The invention provides a pin roll detection device used for detecting the stress of a pulley pin roll. The pin roll detection device comprises a bracket, a pulley, a pin roll sensor and a locating component, wherein the pulley is rotatably connected with the pin roll sensor; two ends of the pin roll sensor are rotatably connected with the bracket; the locating component is provided with a first connecting end, a second connecting end, and a third connecting end; the second connecting end and the third connecting end are connected with the first connecting end; the second connecting end is provided with a first spacing hole; the third connecting end is respectively provided with a second spacing hole; the first connecting end and the end part of the pin roll sensor are fixed; the first spacing hole and the second spacing hole are positioned on a same plane with the sliding chute of the pulley; and the first spacing hole and the second spacing hole are symmetrically arranged on two sides of the stress central line of the pulley. The pin roll detection device can be used for accurately detecting the stress of the pulley pin roll. In addition, the invention further provides an engineering machine provided with the pin roll detection device.
Description
technical field [0001] The invention relates to mechanical detection technology, in particular to a pin shaft detection device for detecting the force of a pulley pin shaft; in addition, the invention also relates to a construction machine with the pin shaft detection device. Background technique [0002] At present, the pin sensor is widely used in technical fields such as weighing, overload protection, and anti-overturning, and it provides convenience for solving related technical problems. [0003] Generally, the pin sensor includes an elastic pin and a sensor element. The elastic pin is hollow inside and forms a cavity, and the sensor element is arranged at a corresponding position in the cavity as required. When in use, the pin shaft of the pin shaft sensor is directly set on the detected part to replace the function of the original component; take the application of the pin shaft sensor in the pulley as an example, such as figure 1 As shown, the pulley 21 is rotatably...
