The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1 to 6 in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Novel lightweight side curtain trailer, simple structure, stability are good, have realized the lightweight, have reduced the automobile body dead weight, have improved the transportation security, make the efficiency improvement of loading and unloading goods, application prospect is extensive.
Novel lightweight side curtain trailer, each component in carriage 1 adopts CKD spare part-equipment, convenient transportation, dismantlement, installation, change. The carriage 1 is of a frame structure and has no bottom plate, and under the condition of improving the transportation efficiency, the tray can be installed on the frame 2 in the carriage 1 in a matched mode, so that the purpose that the whole vehicle is dragged to transport by a belt is larger than or equal to 31.5 tons, and the phenomenon of insufficient tons is avoided.
Among the prior art, the top of side curtain trailer generally is whole glass steel material, steel flat board etc. according to produced actual conditions in long-term crashproof test and daily transportation, has found the easy fracture phenomenon that appears in top that adopts above-mentioned material to can not restore, need the wholeization to change, later stage use maintenance cost is high, and if not change in time appear tearing by a large scale in the long-distance transportation in-process of jolting in the later stage.
Based on above-mentioned phenomenon, top crossbeam assembly 13 installs special materials's hard top tarpaulin on top crossbeam assembly 13, all installs special materials's curtain cloth on left side railway carriage or compartment door 14, right side railway carriage or compartment door 15. Through long-time water spraying test, the hard top tarpaulin and the cord fabric made of the special materials are determined, compared with the materials, the composite material is anti-collision, waterproof and durable, is convenient to replace and maintain, has obvious effect advantages, and can reduce the dead weight of the vehicle body further under the conditions of reducing cost and improving the utilization rate.
The hard top tarpaulin and the cord fabric have the advantages of being waterproof, fireproof, mildew-proof and anti-freezing, being capable of preventing goods from being damaged by special environments such as rainwater, sunshine, fire and the like in belt-supported transportation, reducing the phenomenon that the goods are damaged by bags and bags, and effectively reducing loss.
In order to improve the loading and unloading efficiency, the left side carriage door 14 and the right side carriage door 15 are double-side curtain opening type carriage doors, double-side curtains are opened, and the small forklift can be matched with the left side carriage door and the right side carriage door to operate, so that safe, rapid and convenient loading, unloading, transporting and other operations of goods are realized, and the labor cost is further reduced.
In the prior art, the rail of the side curtain trailer is generally made of aluminum alloy, and through multi-party practice and customer experience feedback, the aluminum alloy rail often has collision deformation during loading and unloading, so that the technical problem that the aluminum alloy rail cannot be repaired after being damaged is solved. To above-mentioned technical problem, last track one 16, last track two 17, lower track one 18, lower track two 19 all adopt the rail way of sectional type iron system, can directly cut the welding change after bad damage, the replacement cost is compared and is reduced to the left side railway carriage or compartment door 14, the right side railway carriage or compartment door 15 of curtain formula are opened to the cooperation both sides, have realized two-way side curtain that opens and shuts, have solved the all aspects problem of whole change and goods loading.
Furthermore, in the prior art, the side curtain vehicles generally have the condition that the opening and closing degrees of the curtain cloth of the left and right side doors 14 and 15 are not high, which is mainly reflected in that the doors are rigid to open and close and the operation difficulty is large.
