[0002] Hydraulic drilling is a process that uses hydraulic principle to drive and realize drilling operation. It is often used when drilling holes for the installation of engineering structure connectors to install corresponding electronic components or monitoring equipment. In order to improve drilling efficiency and shorten the workflow of continuous drilling, traditional drilling devices usually install a full-cover bracket on the working surface where the hole is required, and then install the corresponding drilling device on the bracket;

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention can meet the high-efficiency operation of all-round hole opening through the coordination of structures such as mobile slide rails, rotating bases and fixed bases through the installation of a fixed base once, thereby ensuring the construction period.

[0020] Third, the present invention can automatically generate negative pressure after the suction cup contacts the working surface through the coordination of the rack gear, the spring and the piston rod, so that the suction cup contacts the working surface more firmly, further improving the stability of the drill during operation, and making the hole opening quality higher.

[0021] The self-adsorption method using suction cups is also suitable for most water conservancy engineering components such as gates, valves, anchors, etc. made of stainless steel and aluminum-titanium alloys. This device does not need to consider whether the component material contains magnets. Compared with some traditional methods that use magnets for additional support and fixation, this device is more effective in the drilling direction of gates, valves, and anchors made of stainless steel and aluminum-titanium alloys.

[0022] Fourth, the present invention uses the coordination of structures such as the fixed axis, the processing axis and the hinged rod, and utilizes the horizontal movement of the cleaning plate to scrape and sweep the working surface area that the suction cup is about to contact before the suction cup contacts the working surface, so that the algae growing on the underwater working surface can be scraped off, ensuring the firm effect of subsequent self-adsorption of the suction cup, thereby providing an auxiliary measure for achieving good hole opening conditions;

[0023] At the same time, this process is carried out before the suction cup contacts, and it also utilizes the characteristics of the mechanical structure movement to achieve the process of first processing the working surface and then self-adsorption.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0037] A contact rod group 9 and two suction cups 10 are provided below the housing 6, and two groups of stabilizing components are provided inside the housing 6;

[0038] By setting two groups of stabilizing components, the contact rod group 9 and the two suction cups 10 move vertically downward synchronously;

[0039] The moving parts include: two fixed slide rails 11, the two fixed slide rails 11 are fixedly connected to the upper surface of the rotating base 2, the surfaces of the two fixed slide rails 11 are slidably sleeved with moving slide rails 12, and the mounting plate 4 is fixedly connected to the upper surfaces of the two moving slide rails 12;

[0040] The stabilizing component comprises: an outer frame 13, the inner wall of the outer frame 13 is slidably connected with the inner frame 14, the lower surface of the inner wall at the top of the outer frame 13 is fixedly connected with a limiting rod 15, the top of the inner frame 14 is provided with a through hole 1 for the limiting rod 15 to slide through, the rod wall of the limiting rod 15 is sleeved with a spring 16, the two ends of the spring 16 are respectively fixedly connected with the lower surface of the inner wall at the top of the outer frame 13 and the upper surface of the inner frame 14, the inner wall of one side of the outer frame 13 is fixedly connected with a rack row 17, the lower surface of the inner wall at the top of the inner frame 14 is fixedly connected with two connecting rods 18, the inner walls of the two connecting rods 18 are connected with a fixed shaft 19 for rotating together, the shaft wall of the fixed shaft 19 is fixedly connected with a residual gear 20, the teeth of the residual gear 20 are meshed with the teeth of the rack row 17, and the lower ends of the two connecting rods 18 are fixedly connected with the upper surface of the contact rod group 9;

[0041] The bottom of the outer frame 13 is slidably connected with a connecting pipe 21, the lower end of the connecting pipe 21 is fixedly connected with the top of the suction cup 10, and the tube wall of the connecting pipe 21 is sleeved with a spring 22, and the two ends of the spring 22 are fixedly connected with the lower surface of the outer frame 13 and the upper surface of the suction cup 10 respectively;

[0042] A driving plate 32 is fixedly connected to the opposite sides of the two outer frames 13, a cylinder 33 is fixedly installed on the top of the outer shell 6, and the output end of the cylinder 33 is fixedly connected to the upper surface of the driving plate 32, and two groups of processing components are also included.

[0043] More specifically, in this embodiment: when it is necessary to drill a hole in an area, the fixed base 1 is installed in the central area of ​​the working surface. During installation, it can be installed by installing the pin plate 3, and then the rotating base 2 can be rotated to make the fixed slide rail 11 and the movable slide rail 12 above rotate synchronously, so that the movable slide rail 12 is oriented to the position of the desired drilling, and then this direction is fixed, and then the movable slide rail 12 is moved, so that the mounting plate 4 on the movable slide rail 12 moves to the front of the target drilling position, and the drill 8 on it is located directly above the target drilling and then fixed in this position, and then the hydraulic power device 7 can be started, and the hydraulic power device 7 is moved down through the lifting device 5, and the drill 8 is driven to rotate through the hydraulic power device 7, so as to drill the target position. In this way, through the installation of the fixed base 1 once, the high-efficiency operation of drilling holes in all directions can be met, thereby ensuring the construction period. Compared with the traditional method, the cumbersome process of positioning the drilling equipment one hole at a time is greatly reduced, and the space required for the structure is greatly shortened. The drilling position is accurate and the work efficiency is improved.

[0044] In the above process, the rotation of the rotating base 2 can be driven by installing a waterproof motor in the fixed base 1, and the movement of the movable slide rail 12 can be achieved by a servo motor with a waterproof function driving a chain to move or by a servo motor with a gear rack and other transmission forms;

[0045] Considering that the drill 8 will generate a large vibration feedback when drilling a hole, in order to ensure its working stability when it is far away from the fixed base 1 and to ensure good drilling quality, the cylinder 33 can be started before drilling a hole after the drill 8 moves to the specified position, so that the driving plate 32 moves downward in the shell 6, and the outer frame 13 is synchronously driven to move downward by the downward movement of the driving plate 32. At this time, the outer frame 13 is first moved downward, and the connecting pipe 21 and the suction cup 10 are synchronously moved downward by the limiting of the spring 22. At the same time, in the process of the outer frame 13 moving downward, the inner frame 14 is synchronously driven downward by the spring 16. The transmission can make the two connecting rods 18 and the contact rod group 9 move down synchronously, that is, in the process of initial displacement, the suction cup 10 moves down synchronously with the contact rod group 9, and after moving down until the contact rod group 9 contacts the working surface to be processed, the cylinder 33 is continuously driven to make the outer frame 13 continue to move down. Since the contact rod group 9 is blocked by the working surface at this time, the connecting rod 18 and the inner frame 14 connected to the contact rod group 9 are stationary relative to the working surface, and the outer frame 13 continues to move down, synchronously driving the rack row 17 to move down, so that the residual gear 20 rotates. In this process, the spring 16 is compressed until the suction cup 10 contacts the working surface;

[0046] Through the above-mentioned method, when the drill 8 is drilling a hole, there is an additional suction cup 10 at the nearest point to provide auxiliary support. This measure can improve the drilling stability of the drill 8 from the aspect of reducing the force arm distance between the drill 8 and the fixed point of the device, thereby ensuring the drilling accuracy. At the same time, compared with some traditional methods that can be associated with directly adding rollers on the movable slide rail 12 as additional support points, this method provides stability for determining that it is moved to the drilling position and then lowered, and there is no need to consider whether there are other uneven debris on the working surface that affect the movement of the movable slide rail 12 itself, and it is more applicable.

[0047] Embodiment 2, based on the above embodiment:

[0048] See also Figures 1 to 9The adsorption component includes: a rack row 23, the rack row 23 is slidably connected to the inner wall on the other side of the inner frame 14, the teeth of the rack row 23 are intermittently meshed with the teeth of the residual gear 20, and the inner wall on one side of the outer frame 13 is fixedly connected with a fixing plate 24, and the end of the fixing plate 24 is slidably connected with a transmission rod 25 through the upper and lower ends, and the rod wall sleeve of the transmission rod 25 is provided with a spring 3 26, and the two ends of the spring 3 26 are respectively fixedly connected to the upper surface of the rack row 23 and the lower surface of the fixing plate 24, and the top of the inner frame 14 is provided with a through hole 2 for the transmission rod 25 to slide through. A connecting piece 27 is fixedly connected to the upper surface of the movable rod 25, a sliding groove for displacement of the connecting piece 27 is opened on the inner wall of one side of the outer frame 13, a piston cavity 28 is opened on the inner wall of one side of the outer frame 13, a piston plate 29 is slidably connected to the inner wall of the piston cavity 28, a piston rod 30 is fixedly connected to the lower surface of the connecting piece 27, the piston rod 30 is slidably installed on the inner wall of one side of the outer frame 13, the lower surface of the piston rod 30 is fixedly connected to the upper surface of the piston plate 29, the upper end of the connecting pipe 21 is fixedly connected to a hose 31, and the upper end of the hose 31 is fixedly connected to the bottom of the piston cavity 28.

[0049] More specifically, in the present embodiment: in the above process, the suction cup 10 first moves downward synchronously with the contact rod group 9. After the contact rod group 9 contacts the working surface, the suction cup 10 has not yet contacted the working surface. Thereafter, the continued downward movement of the suction cup 10 will cause the residual gear 20 to rotate. At the beginning of this stage, the notch of the residual gear 20 is located at the teeth of the rack row 23. Then, after the suction cup 10 contacts the working surface, the residual gear 20 has rotated a certain angle, and its notch is disengaged from the rack row 23, and its teeth are meshed with the rack row 23. At this time, the cylinder 33 can continue to be driven, so that the suction cup 10 continues to move downward for a distance while maintaining contact with the working surface. At the same time, during this process, the residual gear 20 The gear 20 will drive the rack row 23 to move, that is, the rack row 23 moves up to actively compress the spring 3 26, and the transmission rod 25 can be moved up by the upward movement of the rack row 23, so that the piston rod 30 moves up under the transmission of the connecting member 27, and then the piston plate 29 moves up in the piston cavity 28 by the upward movement of the piston rod 30. Since the piston cavity 28 itself is in a downward movement state consistent with the outer frame 13, the space of the piston cavity 28 will quickly increase, and the water covered by the suction cup 10 will be sucked into the piston cavity 28 from the hose 31, so that the suction cup 10 generates negative pressure, and the suction cup 10 is more firmly in contact with the working surface;

[0050] In this way, the stability of the drill 8 during operation can be further improved, so that the hole opening quality is higher. At the same time, the self-adsorption method also reduces the need for an additional driving source for sucking the suction cup 10 to generate negative pressure, which is further convenient to use. The self-adsorption method of the suction cup 10 is also applicable to most non-ferrous metals, and there is no need to consider whether the working surface of the drilling hole contains magnetism. Compared with some traditional methods that use magnetism for additional support and fixation, this device is also applicable to the drilling direction of the working surface of non-ferrous metal materials, and is more practical.

[0051] It is also worth noting that when the outer frame 13 moves downward and the suction cup 10 is in contact with the working surface, the suction cup 10 will push the connecting pipe 21 to slide along the inner wall of the outer frame 13. At this time, the spring 22 is compressed, and the existence of the hose 31 can adapt to the displacement of the connecting pipe 21 without affecting the process of the water covered by the suction cup 10 being sucked into the piston chamber 28.

[0052] Embodiment 3, based on the above embodiment:

[0053] See also Figures 1 to 9 The processing components include: a disc 34, a slot for the fixed shaft 19 to penetrate and move vertically is opened on the outer surface of the shell 6, the disc 34 is fixedly connected to the end of the fixed shaft 19 extending out of the shell 6, a processing shaft 35 is fixedly connected to the surface of the disc 34, a horizontal displacement groove is opened on the outer surface of the shell 6, a hinge rod 36 is slidably connected to the groove wall of the horizontal displacement groove, a limiting groove 37 is opened on the rod wall of the hinge rod 36, the shaft wall of the processing shaft 35 is slidably connected to the groove wall of the limiting groove 37, and a cleaning plate 38 is fixedly installed on the bottom of the hinge rod 36.

[0054] More specifically, in this embodiment: the suction cup 10 and the contact rod group 9 move downward synchronously, the contact rod group 9 contacts the working surface, and the suction cup 10 has not yet contacted the working surface. Then, the suction cup 10 continues to move downward. In this process, it can be known from the above that the residual gear 20 will rotate, so that the disc 34 is driven to rotate through the rotation of the driven fixed shaft 19. In the initial position stage, the fixed shaft 19 moves along the notch opened on the surface of the shell 6 during the downward movement along the shell 6. In the process of the disc 34 being driven to rotate, the processing shaft 35 is synchronously driven to perform circumferential displacement. Through the circumferential displacement of the processing shaft 35, the hinged rod 36 can be horizontally moved along the groove wall of the horizontal displacement groove. During this movement, the processing shaft 35 slides along the limit groove 37 on the hinged rod 36. Through the horizontal movement of the hinged rod 36, the cleaning plate 38 is synchronously driven to perform horizontal displacement. In this state, the cleaning plate 38 and the contact rod group 9 are kept in consistent and synchronous contact with the working surface.

[0055] Through the above-mentioned method, by utilizing the horizontal movement of the cleaning plate 38, the working surface area that the suction cup 10 is about to contact can be scraped and processed before the suction cup 10 contacts the working surface, so that the algae grown on the underwater working surface can be scraped off, ensuring the subsequent firm self-adsorption effect of the suction cup 10, thereby providing auxiliary measures for achieving good hole opening conditions. At the same time, this process is carried out before the suction cup 10 contacts, and the characteristics of the structural transmission are also utilized to realize the process of first treating the working surface and then self-adsorbing. The entire work process is more reasonable, efficient and practical.

[0056] Working principle: When the high-stability underwater hydraulic hole-opening device is used, the fixed base 1 is installed in the central area of ​​the working surface. During installation, it can be installed by installing the pin plate 3, and then the rotating base 2 can be rotated to make the fixed slide rail 11 and the movable slide rail 12 above rotate synchronously, so that the movable slide rail 12 is oriented to the position of the desired hole, and then this direction is fixed, and then the movable slide rail 12 is moved, so that the mounting plate 4 on the movable slide rail 12 is moved to the front of the target hole, and the drill 8 on it is located directly above the target hole and fixed in this position, and then it can be started first The cylinder 33 first moves the two outer frames 13 downward synchronously, so that the two cleaning plates 38 first contact the working surface below the suction cup 10, and this area is processed to scrape off the algae generated by being under the water surface. Then, as the cylinder 33 continues to drive, the suction cup 10 contacts this area. After the suction cup 10 contacts the bottom area, the two outer frames 13 continue to move downward, so that the water in the two suction cups 10 is quickly sucked into the piston cavity 28 through the piston cavity 28 set in the two outer frames 13, so that the two suction cups 10 quickly generate negative pressure, and they are firmly processed with the working surface;

[0057] After the suction cup 10 is firmly adsorbed, the hydraulic power device 7 can be started, the hydraulic power device 7 is moved downward through the lifting device 5, and the driven auger 8 is rotated through the hydraulic power device 7, so as to firmly open the hole at the target location. In this way, by installing the fixed base 1 once, high-efficiency operation of all-round opening can be met, thereby ensuring the construction period. Compared with the traditional method, the tedious process of positioning the hole one by one of the opening equipment is greatly reduced, and the space required for the structure is greatly shortened. The hole position is accurate, and the work efficiency is improved. At the same time, with the auxiliary function of the suction cup 10, the hole opening quality is higher and the precision is higher.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
