Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an adaptive relatively constant braking force device. Background technique [0002] In the existing emergency braking device, accidents often occur due to friction factors or changes in working conditions. When the coefficient changes, the braking force cannot be adjusted timely according to the change of the friction factor, and some small changes of the friction factor will seriously affect the braking ability. Due to different processing methods, surface protection, working conditions, manufacturing errors, or external factors such as rust and oil pollution, the friction factors will vary in a large range, and ordinary braking force devices will not be able to Safe braking and stopping under all working conditions. However, the braking force is determined jointly by the positive pressure and the friction coefficient. Therefore, the technical solution to solve the problem o...

It adjusts the feedback amount through the angle difference between the friction element and the self-adjusting part and the spring. The processing error of the angle has a great influence on the magnitude of the feedback, and the magnitude of the feedback force is not easy to control. Therefore, the patent exists under the same conditions. It is applicable to various working conditions. The P+Q value of the elevator should be more accurate. Since the P+Q value of the elevator will have a range when designing, this range will basically be enlarged, and then controlled by adjusting the balance coefficient on site. The addition and subtraction of heavy blocks makes the weight of the on-site elevator lighter than the design weight. This range is related to the control of the designer and requires very accurate control of the weight of the elevator. Therefore, the patent will exist in the actual elevator design and application. certain degree of difficulty
