Description

Technical Field

[0001] This utility model relates to the field of mobile elevator technology, and specifically to a mobile frame structure applied to mobile elevators. Background Technology

[0002] With the acceleration of urbanization and the increasing demand for temporary and mobile buildings, mobile cabins, as a new type of building, have been widely used in various fields. However, traditional elevator shaft installation structures are often designed for fixed buildings and cannot meet the special requirements of mobile cabins in terms of structural stability, ease of installation, and adjustability.

[0003] In traditional technologies, elevator shaft installation typically involves a complex construction process and a significant amount of on-site work. For example, traditional shaft installation requires the pre-construction of scaffolding inside or outside the building, followed by the assembly and securing of the shaft. This method is not only time-consuming and labor-intensive but also difficult to implement in temporary structures such as mobile cabins, where the structure and location may need to be adjusted to meet changing usage requirements.

[0004] Therefore, in existing elevator shaft structures, there are shaft structures that achieve overall installation by splicing together multiple shaft frames. This allows for design based on the height of the mobile cabin, thereby improving flexibility and adjustability, adapting to various changes, increasing installation efficiency, and reducing costs. However, while some of these new shaft structures are easy to install, they have shortcomings in structural stability. In particular, it is difficult to keep the car rails or counterweight rails aligned after splicing, or vibrations may occur at the connection points, making it difficult to ensure the safety and stability of the elevator during operation (see the splicing method of guide rails in a mobile villa elevator showroom disclosed in Chinese Utility Model Patent Application No. 202323026788.7). Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a mobile frame structure for use in mobile elevators.

[0027] like Figures 1 to 6As shown, this embodiment discloses a mobile frame structure for a mobile elevator, including a mobile cabin 1, and an upper hoist 2 and a lower hoist 3 installed in the mobile cabin 1, which are connected by steel plates to form a frame structure. The bottom of the upper hoist 2 is detachably installed on the top of the lower hoist 3. The upper hoist 2 includes two symmetrically arranged upper car guide rails 21 and two symmetrically arranged upper counterweight guide rails 22. The two upper car guide rails 21 are respectively installed on the left and right sides inside the upper hoist 2, and the two upper counterweight guide rails 22 are installed on the left or right side inside the upper hoist 2. The lower hoist 3 contains... The system includes two symmetrically arranged lower car guide rails 31 and two symmetrically arranged lower counterweight guide rails 32. The two lower car guide rails 31 are respectively installed on the left and right sides inside the lower derrick 3 and aligned with the upper car guide rail 21. The two lower counterweight guide rails 32 are installed on the side inside the lower derrick 3 corresponding to the upper counterweight guide rail 22. When the upper derrick 2 and the lower derrick 3 are spliced, the upper car guide rail 21 and the lower car guide rail 31 are connected to form a car guide rail, and the upper counterweight guide rail 22 and the lower counterweight guide rail 32 are connected to form a counterweight guide rail. The upper car guide rail 21 and the lower car guide rail 32 are connected to form a counterweight guide rail. Guide rail fastening devices 4 are provided at the connection points of the car guide rail 31 and the connection points of the upper counterweight guide rail 22 and the lower counterweight guide rail 32. Specifically, the upper car guide rail 21, the lower car guide rail 31, the upper counterweight guide rail 22, and the lower counterweight guide rail 32 are all T-shaped guide rails. The guide rail fastening device 4 is clamped at the short side of the T-shaped guide rail, and the long side of the T-shaped guide rail is used for guidance. The guide rail fastening device 4 includes a fastening seat 41 and two clamping blocks 42 movably mounted on the fastening seat 41. The two clamping blocks 42 are arranged opposite each other, and the inner sides of the two clamping blocks 42 form a clamping mechanism for clamping the upper and lower guide rails. The clamping port 40, the guide rail fastening device 4 further includes a first adjusting rod 43 for driving the two clamping blocks 42 to move closer to each other, and a second adjusting rod 44 for driving the two clamping blocks 42 to tighten towards the fastening seat 41. When the clamping blocks 42 move closer to each other, they clamp the guide rail in the left-right direction. When the clamping blocks 42 tighten, they press the guide rail in the front-back direction. The first adjusting rod 43 is threaded onto the fastening seat 41 to push the clamping blocks 42 to move. The second adjusting rod 44 is rotatably engaged with the fastening seat 41 and threadedly engaged with the clamping blocks 42. When the second adjusting rod 44 rotates, it drives the clamping blocks 42 to tighten.

[0028] In this embodiment, after the upper derrick 2 and the lower derrick 3 are spliced ​​together, a car is slidably connected between the two car guide rails, and a counterweight is slidably connected between the two counterweight guide rails. An installation frame is also provided on the upper part of the upper derrick 2 near the upper section of the counterweight guide rail 22, and a traction machine is installed on the installation frame.

[0029] In this embodiment, the upper derrick 2 and the lower derrick 3 have basically the same structure, both including four vertically arranged support angle steels 231 and multiple horizontally arranged support side plates 232. The multiple support side plates 232 are connected between two adjacent support angle steels 231 to form a three-sided enclosed structure. Specifically, the multiple support side plates 232 are respectively connected to two support angle steels 231 located on the left, right and rear sides. At the same time, a rectangular top frame is formed by connecting beams 233 at the top of the upper derrick 2, and a rectangular bottom frame is formed by connecting beams 233 at the bottom of the lower derrick 3. A connecting block 235 is provided at the bottom of the four support angle steels 231 on the upper derrick 2, and a support block 236 is provided at the top of the four support angle steels 231 on the lower derrick 3. The upper derrick 2 is positioned and fixed on the support block 236 by the connecting block 235 to form support.

[0030] Furthermore, to improve the stability of the guide rails, connecting plates 234 are provided on the inner side of the left and right support side plates 232 in the upper derrick 2 and the lower derrick 3. The upper car guide rail 21 and the upper counterweight guide rail 22 are fixedly connected to the support side plates 232 on the upper derrick 2 through the connecting plates 234. The lower car guide rail 31 and the lower counterweight guide rail 32 are fixedly connected to the support side plates 232 on the lower derrick 3 through the connecting plates 234. It should be noted that in the upper derrick 2 and the lower derrick 3, the upper and lower sides of the support side plates 232 located in the middle are respectively provided with connecting plates 234. However, the support side plate 232 near the bottom of the upper derrick 2 is only provided with a connecting plate 234 on its upper side, and the support side plate 232 near the top of the lower derrick 3 is only provided with a connecting plate 234 on its lower side.

[0031] In this embodiment, in order to further improve the structural strength of the upper derrick 2 and the lower derrick 3, multiple reinforcing rods 237 are provided on both sides of the upper derrick 2 and the lower derrick 3. The multiple reinforcing rods 237 are inclinedly connected between two supporting angle steels 231. The reinforcing rods 237 and the supporting side plate 232 form multiple triangular structures between the two supporting angle steels 231, thereby improving the bending resistance.

[0032] In this embodiment, when the mobile cabin 1 has multiple layers, the height requirement of the mobile cabin 1 may not be met by splicing the upper derrick 2 and the lower derrick 3. Therefore, several middle derricks 5 are provided between the upper derrick 2 and the lower derrick 3. The structure of the middle derricks 5 is basically the same as that of the upper derrick 2 and the lower derrick 3. They are all connected by supporting angle steel 231, supporting side plates 232 and connecting rods to form a three-sided enclosed frame structure. The difference is that the middle derricks 5 do not have a top frame at the top and a bottom frame at the bottom. The middle derricks 5 have supporting blocks 236 at the top of the supporting angle steel 231 and connecting blocks 235 at the bottom of the supporting angle steel 231. Multiple middle derricks 5 can be spliced ​​sequentially between the upper derrick 2 and the middle derricks 5 to meet the height requirement of the mobile cabin 1.

[0033] Furthermore, the inner side of the middle derrick 5 is also provided with two opposing middle car guide rails 51 and two opposing middle counterweight guide rails 52. The structure of the middle car guide rails 51 and the middle counterweight guide rails 52 is the same as that of the car guide rails and the counterweight guide rails, and the installation method and relative position are also the same. After multiple middle derricks 5 are spliced ​​together, the upper car guide rail 21 and the lower car guide rail 31 are connected by the middle car guide rails 51, and the upper counterweight guide rail 22 and the lower counterweight guide rail 32 are connected by the middle counterweight guide rails 52. Similarly, guide rail fastening devices 4 are provided at the connection points of the middle car guide rails 51 with the upper car guide rails 21 and the lower car guide rails 31, and guide rail fastening devices 4 are provided at the connection points of the middle counterweight guide rails 52 with the upper counterweight guide rails 22 and the lower counterweight guide rails 32.
