Abstract

The invention discloses a brake device of a top rushing prevention elevator, which comprises a first guide rail (2) which is arranged in a lifting channel (1) and enables a cage (3) to be lifted through a guide shoe (4). The first guide rail (2) comprises a first rail (6) and a second rail (7) which are parallel to each other; the brake device also comprises a second guide rail (8); the second guide rail (8) comprises a third rail (11) and a fourth rail (12) which are used for enabling the cage (3) to stop moving, arranged at the top end of the lifting channel (1) and fixedly connected with the first rail (6) and the second rail (7) in an extending way; and the third rail (11) and the fourth rail (12) respectively form included angles with the vertical direction and are arranged in a splayed way. As the brake device is provided with the second guide rail, the braking of the elevator is more secure and reliable.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a braking device and an elevator system for an anti-overrun elevator. Background technique [0002] At present, the car of the elevator is installed in the hoistway, and the car goes up and down along the first track and the second track that are arranged in parallel with the first guide rail that is connected to the car through the guide shoes in the hoistway. If it loses control at the top of the passage, it may rush upwards to the top of the lifting passage, resulting in a phenomenon of "rushing to the top", resulting in equipment damage, and even casualties. [0003] When the existing technology solves the above problems, the following two methods are mainly adopted. One is to use a rope clamp to clamp the wire rope to stop the car when the elevator is overspeed. The other is to use safety gear to brake upward. , use the safety gear to clamp the guide rail...
