The bolt is sequentially passed through one through hole, the hydraulic lock bolt 30, and the other through hole from one side of the suspension lock bolt bracket, and the bolt is fixed on the other side of the suspension lock bolt bracket by a nut.

[0044] The hydraulic control device 8 includes a hydraulic control unit 38 and a hydraulic control bracket 39. The hydraulic control device 8 is arranged at the front end of the right longitudinal beam 13 of the vehicle frame. The hydraulic control bracket 39 is fixedly connected to the front end of the right longitudinal beam 13 of the vehicle frame. The hydraulic control unit 38 is fixedly installed above the hydraulic control bracket 39 by four bolts.

[0046] When disassembling the cab fairing 14, open the hydraulic lock 21 through the hydraulic control unit 38 and take out the hydraulic lock bolt 30 from the hydraulic lock 21, and the whole cab fairing 14 can be disassembled from the vehicle frame 10.

[0047] The cab fairing 14 is disassembled and assembled by a detachable connection method of a hydraulic lock 21 and a hydraulic lock bolt 30. Only by controlling the switch of the hydraulic lock 21 through a hydraulic control device 8 can the cab fairing 14 be fixed to the vehicle frame 10, or the cab fairing 14 can be removed from the vehicle frame 10 as a whole. The operation is simple and fast, which can reduce the operation time of disassembling and assembling the cab fairing 14 and improve the work efficiency of disassembling and assembling the cab fairing 14.

[0048] Optionally, the suspension lock bolt bracket assembly can also be fixed to the bottom of the cab fairing 14 by other means.

[0056] When the hydraulic lock 21 is connected to the hydraulic lock bolt 30, the guide pin is inserted into the guide hole.

[0057] Specifically, the frame guiding device 6 includes a guiding fixed bracket 32 and a guiding sleeve bracket 33. The guiding fixed bracket 32 and the guiding sleeve bracket 33 are fixedly connected by welding. The guiding fixed bracket 32 is in the shape of a door as a whole, and a through hole is provided at its top. A through hole is also provided inside the guiding sleeve bracket 33, and the guiding sleeve bracket 33 is installed at the through hole at the top of the guiding fixed bracket 32. Both ends of the bottom of the guiding fixed bracket 32 are fixedly installed at the top of the frame 10 by bolts.

[0058] The cab guiding device 7 includes a guide pin bracket 36 and a guide pin shaft 37.

[0060] Through the guide pin shaft 37 and the through hole provided at the top of the guiding fixed bracket 32, the cab fairing 14 can be quickly positioned when installing the cab fairing 14, thereby improving the working efficiency of installing the cab fairing 14.

[0061] Optionally, through holes can also be provided on the side of the guiding fixed bracket 32, and elastic members with elasticity are transversely provided at the bottom of the cab fairing 14. When installing the cab fairing 14, press the elastic member at the bottom of the cab fairing 14 into the through holes on the side of the guiding fixed bracket 32.

[0062] In some embodiments, at least two frame guiding devices 6 are provided at the top end of the frame 10, at least two cab guiding devices 7 are connected to the bottom of the cab fairing 14, and at least two frame guiding devices 6 and at least two cab guiding devices 7 are inserted into each other in a one-to-one correspondence.

[0063] Specifically, two front frame guiding devices 23 are provided at the top end of the front frame cross member 11 of the frame, and one right rear frame guiding device 24 and one left rear frame guiding device 22 are respectively provided on the right frame longitudinal beam 13 and the left frame longitudinal beam 12 of the frame.

[0065] By arranging the frame guide device 6 and the cab guide device 7 in various directions, the positioning speed of the cab guide cabin 14 can be increased, and the work efficiency of installing the cab guide cabin 14 can be further improved. At the same time, the accuracy of the position of the cab guide cabin 14 when installing the cab guide cabin 14 can be improved.

[0066] Optionally, the frame guide device 6 and the cab guide device 7 may be arranged or disposed in other ways.

[0067] In some embodiments, see Figure 7 A suspension assembly is installed on the longitudinal outer side of the frame 10 , the top of the suspension assembly is connected to the hydraulic lock 21 , and a buffer 20 is provided at the connection between the suspension assembly and the hydraulic lock 21 .

The suspension bracket 19 is fixedly installed on the frame 10 by bolts and nuts. The buffer 20 is fixedly installed on the top of the suspension bracket 19 by bolts and nuts. The suspension hinged fixed bracket 27 is arranged on the inner side of the bottom of the hydraulic lock 21, and a groove is arranged inside the suspension hinged fixed bracket 27. The two support sleeves 28 are respectively arranged at both ends of the groove of the suspension hinged fixed bracket 27. One end of the bolt passes through the hydraulic lock 21, the suspension hinged fixed bracket 27 and the support sleeve 28 in turn in the horizontal direction, and is fixedly connected by a nut. The hydraulic lock 21 and the suspension hinged fixed bracket 27 pass through the suspension hinged fixed bracket 27, the buffer 20, the suspension bracket 19 and the gasket 26 in the longitudinal direction by bolts, and are finally connected to the suspension bracket 19 by a nut.

[0069] Since a buffer 20 is provided between the hydraulic lock 21 and the suspension assembly, and the buffer 20 has a certain plastic deformation capacity, when the cab deflector cabin 14 is vibrated, the buffer 20 can achieve a shock-absorbing effect, reducing the amplitude of the up and down bouncing of the cab deflector cabin 14, thereby increasing the service life of the cab.

[0070] Two buffers 20 are provided at the connection between the suspension assembly device and the hydraulic lock 21 to improve the shock-absorbing effect on the cab deflector cabin 14. Optionally, one or more buffers 20 may also be provided.
