Abstract

The invention relates to a fatigue strength detecting machine of a trundle brake sheet, which is characterized comprising a stand. The lower end of the stand is transversely provided with a motor which is connected with an electronic counter, and the electronic counter is connected with an inductive switch; the output shaft of the motor is connected with a retarding mechanism; one end of a rocker in a crank and rocker mechanism is connected with the retarding mechanism and the other end is connected with one end of a rotating shaft positioned above the rocker; and the other end of the rotating shaft is connected with a brake sheet driving mechanism. The brake sheet driving mechanism is provided with a driving arm and a trundle fixing mechanism, wherein the driving arm is fixed on the rotating shaft through a flat key and provided with a groove for blocking the front end of a brake handle of a trundle, the groove is positioned at one side of the rotating shaft, and the axial direction of the groove is parallel to the rotating shaft; and the trundle fixing mechanism is fixed on one side of the rotating shaft of the stand and positioned at the side opposite to the groove of the driving arm. The invention can detect the fatigue strength of the trundle brake sheet so as to ensure that the trundle brake sheet meets the requirement and improve the use safety of the trundle brake sheet.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection machine for detecting the fatigue strength of caster brake pads. Background technique [0002] In the international standard ISO22883-2004, the "fatigue detection of brake and locking device" is proposed for the casters and wheels of the transportation device with a speed below 1.1 m / s (4 km / h), and it is stipulated that the cycle is 10 times per minute. In the case of 5,000 testing cycles, if the brake and locking device does not produce any wear or continuous deformation that adversely affects the function, the test is passed. There are such regulations in ISO 22884-2004 and European caster standards EN 12530, EN 12532, and EN 12533. However, the casters produced in China have not passed the test of this project, and there is no testing machine for testing them. Therefore, it is not known whether the brake device of the casters, that is, the brake pads, meets the safety standa...
