Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to a shallow pit elevator car bottom structure. Background Art

[0002] With the development of high-rise buildings, elevators, as the main vertical transportation tools, are in increasing demand. However, in building design, the depth of the elevator shaft pit is often restricted by space and structure and cannot meet the installation requirements of conventional elevators. In traditional methods, the depth of the pit is reduced by omitting the car bracket and the car bottom shock pad, but this will lead to a decrease in the running comfort of the elevator and an increase in installation costs. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a shallow pit elevator car bottom structure, aiming to reduce the demand for the depth dimension of the shaft pit by the elevator and improve the applicability and installation convenience of the elevator. To achieve the above purpose, the utility model is realized through the following technical solutions:

[0004] A shallow pit elevator car bottom structure includes a car bottom (1), a car bottom panel (101), a car bottom side frame (102), a side frame reinforcing rib (103), a car bottom cross beam (104), a bracket (2), a bracket side frame (201), a bracket front and rear frame welded part (202), and a shock pad (3). It is characterized in that: the design of the car bottom side frame (102) and the side frame reinforcing rib (103) can not only ensure the strength and stiffness of the car bottom, but also effectively reduce the vibration transmitted from the car wall to the car bottom panel (101). The car bottom (1) is assembled and installed through the bracket side frame (201) and the bracket front and rear frame welded part (202). This combination method can not only ensure the strength and stiffness of the overall structure, but also reduce the demand for the depth dimension of the elevator shaft pit.

[0005] The utility model realizes shock prevention and strength improvement in the following ways: the car bottom (1) adopts the design of the side frame (102) and the reinforcing rib (103), ensuring the strength and stiffness of the structure and at the same time reducing the possibility of vibration transmitted to the car bottom panel (101). The side frame (201) and the front and rear frame welded parts (202) of the bracket (2) are assembled and installed, enhancing the stability and firmness of the overall structure. The shock pad (3) further absorbs vibration, improving the smoothness and comfort of the elevator operation. Compared with the prior art, the utility model has the following beneficial effects:

[0006] 1. By optimizing the design of the car bottom side frame and the reinforcing rib, the utility model greatly improves the strength and stiffness of the car bottom, effectively reduces vibration transmission, and enhances the smoothness of the elevator operation.

[0007] 2. By combining the bracket side frames and the front and rear frame weldments, the utility model not only ensures the strength and stiffness of the structure, but also significantly reduces the requirement for the depth of the hoistway pit, reducing the installation difficulty and cost.

[0008] 3. The utility model adopts a shock-absorbing pad design, further enhancing the comfort and stability of the elevator operation, extending the service life of the elevator, and enhancing the user experience.

[0009] Through the above multi-level optimization design, the utility model significantly improves the overall performance of the car bottom structure of the shallow pit elevator, meeting the higher requirements of modern elevators for installation space and running smoothness.

[0016] The following will describe in detail the specific embodiments of the utility model with reference to the accompanying drawings:

[0017] As Figure 1 shown, the car bottom (1) includes a car bottom panel (101), a car bottom side frame (102), side frame stiffening ribs (103) and a car bottom cross beam (104). The side frame stiffening ribs (103) are welded to the car bottom side frame (102), and their quantity and structure are determined according to the size length and cross-sectional shape of the car bottom side frame (102). The car bottom cross beam (104) is welded between the left and right car bottom side frames (102), and its quantity and spacing are determined by the size length of the car bottom side frame (102). Finally, the car bottom panel (101) is firmly welded to the car bottom cross beam (104) and the left and right car bottom side frames (102) to form the car bottom (1).

[0018] As Figure 2As shown in the figure, the bracket (2) is composed of a bracket side frame (201) and a bracket front and rear frame welded part (202). Both ends of the bracket side frame (201) are respectively welded to the same end of two bracket front and rear frame welded parts (202), and another bracket side frame (201) is welded to the other end of the two bracket front and rear frame welded parts (202), and the welding combination forms the bracket (2).

[0019] As Figure 3 and Figure 4 shown, the lower part of the shock absorber pad (3) is connected to the bracket side frame (201) of the bracket (2), and the upper part is connected to the car bottom side frame (102) of the car bottom (1). The number of shock absorber pads (3) is mainly determined by the size of the car bottom (1). The overall structure composed of the car bottom (1), the bracket (2) and the shock absorber pad (3) is the overall structure of the present utility model. Compared with the traditional car bottom structure, the height of the bracket side frame (201) is reduced in the structure of the present utility model.

[0020] As Figure 5 shown, the car bottom side frame (102) and the side frame reinforcing rib (103) not only support the car bottom panel (101) and the car wall, but also separate the car bottom panel (101) from the car wall, improve the stability of the car wall, and reduce the vibration transmitted to the car bottom panel (101). The cross-sectional shape of the car bottom side frame (102) makes its strength and stiffness higher than that of ordinary bent parts or plate parts, and the structure of the side frame reinforcing rib (103) further improves the strength and stiffness of the car bottom side frame (102), reduces the bending height at the place where the car bottom side frame (102) supports the car bottom panel (101), thereby effectively reducing the requirement for the pit depth and ensuring the safety of the overall structure of the car bottom.

[0021] The present utility model provides a shallow pit elevator car bottom structure. Through optimized design, it can not only reduce the requirement of the elevator for the pit depth, but also ensure the strength and stiffness of the elevator car bottom, and improve the operation effect and riding comfort of the elevator.
