A crawler full hydraulic tunnel drilling rig

Abstract

The invention discloses a crawler full hydraulic tunnel drilling rig, which comprises a drill bit assembly, a frame assembly, a walking assembly, a hydraulic pump assembly, an egg-shaped support assembly and an explosion-proof remote control electric box. The frame assembly includes a platform plate, a rotating motor, a drill bit Rotary oil cylinder, support frame and lifting oil cylinder, one side of the platform plate is provided with a turntable, the bottom of the support frame is provided with an annular pressure plate, the bottom of the annular pressure plate is provided with a rotating shaft, and a rotating sleeve is provided in the turntable, The supporting frame is installed on the turntable through the cooperation of the rotating shaft and the rotating sleeve, and the rotating motor is arranged at the bottom of the rotating disk and connected with one end of the rotating shaft through the driving shaft. The invention uses the left sphere group and the right sphere group in the egg-shaped support combination to control the rotation of the sphere through the front rotary motor and the rear rotary motor, rotate the sphere to the top, and control the support cylinder to make the sphere stretch out against the wall at the top of the roadway , to avoid the collapse of the wall due to vibration.

Description

technical field [0001] The invention relates to the technical field of geological machinery, in particular to a crawler full hydraulic tunnel drilling machine. Background technique [0002] Tunnel drilling rig is specially used for drilling in underground roadways (tunnels). It is mainly used for deep geological exploration, gas drainage, drainage, ventilation and other constructions in roadways (tunnels). It is divided into spiral differential feed There are two types of advance type and power head type (mechanical type and full hydraulic type), among which the full hydraulic type is more common, but the tunnel drilling rigs commonly used at present usually have the following defects: 1. The structure of the tunnel drilling rigs currently used is relatively large. When drilling in the underground tunnel, the tunnel drilling rig has a high requirement on the volume of the tunnel, which requires a separate excavation and placement site to be suitable for the installation and ...

[0002] Tunnel drilling rig is specially used for drilling in underground roadways (tunnels). It is mainly used for deep geological exploration, gas drainage, drainage, ventilation and other constructions in roadways (tunnels). It is divided into spiral differential feed There are two types of advance type and power head type (mechanical type and full hydraulic type), among which the full hydraulic type is more common, but the tunnel drilling rigs commonly used at present usually have the following defects: 1. The structure of the tunnel drilling rigs currently used is relatively large. When drilling in the underground tunnel, the tunnel drilling rig has a high requirement on the volume of the tunnel, which requires a separate excavation and placement site to be suitable for the installation and placement of the drilling rig, which greatly increases the labor load of the drilling construction. 2. Underground There will be a large amount of drilling material during the drilling construction of the roadway, and the drilling material will be piled up around the drilling machine. When the roadway is narrow, it is not conducive to the movement of the drilling machine. In this way, it is easy to cause hidden dangers of subsidence and safety accidents in the underground roadway of the coal mine. Therefore, the present invention provides a crawler full hydraulic tunnel drilling rig
