Description

Technical Field

[0001] The present invention relates to the technical field of hole-opening equipment, and in particular to a hole-opening device and a hole-opening method for a side wall of an integrated pipe gallery. Background Art

[0002] In the construction and maintenance of integrated pipe corridors, sidewall drilling operations are crucial. Traditional drilling devices have exposed many problems related to drill bits in actual applications, which seriously affect construction efficiency and cost control.

[0003] When drilling holes, the traditional drilling device has limitations in its own structural design. During the drilling process, due to the lack of an effective slag removal design, the waste slag generated is removed by the rotation of the drill bit itself, but the removal effect is not timely and the effect is poor. As the drilling operation continues, the waste slag gradually accumulates in the hole. These waste slags not only occupy the space in the borehole, but also tightly wrap the drill bit, greatly hindering the normal rotation of the drill bit. When the waste slag accumulates to a certain extent, the resistance to the drill bit increases exponentially, frequently causing the drill bit to get stuck. Once the drill bit gets stuck, the subsequent cleaning and maintenance work is extremely cumbersome, and construction needs to be suspended, which consumes a lot of time and cost. Moreover, frequent replacement of drill bits brings high material costs, which seriously slows down the progress of the project.

[0004] On the other hand, traditional drilling devices have serious deficiencies in the drill bit cooling process. Most of these devices are not equipped with an effective cooling system specifically for the drill bit. During the high-speed rotation and drilling process, the drill bit generates a lot of heat due to intense friction with the side wall material of the tunnel. However, this heat cannot be dissipated in time, causing the drill bit temperature to continue to rise. Excessive temperature will not only weaken the material properties of the drill bit itself, causing its key indicators such as hardness and toughness to decrease, accelerate the wear of the drill bit, but also easily cause the drill bit to deform, or even become scrapped.

[0005] Faced with these construction difficulties caused by frequent drill bit failures, there is an urgent need for an innovative hole-opening device and method for the side wall of a comprehensive pipe gallery, which can effectively solve problems such as drill bit jamming, overheating, and overloading, so as to ensure the efficient and stable opening operation of the comprehensive pipe gallery.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, during the drilling process, the drill bit is continuously pulled out of the hole to take out waste residues, which effectively prevents the accumulation of waste residues in the hole, causing the drill bit to be stuck or even broken; the waste residues are taken out in time after each advancement of drilling, which keeps the drilling environment clean, extends the service life of the drill bit, reduces the drill bit loss cost during the construction process, and improves the continuity and reliability of the overall construction.

[0017] 2. In the present invention, while drilling, the water spray assembly is triggered to start synchronously by the push rod abutting against the wall, and several nozzles rotate and spray water toward the place where the drill bit contacts the wall, which can effectively suppress the dust generated by drilling, greatly reduce the dust pollution at the construction site, improve the construction environment, and protect the health of construction workers; on the other hand, the sprayed water cools the drill bit to prevent the drill bit from being damaged due to overheating under long-term high-speed operation, further ensuring the normal working state of the drill bit and improving the stability of the hole-opening operation.

[0018] 3. The present invention cooperates with six pressure wheels with equidistant outer diameters, which can enable the electric drilling machine to advance forward at equidistant distances. The progressive advancement method not only ensures the stability of the hole opening, but also allows the drill bit to gradually penetrate into the wall, adapting to the drilling needs of walls of different materials and ensuring the service life of the drill bit.

[0019] 4. The present invention drives the adjusting disk to rotate by the second motor, so as to change the distance between the axes of the six pressing wheels and the axis of the rotating disk, thereby being able to flexibly adjust according to the actual drilling depth requirements.

[0020] 5.

The mounting plate 2 is firmly fixed on the transmission platform of the Y-axis electric slide, and the side wall of the mounting plate 2 is fixedly connected to the square sleeve 3 through a rectangular block 201 to ensure the stability of the entire structure.

When a deeper drilling depth is required, the second motor 906 drives the adjusting disk 903 to rotate, and the six bar holes 904 synchronously drive the six columnar heads 1002, so that the movable bars 1001 extend outward from the rotating disk 9 synchronously, and the axis distance of the six pressure wheels 10 relative to the axis distance of the rotating disk 9 increases, thereby meeting the drilling requirements of different depths.

The six pressing wheels 10 are tangentially matched with the outer wall of the roller 5 in turn, and then push the movable plate 4 through the roller 5; The pressure wheel 10 with the smallest outer diameter is first tangentially matched with the outer wall of one side of the roller 5, and the pressure wheel 10 with the smallest outer diameter first pushes the electric drilling machine 7 through the movable plate 4 for a short distance, and the drill bit of the electric drilling machine 7 drills a shallow hole; While the drill is advancing, the end of the push rod 81407 cooperates with the wall, the bracket plate 811 is stationary, and the strip rod 801 is synchronously advanced following the movable plate 4, then the first groove wheel 803 follows the advancement and pulls the pull rope 819, the pull rope 819 is released from the winding wheel 817, and then drives the winding wheel 817 to rotate, then the transmission rod 815 is transmitted to the bevel gear 816, then the bevel gear ring 81405 and the first annular cavity plate 81402 rotate, and the plurality of nozzles 81404 rotate accordingly; At the same time, the piston rod 807 pushes toward the inside of the piston cylinder 806, pushing the water inside the water storage tank 808 into the water inlet pipe 81406 through the water outlet check valve 810, and the water passes through the second annular cavity plate 81403 and enters the first annular cavity plate 81402, and then is sprayed out by a plurality of nozzles 81404; Then a plurality of nozzles 81404 rotate and spray water toward the place where the drill bit contacts the wall; Step 3: The pressure wheel 10 rolls toward the outer wall on the other side of the roller 5, and then detaches from the roller 5. The movable plate 4 returns to its original position under the elastic support of the first spring 6, and the second spring 820 presses against the bracket plate 811 to keep the bracket plate 811 stationary. Then, the drill bit is pulled out of the hole, taking out the waste residue in the hole, and the water spraying mechanism 8 stops spraying water. During the return process of the movable plate 4, the winding spring 81802 is tightened, thereby driving the transmission rod 815 to rotate, and the winding wheel 817 winds up the pull rope 819; During the return process of the movable plate 4, the piston rod 807 is pulled outward from the piston cylinder 806, and negative pressure is formed inside the water storage tank 808, and the water inlet check valve 809 opens to let water in; Step four, the pressure wheels 10 that increase in size equidistantly are tangentially matched with the outer wall of the roller 5 in turn, and the electric drilling machine 7 advances forward at equidistant distances; the drill bit advances at equidistant distances to drill holes, and each time the water spraying mechanism 8 rotates and sprays water toward the place where the drill bit contacts the wall, and then after one advancement, the electric drilling machine 7 returns to its position and the drill bit is pulled out of the hole, taking out the waste residue in the hole, and at the same time the water spraying mechanism 8 stops spraying water, and after the pressure wheel 10 with the largest outer diameter completes the advancement, the drilling is completed.

[0038] The drill bit is pushed forward at equal intervals to drill holes, and at the same time the drill bit is continuously pulled out of the hole to remove the waste residue in the hole, thus preventing the drill bit from getting stuck or even breaking.

[0039] It should be noted that before drilling, since there is no water inside the water storage tank 808, the six pressure wheels 10 cooperate with the roller 5 in turn to drive the movable plate 4 to reciprocate. During the return process of the movable plate 4, the piston rod 807 is pulled outward from the piston cylinder 806, and negative pressure is formed inside the water storage tank 808. The water inlet check valve 809 is opened to let in water until several nozzles 81404 spray water at the same time, and then drilling can be carried out.

[0040] If a deeper hole needs to be punched, the second motor 906 can be used to drive the adjustment disk 903 to rotate, and the six bar holes 904 can synchronously drive the six column heads 1002, so that the movable bar 1001 extends outward from the rotating disk 9 synchronously, and the axis distance of the six pressure wheels 10 relative to the axis distance of the rotating disk 9 increases, so that deeper holes can be punched.
