[0035] As Figures 1 to 3 shown is a retractable cab roof device of this embodiment, which mainly includes a roof and a support column. Among them, the roof is composed of an outer frame 1, a strengthening part 2, and a roof panel 3. The outer frame 1 is an overall annular frame structure, the strengthening part 2 is in a radial shape, the strengthening part 2 is arranged inside the outer frame 1, and the radial ends of the strengthening part 2 are fixedly connected to the inner ring contour of the outer frame 1 by welding. The roof panel 3 covers the tops of the outer frame 1 and the strengthening part 2 by welding and / or bolt connection. The first end of the support column is connected to the bottom of the outer frame 1 and / or the strengthening part 2, the second end of the support column is provided with a connection mechanism capable of cooperating with the cab, and the support column is a telescopic column structure.

[0036] Specifically in this embodiment, the outer frame 1 is an overall rectangular structure, the strengthening part 2 is an overall cross-radial structure, and the four radial ends of the strengthening part 2 are respectively connected to the middle regions of the four sides of the outer frame 1. By making the strengthening part 2 symmetrically distributed inside the outer frame 1 and jointly forming the skeleton of the roof with the outer frame 1, it can not only make the force on the roof more uniform, enhance the compressive resistance, but also effectively reduce the weight of the roof and save costs.

[0037] In the specific application process, the outer frame 1 and the strengthening part 2 can also adopt other structural forms. For example, the outer frame 1 can be set as a circular frame structure or a hexagonal frame structure, etc., and the strengthening part 2 can be set as a cross-radial shape, etc.

[0038] As a preferred embodiment, the ceiling further includes a mounting plate 4. The mounting plate 4 is fixedly connected to the bottom of the first end of the outer frame 1 and / or the bottom of the first end of the reinforcing part 2 by welding and / or bolting. The first end of the support column is connected to the mounting plate 4. Specifically, in this embodiment, the mounting plate 4 is connected and fixed to the bottom of the first end of the outer frame 1 and the bottom of the first end of the reinforcing part 2 by welding and / or bolting, thereby ensuring the stability of the connection between the mounting plate 4 and the ceiling.

[0039] In this embodiment, the mounting plate 4 is eccentrically arranged with respect to the ceiling, so that the support column connected to the mounting plate 4 is also eccentric with respect to the ceiling. Therefore, during the process of assembling the ceiling in the cab, the radiation center of the reinforcing part 2 can be positioned directly above the driver's seat, thus maximizing the safety of the driver.

[0040] Further preferably, the mounting plate 4 has a T-shaped structure, including a horizontal first end and a vertical second end. The first end of the mounting plate 4 and the first end of the shed plate 3 both extend to a certain extent beyond the outer contour of the outer frame 1, and at least one reinforcing rib plate 5 is welded between the extended parts of the first end of the mounting plate 4 and the extended part of the first end of the shed plate 3. For example, in this embodiment, the number of the reinforcing rib plates 5 is four, thereby further improving the overall stability of the ceiling. The second end of the mounting plate 4 extends to more than 1 / 2 of the reinforcing part 2 to disperse stress, which can strengthen the stability of the ceiling, so that when the second end of the outer frame 1 is hit by a heavy object, the ceiling is not easily broken from the middle.

[0041] Further preferably, a plurality of rectangular through holes are provided on the mounting plate 4 for plug welding to enhance the connection strength between the mounting plate 4 and the bottom of the first end of the outer frame 1 and / or the bottom of the first end of the reinforcing part 2.

[0042] It should be noted that in the specific application process, the mounting plate 4 may not be provided separately, that is, the support column can be directly connected to the bottom of the first end of the outer frame 1 and / or the bottom of the first end of the reinforcing part 2.

[0043] In the specific implementation process, the outer frame 1 and the reinforcing part 2 can be spliced and formed by a plurality of hollow tubes and / or bent plates through welding and / or bolting, thereby greatly reducing the weight of the ceiling and lowering the cost.

[0044] Reference Figure 4, the support column includes a first sleeve 6, a second sleeve 7 and a driving oil cylinder 8. The connecting mechanism is arranged at the first end of the first sleeve 6. For example, the first end of the first sleeve 6 is directly welded or bolted to the cab. The second end of the second sleeve 7 is fixedly connected to the mounting plate 4 by welding and / or bolting. The second end of the first sleeve 6 is sleeved on the first end of the second sleeve 7, and the first sleeve 6 and the second sleeve 7 are in sliding fit. By the relative sliding of the first sleeve 6 and the second sleeve 7, the length of the support column can be changed, and thus the telescoping of the support column can be realized. The driving oil cylinder 8 is arranged inside the first sleeve 6 and the second sleeve 7, and the first end of the driving oil cylinder 8 is connected to the cab or the first sleeve 6, and the second end of the driving oil cylinder 8 is connected to the mounting plate 4 or the second sleeve 7. For example, in this embodiment, an ear seat 9 is welded to the bottom of the mounting plate 4, and the second end of the driving oil cylinder 8 is connected to the mounting plate 4 through a pin shaft cooperating with the ear seat 9. At the same time, a bushing is welded on the inner wall of the first end of the first sleeve 6 or on the cab, and the first end of the driving oil cylinder 8 is connected to the first sleeve 6 through a pin shaft cooperating with the bushing. Among them, a through hole 601 is provided on the side wall of the first end of the first sleeve 6 for connecting the decompression pipeline of the driving oil cylinder 8.

[0045] As a preferred embodiment, a bent strengthening plate 10 is sleeved on the second end of the first sleeve 6, that is, the second end of the first sleeve 6 is thickened, and the strength of the first sleeve 6 and the second sleeve 7 in the horizontal direction during relative movement.

[0046] It should be noted that in the specific application process, it is not limited to using the illustrated support column, and other structural members with telescoping functions can also be used as the support column, such as hydraulic scissors.

[0047] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
