Description

Technical Field

[0001] The present invention relates to the technical field of flatness detection, and in particular to a flatness detection device for masonry wall construction. Background Art

[0002] A masonry wall refers to a wall built by using blocks and mortar through a certain masonry method.

[0003] The flatness detection of the wall surface is one of the items for house acceptance. The traditional wall surface flatness detection device is used by closely attaching it to the wall surface. It is easy to miss the detection of multiple positions on the wall surface. Later, in order to improve the detection accuracy, a wall surface flatness detection device using a writing pen for surveying and mapping has emerged in the prior art. This detection device realizes the flatness detection of the wall surface by elastically abutting the end of the writing pen against the wall surface and drawing different patterns on the paper based on the concave and convex state of the wall surface. Although this writing pen type of detection device is more detailed in detection than the traditional detection device, since the current such writing pen type of detection device can only move the writing pen in a single direction, therefore, it still has problems such as incomplete detection, poor detection effect, and low detection efficiency.

[0070] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0071] In the prior art, a writing pen-type detection device realizes the flatness detection of a wall surface by elastically abutting the end of the writing pen against the wall surface and drawing different patterns on the paper based on the concave and convex state of the wall surface. However, since it can only move the writing pen in a single direction, there are still technical problems such as incomplete detection, poor detection effect, and low detection efficiency.

[0072] In view of this, the present invention provides a flatness detection device for masonry wall construction, and the detection device includes:

[0073] A mounting frame 100 and a detection mechanism 200 arranged in the mounting frame 100;

[0074] One end of the detection mechanism 200 is a writing part 220;

[0075] The mounting frame 100 has a first state and a second state. After the mounting frame 100 is flipped in the vertical plane, it changes from the first state to the second state;

[0076] When the mounting frame 100 is in the first state, the writing part 220 of the detection mechanism 200 can move in the horizontal direction;

[0077] When the mounting frame 100 is in the second state, the writing part 220 of the detection mechanism 200 can move in the vertical direction.

[0078] Specifically, as Figure 1 、 Figure 2 shown, the axis direction of the detection mechanism 200 is the same as the opening direction of the mounting frame 100, and the detection mechanism 200 can move relative to the mounting frame 100. Among them, the writing part 220 is the end of the detection mechanism 200 far from the wall surface, and a surveying piece capable of clearly displaying the writing trace is arranged on the writing side of the writing part 220, such as a paper 1000, a surveying board, etc. In this embodiment, the surveying piece is the paper 1000. By rotating the mounting frame 100 in the direction parallel to the wall surface, the mounting frame 100 can be made to present the first state or the second state. Among them, the first state is the horizontal state, and the second state is the vertical state. It should be emphasized that during the rotation process, the opening direction of the mounting frame 100 always remains unchanged. When the mounting frame 100 is in the horizontal state, each detection mechanism 200 can leave a horizontal track corresponding to its own movement track on the paper 1000. When the mounting frame 100 is in the vertical state, each detection mechanism 200 can leave a vertical track corresponding to its own movement track on the paper 1000, so as to realize a comprehensive and detailed detection of the wall surface. At the same time, by leaving a track diagram with perpendicular lines crossed on the paper 1000, the staff can directly and quickly find the position of the problem wall surface, thus effectively improving the detection effect and detection efficiency.

[0079] In an optional solution of this embodiment, preferably, a plurality of detection mechanisms 200 are arranged in parallel in the mounting frame 100. When the mounting frame 100 is in the horizontal state, the connecting lines of the detection mechanisms 200 are vertical. When the mounting frame 100 is in the vertical state, the connecting lines of the detection mechanisms 200 are horizontal, so as to effectively improve the detection efficiency of the present invention.

[0080] The mounting frame 100 realizes the transformation between the first state and the second state through the flipping mechanism 300. The specific shape and structure of the flipping mechanism 300 are described in detail as follows:

[0081] The flipping mechanism 300 includes a first telescopic part 310 and a second telescopic part 320, as Figure 1As shown, the plane where the first telescopic part 310 and the second telescopic part 320 are located is a vertical plane, and the force application points of the first telescopic part 310 and the second telescopic part 320 are the diagonals of the mounting frame 100; the flipping mechanism 300 is configured to drive the mounting frame 100 to flip in the vertical plane by extending the first telescopic part 310 and contracting the second telescopic part 320, or by contracting the first telescopic part 310 and extending the second telescopic part 320.

[0082] Specifically, as Figure 2 shown, the mounting frame 100 is arranged on a bottom plate 400. Arc-shaped groove plates 500 are arranged at the diagonals of the mounting frame 100. The fixed ends of the first telescopic part 310 and the second telescopic part 320 are both connected to the bottom plate 400. Mounting grooves for the first telescopic part 310 and the second telescopic part 320 to rotate are provided on the bottom plate 400 to realize the hinge connection between the first telescopic part 310 and the second telescopic part 320 and the bottom plate 400. The movable ends of the first telescopic part 310 and the second telescopic part 320 are correspondingly connected to an arc-shaped groove plate 500. Specifically, two arc-shaped groove plates 500 are arranged in parallel on the two diagonals of the mounting frame 100. An arc-shaped groove 510 is provided on each arc-shaped groove plate 500. The movable ends of the first telescopic part 310 and the second telescopic part 320 are rotationally connected with a movable shaft 330 through a bushing. The movable shaft 330 is arranged between two adjacent arc-shaped groove plates 500, and the movable shaft 330 is slidably connected with the inner wall of the arc-shaped groove 510 to realize the movable connection between the first telescopic part 310 and the second telescopic part 320 and the mounting frame 100.

[0083] In this embodiment, by adjusting the lengths of the first telescopic part 310 and the second telescopic part 320, the distances between the two diagonals of the mounting frame 100 from the bottom plate 400 can be correspondingly changed, so as to achieve a rotation effect and realize the conversion between the horizontal state and the vertical state of the mounting frame 100.

[0084] Regarding the shape and structure of the detection mechanism 200, specifically:

[0085] The detection mechanism 200 further includes a detection rod 230 and a contact part 210. As Figure 3 shown, the contact part 210 and the writing part 220 are connected to both ends of the detection rod 230. The contact part 210 is a first roller and abuts against the wall surface.

[0086] The writing part 220 includes a first writing pen 221, a second writing pen 222 and a fixing block 223. As Figure 5As shown, the first writing pen 221 and the second writing pen 222 are connected to the fixed block 223. The second writing pen 222 is arranged parallel to the lower side of the first writing pen 221, and the tips of the first writing pen 221 and the second writing pen 222 are staggered front and back. One side of the fixed block 223 away from the first writing pen 221 and the second writing pen 222 is fixedly connected to the detection rod 230. A first fixing groove and a second fixing groove are arranged in the fixed block 223. A first elastic member connected to the first writing pen 221 is arranged in the first fixing groove, and a second elastic member connected to the second writing pen 222 is arranged in the second fixing groove. Specifically, the first elastic member and the second elastic member are set as the second spring in this embodiment.

[0087] In this embodiment, by arranging the tips of the first writing pen 221 and the second writing pen 222 front and back, and respectively arranging the first elastic member and the second elastic member at the ends of the first writing pen 221 and the second writing pen 222, when the contact part 210 touches walls with different flatness, the first writing pen 221 and the second writing pen 222 can cooperate with each other to draw different track lines, so that the staff can effectively identify whether the wall is flat and whether it is sunken or convex. Among them, the first elastic member and the second elastic member can also be used to buffer the first writing pen 221 and the second writing pen 222 to reduce the tip wear.

[0088] Furthermore, a connecting part 240 is also arranged on the detection rod 230, as Figure 3 、 Figure 4 shown. The upper end of the connecting part 240 is connected to the screw rod 600, and the lower end is sleeved on the detection rod 230. A threaded hole for connecting to the screw rod 600 is arranged at the upper end of the connecting part 240, and the opening direction of the threaded hole is perpendicular to the axis of the detection rod 230. The two ends of the screw rod 600 are respectively connected to the two frame sides of the mounting frame 100 in the horizontal direction. The screw rod 600 is used to rotate and drive the connecting part 240 to move along the axis direction of the screw rod 600. When the connecting part 240 moves, the contact part 210 and the writing part 220 realize synchronous movement through the detection rod 230.

[0089] In an alternative solution of this embodiment, preferably, as Figure 4 shown, a guide rod 1100 is also arranged parallel to one side of the screw rod 600 in the horizontal direction. The two ends of the guide rod 1100 are also respectively connected to the two frame sides of the mounting frame 100 in the horizontal direction. Correspondingly, a guide hole connected to the guide rod 1100 is also arranged on the connecting part 240, so that when the screw rod 600 rotates, the detection rod 230 can move along the axis direction of the screw rod 600 and keep its own axis direction unchanged.

[0090] Furthermore, the detection mechanism 200 further includes an elastic part 250, as Figure 3 、 Figure 4As shown, the elastic part 250 includes a first spring 251 and a limit ring 252; the limit ring 252 is fixed to one side of the connecting part 240, the first spring 251 is sleeved on the detection rod 230 and is located between the limit ring 252 and the connecting part 240, and the first spring 251 is configured to always have a tendency to drive the limit ring 252 to move towards the contact part 210. The elastic part 250 is used to ensure that the contact part 210 can always abut against the wall surface whether the wall surface is convex or concave.

[0091] Specifically, the specific setting position of the elastic part 250 can be set in various ways:

[0092] For example: the limit ring 252 is located on the side of the connecting part 240 close to the wall surface, and there may be no connection relationship or mutual fixed connection between the first spring 251 and the limit ring 252 and the connecting part 240. Preferably, the first spring 251 is fixedly connected to the limit ring 252 and the connecting part 240. During use, it is ensured that the first spring 251 is always in a compressed state to achieve the effect that the contact part 210 can always abut against the wall surface.

[0093] Also for example: the limit ring 252 is arranged on the side of the connecting part 240 away from the wall surface. At this time, the first spring 251 is fixedly connected to the limit ring 252 and the connecting part 240. During use, it is ensured that the first spring 251 is always in a stretched state to achieve the effect that the contact part 210 can always abut against the wall surface.

[0094] In an alternative solution of this embodiment, preferably, the detection device further includes a driving mechanism 900 for driving the screw 600 to rotate, such as Figure 1 、 Figure 2 As shown, the driving mechanism 900 includes a motor 910, a driving pulley group 920 and a driven pulley group 930. Among them, the driving pulley group 920 includes a driving wheel and a driving transmission belt for realizing the transmission connection between the driving pulley group 920 and the driven pulley group 930. The driven pulley group 930 includes a plurality of driven wheels and a driven transmission belt for realizing the transmission connection between the driven wheels. The number of driven wheels is correspondingly set with the number of screws 600. The motor 910 is fixedly connected to the mounting frame 100, and the output shaft of the motor 910 is fixedly connected to the axis of the driving pulley group 920; the driven pulley group 930 is in transmission connection with the driving pulley group 920, and the axis of the driven pulley group 930 is fixedly connected to the screw 600. When the driving motor 910 rotates, the driving pulley group 920 drives the driven pulley group 930 to rotate, so as to realize the rotation of the screw 600.

[0095] In an alternative embodiment of the present embodiment, preferably, the detection device further includes a drive box 1200 for protecting the driving pulley set 920 and the driven pulley set 930. The drive box 1200 is fixed to one side of the mounting frame 100. The driving pulley set 920 and the driven pulley set 930 are arranged inside the drive box 1200, and the motor 910 is fixed to one side of the drive box 1200.

[0096] The mounting frame 100 is placed on the placing mechanism 700. The specific shape and structure of the placing mechanism 700 are described in detail as follows:

[0097] As Figure 1 、 Figure 2 、 Figure 6 shown, a placing frame 710 is arranged between the bottom plate 400 and the mounting frame 100. The placing frame 710 is connected to the bottom plate 400 through a placing seat 1500. A placing groove for accommodating the mounting frame 100 is formed at the top of the placing frame 710. A buffer assembly 720 is connected to the bottom of the placing frame 710. A fixing cavity for accommodating the buffer assembly 720 is formed in the placing groove. The buffer assembly 720 includes a stretching rod 721 and a third spring 722. A retaining ring 723 is fixedly arranged on the peripheral side of the bottom of the stretching rod 721. One end of the third spring 722 is connected to the inner wall of the top of the fixing cavity, and the other end is connected to the retaining ring 723. Therefore, during the rotation of the mounting frame 100, the placing frame 710 can effectively buffer it to reduce the loss of the mounting frame 100.

[0098] Furthermore, as Figure 2 、 Figure 7 shown, guide pins 730 are fixedly connected to the groove walls on both sides of the placing groove. The placing frame 710 is provided with movable grooves that cooperate with the guide pins 730. The guide pins 730 are slidably connected to the movable grooves through bearings to ensure that when the mounting frame 100 rotates, it is always parallel to the wall surface itself, thereby effectively ensuring the accuracy of detection.

[0099] In an alternative embodiment of the present embodiment, preferably, as Figure 2 shown, a hydraulic cylinder 1300 and a base 1400 are further arranged below the bottom plate 400. The bottom of the hydraulic cylinder 1300 is connected to the base 1400, and the piston rod is connected to the bottom plate, so as to drive the bottom plate 400 to lift, making the detection range of the present invention wider and more convenient during use. At the same time, it should be added that second rollers 1410 are arranged at the four corners of the bottom of the base 1400 to facilitate the staff to move the detection device.

[0100] The paper 1000 is fixed through the paper fixing mechanism 800. The specific shape and structure of the paper fixing mechanism 800 are described in detail as follows:

[0101] The paper fixing mechanism 800 includes a fixing plate 810, asFigure 2 , Figure 8 As shown in Figure 8 , a paper clamping assembly 830 is provided on the fixing plate 810. The side of the fixing plate 810 adjacent to the mounting frame 100 is used to fix the paper 1000. The fixing plate 810 is arranged above the bottom plate 400. A transverse movement mechanism 840 for driving the fixing plate 810 to approach or move away from the mounting frame 100 is provided at the bottom of the fixing plate 810. The transverse movement mechanism 840 is arranged inside the bottom plate 400. The transverse movement mechanism 840 includes a transverse movement table and an adjusting rod rotatably connected to the transverse movement table. A cavity for the transverse movement table to move is formed inside the bottom plate 400. One end of the adjusting rod extends into the bottom plate 400 and is rotatably connected to the transverse movement table, and the other end extends out of the bottom plate 400 for the staff to rotate.

[0102] Furthermore, the paper clamping assembly 830 includes a clamping plate 831, a first magnet 832, and a second magnet 833. As Figure 9 shown in Figure 9 , the clamping plate 831 is movably connected to the fixing plate 810 through a connecting rod and can approach or move away from the fixing plate 810. A paper clamping space is formed between the clamping plate 831 and the fixing plate 810. Wherein, both ends of the connecting rod are hinged to the clamping plate 831 and the fixing plate 810 respectively. A first magnet 832 is embedded at the bottom of the clamping plate 831, and a second magnet 833 matched with the first magnet 832 is embedded on the fixing plate 810.

[0103] In this embodiment, when it is necessary to clamp the paper 1000, the clamping plate 831 is operated to separate it from the fixing plate 810, and then the edge of the paper 1000 is placed between the clamping plate 831 and the fixing plate 810. After that, the clamping plate 831 is released, so that the first magnet 832 and the second magnet 833 are attracted to each other again, and the clamping of the paper can be realized.

[0104] In an alternative embodiment of the present invention, preferably, as Figure 9 shown in Figure 9 , a handle 834 is also fixedly connected to the clamping plate 831 to facilitate the staff to clamp the paper 1000.

[0105] In an alternative embodiment of the present invention, preferably, as Figure 8 shown in Figure 8 , the paper fixing mechanism 800 further includes a scale 820. The scale 820 is fixed below the paper and is used to measure the trajectory diagram on the paper 1000 to improve the detection accuracy of the present invention.

[0106] The working process of the present invention is as follows:

[0107] During use, move this detection device to the side of the wall to be detected through the second roller 1410, adjust the installation frame 100 to a horizontal state, and make the contact part 210 on the detection rod 230 abut against the wall; at this time, it should be ensured that the first spring 251 is in a partially compressed state, and the first writing pen 221 abuts against the paper 1000, and the second writing pen 222 is separated from the paper 1000. Start the driving mechanism 900 to make the screw rod 600 drive the detection rod 230 to move cyclically along the axis direction of the screw rod 600, and the detection of the flatness of the wall in the horizontal direction can be realized.

[0108] After that, operate the transverse movement mechanism 840 to separate the paper 1000 from the first writing pen 221 and the second writing pen 222, and then start the flipping mechanism 300 to adjust the installation frame 100 to a vertical state. Adjust the transverse movement mechanism 840 again to restore the state between the paper 1000 and the first writing pen 221 and the second writing pen 222 to the original state. At this time, drive the screw rod 600 to drive the detection rod 230 to move, and the detection of the flatness of the wall in the vertical direction can be realized. Thus, a comprehensive and detailed detection of the wall can be achieved. At the same time, by leaving a trajectory map with perpendicular and intersecting lines on the paper 1000, the staff can directly and quickly find the problematic wall, thereby effectively improving the detection effect and detection efficiency. It should be noted that the initial state of the installation frame 100 can be a horizontal state or a vertical state.

[0109] Among them, the corresponding relationship between the trajectory maps drawn by the first writing pen 221 and the second writing pen 222 and the flatness of the wall is as follows:

[0110] When the wall is relatively flat, the first writing pen 221 abuts against the paper 1000, and the second writing pen 222 is separated from the paper 1000. At this time, a single straight line trajectory map is left on the paper 1000;

[0111] When there is a depression on the wall, the contact part 210 displaces towards the wall under the action of the first spring 251, thereby driving the first writing pen 221 away from the paper. At this time, there is no scratch on the paper;

[0112] When the wall bulges, the contact part 210 displaces in a direction away from the wall, thereby driving the second writing pen 222 to abut against the paper. At this time, a trajectory map with two parallel and adjacent straight lines is left on the paper.

[0113] 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 them; 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 described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
