Train tail unit locking hook

Abstract

The train tail unit locking hook for locking train tail unit to train tail includes driving part, clamping part and casing. The driving part is one worm gear mechanism sealed inside the casing. The locking hook has reasonable and compact structure, and facilitates the assembling and disassembling of train tail unit without damage.

Description

technical field [0001] The present invention relates to a locking hook. More specifically, the present invention relates to a locking hook of a train tail main engine. The connection is firmly snapped. Background technique [0002] In recent years, in view of the cancellation of the guard car of the railway train, the disconnection of the carriages at the rear of the train has become a major safety hazard, so a variety of train tail confirmation devices or alarm devices have appeared in the prior art. As in Chinese patent documents 1118319A, CN2124172U and CN1142454A, this type of train rear wind pressure alarm device is disclosed. In addition, a variety of tailing devices have been put into practical application in China (such as CP-3 tailing device, ZTF tailing device, etc.). Most foreign railway trains are also equipped with similar end-of-row monitoring equipment. All these tail devices are generally detachably fixed to the tail of the train, and perform multiple func...

Problems solved by technology

[0003] However, due to the harsh working conditions of the train end device, it must withstand long-term vibration, knocking and impact, alternating humidity and heat, and strong interference during use. Moreover, with the marshalling of the train, it needs to be unhooked and returned every time it is used. , these factors will cause damage to the host at the end of the column

Among these factors, the problem of unhooking and hanging operation of the tail device is particularly prominent. In this operation, because most of the hook devices of the current tail device adopt the screw drive mode, it is inconvenient to install and disassemble, and the transmission part is exposed, which is easy to be damaged. The impact of rain and sand dust caused the transmission part to rust and become greasy, which caused the on-site staff to use tools to disassemble and assemble illegally, or even use a hammer to knock, directly causing damage to the equipment
