Description
Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to a compact elevator car structure. Background Art
[0002] At present, my country's social economy is developing rapidly, and multi-story buildings are generally equipped with vertical lift elevators, referred to as vertical elevators. With the implementation and promotion of the new national standard 2020 "Safety Specification for Elevator Manufacturing and Installation", in the actual design and application process, it is often encountered that under the limited civil engineering dimensions, the conventional car structure is difficult to meet the minimum car area requirements required by the new national standard.
[0003] The current mainstream economical door machine structure in the market requires the front car wall thickness to be at least 80mm to meet the door machine installation space requirements; however, the new national standard clearly states that when the front car wall thickness is less than or equal to 100mm, the floor area should not be included in the effective area of the car, that is, the 80mm floor area should not be included in the effective area of the car. Therefore, how to meet the installation space requirements of economical door machines and increase the effective area of the car has become a difficult problem. Utility Model Content
[0004] In order to make up for the above-mentioned shortcomings, the utility model provides a compact elevator car structure, which can increase the effective area of the car without sacrificing the installation space of the door machine.
[0005] The utility model is realized through the following technical scheme: a compact elevator car structure, including a car, a lintel and a door machine arranged on the front side of the car, the car including a car top, a car bottom, a front car wall, a rear car wall, a left car wall and a right car wall, characterized in that: a car wall recess for preventing interference with the door machine is arranged at the upper position of the left car wall and the right car wall near the leaf door side, and the shape of the car wall recess is a right-angled trapezoid; the lintel is a folding panel corresponding to the shape of the car wall recess, the upper part of the folding panel is provided with an upper folding edge for connecting with the car top, and the lower part of the folding panel is provided with a lower folding edge for connecting with the front car wall.
[0006] Furthermore, reinforcing rods for connecting with the left and right car walls are arranged at both ends of the folding panel.
[0007] Furthermore, the included angle of the car wall recess is 140°-150°.
[0008] Furthermore, the thickness of the front car wall is 25 mm.
[0009] Furthermore, oblong holes for cooperating with bolts are arranged on the upper folding edge and the lower folding edge of the folding panel.
[0010] Furthermore, an oblong hole for cooperating with a bolt is provided on the reinforcing rod.
[0011] Beneficial effects and features of the utility model:
[0012] The utility model forms a concave cavity that can accommodate the space requirement for door machine installation by connecting the left and right car walls with car wall recesses and the folding panel lintel structure that matches the structure, thereby solving the space requirement for door machine installation.
[0013] By adding notches to the upper left and right car walls, the lower middle part extends outwards to the door leaf side, effectively increasing the available area of the car. This design reduces the thickness of the front car wall (from the traditional 80mm to 25mm), not only meeting the space requirements for door machine installation, but also increasing the effective area of the car equivalent to 55mm thickness, greatly improving the passenger experience.
[0014] The reinforcing rods added at both ends of the folding panel not only enhance the stability of the connection with the left and right car walls, but also simplify the installation and disassembly process of the folding panel and the reinforcing rods by setting oblong holes for cooperation with bolts, thus greatly improving the maintenance efficiency and maintainability of the structure.
[0015] Through the above design, a concave cavity is formed that can accommodate the door machine installation requirements. The effective area of the car corresponding to the distance extended outward by the left car wall and the right car wall becomes the main advantage of the utility model compared with the prior art.
