Embodiment Construction

[0032] The preferred embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0033] see Figure 1-3 , this embodiment includes two safety gears 1, rotating shaft 2, shift fork 3, torsion spring 4, short pull plate 5, pull head 6, long pull plate 7, pull connection end 8, left and right threaded rods 9, Closed rigging turnbuckle 10, cam 12, extension spring 13, etc. The safety gear 1 shown in this embodiment is a symmetrical progressive safety gear, and its inner rear part has an installation space for a lifting mechanism; if the safety gear body is not lifted The installation space of the pulling mechanism can also be increased through the safety gear body to obtain a space for installing the pulling mechanism.

[0034] Each safety gear 1 is provided with two movable wedges 1-1 and side plates 1-2.

[0035] The rotating shaft 2 transversely passes through and rotates the side plate 1-2 matching the safety gear, its inne...

Abstract

The invention discloses a brake device with integrated safety tongs and lifting mechanism. The brake device comprises the two safety tongs, and movable wedge blocks and side plates are arranged on the safety tongs. The lifting mechanism comprises two rotating shafts, two shifting forks and two short pull plates. The rotating shafts penetrate the side plates of the safety tongs on the same sides in a running fit manner. The parts, in the safety tongs, of the rotating shafts are fixedly connected with the first ends of the shifting forks, and the second ends of the shifting forks can jack up the movable wedge blocks upwards. The parts, outside the safety tongs, of the rotating shafts are fixedly connected with the first ends of the short pull plates, the second ends of the short pull plates on the two sides are each in running fit with one end of a connecting mechanism, and the short pull plates on the two sides are opposite in direction. The outer end of one rotating shaft is fixedly connected with the first end of a long pull plate, and the second end of the long pull plate is in running fit with a lifting head. Mounting efficiency and assembling precision are improved, and the safety risks on construction sites are reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical product manufacturing, and relates to a safety brake device for an elevator, in particular to a brake device with an integrated design of a safety gear and a lifting mechanism. Background technique [0002] The braking of the safety gear is through the action of the speed limiter linked with the lifting mechanism of the safety gear. The left and right lifting plates of the lifting mechanism drive the braking element of the safety gear to contact the guide rail, so that the safety gear on both sides of the guide rail are clamped on the guide rail at the same time to prevent Stop the elevator car. [0003] A search of existing technical literature found that the existing safety gear and the lifting mechanism both adopt a separate installation structure, which generally has the following disadvantages: [0004] 1. In order to realize the lifting function, the safety gear must add a lifting mechan...
