Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped pipes, in particular to a special-shaped pipe for a cab column of a skid loader. Background Art

[0002] Existing regulations require that the cab frame of construction machinery has sufficient strength and rigidity, and that it does not suffer overall damage or excessive deformation when the construction machinery rolls over, thereby ensuring the personal safety of the driver. The cab frame of construction machinery is welded from pipes of various specifications. In order to improve the load-bearing capacity of the cab frame and avoid excessive deformation, the pipes used should have sufficient bending resistance.

[0003] In the prior art, the cross-sections of the pipes commonly used are relatively regular square or circular pipes.

[0004] The above-mentioned prior art has the following defects: the existing standard square tube or round tube has a single shape, so that the space of the cab cannot be fully utilized, and the mechanical properties such as bending resistance and torsion resistance are not strong. Utility Model Content

[0005] In view of the above-mentioned defects, the utility model provides a special-shaped pipe for a cab column of a skid loader to solve the problem that the cab space in the above-mentioned background technology is not fully utilized and the mechanical properties such as bending resistance and torsion resistance are not strong.

[0006] The utility model is realized by using the following technical scheme: a special-shaped tube of a column of a cab of a skid loader, comprising a first vertical tube surface, the first vertical tube surface is bent 90° clockwise and extended to form a first transverse tube surface, the first transverse tube surface is bent 90° clockwise and extended to form a second vertical tube surface, the second vertical tube surface is bent 90° counterclockwise and extended to form a second transverse tube surface, the second transverse tube surface is bent 90° clockwise and extended to form a third vertical tube surface, the third vertical tube surface is bent 75° clockwise and extended to form a first inclined tube surface, the first inclined tube surface is bent in an "S" shape and extended to form a second inclined tube surface, and the second inclined tube surface is bent 75° clockwise and fixedly connected to the first vertical tube surface.

[0007] Furthermore, the "S"-shaped bending part includes a sixth arc tube surface and a seventh arc tube surface, and the central angles of the sixth arc tube surface and the seventh arc tube surface are both 90° and the radii are both 4 mm.

[0008] Furthermore, the distance between the first inclined tube surface and the second inclined tube surface is 10 mm.

[0009] Furthermore, a first arc tube surface is provided between the first vertical tube surface and the first transverse tube surface, a second arc tube surface is provided between the first transverse tube surface and the second vertical tube surface, a third arc tube surface is provided between the second vertical tube surface and the second transverse tube surface, and a fourth arc tube surface is provided between the second transverse tube surface and the third vertical tube surface.

[0010] Furthermore, the radius of the first arc tube surface and the second arc tube surface are both 5 mm, the radius of the third arc tube surface is 8 mm, and the radius of the fourth arc tube surface is 6 mm.

[0011] Furthermore, the distance between the first vertical tube surface and the third vertical tube surface is 52 mm.

[0012] Furthermore, the distance between the first vertical tube surface and the second vertical tube surface is 33 mm.

[0013] The utility model provides a special-shaped tube for a cab column of a skid loader, which is different from the prior art in that the utility model changes a traditional steel tube with a square cross-section or a circular cross-section into a steel tube with a special-shaped cross-section, so that the steel tube can better fit the cab, thereby increasing the utilization rate of the cab space. Compared with traditional steel tubes, the special-shaped steel tube has stronger bending and torque resistance, thereby making the cab more solid.
