Description

Technical Field

[0001] This utility model relates to the field of building inspection technology, specifically to a multi-point detection device for the length and width of cracks in building walls. Background Technology

[0002] Building walls mainly consist of load-bearing walls and non-load-bearing walls, primarily serving to enclose and divide space. In load-bearing structures, the walls combine load-bearing and enclosure functions; in frame structures, the walls' role is both enclosure and space division. Walls must possess sufficient strength and stability, and have the capabilities of thermal insulation, sound insulation, fire resistance, and waterproofing. There are various types of building walls, including those made of single materials and composite materials. Designing a reasonable wall scheme by comprehensively considering factors such as enclosure, load-bearing capacity, energy efficiency, and aesthetics is a crucial task in building construction.

[0003] However, in the existing technology, when detecting cracks on building walls, the irregularity of the cracks results in different lengths and widths, as well as different locations. This makes it difficult to detect cracks at high locations from multiple points, and also limits the detection length. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-point detection device for the length and width of building wall cracks, which has the advantages of flipping and unfolding, adjusting the detection height, performing multi-point detection of the width of building wall cracks at high locations, and detecting the length of building wall cracks, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-point detection device for the length and width of cracks in building walls, comprising a terminal component, a width detection component, and a length detection component. The terminal component is used to record detection data. The width detection component is disposed on the terminal component for detecting the width of cracks in building walls. The length detection component is disposed on the terminal component for detecting the length of cracks in building walls. The width detection component includes a slide rail, a concave plate, a slider, a pull rod, and a spring. The slide rail is disposed on the terminal component. The concave plate is fixedly installed on one outer wall of the slide rail. The slider is slidably installed inside the slide rail. The pull rod is slidably installed inside the slide rail. One end of the pull rod is fixedly connected to one outer wall of the slider. The spring is fixedly installed on one outer wall of the slider. One end of the spring is fixedly connected to one inner wall of the slide rail.

[0006] Furthermore, a baffle is provided inside the concave plate, and two telescopic rods are fixedly installed on one inner wall of the concave plate, with the telescopic ends of the two telescopic rods being fixedly connected to the baffle.

[0007] Furthermore, a groove is provided on one side of the outer wall of the slide rail, a pointer is provided in the groove, the pointer is fixedly connected to the slider, and a scale is fixedly installed on one side of the outer wall of the slide rail.

[0008] Furthermore, the width detection assembly also includes two mounting plates, two connecting plates, two sleeves, two slide rods, two limiting plates, two damping plates, and two top plates. The two mounting plates are respectively fixedly installed on the top of the concave plate and the slider. The two connecting plates are respectively fixedly installed on the top of the two mounting plates. The two sleeves are respectively hinged to one side of the outer wall of the two connecting plates. The two slide rods are respectively slidably installed inside the two sleeves. The two limiting plates are respectively fixedly installed at the bottom end of the two slide rods. The two damping plates are respectively fixedly sleeved on the two limiting plates. The two top plates are respectively fixedly installed at the top end of the two slide rods.

[0009] Furthermore, the terminal assembly includes a recording terminal, a display screen, a side panel, and a rotating column. The display screen is fixedly installed on one outer wall of the recording terminal, the side panel is fixedly installed on one outer wall of the recording terminal, the rotating column is rotatably installed on the side panel, and the slide rail is fixedly installed on the top of the recording terminal.

[0010] Furthermore, the length detection component includes a laser rangefinder, a mounting ring, a connecting tube, a folded cylinder, a reflector, a mounting tube, and a soft rubber ring. The laser rangefinder is fixedly mounted on one end of the rotating column, the mounting ring is fixedly mounted on the bottom of the laser rangefinder, the connecting tube is rotatably mounted inside the mounting ring, the folded cylinder is fixedly mounted on the bottom end of the connecting tube, the reflector is fixedly mounted inside the folded cylinder, the mounting tube is fixedly mounted on one outer wall of the folded cylinder, and the soft rubber ring is fixedly mounted on the mounting tube.

[0011] Furthermore, the folded corner of the folded cylinder is set at a 45-degree angle, and the reflector is set inside the folded cylinder at a 45-degree angle.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are: This invention utilizes a width detection component. A rotating sleeve flips, causing a sliding rod and top plate to rotate. Pulling the sliding rod moves a limiting plate and a damping plate within the sleeve. Once the top plate is fully extended, pulling the sliding rod stops. The friction between the damping plate and the inner wall of the sleeve limits the position of the top plate, allowing it to extend into a crack in the building wall. As shown in the figure, the top plate on the left side contacts the inner wall of the crack. Pulling the pull rod causes it to slide within a slide rail, moving a slider within the rail. The slider compresses a spring, causing it to deform and accumulate elastic force. The slider then moves the sleeve and the right top plate, detecting the crack width. The crack width is displayed using a pointer and scale, and the data is recorded and displayed on a screen via buttons on a recording terminal. This invention offers advantages such as the ability to flip and unfold, adjust the detection height, and perform multi-point detection of crack widths in high-altitude building walls.

[0013] This invention utilizes a length detection component. A laser rangefinder is attached to a building wall, and rotating a folding cylinder causes a connecting tube to rotate within a mounting ring. This adjusts the observation point to suit the worker's viewing habits. The worker places their eye against the soft rubber ring, and the image from the laser rangefinder's lens is reflected by a reflector, allowing the worker to view and adjust the rangefinder. The rangefinder's position is then aligned with the crack. Flipping the recording terminal causes a side plate to rotate, adjusting its position on a rotating column. The laser rangefinder is then activated, detecting the crack in the building wall and recording the data via buttons on the recording terminal, which is then displayed on the screen. This invention offers the advantages of observing and adjusting crack patterns and detecting the length of cracks in building walls. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] This utility model provides, for example Figures 1-6As shown, a multi-point detection device for the length and width of cracks in building walls includes a terminal component 1, a width detection component 2, and a length detection component 3. The terminal component 1 is used to record detection data. The width detection component 2 is mounted on the terminal component 1 to detect the width of cracks in the building wall. The length detection component 3 is mounted on the terminal component 1 to detect the length of cracks in the building wall. The width detection component 2 includes a slide rail 201, a concave plate 202, a slider 203, a pull rod 204, and a spring 205. The slide rail 201 is mounted on the terminal component 1. The concave plate 202 is fixedly installed on one outer wall of the slide rail 201. The slider 203 is slidably installed inside the slide rail 201. The pull rod 204 is slidably installed inside the slide rail 201. The pull rod 204 is installed inside the slide rail 201. One end of the pull rod 204 is fixedly connected to the outer wall of one side of the slider 203. The spring 205 is fixedly installed on the outer wall of one side of the slider 203. One end of the spring 205 is fixedly connected to the inner wall of one side of the slide rail 201. More specifically, when the sleeve 208 is flipped, the sleeve 208 flips and drives the slide rod 209 and the top plate 212 to flip. When the slide rod 209 is pulled, the slide rod 209 drives the limiting plate 210 and the damping plate 211 to move inside the sleeve 208. After the slide rod 209 drives the top plate 212 to fully unfold, the sliding rod 209 is stopped. Through the friction between the damping plate 211 and the inner wall of the sleeve 208, the position of the top plate 212 is limited, allowing the top plate 212 to extend into the crack in the building wall. Figure 1 As shown, the top plate 212 on the left side contacts the inner wall of the crack. At this time, the pull rod 204 is pulled, and the pull rod 204 slides in the slide rail 201. When the pull rod 204 moves, it drives the slider 203 to move in the slide rail 201. When the slider 203 moves, it compresses the spring 205, causing the spring 205 to deform and accumulate elastic force. The slider 203 drives the sleeve 208 and the top plate 212 on the right side to move, thereby detecting the crack width. The crack width value is viewed through the pointer and scale. The data is recorded by the buttons on the recording terminal 101 and displayed on the display screen 102. It has the advantages of flipping and unfolding, adjusting the detection height, and performing multi-point detection of the crack width of building walls at high locations.

[0018] In addition, a baffle is provided inside the concave plate 202, and two telescopic rods are fixedly installed on one inner wall of the concave plate 202, with the telescopic ends of the two telescopic rods being fixedly connected to the baffle.

[0019] In addition, a groove is provided on one side of the outer wall of the slide rail 201, and a pointer is provided in the groove. The pointer is fixedly connected to the slider 203, and a scale is fixedly installed on one side of the outer wall of the slide rail 201.

[0020] In addition, the width detection component 2 also includes two mounting plates 206, two connecting plates 207, two sleeves 208, two slide rods 209, two limiting plates 210, two damping plates 211, and two top plates 212. The two mounting plates 206 are respectively fixedly installed on the top of the concave plate 202 and the slider 203. The two connecting plates 207 are respectively fixedly installed on the top of the two mounting plates 206. The two sleeves 208 are respectively hinged to one side of the outer wall of the two connecting plates 207. The two slide rods 209 are respectively slidably installed inside the two sleeves 208. The two limiting plates 210 are respectively fixedly installed at the bottom end of the two slide rods 209. The two damping plates 211 are respectively fixedly sleeved on the two limiting plates 210. The two top plates 212 are respectively fixedly installed at the top end of the two slide rods 209.

[0021] like Figure 1 As shown, the terminal assembly 1 includes a recording terminal 101, a display screen 102, a side panel 103, and a rotating column 104. The display screen 102 is fixedly installed on one outer wall of the recording terminal 101, the side panel 103 is fixedly installed on one outer wall of the recording terminal 101, the rotating column 104 is rotatably installed on the side panel 103, and the slide rail 201 is fixedly installed on the top of the recording terminal 101.

[0022] like Figure 1As shown, in some embodiments, the length detection component 3 includes a laser rangefinder 301, a mounting ring 302, a connecting tube 303, a folding cylinder 304, a reflector 305, a mounting tube 306, and a soft rubber ring 307. The laser rangefinder 301 is fixedly mounted on one end of the rotating column 104, the mounting ring 302 is fixedly mounted on the bottom of the laser rangefinder 301, the connecting tube 303 is rotatably mounted inside the mounting ring 302, the folding cylinder 304 is fixedly mounted on the bottom end of the connecting tube 303, the reflector 305 is fixedly mounted inside the folding cylinder 304, the mounting tube 306 is fixedly mounted on one outer wall of the folding cylinder 304, and the soft rubber ring 307 is fixedly mounted on the mounting tube 306. More specifically, when the laser rangefinder 301 is placed against a building wall and the folding cylinder 304 is rotated, the folding cylinder 304 causes the connecting tube 303 to rotate. The connecting pipe 303 rotates within the mounting ring 302 to adjust the observation point to suit the worker's observation habits. The worker places their eye against the soft rubber ring 307, and the image from the lens of the laser rangefinder 301 is reflected by the reflector 305, allowing the worker to view and adjust the laser rangefinder 301. The position of the laser rangefinder 301 is adjusted so that it is aligned with the crack. The recording terminal 101 is flipped, causing the side plate 103 to rotate. The side plate 103 rotates on the rotating column 104 to adjust its position. At this time, the laser rangefinder 301 is turned on, and it detects the cracks in the building wall. The detection data is recorded by the buttons on the recording terminal 101 and displayed on the display screen 102. It has the advantages of observing the crack line for adjustment and detecting the length of the cracks in the building wall.

[0023] In some embodiments, the folding angle of the folding cylinder 304 is set at 45 degrees, and the reflector 305 is set at a 45-degree angle inside the folding cylinder 304.

[0024] Working principle: Step 1: Width detection. Flip the sleeve 208. The sleeve 208 flips, causing the sliding rod 209 and top plate 212 to flip as well. Pull the sliding rod 209, which moves the limiting plate 210 and damping plate 211 within the sleeve 208. After the top plate 212 is fully extended, stop pulling the sliding rod 209. The friction between the damping plate 211 and the inner wall of the sleeve 208 limits the position of the top plate 212, allowing it to extend into the crack in the building wall. Figure 1As shown, the top plate 212 on the left side contacts the inner wall of the crack. At this time, the pull rod 204 is pulled, and the pull rod 204 slides in the slide rail 201. When the pull rod 204 moves, it drives the slider 203 to move in the slide rail 201. When the slider 203 moves, it compresses the spring 205, causing the spring 205 to deform and accumulate elastic force. The slider 203 drives the sleeve 208 and the top plate 212 on the right side to move, and the crack width is detected. The crack width value is viewed by the pointer and the scale. The data is recorded by the button on the recording terminal 101 and displayed on the display screen 102.

[0025] Step Two: Length Detection. Place the laser rangefinder 301 against the building wall. Rotate the folding cylinder 304, which in turn rotates the connecting tube 303 within the mounting ring 302. Adjust the observation point to suit the worker's observation habits. The worker places their eye against the soft rubber ring 307, reflecting the image from the laser rangefinder 301 through the reflector 305. This allows the worker to view and adjust the laser rangefinder 301, aligning it with the crack. Flip the recording terminal 101, which rotates the side plate 103, adjusting its position on the rotating column 104. The laser rangefinder 301 is then activated, detecting the crack in the building wall and recording the data via buttons on the recording terminal 101, which is then displayed on the screen 102.
