Description

Technical Field

[0001] The present invention relates to the technical field of tower body distance detection, and particularly relates to a new type of tower ruler system with adjustable tension and a using method thereof. Background Art

[0002] In the pressure vessel manufacturing industry, there are many vertical towers that require flow control of the tower body. During the assembly process of the tower body in the manufacturing plant, the accuracy of the reference line controls the assembly accuracy of the tower body. During the process of marking the reference line of the tower body, a steel ruler is often used for long-distance measurement. When in use, one end of the steel ruler is adsorbed on the reference line of the tower body through a magnet, and then the other end of the steel ruler is straightened by an operator for measurement. For example, the Chinese patent authorization publication number is CN214423764U, which discloses a steel tension rod with adjustable tension during the steel structure processing, and it uses a tensioned steel rod in the local lower chord of the prestressed steel structure. However, due to the too long measurement distance of the steel ruler, affected by gravity and the degree of control of the operator's force, it is impossible to ensure the unity of the force when tightening the steel ruler. Once the forces are inconsistent, it will further increase the uncertainty factors on the basis of the error of multiple measurements, and then cause a greater scribing error in the follow-up, resulting in inaccurate accuracy. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, and provide a new type of tower ruler system with adjustable tension and a using method thereof. By adding a tension assisting device, it solves the problem of inconsistent tension values caused by too long a measurement distance of the steel ruler, and thus ensures that the measurement accuracy with the reference line can be accurately controlled each time.

[0004] The technical solution adopted by the present invention is as follows: A new type of tower ruler system with adjustable tension includes a steel ruler, as well as a magnet and a tension assisting device respectively located at both ends of the steel ruler. The magnet is used to adsorb on the reference line of the tower body, and the tension assisting device is located above the magnet to keep the tension consistent for each measurement through the tightened steel ruler, wherein: the tension assisting device includes the following components: A frame body, arranged in a rectangular frame shape, for providing a supporting role; A clamping mechanism, located on the side of the frame body, includes a U-shaped part installed on the side and a nut tightened on the U-shaped part. The U-shaped part clamps on the tower body for providing a fixing role; A pulling mechanism, located in the middle of the frame body, includes a puller. One end of the puller is connected to the steel ruler, and the other end of the puller is connected to an adjusting mechanism, for visually reading the tension value of the steel ruler and keeping the tension value consistent for each measurement; The adjusting mechanism is located on the other side of the frame body and includes a support and a screw-in part. The screw-in part is connected to the tensioner and adjusts the tension of the steel tape by screwing into the support, so as to overcome the measurement error caused by different tensions of the steel tape.

[0005] In this technical solution, through the added tension assisting device, the accurate measurement of the distance between a specific position of the tower body and the reference line by the steel tape is realized, and the measurement error caused by different tension values of the steel tape due to factors such as gravity is avoided. Specifically, under the action of the tension assisting device, the steel tape is tightened to a uniform tension degree. The tightened state enables the steel tape to maintain a straight shape during the measurement process, reducing the measurement error caused by the bending of the steel tape. The tension mechanism is connected to the steel tape through the tensioner, and the tension value of the steel tape can be visually read. The adjusting mechanism is connected to the tensioner through the screw-in part and can accurately adjust the tension of the steel tape. Before each measurement, the tension of the steel tape is adjusted to a specified value through the adjusting mechanism to ensure that the tension of the steel tape is consistent during each measurement. According to Hooke's law, within the elastic limit, the elongation of the steel tape is proportional to the applied tension. Therefore, maintaining consistent tension can ensure the stability of the elongation of the steel tape during the measurement process, thereby improving the measurement accuracy. The magnet is adsorbed on the reference line of the tower body, providing a stable reference point for the measurement. With the reference point being constant and the tension of the steel tape being consistent, by reading the length of the steel tape at the measurement position, an accurate measurement result can be obtained, and the measured distance value can truly reflect the actual size of the tower body.

[0006] In addition, according to the above-mentioned novel tower ruler system with adjustable tension and its usage method of the present invention, the following additional technical features may also be provided: According to an embodiment of the present invention, the reference line of the tower body is a line drawn around the tower body, and the magnet is adsorbed on a point of the reference line, and dynamic measurement is performed relative to the reference line through the tension assisting device.

[0007] In this technical solution, through the adsorption of the magnet, not only is the operation simple, but also sufficient fixing force can be provided to ensure the stability of the position of the measurement system relative to the reference line during the measurement process and prevent deviation due to slight external interference. The setting of the reference line ensures the consistency and repeatability of the starting point of each measurement and is applicable to the shapes, sizes, and structures of different tower bodies.

[0008] According to an embodiment of the present invention, the height at which the magnet is adsorbed is not higher than the height measured by the tension assisting device, that is, when the steel tape is used vertically, the magnet is below and the tension assisting device is above; when the steel tape is used horizontally, there is no direction requirement.

[0009] In this technical solution, during actual operation, if the magnet is placed above, when it is necessary to move or adjust the measurement position, the magnet may fall due to loosening or improper operation, causing damage to the personnel and equipment below. By placing the magnet below, even in case of an accident, it will not form a falling heavy object, greatly improving the safety of operation. Different tower bodies may have different structures and measurement requirements. The flexible layout method enables the new tower ruler system to be applicable to the measurement of various tower bodies. Whether it is a tall tower or a horizontal tower base, the measurement requirements can be met by adjusting the measurement method and using the corresponding layout.

[0010] According to an embodiment of the present invention, the tower body is provided with a side edge that cooperates with the U-shaped member, and the measurement object is the distance value between the reference line and the side edge. The reading shown by the steel ruler with consistent tension is the true distance value.

[0011] According to an embodiment of the present invention, two legs are provided on the side of the frame body, and a set of clamping mechanisms are provided on each leg. The clamping mechanisms cooperate with the side edge through the U-shaped member to make the tightened steel ruler closely adhere to the tower body for measurement.

[0012] In this technical solution, compared with the single-leg structure, the double legs can better disperse the gravity and external forces borne by the system, reducing the system shaking or tilting caused by single-point support.

[0013] According to an embodiment of the present invention, a sliding track that cooperates with the forward and backward movement of the tensioner is provided in the middle of the frame body, and a U-shaped member and a support are respectively provided on both sides of the sliding track.

[0014] In this technical solution, the sliding track provides a stable movement guide for the tensioner, enabling the tensioner to maintain a linear movement during the forward and backward movement, avoiding uneven tension of the steel ruler or measurement error caused by the deviation of the movement direction of the tensioner. The sliding track is fixed on the tower body through the U-shaped member, and the tension is adjusted through the screw-in member on the support.

[0015] According to an embodiment of the present invention, when the steel ruler is used for long-distance measurement, the middle part of the steel ruler is sleeved with a guide block for auxiliary fixation. The bottom of the guide block is adsorbed on the tower body, and a socket hole is provided in the middle of the guide block for adjusting the tension of the steel ruler.

[0016] In this technical solution, when the steel ruler is used for long-distance measurement, it is easily affected by obstacles, gravity, etc., and it is impossible to ensure that the steel ruler remains horizontal or nearly horizontal throughout the measurement length. Through the middle support of the guide block, the sagging and shaking of the steel ruler at a long distance are reduced; by installing the guide block at a unified position, obstacles can be bypassed or measurement can be carried out on the undulating tower body.

[0017] According to an embodiment of the present invention, the steel ruler is connected to the tensioner through a clamping member. The tensioner adjusts the magnitude of the tension value through a screw-in member. The steel ruler shows a change in the reading before and after relative to the side edge of the tower body. When the tension value reaches the specified value, the reading of the steel ruler is the true distance value.

[0018] In this technical solution, the tensioner adjusts the magnitude of the tension value through a screw-in member. The screw-in member is a component with a threaded structure. By rotating the screw-in member, the elastic mechanism inside the tensioner can be changed, thereby achieving precise control of the tension of the steel ruler.

[0019] To achieve the above object, the present invention also provides a new type of tower ruler system with adjustable tension and its usage method.

[0020] A new type of tower ruler system with adjustable tension and its usage method include the following steps: S1. Draw a reference line on the tower body and fix one end of the steel ruler with a magnet on the reference line; fix the tension assisting device on the side edge of the tower body through a clamping mechanism; at this time, the tension assisting device is above the magnet or in the horizontal direction. S2. The steel ruler extends towards the tension assisting device and is fixed to one end of the tensioner through a clamping member. The other end of the tensioner is hooked on the adjusting mechanism. The whole tensioner is located on the sliding track of the frame body. At this time, there is an error between the tension value on the tensioner and the specified value. S3. Observe the reading of the tensioner and adjust the tension value of the steel ruler through the adjusting mechanism. When the tension value reaches the specified value, observe the reading on the side edge where the steel ruler is located. At this time, the reading represents the distance value between the reference line and the side edge, which is the true distance value.

[0021] This technical solution measures the true distance value of the tower body by first establishing an accurate starting reference point, then constructing a flexible tension adjustment mechanical structure, and finally precisely adjusting the tension. Specifically, first, an accurate starting reference point is established by drawing a reference line on the tower body and fixing one end of a steel ruler with a magnet on the reference line; the tension assist device is fixed on the side edge of the tower body through a clamping mechanism, and it is ensured that the tension assist device is above the magnet or in the horizontal direction, so that the steel ruler can be measured within a relatively fixed framework, ensuring that the starting conditions for measurement are accurate and repeatable; then, the tensioner moves freely on the sliding track to flexibly adjust the tension of the steel ruler. At this time, there is an error between the tension value on the tensioner and the specified value, which is a normal initial state because subsequent adjustments are required to reach the specified tension value; finally, by observing the reading of the tensioner, the operator can intuitively understand the current tension value and adjust the tension value of the steel ruler through the adjustment mechanism. This is a dynamic process, and the operator can precisely adjust the adjustment mechanism according to the difference between the reading of the tensioner and the target specified value, thereby changing the tension of the steel ruler; when the tension value reaches the specified value, the deformation of the steel ruler is stabilized within a specific range at this time and can accurately reflect the actual size of the tower body; at this time, observe the reading on the side edge where the steel ruler is located. Since the previous tension adjustment ensures the tightness and stability of the steel ruler, the reading at this time represents the true distance value between the reference line and the side edge.

[0022] According to an embodiment of the present invention, in S2, when the steel ruler performs long-distance measurement, a guide block is sleeved on the steel ruler in advance, and the guide block is adsorbed on the tower body to assist the steel ruler in guiding in the middle; the ruler box at the end of the steel ruler is suspended on one side of the tensioner.

[0023] With the auxiliary guidance of the guide block in this technical solution, the steel ruler can maintain a more stable form, reducing measurement errors caused by factors such as shaking, sagging, or deviation. The ruler box located on one side of the tensioner will not interfere with the observation of the tensioner reading or the fixation of the tensioner.

[0024] Compared with the prior art, the present invention has the following beneficial effects: Through the newly added magnet and tension assist device, the steel ruler for measurement is initially fixed at both ends, and then the adjustment mechanism on the tension assist device is used to finely adjust the tension value of the steel ruler, and the finely adjusted tension value is maintained at the specified value, thereby avoiding the error influence caused by factors such as the gravity of the steel ruler during multiple measurements.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0031] Embodiment 1 As Figure 1 shown, this embodiment provides a new type of tower ruler system with adjustable tension, including a steel ruler 3, and a magnet 2 and a tension assisting device 4 respectively located at both ends of the steel ruler 3. The magnet 2 is used to adsorb on the reference line of the tower body 1, and the tension assisting device 4 is located above the magnet 2 to keep the tension consistent for each measurement through the tightened steel ruler 3, wherein: As Figure 2 shown, the tension assisting device 4 includes the following components: The frame body 41 is arranged in a rectangular frame shape and is used to provide a supporting function; The clamping mechanism is located on the side of the frame body 41 and includes a U-shaped part 42 installed on the side and a nut 43 tightened on the U-shaped part 42. The U-shaped part 42 clamps on the tower body 1 and is used to provide a fixing function; The tensioning mechanism is located in the middle of the frame body 41 and includes a tensioner 44. One end of the tensioner 44 is connected to the steel ruler 3, and the other end of the tensioner 44 is connected to the adjusting mechanism, which is used to visually read the tension value of the steel ruler 3 and keep the tension value consistent for each measurement; The adjusting mechanism is located on the other side of the frame body 41 and includes a support 47 and a screwing part 48. The screwing part 48 is connected to the tensioner 44 and adjusts the tension of the steel ruler 3 by screwing the distance of the support 47, which is used to overcome the measurement error caused by different tensions of the steel ruler 3.

[0032] As Figures 1 to 2As shown in the figure, in this technical solution, by adding a tension assisting device 4, the steel ruler 3 can accurately measure the distance between a specific position of the tower body 1 and the reference line, avoiding measurement errors caused by different tension values of the steel ruler 3 due to factors such as gravity. Specifically, under the action of the tension assisting device 4, the steel ruler 3 is tightened to a uniform tension, and this tightened state enables the steel ruler 3 to maintain a straight shape during the measurement process, reducing measurement errors caused by the bending of the steel ruler 3; the tension mechanism is connected to the steel ruler 3 through a tensioner 44, and the tension value of the steel ruler 3 can be visually read; the adjusting mechanism is connected to the tensioner 44 through a screw-in member 48, and can accurately adjust the tension of the steel ruler 3; before each measurement, the tension of the steel ruler 3 is adjusted to a specified value through the adjusting mechanism to ensure that the tension of the steel ruler 3 is consistent during each measurement. According to Hooke's law, within the elastic limit, the elongation of the steel ruler 3 is proportional to the applied tension. Therefore, maintaining consistent tension can ensure the stability of the elongation of the steel ruler 3 during the measurement process, thereby improving the measurement accuracy. The magnet 2 is adsorbed on the reference line of the tower body 1, providing a stable reference point for the measurement. When the reference point is consistent and the tension of the steel ruler 3 is consistent, by reading the length of the steel ruler 3 at the measurement position, an accurate measurement result can be obtained, and the measured distance value can truly reflect the actual size of the tower body 1.

[0033] In addition, according to the above-mentioned novel tower ruler system with adjustable tension and its usage method proposed by the present invention, the following additional technical features may also be provided: According to an embodiment of the present invention, the reference line of the tower body 1 is a line drawn around the tower body 1, the magnet 2 is adsorbed at a point on the reference line, and dynamic measurement is performed relative to the reference line through the tension assisting device 4.

[0034] In this technical solution, through the adsorption of the magnet 2, not only is the operation simple, but also sufficient fixing force can be provided to ensure the stability of the position of the measurement system relative to the reference line during the measurement process and prevent deviation due to slight external interference; the setting of the reference line ensures the consistency and repeatability of the starting point of each measurement, which is applicable to the shapes, sizes, and structures of different tower bodies 1.

[0035] According to an embodiment of the present invention, the height at which the magnet 2 is adsorbed is not higher than the height measured by the tension assisting device 4, that is, when the steel ruler 3 is used vertically, the magnet 2 is below and the tension assisting device 4 is above; when the steel ruler 3 is used horizontally, there is no direction requirement.

[0036] In this technical solution, during actual operation, if the magnet 2 is placed above, when it is necessary to move or adjust the measurement position, the magnet 2 may fall due to loosening or improper operation, causing damage to the personnel and equipment below. By placing the magnet 2 below, even in case of an accident, it will not form a falling heavy object, greatly improving the safety of operation. Different tower bodies 1 may have different structures and measurement requirements. The flexible layout method enables the new tower ruler system to be applicable to the measurement of various tower bodies 1. Whether it is a tall tower or a horizontal tower base, the measurement requirements can be met by adjusting the measurement method and using the corresponding layout.

[0037] According to an embodiment of the present invention, the tower body 1 is provided with a side edge that cooperates with the U-shaped member 42. The measurement object is the distance value between the reference line and the side edge. The reading shown by the steel ruler 3 with consistent tension is the true distance value.

[0038] According to an embodiment of the present invention, two legs are provided on the side of the frame body 41. A set of clamping mechanisms is provided on each leg. The clamping mechanism cooperates with the side edge through the U-shaped member 42 to make the tightened steel ruler 3 closely adhere to the tower body 1 for measurement.

[0039] In this technical solution, compared with the single-leg structure, the double-leg can better disperse the gravity and external forces borne by the system, reducing the system shaking or tilting caused by single-point support.

[0040] According to an embodiment of the present invention, a sliding track 46 that cooperates with the forward and backward movement of the tensioner 44 is provided in the middle of the frame body 41. U-shaped members 42 and supports 47 are respectively provided on both sides of the sliding track 46.

[0041] In this technical solution, the sliding track 46 provides a stable movement guide for the tensioner 44, enabling the tensioner 44 to maintain a straight-line movement during the forward and backward movement, avoiding uneven tension of the steel ruler 3 or measurement errors caused by the deviation of the movement direction of the tensioner 44. The sliding track 46 is fixed on the tower body 1 through the U-shaped member 42, and the tension is adjusted through the screw-in member 48 on the support 47.

[0042] As Figures 3 to 4 shown, when the steel ruler 3 is used for long-distance measurement, the middle part of the steel ruler 3 is sleeved with a guide block 5 for auxiliary fixation. The bottom of the guide block 5 is adsorbed on the tower body 1. A socket hole is provided in the middle of the guide block 5 for adjusting the tension of the steel ruler 3.

[0043] In this technical solution, when the steel tape 3 is used for long-distance measurement, it is easily affected by obstacles, gravity, etc., and it is impossible to ensure that the steel tape 3 remains horizontal or nearly horizontal throughout the measurement length. Through the intermediate support of the guide block 5, the sagging and shaking of the steel tape 3 at a long distance are reduced; by installing the guide block 5 at a unified position, obstacles can be bypassed or measurement can be carried out on the undulating tower body 1.

[0044] According to an embodiment of the present invention, the steel tape 3 is connected to the tensioner 44 through the clamping member 45. The tensioner 44 adjusts the magnitude of the tension value through the screw-in member 48. The steel tape 3 shows changes in the front and back relative to the side edge of the tower body 1. When the tension value reaches the specified value, the reading of the steel tape 3 is the true distance value.

[0045] In this technical solution, the tensioner 44 adjusts the magnitude of the tension value through the screw-in member 48. The screw-in member 48 is a component with a threaded structure. By rotating the screw-in member 48, the elastic mechanism inside the tensioner 44 can be changed, thereby realizing precise control of the tension of the steel tape 3.

[0046] Embodiment 2 Based on Embodiment 1, as Figures 1 to 4 shown, this embodiment provides a new type of tower ruler system with adjustable tension and its use method, including the following steps: S1. Draw a reference line on the tower body 1, and fix one end of the steel tape 3 with the magnet 2 on the reference line; fix the tension assisting device 4 on the side edge of the tower body 1 through the clamping mechanism; at this time, the tension assisting device 4 is above the magnet 2 or in the horizontal direction. S2. The steel tape 3 extends towards the tension assisting device 4 and is fixed to one end of the tensioner 44 through the clamping member 45. The other end of the tensioner 44 is hooked on the adjusting mechanism. The tensioner 44 is entirely located on the sliding track 46 of the frame body 41. At this time, there is an error between the tension value on the tensioner 44 and the specified value. S3. Observe the reading of the tensioner 44 and adjust the tension value of the steel tape 3 through the adjusting mechanism. When the tension value reaches the specified value, observe the reading on the side edge where the steel tape 3 is located. At this time, the reading represents the distance value between the reference line and the side edge, which is the true distance value.

[0047] This technical solution realizes the measurement of the true distance value of the tower body 1 by first establishing an accurate starting reference point, then constructing a flexible tension adjustment mechanical structure, and finally precisely adjusting the tension. Specifically, first, an accurate starting reference point is established by drawing a reference line on the tower body 1 and fixing one end of the steel ruler 3 with a magnet 2 on the reference line; the tension assisting device 4 is fixed on the side edge of the tower body 1 through a clamping mechanism, and it is ensured that the tension assisting device 4 is above or in the horizontal direction of the magnet 2, so that the steel ruler 3 can be measured within a relatively fixed frame, ensuring that the starting conditions of the measurement are accurate and repeatable; then, the tensioner 44 moves freely on the sliding track 46 to flexibly adjust the tension of the steel ruler 3. At this time, there is an error between the tension value on the tensioner 44 and the specified value, which is a normal initial state because subsequent adjustments are required to reach the specified tension value; finally, by observing the indication of the tensioner 44, the operator can intuitively understand the current tension value, and adjust the tension value of the steel ruler 3 through the adjustment mechanism. This is a dynamic process, and the operator can precisely adjust the adjustment mechanism according to the difference between the indication of the tensioner 44 and the target specified value, thereby changing the tension of the steel ruler 3; when the tension value reaches the specified value, the deformation of the steel ruler 3 is stabilized within a specific range at this time, and it can accurately reflect the actual size of the tower body 1; at this time, observe the indication on the side edge where the steel ruler 3 is located. Since the previous tension adjustment ensures the tightness and stability of the steel ruler 3, the indication at this time represents the true distance value between the reference line and the side edge.

[0048] According to an embodiment of the present invention, in S2, when the steel ruler 3 performs long-distance measurement, a guiding block 5 is sleeved on the steel ruler 3 in advance, and the guiding block 5 is adsorbed on the tower body 1 to assist the steel ruler 3 in guiding in the middle; the ruler box at the end of the steel ruler 3 is suspended on one side of the tensioner 44.

[0049] With the auxiliary guiding of the guiding block 5 in this technical solution, the steel ruler 3 can maintain a more stable shape, reducing measurement errors caused by factors such as shaking, sagging, or deviation. The ruler box located on one side of the tensioner 44 does not interfere with the observation of the indication of the tensioner 44 or the fixation of the tensioner 44.

[0050] Specific usage scenarios. For another example, during the maintenance process of a chemical tower, it is necessary to measure the distance between two points at a certain height on the tower body, bypassing the protruding pipes and valves on the surface of the tower body, to determine whether there is deformation or damage in this area; there are multiple obstacles of different sizes and shapes on the surface of the chemical tower, and the tower body is made of metal and has a certain magnetism. Draw a reference line on the tower body, and adsorb one end of the steel ruler with a magnet at a position on the reference line close to the starting point of the measurement; fix the tension assisting device on the side edge of the tower body through the clamping mechanism, ensuring that it is above the magnet; due to the existence of obstacles, when the steel ruler is used for long-distance measurement, a guiding block is sleeved on the steel ruler in advance; adsorb the guiding block on the tower body, bypass the obstacle, provide an intermediate support for the steel ruler, and assist the steel ruler to maintain a stable measurement form; the steel ruler extends towards the tension assisting device, is fixed to one end of the tensioner through a clamping piece, and the other end of the tensioner is hooked on the adjusting mechanism and is located on the sliding track; observe the reading of the tensioner, adjust the tension value of the steel ruler through the adjusting mechanism, and when the tension value reaches the specified value, read the length of the steel ruler at the measurement position, and this length is the true distance value between the two points bypassing the obstacle.

[0051] For example, if a tray needs to be installed on the tower body, a reference line is pre-drawn on the inner wall of the tower body, and the steel ruler is adsorbed on the reference line through a magnet respectively, and the tension assisting device is installed on the tray. Each time a position of the tray is measured, the tension is adjusted. After multiple measurements, it can be accurately judged whether there is an error in the installation position of the tray.

[0052] For another example, for a discontinuous tower body, the measurement distance may be long and the steel ruler is prone to shaking. Therefore, multiple guiding blocks are sleeved on the steel ruler and adsorbed at appropriate positions on the tower body respectively to ensure that the steel ruler is kept as horizontal as possible or close to the horizontal state during the measurement process. Repeat the above operation to obtain the true distance value bypassing the discontinuous break.
