Description

Technical Field

[0001] This utility model relates to the field of scaffolding processing technology, specifically to a pipe cutting device for scaffolding construction. Background Technology

[0002] In the construction industry, scaffolding, as an essential temporary facility, relies primarily on rigid materials such as steel pipes for its erection. These steel pipes often need to be cut according to actual working conditions before use or after recycling to meet different length requirements. Therefore, efficient and precise steel pipe cutting is a crucial aspect of ensuring construction progress and material management.

[0003] Currently, the pipe cutting devices commonly used on construction sites typically consist of a fixed platform for clamping the steel pipe and a cutting system (such as an abrasive wheel cutter). During the cutting operation, the operator needs to manually push the steel pipe to the predetermined cutting position, relying on experience and visual estimation to control the feeding length, which is difficult to meet the needs of large-volume, high-efficiency cutting. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe cutting device for scaffolding construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe cutting device for scaffolding construction, comprising a base, a support rod fixed to the top of the base, a top plate fixed to the top of the support rod, and a movable component and a cleaning component installed on the top of the base. The movable component is used to clamp the workpiece and feed it at a fixed distance, and the cleaning component is used to clean dust to avoid affecting the feeding. The active components include: The lower fixed seat is used to clamp the workpiece in conjunction with the upper fixed seat. Ball bearings are used to feed workpieces without affecting their operation. Rubber wheels are used in conjunction with ball bearings to achieve fixed-distance feeding.

[0006] Preferably, the lower fixed seat is fixed to the top of the base, and a connecting seat is fixed to the outer surface of the lower fixed seat. A screw is rotatably connected to the bottom of the inner wall of the connecting seat. Two sets of connecting seats are provided. A sliding rod is fixed to the bottom inner side of the other set of connecting seats. An upper fixed seat is installed on the top of the lower fixed seat, and an installation rod is fixed to the outer surface of the upper fixed seat. The sliding rod passes through the installation rod and is slidably connected to the installation rod. The screw passes through the installation rod and is threadedly connected to the installation rod. The height of the upper fixed seat can be precisely adjusted by rotating the screw, thereby adapting to the clamping requirements of steel pipes of different diameters. The sliding cooperation between the sliding rod and the installation rod ensures the stability of the upper fixed seat during the lifting process, avoids skewing, and improves the stability and reliability of clamping.

[0007] Preferably, the upper fixed seat has an internal cavity, and a rotating rod is rotatably connected to the inner wall of the cavity. A rubber wheel is fixed through and attached to the rotating rod. A second motor is mounted on the inner wall of the cavity via a connecting frame. A rotating plate is fixed to the output shaft of the second motor. A fixed plate is fixed to the outer surface of the rotating plate. An abutment rod is fixed to the outer surface of the fixed plate. A connecting plate is fixed to the outer surface of the rubber wheel. The rotating rod passes through the connecting plate. A notch and an abutment groove are formed on the outer surface of the connecting plate. The second motor drives the rotating plate to rotate. The periodic rotation of the rubber wheel is achieved through the intermittent engagement of the abutment rod and the abutment groove. The notch can fit against the outer surface of the rotating plate during the non-pushing phase, effectively preventing the rubber wheel from rotating on its own. This ensures that the steel pipe only moves when pushed, achieving a precise fixed-distance feeding function.

[0008] Preferably, the cleaning component includes a scraper fixed to the outer surface of the cavity, the outer surface of the scraper being in contact with the outer surface of the rubber wheel, a collection frame inserted into the interior of the upper fixed seat, a stabilizing frame fixed to the outer surface of the upper fixed seat, and a locking block slidably connected to the inner side of the stabilizing frame. The scraper can promptly remove impurities adhering to the surface of the rubber wheel, preventing a decrease in the coefficient of friction due to the accumulation of dust or debris, thus affecting the feeding accuracy. The collection frame facilitates the centralized processing of scraped waste, keeping the inside of the equipment clean. The cooperation between the locking block and the stabilizing frame makes the disassembly and assembly of the collection frame more convenient, facilitating daily maintenance and cleaning.

[0009] Preferably, a cylinder is fixed to the top of the top plate, the bottom of the cylinder's output end penetrates the top plate, a mounting plate is fixed to the bottom of the cylinder's output end, a motor is fixed to the bottom of the mounting plate, a cutting blade is fixed to the outer surface of the motor's output shaft, a stabilizing rod is fixed to the top of the mounting plate, the top of the stabilizing rod penetrates the top plate, and the stabilizing rod is slidably connected to the top plate. The cylinder provides stable downward pressure to ensure that the cutting blade has sufficient feed force during the cutting process; the motor drives the cutting blade to rotate at high speed, achieving efficient and flat cutting results; the sliding cooperation between the stabilizing rod and the top plate enhances the guiding nature of the mounting plate when moving up and down, effectively suppressing lateral swaying and ensuring cutting accuracy and operational safety.

[0010] Preferably, a spring is fixed to the outer surface of the locking block, and the end of the spring away from the locking block is fixed to the inner wall of the stabilizing frame. A pull rod is fixed to the outer surface of the locking block, and the end of the pull rod away from the locking block passes through the stabilizing frame. The end of the locking block away from the spring is set as an inclined surface. The spring provides continuous elastic force to the locking block, so that it can firmly lock the collection frame in its natural state and prevent it from loosening due to vibration during equipment operation. The inclined surface design allows the spring to be automatically compressed and slide into the locking position when the collection frame is inserted, realizing quick installation. The pull rod is easy to operate manually, and the locking can be easily released and the collection frame can be pulled out during cleaning, which greatly improves maintenance efficiency.

[0011] Compared with the prior art, the present invention provides a pipe cutting device for scaffolding construction, which has the following advantages: 1. This pipe-cutting device for scaffolding construction, through its movable components, allows for material feeding. When feeding is required, motor two drives the rotating plate to rotate, and the contact rod periodically engages in the contact groove of the connecting plate, thereby driving the rubber wheel to rotate intermittently. Utilizing the friction between the rubber wheel and the steel pipe, the steel pipe is propelled forward a fixed distance. When the contact rod disengages from the contact groove, the notch on the connecting plate fits against the outer surface of the rotating plate, preventing the rubber wheel from rotating on its own. This allows for intermittent feeding even with continuous operation of motor two, eliminating the need for manual feeding and improving processing efficiency.

[0012] 2. This pipe-cutting device for scaffolding construction features a cleaning component. When the rubber wheel rotates, a scraper removes dust and debris from its surface, preventing accumulation and ensuring feeding accuracy. The scraped-off debris falls into a collection frame for unified collection. To remove the collection frame for cleaning, pull the lever to disengage the locking block. During installation, the collection frame is inserted into the upper fixing base, its outer surface contacting the inclined surface of the locking block and pushing it to move. Subsequently, under the action of a spring, the flat side of the locking block abuts against the outer surface of the collection frame, achieving a limiting and fixed position for easy installation.

Detailed Implementation

[0015] like Figures 1-5As shown, this utility model provides a technical solution: a pipe cutting device for scaffolding construction, including a base 1, a support rod 2 fixed to the top of the base 1, a top plate 3 fixed to the top of the support rod 2, and a movable component 8 and a cleaning component 9 installed on the top of the base 1. The movable component 8 is used to clamp the workpiece and feed it at a fixed distance, and the cleaning component 9 is used to clean dust to avoid affecting the feeding. The movable component 8 includes: a lower fixed seat 80, a connecting seat 81, a screw 82, an upper fixed seat 83, a mounting rod 84, a sliding rod 85, a ball bearing 86, a cavity 87, a rubber wheel 88, a rotating rod 89, a motor 800, a rotating plate 801, a fixing plate 802, a contact rod 803, a connecting plate 804, a contact groove 805, and a notch 806.

[0016] The lower fixed seat 80 is fixed to the top of the base 1. A connecting seat 81 is fixed to the outer surface of the lower fixed seat 80. A screw 82 is rotatably connected to the bottom of the inner wall of the connecting seat 81. Two sets of connecting seats 81 are provided. A sliding rod 85 is fixed to the bottom of the inner side of another set of connecting seats 81. An upper fixed seat 83 is installed on the top of the lower fixed seat 80. An installation rod 84 is fixed to the outer surface of the upper fixed seat 83. The sliding rod 85 passes through the installation rod 84 and is slidably connected to the installation rod 84. The screw 82 passes through the installation rod 84 and is threadedly connected to the installation rod 84. A cavity 87 is opened inside the upper fixed seat 83. A rotating rod 89 is rotatably connected to the inner wall of cavity 7. A rubber wheel 88 is fixed through and fixed to the rotating rod 89. A motor 800 is installed on the inner wall of cavity 87 through a connecting frame. A rotating plate 801 is fixed to the output shaft of motor 800. A fixing plate 802 is fixed to the outer surface of rotating plate 801. An abutting rod 803 is fixed to the outer surface of fixing plate 802. A connecting plate 804 is fixed to the outer surface of rubber wheel 88. The rotating rod 89 passes through the connecting plate 804. A notch 806 and an abutting groove 805 are opened on the outer surface of connecting plate 804. When in use, the steel pipe to be cut is placed on the lower fixed seat 80. The rotating screw 82 causes the rubber wheel 88 to engage with the ball bearing 86 to press the steel pipe. When feeding is required, the motor 800 is started, the rotating plate 801 rotates, and the contact rod 803 intermittently enters the contact groove 805, which can push the connecting plate 804 and the rubber wheel 88 fixed thereto to rotate, thus realizing fixed-distance feeding without the need for manual feeding, improving processing efficiency.

[0017] The cleaning component 9 includes a scraper 90, which is fixed to the outer surface of the cavity 87. The outer surface of the scraper 90 is in contact with the outer surface of the rubber wheel 88. A collection frame 91 is inserted into the interior of the upper fixed seat 83. A stabilizing frame 92 is fixed to the outer surface of the upper fixed seat 83. A locking block 93 is slidably connected to the inner side of the stabilizing frame 92. A spring 95 is fixed to the outer surface of the locking block 93. The end of the spring 95 away from the locking block 93 is fixed to the inner wall of the stabilizing frame 92. A pull rod 94 is fixed to the outer surface of the locking block 93. The end of the pull rod 94 away from the locking block 93 passes through the stabilizing frame 92. The end of the locking block 93 away from the spring 95 is set as an inclined surface. The scraper 90 removes dust and debris from the surface of the rubber wheel 88 to prevent accumulation from affecting the feeding accuracy. The scraped-off impurities fall into the collection frame 91. During cleaning, pulling the pull rod 94 causes the locking block 93 to disengage from the collection frame 91, allowing it to be removed for cleaning. During installation, the collection frame 91 is inserted into the upper fixing seat 83. The outer surface of the collection frame 91 abuts against the inclined surface of the locking block 93, which can drive the locking block 93 to move without affecting normal docking. Through the spring 95, the flat side of the locking block 93 can abut against the outer surface of the collection frame 91, which can limit the position of the collection frame 91.

[0018] A cylinder 4 is fixed to the top of the top plate 3. The bottom of the output end of the cylinder 4 penetrates through the top plate 3. A mounting plate 6 is fixed to the bottom of the output end of the cylinder 4. A motor 7 is fixed to the bottom of the mounting plate 6. A cutting blade is fixed to the outer surface of the output shaft of the motor 7. A stabilizing rod 5 is fixed to the top of the mounting plate 6. The top of the stabilizing rod 5 penetrates through the top plate 3 and is slidably connected to the top plate 3. When the cylinder 4 is activated, it pushes the mounting plate 6 and the motor 7 downwards, and the cutting blade completes the cutting operation. The stabilizing rod 5 ensures the stability of the cutting process.

[0019] In use, the steel pipe to be cut is placed on the lower fixed seat 80. By rotating the screw 82, the mounting rod 84 moves downward along the slide bar 85, thereby causing the rubber wheel 88 to engage with the ball bearing 86 to press the steel pipe. During cutting, the cylinder 4 is activated to push the mounting plate 6 and the motor 7 downward, and the cutting blade completes the cutting operation. The stabilizing rod 5 ensures the stability of the cutting process. After cutting, a fixed-length feeding is required. The motor 800 is activated to drive the rotating plate 801 to rotate, and the abutment rod 803 fixed on it rotates accordingly. When the abutment rod 803 rotates into the abutment groove 805 of the connecting plate 804, it pushes the connecting plate 804 and the rubber wheel 88 fixed thereto to rotate. Due to the friction between the rubber wheel 88 and the surface of the steel pipe, its rotation will drive the steel pipe to move forward a fixed distance. When the contact rod 803 rotates away from the contact groove 805, the inner wall of the notch 806 on its connecting plate 804 fits against the outer surface of the rotating plate 801, preventing the rubber wheel 88 from rotating on its own. This allows the rubber wheel 88 to rotate intermittently while the motor 800 is continuously operating, achieving fixed-distance feeding without manual feeding and improving processing efficiency. During feeding, the scraper 90 continuously scrapes away dust and debris adhering to the surface of the rubber wheel 88, preventing their accumulation from affecting the friction coefficient and feeding accuracy. The scraped-off impurities fall into the collection frame 91 below. When the collection frame 91 needs cleaning, pulling the lever 94 outwards causes the locking block 93 to compress the spring 95 and disengage from its locking position, allowing the frame to be removed for cleaning. After cleaning, the spring 95's reset action automatically locks the locking block 93 back into place.

[0020] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
