Description

Technical Field

[0001] This utility model belongs to the field of mast technology, and in particular relates to a novel mast. Background Technology

[0002] The mast is an essential support component on the drilling rig. The reaction force caused by the torque applied to the front end by the power head acts on the guide rail of the mast, so that the mast is subjected to the torque transmitted by the guide rail. When the torque on the outer side is applied to the guide rails on both sides, the torque is transmitted to the vertical plate through the guide rail, which causes the contact part between the vertical plate and the guide rail to be subjected to large deformation, which can easily cause the weld between the guide rail and the vertical plate to crack.

[0003] In existing technologies, masts are often constructed using I-shaped double-layer partitions or concave bending plates. I-shaped double-layer partitions provide good internal support, but consume more material overall, and the mast's center of gravity shifts forward, which is detrimental to the overall stability of the machine. Concave bending plate structures lack support for the lower end of the guide rail, and the weld where the lower end of the guide rail contacts the vertical plate is still at risk of cracking when subjected to torque.
