[0020] The installation architecture of the hybrid mining truck with dual engines is used to install the first power assembly 6, the second power assembly 7, and the radiator assembly 8, and includes: engine subframe 1, front support 2, rear support 3, height adjustment seat 4, and tie rod assembly 5.

[0021] like Figure 2 The diagram shown is a structural diagram of the engine subframe 1 in this utility model.

[0022] The main frame of the engine subframe 1 includes: front roof plate 11, rear roof plate 12, front floor plate 13, rear floor plate 14, side upright plate 15, front upright plate 16, and rear upright plate 17. The overall structure has an I-shaped cross section.

[0023] The front top plate 11 and the rear top plate 12 are positioned opposite each other and are on the same horizontal plane, with the rear top plate 12 connected to the rear end of the front top plate 11; the front bottom plate 13 and the rear bottom plate 14 are positioned opposite each other and are on the same horizontal plane, with the rear bottom plate 14 connected to the rear end of the front bottom plate 13; the front top plate 11 and the rear top plate 12 are located above the front bottom plate 13 and the rear bottom plate 14, and two side upright plates 15 are respectively connected between the front top plate 11 and the rear top plate 12 and the front bottom plate 13 and the rear bottom plate 14, and are located on both sides; the front upright plate 16 is connected between the front top plate 11 and the front bottom plate 13, and the rear upright plate 17 is connected between the rear top plate 12 and the rear bottom plate 14.

[0024] The area of ​​the front top plate 11 is larger than that of the rear top plate 12, and the area of ​​the front bottom plate 13 is smaller than that of the rear bottom plate 14. This ensures that the weld beads of the top plates (front top plate 11, rear top plate 12) and the bottom plates (front bottom plate 13, rear bottom plate 14) are staggered, which makes the welding process more efficient and the structure more resilient.

[0025] Above the weld bevels of the front base plate 13 and the rear base plate 14, a matching welding plate 19 is welded to the outer side of the side upright plate 15, which facilitates the on-site welding of the first bending plate 51 and also provides structural support.

[0026] After the engine subframe 1 is generally welded, machine drilling is performed on the front top plate 11 and the rear top plate 12. Multiple front top plate mounting holes 111 are provided on both sides of the front top plate 11, and multiple rear top plate mounting holes 121 are provided on both sides of the rear top plate 12, serving as mounting holes for the front support 2 and the height adjustment seat 4.

[0027] Machine drilling is performed on the front base plate 13 and the rear base plate 14. Multiple front base plate mounting holes 131 and rear base plate mounting holes 141 are respectively provided on both sides of the front base plate 11 and the rear base plate 12, which serve as mounting holes for the engine subframe 1 and the frame.

[0028] After the engine subframe 1 is generally welded, holes for radiator installation are machined on the front of the front base plate 1. Multiple radiator installation holes 132 are provided on both sides of the front of the front base plate 1.

[0029] To strengthen the connection between the front top plate 11, the rear top plate 12 and the front bottom plate 13, the rear bottom plate 14, multiple reinforcing ribs are connected between the front top plate 11, the rear top plate 12 and the front bottom plate 13, the rear bottom plate 14.

[0030] like Figure 3 As shown, is Figure 1 Enlarged view of point A in the middle; as shown Figure 4 The figure shown is a structural diagram of the front support 2 in this utility model.

[0031] The front portions of the first power assembly 6 and the second power assembly 7 are each provided with a front support 2. The front support 2 is used to mount and fix the front mounting shafts of the first power assembly 6 (first engine) and the second power assembly 7 (second engine).

[0032] The front support 2 includes: a front support base 21, a cylinder 22, a pad 23, and a stiffening plate 24. The bottom of the front support base 21 has a front support mounting through hole 25 on its horizontal plate, and a bending plate through hole on its upper part. Connecting bolts pass through the front support mounting through hole 25 and the front top plate mounting hole 111, connecting the front support 2 to the top of the front top plate 11. The cylinder 22 is connected within the bending plate through hole, and the pad 23 connects the horizontal edge to the cylinder 22, serving to fix the cylinder 22. The cylinder 22 has an oil injection hole 26 on its side wall and a lubrication oil reservoir 27 on its inner wall; the oil injection hole 26 is used to inject lubricating oil.

[0033] The front support base 21 includes a front support horizontal plate and a front support vertical plate. The bottom edge of the front support vertical plate is connected to the side of the front support horizontal plate. The front support horizontal plate and the front support vertical plate are perpendicular to each other, and the front support vertical plate has a triangular shape. A stiffening plate 24 connects the front support horizontal plate and the front support vertical plate to strengthen the connection between them.

[0034] The front connecting shafts of the first power assembly 6 (first engine) and the second power assembly 7 (second engine) pass through the cylinder 22, connecting the first engine, the second engine and the front support 2.

[0035] A wear-resistant bushing is installed inside the cylinder 18 to prevent abnormal wear caused by vibrations during engine operation. Shock-absorbing pads are installed on both the upper and lower sides of the front support mounting hole 25.

[0036] like Figure 5 The diagram shown is a structural diagram of the rear support 3 in this utility model.

[0037] The rear support 3 is used to install and fix the rear ends of the first power assembly 6 (first generator) and the second power assembly 7 (second generator).

[0038] The rear support 3 is L-shaped and includes a rear support horizontal plate 31 and a rear support vertical plate 32. The bottom edge of the rear support horizontal plate 31 is connected to the side of the rear support vertical plate 32. The rear support horizontal plate 31 and the rear support vertical plate 32 are perpendicular to each other. The rear support horizontal plate 31 is provided with multiple rear support mounting through holes 33, and the rear support vertical plate 32 is provided with multiple rear support vertical plate through holes 34. The rear support vertical plate through holes 34 are used to connect the engine and the generator. Connecting bolts pass through the rear support vertical plate through holes 34 to connect the engine (first engine, second engine) and the generator (first generator, second generator) respectively.

[0039] The rear support mounting through hole 33 is used to connect with the height adjustment seat 4 or the engine subframe 1. A bottom pad 35 is provided at the bottom, and the bottom pad 35 is provided with a bottom pad through hole.

[0040] The rear support plate 32 is provided with a rectangular opening 37 for the operation of a torque wrench, facilitating installation. A side pad is provided on the side of the through hole 34 of the rear support plate, and the side pad is provided with a side pad through hole.

[0041] The bottom pad 35 and side pads are made of rubber pads for easy shock absorption. The rear support upright plate 32 is provided with a rear support reinforcing rib 36 on the side. The rear support reinforcing rib 36 is U-shaped and located outside the rectangular opening 35.

[0042] like Figure 6 The figure shown is a structural diagram of the height adjustment seat 4 in this utility model.

[0043] Since there is a height difference between the front and rear mounting points of the first power assembly 6 and the second power assembly 7, a height adjustment seat 4 is designed to compensate for the height difference.

[0044] The height adjustment seat 4 includes: an adjustment seat base plate 41, an adjustment seat top plate 42, and an adjustment seat connecting plate 43. The adjustment seat base plate 41 is located below the adjustment seat top plate 42, and the adjustment seat connecting plate 43 is connected between the adjustment seat base plate 41 and the adjustment seat top plate 42. The adjustment seat base plate 41 is provided with multiple base plate through holes 44, and the adjustment seat top plate 42 is provided with multiple top plate through holes 45.

[0045] The rear support 3 is located on top of the height adjustment seat 4. The connecting bolts are inserted into the top plate through hole 45 and the rear support mounting through hole 33 to connect the rear support 3 and the height adjustment seat 4 together.

[0046] Multiple height adjustment seats 4 are located on the top of the rear top plate 12, and connecting bolts are inserted into the mounting holes 121 of the rear top plate and the through holes 44 of the bottom plate to connect the height adjustment seats and the rear top plate 12 together.

[0047] Since the rear support mounting through hole 33 is a round hole and does not have the function of adjusting error, the bottom plate through hole 44 is an elongated hole, which is used to adjust the relative position of the height adjustment seat 4 and the rear top plate 12. This is to avoid misalignment of the mounting holes due to manufacturing errors, thus achieving two goals at once.

[0048] The adjusting seat connecting plate 43 has a rectangular opening 46, which provides operating space for tightening the wrench.

[0049] The radiator assembly 8 includes two radiator units, which are connected to the cooling chambers of the first engine and the second engine respectively through pipes. The radiator assembly 8 is welded together from the two radiator units and provides cooling functions for the first engine and the second engine respectively, so that the first engine and the second engine can work independently without affecting each other's output.

[0050] The radiator assembly 8 is designed with mounting feet at the bottom, and the mounting feet are provided with mounting feet through holes. Connecting bolts are inserted into the mounting feet through holes and the radiator mounting holes 132 to connect the radiator assembly 8 to the front upper part of the front base plate 1. A shock-absorbing pad is provided between the mounting feet and the radiator mounting holes 132 to eliminate the vibration transmitted by the engine subframe 1.

[0051] The tie rod assembly 5 includes a first bending plate 51, a second bending plate 52, and a tie rod 53. The first bending plate 51 and the second bending plate 52 are each provided with a bending plate through hole. The tie rod 53 has threaded sections at both ends, which pass through the bending plate through holes of the first bending plate 51 and the second bending plate 52, respectively, and are connected by nuts. The first bending plate 51 and the second bending plate 52 are respectively connected to the outer frame of the radiator assembly 8 and the side upright plate 15.

[0052] The first bending plate 51 and the second bending plate 52 are respectively provided with welding elongated holes, which are used for on-site welding to connect the outer frame and side upright plate 15 of the radiator assembly 8. Shock-absorbing washers or springs can be installed between the threaded sections and nuts to eliminate vibration. The tie rod assembly 5 prevents the radiator from tipping over due to the high center of gravity of the radiator assembly 8.

[0053] The specific steps for installing a dual-engine hybrid mining truck are as follows: Step 1: Assemble the engine subframe 1; Weld the front top plate 11 and the rear top plate 12 together, and weld the front bottom plate 13 and the rear bottom plate 14 together. Weld side upright plates 15 to the upper sides of the front bottom plate 13 and the rear bottom plate 14. Weld the front upright plate 16 and the rear upright plate 17 to the front and rear. Place the connected front top plate 11 and the rear top plate 12 on the upper part of the side upright plate 15, the front upright plate 16 and the rear upright plate 17, and then weld them together.

[0054] Step 2: Install the front support 2 and the rear support 3 on the top of the engine subframe 1; Two front supports 2 are placed on the top sides of the front top plate 11 respectively. Connecting bolts pass through the front support mounting holes 25 and the front top plate mounting holes 111 to connect and fix the front supports 2 and the front top plate 11. Two rear supports 3 are placed on both sides of the top of the rear top plate 12. The connecting bolts pass through the mounting holes 121 of the rear top plate and the mounting through holes 33 of the rear supports to connect and fix the rear supports 3 and the rear top plate 12. If the rear of the first power assembly 6 and the second power assembly 7 do not match the through hole 34 (mounting hole) of the rear support plate of the rear support 3, a height adjustment seat 4 needs to be installed between the rear support 3 and the rear top plate 12 to adjust the mounting hole position; the two height adjustment seats 4 are placed on both sides of the top of the rear top plate 12, and the connecting bolts pass through the mounting hole 121 of the rear top plate and the through hole 44 of the bottom plate to connect and fix the height adjustment seat 4 and the rear top plate 12; then the rear support 3 is placed on top of the height adjustment seat 4, and the connecting bolts pass through the through hole 45 of the top plate and the mounting through hole 33 of the rear support to connect and fix the rear support 3 and the height adjustment seat 4.

[0055] Step 3: Use a lifting device to lift the first powertrain 6 and the second powertrain 7 onto the engine subframe 1, and connect and fix the first powertrain 6 and the second powertrain 7 to the front support 2 and the rear support 3; If a height adjustment seat 4 is installed, connect and fix the rear of the first power assembly 6 and the second power assembly 7 to the height adjustment seat 4.

[0056] The front connecting shafts of the first engine of the first power assembly 6 and the second engine of the second power assembly 7 are inserted inside the cylinder 22; the connecting bolts pass through the through holes 34 of the rear support plate and are respectively connected to the rear of the first engine and the second engine.

[0057] The first powertrain 6 and the second powertrain 7 are mounted on the top surface of the engine subframe 1 via the front support 2, the rear support 3, and the height adjustment seat 4. The included angle between the axes of the first engine and the second engine is 6 degrees.

[0058] To avoid difficulties in removing the engine oil pan, the engine subframe 1 lacks a crossbeam in the middle. It's worth noting that the rear support 3 is bent inwards, making the outer boundaries for mounting the first powertrain 6 and the second powertrain 7 very compact, facilitating installation within the confined space of the chassis.

[0059] Step 4: Install and fix the radiator assembly 8 at the front of the engine subframe 1, and connect the tie rod assembly 5 between the radiator assembly 8 and the engine subframe 1.

[0060] Using a lifting device, the radiator assembly 8 is hoisted to the front of the engine subframe 1. After aligning with the holes, it is placed above the radiator mounting hole 132. The connecting bolts pass through the radiator mounting hole 132 and the mounting hole at the bottom of the radiator assembly 8 to fix the radiator assembly 8 to the front of the engine subframe 1. The first bending plate 51 and the second bending plate 52 are respectively welded to the side upright plate 15 and the outer frame of the radiator assembly 8. The threaded sections at both ends of the tie rod 53 pass through the bending plate through holes of the first bending plate 51 and the second bending plate 52 respectively. The threaded sections are connected with nuts to connect the tie rod assembly 5 between the radiator assembly 8 and the engine subframe 1.

[0061] The terminology used in this invention is descriptive and exemplary, and not restrictive. Since this invention can be embodied in various forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
