[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. When testing the hardness of the shear wall, first fix the telescopic frame to the wall through the positioning mechanism. At this time, the adjustment component can elastically contact the wall. Then start the spray mechanism to clean and cool the wall to prevent the wall from affecting the measurement accuracy due to excessive temperature. At the same time, clean the wall;

[0034] 2. Start the rotating mechanism, which drives the rotating seat to rotate, and adjust the rotating seat to be relatively parallel to the wall, so that the test rod is perpendicular to the wall. The adjustment component can elastically abut against the wall, thereby increasing the connection stability between the support rod and the wall, and avoiding a small contact area between the end of the support rod and the wall due to poor wall flatness;

[0035] 3. Start the No. 3 telescopic rod to perform telescopic movement. The No. 3 telescopic rod drives the baffle to slide in the shell, so the air pressure in the outer groove cavity changes with the sliding of the baffle. Since all the test rods slide and are sealed with the end face of the shell, when the air pressure in the outer groove cavity changes, all the test rods simultaneously perform telescopic movement relative to the end face of the shell, so as to detect whether all the test rods can slide freely;

[0036] 4. Start the No. 2 telescopic rod, which drives the housing close to the wall. The housing drives all the test rods to contact and abut against the wall. Under the action of the hydraulic oil in the outer groove cavity, the abutment force between all the test rods and the wall is the same, thereby effectively measuring the hardness of each position of the wall.

[0037] 5. When the electric telescopic sleeve is extended or retracted, the electric telescopic sleeve drives the rotating seat to rotate through the pull rod, so that the rotating seat remains relatively parallel to the wall surface. When measuring the wall surface, all test rods can be perpendicular to the wall surface for wall surface quality testing, thus ensuring the accuracy of the wall surface quality test;

[0038] 6. By sliding the baffle back and forth in the shell, it is possible to detect whether all the test rods can be extended and retracted smoothly. While the test rods are extending and retracting, the wall dust on the surface of the test rods can be cleaned and filtered in the outer groove cavity through hydraulic oil, which improves the extension and retraction performance of all test rods and increases the accuracy of wall quality testing.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0049] like Figure 1-Figure 7 As shown, a construction shear wall quality testing device provided by the present invention comprises a telescopic frame 1, the telescopic frame 1 is connected with a positioning mechanism 2, the positioning mechanism 2 can be fixedly connected to a wall, the telescopic end of the telescopic frame 1 is fixedly connected with a cross bar 3, the cross bar 3 is rotatably connected with a rotating seat 4, and a rotating mechanism 5 for driving the cross bar 3 to rotate is arranged between the cross bar 3 and the rotating seat 4;

[0050] The rotating seat 4 is provided with a spray mechanism 6 for cleaning and cooling the wall surface. The rotating seat 4 is fixedly connected with a plurality of support rods 13. The ends of the support rods 13 are provided with adjustment components 7. The adjustment components 7 can elastically abut against the wall surface.

[0051] The end surface of the rotating seat 4 is fixedly connected with a No. 2 telescopic rod 10, and the telescopic end of the No. 2 telescopic rod 10 is fixedly connected with a shell 11. The end surface of the shell 11 is slidably penetrated and connected with a plurality of test rods 12. The test rods 12 are sealedly connected to the end surface of the shell 11. A baffle 17 is slidably and sealably connected in the shell 11. The shell 11 is fixedly connected with a No. 3 telescopic rod 16, and the telescopic end of the No. 3 telescopic rod 16 is fixedly connected to the baffle 17;

[0052] A sealed outer groove cavity 15 is provided between the baffle 17 and the inner end surface of the housing 11, and the outer groove cavity 15 is filled with hydraulic oil. A plurality of inner groove cavities 14 are provided in the outer groove cavity 15, and one end of each test rod 12 is inserted into an inner groove cavity 14. A flow guide component 8 is provided between the inner groove cavity 14 and the outer groove cavity 15. When the baffle 17 slides in the housing 11, the flow guide component 8 can filter impurities in the inner groove cavity 14 into the outer groove cavity 15; the outer groove cavity 15 is connected to a de-impurity mechanism 9, and the de-impurity mechanism 9 can filter and guide impurities in the outer groove cavity 15;

[0053] The control system controls the measurement accuracy of the shear wall quality by regulating the positioning mechanism 2, the rotating mechanism 5, the spraying mechanism 6, the impurity removal mechanism 9 and the third telescopic rod 16.

[0054] In this embodiment, when the hardness test is performed on the wall surface of the shear wall, the telescopic frame 1 is first fixed relatively to the wall surface by the positioning mechanism 2, and the adjustment component 7 can elastically contact the wall surface, and then the spray mechanism 6 is started to clean and cool the wall surface to prevent the wall surface from affecting the measurement accuracy due to excessive temperature, and at the same time clean the wall surface;

[0055] The rotating mechanism 5 is started, and the rotating mechanism 5 drives the rotating seat 4 to rotate, and the rotating seat 4 is adjusted to be relatively parallel to the wall surface, so that the test rod 12 is perpendicular to the wall surface, and the adjusting component 7 can elastically abut against the wall surface, and then the No. 3 telescopic rod 16 is started to perform telescopic movement, and the No. 3 telescopic rod 16 drives the baffle 17 to slide in the shell 11, so the air pressure in the outer groove cavity 15 changes with the sliding of the baffle 17. Since all the test rods 12 slide and are sealed with the end surface of the shell 11, when the air pressure in the outer groove cavity 15 changes, all the test rods 12 simultaneously perform telescopic movement relative to the end surface of the shell 11, so as to detect whether all the test rods 12 can slide freely;

[0056] Start the No. 2 telescopic rod 10, which drives the shell 11 to approach the wall. The shell 11 drives all the test rods 12 to contact and abut the wall. Under the action of the hydraulic oil in the outer groove cavity 15, the abutment force between all the test rods 12 and the wall is the same. Then, the concave marks at various positions of the wall are observed to detect the hardness of multiple positions of the wall.

[0057] like Figure 1 As shown, a construction shear wall quality testing device provided by the present invention, the positioning mechanism 2 includes a first telescopic rod 21, a positioning rod 22 and a connecting rod 23;

[0058] One end of the first telescopic rod 21 is slidably connected to the fixed part of the telescopic frame 1 , a connecting rod 23 is provided between the first telescopic rod 21 and the telescopic end of the telescopic frame 1 , and the other end of the first telescopic rod 21 is fixedly connected to a positioning rod 22 .

[0059] In this embodiment, the bottom of the telescopic frame 1 is abutted against the wall, and the positioning rod 22 is located on the other side of the wall. When the first telescopic rod 21 is retracted, the positioning rod 22 abuts against the wall.

[0060] When the telescopic end of the telescopic frame 1 is vertically extended and retracted, the telescopic end of the telescopic frame 1 drives the first telescopic rod 21 to move vertically synchronously through the connecting rod 23, thereby ensuring that the contact position between the positioning rod 22 and the wall always maintains the same distance with the wall quality test position, thereby ensuring the stability of the device during the test.

[0061] like Figure 3 As shown, a construction shear wall quality testing device provided by the present invention, the rotating mechanism 5 includes an electric telescopic sleeve 51 and a pull rod 52, the electric telescopic sleeve 51 is sleeved on the outside of the cross bar 3, and the fixed part of the electric telescopic sleeve 51 is fixedly connected to the telescopic end of the telescopic frame 1, and the pull rod 52 is rotatably connected between the telescopic end of the electric telescopic sleeve 51 and the rotating seat 4.

[0062] In this embodiment, when the electric telescopic sleeve 51 is extended and retracted, the electric telescopic sleeve 51 drives the rotating seat 4 to rotate through the pull rod 52, so that the rotating seat 4 remains relatively parallel to the wall surface, and then when measuring the wall surface, all the test rods 12 can be perpendicular to the wall surface to perform wall surface quality testing, thereby ensuring the accuracy of the wall surface quality testing.

[0063] like Figure 3 As shown, a construction shear wall quality testing device provided by the present invention, the spray mechanism 6 includes a spray pipe 61, a water tank 62, a first pump 63 and a telescopic water collecting plate 64;

[0064] The spray pipe 61 is fixedly connected to the top of the rotating seat 4, and an elastically retractable retractable water collecting plate 64 is provided at the bottom of the rotating seat 4. The rotating seat 4 is fixedly connected to a water tank 62 and a pump No. 1 63, and the pump No. 1 63 is connected between the water tank 62 and the spray pipe 61, and the water tank 62 is connected to the retractable water collecting plate 64, and a filter net 83 is provided between the water tank 62 and the retractable water collecting plate 64.

[0065] In this embodiment, pump No. 1 63 is started, and pump No. 1 63 drives the cooling water in the water tank 62 to be transmitted to the spray pipe 61. The spray pipe 61 sprays water to clean the wall and cools the wall at the same time. The telescopic water collecting plate 64 elastically abuts against the wall, and the cooling water flows from the wall into the telescopic water collecting plate 64. The cooling water in the telescopic water collecting plate 64 is filtered and re-enters the water tank 62 for recycling.

[0066] like Figure 3 As shown, a construction shear wall quality testing device provided by the present invention, the adjustment component 7 includes an air pump 71 and a rubber pad 72;

[0067] The ends of the support rods 13 are all provided with rubber pads 72 , the rotating seat 4 is fixedly connected with an air pump 71 , and all the rubber pads 72 are in communication with the air pump 71 .

[0068] In this embodiment, the air pump 71 is started to inflate all rubber pads 72 at the same time, thereby increasing the connection stability between the support rod 13 and the wall surface, and avoiding a small contact area between the end of the support rod 13 and the wall surface due to poor wall flatness.

[0069] like Figure 5 As shown, a construction shear wall quality testing device provided by the present invention is provided, wherein the flow guide assembly 8 includes a water outlet baffle 81, a water inlet baffle 82 and a filter screen 83;

[0070] Two through holes are provided on the end surface of the inner groove cavity 14. One through hole is located on the side surface inside the inner groove cavity 14 and is rotatably connected to a water outlet baffle 81 through an elastic torsion spring. The other through hole is located on the side surface outside the inner groove cavity 14 and is rotatably connected to a water inlet baffle 82 through an elastic torsion spring. The water outlet baffle 81 and the water inlet baffle 82 can close the two through holes under the elastic force of the elastic torsion spring. A filter screen 83 is provided on one side of the water outlet baffle 81.

[0071] In this embodiment, the third telescopic rod 16 is started to perform telescopic movement, and the third telescopic rod 16 drives the baffle 17 to slide in the shell 11, so the air pressure in the outer groove cavity 15 changes with the sliding of the baffle 17. Since all the test rods 12 slide and are sealed with the end surface of the shell 11, when the air pressure in the outer groove cavity 15 changes, all the test rods 12 perform telescopic movement relative to the end surface of the shell 11 at the same time;

[0072] During this process, when the baffle 17 slides to the right, the air pressure in the outer groove chamber 15 decreases, and all the test rods 12 shrink into the inner groove chamber 14. During this process, the wall dust attached to the side wall of the test rod 12 falls into the hydraulic oil in the inner groove chamber 14. The hydraulic oil in the inner groove chamber 14 flows out of the inner groove chamber 14 as the test rod 12 shrinks into the inner groove chamber 14. At this time, the water inlet baffle 82 is opened, and the hydraulic oil in the inner groove chamber 14 communicates with the wall dust impurities and enters the outer groove chamber 15.

[0073] Then the baffle 17 slides to the left, and under the push of the baffle 17, the water outlet baffle 81 opens, and the hydraulic oil in the outer groove chamber 15 flows back to all the inner groove chambers 14 through the filter screen 83, and all the test rods 12 are extended to the outside of the housing 11;

[0074] By the baffle 17 sliding back and forth in the shell 11, it is possible to detect whether all the test rods 12 can be smoothly extended and retracted. While the test rods 12 are extending and retracting, the wall dust on the surface of the test rods 12 can be cleaned by hydraulic oil and filtered in the outer groove cavity 15, thereby improving the extension and retraction performance of all the test rods 12 and increasing the accuracy of wall quality testing.

[0075] like Figure 5-Figure 6 As shown, a construction shear wall quality testing device provided by the present invention, the impurity removal mechanism 9 includes a filter box 91, an oil pump 92, an oil pipe 93 and a stop valve 94;

[0076] The housing 11 is connected to a filter box 91 , and two oil pumps 92 are connected between the filter box 91 and the outer tank cavity 15 . A stop valve 94 is provided on each of the oil pumps 92 . An oil pipe 93 is provided between the filter box 91 and one of the oil pumps 92 . A filter plate is provided in the filter box 91 .

[0077] In this embodiment, the oil pump 92 is started, and the oil pump 92 drives the hydraulic oil to circulate in the filter box 91 and the outer tank cavity 15. When the hydraulic oil passes through the filter box 91, the filter plate in the filter box 91 filters the impurities; when the stop valve 94 cuts off the oil pump 92, the outer tank cavity 15 remains sealed;

[0078] When all the test rods 12 press the wall, under the action of the hydraulic oil, all the test rods 12 can perform pressure testing on the wall with the same force, thereby effectively measuring the hardness of various positions of the wall.

[0079] like Figure 7 As shown, a construction shear wall quality testing device provided by the present invention, the control system includes:

[0080] A monitoring module, which includes a pressure monitoring unit, an angle monitoring unit, a temperature monitoring unit and a turbidity measurement unit;

[0081] The pressure monitoring unit is a pressure sensor, and the pressure sensor is arranged on the contact surface between the positioning rod 22 and the wall;

[0082] The angle monitoring unit is a tilt sensor, which is arranged at a position where the rotating seat 4 faces the wall, and is used to measure the relative tilt angle between the rotating seat 4 and the wall, thereby measuring the angle between the test rod 12 and the wall;

[0083] The temperature monitoring unit is a temperature sensor, and the temperature sensor is arranged at the position where the telescopic water collecting plate 64 contacts the wall surface;

[0084] The turbidity measuring unit is a turbidity sensor, and the turbidity sensor is arranged in the outer tank cavity 15;

[0085] A storage module, which is used to store the data information obtained by the monitoring module;

[0086] A processing module, which is used to retrieve the information of the limiting force between the positioning rod 22 and the wall, the angle between the test rod 12 and the wall, the temperature of the wall, and the turbidity of the hydraulic oil from the storage module, and form a control instruction after data analysis and judgment;

[0087] The control module receives the control instructions of the processing module and regulates the positioning mechanism 2 , the rotating mechanism 5 , the spraying mechanism 6 , the impurity removal mechanism 9 and the third telescopic rod 16 .

[0088] The processing module includes an evaluation unit and a judgment unit;

[0089] The evaluation unit monitors and acquires information on the limiting force between the positioning rod 22 and the wall, the angle between the test rod 12 and the wall, the temperature of the wall, and the turbidity of the hydraulic oil through the pressure monitoring unit, the angle monitoring unit, the temperature monitoring unit, and the turbidity measuring unit in the detection module, and forms pressure F, angle W, temperature T, and turbidity N, and transmits them to the evaluation unit for evaluation. The evaluation unit sets corresponding first preset thresholds corresponding to the pressure F, angle W, temperature T, and turbidity N. If at least one of them exceeds the corresponding first preset threshold, a control instruction is formed;

[0090] Furthermore, the judgment unit summarizes the obtained pressure F, angle W, temperature T and turbidity N to form detection condition information, constructs a data model and optimizes and trains it, and performs regression analysis on the obtained pressure F, angle W, temperature T and turbidity N through analysis software to obtain the influence of pressure F, angle W, temperature T and turbidity N on the measurement accuracy of wall hardness, and outputs the pressure influence factor Af, angle influence factor Aw, temperature influence factor At and turbidity influence factor An;

[0091] The judgment unit obtains pressure F, angle W, temperature T and turbidity N, and performs dimensionless processing on them, and associates them to form a control coefficient ZW. The association model is:

[0092]

[0093] Among them, F represents fixed pressure, 0.41≤Af≤0.61, W represents downward pressure angle, 0.12≤Aw≤0.63, T represents wall temperature, 0.21≤At≤0.71, N represents hydraulic oil turbidity, 0.11≤An≤0.19; Af represents pressure factor, Aw represents angle factor, At represents temperature factor, An represents turbidity factor, L represents hydraulic oil type influencing factor, among which mineral oil hydraulic oil takes value 1, synthetic hydraulic oil takes value 1.2, water-soluble hydraulic oil takes value 0.8;

[0094] The acquired detection condition coefficient ZW is transmitted to the judgment unit for comparison with a preset second preset threshold value, and if the detection condition coefficient ZW is not within the range of the second preset threshold value, a corresponding control instruction is generated;

[0095] When the control module receives the control instruction, it controls the positioning mechanism 2, the rotating mechanism 5, the spraying mechanism 6, the impurity removal mechanism 9 and the third telescopic rod 16 to achieve regulation of the fixed pressure, the downward pressure angle, the wall temperature and the turbidity of the hydraulic oil.
