[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] Please refer to Figure 1 - Figure 11 As shown in the figure, a template displacement monitoring device during concrete pouring includes a horizontal rod 1. The bottom end of the horizontal rod 1 is fixedly connected to a plumb bob 20 through a wire. The plumb bob 20 is inserted into the early warning base 21. The outer side of the plumb bob 20 does not contact the inner wall of the early warning base 21. The early warning base 21 is placed on the support plate 45. The rear end of the early warning base 21 is electrically connected to a storage battery 22 through a wire. The storage battery 22 is fixedly connected to the front end of a fixed shell 23. The bottom end of the fixed shell 23 is fixedly connected to a fixed bottom plate 24. Four groups of universal wheels 25 are fixedly connected to the bottom end of the fixed bottom plate 24. The top end of the storage battery 22 is electrically connected to an early warning light 26 through a wire. The other connection pin of the early warning light 26 is fixedly connected to the wire on the bottom end of the horizontal rod 1 through a wire. A lifting mechanism is arranged at the bottom end of the early warning light 26;

[0036] Through the structural design of the warning light 26, when the plumb bob 20 moves horizontally or downward and touches the warning base 21, the warning light 26 will flash and be accompanied by a warning bell, so as to give a warning in the first time to prompt the construction workers and enable them to handle it in time. When working, first fix the horizontal rod 1 at the bottom of the formwork to be monitored, and then connect the bottom end of the horizontal rod 1 and the top end of the plumb bob 20 together through a wire. The horizontal displacement and settlement warning values of the warning base 21 are both 10 mm. The rear end of the warning base 21 is connected to the storage battery 22 through a wire. The two wires fixed at the bottom end of the warning light 26 are respectively connected to the storage battery 22 and the wire on the horizontal rod 1. When the horizontal displacement or settlement of the horizontal rod 1 exceeds the warning value of the warning base 21, the horizontal rod 1 drives the plumb bob 20 to move, and the plumb bob 20 contacts the inner wall of the warning base 21. A complete circuit will be formed on the warning light 26, causing the warning light 26 to flash and emit a warning bell. At this time, the construction workers can stop the operation in time. The bottom end of the fixed base plate 24 is fixed with universal wheels 25 to facilitate the movement of the entire monitoring device, thereby improving the flexibility of the monitoring device and facilitating the monitoring device to be set at different monitoring points.

[0037] Furthermore, the lifting mechanism includes two groups of connecting columns 31. The top end of the connecting column 31 is fixedly connected to the bottom end of the warning light 26. The connecting column 31 passes through the mounting shell 27. The mounting shell 27 is fixedly connected to the top end of the fixed shell 23. The bottom end of the connecting column 31 is fixedly connected to the top end of the first moving block 30. A spiral line is provided on the inner wall of the first moving block 30. The first moving block 30 is slidably connected to the rotating rod 32. The top end of the rotating rod 32 is rotatably connected to the fixed shell 23 and the mounting shell 27. The bottom end of the rotating rod 32 is rotatably connected to the fixed base plate 24. A spiral line is provided on the rotating rod 32. A push block 29 is fixedly connected to the rear end of the first moving block 30. The bottom end of the push block 29 is fixedly connected to the air cylinder 28. The bottom end of the air cylinder 28 is fixedly connected to the fixed base plate 24. A fixing mechanism is provided at a position near the bottom end of the rotating rod 32;

[0038] Through the structural design of the lifting mechanism, the warning light 26 can be stored inside the mounting shell 27 when not in use, which is convenient for storing the warning light 26 and ensures that the warning light 26 is not easily damaged. At the same time, when the warning light 26 needs to be used, the warning light 26 can extend out from inside the mounting shell 27 to give warnings normally. During operation, the bottom end of the warning light 26 is connected to the first moving block 30 through two sets of connecting columns 31. When the air cylinder 28 pushes the first moving block 30 to move upward on the rotating rod 32, since spiral lines are provided on both the rotating rod 32 and the inner wall of the first moving block 30, when the first moving block 30 moves upward, the rotating rod 32 will rotate inside the fixed shell 23, and the warning light 26 will extend out from inside the mounting shell 27. A certain length of wire is reserved for the wire connected to the warning light 26 to ensure that the wire will not be pulled when the warning light 26 moves. The warning light 26 moves upward, facilitating the surrounding construction workers to timely see the warning of the warning light 26 and stop working immediately. Similarly, when the air cylinder 28 drives the first moving block 30 to move downward, the warning light 26 will gradually move downward until it is stored in the mounting shell 27. The mounting shell 27 provides protection for the periphery of the warning light 26 to reduce the interference of the external environment on the warning light 26 and prevent the warning light 26 from colliding with other objects.

[0039] Furthermore, the fixing mechanism includes a second moving block 33. The second moving block 33 is located directly below the first moving block 30. The inner wall of the second moving block 33 is provided with spiral lines with a reverse helix direction to that of the first moving block 30. The second moving block 33 is slidably connected to the rotating rod 32. The bottom end of the second moving block 33 is fixedly connected with four sets of support columns 38. The bottom ends of the support columns 38 are fixedly connected with rubber blocks 39. The bottom end of the rubber block 39 abuts against the ground. The support columns 38 penetrate through the fixed bottom plate 24. Through holes corresponding to the four sets of support columns 38 are provided on the fixed bottom plate 24. A protection mechanism is provided on the second moving block 33;

[0040] Through the structural design of the fixing mechanism, when the warning light 26 extends out of the installation shell 27 and works normally, the second moving block 33 will drive the four support columns 38 to move downward, so as to increase the friction force through the contact between the rubber block 39 and the ground, so as to fix the entire monitoring device and ensure that the monitoring device will not move easily during operation. During operation, the spiral line formed on the inner wall of the second moving block 33 is opposite to that of the first moving block 30. Therefore, when the first moving block 30 moves upward and drives the rotating rod 32 to rotate, the second moving block 33 will move downward and drive the four support columns 38 to move downward. Through holes corresponding to the support columns 38 are provided on the fixed bottom plate 24 to ensure the smooth movement of the support columns 38. When the second moving block 33 moves downward to the maximum position, the rubber block 39 fixed to the bottom end of the support column 38 will abut against the ground, so as to increase the friction force through the contact between the rubber block 39 and the ground. At this time, the monitoring device will not move easily, so that the monitoring device can maintain stability during operation.

[0041] Furthermore, the protection mechanism includes a connecting rod 34. The bottom end of the connecting rod 34 is rotatably connected to the left and right sides of the second moving block 33. The top end of the connecting rod 34 is rotatably connected to the bottom end of the pulling rod 35. The top end of the pulling rod 35 is rotatably connected to the bottom end of the rotating cover plate 36. The rotating cover plate 36 is rotatably connected to the installation shell 27. The rotating cover plate 36 is made of transparent PP material.

[0042] During operation, when the second moving block 33 moves downward, the second moving block 33 will pull the connecting rods 34 rotatably connected to the left and right sides downward. The connecting rod 34 is rotatably connected to the pulling rod 35, so it will pull the pulling rod 35 downward. The pulling rod 35 is rotatably connected to the bottom end of the rotating cover plate 36, so as to pull the rotating cover plate 36 to rotate and unfold the two rotating cover plates 36, facilitating the warning light 26 to extend out of the installation shell 27. Similarly, when the second moving block 33 moves upward, the warning light 26 will be received into the installation shell 27, and the two rotating cover plates 36 will rotate again until they contact each other, so as to close the upper part of the installation shell 27, thereby improving the protection effect of the installation shell 27 on the warning light 26. The rotating cover plate 36 is made of transparent PP material, so that even when the warning light 26 is received in the installation shell 27, the construction personnel can still observe the warning of the warning light 26 through the rotating cover plate 36.

[0043] Further, a first gear 40 is fixedly connected to a position of the rotating rod 32 near the bottom end. The first gear 40 meshes with a second gear 43. The second gear 43 is fixedly connected to a rotating shaft 42. The bottom end of the rotating shaft 42 is rotatably connected to the fixed bottom plate 24. A fixed block 44 is fixedly connected to the rotating shaft 42. The front end of the fixed block 44 is rotatably connected to a rotating block 48. A rotating groove corresponding to the rotating block 48 is formed at the front end of the fixed block 44. The rotating block 48 is fixedly connected to the rear end of the support plate 45. A notch 41 is formed in a group of support columns 38.

[0044] During operation, when the rotating rod 32 rotates, the first gear 40 fixed to its bottom end will drive the second gear 43 to rotate. The fixed block 44 will gradually rotate from the right side of the fixed shell 23 to the front of the fixed shell 23. So that when the monitoring device is not in use, the fixed block 44 and the support plate 45 can be stored, reducing the space occupied by the monitoring device. At the same time, the fixed block 44 and the support plate 45 are not easily damaged. A notch 41 is formed in one group of support columns 38 to prevent the rotation angle of the fixed block 44 from being restricted due to the abutment of the fixed block 44 and the support column 38.

[0045] Further, the rotating block 48 is designed in a T shape. A suspension ball 46 is fixedly connected to the bottom end of the support plate 45. The suspension ball 46 is located on the central axis of the support plate 45.

[0046] During operation, the support plate 45 is rotatably connected to the fixed block 44 through the rotating block 48. And there is a suspension ball 46 at the bottom end of the support plate 45. Under the action of the suspension ball 46, the support plate 45 will always be perpendicular to the ground, so that the warning base 21 can be kept horizontal with the ground. The suspension ball 46 is connected to the bottom end of the support plate 45 through a thin string.

[0047] Further, sleeve shells 37 are fixedly connected to both the left and right sides of the fixed shell 23. The inner wall of the sleeve shell 37 is in contact with the connecting rod 34.

[0048] During operation, the inner wall of the sleeve shell 37 is in contact with the connecting rod 34. So that when the connecting rod 34 moves, the connecting rod 34 can be guided to ensure that the connecting rod 34 can move stably along the vertical direction and prevent the connecting rod 34 from shaking greatly during movement.

[0049] Further, two counterweight grooves 50 are fixedly connected to a position of the fixed bottom plate 24 near the rear end. The two counterweight grooves 50 are symmetrically distributed along the central axis of the fixed bottom plate 24.

[0050] During operation, the counterweight grooves 50 are fixed to the fixed bottom plate 24. Heavy objects or other sundries can be placed in the counterweight grooves 50 for temporary storage. At the same time, the center of gravity of the monitoring device can be adjusted to solve the problem that the center of gravity of the monitoring device will shift forward due to the setting of the battery 22 in front of the fixed shell 23.

[0051] Embodiment 2

[0052] Please refer to Figure 3 and Figure 7 As shown, as another implementation mode of the present invention, a fixing plate 49 is fixedly connected to the fixing base plate 24. The cross-section of the fixing plate 49 is designed in an L shape, and the fixing plate 49 is located on the right side of the fixing shell 23;

[0053] During operation, the fixing plate 49 is fixed on the fixing base plate 24. When the fixing block 44 rotates from the front of the fixing shell 23 to the right side of the fixing shell 23, at this time, the fixing plate 49 can provide protection for the top ends of the fixing block 44 and the support plate 45.

[0054] A wire groove 47 is opened at the front end of the installation shell 27, and the wire groove 47 is designed in a U shape;

[0055] During operation, the opening of the wire groove 47 is to facilitate the wire connected to the warning light 26 to pass through the installation shell 27 smoothly, and the wire groove 47 also provides space for the movement of the wire on the warning light 26.
