[0002] like Figure 1 As shown, the open cab frame structure is usually composed of an existing roof (11) and an existing bracket (12), which is installed on the excavator cab floor frame and fixed after installation. It has functions such as sunshade and rain protection, handrails, driver protection, instrument installation, and work lights, and is widely used in excavators.

[0003] The shortcomings of existing technology: Normally, the cab frame cannot be extended or folded. When transporting the whole machine, the cab roof occupies a lot of height space. In situations with special transport size requirements and the need for rapid use after delivery, the cab frame and related wiring harnesses and instruments need to be removed to transport the whole machine. This is troublesome and cannot be achieved in such special applications. Utility Model Content

[0004] The purpose of this utility model is to provide a cab frame structure and engineering machinery to solve the technical problem that the cab frame in the prior art is fixed and cannot be folded.

[0005] To achieve the above objectives, the present invention provides a cab frame structure, including a roof, a support frame below the roof, a first bracket between one end of the roof and one end of the support frame, and a second bracket between the other end of the roof and the other end of the support frame. The top end of the first bracket is connected to one end of the roof, and the bottom end of the first bracket is hinged to one end of the support frame. The top end of the second bracket is detachably connected to the other end of the roof, and the bottom end of the second bracket is hinged to the other end of the support frame. The roof can be flipped to the other side of the support frame. A detachable fixing structure is also provided between the roof and the support frame, which can achieve relative fixation between the roof and the support frame.

[0006] Furthermore, the top end of the first bracket is fixedly connected to one end of the canopy.

[0007] Furthermore, the bottom end of the first bracket is hinged to one end of the support frame by a pin and fixedly connected by the detachable fixing structure.

[0008] Furthermore, the top end of the second bracket is detachably connected to the other end of the canopy via a wing bolt.

[0009] Furthermore, the bottom end of the second bracket is hinged to the other end of the support frame by a pin and fixedly connected by the detachable fixing structure.

[0010] Furthermore, the detachable fixing structure is a wing bolt.

[0011] Furthermore, the other end of the support frame is provided with a first connecting hole, and the second bracket is provided with a second connecting hole. The first connecting hole and the second connecting hole can be connected by a wing bolt.

[0012] Furthermore, the other side of the support frame is provided with a third connecting hole and a fifth connecting hole, and the other side of the canopy is provided with a fourth connecting hole and a sixth connecting hole. The third connecting hole and the fourth connecting hole can be connected by a wing bolt, and the fifth connecting hole and the sixth connecting hole can be connected by a wing bolt.

[0013] Furthermore, the number of support frames includes two, with the two support frames located at the lower front and lower rear of the canopy respectively, and the canopy can be flipped to the left side between the two support frames; the first bracket and the second bracket are rod-shaped, and the top ends of the two first brackets are connected to form a U-shaped rod.

[0014] This utility model also provides an engineering machinery, including an engineering machinery body and a cab frame structure as described in any of the above technical solutions, wherein the cab frame structure is disposed on the engineering machinery body.

[0015] In summary, the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonable. (1) A support frame is provided below the canopy, a first bracket is provided between one end of the canopy and one end of the support frame, and a second bracket is provided between the other end of the canopy and the other end of the support frame; thus, the canopy can be supported above the support frame by using the first bracket and the second bracket. (2) The top of the first bracket is connected to one end of the canopy, the bottom of the first bracket is hinged to one end of the support frame, the top of the second bracket is detachably connected to the other end of the canopy, and the bottom of the second bracket is hinged to the other end of the support frame, so that the canopy can be flipped to the other side of the support frame; thus, when rotation and folding are required, the top of the second bracket can be separated from the other end of the canopy, then the second bracket can be rotated 180° toward the other side of the support frame, and then the first bracket with the canopy can be tilted 90° toward the other side of the support frame, so that the canopy can be flipped to the other side of the support frame. After folding, the height of the cab can be reduced, which can meet the transportation needs of the whole machine under special working conditions. (3) A detachable fixing structure is also provided between the roof and the support frame, which can achieve relative fixation between the roof and the support frame.
