Telescopic rotary locking device for railway platform wagon transportation container

Abstract

The invention relates to a telescopic rotary locking device for a railway platform wagon transportation container. The device is characterized by comprising a locking shaft assembly, a locking operation frame and a limiting round pin, wherein the locking shaft assembly consists of a lock rod, a lock seat, a positioning round sphere, a positioning spring, a spring compression screw, a baffle plate, an additional pipe and an operating handle; the top of the lock rod is provided with a lock rod head; the lower part of the lock rod head is provided with a cylindrical lock pillar; four hemispherical concave pits are uniformly distributed on the upper part of the lock pillar at equal intervals; a joint is arranged at the bottom of the lock pillar; the lock seat is a T-shaped cylinder; a through hole is formed in the center of the lock seat; a horizontal threaded hole vertical to the through hole is formed on one side of the lock seat; the threaded hole passes through the positioning round sphere and the positioning spring and is tightly fixed with the spring compression screw; the baffle plate is fixed at the bottom of the lock seat through the joint at the bottom of the lock rod and the additional pipe; the operating handle is fixedly connected at the bottom of the additional pipe; the locking operation frame comprises two parallel vertical plates which are arranged at interval; the two vertical plates are connected with each other through a front limiting plate and a rear limiting plate, and the vertical plates and the limiting plates are distributed in a square shape; the vertical plates are provided with a through hole respectively; and the limiting round pin is inserted into the through holes of the two vertical plates.

Description

technical field [0001] The invention relates to a locking device, in particular to a telescopic rotary locking device for railway flat car transport containers. Background technique [0002] At present, the existing container locking devices of railway flat cars mostly use flipping, sliding or a combination of the two to realize the conversion between the working position and the non-working position. These devices are heavy and the displacement line is easy to jam, requiring manpower When operating at the height of the loading surface of the container, the operator often has to climb onto the railway flat car and stand on the floor to operate downward. There is a risk of injury caused by climbing and slipping, and the operating efficiency is low. [0003] In addition, the lock head in the existing locking device basically has two types: straight platform and fixed platform, that is, the lock head and the lock seat are integrated. When the locking device is in the working po...

[0002] At present, the existing container locking devices of railway flat cars mostly use flipping, sliding or a combination of the two to realize the conversion between the working position and the non-working position. These devices are heavy and the displacement line is easy to jam, requiring manpower When operating at the height of the loading surface of the container, the operator often has to climb onto the railway flat car and stand on the floor to operate downward. There is a risk of injury caused by climbing and slipping, and the operating efficiency is low.

[0003] In addition, the lock head in the existing locking device basically has two types: straight platform and fixed platform, that is, the lock head and the lock seat are integrated. When the locking device is in the working position, there is only one state, and the lock head cannot rotate. This kind of lock head relies on the height of the lock head to prevent the overturning of the container. Even if the lock head has a boss, because the direction of the boss can only be arranged in the longitudinal direction of the container, it can only effectively prevent the container from overturning in the longitudinal direction. The effect is not obvious, and the container is easy to overturn when the railway flat car passes through the curve or the elevated line with cross wind
