Description

Technical Field

[0001] The utility model relates to the technical field of grouting density detection, and particularly relates to a device for detecting the grouting density of assembled connections of precast components. Background Art

[0002] During the construction process of an assembled building structure, when grouting construction is carried out on precast components such as precast exterior walls through grouting sleeves, if the air in the grouting sleeve is not completely discharged, an air chamber will be formed in the grouting sleeve or the grouting cavity, resulting in grouting holes, so that the grouting density cannot meet the requirements, affecting the overall structural quality of the assembled building. Therefore, it is necessary to detect the density of the assembled grouting of precast components.

[0003] After retrieval, the utility model patent with the publication number of CN215180201U discloses a grouting density detection device, which includes a moving platform, a detection signal analyzer is arranged on the moving platform, a first sleeve is arranged on the moving platform, a second sleeve is arranged in the first sleeve, a first telescopic component is arranged between the second sleeve and the moving platform, a third sleeve is arranged at the other end of the second sleeve, a sliding rod is slidably connected in the third sleeve, a motor is arranged in the third sleeve, the sliding rod is connected with the motor through a gear component, the gear component includes a gear groove arranged at the upper end of the sliding rod and a gear arranged on the motor, a protection groove is arranged at one end of the sliding rod far away from the detection signal analyzer, a fixing plate is arranged in the protection groove, a detection probe is detachably arranged on the fixing plate, and the detection probe is signal-connected with the detection signal analyzer through a data transmission line.

[0004] However, the above patent still has the following deficiencies: The limitation of driving the detection probe to move up and down by the first telescopic component is relatively large. The first sleeve and the second sleeve themselves have a certain height, and the detection probe cannot be moved down to a certain height, which is not convenient for detecting the grouting density at low positions. In addition, when adjusting the lateral detection position of the detection probe, it is necessary to push the moving platform to achieve it, and the convenience is poor. For this reason, we propose a device for detecting the grouting density of assembled connections of precast components. Summary of the Utility Model

[0025] Embodiment:

[0026] Please refer to Figures 1-4 , a detection device for the grouting density of precast component assembly connection, including a moving table 1. A vertical frame 2 is fixedly connected to the top surface of the moving table 1. A first lead screw 3 is rotatably connected to the inner cavity of the vertical frame 2. A lifting seat 5 is threadedly sleeved on the outer side of the first lead screw 3. The end of the lifting seat 5 extends to the outside of the vertical frame 2 and is provided with a lateral moving mechanism 6. A lateral moving seat 7 is arranged on the lateral moving mechanism 6. A fitting mechanism 8 is arranged on the lateral moving seat 7. An ultrasonic density probe 9 is arranged on the fitting mechanism 8. A detection signal analyzer 11 is arranged on the top surface of the moving table 1. A signal transmission line 12 is fixedly connected between the detection signal analyzer 11 and the ultrasonic density probe 9. A first motor 4 is fixedly installed on the top surface of the vertical frame 2. The output shaft of the first motor 4 is connected to the top end of the first lead screw 3. Four self-locking casters 13 are fixedly installed on the bottom surface of the moving table 1.

[0027] Specifically, please refer to Figure 1 and Figure 2 , the lateral moving mechanism 6 includes a lateral moving box 14 fixedly connected to the end of the lifting seat 5. A second lead screw 15 is rotatably connected to the inner cavity of the lateral moving box 14. The second lead screw 15 is threadedly sleeved with the lateral moving seat 7. A second motor 16 is fixedly installed at the end of the lateral moving box 14. The output shaft of the second motor 16 is connected to the end of the second lead screw 15. The top surface and the bottom surface of the lateral moving seat 7 are respectively in contact with the inner wall of the lateral moving box 14.

[0028] In this embodiment, the inner wall of the transverse moving box 14 is used to limit the transverse moving seat 7, so that the transverse moving seat 7 can only move along the axial direction of the second lead screw 15.

[0029] Specifically, please refer to Figure 3 , the fitting mechanism 8 includes a mounting groove 17 opened at the end of the transverse moving seat 7. An electric push rod 18 is fixedly installed in the inner cavity of the mounting groove 17. The output end of the electric push rod 18 is fixedly connected with a mounting plate 19. The ultrasonic density probe 9 is fixedly installed on the end face of the mounting plate 19, and the side face of the mounting plate 19 is in contact with the inner wall of the mounting groove 17.

[0030] In this embodiment, the electric push rod 18 is used to drive the ultrasonic density probe 9 to move towards the grouting surface, ensuring that the ultrasonic density probe 9 is in contact with the outer side of the grouting area.

[0031] Specifically, please refer to Figure 3 and Figure 4 , a plurality of support columns 20 are fixedly connected to the end face of the mounting plate 19. The ends of the plurality of support columns 20 are rotatably connected with rolling balls 21, and the end faces of the rolling balls 21 are flush with the end face of the ultrasonic density probe 9.

[0032] In this embodiment, the support columns 20 and the rolling balls 21 are used to prevent the end of the ultrasonic density probe 9 from hitting the outer side of the precast member grouting area and causing damage. In addition, the rotation of the rolling balls 21 can assist the ultrasonic density probe 9 to move outside the grouting surface.

[0033] Specifically, please refer to Figure 1 , two limit rods 10 are fixedly sleeved in the inner cavity of the vertical frame 2, and the limit rods 10 are movably sleeved with the lifting seat 5.

[0034] In this embodiment, the lifting seat 5 is limited by the movable sleeve between the limit rod 10 and the lifting seat 5, so that the lifting seat 5 can only move along the axial direction of the first lead screw 3. In addition, the cooperation between the limit rod 10 and the lifting seat 5 enhances the strength of the lifting seat 5 in the inner cavity of the vertical frame 2.

[0035] Specifically, please refer to Figure 1 , handles 22 are respectively fixedly installed on both sides of the detection signal analyzer 11.

[0036] In this embodiment, the handle 22 is held to push the device, and at the same time, the self-locking casters 13 are used to drive the device to move.

[0037] Working principle: When in use, first hold the handle 22 with hand to move the device to the outside of the wall to be detected. At this time, use the self-locking function of the self-locking casters 13 to fix the device. Then start the electric push rod 18 to drive the mounting plate 19 and the ultrasonic density probe 9 to approach the wall, so that the detection end of the ultrasonic density probe 9 contacts the wall. At the same time, the rolling ball 21 contacts the outside of the wall. Start the ultrasonic density probe 9 to emit ultrasonic signals to the grouting part of the precast member, and use the ultrasonic density probe 9 to receive the reflected signals. Input the reflected signals into the detection signal analyzer 11 through the signal transmission line 12. Use the detection signal analyzer 11 to store and process the data collected at the grouting part, and generate a detection report. Then start the first motor 4 to drive the first lead screw 3 to rotate. Drive the lifting seat 5, the transverse moving mechanism 6 and the ultrasonic density probe 9 to move up and down through the threaded fit between the first lead screw 3 and the lifting seat 5, so as to adjust the height of the density detection. Finally, start the second motor 16 to drive the second lead screw 15 to rotate. Drive the transverse moving seat 7 and the ultrasonic density probe 9 to move horizontally through the threaded fit between the second lead screw 15 and the transverse moving seat 7, so that the ultrasonic density probe 9 moves horizontally outside the wall, so as to adjust the horizontal position of the density detection, and that's all.
