Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to a car frame for an elevator. Background Art

[0002] An elevator is a permanent transport device serving specific floors within a building, with its car running on at least two rigid rails perpendicular to the horizontal plane or inclined at an angle of less than 15° to the vertical. In existing elevator technology, dual-rail elevators are widely used due to their simple structure and low cost. However, dual-rail elevators have shortcomings in terms of operational stability and load-bearing capacity, especially when operating at high speeds or carrying heavy loads, resulting in poor car stability. While four-rail elevators offer improved stability and load-bearing capacity, their guide rails are typically located on both sides of the car, resulting in a larger area occupied by the elevator shaft and affecting the efficiency of the shaft space. Furthermore, to ensure sufficient structural strength, a car frame is installed outside the car. The separate structure of the elevator car and frame enhances safety but also limits the car's volume, resulting in a relatively small interior space, which is detrimental to passenger comfort and passenger capacity. Therefore, the present invention proposes an elevator car frame that offers excellent stability and load-bearing capacity, effectively utilizes shaft space, and maintains a sufficient car volume.

[0003] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] As a preferred technical solution of the present invention, the cross section of the column is a wedge-shaped structure, and the cross sections of the cross beam, long beam and short beam are all U-shaped structures.

[0006] As a preferred technical solution of the present invention, the short beams are symmetrically arranged on both sides of the long beam, and the two are perpendicular to each other to form a cross structure, and the ends of the cross structure formed by the long beam and the short beam are respectively abutted on four columns.

[0007] As a preferred technical solution of the present invention, a reinforcing beam is fixed between the long beam and the short beam.

[0008] As a preferred technical solution of the present invention, support rods are fixed between the multiple beams between adjacent columns.

[0009] As a preferred technical solution of the present invention, the frame structure is made entirely of high-strength steel.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention effectively improves the stability and load-bearing capacity of the elevator car by arranging four high-strength structural steel columns as vertical supports of the elevator frame. The integrated structure of the car body and the car frame not only simplifies the structure and reduces the cost, but also increases the internal space of the car, while reducing the occupation of the shaft space, improving passenger comfort and the passenger capacity of the elevator; the guide shoes are installed on the four columns to ensure the four-rail operation of the car, improve stability, further enhance the load-bearing capacity of the car, and ensure the safe operation of the elevator.
