Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of elevators, and in particular to an elevator car. Background Art
[0002] The elevator car is the part of the elevator system that directly carries passengers or goods. It is the most intuitive component in the entire elevator system and the one that interacts with users most frequently. The car is usually composed of a frame, car walls, car doors, and floors. Traditional cars are mostly regular rectangles (such as the attached Figure 1 As shown in the figure, the size of the car is limited, which makes the elevator load smaller, especially in special environments such as hospitals, where the shaft space is limited and cannot be easily expanded. So when the current elevator car needs to transport a flat car carrying patients, the flat car occupies a large amount of space, making it difficult for medical staff and other accompanying personnel to gain a foothold in the car, leaving very little space for medical staff and accompanying personnel, making it extremely inconvenient to use. Summary of the invention
[0003] The present invention is intended to provide an elevator car to solve the problem that the shaft in the hospital cannot be expanded, limiting the size of the car and causing inconvenience for medical staff to stand when carrying patients on a flat car.
[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: an elevator car, comprising a car frame, a bottom plate, a top plate, a car door and a car wall;
[0005] The top plate and the bottom plate are fixedly mounted on the car frame, and the edges of the top plate and the bottom plate extend to the surroundings to a distance of 5-10 cm from the shaft wall of the elevator shaft. A plurality of notches are left at the edges of the top plate and the bottom plate, and the notches on the top plate are located directly above the notches on the bottom plate and correspond one to one. The notches are used to avoid the car guide rails or the counterweight system during the operation of the car to avoid collision; the car wall is fixedly connected between the top plate and the bottom plate.
[0006] Working principle and beneficial effects of the present invention:
[0007] In this solution, the top plate and bottom plate of the elevator car are extended toward the wall of the elevator shaft, and the idle space in the elevator shaft is used to increase the bottom plate area of the elevator car, thereby expanding the area of the elevator car. The edges of the top plate and the bottom plate are extended 5-10 cm from the wall of the elevator shaft to the surroundings, and sufficient safety distance required for the elevator car to run in the shaft is retained. Therefore, standing space is increased on the basis of the original rectangular car. After the medical staff pushes the flatbed car carrying the patient into the elevator car, the flatbed car occupies the space in the traditional car, and the medical staff can occupy the increased space.
[0008] 1. This solution uses the idle space in the shaft when the shaft space is limited and cannot be easily expanded, and increases the effective use area of the car without changing the overall size of the shaft. For special scenarios such as hospitals, when transporting flat cars carrying patients, medical staff and accompanying personnel have more standing space, solving the problem of insufficient space in traditional cars that makes it difficult for people to stand, and improving the convenience and comfort of elevator use.
[0009] 2. After the car area is expanded in this solution, the load capacity of the elevator can be effectively increased. It is not only limited to solving the problem of standing space for personnel, but also can provide more space options when transporting some larger-sized goods, thereby improving the use efficiency and scope of application of the elevator.
[0010] 3. This solution does not rely on large-scale modification of the shaft and is applicable to a variety of existing shaft structures, especially in places with limited shaft space such as hospitals. It can optimize and upgrade the elevator car without changing the basic structure of the shaft. It has good versatility and adaptability and can be widely used in various scenarios that require increased car space.
[0011] Furthermore, the extensions of the top plate and the bottom plate are both rectangular in shape. The purpose is that, through this arrangement, the distance between the edge and the inner wall of the shaft can be kept the same, so that the elevator car can run stably; and the rectangular extension is conducive to forming a space for medical staff to stand.
[0012] Furthermore, the right angles of the extended part of the bottom plate are chamfered to avoid forming sanitary dead corners, facilitate cleaning and disinfection, and prevent the wheels or corners of the flat car from getting stuck or colliding with the right angles of the bottom plate when the flat car enters and exits the car or parks in the car, making the flat car move more smoothly, facilitating the operation of medical staff, and improving transportation efficiency.
[0013] Furthermore, a handrail is fixedly connected to the inner wall of the elevator car, and the handrail is located just above the extended part of the bottom plate, with a height of 1.5-1.8 meters. The purpose is to provide a grip for medical staff standing on the extended part, thereby avoiding the problem of unstable standing caused by the narrow standing space. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a cross-sectional view of a conventional elevator car from above;
[0015] Figure 2 The present invention is a cross-sectional view of an elevator car viewed from above. DETAILED DESCRIPTION
[0016] The following is further described in detail through specific implementation methods:
[0017] The reference numerals in the drawings of the specification include: elevator shaft 1, car wall 2, bottom plate 3, car guide rail 4, extension part 5, and notch 6.
[0018] The embodiment is basically as shown in the attached Figure 2 As shown:
[0019] An elevator car comprises a car frame, a bottom plate 3, a top plate, a car door and a car wall 2;
[0020] The top plate and the bottom plate 3 are fixedly installed on the car frame, and the edges of the top plate and the bottom plate 3 extend to the surroundings to 5-10 cm away from the shaft wall of the elevator shaft 1. The extension parts 5 of the top plate and the bottom plate 3 are both rectangular, and the right angles of the extension parts 5 of the bottom plate 3 are chamfered. A plurality of notches 6 are left at the edges of the top plate and the bottom plate 3, and the notches 6 on the top plate are located directly above the notches 6 on the bottom plate 3 and correspond one to one. The notches 6 are used to avoid the car guide rails 4 or the counterweight system during the operation of the car to avoid collision; the car wall 2 is fixedly connected between the top plate and the bottom plate 3, and a plurality of handrails are fixedly connected to the inner wall of the elevator car, and the plurality of handrails are respectively located directly above the extension parts 5 of the bottom plate 3, and the height of the handrails is 1.5-1.8 meters.
[0021] The specific implementation process is as follows:
[0022] Taking the counterweighted medical elevator as an example, in this solution, the top plate and bottom plate 3 of the elevator car are extended toward the wall of the elevator shaft 1, and the idle space in the elevator shaft 1 is used to increase the area of the bottom plate 3 of the elevator car, thereby expanding the area of the elevator car, and the edges of the top plate and bottom plate 3 are extended 5-10 cm from the wall of the elevator shaft 1 to the surroundings, retaining the sufficient safety distance required for the elevator car to operate in the elevator shaft 1. Therefore, the standing space is increased on the basis of the original rectangular car. After the medical staff pushes the flat car carrying the patient into the elevator car, the flat car occupies the space in the traditional car, and the medical staff can occupy the increased space.
