Description

Technical Field

[0001] This invention relates to the field of wheel dynamic balancing testing technology, specifically to a rapid dynamic balancing testing device for the wheels of an engineering transport vehicle used in foundation pit construction. Background Technology

[0002] During the filling of foundation pits in civil engineering projects, a large number of engineering transport vehicles are required. As most of these vehicles drive over the pit, objects such as stones or nails sometimes get stuck in the tires, causing damage. Over time, this damage makes it impossible for the mass distribution of the entire structure to be very uniform. When the wheels of the engineering transport vehicles rotate at high speed, a dynamic imbalance will occur. During transportation, this will cause the wheels to shake and the steering wheel to vibrate. A dynamic balance test needs to be performed quickly. If the test is not performed in time, accidents may occur, which may cause the suspension of cargo transportation, delay the construction period, and may also cause great property damage. To avoid this phenomenon or to eliminate the phenomenon that has already occurred, the tires of engineering transport vehicles need to be dynamically balanced.

[0003] For example, the "Automatic Wheel Detection Device" with publication number CN109975313B includes a base, a worktable, an upper guide column, and an upper cylinder. The upper cylinder and the upper guide column are installed at the top center of the base. The output end of the upper cylinder is connected to a moving platform I. Under the guidance of the upper guide column, the upper cylinder controls the moving platform I to move up and down. A servo motor I is installed at the bottom center of the moving platform I. The output end of the servo motor I is connected to a rotary table. An adjusting cylinder is set on the outer edge of the rotary table. An adjusting guide rail is also set on the rotary 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 vision sensor I is set at the bottom of the slider. A vision sensor II is set at the bottom center of the rotary table.

[0004] However, in the existing technology, the existing dynamic balancing testing devices for the wheels of engineering transport vehicles generally use sensors to perform dynamic balancing tests on the tires as they rotate. These devices typically employ a large number of sensor-like electronic components to position the tires and adjust them according to the tire diameter. This process is subject to electromagnetic interference, which affects the accuracy of the test data. Furthermore, the accuracy of the sensors is also affected by their lifespan. Sensors used for a long time will experience a decline in accuracy due to aging, requiring replacement and resulting in high operating costs. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, by setting up a positioning component and utilizing the rotational effect of screw one and screw two, while simultaneously setting up the cooperation between the slide rod, mounting block, and slide groove, the horizontal and vertical positions of the mounting block are adjusted twice to achieve the positioning adjustment effect for tires of different diameters. This ensures that one end of the tire requiring dynamic balancing is in contact with the drive wheel. Operators can make real-time adjustments before dynamic balancing according to tires of different diameters, avoiding the problem of the sensor being affected by electromagnetic interference, which affects the accuracy of the test results. At the same time, it solves the problem that the accuracy of the sensor will decrease due to aging, requiring the replacement of the sensor and resulting in high operating costs.

[0021] 2. In this invention, by setting an adjustment component, utilizing the meshing linkage between bevel gear one and two sets of bevel gear two, and simultaneously cooperating with the positioning component to adjust the positioning effect of tires of different diameters, the test component is adjusted in real time. The contact surface between the bottom of the test component and tires of different diameters is adjusted. While making adaptive adjustments to tires of different diameters, the operator can also make secondary adjustments to the contact position between the test component and the tire to be tested, further ensuring the accuracy of dynamic balancing tests on tires of different diameters and making it applicable to tires of different diameters, thus ensuring the accuracy when performing dynamic balancing on tires of different diameters.

[0022] 3. In this invention, by setting up a test component, the force exerted when the tire exhibits a circular runout difference on both sides is utilized. Through the linkage between the spring, connecting rod two, and push plate, and in conjunction with the effect between the infrared laser transceiver and the indicator box, the circular runout difference on both sides of the tire is visualized by observing the continuous state of the infrared laser line emitted by the infrared laser transceiver. This allows operators to make real-time judgments on the tire's dynamic balance during testing. The structure is simple and has low operating costs, reducing the use and maintenance costs of the device for tire dynamic balance testing. At the same time, it is less affected by external force factors and provides a more intuitive view of the dynamic balance test results. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown: A dynamic balancing rapid detection device for the wheels of an engineering transport vehicle used for foundation pit construction includes a mounting base 1, a servo motor 2 is provided on one side of the top of the mounting base 1, a drive wheel 3 is provided at one end of the servo motor 2, an electric slide rail 4 is provided at one end of the mounting base 1, a sliding seat 5 is nested in the inner wall of the electric slide rail 4, and an infrared laser transceiver 6 is provided at the top of the sliding seat 5.

[0034] It also includes a positioning component 7. The positioning component 7 is provided on one side of the electric slide rail 4. The positioning component 7 is used to position the tire that needs to be dynamically balanced. The positioning component 7 includes a screw 71. The screw 71 is provided at one end of the electric slide rail 4. A screw ring 72 is sleeved on the outer surface of the screw 71. A slide rod 73 is provided at the top of the screw ring 72. An installation block 74 is sleeved on the outer surface of the slide rod 73. A rotating rod 75 is provided at one end of the installation block 74. A clamp 76 is provided on the outer surface of the rotating rod 75.

[0035] Adjustment component 8 is provided on the inner wall of the sliding seat 5. Adjustment component 8 is used to adjust the test component 9 according to the diameter of the tire to be dynamically balanced as needed.

[0036] Test component 9 is provided on the adjustment component 8. Test component 9 is used to perform dynamic balance testing on the tire.

[0037] The outer surface of the mounting block 74 is fitted with a sliding groove 77, and a second threaded ring 78 is provided at one end of the sliding groove 77. A second threaded rod 79 is fitted on the inner wall of the second threaded ring 78, and the second threaded rod 79 is located at one end of the electric slide rail 4.

[0038] In this embodiment, the mounting base 1 is fixedly installed on the side of the electric slide rail 4, and the servo motor 2 is fixed on the mounting base 1. The output end of the servo motor 2 is connected to the drive wheel 3. In use, the clamp 76 is first connected to the center of the tire, and the tire is fixed by the adjustment component 8 so that the side of the tire contacts the drive wheel 3. During the test, the servo motor 2 drives the drive wheel 3, and the drive wheel 3 pushes the tire to rotate around the rotating rod 75. During the rotation of the tire, the test component 9 is pushed. During this process, the infrared laser transceiver 6 set on the sliding seat 5 is always emitting infrared laser. The movement of the test component 9 will block the emission path of the infrared laser. By observing the continuous state of the infrared laser line emitted by the infrared laser transceiver 6, the circular jump difference on both sides of the tire is visualized and converted to determine whether the tire is in a uniform state.

[0039] The positioning component 7 is installed on the side of the electric slide rail 4, the clamp 76 is installed at the end of the rotating rod 75, and the other end of the rotating rod 75 is fixedly connected to one side of the mounting block 74. The mounting block 74 is sleeved on the slide rod 73. When determining the tire position, the position of the rotating rod 75 is mainly changed by rotating the screw 71. When the screw 71 rotates, it will change the position of the threaded ring 72 through the thread, thereby changing the horizontal position of the slide rod 73.

[0040] The sliding groove 77 fitted on the outer wall of the mounting block 74 is fixedly connected to the screw ring 78. When it is necessary to adjust the height of the rotating rod 75, the height of the sliding groove 77 is changed by rotating the screw 79, thereby achieving the purpose of adjusting the height of the rotating rod 75. The sliding groove 77 will not affect the horizontal movement of the mounting block 74.

[0041] Example 2: According to Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the adjusting assembly 8 includes a rotating disk 81, which is disposed at the top of the inner wall of the sliding seat 5. A rotating rod 82 is disposed at one end of the rotating disk 81, and a bevel gear 83 is disposed at one end of the rotating rod 82. A bevel gear 84 is meshed on one side of the bevel gear 83. The bevel gear 84 is disposed at the top of the inner wall of the sliding seat 5. There are two sets of bevel gears 84, which are arranged opposite to each other at the top of the inner wall of the sliding seat 5. A screw 85 is disposed at one end of the bevel gear 84, and one end of the screw 85 is disposed on the inner wall of the sliding seat 5. A threaded base 86 is sleeved on the outer surface of the screw 85, and a limiting rod 87 is sleeved on one end of the threaded base 86. One end of the limiting rod 87 is disposed on the inner wall of the sliding seat 5.

[0042] In this embodiment, bevel gear 83 and bevel gear 84 are meshed at the end of rotating rod 82. During use, rotating rod 82 is rotated by rotating disk 81, and bevel gear 83 pushes bevel gear 84 to simultaneously push two screws 85. When screws 85 rotate, they change the position of threaded base 86. The threads on the two screws 85 are in opposite directions. Since screws 85 are symmetrically arranged on sliding seat 5, under the drive of bevel gear 83, the rotation directions of the two screws 85 are opposite. The opposite thread directions ensure that the movement directions of the two test components 9 are also opposite, so as to accurately control the position of the test components 9.

[0043] The threaded base 86 connected to the screw 3 85 is used to connect the test assembly 9. The limiting rod 87, which is sleeved at the end of the threaded base 86, is also installed in the sliding seat 5. When the screw 3 85 drives the threaded base 86, it can prevent the threaded base 86 from rotating.

[0044] Example 3: According to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the test component 9 includes a mounting box 91, one end of which is connected to a threaded base 86. Two sets of mounting boxes 91 are arranged along the same axis. A connecting rod 92 is nested within the inner wall of the mounting box 91. An indicator box 93 is located at the top of the connecting rod 92, with an opening 94 extending through one end of the indicator box 93. The openings 94 are arranged in an array at one end of the indicator box 93. A push plate 95 is located at the bottom of the connecting rod 92, and a connecting rod 96 is located at the bottom of the push plate 95. The connecting rod 96 is nested within the mounting box 91. At the bottom of the inner wall of the mounting box 91, there are two sets of connecting rods 96, which are arranged on the same axis. The bottom of the connecting rods 96 is provided with a mounting seat 97, and the top of the mounting seat 97 is provided with a spring 98. The top of the spring 98 is elastically connected to the bottom of the mounting box 91. There are two sets of springs 98, which are arranged on the same axis at the top of the mounting seat 97. One end of the mounting seat 97 is provided with a rotating roller 99, which is also provided with two sets of rotating rollers 99, which are arranged on the same axis.

[0045] In this embodiment, the mounting box 91 is fixedly mounted on the threaded base 86. When the threaded base 86 moves, it will drive the mounting box 91. The mounting box 91 is also symmetrically distributed on the sliding seat 5. A connecting rod 92 is provided inside the mounting box 91. The push plate 95 at the bottom of the connecting rod 92 is connected to the mounting seat 97 via the connecting rod 96. The rotating roller 99 is installed on the side of the mounting seat 97. When testing the tire, the rotating roller 99 overlaps the edge of the tire. When the tire rotates, if the tire shape is irregular, it will push the mounting seat 97 via the rotating roller 99. A spring 98 is connected between the mounting seat 97 and the connecting rod 92. When the mounting seat 97 is pushed, the spring 98 will be compressed. In this process, the connecting rod 96 will also push the push plate 95.

[0046] The push plate 95 pushes the indicator box 93 upward through the connecting rod 92. The inside of the indicator box 93 has multiple openings 94. Under normal circumstances, the infrared laser emitted by the infrared laser transceiver 6 will pass through the openings 94 and be emitted onto 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 visualizing the difference in circular runout on both sides of the tire, the dynamic balance of the tire can be detected in real time.

[0047] The method of use and working principle of this device: When inspecting a tire, the position of the tire is first determined by the positioning component 7, and the clamp 76 is fixed to the center position of the tire. Then, the horizontal position of the rotating rod 75 is changed by rotating the screw 71, and the height of the rotating rod 75 is changed by rotating the screw 79. By using these methods together, the tire can be accurately fixed in a fixed position. The presence of the slide groove 77 will not affect the horizontal movement of the mounting block 74.

[0048] After determining the position of the tire, the rotating rod 82 is rotated by rotating disk 81. The bevel gear 83 at the end of the rotating rod 82 simultaneously pushes the two bevel gears 84, thereby simultaneously pushing the two screws 85. The rotation direction and the threads of the two screws 85 are opposite. During its rotation, the position of the mounting box 91 is adjusted by the threaded base 86, so that the rotating roller 99 is attached to the edge of the tire.

[0049] After the tire's condition is fully determined, the servo motor 2 is started to drive the drive wheel 3. The drive wheel 3 pushes the tire to rotate around the rotating rod 75. During the tire's rotation, the infrared laser emitted by the infrared laser transceiver 6 will pass through the opening 94 and be projected onto the receiving plate. If the tire's shape is irregular, the rotating roller 99 will push the mounting base 97. The mounting base 97 will push the push plate 95 through the connecting rod 96, changing the height of the indicator box 93. At this time, the indicator box 93 will directly affect the continuity of the emitted infrared laser line. By visualizing the difference in circular runout on both sides of the tire, the dynamic balance of the tire can be detected in real time.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
