Embodiment Construction

[0018] see Figure 1-4 , an elevator emergency braking leveling device, it includes a base 8, a plurality of chutes 9 are symmetrically arranged on the base, each chute is provided with a blocking post 2, one end of the blocking post is provided with a connecting rod push-pull mechanism 5, connected The rod push-pull mechanism is connected with a return spring 7 and a pull rope 4, and the pull rope is connected with the speed limiter pull rod on the elevator.

[0019] Preferably, in the chute, a push-pull spring 3 is provided between the blocking post and the push-pull mechanism of the connecting rod. The base is provided with a fixed pulley 1, and the pull rope is passed through the fixed pulley. The base is provided with a limit stop 6, and the limit stop is used to limit the push-pull mechanism of the connecting rod, thereby limiting the retracting distance of the stop column. The head of the blocking post is arc-shaped or wedge-shaped. The chutes are provided with 4, wh...

Abstract

A leveling device for emergency braking of an elevator comprises a base. A plurality of sliding grooves are symmetrically arranged on the base, a blocking column is arranged in each sliding groove, one end of each blocking column is connected with a connection rod push-pull mechanism connected with a resetting spring and a pull rope, and the pull rope is connected with a speed limit device pull rod on the elevator. By means of the leveling device, the elevator can just stop at the position of a floor door when a safety gear is used for braking, passengers can leave the elevator quickly and safely, and life and property safety of the passengers can be guaranteed to the largest extent.

Description

technical field [0001] The invention relates to an elevator emergency braking and leveling device. Background technique [0002] In order to successfully rescue the passengers in the elevator when the elevator is in danger, there are already some molded products on the market. However, in those products, the braking of the safety gear is generally used, which ultimately stops the car on the track, and then rescues the passengers. In this case, the car may stay at any position on the track, which will leave a great safety hazard to the subsequent rescue and the personal safety of the passengers. For example, when using the safety gear to brake, the car is stopped in the middle of the floor and the passengers are already panicked. If the car door is opened at this time, they will rush out without hesitation. If you run away, you are likely to fall to the nearest floor, or even fall directly to the bottom of the hoistway from the gap between the floor door and the car door an...
