Description

Technical Field

[0001] The utility model belongs to the field of roads and bridges, and more specifically, particularly relates to a road settlement deformation detection device. Background Art

[0002] The settlement measurement of road bridges is to monitor the deformation of bridge structures by setting strain gauges in bridge structures, and then calculate the settlement of bridges, which provides important technical support and data reference for project acceptance and bridge operation and maintenance management. At present, the main methods used for settlement monitoring include leveling and total station methods. The leveling method is to connect the liquid pipes of multiple groups of static level gauges at measuring points in series, and use the pressure change of the liquid in this process to represent the settlement value of the point. When the static level gauge at the measuring point is used as a measuring device, it is fixed to the pier position where the settlement occurs by anchor bolts. When heavy vehicles pass through the bridge pavement, it often causes vertical vibration of the bridge body. When the vibration is transmitted to the pier, the static level gauge will resonate with the pier, affecting the real-time detection effect of the static level gauge and destroying the accuracy of the detection data. Since the static level gauge is anchored, if the static level gauge at the measuring point needs to be replaced and maintained, the surface structure of the pier will be damaged when the static level gauge is disassembled. It can be seen that the disassembly and assembly operation is extremely inconvenient. Utility Model Content

It is welded to the fixing frame 1; the driving gear 12 is welded to the outer side of the transmission rod 17; a through hole is provided at the center of the fixed splint 4, and the top end of the transmission rod 17 is rotatably connected to the through hole of the fixed splint 4; there are two groups of driven gears 11, and the driven gears 11 are respectively meshed and connected to the left and right sides of the driving gear 12, and the driven gears 11 are welded to the outer side of the threaded rod 9; the static level 13 is placed between the movable splint 3 and the fixed splint 4; the fixed baffle 14 is connected to the upper side of the fixed splint 4 by bolts; the limit baffle 5 is connected to the upper side of the fixed splint 4 by fixing bolts 10; the rubber sleeve 15 is bonded to the fixed splint 4, and the rubber sleeve 15 is bonded to the movable splint 3.

[0023] When the utility model is performing level detection and installation work, the fixing frame 1 is anchored at the detection position of the cement pier of the road bridge by anchor nails during the construction of the cement pier. During the detection and installation, the static water level 13 is placed on the anti-skid pad 16 bonded on the upper side of the fixed splint 4, and the rear side of the static water level 13 is tightly attached to the front side of the fixed baffle 14. Then the clamping knob 6 is manually rotated, and the clamping knob 6 drives the active gear 12 welded and connected to the outer side of the transmission rod 17 to rotate. Since the two groups of driven gears 11 are meshed and connected with the active gear 12, the active gear 12 drives the two groups of driven gears 11 to rotate synchronously, and the driven gears 11 respectively drive the two groups of threaded rods 9 to rotate synchronously. Since the outer side of the threaded rod 9 is threadedly meshed and connected in the threaded through hole of the movable splint 3, the threaded rod 9 drives the movable splint 3 to move downward until the anti-skid pad 16 on the lower side of the movable splint 3 is tightly attached to the static water level 13.

The four corners of the lower side surface of the movable splint 3 are provided with convex column structures, and each group of convex columns is provided with a through hole structure that passes through from top to bottom. The guide rod 8 is inserted into the convex column through hole of the movable splint 3, and the movable splint 3 slides directionally along the guide rod 8.

[0025] In the disclosed embodiment, the four corners of the upper side surface of the fixed splint 4 are provided with a convex column structure, and each group of convex columns is provided with a through hole structure that passes through from top to bottom. The guide rod 8 is inserted into the through hole of the convex column of the fixed splint 4, so that the fixed splint 4 cooperates with the movable splint 3 to clamp the hydrostatic level 13 carried thereon and slides directional and damped relative to the guide rod 8. The upper side surface of the fixed splint 4 is provided with two groups of symmetrically distributed through hole structures, and the non-threaded surface at the bottom of the threaded rod 9 is rotatably connected in the through hole of the fixed splint 4, so that the clamping knob 6 on the bottom side of the fixed splint 4 drives the driven gear 11 and the driving gear 12 to form a gear meshing connection structure and synchronously drive the two groups of threaded rods 9 to rotate. The clamping and installation operation of the hydrostatic level 13 is simple and quick. Three groups of threaded through holes are provided on the upper side surface of the fixed splint 4 near the front end, and the fixing bolts 10 are screwed into the threaded through holes of the fixed splint 4.

[0026] In the disclosed embodiment, there are eight groups of rubber sleeves 15, and each four groups of rubber sleeves 15 are respectively bonded to the convex column through holes of the movable splint 3 and the fixed splint 4. Each group of rubber sleeves 15 is a cylindrical structure that passes through from top to bottom. The rubber sleeves 15 are nested on the outer side surface of the guide rod 8. The rubber material of the rubber sleeves 15 increases the contact friction coefficient between the outer side surface of the guide rod 8 and the inner side surface of the rubber sleeve 15 cylinder, which has the effect of reducing the amount and damping the loss, so that the rubber sleeves 15 cooperate with the spring 7 to perform shock absorption and energy absorption.

[0028] In the disclosed embodiment, there are two groups of anti-skid pads 16, and each group of anti-skid pads 16 is made of rubber material only. The anti-skid pads 16 are respectively bonded to the upper side surface of the fixed splint 4 and the lower side surface of the movable splint 3, so that when the fixed splint 4 and the movable splint 3 clamp the hydrostatic level 13, the two groups of anti-skid pads 16 are tightly attached to the upper side surface and the lower side surface of the hydrostatic level 13, increasing the contact surface friction, preventing the hydrostatic level 13 from slipping out due to external force vibration when clamped by the fixed splint 4 and the movable splint 3, thereby improving the clamping stability.

[0029] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, and can be implemented as long as it can achieve its beneficial effects.
