Unhooking device for railway vehicles

Abstract

The invention relates to an unhooking device for railway vehicles. The unhooking device consists of a transmission mechanism and a locking positioning mechanism, and is characterized in that the transmission mechanism comprises a transmission lever and a pulling rod, the tail end of the transmission lever is connected with a J-shaped part of a reverse V-shaped bent hook, the pulling rod is a round rod, one end of the pulling rod is hinged with the front end of the transmission lever, the other end of the pulling rod is provided with an operation handle, a flat pressing section is arranged on the pulling rod arranged at the front part of the operation handle, the locking positioning mechanism consists of a locking sheet and positioning pins, the locking sheet is an annular loop structure formed by doubling up a spring steel plate strip, one end of the locking sheet is in an annular shape, the other end of the locking sheet is a closed section formed by pasting the steel plates, positioning holes are formed in the closed section, the positioning pins are matched with the positioning holes, and the annular end of the locking sheet is sheathed on the flat pressing section of the pulling rod. The unhooking device has the advantages that the unhooking operation is more convenient and faster, the labor is saved, and the locking of a vehicle hook is more reliable.

Description

technical field [0001] The invention relates to a railway vehicle coupler buffer device, in particular to a railway vehicle coupler uncoupling device, which belongs to the field of railway vehicle coupler buffer devices. Background technique [0002] The coupler buffer device is an important part of the railway vehicle. Its function is to realize the connection between the locomotive and the vehicle or between the vehicle and the vehicle, to form a train, and to transfer and alleviate the shock generated during the operation or shunting and formation operation between the train and the vehicle. traction and impact. In short, the three major functions of the coupler buffer device are coupling, traction and buffering. The coupler buffer device is mainly composed of coupler, buffer, coupler opening device and coupler tail frame and other components. Couplers are divided into automatic couplers and non-automatic couplers according to the connection method. The most widely used...

Problems solved by technology

Years of use have shown that both the existing upper-action and lower-action hook opening methods have the hook opening action due to the free swing of the hook lifter, which causes the phenomenon of train separation and affects driving safety. The jumping pin is used to prevent the uncoupling, which also makes the uncoupling operation more complicated, and the anti-jumping pin is installed at the lower part of the coupler, which is not conducive to on-site operation, seriously affects the working efficiency, and brings great inconvenience to the railway operation
