Abstract
Description
Technical Field
[0001] This application belongs to the field of ground defect detection technology, specifically relating to a surface defect marking device for concrete floors. Background Technology
[0002] Concrete floors are durable surfaces formed by pouring a mixture of cement, sand, aggregate, and water, which then hardens. Over time, concrete floors are prone to surface defects such as cracks, hollow areas, and settlement. These defects not only affect the aesthetics but also the performance, safety, and lifespan of the concrete floor, necessitating timely repair and maintenance.
[0003] In existing technologies, it is necessary to first mark the location of appearance defects on the concrete floor, and then repair the appearance defects in different locations in sequence. The marking of appearance defects is usually done manually, which means that workers bring markers to the site, bend down to observe the appearance defects on the ground at close range, and mark them.
[0004] The inventors discovered that existing methods for marking appearance defects, when applied to long-distance roads, not only consume a lot of manpower and cause worker fatigue, but also have low marking efficiency. There are cases where workers miss some appearance defects due to lack of concentration or visual errors, affecting the efficiency and stability of appearance defect marking. Utility Model Content

Therefore, they should not be construed as limitations on this application.
[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0059] Please refer to the following: Figures 1 to 11 The present application provides a description of the appearance defect marking device for concrete floors. The appearance defect marking device for concrete floors proposed in this application includes two sets of guide rods 1, a positioning plate 2, an alignment seat 3, an image acquisition component 4, and a marking component 5.
[0060] Two sets of guide rods 1 are arranged side by side above the ground along the width direction of the ground. In this embodiment, for ease of description, the width direction of the ground is defined as the left-right direction. Correspondingly, the length direction of the ground is the front-back direction, and the direction perpendicular to the ground is the up-down direction.
[0061] Each set of guide rods 1 includes multiple guide rods 1 arranged along the length direction of the ground (i.e., the front-to-back direction). The multiple guide rods 1 are coaxially arranged, and two adjacent guide rods 1 are detachably connected. The two guide rods 1 at the ends have bases 6 for fixing to the ground, so as to achieve a fixed setting of the guide rods 1 above the ground.
[0062] The positioning plate 2 is slidably disposed between two sets of guide rods 1 along the length of the ground, and its two ends are slidably connected to the two sets of guide rods 1 in the front-back direction respectively; based on this, the positioning plate 2 is connected to a first linear drive mechanism 7, which can drive the positioning plate 2 to move relative to the guide rods 1 in the front-back direction.
[0063] The positioning seat 3 is slidably mounted on the positioning plate 2 along the arrangement direction (i.e., the left and right direction) of the two sets of guide rods 1; based on this, the positioning seat 3 is connected to a second linear drive mechanism 8, which can drive the positioning seat 3 to move relative to the positioning plate 2 in the left and right direction.
[0064] Image acquisition component 4 is mounted on positioning base 3 and is used to acquire image information from the ground; specifically, it can be divided into two cases:
[0065] (a) The image acquisition component 4 has a display screen that is electrically connected to it. The operator observes the display screen to determine whether there are any appearance defects in the image and manually controls the start of the marking component 5.
[0066] (ii) The image acquisition component 4 is equipped with a software module that can process images to achieve efficient data processing and convert the processing signal into a control signal for whether to start the marker component 5.
[0067] The marking component 5 is mounted on the alignment seat 3 to apply ground markings, and its marking position is close to or coincides with the acquisition area of the image acquisition component 4. In practice, these ground markings are usually short-term markings to facilitate later cleanup.
[0068] In this embodiment, the image acquisition component 4 can acquire ground image information of the location of the positioning seat 3, allowing the operator to determine whether there are any surface defects. If so, ground markings can be applied to the ground using the marking component 5. Furthermore, by using the first linear drive mechanism 7 to move the positioning plate 2 and the second linear drive mechanism 8 to move the positioning seat 3, the acquisition range of the image acquisition component 4 can be increased to cover the entire concrete surface to be inspected.
[0069] By selecting guide rods 1 of different lengths or numbers, the movement distance of the positioning plate 2 along the length of the ground can be extended, thereby improving the adaptability of this device to ground of different lengths.
[0070] The concrete surface defect marking device provided in this embodiment, compared with the prior art, can apply surface markings to the surface defects of concrete surfaces and improve the automation of the operation process, thereby reducing manpower consumption, avoiding errors, and improving the efficiency and stability of surface defect marking.
[0071] In some embodiments, such as Figures 5 to 7 As shown, the first linear drive mechanism 7 includes two roller seats 71 and two roller bodies 72.
[0072] Two roller seats 71 are respectively set at both ends of the positioning plate 2 and are detachably connected to the positioning plate 2. Specifically, the end of the positioning plate 2 has an outwardly extending side plate, and the roller seat 71 has a screw that passes through the side plate and extends outward. The extended part of the screw is threadedly connected to a nut that abuts against the inner side of the side plate, so as to realize the connection relationship between the roller seat 71 and the positioning plate 2.
[0073] Each roller seat 71 is provided with a connecting arm 9 on the side facing away from the positioning plate 2. In the direction of the roller seat 71 facing away from the positioning plate 2, the connecting arm 9 is inclined upward to adapt to the height of the guide rod 1. Each connecting arm 9 has a guide hole 91 suitable for the corresponding guide rod 1 to pass through, so as to realize its sliding connection with the guide rod 1.
[0074] The two roller bodies 72 are respectively rotatably mounted on the two roller seats 71, and the rotation axis is parallel to the arrangement direction (i.e., the left and right direction) of the two roller seats 71.
[0075] In actual use, the roller body 72 is used to contact the ground so that when it rotates, it drives the roller seat 71 to move in the front-back direction. Each roller seat 71 also has a rotation drive member 711 that is connected to the corresponding roller body 72 to drive the roller body 72.
[0076] In some embodiments, such as Figures 5 to 7 As shown, the rotation drive component 711 is a rotation motor; the rotation motor is fixedly installed on the side of the roller seat 71 facing the positioning plate 2, and its power output axis is parallel to the axis of the roller body 72.
[0077] Based on this, the rotating shaft of the roller body 72 passes through the roller seat 71 and extends out, and the extended end of the rotating shaft of the roller body 72 is coaxially connected to the power output end of the rotating motor to achieve the aforementioned transmission connection relationship.
[0078] A receiving groove 21 is provided on the end face of the positioning plate 2; when the positioning plate 2 and the roller seat 71 are connected by a combination structure of side plate, screw and nut, the end face of the positioning plate 2 is in contact with the outer side of the roller seat 71, and the rotating motor is embedded in the receiving groove 21 to achieve structural protection of the rotating motor.
[0079] In some embodiments, such as Figure 1 and Figure 7 As shown, the second linear drive mechanism 8 includes a transmission nut 81 and a transmission screw 82.
[0080] The transmission nut 81 is mounted on the positioning seat 3, and its axial direction is parallel to the sliding direction of the positioning seat 3.
[0081] The transmission screw 82 is rotatably mounted on the upper side of the positioning plate 2 and is threadedly connected to the transmission nut 81.
[0082] The upper side of the positioning plate 2 is provided with a rotary motor 821. The power output end of the rotary motor 821 is coaxially connected to the transmission screw 82 to drive the transmission screw 82 to rotate, thereby driving the combination structure of the transmission nut 81 and the positioning seat 3 to move along the axial direction of the transmission screw 82, that is, to move left and right.
[0083] In some embodiments, such as Figure 4 and Figure 7 As shown, the mounting base 3 includes two splicing shells 31 and a mounting platform 32.
[0084] Two splicing shells 31 are arranged on the upper side of the positioning plate 2 along the axial direction of the transmission screw 82; a recessed groove 311 is provided on the adjacent side of the two splicing shells 31, and a through hole 312 suitable for the transmission screw 82 to pass through is provided at the bottom of each recessed groove 311; in use, the two splicing shells 31 are joined together so that the two recessed grooves 311 can be combined to form a cavity that is compatible with the transmission nut 81, and the cavity has through holes 312 at both ends so that the transmission screw 82, which is threadedly connected to the transmission nut 81, can extend out.
[0085] The mounting platform 32 is slidably disposed on the lower side of the positioning plate 2 along the axial direction of the transmission screw 82; and the front and rear sides of the mounting platform 32 extend to the outside of the positioning plate 2, and the extended part has an upwardly extending clamping plate 321; correspondingly, the two clamping plates 321 are arranged side by side on the front and rear sides of the positioning plate 2 in the front-rear direction, and the upper end of the clamping plate 321 is on the upper side of the positioning plate 2, and is in contact with the outer side of the two splicing shells 31.
[0086] Each clamping plate 321 is detachably connected to two splicing shells 31 to restrict the relative movement of the two splicing shells 31; such as Figure 4 As shown, the clamping plate 321 is provided with two through holes arranged side by side in the left and right direction, and each splicing shell 31 is provided with a groove that communicates with the through holes; the inner wall of the groove has an internal thread structure, and each through hole is inserted with a connecting bolt that can be threadedly connected to the groove.
[0087] Both the image acquisition component 4 and the marking component 5 are located on the lower side of the mounting platform 32 to avoid interference from the related structures with the image acquisition and ground marking.
[0088] In some embodiments, such as Figure 3 and Figure 4 As shown, the image acquisition component 4 is a camera mounted on the mounting base 3. The camera is set facing the ground to capture ground images and transmit these ground images to a display screen that can receive the information transmitted from the camera.
[0089] In other words, the image acquisition component 4 includes a camera and a display screen. The camera is fixed on the alignment base 3, and the display screen is used for handheld observation by the operator.
[0090] In some embodiments, such as Figure 2 and Figure 3 As shown, the marking component 5 includes a storage tank 51 and a spray gun 52.
[0091] The storage tank 51 is mounted on the positioning plate 2 and is used to hold paint that can be applied to the ground and is easy to clean.
[0092] The spray gun 52 is mounted on the positioning seat 3 and is connected to the storage tank 51 via a hose 521.
[0093] In actual use, the output end of the spray gun 52 is set towards the ground, and it can extract the paint in the storage tank 51 and spray it onto the ground to form the aforementioned ground markings.
[0094] In some embodiments, such as Figure 1 and Figure 10 As shown, each guide rod 1 has a mounting screw 11 coaxially connected to its front and rear ends, and a threaded groove 12 coaxially arranged with it.
[0095] The mounting screw 11 is adapted to the threaded groove 12. The two adjacent guide rods 1 are connected by the threaded connection between the mounting screw 11 and the threaded groove 12. Specifically, by fixing one guide rod 1 and aligning the mounting screw 11 of the other guide rod 1 with the threaded groove 12, and then rotating one of the guide rods 1, the two guide rods 1 can be combined.
[0096] In some embodiments, such as Figures 8 to 11 As shown, each base 6 has a groove 61 suitable for the end of the guide rod 1 to be inserted. The bottom of each groove 61 is provided with a reserved hole 62 suitable for the installation screw 11 to pass through, and the reserved hole 62 is coaxially connected with the groove 61.
[0097] For the two bases 6 located at the ends, one base 6 has a locking nut 63 adapted to be threaded to the protruding end of the mounting screw 11 and abutting against the outer side of the base 6, and the other base 6 has a locking bolt 64 adapted to be inserted into the reserved hole 62 and threaded to the threaded groove 12, so as to realize the detachable connection between the base 6 and the mounting screw 11 located at the ends.
[0098] In some embodiments, such as Figure 9As shown, the locking nut 63 also includes a locking sleeve 65, which can be fitted onto the outer periphery of the corresponding mounting screw 11, and its two ends are respectively connected to the outer side of the locking nut 63 and the base 6, thereby filling the space between the locking nut 63 and the outer side of the base 6 and protecting the protruding mounting screw 11.
