[0019] 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.
[0020] Please see Figures 1-6 This utility model provides a technical solution: A crane boom deformation inspection tool includes a mounting base 1, an adjustment component 2 installed inside the mounting base 1, two sets of rectangular blocks 3 connected to the adjustment component 2, a deformation detection component 4 installed between the two sets of rectangular blocks 3, a support component 10 installed at the bottom of the mounting base 1, an alarm 5 fixedly installed at the top of the mounting base 1, the alarm 5 being electrically connected to the deformation detection component 4, and several sets of mounting plates 7 evenly fixedly installed on the left and right sides of the top of the mounting base 1, an adjustment component 6 installed between the several sets of mounting plates 7, and a rolling component 9 connected to the adjustment component 6.
[0021] Furthermore, the support assembly 10 includes support columns 101. Two sets of support columns 101 are fixedly installed at the front and rear ends of the bottom of the mounting base 1. Rollers 102 are rotatably connected to the bottom of both sets of mounting bases 1. When it is necessary to detect the deformation of the boom, the rollers 102 at the bottom of the mounting base 1 are first placed on the top of the boom.
[0022] Furthermore, the adjustment component 6 includes a dual-head motor 61, which is fixed between two sets of mounting plates 7 near the top center of the mounting base 1. The two output ends of the dual-head motor 61 pass through the mounting plates 7 and are fixedly connected to threaded rods 64. The two sets of threaded rods 64 are rotatably connected to the mounting plates 7 located at the outer ends of the mounting base 1. The top of the mounting base 1 between the two sets of mounting plates 7 on the left and right sides of the dual-head motor 61 is provided with a sliding groove 63. The inner walls of the two sets of sliding grooves 63 are slidably connected to strip columns 62. The two sets of strip columns 62 are threadedly connected to the two sets of threaded rods 64. The bottom of the strip columns 62 is connected to the rolling component 9. The output ends of the dual-head motor 61 drive the threaded rods 64 to rotate, so that the strip columns 62 drive the rolling component 9 to move along the sliding grooves 63, thereby allowing the rolling component 9 to clamp the outer walls of the machine arm of different sizes.
[0023] Furthermore, the rolling assembly 9 includes a single-head motor 92. Two sets of single-head motors 92 are fixedly connected to the bottom of the strip column 62. A groove is opened at the lower end of the strip column 62, and the single-head motor 92 is installed inside the groove. A guide wheel 91 is fixedly installed at the output end of the single-head motor 92. During the movement of the strip column 62, when the guide wheel 91 contacts the outer wall of the machine arm, the output end of the single-head motor 92 drives the guide wheel 91 to rotate, thereby driving the entire mounting base 1 to move along the machine arm, so that the deformation detection assembly 4 automatically starts detection.
[0024] Furthermore, the adjustment component 2 includes a rectangular cavity 24, which is located inside the mounting base 1. Rectangular grooves 25 are provided on both the front and rear sides of the top of the mounting base 1, communicating with the rectangular cavity 24. Threaded rods 21 are rotatably connected to the inner walls of both the front and rear sides of the rectangular cavity 24. One end of each threaded rod 21 extends to the outside of the mounting base 1, and the end of the threaded rod 21 located outside the mounting base 1 is rotatably connected to a rectangular block 3. Guide rods 22 are fixedly connected to the side walls of both rectangular blocks 3, and the guide rods 22 are slidably connected to the inside of the rectangular cavity 24. Turntables 23 are rotatably connected to the inner walls of the two rectangular grooves 25, and the two turntables 23 are threadedly connected to the two threaded rods 21 respectively. Rotating the two turntables 23 causes the two threaded rods 21 to extend the rectangular blocks 3 to the front and rear sides of the mounting base 1 to a certain distance, facilitating the deformation detection component 4 to detect different lengths of the machine arm.
[0025] Furthermore, the deformation detection component 4 includes guide posts 42, with two sets of guide posts 42 slidably connected to two sets of rectangular blocks 3 respectively. A tray 45 is fixedly installed on the top of each set of guide posts 42. A spring 46 is fixedly installed between the bottom of each set of trays 45 and the top of the rectangular blocks 3, and the spring 46 is sleeved on the outside of the guide posts 42. A tension sensor 41 and a top seat 44 are fixedly installed on the top of each set of trays 45 respectively. A spring rod 43 is fixedly installed between the tension sensor 41 and the top seat 44. A spherical block is installed at the bottom of the guide posts 42. After the two sets of rectangular blocks 3 are expanded to a certain distance, the mounting base 1 is placed on the machine arm, so that the bottoms of the two sets of guide posts 42 are positioned one in front of the other. As the guide wheel 91 moves the mounting base 1 along the top of the boom, a certain span exists between the two sets of guide columns 42. When the boom bends, a height difference will occur between the front and rear sets of guide columns 42. When a height difference occurs, the front set of guide columns 42 will pull the elastic rod 43 through the top seat 44, causing the elastic rod 43 to generate tension. The tension sensor 41 detects this tension. The greater the height difference between the front and rear guide columns 42, the greater the tension on the elastic rod 43. Before detection, an upper limit value can be set through the tension sensor 41. When the tension on the elastic rod 43 exceeds the upper limit, it indicates that the height difference is relatively large and there is a relatively large deformation.
[0026] Furthermore, the elastic rod 43 has the function of freely extending and shortening. The extension and shortening of the rectangular block 3 will cause the elastic rod 43 to extend and shorten accordingly through the guide post 42.
[0027] Furthermore, the alarm 5 is electrically connected to the tension sensor 41. When the tension on the spring rod 43 exceeds the upper limit, the tension sensor 41 transmits a signal to the alarm 5, causing the alarm 5 to emit a red light alarm. If the tension is below the upper limit during movement, it indicates that the height difference is within the safe range and the deformation is relatively small, so the alarm 5 will not sound. This is used to check the degree of deformation of the crane boom. Compared with traditional detection methods, the detection is more convenient, effectively improving detection efficiency and reducing usage limitations.
[0028] Furthermore, a control device 8 is fixedly installed on the side wall of the mounting base 1. The control device 8 is electrically connected to the dual-head motor 61 and is a PLC controller.
[0029] Furthermore, two sets of handles 11 are fixedly installed on the top of the mounting base 1. The outer wall of the handles 11 is provided with anti-slip texture. The handles 11 are designed to facilitate placing the mounting base 1 on the top of the machine arm.
[0030] Working principle: Based on the length of the boom, the spacing between the two sets of rectangular blocks 3 is first adjusted by adjusting component 1 2 to increase the detection span of the deformation detection component 4. Then, the support component 10 under the mounting base 1 is brought into contact with the top of the boom to be tested. Next, the rolling component 9 is brought into contact with the outer wall of the boom by adjusting component 2 6. Finally, the rolling component 9 is controlled to drive the mounting base 1 to move along the boom. When the boom bends, the deformation detection component 4 will detect it in time and sound an alarm through the alarm 5.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
