Description

Technical Field

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

[0002] Construction measurement is a crucial link in construction projects. It runs through the entire construction process and provides accurate spatial positioning and geometric dimension control for the smooth implementation of the project. In construction, ground flatness is an important indicator to measure construction quality, which directly affects subsequent decoration, equipment installation and usage functions. The measurement results provide a baseline for the decoration of walls, floors and ceilings to ensure the flatness and verticality of the decoration.

[0003] The existing construction measurement devices have the following problems:

[0004] When existing construction measurement devices use rollers to quickly screen large areas of smooth ground, the friction coefficient of the ground surface is low, which makes it easy for the roller to slip against the ground, affecting the accuracy of the measurement results. In addition, small particles and debris on the ground can easily interfere with the movement trajectory of the roller, which in turn causes deviations in the measurement results, thereby affecting the measurement efficiency of the measurement device for the flatness of the ground. Therefore, it cannot meet the existing use requirements of construction measurement devices. Summary of the Invention

[0005] In response to the above situation, in order to overcome the defects of the existing technology, this solution provides a construction measurement device that can increase the friction between the roller and the smooth ground, reduce the chance of the roller slipping during measurement, and remove impurities on the roller's movement trajectory, thereby ensuring the accuracy of ground flatness measurement.

[0006] The technical solution adopted in this scheme is as follows: A construction measurement device proposed in this scheme includes a detection and pushing frame, a measuring cylinder, a coarse detection type difference measuring mechanism and a heavy pressure type debris reduction mechanism. Multiple groups of measuring cylinders are arranged through the inner wall of the detection and pushing frame, the coarse detection type difference measuring mechanism is arranged on the measuring cylinder, and the heavy pressure type debris reduction mechanism is arranged on the coarse detection type difference measuring mechanism. The coarse detection type difference measuring mechanism includes a guide assembly, a pressure surface assembly and a distance measuring assembly. The guide assembly is arranged on the inner wall of the measuring cylinder, the pressure surface assembly is arranged at the end of the guide assembly away from the measuring cylinder, the distance measuring assembly is arranged on the guide assembly, and the heavy pressure type debris reduction mechanism includes an air supply assembly, a filtration assembly and an anti-slip assembly. The air supply assembly is arranged on the upper wall of the guide assembly, the filtration assembly is arranged on the upper wall of the air supply assembly, and the anti-slip assembly is arranged on the side wall of the pressure surface assembly.

[0007] As a further preference of this case, the guide assembly includes four corner blocks, a guide cylinder, a guide column and a guide spring, the four corner blocks are arranged in the middle position of the inner wall of the measuring cylinder, the guide cylinder is connected to the bottom wall of the measuring cylinder, the guide column is slidably arranged inside the guide cylinder, and the guide spring is arranged between the four corner blocks and the guide column; the pressure surface assembly includes a fixed wheel frame, a fixed wheel groove, a connecting cylinder and a roller cylinder, the fixed wheel frame is arranged on the bottom wall of the guide column, the fixed wheel groove is arranged on the bottom wall of the fixed wheel frame, the fixed wheel groove is opened on three sides, the connecting cylinder is symmetrically arranged on the inner walls at both ends of the fixed wheel groove, the roller cylinder is rotatably arranged between the connecting cylinders, and the connecting cylinder is connected to the roller cylinder; the ranging assembly includes a groove and a ranging sensor, the groove is arranged on the bottom wall of the four corner blocks, the groove is open at the lower end, and the ranging sensor is arranged in the groove of the bottom wall of the four corner blocks and is located above the guide column.

[0008] During use, the operator pushes the inspection and pushing frame, and the inspection and pushing frame drives the roller drum to roll to the ground to be measured through the measuring drum. The distance measuring sensor detects the initial distance between it and the guide column through the distance measuring end. The roller drum rolls on the ground to be measured. When the roller drum encounters an uneven road surface, the guide column uses the deformation of the guide spring to slide up and down along the guide drum. The distance measuring sensor detects and records the changing distance data between it and the guide column through the distance measuring end.

[0009] Preferably, the air supply assembly includes an air supply cylinder, an air supply pipe, an air delivery channel and a telescopic tube, the air supply cylinder is arranged on the upper wall of the four corner blocks, the air supply pipe passes through the four corner blocks and is connected to the side wall of the air supply cylinder, the air delivery channel is arranged inside the guide column, the telescopic tube passes through the guide column and is connected between the air supply pipe and the air delivery channel; the suction filter assembly includes a filter screen and an air pump, the filter screen is arranged on the upper wall of the measuring cylinder, the air pump is arranged on the upper wall of the air supply cylinder, and the exhaust end of the air pump is connected to the inside of the air supply cylinder through a pipe; the anti-slip assembly includes an anti-slip groove, a semicircular rubber cylinder, a debris removal port, a debris removal pipe and a counterweight block, multiple groups of the anti-slip grooves are arranged on the side wall of the roller cylinder, the anti-slip grooves are through-set, the semicircular rubber cylinder is arranged on the inner wall of the anti-slip groove, the debris removal port is arranged on the side of the semicircular rubber cylinder away from the roller cylinder, the debris removal pipe passes through the guide column and the fixed wheel frame and is connected between the connecting cylinder and the air delivery channel, and the counterweight blocks are symmetrically arranged on the upper wall of the fixed wheel frame.

[0010] When in use, when the roller drum is measuring the flatness of the ground with low friction coefficient such as ceramic tile, marble, epoxy floor, etc., the roller drum is easy to slide rather than roll, and the semi-circular rubber drum is normally in a concave state. At this time, the vacuum pump draws outside air through the vacuum end, and the outside air enters the air supply cylinder after being filtered by the filter. The air supply cylinder transports the air to the inside of the telescopic tube through the air supply pipe. The telescopic tube uses the air transmission channel to transport the air through the impurity removal pipe to the inside of the connecting cylinder. The connecting cylinder discharges the air into the inside of the roller drum. Due to the small aperture of the impurity removal port, the exhaust speed of the impurity removal port is lower than the speed of the air entering the roller drum from the impurity removal pipe. The semi-circular rubber cylinder is shaped like a ball. The roller drum changes direction and bulges outwards, and when rolling, it drives the semicircular rubber drum to contact the relatively smooth ground, thereby increasing the friction between the roller drum and the ground and reducing the chance of the roller drum sliding. When the bulged semicircular rubber drum contacts the ground, the counterweight block applies additional gravity to the roller drum, and the semicircular rubber drum is pressed back into the anti-skid groove, thereby ensuring the stability of the roller drum during rolling and avoiding errors in the distance measurement of the guide column by the distance sensor. The gas discharged from the impurity removal port can remove impurities on the roller drum's travel path, thereby preventing small particles and debris on the ground from interfering with the roller drum's movement trajectory and ensuring the accuracy of the measurement results.

[0011] Specifically, a controller is provided on the side wall of the inspection and pushing frame.

[0012] Wherein, the controller is electrically connected to the distance measuring sensor and the air pump respectively.

[0013] The beneficial effects achieved by adopting the above structure are as follows:

[0014] Compared with the existing technology, this scheme adopts a combination of a ball rolling structure and an inflatable anti-skid structure. Through the rough detection type difference measurement mechanism and the heavy pressure type impurity reduction mechanism, the guide assembly, the pressure surface assembly, the distance measurement assembly, the air supply assembly, the filtration assembly and the anti-skid assembly cooperate with each other to enable the roller drum to perform rolling measurement on relatively smooth floors such as ceramic tiles, marble, epoxy floors, etc. The gravity of the counterweight block is used to make the semicircular rubber cylinder protruding from the anti-skid groove retract into the anti-skid groove when it contacts the ground, thereby preventing the bulging semicircular rubber cylinder from causing the guide spring to deform and affect the distance measurement result of the distance measurement sensor on the guide column, thereby ensuring the accuracy of the roller drum's measurement of the flatness of the ground, and the gas discharged through the impurity removal port can remove particulate impurities on the rolling path of the roller drum, ensuring that the final measurement result will not deviate, thereby improving the roller drum's test efficiency for the flatness of the ground with a low surface friction coefficient to a certain extent.

[0035] The air supply assembly 18 includes an air supply cylinder 19, an air supply pipe 20, an air delivery channel 21 and a telescopic pipe 22. The air supply cylinder 19 is arranged on the upper wall of the four-corner block 5, the air supply pipe 20 passes through the four-corner block 5 and is connected to the side wall of the air supply cylinder 19, the air delivery channel 21 is arranged inside the guide column 7, and the telescopic pipe 22 passes through the guide column 7 and is connected between the air supply pipe 20 and the air delivery channel 21; the suction filter assembly 23 includes a filter screen 24 and an air pump 25, the filter screen 24 is arranged on the upper wall of the measuring cylinder 2, the air pump 25 is arranged on the upper wall of the air supply cylinder 19, and the exhaust end of the air pump 25 It is connected to the inside of the air supply cylinder 19 through a pipe; the anti-skid component 26 includes an anti-skid groove 27, a semicircular rubber cylinder 28, a debris removal port 29, a debris removal pipe 30 and a counterweight 31. Multiple groups of the anti-skid grooves 27 are arranged on the side wall of the roller cylinder 13, and the anti-skid grooves 27 are through-set. The semicircular rubber cylinder 28 is arranged on the inner wall of the anti-skid groove 27, and the debris removal port 29 is arranged on the side of the semicircular rubber cylinder 28 away from the roller cylinder 13. The debris removal pipe 30 passes through the guide column 7 and the fixed wheel frame 10 and is connected between the connecting cylinder 12 and the air supply channel 21. The counterweight 31 is symmetrically arranged on the upper wall of the fixed wheel frame 10.

[0036] A controller 32 is provided on the side wall of the detection and pushing frame 1 .

[0037] The controller 32 is electrically connected to the distance measuring sensor 16 and the air pump 25 respectively.

[0038] During specific use, the semicircular rubber cylinder 28 is normally in a recessed state, and the guide spring 8 is normally in an extended setting. The operator manually pushes the detection and pushing frame 1, which drives the roller cylinder 13 to roll to a large area of ​​the ground to be measured through the measuring cylinder 2. The controller 32 controls the distance sensor 16 to start, and the distance sensor 16 detects the initial distance between it and the guide column 7 through the distance measuring end;

[0039] When the roller drum 13 is measuring the flatness of a floor with a low coefficient of friction such as ceramic tile, marble, or epoxy floor, the roller drum 13 tends to slide rather than roll. At this time, the controller 32 controls the air extraction pump 25 to start, and the air extraction pump 25 draws outside air through the air extraction end. The outside air passes through the filter screen 24 and enters the air supply cylinder 19. The air supply cylinder 19 transports the air to the inside of the telescopic tube 22 through the air supply pipe 20. The telescopic tube 22 uses the air transmission channel 21 to transport the air to the inside of the connecting cylinder 12 through the impurity removal pipe 30. The connecting cylinder 12 discharges the air into the roller drum 13. Since the aperture of the impurity removal port 29 is small, the exhaust speed of the impurity removal port 29 is lower than the speed of the air entering the roller drum 13 from the impurity removal pipe 30. The semicircular rubber cylinder 28 deforms and bulges outwards. When the roller drum 13 rolls, it drives the semicircular rubber cylinder 28 to contact the relatively smooth ground, which can increase the friction between the roller drum 13 and the ground and reduce the probability of the roller drum 13 sliding.

[0040] The roller drum 13 rolls along the ground to be measured. When it encounters a ground with a height difference from the initial ground, the guide post 7 slides up and down along the guide drum 6 by virtue of the deformation of the guide spring 8. The distance between the distance measuring end of the distance measuring sensor 16 and the guide post 7 changes. The distance measuring sensor 16 detects and records the changed distance data between itself and the guide post 7 through the distance measuring end.

[0041] When the bulging semicircular rubber cylinder 28 comes into contact with the ground, the counterweight 31 applies additional gravity to the roller cylinder 13, and the semicircular rubber cylinder 28 is pressed back into the anti-skid groove 27, thereby ensuring the stability of the roller cylinder 13 during rolling and walking, avoiding the distance sensor 16 from misjudging the distance of the guide column 7, and the gas discharged from the impurity removal port 29 can remove impurities on the walking path of the roller cylinder 13, thereby avoiding small particles and debris on the ground interfering with the movement trajectory of the roller cylinder 13, ensuring the accuracy of the measurement results. The operator then compares the test data. When the height difference of the overall ground does not exceed the specified value, it indicates that the ground flatness meets the requirements; the above operation can be repeated the next time it is used.

[0042] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0043] The above description of the present solution and its implementation methods is non-limiting. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present solution, designs a similar structure and embodiment without creatively designing, they shall fall within the scope of protection of the present solution.
