[0045] Further solutions, such as Figure 2 , Figure 3 , Figure 4 As shown, a baffle 109 is installed on each of the front U-shaped frame 101 and the rear U-shaped frame 101 to increase the strength of the U-shaped frame 101 and to limit the axial movement of the oil cooler 4. When the fastener III used to fix the oil cooler 4 becomes loose, the oil cooler 4 can collide with the baffles 109 arranged in front and behind it to produce abnormal noise, which serves as a reminder to the operator to retighten the fastener III in time.

[0046] Further solutions, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the baffle 109 is composed of a right-angle plate 110 and an inner lining plate 111. The right-angle plate 110 and the inner lining plate 111 are provided with at least one coaxial threaded hole. The vertical plate of the U-shaped frame 101 is provided with a through hole II corresponding to the threaded hole one by one.

[0050] The auxiliary radiator bracket mentioned above is further described below.

[0051] like Figure 2 , Figure 3 As shown, the auxiliary radiator bracket 2 includes an L-shaped frame 201 and a pair of right-angle reinforcing plates 202 opposite to each other; the L-shaped frame 201 is composed of a vertical frame and a horizontal frame, the horizontal frame is fixed to the oil cooler bracket 1 by fasteners II (bolts 206, nuts 207 assembly), the vertical frame is fixed to the frame 5 by fasteners I, and the auxiliary radiator 3 is assembled on the horizontal frame; a pair of right-angle reinforcing plates 202 opposite to each other are welded at two right angles on the outer side of the L-shaped frame 201 to increase the strength of the L-shaped frame 201.

[0052] Further solutions, such as Figure 6 As shown, weight-reducing holes are opened on the right-angle reinforcing plate 202, which reduces the weight and provides workers with the function of operating tools to tighten the auxiliary radiator bolts.

The opening diameter size of the inner side surface of the vertical empty tube is larger than the opening diameter size of the outer side surface of the vertical empty tube, so as to facilitate inserting a tool to tighten the nut 204.

[0054] Further solutions, such as Figure 3As shown, a pad 205 is provided on the outer side of each of the two vertical empty tubes, and a plurality of through holes IV corresponding to the through holes III are provided on the pad 205. Bolts 203 are passed through the frame 5, the pad 205 and the vertical empty tubes, and the frame 5, the pad 205 and the auxiliary radiator bracket 2 are fixed together by tightening the nut 204.

[0055] In summary, the utility model provides a combined fixing bracket of an auxiliary radiator and an oil cooler, which is a modular fixing structure that can meet the structural requirements of different configurations, reduce the workload, remove the oil cooling bracket and pipeline to adapt to the gearbox configuration that only requires an auxiliary radiator, and add the oil cooling bracket to adapt to the configuration that requires both an auxiliary radiator and an oil cooler (see Figure 1 Add a pad at the connection between the auxiliary radiator bracket and the frame (see Figure 2 ), strengthen the connection hole between the auxiliary radiator bracket and the frame to prevent the connection hole of the auxiliary radiator bracket from being torn due to the weight of the auxiliary radiator and oil cooler due to vehicle bumps. For details of the pad, see Figure 3 Adding a rubber pad on the upper and lower sides of the oil cooler bracket can not only clamp the oil cooler, but also protect the surface of the oil cooler to prevent deformation. Since the oil cooler is fixed with a rubber pad, it is prone to loosening, so a baffle is added inside the oil cooler bracket (see Figure 3 ), while strengthening the oil cooler bracket, it can also limit the oil cooler (see Figure 4 ), the baffle plays a secondary fixing role. When the long bolts become loose, the oil cooler will collide with the baffle and make a strange sound, which will attract attention and be tightened in time. Install right-angle plates at the right-angle butt welds of the oil cooler bracket and the auxiliary radiator bracket (see Figure 3 ), to prevent problems such as plate cracking and weld cracking due to poor working conditions. Figure 6 Weight-reducing holes are opened on the right-angle reinforcement plate to reduce weight while providing workers with the function of operating tools to tighten the auxiliary radiator bolts.

[0056] The utility model also provides a mining dump truck, comprising a vehicle frame, an auxiliary radiator and an oil cooler, wherein the auxiliary radiator and the oil cooler are assembled on the vehicle frame through a combined fixing bracket of the auxiliary radiator and the oil cooler.
