Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and particularly relates to a 12:1 machine room layout structure applied to an extra-large load freight elevator. Background Art

[0002] With the progress of society and the development of economy, the market demand for large load freight elevators is increasing continuously.

[0003] In order to improve the load capacity of the freight elevator, at present, most of them adopt the method of increasing the traction ratio of the freight elevator. For example, the structure of the extra-large load freight elevator disclosed in the technical solution of CN202023140294.8 includes a freight elevator frame composed of four groups of side-by-side carriages and four groups of side-by-side counterweight devices. First load-bearing beams are arranged on both sides above the freight elevator frame. A second load-bearing beam is arranged on one side surface of one of the first load-bearing beams. Four side-by-side guide wheels are arranged on both the first load-bearing beam and the second load-bearing beam. A traction machine is arranged between the first load-bearing beam and the second load-bearing beam. A counterweight wheel is arranged on the counterweight device. Carriage bottom wheels are arranged on both sides of the bottom of the carriage. The traction machine, the carriage bottom wheels, the guide wheels and the counterweight wheels are sequentially connected by traction ropes to form an 8:1 traction ratio connection structure, so as to realize the handling of heavier goods. However, this solution still has the problem that the traction ratio is insufficient to meet the handling requirements of heavier goods, and in the case of eccentric load, due to the lack of effective connection and positioning between the first load-bearing beam and the second load-bearing beam, the first load-bearing beam and the second load-bearing beam have the risk of overturning, affecting the safety and stability of the operation of the freight elevator.
