Description

Technical Field

[0001] This invention relates to an environmentally friendly coring system, and more particularly to an environmentally friendly coring system capable of preventing cutting waste from falling and blocking the discharge of dust and wastewater. Background Technology

[0002] A coring drill is a mechanical device used to drill holes in walls or ceilings during the construction of building water pipes. It usually consists of a coring drill assembly together with various devices used to operate the coring drill.

[0003] The commonly used core drilling rig assembly consists of the following: a base member fixed to the structure to be drilled by anchor bolts; a bracket forming a right angle with the base member and having a rack on one side thereon; a lifting carriage having a pinion that meshes with the bracket and moving up and down along the bracket by rotating a handle; and a core drilling rig mounted on the lifting carriage for drilling specific parts of the structure.

[0004] Here, the core drilling rig includes a core drill bit that penetrates the structure through frictional contact with the structure, and a drive motor that rotates the core drill bit at high speed. Examining the operation of a core drilling rig assembly with this configuration, after the base member is secured to the wall or floor surface of the structure using multiple anchor bolts, when a handle mounted on the lifting carriage is turned, the pinion of the lifting carriage engages with the rack of the support, causing the lifting carriage to move up and down along the support. At this time, when power is applied to the drive motor, the core drill bit rotates, and the high-speed rotating core drill bit advances to penetrate the structure.

[0005] Figure 1 This is a schematic diagram illustrating the use of a conventional core drill bit drilling device to perforate the bridge deck of a bridge.

[0006] When the conventional core drill bit drilling device (10) is fixed to the upper surface of the bridge deck of the bridge (20) and the core drill bit rotates, a cylindrical cutting block (30) is formed from the bridge deck.

[0007] However, since conventional coring drill bit drilling devices (10) do not have a device for holding the cutting block (30), when drilling concrete structures, especially bridge decks (20) that float on rivers or oceans, the cutting block (30) can easily fall into the river or ocean and cause pollution.

[0008] In addition, when cooling water is supplied to the cutting surface, dust and wastewater are generated, which can pollute the surrounding environment if not treated. Summary of the Invention

[0009] Technical issues

[0010] The present invention aims to provide an environmentally friendly coring rig system that can prevent cutting waste from falling and block the discharge of dust and sewage.

[0011] Technical solution

[0012] To achieve the above objectives, the environmentally friendly coring drill device of the present invention includes: a base member fixed to the structure to be drilled; a bracket vertically connected to the base member and having a rack formed on one side thereon; a lifting carriage equipped with a pinion meshing with the rack and mounted to the bracket in a liftable manner; a fixed plate connected to one side of the lifting carriage and rotatably supporting the drive shaft of a motor; a driven shaft rotatably mounted to the fixed plate and rotated by the drive shaft of the motor; a coring drill bit connected to the driven shaft; and a metal rod passing through the driven shaft and the coring drill bit and connected to the object to be cut.

[0013] The lower end of the metal rod can be fastened and connected to an anchoring screw fixed to the cutting center of the object to be cut, and the upper end of the metal rod can be fastened and supported by a screw above the driven shaft.

[0014] The device may also include a drive gear connected to the drive shaft of the motor, and a driven gear connected to the driven shaft and rotated by the drive gear.

[0015] A hose fitting for supplying air and cooling water into the driven shaft can be installed on one side of the upper end of the driven shaft.

[0016] A dust collection hood can be installed on the upper surface of the object to be cut, through which the core drill bit passes in a sealable manner, and the internal space of the dust collection hood is sealed.

[0017] The dust collection hood may include seals respectively disposed on the inner circumferential surface of the through hole through which the core drill bit passes and on the lower edge portion that contacts the object to be cut, as well as a discharge port disposed on one side of the dust collection hood for discharging dust and wastewater.

[0025] Figure 2 This is a view illustrating an environmentally friendly coring drill system / apparatus according to an embodiment of the present invention.

[0026] like Figure 2 As shown, the environmentally friendly coring drill device (100) of the present invention can also be called an environmentally friendly coring drill system, and can have various names, such as an environmentally friendly coring drill bit drilling system. The environmentally friendly coring drill device (100) of the present invention includes: a base member (110) fixed to the structure to be drilled; a bracket (120) vertically connected to the base member (110) and having a rack (122) formed on one side thereon; a lifting carriage (130) equipped with a pinion meshing with the rack (122) and mounted to the bracket (120) in a liftable manner; a fixing plate (135) connected to one side of the lifting carriage (130) and rotatably supporting the drive shaft (145) of the motor (140); a driven shaft (155) rotatably mounted to the fixing plate (135) and rotated by the drive shaft (145) of the motor (140); a coring drill bit (160) connected to the driven shaft (155); and a metal rod (170) passing through the driven shaft (155) and the coring drill bit (160) and connected to the object to be cut.

[0027] The base member (110) can be secured to the surface of the structure to be perforated by providing at least one pair of anchor screws (112) and fastening screws. Although the structure to be perforated is typically located on a floor surface such as a floor slab, it can also be secured to a wall and perforated.

[0028] The bracket (120) can be vertically connected and secured to the base member (110). Alternatively, the bracket (120) can be connected to a pivot to change the arrangement angle relative to the base member (110) and can include a fastening unit to maintain the pivot angle. A rack (122) can be formed on one side of the bracket (120) to raise and lower the lifting carriage (130) mounted on the bracket (120).

[0029] The lifting carriage (130) can be mounted to the bracket (120) in a liftable manner by engaging its internal pinion (not shown) with a rack (122). The lifting carriage (130) may include a lever (133) for rotating the pinion, so that the operator can raise and lower the lifting carriage (130) by rotating the lever (133) when operating the drilling rig (100). In addition, guide grooves (124) may be formed on both sides of the bracket (120) to guide and support the raising and lowering of the lifting carriage (130).

[0030] A fixing plate (135) can be connected to the lower part of one side of the lifting carriage (130), and a motor (140) can be mounted to the upper part of one side of the lifting carriage (130). The fixing plate (135) can rotatably support the drive shaft (145) of the motor (140). A reduction gear (142) for reducing the speed of the motor (140) can be provided below the motor (140).

[0031] The driven shaft (155) can be mounted parallel to the drive shaft (145) to the mounting plate (135). The driven shaft (155) can rotate by receiving rotational force from the drive shaft (145) of the motor (140) via a power transmission unit. Unlike the drive shaft (145), the driven shaft (155) can be formed as a hollow tube.

[0032] The core drill bit (160) can be fastened and connected to the lower end of the driven shaft (155). The core drill bit (160) can be formed into a cylindrical shape with an open bottom, and a connection hole for connection with the driven shaft (155) can be formed on its upper surface.

[0033] The metal rod (170) can pass through the driven shaft (155) and the core drill bit (160) and be connected to the object to be cut. Since the metal rod (170) is connected to the part of the structure to be cut, this part is referred to as the "object to be cut" in the structure.

[0034] The lower end of the metal rod (170) is fastened and connected to an anchor screw (172) fixed to the cutting center of the object to be cut, and the upper end of the metal rod (170) can be fastened to a screw (174) above the driven shaft (155) and supported by the screw (174).

[0035] Anchor screw (172) is a wedge-shaped anchor screw inserted into a hole drilled at the cutting center of the object to be cut. Threads can be formed on the outer circumferential surface of the lower end of the metal rod (170) to screw into the anchor screw (172).

[0036] The screw (174) may have threads formed on its inner circumferential surface, allowing the upper end of the metal rod (170) to be inserted and fastened thereto. The screw (174) may have a handle ring on its upper part for easy tightening, and the metal rod (170) may be easily lifted along with the cutting waste. A washer (176) may be inserted below the screw (174) to prevent damage to the device components due to tightening pressure.

[0037] The environmentally friendly coring rig (or system) (100) may also include a drive gear (150) connected to a drive shaft (145) of a motor (140), and a driven gear (153) connected to a driven shaft (155) and rotated by the drive gear (150). That is, the rotational force of the drive shaft (145) can be transmitted to the driven shaft (155) through a gear connection.

[0038] The drive gear (150) and driven gear (153) can be installed inside the housing mounted on the upper surface of the fixed plate (135).

[0039] The drive gear (150) can be non-rotatably connected to the lower end of the drive shaft (145). The driven gear (153) can be non-rotatably connected to the middle part of the driven shaft (155). The drive gear (150) and the driven gear (153) can be formed to have the same size, or they can be formed to have different sizes to perform secondary reduction in addition to the reduction gear (142).

[0040] A hose fitting (190) for supplying air and cooling water into the driven shaft (155) can be provided on one side of the upper end of the driven shaft (155).

[0041] A housing is provided around the upper end of the driven shaft (155), and this housing can be supported on the upper surface of the housing on which the drive gear (150) and the driven gear (153) are mounted. The upper end of the driven shaft (155) rotatably passes through the housing, and multiple through holes can be formed on the side of the upper end of the driven shaft (155). A hose connector (190) can be provided on one side of the housing, to which a hose for supplying air and cooling water can be connected. By supplying compressed air and cooling water through the hose connector (190), the heat generated in the cutting section of the core drill bit (160) can be cooled, and dust can be blown downwards.

[0042] A dust collection hood (180) can be installed on the upper surface of the object to be cut, through which the core drill bit (160) passes in a sealable manner and its internal space is sealed.

[0043] The dust collection hood (180) can generally be formed as a cylindrical or rectangular box with an open bottom. The dust collection hood (180) can be simply placed on the upper surface of the object to be cut, or it can be fixed by driving nails or fastening bolts into the upper surface of the object to be cut through a connecting rib at the lower end.

[0044] A circular through-hole through which the core drill bit (160) passes can be formed on the upper surface of the dust collection hood (180). Annular seals (182) can be provided on the inner circumferential surface of the through-hole and on the lower edge portion of the dust collection hood (180), respectively. The seals (182) are made of an elastic material such as rubber and can seal the internal space of the dust collection hood (180) to prevent sewage leakage to the outside.

[0045] A discharge port (185) for discharging dust and wastewater can be provided on one side of the dust collection hood (180). Preferably, the discharge port (185) is formed near the lower end of the side wall of the dust collection hood (180). A dust collection hose from the dust collector can be connected to the discharge port (185) to discharge dust and wastewater that have entered the interior space of the dust collection hood (180).

[0046] According to the present invention, after the object to be cut is cut with a core drill bit, when the core drilling device is separated from the structure and lifted, the cut concrete waste is suspended on a metal rod to prevent the waste from falling downwards.

[0047] Although one embodiment of the present invention has been described above, those skilled in the art will be able to make various modifications and alterations to the present invention by adding, changing, deleting or adding components without departing from the spirit of the invention as described in the claims, and these modifications and alterations will also be included within the scope of the present invention.
