Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection, in particular to a bridge displacement detection machine. Background Art

[0002] Bridges are generally composed of superstructures, substructures, supports and auxiliary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles. The substructure includes abutments, piers and foundations. The supports are force transmission devices installed at the supporting places of the span structure and the piers or abutments. At the same time, piers are added at the connection between the two beams for support. When the piers support the beams, the beams will be displaced horizontally and settled longitudinally due to long-term driving. In more serious cases, the beams and piers may fall off. Therefore, it is necessary to detect the displacement of the beams in the bridge so as to inspect and repair the bridge in time.

[0003] For example, the Chinese utility model patent with patent number 202223512070.4 provides a bridge longitudinal displacement deformation detection device. When in use, the device can detect the longitudinal displacement of the bridge. Through the setting of support plates, touch alarms, touch switches and touch plates, when the longitudinal displacement of the beam exceeds the maximum longitudinal displacement that it can bear, an alarm can be issued in time, thereby reminding the staff to take timely response measures.

[0004] However, existing devices for detecting bridge displacement can generally only detect the displacement of the beam and slab in a single direction, and most of them cannot simultaneously detect the horizontal and longitudinal displacements of the bridge beam and slab, resulting in a decrease in the practicality and functionality of traditional detection devices. Utility Model Content

[0006] To achieve the above purpose, the utility model provides the following technical solution: a bridge displacement detection machine, used to detect the displacement of bridge beams and slabs, comprising:

[0007] A mounting frame, wherein the mounting frame is provided on the mounting frame;

[0008] Clamping plates are provided in two groups and are arranged on the installation frame in a liftable manner. The installation frame is provided with a driving mechanism for driving the two groups of clamping plates to open and close to clamp the beam plate;

[0017] The first electric suction cups are provided in two groups, which are respectively arranged at one end of the two groups of movable frames and are respectively adsorbed to the side surfaces of the two adjacent groups of beams and plates.

[0034] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0035] Example:

[0036] like Figure 1 , 2 As shown, the utility model provides a bridge displacement detection machine for detecting the displacement of bridge beams and slabs, including a mounting frame 101, a mounting frame 102 is arranged on the mounting frame 101, two groups of liftable clamping plates 103 are arranged on the mounting frame 102, and a driving mechanism for driving the two groups of clamping plates 103 to open and close to clamp the beams and slabs is arranged on the mounting frame 101, and the driving mechanism includes a first telescopic member 104 fixedly arranged on the mounting frame 101, and the end of the first telescopic member 104 is hinged to multiple groups of connecting rods 105, and the other ends of the multiple groups of connecting rods 105 are respectively hinged to the two groups of clamping plates 103.

[0037] When installing the detection machine, the first telescopic member 104 can be controlled to extend and retract, and the two groups of clamping plates 103 can be driven to open and close through the cooperation of multiple groups of connecting rods 105. After the two groups of clamping plates 103 are closed, the detection machine can be fixed on the protruding position of the beam or the outer side of the pier, so that the detection machine can be installed and fixed conveniently and quickly.

[0038] like Figure 1 , 2 As shown, in this embodiment, a horizontal displacement detection mechanism is provided on one group of clamps 103, and the horizontal displacement detection mechanism is connected to an adjacent group of beam-slab side surfaces to measure the horizontal displacement of the beam-slab. The horizontal displacement detection mechanism includes a detection frame 203 slidably provided on one group of clamps 103, and both ends of the detection frame 203 are provided with movable frames 204 slidably connected along their axes, and one end of the two groups of movable frames 204 are provided with a first electric suction cup 205, and the two groups of first electric suction cups 205 are respectively adsorbed to the two adjacent groups of beam-slab side surfaces.

[0039] After the detection machine is installed, the two groups of first electric suction cups 205 can be controlled to be powered on so that the two groups of first electric suction cups 205 are respectively attached to the sides of two adjacent groups of beams and slabs. When one group of beams and slabs is displaced, one group of first electric suction cups 205 can be driven to move, so that the movable frame 204 moves in the detection frame 203, and a slide groove 206 is provided on the detection frame 203 along the extension direction of its axis. An indicator block 207 is provided on the movable frame 204, and the indicator block 207 is slidably stuck in the slide groove 206. A first scale line 208 is provided on one side of the slide groove 206. The movement distance of the first electric suction cup 205 can be accurately known by the reading of the indicator block 207 on the first scale line 208, so as to detect the horizontal displacement of the beam and slab. When the device is fixed on the beam and slab, the horizontal displacement of a group of adjacent beams and slabs can be detected. When the device is fixed on the protrusion on the pier, the horizontal displacement of two adjacent groups of beams and slabs can be detected.

[0040] like Figure 1 , 2 As shown, in this embodiment, a vertical plate 201 is provided on the clamping plate 103, and a second telescopic member 202 is fixedly provided on one side of the vertical plate 201, and the telescopic end of the second telescopic member 202 is connected to the detection frame 203. The detection frame 203 can be driven to slide on the clamping plate 103 by controlling the telescopic movement of the second telescopic member 202, thereby pushing the two groups of first electric suction cups 205 to move, so that when the installation position of the detection machine deteriorates, the first electric suction cups 205 can still be adsorbed on the side of the beam plate. And the first electric suction cup 205 can be lifted and slidably arranged at the end of the movable frame 204. When the beam plate undergoes longitudinal displacement, it can drive a corresponding group of first electric suction cups 205 to lift and slide at the end of the movable frame 204, thereby preventing the lifting and displacement of the beam plate from causing the first electric suction cup 205 to fall off, thereby improving the practicality of the detection machine.

[0041] like Figure 1 , 2 As shown, in this embodiment, the longitudinal displacement detection mechanism includes a first connecting seat 301 arranged at the bottom of another group of splints 103, a second scale line 302 is arranged on the first connecting seat 301, a movable seat 303 is arranged at the bottom of the splint 103, a second connecting seat 306 is arranged on the movable seat 303, the second connecting seat 306 is hinged to the first connecting seat 301, a pointer 307 is arranged on the hinge point of the second connecting seat 306 with the first connecting seat 301, and third telescopic parts 304 are arranged at both ends of the movable seat 303, and third suction cups 305 are arranged on both groups of third telescopic parts 304, and one group of third suction cups 305 is adsorbed on the bottom of an adjacent group of beams and plates.

[0042] After the detection machine is installed, one group of the third telescopic parts 304 can be controlled to extend to drive one group of the third suction cups 305 to be adsorbed on the bottom of a group of beams adjacent to the beam fixed by the detection machine. When one group of beams undergoes longitudinal displacement, relative displacement occurs between the two adjacent groups of beams or between the beams and the piers, so that the third suction cups 305 move to drive the movable seat 303 to rotate along the hinge point of the first connecting seat 301 and the second connecting seat 306, thereby driving the pointer 307 to rotate, so that the longitudinal displacement distance of the beam can be known through the coordination between the pointer 307 and the second scale line 302.

[0043] Specific usage and beneficial effects of the utility model:

[0044] When the detector is in use, the two groups of clamps 103 can be controlled to open and close by the driving mechanism, so that the detector is fixed on one of the beams, which is convenient for installation and fixation of the detector, and it can also be fixed on the bridge pier for use. After the detector is fixed, the horizontal displacement detection mechanism and the longitudinal displacement detection mechanism are connected to an adjacent group of beams. When one group of beams is horizontally displaced, the two groups of beams or the beams and the bridge piers are relatively displaced in the horizontal direction, and the horizontal displacement is detected by the horizontal displacement detection mechanism. When one group of beams is longitudinally displaced, the two groups of beams or the beams and the bridge piers are relatively displaced in the vertical direction, and the longitudinal displacement is detected by the longitudinal displacement detection mechanism. Thus, the detector has the function of simultaneously detecting the horizontal displacement and longitudinal displacement of the bridge beams, which improves the practicality and functionality of the detector.

[0045] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
