The invention discloses a device for detecting balance coefficient and whether a band-type brake holds tightly or not. The device comprises a base, a pressure sensor, a hydraulic pump, a controller, a handheld operating device and a retractable rod, wherein the pressure sensor is arranged on the base, the retractable rod and the hydraulic pump are abreast arranged on the pressure sensor, the controller is arranged on the hydraulic pump and the controller is connected with the handheld operating device. The pressure sensor senses pressure acting on the pressure sensor, processes and converts the pressure into an electric signal and transmits the electric signal to the controller; after the controller converts and processes the electric signal which is transmitted by the pressure sensor, the controller transmits the signal to the handheld operating device through a serial port, receives a pressure increasing command or a pressure decreasing command which is transmitted by the handheld operating device and controls corresponding valves of the hydraulic pump according to the corresponding signal which is obtained through computation, treatment and conversion by a micro control unit (MCU). The invention additionally discloses a method for detecting whether the band-type brake of an elevator holds tightly or not and the balance coefficient of the elevator. The method and the device not only can be used for simply, conveniently and safely detecting whether the band-type brake of the elevator holds tightly or not, but also can be used for simply, conveniently and accurately detecting the balance coefficient of the elevator.
Description
technical field [0001] The invention relates to a method and a device for detecting whether an elevator brake is tightly held and for detecting an elevator balance coefficient. Background technique [0002] The national standard GB7588-2003 requires that the elevator maintenance company must regularly (at least once a year) check whether the brake can be reliably braked. However, because the current method of checking the brake is cumbersome, and it is difficult or even impossible to do it, therefore, Accidents of falling down stairs or even cutting passengers due to the inability of the brake to brake reliably occur from time to time. [0003] The national standard GB7588-2003 requires the brake to be able to brake reliably when the elevator is descending with a load of 125%. The test method of prior art is to load the weight of 125% load on the car. For example, an elevator with a load of 1 ton needs to drag a 1.25-ton weight to test, that is, it needs to transport the 1...
