Water leaving grid and mounting structure thereof

Abstract

The invention discloses a water leaving grid and a mounting structure thereof, wherein the water leaving grid comprises a floor, a plurality of T-shaped rails are arranged above the floor, the T-shaped rails and the floor are integrally formed, and a plurality of supporting beams are arranged below the floor; the floor is further provided with a support used for being hinged to a vehicle body; the plurality of T-shaped rails are arranged in parallel, and each T-shaped rail is arranged in the longitudinal direction of the vehicle body; a plurality of through holes are formed in the portion, between every two adjacent T-shaped rails, of the floor; the plurality of supporting beams are arranged in parallel, and each supporting beam is perpendicular to the corresponding T-shaped rail; and the supporting beams are provided with a bottom plate and web plates arranged on the two sides of the bottom plate, and the bottom plate and the web plates on the two sides form a U-shaped structure with an upward opening. The water leaving grid is integrally formed by integrally extruding an aluminum alloy, so that the structural strength is improved, the weight is reduced, the welding workload is reduced, the ventilation area is increased, the ventilation quantity is increased, and the air return quantity of an air conditioning system is ensured.

Description

technical field [0001] The invention relates to the technical field of refrigerated transportation equipment, in particular to a water-disengaging grid and its installation structure. Background technique [0002] When railway refrigerated goods are transported, there are usually water-free grids on the floor of the refrigerated transport vehicles. The grid flips up for easy cleaning. [0003] Existing refrigerated trucks are usually assembled and welded structures of aluminum alloy profiles or non-metal light structures. However, the manufacturing process of the welded structure is complicated, there are many welds, and the workload is large; the structural strength is low, it is tolerant to pressure loss, the ventilation area is small, and the ventilation volume is insufficient. The non-metallic metal light structure uses long fiber reinforced molding compound as raw material, which is easy to age and has a low service life. Contents of the invention [0004] The purp...
