Cart walking trolley with broken shaft protection device

Abstract

The invention discloses a cart walking trolley with a broken shaft protection device. The cart walking trolley comprises a balance beam 1, a half hinge 2, a trolley frame 6, a driving motor 9, a driving motor bracket 11, a motor protection frame 12, a driving shaft 4, a driven shaft 5, the broken shaft protection device 3, a driving wheel 7, a driven wheel 8, a hinge support 10, a baffling block I 13, a baffling block II 14 and a rail 15. The broken shaft protection device and a wheel on the other one unbroken driven shaft or driving shaft push against the rail, so that the trolley and parts above the trolley are temporarily and effectively supported to prevent a wheel on the broken shaft from directly pushing against an upper cover plate at the top of the trolley frame or to prevent one side of the lower part of the trolley frame from directly pushing against the rail to damage the trolley frame and even cause inclining or collapsing of a whole crane, and the whole trolley is effectively protected. Furthermore, gaps between the two sides of a groove of the broken shaft protection device and the rail are smaller than gaps between the two sides of rims of the driving wheel and the driven wheel and the rail, so that the abrasion of the wheels and the rail is prevented or alleviated, the service life of the wheels is prolonged, and the replacing frequency of the wheels is reduced.

Description

technical field [0001] The invention relates to a large-tonnage shipbuilding gantry crane traveling trolley, in particular to a cart traveling trolley with a broken shaft protection device. Background technique [0002] At present, large-tonnage gantry cranes are more and more widely used, and have the characteristics of large span, heavy lifting capacity, high lifting height, and high working level, which makes the design of the supporting traveling trolley particularly important. Especially when there is a broken shaft, the entire trolley and even the entire crane will collapse due to the design of the traveling trolley without relevant supporting protection measures. In addition, at present, the wheel gnawing on the rails of the traveling trolley of the cart occurs from time to time, resulting in serious wear of the wheel rim, and frequent wheel replacement is not only difficult but also costly. [0003] Therefore, how to avoid causing big accidents and reducing or avoid...

Problems solved by technology

Especially when there is a broken shaft, the entire trolley and even the entire crane will collapse due to the lack of relevant supporting protection measures in the design of the trolley.

In addition, at present, the wheels of trolleys on trolleys gnaw rails from time to time, resulting in serious wear of wheel rims, and frequent wheel replacement is not only difficult but also costly
