Description

Technical Field

[0001] The utility model relates to a carriage and a semi-trailer thereof, in particular to a sectional side-dumping semi-trailer carriage and a semi-trailer thereof. Background Art

[0002] The existing side-unloading semi-trailer is an integral box structure. When unloading, the whole box is unloaded in a single direction on one side. There are certain disadvantages in special unloading environments. For example, when unloading in a narrow space, the front or rear section of the box cannot be turned over as a whole to unload, resulting in low work efficiency. At the same time, when the existing semi-trailer is unloading sideways, a small amount of goods will remain in the box, affecting the unloading speed. Therefore, how to realize the demand for segmented side unloading during unloading is a problem that needs to be solved urgently. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 A sectional side-unloading semi-trailer carriage shown in the figure comprises a frame 1, and also comprises no less than two independent carriages 3 mounted on the frame, a gap being formed between the two independent carriages 3 and capable of independent rollover, the front side and rear side of the independent carriage 3 being respectively connected to hydraulic cylinders 4, the hydraulic cylinders 4 driving the independent carriage to roll over; the hydraulic cylinders 4 are mounted on the frame, and the output end thereof is connected to the top of the side of the independent carriage.

[0020] By setting up independent carriages, each carriage can be turned over and unloaded separately, meeting the unloading needs in special circumstances. The hydraulic cylinder drives the independent carriage to turn over and unload. The hydraulic cylinder is set on both sides of the independent carriage, so that the turning angle of the hydraulic cylinder is larger. A support platform is set on the side of the independent carriage away from the hydraulic cylinder. When the independent carriage turns over, its side can be turned over and rest on the support platform to prevent the carriage from shaking during unloading.

[0021] like Figure 3 As shown, one side of the independent compartment 3 has a side panel 31 that opens inwards, and the outer side of the side panel 31 is detachably connected to the frame through a locking piece. When unloading the vehicle, the locking piece is opened to facilitate the inward movement of the side panel. The bottom of the side panel 31 is connected to a movable sliding plate 32 through a pin shaft. The sliding plate 32 is located on the bottom surface of the independent compartment. The free end of the sliding plate 32 is connected to a telescopic plate 33. The sliding plate 32 and the telescopic plate 33 together form the bottom plate of the independent compartment. The end of the sliding plate 32 close to the telescopic plate is connected to a tensioning mechanism 6.

[0022] Specifically, a step is formed at the free end of the sliding plate 32, the telescopic plate 33 is engaged with the step surface, and a chain 61 is connected to the end surface of the sliding plate 32. Slide blocks 34 are symmetrically formed at the bottom surface of the sliding plate 32 near the inner wall of the independent compartment, and a slide groove matching the slide block is formed on the bottom surface of the independent compartment 3, and the sliding plate 32 can slide along the bottom surface of the independent compartment.

[0023] A side plate is provided on the side where the independent carriage is overturned, and the side plate is hingedly connected to the sliding plate, so that when the sliding plate moves along the slide groove, the side plate and the sliding plate can change from a vertical state to a horizontal state. Since the free end of the sliding plate is set to a step shape, after the telescopic plate is fitted with the step surface, a cavity is formed at the bottom of the telescopic plate, so that the chain can pass through the cavity and connect with the end of the sliding plate. Therefore, when the winding wheel reels the chain, the chain drives the sliding plate to slide along the slide groove. During the sliding process of the sliding plate, since the sliding plate abuts against the telescopic plate, the telescopic plate moves along with it and gradually shortens as the sliding plate slides toward the inside of the carriage, until the side plate and the sliding plate are on the same horizontal line, that is, the right angle between the side plate and the sliding plate is straightened. During the sliding process of the sliding plate, the goods on the bottom plate move along with it, and then slide down along the straight plate composed of the sliding plate and the side plate to complete the unloading, making the unloading cleaner.

[0024] In one embodiment, Figure 2 As shown, the tensioning mechanism 6 includes a chain 61 connected to the sliding plate and a winding wheel 62 , in which the chain 61 is wound, and the winding wheel 62 is inserted on a support shaft 63 through a bearing, and a torsion spring 64 is connected to the outer shell of the support shaft 63 .

[0025] Preferably, a box body 65 is installed at the bottom of the frame, a support shaft 63 is connected inside the box body 65, one end of the torsion spring 64 is connected to the box body, and the other end is connected to the winding wheel.

[0026] The chain is wound up by the winding wheel, so that the sliding plate is straightened, ensuring that the goods in the compartment are unloaded more cleanly when the vehicle is rolled over; the elastic force of the torsion spring is used to enable the winding wheel to wind up the chain.

[0027] A semitrailer comprises a sectional side-dumping semitrailer compartment.

[0028] In one embodiment, a plurality of groups of legs are arranged at intervals from front to back on the bottom surface of the frame 1, and each group of legs includes electric legs 2 symmetrically arranged on the left and right sides of the frame.

[0029] The unloading process of the utility model is as follows: the locking piece on the outer side of the side panel of a certain independent carriage is opened, and the hydraulic cylinder is started, and the hydraulic cylinder drives the carriage to tip over to one side. During this process, the goods in the carriage are dumped outwards. At the same time, the winding wheel winds up the chain, and the chain drives the sliding plate to slide along the sliding groove, and the sliding plate drives the side plate to move together. At the same time, the sliding plate generates pressure on the telescopic plate, so that the telescopic plate is gradually shortened until the side plate and the sliding plate are located on the same horizontal line. At this time, the goods located at the bottom of the carriage slide along the straight plate composed of the sliding plate and the side plate to the outside of the carriage, and the unloading of the goods in the carriage is completed.

[0030] The utility model aims to provide a segmented side-unloading semitrailer carriage and a semitrailer, so as to improve the use flexibility of the semitrailer, thereby improving the unloading efficiency of the semitrailer, and by tightening the chain through the tightening wheel, the semitrailer can be prevented from rolling over.

[0031] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
