Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a flatness detection device for construction engineering. Background Art

[0002] Construction engineering is a part of the construction project, referring to the engineering entity formed by the construction of various building structures and their ancillary facilities and the installation of pipelines, equipment, etc. matching with them. It includes factories, theaters, hotels, stores, schools, hospitals, and residences, etc., to meet the needs of people's production, living, learning, public activities, etc.

[0003] In a Chinese patent with the publication number CN114562932B, a flatness detection device for construction engineering quality is disclosed, belonging to the technical field of construction engineering. It includes a base, and a first support rod and a second support rod are arranged on the surface of the base facing away from the ground; a pointer is rotatably arranged on the first support rod, the rotation axis of the pointer is perpendicular to the length direction of the first support rod, and the rotation axis of the pointer is located at the center of gravity of the pointer; a drawing board is arranged on the second support rod, the plane where the pointer is located is parallel to the plane where the drawing board is located, multiple drawing papers are arranged on the drawing board, and a scale is drawn on the drawing paper; a first fixing member is arranged on the first support rod, and the first fixing member is used to fix the pointer to the static position after the pointer stops; an identification member is arranged on the pointer, and the identification member is used to draw the orthographic projection of the pointer on the scale on the drawing paper after the pointer stops and is fixed. This application has the effect of reducing the labor intensity of workers.

[0004] However, when the aforementioned device is applied to the flatness detection operation of construction engineering, it is necessary to first draw the orthographic projection position of the pointer on the scale on the drawing paper, and then complete the quality assessment of a specific engineering plane through multiple steps of complex calculations. This operation method not only lacks intuitiveness and is difficult to quickly obtain the flatness information of the engineering plane, but also the overall detection process is cumbersome, resulting in a significant restriction on the detection efficiency.

[0005] A flatness detection device for building engineering quality is disclosed in a Chinese patent with the publication number CN109764834B, which includes a crossbeam support and a connection mechanism. A first screw rod is further arranged below the crossbeam support. A first nut sleeve is threadedly connected to the first screw rod. An electric push rod is fixedly installed at the bottom of the first nut sleeve. The telescopic end of the electric push rod is fixedly installed with the connection mechanism. When performing flatness detection in the present invention, the position where the right side plate is located is selected as the reference position for detecting the flatness of the detection surface. The infrared capturing mechanism captures the infrared rays emitted by the infrared emitting mechanism and records in real time the distance between the infrared receiving point and the detection surface. Since the infrared rays are emitted horizontally, the distance between the receiving point and the detection surface is the distance between the emitting point and the detection surface, thereby realizing the detection of the flatness of the detection surface, without manual measurement, recording and calculation by workers, not only reducing the labor intensity of workers, but also improving the accuracy of flatness detection.

[0006] However, when using the above device to carry out the flatness detection operation of building engineering, the operator needs to first accurately move the device to the area to be detected and make it stop stably. Subsequently, the infrared detection module is driven to perform flatness detection on this area by rotating the first screw rod. When the detection range is large, this process requires repeated intermittent movement and positioning of the device, resulting in a long overall detection process. More critically, if there is an overall inclination in the area to be detected, the detection mechanism of this device will be difficult to accurately identify local flatness differences, easily leading to distorted detection results.

[0040] The embodiments of the present invention will be further described in detail below 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.

[0041] Embodiment 1:

[0042] As shown in the Figure 1 to Figure 7 drawings, the present invention provides a flatness detection device for construction projects, including a bottom plate 1, two sets of wing plates 2 welded to opposite sides of the bottom of the bottom plate 1. Dovetail grooves 201 are provided on the outer sides of the two sets of wing plates 2. An adjustment mechanism 3 is arranged inside the dovetail grooves 201. The auxiliary device is parallel to different inclined planes. A cavity box 4 is welded to the middle of the upper side of the bottom plate 1. An inclination detection mechanism 5 is arranged inside the cavity box 4 and extends to the outside of the cavity box 4 at one end and is welded to a frame 6. A Y-shaped bracket 8 is welded to the bottom of the frame 6, and push wheels 9 are rotatably connected to opposite sides of the end far from the frame 6. A vibration mechanism 13 is arranged outside the frame 6 and is used to remind the user of the inclined state of the building plane in cooperation with the inclination detection mechanism 5. A flatness detection mechanism 14 is arranged between the two sets of wing plates 2 for visually detecting the flatness of the project. One end of the frame 6 far from the cavity box 4 is welded with a push handle 7. A switch 12 is arranged on the top of the push handle 7. A baffle 10 is welded to the side of the frame 6 close to the Y-shaped bracket 8.

[0043] As can be seen from the above, when the device is used, first, the user pushes the device to the detection area through the push handle 7, and limits the rotation direction of the Y-shaped bracket 8 through cooperation with the baffle 10, and the device is assisted to move through the Y-shaped bracket 8 and the push wheels 9. Then, the bottom plate 1 is made parallel to the detection plane through the adjustment mechanism 3, so that the device can adapt to various inclined planes. Then, the switch 12 is turned on, and the device is pushed to move on the plane to be detected through the push handle 7. The inclination detection mechanism 5 is used to detect in real time whether there is local abnormal inclination on the plane. After this situation occurs, the vibration mechanism 13 knocks on the frame 6 at a high frequency to effectively remind the user. And through the flatness detection mechanism 14, it can be directly seen whether there are potholes on the project plane and a general judgment can be made on the potholed ground.

[0044] Embodiment 2:

[0045] As shown in the Figure 2As shown in the figure, this embodiment is basically the same as the previous one, except that the adjusting mechanism 3 includes a threaded rod 301 rotatably connected inside the dovetail groove 201. The top end of the threaded rod 301 extends to the upper side of the bottom plate 1 and is fixedly connected with a turning knob 302. A slider 303 is threadedly connected to the outer surface of the threaded rod 301. The slider 303 slides in the dovetail groove 201. Legs 304 are hinged to opposite sides of the bottom plate 1. A connecting rod 305 is hinged between the leg 304 and the slider 303. A traveling wheel 306 is provided at one end of the leg 304 away from the bottom plate 1.

[0046] As can be seen from the above, when the bottom plate 1 is not parallel to the plane to be detected, turn the turning knobs 302 on both sides of the device in sequence. When the turning knobs 302 rotate, they will drive the connected threaded rods 301 to rotate synchronously. During the rotation of the threaded rods 301, the sliders 303 will slide along the dovetail grooves 201. When the sliders 303 slide upward, the connecting rods 305 will tend to open. At this time, under the action of the traveling wheels 306, one side of the device will be correspondingly lowered. On the contrary, when the sliders 303 slide downward, the connecting rods 305 will gradually close, thereby raising one side of the device. During the entire adjustment process, the working state of the infrared detection module 505 needs to be closely monitored. When the specific wave emitted by the infrared emitter in the infrared detection module 505 can be successfully received by the infrared receiver, it indicates that the bottom plate 1 is precisely parallel to the plane to be detected. At this time, the adjustment operation can be stopped.

[0047] Embodiment Three:

[0048] As shown in the attached Figure 4 figure, this embodiment is basically the same as the previous one, except that the inclination detection mechanism 5 includes a support frame 501 fixedly connected inside the cavity box 4. A connecting rod 502 is rotatably connected inside the support frame 501 through a bearing. A fixed cylinder 503 is welded to the outer surface of the connecting rod 502. Notches 401 are opened on opposite sides of the top of the cavity box 4. L-shaped extension plates 504 are welded to opposite sides of the fixed cylinder 503. The L-shaped extension plates 504 extend to the top of the cavity box 4 through the notches 401 and are provided with an infrared detection module 505. One end of the connecting rod 502 away from the support frame 501 extends to the outside of the cavity box 4 and is welded with a connection block 506. The connection block 506 is fixedly connected to the frame 6. The infrared detection module 505 includes an infrared emitter and an infrared receiver. The infrared emitter and the infrared receiver are respectively arranged on one side of the two L-shaped extension plates 504 close to each other.

[0049] As described above, during the process of moving the device by pushing the push handle 7, if an abnormal inclination occurs in a certain area, the part at the front end of the device and below the bottom plate 1 will come into contact with the abnormal area first. Since the support frame 501 is fixedly connected to the inner wall of the cavity box 4 and is also connected to the connecting rod 502 in a rotatable manner, the entire front end of the device will tilt to one side, driving the cavity box 4 to tilt accordingly. The push handle 7 and the connecting rod 502 fixedly connected thereto will not tilt. In this way, the tilted side of the cavity box 4 will cause the infrared emitter or infrared receiver on the L-shaped extension plate 504 originally located on that side to gradually retract into the cavity box 4 through the notch 401, and the infrared receiver will no longer be able to receive the signal emitted by the infrared emitter. Therefore, it can be judged whether there is an abnormal inclination in the area to be detected based on this.

[0050] Embodiment 4:

[0051] As shown in the Figure 6 accompanying drawings, this embodiment is basically the same as the previous embodiment, except that the vibration mechanism 13 includes a connecting plate 1301 welded to the outside of the frame 6. One end of the connecting plate 1301 away from the frame 6 is fixedly connected with an L-shaped mounting plate 1302. A driving motor 1303 is fixedly installed on the rear side of the L-shaped mounting plate 1302. The output end of the driving motor 1303 extends to the front side of the L-shaped mounting plate 1302 and is fixedly connected with a turntable 1304. A rotating rod 1305 is rotatably connected to the front side of the L-shaped mounting plate 1302. A rectangular strip 1306 is fixedly connected to the outside of the rotating rod 1305. A through groove 1307 is opened on the outside of the rotating rod 1305. A cylinder 1308 is eccentrically arranged on the front side of the turntable 1304. The cylinder 1308 slides in the through groove 1307. A sector-shaped toothed plate 1309 is fixedly connected to the bottom of the rectangular strip 1306. The outer surface of the sector-shaped toothed plate 1309 is meshed with a rectangular toothed plate 1310. The rectangular toothed plate 1310 is slidably connected to the L-shaped mounting plate 1302. One end of the rectangular toothed plate 1310 close to the frame 6 is fixedly connected with an impact block 1311. A control module 11 is arranged on one side of the frame 6 close to the cavity box 4. The control module 11 is electrically connected to both the driving motor 1303 and the infrared detection module 505.

[0052] As described above, when the control module 11 detects an abnormality in the infrared detection module 505, it turns on the driving motor 1303. The driving motor 1303 drives the turntable 1304 to rotate, driving the cylinder 1308 to slide in the through groove 1307. The rectangular strip 1306 is driven to swing back and forth through the cooperation of the rotating rod 1305. The rectangular toothed plate 1310 is driven to slide linearly and reciprocally on the outside of the L-shaped mounting plate 1302 through the sector-shaped toothed plate 1309, thereby driving the impact block 1311 to collide with the frame 6 at a high frequency, and effectively reminding the user that there is an abnormal inclination in this area through the transmission of the push handle 7.

[0053] Embodiment 5:

[0054] As shown in the attached Figure 7 figure, this embodiment is basically the same as the previous one. The difference is that the flatness detection mechanism 14 includes a plurality of sliding rods 1401 linearly and equidistantly distributed on the outside of the bottom plate 1. A chute adapted to the sliding rods 1401 is provided on the outside of the bottom plate 1. Thrust springs 1402 are sleeved on the outside of the sliding rods 1401. One end of the thrust spring 1402 is fixedly connected to the bottom plate 1, and a detection wheel 1403 is provided at the other end of the thrust spring 1402. The middle of the detection wheel 1403 is fixedly connected to the sliding rod 1401, and a limiting plate 1404 is welded to the top of the sliding rod 1401.

[0055] As can be seen from the above, since the bottom plate 1 is already parallel to the detection plane through the adjustment mechanism 3, the plurality of detection wheels 1403 are always in contact with the detection plane under the thrust of the thrust springs 1402. When the push handle 7 pushes the device to move into a pitted area, the plurality of sliding rods 1401 will slide in the chutes on the outside of the bottom plate 1. When the corresponding detection wheel 1403 touches a ground protrusion in a certain area, the sliding rod 1401 drives the limiting plate 1404 to slide upward. When the corresponding detection wheel 1403 touches a ground depression in the area, the sliding rod 1401 drives the limiting plate 1404 to slide downward. During the movement of the device, it is only necessary to check in real time whether the heights of the plurality of sliding rods 1401 are consistent, so as to visually check the flatness of the area to be detected. And when the heights of the plurality of sliding rods 1401 show a tilt to one side, it can also be judged that an abnormal tilt situation occurs in this area.

[0056] Working principle: First, the user pushes the device to the detection area through the push handle 7, and limits the rotation direction of the Y-shaped bracket 8 through the cooperation with the baffle 10. The Y-shaped bracket 8 and the driving wheel 9 are used to assist the movement of the device. When the bottom plate 1 is not parallel to the plane to be detected, turn the knobs 302 on both sides of the device in sequence. When the knob 302 rotates, it will drive the threaded rod 301 connected to it to rotate synchronously. During the rotation of the threaded rod 301, the slider 303 will slide along the dovetail groove 201. When the slider 303 slides upward, the connecting rod 305 will tend to open. At this time, under the action of the traveling wheel 306, one side of the device will be correspondingly lowered. On the contrary, when the slider 303 slides downward, the connecting rod 305 will gradually close, thereby raising one side of the device. During the whole adjustment process, it is necessary to closely monitor the working state of the infrared detection module 505. When the specific wave emitted by the infrared emitter in the infrared detection module 505 can be successfully received by the infrared receiver, it indicates that the bottom plate 1 is already precisely parallel to the plane to be detected. At this time, the adjustment operation can be stopped;

[0057] During the process of moving the device by pushing the push handle 7, if an abnormal inclination occurs in a certain area, the part at the front end of the device and below the bottom plate 1 will come into contact with the abnormal area first. Since the support frame 501 is fixedly connected to the inner wall of the cavity box 4 and is also connected to the connecting rod 502 in a rotatable manner, the whole front end of the device will tilt to one side, driving the cavity box 4 to tilt accordingly. The push handle 7 and the connecting rod 502 fixedly connected thereto will not tilt. In this way, the tilted side of the cavity box 4 will cause the infrared transmitter or infrared receiver on the L-shaped extension plate 504 originally located on that side to gradually retract into the cavity box 4 through the notch 401, and the infrared receiver will not be able to receive the signal emitted by the infrared transmitter. Thus, it can be judged whether there is an abnormal inclination in the area to be detected;

[0058] When the control module 11 detects an abnormality in the infrared detection module 505, the driving motor 1303 is started. The driving motor 1303 drives the turntable 1304 to rotate, drives the column 1308 to slide in the through groove 1307, and drives the rectangular strip 1306 to swing reciprocally through the cooperation of the rotating rod 1305. The rectangular tooth plate 1310 is driven to slide linearly and reciprocally outside the L-shaped mounting plate 1302 through the sector gear plate 1309, so as to drive the impact block 1311 to impact the frame 6 frequently, and effectively remind the user of the abnormal inclination in this area through the transmission of the push handle 7;

[0059] Since the bottom plate 1 is already parallel to the detection plane through the adjusting mechanism 3, several detection wheels 1403 are always in contact with the detection plane under the thrust of the thrust spring 1402. When the push handle 7 moves the device and a pitted area appears, several sliding rods 1401 will slide in the outer chute of the bottom plate 1. When the corresponding detection wheel 1403 touches a ground protrusion in a certain area, the sliding rod 1401 drives the limiting plate 1404 to slide upward. When the corresponding detection wheel 1403 touches a ground depression in the area, the sliding rod 1401 drives the limiting plate 1404 to slide downward. During the movement of the device, it is only necessary to check in real time whether the heights of several sliding rods 1401 are consistent, so as to visually check the flatness of the area to be detected. And when the heights of several sliding rods 1401 tilt to one side, it can also be judged that there is an abnormal inclination in this area.

[0060] The embodiments of the present invention are given for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
