The detachable design between the first L-shaped support plate 3 and the second L-shaped support plate 301 makes it unnecessary to disassemble the entire support structure on a large scale when a component is worn or fails, thereby reducing the complexity and cost of maintenance.

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] Example 1, please refer to Figure 1-Figure 4, a steel belt passenger elevator, comprising a shaft frame 1, wherein two car guide rails 2 are arranged in the shaft frame 1, and a plurality of first fixing members are arranged between the two car guide rails 2 and the shaft frame 1, the first fixing member comprising a first L-shaped support plate 3 installed on the car guide rail 2 and a second L-shaped support plate 301 installed on the shaft frame 1, the second L-shaped support plate 301 and the first L-shaped support plate 3 are detachably connected, the present application can realize the connection between the car guide rail 2 and the shaft frame 1 by setting the first L-shaped support plate 3 and the second L-shaped support plate 301, and the second L-shaped support plate 301 can support the car guide rail 2 through the first fixing plate 302, this design effectively disperses the load during the operation of the car, enhances the supporting capacity of the car guide rail 2, and significantly improves the stability and safety of the elevator operation, the detachable design between the first L-shaped support plate 3 and the second L-shaped support plate 301 makes it unnecessary to disassemble the entire supporting structure on a large scale when a component is worn or fails, thereby reducing the complexity and cost of maintenance.

[0037] Further, such as Figure 2 and Figure 3 As shown, the shaft frame 1 includes four vertical beams 102 arranged vertically, and a plurality of cross beams 101 are fixedly connected between the four vertical beams 102. The cross beams 101 and the vertical beams 102 cooperate with each other to form a stable supporting structure, providing a solid foundation for the entire elevator system. It effectively disperses the weight from components such as the car and counterweight, reduces the pressure on each component, and thus extends the service life of the shaft frame. At the same time, the stable structure can reduce deformation and vibration caused by uneven force, and improve the stability and comfort of the elevator operation.

[0038] Further, such as Figure 4 As shown, the first L-shaped support plate 3 is connected to the car guide rail 2 by bolts, and the second L-shaped support plate 301 is connected to the crossbeam 101 by bolts. The bolt connection is convenient for disassembly and assembly, and it is convenient for replacement when the parts are damaged, which brings great convenience to the installation and replacement of elevator parts. It is not only simple to operate and does not require complicated tools and professional skills, but also has a firm and reliable connection and can withstand various loads generated during the operation of the car. In addition, the detachability of the bolt connection enables rapid replacement when the parts are damaged, which greatly shortens the maintenance time and reduces the maintenance cost.

[0039] Further, such as Figure 3 As shown, the bottom of the car guide rail 2 is connected to a first fixing plate 302 by bolts, and the first fixing plate 302 is connected to the supporting plane by bolts. The first fixing plate 302 can fix the bottom of the car guide rail 2 to improve the stability of the car guide rail 2, enhance the resistance of the car guide rail 2 to lateral forces, and improve the safety of the elevator during operation.

[0040] Embodiment 2 further optimizes the steel belt passenger elevator provided in Embodiment 1. Specifically, Figure 2 , Figure 3 and Figure 5 As shown, two counterweight guide rails 4 are further arranged in the shaft frame 1 , and a plurality of second fixing members are arranged between the two counterweight guide rails 4 and the shaft frame 1 , and the second fixing members are used to connect the counterweight guide rails 4 and the shaft frame 1 together.

[0041] Further, such as Figure 5 As shown, the second fixing member includes a fourth L-shaped support plate 501 installed on the crossbeam 101 by bolts and a third L-shaped support plate 5 installed on the counterweight guide rail 4 by bolts. The third L-shaped support plate 5 and the fourth L-shaped support plate 501 are connected by bolts. The bolt connection facilitates disassembly and assembly, and is convenient for replacement when the components are damaged.

[0042] Further, such as Figure 3 As shown, the bottom of the counterweight guide rail 4 is connected to a second fixing plate 502 by bolts, and the second fixing plate 502 is connected to the supporting plane by bolts. The second fixing plate 502 can fix the bottom of the counterweight guide rail 4 to improve the stability of the counterweight guide rail 4.

[0043] Embodiment 3 further optimizes the steel belt passenger elevator provided in Embodiment 1 or 2. Specifically, Figure 2 As shown, a car body 6, a traction system 7 and a counterweight frame body 8 are arranged in the hoistway frame 1. The car body 6 is connected between two car guide rails 2, the counterweight frame body 8 is connected between two counterweight guide rails 4, and steel belts are connected between the car guide rails 2, the traction system 7 and the counterweight frame body 8.

[0044] Further, such as Figure 2 As shown, a buffer 9 is provided under the car body 6. The buffer 9 is used for buffering the car body 6 to make the car body 6 stop more smoothly. In extreme cases, the uncontrolled fall of the elevator is extremely dangerous. The buffer 9 can convert the huge kinetic energy of the falling car body 6 into the internal energy of the buffer 9 through its own deformation and energy absorption characteristics, thereby reducing the impact force of the car body 6 and protecting passengers and equipment.

[0045] Further, such as Figure 1 As shown, a guard plate 103 is installed between the vertical beam 102 and the horizontal beam 101 .
