A water retaining flat iron 6 is welded around the inner bottom surface of the skeleton 1 near the heat insulation and thermal insulation layer 2, and a composite heat insulation board 3 is installed on the water retaining flat iron 6. As Figure 4 shown, a U-shaped profile 9 is installed on the top of the composite heat insulation board 3 to limit and fix the upper end of the composite heat insulation board 3. The U-shaped profile 9 is limited by a fixed profile 10, and the fixed profile 10 is welded to the skeleton 1. One end of the U-shaped profile 9 away from the heat insulation and thermal insulation layer 2 vertically extends out of the installation edge, which is convenient for installation and serves as a support for the composite heat insulation board 3 at the ceiling 4.
[0029] Among them, asFigure 3 As shown in the figure, a sandwich layer for guiding the condensate is formed between the heat insulation layer 2 and the composite heat insulation board 3. The bottom of the sandwich layer is connected to the condensate pipe 5, which is used to discharge the condensate generated between the sandwich layers and reduce the loss of heat or cold at the same time.
[0030] As Figure 6 shown, a hose 11 is connected to the drain hole in the lower side groove of the window pocket 12 on the skeleton 1, and the other end of the hose 11 is connected to the sandwich layer between the heat insulation layer 2 and the composite heat insulation board 3, which is used to drain the condensate generated on the window.
[0031] It should be noted that for the components fixed by welding methods such as the water retaining flat iron 6 and the fixed profile 10, the fixing method is not limited to welding during actual installation, and those skilled in the art can make a suitable choice according to actual needs.
[0032] At the same time, the heat insulation layer 2 is selected from, but not limited to, heat insulation materials such as rock wool, glass wool, ceramic surface, and spraying materials.
[0033] In one embodiment, a water storage tank is also provided inside the lower bin 16, and the water inlet is connected to the condensate pipe 5, which is used to collect the condensate water for vehicle use.
[0034] As a further improvement: there is a gap between the bottom of the heat insulation layer 2 and the inner bottom surface of the skeleton 1, and this gap and the water retaining flat iron 6 form a water tank. An anti-rust coating is provided on the skeleton 1 and the water retaining flat iron 6 in this water tank area, and the anti-rust coating uses epoxy resin. A number of groups of stud nails 7 are fixed on the skeleton 1, and the heat insulation layer 2 is attached to the skeleton 1 and the cap 8 through the stud nails 7.
[0035] In specific implementation, in combination with Figure 3 and Figure 7 shown, the water retaining flat iron 6 is installed with the composite heat insulation board 3, and the composite heat insulation board 3 located at the ceiling 4 is composed of several groups of spliced parts. The water retaining flat iron 6 is vertically arranged with the skeleton 1. The composite heat insulation board 3 is installed on the water retaining flat iron 6 through a groove rack, and the composite heat insulation boards 3 on the water retaining flat iron 6 are connected through male-female interfaces. The composite heat insulation boards 3 located at the ceiling 4 are connected through the installation of T-shaped profiles 13, and the T-shaped profiles 13 are fixed on the skeleton 1 through the ceiling profiles 14.
[0036] It should be noted that: The composite heat insulation board 3 is composed of two groups of metal plates and heat insulation materials, and the heat insulation materials are located between the two metal plates. The composite heat insulation board 3 in this embodiment is a composite rock wool board. The two groups of metal plates are galvanized steel plates or stainless steel plates, and the intermediate heat insulation material is rock wool, but it is not limited to the above materials, and those skilled in the art can make a suitable choice according to actual needs.
[0037] When using the heat insulation and heat preservation structure of the electric shovel cab, a sandwich layer is formed by the heat insulation layer 2 and the composite heat insulation board 3 to carry out heat preservation in this way. The middle sandwich layer reduces the conduction of heat and cold, and a structure for collecting condensed water is provided at the bottom of the sandwich layer. This structure is formed by the skeleton 1 and the water retaining flat iron 6. The condensed water generated between the sandwich layers flows into the structure for collecting condensed water and is discharged through the condensed water pipe 5. At the same time, an anti-rust coating is provided in this structure to prevent rusting due to immersion in water after long-term use.
