Description

Technical Field

[0001] This utility model relates to the field of highway bridge inspection technology, and more specifically, to a highway bridge bearing deformation detection device. Background Technology

[0002] When constructing a bridge, piers need to be poured at the bottom of the road surface in advance. Piers are substructures that support the bridge span and transfer dead load and vehicle live load to the foundation. Abutments are located on both sides of the bridge, with piers situated between the abutments. The function of the piers is to support the bridge span structure, while the abutments, in addition to supporting the bridge span structure, also connect to the embankment and prevent embankment landslides. To protect the abutments and embankment fill, protective and diversion works are often constructed on both sides of the abutments.

[0003] Current bridge bearing inspection work is usually carried out by manual observation or by measuring instruments around the bridge bearing. For some minor deformations of cylindrical bridge bearings, it is difficult to measure them accurately by hand, resulting in poor accuracy of bridge bearing inspection. At the same time, the manual measurement process is complicated and cumbersome, requiring a lot of time and effort, resulting in low efficiency of bridge bearing inspection.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A deformation detection device for highway bridge bearings includes a chassis 1. An electric telescopic rod 2 is mounted on the upper side of the chassis 1. One end of the electric telescopic rod 2 is connected to the chassis 1, and the other end of the electric telescopic rod 2 is mounted on a mounting plate 3. A mounting frame 4 is fixedly mounted on the outer side of the mounting plate 3. Two sets of measuring discs 5 are movably mounted on the outer side of the mounting frame 4. Each set of measuring discs 5 has a mounting groove 6 on its upper side. An arc-shaped slide rail 7 is fixedly mounted inside the mounting groove 6. An arc-shaped slide frame 8 is movably mounted outside the arc-shaped slide rail 7. A mounting rod 9 is fixedly mounted on the upper side of the arc-shaped slide frame 8. A distance measuring component 10 is fixedly mounted on the outer end of the mounting rod 9. A first motor 11 is fixedly mounted inside the mounting groove 6. The power end of the first motor 11 is fixedly mounted on... There is a rotating rod 12, with a gear 13 fixedly installed on the outer end of the rotating rod 12. A gear plate 14 is fixedly installed on the inner side of the arc-shaped sliding frame 8, and the gear plate 14 meshes with the gear 13. A moving mechanism for docking the measuring disk 5 is provided on the inner side of the mounting frame 4. A power supply system for docking the ranging component 10 is provided on the outer side of the arc-shaped sliding frame 8, which can provide power to the ranging component 10 independently, thereby ensuring that the ranging component 10 can move normally. At the same time, the ranging component 10 can send the measured data to the client. The staff can view the data through the monitor, which improves the detection efficiency and accuracy. The ranging component is mainly composed of a rangefinder, and its operating principle is a common existing technology, so it will not be described in detail.

[0029] Specifically, the moving mechanism includes a lead screw 15 rotatably disposed inside the mounting frame 4. The lead screw 15 has two threads in opposite directions on its outer side, and each of the two threads in opposite directions on the outer side of the lead screw 15 is fitted with a movable block 16. Both sets of movable blocks 16 movably pass through the mounting frame 4 and extend to the outside. The outer part of the movable block 16 located outside the mounting frame 4 is fixedly connected to the measuring plate 5. The lead screw 15 has a locking effect on the movable block 16, thereby ensuring the installation stability of the measuring plate 5.

[0030] Furthermore, a second motor 17 is fixedly installed on the outside of the mounting frame 4. The power end of the second motor 17 is movably connected to the lead screw 15 through the mounting frame 4. By turning on the second motor 17, the movable block 16 and the measuring disk 5 can be easily moved, so that the two sets of measuring disks 5 can be quickly combined together for measurement. At the same time, after the test is completed, it is also convenient to quickly remove the measuring disk 5 from the bridge support.

[0031] It is worth noting that a through groove 18 for docking the movable block 16 is provided on the outer side of the mounting frame 4. The through groove 18 not only facilitates the movement of the movable block 16, but also limits the movement of the movable block 16, so that when the lead screw 15 rotates, it can drive the movable block 16 to move along the lead screw 15, thereby driving the measuring disk 5 to move.

[0032] It is worth noting that a limiting ring 19 is fixedly installed on the inner side of the arc-shaped slide frame 8, and a limiting groove 20 for engaging the limiting ring 19 is opened on the outer side of the arc-shaped slide rail 7. When the arc-shaped slide frame 8 moves, it can drive the limiting ring 19 to rotate in the limiting groove 20, thereby facilitating the movement of the arc-shaped slide frame 8 while ensuring the installation stability of the arc-shaped slide frame 8.

[0033] In addition, multiple sets of fixing blocks 21 are fixedly installed on the outer side of the chassis 1. Each set of fixing blocks 21 is movably equipped with a fixing cone 22. The fixing cone 22 is threaded through the fixing block 21 and extends to the lower side. By rotating the fixing cone 22, the fixing cone 22 moves towards the lower side of the chassis 1 and inserts into the soil, which can fix the chassis 1 and improve the overall stability of the device.

[0034] Working principle: First, two sets of measuring discs 5 are placed on the outside of the bridge bearing. Then, the second motor 17 is turned on by an external power source to drive the lead screw 15 to rotate. At this time, the two sets of movable blocks 16 sleeved on the outside of the lead screw 15 move simultaneously along the lead screw 15 under the limiting action of the through groove 18. When the movable blocks 16 move, they drive the measuring discs 5 to move, so that the two sets of measuring discs 5 are combined together. Then, the first motor 11 is turned on by an external power source to drive the rotating rod 12 and the gear 13 to rotate. The gear 13 drives the gear plate 14 to rotate, which in turn drives the two sets of arc-shaped sliding frames 18 to rotate. When the arc-shaped sliding frames 18 rotate, they drive the ranging component 10 to rotate. The ranging component 10 can detect the outside of the bridge bearing and send the measured data to the receiving end, so as to more intuitively detect the bridge bearing and improve the accuracy of the detection.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
