Description

Technical Field

[0001] This invention relates to the field of cutting device technology, and more specifically, to a purlin cutting device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and are treated with rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel purlins, as a type of steel structure, are made by cold bending hot-rolled steel sheets. They have thin walls, light weight, excellent cross-sectional properties, and high strength. During the construction of a steel structure, columns and purlins are used, and during installation, the columns and purlins often overlap, requiring the overlapping purlins to be cut.

[0003] Among them, the patent with announcement number CN220295989U discloses a purlin cutting device, which includes a mounting plate, a cutting mechanism and a moving mechanism. Two sets of support plates are fixedly installed on the top of the mounting plate. The cutting mechanism is located on the top of the mounting plate and includes a connecting plate, a mounting box and a rotating rod. The connecting plate is fixedly installed on the top of the mounting plate, and a rotating plate is rotatably installed between the two sets of connecting plates. The mounting box is fixedly installed on the outer side of the rotating plate, and the rotating rod is rotatably installed on the inner side of the mounting box.

[0004] This structure places the purlin between two sets of mounting wheels, with the outer sides of the mounting wheels fitting against the outer sides of the purlin. The starting of the second motor drives the two sets of gears to mesh and rotate, thus transporting and cutting the purlin. However, this structure requires the purlin to be removed and placed on the device for cutting, which is cumbersome. It is not easy for the device to move and cut on the purlin itself, nor is it convenient for cutting areas where interference occurs during purlin installation. Therefore, it is not very convenient to use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a purlin cutting device, which aims to solve the problems mentioned in the background art.

[0006] The present invention provides the following technical solution: a purlin cutting device, including a base, wherein a plurality of self-propelled cutting components are provided on one side of the base;

[0007] The self-propelled cutting assembly includes a slide plate with adjustable position set on the base. A connecting frame is installed at one end of the slide plate by bolts. A horizontal plate is fixedly set on the connecting frame. An adjustable extension rod is set on the horizontal plate. A misalignment opening is opened through the extension rod. A drive motor is embedded in one side of the inner wall of the misalignment opening. A cutting disc for cutting is set at the output end of the drive motor.

[0008] Both ends of the connecting frame are provided with angle-adjustable support frames. The top of the support frame is rotatably connected to two pulleys located on the purlin, and the sides of the support frame are rotatably connected to limit wheels located on the sides of the purlin. A connecting plate is installed on the bottom of the inner wall of the connecting frame by bolts. A first electric push rod is installed on the connecting plate by bolts. The first electric push rod passes through the horizontal plate and extends to the top of the horizontal plate. The bottom end of the extension rod is installed on the output end of the first electric push rod by bolts.

[0009] As can be seen, in the above technical solution, the first electric push rod drives the extension rod to move the cutting disc, so that the cutting disc can press against the purlin. At the same time, the drive motor drives the cutting disc to rotate to achieve the function of cutting the purlin. During the cutting process, the position of the device is adjusted by the rotation of the pulley and its friction with the purlin. This allows the purlin to be cut while it is being moved, thus improving the efficiency and convenience of purlin cutting.

[0010] Optionally, in one possible implementation, a first pulley is fixedly provided at one end of each of the plurality of pulleys, and a plurality of second pulleys are rotatably connected to the side of the connecting frame. The first pulleys and the second pulleys are connected by a transmission belt. A servo motor is bolted to the bottom of the horizontal plate, and a pulley assembly is provided at the output end of the servo motor. The pulley assembly is sleeved on the second pulley and is connected to the second pulley for transmission. A central column is embedded at both ends of the horizontal plate. The central column is rotatably connected to the horizontal plate. The top of the central column extends to the bottom of the support frame and is detachably connected to the support frame by bolts. A support seat for support is bolted to the base. A second electric push rod is bolted to the support seat. The output end of the second electric push rod extends to one end of the leftmost slide plate, and a foldable folding rod is rotatably connected to each slide plate. Two sliding rods are fixedly provided on the base. The slide plate is located on the sliding rods and is slidably connected to the sliding rods. A laser rangefinder is provided at the top of the central column, and an angle sensor is provided on the central column.

[0011] As can be seen, in the above technical solution, the support frame can be angled on the horizontal plate via the central column, allowing the support frame to be adjusted to match the curvature of the purlin via the central column. This facilitates the pulleys and cutting disc to fit tightly against the purlin, ensuring the purlin cutting accuracy. The slide plate moves along the guide rod on the base, thereby allowing the folding rod to unfold. When the folding rod unfolds, it can pull the other slide plates to move on the guide rod, realizing the function of adjusting the position of each slide plate. At the same time, the folding rod can also be detached from the slide plate, making it easy to implement... Each slide plate has an unequal distance adjustment function, which facilitates the installation of the device on the purlin for cutting the purlin. The pulley can be located on the purlin, while the limiting wheel can be located on the side of the purlin, so that the pulley and the limiting wheel can be clamped on the purlin. The pulley group is driven to rotate by the servo motor, and the pulley group drives the second pulley to rotate. When the second pulley rotates, it drives the first pulley to rotate through the transmission belt, which in turn makes the pulley rotate and rub against the purlin, realizing the function of the device moving on the purlin, which facilitates the cutting of different positions on the purlin.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. The present invention uses a first electric push rod to drive an extension rod to move the cutting disc, so that the cutting disc can press against the purlin. At the same time, the cutting disc is driven by a drive motor to rotate, thereby realizing the function of cutting the purlin. During the cutting process, the position of the device is adjusted by the rotation of the pulley and its friction with the purlin. This allows the purlin to be cut while it is being moved, thus improving the efficiency and convenience of purlin cutting.

[0014] 2. When the support frame is located on the purlin, the angle of the support frame can be adjusted on the horizontal plate via the central column. This allows the support frame to be adjusted to match the curvature of the purlin via the central column, and it also makes it easy for the pulleys and cutting disc to fit tightly against the purlin, thus ensuring the cutting accuracy of the purlin.

[0015] 3. The present invention allows the sliding plate to move along the guide of the sliding rod on the base, thereby enabling the folding rod to unfold. When the folding rod unfolds, it can pull the other sliding plates to move on the sliding rod, thereby realizing the function of adjusting the position of each sliding plate. At the same time, the folding rod can be removed from the sliding plate, making it easy to realize the function of adjusting the sliding plates to form unequal distances, so as to facilitate the installation of the device on the purlin for cutting the purlin.

[0016] 4. In this invention, after the sliding plate is adjusted, the pulley can be positioned on the purlin, while the limiting wheel can be positioned on the side of the purlin. This allows the pulley and the limiting wheel to be clamped onto the purlin. The servo motor drives the pulley assembly to rotate, which in turn drives the second pulley to rotate. When the second pulley rotates, it drives the first pulley to rotate via the transmission belt. This allows the pulley to rotate and rub against the purlin, enabling the device to move on the purlin and facilitating cutting at different positions on the purlin.

[0017] In summary, through the coordinated use of various structures, the first electric push rod drives the extension rod to move the cutting disc, allowing it to press against the purlin. Simultaneously, the drive motor rotates the cutting disc to cut the purlin. During the cutting process, the position of the device is adjusted by the friction between the rotating pulley and the purlin, enabling simultaneous purlin movement and cutting, thus improving cutting efficiency and convenience. The pulley and limit wheel can clamp onto the purlin, and the servo motor drives the belt... The rotation of the wheel assembly drives the second pulley to rotate, which in turn drives the first pulley to rotate via the transmission belt. This, in turn, causes the pulley to rotate and rub against the purlin, enabling the device to move along the purlin. This facilitates cutting at different positions on the purlin. The support frame can be angled on the horizontal plate via the central column, allowing it to be adjusted to match the curvature of the purlin. This ensures that the pulley and cutting disc fit tightly against the purlin, guaranteeing cutting accuracy. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] As attached Figure 1 - Appendix Figure 7 The purlin cutting device shown uses a self-propelled cutting assembly mounted on a base 1. A first electric push rod 6 drives an extension rod 7 to move a cutting disc 8, allowing it to press against the purlin. Simultaneously, a drive motor 9 drives the cutting disc 8 to rotate, thus cutting the purlin. During the cutting process, a pulley 11 rotates and rubs against the purlin to adjust the device's position, enabling cutting while the purlin is being moved, improving cutting efficiency and convenience. The pulley 11 and the limiting wheel 12 can clamp onto the purlin. A servo motor 16 drives a pulley assembly 17 to rotate. The pulley assembly 17 drives the second pulley 14 to rotate, which in turn drives the first pulley 13 to rotate via the transmission belt 15. This, in turn, allows the pulley 11 to rotate and rub against the purlin, enabling the device to travel on the purlin. This facilitates cutting at different positions on the purlin. The support frame 10 can be angled on the horizontal plate 4 via the central column 18, allowing the support frame 10 to be adjusted to match the curvature of the purlin. This ensures that the pulley 11 and the cutting disc 8 can fit tightly against the purlin, guaranteeing the purlin cutting accuracy. The specific structural configuration of the components is as follows.

[0029] The self-propelled cutting assembly includes a slide plate 2 with adjustable position set on the base 1. A connecting frame 3 is installed at one end of the slide plate 2 by bolts. A horizontal plate 4 is fixedly set on the connecting frame 3. An adjustable extension rod 7 is set on the horizontal plate 4. A misalignment opening 22 is opened through the extension rod 7. A drive motor 9 is embedded in one side of the inner wall of the misalignment opening 22. A cutting disc 8 for cutting is set at the output end of the drive motor 9.

[0030] Both ends of the connecting frame 3 are provided with adjustable support frames 10. The top of the support frame 10 is rotatably connected to two pulleys 11 located on the purlin, and the sides of the support frame 10 are rotatably connected to limiting wheels 12 located on the sides of the purlin. The bottom of the inner wall of the connecting frame 3 is bolted to a connecting plate 5. The first electric push rod 6 is bolted to the connecting plate 5. The first electric push rod 6 passes through the horizontal plate 4 and extends to the top of the horizontal plate 4. The bottom end of the extension rod 7 is bolted to the output end of the first electric push rod 6.

[0031] Each of the multiple pulleys 11 has a first pulley 13 fixedly mounted at one end. Several second pulleys 14 are rotatably connected to the side of the connecting frame 3. The first pulleys 13 and second pulleys 14 are connected via a transmission belt 15. A servo motor 16 is bolted to the bottom of the horizontal plate 4. A pulley assembly 17 is mounted at the output end of the servo motor 16. The pulley assembly 17 is fitted onto the second pulleys 14 and is connected to them. A central column 18 is embedded at both ends of the horizontal plate 4. The central column 18 is rotatably connected to the horizontal plate 4, and its top extends to... The bottom of the support frame 10 is detachably connected to the support frame 10 by bolts. A support seat 23 for support is installed on the base 1 by bolts. A second electric push rod 19 is installed on the support seat 23 by bolts. The output end of the second electric push rod 19 extends to one end of the leftmost slide plate 2. Each slide plate 2 is rotatably connected to a foldable folding rod 20. Two sliding rods 21 are fixedly installed on the base 1. The slide plate 2 is located on the sliding rod 21 and is slidably connected to the sliding rod 21. A laser rangefinder 24 is installed on the top of the central column 18. An angle sensor is installed on the central column 18.

[0032] According to the above structure, when in use, the staff installs the device on the purlin. During installation, the second electric push rod 19 is activated, and the output end of the second electric push rod 19 drives the leftmost slide plate 2 on the base 1 to move. The slide plate 2 moves along the guide of the slide rod 21 on the base 1, which allows the folding rod 20 to unfold. When the folding rod 20 unfolds, it can pull the other slide plates 2 to move on the slide rod 21, realizing the function of adjusting the position of each slide plate 2. At the same time, the folding rod 20 can be removed from the slide plate 2, which makes it easy to realize the function of unequal distance adjustment of each slide plate 2, so as to facilitate the device to be installed on the purlin for cutting the purlin.

[0033] When the slide plate 2 is adjusted so that the pulley 11 can be located on the purlin, and the limiting wheel 12 can be located on the side of the purlin, the pulley 11 and the limiting wheel 12 can be clamped on the purlin. The servo motor 16 drives the pulley group 17 to rotate, and the pulley group 17 drives the second pulley 14 to rotate. When the second pulley 14 rotates, it drives the first pulley 13 to rotate through the transmission belt 15. This allows the pulley 11 to rotate and rub against the purlin, realizing the function of the device moving on the purlin, which facilitates cutting processing at different positions of the purlin.

[0034] During cutting, the first electric push rod 6 drives the extension rod 7 to move the cutting disc 8, so that the cutting disc 8 can press against the purlin. At the same time, the drive motor 9 drives the cutting disc 8 to rotate to achieve the function of cutting the purlin. During the cutting process, the position of the device is adjusted by the rotation of the pulley 11 and its friction with the purlin. This allows the purlin to be cut while it is being moved, improving the efficiency and convenience of purlin cutting. The laser rangefinder 24 is set to facilitate the testing of the distance from the cutting point to the device. At the same time, the angle sensor measures the rotation angle of the support frame 10 to adapt to the curvature of the purlin.

[0035] Meanwhile, when the support frame 10 is located on the purlin, the support frame 10 can be angled on the horizontal plate 4 via the central column 18, so that the support frame 10 can be adjusted to the curvature of the purlin via the central column 18, and the pulley 11 and the cutting disc 8 can fit tightly with the purlin to ensure the cutting accuracy of the purlin.

[0036] Unlike existing technologies, this application discloses a purlin cutting device. A first electric push rod 6 drives an extension rod 7 to move a cutting disc 8, allowing the cutting disc 8 to press against the purlin. Simultaneously, a drive motor 9 drives the cutting disc 8 to rotate, thus cutting the purlin. During the cutting process, a pulley 11 rotates and rubs against the purlin to adjust the device's position, enabling purlin cutting while it is being moved, improving cutting efficiency and convenience. The pulley 11 and the limiting wheel 12 can clamp onto the purlin, and a servo motor 16 drives a pulley assembly. 17 rotates, and the pulley group 17 drives the second pulley 14 to rotate, so that when the second pulley 14 rotates, it drives the first pulley 13 to rotate via the transmission belt 15. This causes the pulley 11 to rotate and rub against the purlin, realizing the function of the device moving on the purlin. This facilitates cutting at different positions on the purlin. The support frame 10 can be angled on the horizontal plate 4 via the central column 18, which allows the support frame 10 to be adjusted to the curvature of the purlin via the central column 18. This also makes it easy for the pulley 11 and the cutting disc 8 to fit tightly against the purlin, ensuring the cutting accuracy of the purlin.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
