Standby braking device for well chamber elevator

Abstract

The invention discloses a standby braking device for a well chamber elevator. The standby braking device comprises an elevator car, a control mechanism arranged in the elevator car and a wall grabber mechanism matched with the control mechanism; the control mechanism comprises a control button arranged on the upper side of a control panel in the elevator car, a rotating shaft arranged on the upper side of the control button and a baffle rotationally matched with the rotating shaft; the wall grabber mechanism comprises vacuum suction cups symmetrically arranged on the two sides of the elevator car and connecting fasteners for connecting the vacuum suction cups and the elevator car. When a braking device of the elevator breaks down, the elevator stops in an unconventional position, the control button in the control mechanism is used for manually controlling the wall grabber mechanism to pop up the suction cups to temporarily fix the elevator, accidents such as top rushing or rapid falling are prevented from occurring when the braking faults are eliminated, the suction cups are recovered after the faults of the braking device are eliminated, the suction cups can be used again, the accident rate is reduced, and the standby braking device is worthy of wide popularization.

Description

technical field [0001] The invention relates to the technical field of elevator braking, in particular to a spare braking device for a shaft elevator. Background technique [0002] The elevator is a means of transportation, and the brake is equivalent to the brake system. When the elevator brake fails, the elevator usually stops at the unconventional position where the brake is lost. At this time, the faulty elevator is somewhat like a car parked on a ramp. It has stopped, but at any time, due to the sliding effect of the car on the slope, the car is prone to slide. Once the slide occurs, it will become faster and faster, rushing down the ramp quickly and uncontrollably , it will not stop until it encounters an obstacle. In order to prevent the car from slipping, you should try not to park on the slope, but if you must park on the slope, you can put enough stones and other temporary brakes under the wheels of the car after the car stops to prevent the car from slipping.
