Description

Technical Field

[0001] The invention relates to the technical field of concrete reinforcement detection, in particular to a concrete reinforcement detector for engineering quality management. Background Art

[0002] After the completion of the construction project, in order to achieve final acceptance and ensure the completeness of the construction progress and the quality of the construction, the appearance of the building after completion and the steel bar structure and distribution inside the concrete wall will be inspected. For example, the use of a steel bar scanner can be used to detect the distribution of steel bars inside the concrete walls and building floor slabs to determine whether they meet the construction requirements of the building drawings and whether they meet the maximum load-bearing requirements, thereby reducing safety issues such as low overall strength of the building due to cutting corners after the completion of the building.

[0003] Existing steel bar detectors generally include steel bar scanners, steel bar corrosion detectors, anchor rod pullers, and steel bar position measuring instruments, among which steel bar scanners are generally used for quality inspection of building completion acceptance and building management. Through components such as photoelectric sensors, optical instruments are used to detect steel bars and conduct fixed-point construction, which is convenient for inspection personnel to use and detect the distribution of steel bars inside concrete. During the inspection process, display equipment can also be used to intuitively view the distribution of steel bars inside concrete, thereby improving the accuracy and convenience of engineering quality management applications.

[0004] When the rebar scanner is scanning and fixing the rebar, its fixing operation can generally achieve precise positioning. However, if it is used in a concrete building under construction, due to the complex construction site environment and the dust emission and pollution caused by the construction process, the scanner will mark the vertices of the rebar. The marks will be affected by the dust adsorbed on the walls or floors, and the fixing marks will not be clear. At the same time, during the fixing process, dust will also be collected into the scanner through the heat dissipation holes, affecting its internal electrical balance and the rebar detection operation.

[0005] In view of the above problems, it is urgently necessary to carry out innovative design based on the original concrete steel bar detector. Summary of the invention

[0016] Preferably, the nozzle is located directly below the air guide pipe through-connecting ports on the left and right sides of the buoyancy chamber, wherein the bottom of the buoyancy chamber where the weighting cylinder is located is concave.

[0017] Preferably, an electrically controlled valve is also installed at the connection between the air guide tube and the buoyancy chamber on the side away from the gas pressurization component, wherein the one-way valve is located below the pressure pump, and the one-way valve is used for one-way conduction from the buoyancy chamber to the inside of the weighting cylinder.

[0038] 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.

[0039] See also Figure 1-Figure 9 The present invention provides a technical solution: a concrete steel bar detector for engineering quality management, comprising:

[0040] A mobile platform 1, the top of which is hinged with one end of a telescopic bracket 2, and a steel bar scanner 3 and a display component 4 are respectively embedded and installed on the front and rear sides of the mobile platform 1, and a photoelectric detection unit 5 is detachably installed above the display component 4, and an electric screw assembly 6 is also installed at the rear edge of the mobile platform 1, and a fixed-point sprayer 7 is connected to the electric screw assembly 6; universal wheels are also installed at the four corners of the bottom of the mobile platform 1, and a scanning port of the steel bar scanner 3 is set through the bottom of the mobile platform 1, and the steel bar scanner 3 is connected to the display component 4 for communication;

[0041] In this technical solution, if Figure 1-Figure 5 and Figure 8 As shown, first, the mobile platform 1 is pushed by the telescopic bracket 2 hinged thereon, and the mobile platform 1 can be placed on the bottom or top of the concrete cast wall or floor slab to be inspected for engineering quality through the universal wheel structure at the bottom thereof, and the position of the mobile platform 1 is moved by the telescopic bracket 2. When the photoelectric detection unit 5 is disassembled, the display image of the steel bar scan can be viewed intuitively through the steel bar scanner 3 and the display component 4. When fixed-point marking of steel bar detection is required, the movement of the electric screw assembly 6 and the fixed-point sprayer 7 can be controlled under the steel bar detection scan through the installation of the photoelectric detection unit 5 and the integrated circuit composed of the photoelectric detection unit 5, and the fixed-point marking under the steel bar detection is performed on the inspected building through the fixed-point sprayer 7, which is convenient for subsequent viewing.

[0042] In the above technical solution, if Figure 8 and Fig. 9 As shown, the elastic injection capsule 8 is embedded in the middle of the telescopic bracket 2, and a pipeline is connected between the elastic injection capsule 8 and the fixed-point sprayer 7; the fixed-point sprayer 7 is threadedly connected with the electric screw assembly 6, the fixed-point sprayer 7 and the moving platform 1 form a sliding installation structure that engages, and a screw pump is arranged at the inner center of the fixed-point sprayer 7; the bottom discharge port of the fixed-point sprayer 7 is distributed in a "Y" shape, the material of the fixed-point sprayer 7 is set to elastic rubber, and an elastic pleated belt is arranged at the "Y"-shaped gap of the fixed-point sprayer 7, and the elastic pleated belt is used to gather the fixed-point sprayer 7;

[0043] The mixed color solution is continuously added to the fixed-point sprayer 7 through the elastic injection bag 8, and the fixed-point marking is performed through the fixed-point sprayer 7. In this process, the movement of the fixed-point sprayer 7 and the start-up of the screw pump inside it are automatically controlled by the stepping motor and the integrated circuit on the electric screw assembly 6. When the screw pump is started, the mixed color solution is pressurized. The liquid pressurization causes the elastic pleated belt at the bottom of the fixed-point sprayer 7 to expand, and the mixed color solution is sprayed out for fixed-point marking. When the screw pump stops working, the bottom of the fixed-point sprayer 7 is closed, which effectively prevents the leakage of the mixed color solution.

[0044] This technical solution also includes Figure 1 and Figure 6-Figure 7Contents shown: At the same time, a gas pressurizing component 9 is fixed in the middle of the telescopic bracket 2, one end of an air guide tube 10 is connected to the gas pressurizing component 9, and the other end of the air guide tube 10 is also connected to the outer shell of the mobile platform 1, and an exhaust hole 11 is opened at the bottom of the mobile platform 1; the air guide tube 10 also penetrates into the elastic liquid injection bag 8, and the elastic liquid injection bag 8 is provided with a dust filter component for the gas inside the air guide tube 10;

[0045] The use of the above technical solution continuously realizes the pressurized diversion and discharge of gas through the gas pressurizing component 9 and the air duct 10. The diverted gas is filtered for dust through the dust filter component, and the filtered clean gas is discharged through the air duct 10, so that the gas can not only dissipate heat and cool the inside of the mobile platform 1, but also remove impurities such as dust accumulated at the building to be tested, thereby improving the subsequent steel bar detection efficiency and the accuracy and durability of fixed-point marking.

[0046] In the above technical solution, the air pipe 10 is configured as a telescopic threaded hose, wherein the air pipe 10 is connected to the inside of the dust filter assembly, and the dust filter assembly is suspended inside the elastic liquid injection bag 8; so that when the mobile platform 1 is pushed downward or upward due to the inclination of the telescopic bracket 2, the dust filter assembly can float to a position above the liquid level inside the elastic liquid injection bag 8, which is convenient for dust filtering operations using the mixed color solution inside the elastic liquid injection bag 8.

[0048] By using the weighting cylinder 1002, when the buoyancy chamber 1001 is suspended to the liquid level inside the elastic liquid injection bag 8, the weighting cylinder 1002 is located below the liquid surface, which makes it easy to use the pressure pump 1004 to pressurize the mixed color solution inside the elastic liquid injection bag 8, so that the mixed color solution is discharged from the nozzle 1003, and an atomization area is formed inside the buoyancy chamber 1001. The atomization area is just located on the gas flow path brought by the air guide tube 10, thereby realizing the clean operation of the gas guided by the air guide tube 10 and filtering the dust in the gas.

[0049] Furthermore, in the present technical solution, an electrically controlled valve is also installed at the connection between the air guide tube 10 and the buoyancy chamber 1001 on the side away from the gas pressurization component 9, wherein the one-way valve 1005 is located below the pressure pump 1004, and the one-way valve 1005 is used for one-way conduction from the buoyancy chamber 1001 to the inside of the weighting cylinder 1002; when dust impurities remain in the buoyancy chamber 1001, the gas is introduced into the buoyancy chamber 1001 by closing the electrically controlled valve and continuously pressurizing the gas pressurization component 9, and the dust mixed solution remaining in the buoyancy chamber 1001 can be introduced into the elastic injection bag 8 through the one-way valve 1005, and the subsequent dust impurity mixed solution is discharged through a special fixed-point sprayer 7.

[0050] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment further provides a filter chamber 12 structure, wherein the air guide tube 10 between the elastic liquid injection capsule 8 and the mobile platform 1 is arranged in a "Y" shape, wherein the air guide tube 10 is hidden inside the telescopic bracket 2, and a filter chamber 12 is provided at the "Y"-shaped transition point of the air guide tube 10; the filter chamber 12 and the telescopic bracket 2 are fixedly mounted by bolts, and a water vapor drying filter assembly is provided in the filter chamber 12 to filter the water vapor in the gas circulating inside the air guide tube 10;

[0051] The filter chamber 12 is detachable to facilitate the replacement of the filter layer for drying water vapor inside it, so that the gas introduced into the steel bar detector by the air guide tube 10 is clean and dry, and will not bring in dust and water vapor to cause damage to the internal electrical components of the steel bar detector.
