Description

Technical Field

[0001] The invention belongs to the field of lightweight foaming process refrigerated meat hook carriages, in particular to a lightweight foaming process refrigerated meat hook carriage structure and a manufacturing process thereof. Background Art

[0002] With the mandatory implementation of the country's new regulations on livestock and poultry transportation, live pigs from other places must be slaughtered and quarantined locally and then transported through the entire cold chain using refrigerated meat hook trucks, which has promoted a sharp increase in domestic demand for refrigerated meat hook trucks.

[0003] The traditional refrigerated truck meat hook body panels are all welded with a full metal frame. The top plate of the body is the largest load-bearing, so it is generally welded with B-type channel steel beams and thickened angle steel to form a pre-buried structure of the overall frame. The body assembly is also mostly connected by full metal frame welding to ensure the strength of the body structure. The weight of the traditional refrigerated truck meat hook body is nearly twice that of an ordinary refrigerated body of the same size.

[0004] The traditional refrigerated meat hook truck is too heavy, resulting in poor effective loading capacity, high fuel consumption cost, and greatly affecting the universality of logistics business. At present, in order to ensure the transportation efficiency of refrigerated trucks and the universality of logistics services, in the environment where theoretically the lighter the truck, the more market advantage it has, the traditional refrigerated meat hook truck technology has gradually withdrawn from the market.

[0005] To this end, the present invention provides a lightweight foaming process refrigerated meat hook compartment structure and a manufacturing process thereof. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0008] Preferably, a steel-wood structural beam is provided inside the bottom plate, and H-shaped polymer composite profile frames are provided on both sides of the steel-wood structural beam. The steel-wood structural beam and the high-strength polymer pultruded profile are riveted and welded to form an overall frame structure.

[0009] Preferably, high-strength steel roll-formed reinforcement ribs are arranged inside the side panels and the front panel, and a steel plate is welded to the bottom of the high-strength steel roll-formed reinforcement ribs. The high-strength steel roll-formed reinforcement ribs and C-shaped high-strength steel roll-formed steel are welded to form an overall suspended all-metal frame structure.

[0010] Preferably, an I-shaped high-strength steel cross beam and a C-shaped high-strength steel roll-formed steel are arranged inside the top plate, and the I-shaped high-strength steel cross beam and the C-shaped high-strength steel roll-formed steel are welded to form an integral frame embedded structure.

[0011] Preferably, the embedded reinforcement frames of the box body floor, side panels and roof panels are arranged in a one-to-one correspondence, and the corresponding high-strength steel I-beams and the steel-wood structure beams of the box body floor are connected by welding and bolts to form a cage-type all-metal frame structure of the refrigerated meat hook truck.

[0012] A manufacturing process of a lightweight foaming process refrigerated meat hook compartment structure comprises the following steps: S1. The cabin roof adopts a pre-buried frame structure welded by lightweight T700L high-strength steel I-beam and "U-shaped" T700L high-strength steel roll-formed steel, and then the open foaming process is used for overall foaming; S2. The floor of the box body adopts the overall frame structure of steel-wood structural beams and high-strength polymer pultruded profiles riveted and welded, and then the open foaming process is used for overall foaming molding; S3, the two side panels and front panel of the car body adopt the overall "suspended full metal frame" structure welded by "U-shaped" T700L high-strength steel roll-formed steel and "C-shaped" T700L high-strength steel roll-formed steel; S4. The reinforced ribs of the two side plates, top plate and bottom plate of the compartment are arranged one by one. The corresponding high-strength steel I-beam crossbeam and the steel-wood structure crossbeam of the compartment floor are assembled by welding and bolting to form a "cage-type full metal frame structure" for the refrigerated meat hook truck. S5. Perform secondary high-pressure perfusion on the cavity formed by the connection between the bottom plate, the side plate, the top plate and the front plate, and fill it with foam through the secondary high-pressure perfusion.

[0013] The beneficial effects of the present invention are as follows: 1. The lightweight foaming process refrigerated meat hook compartment structure and its manufacturing process described in the present invention are provided with suspended high-strength steel roll-pressed reinforcement ribs in the left and right side panels and the front panel, and continuous punching holes are designed on the high-strength steel roll-pressed reinforcement ribs to reduce their own weight. In addition, an I-shaped high-strength steel crossbeam is provided in the top plate of the compartment to replace the traditional full-channel steel frame structure, so that the self-weight of the new process refrigerated meat hook compartment is 25% lighter than the side plate of the traditional process meat hook vehicle. The self-weight of the new process refrigerated meat hook compartment is equivalent to that of the traditional process ordinary refrigerated trucks, which greatly enhances the logistics and transportation versatility and operational capacity of the new process refrigerated trucks. In addition, a polyurethane foaming cold bridge layer is filled on the outside of the high-strength I-beam to ensure the insulation effect of the compartment panel.

[0014] 2. The lightweight foaming process refrigerated meat hook car structure and its manufacturing process described in the present invention ensure the thermal insulation effect of the side panels by filling a polyurethane foam layer on the outside of the high-strength I-beam. The new process refrigerated meat hook car adopts a suspended metal frame structure, which greatly reduces the side panel cold bridge structure compared to the traditional process meat hook car straight-through metal frame structure, greatly improves the thermal insulation performance of the new process refrigerated meat hook car, and also greatly reduces the weight of the car body.
