[0002] Elevators are equipment used to transport people or goods vertically, and are commonly found in high-rise buildings, shopping malls, hospitals, factories and other places. Elevators are driven by electric motors or hydraulic systems and move up and down along vertical tracks. They usually have doors and can stop at different floors, and passengers can select the desired floor by pressing buttons. The design and installation of elevators need to strictly comply with relevant safety standards to ensure the safety of passengers.

[0003] Currently, the existing elevators need the auxiliary support of the main frame. However, during the use of the existing elevator main frame, its reel simply adopts a single set of reel for reeling. During its use, the support strength of the single set of steel cable reeling is low, which makes the overall lifting load-bearing capacity of the equipment limited and reduces the utilization efficiency. Therefore, the existing main frame needs to be improved. Utility Model Content

[0004] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a main frame of an elevator to solve the problem that the existing main frame can only reel in a single set of steel cables and has poor overall strength and low utilization rate.

[0007] As a preferred technical solution, the top of the base frame is located at both sides of the front end of the support frame and mounting brackets are fixedly installed, and the inner side of the upper end of the mounting bracket is rotatably connected to a guide shaft.

[0008] As a preferred technical solution, a shielding ceiling is fixedly installed on the top of the support frame, and the shielding ceiling is inclined toward the front end.

[0009] As a preferred technical solution, a fixing hole is opened at the upper end of the fixing piece, and the fixing hole passes through the fixing piece.

[0010] As a preferred technical solution, a transmission pulley is fixedly mounted on the front side of the transmission wheel, and the cross-section of the transmission pulley is in an I-shape.

[0011] As a preferred technical solution, mounting holes are provided at equal intervals on one end of the top of the host mounting plate, and the bottoms of the mounting holes penetrate the host mounting plate.

[0012] To sum up, the utility model mainly has the following beneficial effects: by arranging transmission wheels at equal intervals on the outer surface of the rotating shaft, during the use of the equipment, multiple sets of steel cables can be synchronously reeled up through the transmission wheels, and the lifting goods of the elevator can be assisted by the multiple sets of steel cables. Through the coordination of the multiple sets of steel cables, the overall stability of the main frame can be improved, the number of steel ropes can be effectively increased, and the utilization rate can be improved. The main frame has a simple structure and a low overall use cost. At the same time, the whole is composed of a steel structure frame, and the whole has strong stability.
