Multifunctional connecting device suitable for railway wagon hoisting

Abstract

The multifunctional connecting device comprises a lower jaw plate, an upper pressing plate and a rotating shaft, a through hole is formed in one end of the lower jaw plate, the other end of the lower jaw plate inclines upwards, the upper pressing plate comprises a hook part and a connecting part, the hook part is arranged at the upper end of the connecting part, and the lower end of the connecting part is rotationally connected with the middle of the lower jaw plate; the multifunctional connecting device comprises a through hole, a rotating shaft and a hanging ring, the rotating shaft is rotationally connected into the through hole, the two ends of the rotating shaft are exposed out of the two sides of the through hole, the hanging ring is in a U shape, and the two ends of the hanging ring are detachably connected with the two ends of the rotating shaft. Small-size deviation of the gravity center is automatically repaired through rotation of the hook and the rotating shaft, hoisting safety is guaranteed, the device is suitable for being used for connection of various traction beams and bogies, the device can be integrally removed by loosening the hanging ring and the axle during dismantling, operation is easy, and the device can be used for next time.

Description

technical field [0001] The invention belongs to the technical field of railway freight car packaging and transportation, and more particularly relates to a multifunctional connecting device suitable for the hoisting of railway freight cars. Background technique [0002] From the completion of the production of the railway freight car to the complete delivery to the user, the transportation of the whole vehicle must be involved during the period. At present, due to the influence of various factors such as the geographical policy and distance of the customer, the transportation of the whole vehicle is usually carried out by means of automobile transportation and shipping. However, no matter which of the above methods is adopted, the whole vehicle needs to be bundled and then hoisted onto the means of transport. In order to ensure the absolute safety of the hoisting and transportation process, the vehicle bogie and the vehicle body must be absolutely connected and fixed. Sinc...

AI Technical Summary

Problems solved by technology

Due to the current situation that there are multiple types of vehicles to be transported at the same time, affected by the body structure of different types of vehicles, it is difficult for a single type of vehicle connection device to be applicable to various types of vehicles

If different connection devices are customized for different models, the various parts are easily confused during on-site assembly, which brings great trouble to the operators

In addition, the current connection devices are generally designed for one-time use, and it is difficult to dismantle them in a non-destructive way, so they cannot be used again, resulting in more waste of materials and lower economic benefits
