The invention discloses a device and method for detecting brake distance of a hoisting mechanism on a crane. The bottom end of a pillar is connected to the front surface of a bottom plate through a base and bolts. Four corners of the back of the bottom plate are provided with walking wheels. The top end of the pillar is connected with a lifting arm extending outwards. One end of the lower portionof a wire rope penetrates through an inner chamber of the pillar, penetrates out of the top end of the pillar, winds across a pulley and is freely suspended through a guide wheel. The tail end of thewire rope clamps a weight through a wire rope clamp. A dial gauge is embedded in one face of the pillar, and a measuring rod on the dial gauge is in contact with a dial gauge striker, and the dial gauge striker is fixed on a guide slider. An action switch is fixed to the face, back to the dial gauge, of the pillar by bolting. One end of a roller on the action switch is in contact with the upper end of a switch striker through a rotating shaft. The device is interlocked with the hoisting mechanism of the crane to ensure the authenticity and synchronization of the switching action and braking ofa brake of the lifting mechanism. The action is sensitive and the measuring precision is high, so that the measured value is more accurate.
Description
technical field [0001] The invention relates to a detection device for a braking distance of a hoisting mechanism on a crane, which is particularly suitable for use in detecting various performances of the crane mechanism with various tonnages and various speed control modes. Background technique [0002] Most cranes will test the performance of the hoisting mechanism before they are officially put into use to ensure that the crane meets the design requirements and use requirements, one of which is to measure the braking distance of the hoisting mechanism. With the continuous development of the control system, the braking distance of the crane hoisting mechanism becomes smaller and smaller, and the error of the previous visual measurement method is getting larger and larger, which cannot meet the needs of the braking distance measurement. Contents of the invention [0003] The task of the present invention is to provide a more convenient, more accurate and reliable detecti...
