Description

Technical Field

[0001] This utility model relates to a plug-in elevator car and belongs to the field of elevator technology. Background Technology

[0002] Materials such as sintered stone slabs and floor tiles are characterized by high hardness, strong machinability, lightness, and durability, and are currently widely used in the industry to replace the original solution of laying marble on the car floor. The thickness of the materials is often thinner than marble, which can reduce the overall height of the car floor components and further reduce the required depth of the shaft pit. Due to the thinness of the car floor and the small thickness of the aluminum alloy frame car wall, such as sheet metal bent car floor frame, there are problems of low strength and high bending accuracy. If the solution is to use thick plates to raise the car floor, there are disadvantages such as low material utilization and heavy weight. Both of the above solutions have problems with poor processability and inconvenient installation. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] As attached Figure 1-5As shown, the plug-in elevator car of this utility model includes a car bottom frame 1, a car bottom edge frame 2, a car enclosure 3, and a car floor 4.

[0024] In this embodiment, the car bottom frame 1 can be made of high-strength steel to form a rectangular frame system, which serves as a supporting foundation for the subsequent installation of components.

[0025] As attached Figure 2 and 4 As shown, the upper and lower ends of the car bottom frame 2 are respectively provided with a first sliding groove 21 and a second sliding groove 22. The cross-section of the second sliding groove 22 is T-shaped. A T-bolt kit 23 is provided in the second sliding groove 22. The T-bolt kit 23 is used to fix the car bottom frame 2 to the car bottom frame 1. The T-bolt kit 23 is a commonly used component in the field, which includes a T-bolt and a matching nut.

[0026] During installation, the head of the T-bolt is inserted into the second groove 22, allowing the T-bolt to slide freely within the second groove 22. After adjusting the position of the car bottom frame 2 on the car bottom frame 1, the T-bolt is tightened by tightening the nut under the car bottom frame 1, thereby firmly fixing the car bottom frame 2 to the car bottom frame 1. This connection method is not only convenient to install, but also facilitates subsequent adjustments and maintenance.

[0027] In this embodiment, the bottom frame 2 is made of aluminum alloy profile. Aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, which can effectively reduce the overall weight of the car and extend its service life.

[0028] The car wall 3 is made of aluminum alloy profile. The bottom end of the car wall 3 is provided with an installation groove 31. The cross-section of the installation groove 31 is T-shaped. A wall panel fastener 32 with the same cross-sectional shape is provided in the installation groove 31. The lower end of the wall panel fastener 32 is embedded in the first sliding groove 21 of the car bottom frame 2. A locking bolt 33 is provided on the wall panel fastener 32. The locking bolt 33 passes through the car bottom frame 2 and is fixed to the car bottom frame 1. It can be understood that a through hole (not shown) needs to be pre-drilled on the car bottom frame 2 for the locking bolt 33 to pass through.

[0029] During installation, the locking bolt 33 passes through the car bottom frame 1 and the car bottom side frame 2 from bottom to top, and is threadedly connected to the wall panel fastener 32. By tightening the locking bolt 33, the wall panel fastener 32, the car bottom side frame 2 and the car bottom frame 1 are tightly connected together.

[0030] Furthermore, a set screw 34 is provided in the mounting groove 31. The lower end of the set screw 34 abuts against the wall panel fastener 32, and the upper end of the set screw 34 abuts against the top wall of the mounting groove 31 to position the wall panel fastener 32 and prevent it from moving left and right.

[0031] The car floor 4 is fixed to the upper surface of the car bottom frame 1, and the height of the car floor 4 is not higher than the height of the car bottom frame 2. A cement filling plate 5 is provided between the car floor 4 and the car bottom frame 1. The cement filling plate 5 has good load-bearing capacity and stability, and can evenly distribute the load on the car floor 4, so as to avoid the car bottom frame 1 from being deformed due to excessive local stress.

[0032] To enhance the connection strength and sealing between the components, structural adhesive 6 is provided between the cement filling plate 5 and the car bottom frame 1, between the car floor 4 and the cement filling plate 5, and between the ends of the car floor 4 and the cement filling plate 5 and the car bottom frame 2. The use of structural adhesive 6 can effectively fill the tiny gaps between the components and improve the seismic performance and waterproof performance of the overall structure.

[0033] Furthermore, the width of the car wall 3 is greater than the width of the car bottom frame 2, and the outer side of the car wall 3 is aligned with the outer side of the car bottom frame 2. The inner side of the car wall 3 extends towards the car floor 4, and the extended side of the car wall 3 covers the car bottom frame 2. This design not only makes the appearance of the car cleaner and more beautiful, but also effectively prevents dust, debris and other things from entering the gap between the car bottom frame 2 and the car wall 3, reducing maintenance costs.

[0034] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
