Description

Technical Field

[0001] This utility model relates to an exhaust heating conversion device for the upper structure floor, belonging to the field of heavy commercial vehicles. Background Technology

[0002] Currently, underbody heating in heavy commercial vehicles typically involves installing heating elements, such as resistance wires or heating films, within the underbody. When current passes through these elements, electrical energy is converted into heat energy, raising the underbody temperature and heating objects placed on it. However, underbody heating systems require space to install the heating elements and related control equipment. Maintaining the underbody temperature requires continuous power, which consumes significant amounts of energy, especially during prolonged use, resulting in relatively high operating costs. Furthermore, if the heating elements are of poor quality, improperly installed, or used for extended periods, safety issues such as electrical leakage and short circuits may occur, potentially causing injury to the user. Utility Model Content

Figure 1a , Figure 1b As shown.

[0010] The exhaust heating conversion device for the upper base plate of this utility model adopts a combination of a three-way pipe 3, a U-shaped pipe 12, a V-shaped clamp 11, a fixing bracket I4, a fixing bracket II10, a pipe clamp I13, and a pipe clamp II14. The three-way pipe 3 is a welded structure of a round pipe and a square box. The main structure consists of round pipes I302, II305, and III306 welded to the three sides of the square box 304. The lower end of round pipe I302 is inserted and welded to the upper surface of the square box 304. A flange 301 is welded to the upper end of round pipe I302, and a cylindrical positioning block 303 is welded to the cylindrical surface of round pipe I302. The right end of round pipe II305 is inserted and welded to the left surface of the square box 304, and a round flange is welded to the left end. The left end of I306 is inserted and welded to the right plane of the square box 304, with the right end being open. Two welding nuts 307 are welded to the front face of the square box 304. A baffle 313 is welded to the rotating shaft 312 and installed inside the square box 304. A rotating plate 309 is welded to the front end of the rotating shaft 312; both can rotate 90 degrees simultaneously. The rear end of the rotating shaft is fixed to the rear end face of the square box 304 by a spring 310 and a nut 311. Bolts 308 can fix the rotating plate 309 to the two welding nuts 307 respectively. The U-shaped tube 12 is a round tube bent at both ends by 90 degrees, with a round flange welded to each end face. The fixed bracket I4 is an L-shaped bent plate with two bolt mounting holes on the top and bottom of the bend. The fixed bracket II10 is a double-bent L-shaped bent plate with two bolt mounting holes on the top and bottom of the bend. The pipe clamp I13 is a semi-circular bent plate with two bolt mounting holes at one end and a rectangular hole at the other end, with an oblong hole on the semi-circular surface. Pipe clamp II14 is a semi-circular bent plate, with two bolt mounting holes at one end and a convex bent plate at the other end, used in conjunction with pipe clamp I13, such as... Figure 2 As shown.

[0011] like Figure 2 and Figure 3As shown, 1 is a U-shaped aftertreatment, 2 is a U-shaped aftertreatment fixed left bracket, and two bolts 7 are used to fix the fixed bracket 4 to the inside of the U-shaped aftertreatment fixed left bracket 2. One pipe clamp I13, one pipe clamp II14, two bolts 5 and two nuts 5 are used to fix the round pipe I302 of the tee pipe 3. Two bolts 8 and two nuts 9 are used to fix the fixed bracket II10 to the lower side of the U-shaped aftertreatment fixed left bracket 2. One pipe clamp I13, one pipe clamp II14, two bolts 5 and two nuts 5 are used to fix the round pipe III306 of the tee pipe 3. Then, two V-shaped clamps 11 are used to fix one end of the U-shaped pipe 12 to the air outlet of the U-shaped aftertreatment 1, and the other end is fixed to the round flange end of the tee pipe 305. The flange 301 of the tee pipe 3 is connected to the mounting base plate.

[0012] The exhaust heating conversion device for the upper structure base plate of this utility model has a simple structure, is robust and reliable, and is easy to operate and disassemble throughout the assembly process. When the rotating plate 309 is rotated to the horizontal position, the baffle 313 is in a horizontal state, which just blocks the lower port of the round pipe I302 of the three-way pipe 3. The exhaust gas after treatment is discharged normally into the atmosphere through the U-shaped pipe 12 and the right port of the round pipe III306 of the three-way pipe 3. When the rotating plate 309 is rotated to the vertical position, the baffle 313 is in a vertical state, which just blocks the left port of the round pipe III306 of the three-way pipe 3. The exhaust gas after treatment is passed to the upper structure base plate through the U-shaped pipe 12 and the round pipe I302 of the three-way pipe 3 to heat the upper structure base plate.

[0013] This utility model combines a tee pipe, a U-shaped pipe, a V-shaped clamp, a fixing bracket, and a pipe clamp for easy installation, improving installation process and assembly efficiency, while also enhancing the reliability of the after-treatment tail exhaust system.

[0014] The product described in this utility model can be used on heavy-duty trucks, providing a new solution for heating the superstructure floor.
