Description

Technical Field

[0001] The present application relates to the technical field of water drilling machines, and in particular to a protective water drilling machine capable of blocking gravel. Background Art

[0002] The main feature of a water drill is the use of water to cool the drill bit and workpiece during the drilling process to prevent overheating and extend tool life.

[0003] The conventional structure of a water drill mostly uses a handheld booster to install a drill bit structure on the power end to drill holes, and the drill bit part is water-sealed to prevent overheating. Therefore, the use of the water drill is: the user drives the drill bit to rotate by hand-held control of the booster, and pushes the booster and the drill bit toward the object to be drilled by hand, so that the drill bit continues to go deeper to complete the drilling.

[0004] Since the water drill is manually propelled by hand, on the one hand, it needs human assistance, which is very laborious, and on the other hand, the drill bit is not positioned, and the drill bit is easily skewed and causes interference from gravel. In this regard, a protective water drill that can block gravel is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a protective water drilling rig that can block gravel, which has the advantages of saving labor in use and reducing interference from gravel.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a protective water drilling machine capable of blocking gravel, comprising a drill bit and a booster for driving the drill bit, a booster device is further provided on one side of the booster for assisting in propelling the drill bit, a positioning rod for positioning is further passed through the drill bit, and the positioning rod is connected to the booster device;

[0007] The booster device includes a cross bar, a threaded rod, a threaded sleeve threadedly connected to the threaded rod, a push rod fixedly connected to the threaded rod, and an extrusion block fixedly connected to the end of the push rod. A mounting tube is rotatably mounted on the outside of the threaded rod for connecting to the cross bar. A threaded ring is fixedly mounted on one end of the inner wall of the mounting tube, and the threaded ring is threadedly connected to one end of the cross bar.

[0008] Furthermore, the drill bit includes a drill pipe, a protective plate located on the drill pipe, and a nut head for connecting to the force adder.

[0009] Furthermore, an extension handle is fixedly mounted on the outer side of the force adding machine.

[0010] Furthermore, there are two push rods, and both push rods penetrate and are slidably connected to the threaded ring.

[0011] Furthermore, the positioning rod includes a cross bar and a self-locking head, the self-locking head is rotatably connected to the cross bar, and the connection between the self-locking head and the cross bar deviates from the center position of the self-locking head.

[0012] Furthermore, a hexagonal nut is rotatably mounted on one end of the mounting tube, and the hexagonal nut is fixedly connected to the threaded rod.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The protective water drill capable of blocking stone debris separates the drill pipe structure of the handheld booster and the drill bit from each other, and provides a cross bar to penetrate the wall to be drilled to provide positioning support, thereby helping to guide the drilling of the drill pipe and reduce the interference of stone debris caused by the deviation of the drill bit. The protective plate is used for shielding, thereby improving the safety of drilling. The built-in threaded rod and the extrusion block of the mounting tube are provided to the booster and the drill pipe on the cross bar, so that the drill pipe can be free of manual propelling by the handheld booster, thereby making it labor-saving to use.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] See also Figure 1-4In this embodiment, a protective water drilling rig capable of blocking gravel includes a drill bit and a booster 4 for driving the drill bit, wherein the drill bit includes a drill pipe 1, a protective plate 2 located on the drill pipe 1, and a nut head 3 for connecting the booster 4.

[0022] In the present application, the nut head 3 of the drill bit and the power end of the force adder 4 are connected to each other, so that the drill pipe 1 can be controlled to rotate by the force adder 4 to achieve drilling.

[0023] In this embodiment, the force adder 4 uses a conventional driven electric motor, which is driven by installing a gear on the power end of the force adder 4, and fixing a hexagonal socket 5 on one end of the transmission gear. Through the corresponding plug-in connection between the hexagonal socket 5 and the nut head 3, the power end of the force adder 4 can drive the hexagonal socket 5 to rotate through the tooth transmission, and can also drive the nut head 3 to rotate through the hexagonal socket 5.

[0024] It should be noted that a booster device is also provided on one side of the force adding machine 4 for assisting in advancing the drill bit, and a positioning rod for positioning is also passed through the drill bit, and the positioning rod is connected to the booster device.

[0025] The positioning rod in this embodiment includes a cross bar 7 and a self-locking head 8 . The self-locking head 8 is rotatably connected to the cross bar 7 , and the connection between the self-locking head 8 and the cross bar 7 deviates from the center position of the self-locking head 8 .

[0026] Such a design enables the self-locking head 8 to naturally rotate and swing downward relative to the cross bar 7 under the influence of gravity, so that the self-locking head 8 and the cross bar 7 form a T-shaped structure at the end.

[0027] In a specific embodiment, a small hole corresponding to the cross bar 7 is pre-drilled at the location where a hole needs to be drilled, such as a wall surface, and the self-locking head 8 is rotated horizontally relative to the cross bar 7 and extended to the other side of the small hole. At this time, the self-locking head 8 naturally swings down, and the cross bar 7 is pulled back so that the self-locking head 8 with a T-shaped structure at the end of the cross bar 7 can abut against one side of the wall to be drilled, and the drill pipe 1 is slidably installed on the outside of the cross bar 7, so that the positioning of the drill pipe 1 can be achieved.

[0028] It is additionally noted that holes for the cross bar 7 to pass through are formed through the drill pipe 1 , the protective plate 2 , and the nut head 3 , so that the drill bit can be installed on the outside of the cross bar 7 and move along the direction of the cross bar 7 .

[0029] In this embodiment, the hexagonal sleeve 5 on the force adding machine 4 is also penetrated with a hole for the cross bar 7 to pass through. At this time, the force adding machine 4 can also be installed on the cross bar 7 and docked with the nut head 3 of the drill part.

[0030] It should be noted that an extension handle 6 is fixedly mounted on the outer side of the force adding machine 4 , and by holding the extension handle 6 , the user can conveniently support and adjust the position of the force adding machine 4 .

[0031] The boosting device in this embodiment includes a cross bar 7 , a threaded rod 11 and a threaded sleeve 13 threadedly connected to the threaded rod 11 . A mounting tube 9 is rotatably mounted on the outside of the threaded rod 11 for connecting with the cross bar 7 .

[0032] Preferably, a threaded ring 10 is fixedly mounted on one end of the inner wall of the mounting tube 9 , and the threaded ring 10 is threadedly connected to one end of the cross bar 7 .

[0033] In the specific implementation, the cross bar 7 is first passed through the wall to be drilled, and the drill bit and the force adder 4 are installed on the cross bar 7 in turn. At this time, the cross bar 7 and the mounting tube 9 that pass through the other end of the force adder 4 can be threadedly matched with the threaded ring 10 by rotation to complete the docking.

[0034] It is worth noting that the rotation direction of the threaded rod 11 should be set to the anti-helical direction of the docking of the cross rod 7 and the threaded ring 10 to reduce interference with the installation stability of the installation pipe 9.

[0035] In this embodiment, the booster device also includes a push rod 14 fixedly connected to the threaded rod 11 and an extrusion block 15 fixedly connected to the end of the push rod 14 . There are two push rods 14 , and both push rods 14 are slidably connected to the threaded ring 10 .

[0036] Such a design enables the push rod 14 to be connected to the extrusion block 15 and also to serve as a guide rod to limit the rotation of the threaded sleeve 13 relative to the threaded rod 11 .

[0037] It should be noted that a hexagonal nut 12 is rotatably mounted on one end of the mounting tube 9 , and the hexagonal nut 12 is fixedly connected to the threaded rod 11 .

[0038] By using auxiliary tools such as wrenches to pull the hexagonal nut 12, the user can save effort in driving the threaded rod 11 to rotate. With the help of the threads of the threaded rod 11 and the threaded sleeve 13, the extrusion block 15 connected to the threaded sleeve 13 can slide along the cross bar 7 to squeeze the force adder 4 and the drill bit toward the wall to be drilled.

[0039] The working principle of the above embodiment is:

[0040] By drilling a small hole in the wall to be drilled in advance, the drilling point can be positioned, and the self-locking head 8 is rotated horizontally relative to the cross bar 7 to extend to the other side of the small hole. At this time, the self-locking head 8 naturally swings down, and the cross bar 7 is pulled back so that the self-locking head 8 with a T-shaped structure at the end of the cross bar 7 can abut against one side of the wall to be drilled. At this time, the drill pipe 1, the protective plate 2 and the nut head 3 are successively passed through the cross bar 7 and attached to the wall surface, and the hexagonal sleeve 5 on the force machine 4 is installed on the cross bar 7 corresponding to the cross bar 7, and the force machine 4 is slid so that the hexagonal sleeve 5 at the end of the force machine 4 is inserted into the nut head 3, so that The force adder 4 can control the drill pipe 1 to drill holes, and then the mounting tube 9 and one end of the cross bar 7 are rotated and threadedly connected to each other. At this time, the force adder 4 is controlled to pull the drill pipe 1 to rotate, and the hexagonal nut 12 is driven to rotate by the hand-cranked wrench tool, and the fixedly connected threaded rod 11 is driven to rotate synchronously by the hexagonal nut 12. When the threaded rod 11 is threadedly engaged with the threaded sleeve 13, the threaded sleeve 13 moves relative to the threaded rod 11, and the extrusion block 15 connected to the threaded sleeve 13 moves away from the mounting tube 9 and squeezes the force adder 4, so that the drill pipe 1 extends toward the wall, reducing the effort of human assistance.
