[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] like Figure 1 As shown, in a specific embodiment of an elevator car frame provided by this utility model, the car frame includes an upper beam assembly 1 and a lower beam assembly 2, such as... Figure 2 As shown, the upper beam assembly 1 includes a guardrail 101, an upper beam plate 102, and an upper guide shoe 103. The guardrail 101 is used to improve the stability of the connection between the car body and the car frame, such as... Figure 4 As shown, the lower beam assembly 2 includes a lower beam plate 201. Support plates 204 are respectively provided at both ends of the top surface of the lower beam plate 201 along its length. Support beam plates 202 are respectively provided on the corresponding sides of the lower beam plate 201. The support beam plates 202 are located at the bottom of the two support plates 204. A secondary beam plate 203 is also provided between one of the support beam plates 202 and the lower beam plate 201, located between the two support plates 204. The support plates 204 connect the lower beam plate 201 and the support beam plates 202 arranged in a three-dimensional pattern to form a stable base plate. By providing a secondary beam plate 203 between one of the support beam plates 202 and the lower beam plate 201, the stability of the base plate is improved, thereby enhancing the stability of the entire car frame and providing a higher guarantee for the safe use of the elevator.

[0027] There are two upper guide shoes 103, which are respectively set on the top of the upper beam plate 102 on both sides. Lower guide shoes 207 are respectively set on the bottom of the lower beam plate 201 on both sides. The upper guide shoes 103 and the lower guide shoes 207 are located on the same vertical line to ensure verticality. A support plate 4 is set on the lower guide shoe 207. The upper guide shoe 103 and the lower guide shoe 207 on the same side are connected by the same support plate 4 through bolts, thus initially forming a frame.

[0028] Both the lower beam plate 201 and the upper beam plate 102 are U-shaped. The grooves of the upper beam plate 102 and the lower beam plate 201 face each other. Vertical beam plates 3 are bolted to both sides between the grooves of the upper beam plate 102 and the lower beam plate 201. The corresponding two side walls of the vertical beam plate 3 are simultaneously attached to the two side walls of the groove of the upper beam plate 102 or the lower beam plate 201, limiting the vertical beam plate 3 so that when the vertical beam plate 3 is located in one of the grooves, it cannot move in a certain direction. This improves stability and facilitates the installation work.

[0029] The upright beam 3 is designed as a U-shaped plate, with the openings of the two upright beam 3 facing away from each other. The support plate 4 is designed as a T-shaped plate, with the horizontal part of the support plate 4 located at the opening of the upright beam 3 and the vertical part of the support plate 4 located inside the upright beam 3. The upright beam 3 and the support plate 4 work together to support the upper beam assembly 1, improving stability while making reasonable use of space through their special shapes. The upper and lower ends of the support plate 4 extend from the upright beam 3, and the extended parts of the upright beam 3 and the support plate 4 connect to different positions of the lower beam assembly 2 and the upper beam assembly 1, allowing both the upright beam 3 and the support plate 4 to perform their respective load-bearing functions. Multiple adhesive points 6 are provided on the upright beam 3. The car is composed of a car frame and a car body. The adhesive points 6 are used to connect the car frame and the car body, further improving the stability of the car structure. The upright beam 3 is also equipped with a bumper assembly 5 to ensure passenger safety. Figure 3 As shown, the impact bow assembly 5 includes an impact bow bracket 502 mounted on the upright beam plate 3, and an impact bow body 501 mounted on the impact bow bracket 502. The impact bow assembly 5 ensures that even in the worst-case scenario, the elevator will not run out of control and derail, thus maximizing elevator safety.

[0030] Two positioning plates are respectively provided on the top of both sides of the lower beam plate 201. The positioning plates are used to quickly position the support plate 204 by abutting against the positioning plates, which is convenient for installation. On the other hand, the two positioning plates prevent the support plate 204 from rotating when it is installed with bolts, thus achieving a limiting function. The upper beam plate 102 has slots on both sides, and the support plate 4 extends out of the slots. The support plate 4 is clamped through the slots for further limiting.

[0031] like Figure 4As shown, the lower beam plate 201 is provided with lug plates 205 connected to the upright beam plate 3 by bolts on both sides. There are two lug plates 205 on the same side, and a fixing plate 206 is provided between the two lug plates 205 on the same side. The fixing plate 206 is located at the bottom of the upright beam plate 3 to support the upright beam plate 3. A support plate 209 is provided on the side of the lug plate 205 near the sub-beam plate 203 facing the sub-beam plate 203. A wheel axle 210 is provided on the support plate 209. The wheel axle 210 is connected to the sub-beam plate 203 by bolts. A reverse rope wheel 208 is provided on the wheel axle 210 between the support plate 209 and the sub-beam plate 203. The sub-beam plate 203 is a U-shaped plate, and the opening of the sub-beam plate 203 faces the bracket beam plate 202.

[0032] During installation, use a hoist to lift the lower beam assembly 2 and use a spirit level to ensure that its levelness is no greater than 0.5 / 1000. Before installing the upright beam plate 3, first lift the upper beam assembly 1, then connect the two upright beam plates 3 to the lower beam assembly 2, and use a magnetic plumb line to ensure that the vertical deviation of the upright beam plate 3 over the entire height is no greater than 2.0mm. After the upright beam plate 3 is installed, slowly lower the upper beam assembly 1 and connect it to the upright beam plate 3, use a spirit level to level it, and ensure that the levelness of the upper beam assembly 1 is no greater than 0.5 / 1000. Use a plumb line to check whether the upper guide shoe 103 and the lower guide shoe 207 are on the same vertical line.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
