DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a wall column verticality detection device, which is mainly used to detect the verticality deviation of the wall column. The verticality of the wall is one of the important indicators to measure the quality of the wall surface, which is of great significance to ensure the stability and aesthetics of the building. The traditional wall column verticality detection methods mainly include rulers, plumb bobs, total stations, theodolites, etc. According to different accuracy requirements and applicable scenarios, a suitable method is selected for detection. In view of the problems of low measurement efficiency, low measurement result accuracy and insufficient operation convenience in the prior art, this embodiment provides a wall column verticality detection device, which completes the verticality detection task of the wall column through the synergy between the components, and the device as a whole is easy to assemble and disassemble, which not only ensures the flexibility of measurement, but also can effectively improve the accuracy of the verticality measurement results.

[0022] like Figure 1-3 As shown, a wall column verticality detection device provided in this embodiment can be used to detect the verticality of a wall or column. In this embodiment, a wall is taken as an example. The detection includes a support frame 2, a lifting seat 3, a drive assembly 4, a rolling measurement assembly 5 and a marking assembly 6, wherein the support frame 2 includes a cross frame 21 and a support rod 23, etc., wherein the cross frame 21 is fixed to the top of the wall. During implementation, a suction cup can be fixedly installed on the cross frame to fix the cross frame on the wall to avoid damage to the wall (this structure is a prior art and will not be described in detail here). A positioning plate 25 is also formed vertically downward at the bottom of the cross frame to fit with the wall surface, so as to facilitate fixing the position of the cross frame.

[0023] The support rods 23 are installed at intervals along the vertical direction at the bottom of the horizontal frame. In this embodiment, the support rods are formed by threading multiple groups of guide rods. Specifically, the two ends of each guide rod are respectively provided with a plug-in portion and a sleeve portion, and the outer periphery of the plug-in portion and the inner wall of the sleeve portion are respectively threaded. In this embodiment, the plug-in portion is a threaded guide head 26. The threaded guide head 26 of one guide rod is threadedly sleeved with the sleeve portion of another guide rod. In this way, multiple groups of guide rods can be sleeved to form support rods of different lengths, which can be adaptively and flexibly adjusted according to different wall heights. Furthermore, the top of the topmost guide rod is threadedly connected to the horizontal frame and then fixed by a top screw, thereby strengthening the connection strength between the guide rod and the horizontal frame; the bottom of a guide rod in contact with the ground is a foot support seat 27, and a reinforcing rib is provided on the foot support seat, thereby effectively ensuring the stability and safety of the support frame during use.

[0024] like Figure 1 and 5 As shown, the lifting seat 3 is installed on the support rod along the vertical sliding direction, and can be lifted and slid along the support rod under the action of the driving component 4. Specifically, the lifting seat includes a sliding sleeve 31, a fixed seat 32 and a fixed rail 33, wherein the sliding sleeve is matched and sleeved on the support rod 23, the left and right sides of the fixed rail 33 are fixed on the sliding sleeve, and the fixed seat 32 is slidably sleeved on the fixed rail and can slide left and right along the extension direction of the fixed rail. After the position of the fixed seat is determined, it is locked by bolts.

[0025] The above-mentioned driving assembly can be a screw lift, a gear rack or other chain transmission structure, etc., which is used to control the lifting and sliding of the lifting seat on the support rod. This embodiment provides a driving assembly, such as Figure 1 and Figure 8 As shown, the drive assembly includes a wire rope 41, a handwheel 42, a worm 44, a worm wheel 45, a rope pulley 46, a first bevel gear 47 and a second bevel gear 48. A drive chamber 43 is symmetrically provided on the side of the sliding sleeve away from the fixed rail. A pair of mutually meshing bevel gears is provided in the drive chamber, wherein the rotating shaft of the first bevel gear is rotatably sleeved in a shaft seat 49, and the shaft seat is fixed in the drive chamber. A rope pulley 46 is fixedly installed at the end of the rotating shaft of the first bevel gear 47, and the wire rope 41 is matched and wound around the rope pulley. The output end of the wire rope extends vertically upward and is fixedly connected to the bottom of the guide sleeve 22 on the left and right sides of the cross frame.

[0026] The shaft of the second bevel gear 48 meshing with the first bevel gear is rotatably mounted on another shaft seat in the drive chamber, the worm gear 45 is fixedly mounted on the outer end of the shaft, the worm 44 is meshed with the worm gear, and the worm output shaft extends to the outside of the drive box and is connected to the handwheel 42. In addition, a lumen is opened in the interior of the fixed rail in the transverse direction, and a central shaft is mounted in the lumen. The left and right sides of the central shaft extend into the drive chambers on both sides and are connected to the shaft of the second bevel gear 48.

[0027] The drive assembly in this embodiment is arranged in such a way that when the handwheel on one side is driven, the rotating shaft on the second bevel gear on the other side can be synchronously driven to rotate through the central axis inside the fixed rail. Specifically, the worm is driven to rotate by the handwheel, and the worm is meshed with the worm wheel to drive the worm wheel and the second bevel gear 48 to rotate. The second bevel gear is meshed with the first bevel gear 47 to drive the rope pulley, so that the wire rope is wound around the rope pulley or loosened. That is, by driving the handwheel on one side to rotate, the rotation of the rope pulleys on both sides can be controlled at the same time, and then the extension or retraction of the wire ropes on both sides can be synchronously driven. Moreover, since the worm gear has a self-locking function, when the handwheel is stopped, the rope pulleys at both ends will not rotate autonomously, so that the position of the lifting seat can be limited in real time.

[0028] like Figure 4 and Figure 5 As shown, the rolling measurement assembly 5 includes a measuring roller 51, a connecting frame 52 and a measuring roller shaft 53, wherein the measuring roller is rotatably mounted on the connecting frame via the measuring roller shaft 53, and the measuring roller is parallel to the fixed rail 33 of the lifting seat and is in close contact with the wall surface, and the connecting frame 52 is mounted on the inner side of the fixed seat 32 of the lifting seat via the telescopic assembly 7, and the telescopic assembly 7 can enable the measuring roller to adaptively adjust the distance between the connecting frame and the fixed seat during the lifting process along the wall surface.

[0029] Further, see Figure 7 The telescopic assembly includes an elastic cavity 71, a spring 72 and a telescopic rod 73, wherein the elastic cavity is fixedly installed on the side of the fixing seat adjacent to the wall by bolts, the elastic cavity is hollow inside, and its opening faces the wall, a telescopic rod 73 is arranged inside the elastic cavity, and the extension direction of the telescopic rod is perpendicular to the fixed rail, and one end of the telescopic rod is fixed to the inner wall of the elastic cavity, and the other end extends outward and is fixedly connected to the connecting frame, and the spring is matched and sleeved outside the telescopic rod. In this way, when the measuring roller is lifted and lowered along the wall, if the wall is inclined, the extension amount of the telescopic rod can be automatically adjusted according to the change of the wall by pressing the spring, thereby driving the connecting frame and the measuring roller to move together, ensuring that the measuring roller always keeps close contact with the wall, and can automatically adapt to the change of the wall during the measurement process, thereby realizing the accurate measurement of the vertical change of the wall.

[0030] In order to facilitate the observation and calculation of the verticality deviation of the wall, this embodiment also provides a marking component 6, such as Figure 1As shown, the marking component in this embodiment includes a fixed laser detector 63 and a dynamic laser detector 64. An arc groove 24 is opened on the top surface of the cross frame. The fixed laser detector 63 is fixedly installed on the arc groove by a laser. The light beam output by the fixed laser detector passes vertically downward through the arc groove and is mapped to the top surface of the connecting frame 52. A center scale line is provided on the connecting frame. When the light beam of the fixed laser detector is emitted vertically downward, it can coincide with the center scale line on the connecting frame. The moving laser detector 64 is fixedly installed on one side of the connecting frame, and the light beam it emits is perpendicular to the light beam path of the fixed laser detector and coincides with the center scale line. When the measuring stick rolls along the wall, the measuring roller and the connecting frame automatically adapt to the changes in the wall through the telescopic assembly, thereby continuously performing telescopic movements, thereby driving the moving laser detector on the connecting frame to move back and forth. The staff records and observes the changes in the distance between the fixed laser detector 63 and the moving laser detector 64, and records and calculates the number of scales on the connecting frame, thereby realizing the detection of the verticality deviation of the wall. That is, during the measurement process, continuously observing whether the moving laser transmitter remains in the center position of the receiving groove scale line can realize the monitoring of the changes in the verticality of the wall column.

[0031] Description of working principle: When the wall column verticality detection device provided in this embodiment is used, the detection device is installed on the front side of the wall or column, and the support rod is spliced ​​and assembled according to the height adaptability of the wall; after the assembly is completed, the lifting seat is moved to the top or bottom, and then the hand wheel is turned, and the rope wheels on both sides of the fixed rail are synchronously driven to rotate through the transmission of the worm gear and the bevel gear, thereby controlling the retraction and release of the wire rope to realize the lifting and lowering of the lifting seat; at the same time, since the measuring roller is in close contact with the wall surface, when the lifting seat is lifted and lowered along the support rod, the measuring roller rolls on the wall surface, and automatically adapts to the changes in the wall surface through the telescopic component to ensure that the measuring roller is always in close contact with the wall surface; at the same time, the connecting frame can drive the moving laser detector to move, and the staff can judge the verticality deviation of the wall surface by observing and recording the changes in the distance between the fixed laser detector and the moving laser detector, as well as the number of scales on the connecting frame.

[0032] This embodiment provides an efficient, accurate, and easy-to-operate wall column verticality detection device, which realizes rapid adaptation and accurate detection of walls of different heights through the design of modular support frames, innovative drive components, adaptive rolling measurement components, and dual laser marking systems. The device is easy to operate and does not require punching holes or sticking marks on the wall. It effectively solves the problems of low efficiency, poor accuracy, and poor applicability of traditional detection methods, and greatly improves the efficiency and accuracy of wall column verticality detection.

[0033] Embodiment 2: Based on Embodiment 1, this embodiment provides another structure of a marking component (which can also be used in conjunction with the laser detector of Embodiment 1).

[0034] like Figure 4 and Figure 6 As shown, the marking assembly includes a fixed frame 61, a marking roller 62 and a marking pen 65, wherein the fixed frame 61 is fixedly mounted on the sliding sleeve below the connecting frame by a locking wire and can be raised and lowered synchronously with the sliding sleeve, and the marking pen 65 is vertically fixed to the bottom of the connecting frame, and the marking roller is rotatably mounted on the fixed frame 61 and is perpendicular to the fixed rail direction, and the lower end of the marking pen is in contact with the marking roller, and paper is fixedly attached to the marking roller, so that when the marking roller rotates, the marking pen can draw a circular track diagram on the paper on the marking roller. Figure 4 and 5 As shown, the marking roller is connected to the measuring roller through a transmission assembly. When the measuring roller rotates, the marking roller can be driven to rotate synchronously.

[0035] See also Figure 6 The transmission assembly includes a transmission box 81, a driving gear 82, a driven gear 83, a transmission shaft 84, a third bevel gear 85 and a fourth bevel gear 86, wherein one end of the rotating shaft 53 of the measuring roller extends into the transmission box and is connected to the driving gear, the driven gear is arranged below the driving gear and meshes with the driving gear for transmission; one end of the transmission shaft is fixedly sleeved in the driven gear, and the other end is connected to the third bevel gear 85 through the shaft frame, and the rotating shaft of the marking roller extends backward into the transmission box and is connected to the fourth bevel gear 86, and the fourth bevel gear meshes with the third bevel gear for transmission.

[0036] When the measuring roller rolls along the wall, the rotating shaft of the measuring roller can synchronously drive the driving gear to rotate. The driving gear is meshed with the driven gear to transmit the power, and the third bevel gear is rotated through its internal transmission shaft, and the marking roller is driven to rotate through meshing with the fourth bevel gear, so that the marking pen can draw the measuring roller moving along the wall to detect the verticality deviation of the wall. That is, if the wall is completely vertical, the trajectory expansion diagram drawn by the marking pen should be a straight line; if there is a verticality deviation of the wall, the expansion trajectory of the paper will appear wavy or inclined. By analyzing the trajectory diagram on the paper, the verticality deviation of the wall can be intuitively seen, and the degree of deviation of the trajectory reflects the magnitude of the verticality deviation.

[0037] Embodiment 3, based on Embodiments 1 and 2, this embodiment provides a wall column verticality detection method, which specifically includes the following steps: Step 1: Fix the horizontal frame to the top surface of the wall through the suction cup; install the detection device on the front side of the wall, adjust the position of the sliding sleeve and the measuring roller, and make the measuring roller close to the surface of the wall column; Step 2: Confirm that the beam of the fixed laser emitter is accurately projected onto the center scale line on the top surface of the connecting frame, and the beam of the dynamic laser emitter is parallel to the center scale line; Step 3: Turn the hand wheel to make the sliding sleeve drive the roller to roll upward along the wall surface. At the same time, the rotation of the roller is transmitted to the marking roller through the transmission assembly, so that the recording pen draws a continuous track line on the paper pasted on the marking roller; Step 4: During the measurement process, continue to observe whether the moving laser transmitter remains at the center position of the scale line of the connecting frame to monitor the change of the verticality of the wall column; every time the recording pen completes a circle of tracks on the marking roller, stop the hand wheel rotation and adjust the position of the paper on the marking roller; after completion, continue to move the sliding sleeve and the roller upwards, repeat the above rolling measurement and recording steps until the sliding sleeve moves to the top of the wall column; Step 5: When the sliding sleeve reaches the top of the wall column, stop turning the handwheel and end the measurement process; analyze the verticality deviation of the wall according to the position change of the dynamic laser transmitter in the receiving slot and the track line drawn by the recording pen on the marking roller; if the position of the dynamic laser transmitter deviates significantly from the center scale line, or the track line is obviously tilted, it indicates that the verticality of the wall column does not meet the requirements; the above detection steps can be repeated multiple times.

[0038] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to detect the verticality of wall columns by combining mechanical rolling measurement and laser projection. Laser projection monitors the overall inclination through fixed laser and dynamic laser transmitters. Mechanical rolling measurement records the wall profile through measuring rollers and marking rollers to achieve more accurate detection and recording of wall inclination deviations. Continuous trajectory lines are drawn by marking rollers and recording pens to achieve continuous recording of the verticality of the entire wall, which can intuitively show the changing trend of the verticality of the wall. The device is suitable for various types of wall columns, and the measurement method is highly versatile. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.

The positioning frame is fixedly installed on the sliding sleeve below the connecting frame and can move up and down synchronously with the sliding sleeve. The marking roller is perpendicular to the direction of the fixed rail and is rotatably installed on the positioning frame. The lower end of the recording pen is in contact with the marking roller. The marking roller is connected to the rotating roller through the transmission assembly. When the rotating roller rotates, it can synchronously drive the rotation of the marking roller.

10. A method for detecting the verticality of a wall column, using the device for detecting the verticality of a wall column according to claims 1 to 9, characterized in that: The following steps are involved: Step 1: Fix the beam on the top surface of the wall column through the suction cup; install the detection device on the front side of the wall column, adjust the position of the sliding sleeve and the roller, and make the roller close to the surface of the wall column; Step 2: Confirm that the beam of the fixed laser transmitter is accurately projected into the receiving slot on the top surface of the connecting frame and overlaps with the beam of the dynamic laser transmitter; Step 3: Turn the hand wheel to make the sliding sleeve drive the roller to roll upward along the surface of the wall column. At the same time, the rotation of the roller is transmitted to the marking roller through the transmission assembly, so that the recording pen draws a continuous track line on the paper pasted on the marking roller; Step 4: During the measurement process, continue to observe whether the moving laser transmitter remains at the center position of the receiving slot scale line to monitor the change in the verticality of the wall column; every time the recording pen completes a circle of tracks on the marking roller, stop the hand wheel rotation and adjust the position of the paper on the marking roller; after completion, continue to move the sliding sleeve and the roller upwards, repeat the above rolling measurement and recording steps until the sliding sleeve moves to the top of the wall column; Step 5: When the sliding sleeve reaches the top of the wall column, stop turning the hand wheel and end the measurement process; analyze the verticality deviation of the wall column according to the position change of the dynamic laser transmitter in the receiving slot and the track line drawn by the recording pen on the marking roller; If the position of the moving laser transmitter deviates significantly from the center scale line, or the trajectory line is obviously tilted, it indicates that the verticality of the wall column does not meet the requirements; the above detection steps can be repeated multiple times.
