Description

Technical Field

[0001] The utility model belongs to the technical field of semi-trailers, and in particular relates to a side-dumping trailer. Background Art

[0002] Semi-trailer is a kind of transfer vehicle widely used in daily production and material transfer. It is suitable for the transportation of bulk and scattered goods such as coal, ore, earth, building materials, etc. The car body adopts side-rolling and rear-rolling self-unloading methods, which can effectively load and unload bulk and scattered goods. The frame and car body longitudinal beams are welded with high-quality manganese plates. The cargo box is available in two types: dustpan and rectangular.

[0003] At present, most of the existing side-unloading trailers only have the function of tilting on one side. When unloading, they can only tilt to one side for unloading. This means that before unloading, the driver needs to adjust the direction of the front of the vehicle as much as possible according to the site requirements to ensure that the unloading direction is consistent with the direction of the cargo hold, which greatly increases the difficulty of unloading, reduces the unloading efficiency, and is not conducive to fast unloading. For this reason, we propose a side-unloading trailer. Utility Model Content

[0010] Preferably, buffer pads are provided around the top of the frame, and the buffer pads are fixedly mounted around the top of the frame by gluing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By setting a rotatable rotating sleeve and turntable between the frame and the carriage, the two can rotate synchronously under the action of the hydraulic rod and the layer plate, so that when the vehicle is measuring and unloading, the direction of the hydraulic rod can be directly adjusted by the rotating motor, and the carriage can be tilted to the side of the corresponding cargo compartment to achieve the purpose of rapid measurement and unloading, avoiding the need to adjust the direction of the vehicle head and turn around before unloading, thereby greatly improving the unloading efficiency.

[0013] 2. By arranging locating pins driven by electric push rods on both sides of the frame, cooperating with the locating grooves and locating blocks, as well as the pin holes opened on the two, it is convenient to control the separation of the frame and one side of the carriage when measuring and unloading. In conjunction with the locating pins on the other side, a certain degree of mobility is provided between the carriage and the frame, so as to facilitate the tilting of the carriage and achieve the purpose of measuring and unloading. The locating pins on both sides act together with the locating grooves and locating blocks at the same time, and can also play the function of positioning the carriage, thereby ensuring the stability of the carriage during transportation.
