They have the functions of excavating and cutting soil, transporting soil and ballast, assembling tunnel lining, measuring and guiding deviation correction, etc., and are highly reliable. The advance drill is an important part of the shield machine. When the shield machine advances forward, it encounters complex formations such as cavities, water bodies, rock fracture zones or rock burst formations. The advance drill can conduct advance drilling to explore the geological conditions ahead and determine whether there are geological disasters. If there are disasters, the advance drill will conduct advance grouting and carry out geological reinforcement treatment, and the shield machine will continue to advance the tunnel.

[0026] The embodiments of the present disclosure aim to solve the problems that when the existing shield machine is tunneling, the advanced drill is generally placed outside the tunnel. When the advanced drill is used, it is transported from outside the tunnel to the installation position inside the tunnel for installation. The space inside the tunnel is narrow, the transportation distance is long, the installation difficulty is large, and it takes a long time. In view of this, the embodiments of the present disclosure propose a shield machine advanced drill device. By adopting a new shield machine advanced drill device, when the shield machine is tunneling, the advanced drill is fixed on the connecting bridge by the fixing block of the drill fixing support frame, and when the advanced drill is used, the advanced drill is transported to the working position, solving the problems of long transportation distance and large installation difficulty of the advanced drill, with higher safety and reliability, and effectively improving the working efficiency of the advanced drill.

[0027] As Figures 1 to 6 shown, a shield machine advanced drill device includes a support device 1 and an advanced drill 2. The support device 1 is installed on the shield machine. The support device 1 is used to fix the advanced drill 2 on the connecting bridge by the fixing block 132 of the drill fixing support frame 13. When the advanced drill 2 is used, the advanced drill 2 is transported to the working position for work. The advanced drill 2 is installed on the support device 1. The advanced drill 2 is used to move on the support device 1 through its bottom wheels 21, so as to realize the position conversion during work and standby.

[0028] By adopting the above support device 1 and advanced drill 2, when the shield machine is tunneling, the advanced drill 2 is fixed on the connecting bridge by the fixing block 132 of the drill fixing support frame 13. When the advanced drill 2 is used, the advanced drill 2 is transported to the working position, solving the problems of long transportation distance and large installation difficulty of the advanced drill 2, with higher safety and reliability, and effectively improving the working efficiency of the advanced drill 2. After the advanced drill 2 finishes working, the advanced drill 2 retreats to be fixed on the drill fixing support frame 13, and the drill working support frame 11 and the detachable connecting track can be removed, which not only does not affect the normal tunneling of the shield machine, but also makes the working efficiency of the advanced drill 2 higher.

[0029] As Figures 1 to 3As shown in the figure, the support device 1 includes a drilling rig working support frame 11, a detachable track 12, and a drilling rig fixed support frame 13. The drilling rig working support frame 11 is fixed on the shield machine. One end of the drilling rig working support frame 11 is equipped with the detachable track 12, and one end of the detachable track 12 is equipped with the drilling rig fixed support frame 13. The detachable connection track is installed before the advanced drilling rig 2 works. One end is connected to the track of the drilling rig working support frame 11, and the other end is connected to the track of the drilling rig fixed support frame 13, serving as the track for the advanced drilling rig 2 to be transported between the drilling rig working support frame 11 and the drilling rig fixed support frame 13. After the advanced drilling rig 2 completes the work and returns to the drilling rig fixed support frame 13 and is fixed, it is removed.

[0030] Through the design of the support device 1, when the advanced drilling rig 2 is not working, the advanced drilling rig 2 is fixed on the drilling rig fixed support frame 13, and the support device 1 can effectively support the advanced drilling rig 2. When the advanced drilling rig 2 is working, the drilling rig working support frame 11 and the detachable connection track are installed, the fixing block 132 on the drilling rig fixed support frame 13 is opened, and the advanced drilling rig 2 is transported from the drilling rig fixed support frame 13 along the track to the drilling rig working support frame 11 by using the traction device, and the advanced drilling rig 2 is connected to the drilling rig working support frame 11 through the pin shaft 24.

[0031] Therefore, through the above support device 1, when the shield machine is tunneling, the advanced drilling rig 2 is fixed on the connecting bridge by using the fixing block 132 of the drilling rig fixed support frame 13. When using the advanced drill, the advanced drilling rig 2 is transported to the working position again, solving the problems of long transportation distance and large installation difficulty of the advanced drilling rig 2, with higher safety and reliability, and effectively improving the working efficiency of the advanced drilling rig 2.

[0032] As Figure 2 shown in the figure, the drilling rig working support frame 11 is a frame structure, with working tracks 111 for walking on both sides, and the working tracks 111 are connected to the detachable connection track; there are tracks for walking on both sides of the drilling rig working support frame 11, the tracks are connected to the detachable connection track, and the tracks are of a sharp-corner structure to prevent movement deviation.

[0033] As Figure 3 shown in the figure, the drilling rig fixed support frame 13 is a frame structure, with a fixed track 131 on the upper part connected to the detachable connection track, and fixing blocks 132 are arranged on both sides at the same time. The fixing blocks 132 can fix the advanced drilling rig 2; when the advanced drilling rig 2 is not working, the fixing blocks 132 fix the advanced drilling rig 2 on the drilling rig fixed support frame 13 to prevent the advanced drilling rig 2 from moving during the tunneling of the shield machine; by adopting the above drilling rig fixed support frame 13, the advanced drilling rig 2 can be retracted and removed after being fixed on the drilling rig fixed support frame 13 when it is not working.

[0034] As Figure 5 and Figure 6As shown in the figure, wheels 21 are provided on both sides of the lower part of the advanced drill 2, a front arm 22 and a rear arm 23 are provided in the middle of the lower part, and a pin shaft 24 and a shear pin 25 are provided at the bottom. When the front arm 22 and the rear arm 23 move the advanced drill 2 onto the drill working support frame 11, they are connected to the frame of the drill working support frame 11 through the pin shaft 24 to adjust the axial working angle of the advanced drill 2 and lock it with the shear pin 25.

[0035] The overall working process is as follows: When the shield machine advances forward, the advanced drill 2 does not work and is fixed on the drill fixed support frame 13. When the advanced drill 2 needs to work, the shield machine stops advancing, the drill working support frame 11 and the detachable connecting track are installed, the fixing block 132 on the drill fixed support frame 13 is opened, and the advanced drill 2 is transported from the drill fixed support frame 13 to the drill working support frame 11 along the track by using the traction device. The advanced drill 2 is connected to the drill working support frame 11 through the pin shaft 24. The traction device adjusts the axial angle of the advanced drill 2, and the segment erector rotates to adjust the radial angle. After the angles are adjusted, the shear pin 25 is locked, and the advanced drill 2 starts to work. After the advanced drill 2 finishes working, it is transported back to the drill fixed support frame 13 by the traction device and fixed on the drill fixed support frame 13. The drill working support frame 11 and the detachable connecting track are removed, and the shield machine can normally advance forward. This structure solves the disadvantages of small installation space and difficult installation of the advanced drill 2, and long installation time, and improves the working efficiency of the advanced drill 2.
