Description
Technical Field
[0001] The utility model relates to the technical field of elevator equipment, and in particular to a main load-bearing steel beam of an elevator. Background Art
[0002] The elevator traction machine is the power equipment of the elevator, also known as the elevator host. Its function is to transport and transfer power to make the elevator run. It consists of a motor, brake, coupling, reduction box, traction wheel, frame and guide wheel and auxiliary handwheel. The traction machine is fixed to the bottom plate or foundation on the side of the elevator shaft through a support beam or bracket structure.
[0003] Generally, an elevator traction machine has a main load-bearing beam structure, which is used to provide stable support for the elevator drive and its related structures and to provide installation and bearing space for related matching parts. The current mainstream design of the elevator main load-bearing beam is to use one or more I-beams combined with each other. However, the main load-bearing steel beams formed by I-beams currently have insufficient strength, so multiple beams are often required to be combined with each other. This design not only increases the redundant structure of the bracket, but also increases the difficulty of the installation and combination process, thereby increasing the equipment cost.
[0004] In summary, the existing elevator main load-bearing beam has the technical problem of insufficient strength. Utility Model Content

The improved beam is much better than the traditional I-beam design in strength, reduces the amount of main load-bearing beams of the elevator and reduces the assembly process, effectively solving the technical problem of insufficient strength of the existing main load-bearing beams of the elevator.

A preferred rib reinforcement structure design is provided, which forms a wavy plate structure with the rib, greatly improving the compressive performance of the beam.
[0010] As a preferred solution, the rib reinforcement structure includes a trapezoidal concave and convex structure spaced apart from the rib, and the rib reinforcement structure and the rib form a trapezoidal bent plate structure. Another preferred design is provided in parallel, using a trapezoidal bent plate different from the above-mentioned wavy rib structure.

Another rib design parallel to the above two designs is provided, and the rib reinforcement structure and the rib together form a parallel double rib structure.
[0012] As a preferred solution, the ribs and rib reinforcement structures are both provided with mutually parallel protruding reinforcement edges, and the length direction of each reinforcement edge is perpendicular to the length direction of the main load-bearing steel beam of the elevator. Further optimization is carried out on the basis of the above design structure, and further structural improvements are made to the double rib design to enhance the strength of the beam body.
[0013] As a preferred solution, both sides of the rib plate and the rib plate reinforcement structure are provided with flange structures, which are fixedly connected to the top plate by the flange structures. The fixed connection design between the rib plate and the rib plate reinforcement structure and the top plate is optimized, and the flange structures are used to increase the butt joint surface between the rib plate and the top plate and avoid stress concentration at the connection position.
[0014] As a preferred solution, the top plate reinforcement structure includes two linear reinforcement grooves arranged parallel to each other, and the two linear reinforcement grooves are symmetrically distributed on both sides of the center axis of the top plate.
