    摘要： A fracture detection system and method for a dumbbell pin of a scraper conveyor. The system comprises a scraper conveyor, a wireless ranging apparatus (2), a wireless communication device, a support controller and a monitoring center. The wireless ranging apparatus (2) is mounted on a ramp plate ledge of a scraper conveyor chute (1), and has a laser range finder and a reflection target plate (24) for detecting a relative displacement between any two adjacent chutes. The wireless communication device realizes communication between the wireless ranging apparatus (2) and the support controller, and transmits the displacement of the laser range finder to the support controller in a wireless transmission manner. The support controller controls an action of the scraper conveyor chute (1). A monitoring center is electrically connected to the support controller, and can perform storage processing on relative displacement data of any adjacent chutes. In the method, by taking a relative displacement value between adjacent chutes as a reference, whether a fracture fault occurs in a dumbbell pin is judged, the position of the fractured dumbbell pin can be accurately determined, and a support controller controls a chute action, thereby having a high promotion and usage value.

    摘要： A drilling and bursting heading machine, comprising a drilling and bursting device (1), an angle control device, a forward-backward telescopic device and a cantilever type heading machine (2), wherein the drilling and bursting device (1) is mounted on a forward-backward moving component of the forward-backward telescopic device by means of the angle control device, and the forward-backward telescopic device is mounted on the cantilever type heading machine (2); the drilling and bursting device (1) comprises a fixing support (1-20), as well as a rock drill component and a bursting component fixedly mounted on the fixing support (1-20) respectively; the angle control device comprises a mounting base (1-15), an auxiliary rotary hydraulic motor (1-14), an adjustment hydraulic cylinder (1-13) and a main rotary hydraulic motor (1-12); and when the forward-backward moving component of the forward-backward telescopic device completely extends out, the distance from a front end of the drilling and bursting device (1) to a working plane is shorter than the distance from a front end of a cutting head of the cantilever type heading machine (2) to the working plane. The drilling and bursting heading machine has a compact structure and is able to implement quick drilling and bursting on a hard rock stratum having a rock hardness f greater than 10 without increasing the energy consumption, so that the heading efficiency is improved and potential safety risks are reduced.
