[0001] The utility model relates to a wall inclination monitoring and warning device, belonging to the field of building construction equipment. Background Art

[0002] At present, in prefabricated buildings, prefabricated walls produced in factories are usually transported to construction sites for assembly. This allows some prefabricated walls to be factory-produced, greatly improving the efficiency of construction operations.

[0003] When the prefabricated wall is assembled on site, it is lifted to the floor slab by lifting equipment and steel cables. After the reserved steel bar holes at the bottom of the prefabricated wall are aligned and connected with the embedded steel bars on the floor slab, the prefabricated wall can be fixed. During the prefabricated wall fixing operation, it is necessary to ensure that the wall surface is perpendicular to the floor slab, that is, to ensure that the wall surface remains in a vertical state. Therefore, the inclination state of the wall surface must be monitored by external monitoring instruments.

[0004] The existing method of monitoring the inclination of prefabricated walls is to manually operate a square ruler or a laser level to perform monitoring operations, which not only has certain limitations in the operating environment, but also has low monitoring accuracy.

[0005] Therefore, we propose a wall tilt monitoring and warning device to solve the above technical problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example:

[0021] See also Figure 1 to Figure 2 A wall tilt monitoring and warning device comprises a base 1. The bottom of the base 1 is provided with supporting feet, which can facilitate the vertical placement of the device.

[0022] A support rod 2 is fixedly connected to the top of the base 1. Specifically, the support rod 2 is a telescopic support rod, including a fixed section 21 and an extension section 22 that are movably sleeved and installed. The outer wall of the fixed section 21 is screwed with a telescopic rod bolt 23 for positioning the extension section 22. By loosening and tightening the telescopic rod bolt 23, the extension section 22 can be pulled up and down to adjust the height of the support rod 2, thereby changing the height position of the device detection instrument body.

[0023] A U-shaped bracket 3 is fixedly connected to the top of the support rod 2, and a detector assembly 4 is arranged on the inner side of the U-shaped bracket 3. The left and right side walls of the detector assembly 4 are rotatably installed with the U-shaped bracket 3 by setting a pin shaft 5. The center of gravity of the detector assembly 4 is located directly below the pin shaft 5. The detector assembly 4 is installed by rotation. The purpose is that when the base 1 of the device is placed on a non-horizontal surface, the center of gravity of the detector assembly 4 changes. At this time, the detector assembly 4 can be rotated by the pin shaft 5 to reset its center of gravity to directly below the pin shaft 5, thereby ensuring that the detector assembly 4 always remains upright; the detector assembly 4 has a first laser ranging sensor 41 and a second laser ranging sensor 42 that are spaced apart and distributed in parallel in an upper and lower manner; that is, the first laser ranging sensor 41 and the second laser ranging sensor 42 are ensured to be on the same vertical line.

[0024] The detector assembly 4 includes a detector body 43 and a detector extension body 44. A lifting rod 45 is connected to the bottom of the detector extension body 44. The lifting rod 45 can be inserted into the detector body 43 in a damped and movable manner. The first laser ranging sensor 41 and the second laser ranging sensor 42 are respectively arranged on the detector body 43 and the detector extension body 44. The purpose is to adjust the distance between the first laser ranging sensor 41 and the second laser ranging sensor 42. When working, the distance between the first laser ranging sensor 41 and the second laser ranging sensor 42 is enlarged to reduce the monitoring error. When idle, the distance between the first laser ranging sensor 41 and the second laser ranging sensor 42 is pulled down for easy storage.

[0025] A center of gravity adjustment component is provided on the back of the detector body 43, and the center of gravity adjustment component includes a vertically fixed slide rail 46, on which a counterweight slider 47 is slidably installed, and a counterweight bolt 48 for positioning the counterweight slider 47 is threaded on the counterweight slider 47. The center of gravity change of the detector component 4 can be adjusted by loosening or tightening the counterweight bolt 48 and sliding the counterweight slider 47 up and down. When the distance between the first laser ranging sensor 41 and the second laser ranging sensor 42 is adjusted, the overall center of gravity of the detector component 4 changes accordingly. At this time, the center of gravity adjustment component can be used to compensate and adjust the center of gravity of the detector component 4 to return to directly below the pin shaft 5.

[0026] In order to facilitate whether the center of gravity is restored to be directly below the pin shaft 5 when adjusting the center of gravity, a level bubble gauge 49 is provided on the top of the detector body 43. When the detector body 43 is horizontal, it means that it is restored to be directly below the pin shaft 5.

[0027] The monitoring and warning device also includes a comparison and analysis processor 6, and the first laser ranging sensor 41 and the second laser ranging sensor 42 are communicatively connected to the comparison and analysis processor 6; the first laser ranging sensor 41 and the second laser ranging sensor 42 have the same structure, both include a laser emitting unit and a receiving unit, and the distance is calculated by calculating the time from laser emission to reflection reception, and the first laser ranging sensor 41 and the second laser ranging sensor 42 can convert the monitoring signal into an electrical signal, so as to facilitate sending it to the comparison and analysis processor 6. The comparison and analysis processor 6 only needs to have a simple data comparison function. When working, the distance data measured by the first laser ranging sensor 41 and the second laser ranging sensor 42 are calculated by the comparison and analysis processor 6, and the difference is calculated; and a warning threshold is set in the system control program. When the distance difference measured by the first laser ranging sensor 41 and the second laser ranging sensor 42 is greater than the warning threshold, a warning signal is generated.

[0028] In order to facilitate the presentation of monitoring results and the issuance of warning signals, the device also includes a handheld device 7, which is equipped with a placement seat 73. The placement seat 73 is fixedly arranged on the support rod 2 and can be taken and used at any time, which is convenient for taking and placing. The handheld device 7 is provided with a display screen 71 and a buzzer 72. The display screen 71 and the buzzer 72 in the handheld device 7 can be connected to the comparison and analysis processor 6 by wired or wireless communication. The monitoring results can be viewed in real time through the display screen 71, and the staff can be notified in time through the buzzer 72 when the comparison and analysis processor 6 generates a warning signal.

[0029] The working principle of this utility model:

[0030] The device is placed upright on the floor b. According to the size of the prefabricated wall a to be installed, the support rod 2 is adjusted to determine the height position of the device monitoring body. The height of the detector extension body 44 is adjusted to determine the distance between the first laser ranging sensor 41 and the second laser ranging sensor 42. Then, the detector body 43 is adjusted to a horizontal upright state by adjusting the center of gravity adjustment component. The device is powered on. The first laser ranging sensor 41 and the second laser ranging sensor 42 monitor the distance between the two and the wall. Then, the comparison and analysis processor 6 compares and calculates the distance data measured by the first laser ranging sensor 41 and the second laser ranging sensor 42 to calculate the difference. A warning threshold is set in the system control program. When the difference in the distance measured by the first laser ranging sensor 41 and the second laser ranging sensor 42 is greater than the warning threshold, a warning signal is generated. The monitoring results can be viewed in real time through the display screen 71. When the comparison and analysis processor 6 generates a warning signal, the staff can be notified in time through the buzzer 72.
