Description

Technical Field

[0001] The invention relates to the field of tunnel drilling rigs, and more particularly to a crawler type tunnel drilling rig. Background Art

[0002] Drilling rigs play an important role in the mining industry as important tools for drilling holes in coal mining, tunnel excavation construction and deep-water drilling. Existing tunnel drilling rigs, especially small and medium-sized tunnel drilling rigs, have relatively fixed drilling angles, poor adaptability to the drilling environment, and mostly use manual rod connection operations. When drilling at large elevation angles or higher hole positions, manual rod connection is difficult, which seriously affects the drilling efficiency of the drilling rig. Existing tunnel drilling rigs mostly use crawler travel devices, which can be used in most complex tunnel operating environments. However, due to the limitations of their own structure, crawler drilling rigs are difficult to accurately adjust the horizontal position, especially in some tunnels with small spaces and complex support surfaces. Crawler drilling rigs are also difficult to provide stable and reliable support for drilling operations, which can easily cause the drilling rig to produce rod movement or deviated holes during the drilling process.

[0028] An operating seat 7 is fixedly disposed on one side of the operating console 6 on the upper portion of the main carrier 1 .

[0029] Embodiment 2:

[0030] Based on Example 1, the working principle of a crawler tunnel drilling rig is as follows: When a crawler tunnel drilling rig is in operation, the operator controls the drilling rig through the operating console 6, the power box 5 provides driving force for the entire drilling rig, the horizontal rotator 8 rotates horizontally, and one end of the suspension clamp 903 of the drilling support frame 9 is adjusted to the direction of the hole to be drilled. The upper support assembly 4 rises to support the tunnel roof, and the support hydraulic 304 of the lower support assembly 3 descends to support the tunnel floor, providing a stable support for the entire drilling operation. According to the specific position of the hole to be drilled, the operator controls the lifting hydraulic 103 and the rotating disk assembly 12 to adjust the drilling support frame 9 to a suitable height angle. Under the support of the suspension clamp 902, the drilling gyroscope 903 firmly clamps the drill rod for rotation, and the circulating water tail 905 is threadedly connected to the tail of the drill rod to provide circulating water for the drilling operation. At the same time, under the action of the drilling hydraulic 906, the drilling gyroscope 903 moves along the guide rail frame beam 901 toward the suspension clamp 902 according to the drilling pressure and speed of the drill rod.

[0031] Embodiment 3:

[0032] On the basis of Example 1 and Example 2, after the drill rod of a crawler tunnel drilling rig is drilled, the drilling gyrator 903 stops rotating, and the suspension clamp 902 holds the drill rod tightly, and the circulating water tail device 905 automatically reverses to loosen the threaded connection between it and the drill rod, and the distance adjustment hydraulic device 909 is actuated to push the circulating water tail device 905 to move along the guide rail frame beam 901 to the cross beam 908, and the main hydraulic device 1101 and the auxiliary hydraulic device 1102 of the mechanical arm 11 start to move to lower the main boom 1108 to a suitable position, and the I# drive motor 1103 drives the main hydraulic device 1101 to move the main hydraulic device 1108 to a suitable position. The movable straight arm 1107 rotates counterclockwise to a horizontal position, and at the same time, the II# drive motor drives the mechanical gripper 1106 to loosen the tension through the drive box 1109. The driller puts a section of drill pipe into the mechanical gripper 1106, and the II# drive motor drives the drive shaft arm 1111 through the drive box 1109 to drive the mechanical gripper 1106 to grasp the drill pipe. The mechanical gripper grasps the drill pipe, and then the I# drive motor 1103 drives the straight arm 1107 to rotate clockwise to a vertical position, and the main hydraulic valve 1101 and the auxiliary hydraulic valve 1102 start to move, so that the main boom 1108 The drill pipe rises to the original position, and the I# driving motor 1103 drives the straight arm 1107 to rotate clockwise, so that the center line of the drill pipe coincides with the center line of the holding hole on the drilling gyro 903 and the circulating water tail device 905, and the drilling hydraulics 906 and the distance adjusting hydraulics 909 are actuated to make the drilling gyro 903 and the circulating water tail device 905 move toward each other. When the two ends of the drill pipe enter the holding holes of the drilling gyro 903 and the circulating water tail device 905 respectively, the distance adjusting hydraulics 909 stop actuating, and the drilling hydraulics 906 push forward. When the end of the drill pipe contacts the top of the new drill pipe, the drilling hydraulics 906 stops actuating. 906 stops, the drilling gyroscope 903 holds the new drill pipe tightly and rotates slowly to complete the threaded connection between the new drill pipe and the drilling pipe, and then the circulating water tail device 905 automatically rotates to complete the threaded connection between its own threaded mouth and the end of the new drill pipe and stops. After completing the above movements, the drilling gyroscope 903 loosens the drill pipe and moves to the circulating water tail device 905 under the coordinated action of the drilling hydraulics 906 and the distance adjustment hydraulics 909. Thereafter, the suspended clamp 902 loosens the drill pipe, and the drilling hydraulics 906 holds the drill pipe tightly and rotates to complete the drilling operation of the next section of the drill pipe.

[0033] Embodiment 4:

[0034] On the basis of Example 1, when a crawler tunnel drilling rig needs to shift forward or backward, the operator controls the crawler walking component 2 through the operating console 6 to make the crawler tunnel drilling rig move forward or backward. When the crawler tunnel drilling rig reaches the required working position, the operator can control the lower support component 3 to start through the operating console 6. According to the ground conditions of the crawler tunnel drilling rig, the four supporting hydraulic presses 304 can be deployed simultaneously or separately, so that the main carrier frame 1 of the crawler tunnel drilling rig is in a horizontal state, providing better horizontal support for the drilling operation.

[0035] In particular, when the drilling position is too close to the edge of the tunnel and the drill bit of a crawler tunnel drilling rig cannot complete the drilling operation, the operator controls the lower support assembly 3 to adjust the horizontal displacement through the operating console 6.

[0036] The specific process is as follows: the upper support assembly 4 is folded up, the hydraulic support 304 props up the main carrier frame 1, so that the crawler walking assembly 2 is completely off the ground, and according to the horizontal displacement direction, the transverse hydraulic press 305 is actuated to cause the end cross beam 303 to drive the I# fixed plate 306 to displace in a determined horizontal direction, and then, the hydraulic support 304 is folded up to support the crawler walking assembly 2 on the ground, and the transverse hydraulic press 305 is actuated to cause the end cross beam 303 to drive the I# fixed plate 306 to displace in a direction opposite to the determined horizontal direction, and then the above actions are repeated until a crawler tunnel drilling rig completes the adjustment of its horizontal position.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and improved concepts of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
