Description

Technical Field

[0001] This utility model relates to the field of elevator base frames, and in particular to a bottom support base frame for construction elevators. Background Technology

[0002] The hoist base frame is the core foundation component of a construction hoist, playing a crucial role in supporting the guide rail frame, transmitting loads, and ensuring equipment stability. The design must take into account structural strength, installation accuracy, and safety protection to ensure the normal operation of the hoist.

[0003] Chinese utility model patent CN202321316365.6 discloses a construction hoist base frame, including a base frame body. The base frame body includes a square-shaped base plate. A hollow cylindrical, split-type limiting plate is provided on the outer side of the base plate. H-shaped longitudinal supports are provided at both ends of the base plate. Concave transverse supports are provided on the outer sides of the two longitudinal supports. A positioning and clamping device is provided at the lower end of the base plate. The positioning and clamping device includes a frustum with a keyway groove inside. A movable block is provided within the keyway groove. A right-angle bracket is provided at the upper end of the movable block. A screw penetrating one side of the frustum is provided at one end of the movable block. This utility model enables modular installation of equipment components, facilitating installation and adjustment. It can be pre-positioned for equipment of different specifications and sizes, ensuring accurate installation and setting, improving stability, and meeting usage requirements.

[0004] However, when the aforementioned construction hoist base frame is in use, the bottom of the guide rail frame is limited by the limiting plate to keep the guide rail frame upright. However, the limiting plate structure can only limit a small part of the bottom of the guide rail frame. When the guide rail frame is large and heavy, there is a risk that the bottom of the guide rail frame may break free from the control of the limiting plate. Utility Model Content

[0018] By adopting the above technical solution, the use of the main body of the base frame is facilitated.

[0019] By employing the above technical solution, the bottom support frame for a construction hoist of this utility model has at least the following beneficial effects:

[0020] Compared with existing technologies, this construction hoist uses a bottom support frame. Through the fixing column, the bottom of the guide rail frame can be accurately installed on the main body of the frame. Through the mounting bracket, the protrusions at the bottom of the guide rail frame can be connected to the main body of the frame, increasing the stability of the guide rail frame and thus improving the structural connection strength between the guide rail frame and the main body of the frame.
