[0002] When filling the foundation pit of civil engineering, a large number of engineering transport vehicles are needed. Because most of the engineering transport vehicles pass through the foundation pit, a large number of objects such as stones or nails will sometimes get stuck on the tires, causing damage to the tires. Due to long-term damage, the mass distribution of each part of the whole cannot be very uniform. When the wheels of the engineering transport vehicle rotate at high speed, a dynamic imbalance state will be formed. During engineering transportation, the vehicle will cause wheel shaking and steering wheel vibration while driving. It is necessary to perform dynamic balance detection quickly. If it is not detected in time and an accident occurs, it may cause the suspension of cargo transportation, delay the construction period, and may also cause great property losses. In order to avoid this phenomenon or eliminate this phenomenon that has already occurred, the tires of the engineering transport vehicle need to be dynamically balanced.

[0003] For example, the "A wheel automatic detection device" with publication number CN109975313B includes a machine base, a workbench, an upper guide column, and an upper cylinder. The upper cylinder and the upper guide column are installed at the top center of the machine base. The output end of the upper cylinder is connected to a mobile platform I. Under the guidance of the upper guide column, the upper cylinder controls the mobile platform I to move up and down. A servo motor I is installed at the bottom center of the mobile platform I. The output end of the servo motor I is connected to a rotating table. An adjusting cylinder is arranged at the outer edge of the rotating table. An adjusting guide rail is also arranged on the rotating table corresponding to the position of the adjusting cylinder. A slider is connected to the output end of the adjusting cylinder. The slider is installed on the adjusting guide rail. A visual sensor I is arranged at the bottom of the slider, and a visual sensor II is arranged at the bottom center of the rotating table.

[0004] However, in the prior art, when the existing dynamic balance detection device for the wheel of an engineering transport vehicle tests the tire, a sensor is generally used to perform dynamic balance detection on the tire when it rotates.

When in use, it is first connected to the center of the tire through the clamp 76, and the tire is fixed through the adjustment component 8 and the side of the tire is in contact with the driving wheel 3. When testing, the servo motor 2 drives the driving wheel 3, and the driving wheel 3 pushes the tire to rotate with the rotating rod 1 75 as the center. During the rotation of the tire, the test component 9 will be pushed.

When in use, the rotating rod 2 82 is rotated by the rotating disk 81, and the bevel gear 2 84 is pushed by the bevel gear 1 83, so as to achieve the purpose of pushing the two screw rods 3 85 at the same time. When the screw rod 3 85 rotates, the position of the threaded base 86 will be changed. The threads on the two screw rods 3 85 are in opposite directions because the screw rods 3 85 are symmetrically arranged on the sliding seat 5. Therefore, under the drive of the bevel gear 1 83, the rotation directions of the two screw rods 3 85 are opposite. The opposite thread directions can ensure that the moving directions of the two test assemblies 9 are also opposite, so as to accurately control the position of the test assembly 9. The threaded base 86 threadedly connected to the screw rod 3 85 is used to connect the test assembly 9. The limit rod 87 sleeved on the end of the threaded base 86 is also installed in the sliding seat 5.

[0026] Embodiment 3: According to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the test assembly 9 includes a mounting box 91, one end of the mounting box 91 is connected to the threaded base 86, the number of the mounting boxes 91 is set to two groups, the two groups of mounting boxes 91 are arranged on the same axis, the inner wall of the mounting box 91 is nested with a connecting rod 92, the top of the connecting rod 92 is provided with an indicator box 93, one end of the indicator box 93 is provided with an opening 94, the opening 94 is arranged in an array at one end of the indicator box 93, the bottom end of the connecting rod 92 is provided with a push plate 95, the bottom end of the push plate 95 is provided with a connecting rod 2 96, and the connecting rod 2 96 is nested in At the bottom end of the inner wall of the mounting box 91, the number of connecting rods 96 is set to two groups, and the two groups of connecting rods 96 are arranged on the same axis. A mounting seat 97 is provided at the bottom end of the connecting rod 96, and a spring 98 is provided at the top of the mounting seat 97. The top of the spring 98 is elastically connected to the bottom end of the mounting box 91, and the number of springs 98 is set to two groups, and the two groups of springs 98 are arranged on the same axis at the top of the mounting seat 97. A rotating roller 99 is provided at one end of the mounting seat 97, and the number of rotating rollers 99 is set to two groups, and the two groups of rotating rollers 99 are arranged on the same axis.

[0027] In this embodiment, the installation box 91 is fixedly installed on the threaded base 86. When the threaded base 86 moves, it will drive the installation box 91. The installation box 91 is also symmetrically distributed on the sliding seat 5. A connecting rod 1 92 is arranged inside the installation box 91. The push plate 95 at the bottom of the connecting rod 1 92 is connected to the mounting seat 2 97 through the connecting rod 2 96. The rotating roller 99 is installed on the side of the mounting seat 2 97. When testing the tire, the rotating roller 99 overlaps the edge of the tire. When the tire rotates, if the shape of the tire is irregular, the mounting seat 2 97 will be pushed by the rotating roller 99. A spring 98 is connected between the mounting seat 2 97 and the connecting rod 1 92. When the mounting seat 2 97 is pushed, the spring 98 will be compressed, and in this process, the connecting rod 2 96 will also push the push plate 95. The push plate 95 pushes up the indicator box 93 through the connecting rod 92. A plurality of openings 94 are provided inside the indicator box 93. Under normal circumstances, the infrared laser emitted by the infrared laser transceiver 6 will normally pass through the opening 94 and be emitted to the receiving plate. However, if the push plate 95 changes the height of the indicator box 93, it will directly affect the continuity of the emitted infrared laser line. By visually converting the circular runout difference on both sides of the tire, the dynamic balance of the tire can be detected in real time.

[0028] The use method and working principle of the device: when testing a tire, first determine the position of the tire through the positioning assembly 7, fix the center position of the tire with the clamp 76, then change the horizontal position of the rotating rod 75 by rotating the screw rod 1 71, and change the height of the rotating rod 1 75 by rotating the screw rod 2 79. The tire can be accurately fixed in a fixed position by using the combination, and the existence of the slide groove 77 will not affect the horizontal movement of the mounting block 74; After the position of the tire is determined, the rotating plate 81 is used to rotate the rotating rod 82, and the bevel gear 83 at the end of the rotating rod 82 simultaneously pushes the two bevel gears 84 to simultaneously push the two screw rods 85. The rotation directions and threads of the two screw rods 85 are opposite. During the rotation, the position of the installation box 91 is adjusted through the threaded base 86, so that the rotating roller 99 overlaps the edge of the tire. After the state of the tire is fully determined, the servo motor 2 is started to drive the driving wheel 3, and the driving wheel 3 is used to push the tire to rotate with the rotating rod 1 75 as the center. During the rotation of the tire, the infrared laser emitted by the infrared laser transceiver 6 will normally pass through the opening 94 and shoot onto the receiving plate. If the shape of the tire is irregular, the mounting seat 2 97 will be pushed by the rotating roller 99, and the mounting seat 2 97 will push the push plate 95 through the connecting rod 2 96 to change the height of the indicator box 93. At this time, the indicator box 93 will directly affect the continuous state of the emitted infrared laser line. By visually converting the circular runout difference on both sides of the tire, the dynamic balance of the tire can be detected in real time.
