Therefore, it cannot be construed as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0022] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0023] The present invention provides a bracket displacement monitoring device. Refer to Figure 1 - Figure 2 , which includes: a steel sleeve 100 sleeved outside the bracket vertical rod 10. An airbag is provided inside the steel sleeve 100, and a plurality of airbags are distributed circumferentially along the bracket vertical rod 10; an inflation device 200 for inflating the airbag to make the airbag expand radially and contact the bracket vertical rod 10; a detection device 300 communicated with the airbag for monitoring the pressure change of the airbag to detect the offset of the bracket vertical rod 10.

[0024] By providing an airbag in the steel sleeve 100, the airbag contacts the bracket vertical rod 10. When the bracket vertical rod 10 is offset, the airbag is squeezed, and the detection device 300 monitors the pressure change of the airbag, so that the displacement of the bracket vertical rod 10 can be detected, automatic monitoring can be realized, the monitoring data can be displayed in real time, and automatic early warning can be performed, saving labor and having accurate observation.

[0025] In one embodiment, refer to Figure 1 - Figure 4, the detection device 300 includes a hose 310, a pressure detection mechanism 320, a sub-data processing module 330, a total data processor 340, an alarm device 350, and a display 360; airbags are provided at both the top and bottom of the steel casing 100; two airbags that are centrosymmetric about the center of the bracket vertical rod 10 are respectively connected to the two pressure detection mechanisms 320 through the hose 310, and the sub-data processing module 330 receives the data of the pressure detection mechanism 320 through the input line 370; multiple groups of airbags correspond to multiple sub-data processors and are finally summarized to the total data processing module; the total data processing module is connected to the alarm device 350 and the display 360 through the output line 380. The pressure detection mechanism 320 includes a U-shaped tube 321, a high-precision infrared rangefinder 322, a floating block 323, and a ranging liquid 324. The ranging liquid 324 is located at the bottom of the U-shaped tube 321. The air inlet end of the U-shaped tube 321 is connected to the hose 310. The floating block 323 is located on the ranging liquid 324 on one side of the air outlet end of the U-shaped tube 321. The high-precision infrared rangefinder 322 is installed at the top of the air outlet end of the U-shaped tube 321.

[0026] The inflating device 200 can be automatically inflated. After the inflating device 200 fills the airbag with gas, the tube cavity above the liquid level at the air inlet of the U-shaped tube 321 is filled with gas. As the gas increases, the airbag support vertical rod 10 grows radially in the direction, the length of the airbag is D, and the diameter is r. The inflating device 200 stops inflating until it contacts the support vertical rod 10. When the support vertical rod 10 moves, the vertical rod will squeeze multiple airbags. During the squeezing process, only the length changes while the diameter r remains unchanged, and the length decreases by d. The squeezed gas is transmitted to the U-shaped tube 321 through the hose 310. During the transmission process, the diameters of the hose 310 and the U-shaped tube 321 remain unchanged, and the diameters of the hose 310, the U-shaped tube 321, and the airbag are the same when they are filled with gas. After squeezing, the gas in the airbag enters the U-shaped tube 321 and pushes the liquid level of the ranging liquid 324 in the U-shaped tube 321 to drop. The reduced height is d, and the liquid level at the other end rises by d. A floating block with a negligible thickness is arranged on the liquid level at the other end. A high-precision infrared ranging instrument 322 is arranged at the top of the air outlet end of the U-shaped tube 321. Before the support vertical rod 10 is displaced, the high-precision infrared ranging instrument 322 measures the distance between it and the liquid level as t. The high-precision infrared ranging instrument 322 continuously measures the distance between it and the liquid level. When the support vertical rod 10 is displaced, at this time, there is squeezing between the upper and lower airbags in the same direction. The squeezed gas of the upper and lower airbags enters the U-shaped tube 321 through the hose 310 respectively, causing the liquid level to change. The airbag corresponding to the high-precision infrared ranging instrument 322 at the top of the steel sleeve 100 measures the distance between it and the liquid level as t1, and the airbag corresponding to the high-precision infrared ranging instrument 322 at the bottom of the steel sleeve 100 in the same direction measures the distance between it and the liquid level as t2. The high-precision infrared ranging instrument 322 is connected to the sub-data processing module 330 through the input line 370. The sub-data processing module 330 stores and calculates the distance measured by the high-precision infrared ranging instrument 322 due to the squeezing change of the upper and lower airbags in the same vertical direction. MAX(t - t2) - (t - t1) is the verticality in the same vertical direction, and MAX(t - t2) - (t - t1) is the horizontal displacement in the same vertical direction. The sub-data processing module 330 transmits the processed data to the total data processor 340 through the input line 370 for storage and calculation. MAX[MAX(t - t2) - (t - t1)] corresponding to all the data of the sub-data processing module 330 is the verticality, and MAX[MAX(t - t2) - (t - t1)] is the horizontal displacement. The total data processor 340 transmits the signals of the verticality and the horizontal displacement to the display 360 through the output line 380 for real-time display. When the data processed by the total data processor 340 reaches the warning values of the verticality and the horizontal displacement, it is transmitted to the alarm device 350 through the output line 380 for alarm.

[0027] In one embodiment, refer to Figure 1 - Figure 4, a fixing device 120 is provided outside the steel casing 100 for supporting the steel casing 100 outside the bracket vertical rod 10. The fixing device 120 includes side ears 121 and telescopic legs 122. A plurality of side ears 121 are welded to the side of the steel casing 100, and the telescopic legs 122 are connected through the side ears 121. The bottom end of the telescopic legs 122 is fixed on the ground. The telescopic legs 122 include: a first leg 123 and a second leg 124. One end of the second leg 124 is slidably connected to the inside of one end of the first leg 123. An adjusting screw 125 is provided at the top end of the second leg 124. The adjusting screw 125 is helically connected with a driven gear 126. A driving gear 127 is rotatably connected to one side of the first leg 123. The driven gear 126 meshes with the driving gear 127, and a rocker 128 is installed on the driving gear 127. The first leg 123 is connected to the side ear 121 through a pin 129, and the rotation angle between the first leg 123 and the side ear 121 is controlled by an adjusting knob 130. A base 140 is provided at the bottom of the second leg 124, and pins are installed at the four corners of the bottom of the base 140. The steel casing 100 is fixed outside the bracket vertical rod 10 through a sleeve 150. The sleeve 150 is formed by connecting two semi-cylindrical cavities through a hinge point 160 and is locked by a screw 170 and a nut 180.

[0028] Before concrete pouring, the steel casing 100 is sleeved on the bracket vertical rod 10. An airbag is installed inside the steel casing 100. One end of the airbag is connected to a hose 310. The position where the hose 310 is connected to the airbag is fixed on the sleeve 150. The sleeve 150 is formed by two semi-cylindrical cavity tubular structures and can be sleeved on the bracket vertical rod 10 through the rotation of the hinge point 160 and is locked by a screw 170 and a nut 180. Side ears 121 are welded to the side of the steel casing 100. The side ears 121 are connected to the first leg 123 through a pin 129, and the rotation angle is controlled by an adjusting knob 130. The top of the second leg 124 extends into the first leg 123. An adjusting screw 125 is embedded on the second leg 124. The adjusting screw 125 is helically connected with a driven gear 126. A driving gear 127 is rotatably connected to one side of the first leg 123. The driven gear 126 meshes with the driving gear 127. By rotating the driving gear 127, the second leg 124 is driven to expand and contract, so as to adjust the length of the second leg 124. The second leg 124 can reciprocally slide along the first leg 123 and be fastened to the first leg 123. The bottom of the second leg 124 is rotatably connected to a base 140 through a pin shaft, and pins are installed at the four corners of the bottom of the base 140 for firmly fixing the steel casing 100 outside the bracket vertical rod 10.

[0029] The present invention also provides a method for monitoring the displacement of the bracket, using the above-mentioned bracket displacement monitoring device, including the following steps: Step 1: Install the steel casing 100 outside the bracket vertical rod 10 and fix the steel casing 100.

[0030] Slip the steel casing 100 of the support displacement monitoring device onto the support vertical rod 10 and ensure that the support vertical rod 10 is centered, and fix it on the outside of the support vertical rod 10 through the sleeve 150. The sleeve 150 consists of two semi-cylindrical cavities connected by a hinge point 160, and is locked by a screw 170 and a nut 180. The telescopic leg 122 is connected to the steel sleeve through a side ear 121 and a pin 129. Shake the crank to lower the second leg 124, move the steel casing 100 to the designated position, and fix the base 140 to the ground to firmly fix the device.

[0031] Step 2: Use the inflation device 200 to inflate the airbag inside the steel casing 100 so that the airbag expands radially and contacts the support vertical rod 10.

[0032] Step 3: When the support vertical rod 10 is displaced, the airbags on the upper and lower sides of the steel casing 100 in the vertical direction are squeezed. The length of the upper airbag is shortened by d, and the length of the upper airbag is shortened by d1. The volume of the airbag is transmitted to the detection device 300 by the squeezed gas.

[0033] The gas in the U-shaped tube 321 corresponding to the upper and lower airbags squeezes the liquid. The height of the liquid level rises by d and d1 respectively. The high-precision infrared rangefinder 322 measures the initial liquid level height as t, and the liquid level heights after squeezing are t1 and t2 respectively. Since the pipe diameters are the same and the gas is insoluble in the liquid, there is t - t1 = d and t - t2 = d1. The high-precision infrared rangefinder 322 transmits the measured liquid level height change data to the sub-data processing module 330 through the input line 370. Store and calculate MAX(t - t2) - (t - t1), which is the verticality in the same vertical direction, and MAX(t - t2) - (t - t1) is the horizontal displacement in the same vertical direction. The sub-data processing module 330 is transmitted to the total data processor 340 through the input line 370 for storage and calculation of all data corresponding to the sub-data processing module 330. MAX[MAX(t - t2) - (t - t1)] is the verticality, and MAX[MAX(t - t2) - (t - t1)] is the horizontal displacement.

[0034] Step 4: The detection device 300 alarms when the volume of the airbag squeezed exceeds the warning value.

[0035] The total data processor 340 transmits the signal to the display 360 for real-time display. When the verticality and horizontal displacement warning values are reached, it is transmitted to the alarm device 350 through the output line 380 for alarm.

[0036] The bracket displacement monitoring device provided by the present invention can achieve automatic monitoring, display monitoring data in real time, and can give an automatic warning, saving labor and providing accurate observation. It can be applied to the detection of steel pipes with different diameters through the inflation and expansion of the airbag. It is fixed on the outside of the vertical pole through the sleeve, without setting a fixed end, and the monitoring bracket vertical pole 10 can be moved through the telescopic sleeve of the support leg to monitor each part. It can ensure the accuracy of the monitoring of the bracket vertical pole 10 under the working condition of uneven site. There is no need for complex wiring, and the installation is simple, reducing the construction difficulty and cost.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
