The invention relates to the technical field of piggyback transport equipment, in particular to a tray auxiliary device.

Background

The railway piggyback transportation is mainly a multi-mode combined transportation mode that a road truck or a semitrailer without a tractor is loaded on a special railway vehicle for transportation. The piggyback transportation can exert the advantages of safety, rapidness, large transportation capacity, all weather, energy conservation, environmental protection and the like of railway transportation, and simultaneously brings railway transportation increment, increases transportation income and has good social benefit.

The road truck or the semitrailer without a tractor carrying the railway truck can be directly hoisted as shown in fig. 1. However, in the loading and unloading mode, the strength of the body of the highway truck or the semitrailer is required to adapt to the hoisting working condition, and the highway truck or the semitrailer is a special semitrailer. By adopting a direct hoisting mode, the highway truck or the semitrailer without the tractor has larger self weight and smaller load.

In order to adapt to the loading and unloading of the general semitrailer, a drop-hole type rigid tray is adopted for loading. The drop-hole type rigid tray needs a ground matching device, namely, the ground matching device is matched with the rigid tray or the flexible bracket in a concave-convex mode at the passing position of the wheels to form an approximate plane, so that the highway truck or the semitrailer can be conveniently and smoothly loaded and unloaded.

However, when the tray falls into the ground matching device at present, the problem of difficult alignment exists, the tray can fall into the ground matching device only by continuously adjusting the position, the loading and unloading efficiency is greatly reduced, and after the ground matching device is matched with the tray, the tire bearing surface is in a horizontal state. When the semitrailer inclination is great, lead to the tractor can't be linked with the semitrailer, influence semitrailer efficiency of unloading.
