Description

Technical Field

[0001] This utility model relates to the field of trucks, and in particular to a corrugated plate for the side box of a dump truck. Background Technology

[0002] Dump trucks are a common mode of transportation for freight transport. The cargo box of a truck is a box-shaped structure made up of cargo panels. Therefore, the structure of the cargo box directly affects the safety and efficiency of the vehicle's cargo transport. The existing traditional side box corrugated panels have flat surfaces for each convex and concave wave. The flat surfaces of the convex waves are prone to deformation. Under heavy loads, the cargo box is prone to expansion and deformation, affecting freight safety and the service life of the truck. Moreover, since the side box panels are made of steel plates, they are heavy, which affects the load capacity and increases fuel consumption. Therefore, the improvement and innovation of the corrugated panels of truck side boxes are imperative. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a corrugated plate for the side box of a dump truck, which can effectively solve the problems of easy deformation and expansion of the side box plate of the existing dump truck under heavy load and its own weight.

[0004] This utility model discloses a corrugated side panel for a dump truck, comprising a side panel body and a reinforcing plate. The side panel body is made of high-strength steel and consists of a corrugated plate formed by alternating and evenly connected planar convex and concave waves. Outwardly bent reinforcing ribs are welded to the planar convex waves of the corrugated side panel body. Side panel sealing plates are provided at both ends of the corrugated side panel body. The upper parts of both ends of the corrugated side panel body are connected to the upper parts of the side panel sealing plates via connecting devices. The lower part of the corrugated side panel body is connected to the truck bed via hinges, forming a hollow dump truck box.

[0005] This utility model has a novel and unique structure, a scientific and reasonable design, is sturdy and durable, and is lightweight. It can prevent the side panels from deforming and expanding under heavy loads, reduce the weight of the carriage, extend its service life, and improve transportation efficiency and economy, thus having significant economic and social benefits.

[0009] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings and specific circumstances.

[0010] Depend on Figure 1-3 The present invention discloses a corrugated side panel for a dump truck, comprising a side panel body made of high-strength steel. The corrugated side panel body 3 is an integral corrugated side panel body 3 composed of planar convex waves 3-2 and planar concave waves 3-1 evenly distributed and connected together. Outwardly bent reinforcing ribs 3-3 are welded on the plane of the planar convex waves 3-2 of the corrugated side panel body 3. Side panel sealing plates 4 are provided at the left and right ends of the corrugated side panel body 3. The upper parts of the left and right ends of the corrugated side panel body 3 are connected to the upper parts of the side panel sealing plates 4 via connecting devices 2. The lower part of the corrugated side panel body 3 is connected to the truck bed via hinges 1, forming a hollow dump truck box.

[0011] To ensure effectiveness and ease of use, at least one vertical reinforcing plate 5 is installed on the waveform side box 3 (only one is shown in the middle of the side box 3 in the attached figure).

[0012] The outward bending angle of the reinforcing rib 3-3 is 60-120°, and the lengths of the two bent sides are the same.

[0013] The connecting device 2 consists of a base 2-2, a pin 2-1, a wrench 2-3, and a fixing pin 4-1. The base 2-2 is fixed to the corrugated side box plate 3 by screws. The pin 2-1 is welded together on the base 2-2. The wrench 2-3 is rotatably mounted on the pin 2-1 through the shaft hole, forming the rotating structure of the wrench 2-3. The side box sealing plate 4 is equipped with a fixing pin 4-1, which is used for the upper hook of the wrench 2-3 to be locked onto the fixing pin 4-1, forming the fixing or opening and closing structure of the corrugated side box plate 3 and the side box sealing plate 4.

[0014] The side panel is a 3mm thick corrugated plate made of high-strength steel with a yield strength ≥680MPa and an elongation of 18%-21%.

[0015] When using this utility model, it can replace the original corrugated side panel of the dump truck. When the truck body needs to be opened, wrench 2-3 is turned to disengage the upper latch of the wrench from the fixing pin 4-1, thus separating the corrugated side panel 3 and the side panel sealing plate 4. Then, the corrugated side panel 3 and the side panel sealing plate 4 are lowered by rotating the hinge, which is convenient for loading and unloading. When closing, the operation is reversed (public technology). It is very convenient to open and close. As can be seen from the above structure, this utility model has a novel and unique structure, is easy to manufacture, and especially adds bent reinforcing ribs to the flat convex waves of the existing corrugated panel, which improves the strength of the corrugated panel and can effectively prevent deformation and expansion of the truck body under heavy load, thus extending its service life. The existing corrugated panel is changed from ordinary steel to high-strength steel, which reduces the weight of the truck body, increases the load capacity, and reduces fuel consumption caused by the weight of the truck body. The box body made of high-strength material is lightweight, has high hardness, and strong corrosion resistance, which can effectively reduce vehicle cleaning and maintenance costs, improve transportation efficiency and economy, and has significant economic and social benefits.
