[0010] Preferably, one side of the pilot housing is detachably connected to a maintenance cover plate by bolts.

[0011] Beneficial effect: The utility model provides a detachable pilot handle and pipeline device for an engineering machinery vehicle. When disassembly is required, it is only necessary to remove the cover plate, separate the pilot handle and pipeline from the cover plate, remove the sealing plate and the fixing plate, etc., and then the pilot handle and pipeline can be removed as a whole, thereby eliminating the risk of oil leakage and causing no oil pollution. During the secondary assembly process, there is no need to reconnect the pipeline, which will not affect the accuracy of the assembly and can effectively avoid unnecessary accidents caused by unfamiliarity with hydraulic connections.

DETAILED DESCRIPTION

[0017] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0018] Example 1: Figure 1-3As shown, a detachable pilot handle and pipeline device for an engineering machinery vehicle provided by an embodiment of the utility model comprises a bottom plate 11 of a cab and a pilot box assembly, wherein the pilot box assembly comprises a pilot box body 21 and a fully connected pilot handle and pipeline 22; the fully connected pilot handle and pipeline 22, that is, the pilot handle and the pipeline are connected as a whole, and they do not need to be separated or reconnected during the disassembly process. A detachable cover plate 23 is provided at the upper end of the pilot box body 21, and the pilot handle and pipeline 22 are detachably connected to the cover plate 23. The lower end of the pilot box body 21 is An open structure is fixed on the base plate 11. The open structure means that there is no base plate at the lower end. A first sealing gasket 24 is provided between the two for sealing. The bottom surface of the base plate 11 is detachably connected to a sealing plate 25. A second sealing gasket 26 is provided between the two for sealing. The sealing plate 25 is detachably connected to a first fixing plate 27. The sealing plate 25 is provided with an opening for the first fixing plate 27 to be embedded therein. A plurality of sealing plugs 28 are distributed on the first fixing plate 27.
