parallel at intervals are arranged in one shaft 2, and a car 4 to be combined is positioned in the shaft 2. Preferably, two cars 4 on two adjacent main rails 3 in one hoistway 2 are combined, and the two cars 4 to be combined can be communicated with each other after being combined.

The elevator system also includes a ganged interlock 4-1, a panel storage area 4-3, and a plurality of guards 4-2.

Two ends of the linkage interlocking device 4-1 are respectively detachably connected with two cars 4 to be combined. After the two cars 4 are connected by the linkage interlocking device 4-1, the bottom plates of the two cars 4 are positioned in the same horizontal plane and are connected by the linkage interlocking device 4-1 to form a combined car whole which moves up and down along the two main rails 3. The linkage interlocking device 4-1 can ensure that dislocation and shearing accidents can not occur in the running process of the two combined cages 4. The linkage interlocking device 4-1 can be a safe interlocking pin shaft, two adjacent cars 4 are provided with shaft holes, and the linkage interlocking device 4-1 can detachably connect the two cars 4 through the shaft holes.

At least one side wall of the cars 4 is openable, and after the side walls of the two cars 4 to be combined, which are closest to each other, are opened, the two cars 4 are communicated to form a channel, and the formed channel is a long-strip-shaped space. The connected passages can accommodate a larger size of cargo 5 than a single car 4. The side wall opening mode is detachable or foldable or movable. Preferably, for two cars 4 to be combined, one side wall of each car 4 is detachable or foldable or movable, the detachable or foldable or movable side wall being the side wall of this car 4 closest to the other car 4.

The detachable side wall means that the side wall is integrally detached, and the side wall can be a whole flat plate or formed by splicing a plurality of flat plates. When the single car 4 runs, the side wall is installed on the car 4 by means of screws or clamping connection and the like. When it is desired to combine the car 4 with the car 4 on the adjacent main rail 3, the side walls are removed. When the side wall is dismantled, if the side wall is a whole flat plate, the whole flat plate is dismantled, and if the side wall is formed by splicing a plurality of flat plates, the flat plates are dismantled one by one.

The side wall is movable, which means that the side wall can be opened in other ways than being detached and folded, for example, the side wall can be similar to a vertical hinged door, and the side wall is connected with the car 4 through a hinge, and when the side wall is opened, the side wall rotates around the hinge.

The panel storage area 4-3 is used to store and accommodate the side walls after disassembly or folding. The panel storage area 4-3 may be located on one side of the space between two cars 4 to be combined or within one car 4. When the side walls are foldable, it is preferred that the panel storage area 4-3 is located on one side of the passageway between the two cars 4 to be combined. When the side wall is detachable, the detached side wall can be moved out of the car 4, or the wall plate storage area 4-3 is arranged on the rear wall of the car 4, so that a larger passing space of the combined car channel is ensured, the size of a well is not increased, and the effective size in the car is not influenced.

The elevator system also has a plurality of protective devices 4-2, and after the side walls are opened, the bottom plates of the passages formed by the two cars 4 to be combined are connected through the protective devices 4-2, namely the bottom plates of the two cars 4 to be combined are connected through the protective devices 4-2. The two sides of the passage formed by the two cars 4 to be combined are connected by the guard 4-2, or the front walls of the two cars 4 to be combined are connected by the guard 4-2 and the rear walls are also connected by the guard 4-2. The front wall refers to a car wall surface provided with a car door, and the rear wall refers to a car wall surface opposite to the front wall. The openable side wall is a left side wall or a right side wall. The shielding means 4-2 is detachably arranged. When the panel storage area 4-3 is located at one side of the passage between two adjacent cars 4, the area where the panel storage area 4-3 is located may not be provided with the guard 4-2. The guard 4-2 can prevent objects from falling from the space between two adjacent cars 4 or people from stepping empty.

The working process of the invention is as follows: when the elevator needs to transport goods 5 such as stretchers, furniture and the like, and the size of the goods 5 is larger than the maximum size that can be accommodated by a single car 4, two cars 4 on two adjacent main rails 3 in one hoistway 2 are selected as the cars 4 to be combined. First, the side walls of the two cars 4 closest to each other are removed or folded to connect the two cars 4 to each other to form an elongated space that can accommodate larger cargo 5. Then, the two cars 4 are connected and locked by the linkage interlocking device 4-1, at the moment, the two cars 4 realize linkage, and after the connection, the bottom plates of the two cars 4 are positioned on the same horizontal plane. Next, the goods 5 to be transported in the waiting hall 1 are moved from one car 4 into the two cars 4 after combination, so that the size of the goods 5 is adapted to the space communicated after combination, as shown by the moving process of the goods 5 in the dotted line in fig. 1 and 2. The two cars 4, when combined, are operated only on their respective main tracks 3 in synchronism with each other and not on the switching tracks. When the elevator does not need to transport large-size goods such as stretchers, furniture and the like, and the space of a single car 4 can meet the transportation requirement, the linkage interlocking device 4-1 is removed, the linkage interlocking effect of the linkage interlocking device 4-1 on the two cars 4 is cancelled, then the protection device 4-2 is removed, and the wall doors of the cars 4 which are closest to each other are installed again, so that the two cars 4 are recovered to be in independent states.

Thus, when heavy, oversized, or heavy-weight goods 5, such as heavy goods, stretchers, large furniture, etc., need to be transported, at least two of the cars 4 may be combined to form an elevator system suitable for transporting such goods 5. And the proportion of the time for transporting large-size goods to the total running time of the elevator is small, so that the requirement for transporting large-size goods is met on one hand, and the overall structure and the running efficiency of the elevator system are not influenced on the other hand by the mode of combining the cars 4.

Finally, it must be said here that: the above embodiments are only used for further detailed description of the technical solutions of the present invention, and should not be understood as limiting the scope of the present invention, and the insubstantial modifications and adaptations made by those skilled in the art according to the above descriptions of the present invention are within the scope of the present invention.
