[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, living, learning, and public activities.

[0017] Another technical solution proposed by the present invention is to provide a detection method of a construction engineering quality detector, comprising the following steps:

[0018] S1: First, when testing, the first screw lifter is connected to an external motor to drive the output shaft of the first screw lifter to rotate, and the output shaft of the second screw lifter can be driven to rotate by cooperating with the central connecting rod, so that the first push rod and the second push rod push the installation frame upward to adjust the height, and the threaded rod is driven actively by starting the motor, so that the movable push block drives the scanner body to detect the wall;

[0019] S2: Then, when the movable push block moves to one end and drives the scanner body to perform detection, it can drive the fixed rack to move at the same time. Therefore, when the fixed rack moves, it can drive the rotating gear to rotate clockwise, and the rotating gear drives the first bevel gear to rotate through the rotating rod, and then drives the second bevel gear to rotate through the first bevel gear, and uses the second bevel gear to drive the active screw to rotate clockwise, so as to achieve the purpose of the connecting frame squeezing the first suction cup and the second suction cup, so that the first suction cup and the second suction cup are adsorbed on the wall. When the scanner body returns after the detection, it will drive the rotating gear to rotate counterclockwise through the fixed rack, and through the cooperation of the rotating rod, the first bevel gear and the second bevel gear, drive the active screw to rotate counterclockwise, so as to achieve the purpose of the connecting frame releasing the squeezing of the first suction cup and the second suction cup, so that it is convenient for the staff to cut off the adsorption of the first suction cup and the second suction cup on the wall;

[0020] S3: Then, when the scanner body detects the position of the steel bar through the steel bar detection module, an alarm will be issued through the alarm module after detection. At this time, the single chip trigger signal sending module sends a signal, and then the signal receiving module receives the signal. The signal analysis module triggers the execution module to stop the motor, and at the same time, the first electric push rod and the second electric push rod are started. The first electric push rod and the second electric push rod are used to drive the first mounting clamp and the second mounting clamp to move closer to the wall, thereby driving the marking ink strip to mark the wall;

[0021] S4: Finally, when the movable push block drives the scanner body to move, the slide bar will move at the same time driven by the scanner body. After the scanner body finishes measuring the steel bar spacing and marks the line, the staff can roughly estimate the distance through the indicator rod and the measuring ruler body. If it exceeds the qualified line by too much, the staff can directly understand the test result. If it is close to the qualified line, they can wait for the test result of the scanner body and the test is completed.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. A construction engineering quality detector and detection method, when inspecting a wall, bring the installation frame close to the wall, start the motor to drive the threaded rod actively, so that the movable push block drives the scanner body to inspect the wall, so as to solve the problem that the integrated steel bar scanner is manually pushed for measurement during use, and cannot maintain linear motion during pushing, resulting in large measurement error and low accuracy. The first screw lifter is connected to an external motor to drive the output shaft of the first screw lifter to rotate, and the output shaft of the second screw lifter can be driven to rotate through cooperation with the center connecting rod, so that the first push rod and the second push rod push the installation frame upward, so as to achieve the purpose of changing the measurement height, and can measure different heights of the same wall, and can detect whether the internal steel bars are bent, thereby ensuring the quality of the inspection.

[0024] 2. A construction project quality detector and detection method, the scanner body detects the position of the steel bar through the steel bar detection module, and after detection, an alarm will be issued through the alarm module. At this time, the single-chip microcomputer triggers the signal sending module to send a signal, and then the signal receiving module receives the signal. The signal analysis module triggers the execution module to stop the motor, and at the same time, the first electric push rod and the second electric push rod are started. The first electric push rod and the second electric push rod are used to drive the first mounting clamp and the second mounting clamp to move closer to the wall, thereby driving the marking ink stick to mark the wall, which is convenient for marking after measurement.

[0025] 3. A construction engineering quality detector and detection method. When the movable push block drives the scanner body to move, the mounting plate will move through the slide bar driven by the scanner body, and the slide bar will drive the indicator rod, the mounting plate, the storage outer rod and the telescopic inner rod to move. At this time, the power of the scanner body during movement will drive the mounting plate to pull the indicator rod into a bent state. After the scanner body stops moving, the reset spring will drive the bent indicator rod to return to its original position, so that the marking plate fits the wall surface and leaves a mark. After the scanner body finishes measuring the steel bar spacing and draws the line mark, the staff can roughly visually estimate the distance through the indicator rod and the measuring ruler body. If it exceeds the qualified line by too much, the detection result can be directly understood without waiting for the scanner body to give the result. The detection speed is fast, and the line mark can be compared with the mark left by the marking plate, thereby improving the work efficiency of the staff.

[0026] 4. A construction engineering quality detector and detection method, when the installation frame is close to the wall before detection, the first suction cup and the second suction cup are driven to overlap the wall, and the active screw is rotated. The active screw drives the first driven screw and the second driven screw to rotate through the organic cooperation of the active wheel, the first driven wheel and the second driven wheel, so that the active pressure block drives the first driven pressure block and the second driven pressure block to move to one end at the same time through the fixed connecting rod, and drives the connecting frame to squeeze the first suction cup and the second suction cup, and discharge the internal air of the first suction cup and the second suction cup, so that they are adsorbed on the wall, and the reaction force of the supporting spring can drive the first suction cup and the second suction cup to be further close to the wall, which solves the problem that the manual hand-held method has poor stability, which easily leads to further increase in the error of the measurement result. When the movable push block moves to one end, the first and second driven pressure blocks are driven to move to one end. When the scanner body is moving for detection, it can drive the fixed rack to move at the same time. Therefore, when the fixed rack moves, it can drive the rotating gear to rotate clockwise, and the rotating gear drives the first bevel gear to rotate through the rotating rod, and then drives the second bevel gear to rotate through the first bevel gear. The second bevel gear drives the active screw to rotate clockwise, so as to achieve the purpose of the connecting frame squeezing the first suction cup and the second suction cup, so that the first suction cup and the second suction cup are adsorbed on the wall. When the scanner body returns after the detection, it will drive the rotating gear to rotate counterclockwise through the fixed rack, and through the cooperation of the rotating rod, the first bevel gear and the second bevel gear, drive the active screw to rotate counterclockwise, so as to achieve the purpose of the connecting frame releasing the squeezing of the first suction cup and the second suction cup, so that the staff can cut off the adsorption of the first suction cup and the second suction cup on the wall, and improve the convenience of suction cup adsorption.

[0043] Specifically, when inspecting the wall, the installation frame 3 is brought close to the wall, and the threaded rod 72 is driven actively by starting the motor 71, so that the movable push block 73 drives the scanner body 1 to detect the wall, so as to solve the problem that the integrated steel bar scanner is manually pushed for measurement during use, and cannot maintain linear motion during pushing, resulting in large measurement error and low accuracy.

[0054] Specifically, when the installation frame 3 is close to the wall before detection, the first suction cup 102 and the second suction cup 103 are driven to overlap the wall, and the active screw 104 is rotated. The active screw 104 drives the first driven screw 105 and the second driven screw 106 to rotate through the organic cooperation of the active wheel 1011, the first driven wheel 1012 and the second driven wheel 1013, so that the active pressure block 107 drives the first driven pressure block 108 and the second driven pressure block 109 to move to one end at the same time through the fixed connecting rod 1010, and drives the connecting frame 101 to squeeze the first suction cup 102 and the second suction cup 103, and discharge the internal air of the first suction cup 102 and the second suction cup 103, so that they are adsorbed on the wall, and the reaction force of the support spring 1015 can drive the first suction cup 102 and the second suction cup 103 to be further close to the wall, thereby solving the problem that the manual hand-held method has poor stability and is prone to further increase the error of the measurement result.

[0057] Specifically, when the movable push block 73 moves to one end and drives the scanner body 1 to perform detection, the fixed rack 113 can be driven to move at the same time. Therefore, when the fixed rack 113 moves, the rotating gear 112 can be driven to rotate clockwise. The rotating gear 112 drives the first bevel gear 114 to rotate through the rotating rod 111, and then drives the second bevel gear 115 to rotate through the first bevel gear 114.

[0058] Another technical solution proposed by the present invention is to provide a detection method of a construction engineering quality detector, comprising the following steps:

[0059] Step 1: First, when testing, the first screw lift 61 is connected to an external motor to drive the output shaft of the first screw lift 61 to rotate, and the output shaft of the second screw lift 62 can be driven to rotate by cooperating with the central connecting rod 63, so that the first push rod 64 and the second push rod 65 push the mounting frame 3 upward to adjust the height, and the threaded rod 72 is driven actively by starting the motor 71, so that the movable push block 73 drives the scanner body 1 to detect the wall;

[0060] Step 2: Then, when the movable push block 73 moves to one end and drives the scanner body 1 to perform detection, the fixed rack 113 can be driven to move at the same time. Therefore, when the fixed rack 113 moves, the rotating gear 112 can be driven to rotate clockwise. The rotating gear 112 drives the first bevel gear 114 to rotate through the rotating rod 111, and then drives the second bevel gear 115 to rotate through the first bevel gear 114. The second bevel gear 115 drives the active screw 104 to rotate clockwise, so that the connecting frame 101 squeezes the first suction cup 102 and the second suction cup 102. The purpose of the second suction cup 103 is to make the first suction cup 102 and the second suction cup 103 adsorb on the wall. When the scanner body 1 returns after the detection, the fixed rack 113 drives the rotating gear 112 to rotate counterclockwise, and the active screw 104 is driven to rotate counterclockwise through the cooperation of the rotating rod 111, the first bevel gear 114 and the second bevel gear 115, so as to achieve the purpose of releasing the squeezing of the first suction cup 102 and the second suction cup 103 by the connecting frame 101, so as to facilitate the staff to cut off the adsorption of the first suction cup 102 and the second suction cup 103 on the wall;

[0061] Step 3: Next, when the scanner body 1 detects the position of the steel bar through the steel bar detection module 21, an alarm will be issued through the alarm module 22 after detection. At this time, the single chip computer 23 triggers the signal issuing module 24 to send a signal, and then the signal receiving module 25 receives the signal, and the signal analysis module 26 triggers the execution module 27 to stop the motor 71, and at the same time, the first electric push rod 91 and the second electric push rod 92 are started, and the first electric push rod 91 and the second electric push rod 92 are used to drive the first mounting clamp 93 and the second mounting clamp 94 to move closer to the wall, thereby driving the marking ink strip 95 to mark the wall;

[0062] Step 4: Finally, when the movable push block 73 drives the scanner body 1 to move, the slide bar 82 will move simultaneously driven by the scanner body 1. After the scanner body 1 completes the measurement of the steel bar spacing and draws the line mark, the staff can roughly estimate the distance through the indicator rod 83 and the measuring ruler body 81. If it exceeds the qualified line by too much, the staff can directly understand the test result. If it is close to the qualified line, they can wait for the test result of the scanner body 1 and the test is completed.

Therefore, when the fixed rack (113) moves, the rotating gear (112) can be driven to rotate clockwise.

When the scanner body (1) returns after detection, the fixed rack (113) drives the rotating gear (112) to rotate counterclockwise. Through the cooperation of the rotating rod (111), the first bevel gear (114) and the second bevel gear (115), the active screw (104) is driven to rotate counterclockwise, so that the connection frame (101) releases the squeezing of the first suction cup (102) and the second suction cup (103), which facilitates the staff to cut off the adsorption of the first suction cup (102) and the second suction cup (103) on the wall.

The signal analysis module (26) triggers the execution module (27) to stop the motor (71), and at the same time, the first electric push rod (91) and the second electric push rod (92) are started. The first electric push rod (91) and the second electric push rod (92) are used to drive the first mounting clamp (93) and the second mounting clamp (94) to move closer to the wall, thereby driving the marking ink strip (95) to mark the wall; S4: Finally, when the movable push block (73) drives the scanner body (1) to move, the slide bar (82) will move simultaneously under the drive of the scanner body (1). After the scanner body (1) has finished measuring the steel bar spacing and marked the line, the staff can roughly visually estimate the distance through the indicator rod (83) and the measuring ruler body (81). If it exceeds the qualified line by too much, the staff can directly understand the test result. If it is close to the qualified line, the staff can wait for the test result of the scanner body (1) and the test is completed.
