[0002] During the construction of a mine shaft, most construction equipment is suspended by a overhead sheave and a wire rope. At the same time, as the construction of the working face continues to advance deeper, it is necessary to lower the equipment and transport personnel by lifting the suspended wire rope to meet the needs of continuous downward construction.

[0003] The main function of the well drilling derrick arranged on the ground is to hang the wire rope to bear all the construction loads. With the continuous increase in the diameter and depth of the wellbore in recent years, especially the construction of ultra-deep wellbore (over 2000m), the weight carried by the construction equipment and wire rope is getting bigger and bigger. At the same time, there is a situation of adjusting the suspension position during the operation. This not only requires the ground well drilling derrick to have the ability to bear a larger load, but also requires the ability to adjust the position of the sheave. The existing well drilling derrick has limited bearing capacity, and at the same time, its sheave suspension position cannot be adjusted. For this reason, it is urgent to provide a derrick with high bearing strength and flexible and adjustable sheave suspension position. Summary of the invention

The two adjacent oblique angled columns are arranged in an eight-shaped pattern, so that the overall outer contour of the derrick is a frustum-shaped structure, which is conducive to ensuring the overall bearing strength. Between the two adjacent oblique angled columns, three layers of combined rods, namely, an M-shaped assembly, a W-shaped assembly and an eight-shaped assembly, are arranged from top to bottom, and are connected in sequence through an upper transverse support and a lower transverse support to form a rod system assembly. In this way, the overall bearing strength can be effectively increased by the rod system assembly located in the middle and the two oblique angled columns located on the outside, thereby effectively bearing the load transmitted from the sheave platform.

[0014] The overall structure of the derrick is reasonable, with high bearing strength and good flexibility. It can not only meet the construction needs of suspending super-large loads during the construction of ultra-deep vertical shafts, but also the position of the sheave hanging on its sheave platform can be adjusted according to different working conditions, thereby meeting the use requirements of different working conditions.

Between the two adjacent oblique angled columns, three layers of combined rods, namely, an M-shaped assembly, a W-shaped assembly and an eight-shaped assembly, are arranged from top to bottom, and are connected in sequence through an upper transverse support and a lower transverse support to form a rod system assembly.
