Description

Technical Field

[0001] This utility model relates to the field of deformation detection technology, specifically a deformation detection device for concrete bending members. Background Technology

[0002] Concrete flexural members mainly include beams and slabs, which differ in their structural form and application. Beams are mostly used in bridges with large spans, load-bearing members and force-transferring members in frame structures, while slabs are mostly used in bridge decks with smaller spans, cast-in-place or precast pedestrian walkway slabs, and bridge decks in beam-grid systems. During use, concrete flexural members may deform due to factors such as load, temperature changes, shrinkage, and expansion. Therefore, deformation detection devices are needed to detect and record deformation data.

[0003] In the existing technology, the cross-sectional dimension detection of concrete components requires measuring the dimensions at both ends and the middle of the component separately, and calculating the deviation value between the dimension of each measuring point and the initial specified dimension. The measurement steps are complicated and require the staff to move around and measure multiple times to read the measurement data, which makes it easy to make detection errors.

[0006] As a further preferred embodiment of this technical solution, each of the multiple sets of adjustment frames is fixedly equipped with an installation shaft, and the two sets of cross-distributed connecting rods are rotatably connected to the installation shaft. Both ends of the connecting rods are rotatably connected to the connecting rods set on the adjacent adjustment frames through rotating shafts.

The two sets of spiral tubes pass through corresponding second slide rods and are threadedly connected to the second slide rods respectively. The bidirectional screw is provided with two sets of symmetrically distributed limiting grooves. Two sets of symmetrically distributed limiting blocks are fixedly installed in each of the two sets of spiral tubes. The limiting blocks are correspondingly arranged with the limiting grooves. The spiral tubes are slidably sleeved with the bidirectional screw through the limiting blocks.

[0009] As a further preferred embodiment of this technical solution, a fixing rod is fixedly installed inside the adjusting frame, and two sets of symmetrically distributed clips are rotatably sleeved on the fixing rod.

[0012] This utility model provides a device for detecting the deformation of concrete flexural members, which has the following beneficial effects:

[0013] (1) This utility model achieves synchronous deformation detection of multiple points of bending components by using multiple sets of adjustable frames that are slidably connected on the mounting frame, which simplifies the detection steps of bending components. Since the spacing between the multiple sets of adjustable frames can be adjusted equidistantly according to the actual size of the bending component being detected, the detection device can complete the detection of multiple positions of the bending component at one time. The spacing between the detection points is equal, which ensures the comprehensiveness of the detection data of the bending component and effectively improves the efficiency of the detection work. In addition, the detection device uses the cooperation of infrared ranging sensor, reflector and controller to measure the size of the component, which eliminates the need for staff to manually align the scale and read the value, thus avoiding errors that may be caused by manual measurement.

[0014] (2) This utility model achieves synchronous control of the position between two symmetrically distributed clamps in the positioning seat through the cooperation of the handle and rotating rod, as well as the gear and rack inside the positioning seat. This ensures that the fixed position of the bending component is always in the middle position of the positioning seat, making the fixing of the bending component quick and easy during the detection process, which is convenient for the staff to operate. In addition, the two sets of clamps are relative to each other to ensure that the infrared ranging sensor and the reflector are always in correspondence, thus ensuring the accuracy of data measurement.

Each set of adjusting frames 2 is provided with two sets of cross-distributed connecting rods 12. A positioning seat 14 is provided above the adjusting frame 2. Two sets of symmetrically distributed movable frames 19 are slidably installed inside the mounting frame 14. Each set of movable frames 19 is fixedly equipped with a clamping plate 21. Infrared ranging sensors 29 and reflectors 30 are respectively fixedly installed on the clamping plates 21. The infrared ranging sensors 29 and reflectors 30 are correspondingly arranged. A controller 31 is fixedly installed on the mounting frame 1. Based on the length of the bending member to be detected, the motor in the mounting rod 3 is activated, driving the second bevel gear 11 to rotate. This, in conjunction with the first bevel gear 10, causes the bidirectional screw 6 to rotate. Under the limiting action of the limiting block 9 and the limiting groove 7, the screw tube 8 rotates synchronously, thereby adjusting the two sets of... The spacing between the frame sections 2 is adjusted. Under the action of the connecting rods 12 that are cross-distributed between adjacent sets of adjustment frames 2, the multiple sets of adjustment frames 2 on the mounting frame 1 are equidistantly changed until the two sets of adjustment frames 2 at both ends correspond to the two ends of the component. Each set of adjustment frames 2 is fixedly installed with a mounting shaft 13. The two sets of cross-distributed connecting rods 12 are rotatably connected to the mounting shaft 13. Both ends of the connecting rod 12 are rotatably connected to the connecting rod 12 set on the adjacent adjustment frame 2 through a rotating shaft.

A positioning seat 14 is installed on the adjusting frame 2, and the handle 25, in conjunction with the fourth bevel gear 27 and the third bevel gear 26, drives the rotating rod 23 to rotate. Under the action of gear 24 and two sets of racks 22, the two sets of moving frames 19 drive the clamping plates 21 to move synchronously to both sides, making it convenient for the staff to place the component on the positioning seat 14. After releasing the handle 25, under the action of spring 20 and the second torsion spring 28, the two sets of clamping plates 21 slide synchronously inward, fixing the component in the center position of the positioning seat 14. At this time, the infrared ranging sensor 29 emits an infrared signal of a specific frequency, which is then transmitted through the infrared sensor tube. After reflection by the reflector 30, the reflected infrared signal is received by the receiver tube on the infrared ranging sensor 29 and transmitted to the controller 31 to achieve rapid measurement of the component size. The infrared ranging sensor 29 is a GP2Y0A710K, and the controller 31 is an Arduino. Both sets of clamping plates 21 are slidably connected to the positioning seat 14.

[0024] This utility model provides a deformation detection device for concrete flexural members. The specific working principle is as follows: Based on the length of the flexural member to be detected, the motor in the mounting rod 3 drives the second bevel gear 11 to rotate, which in turn, in conjunction with the first bevel gear 10, causes the bidirectional screw 6 to rotate. Under the limiting action of the limiting block 9 and the limiting groove 7, the screw tube 8 rotates synchronously, thereby adjusting the distance between the two sets of adjusting frames 2 at both ends. Under the action of the connecting rod 12, which is distributed crosswise between adjacent sets of adjusting frames 2, the multiple sets of adjusting frames 2 on the mounting frame 1 undergo equidistant changes until the two sets of adjusting frames 2 at both ends correspond to the two ends of the member. After the distance between the adjusting frames 2 is adjusted, based on the number of points to be detected on the member, the device is connected by the locking block 15 and the locking frame 17. A positioning seat 14 is installed on the adjusting frame 2, and the handle 25, in conjunction with the fourth bevel gear 27 and the third bevel gear 26, drives the rotating rod 23 to rotate. Under the action of the gear 24 and the two sets of racks 22, the two sets of moving frames 19 drive the clamping plates 21 to move synchronously to both sides, making it convenient for the staff to place the component on the positioning seat 14. After releasing the handle 25, under the action of the spring 20 and the second torsion spring 28, the two sets of clamping plates 21 slide inward synchronously, fixing the component in the center position of the positioning seat 14. At this time, the infrared ranging sensor 29 emits an infrared signal of a specific frequency. After being reflected by the reflector 30, the infrared signal reflected back is received by the receiving tube on the infrared ranging sensor 29 and transmitted to the controller 31 to realize the rapid measurement of the component size.
