Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a tilt limiting device for an elevator main engine. Background Art

[0002] The elevator main engine, also known as the elevator traction machine, is the power equipment of the elevator. Its function is to transport and transmit power to make the elevator run. In order to ensure the stable use of the elevator main engine, current elevators are usually equipped with devices to prevent the traction machine from tipping over.

[0003] For example, the patent number 202322294105.X previously disclosed by the applicant is a structure for preventing the main engine from tilting on an elevator, which includes a traction base, a traction base, an anti-tilt device, and a plurality of shock absorbing devices located between the traction base and the traction base. The anti-tilt device includes an anti-tilt base, an anti-tilt arm, and a matching bracket. The anti-tilt base is adjustable on the traction base. The matching bracket is connected to the traction base or / and the shock absorbing device. The matching bracket is provided with an anti-tilt matching hole. The lower end of the anti-tilt arm passes through the anti-tilt matching hole and is connected to the anti-tilt base. The upper end of the anti-tilt arm is provided with an anti-tilt limit head located above the matching bracket. When the traction main engine wants to tilt, the matching bracket follows the traction base to move against the anti-tilt arm, so that the matching bracket is limited by the anti-tilt arm, and the linkage traction base and the traction main engine on the traction base are also limited, thereby realizing the anti-tilt function.

[0004] However, during use, it was found that this technical solution still has certain shortcomings. For example, an anti-tilt base needs to be set up, and the bracket and anti-tilt arm need to cooperate to realize the anti-dump function. As a result, more structural components are required for the anti-tilt arm to realize the anti-dump function, which increases the assembly process and parts production costs, and is not conducive to the control of elevator production costs.
