Description

Technical Field

[0001] This utility model relates to the technical field of concrete testing devices, and more specifically, to an automated testing device for the impact resistance of concrete. Background Technology

[0002] Concrete is widely used as a building material due to its abundant material sources, good plasticity before construction, and high strength and excellent durability after hardening. However, concrete is also brittle during use. Even high-strength prestressed concrete pipe piles, which use high-strength concrete with a strength grade ≥ C80, are prone to problems such as head bursting during the impact hammering process during pile driving. Therefore, it is necessary to use appropriate equipment to test the impact resistance of both ordinary and high-strength concrete.

[0003] Existing concrete impact testing apparatuses are manufactured according to the requirements and specifications in CECS13-2009 "Standard for Test Methods of Fiber Reinforced Concrete". Therefore, these apparatuses typically include a mounting frame, where the impact ball is locked in place using an electromagnet or mechanical locking mechanism before being released to allow free fall and impact testing. However, this apparatus has the following problems during use:

[0004] (1) After the impact ball hits the test block, it will fly around randomly, which increases the chance of accidental injury. At the same time, the impact ball itself is heavy and needs to be manually placed back to the test height release position, which is quite troublesome.

[0005] (2) Existing devices judge the impact resistance of concrete by the number of impacts when the concrete cracks by impacting the impact ball. However, the number of impacts in existing devices can only be counted manually, which is prone to errors and requires a large amount of work. Especially for high-strength concrete, the number of impacts required to reach the cracking point can be as many as several hundred, which will greatly reduce efficiency and increase error.

[0006] (3) During the process of impacting concrete with the existing device, debris is scattered. The concrete test blocks after being impacted are thrown away manually. The impact position of the impact ball on the test blocks is not fixed. The process is time-consuming, and it is prone to environmental pollution due to errors.

[0007] In view of the above, this application is hereby submitted. Utility Model Content

[0008] The technical problem this invention aims to solve is that after the impact ball impacts the test block, it splashes randomly and requires manual repositioning. The only way to prevent cracking and maintain the test progress is by manually counting the number of impacts. This results in flying debris and dust from the concrete test block, and the impact position of the impact ball is not fixed, leading to deviations. The goal is to provide an automated testing device for the impact resistance of concrete. This device uses a fully automatic robotic arm to capture, adsorb, adjust the position and height of the metal impact ball, release it, allow it to fall freely, and control the impact process, achieving automation and significantly saving testing time. Furthermore, it eliminates the need for manual resetting, enabling automatic resetting.

[0009] This utility model is achieved through the following technical solution:

[0010] An automated testing device for the impact resistance of concrete includes a control device and a testing device;

[0011] The testing device includes a fully automatic robotic arm and a metal impact ball. The fully automatic robotic arm is equipped with a capture chip, and the metal impact ball is equipped with a positioning chip. The fully automatic robotic arm is electrically connected to the control device through a first control switch.

[0012] The capture chip, under the control of the control device, captures the position of the metal impact ball fed back by the positioning chip;

[0013] The control device drives the fully automatic robotic arm to move to the metal impact ball, where it is attracted by electromagnetic means and moved to the test height. Alternatively, the control device drives the fully automatic robotic arm to disconnect the electromagnetic force, causing the metal impact ball to detach from the fully automatic robotic arm and fall freely.

[0014] This invention employs a fully automated robotic arm, which can complete the capture, adsorption, position and height adjustment, release, free fall, and impact process of the metal impact ball, achieving automation and greatly saving testing time. At the same time, it can achieve automatic reset without the need for manual reset.

[0015] In use, the fully automatic robotic arm, after activating the first control switch, utilizes its built-in capture chip to quickly capture the position of a metal impact ball with an internal positioning chip. The control program then initiates the capture function. After capture, the fully automatic robotic arm moves to the metal impact ball and activates the electromagnetic device, causing the metal impact ball to adhere to the electromagnetic device of the fully automatic robotic arm. The fully automatic robotic arm then moves the metal impact ball to a preset test height, disconnects the electromagnetic device, and the metal impact ball undergoes free fall until it impacts the surface of the test block. By repeating the above operations, the capture, adsorption, position adjustment, release, free fall, and impact processes of the metal impact ball can be automatically completed, thereby achieving the test of the impact resistance performance of the test block.

[0016] The control device in this utility model can be electrically connected to the device components of this application using an existing PLC logic control program, and the fully automatic robotic arm can be an existing industrial robotic arm. The inventive point of this application does not involve improving the control program itself. The inventive point of this application is to connect various devices through existing logic control programs to realize the automation process of impact resistance testing.

[0017] In one specific embodiment, the front end of the fully automatic robotic arm is equipped with an electromagnet, and the adsorption and release of the metal impact ball are achieved by energizing and de-energizing the electromagnet.

[0018] In one specific embodiment, the test apparatus further includes a test bench, on which a test block positioning structure is provided. The test block positioning structure includes a test block positioning baffle surrounding the test bench. The test block positioning baffle surrounds a positioning space with a top opening, and the positioning space is used to place the test block.

[0019] This invention can fix, position, and limit the test block by setting a test block positioning baffle, which can ensure that the test block will not move during repeated impacts and always keep the metal impact ball hitting the same position, resulting in more accurate test results.

[0020] In one specific embodiment, the test block positioning baffle is further surrounded by a barrier, the height of which is higher than that of the test block positioning baffle. This prevents the debris generated during the concrete test from flying everywhere during the impact, reducing safety hazards and avoiding environmental pollution. At the same time, it confines the debris inside the barrier, making it easier to clean up the concrete debris later.

[0021] In one specific embodiment, the test bench is provided with a first vertical support frame and a second vertical support frame. The first vertical support frame and the second vertical support frame are respectively located on both sides of the test block positioning structure. A laser emitter is installed on the side of the first vertical support frame facing the test block positioning structure, and a laser targeting device is installed on the side of the second vertical support frame facing the test block positioning structure. The laser counter is equipped with an independent power supply and a wireless connection module. The laser emitter and the laser targeting device are electrically connected to the digital display screen and the control device through a second control switch.

[0022] This invention features a laser emitter. When the metal impact ball falls freely past the laser emitter, the laser target instrument cannot collect the laser light, thus counting once. When the fully automatic robotic arm starts to capture the metal impact ball, the laser counting program stops working and the counting function is not activated. This cycle repeats until the test is completed, achieving automatic counting of the number of impacts. This invention uses a laser counting device; each time the metal ball falls freely past the emitter, it is counted once, eliminating the need for manual counting and achieving automated counting, making the test results more accurate.

[0023] In one specific embodiment, a high-definition camera is also installed on the side of the first vertical support frame facing the test block positioning structure. This invention, by using a high-definition camera, allows the camera to capture real-time images of the test sample surface after the metal impact ball freely falls and impacts the sample surface. These images are simultaneously uploaded to the control device, which then compares them in real-time with a pre-set image of the test surface at the end of the test. The comparison result is fed back to the control device to determine whether the test is complete and whether the program needs to continue. If the image of the test sample surface matches the image of the completed test sample surface, the entire test is complete, the program stops, and the corresponding test result is output. If they do not match, the fully automatic robotic arm starts again to conduct the next impact test, achieving fully automated impact testing without human intervention.

[0024] In one specific embodiment, a vibration sensor is also provided on the test bench, and the vibration sensor is electrically connected to the control device. The vibration sensor can determine whether the metal impact ball has struck the test block. If it is determined that the ball has struck the test block, the fully automatic robotic arm can be activated to continue to complete the repeated test process of capturing, adsorbing, adjusting the position and height of the metal impact ball, releasing it, and subjecting it to free fall impact.

[0025] In one specific embodiment, the second vertical support frame has a telescopic structure, which allows the second vertical support frame to be extended or shortened in the vertical direction. The second vertical support frame also has a scale, which allows the second vertical support frame to be extended and shortened in the vertical direction, so that the operator can visually observe the release height of the metal impact ball through the scale.

[0026] In one specific embodiment, the test bench in the positioning space is provided with a metal plate that can be flipped downwards, and the automated testing device also includes a recycling device, which includes a waste recycling container located below the metal plate.

[0027] The metal plate of this invention can be opened or closed freely downwards. After the test is completed, the waste concrete test block can be opened downwards through the metal plate and fall directly into the waste recycling container below, which can achieve environmentally friendly and convenient recycling of the test block.

[0028] In one specific embodiment, the fully automatic robotic arm can be mounted on the second vertical support frame via a sliding groove structure. This allows for impact resistance testing at any height within a certain height range by adjusting the height of the second vertical support frame and the height of the robotic arm itself.

[0029] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0030] 1. The present invention provides an automated testing device for the impact resistance of concrete. The device uses a fully automatic robotic arm to capture, adsorb, and release the metal impact ball, completing the test with one click. This achieves automation, greatly saving testing time. It also eliminates the need for manual reset. The device can achieve automatic reset and automatic testing. The control program ensures that the starting position of each impact is consistent, which can greatly avoid test errors.

[0031] 2. The automated testing device for the impact resistance of concrete provided in this utility model embodiment uses a high-definition camera to take real-time photos of the surface of the test block after impact and compares them with photos of the surface of the test block when the test is completed that are saved in the program. After the comparison results are fed back to the program, the test progress is judged by comparison results. There is no need for manual monitoring of the test progress, which saves manpower.

[0032] 3. The present invention provides an automated testing device for the impact resistance of concrete. The test area of ​​the test bench is equipped with a test block positioning baffle. The concrete test block is placed in the positioning baffle area. When the metal impact ball falls freely, the landing point is kept accurate. At the same time, a barrier is set around the positioning baffle. After the metal impact ball hits the test block, the metal impact ball is within the barrier area. The splashed residue and dust are also within the barrier area, which avoids environmental pollution and makes the position of the metal impact ball controllable.

[0033] 4. The automated testing device for the impact resistance of concrete provided in this embodiment of the utility model uses laser counting, which makes the calculation of the number of impacts of the impact ball more accurate.

[0051] The testing device includes a fully automatic robotic arm 1 and a metal impact ball 5. The fully automatic robotic arm 1 is equipped with a capture chip 3, and the metal impact ball 5 is equipped with a positioning chip 4. The fully automatic robotic arm 1 is electrically connected to the control device through a first control switch 2.

[0052] The capture chip 3, under the action of the control device, captures the position of the positioning chip 4, which in turn feeds back the position of the metal impact ball 5.

[0053] The control device drives the fully automatic robotic arm 1 to move to the metal impact ball 5 and attracts the metal impact ball 5 by electromagnetic means and moves it to the test height, or the control device drives the fully automatic robotic arm 1 to disconnect the electromagnetic means so that the metal impact ball 5 is detached from the fully automatic robotic arm 1 and falls freely.

[0054] This invention employs a fully automated robotic arm, which can complete the capture, adsorption, position and height adjustment, release, free fall, and impact process of the metal impact ball, achieving automation and greatly saving testing time. At the same time, it can achieve automatic reset without the need for manual reset.

[0055] In use, the fully automatic robotic arm 1, after activating the first control switch 2, activates its built-in capture chip 3 to quickly capture the position of the metal impact ball 5, which has a positioning chip 4 installed inside. The control program then activates the capture function. After capture, the fully automatic robotic arm moves to the metal impact ball 5 and connects the electromagnetic device, causing the metal impact ball to adhere to the electromagnetic device of the fully automatic robotic arm. The fully automatic robotic arm then moves the metal impact ball to a preset test height, disconnects the electromagnetic device, and the metal impact ball undergoes free fall until it impacts the surface of the test block. By repeating the above operations, the capture, adsorption, position and height adjustment, release, free fall, and impact processes of the metal impact ball can be automatically completed, thereby achieving the test of the impact resistance performance of the test block.

[0056] The control device in this utility model can be electrically connected to the device components of this application using an existing PLC logic controller, and the fully automatic robotic arm can be an existing industrial robotic arm. The inventive point of this application does not involve improving the control program itself. The inventive point of this application is to connect various devices through existing logic control programs to realize the automation process of impact resistance testing.

[0057] In one specific embodiment, the front end of the fully automatic robotic arm 1 is provided with an electromagnet 6. By energizing and de-energizing the electromagnet, the adsorption and release of the metal impact ball can be achieved.

[0058] In one specific embodiment, the test apparatus further includes a test bench 10, on which a test block positioning structure is provided. The test block positioning structure includes a test block positioning baffle 11 surrounding the test bench 10. The test block positioning baffle 11 surrounds a positioning space forming a top opening, and the positioning space is used to place the test block.

[0059] This invention can fix, position, and limit the test block by setting a test block positioning baffle, which can ensure that the test block will not move during repeated impacts and always keep the metal impact ball hitting the same position, resulting in more accurate test results.

[0060] In one specific embodiment, the test block positioning baffle 11 is further surrounded by a barrier 12. The height of the barrier 12 is higher than that of the test block positioning baffle 11. This can prevent the debris generated during the concrete test from flying everywhere, reduce safety hazards, avoid environmental pollution, and also confine the debris inside the barrier, making it convenient for the subsequent centralized cleaning of concrete fragments.

[0061] In one specific embodiment, the test bench 10 is provided with a first vertical support frame 15 and a second vertical support frame 8. The first vertical support frame 15 and the second vertical support frame 8 are respectively located on both sides of the test block positioning structure. A laser emitter 16 is installed on the side of the first vertical support frame 15 facing the test block positioning structure, and a laser targeting device 17 is installed on the side of the second vertical support frame 8 facing the test block positioning structure. The laser counter is equipped with an independent power supply and a wireless connection module. The laser emitter 16 and the laser targeting device 17 are electrically connected to the digital display screen 19 and the control device through a second control switch 18.

[0062] This invention features a laser emitter. When the metal impact ball falls freely past the laser emitter, the laser target instrument cannot collect the laser light, thus counting once. When the fully automatic robotic arm starts to capture the metal impact ball, the laser counting program stops working and the counting function is not activated. This cycle repeats until the test is completed, achieving automatic counting of the number of impacts. This invention uses a laser counting device; each time the metal ball falls freely past the emitter, it is counted once, eliminating the need for manual counting and achieving automated counting, making the test results more accurate.

[0063] In one specific embodiment, a high-definition camera 20 is also installed on the side of the first vertical support frame 15 facing the test block positioning structure. By setting up a high-definition camera, after the metal impact ball 5 falls freely and impacts the surface of the test piece, the high-definition camera 20 starts its shooting program, capturing real-time photos of the test sample surface and uploading them to the control device. These photos are then compared in real-time with the test surface photos preset in the control device program for when the test is completed. The comparison results are fed back to the control device to determine whether the test is complete and whether the program needs to continue. If the test sample surface photo matches the completed test sample surface photo, the entire test is complete, the program stops, and the corresponding test result is output. If they do not match, the fully automatic robotic arm continues to start, performing the next impact test. This achieves fully automated impact testing without the need for human intervention.

[0064] In one specific embodiment, a vibration sensor 7 is also provided on the test bench 10, and the vibration sensor 7 is electrically connected to the control device. Through the vibration sensor, it can be determined whether the metal impact ball has impacted the test block. If it is determined that it has impacted the test block, then the fully automatic robotic arm can be started to continue to complete the repeated test process of capturing, adsorbing, adjusting the position and height of the metal impact ball, releasing it, and allowing it to fall freely and impact.

[0065] In one specific embodiment, the second vertical support frame 8 has a telescopic structure, which allows the second vertical support frame 8 to be extended or shortened in the vertical direction. The second vertical support frame 8 also has a scale 9, which allows the second vertical support frame to be extended and shortened in the vertical direction, so that the operator can visually observe the release height of the metal impact ball through the scale.

[0066] In one specific embodiment, the test bench 10 in the positioning space is provided with a metal plate 13 that can be flipped downwards, and the automated testing device also includes a recycling device, which includes a waste recycling container 14 disposed below the metal plate 13.

[0067] The metal plate of this invention can be opened or closed freely downwards. After the test is completed, the waste concrete test block can be opened downwards through the metal plate and fall directly into the waste recycling container below, which can achieve environmentally friendly and convenient recycling of the test block.

[0068] In one specific embodiment, the fully automatic robotic arm can be mounted on the second vertical support frame 8 via a sliding groove structure. This allows for impact resistance testing at any height within a certain height range by adjusting the height of the second vertical support frame and the height of the robotic arm itself.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
