Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1 , Figure 4 As shown, a debris blocking and protection mechanical device for a lower frame includes a mounting part, a protective part, and a hinge assembly. The mounting part is located on the guide side of the upper top plate of the longitudinal beam 6. The protective part is arranged above the buffer space between the guide wheel 11 and the longitudinal beam 6. The hinge assembly is used to connect the protective part and the mounting part, and the protective part can rotate around the hinge point. When the guide wheel 11 is not subjected to impact buffering, the protective part falls down under its own weight and adheres to the upper top plate of the longitudinal beam 6, covering the buffer space between the guide wheel 11 and the longitudinal beam 6. When the guide wheel 11 is subjected to impact buffering, the protective part contacts the guide wheel 11 and lifts up, rotating around the hinge point.

[0023] The following provides a further explanation of the specific structure of the aforementioned mounting section.

[0024] like Figure 1 , Figure 2 As shown, the mounting section includes a mounting plate 1 and a connecting component connected to the mounting plate 1 and to the hinge assembly.

[0025] Further options, such as Figure 1 , Figure 2 , Figure 4 As shown, the mounting plate 1 is fixed to the top plate of the longitudinal beam 6 by fastening components. By loosening the fastening components, the mounting plate 1 can move along the length of the longitudinal beam 6, adjusting the installation position of the mounting plate 1 on the top plate of the longitudinal beam, thereby adjusting the coverage position of the protective part to match different sizes of buffer space.

[0026] Preferred solutions, such as Figure 1 , Figure 2 , Figure 4As shown, the fastening components are bolt 9 and washer 10. The mounting plate 1 is provided with an elongated hole 13 extending along the length of the longitudinal beam 6. Bolt 9 passes through washer 10 and elongated hole 13 and is screwed into threaded hole on top plate of longitudinal beam. By tightening and loosening bolt 9, fastening and separation between mounting plate 1 and top plate of longitudinal beam are achieved.

[0027] It should be noted that in the embodiment shown in the attached drawings, there is a symmetrically arranged elongated hole 13 on each side of the mounting plate 1, and two bolts 9 are provided in each elongated hole 13.

[0028] Further options, such as Figure 1 , Figure 2 , Figure 4 As shown, the connecting component consists of at least one cylinder 4, which is fixed to the edge of the mounting plate 1 near the protective part. The protective part is provided with at least one cylinder 14 near the edge of the mounting plate 1. The cylinders 4 and 14 are arranged alternately. When the cylinders 4 and 14 are aligned, the cylinders 4 and 14 are connected together by a hinge assembly.

[0029] It should be noted that in the embodiment shown in the attached drawings, there are two cylinders 4 on the mounting plate 1, and one cylinder 14 in the protective part. The cylinder 14 is located between the two cylinders 4, and the three cylinders are connected together by a hinge assembly after being aligned.

[0030] Further options, such as Figure 1 , Figure 4 As shown, the hinge assembly includes a pin 2 and a cotter pin 5. The pin 2 passes through the aligned cylinders 4 and 14, and the cotter pin 5 is inserted into the pin 2 to achieve axial positioning of the pin 2.

[0031] It should be noted that the hinge assembly is not limited to the pin 2 and cotter pin 5 mentioned above; it can also be a bolt or nut assembly.

[0032] The following provides a further explanation of the specific structure of the aforementioned protective section.

[0033] like Figure 1 , Figure 3 , Figure 4 As shown, the protective part includes a shielding component, a connecting component, and a contacting component; the shielding component is used to cover the buffer space; the connecting component is fixed to the edge of the shielding component near the mounting part for connection with the hinge assembly; the contacting component is fixed to the edge of the shielding component near the guide wheel 11 for contacting the guide wheel 11.

[0034] Further options, such as Figure 1 , Figure 3 , Figure 4 As shown, the shielding component, connecting component, and contact component are all formed by bending a single plate.

[0035] In a preferred embodiment, the front part of the plate has a concave structure in the middle and a convex structure on both sides. The convex parts on both sides are rolled up to form two coaxially arranged cylinders 12, which constitute the contacting parts. The rear part of the plate has a convex structure in the middle and a concave structure on both sides. The convex part in the middle is rolled up to form a cylinder 14, which constitutes the connecting parts. The blocking parts are implemented as follows: the middle part of the plate is set as an inclined structure with a high front and a low rear, and each end along the width direction of the longitudinal beam is bent downward to form a symmetrically arranged L-shaped structure.

[0036] Further options, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the mounting part is a symmetrical welded structure on the left and right, and the protective part 3 is a symmetrical bent structure on the left and right. During normal operation, the protective part 3 is close to the top plate of the longitudinal beam. When the guide wheel 11 is impacted and buffered, the two cylinders 12 at the front of the protective part 3 come into contact with the tread of the guide wheel and are lifted up, rotating around the pin 2. When the guide wheel 11 returns to normal operation, the protective part 3 falls down under gravity and is close to the longitudinal beam 6 again.

[0037] The following describes the installation process of the aforementioned debris blocking and protection mechanical device on the lower frame longitudinal beam: like Figure 4 As shown, since the chassis of a vehicle includes two track assemblies 7 and two longitudinal beams 6, therefore, Two underframe debris blocking and protection devices 8 need to be installed on each vehicle, one on each longitudinal beam. The installation process of one underframe debris blocking and protection device 8 is illustrated below. Specifically, the underframe debris blocking and protection device 8 is installed on the longitudinal beam 6 using bolts 9 and washers 10. It should be noted that when initially installing the underframe debris blocking and protection device 8, the mounting bolts 9 are placed at the rightmost end of the elongated hole in the mounting plate 1. As the tracks wear down during operation, the underframe debris blocking and protection device 8 can be gradually moved forward to better prevent debris such as coal and stones from falling into the longitudinal beam.
