Description

Technology Field

[0001] The present invention relates to a scaffolding pipe surface cleaning device, and more specifically, to a scaffolding pipe surface cleaning device that can easily clean the surface of scaffolding pipes (vertical members, horizontal members) used at construction and civil engineering sites by separating and removing foreign substances such as cement residue, paint, and concrete that are attached to or fixed on the surface. Background Technology

[0002] Scaffolding pipes (vertical and horizontal members) used at construction sites must be stored after removing foreign substances, such as concrete attached to the surface, to ensure clean reuse and facilitate assembly and installation.

[0003] However, when removing foreign substances (or deposits) such as cement residue, paint, and concrete attached to the surface of pipes by hand, there is a problem that requires a lot of time and manpower in proportion to the quantity.

[0004] In particular, although attempts are made to forcibly remove foreign substances such as concrete attached to the surface using methods like brush rotation to remove foreign substances firmly attached to the pipe surface, they are not satisfactorily removed due to the solidified foreign substances such as concrete.

[0005] In other words, when scaffolding pipes are used to support formwork at construction sites, there is a risk that foreign substances such as concrete, sand, and soil may adhere to the surface, so it is necessary to remove them to ensure clean reuse.

[0006] In particular, conventionally, most workers manually removed foreign substances adhered to the surface of the pipe or cleaned the surface of the pipe by bringing a rotating brush close to it.

[0007] When removing pipes manually, long or bulky pipes are difficult to clean, and the resulting decrease in work efficiency leads to reduced productivity.

[0008] Meanwhile, a device capable of removing attachments and cleaning while straightening a pipe has been proposed, as described in Korean Patent Registration No. 10-0977657, titled "Automatic Pipe Straightening and Cleaning Device."

[0009] However, the prior art still has the problem that it can cause rust and corrosion during pipe cleaning, and cannot easily remove foreign substances such as firmly attached concrete. Prior art literature

[0010] Korean Patent Registration No. 10-0977657, Title of Invention "Automatic Pipe Calibration and Cleaning Device" (Registration Date: August 17, 2010) The problem to be solved

[0011] The present invention was created to solve the aforementioned problems and needs, and aims to provide a scaffolding pipe surface cleaning device for easily cleaning by removing foreign substances such as cement residue, paint, and concrete that are attached to or fixed on the surface of scaffolding pipes (vertical members, horizontal members) used at construction and civil engineering sites. means of solving the problem

[0012] To achieve the above-mentioned purpose, a scaffolding pipe surface cleaning device according to an embodiment of the present invention is for removing foreign substances adhering to the surface of a scaffolding pipe and comprises: a main frame; a holding part installed spaced apart in the longitudinal direction on one side and the other side of the main frame to fix both ends of the pipe; a guide bar installed in the longitudinal direction of the main frame above the holding part; a shuttle plate sliding along the guide bar; a foreign substance removal part mounted on the shuttle plate and moving together with the shuttle plate while wrapping around the circumference of one side of the pipe; and a shuttle traction part connecting one side and the other side of the shuttle plate to move the shuttle plate back and forth. The shuttle traction part can move the foreign substance removal part, which moves together with the shuttle plate along the guide bar, from one side of the pipe to the other side and then return it from the other side to the one side. Effects of the invention

[0013] According to the present invention, there is an advantage in that foreign substances such as cement residue, paint, and concrete that are firmly adhered to the surface of scaffolding pipes used at construction and civil engineering sites can be easily separated, removed, and cleaned.

[0014] In addition, by controlling the shuttle traction unit, the movement speed of the foreign matter removal unit, which removes foreign matter formed on the pipe surface along the length of the pipe, is adjusted, and there is an advantage in that cleaning efficiency can be increased by moving from one side of the pipe to the other and then returning from the other side to the one side.

[0015] In addition, there is an advantage in that the foreign matter removal unit can be moved in a straight line along the length of the pipe without rotating the pipe, allowing even foreign matter that is firmly adhered to the pipe surface to be removed.

[0016] The effects according to the present invention are not limited to those exemplified above, and a wider variety of effects are included in the specification of the present invention. Brief explanation of the drawing

[0032] Additionally, depending on the raising and lowering of the pressure cylinder (550), the first and second half-moon blocks (520, 530) may be separated from each other or docked to surround the outer surface of the pipe (P).

[0033] Additionally, the first and second crescent blocks (520, 530) may be mutually facing each other in the shape of a crescent 'U', and a docking groove (520-1) or a docking projection (530-1) may be formed correspondingly on both upper ends of the 'U'.

[0034] In another embodiment, the foreign matter removal unit (500') includes a first crushing roller (520') replacing the first crescent block (520) and a second crushing roller (530') replacing the second crescent block (530), and the second crushing roller (530') can be raised and lowered by the pressure cylinder (550).

[0035] Additionally, depending on the raising and lowering of the pressure cylinder (550), the first and second crushing rollers (520', 530') may be separated from each other or docked to surround the outer surface of the pipe (P).

[0036] In addition, the first and second crushing rollers (520', 530') are rollers arranged vertically facing each other, and the outer surface of each of the first and second crushing rollers (520', 530') is concavely carved in a crescent shape corresponding to the outer surface of the pipe (P).

[0037] Additionally, the foreign matter removal unit (500') may be formed with a corresponding guide hole (520'-1) or guide projection (530'-1) that guides the lifting of the first and second crushing rollers (520', 530').

[0038] In addition, the outer surface of each of the first and second crushing rollers (520', 530') may have a radially curved uneven crushing groove (540) formed therein.

[0039] Additionally, the shuttle towing unit (600) can move the foreign matter removal unit (500), which moves along the guide bar (300) together with the shuttle plate (400), from one side of the pipe (P) to the other side, and then return it from the other side to the one side.

[0040] Additionally, the shuttle traction unit (600) may include a traction chain (610) connecting one side and the other side of the shuttle plate (400), first and second traction gears (620, 630) that rotate in engagement with the traction chain (610) but are spaced apart from each other in the longitudinal direction, and a drive motor (650) that provides rotational power to either of the first and second traction gears (620, 630).

[0041] Additionally, it may further include a control unit (700) that controls the speed of removing foreign matter from the surface of the pipe (P) by linking the foreign matter removal unit (500) and the shuttle traction unit (600).

[0043] Then, the configuration and operation of the scaffolding pipe surface cleaning device (10) according to one embodiment of the present invention will be described in detail as follows.

[0044] The scaffolding pipe surface cleaning device (10) proposed by the present invention is a device for removing foreign substances fixed to the surface of a scaffolding pipe (P), and as shown in FIG. 1, etc., it may include a main frame (100), a holding part (200), a guide bar (300), a shuttle plate (400), a foreign substance removal part (500), and a shuttle towing part (600).

[0046] As illustrated in FIG. 1, the main frame (100) has a cuboid shape with four sides open, and has a structure in which a plurality of square frames are connected and fastened vertically and horizontally to support the load of moving members along the longitudinal direction.

[0047] In addition, the main frame (100) provides a horizontal space in which equipment or devices such as the holding part (200), guide bar (300), and shuttle plate (400) described later are installed, and can be manufactured as a frame such as a modular steel member to facilitate transportation, and can be fixed to a factory floor or the like where equipment can be installed.

[0049] As shown in FIGS. 1 and FIGS. 2, etc., the holding member (200) is a fixing member that can fix both ends of a pipe (P) by being installed spaced apart in the longitudinal direction on one side and the other side of the main frame (100).

[0050] That is, the holding part (200) is spaced apart along the longitudinal direction of the main frame (100) to grip one side and the other side of the pipe (P), and can firmly hold the pipe (P) when the foreign matter removal part (500) moves along the longitudinal direction of the pipe (P).

[0051] Additionally, as illustrated in FIGS. 4 and FIGS. 5, the holding part (200) may include a holding bracket (210) fixed to the main frame (100) and a '⊃' holder (220) installed upright on the holding bracket (210) to hold one end of the pipe (P).

[0052] Here, the lower surface of the holding bracket (210) is firmly fixed to the main frame (100) without shaking, and since the holder (220) is fixed on the firm holding bracket (210), it can hold the pipe (P) while withstanding external vibrations or shocks.

[0053] In particular, the holder (220) has a holding groove formed in the shape of a '⊃' so as to prevent movement of one end and the other end of the pipe (P).

[0055] As shown in FIGS. 1, FIGS. 4 to 6, etc., the guide bar (300) is installed vertically in parallel along the length direction of the main frame (100) above the holding part (200) and can guide the movement of the shuttle plate (400), which will be described in detail later.

[0056] In particular, the guide bar (300) is in the shape of a cylinder with a predetermined diameter and is installed in two rows, one above and one below, along the longitudinal direction of the upper part of the main frame (100) to stably guide the horizontal movement of the shuttle plate (400).

[0057] Additionally, the guide bar (300) is installed on the upper part of the main frame (100) at least larger than the length of the pipe (P), and may be an LM guide with a circular cross section that allows the shuttle plate (400) to slide smoothly.

[0059] The shuttle plate (400) is a member that can slide along the guide bar (300) in the shape of a square plate or square block, as shown in FIGS. 4 to 7, etc.

[0060] In particular, the shuttle plate (400) may have a bearing mounted on the outer circumference of the guide bar (300) so as to minimize shaking when moving horizontally along the guide bar (300).

[0061] Additionally, the shuttle plate (400) provides an upright space for mounting a foreign object removal unit (500), and a sturdy metal member of a predetermined thickness capable of sufficiently withstanding vibrations or shocks transmitted from the foreign object removal unit (500) may be applied.

[0063] The foreign matter removal unit (500) is a means for removing foreign substances (or attachments, etc.) such as cement residue, paint, and concrete that are attached to or hardened on the surface of the scaffolding pipe (P), as shown in FIGS. 2 to 8, etc.

[0064] Additionally, the foreign matter removal unit (500) is mounted on the lower side of the shuttle plate (400) to wrap around the circumference of the pipe (P) and can move together with the shuttle plate (400) to move along the longitudinal direction of the pipe (P) and remove foreign matter that is fixed to the surface of the pipe (P).

[0065] For reference, FIG. 3(a) is a drawing showing the front view of the foreign matter removal unit (500), and FIG. 3(b) is a drawing showing the side view of the foreign matter removal unit (500).

[0066] Additionally, as illustrated in FIG. 3, the foreign matter removal unit (500) may include an upright base plate (510) attached to a shuttle plate (400), a first crescent block (520) fixed to the lower part of the base plate (510), a second crescent block (530) positioned to be vertically movable on the base plate (510) in opposition to the first crescent block (520), and a pressure cylinder (550) fixed to the upper part of the base plate (510) to raise and lower the second crescent block (530).

[0067] In particular, the foreign matter removal unit (500) is configured such that a vertically standing base plate (510) can be attached parallel to the shuttle plate (400) and is detachable, allowing it to be replaced according to the intended use.

[0068] In addition, the foreign matter removal unit (500) is formed such that the size of the hollow formed by the first and second half-moon blocks (520, 530) is slightly larger than the diameter of the pipe (P), so that foreign matter (or attachments, etc.) such as cement residue, paint, and concrete on the surface of the pipe (P) can be removed while moving.

[0069] That is, as illustrated in FIG. 6, the foreign matter removal unit (500) has a first crescent block (520) that surrounds the lower side of the pipe (P) fixed to the lower side of the base plate (510), and a second crescent block (530) that surrounds the upper side of the pipe (P) corresponding to the first crescent block (520) is positioned so as to be vertically movable on the upper side of the base plate (510) at a higher position than the first crescent block (520), and a pressure cylinder (550) that is vertically movable connected to the second crescent block (530) may be installed.

[0070] Accordingly, the foreign matter removal unit (500) has a first crescent-shaped block (520) that wraps around and settles on the lower side of one end of the pipe (P), and a second crescent-shaped block (530) that is spaced apart from the upper side of one end of the pipe (P) by facing the first crescent-shaped block (520). When the second crescent-shaped block (530) is pressed by the lifting and lowering of the pressure cylinder (550), it moves together with the first crescent-shaped block (520) to completely adhere to the circumference of one end of the pipe (P), thereby removing foreign matter (or attachments, etc.) such as cement residue, paint, and concrete on the surface of the pipe (P).

[0071] Additionally, the foreign matter removal unit (500) can be docked so that the first and second crescent blocks (520, 530) are separated from each other or surround the outer surface of the pipe (P) depending on the raising and lowering of the pressurizing cylinder (550).

[0072] In addition, to increase mutual bonding strength, the first and second crescent blocks (520, 530) may have corresponding docking grooves (520-1) or docking protrusions (530-1) formed on the upper ends of the opposing crescent-shaped 'U' blocks, as shown in FIG. 4 and FIG. 6, etc.

[0073] Accordingly, the docking groove (520-1) and the docking projection (530-1) not only increase the bonding strength between the first and second crescent blocks (520, 530), but also allow the first and second crescent blocks (520, 530), which are integrally connected vertically, to maintain a predetermined air gap on the outer circumference of the pipe (P) so that they do not come off due to vibration or impact.

[0074] In addition, the docking home (520-1) and the docking projection (530-1) also include a function to guide the first and second crescent blocks (520, 530) to be connected in the correct position when docking.

[0076] As another embodiment, the foreign matter removal unit (500') proposed by the present invention may include a first crushing roller (520') replacing the first crescent block (520) and a second crushing roller (530') replacing the second crescent block (530), as shown in FIG. 8.

[0077] That is, the foreign matter removal unit (500') may include an upright base plate (510) attached to a shuttle plate (400), a first crushing roller (520') fixed to the lower part of the base plate (510), a second crushing roller (530') positioned to be vertically movable on the base plate (510) in opposition to the first crushing roller (520'), and a pressure cylinder (550) fixed to the upper part of the base plate (510) to raise and lower the second crushing roller (530').

[0078] In addition, the foreign matter removal unit (500') can easily remove solidified foreign matter by dynamically rolling the first crushing roller (520') and the second crescent block (530) along the longitudinal direction of the pipe (P).

[0079] For reference, FIG. 8 (a) is a drawing showing the front view of the foreign object removal unit (500'), FIG. 8 (b) is a drawing showing the side view of the foreign object removal unit (500'), and FIG. 8 (c) is a drawing showing the raised state of the foreign object removal unit (500').

[0080] Additionally, as shown in FIG. 8, the first and second crushing rollers (520', 530') are rollers arranged vertically facing each other, and the outer surface of each of the first and second crushing rollers (520', 530') is concavely carved in a crescent shape corresponding to the outer surface of the pipe (P).

[0081] In particular, the foreign matter removal unit (500') has an uneven crushing groove (540) formed on the outer surface of each of the first and second crushing rollers (520', 530') with radial curvature as shown in FIG. 9, so that as each of the first and second crushing rollers (520', 530') rolls, the uneven crushing groove (540) strikes the surface of the pipe (P), so the crushing efficiency is very high.

[0082] Meanwhile, as illustrated in Fig. 8 (c), the foreign matter removal unit (500') may have a corresponding guide hole (520'-1) or guide projection (530'-1) formed to guide the lifting of the first and second crushing rollers (520', 530').

[0083] Accordingly, the foreign matter removal unit (500') has a first crushing roller (520') that is concavely carved in a crescent shape and is placed around the lower half-circle surface of one side of the pipe (P), and a second crushing roller (530') that is also concavely carved in a crescent shape is placed opposite the first crushing roller (520') and is spaced apart from the upper half-circle surface of one side of the pipe (P). Since the second crushing roller (530') is pressed by the lifting and lowering of the pressure cylinder (550) and moves by rolling along the length direction of the pipe (P) together with the first crushing roller (520'), foreign matter (or attachments, etc.) such as cement residue, paint, and concrete on the surface of the pipe (P) can be easily removed, and the crushing efficiency can be maximized by striking the surface of the pipe (P) with the uneven crushing groove (540).

[0085] As illustrated in FIG. 4, the shuttle towing unit (600) is a means of movement that can move the shuttle plate (400) horizontally by connecting the shuttle plate (400) from both sides with a towing chain (610).

[0086] That is, the shuttle towing unit (600) is a device that connects one side and the other side of the shuttle plate (400) to move the shuttle plate (400) back and forth (double-acting), and can move the foreign matter removal unit (500), which moves together with the shuttle plate (400) along the guide bar (300), from one side of the pipe (P) to the other side and then return it from the other side to the one side.

[0087] Additionally, the shuttle towing unit (600) may include a towing chain (610), first and second towing gears (620, 630), and a drive motor (650).

[0088] Here, the traction chain (610) forms a closed curve by connecting one side and the other side of the shuttle plate (400) so that the shuttle plate (400) can be moved horizontally to the left or right, as shown in FIG. 1, etc.

[0089] In addition, the first and second traction gears (620, 630) are installed on one side and the other side of the main frame (100) and rotate in engagement with the traction chain (610) to provide power to move the traction chain (610).

[0090] That is, the first and second traction gears (620, 630) are installed spaced apart from each other along the longitudinal direction of the main frame (100) and rotate in engagement with the traction chain (610), thereby causing the traction chain (610) to move along the track.

[0091] Additionally, the drive motor (650) is a motor that generates driving power through a power supply, as illustrated in FIG. 1, etc., and provides rotational power to the rotation axis of either the first or second traction gear (620, 630) so that as the first or second traction gear (620, 630) rotates, one traction chain (610) that is engaged moves along the track direction.

[0093] As shown in FIG. 1, the control unit (700) is a device that is installed on one side of the main frame (100) or connected via wired or wireless connection and controls through a control signal, and can control the foreign object removal unit (500, 500') and the shuttle towing unit (600), etc. according to a set program.

[0094] In particular, the control unit (700) proposed by the present invention can control the driving motor (650) of the shuttle traction unit (600) to control the movement speed of the foreign matter removal unit (500) that cleans foreign matter formed on the surface of the pipe (P) along the longitudinal direction of the pipe (P), and can remove foreign matter by adjusting the strength according to the strength of attachment of foreign matter adhering to the surface of the pipe (P) by adjusting the distance of the pressure cylinder (550) of the foreign matter removal unit (500).

[0095] In addition, the control unit (700) can adjust the horizontal movement distance of the foreign object removal unit (500) by having a sensor (not shown) installed on the main frame (100) that can sense and control the movement of the foreign object removal unit (500).

[0096] Accordingly, the control unit (700) proposed by the present invention can control the foreign matter removal speed on the surface of the pipe (P) by controlling the pressurizing cylinder (550) and the driving motor (650), etc., according to a sensor or a set program, and linking the foreign matter removal unit (500, 500') and the shuttle traction unit (600).

[0098] In this way, the scaffolding pipe surface cleaning device (10) according to the embodiments of the present invention can be expected to have the following effects.

[0099] According to the present invention, there is an advantage in that even foreign substances such as cement residue, paint, and concrete that are firmly adhered to the surface of scaffolding pipes (P) used at construction and civil engineering sites can be easily separated, removed, and cleaned.

[0100] In addition, by controlling the shuttle towing unit (600), the movement speed of the foreign matter removal unit (500), which removes foreign matter formed on the surface of the pipe (P) along the longitudinal direction of the pipe (P), is adjusted, and there is an advantage of increasing cleaning efficiency by moving from one side of the pipe (P) to the other side and then returning from the other side to the one side.

[0101] In addition, there is an advantage in that the foreign matter removal unit (500) can be moved in a straight line along the length of the pipe (P) without rotating the pipe (P), thereby removing even foreign matter that is firmly fixed to the surface of the pipe (P).

[0103] The above description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications, changes, and substitutions within the scope of the essential characteristics of the present invention without departing from its nature.

[0104] Accordingly, the embodiments disclosed in this invention and the accompanying drawings are intended to explain, not limit, the technical concept of the invention, and the scope of the technical concept of the invention is not limited by these embodiments and the accompanying drawings.
