At present, safety measures for the elevator have a plurality of implementation schemes, but some elevator safety accidents still exist at present, such as the elevator car is not accurately stopped at a certain floor, the elevator car falls down and the like.
The invention content is as follows:
in view of the deficiencies of the prior art, an object of the utility model is to provide a hauler braking torque detection device, the device do benefit to whether the clamp force that detects brake caliper piece on the elevator hauler is reasonable to as a measure that improves elevator safety.
The utility model discloses hauler braking torque detection device, its characterized in that: the brake disc comprises a brake disc of an elevator tractor and a brake caliper sheet for braking the brake disc, wherein a concave groove is formed in the surface, facing the brake disc, of the brake caliper sheet, a strain gauge sensor is arranged at the bottom of the concave groove and electrically connected with a controller through a circuit, and the controller is electrically connected with a hydraulic cylinder for driving the brake caliper sheet to act; and a wear-resistant insert block is arranged on the strain gauge sensor in the concave groove.
Furthermore, the wear-resistant embedded block is in transition fit with the concave groove.
Further, above-mentioned depressed groove is the rectangle, offers the bar groove that extends to brake caliper piece edge at the depressed groove side, the circuit sinks into in the bar groove, wear-resisting abaculus also extends to the bar inslot in order to cover the circuit.
The utility model discloses hauler braking torque detection device's theory of operation: the surface of the brake caliper facing the brake disc is provided with a sunken groove, the bottom of the sunken groove is provided with a strain gauge sensor, and a wear-resistant insert block is arranged on the strain gauge sensor in the sunken groove; the strain gauge sensor is electrically connected with a controller through a circuit, and the controller is electrically connected with a hydraulic cylinder for driving the brake caliper sheet to act; therefore, when the hydraulic cylinder drives the brake caliper sheet to clamp the brake disc, the wear-resistant embedded blocks are pressed together, namely, pressure is generated on the strain gauge sensor, the pressure value is fed back to the controller through a circuit, the controller compares the pressure value according to a preset value, and when the pressure value is insufficient, the action of the hydraulic cylinder needs to be increased, so that the pressure value meets the requirement.
