Description

Technical Field

[0001] The utility model relates to the technical field of bridge settlement monitoring, in particular to a bridge settlement monitoring instrument. Background Art

[0002] With the development of the transportation industry, there are more and more bridge construction projects. The scaffolding method is one of the main construction methods for bridge construction. When the scaffolding method is used for construction, multiple bridge scaffolds need to be erected at certain intervals along the longitudinal direction of the bridge being constructed.

[0003] The bridge support is the supporting foundation during the construction of the bridge. The structural stability, safety and quality of the bridge support directly affect the quality and construction period of the bridge construction, and are also directly related to the personal safety of the construction workers. Therefore, the structural stability and safety of the bridge support must be guaranteed. However, the bridge support is immersed in water for a long time and is impacted by the water flow. After long-term scouring, the support is easily aged and damaged, and after long-term use, it is easy to cause safety accidents. Therefore, it is necessary to monitor the settlement of the bridge support.

[0004] There are some monitoring devices for bridge settlement on the market. However, when installing the equipment, the equipment is installed on the bridge by bundling or fixing. Since the equipment cannot rotate around the bridge, the transmission direction of the signal transmitter of the equipment is single, and it is impossible to monitor its accurate settlement information in all directions.

DETAILED DESCRIPTION

[0021] The utility model provides a bridge settlement monitoring device, such as Figure 1-3 As shown, it includes a monitor and at least one reference.

[0022] like Figure 3As shown, the monitor includes two semicircular rings 1, a bracket 3, a gear 4, a motor 5 and a laser emitter 6. The two semicircular rings 1 are detachably connected. The two semicircular rings 1 are provided with toothed rings 2 that can be combined with each other to form an annular tooth path. The toothed rings 2 are located at the upper half of the semicircular rings 1. A connecting plate 14 is provided at the joint of the lower half of the two semicircular rings 1. The connecting plate 14 is provided with corresponding connecting holes. The two connecting plates 14 are connected by connecting bolts 15. When the two semicircular rings 1 are combined with each other, the two toothed rings 2 structure constitute a complete closed toothed ring for the gear 4 to move in an annular direction.

[0023] The bracket 3 is L-shaped, the gear 4 is pivoted at the bottom of the bracket 3 and meshes with the gear ring 2, the motor 5 is arranged at the top of the bracket 3 and connected to the gear 4, in order to enable the bracket 3 to be guided along the semicircular ring 1, a ring track 7 is arranged at the top of the semicircular ring 1, and a slider 8 is arranged on the bracket 3 to slide in the ring track 7. The laser emitter 6 is arranged on the side of the bracket 3, and the laser emitter 6 is an existing commercial product for emitting a laser beam. When the gear 4 rotates, due to the existence of the guide ring track 7, the gear 4 moves along the gear ring 2 in the ring direction.

[0024] The two semicircular rings 1 are used to wrap around the tubular support at the top of the bridge. Since most of the tubular support is made of steel, in order to match tubular supports of different diameters, the lower halves of the two semicircular rings 1 are radially slidably adapted with connecting rods 17. Two sets of connecting rods 17 are provided with corresponding clamping plates 16 on one end located inside the semicircular ring 1, and a spring 18 is sleeved on a section of the connecting rod 17 located inside the semicircular ring 1. A limit block is provided on one end of the connecting rod 17 located outside the semicircular ring 1. When the two semicircular rings 1 are sleeved outside the tubular support, the positions of the two clamping plates 16 can be adjusted by adjusting the two connecting rods 17 to clamp the tubular support. The clamping plate 16 is a magnet, and the clamping plate 16 made of magnet material can be more conveniently adsorbed and fixed on the tubular support.

[0025] In order to adapt to bridges of different shapes, the inner wall shape of the semicircular ring 1 can be set to a rectangular shape so that it can be clamped on a concrete bridge with a fixed rectangular structure.

[0026] like Figure 1 As shown, the reference device includes a column 9, a mounting seat 10 and a marking ring 12. The mounting seat 10 is arranged at the bottom of the column 9. The mounting seat 10 is provided with a plurality of fixing holes for drilling and fixing on the reference body, which can be a road surface separated from the bridge deck. The column 9 is provided with a scale 11 along its length direction. The marking ring 12 is vertically slidably adapted on the column 9. The marking ring 12 is transversely threaded with a fixing bolt 13 corresponding to the column 9. When the fixing bolt 13 is tightened, the marking ring 12 can be locked at any height of the column 9. The laser emitter 6 corresponds to the marking ring 12.

[0027] Working principle: first fix the two semicircular rings 1 of the monitor on the bridge to be monitored, then prepare multiple reference devices, and install them on the road surface or other stable carriers away from the bridge deck at multiple angles along the circumference of the monitor, then use the laser transmitter 6 to illuminate the scales on several reference devices respectively, record and lock the marking ring 12 on the corresponding reference device to the scale value, and determine it as the reference scale. After a period of monitoring, the laser transmitter 6 will emit a laser beam toward each reference device, and record the scales on each column 9; record and analyze: if the scale difference on each reference device is consistent, it means vertical settlement, if the scale difference on each reference device is inconsistent, it is necessary to estimate the tilt direction and tilt angle in detail (the calculation method is a mathematical formula, not the protection center of gravity of this case).

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
