Anti-falling device and method for wagon turnover device

Abstract

The invention discloses an anti-falling device and method for a wagon turnover device. The anti-falling device comprises automatic insertion pin mechanisms and gear racks, each automatic insertion pin mechanism comprises an air cylinder or a hydraulic cylinder, a connecting plate, an insertion pin rod, a sliding block base, an installing base and a compression spring, wherein the insertion pin rod penetrates through the sliding block base and the installing base, one end, penetrating through the installing base, of the insertion pin rod is hinged to one end of the connecting plate, and the other end of the connecting plate is hinged to a piston of the air cylinder or the hydraulic cylinder. A limit gasket is fixedly arranged at the position between each sliding block base and the corresponding installing base on each insertion pin rod, and the insertion pin rods penetrate through the compression springs, and the compression springs are arranged between the limit gaskets and the installing bases. One end, penetrating through the corresponding sliding block base, of each insertion pin rod is matched with the corresponding gear rack, and one end, penetrating though the corresponding sliding block base, of each insertion pin rod is matched with the corresponding rack, so that self locking of the automatic insertion pin mechanisms is achieved, and a turnover device operating table is prevented from falling. The anti-falling device can be applied to large-scale equipment and large-scale tools, and the safety coefficient of the wagon turnover device is greatly increased.

Description

technical field [0001] The invention relates to a fall prevention device and a fall prevention method thereof, in particular to a fall prevention device and a fall prevention method for a railway wagon turning machine. Background technique [0002] With the development of railway technology, the manufacturing process level of railway transport vehicles is constantly improving, and the manufacturing standards for railway freight car carriages have also been correspondingly improved. Repairing, grinding and other technical processing, that is, it is trimmed. For the convenience of repairing, manufacturers generally adopt turning machines to lift and turn railway wagons up and down at present. [0003] Such as figure 1 As shown, the railway wagon turning machine includes a turning machine frame 1, a turning machine operating platform 2, a chain lifting device, and a chain lifting device includes a rotating shaft 3 and a chain 4 matched with the rotating shaft 3, and the rotat...

AI Technical Summary

Problems solved by technology

But the safety factor of existing overturning machine is not high, and when the railway wagon carriage is trimmed, it is generally necessary for workers to stand on the bottom of the operating table, in the carriage or to operate on it. fracture, motor braking and mechanical self-locking failure, etc.), the console will fall down, causing serious production safety accidents and endangering the lives of workers
