DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-7 This application is described in further detail.

[0036] The present application discloses a gas engine branch air intake boost device installation structure. Figure 1 The mounting structure for a split-flow intake and supercharging device for a gas engine includes a cylinder mounted on a mounting base and a cylinder head 1 mounted on the cylinder. A first intercooler 2, a first supercharger 21, and a first intake pipe 22 are sequentially mounted on the cylinder head 1. Air passes through the first intake pipe 22 and enters the first supercharger 21 for supercharging. The compressed air is then cooled by the first intercooler 2 before entering the cylinder head 1. Furthermore, a second intercooler 3, a second supercharger 31, and a second intake pipe 32 are sequentially mounted on the cylinder head 1. Gas passes through the second intake pipe 32 and enters the supercharger for supercharging. Gas is then cooled by the second intercooler 3 and simultaneously enters the cylinder head 1 with the cooled air to mix. This prevents mixing of gas and air outside the cylinder head 1, reducing safety hazards.

[0037] Reference Figure 1 and Figure 2 An exhaust pipe 11 is also connected to the cylinder head 1, through which exhaust gases are discharged after combustion. A mounting frame 4 for mounting the first intercooler 2 is provided outside the first intercooler 2 and is mounted on the mounting base. A mounting frame 4 is also provided outside the second intercooler 3, and the first and second intercoolers 2 and 3 are mounted to the mounting frame 4 in the same manner.

[0038] Reference Figure 2 and Figure 3The mounting frame 4 has an opening 41, through which the first intercooler 2 is placed. A closure cover 5 is pivotally mounted at the edge of the opening 41. One side of the closure cover 5 is pivotally connected to the edge of the opening 41, and the other side is provided with a gusset plate 51. The gusset plate 51 engages with the edge of the opening 41, and a fixing member 52 for securing the closure cover 5 is provided on the gusset plate 51. The fixing member 52 can be a bolt. During installation, the first intercooler 2 is placed in the mounting frame 4, and the closure cover 5 is then rotated to secure the first intercooler 2 within the mounting frame 4. The closure cover 5 is then secured by the bolts threadedly engaging with the mounting frame 4.

[0039] Reference Figure 4 and Figure 5 To enhance the stability of the first intercooler 2, a limit plate 6 is installed within the mounting frame 4. The limit plate 6 is pivotally mounted within the mounting frame 4 on the side facing away from the opening 41. An abutment surface 61 is provided on the side of the limit plate 6 facing away from the interior of the mounting frame 4. The abutment surface 61 is angled away from the opening 41 near the edge of the opening 41. A mounting slot 42 is defined on the inner side wall of the mounting frame 4. An intermediate plate 7 slides within the slot 42. The intermediate plate 7 is positioned near the edge of the limit plate 6. A push rod 71 is provided on the intermediate plate 7, which abuts the abutment surface 61. In the initial state, the side of the limit plate 6 close to the opening 41 is tilted in the direction away from the inside of the mounting frame 4, and the first intercooler 2 is placed in the mounting frame 4, that is, placed on the side of the limit plate 6, and then the middle plate 7 is slid. The middle plate 7 drives the push rod 71 to abut against different positions on the abutting surface 61, and then drives the limit plate 6 to rotate in the direction toward the first intercooler 2 until the limit plate 6 abuts against the side of the first intercooler 2, thereby fixing the first intercooler 2 and improving the stability of the fit between the first intercooler 2 and the mounting frame 4.

[0040] Reference Figure 5 and Figure 6A slide plate 8 is slidably mounted within the mounting groove 42. The slide plate 8 slides in a direction toward the opening 41. The slide plate 8 is positioned on the side of the intermediate plate 7 facing away from the push rod 71. A slide groove 81 is formed on the slide plate 8 in a horizontal direction toward the intermediate plate 7. A slide bar 72 is positioned on the side of the intermediate plate 7 facing away from the push rod 71. The slide bar 72 is positioned within the slide groove 81 and slides horizontally within the slide groove 81. A guide groove 43 is formed on the inner wall of the mounting groove 42. The guide groove 43 is vertically disposed, and one end near the opening 41 is bent toward the interior of the mounting frame 4. The slide bar 72 extends from the side facing away from the intermediate plate 7 into the guide groove 43 and slides within the guide groove 43. When the slide plate 8 slides, the middle plate 7 is driven to slide through the slide rod 72. At the same time, the middle plate 7 drives the push rod 71 to move, driving the limit plate 6 to rotate. The slide plate 8 continues to move, driving the slide rod 72 to move to the bent end of the guide groove 43, so that the push rod 71 slides toward the limit plate 6 while moving, driving the limit plate 6 to move in the direction toward the first intercooler 2, thereby improving the stability of the cooperation between the limit plate 6 and the first intercooler 2.

[0041] Reference Figure 6 and Figure 7 In order to facilitate the adjustment of the position of the slide 8, a manipulation assembly 9 is provided on the mounting frame 4. The manipulation assembly 9 includes a manipulation rod 91, a manipulation plate 92 and a connecting rod 93. The connecting rod 93 is connected to the slide 8, and the connecting rod 93 and the slide 8 are arranged on adjacent two side walls of the mounting frame 4. The manipulation plate 92 is slidably arranged on the mounting frame 4 in the horizontal direction. A control groove 921 is formed through the manipulation plate 92. The control groove 921 is inclined on the manipulation plate 92. A control rod 931 is provided at one end of the connecting rod 93 close to the manipulation plate 92. The control rod 931 is arranged in the control groove 921, and the control rod 931 is in the control groove 921. The control groove 921 is slidably arranged along the length direction of the control groove 921, and the joystick 91 is rotatably arranged on the mounting frame 4. The joystick 91 is arranged along the sliding direction of the joystick plate 92. The joystick 91 is arranged on the side of the joystick plate 92 away from the connecting rod 93. A card slot 922 is provided on the side of the joystick 92 close to the joystick 91. A card strip 911 is provided on the side of the joystick 91 and the card slot 922 corresponding to the card strip 91. The card strip 911 is spirally arranged along the length direction of the joystick 91, and the side of the card strip 911 extends into the card slot 922.

[0042] When adjusting the position of the slide 8, rotate the control rod 931, and the control rod 931 drives the card strip 911 to rotate, so that different positions on the card strip 911 cooperate with the card slot 922, and then drive the operating plate 92 to slide along the length direction of the control rod 931 through the card slot 922. While sliding, the operating plate 92 drives different positions on the inner wall of the control groove 921 to abut against the control rod 931, and then drives the connecting rod 93 to slide in the vertical direction through the control rod 931. The movement of the connecting rod 93 drives the slide 8 to move, and the position of the slide 8 is adjusted.

[0043] Reference Figure 6 and Figure 7 The connecting rod 93 and the operating plate 92 are disposed on one side of the mounting frame 4 where the rotation axis of the closing cover 5 is located. The operating rod 91 is disposed near the opening 41 of the mounting frame 4, and the rotating side of the closing cover 5 is connected to the operating rod 91. When the closing cover 5 is rotated, the closing cover 5 drives the operating rod 91 to rotate, thereby adjusting the position of the push rod 71. This allows the closing cover 5 to secure the first intercooler 2 while also driving the limiting plate 6 to secure the first intercooler 2.

[0044] Reference Figure 4 and Figure 5 A slider 62 is rotatably provided on the side of the limiting plate 6 facing away from the opening 41. The slider 62 slides in the mounting frame 4 in a direction toward the interior of the mounting frame 4. An elastic member 63 is provided in the mounting frame 4 for driving the slider 62 in a direction toward the slider 62. After the slide rod 72 enters the bent portion of the guide groove 43, the push rod 71 can drive the limiting plate 6 to slide in a direction toward the first intercooler 2, so that the side surface of the limiting plate 6 abuts against the side surface of the first intercooler 2, further improving the stability of the fit between the limiting plate 6 and the first intercooler 2. A guiding slope 64 is provided on one side of the slider 62 close to the interior of the mounting frame 4. When placing the first intercooler 2, after the first intercooler 2 is placed in the mounting frame 4, it is moved until it abuts against the guiding slope 64, and the first intercooler 2 is continuously pressed. The guiding slope 64 drives the slider 62 to move in a direction away from the interior of the mounting frame 4 until the first intercooler 2 is placed between the sliders 62. The first intercooler 2 is then placed at a designated position in the mounting frame 4 for subsequent installation and fixation.

[0045] Reference Figure 4 and Figure 5Two sets of limit plates 6 are provided, one on each side of the first intercooler 2. Two sets of intermediate plates 7 and push rods 71 are also provided corresponding to the limit plates 6. Two sets of guide grooves 43 are also provided on the inner wall of the mounting slot 42. This allows the positions of the two sets of limit plates 6 to be adjusted simultaneously when the slide 8 moves, allowing both sets of limit plates 6 to simultaneously secure the first intercooler 2, further improving the stability of the first intercooler 2. A stop bar 65 is provided on the side of the limit plate 6 near the opening 41. The stop bar 65 is located on the side of the limit plate 6 near the interior of the mounting frame 4. The stop bar 65 engages with the edge of the first intercooler 2 to secure it.

[0046] The implementation principle of the present application is as follows: the air and gas are supercharged through the first supercharger 21 and the second supercharger 31 respectively, and then cooled through the first intercooler 2 and the second intercooler 3 respectively, and finally introduced into the cylinder head 1 respectively, and mixed outside the cylinder head 1 to reduce safety hazards. At the same time, the first intercooler 2 is placed in the installation frame 4, and then the closing cover 5 is rotated to a closed state. At the same time, the connecting rod 93 and the slide plate 8 are driven to move by the operating lever 91 and the operating plate 92, and the limit plate 6 is driven to rotate toward the first intercooler 2 by the push rod 71 until it abuts against the first intercooler 2, and then the closing cover 5 is fixed by the fixing member 52, and then the first intercooler 2 is fixed for installation.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
