Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] From figure 1 It can be seen from the figure that the self-rescue elevator safety gear includes the original safety gear 1 of the elevator. The original safety gear 1 has a frame-shaped bracket 2, and the bracket 2 is formed with a groove 3 with a narrow upper part and a wider lower part. The elevator guide rail 4 is located in the groove 3 Inside, the two sides of the elevator guide rail 4 in the bracket 2 are provided with wedges 5 matched with the elevator guide rail 4 and the groove 3, the wedges 5 are connected with the speed limiter rope 6 of the lifting mechanism, and a new safety gear is added below the original safety gear 1. Set the lower safety gear 7, the safety gear 1 and the lower safety gear 7 are connected in series up and down, and a pneumatic control system 8 is installed between the safety gear 1 and the lower safety g...

Abstract

The invention discloses a self-help lift safety gear comprising an original safety gear of a lift. The original safety gear comprises a frame support, a funnelled groove is arranged in the support, and a lift lead rail is located in the groove; both sides of the lift lead rail in the support are provided with wedge blocks matched with the lift lead rail and the groove, and the wedge blocks are connected with a speed governor of a lifting and pulling mechanism. The invention is characterized in that a set of safety gears are added below the original safety gear; the safety gear is connected with the lower safety gears in series from top to bottom; a retractor device controlled by a control system is arranged between the safety gear and the lower safety gears. The lower safety gears comprise a lower frame-shaped support in which a lower groove is arranged; the lift lead rail is arranged in the lower groove; two sides of the lift lead rail in the lower support are provided with lower wedge blocks matched with the lift lead rail and the lower groove, and the lower wedge blocks are also connected with the speed governor rope of the lifting and pulling mechanism. The self-help lift safety gear can hold the lift lead rail to gradually climb when the lift is in a failure, and thus, a lift car can climb to the door opening position to open the lift car door so as to reach the self-help purpose.

Description

technical field [0001] The invention relates to an elevator safety device, in particular to a self-rescue elevator safety gear with self-rescue function. Background technique [0002] As we all know, safety gear is installed on elevators. This kind of safety gear contains a frame-shaped bracket. The center of the frame-shaped bracket has a groove that matches the elevator guide rail. With the spring, the wedge is connected with the lifting mechanism. The two wedges are narrow at the top and wide at the bottom, and the side adjacent to the rolling body is a slope, and the rolling body is against the slope. When the elevator goes down over speed, with the help of the speed limiter and the lifting mechanism, the two wedge-shaped blocks can be lifted up and clamped to the elevator guide rail, so that the car stops falling, and the car is fixed on the guide rail, so as to prevent the car from going down. "Squatting in the pit". And once the safety gear implements clamping bra...
