Problems solved by technology

[0004] Wherein, the main body 107 of the drilling rig remains stable by its own gravity and the gravity of the base 101. However, due to the high-speed rotation of the main body 107 of the drilling rig, a large radial centrifugal force is generated, and when the centrifugal force is too large, the base 101 will produce radial deflection; There is a large axial force when pulling out, and when the axial force is too large, the base 101 will produce axial displacement, which will cause the main engine of the drilling rig to fail to work normally

Abstract

The invention discloses an underground drill rig and a supporting device thereof. The supporting device comprises a base, a stand column, a driving device, a connection component and a column cap, the stand column is arranged on the base, the driving device is arranged at the top end of the stand column, the connection component is driven by the driving device to perform extension and retraction movement along the axial direction of the stand column, and the column cap is spherically hinged at the top end of the connection component. By means of the supporting device of the underground drill rig, stability of the underground drill rig during operation can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a tunnel drilling rig and a supporting device thereof. Background technique [0002] With the rapid development of economic construction, significant progress has been made in the field of construction machinery technology. Among them, the drilling rig is a mechanical device that drives the drilling tool to drill in any direction during geological exploration to obtain physical geological data. The main function of the drilling rig is to break the rock at the bottom of the drilling hole, and to lower or raise the drilling tool in the hole to prove the underground geology and mineral resources. According to the implementation of on-site drilling rigs, it can be divided into: surface drilling rigs, tunnel drilling rigs, submerged drilling rigs, etc. Among them, the tunnel drilling rig is mainly based on the full hydraulic power head type, and generally consists of three part...
