DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0019] A rebound test device 1, such as Figure 1 As shown, it includes a mechanical arm assembly 3, an operating arm 4 and a rebound test assembly 5, the operating arm 4 is arranged at the end of the mechanical arm assembly 3, the rebound test assembly 5 is arranged at the end of the operating arm 4, and the rebound test assembly 5 is provided with an angle sensor 52 and / or a force sensor 51.

[0020] The rebound test assembly is used to test the rebound value of the target part. The mechanical arm assembly 3 is used to control the rebound test assembly to enter the target position through the operating arm 4. It can enter the position that is difficult to reach manually to test the target part, thereby improving the test efficiency and ensuring the accuracy and repeatability of the test. The angle sensor is used to detect the angle of the rebound test assembly, and the force sensor 5 is used to detect the pressing force.

[0021] Among them, a movable joint 46 is provided at the end of the operating arm 4, and the rebound test assembly 5 is detachably mounted on the movable joint 46. The rebound test assembly 5 can be mounted on the movable joint 46 by bolts or stoppers, and realize electrical connection. The rebound test assembly 5 includes two parts: a weight and a spring hammer. The test principle is to use a spring to drive the weight in the test head, and to bounce the concrete surface through the spring rod and force transmission rod, and measure the distance that the weight is rebounded back, and use the rebound value as the ratio of the rebound distance to the initial length of the spring as a strength-related indicator to estimate the concrete strength. The spring-driven spring hammer generates a restoring force of instantaneous elastic deformation by bouncing the spring rod on the concrete surface, and the spring hammer drives the pointer to rebound and indicates the rebound distance - the rebound value. The rebound test assembly 5 is a commercially available product, and this application will not repeat it.

[0022] The operating arm 4 is provided with any of the following components or their combination: a self-sensing probe 42, a displacement sensor 45, an identification module 44, and an electronic gyroscope 41. The self-sensing probe 42 is used to automatically identify the type and size of target pieces such as concrete specimens, so as to determine the route of the operation and monitor the construction process in real time. The displacement sensor 45 is used to detect the displacement of the operating arm 4; the electronic gyroscope 41 is also called an electronic gyroscope, which is used to detect the posture of the operating arm 4; the identification module 44 is implemented through image recognition technology to improve the degree of automation of the test. More specifically, the electronic gyroscope 41 is arranged on the upper side of the operating arm 4. The detection of each position variable, force variable and rebound value during the rebound test is realized, which is conducive to the precise positioning and precise control of the detection process. These sensors can monitor the contact between the mechanical arm and the concrete specimen in real time and transmit the data to the control module 24.

[0023] The robot arm assembly 3 includes a plurality of intermediate connecting rods 31 and joints 32, and the intermediate connecting rods 31 and the joints are connected in sequence. Figure 1 Only some of the intermediate connecting rods 31 and the joints 32 are shown, and more intermediate connecting rods 32 can actually be designed according to the working conditions.

[0024] Figure 1An operation platform is also shown, the mechanical arm assembly 3 is mounted on the operation platform 2, and the servo 22 of the mechanical arm assembly 3 is mounted in the operation platform 2. A power supply 21, a display 23 and a control module 24 are also provided in the operation platform, the power supply 21 is electrically connected to the servo 22, the display 23 and the control module 24, and the control module 24 is connected to the angle sensor 52, the force sensor 51, the display 23 and the servo 22.

[0025] The movement and force of the robot arm assembly 3 can be precisely controlled to ensure the accuracy and repeatability of the test. Driven by a high-precision servo motor, it can achieve micron-level motion accuracy. The multi-joint setting can achieve more flexible and accurate testing.

[0026] The control module 24 is used to receive data from the sensor, process and analyze the data; display the results to the operator through the display; and is also used to accurately control the robot arm assembly. The control module 24 can be implemented by a computer or an embedded system. The angle, pressure, and position of the rebound test assembly 5, as well as the running direction of the electronic gyroscope, can be changed at any time. Thus, real-time and accurate testing can be achieved.

[0027] The control console is used to fix and support the mechanical arm assembly, the operating arm and the rebound test assembly 5, and can be fixed with a high-strength steel or aluminum alloy base, which can withstand large torques and impacts during the test.

[0028] The utility model is equipped with a gyroscope inside, which can self-position, and the rebound angle can be automatically adjusted according to the specific situation; the mechanical arm component 3 can replace manual measurement operations in places where manual operation is inconvenient, such as the outer arm of a bridge; it can automatically measure, display, calculate, and independently correct angles; the identification module is equipped with a camera device, which can observe the construction in real time and the actual situation on site; the display console can better operate and control the construction work.

[0029] The utility model combines advanced mechanical arm technology and sensor technology to automatically and accurately complete the rebound test. The main advantages of the rebound tester of the utility model are its automation and precision. By precisely controlling the movement and strength of the mechanical arm, the accuracy and repeatability of the test are ensured. In addition, through the connection with the computer, the test data can be transmitted and analyzed in real time, which greatly improves the test efficiency. It can cope with some less convenient environments. For example, when performing rebound tests in large building structures such as bridges, manual testing may encounter difficulties due to location and space limitations. The utility model can easily complete these test tasks through its flexible movement ability and the characteristics of adapting to various complex environments.

[0030] The research background of this utility model is based on the demand for the safety and reliability of building structures in relatively inconvenient environments such as bridges. By improving the automation and accuracy of rebound testing, the quality and safety of these structures can be better guaranteed. This application will provide the engineering community with a more effective and reliable rebound testing method, which is very necessary.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
