Beam structure and drilling rig

Abstract

The invention discloses a cross-beam structure and a drilling machine, and relates to the field of engineering machinery. The cross-beam structure and the drilling machine are used for optimizing the cross-beam structure, and on the premise that the bearing capacity of the cross-beam structure is ensured, the lightweight of the cross-beam structure is achieved. The cross-beam structure is used for being installed at an external arm of the drilling machine and comprises an installation part and a stress part, the installation part is constructed to protrude towards the direction which is far away from the external arm of the drilling machine, and the stress part is installed on the protruding surface of the installation part. The cross-beam structure provided by the technical scheme comprises the protruding installation part and the stress part arranged on the protruding surface of the installation part, compared with an existing cross-beam structure, under the condition that the bearing capacities are the same, the cross-beam structure provided by the embodiment is lowest in weight, and the lightweight of the cross-beam structure can be achieved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a beam structure and a drilling rig. Background technique [0002] Due to its strong mobility and convenient transition, vehicle-mounted deep well drilling rigs have become more and more widely used in the development of natural gas, coalbed methane, shale gas and other energy sources in recent years. The drilling tower structure of the vehicle-mounted deep well drilling rig is used for tension, compression and torsional loads, and is subjected to complex forces. The upper beam structure of the outer arm is an important component of the drilling tower structure and is the direct carrier for the lifting and lowering of the drilling tower. Since the upper beam of the outer arm is not located in the center of the outer arm after being loaded when the drilling tower is lifted and lowered, it will bear the bending moment. During drilling operations, the drilling tower is subjecte...

AI Technical Summary

Problems solved by technology

[0004] The inventors have found that at least the following problems exist in the prior art: due to the unreasonable design of the upper beam structure of the outer arm of the existing vehicle-mounted deep well drilling rig, the rigidity and strength of the upper beam of the outer arm are relatively weak, causing the vehicle-mounted deep well drilling rig to twist during actual operation. The deformation is large, and the weld seam is easy to tear, which affects the stability of the whole vehicle; in order to increase its rigidity and strength, the method of increasing the size and thickness of the plate is used in the prior art, but the weight of the upper beam structure is large after the structural size is strengthened, which is not conducive to the exterior Lightweight design of beam structure on arm
