Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] As described in the background section, traditional elevator car frame designs often employ a fixed upright and base frame structure. This design results in a large overall size after manufacturing, causing significant transportation difficulties, especially in narrow or inaccessible construction sites. The transportation of large elevator car frames often becomes a key factor restricting project progress and cost.

[0034] To solve this technical problem, this utility model provides an elevator car frame.

[0035] For details, please refer to Figures 1-4 The elevator car frame specifically includes:

[0036] The upright assembly 1 has a bottom frame assembly 4 rotatably connected to its inner side. A second bottom beam 2 located at the bottom of the bottom frame assembly 4 is bolted to the bottom of one side of the upright assembly 1. The second bottom beam 2 is bolted to the bottom frame assembly 4.

[0037] The elevator car frame provided by this utility model, through the upright frame assembly 1 and the bottom frame assembly 4 set together, allows the bottom frame assembly 4 to rotate to a position parallel to the upright frame assembly 1 during transportation, thereby greatly reducing the overall volume and space occupied, making it easier for the elevator car frame to pass through narrow passages or restricted spaces, and reducing transportation difficulty and cost.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] Example 1, please refer to Figures 1-4 An elevator car frame includes a vertical frame assembly 1, a bottom frame assembly 4 rotatably connected to the inner side of the vertical frame assembly 1, and a second bottom beam 2 located at the bottom of the bottom frame assembly 4 is bolted to the bottom of one side of the vertical frame assembly 1. The second bottom beam 2 is bolted to the bottom frame assembly 4. By setting the vertical frame assembly 1 and the bottom frame assembly 4 together, this application allows the bottom frame assembly 4 to rotate to a position parallel to the vertical frame assembly 1 during transportation, thereby significantly reducing the overall volume and space occupied. This makes it easier for the elevator car frame to pass through narrow passages or restricted spaces, reducing transportation difficulty and cost.

[0042] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the bottom frame assembly 4 includes a bottom frame body 401, which is disposed inside the upright assembly 1. The bottom frame body 401 is used to connect with the bottom of the car, and a number of mounting holes are provided on the bottom frame body 401. The upright beam 101 is used to connect with the side of the car.

[0043] Example 2 further optimizes the elevator car frame provided in Example 1. Specifically, a connector is provided between the bottom frame body 401 and the upright assembly 1. The connector is used to realize the connection between the upright assembly 1 and the bottom frame body 401.

[0044] Furthermore, such as Figure 1 As shown, the connector includes two slide grooves 3 on the upright assembly 1. A connecting shaft 402 is inserted into each of the two slide grooves 3. The two connecting shafts 402 are fixedly installed on both sides of the bottom frame body 401. The arrangement of the connecting shafts 402 and the slide grooves 3 allows the bottom frame body 401 to rotate and move up and down.

[0045] Furthermore, such as Figure 1 As shown, the support frame assembly 1 includes two upright beams 101, and a first bottom beam 103 is fixedly connected between the two upright beams 101. The top of the first bottom beam 103 contacts the bottom of the bottom frame body 401. The first bottom beam 103 can reinforce the upright beams 101 and support the bottom frame body 401. The first bottom beam 103 can play a supporting role for the bottom frame body 401.

[0046] Furthermore, such as Figure 1 As shown, the second bottom beam 2 is bolted between the two vertical beams 101. The second bottom beam 2 and the first bottom beam 103 are located on both sides of the vertical beam 101. The second bottom beam 2 can be removed after unscrewing the bolts connecting the second bottom beam 2 and the vertical beam 101.

[0047] Furthermore, such as Figure 1 As shown, the two chutes 3 are respectively opened on the two vertical beams 101.

[0048] Example 3 further optimizes the elevator car frame provided in Example 1 or 2, specifically, as follows: Figures 1-2 As shown, a stop block 6 is fixedly connected between the two upright beams 101 on their sides that are close to each other. The stop block 6 is located below the bottom frame body 401. The stop block 6 can support and limit the bottom frame body 401 after it is rotated to be parallel with the upright beams 101.

[0049] Furthermore, such as Figures 1-2 As shown, two horizontal beams 102 are connected between the two vertical beams 101, and the horizontal beams 102 are located at the top of the vertical beams 101.

[0050] Furthermore, such as Figures 1-4 As shown, both the upright beam 101 and the base frame 401 are provided with connecting holes 5. The connecting holes 5 are used to install diagonal tie rods to improve the overall stability.

[0051] The elevator car frame provided by this utility model is used as follows:

[0052] During transportation, the form of this application will be changed from Figure 1 Switch to Figure 5 Unscrew the bolts connecting the second bottom beam 2 to the bottom frame body 401 and the upright beam 101, remove the second bottom beam 2, push the bottom frame body 401 upward, and rotate the bottom frame body 401 around the connecting shaft 402 to make the bottom frame body 401 parallel to the upright beam 101. Then, reinstall the second bottom beam 2 onto the upright beam 101 with bolts. At this time, the bottom of the bottom frame body 401 contacts the stop block 6, preventing the bottom frame body 401 from moving downward. The second bottom beam 2 limits the bottom frame body 401, preventing it from rotating further, thus limiting the bottom frame body 401. At this time, the overall volume is reduced, making transportation easier. The integrity of the overall structure is also ensured during transportation, reducing the possibility of parts loss. Furthermore, 4 can be partially protected by 1 during transportation.

[0053] When using this application, the form of this application shall be changed from... Figure 5 Switch to Figure 1Unscrew the bolts connecting the second bottom beam 2 and the upright beam 101, remove the second bottom beam 2, rotate the bottom frame body 401 around the connecting shaft 402 to make the bottom frame body 401 rotate horizontally, push the bottom frame body 401 downward to make the bottom frame body 401 contact the top of the first bottom beam 103, and connect the second bottom beam 2 between the upright beam 101 and the bottom frame body 401 with bolts.
