Description

Double-box self-unloading trailer

Technical Field

The utility model relates to the technical field of transportation equipment, in particular to a double-box dump trailer.

Background

In order to improve the freight efficiency, a container semitrailer is often loaded with two containers at the same time on the premise of not overloading. And the common truck for loading bulk materials can be unloaded through a dump truck, and also can be unloaded through a hydraulic turning plate unloading device. However, the existing semitrailer with double containers cannot realize rapid unloading, so that the unloading efficiency of the double containers is low, the unloading time is long, and the freight efficiency is reduced.

To solve this problem, chinese patent publication No. CN218988196U discloses a hydraulic flap unloading device for double container unloading, which lifts and unloads the whole freight vehicle loaded with double containers by providing a large flap platform and being equipped with a hydraulic cylinder and a wheel stopper. However, this technical solution has the following problems: because the whole freight vehicle loaded with the double-box cargoes is lifted, the whole load weight is large, and the investment of the platform structure and the hydraulic system is excessive; the unloading position of the equipment cannot be easily changed after the equipment is put into operation. The Chinese patent document with the publication number of CN102923036A discloses a double-container semi-trailer rear unloading vehicle, a front carriage and a rear carriage with a hydraulic lifting system are arranged on a vehicle frame, so that the double-container transportation and self-unloading are realized, and the technical scheme has the advantages of small equipment investment and flexible unloading places. However, the following problems still exist in this technical scheme: firstly, two containers must be lifted and dropped according to a fixed sequence, the root is that the adjacent distance between the front carriage and the rear carriage is too small, if the rear container is not lifted to a yielding position, the front container cannot be lifted, as described in the beneficial effect in the literature, when the rear container is lifted, the rear container is lifted in place, the front container is lifted again, and after the front container drops, the rear container can be dropped; if the rear container is not lifted, the front container cannot be operated. Secondly, when the front container is unloaded, the bulk cargo can fall into the frame and the wheel set below the rear container, so that the bulk cargo is inconvenient to clean, if the bulk cargo is not cleaned, the normal falling of the rear container can be influenced, the lifting hydraulic system of the rear container needs to be kept in a lifting state for a long time, the falling action can be carried out after the cleaning work is completed, and the energy is wasted, so that the hydraulic system is easy to damage.
