Description

Technical Field

[0001] The present invention relates to the technical field of steel formwork detection equipment, and specifically to a surface flatness detection device based on steel formwork production. Background Art

[0002] In the field of construction, steel formwork, as a key mold for concrete pouring, its quality is directly related to the forming accuracy and quality stability of building components. Steel formwork needs to have characteristics such as high strength, high stiffness, and high surface flatness to ensure that the cast concrete components have accurate dimensions and smooth surfaces. However, during the production process of steel formwork, due to factors such as differences in raw material properties, fluctuations in processing technology, and the assembly accuracy of molds, the surface flatness of steel formwork is prone to deviation, which not only leads to a decline in the quality of concrete components but also may increase potential safety hazards and post-construction repair costs during the construction process.

[0003] Currently, the detection of the surface flatness of steel formwork mainly relies on traditional manual tools and some special detection instruments. Manual tools such as feeler gauges and straightedges are easy to operate and low in cost, but they have obvious deficiencies in detection accuracy, and the overall detection efficiency for large steel formwork is low, making it difficult to meet the quality control requirements of modern large-scale production. Although special detection instruments have improved in measurement accuracy, they generally have the following problems: First, many detection instruments have poor adaptability to the shape and size of steel formwork. Facing steel formwork of different specifications, it is necessary to frequently replace customized fixtures or perform complex equipment adjustments, which not only consumes a large amount of time and labor costs but also limits the flexibility and versatility of the detection work. Second, although some optical flatness measuring instruments can achieve high-precision non-contact measurement, they have extremely high requirements for the cleanliness of the steel formwork surface. In the actual production environment, the surface of the steel formwork is inevitably contaminated with impurities such as dust and oil, which will affect the accuracy and reliability of the measurement signal, and even lead to measurement failure. Moreover, traditional cleaning methods mostly rely on manual wiping, with low efficiency and unable to be efficiently connected with the detection process.

[0004] Based on this, those skilled in the art have proposed a surface flatness detection device based on steel formwork production to solve the above problems. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a surface flatness detection device based on steel formwork production, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A surface flatness detection device based on the production of steel formwork, including a detection table. Two mounting seats are fixedly installed on the top of the detection table. A driving gear is movably connected through a bearing in the middle side of the interior of the mounting seat. Two guide rails are installed on the top of the mounting seat. Two connecting plates are slidably connected to the outside of the guide rails. A telescopic rod is installed on the top of the mounting seat. A driving rack is installed on the outside of the mounting seat. The telescopic end of the telescopic rod is fixedly connected to the outside of the connecting plate. Two support frames are fixedly connected to the top of the detection table. An electric guide rail I is installed on the top of the support frame. A fixing frame is installed on the outside of the electric guide rail I through an electric slider. An electric guide rail II is installed on the outside of the fixing frame. An adapter frame is installed on the outside of the electric guide rail II.

[0007] Through the above technical solutions, through the coordinated work of each component, the stable clamping and flexible adjustment of the steel formwork are realized. At the same time, a stable and movable support platform is provided for detection components such as an optical flatness measuring instrument, improving the versatility, flexibility and accuracy of detection.

[0008] Preferably, two dual-axis motors are installed at the inner bottom of the detection table. One output end of the dual-axis motor is fixedly connected to a transmission shaft. Two bevel gears I are fixedly connected to the outside of the transmission shaft. Two bevel gears II are movably connected through a rotating shaft on the inner side of the detection table.

[0009] Through the above technical solutions, the dual-axis motor drives the transmission shaft and the bevel gears I to rotate. Through the meshing transmission of the bevel gears I and the bevel gears II, power is provided for the operation of subsequent components such as the driving gear, realizing the clamping and adjustment functions of the steel formwork.

[0010] Preferably, the outside of the two bevel gears I is respectively meshed and connected to the outside of the bevel gears II at the corresponding positions. The top of the bevel gear II is fixedly connected to the outside of the driving gear through a rotating shaft.

[0011] Through the above technical solutions, through the meshing connection of the bevel gears I and the bevel gears II, power is transmitted to the driving gear. Its function is to realize the effective transmission and direction conversion of power, indirectly realizing functions such as clamping and fixing the steel formwork, ensuring the stable operation of the device.

[0012] Preferably, two driving cylinders are installed on the top of the adapter frame. The output end of one of the driving cylinders is fixedly installed with an optical flatness measuring instrument. The output end of the other driving cylinder is fixedly installed with a cleaning brush. The cleaning brush is used to handle the dust on the outer surface of the steel formwork.

[0013] Through the above technical solution, two driving cylinders are used to drive the optical flatness measuring instrument and the cleaning brush respectively, so as to realize the dust cleaning and high-precision flatness measurement of the steel formwork surface, ensuring the reliability of the detection results.

[0014] Preferably, a connecting cylinder is fixedly connected to the outside of the detection table. A rubber piston is slidably connected inside the connecting cylinder. A movable rod is fixedly connected to the outside of the rubber piston. A connecting pipe communicates with the outer surface of the connecting cylinder. A plurality of negative pressure pipes communicate with the outside of the connecting pipe. A fixed cylinder is installed on the outside of the connecting frame.

[0015] Through the above technical solution, by the reciprocating movement of the rubber piston in the connecting cylinder, suction is generated using Bernoulli's principle, and dust is collected into the fixed cylinder through the negative pressure pipes, avoiding dust diffusion, keeping the detection environment clean, and ensuring that the optical flatness measuring instrument can obtain more accurate measurement data.

[0016] Preferably, an air inlet pipe also communicates with the outer surface of the connecting cylinder. Check valves are installed inside both the air inlet pipe and the connecting pipe, and the conduction directions of the two check valves are opposite.

[0017] Through the above technical solution, due to the opposite conduction directions of the check valves in the air inlet pipe and the connecting pipe, it is ensured that the gas can only flow in one direction, thereby cooperating with the movement of the rubber piston to achieve the inhalation and compression of air, providing necessary air flow control for dust collection.

[0018] Preferably, the cross-sectional area of the connecting cylinder is larger than that of the connecting pipe, and one end of the connecting pipe communicates with the inside of the fixed cylinder.

[0019] Through the above technical solution, by utilizing the difference between the larger cross-sectional area of the connecting cylinder and the smaller cross-sectional area of the connecting pipe, the flow rate of the gas increases after entering the connecting pipe. Combining with Bernoulli's principle, negative pressure is generated, enhancing the suction effect, so as to more effectively collect dust through the negative pressure pipes and introduce it into the fixed cylinder communicating with the connecting pipe.

[0020] Preferably, another output end of the double-shaft servo motor is fixedly connected with a driving turntable. A connecting rod is rotatably connected to an eccentric position outside the driving turntable. One end of the connecting rod is hinged to one end of the movable rod.

[0021] Through the above technical solution, the double-shaft servo motor drives the driving turntable to rotate. The eccentrically connected connecting rod converts the rotational motion into the reciprocating linear motion of the movable rod, thereby driving the rubber piston to slide in the connecting cylinder and realizing the compression and flow of the gas.

[0022] Preferably, the outer sides of both driving racks are meshed and connected with the outer side of the driving gear. A plurality of fixed suction cups are installed on the outside of the connecting plate.

[0023] Through the above technical solution, the driving gear drives the driving rack to move, enabling the fixed suction cups on the connecting plate to adjust their positions, achieving stable and precise clamping of steel formworks of different specifications, and improving the versatility and flexibility of the detection device.

[0024] The present invention provides a surface flatness detection device based on the production of steel formworks. It has the following beneficial effects: 1. The present invention realizes stable and precise clamping of steel formworks with different shapes and sizes, can effectively adapt to steel formworks of different specifications, without the need to frequently replace fixtures or perform complex adjustments, greatly improving the versatility and flexibility of detection. In cooperation with a high-precision optical flatness measuring instrument, non-contact measurement of the steel formwork surface can be carried out, ensuring the accuracy and reliability of the measurement results, avoiding damage to the template surface that may be caused by traditional contact measurement. At the same time, in cooperation with the electric guide rail and the electric slider, the optical flatness measuring instrument has a plane moving function, realizing comprehensive and systematic detection of large-area steel formworks.

[0025] 2. The present invention pre-treats the surface of the steel formwork by setting a cleaning brush, effectively removing dust, impurities, etc. attached to the surface, ensuring that the optical flatness measuring instrument can obtain more accurate measurement data, thereby improving the reliability and accuracy of the detection results. At the same time, using the Bernoulli principle, the dust generated during the cleaning process is directionally collected into the fixed cylinder, avoiding the random diffusion of dust in the detection environment and keeping the detection environment clean.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to the attached Figure 1 - attached Figure 7 Referring to the attached drawings, the present invention provides a surface flatness detection device based on the production of steel formwork, including a detection table 1. Two mounting seats 401 are fixedly installed on the top of the detection table 1. A driving gear 402 is movably connected to the middle side inside the mounting seat 401 through a bearing. Two guide rails are installed on the top of the mounting seat 401. Two connecting plates 405 are slidably connected to the outside of the guide rails. A telescopic rod 404 is installed on the top of the mounting seat 401. A driving rack 403 is installed on the outside of the mounting seat 401. The telescopic end of the telescopic rod 404 is fixedly connected to the outside of the connecting plate 405. Two support frames 2 are fixedly connected to the top of the detection table 1. An electric guide rail 1 301 is installed on the top of the support frame 2. A fixed frame 302 is installed on the outside of the electric guide rail 1 301 through an electric slider. An electric guide rail 2 304 is installed on the outside of the fixed frame 302. A connecting frame 303 is installed on the outside of the electric guide rail 2 304. The outside of both driving racks 403 is meshed with the outside of the driving gear 402. A plurality of fixed suction cups 406 are installed on the outside of the connecting plate 405.

[0030] Specifically, the detection table 1 serves as the device foundation, providing an installation platform and stable support for other components. The driving gear 402 meshes with the driving rack 403, converting rotational motion into linear motion, driving the driving rack 403 and the connecting plate 405 to move, and realizing the adjustment of the clamping position. The guide rail provides a sliding track for the connecting plate 405, ensuring the smooth movement of the connecting plate 405 and guaranteeing the accuracy of the clamping action. The connecting plate 405 is connected to the fixed suction cup 406, and the clamping position is adjusted as the driving rack 403 moves. The telescopic rod 404 assists the movement of the connecting plate 405 through telescopic action, providing additional positioning and support, and enhancing the stability of the clamping system. The fixed suction cup 406 uses adsorption force to achieve stable clamping, adapting to the surfaces of steel formworks with different specifications and shapes.

[0031] The electric guide rail 1 301 drives the fixed frame 302 to move, providing a large-range position adjustment function, expanding the detection range, and improving the detection flexibility. The electric guide rail 2 304 drives the connecting frame 303 to move, thus realizing the movement effect of the optical flatness measuring instrument 306 and the cleaning brush 307.

[0032] By using the meshing transmission of the driving gear 402 and the driving rack 403, the rotational motion of the driving gear 402 is converted into the linear motion of the driving rack 403, and then the connecting plate 405 is driven to move along the guide rail, and the clamping and fixing of the steel formwork are realized in cooperation with the fixed suction cup 406. This design avoids the cumbersome operations of frequently replacing fixtures or making complex adjustments, and greatly improves the versatility and flexibility of detection.

[0033] Two dual-axis motors are installed at the inner bottom of the detection table 1. One output end of the dual-axis motor is fixedly connected with a transmission shaft 502, and two bevel gears 1 503 are fixedly connected to the outside of the transmission shaft 502. The inner side of the detection table 1 is movably connected with two bevel gears 2 504 through a rotating shaft. The outer sides of the two bevel gears 1 503 are respectively meshed with the outer sides of the corresponding bevel gears 2 504, and the top of the bevel gear 2 504 is fixedly connected with the outside of the driving gear 402 through a rotating shaft.

[0034] Specifically, when starting the dual-axis motor, one of its output ends rotates and drives the transmission shaft 502 to rotate synchronously. The transmission shaft 502 is connected to two bevel gears 1 503 and rotates synchronously therewith. The bevel gear 1 503 meshes with the bevel gear 2 504, driving the bevel gear 2 504 to rotate. The bevel gear 2 504 is connected to the driving gear 402 through a rotating shaft, and then drives the driving gear 402 to rotate synchronously.

[0035] Two driving cylinders 305 are installed on the top of the connecting frame 303. The output end of one of the driving cylinders 305 is fixedly installed with an optical flatness measuring instrument 306, and the output end of the other driving cylinder 305 is fixedly installed with a cleaning brush 307. The cleaning brush 307 is used to remove the dust on the outer surface of the steel formwork.

[0036] Specifically, the measuring instrument is used for non-contact flatness detection of the surface of the steel formwork, and can accurately obtain the flatness data of the surface of the steel formwork. The function of the cleaning brush 307 is to pre-treat the outer surface of the steel formwork, effectively removing impurities such as dust attached to the surface, so as to ensure that the optical flatness measuring instrument 306 can obtain more accurate measurement data and improve the reliability and accuracy of the detection results.

[0037] A connecting cylinder 706 is fixedly connected to the outside of the detection table 1. A rubber piston 704 is slidably connected inside the connecting cylinder 706. An active rod 705 is fixedly connected to the outside of the rubber piston 704. A connecting pipe 701 communicates with the outer surface of the connecting cylinder 706. A plurality of negative pressure pipes 703 communicate with the outside of the connecting pipe 701. A fixed cylinder 702 is installed on the outside of the connecting frame 303. An air inlet pipe 6 also communicates with the outer surface of the connecting cylinder 706. Check valves are installed inside both the air inlet pipe 6 and the connecting pipe 701, and the conduction directions of the two check valves are opposite. The cross-sectional area of the connecting cylinder 706 is larger than that of the connecting pipe 701. One end of the connecting pipe 701 communicates with the inside of the fixed cylinder 702. The other output end of the dual-axis servo motor is fixedly connected to a driving turntable 505. An eccentric part of the outside of the driving turntable 505 is rotatably connected to a connecting rod 501. One end of the connecting rod 501 is hinged to one end of the active rod 705.

[0038] Specifically, the rubber piston 704 slides inside the connecting cylinder 706, dividing the connecting cylinder 706 into two variable air chambers, and realizing the inhalation and compression of gas through left and right reciprocating motions. The active rod 705 converts the rotational motion of the driving turntable 505 into a linear reciprocating motion of the rubber piston 704. The connecting pipe 701 communicates the connecting cylinder 706 and the fixed cylinder 702, providing a channel for compressed air to flow to the fixed cylinder 702. One end of the negative pressure pipe 703 communicates with the connecting pipe 701, and the other end is distributed in the cleaning area, using the negative pressure generated by the compressed air to adsorb dust and collecting it into the fixed cylinder 702. Check valves are respectively installed inside the air inlet pipe 6 and the connecting pipe 701, and their conduction directions are opposite, ensuring that the gas can only flow in one direction. The check valve of the air inlet pipe 6 ensures that the outside air can only enter the connecting cylinder 706, and the check valve of the connecting pipe 701 ensures that the compressed air can only enter the connecting pipe 701 and flow to the fixed cylinder 702, avoiding gas backflow. One end of the connecting rod 501 is eccentrically connected to the driving turntable 505, and the other end is hinged to the active rod 705, converting the rotational motion of the driving turntable 505 into a left and right reciprocating linear motion of the active rod 705.

[0039] The rotation of the turntable 505 is driven by a biaxial motor, which drives the connecting rod 501 and the movable rod 705, causing the rubber piston 704 to reciprocate left and right within the connecting cylinder 706. Utilizing Bernoulli's principle, during the movement of the rubber piston 704, controlled by the one-way valve, outside air enters the connecting cylinder 706 through the air inlet pipe 6, and then is compressed and enters the connecting pipe 701 at high speed, generating suction. This suction collects the dust generated during the cleaning process into the fixed cylinder 702 through the negative pressure pipe 703, preventing dust diffusion, maintaining the cleanliness of the detection environment, ensuring the accuracy of the measurement data of the optical flatness measuring instrument 306, and enhancing the reliability of the detection results.

[0040] Working principle: When specifically using this device, it includes the following operating principles: The steel formwork to be detected is steadily placed inside the mounting seat 401. Subsequently, one of the output ends of the biaxial motor is started, and the rotation of this output end drives the corresponding rotation of the transmission shaft 502, thereby causing the two bevel gears one 503 to rotate synchronously. The bevel gear one 503 is meshed with the bevel gear two 504. Driven by the bevel gear one 503, the bevel gear two 504 starts to rotate and transmits the power to the driving gear 402 through the rotating shaft, causing it to rotate synchronously. At this time, the two driving racks 403 slide along the outer surface of the mounting seat 401 under the meshing action of the driving gear 402, thereby driving the connecting plates 405 to move away from or approach each other along the outer surface of the guide rail. By adjusting the position of the connecting plates 405 and cooperating with the fixed suction cups 406, steel formworks of different specifications can be firmly and accurately clamped and fixed, eliminating the need for frequent fixture replacement or complex adjustments, and greatly improving the versatility and flexibility of the detection.

[0041] Start one of the driving cylinders 305 to drive the cleaning brush 307 to move downward until the cleaning brush 307 gently touches the outer surface of the steel formwork. At the same time, start the other output end of the dual-axis motor, which drives the driving turntable 505 to rotate. The eccentric part of the driving turntable 505 is hinged to the movable rod 705 through the connecting rod 501, causing one end of the connecting rod 501 to swing. Under the traction of the connecting rod 501, the movable rod 705 makes a reciprocating left and right movement. The movement of the movable rod 705 enables the rubber piston 704 to make a reciprocating left and right movement along the inner wall of the connecting cylinder 706. When the rubber piston 704 moves along the direction of the movable rod 705, the one-way valve inside the connecting pipe 701 is closed, while the one-way valve inside the air inlet pipe 6 is opened, and the outside air enters the inside of the connecting cylinder 706 through the air inlet pipe 6. When the rubber piston 704 moves away from the direction of the movable rod 705, the air inside the connecting cylinder 706 is compressed and transported into the connecting pipe 701. Since the cross-sectional area of the connecting pipe 701 is much smaller than that of the connecting cylinder 706, when the air enters the connecting pipe 701, its speed increases rapidly. According to Bernoulli's principle, the faster the gas flow rate, the smaller its pressure, so that the pressure inside the connecting pipe 701 is smaller, and then a suction force is generated inside the negative pressure pipe 703, which can effectively absorb and collect the dust generated during the cleaning process into the fixed cylinder 702, avoid the random diffusion of dust in the detection environment, keep the detection environment clean, ensure that the optical flatness measuring instrument 306 can obtain more accurate measurement data, and thus improve the reliability and accuracy of the detection results.

[0042] Finally, start the other driving cylinder 305 to drive the optical flatness measuring instrument 306 to move downward until the optical flatness measuring instrument 306 is about to touch the upper part of the steel formwork. At this time, through the cooperation of the electric guide rail 1 301 and the electric guide rail 2 304, the fixing frame 302 and the connecting frame 303 drive the optical flatness measuring instrument 306 to perform a planar movement on the surface of the steel formwork, realizing non-contact measurement of the surface of the steel formwork. The optical flatness measuring instrument 306 uses optical principles to accurately detect the flatness of the surface of the steel formwork, can obtain high-precision measurement data, ensure the accuracy and reliability of the measurement results, and at the same time avoid the damage that may be caused to the surface of the formwork by traditional contact measurement.
