Description

Technical Field

[0001] The invention relates to the technical field of hydraulic drilling rigs, and in particular to a hydraulic drilling rig mounted on a tunnel boring machine. Background Art

[0002] The hydraulic drilling rig on the tunnel boring machine is usually used to drill holes in the rock walls of coal mining tunnels to facilitate the installation of support equipment and other equipment at a later time, or to drill into the ground where needed. The drilling depth of the ground is usually large. Generally, the initial drill rod is drilled first. After drilling, the drill rod and the motor are separated and connected to another drill rod, and the other drill rod is connected to the motor for drilling. By continuously splicing multiple drill rods, deep drilling work can be carried out on the ground. For tunnel drilling, thick drill rods or the same thin drill rods as for ground drilling can be used for drilling work as needed.

[0003] However, conventional airborne hydraulic drilling rigs usually connect one end of the drill rod to the motor output shaft, and then perform drilling work at the other end, and do not limit the drill rod that has not been drilled into the rock. This can easily cause the drill rod outside to shake, affecting its service life and the drilling accuracy. When the ground drilling work is completed and the drill rod that has been drilled needs to be pulled out, the drill rod connected to the motor needs to be pulled out, so that several drill rods inside the borehole are pulled up as a whole. After being pulled up to a certain height, the drill rod connected to the motor is separated and then removed. The motor moves down and connects to the next drill rod, and then the drill rod is pulled out and removed. The above operation is repeated until the drill rod is taken out. However, the drill rod is not limited during the process, and it is easy for the drill rod still in the borehole to fall off due to the loss of connection between the drill rod inside the borehole and the removed drill rod when the drill rod is separated.

Three springs 21 are provided between the fixed plate 14 and the triangular block 16.

[0020] The limiting structure 11 and limiting component 1 cooperate with each other to limit the size of the drill rod and provide auxiliary positioning for the drill rod, so that the drill rod can be stabilized and avoid large shaking during drilling. At the same time, the setting of the ball 20 ensures that the ball 20 will not generate large resistance friction to the rotation and up and down movement of the drill rod.

At the same time, in conjunction with the limiting structure 11, it can better provide stable working conditions for the drilling work of the drill rod, and avoid the storage rack 5 from shaking significantly when the drill rod is drilling, affecting the accuracy.

Before use, the hydraulic drill rig is placed in a required location to enable it to reach working conditions. According to the use requirements, the hydraulic drill rig can be used in two usage scenarios. In addition, Figure 1 , Fig.12 as well as Fig.13 The initial state diagram of drilling into the ground for the use scenario 1; Use scenario 1: When deep drilling is required, Figure 1 In the initial state, one end of the initial drill rod is fixedly connected to the output shaft of the motor 27, and then the motor 27 is started to rotate the initial drill rod, and the multi-stage electric telescopic rod 19 is started to make the storage plate 6 slide toward the ground on the inner side of the storage rack 5. During the process, one end of the initial drill rod passes through the hollow plate 10 and drills into the ground to perform drilling work. The electric push rod 28 is started to act on the fixed frame 29 to move the three fixed rods 30 in the opposite direction of the ground. The fixed rod 30 moves upward and acts on the triangular block 16 to move toward the fixed plate 14. The triangular block 16 acts on the sleeve 19 and the ball 20 through the movable rod 15 to move synchronously until the ball 20 contacts the surface of the initial drill rod and stops. At this time, several balls 20 limit and support the drill rod to prevent the drill rod from shaking significantly and affecting the accuracy. When the storage plate 6 moves down to the predetermined position, most of the initial drill rod is drilled into the ground, and the motor 2 7 is stopped at this time, and the electric push rod 2 32 is started to act on the connecting plate 33 to move the fixed frame 2 34 toward the ground, and the fixed frame 2 34 acts on the fixed frame 35 and the movable roller 36 to move synchronously, and the movable roller 36 acts on the triangular block 24 to move toward the fixed plate 22, and the triangular block 24 acts on the limit plate 25 through the movable rod 23 to move synchronously until the limit plate 25 contacts the surface of the initial drill rod and stops, at which time the limit plate 25 clamps and fixes the initial drill rod, and then the initial drill rod is The rod and the output shaft of the motor 2 7 are separated, and the multi-stage electric telescopic rod 1 9 is started to make the motor 2 7 and the storage plate 6 return to the initial position, and the two ends of the next drill rod are respectively connected to the output shaft of the motor 2 7 and one end of the initial drill rod, and then the movable roller 36 is returned to the initial position by the electric push rod 2 32. Under the action of the spring 26, the limit plate 25 rebounds to the initial position to release the clamping restriction on the initial drill rod, and the motor 2 7 and the multi-stage electric telescopic rod 1 9 are started to continue the drilling work with the initial drill rod and the next drill rod just connected. The above operation can be repeated to increase the number of drill rods according to the drilling depth requirements; After the ground drilling is completed, the motor 27 is stopped from rotating, and the motor 27 is pulled back to the initial position by the multi-stage electric telescopic rod 19. At this time, the several drill rods drilled into the ground are all pulled up, and the corresponding drill rods are clamped and fixed by the electric push rod 232, and the drill rod connected to the motor 27 is taken out, and then the motor 27 is moved down to the next drill rod by the multi-stage electric telescopic rod 19 and connected, and the fixing frame 234 is moved to the initial position by the electric push rod 232. Under the action of the spring 26, the limit plate 25 releases the restriction on the drill rod, and then the motor 27 is pulled back to the initial position by the multi-stage electric telescopic rod 19, and then the limit plate 25 is clamped by the electric push rod 232, and then the drill rod connected to the motor 27 is taken out, and the above operation is repeated to take out the drill rod; When the drilling work is finished and the drill rod is taken out, the threaded rod 52 is rotated to make the block 53 move toward the fixed block 2 51 until the block 53 releases the restriction on the upper side of the limit slot plate 50 and stops. The motor 1 4 is started to make the movable frame 3 rotate 90 degrees with the storage rack 5 in the opposite direction to the ground and then stop. At this time, the storage rack 5 is parallel to the ground. The multi-stage electric telescopic rod 2 38 is started to act on the baffle 2 39. The baffle 2 39 moves the storage rack 5 in the opposite direction to the support plate 2 to a predetermined position and then stops. The motor 3 43 is started to make the fixed sleeve 44 rotate 90 degrees with the multi-stage electric telescopic rod 3 45 in the direction of the ground and then stop. Start the multi-stage electric telescopic rod 3 45 to move one end toward the top of the machine body 1 until it contacts the top of the machine body 1 and stops. Then start the motor 47 to act on the gear roller 48 to rotate. The gear roller 48 and the serrated plate 49 are meshed to make the slider 41 slide outside the slide plate 40 toward the direction of the motor 2 7 until one end of the multi-stage electric telescopic rod 3 45 is stuck in the limit groove plate 50 and stops. Rotate the threaded rod 52 to make the block 53 move to limit one end of the multi-stage electric telescopic rod 3 45 and stop.

Use scenario 2: When drilling into the rock wall of a tunnel is required, Figure 1 In the initial state, the motor 1 4 is started to make the movable frame 3 rotate 90 degrees with the storage rack 5 in the opposite direction to the ground and then stop. At this time, the storage rack 5 is parallel to the ground. The motor 3 43 is started to make the fixing sleeve 44 rotate 90 degrees with the multi-stage electric telescopic rod 3 45 in the direction of the ground and then stop. The multi-stage electric telescopic rod 3 45 is started to make one end of the storage rack 5 move toward the ground until it contacts the ground and stops. At this time, the two ends of the storage rack 5 are respectively supported by the multi-stage electric telescopic rod 3 45 and the support plate 2 to avoid the storage rack 5 with one end of the hollow plate 10 lacking support force, which causes a large shaking during drilling and affects the accuracy. At this time, the drill rod is installed on the output shaft of the motor 2 7 and the rock wall can be drilled according to the same operating principle as the use scenario 1. After the drilling is completed, the drill rod is taken out and the storage of the storage rack 5 is consistent with the operation principle of the use scenario 1. In addition, drill rods of different thicknesses can be installed as needed for drilling work. At the same time, the movable frame 3 and the fixed sleeve 44 are not limited to rotating ninety degrees. The movable frame 3 and the fixed sleeve 44 can be adjusted by motor 1 4 and motor 3 43 respectively according to the drilling angle.
