Description

Technical Field

[0001] This utility model relates to the field of building engineering testing technology, specifically a steel bar bending testing device. Background Technology

[0002] In fields such as construction engineering, the degree of bending of reinforcing bars directly affects the safety of the engineering structure, making its inspection crucial. Currently, traditional methods for detecting reinforcing bar bending have significant limitations: traditional mechanical testing equipment mostly performs single-point or localized inspections, unable to continuously monitor the entire length of the reinforcing bar, easily leading to missed detections. Furthermore, their guiding mechanisms have poor adaptability, requiring frequent component replacements for reinforcing bars of different diameters, and lack effective pre-tightening adjustment, making them susceptible to detection accuracy due to reinforcing bar swaying. Overall, they are unable to comprehensively and accurately reflect the bending condition of the reinforcing bars.

[0003] The core flaw of existing technologies lies in their single detection dimension. They can only judge the bending of steel bars by monitoring displacement in a single direction, and cannot capture the bending deformation of steel bars in different directions. Especially for complex multi-directional bending steel bars, the insufficient detection angle can easily lead to misjudgment or omission. In actual engineering, the bending of steel bars is often multi-directional, and this single-angle detection is difficult to meet the requirements of high-precision quality control. Therefore, there is an urgent need for a device that can realize multi-angle detection to comprehensively improve the accuracy and reliability of steel bar bending detection. Utility Model Content

[0004] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a rebar bending detection device, which solves the problems of limited detection dimensions and poor adaptability of existing rebar bending detection equipment.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A rebar bending detection device includes a support frame, on which a tensioning component and a detection component are mounted. The tensioning component drives the rebar to pass through the detection component along a preset path to achieve bending detection. The detection component includes a detection frame, on which two crossbeams are symmetrically arranged on both the upper and lower sides. A detection unit is arranged between two adjacent crossbeams. A first displacement sensor for detecting the lateral displacement of the detection unit is mounted on the support frame. The first displacement sensor is correspondingly arranged with the detection unit to collect displacement data in real time.

[0007] More preferably, the detection unit includes a first sliding sleeve slidably sleeved on a crossbeam, a first guide wheel fixedly connected to the first sliding sleeve on the lower crossbeam, a second sliding sleeve fixedly connected to the first sliding sleeve on the upper crossbeam, a connecting rod slidingly passing through the interior of the second sliding sleeve, and a second guide wheel fixedly connected to the bottom of the connecting rod.

[0008] More preferably, the curved surfaces of the first guide wheel and the second guide wheel are both provided with annular grooves, and the annular grooves of the first guide wheel and the second guide wheel are aligned vertically to form a detection channel for the passage of the reinforcing bar, and the axis of the detection channel is consistent with the driving direction of the tensioning assembly.

[0009] More preferably, a spring is fitted on the connecting rod, one end of the spring abutting against the bottom of the second sliding sleeve and the other end abutting against the top of the second guide wheel, the spring being used to provide a preload force for the second guide wheel to move closer to the first guide wheel.

[0010] More preferably, a second displacement sensor is fixedly connected to the top of the connecting rod, with the detection end of the second displacement sensor facing the upper crossbeam. The second displacement sensor is used to detect the vertical displacement change between the top of the connecting rod and the upper crossbeam.

[0011] More preferably, the tensioning assembly includes two brackets fixedly installed on a support frame, a screw rotatably connected between the two brackets, and a slide rod parallel to the screw fixedly connected between the two brackets. A pull rod is threaded onto the screw, and the slide rod slides through the pull rod. A clamp for clamping and fixing one end of the reinforcing bar is fixedly installed on the pull rod. A rotary motor is fixedly installed on the support frame, and the output end of the rotary motor is connected to the screw drive.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses a first displacement sensor to detect lateral displacement and a second displacement sensor to detect vertical displacement. Combined with the setting of multiple detection units, it can comprehensively capture the bending deformation of steel bars in different directions, solving the problem of single detection dimension of traditional equipment and greatly improving detection accuracy.

[0014] 2. The present invention uses a tensioning assembly to drive the reinforcing bar to continuously pass through the detection channel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] like Figure 1-4 As shown, a rebar bending detection device includes a support frame 1, which serves as the mounting base for the entire device and provides stable support for each component. The support frame 1 is equipped with a tension component 2 and a detection component 3. The tension component 2 drives the rebar to pass through the detection component 3 along a preset path, enabling continuous conveying of the rebar to complete the bending detection. The detection component 3 is used to monitor the bending deformation of the rebar in real time during the conveying process.

[0025] The detection component 3 includes a detection frame 301. Two crossbeams 302 are symmetrically arranged on both the upper and lower sides of the detection frame 301. A detection unit 4 is positioned between two adjacent crossbeams 302. Through the cooperation of multiple sets of crossbeams 302 and the detection units 4, the bending of the reinforcing bars in different directions can be detected. A first displacement sensor 303 is also installed on the support frame 1, corresponding to the detection unit 4, and is used to collect the lateral displacement of the detection unit 4 in real time, thereby reflecting the degree of bending of the reinforcing bars in the lateral direction.

[0026] The detection unit 4 includes a first sliding sleeve 401 slidably fitted onto a crossbeam 302. A first guide wheel 402 is fixedly connected to the first sliding sleeve 401 on the lower crossbeam 302, and a second sliding sleeve 403 is fixedly connected to the first sliding sleeve 401 on the upper crossbeam 302. A connecting rod 404 slides through the second sliding sleeve 403, and a second guide wheel 405 is fixedly connected to the bottom of the connecting rod 404. The sliding engagement between the first sliding sleeve 401 and the crossbeam 302 allows the detection unit 4 to move with the lateral bending of the reinforcing bar, while the sliding engagement between the second sliding sleeve 403 and the connecting rod 404 allows the second guide wheel 405 to adjust to changes in the diameter of the reinforcing bar or vertical bending.

[0027] Both the first guide wheel 402 and the second guide wheel 405 have annular grooves 407 on their curved surfaces, and these grooves are aligned vertically to form a detection channel for the passage of the reinforcing bar. The axis of the detection channel is consistent with the driving direction of the tensioning assembly 2, ensuring that the reinforcing bar is stably conveyed along a preset path. A spring 406 is fitted on the connecting rod 404. One end of the spring 406 abuts against the bottom of the second sliding sleeve 403, and the other end abuts against the top of the second guide wheel 405. This provides a preload force to bring the second guide wheel 405 closer to the first guide wheel 402, ensuring that the guide wheel is in close contact with the surface of the reinforcing bar and preventing the reinforcing bar from shaking and affecting the detection accuracy.

[0028] A second displacement sensor 304 is fixedly connected to the top of the connecting rod 404. Its detection end is set towards the upper crossbeam 302 to detect the vertical displacement change between the top of the connecting rod 404 and the upper crossbeam 302, thereby reflecting the degree of bending of the steel bar in the vertical direction.

[0029] The tensioning assembly 2 includes two brackets 201 fixedly mounted on the support frame 1. A screw 202 is rotatably connected between the two brackets 201, and a slide rod 203 parallel to the screw 202 is fixedly connected to it. A pull rod 204 is threaded onto the screw 202, and the slide rod 203 slides through the pull rod 204, which restricts the pull rod 204 from rotating synchronously with the screw 202, ensuring that the pull rod 204 moves smoothly along the axial direction. A clamp 205 is fixedly mounted on the pull rod 204 for clamping and fixing one end of the reinforcing bar. A rotary motor 206 is fixedly mounted on the support frame 1, and its output end is connected to the screw 202 for transmission. By driving the screw 202 to rotate, the pull rod 204 is moved, realizing the tensioning and conveying of the reinforcing bar.

[0030] Working principle:

[0031] Based on the diameter of the reinforcing bar to be tested, select a spring 406 with a suitable elastic coefficient and install it on the connecting rod 404 to ensure that the preload of the spring 406 is compatible with the diameter of the reinforcing bar; set parameters such as the reinforcing bar conveying speed through an external control system.

[0032] One end of the reinforcing bar is placed in the clamp 205 of the tensioning assembly 2, and the clamp 205 is controlled to clamp the end of the reinforcing bar. The reinforcing bar passes through the detection channel of the detection assembly 3 (i.e., between the annular groove 407 of the first guide wheel 402 and the second guide wheel 405). At this time, the spring 406 pushes the second guide wheel 405 downward to press the reinforcing bar tightly, so that the reinforcing bar and the annular groove 407 fit tightly together.

[0033] Start the rotary motor 206, which drives the screw 202 to rotate, causing the pull rod 204 to move axially along the slide rod 203, thereby pulling the steel bar to be conveyed at a constant speed along the detection channel.

[0034] During the rebar conveying process, if the rebar is laterally bent, it will push the first guide wheel 402 and the second guide wheel 405 to move laterally synchronously, causing the first sliding sleeve 401 to slide along the crossbeam 302. The first displacement sensor 303 detects the lateral displacement of the first sliding sleeve 401 in real time and transmits it to the control system. If the rebar is vertically bent or has a diameter deviation, it will push the second guide wheel 405 to move up and down, causing the connecting rod 404 to slide along the second sliding sleeve 403. The second displacement sensor 304 detects the vertical displacement of the connecting rod 404 in real time and transmits it to the computer. The computer analyzes the lateral and vertical displacement data and calculates parameters such as the bending position and degree of bending of the rebar.
