Description

Technical Field

[0001] The utility model belongs to the technical field of machine room-less passenger elevators, and in particular relates to a machine room-less passenger elevator with high hoistway utilization. Background Art

[0002] A machine room-less elevator is an elevator that does not require a building to provide a closed dedicated machine room for installing elevator drive host, control cabinet, speed limiter and other equipment. The machine room-less elevator is not a simple partial improvement of the traditional elevator in the past, but a major revolution in elevator technology.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: However, the existing machine roomless elevators have the problem of low space utilization in the shaft: the conveying structure outside the car occupies a large space in the shaft, resulting in a large amount of space waste in the shaft; the top space in the shaft is used to install structures such as the traction machine, which takes up a lot of space.

[0004] Therefore, we propose a machine room-less passenger elevator with high shaft utilization to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a machine room-less passenger elevator with high shaft utilization, which greatly reduces the use of the top space of the shaft structure, and the four sides of the car are closer to the inner walls of the four sides of the shaft structure, reducing the waste of the internal space of the shaft structure, greatly improving the space utilization, and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A machine room-less passenger elevator with high shaft utilization rate comprises a shaft structure and an extended shaft portion integrally constructed on one side of the shaft structure. In actual construction, an additional extended shaft portion is constructed on the top of the shaft structure, using the same structure and materials. The inner cavity space of the shaft structure is completely connected to the inner cavity space of the extended shaft portion. A car is running in the inner cavity of the shaft structure in a vertical direction. Two traction machines of equal height and parallel to each other are fixed in the extended shaft portion. The output shaft of each traction machine is coaxially connected to an inner support shaft. A cable barrel is fixedly sleeved on each inner support shaft. Annular cable barrel grooves are formed on both sides of the outer wall of each cable barrel. A cable is fixedly connected in each annular cable barrel groove. There are four annular cable barrel grooves in total, so there are four cables in total. The bottoms of the four cables are all connected to the top of the car.

[0008] Two sets of pulleys are installed on the two opposite side walls of the car, with a total of four sets of pulleys, and each set of pulleys is arranged with multiple pulleys at equal intervals in the vertical direction. Two sliding rails are installed on the two opposite side walls of the inner cavity of the shaft structure, that is, there are four sliding rails in total. The four sets of pulleys run on the four sliding rails respectively, so that the outer wall of the car is closer to the inner wall of the shaft structure, and the sliding rails are embedded in the shaft structure, thereby reducing the occupation of the sliding rails on the inner cavity space of the shaft structure, and further improving the space utilization rate of the shaft structure.

[0009] As a preferred embodiment, a transport space slot is formed on the side of the car facing away from the extended shaft portion, so that people, goods, etc. can enter the transport space slot from the opening of the transport space slot.

[0010] As a preferred implementation scheme, two traction machine brackets of equal height are installed on the bottom wall of the inner cavity of the extended shaft section, and the two traction machines are fixedly installed on the two traction machine brackets respectively; so that the traction machine structure remains stable, and all power structures on the shaft structure and the extended shaft section need to be powered by external designated power facilities.

[0011] As a preferred implementation scheme, the side of the inner support shaft facing away from the traction machine is rotatably connected to the shaft structure; in actual design, a bearing seat can be installed in the shaft structure, and the side of the inner support shaft facing away from the traction machine is installed in the bearing seat, so that the inner support shaft can operate stably.

[0012] As a preferred implementation scheme, slideways are provided on the side of the four sliding rails facing the car, and four sets of pulleys are respectively in contact with the inner walls of the four slideways; so that the four sets of pulleys can roll on the inner walls of the four slideways to ensure the stability of the car during lifting.

[0013] As a preferred embodiment, reinforcing plates are fixedly installed on the side walls of the shaft structure and the bottom wall of the extended shaft portion, and an extension plate is fixed under the reinforcing plates. The reinforcing plates and the extension plates are fixedly connected by multiple sets of bolts; so that the reinforcing plates and the extension plates support and strengthen the structure of the extended shaft portion.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0016] This high-utilization hoistway machine-room-less passenger elevator has four sliding rails embedded in the hoistway structure, reducing the encroachment of the sliding rails on the inner space of the hoistway structure. The inner walls on the four sides of the car, as well as structures such as the traction machine, are all located in the extended hoistway portion, reducing the space occupied by the hoistway structure and increasing the space in the hoistway structure used for car services, thereby improving space utilization.
