Abstract: A device for cage jamming buffer of large-tonnage hoisting system of ultra-deep shaft is provided. End cage jamming buffer mechanisms are added at both ends of an automatic wire rope tension balancing mechanism, wherein the end cage jamming buffer mechanisms include an end buffer module and an end fixing module, and the end buffer module and the end fixing module are respectively mounted on shafts of the automatic wire rope tension balancing mechanisms at two ends. The end buffer module mainly consists of a buffer bearing pedestal, a limit block, a buffer block, and a stop block sequentially mounted on the shaft of the automatic wire rope tension balancing mechanism at one end. The end fixing module mainly consists of a fixing bearing pedestal and a fixing block mounted on the shaft, wherein the fixing bearing pedestal is connected to a transmission gear by an adjusting bolt.

Abstract: The present invention discloses a single-drive bidirectional-crawling pipe-cleaning robot, including a front body assembly, a transmission assembly, and a rear body assembly. The transmission assembly is driven by a single power source, and a transmission effect of a connecting rod mechanism, a gear mechanism, and an equal-dwell cam mechanism is used to implement alternate retraction and support of the front body assembly and the rear body assembly in a radial direction and a telescopic motion in an axial direction between the front body assembly and the rear body assembly and at the same time implement synchronous rotation of a dredging cutter head, so as to implement bidirectional crawling and pipe cleaning work of the robot along a pipe.

Abstract: A hydro-viscous speed regulating device for heavy-load start of a belt conveyor is provided. An input shaft and an output shaft are connected through a spline tube, an inner friction plate set, and an outer friction plate set. The inner and outer friction plate sets are controlled by an inner oil cylinder and an outer oil cylinder respectively. Oil inlet and oil return of the inner oil cylinder and the outer oil cylinder are controlled by an oil inlet valve core and an oil return valve core automatically. During starting process, pressure oil enters into the outer oil cylinder, and pushes the outer friction plate set to be engaged to provide torque required by the output shaft.

Abstract: A movable belt breakage prevention and catching system for a belt conveyor includes a detection device, two tracks, a plurality of catching devices, and a control system. The detection device is mounted on the belt conveyor, and is configured to detect whether a belt of the belt conveyor has a crack. The two tracks are symmetrically arranged on both sides of the belt conveyor, and the plurality of catching devices are symmetrically arranged on the two tracks. The control system is configured to control the plurality of catching devices to simultaneously catch the belt firmly when the detection device detects that the belt has a crack; and after firmly catching the belt, each catching device is able to unidirectionally move along with the belt along the track where the catching device is positioned.
