Description

Technical Field

[0001] The invention relates to the technical field of measurement, and in particular to a construction measurement device. Background Art

[0002] Construction measurement devices are mainly used to ensure the accuracy and safety of construction projects. Common devices include total stations, levels, laser rangefinders and levels. These tools help engineers and surveyors accurately measure distances, heights and angles during the construction process to ensure that the construction structure meets the design requirements. For example, a super high-rise building engineering measurement device disclosed in a Chinese patent with publication number CN115218867B.

[0003] In order to improve the accuracy and reliability of measurement data and avoid the initial measurement results being affected by environmental factors, equipment errors or improper operation, existing construction measurement devices need to perform multiple intermittent repeated measurements to correct potential errors and ensure the consistency of results. In order to reduce the error of the measurement device when measuring at the same position during repeated measurements, it is necessary to ensure that the position and height of the measurement device are consistent with the initial measurement when measuring the same position again. Existing construction measurement devices usually use manual recording for the data during the initial measurement. Manual recording often lacks precise identification or coordinate systems, which can easily cause deviations in subsequent measurements. At the same time, different personnel have different recording methods, resulting in differences in data format and content, which causes different personnel to make different judgments on the data, and then leads to differences in measurement position and height, affecting the accuracy of the re-measurement. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a construction measurement device, which can effectively solve the problem that the prior art often lacks accurate identification or coordinate system through manual recording, which is easy to produce deviations in subsequent measurements and affect the accuracy of the re-measurement.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a construction measurement device, comprising:

[0007] A protection box, wherein the four corners of the bottom of the protection box are provided with electrically controlled universal wheels, the top of the protection box is fixedly connected with a mounting platform, the top of the mounting platform is provided with a measuring mechanism for building construction measurement, the protection box is symmetrically provided with a push handle and a panoramic camera on both sides, the grip of the push handle is provided with a controller, and the panoramic camera is electrically connected to the controller;

[0008] A marking mechanism, the marking mechanism comprises a shell vertically slidably connected to the center of the bottom of the protection box, a liquid dispensing assembly for transmitting the pigment required for marking is arranged on the inner top of the shell, a liquid storage assembly for storing the pigment is arranged on the inner bottom of the shell and at the corresponding position of each liquid dispensing assembly, a volume detection assembly for detecting the amount of pigment is arranged in the inner middle of the liquid storage assembly, an arrangement block penetrating the inner bottom of the protection box is fixedly connected to the bottom of the shell, a plurality of marking assemblies for printing two-dimensional codes and four positioning blocks for locating the printing position of the two-dimensional code are fixedly connected to the lower end of the arrangement block in a matrix arrangement, the four positioning blocks are located at the four corners of the arrangement block, and the printing patterns of the four positioning blocks are inconsistent, and the liquid storage assembly corresponds one to one with the positioning blocks and the marking assembly;

[0009] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0010] 1. The construction measurement device realizes the pretreatment of the pigment liquid required when the positioning block and the marking component in the marking mechanism form a two-dimensional code mark through the liquid separation component, the liquid storage component and the volume detection component in the marking mechanism, so as to ensure that the two-dimensional code mark formed by the positioning block and the marking component is clear when it is sprayed on the ground, thereby improving the subsequent scanning of the two-dimensional code mark. Among them, the liquid separation component can perform diversion processing on the pigment liquid, so as to achieve the purpose of diverting the pigment liquid to the liquid storage components at different positions, and the liquid storage component can temporarily store the pigment liquid transmitted by the liquid separation component, thereby It is convenient for the positioning blocks and marking components at various positions to obtain pigment liquid as needed, and a volume detection component for detecting the amount of pigment liquid in the current liquid storage component is provided in the liquid storage component. The volume detection component can be used to judge the amount of pigment liquid in the liquid storage component in real time, thereby realizing the replenishment of the pigment liquid in the liquid storage component. By diverting and storing the pigment liquid, it can ensure rapid supply when needed, avoiding waste of pigment liquid. In addition, the real-time monitoring function of the volume detection component can replenish the pigment liquid in time, ensure the stable operation of the system and the marking quality, and ultimately improve the overall work efficiency and readability of the marking data.

[0011] 2. The construction measurement device, through the positioning block and the marking component in the marking mechanism, realizes forming a two-dimensional code mark from the data measured by the measurement device, and prints the two-dimensional code mark on the ground at the detection position, wherein the positioning block is mainly used to record the orientation of the measurement device when printing the two-dimensional code mark, and the marking component is mainly used to form a two-dimensional code mark containing the measurement data, and prints the two-dimensional code mark on the ground, so that when the measurement device measures the same position again, the device can obtain the measurement state of the measurement device during the previous measurement (measurement state: the position, height, measurement time, etc. of the measurement device) by scanning the two-dimensional code mark at this position, so that the measurement device can perform self-correction according to the data in the two-dimensional code mark, so that the device can restore the same state as the previous measurement to the greatest extent, thereby reducing the error during the re-measurement, and using the two-dimensional code mark to record the previous measurement state information, the measurement device can quickly self-correct, thereby reducing errors and deviations. At the same time, this method also improves work efficiency, avoids the time cost of repeatedly setting up equipment, ensures the traceability and data reliability of each measurement, and helps to make more accurate analysis and decision-making.

[0044] The volume detection component 36 is used to detect the amount of pigment liquid in each liquid storage barrel 351 in real time, so as to replenish the pigment liquid in the liquid storage barrel 351 in time, thereby avoiding unclear QR code printing due to insufficient pigment liquid.

[0047] Reference Figures 13 to 15 , also includes a cleaning scanning mechanism 4, the cleaning scanning mechanism 4 includes four cleaning shells 41 fixedly connected to the four side edges of the bottom of the protective box 1, each of the cleaning shells 41 is fixedly connected to a partition plate 411 and two partition plates 412, the partition plate 411 and the partition plate 412 constitute two dust collecting areas and two dust suction areas in the cleaning shell 41, the two dust collecting areas are located in the middle of the cleaning shell 41, and the two dust suction areas are located on both sides of the two dust collecting areas, and the length of the dust collecting area is greater than the length of the dust suction area, the inner bottom linear array of the dust collecting area is rotatably connected to a plurality of stirring rods 45, the inner wall linear array of the dust collecting area is fixedly connected to a plurality of airflow tubes 44, and the end of the airflow tube 44 away from the partition plate 411 passes through the partition plate 412 and is connected to the dust suction area, and the airflow tube 44 faces the outer shell 31 A plurality of air holes are opened in a linear array on the body, the cleaning shell 41 faces the outside of the outer shell 31 and is fixedly connected with a plurality of inclined suction nozzles 42 in a linear array at corresponding positions in the dust collecting area, and the inclined direction of the inclined suction nozzles 42 faces the ground, and a scanner 43 is fixedly connected to the bottom of the cleaning shell 41, and a conduit 46 is fixedly connected to the outsides of adjacent cleaning shells 41, and the conduit 46 penetrates the cleaning shell 41 through a pipeline and is connected to the dust collecting area, and every two adjacent conduits 46 are fixedly connected with a transmission pipe 47, and a first communicating vessel 48 is fixedly connected to the inner wall of the protective box 1, and the first communicating vessel 48 is connected to the conduit 46 through the transmission pipe 47, and a vacuum cleaner 49 is fixedly connected to the side of the protective box 1, and the vacuum cleaner 49 corresponds to the position of the first communicating vessel 48 and is connected through a pipeline.

[0048] By using the cleaning shell 41, tilted suction nozzle 42 and stirring rod 45 in the cleaning scanning mechanism 4, the ground can be cleaned before the marking mechanism 3 prints the QR code, thereby removing the dust on the ground where the QR code is printed to the greatest extent, thereby improving the clarity of the QR code printed on the ground by the marking mechanism 3.

[0049] The operating principle of this embodiment is as follows:

[0050] Step 1: First, the controller 14 controls the electric universal wheel 11 (the electric universal wheel 11 is the prior art) to drive the device to move to the position to be detected (the position to be detected in the present invention defaults to the initial measurement position). When the device reaches the position to be detected, the controller 14 can adjust the lifting frame 21 and the pan-tilt head 24 in the measuring mechanism 2, so that the laser measuring instrument 25 arranged on the lifting frame 21 and the pan-tilt head 24 can reach the optimal height and direction for measuring this detection position (during the initial measurement, the laser measuring instrument 25 adjusts the height and direction of the position to be detected manually through the controller 14, because experienced personnel can make more reasonable judgments based on the on-site conditions, select the best measurement strategy, and quickly adjust according to feedback information to ensure that each measurement is in the best state and improve the reliability of the results).

[0051] Among them, after the manual adjustment of the laser measuring instrument 25 is completed through the lifting frame 21 and the pan / tilt 24, the laser measuring instrument 25 starts to measure the position to be detected, and at the same time, transmits the measurement data to the controller 14, and the manual will first judge the detection data transmitted by the laser measuring instrument 25 through the controller 14 (the manual judgment here means that the manual judges whether the detection data transmitted by the laser measuring instrument 25 has a large error through experience), and when the manual judgment of the detection data transmitted by the laser measuring instrument 25 is completed, if the manual believes that the detection data transmitted by the laser measuring instrument 25 does not meet the normal detection range, the manual will make the laser measuring instrument 25 re-detect through the controller 14 until the manual believes that there is no problem with the detection data, the controller 14 will convert the detection data transmitted by the laser measuring instrument 25 into two-dimensional code format data, and transmit the two-dimensional code data to the marking mechanism 3, so that the marking mechanism 3 prints the corresponding two-dimensional code on the ground at the detection position according to the received two-dimensional code data, and the panoramic camera 15 will also synchronously take pictures of the detection position as a basis for auxiliary judgment during the next detection.

[0052] Step 2: Of course, after the marking mechanism 3 receives the QR code data transmitted by the controller 14, the cleaning scanning mechanism 4 will be started first, so as to clean the dust and impurities on the ground where the QR code is printed by the marking mechanism 3;

[0053] When the cleaning scanning mechanism 4 is manually started through the controller 14, the vacuum cleaner 49 in the scanning mechanism 4 will be started first, and the suction generated by the vacuum cleaner 49 will be distributed to the transmission pipes 47 on both sides of the flow through the first connecting vessel 48, and the transmission pipe 47 will further transmit the suction to the confluence 46, and then the suction transmitted to the confluence 46 will enter the dust suction area in the two adjacent cleaning shells 41 connected thereto, so that the suction is gathered in the dust suction area, and the suction gathered in the dust suction area will enter the airflow pipe 44, as the suction enters the airflow pipe 44, the suction also absorbs the air in the dust collection area through the pores in the airflow pipe 44, so that negative pressure appears in the dust collection area, and then the air in the dust collection area is continuously reduced, and the dust collection area starts to absorb air from the outside through the inclined suction nozzle 42, and the inclination angle of the inclined suction nozzle 42 is the ground where the marking mechanism 3 prints the two-dimensional code, so when the inclined suction nozzle 42 starts to absorb air from the outside, it also starts to clean the impurities in the ground where the two-dimensional code is printed.

[0054] Among them, as the impurities are continuously sucked through the inclined suction nozzle 42, the rotating stirring rod 45 begins to break up the impurities sucked into the dust collecting area (the power for the rotation of the stirring rod 45 comes from the suction force in the airflow tube 44), thereby avoiding blockage of the impurities in the confluence 46, the transmission tube 47 and the first connecting vessel 48 during the process of being transmitted to the vacuum cleaner 49.

[0055] Thus, the dust and impurities on the ground where the QR code is printed are cleaned by cleaning the scanning mechanism 4, and the start of the scanner 43 in the cleaning scanning mechanism 4 is controlled by the controller 14, so the scanner 43 is not started by default at this time (when there is a QR code at the detection position, the scanner 43 needs to be manually started and confirmed in the controller 14).

[0056] Step 3: When the cleaning scanning mechanism 4 completes the cleaning of impurities on the ground where the QR code is printed, and the marking mechanism 3 also receives the QR code data transmitted by the controller 14, the pigment delivery component 3102 in the marking mechanism 3 will be started first (the pigment delivery component 3102 is composed of a pigment storage bin, a pigment pump and a command executor), so that the pigment liquid stored in the pigment delivery component 3102 is transmitted to the delivery pipe 310 through the second connecting vessel 3101, and the pigment liquid transmitted to the delivery pipe 310 is further transmitted to the diverter 33. At this time, the diverter 33 will further divert the pigment liquid transmitted to the delivery pipe 310, and transmit the diverted pigment liquid through the diverter pipe 331 to the main infusion pipe 342 in the liquid separation component 34.

[0057] When the pigment liquid is transferred to the main infusion pipe 342, the main infusion pipe 342 starts to transfer the pigment liquid to the three-way valves 341 at various positions, and the three-way valve 341 transfers the pigment to the corresponding liquid storage barrel 351 through the pipeline at the output end, and the three-way valve 341 can realize the diversion of the pigment liquid transferred by the main infusion pipe 342, so as to realize the control of the amount of pigment liquid in the liquid storage barrel 351 transferred to the liquid storage component 35 by the three-way valve 341 through the infusion branch pipe 343, and the opening and closing of the three-way valve 341 is controlled by the volume detection component 36 (note: the two ports of the main infusion pipe 342 of the three-way valve 341 are always connected, and the other port of the three-way valve 341 is controlled to open and close, so that the three-way valve 341 transfers pigment to the spherical diverter 344 through the pipeline);

[0058] When the pigment liquid enters the liquid storage barrel 351 through the three-way valve 341, as the pigment liquid is continuously injected into the liquid storage barrel 351, the pigment liquid stored in the liquid storage barrel 351 is also continuously increased, thereby causing the liquid storage barrel 351 to expand. As the liquid storage barrel 351 expands, the telescopic ring 352 also begins to extend, thereby increasing the volume of the pigment liquid stored in the liquid storage barrel 351, and the volume detection component 36 provided in the liquid storage barrel 351 is used to detect the amount of pigment liquid stored in the liquid storage barrel 351, thereby controlling the opening and closing of the three-way valve 341, thereby ensuring that the amount of pigment liquid stored in the liquid storage barrel 351 is sufficient, thereby avoiding the phenomenon that the printed QR code is not clearly printed due to insufficient pigment liquid in some areas during the subsequent printing of the QR code, thereby causing the scanner 43 to be unable to recognize the QR code when scanning it, resulting in the inability to obtain data (QR code The reason why data cannot be obtained due to unclear printing: The QR code is composed of black and white modules (the black and white modules can also be modules of other two different colors). These modules transmit information. If the QR code is blurred or damaged due to insufficient pigment during printing, it is difficult for the scanning device to accurately identify each module, resulting in reading failure or error. Due to the limited fault tolerance of the QR code, the blurred part will exceed its repairable range, so sufficient color is required when printing the QR code. When the QR code has sufficient color, it means that the pigment layer is thicker. In outdoor environments, a thicker pigment layer can provide better physical protection for the QR code, thereby reducing the possibility that the QR code will be blurred or damaged due to human or environmental factors, which exceeds the fault tolerance of the QR code, and improves the reading accuracy when the device scans the QR code again).

[0059] Among them, the float structure 363 in the volume detection component 36 will rise along the detection column 361 as the pigment liquid stored in the liquid storage barrel 351 continues to increase. The float structure 363 is affected by the buoyancy of the pigment liquid and rises. When the float structure 363 rises to the top of the detection column 361, the spring 362 in the detection column 361 will be compressed (the spring 362 is a weak elastic spring. At the same time, the buoyancy provided by the pigment to the float structure 363 is sufficient to compress the spring 362. Therefore, when the float structure 363 is affected by the buoyancy provided by the pigment, the float structure 363 will rise to the top of the detection column 361. After that, the float structure 363 will compress the spring 362. When the pigment is not enough to provide the float structure 363 with the buoyancy to compress the spring 362, the spring 362 will release the compression force, thereby restoring the float structure 363 to its original position). The impact rod 3634 in the float structure 363 will collide with the collision switch at the top of the detection column 361 (the collision between the impact rod 3634 and the inner top collision switch indicates that the pigment liquid stored in the liquid storage barrel 351 has reached the maximum value). When a collision occurs, the three-way valve 341 is closed, and the pigment liquid stored in the main infusion pipe 342 no longer delivers the pigment liquid to the liquid storage barrel 351. When the pigment liquid stored in the liquid storage barrel 351 is continuously reduced due to printing, the buoy structure 363 begins to descend along the detection column 361 (after the collision switch at the top of the detection column 361 is separated from the impact switch, the three-way valve 341 will not open, because the impact switch at the top of the detection column 361 is a one-way switch that can only close the three-way valve 341, but cannot open the three-way valve 341). ), at this time, the impact rod 3634 in the float structure 363 will collide with the collision switch at the bottom of the detection column 361 (the collision of the impact rod 3634 with the inner bottom collision switch indicates that the pigment liquid stored in the liquid storage barrel 351 is lower than the minimum value), and when the impact rod 3634 collides with the inner bottom collision switch, the three-way valve 341 opens, and the pigment liquid stored in the infusion main pipe 342 is re-injected into the liquid storage barrel 351, and the spring 362 can maintain the stability of the float structure 363 sliding in the detection column 361.

[0060] When the liquid storage component 35 completes the storage of the pigment liquid, the liquid storage component 35 will transfer the pigment liquid to the positioning block 38 and the marking component 39 at the corresponding position through the connecting pipe 353 and the annular connecting seat 354;

[0061] The positioning block 38 is printed on the ground each time it is marked, because the positioning block 38 can record the state of the measuring device when the measuring device first measures by using its different marking patterns, so that when the measuring device measures again, the measuring device can obtain the state data of the measuring device during the previous measurement according to the positioning block 38, so that the measuring device can perform self-correction according to the obtained state data, so that the device can be restored to the same state as the previous measurement to the greatest extent, thereby reducing the error during the re-measurement;

[0062] After the marks 392 in the different position marking components 39 receive the two-dimensional code data transmitted by the controller 14, the controller 14 simultaneously passes current into the corresponding electromagnet 393, so that the electromagnet 393 generates magnetism, and the electromagnet 393 repels the permanent magnet in the marks 392, so that the marks 392 slide down along the marking frame 391, and the marks 392 in the marking frame 391 leave marks on the ground under the influence of the magnetic repulsion (here, leaving marks indicates the black grid of the two-dimensional code, and leaving no marks indicates the white grid of the two-dimensional code); when no current is passed through the coil, the electromagnet 393 loses its magnetism, and at this time, the permanent magnet and the iron block attract each other so that the marks 392 in the marking frame 391 remain on the top without leaving marks on the ground;

[0063] Among them, the reason why the positioning block 38 and the marking component 39 can be completed during the polishing and printing is that the controller 14 completes the lifting and lowering of the arrangement block 37 in the shell 31 by controlling the lifting and lowering of the lifting rod 32, so that the positioning block 38 and the marking component 39 arranged and fixed in the arrangement block 37 complete the contact with the ground, thereby completing the printing of the QR code on the ground.
