Through systematic measurement and detection, the construction quality of the wall can be guaranteed from multiple dimensions such as structural safety, function realization and specification compliance, thereby laying a foundation for long-term safe use and aesthetics of the building.

[0004] However, the existing wall measuring device for building construction has the following disadvantages:

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] The present application is directed to a built-in double-layer wall for partition, and in view of different measurement items, the traditional method needs to use different measuring instruments and manual operation, and due to low integration, multiple data collection cannot be performed simultaneously, resulting in low efficiency and long time consumption.

[0037] The traditional measurement method adopts a mode combining instrument measurement and manual operation, and the measuring equipment used has low integration degree, cannot realize simultaneous measurement of multiple items, and needs to complete each data collection one by one, especially when facing double-sided interior walls, the workload increases dramatically.

[0039] Please refer to Figures 1-2 and Figure 8 The application provides a technical solution: a wall measuring device for building construction, which comprises a centralized long plate 1, a symmetrical lifting assembly 400, a joint scanning assembly 500 and a joint mechanical assembly 600, the symmetrical lifting assembly 400 is located on the front of the centralized long plate 1, the joint scanning assembly 500 is located below the symmetrical lifting assembly 400, the joint mechanical assembly 600 is installed on the front of the centralized long plate 1, the front and back of the centralized long plate 1 are respectively provided with a set of main slide rails 2 and auxiliary slide rails 3, the first external bracket 416 is connected with spliced plates 7 on both sides, the outer walls of the two spliced plates 7 are respectively provided with a power storage assembly 8 and an electric control box 9, the surface of the electric control box 9 is electrically connected with an embedded screen 10, and the power storage assembly 8 and the electric control box 9 are electrically connected with the centralized long plate 1.

[0040] In some embodiments, as Figure 4 and Figure 8As shown, the symmetrical lifting assembly 400 comprises two solid bases 403, the front surface of each solid base 403 is provided with an expansion roller 410 for driving the equipment to move vertically on the wall, the symmetrical lifting assembly 400 also comprises two groups of first sliding sleeves 401, each first sliding sleeve 401 is respectively in sliding connection with a corresponding main sliding rail 2, the front surfaces of each group of first sliding sleeves 401 are connected with a combined lining plate 402, each solid base 403 is connected with a corresponding combined lining plate 402, the inside of each solid base 403 is inserted with a first motor driving piece 404, the outer side surface of each solid base 403 is connected with a first outer frame 405, the center of each first outer frame 405 is connected with a coupling 406, the shaft end of each first motor driving piece 404 is connected with the end of a corresponding coupling 406, the outer wall of each first outer frame 405 is connected with a second outer frame 407, the center of each second outer frame 407 is connected with a roller bearing 408, the inner shaft inner wall of each roller bearing 408 is inserted with a transmission rod 409, the end of each transmission rod 409 is connected with the front end of a corresponding coupling 406, each expansion roller 410 is fixedly sleeved at the front end of the transmission rod 409, the outer wall of each expansion roller 410 is wrapped with a convex tooth rubber wheel sleeve 411, the upper and lower ends of each solid base 403 are connected with a linkage support arm 412, the surface of each linkage support arm 412 is assembled with a clamp sleeve 413, the inside of each clamp sleeve 413 is connected with a second sliding sleeve 414, each second sliding sleeve 414 is respectively in sliding connection with a corresponding auxiliary sliding rail 3, the ends of the two second sliding sleeves 414 are connected with a row of teeth piece 415, the two row of teeth pieces 415 are placed in opposite intersection, the back of the cable collecting plate 1 is connected with a first external bracket 416, the center of the first external bracket 416 is installed with a second motor driving piece 417, the shaft end of the second motor driving piece 417 is sleeved with a driving gear 418, the driving gear 418 is in meshing connection with the two row of teeth pieces 415.

[0041] In use, before the device starts running, a leveling test needs to be carried out first to check whether the power in the power storage assembly 8 is sufficient, so as to avoid the device from falling due to power interruption during use. During the test, the device is inserted horizontally from the side of the double-layer wall, and the side supporting plate 602 is ensured to be close to the side of the wall. The second motor drive 417 is turned on to drive the driving gear 418 at a uniform speed. The meshing connection between the gear teeth 415 and the driving gear 418 and the sliding connection between the auxiliary slide rail 3 and the second slide sleeve 414 enable the two gear teeth 415 to retract synchronously. Under the traction of the linkage arm 412, the first slide sleeve 401 connected to the main slide rail 2 will synchronously drive the two expansion rollers 410 to move relatively, continuously reducing the distance between them, until the convex tooth rubber wheel sleeve 411 on the two expansion rollers 410 is close to the two sides of the wall. Then the two first motor drives 404 are turned on to act on the transmission rod 409, driving the two expansion rollers 410 connected thereto to rotate relatively, so as to drive the device main body to rise slowly along the side of the wall. The relevant personnel observe the close condition of the convex tooth rubber wheel sleeve 411 in the path during the movement of the device. If the expansion rollers 410 are raised in multiple places, it indicates that the wall surface in the path range is not flat, and the convex points in the path need to be processed first to avoid affecting the subsequent flatness detection. The two expansion rollers 410 are driven by the first motor drive 404 to rotate away from each other, so that the device moves to the bottom end of the wall.

[0042] In a more optimized scheme, as shown in Figure 8 , the outer surface of the first external bracket 416 is connected with two third external brackets 419. A pneumatic push rod 420 is inserted at the center of each third external bracket 419. The shaft end of each pneumatic push rod 420 is sleeved with a locking piece 421.

[0043] In use, when the two convex tooth rubber wheel sleeves 411 are fully close to the two sides of the wall, the pneumatic push rod 420 is turned on, and the inner shaft extends outward to drive the locking piece 421 to press down, as shown in Figure 4 . Finally, the locking piece 421 acts on the two gear teeth 415. Since the locking piece 421 is made of rubber, the pressing force and the friction between the locking piece 421 and the surface of the gear teeth 415 prevent the gear teeth 415 from shifting and prevent the convex tooth rubber wheel sleeve 411 from loosening, which can cause the device to fall.

[0044] In some embodiments, as shown in Figure 3 and Figure 5As shown, the joint scanning assembly 500 comprises two face plates 502, each of which is flush with one side of the corresponding expansion roller 410, and the associated frame 501 is used to fit the wall surface, and each face plate 502 is additionally provided with an exciter 503 on the outer wall, and each exciter 503 is electrically connected to a group of emission heads 504, and each group of emission heads 504 is flush with the front end of the corresponding face plate 502, and the joint scanning assembly 500 further comprises two associated frames 501, and the end of each associated frame 501 is connected to the inner side of the corresponding solid base 403, and each face plate 502 is connected to the corresponding associated frame 501, and each exciter 503 is additionally provided with a receiver 505 on the outer wall, and the front end of each receiver 505 is electrically connected to a reflective window 506, and the inner side of each face plate 502 is connected to a microprocessor 507, and each receiver 505 is electrically connected to the corresponding microprocessor 507, and the output end of each microprocessor 507 is electrically connected to a visual screen 508.

[0045] In use, since the face plate 502 is flush with the inside of the expansion roller 410, when the convex tooth rubber wheel sleeve 411 is in contact with the wall surface, the opposite pressure forces the material of the convex tooth rubber wheel sleeve 411 to deform, and the deformation amount is determined by the position of the face plate 502, and when a certain limit is reached, the outer sides of the two face plates 502 are also fully attached to the two sides of the wall, and the purpose of the above process test is to ensure that the face plate 502 does not jump when moving, and when the device is slow, the exciter 503 located at the front end of the face plate 502 is in an open state, and the energy generated is excited from the equidistantly arranged emission heads 504, and is emitted in a straight line along the wall surface, the laser emitted by the emission heads 504 is of a common 635-670nm red light or infrared laser, and the reflected light beam is captured by the reflective window 506 and then received by the receiver 505, and the round-trip time or phase difference of the laser is calculated to determine the distance between the measurement point and the receiver 505, the photodetector used by the receiver 505 is CMOS, which can stably convert the optical signal into an electrical signal and perform high-precision phase measurement, and the obtained data is fed back to the microprocessor 507 in real time, the received distance data and position data are integrated to generate a three-dimensional point cloud model, and the wall flatness parameter is calculated, the algorithm involved is mainly a filtering algorithm, a least squares method is used to fit a reference plane, and the deviation value of each point from the reference point light beam emission point is calculated, and finally the wall surface complete parameter in front of the path is presented by the visual screen 508 for subsequent personnel to check and record.

[0046] In a more optimized scheme, as shown in Figure 3 and Figure 8As shown, the end of each face support plate 502 is indirectly connected with a pointer 510, and the back of the collection long plate 1 is provided with two concave scales 511, which are respectively located at the upper and lower ends of the collection long plate 1. The pointer 510 is used to align the concave scale 511 to measure the width of the wall. The outer wall of each associated frame 501 is connected with an extension plate 509, and each concave scale 511 is fixed at the end of a corresponding extension plate 509.

[0047] In use, the two face support plates 502 can be closely attached to the two sides of the wall, and the extension plate 509 is flush with the outer side of the face support plate 502, so that the scale pointed by the pointer 510 fully represents the actual thickness of the wall. The adjacent scale of the concave scale 511 is 1mm. After the two pointers 510 are completely fixed, the relevant personnel can directly count the actual thickness of the wall, and the data is obtained the fastest.

[0048] In some embodiments, as Figures 6-7 As shown, the combined mechanical assembly 600 includes a square seat 601, the front of which is provided with a side support plate 602 for fitting the side of the wall. The upper part of the square seat 601 is provided with a roll 609, the inside of which is wound with a soft measuring tape 610. The front end of the soft measuring tape 610 is connected with a metal cone 611. After the expansion roller 410 drives the device to move to the highest part of the wall, the metal cone 611 is released, the soft measuring tape 610 is unwound, and the height of the wall is measured. The bottom of the square seat 601 is provided with a circular cover 603, the inside of which is connected with an electromagnetic ring 604. The inside of the square seat 601 is provided with a guide groove 605. The inner diameter of the circular cover 603 is matched with the metal cone 611. The bottom of the metal cone 611 is provided with a vibration sensor 613. The sensing end cover of the vibration sensor 613 is attached with a lower protective rubber base 614. The top of the square seat 601 is connected with two second external brackets 606. The top of each second external bracket 606 is provided with a connector 607. The opposite sides of the two connectors 607 are movably connected with a horizontal rod 608. The roll 609 is sleeved on the outer wall of the horizontal rod 608. The inner wall of each connector 607 is provided with a zooming spring 612. One end of each zooming spring 612 is fixedly connected with the two ends of the roll 609. The upper part of the square seat 601 is provided with a macro camera 615.

[0049] In use, the wall to be measured is mostly in an unfinished state, and the wall surface needs to be painted, but the side of the wall is still in the rough stage. Therefore, the upper and lower ends of the side support plate 602 connected with the square seat 601 are designed as arc surfaces to reduce the friction of the concrete structure layer and ensure that the device can move smoothly. When the device rises to the top end of the wall, as Figure 8As shown, the metal cone 611 loses magnetic force adsorption under the action of gravity and freely falls under the traction effect of the soft measuring tape 610. The coiling roller 609 can freely roll by the movable connection of the joint 607 and the crossbar 608. The metal cone 611 falls while the soft measuring tape 610 is always in the unwinding state. At the same time, the zooming springs 612 on both sides of the coiling roller 609 are continuously contracted. When the metal cone 611 is about to contact the ground, the lower protective rubber base 614 is contacted first, and the impact vibration is quickly captured by the vibration sensor 613. The signal exceeding the preset value is fed back to the relevant modules in the electric control box 9 in real time, and the micro distance camera 615 is timely controlled to be turned on. Because the micro distance camera 615 is located at the unwinding starting point of the soft measuring tape 610, the image shot can accurately reflect the actual height of the wall body. The data stored in the relevant modules in the electric control box 9 can be viewed from the embedded screen 10. Because the zooming spring 612 is retracted and twisted, a reverse rebound force is generated. When the metal cone 611 contacts the ground, the soft measuring tape 610 is in a straightened state under the rebound effect. When the device moves downward, the coiling roller 609 reversely rotates under the guidance of the rebound external force, assists the soft measuring tape 610 to be wound, and the metal cone 611 completely enters the round cover 603 and is adsorbed by the electromagnetic ring 604 which is powered again.

[0050] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
