Problems solved by technology

The buffer spring device at the bottom of the hoistway can reduce the impact of the elevator hitting the ground when it falls, but the effect is limited
On the one hand, due to the frequent overloading of the elevator; on the other hand, when the elevator is installed and maintained, the installation and adju

Example Embodiment

[0017] The present invention will be further described in detail below through specific implementations:

[0018] The reference signs in the drawings of the specification include: baffle 10, car 20, support plate 21, electromagnet 31, compression spring 32, partition 33, hinge rod 34, and limit block 35.

[0019] Such as figure 1 As shown, the car 20 is divided into upper and lower layers by the support plate 21. The elevator fall braking device includes a rack-shaped baffle plate 10 fixed on both side walls of the hoistway and a braking unit arranged in the lower layer of the car 20. The brake unit includes an electromagnet 31, an iron partition 33, a hinge rod 34, a compression spring 32, and a limit block 35. The limit block is welded to the bottom of the car 20, and the upper end of the compression spring is installed on the electromagnet 31 , The lower end is connected to the partition 33. Such as figure 2 As shown, the partition 33 is sprayed with anti-rust paint, and is pro

Abstract

The invention belongs to a braking device or a catch pawl device acting between a lift car or a cage or a skip and a fixed guiding element or a winding channel or the inner surface of a shaftway and particularly discloses an elevator falling braking device. The elevator falling braking device comprises a rack-shaped baffle fixed to the side wall of a shaftway and a braking unit arranged in the lower layer of the lift car. The braking unit comprises an electromagnet, a partition plate made from iron, a hinging rod, an elastic piece and a limiting block; the limiting block is fixed to the bottom of the lift car; one end of the elastic piece is connected to the electromagnet, and the other end of the elastic piece is connected to the partition plate; a groove is formed in the partition plate; the hinging rod is hinged to the interior of the groove; and the hinging rod can be clamped on the baffle. Under the normal condition, the electromagnet is in the power-off state. When an elevator falls, the electromagnet is powered on, generates magnetic force, overcomes elasticity of the elastic piece and moves to the partition plate. When the electromagnetic magnet makes contact with the hinging rod, the hinging rod is driven to rotate, and therefore the hinging rod is clamped on the baffle.
