Description

Therefore, during surveying and mapping work, the accurate measurement and evaluation of the wall verticality are crucial.

[0003] Patent CN202310692824.9 discloses a building wall verticality detection device. Although the detection device in this patent can measure the verticality of the wall, the measurement position is limited to the verticality at the measurement position of the measuring rod.

[0038] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0039] As Figure 1-8 shown, the present invention provides a wall verticality detection device for building construction, including a support mechanism. The support mechanism includes a base 101. A first moving wheel 103 is installed at the bottom of the base 101. The moving wheel is a universal wheel with a brake. On the one hand, it is convenient for the movement of the device. On the other hand, in the braked state, the device can be kept stable during the detection process. A connecting arm 102 is provided on one side of the base 101. The connecting arm 102 is perpendicular to the base 101. An adjusting mechanism is provided at the end of the connecting arm 102 away from the base 101. The adjusting mechanism is used to adjust the support mechanism. It should be noted that taking the extension direction of the base 101 as the front and back, and the extension direction of the connecting arm 102 as the left and right, the adjusting mechanism adjusts the levelness of the support mechanism in the left and right directions rather than the levelness in the front and back directions. It further includes:

[0040] Comparison mechanism. The comparison mechanism includes a comparison plate 301 and a drawing component. A standard comparison line 302 is provided on the comparison plate 301. The standard comparison line 302 is a straight line and is parallel to the movement path of the movable block 506, and is used to determine the reference line for detection. The drawing component is used to draw a curve fitting the wall on the comparison plate 301, so as to achieve the purpose of comparing with the standard comparison line 302 to judge the verticality and flatness of the wall. Preferably, between the two ends of the standard comparison line 302, a plurality of scale lines perpendicular to the standard comparison line 302 are also provided on the comparison plate 301. Through the scale lines, the distance by which the wall fitting curve deviates from the standard comparison line 302 can be observed, so as to judge the verticality of the wall;

[0041] Lifting mechanism. The lifting mechanism is arranged on the top of the base 101. The lifting mechanism is used to drive the drawing component to lift and draw a curve fitting the wall;

[0042] Drive mechanism. The drive mechanism is used to drive the lifting mechanism to operate;

[0043] Calibration mechanism. The calibration mechanism is used to measure the verticality of the lifting mechanism, so as to adjust the verticality of the lifting mechanism through the adjusting mechanism, so that the drawing component moves in the vertical direction. The calibration mechanism is used to provide a reference for adjusting the support mechanism through the adjusting mechanism.

[0044] Among them, a groove 303 is provided at each end of the comparison plate 301 on both sides of the standard comparison line 302, and inclined surfaces 304 are provided on one side of the inner walls of the two grooves 303 facing each other. Both ends of the inclined surface 304 are smoothly transitioned with the inner wall of the groove 303 and the surface of the comparison plate 301. The groove 303 is used to provide a reference for the drawing component at the start of measurement. By placing the writing end of the pen core 407 in the drawing component into the groove 303, the starting point of the wall-fitting curve drawn can coincide with the end point of the standard comparison line 302. During the process of drawing the wall-fitting curve, the distance between the wall-fitting curve and the standard comparison line 302 is the distance by which the wall deviates from the vertical plane.

[0045] Among them, the lifting mechanism includes two fixing frames one 501 symmetrically arranged on the top of the base 101. A lifting frame 502 is installed between the two fixing frames one 501. A rotating shaft 503 is installed at the top and bottom of the lifting frame 502 respectively. A pair of synchronous pulleys 504 are symmetrically installed on the surfaces of the two rotating shafts 503. The synchronous pulley 504 and the rotating shaft 503 can be rotatably connected or fixedly connected. In the case where the synchronous pulley 504 and the rotating shaft 503 are fixedly connected, the rotating shaft 503 and the lifting frame 502 need to be rotatably connected. Synchronous belts 505 are jointly sleeved on the surfaces of the two synchronous pulleys 504 corresponding to different positions on the surface of the rotating shaft 503. A movable block 506 is slidably installed on the side of the lifting frame 502 away from the connecting arm 102. A connecting frame 507 is provided at the top of the fixing frame one 501 close to the connecting arm 102, and both the connecting frame 507 and the movable block 506 are fixedly connected to the synchronous belt 505. The distance between the synchronous belts 505 on both sides between the two sides of the connecting frame 507 and the two sides of the movable block 506 is equal. During the rising process of the lifting frame 502, the connecting frame 507 moves downward relative to the lifting frame 502, thereby pulling the synchronous belt 505 and pulling the movable block 506 through the synchronous belt 505 to move upward relative to the lifting frame 502. That is, during the process of the movable block 506 moving from the bottom of the lifting frame 502 to the top, the lifting frame 502 simultaneously moves from the bottom of the fixing frame one 501 to the top. While enabling the movable block 506 to have a large moving stroke, the height of the telescopic device in the retracted state can be reduced, which is beneficial to the movement and transportation of the device and effectively improves the measurement range of the movable block 506.

[0046] Among them, the comparison board 301 is arranged on one side of the lifting frame 502 close to the connecting arm 102. The drawing assembly includes a drawing rod 401 penetratingly installed on the movable block 506. One end of the drawing rod 401 far from the comparison board 301 passes through one side of the lifting frame 502, and a mounting frame 402 is installed at the passed-through end. A roller 403 is installed on one side of the mounting frame 402 far from the drawing rod 401. The roller 403 can roll in the up-and-down direction of the wall surface. At the same time, the roller 403 can move according to the undulation of the wall surface, thereby driving the drawing rod 401 to draw a curve. The other end of the drawing rod 401 passes through the other side of the lifting frame 502, and a drawing pen 404 is installed at the passed-through end. The drawing pen 404 is used to draw a curve on the comparison board 301. A first spring 405 is installed on the surface of the drawing rod 401 between the mounting frame 402 and the movable block 506, and both ends of the first spring 405 are abutted against the mounting frame 402 and the movable block 506 respectively. The first spring 405 is used to realize the rebound of the mounting frame 402 and the roller 403, so as to achieve the effect that the roller 403 always fits on the wall surface.

[0047] Among them, the drawing pen 404 includes a hollow pen sleeve 406 fixedly connected to the drawing rod 401. A pen core 407 is installed inside the hollow pen sleeve 406. The pen core 407 is movably installed inside the hollow pen sleeve 406, and the writing end of the pen core 407 passes through one end of the hollow pen sleeve 406 close to the comparison board 301. The writing end of the pen core 407 is used to draw on the comparison board 301. A fixing cover 408 is installed at one end of the hollow pen sleeve 406 far from the comparison board 301. The fixing cover 408 is detachably installed. Specifically, the fixing cover 408 and the hollow pen sleeve 406 can be connected through a threaded structure, so that the fixing cover 408 can be opened, which is convenient for taking out the internal pen core 407 for replacement. A second spring 409 is installed inside the hollow pen sleeve 406 between the pen core 407 and the fixing cover 408, and both ends of the second spring 409 are abutted against the fixing cover 408 and the opposite side of the pen core 407 respectively. The pen core 407 is squeezed by the second spring 409, so that the writing end of the pen core 407 can abut against the surface of the comparison board 301, thereby improving the stability during the drawing of the wall-fitting curve.

[0048] Among them, the adjusting mechanism includes a through hole 201 arranged at the top of the connecting arm 102. An adjusting rod 202 is installed inside the through hole 201. A second moving wheel 204 is installed at the bottom end of the adjusting rod 202. The second moving wheel 204 can be a universal wheel without a braking function or a universal wheel with a braking function. The adjusting rod 202 is used to adjust the height of the second moving wheel 204, thereby realizing the horizontal adjustment of the supporting mechanism. An adjusting block 203 is arranged at the top end of the adjusting rod 202.

[0049] In one of the embodiments, internal threads are provided on the inner wall of the through hole 201, external threads engaging with the internal threads are provided on the outer side of the adjusting rod 202, and the adjusting rod 202 and the through hole 201 are threadedly connected through the internal and external threads. In this embodiment, by rotating the adjusting rod 202 threadedly connected to the through hole 201, the height of the moving wheel can be changed, thereby realizing the horizontal adjustment of the support mechanism.

[0050] In another embodiment, the adjusting rod 202 is slidably connected to the through hole 201. A screw rod 205 is threadedly installed on one side of the connecting arm 102, and one end of the screw rod 205 penetrates into the through hole 201. The other end of the screw rod 205 is connected with a knob 206. In this embodiment, after adjusting the connecting arm 102 to be horizontal by the adjusting rod 202, the knob 206 can be rotated to change the depth of the screw rod 205 penetrating into the through hole 201, thereby realizing the locking of the adjusting rod 202 to achieve the purpose of keeping the connecting arm 102 in a horizontal state.

[0051] Among them, the calibration mechanism includes a second fixing frame 601 fixedly arranged at the top of the connecting arm 102. A calibration plate 602 is arranged at the top of the second fixing frame 601. Calibration lines are arranged on the calibration plate 602, and the calibration lines are arranged parallel to the moving path of the movable block 506. A calibration pointer 603 is rotatably installed on one side of the calibration plate 602. A connecting rod 604 is arranged at the bottom of the calibration pointer 603. The bottom end of the connecting rod 604 is connected to an inverted U-shaped frame 605. A swing shaft 606 is further arranged inside the second fixing frame 601. A fixing block 607 is arranged in the middle of the swing shaft 606. A rotating frame 608 is rotatably installed on the outside of the fixing block 607. A suspension rod 609 is arranged at the bottom of the rotating frame 608. The bottom end of the suspension rod 609 is connected to a plumb bob 610. A connecting plate 611 is arranged at the top of the rotating frame 608. A strip-shaped groove 612 is formed in the connecting plate 611. A linkage rod 613 is arranged inside the inverted U-shaped frame 605. The linkage rod 613 is arranged in the front-back direction and passes through the inside of the strip-shaped groove 612. Under the action of gravity, the plumb bob 610 and the suspension rod 609 always maintain a vertically downward state. Therefore, according to the inclination state of the support mechanism, the plumb bob 610 will swing left or right, causing the connecting plate 611 to generate corresponding movements. Through the connecting plate 611, the linkage rod 613 rotates in the direction opposite to the moving direction of the plumb bob 610. During this process, the front-back swing of the plumb bob 610 is filtered through the rotation of the swing shaft 606 and the setting of the strip-shaped groove 612, so that the front-back swing of the plumb bob 610 will not cause the calibration pointer 603 to rotate. The left-right swing of the plumb bob 610 causes the calibration pointer 603 to deviate from the calibration line. At this time, the angle between the calibration pointer 603 and the calibration line is the inclination angle of the support mechanism. By adjusting the height of one end of the connecting arm 102 through the adjustment mechanism, the calibration line can be kept vertical in the left-right direction, so that the calibration pointer 603 coincides with the calibration line, and the moving path of the movable block 506 can be kept vertical in the left-right direction.

[0052] The driving mechanism includes a slide groove 701 provided on the fixed frame 501, and sliders 702 are provided at the bottom of both sides of the lifting frame 502. The two sliders 702 are respectively inserted into the two slide grooves 701, and the sliders 702 are slidably connected with the slide grooves 701. The arrangement of the sliders 702 and the slide grooves 701 can improve the stability of the lifting frame 502 during the rising and falling process. A lead screw 703 is installed inside the slide groove 701, and the lead screw 703 passes through the slider 702, and the slider 702 is connected with the lead screw 703. 03 are threadedly connected. When the lead screw 703 rotates, the lead screw 703 threadedly connected thereto will move upward or downward according to the direction of rotation of the lead screw 703. A mounting groove is provided inside the base 101. The bottom end of the lead screw 703 penetrates into the mounting groove, and one end penetrated therein is connected with a bevel gear 1 704. A transmission shaft 705 is also installed in the mounting groove. Two bevel gears 2 706 are provided on the surface of the transmission shaft 705, and the two bevel gears 2 706 are respectively meshed and connected with the two bevel gears 1 704.

[0053] At this time, the thread directions of the two lead screws 703 need to be set in opposite directions. When the two bevel gears 706 are both located on one side of the bevel gear 1 704, since the two lead screws 703 have the same rotation direction, the thread directions of the two lead screws 703 need to be set in the same direction. A motor 707 is also fixedly installed inside the mounting groove, and the output end of the motor 707 is connected to the transmission shaft 705 for transmission. The transmission shaft 705 is driven by the motor 707 to rotate, and the lead screw 703 is driven to rotate through the bevel gear 1 704 and the bevel gear 2 706.

[0054] Specific working principle:

[0055] Before using the detection device of the present invention, it is necessary to first connect the present invention to an external power source and a controller.

[0056] Step 1: When using the present invention, first move the device to the vicinity of the wall to be detected, and at the same time make the end of the drawing rod 401 provided with the roller 403 face the wall, and then start to calibrate the drawing starting point and verticality of the drawing pen of the device:

[0057] The calibration method of the drawing pen 404 is as follows: the device is pushed close to the wall, and is blocked by the wall. The drawing rod 401 remains stationary, and the comparison plate 301 continues to approach the wall. After the writing end of the pen core 407 coincides with the groove 303 at the bottom end of the standard comparison line 302, the writing end of the pen core 407 bounces into the groove 303 under the elastic force of the second spring 409, completing the initialization setting of the drawing origin, and then locking the brake on the moving wheel 103;

[0058] The verticality calibration method is as follows: While keeping the drawing pen 404 in the groove 303, by observing the pointing of the calibration pointer 603 on the calibration plate 602, if the calibration pointer 603 is on the left side of the calibration line, it means that the left side of the support mechanism is lower. At this time, by adjusting the mechanism to increase the height of the end of the connecting arm 102 away from the base 101, the calibration pointer 603 can be made to coincide with the calibration line. Similarly, if the calibration pointer 603 is on the right side of the calibration line, the height of the end of the connecting arm 102 away from the base 101 needs to be decreased to make the calibration pointer 603 coincide with the calibration line;

[0059] After the calibration is completed, the detection of the wall verticality begins.

[0060] Step 2: After starting the detection, start the motor 707 through an external controller. The motor 707 drives the transmission shaft 705 to rotate. The transmission shaft 705 drives the bevel gear two 706 on its surface to rotate. The bevel gear two 706 drives the bevel gear one 704 meshing with it to rotate. Finally, the two bevel gears one 704 drive the two lead screws 703 to rotate respectively. During the rotation of the lead screws 703, the slider 702 threadedly connected to them drives the lifting frame 502 to rise. Through the setting of the two lead screws 703, the two sides of the lifting frame 502 are balanced in force during the movement, which is conducive to improving the stability of the movement of the lifting frame 502 and the movable block 506 installed inside the lifting frame 502, so that the measured data is more accurate. During the rising of the lifting frame 502, the connecting frame 507 moves downward relative to the lifting frame 502 and pulls the synchronous belt 505 to rotate. During the rotation of the synchronous belt 505, the movable block 506 connected to the synchronous belt 505 moves upward inside the lifting frame 502 and drives the drawing assembly to move. At the same time, as the wall undulates, the drawing pen 404 in the drawing assembly will move synchronously to the left or right, and thus a curve fitting the undulating state of the wall is drawn on the comparison board 301. At the same time, since the starting point of this curve is the same as that of the standard comparison line 302, only by observing the distance between the curve and the standard comparison line 302 can the undulating situation of the wall and the verticality information of the wall be judged. It should be noted that the travel of the movable block 506 relative to the ground is twice its travel relative to the comparison board 301, that is, the length of the wall fitting curve drawn is half of the measurement height.

[0061] Step 3: After completing one measurement, only the drawn curve on the comparison board 301 needs to be erased, and the device is moved near the next wall to be measured. Then, repeat Steps 1 to 2. If the next wall to be measured is relatively close, during the process of performing Steps 1 to 2, it is not necessary to reset the lifting mechanism. Instead, make the writing end of the drawing pen 404 coincide with the groove 303 at the top of the standard comparison line 302, and detect the wall surface from top to bottom. When the next wall to be measured is far away, it is necessary to first reset the lifting mechanism to facilitate the movement of the device; after the ink in the refill 407 is used up, only need to open the fixing cover 408, remove the second spring 409 and the refill 407 in sequence, and after putting a new refill 407, install the second spring 409 and the fixing cover 408 in sequence.
