Description

Technical Field

[0001] This utility model relates to the field of bending resistance testing technology, and more specifically, to a bending resistance testing device for a support beam. Background Technology

[0002] In many fields such as construction and machinery manufacturing, support beams are key structural components, and their bending resistance directly affects the stability and safety of the entire structure. With the continuous development of industrial technology, the requirements for the quality and performance of support beams are becoming increasingly stringent, making accurate testing of their bending resistance an important task in production, manufacturing, and quality control.

[0003] Currently, existing methods and devices for testing the bending resistance of support beams have many shortcomings. Some testing equipment has a simple structure and cannot effectively fix the support beam during the testing process, making it prone to displacement or warping under stress. This not only affects the accuracy of the test results but may also pose safety hazards to operators. For example, some traditional testing devices rely solely on simple clamps to fix the support beam. When pressure is applied, the ends of the support beam are difficult to stably constrain, leading to deviations in the test data.

[0004] Meanwhile, existing testing methods need improvement in terms of accuracy. Most devices cannot accurately measure the degree of bending and the magnitude of pressure on the support beam under different pressures, making it difficult to comprehensively reflect the beam's bending resistance. For example, some testing equipment, when measuring the force on the support beam, fails to fully consider the influence of factors such as friction, resulting in errors between the measured pressure data and the actual force, thus failing to provide a reliable basis for product quality assessment. These problems limit the improvement of support beam production quality.

[0005] Therefore, a device for testing the bending resistance of a supporting beam is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a support beam bending resistance detection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for testing the bending resistance of a supporting beam, comprising a testing cabinet, a placement platform installed inside the testing cabinet, pressure-fixing components installed at both ends of the placement platform, a supporting beam body clamped between the pressure-fixing components and the placement platform, a laser rangefinder installed in the middle of the placement platform, a pressure-applying component installed at the top inside the testing cabinet, a pressure-reducing component installed at the bottom of the pressure-applying component, a cabinet door installed on the testing cabinet, and a display screen installed on the top front of the testing cabinet.

[0008] Preferably, the pressing assembly includes an electric push rod, a pressure plate, guide rods, and a first roller group. The electric push rod is installed at one end of the placement platform, the pressure plate is installed at the top of the electric push rod, two guide rods that are slidably connected to the placement platform are installed at one end of the pressure plate, and the first roller group is installed at the bottom end of the pressure plate.

[0009] Preferably, a second roller group is installed at both ends of the top of the placement platform, and each second roller group is respectively configured to cooperate with the corresponding first roller group.

[0010] Preferably, the pressurization assembly includes a hydraulic pump, a hydraulic rod, a lifting frame, a pressure sensor, and a base plate. The hydraulic pump is installed at the top inside the testing cabinet. The hydraulic pump is connected to the hydraulic rod. The lifting frame is installed at the bottom end of the hydraulic rod. The pressure sensor is installed inside the lifting frame. The base plate is installed at the bottom end of the lifting frame. A sliding hole is provided in the middle of the base plate.

[0011] Preferably, the pressing assembly includes a slider, a connecting rod, a roller frame, and a pressure roller. The slider is slidably connected to the lifting frame, and its top end is connected to a pressure sensor. The bottom end of the slider is equipped with a connecting rod that is slidably connected to a sliding hole. The bottom end of the connecting rod is equipped with a roller frame, and the bottom end of the roller frame is equipped with a pressure roller.

[0012] Preferably, the pressure roller is vertically positioned above the middle of the support beam body, two first roller sets are respectively pressed onto the top of both ends of the support beam body, and two second roller sets are respectively supported at the bottom of both ends of the support beam body.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting pressure-fixing components at both ends of the placement platform, the electric actuator drives the pressure plate to rise and fall, so that the first roller group presses down to support both ends of the crossbeam body. In conjunction with the second roller group at both ends of the top of the placement platform, the end of the support crossbeam body is prevented from tilting up when under stress testing, thus preventing it from breaking out and improving the effectiveness and safety of the test.

[0015] 2. The hydraulic pump in the pressurizing assembly drives the hydraulic rod, causing the pressure roller of the pressing assembly to descend and press against the middle of the supporting beam body. The contact surface between the pressure roller and the supporting beam body is a rolling connection, which reduces the influence of friction on the pressure intensity. The slider is connected to the pressure sensor, which can accurately detect the stress on the supporting beam body and improve the bending resistance detection accuracy.

[0016] 3. When detecting the bending changes of the support beam body after being subjected to force, its two ends are rolled and connected to the first and second roller groups, which can avoid the influence of friction on the detection. The laser rangefinder detects the bending of the support beam body in real time. Combined with the pressure data detected by the pressure sensor, it can accurately detect the deformation changes of the support beam body as the pressure changes, and comprehensively detect its bending force.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figures 1-5 The device shown is a testing device for testing the bending resistance of a supporting beam, including a testing cabinet 1. A placement platform 4 is installed inside the testing cabinet 1. A clamping component 5 is installed at both ends of the placement platform 4. The clamping component 5 and the placement platform 4 clamp the supporting beam body 6. A laser rangefinder 9 is installed in the middle of the placement platform 4. A pressure component 7 is installed at the top inside the testing cabinet 1. A pressing component 8 is installed at the bottom of the pressure component 7. A cabinet door 2 is installed on the testing cabinet 1. A display screen 3 is installed on the top front of the testing cabinet 1.

[0025] In practice, the supporting beam body 6 is placed on the placement platform 4, and the two clamping components 5 press down on both ends of the supporting beam body 6 to prevent the ends of the supporting beam body 6 from tilting up under pressure. After the two ends of the supporting beam body 6 are blocked by the corresponding clamping components 5, the pressurizing component 7 operates, causing the pressing component 8 to descend and press down on the supporting beam body 6. During the pressing process, the pressing component 8 is subjected to the reaction force of the supporting beam body 6, which squeezes the pressure sensor 704 installed in the pressurizing component 7, causing the pressure sensor 704 to detect the supporting beam body 6. During the pressurization process, the laser rangefinder 9 installed on the placement platform 4 continuously monitors the bending of the supporting beam body 6. When the laser rangefinder 9 detects a shortening of the distance between itself and the bottom of the supporting beam body 6, it indicates that the supporting beam body 6 has bent under this force. The pressure data detected by the pressure sensor 704 is fed back to the display screen 3 for direct viewing. As the pressure increases, the laser rangefinder 9 monitors in real time, thereby detecting the deformation changes of the supporting beam body 6 caused by the pressure change, thus enabling a more comprehensive detection of the bending stress of the supporting beam body 6.

[0026] The pressing assembly 5 includes an electric push rod 501, a pressure plate 502, a guide rod 503, and a first roller group 504. The electric push rod 501 is installed at one end of the placement platform 4. The pressure plate 502 is installed at the top of the electric push rod 501. Two guide rods 503 that are slidably connected to the placement platform 4 are installed at one end of the pressure plate 502. The first roller group 504 is installed at the bottom of the pressure plate 502.

[0027] The top two ends of the placement platform 4 are each equipped with a second roller group 10, and each second roller group 10 is respectively configured to cooperate with the corresponding first roller group 504.

[0028] In practice, the extension and retraction of the electric actuator 501 allows the pressure plate 502 to rise and fall, which in turn causes the first roller group 504 to rise and fall accordingly. This causes the first roller group 504 to press down on the end of the support beam body 6 placed on the second roller group 10, thereby preventing the two ends of the support beam body 6 from tilting up during the force detection process, thus preventing the support beam body 6 from breaking off and improving the effectiveness and safety of the detection.

[0029] The pressurization assembly 7 includes a hydraulic pump 701, a hydraulic rod 702, a lifting frame 703, a pressure sensor 704, and a base plate 705. The hydraulic pump 701 is installed at the top inside the testing cabinet 1. The hydraulic pump 701 is connected to the hydraulic rod 702. The lifting frame 703 is installed at the bottom end of the hydraulic rod 702. The pressure sensor 704 is installed inside the lifting frame 703. The base plate 705 is installed at the bottom end of the lifting frame 703. A sliding hole is opened in the middle of the base plate 705.

[0030] The pressing assembly 8 includes a slider 801, a connecting rod 802, a roller frame 803, and a pressure roller 804. The slider 801 is slidably connected to the lifting frame 703. The top of the slider 801 is connected to the pressure sensor 704. The bottom of the slider 801 is equipped with a connecting rod 802 that is slidably connected to a sliding hole. The bottom of the connecting rod 802 is equipped with a roller frame 803. The bottom of the roller frame 803 is equipped with a pressure roller 804.

[0031] The pressure roller 804 is vertically positioned above the middle of the support beam body 6. Two first roller groups 504 are respectively pressed onto the top of both ends of the support beam body 6, and two second roller groups 10 are respectively supported at the bottom of both ends of the support beam body 6.

[0032] In specific implementation, the two ends of the supporting beam body 6 are clamped by the first roller group 504 and the second roller group 10, causing the hydraulic pump 701 to operate and the hydraulic rod 702 to extend. This causes the pressure roller 804 to descend and press against the middle of the supporting beam body 6. The contact surface between the pressure roller 804 and the supporting beam body 6 is in a rolling connection, thus avoiding the influence of friction on the applied pressure during pressing. This allows the slider 801 to abut against the pressure sensor 704, enabling the pressure sensor 704 to accurately detect the force on the supporting beam body 6, thereby improving the accuracy of the bending resistance detection of the supporting beam body 6. As the supporting beam body 6 continues to be subjected to force, when detecting the bending change of the supporting beam body 6 after being subjected to force, the two ends are in a rolling connection with the first roller group 504 and the second roller group 10. Therefore, when the supporting beam body 6 slides towards the middle again, the influence of friction can be avoided, thereby improving the detection accuracy of the bending change of the supporting beam body 6 after being subjected to force.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
