The other end of the curtain line is cut short, the threading operation of a curtain is completed, the problem that threading is difficult due to the fact that line holes of curtain pieces are not aligned is solved, the self-adjusting function is achieved, and the working efficiency is improved.

Wheelset vertical disassembly machine
ActiveCN107030472BImprove decomposition efficiencyHigh control precisionMetal working apparatusDecompositionEngineering
The present invention relates to the field of equipment machinery for railway passenger and freight cars and subway vehicles, in particular to a wheel set vertical decomposition machine, which includes a grasping and lifting rotating main machine and two unloading machines, and the two unloading machines are separately arranged in the Grab and lift the two sides of the rotating main machine. The grabbing and lifting rotating main machine includes a grabbing device, a lifting mechanism and a turning device. The grabbing device is installed on the lifting mechanism and driven to lift by the lifting mechanism. The lifting The mechanism is installed on the slewing device and is driven to rotate horizontally by the slewing device. The wheel pair is grabbed by the grabbing device, and when disassembled, the wheel pair is driven to rotate to either side and vertically Place it upright on the unloader on that side. The invention changes the disassembly method of the wheel set from horizontal to vertical, and the wheels will automatically fall and separate by their own gravity, and the press machine that cannot be completely separated can be restarted and unloaded, which greatly improves the decomposition efficiency and does not cause wheel axle defects.

Ratchet parking brake device for wheeled tractors
ActiveCN103615481BAccurate returnCompact structureHand actuated initiationsBrake actuating mechanismsCamIdler-wheel
The invention relates to a ratchet wheel parking braking device of a roller tractor. A limiting plate is provided with a guide groove, and an operating lever of a rocker arm assembly penetrates through the guide groove in the limiting plate to be hinged to a rocker arm shaft. An upper pin fixed on a rocker arm is arranged in a sliding chute of a hinged plate, the lower side of the hinged plate is hinged to a disk body of a camshaft through a lower pin, and the two ends of a first torsional spring are connected to the upper pin and the lower pin respectively. A cam, a parking braking stop block and a parking braking removing stop block are arranged on the end face of the disk body of the camshaft. A ratchet matched with a gear is arranged on the front upper portion of a ratchet wheel base on a ratchet wheel assembly, and the lower portion of the ratchet wheel base is arranged on a fixed shaft in a sleeved mode. The outer circumference of an idler wheel mounted on the side face of the ratchet wheel base is connected to the cam on the end face of the disk body in a pressing mode, the ratchet wheel base is provided with a limiting block corresponding to the parking braking stop block and a supporting seat corresponding to the parking braking removing stop block respectively. The two ends of a second torsional spring arranged on the fixed shaft in a sleeved mode are connected with the ratchet and a fixed seat respectively. The ratchet wheel parking braking device of the roller tractor is reasonable in structure, reliable in parking braking and free of maintenance.
