Problems solved by technology

[0002] The existing safety brake devices produced at home and abroad are usually only equipped with a safety gear on one side of the elevator car, which is convenient to provide braking force, but the braking effect is not good
If safety tongs are installed on both sides of the elevator car, several safety ropes may be required to pull the safety tongs. As the cost of safety ropes increases, the cost will also increase greatly
And when the elevator runs downwards beyond the rated speed, the pulling force generated by the speed limiter drives the safety gear device installed on the car to brake, but the existing safety gear device can only play a role in safety for the elevator running downward at overspeed. It has no safety protection effect on the elevator running upwards at overspeed, which leaves a safety hazard for the elevator operation

Embodiment Construction

[0021] Such as figure 1 As shown, the two-way braking device of the present invention includes a front housing 1, a front shaft part 2, a joystick 3, a front safety gear 4, a front shaft connecting rod 6, a long connecting rod 7, a rear case 8, a rear shaft part 82, a rear safety gear Clamp 84 and rear axle link 86 .

[0022] Such as figure 1 , image 3 and Figure 5 As shown, the front shell 1 of the present invention is provided with a front shaft portion 2 . The front shaft part 2 includes a front shaft 20 , a right bearing 222 , a left bearing 212 , a front upper lever 21 , a front lower lever 22 and a Z-shaped plate seat 23 . The axis of the front shaft 20 is the left-right direction, and the front shaft 20 is fixed to the front shell 1 through the right bearing 222 and the left bearing 212 . The inside of the cross section of the right bearing 222 and the left bearing 212 is a square hole. The square hole matches the cross section of the front axle 20, and the cros...

Abstract

The invention discloses a double-direction brake device, relates to an lift car brake device, in particular to a brake device capable of braking upward and braking downward, and aims at providing the double brake device which is good in braking effect, saves cost, and is capable of braking upward and braking downward. According to the double-direction brake device, an operation rod is connected with a brake safety rope, when brake is needed, the safety rope pulls the operation rod to enable a front shaft and a back shaft to rotate at the same time, and enable a front safety clamp and a back safety clamp to brake at the same time, so that the brake effect and the brake stability are greatly improved. Only one safety rope is needed to control the operation rod, so that the cost of safety ropes is saved. Meanwhile, the clamps driven by the front shaft and the back shaft have the functions of braking upward and braking downward, so that the double-direction brake device can brake upward and brake downward.

Description

technical field [0001] The invention relates to a brake device for an elevator car, in particular to a brake device for uplink and downlink bidirectional braking. Background technique [0002] Existing safety braking devices produced both at home and abroad are usually only provided with a safety gear on one side of the elevator car, which is convenient to provide braking force, but the braking effect is not good. If safety tongs are installed on both sides of the elevator car, several safety ropes may be required to pull the safety tongs. As the cost of safety ropes increases, the cost will also increase greatly. And when the elevator runs downwards beyond the rated speed, the pulling force generated by the speed limiter drives the safety gear device installed on the car to brake, but the existing safety gear device can only play a role in safety for the elevator running downward at overspeed. The protective function has no safety protection effect on the elevator running ...
