Description

Technical Field

[0001] The utility model relates to the technical field of raise-well drilling machines, in particular to an anti-deviating automatic walking raise-well drilling machine. Background Art

[0002] Raise boring machine is a kind of efficient and safe drilling equipment. Raise boring machine mainly drives hydraulic motor through the motor of drilling machine, and hydraulic motor drives water tap, and uses hydraulic power to transmit torque to drilling tool system, thereby driving drill pipe and drill pipe to rotate. Under the action of drilling pressure, the roller cutter on pilot hole drill pipe or reaming drill pipe rolls or slides slightly along the rock working surface at the bottom of the well. At the same time, the axial tension and pressure generated by the main engine oil cylinder also act on the drill pipe, so that the roller cutter teeth have impact, extrusion and shearing effects on the rock, thereby breaking the rock. After the water and electricity conditions are met, the raise boring machine is installed on the pre-cast concrete foundation, and the hydraulic system pipelines and electrical lines of each part are connected. After operation and debugging, the drilling machine is driven to drill the guide hole from top to bottom, the pilot hole drill pipe is removed in the lower tunnel, the reaming drill pipe is connected, and the reaming drilling process from bottom to top begins. The diameter of the expanded shaft is generally 1 to 2 meters. After the pilot hole is fully expanded, the construction is completed after the drill rod is hoisted, the main engine is laid down, the working surface is cleaned, and the wellhead is protected. The raise boring machine was originally used mainly in coal mine ventilation projects. After technical improvements, it is now mainly used in the construction of vertical shafts, inclined shafts, pressure regulating shafts, ventilation shafts and drainage shafts in hydropower projects.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: an anti-deviating automatic walking raise boring machine, comprising: a raise boring machine body 1, an anti-deviating ring 2, a screw rod 3, an outer locking nut 4, an inner locking nut 5, a connecting frame 6, a connecting shaft 7, a supporting roller 8, an air suction pipe 9, an air suction cylinder 10, a dust filter 11, an air inlet 12, a filter box 13, an air suction pump 14, a filter 15, a slag discharge port 16 and a box door 17;

[0028] When using the anti-deviation self-propelled raise boring machine, if Figure 5 As shown, the operator drives the raise boring machine body 1 to the work place, and an anti-deviation ring 2 is fixedly connected to the upper right side of the raise boring machine body 1. A component to prevent the square from deviating is arranged inside the anti-deviation ring 2. When the raise boring machine body 1 is fixed to the ground, the center point of the anti-deviation ring 2 is made to coincide with the center point of the drilling well, so that the raise boring machine body 1 can be fixed;

[0029] like Figure 1 and Figure 2 After the drill pipe of the raise drilling rig body 1 is inserted into the ground and works closely, it is necessary to protect the drill pipe from deviation. The outer locking nut 4 and the inner locking nut 5 are rotated to make the inner sides of the outer locking nut 4 and the inner locking nut 5 stay away from the anti-drift ring 2. Since the screw rod 3 and the anti-drift ring 2 are threadedly connected, and the screw rod 3 is rotatably connected to the connecting frame 6, the screw rod 3 is rotated to adjust the distance from the connecting frame 6 to the center of the anti-drift ring 2 until the supporting roller 8 on the inner side of the connecting frame 6 is tightly fitted with the drill pipe, and then the outer locking nut 4 and the inner locking nut 5 are rotated to make the inner sides of the outer locking nut 4 and the inner locking nut 5 tightly fit with the side of the anti-drift ring 2. Finally, the remaining screw rods 3 are adjusted in the same way. At this time, the drill pipe will not deviate, which effectively ensures the normal operation of the equipment, reduces equipment loss, and greatly improves the working efficiency of the drilling rig.

[0030] like Figure 1 and Figure 2 When the drill rod needs to be replaced, the outer locking nut 4 and the inner locking nut 5 are rotated again to make the inner sides of the outer locking nut 4 and the inner locking nut 5 away from the anti-deviation ring 2, and the screw rod 3 is rotated to adjust the distance from the connecting frame 6 to the center of the anti-deviation ring 2 according to the radius of the drill rod, so that the distance from the connecting frame 6 to the center of the circle is slightly larger than the radius of the drill rod. After the drill rod is installed, the screw rod 3 is rotated until the support roller 8 on the inner side of the connecting frame 6 is tightly fitted with the drill rod, and the support roller 8 is fixedly mounted on the connecting shaft 7. The connecting shaft 7 is rotatably connected to the connecting frame 6. When the drill rod rotates, the support roller 8 will also rotate with it, thereby having an anti-deviation effect. Then the outer locking nut 4 and the inner locking nut 5 are rotated to make the inner sides of the outer locking nut 4 and the inner locking nut 5 tightly fit with the side of the anti-deviation ring 2. Finally, the remaining screw rods 3 are adjusted in the same way, so that drill rods of different diameters can also be prevented from deviating, and the application surface is wide.

[0031] like Figure 1 ,and Figure 3As shown, dust will be generated when the reverse drilling rig body 1 is working. An air suction pipe 9 is provided inside the anti-deviation ring 2, and the air suction pipe 9 is communicated with the air suction cylinder 10. An air inlet 12 is provided inside the anti-deviation ring 2, and the air suction pipe 9 is communicated with the filter box 13 through the air inlet 12. When the air suction pump 14 is started, the air suction pump 14 can draw the air inside the anti-deviation ring 2 from the air suction cylinder 10 into the air suction pipe 9, and then transport it to the filter box 13 to prevent the dust generated during drilling from dispersing. In addition, the air suction cylinders 10 are distributed in an array on the inner side of the anti-deviation ring 2, so as to extract the air around the drill pipe, and have a good dust removal effect. A dustproof filter 11 is provided inside the air suction cylinder 10, and the dustproof filter 11 can prevent larger impurities such as gravel from entering the air suction pipe 9 through the air suction cylinder 10, resulting in blockage of the air suction pipe 9, which is not conducive to the extraction of dust.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, a filter screen 15 is arranged inside the filter box 13, and the filter screen 15 can filter the extracted air to prevent dust from being discharged into the atmosphere without being filtered, thereby causing secondary pollution. A slag discharge port 16 is provided on the side of the filter box 13, and a box door 17 is arranged on the outer side of the slag discharge port 16. By turning and opening the box door 17, impurities in the filter box 13 can be cleaned from the slag discharge port 16, thereby facilitating the suction pump 14 to extract air, which is beneficial to extending the service life of the suction pump 14.
