Technical Field

[0001] The present invention relates to the technical field of prefabricated concrete production, in particular to a detection device for prefabricated concrete structures. Background Art

[0002] The inspection of prefabricated concrete structures is a key link in ensuring their quality and safety. Since prefabricated concrete structures have the advantages of higher batch production efficiency and more uniform structural stability compared to the more common integrated concrete structures, the production of prefabricated concrete structures is a construction method with great development prospects.

[0003] The stability of prefabricated concrete structures is particularly important, including the stability test of prefabricated concrete structures during installation. When installing prefabricated concrete, the prefabricated concrete structure needs to be placed at the installation site, and then the installation site is connected by pouring, so as to ensure the installation stability of the prefabricated concrete structure.

[0004] When conducting stability tests on prefabricated concrete structures, the pouring status cannot be clearly observed at the pouring mouth due to the accumulation of concrete during the installation process, making it impossible to know the internal pouring status. Therefore, a small hole is usually opened on the pouring template, and a sight glass is passed through the small hole to detect the pouring status. However, if splashing occurs between concrete or uneven accumulation of concrete causes impurities to adhere to the sight glass, the sight glass needs to be replaced or cleaned frequently, resulting in the inability to quickly obtain the test results. Summary of the Invention

[0005] The purpose of the present invention is to provide a detection device for assembled concrete structures.

[0012] A further technical improvement of the present invention is that a bevel spring is fixed on the rotating connecting rod, which is a tension spring, and the other end is fixed inside the supporting shell. The rotating connecting rod and the supporting shell are slidingly connected, and the end of the rotating connecting rod is provided with a bevel end.

[0013] The further technical improvement of the present invention is that: a side support base is fixed on the side of the supporting shell, a sliding groove is connected on the side support base and the supporting shell, a sliding plate is slidingly arranged inside the sliding groove, a connecting rod and a sliding rod are fixedly installed on the sliding plate respectively, the sliding rod and the side support base are slidably connected, and the sliding rod extends out of the side support base, a receiving plate is fixed at the end of the sliding rod, an extrusion spring is arranged between the sliding plate and the sliding groove, a bevel groove is fixed at the end of the connecting rod, and the bevel groove and the bevel end cooperate.

DETAILED DESCRIPTION

[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0026] See also Figure 1-4As shown, a detection device for prefabricated concrete structures includes a supporting shell 1, and a scope end 2 for detecting the prefabricated concrete structure is arranged inside the supporting shell 1, and the position of the scope end 2 is adjustable. When the scope end 2 is located inside the supporting shell 1, the supporting shell 1 is used to store the scope end 2 to protect the scope end 2. When the scope end 2 is removed from the supporting shell 1, the scope end 2 is used to monitor the internal pouring status of the prefabricated concrete.

[0027] As a further embodiment of the present application, a scope protection film 3 is provided inside the supporting shell 1, wherein the scope protection film 3 can be stably attached to the scope end 2 due to the electrostatic effect, and the scope protection film 3 is used to provide secondary protection to the scope end 2. During use, when the scope end 2 is removed from the inside of the supporting shell 1, the scope protection film 3 is attached to the scope end 2 to protect the scope end 2 again.

[0028] As a further embodiment of the present application, the mirror protective film 3 is replaceable, that is, a raw material winding assembly 4 and a waste material winding assembly 10 are provided inside the supporting shell 1, wherein the raw material winding assembly 4 is used to place the cleaning film 20, and the waste material winding assembly 10 is used to place the waste film 26. When in use, the raw material winding assembly 4 winds up the cleaning film 20, and the waste material winding assembly 10 is used to wind up the waste film 26. When the mirror end 2 is moved out from the inside of the supporting shell 1, the raw material winding assembly 4 and the waste material winding assembly 10 are started at the same time, and the waste material winding assembly 10 is used to wind up the waste film 26 and release the cleaning film 20 until the cleaning film 20 is located on the mirror end 2 and covers the mirror end 2, thereby realizing the replacement of the mirror protective film 3 on the mirror end 2. It can be quickly replaced each time it is used to ensure the cleanliness of the mirror end 2.

[0029] The raw material winding assembly 4 includes a rotating connecting rod 19, wherein a first winding roller 18 for winding the cleaning film 20 is rotatably provided on the rotating connecting rod 19, wherein the first winding roller 18 and the rotating connecting rod 19 have a damping force to ensure the stability of the first winding roller 18; and the waste winding assembly 10 includes a second winding roller 25, wherein the rotating rod of the second winding roller 25 is installed on another set of connecting rods, and there is a damping force between the connecting rod and the second winding roller 25 to ensure the stability of the second winding roller 25. In the present application, the functions of the first winding roller 18 and the second winding roller 25 can ensure that the peephole protective film 3 is always at a certain tightness.

[0030] In order to realize the relative rotation of the first winding roller 18 and the second winding roller 25, a first winding gear 17 is fixed to the side of the first winding roller 18, and a second winding gear 24 is fixed to the side of the second winding roller 25. At the same time, a pressure rod 8 is slidably provided on the support shell 1, and a meshing ring 5 for meshing the first winding gear 17 and the second winding gear 25 is evenly provided on the pressure rod 8. Therefore, when in use, when the pressure rod 8 moves longitudinally, it drives the meshing ring 5 to move downward, and at this time drives the first winding gear 17 and the second winding gear 25 rotate, and the mirror protective film 3 keeps the same winding direction on the first winding roller 18 and the second winding roller 25. At this time, the waste film 26 is wound on the second winding roller 25, and the waste side faces the second winding roller 25, which can avoid the problem of falling and sticking caused by the waste facing the mirror end 2 when it is wound, thereby further ensuring the cleanliness of the mirror end 2 and ensuring that the clean mirror protective film 3 can be used during detection, thereby ensuring the detection accuracy of the mirror end 2.

[0031] Furthermore, the pressure rod 8 is fixedly mounted on the top plate 6 , and a top plate 7 is fixed on the top of the supporting shell 1 , wherein the pressure rod 8 and the top plate 7 are slidably connected, so that the stability of the pressure rod 8 can be maintained during use.

[0032] In order to replace the endoscope protective film 3 each time the endoscope tip 2 is used, in the present application, when the first winding roller 18 and the second winding roller 25 are not in use, the first winding gear 17 and the second winding gear 24 are respectively disengaged from the meshing ring 5.

[0033] Specifically, a side support base 9 is fixed to the side of the support shell 1, wherein the side support base 9 and the support shell 1 are connected to each other with a sliding groove 11, wherein a sliding plate 16 is slidingly provided inside the sliding groove 11, and a connecting rod 12 and a sliding rod 14 are fixedly installed on the sliding plate 16, respectively. The sliding rod 14 is slidably connected to the side support base 9, and the sliding rod 14 extends out of the side support base 9, and a receiving plate 13 is fixed to the end of the sliding rod 14, wherein an extrusion spring 15 is provided between the sliding plate 16 and the sliding groove 11, and at the same time, a connecting rod 12 is fixed to the connecting rod 12. The end of the supporting shell 1 is fixed with an inclined groove 23, wherein a rotating connecting rod 19 is slidingly provided on the supporting shell 1, wherein the end of the rotating connecting rod 19 is provided with an inclined end 22, and the inclined end 22 is used to cooperate with the inclined groove 23. At the same time, an inclined spring 21 is fixed on the rotating connecting rod 19, and the inclined spring 21 is a tension spring, and the other end is fixed to the inside of the supporting shell 1. Therefore, when in use, when the supporting shell 1 contacts the surface of the assembled concrete, the receiving plate 13 contacts the surface of the concrete, and the receiving plate 13 applies pressure upward, and the sliding plate 16 Slide longitudinally inside the sliding groove 11, and the connecting rod 12 moves upward until the bevel groove 23 at the end of the connecting rod 12 moves to the highest end. At this time, the bevel groove 23 cooperates with the bevel end 22, so that the rotating connecting rod 19 overcomes the pulling force of the bevel spring 21, so that the first winding gear 17 and the second winding gear 24 move toward each other laterally and cooperate with the meshing ring 5 respectively. At this time, the longitudinal action of the pressure rod 8 will drive the rotation of the first winding gear 17 and the second winding gear 24, thereby realizing the replacement of the mirror protective film 3. After use, release the opposite side. The downward pressure of the side support base 9, under the pulling force of the extrusion spring 15, causes the receiving plate 13 to move away from the side support base 9. At this time, the connecting rod 12 moves downward, and the upper part of the inclined groove 23 cooperates with the inclined end 22. Under the action of the inclined spring 21, the first winding roller 18 and the second winding roller 24 are respectively released from the meshing ring 5. At this time, the used waste film 26 will be located on the support shell 1 and will be replaced when it is used next time. The extrusion spring 15 is a tension spring, one end of which is fixed on the sliding plate 16 and the other end is fixed inside the sliding groove 11.

[0034] When the present invention is in use, when the supporting shell 1 contacts the surface of the prefabricated concrete, the receiving plate 13 contacts the surface of the concrete, and the receiving plate 13 applies upward pressure. At this time, the sliding plate 16 slides longitudinally inside the sliding groove 11, and the connecting rod 12 moves upward until the bevel groove 23 at the end of the connecting rod 12 moves to the highest end. At this time, the bevel groove 23 cooperates with the bevel end 22, so that the rotating connecting rod 19 overcomes the tension of the bevel spring 21, so that the first winding gear 17 and the second winding gear 24 move toward each other laterally and cooperate with the meshing ring 5 respectively. At this time, the longitudinal action of the pressure rod 8 will drive the first winding gear 17 and the second winding gear The rotation of the wheel 24 realizes the replacement of the endoscope protective film 3. After use, the downward pressure on the side support base 9 is released. Under the pulling force of the extrusion spring 15, the receiving plate 13 moves away from the side support base 9. At this time, the connecting rod 12 moves downward, and the upper part of the inclined groove 23 cooperates with the inclined end 22. Under the action of the inclined spring 21, the first winding roller 18 and the second winding roller 24 are respectively released from the meshing ring 5. At this time, the used waste film 26 will be located on the support shell 1 and will be replaced when it is used next time. The extrusion spring 15 is a tension spring, one end of which is fixed on the sliding plate 16 and the other end is fixed inside the sliding groove 11.
