[0047] In the first connection mode, the anti-collision part 202 will prevent the cab 101 from turning over, but will not prevent the front cover 102 from opening. Figure 1 , Fig.10 and Fig.13 In this connection state, the cab 101 does not flip, the front cover 102 can be opened, and the entire front anti-collision device 200 can play a role in blocking small obstacles in front;

[0048] In the second connection mode, the anti-collision part 202 will not hinder the turning over of the cab 101 and the opening of the front cover 102, see Figure 2 , Fig.11 , Fig.14 and Fig.15 As shown; in this connection state, the cab 101 can be turned over and can be turned over to the extreme state, and the front cover 102 can be opened and can be opened to the extreme position. At this time, the front anti-collision device 200 can not only facilitate the maintenance and inspection of the condition of the cab 101, but also make enough space behind the cab 101 to facilitate the maintenance and inspection of the hydraulic cylinder oil tank hydraulic parts and the front end parts of the large box behind the cab 101;

[0049] In the third connection mode, the anti-collision part 202 will simultaneously prevent the cab 101 from turning over and the front cover 102 from opening, see Figure 3 , Fig.12 and Fig.16 At this time, the front space occupied by the entire front anti-collision device 200 becomes smaller, and at the same time it can also block small obstacles in the front.

[0050] Specifically, as an embodiment of the present invention: Figures 4 to 6 The front anti-collision device 200 further includes two reinforcing parts 203 which are respectively arranged on the left and right sides of the anti-collision part 202 and fixedly connected to the anti-collision part 202 .

In some other embodiments, the two front bumpers 202b can be rectangular or wavy in shape or in other regular or irregular forms, have the same length, and can be arranged in a cross-arranged manner or connected end to end and tilted.

[0060] Specifically, in the above embodiments, refer to Figures 4 to 6 The two front protection beams 202a of the anti-collision part 202 are fixedly connected with the two reinforcement parts 203 in a one-to-one correspondence.

[0061] Specifically, in the above embodiment, when the anti-collision portion 202 and the connection portion 201 are in the first and second connection states, refer to Fig.10 and Fig.11 Each reinforcement portion 203 is fixedly connected to the corresponding front anti-collision beam 202a and the longitudinal connecting member 201a by a first bolt 204, a second bolt 205, a third bolt 206 and a fourth bolt 207; when the anti-collision portion 202 and the connecting portion 201 are in the third connection state, refer to Fig.12Each reinforcement part 203 is fixedly connected to the corresponding front anti-collision beam 202a and the longitudinal connecting member 201a by a first bolt 204, a second bolt 205 and a third bolt 206. The first bolt 204 is mainly used as the rotation center of the anti-collision part 202; the second bolt 205, the third bolt 206 and the fourth bolt 207 are mainly used to fix the anti-collision part 202 and the connecting part 201.

[0062] Specifically, when the anti-collision portion 202 and the connection portion 201 are in the first and second connection states, refer to Fig.10 and Fig.11 The third bolt 206 and the fourth bolt 207 are both located in the arc-shaped hole 211 opened on the reinforcement portion 203 and the front anti-collision beam 202 a , and are located at both ends of the arc-shaped hole 211 .

[0063] Specifically, when the anti-collision portion 202 and the connection portion 201 are in the third connection state, refer to Fig.12 The third bolt 206 is located inside the arc hole 211 opened on the reinforcement 203 and the front anti-collision beam 202a, and is located at the bottom end of the arc hole 211, and the fourth bolt 207 is set on the front anti-collision beam 202a.
