Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to an acceptance device for construction engineering based on wireless transmission technology. Background Art

[0002] Construction projects refer to the planning, investigation, design, construction, completion and other technical work and completed engineering entities for the construction, reconstruction or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines and equipment. They also refer to the construction projects of various houses and buildings, also known as construction workload. This part of the investment must be started and materials moved, and can only be realized through construction activities. Among them, the construction projects of "buildings" include factories, theaters, hotels, shops, schools, hospitals and residences, etc., whose new construction, reconstruction or expansion must be started and materials moved, and can only be realized through construction activities; "ancillary structures and facilities" refer to water towers, bicycle sheds, pools, etc. that are matched with buildings, and "installation of lines, pipelines and equipment" refers to the installation activities of electrical, water supply and drainage, HVAC, communications, intelligence, elevators and other lines, pipelines and equipment that are matched with buildings and their ancillary facilities.

[0003] After the construction of a building project is completed, a detection device is needed for acceptance, which includes testing the flatness of the wall. A flatness tester is needed when testing the flatness of the wall.

[0004] At present, when inspecting the wall, the inspectors are usually required to inspect every position of the wall. However, as for the current traditional acceptance devices for construction projects, such as CN218270628U, a wall acceptance device for construction projects, by turning on the laser lamp to emit laser, observing whether the laser irradiated by the laser lamp on the outer wall of the base is directly irradiated on the reflective plate through the through hole, it can be concluded that there is unevenness between the oblique areas of the wall, thereby improving the accuracy of the wall flatness detection. However, the method of observing whether the wall is flat by a laser passing through the through holes of multiple pressure rods is not practical. If there are bumps on the wall, the through hole of one pressure rod is not connected to the other through holes, resulting in the laser beam being blocked, and it is impossible to understand whether the multiple pressure rods behind are flat with the wall. It can only be measured that there are bumps on the wall in a certain area. The area behind the light blocking needs to be re-inspected, which increases the acceptance time, poor acceptance efficiency, and increased labor intensity of operators, and poor practicality.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0033] The present invention provides a construction project acceptance device based on wireless transmission technology, referring to Figure 1-Figure 5 ,include:

[0034] Mounting plate 1;

[0035] Four support columns 2 are fixedly installed on one side of the mounting plate 1, respectively. A testing device 3 is also fixedly installed in the middle of the mounting plate 1, and a squeezing device 4 is slidably provided on the front side of the testing device 3;

[0036] The electric control board 5 is fixedly mounted in the middle of the mounting plate 1 on the side away from the support column 2, and a numerical plate 6 is arranged on the surface of the electric control board 5;

[0037] A data transmission device 8 is provided on one side of the electric control board 5 through electric wires, an alarm device 9 is provided on the other side of the electric control board 5 through electric wires, and a power line 10 is provided on the surface of the electric control board 5; and

[0038] Two grip rods 7 are fixed in parallel on a side of the mounting plate 1 away from the support column 2 .

[0039] When inspecting the wall of a construction project, the operator holds the handle 7 and moves the device close to the wall so that the four support columns 2 are in contact with the wall. At this time, the initial position of the extrusion device 4 is close to the wall but no pressure has been applied. When the operator places the device stably on the wall, the extrusion device 4 will come into contact with the wall and receive the reaction force of the wall. Since the extrusion device 4 is slidably arranged on the front side of the test device 3, under the action of the reaction force of the wall, the extrusion device 4 will slide backward relative to the test device 3. During this sliding process, the relevant mechanism inside the test device 3 will be triggered to detect the magnitude of the force received by the extrusion device 4 and other information. The testing device 3 converts the force information into an electrical signal or other quantifiable data, which will be transmitted to the electric control board 5. The circuit and related processing modules in the electric control board 5 will process the data. The processed results will be displayed on the numerical board 6 on the one hand, so that the operator can directly view the test data on site; on the other hand, the data will be transmitted to the data transmission device 8. The modules in the data transmission device 8 (such as the signal conversion, encoding and other modules that may be included) will process the data, and then send the data to an external mobile terminal or other receiving device through wireless transmission technology (such as 4G or other wireless communication protocols). During the detection process, the alarm device 9 will continuously monitor the data on the numerical board 6. If the value is abnormal, such as exceeding the pre-set normal range, this may mean that there is some non-standard situation on the wall, such as excessive deviation in the flatness of the wall or insufficient structural strength. The alarm device 9 will issue an alarm signal based on these abnormal data, such as a buzzer or flashing lights, to remind the operator to pay attention to the detected abnormal situation.

[0040] The device can detect multiple points on the wall by arranging multiple test devices 3 and corresponding extrusion devices 4 on the mounting plate 1. This multi-point detection method can more comprehensively reflect the overall situation of the wall. Compared with the single-point detection method, it can more accurately find local problems on the wall, such as small-area depressions or protrusions, thereby improving the accuracy of the wall acceptance of the construction project. The overall structural design of the device takes into account the convenience of operation. The two gripping rods 7 are convenient for the operator to hold, making it easier to operate when the device is close to and fits the wall. In addition, the layout of the entire device is reasonable, and the connection and collaborative working methods between the various components are simple and clear. It does not require complicated operating procedures and professional skills. Ordinary operators can skillfully use the device to perform wall detection after simple training. The existence of the data transmission device 8 enables the detection data to be transmitted to the external device in a timely manner, which is very beneficial to the multiple parties involved in the construction project (such as the construction party, the supervision party, the owner, etc.). They can obtain the detection data in real time through the mobile terminal or other receiving devices, and can understand the detection status of the wall even if they are not at the detection site. This remote monitoring capability helps to improve the management efficiency of the construction project, find problems in time and make decisions. The setting of the alarm device 9 can timely find abnormal conditions in the detection data and issue an alarm, which helps the operator to find possible problems with the wall at the first time, so that further inspection or repair measures can be taken in time, avoiding the occurrence of subsequent construction delays or quality risks due to failure to find problems in time, and ensuring the quality and progress of the construction project.

[0041] Specifically, refer to Figure 3 The test device 3 includes a fixed column 31, a movable groove 32, a fixed rod 33, a spring 34, an extrusion force measuring device 35 and a limit block 36, wherein: the fixed column 31 is fixed on the mounting plate 1, the movable groove 32 is opened in the fixed column 31, and the extrusion force measuring device 35 is fixedly installed on the rear side of the inner cavity wall of the movable groove 32; the fixed rod 33 is fixedly installed in the middle of the rear side of the inner cavity wall of the movable groove 32, the spring 34 is sleeved on the outer surface of the fixed rod 33, and one end of the spring 34 is fixedly connected to the surface of the extrusion force measuring device 35, and the limit block 36 is fixedly installed on the front end of the fixed rod 33.

[0042] First, the fixed column 31 is firmly fixed on the mounting plate 1, providing a stable support foundation for the entire test device 3. The movable groove 32 is opened in the fixed column 31. This structure provides space for the installation and movement of subsequent components. An extrusion force measuring device 35 is fixedly installed on the rear side of the inner cavity wall of the movable groove 32. The extrusion force measuring device 35 is a key component for detecting the size of the extrusion force. The fixed rod 33 is fixedly installed in the middle position of the rear side of the inner cavity wall of the movable groove 32. Its main function is to provide guidance and support for the spring 34 and other related components. The spring 34 is sleeved on the outer surface of the fixed rod 33. , one end is fixedly connected to the surface of the extrusion force measuring device 35, and the limit block 36 is fixed to the front end of the fixed rod 33. When the extrusion device 4 is subjected to external force (such as the reaction force from the wall), the extrusion device 4 will apply pressure to the spring 34. Since the spring 34 is sleeved on the fixed rod 33, the spring 34 can only be compressed or stretched along the axial direction of the fixed rod 33; when the spring 34 is squeezed, it will transfer the force to the extrusion force measuring device 35; after receiving the force transmitted by the spring 34, the extrusion force measuring device 35 will measure the force according to its internal working principle. For example, it may be based on the principle of strain gauge. When subjected to force, the strain gauge will deform, causing its resistance value to change; according to the electrical principle, by measuring the current or voltage changes in the circuit, the magnitude of the force applied to the strain gauge, that is, the magnitude of the extrusion force applied by the extrusion device 4, can be calculated. The limit block 36 exists to limit the range of motion of the spring 34 and moving parts (such as parts related to the extrusion device 4). When the spring 34 is compressed to a certain extent, the limit block 36 will prevent the related parts from continuing to move, preventing excessive compression of the spring 34 and causing damage to the device. At the same time, it also ensures that the extrusion force measuring device 35 operates within its designed measurement range.

[0043] Reference Figure 3 The extrusion device 4 includes a moving block 41, a sliding hole 42, a limiting cavity 43 and an extrusion plate 44, wherein: the moving block 41 is slidably installed inside the moving groove 32, the end of the spring 34 away from the extrusion force measuring device 35 is fixedly connected to the surface of the moving block 41, the sliding hole 42 is opened in the middle of the rear side of the moving block 41; the limiting cavity 43 is opened inside the moving block 41, the fixing rod 33 passes through the sliding hole 42 and extends into the limiting cavity 43, and the limiting block 36 is slidably connected to the limiting cavity 43; the extrusion plate 44 is fixedly installed on the front side of the moving block 41.

[0044] When the device is used for wall detection in construction projects, the extrusion plate 44 first contacts the wall. Since the extrusion plate 44 is fixedly installed on the front side of the moving block 41, when there are concave-convex conditions on the wall or the device is pressed against the wall, the extrusion plate 44 will be subjected to force from the wall, and this force will directly act on the moving block 41. Since the moving block 41 and the extrusion plate 44 are a fixedly connected whole, and the moving block 41 is slidably installed inside the moving groove 32, after receiving the force transmitted by the extrusion plate 44, the moving block 41 will produce a sliding displacement in the moving groove 32. The end of the spring 34 away from the extrusion force measuring device 35 is fixedly connected to the surface of the moving block 41, so the sliding of the moving block 41 will produce a stretching or compressing effect on the spring 34. For example, when the extrusion plate 44 is pushed by the wall, the moving block 41 will move toward the fixed column 31, thereby compressing the spring 34; when there is a depression in the wall and the reaction force on the extrusion plate 44 is reduced, the spring 34 may make the moving block 41 tend to move in the opposite direction due to its own elastic potential energy; the sliding hole 42 is opened in the middle of the rear side of the moving block 41, the fixed rod 33 passes through the sliding hole 42 and extends into the limiting cavity 43, and the limiting block 36 is slidably connected to the limiting cavity 43. This structural design allows the sliding of the moving block 41 in the moving groove 32 to be carried out along the direction of the fixed rod 33, and the fixed rod 33 plays a guiding role. The cooperation between the limiting cavity 43 and the limiting block 36 further limits the moving range of the moving block 41, prevents the moving block 41 from being offset or excessively moved during the sliding process, and ensures the stability and predictability of the movement of the moving block 41. In the whole process, the forces generated by the sliding of the moving block 41 and the deformation of the spring 34 are interrelated. According to Newton's third law, the force applied by the extrusion plate 44 to the wall is equal in magnitude and opposite in direction to the reaction force exerted by the wall on the extrusion plate 44. This reaction force is transmitted to the moving block 41 through the extrusion plate 44, and then affects the state of the spring 34 through the connection between the moving block 41 and the spring 34. The degree of deformation of the spring 34 is proportional to the force it receives (within the elastic limit), and the force received by the spring 34 is related to the reaction force of the wall received by the extrusion plate 44. Therefore, by measuring the deformation or force of the spring 34 (completed by the extrusion force measuring device 35), the extrusion force of the extrusion plate 44 on the wall can be indirectly obtained, thereby judging the flatness and other characteristics of the wall.

[0045] Reference Figure 1-Figure 2, there are thirty-six test devices 3 and extrusion devices 4 respectively, and one test device 3 and one extrusion device 4 form a group. When conducting wall inspection of construction projects, these thirty-six groups are evenly distributed on the mounting plate 1, and can conduct a more comprehensive inspection of the wall; when the device contacts the wall, the extrusion plate 44 of each extrusion device 4 will be subjected to reaction forces from different positions of the wall. Since each extrusion device 4 is connected to a test device 3, the force received by each extrusion plate 44 will be transmitted to the corresponding test device 3 through the corresponding extrusion device 4; in each test device 3, the extrusion force measuring device 35 will measure the extrusion force received by the group of extrusion devices 4. There are thirty-six numerical boards 6, and they correspond to the extrusion force measuring devices 35 one by one. Each extrusion force measuring device 35 will transmit the measured data to a numerical board 6 for display, so as to ensure that the measurement data of each extrusion force measuring device 35 has a dedicated numerical board 6 for display. For example, the test-extrusion device group 4 located at the upper left corner of the mounting plate 1, after its extrusion plate 44 is subjected to the reaction force of the wall, transmits the force to the corresponding extrusion force measuring device 35 through the internal structure. This measuring device transmits the measured value to the corresponding numerical plate 6 in the upper left corner. This corresponding relationship ensures that the extrusion pressure data collected from various positions on the wall can be accurately displayed on the corresponding numerical plates 6.

[0046] The data transmission device 8 is internally installed with a microprocessor and a 4G module, and the microprocessor and the 4G module are electrically connected, and the microprocessor is connected to the numerical board 6, so that during the detection, the numerical board 6 transmits the detection information to the microprocessor, and then the microprocessor transmits the signal to the mobile terminal through the 4G module. During the detection process, the thirty-six numerical boards 6 will continue to display the extrusion force numerical information of each test-extrusion device 4 group, and the numerical board 6 transmits these detection information to the microprocessor. The microprocessor, as a data processing center, will sort and convert the received numerical information. For example, the numerical value in the form of an analog signal may be converted into a digital signal for subsequent transmission and processing; then, the microprocessor transmits the processed signal to the mobile terminal through the 4G module, and the 4G module uses 4G network communication technology to send the signal from the microprocessor wirelessly; after receiving these signals, the mobile terminal (such as a mobile phone, a tablet computer, etc.) can display, analyze and store the data through the corresponding software; in this way, the data at the detection site can be transmitted to the remote device in real time, which is convenient for relevant personnel (such as engineering management personnel, owners, etc.) who are not on site to understand the detection situation in a timely manner.

[0047] The alarm device 9 is electrically connected to the numerical board 6 to detect the numerical information in the thirty-six numerical boards 6. Under normal circumstances, when the wall surface is relatively uniform, the extrusion pressure values ​​displayed by the thirty-six numerical boards 6 should fluctuate within a certain reasonable range, and the differences between them are small. However, when there are abnormal conditions on the wall surface (such as local protrusions, depressions, or uneven structural strength, etc.), the values ​​on the corresponding numerical boards 6 will change, resulting in differences in the numerical information displayed by the thirty-six numerical boards 6. A comparison and judgment circuit is provided inside the alarm device 9. When it is detected that the numerical difference exceeds a pre-set threshold, the alarm mechanism will be triggered and a buzzer will sound. This threshold can be set according to the specific acceptance standards and requirements of the construction project to ensure that possible problems with the wall surface can be discovered in a timely manner.

[0048] The surface of the grip 7 is provided with anti-slip grooves. The surface of the grip 7 is provided with anti-slip grooves. When the operator holds the grip 7 to operate the acceptance device, the anti-slip grooves can effectively prevent the hand from slipping off the grip 7. The increase in friction is achieved through the special texture of the anti-slip grooves. For example, the anti-slip grooves may be some staggered grooves or protrusions, which increase the contact area between the hand and the surface of the grip 7 and make the contact between the hand and the grip 7 closer, thereby improving the stability and safety of holding.

[0049] Reference Figure 4-Figure 5 A limiting hole 18 is provided on one side of the top of the mounting plate 1, and a threaded hole 17 is provided on the other side of the top of the mounting plate 1. A limiting rod 11 is sleeved inside the limiting hole 18, and a fixing plate 12 is fixedly installed on the top and bottom ends of the limiting rod 11; a servo motor 14 is fixedly installed on one side of the top of one of the fixing plates 12, and a reciprocating screw rod 15 is fixedly connected to the bottom end of the output shaft of the servo motor 14, and the reciprocating screw rod 15 is threadedly connected to the threaded hole 17. When the height of the mounting plate 1 needs to be adjusted (for example, to detect walls of different heights), the servo motor 14 is started, and the output shaft of the servo motor 14 drives the reciprocating screw 15 to rotate. Since the reciprocating screw 15 is threadedly connected to the threaded hole 17, when the reciprocating screw 15 rotates, the mounting plate 1 will move up and down along the limit rod 11. The limit rod 11 passes through the limit hole 18, which guides and limits the moving direction of the mounting plate 1, ensuring that the mounting plate 1 remains stable during the up and down movement. The height of the mounting plate 1 is adjusted, and the acceptance device is conveniently slid on the wall through the moving wheel 16 to adjust the detection position. The device has a simple structure and strong practicality. The operator can control the acceptance device to arbitrarily adjust the detection position on the wall, thereby enhancing the flexibility and practicality of the device.

[0050] Reference Figure 4-Figure 5 The surface of the fixing plate 12 is fixedly mounted with suction cups 13. When the mounting plate 1 is moved to a suitable position, the suction cups 13 can be adsorbed on a wall or other supporting structure to further fix the position of the mounting plate 1, thereby ensuring the stability of the device during the detection process.

[0051] Implementation principle: When working, firstly, thirty-six test devices 3 and extrusion devices 4 are arranged on the surface of the mounting plate 1, and the thirty-six test devices 3 and extrusion devices 4 form a square and fit on the detection wall. The user holds the grip 7 to fit the four support columns 2 on the wall surface, and the thirty-six extrusion plates 44 approach the wall. If the wall is flat, the thirty-six extrusion plates 44 are all fitted on the wall, and the extrusion plates 44 are squeezed by the wall and move toward the side of the fixed column 31. The extrusion plates 44 drive the moving block 41 to move inside the moving groove 32, and the moving block 41 passes through the sliding hole 42 along the The fixed rod 33 slides, and the moving block 41 squeezes the spring 34. The spring 34 squeezes toward the side of the extrusion force measuring device 35, so that the extrusion measuring device detects the value of the extrusion force and transmits the value to the value board 6 for display as a value; the operator can observe the pressure values ​​displayed on the thirty-six value boards 6. If the wall surface is flat, the thrust values ​​of the thirty-six extrusion measuring devices received by the spring 34 are the same. If there is a concave or convex situation somewhere on the wall surface, the pressure value will be lower or higher than most of the same values, thereby distinguishing whether there is a concave or convex situation somewhere on the wall surface.

Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
