A mine dump truck wet disc brake hydraulic system, including main control valve, one end of main control valve is connected pressure oil source, the other end is connected front brake system and middle and rear brake system, front brake system includes brake pedal, front axle proportional control valve group, front axle brake valve group and front brake cylinder, middle and rear brake system includes brake pedal, slow running valve, middle and rear axle brake valve, rear axle proportional valve group, relay valve group, rear axle brake cylinder and middle axle brake cylinder, the utility model discloses a mine dump truck wet disc brake hydraulic system can realize manual operation brake and line control remote brake function, reaches unmanned operation's requirement, is used for unmanned vehicle or auxiliary driving, and in order to adapt to the distance of middle and rear axle of three axle vehicle and the distance of main brake valve group is longer, two relay valve groups are added, brake corresponding speed is improved, faster brake response is realized, makes travel more safe.

The utility model relates to a transmission system for a small bar line packing machine head. Comprising a main control servo motor, a speed reducer, a main transmission gear, an electromagnetic clutch gear A, an electromagnetic clutch gear B, a main transmission shaft, a shaft-mounted flange A, a shaft-mounted flange B, an electromagnetic clutch A, an electromagnetic clutch B, an electromagnetic brake A, an electromagnetic brake B, a wire feeding disc wire channel wheel, a transmission bevel gear A, a transmission bevel gear B, a connecting rod shaft, a wire meshing air cylinder and an air cylinder tail tip. The utility model has the beneficial effects that the core transmission chain can reduce the transmission stage number and shorten the maintenance time; quick braking response can be achieved, and the wire feeding length error is reduced; unification of power sources of wire feeding and wire biting actions is ensured, and signal delay is avoided; complex electric control synchronization in a traditional packer system is avoided, and the defect that packing is not compact or wires are wasted is overcome. Abrasion caused by frequent start and stop is reduced, faults caused by continuous operation of equipment are greatly reduced, and maintenance cost and shutdown loss are also greatly reduced.

The utility model relates to the technical field of band-type brakes, in particular to a band-type brake torque dynamic compensation adjusting device which comprises a base, a band-type brake body is arranged at the top of the base and connected with a band-type brake braking torque detecting device, and a transmission shaft is integrally formed on the front side of a band-type brake wheel of the band-type brake body. An auxiliary braking assembly is arranged at the top of the base and located in front of the band-type brake body and comprises a fixed vertical plate installed on the front side of the top of the base through bolts, a rotating block is rotationally connected to the rear side of the fixed vertical plate, a braking wheel is arranged on the outer wall of the rotating block, and a dynamic compensation assembly used for braking the braking wheel is arranged at the top of the base. According to the band-type brake torque dynamic compensation adjusting device, through the linkage design of the auxiliary braking assembly and the dynamic compensation assembly, a redundant braking system is formed, secondary braking force is provided when braking force of the band-type brake body is reduced, and the safety redundancy capacity of an elevator system is remarkably enhanced.
