Description

Technical Field

[0001] The present invention relates to the technical field of detecting the flatness of masonry walls, and specifically provides a detecting device for the perpendicularity and flatness of masonry structures. Background Art

[0002] In the field of building construction, the perpendicularity and flatness of the surface of a masonry wall are key indicators for measuring the construction quality of the wall, directly affecting the subsequent decoration project, as well as the overall safety and aesthetics of the building.

[0003] Currently, the detection of the perpendicularity and flatness of the surface of existing masonry walls mainly relies on manual labor. Workers need to use simple tools such as straightedges to measure and compare point by point and section by section. This traditional detection method has many drawbacks. On the one hand, the labor intensity is extremely high. The inspectors need to hold the tools for a long time and repeatedly perform measurement operations. Especially when detecting large-area walls, it not only consumes a large amount of manpower and time, but also easily causes fatigue of the inspectors, thereby affecting work efficiency. On the other hand, the accuracy of manual detection is relatively low. Due to the influence of human factors during the measurement process, such as improper placement of the straightedge and reading errors, the reliability of the detection results is greatly reduced, making it difficult to meet the requirements of high-precision quality control in modern building construction.

[0004] Although there are also some cases in the market where equipment is used to detect the perpendicularity and flatness of walls, these detection devices also face some problems during actual use. Many detection devices need to be installed on the ground for operation. However, the ground conditions at the construction site are complex and changeable, and there are often soft areas. When the equipment is installed on soft ground, its stability cannot be effectively guaranteed, and it is prone to tilting. Once the equipment tilts, the detection reference will deviate, resulting in the detection data not conforming to the actual wall situation, ultimately causing a decrease in detection accuracy and being unable to accurately reflect the true perpendicularity and flatness of the wall, bringing great trouble to the quality assessment of the wall.

[0005] In summary, the existing wall detection methods have obvious deficiencies, and there is an urgent need for a new type of wall perpendicularity and flatness detection technology or equipment that can improve detection accuracy, reduce labor intensity, and is not affected by ground conditions.

[0017] The embodiments of the present invention have the following advantages.

[0018] When detecting the perpendicularity and flatness of masonry, the fixing plate is fixed on the top surface of the masonry through the fixture mechanism, so that the fixing plate is arranged along the extending direction of the top end of the masonry. For the two transverse servo slide rail assemblies, the length direction is consistent with the length direction of the fixing plate. During the detection process, the longitudinal servo slide rail assembly is started, so that the longitudinal servo slide rail assembly drives the probe detection unit to be at the top or bottom of the masonry. The probe assemblies installed on the two longitudinal servo slide rail assemblies are driven by the transverse servo slide rail assembly, driving the two longitudinal servo slide rail assemblies to reciprocate along the transverse servo slide rail assembly, so that the probe detection unit moves horizontally along the surface of the masonry. When the probe detection unit moves to one end of the masonry, the longitudinal servo slide rail assembly is started, so that the longitudinal servo slide rail assembly drives the probe detection unit to move downward by a certain distance. Then the transverse servo slide rail assembly is started again to drive the longitudinal servo slide rail assembly and the probe detection unit to move in the opposite direction. Repeat the above steps, so that the transverse servo slide rail assembly and the longitudinal servo slide rail assembly drive the probe detection unit to move in a serpentine trajectory on the surface of the masonry, and then the flatness of the masonry in the horizontal direction can be detected by this moving method.

[0019] Furthermore, through the cooperation of the transverse servo slide rail assembly and the longitudinal servo slide rail assembly, when started simultaneously, it can drive the probe detection unit to move from one corner of the masonry to the other corner on the surface of the masonry, so that the probe detection unit moves along the diagonal of the masonry, and can detect the dislocation of local bricks and the diagonal distortion of the masonry, identify the diagonal warping of the wall, and realize the detection of the diamond deformation of the masonry.

[0020] Furthermore, when detecting the perpendicularity of the masonry, start the transverse servo slide rail assembly to drive the two longitudinal servo slide rail assemblies to move to one side edge of the masonry, and drive the probe detection unit to move to the top or bottom of the masonry through the longitudinal servo slide rail assembly. The transverse servo slide rail assembly fixes the position of the longitudinal servo slide rail assembly, and starts the longitudinal servo slide rail assembly to drive the probe detection unit to move vertically along the surface of the masonry. When the probe detection unit moves to the other end, start the transverse servo slide rail assembly to drive the longitudinal servo slide rail assembly and the probe detection unit to move horizontally by a certain distance, and then start the longitudinal servo slide rail assembly to drive the probe detection unit to move, so that the probe detection unit moves in a serpentine trajectory vertically along the surface of the masonry, and realizes the detection of the perpendicularity of each position on the surface of the masonry.

[0021] In this embodiment, the transverse servo slide rail assembly and the longitudinal servo slide rail assembly are fixed on both side surfaces of the masonry through the fixing plate. Compared with fixing the detection equipment fixing structure on the ground, it can improve the problem that the ground is soft and easily causes the fixing structure to tilt, reduce the problem of the probe shaking during the moving process, and reduce the influence of wind force on the stability of the fixing structure.

[0022] Meanwhile, the servo system ensures the accuracy and repeatability of the moving speed and path of the probe detection unit, eliminates the speed fluctuations and trajectory deviations of manually pushing the straightedge, and with the same set of probe detection units, different paths (horizontal serpentine, vertical serpentine, diagonal) planned by the transverse servo slide rail assembly and the longitudinal servo slide rail assembly can automatically complete the detection of three key indicators, namely flatness (horizontal direction), perpendicularity, and diagonal deformation (rhombic deformation) after a single installation, without the need to replace equipment or tools.

[0023] The probe detection unit consists of a detection head and a cylinder telescoping system. The cylinder telescoping system is used to inflate and deflate one end of the probe, enabling the detection head to automatically retract or extend during the process of encountering the depressions and protrusions on the surface of the masonry. Subsequently, the structural drawing of the masonry surface can be drawn by recording the telescoping situation of the detection head, enabling it to adapt to the unevenness of the wall surface, maintain contact during movement, and measure the telescoping amount in real time, directly reflecting the true undulating contour of the wall surface, and being less sensitive to floating ash than non-contact lasers.

[0024] The entire detection process (except for installation) is automatically scanned and moved by the servo system, significantly reducing the time and falling risk for the detection personnel to repeatedly move and operate equipment at high altitudes or on scaffolds. The mechanized servo control ensures that the moving path, speed, and coverage range of each detection are highly consistent, making the detection data traceable and reproducible, and reducing the subjective errors of manual operations.

[0056] The following combines Figures 1 to 7 to describe the technical solution of the present invention:

[0057] The embodiment of the present invention provides a detection device for the perpendicularity and flatness of masonry. The detection device includes: a fixing plate 100 installed on the top surface of the masonry, and the fixing plate 100 is arranged along the extending direction of the masonry; a fixture mechanism 200 disposed on the bottom surface of the fixing plate 100, and the fixture mechanism 200 is connected to the masonry in a clamping manner; a transverse servo slide rail assembly 300 symmetrically disposed on both sides of the fixing plate 100 and arranged along the length direction of the fixing plate 100; a longitudinal servo slide rail assembly 400 vertically arranged, with the top end connected to the transverse servo slide rail assembly 300; a probe detection unit 500 disposed on the longitudinal servo slide rail assembly 400; wherein the probe detection unit 500 includes: a detection head 510 that can expand and contract in the horizontal direction, and a cylinder expansion and contraction system 520, and the detection head 510 is slidably disposed at the output end of the cylinder expansion and contraction system 520.

[0058] In the above embodiments, when detecting the perpendicularity and flatness of the masonry, the fixing plate 100 is fixed on the top surface of the masonry through the fixture mechanism 200, so that the fixing plate 100 is arranged along the extending direction of the top end of the masonry. The length directions of the two transverse servo slide rail assemblies 300 are kept consistent with the length direction of the fixing plate 100. During the detection process, the longitudinal servo slide rail assembly 400 is started, so that the longitudinal servo slide rail assembly 400 drives the probe detection unit 500 to be at the top or bottom end of the masonry. The probe detection units 500 installed on the two longitudinal servo slide rail assemblies 400 are driven by the transverse servo slide rail assembly 300, driving the two longitudinal servo slide rail assemblies 400 to reciprocate along the transverse servo slide rail assembly 300, so that the probe detection unit 500 moves horizontally along the surface of the masonry. When the probe detection unit 500 moves to one end of the masonry, the longitudinal servo slide rail assembly 400 is started, so that the longitudinal servo slide rail assembly 400 drives the probe detection unit 500 to move downward by a certain distance. Then the transverse servo slide rail assembly 300 is started again to drive the longitudinal servo slide rail assembly 400 and the probe detection unit 500 to move in the opposite direction. The above steps are repeated, so that the transverse servo slide rail assembly 300 and the longitudinal servo slide rail assembly 400 drive the probe detection unit 500 to move in a serpentine trajectory on the surface of the masonry, and then the flatness of the masonry in the horizontal direction can be detected by this moving method.

[0059] Furthermore, through the cooperation of the transverse servo slide rail assembly 300 and the longitudinal servo slide rail assembly 400, when started simultaneously, they can drive the probe detection unit 500 to move from one top corner of the masonry to the other top corner on the surface of the masonry, so that the probe detection unit 500 moves along the diagonal of the masonry, and the local brick dislocation and diagonal distortion of the masonry can be detected, and the diagonal warping of the wall can be identified to realize the detection of the diamond deformation of the masonry.

[0060] Furthermore, when detecting the perpendicularity of the masonry, the transverse servo slide rail assembly 300 is started to drive the two longitudinal servo slide rail assemblies 400 to move to one side edge of the masonry, and the longitudinal servo slide rail assembly 400 is used to drive the probe detection unit 500 to move to the top or bottom end of the masonry. The transverse servo slide rail assembly 300 fixes the position of the longitudinal servo slide rail assembly 400, and the longitudinal servo slide rail assembly 400 is started to drive the probe detection unit 500 to move vertically on the surface of the masonry. When the probe detection unit 500 moves to the other end, the transverse servo slide rail assembly 300 is started to drive the longitudinal servo slide rail assembly 400 and the probe detection unit 500 to move horizontally by a certain distance. Then the longitudinal servo slide rail assembly 400 is started again to drive the probe detection unit 500 to move, so that the probe detection unit 500 moves in a serpentine trajectory vertically on the surface of the masonry, realizing the detection of the perpendicularity of each position on the surface of the masonry.

[0061] In this embodiment, the transverse servo slide rail assembly 300 and the longitudinal servo slide rail assembly 400 are fixed on both side surfaces of the masonry through the fixing plate 100. Compared with fixing the detection device structure on the ground, it can improve the problem that the fixing structure is prone to tilt due to soft ground, reduce the problem of jitter during the movement of the probe, and reduce the influence of wind force on the stability of the fixing structure.

[0062] At the same time, the servo system ensures the accuracy and repeatability of the moving speed and path of the probe detection unit 500, eliminates the speed fluctuation and trajectory deviation of manually pushing the straightedge. With the same set of probe detection unit 500, different paths (horizontal snake-shaped, vertical snake-shaped, diagonal) planned by the transverse servo slide rail assembly 300 and the longitudinal servo slide rail assembly 400 can automatically complete the detection of three key indicators: flatness (in the horizontal direction), verticality, and diagonal deformation (rhombic deformation) after a single installation, without the need to replace equipment or tools.

[0063] The probe detection unit 500 is composed of a detection head 510 and a cylinder telescopic system 520. The cylinder telescopic system 520 is used to inflate and deflate one end of the probe, so that the detection head 510 can automatically retract or extend during the process of encountering the depression and protrusion on the surface of the masonry. Then, by recording the telescopic situation of the detection head 510, a structural drawing of the surface of the masonry can be drawn, enabling it to adapt to the unevenness of the wall surface, maintain contact and measure the telescopic amount in real time during the movement, directly reflect the true undulating contour of the wall surface, and be less sensitive to floating ash than non-contact lasers.

[0064] The entire detection process (except for installation) is automatically completed by the servo system for scanning and moving, significantly reducing the time and falling risk of the detection personnel moving and operating equipment repeatedly at high altitude or on scaffolds. The mechanized servo control ensures that the moving path, speed, and coverage range of each detection are highly consistent, making the detection data traceable and reproducible, and reducing the subjective error of manual operation.

[0065] Please refer to Figures 1 - 7, in some embodiments, a plurality of fixture mechanisms 200 are arranged at intervals along the length direction of the bottom surface of the fixing plate 100; wherein the fixture mechanism 200 includes: a limiting square tube 210, arranged on the bottom surface of the fixing plate 100, and the length direction of the limiting square tube 210 is perpendicular to the length direction of the fixing plate 100; a first slide rail 220, arranged on the inner wall of the limiting square tube 210; first sliders 230, symmetrically arranged in the limiting square tube 210, and two groups of the first sliders 230 are slidably connected to the first slide rail 220; inclined grooves 240, arranged on the adjacent surfaces of the two groups of the first sliders 230; a second slider 250, with both ends slidably connected to the two groups of the inclined grooves 240; a sliding hole 260, arranged on the bottom surface of the limiting square tube 210 along the length direction of the limiting square tube 210; clamping heads 270, arranged on the bottom surface of the first sliders 230, and the two groups of the clamping heads 270 are used to clamp the outer walls on both sides of the top of the masonry; a threaded rod 280, with the bottom end passing through the top surface of the limiting square tube 210 and rotatably connected to the top surface of the second slider 250, and the outer circumferential wall is threadedly connected to the top surface of the limiting square tube 210.

[0066] In the above embodiments, the limiting square tube 210 is arranged on the bottom surface of the fixing plate 100 and is used for slidingly limiting the first sliders 230. When installing the fixing plate 100, place the fixing plate 100 on the top surface of the masonry, and then rotate the threaded rod 280, so that the threaded rod 280 drives the second slider 250 to move upward. The inclined grooves 240 of the two groups of the first sliders 230 are V-shaped. By driving the two groups of the first sliders 230 to move closer to the center through the second slider 250, the two groups of the second sliders 250 drive the two groups of the clamping heads 270 to move closer, so that the two groups of the clamping heads 270 clamp the outer walls on both sides of the top of the masonry. Fix the fixing plate 100 through a plurality of fixture mechanisms 200, and reduce the jitter problem during the movement of the transverse servo slide rail assembly 300 and the longitudinal servo slide rail assembly 400 installed on both sides of the fixing plate 100.

[0067] By rotating a single threaded rod 280 to drive the vertical movement of the second slider 250, and using the V-shaped inclined plane structure of the inclined groove 240, synchronously drive the two groups of the first sliders 230 to slide towards each other along the first slide rail 220, so as to quickly clamp the top of the masonry by the two groups of the clamping heads 270 on both sides. It improves the traditional fixture that needs to be adjusted one by one. This design realizes single-point operation to complete bilateral synchronous fixation, significantly improves the installation efficiency. The limiting square tube 210 eliminates the micro-displacement of the fixing plate 100 caused by the loosening of the fixture, ensures that there is no jitter when the transverse servo slide rail assembly 300 and the longitudinal servo slide rail assembly 400 move. Each group of the clamping heads 270 is connected through an independent first slider 230, and can adapt to the irregular contour of the top surface of the masonry (such as local protrusions / depressions), ensuring uniform distribution of the clamping force.

[0068] Please refer to Figures 1 - 7, in some embodiments, the lateral servo slide rail assembly 300 includes: two second slide rails 310 disposed on both side surfaces of the fixed plate 100, the length direction of the two second slide rails 310 being parallel to the length direction of the fixed plate 100; a third slider 320 slidably disposed on the side of the second slide rail 310 away from the fixed plate 100; and a horizontal adjustment rod 330 disposed on the side of the third slider 320 away from the second slide rail 310, the top end of the longitudinal servo slide rail assembly 400 sliding along the length direction of the horizontal adjustment rod 330.

[0069] In the above embodiment, the second slide rail 310 is used to limit the sliding of the third slider 320, and at the same time, the third slider 320 is driven to slide on the second slide rail 310 by a servo motor and a transmission mechanism.

[0070] Furthermore, in order to adjust the distance between the two longitudinal servo slide rail assemblies 400 so that the distances between the two probe detection units 500 and the outer walls on both sides of the masonry can be adjusted to adapt to the thicknesses of masonries of various specifications, by pushing the top end of the longitudinal servo slide rail assembly 400 to slide on the horizontal adjustment rod 330 and fixing the longitudinal servo slide rail assembly 400 through a locking mechanism. The locking mechanism that can be adopted includes a fastening bolt penetrating the outer wall of the top end of the longitudinal servo slide rail assembly 400, and the fastening bolt is threadedly connected to the mounting hole on the longitudinal servo slide rail assembly 400, so that the fastening bolt can pass through the mounting hole and abut against the outer circumferential wall of the horizontal adjustment rod 330, and the longitudinal servo slide rail assembly 400 is limited in sliding by the fastening bolt to achieve the locking effect.

[0071] Please refer to Figures 1 - 7 , in some embodiments, the longitudinal servo slide rail assembly 400 includes: a third slide rail 410, the top end of which is sleeved on the outer circumferential wall of the horizontal adjustment rod 330; a fourth slider 420 slidably disposed on the surface of the third slide rail 410; and the probe detection unit 500 is mounted on the fourth slider 420.

[0072] In the above embodiment, the top end of the third slide rail 410 is sleeved on the outer circumferential wall of the horizontal adjustment rod 330, so that the longitudinal servo slide rail assembly 400 can slide on the horizontal adjustment rod 330 to realize the adjustment of the distance between the probe detection units 500.

[0073] Please refer to Figures 1 - 7, in some embodiments, the probe detection unit 500 further includes: a first motor 530 installed on the fourth slider 420, and the output shaft of the first motor 530 passes through the fourth slider 420; a mounting plate 540 installed on the output shaft of the first motor 530; a plurality of cylinder expansion and contraction systems 520 are provided, and the plurality of cylinder expansion and contraction systems 520 are arranged at intervals along the mounting plate 540; a cleaning unit 550 and the probe detection unit 500 are respectively installed on each of the cylinder expansion and contraction systems 520.

[0074] In the above embodiments, the first motor 530 is installed on the fourth slider 420, and the fourth slider 420 slides on the third slide rail 410, driving the first motor 530 and the mounting plate 540 to move. When the probe detection unit 500 needs to switch from reciprocating movement in the horizontal direction to reciprocating movement in the vertical direction, the first motor 530 is started to drive the mounting plate 540 to rotate by ninety degrees, so that the mounting plate 540 drives each cylinder expansion and contraction system 520 to turn, and then drives the connection line of the cleaning unit 550 and the probe detection unit 500 to rotate through the turning of the cylinder expansion and contraction system 520.

[0075] Please refer to Figures 1 - 7 , in some embodiments, the cylinder expansion and contraction system 520 includes: a sleeve 521 installed on the side of the mounting plate 540 close to the masonry; a working chamber 522 provided on the inner wall of the sleeve 521, the working chamber 522 is annular, and the working chamber 522 is concentrically arranged with the sleeve 521; a piston plate 523 slidably arranged in the working chamber 522; wherein one side of the piston plate 523 close to the masonry is connected to the cleaning unit 550 or the probe detection unit 500; an air inlet hole 524 and an air outlet hole 525 are provided through the circumferential outer wall of the sleeve 521, and the air inlet hole 524 and the air outlet hole 525 are respectively connected to an air inflation pump and an air extraction pump.

[0076] In the above embodiments, the cylinder telescopic system 520 is used to drive the probe detection unit 500 or the cleaning unit 550 to move when the piston plate 523 moves. When the probe detection unit 500 moves on the masonry surface, the air in the working chamber 522 is extracted by the air extraction pump, so that the piston plate 523 moves in the working chamber 522, and the piston plate 523 drives the cleaning unit 550 and the probe detection unit 500 to retract and abut against the masonry surface. Subsequently, the working chamber 522 is inflated by the air inflation pump to maintain the pressure in the working chamber 522. When the probe detection unit 500 encounters a deep depression on the masonry surface, the air in the working chamber 522 pushes the piston plate 523 to drive the detection end of the probe detection unit 500 to extend into the depression. When moving in the depression, if the inner wall edge of the depression is nearly parallel to the length direction of the probe, the air in the working chamber 522 is extracted by the air extraction pump to retract the probe detection unit 500, so as to avoid that when the probe detection unit 500 moves, it pushes the bricks and causes the bricks to displace, resulting in the damage of the integrity of the masonry. If a brick protrusion with an oversize outward extension is encountered, to avoid the probe detection unit 500 pushing the brick to move, the air in the working chamber 522 can also be extracted by the air extraction pump to retract the probe detection unit 500 to avoid obstacles.

[0077] Please refer to Figures 1 - 7 , in some embodiments, the probe detection unit 500 includes: a probe rod 511, the middle section of which is arranged in the working chamber 522, one end is arranged close to the masonry surface, and the other end passes through the mounting plate 540; wherein the probe rod 511 passes through the piston plate 523; the probe detection unit 500 further includes: a laser rangefinder 560, arranged on the side of the mounting plate 540 away from the sleeve 521, and the laser rangefinder 560 is arranged on one side of the circumferential outer wall of the probe rod 511; a reflector 570, arranged on the end wall of the probe rod 511 close to the laser rangefinder 560; a light-shielding cylinder 580, sleeved on the circumferential outer wall of the reflector 570, and one end of the light-shielding cylinder 580 away from the reflector 570 is connected to the surface of the mounting plate 540.

[0078] In the above embodiments, one end of the probe rod 511 is a detection end, which is arranged close to the surface of the masonry. The other end is an installation end, which passes through the piston plate 523 and the mounting plate 540. The installation end slides on the surface of the mounting plate 540. The mounting plate 540 is sealed with one end of the sleeve 521. When the probe rod 511 encounters a protrusion on the surface of the masonry, the probe rod 511 retracts, and the detection end moves along the surface of the protrusion. The installation end moves in the direction away from the masonry. During the movement, the installation end of the probe rod 511 drives the reflector 570 to move. The laser emitter of the laser rangefinder 560 emits laser light in the direction of the reflector 570. The laser light is reflected by the reflector 570 and the reflected laser light is received by the receiver of the laser rangefinder 560. The movement distance of the reflector 570 is detected by the laser rangefinder 560, and then the movement of the probe rod 511 when encountering a depression or a protrusion can be counted, and the sizes of the depressions and protrusions on the surface of the masonry can be counted.

[0079] Please refer to Figures 1 - 7 , in some embodiments, the probe detection unit 500 further includes: a roller 512, mounted at one end of the probe rod 511 close to the masonry; a mounting groove 513, provided at one end of the probe rod 511 close to the masonry, and the roller 512 is rotatably mounted in the mounting groove 513; a hemispherical surface 514, provided at one end of the probe rod 511 close to the masonry, and the mounting groove 513 is opened at one end of the hemispherical surface 514 away from the probe rod 511; a strip groove 515, arranged along the surfaces of the probe rod 511 and the hemispherical surface 514; wherein the length direction of the strip groove 515 is arranged along the length direction of the probe rod 511, and a plurality of the strip grooves 515 are provided, and the plurality of strip grooves 515 are arranged at equal intervals on one side surface of the probe rod 511; a strip switch 516, provided in each strip groove 515, and the strip switch 516 is connected to the power supply of the air extraction pump.

[0080] In the above embodiments, the hemispherical surface 514 cooperates with the roller 512 for walking on the surface of the masonry. The roller 512 is used to reduce the friction with the surface of the masonry. When the conical roller 512 moves in the mortar joint, it can move along the mortar joint, and then the inclination of the mortar joint can be detected by the conical roller 512.

[0081] A strip switch 516 is arranged in the strip groove 515. The flexible long strip-shaped outer shell (such as rubber or silica gel) has a long strip-shaped conductive rubber strip or metal spring piece embedded inside. Below is a PCB substrate with two parallel long strip electrodes on it. When not pressed, the conductive strip does not contact the electrodes and the circuit is open. When pressed at any position, the conductive strip deforms and contacts the two electrodes below simultaneously to achieve short circuit. When the probe rod 511 encounters a shallow depression, the probe rod 511 can slide out of the depression through the hemispherical surface 514. However, when encountering a deeper depression, continuous movement will cause the probe rod 511 to push the brick to displace. When encountering the inner wall of a deeper depression, the movement of the probe rod 511 will cause the strip switch 516 to contact the inner wall of the depression, and the inner wall of the depression squeezes the strip switch 516, causing the strip switch 516 to trigger and start the air extraction pump to extract air urgently, so that the probe rod 511 can be quickly recovered.

[0082] Please refer to Figures 1 - 7 , in some embodiments, a flushing hole 517 is provided on the axis of the probe rod 511. Both ends of the flushing hole 517 penetrate through the end wall of the probe rod 511. One end of the flushing hole 517 penetrates through the inner wall of the installation groove 513, and the other end is used for pipe connection to a water pump.

[0083] When the probe rod 511 moves from one end to the other on the surface of the masonry, the water pump is started, and the cleaning water is pumped into the flushing hole 517 of the probe rod 511, so that the flushing water enters the installation groove 513 through the flushing hole 517, and the roller 512 in the installation groove 513 is flushed through the high-pressure water flow, thereby achieving the effect of cleaning the roller 512 and avoiding the problem that the mortar blocks the installation groove 513, resulting in the roller 512 being unable to rotate normally and increasing the friction between the roller 512 and the surface of the masonry.

[0084] Please refer to Figures 1 - 7 , in some embodiments, the cleaning unit 550 includes: a cleaning rod 551 arranged in the working cavity 522; a second motor 552 arranged at one end of the cleaning rod 551 close to the surface of the masonry, and the output shaft of the second motor 552 is oriented towards the surface of the masonry; and a brush head 553 arranged on the output shaft of the second motor 552.

[0085] In the above embodiments, the cleaning rod 551 moves in the same way as the probe rod 511. Air is filled into the working cavity 522 through an air pump, so that the probe rod 511 and the cleaning rod 551 can be recovered when encountering obstacles and can be reset to abut against the surface of the masonry when passing through obstacles. The second motor 552 arranged at the end of the cleaning rod 551 is started to drive the brush head 553 to rotate. The brush head 553 is arranged in the front of the moving direction of the probe rod 511. The surface of the masonry is first cleaned by the brush head 553, and then the roller 512 of the probe rod 511 moves on the cleaned surface of the masonry, avoiding mortar and sand from entering the installation groove 513.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
