Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering detection, and in particular to an intelligent detection device for assembled construction engineering. Background Art

[0002] Prefabricated thermal insulation exterior wall panels are a very common building component in prefabricated construction projects. They have the advantages of energy saving and environmental protection, high construction efficiency, controllable quality, reduced on-site construction difficulty and strong adaptability. However, prefabricated thermal insulation exterior wall panels are spliced ​​piece by piece during the construction of prefabricated construction projects. Although the joints between two prefabricated thermal insulation exterior wall panels are sealed with sealant, the sealant may not be completely sealed or the sealing performance may be poor, resulting in the following defects: 1. Hot and cold air will be exchanged through the joints, resulting in increased heat loss and reduced thermal insulation performance of the building; 2. Poorly sealed joints can easily allow rainwater, moisture, etc. to penetrate into the interior of the building, which may cause dampness and mold in the wall over a long period of time, and even cause corrosion of the internal prefabricated metal components, affecting the quality; 3. Poor sealing at the joints will affect the sound insulation effect of the building, and external noise can be transmitted into the room through these gaps, affecting the comfort of use. Therefore, it is necessary to test the sealing performance of the joints during the construction of prefabricated thermal insulation exterior wall panels in prefabricated construction projects.

[0003] However, the following problems exist in the process of testing the sealing performance of the joints of prefabricated thermal insulation exterior wall panels: the existing testing device usually fits the open end of the square tube with the wall panel to form a closed space between the square tube and the wall panel, and the joints of the prefabricated thermal insulation exterior wall panels are located in the square tube, and then a certain pressure of air is filled into the square tube, and then the pressure value change of the pressure gauge is observed to determine whether the sealing performance of the joints of the prefabricated thermal insulation exterior wall panels is qualified. However, the heights of the prefabricated thermal insulation exterior wall panels used in different positions during the construction process are different. The existing testing device only tests prefabricated thermal insulation exterior wall panels of one height. Therefore, multiple devices or the size of the square tube need to be changed during the test to test the joints of prefabricated thermal insulation exterior wall panels of different sizes, thereby affecting the efficiency of the test. Secondly, the existing testing method only achieves the fitting of the square tube and the wall panel by pushing, and this method has poor fitting degree and is easy to affect the test results.

[0029] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] As Figure 1 shown, an intelligent detection device for prefabricated building engineering includes a fixing plate 1; a detection mechanism 2 is provided on the fixing plate 1.

[0031] As Figure 1 , Figure 2 and Figure 3 shown, the detection mechanism 2 includes a telescopic cylinder 20. The telescopic cylinder 20 is fixedly installed at the right end of the fixing plate 1. The telescopic section of the telescopic cylinder 20 slidably penetrates through the fixing plate 1 and is fixedly installed with a pressing plate 21. The pressing plate 21 has a U-shaped structure. Four limit columns arranged in a rectangle are fixedly installed at the left end of the fixing plate 1. The left ends of the limit columns slidably penetrate through the pressing plate 21 and are jointly fixedly installed with a support plate 22, and the support plate 22 is slidably installed left and right in the pressing plate 21.

[0032] As Figure 1 and Figure 2 shown, an adjusting part 23 for adjusting the detection range is provided on the support plate 22. Adsorbing parts 24 are provided on both the support plate 22 and the adjusting part 23. A sealing part 25 is provided between the support plate 22 and the adjusting part 23.

[0033] During specific operation, the fixing plate 1 is fixedly installed on an external moving device. Then, the external moving device moves the intelligent detection device for prefabricated building engineering to the position where detection is required. Then, the adjusting part 23 extends to the required detection length. Then, the detection mechanism 2 is attached to the wall panel. The adsorption part 24 is used to ensure the degree of adhesion between the detection mechanism 2 and the wall panel. Then, the telescopic cylinder 20 is used to further improve the degree of adhesion between the detection mechanism 2 and the wall panel. At the same time, the sealing part 25 ensures the sealing performance at the movable part of the adjusting part 23, thereby ensuring the accuracy of detection. After that, a certain pressure of gas is filled into the detection mechanism 2, and then the numerical change of the external pressure gauge connected to the support plate 22 is observed to determine whether the sealing performance of the joint of the prefabricated thermal insulation exterior wall panel is qualified.

[0034] As Figure 1 , Figure 2 and Figure 3As shown, the adjusting part 23 includes a sliding plate 230. Two vertically symmetric sliding plates 230 are slidably mounted up and down at the left end of the vertical section of the support plate 22. The left ends of the two sliding plates 230 are fixedly mounted with U-shaped plates 231. The openings of the two U-shaped plates 231 face each other. A pressurizing component, a support member 3 for supporting the sliding of the sliding plate 230, and a pushing and pulling member 4 for driving the two U-shaped plates 231 to move are provided on the support plate 22.

[0035] As Figure 2 and Figure 3 shown, the support member 3 includes a support plate 30. The support plate 30 is fixedly mounted at the left end of the vertical section of the support plate 22 and between the two U-shaped plates 231. Circular grooves are formed at one ends of the two vertical sections of the U-shaped plate 231 close to the support plate 30. Support columns 31 are slidably mounted up and down in the circular grooves. One ends of the support columns 31 away from the corresponding U-shaped plates 231 are fixedly connected to the support plate 30.

[0036] As Figure 2 and Figure 3 shown, the pushing and pulling member 4 includes a double-acting electric push rod 40. The double-acting electric push rod 40 is fixedly mounted at the rear end of the horizontal section at the rear of the support plate 22. Both telescopic sections of the double-acting electric push rod 40 are fixedly connected to the corresponding U-shaped plates 231 through connecting blocks 41.

[0037] As Figure 2 、 Figure 3 and Figure 5 shown, the pressurizing component includes a charging pipe 232. The charging pipe 232 communicating with its interior is fixedly mounted at the front end of the horizontal section at the front of the support plate 22.

[0038] As Figure 2 、 Figure 3 and Figure 4 shown, the adsorption part 24 includes mounting holes. A plurality of mounting holes are formed at the left end of the U-shaped plate 231 and the left ends of the two horizontal sections of the support plate 22. Rubber pads 240 are mounted at the left end of the U-shaped plate 231 and the left ends of the two horizontal sections of the support plate 22. The mounting holes penetrate through the corresponding rubber pads 240. Suction cups 241 are communicated in the mounting holes. Control components for controlling the suction and release of the corresponding suction cups 241 are provided on both the support plate 22 and the U-shaped plate 231.

[0039] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the control component includes a first pipeline. The mounting holes located on the horizontal section of the same support plate 22 are connected through the first pipeline, and the mounting holes on the same U-shaped plate 231 are connected through a second pipeline. First air inlet pipes 242 communicating with the corresponding first pipelines are fixedly installed at the opposite ends of the two horizontal sections of the support plate 22, and a second air inlet pipe 243 communicating with the corresponding second pipeline is fixedly installed at the front end of the vertical section on the front side of the U-shaped plate 231.

[0040] During specific operation, the bidirectional electric push rod 40 pushes the two U-shaped plates 231 away from each other through the connecting block 41. The U-shaped plates 231 move through the support and guidance of the support columns 31 to extend the detection range of the detection mechanism 2. After the U-shaped plates 231 move to the required positions, the bidirectional electric push rod 40 stops pushing and keeps the current extended amount unchanged. Then, the telescopic cylinder 20 pushes the pressing plate 21 towards the wall panel. The pressing plate 21 will first push the rubber pad 240 to contact the wall panel through the sealing part 25. Then, an external air pump is connected to the first air inlet pipe 242 and the second air inlet pipe 243 through a delivery pipe. The suction cups 241 are connected to each other through the corresponding first pipeline and second pipeline. Then, the adsorption of the wall panel by the suction cups 241 will drive the rubber pad 240 to closely adhere to the wall panel to improve the fitting degree between the U-shaped plates 231, the support plate 22 and the wall panel. Then, as the telescopic cylinder 20 continues to push the pressing plate 21 towards the wall panel, the telescopic cylinder 20 will drive the sealing part 25 through the pressing plate 21 to seal the moving parts between the U-shaped plates 231, the sliding plate 230 and the support plate 22. At the same time, the sealing part 25 and the pressing plate 21 are used to push and squeeze the U-shaped plates 231, the sliding plate 230 and the support plate 22 to further improve the fitting degree between the rubber pad 240 and the wall panel, thereby improving the sealing performance of the closed space formed by the U-shaped plates 231, the sliding plate 230, the support plate 22 and the wall panel during the detection process, and further ensuring the accuracy of the sealing performance detection of the precast thermal insulation panel joints.

[0041] Then, the external air pump is connected to the inflation pipe 232 through an external pipeline to fill a certain pressure of gas into the closed space formed by the U-shaped plates 231, the sliding plate 230, the support plate 22 and the wall panel. Then, observe the numerical change of the external pressure gauge connected to the support plate 22 to judge whether the sealing performance of the precast thermal insulation exterior wall panel joints is qualified.

[0042] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, the sealing portion 25 includes a sealing gasket 250, and the sealing gaskets 250 are installed along the inner contour of the support plate 22 near the edge of the U-shaped plate 231 at the upper and lower ends of the support plate 22, and the upper and lower ends of the two horizontal sections of the support plate 22 are both installed with a No. 1 pushing plate 251 for sliding forward and backward, and the upper and lower ends of the vertical section of the support plate 22 are both installed with a No. 2 pushing plate 252 for sliding left and right, a linkage part 5 is arranged between the No. 2 pushing plate 252 and the No. 1 pushing plate 251, and an actuator 6 for driving the No. 2 pushing plate 252 to move is arranged on the pressure plate 21.

[0043] like Figure 1 , Figure 5 and Figure 6 As shown, the linkage member 5 includes a driving plate 50, and the opposite ends of the two No. 2 pushing plates 252 are fixedly installed with the driving plates 50. The driving plates 50 are provided with inclined grooves 51 at positions corresponding to the No. 1 pushing plates 251 one by one. The inclined grooves 51 are inclined from the left to the middle of the fixed plate 1, and the No. 1 pushing plate 251 is fixedly installed with guide columns 52 that slide through the corresponding inclined grooves 51.

[0044] like Figure 1 , Figure 5 and Figure 6 As shown, the actuator 6 includes a groove, and a groove is opened at a position where the left end of the vertical section of the pressure plate 21 corresponds to the limit column. A compression spring 60 mounted on the corresponding limit column is fixedly installed in the groove, and the left end of the compression spring 60 is fixedly connected to the right end of the support plate 22. A connecting plate 61 is fixedly installed between the upper and lower ends of the pressure plate 21 and the corresponding No. 2 pushing plate 252.

[0045] During operation, after the suction cup 241 is adsorbed on the wall panel, the support plate 22 and the profile plate 231 are attached to the wall panel through the corresponding rubber pad 240 and cannot move further. Then, as the telescopic cylinder 20 continues to push the pressing plate 21 to move toward the wall panel, the pressing plate 21 will compress the compression spring 60 and move toward the support plate 22. The movement of the pressing plate 21 will push the second pushing plate 252 through the connecting plate 61 to push the sealing pad 250 to fit tightly against the right end of the slide plate 230, and the movement of the second pushing plate 252 will be through the guide column 52 The cooperation with the inclined groove 51 drives the two No. 1 pushing plates 251 to approach each other, and the two No. 1 pushing plates 251 will push the sealing gasket 250 to fit tightly with the C-shaped plate 231 and the slide plate 230, and the No. 1 pushing plate 251 will contact with the No. 2 pushing plate 252, so as to seal the movable part between the C-shaped plate 231, the slide plate 230 and the support plate 22. At this time, the pressure plate 21 also contacts with the support plate 22 to further improve the fit between the rubber pad 240 and the wall panel, thereby ensuring the accuracy of the detection result.
