Description

Technical Field

[0001] This invention relates to the field of vibration testing technology, specifically to a vibration testing instrument for static balance testing of concrete leveling machine rollers. Background Technology

[0002] The pressure roller is an important component of a concrete screed, and its quality is related to the flatness of the concrete after paving. Therefore, quality control of the pressure roller is very important in the production process of a concrete screed.

[0003] Specifically, when a concrete screed is working, its pressure rollers are rotating at high speed. If the pressure rollers are out of sync, it will cause abnormal vibrations in the concrete screed during operation. These vibrations will directly affect the final result of the concrete paving.

[0004] The existing vibration testing of pressure rollers generally uses static balance testing. However, the specifications of pressure rollers of different models of concrete leveling machines vary. When using static balance testing, it is necessary to adjust the pressure rollers of different specifications before testing, which makes the whole testing cycle long and the operation difficult.

[0017] As a further embodiment of the present invention: the pushing structure includes a base plate rotatably connected to the pulley, and two sliding grooves are symmetrically arranged on the base plate. A slider fixedly connected to the second telescopic shaft is slidably installed in the sliding groove.

[0018] The pushing structure also includes a follower plate connected to the hysteresis sleeve. A hollow groove is formed in the follower plate, and an inclined surface that abuts against the pulley is provided on the side wall of the hollow groove.

[0020] The guide plate is fixedly connected to the support device, and the double-headed cylinder on the support device is connected to the traction frame.

[0021] As a further aspect of the present invention, it also includes:

[0022] A frame, on which side frames are provided;

[0023] The universal connector is connected to the side frame. A rotating sleeve is rotatably mounted on the universal connector. The rotating sleeve is circumferentially arranged with multiple sets of rubber abutment parts.

[0024] The telescopic ring is coaxial with the rotating sleeve, and the telescopic ring is connected to the rubber abutment through a guide structure.

[0025] As a further embodiment of the present invention: a through groove is formed on the side frame, and the universal connector includes a rotating frame rotatably installed in the through groove, a rotating plate is rotatably installed in the rotating frame, and the rotation center of the rotating frame is perpendicular to the rotation center of the rotating plate.

[0026] The drive device, which is fixedly mounted on the rotating plate, is connected to the rotating sleeve.

[0027] As a further embodiment of the present invention: the guiding structure includes through holes arranged circumferentially at equal intervals on the side wall of the rotating sleeve, and side plates are provided on both sides of the through holes;

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] By setting up a traction component, when limiting the concrete screed rollers of different diameters, the four sets of No. 2 rollers can be circumferentially and evenly spaced against the concrete screed rollers, thus ensuring stable limiting of the concrete screed rollers and effectively preventing the concrete screed rollers from slipping off between the four sets of No. 2 rollers when the diameter of the concrete screed rollers changes, thereby improving the stability and safety of the testing process.

[0033] By setting up energy storage components and a pushing structure, the elastic force of the cylindrical spring can automatically match the diameter of the concrete leveling machine roller. On the one hand, this ensures a good limiting effect on the concrete leveling machine roller, preventing it from separating from the No. 2 roller during rotation. On the other hand, it fully releases the swaying of the concrete leveling machine roller during rotation, making it easier to detect and improving the accuracy of the detection results.

[0034] By incorporating a rubber abutment, a guiding structure, a rotating sleeve, and a telescopic ring, the rubber abutment can clamp the concrete screed roller while simultaneously causing the roller to tend to move further into the rotating sleeve. This ensures consistent contact force between the rotating sleeve and the concrete screed roller in both the circumferential and horizontal directions, preventing the roller from detaching from the rubber abutment when it rotates and oscillates, thus improving the stability of the connection between them.

[0045] 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.

[0046] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0047] Please see Figures 6-9 In this embodiment of the invention, the vibration detector for static balance testing of the concrete screed roller includes: a guide component, an energy storage component, a traction component, and a pushing structure. This allows the elastic force of the cylindrical spring 22 to automatically match the diameter of the concrete screed roller. On one hand, this ensures a good limiting effect on the concrete screed roller, preventing it from separating from the second roller 24 during rotation. On the other hand, it fully releases the swaying of the concrete screed roller during rotation, making it easier to detect and improving the accuracy of the test results. Specifically, as follows:

[0048] The guide is provided in two sets, and each set of guides is provided with two No. 2 rollers 24. The guide includes two parallel guide plates 20. Each guide plate 20 is symmetrically provided with two No. 2 inclined grooves 2001. Specifically, the No. 2 inclined grooves 2001 are inclined at 45°.

[0049] The energy storage component is connected to the second roller 24. The energy storage component has a built-in cylindrical spring 22, and a pulley 28 is provided at the end of the energy storage component away from the second roller 24. The energy storage component includes two hysteresis sleeves 21 disposed between the two guide plates 20. The cylindrical spring 22 is disposed in the hysteresis sleeve 21, and a first telescopic shaft 23 and a second telescopic shaft 25 connected to the cylindrical spring 22 are slidably installed at both ends of the hysteresis sleeve 21, respectively. The first telescopic shaft 23 is rotatably connected to the second roller 24. In detail, the above-mentioned energy storage component is provided in four sets, which are respectively connected to four second rollers 24.

[0050] The traction assembly is connected to the hysteresis sleeve 21. When the traction assembly drives the energy storage assembly to move toward the concrete leveling machine roller, the hysteresis sleeve 21 can slide along the second inclined groove 2001. The traction assembly includes a connecting plate 19 fixedly connected to the hysteresis sleeve 21. The connecting plate 19 is provided with a second inclined block 1901 that can slide in the second inclined groove 2001.

[0051] The traction assembly also includes a traction frame 17 parallel to the guide plate 20. The traction frame 17 is provided with a hysteresis groove 1701. The second groove wheel 18, which is rotatably connected to the second inclined block 1901, can roll in the hysteresis groove 1701. In this embodiment, there are two sets of traction frames 17, and the two sets of traction frames 17 are connected by a double-headed cylinder 16.

[0052] In the initial state, the two sets of traction frames 17 are far apart from each other. At this time, the axes of the four sets of No. 2 rollers 24 are respectively located in a plane inclined at 45° in the radial direction of the concrete leveling machine roller, and the distance between the axes of the four sets of No. 2 rollers 24 and the concrete leveling machine roller is the same. When the double-headed cylinder 16 is activated and drives the two sets of traction frames 17 to move closer to each other, the traction frame 17, through the cooperation of the No. 2 grooved wheel 18 and the hysteresis groove 1701, can drive the hysteresis sleeves 21 located on both sides of the concrete leveling machine roller to move towards the concrete leveling machine roller. At the same time, under the guidance of the No. 2 inclined block 1901 and the No. 2 inclined groove 2001, the two hysteresis sleeves 21 located on the same side of the concrete leveling machine roller will also move towards the concrete leveling machine roller. The hysteresis sleeves 21 located on both sides of the concrete screed roller can move towards the concrete screed roller synchronously, and the two hysteresis sleeves 21 on the same side of the concrete screed roller can also move towards each other. That is, the hysteresis sleeves 21 have a horizontal displacement and a vertical displacement when they move. Since the second inclined groove 2001 is at 45°, the hysteresis sleeves 21 can move towards the concrete screed roller along the 45° inclined plane in the radial direction of the concrete screed roller. This allows the second roller 24 to be evenly distributed on the concrete screed roller when it moves to fit with the concrete screed roller, thus achieving a limiting effect on the concrete screed roller.

[0053] Furthermore, due to the differences in the specifications of the concrete screed rollers, when dealing with concrete screed rollers of different diameters, it is only necessary to ensure that the No. 2 roller 24 is in contact with the concrete screed roller to ensure that the No. 2 roller 24 is evenly distributed on the circumferential surface of the concrete screed roller. This allows the device to limit the movement of concrete screed rollers of different diameters and prevents the concrete screed roller from slipping off between the four sets of No. 2 rollers 24 due to swinging during testing.

[0054] With the above settings, when limiting the concrete screed rollers of different diameters, the four sets of No. 2 rollers 24 can be circumferentially and equally spaced against the concrete screed rollers, thus ensuring stable limiting of the concrete screed rollers. This effectively prevents the concrete screed rollers from slipping off between the four sets of No. 2 rollers 24 when the diameter of the concrete screed rollers changes, improving the stability and safety of the testing process.

[0055] It should be noted that when the concrete screed roller is limited, the rotation of the concrete screed roller is controlled. If the center of gravity of the concrete screed roller is eccentric, it will cause the concrete screed roller to wobble. At this time, the distance detection device (not shown in the figure) can detect the distance between it and the concrete screed roller. By detecting the distance, the swing amplitude of the concrete screed roller can be measured to obtain the vibration amplitude of the concrete screed roller.

[0056] Please see Figure 6 , Figure 7 , Figure 9 The pushing structure is connected to the second telescopic shaft 25. The pushing structure cooperates with the pulley 28 and can release one end of the cylindrical spring 22 when the energy storage component moves toward the concrete leveling machine roller.

[0057] The pushing structure includes a base plate 27 rotatably connected to the pulley 28. Two sliding grooves 2701 are symmetrically arranged on the base plate 27. A slider 26 fixedly connected to the second telescopic shaft 25 is slidably installed in the sliding groove 2701.

[0058] The pushing structure also includes a follower plate 29 connected to the hysteresis sleeve 21. A hollow groove is formed in the follower plate 29, and an inclined surface 2901 that abuts against the pulley 28 is provided on the side wall of the hollow groove.

[0059] When the four sets of No. 2 rollers 24 are in a state of being far apart from each other, the vertical distance between the two hysteresis sleeves 21 on the same side of the concrete leveling machine roller is the largest. This makes the contact position of the two sets of follower plates 29 and pulleys 28 closer to the side of the hysteresis sleeve 21. That is, the greater the distance that the No. 2 telescopic shaft 25 extends into the hysteresis sleeve 21, the greater the degree of compression of the column spring 22. If there is a concrete leveling machine roller whose circumferential surface is just in contact with the four sets of No. 2 rollers 24, the column spring 22 can provide a greater limiting capacity when it rotates.

[0060] If the diameter of the concrete screed roller is small, four sets of No. 2 rollers 24 need to move toward the concrete screed roller. At this time, the two hysteresis sleeves 21 on the same side of the concrete screed roller will also move closer to each other. When the two hysteresis sleeves 21 on the same side of the concrete screed roller move closer to each other, the position of the two sets of follower plates 29 abutting against the pulleys 28 will also move away from the hysteresis sleeves 21. Under the drive of the column spring 22, the No. 2 telescopic shaft 25 can move toward the outside of the hysteresis sleeve 21, thereby releasing the column spring 22 and providing a smaller limiting capacity when the four sets of No. 2 rollers 24 are in contact with the concrete screed roller.

[0061] In summary, when dealing with concrete screed rollers of different diameters, the limiting force provided by the cylindrical spring 22 changes when the second roller 24 is in contact with the concrete screed roller. Specifically, the larger the diameter of the concrete screed roller, the greater the limiting force provided by the cylindrical spring 22, and vice versa. The significance of this setting is that the larger the diameter of the concrete screed roller, the greater its weight, and the greater the limiting force required. This effectively prevents it from separating from the four sets of second rollers 24 during rotation. Conversely, when the diameter of the concrete screed roller is small, the required limiting force is reduced. Furthermore, by reducing the limiting force, excessive limiting force can be avoided from suppressing the oscillation during rotation, making the oscillation phenomenon easier to detect and improving the accuracy of the detection results.

[0062] With the above settings, the elastic force of the cylindrical spring 22 can automatically match the diameter of the concrete leveling machine roller. On the one hand, this ensures a good limiting effect on the concrete leveling machine roller, preventing it from separating from the second roller 24 during rotation. On the other hand, it fully releases the swaying of the concrete leveling machine roller during rotation, making it easier to detect and improving the accuracy of the detection results.

[0063] Please see Figure 6 As an embodiment of the present invention, it also includes a support device 14, on which a first roller 15 for supporting the pressure roller of the concrete leveling machine is provided;

[0064] The guide plate 20 is fixedly connected to the support device 14, and the double-headed cylinder 16 is mounted on the support device 14.

[0065] The support device 14 has a built-in elastic element connected to the first roller 15. During use, when the four sets of second rollers 24 are in contact with the concrete leveling machine's pressure roller, due to the gravity of the pressure roller, the vertical distance between the lower second roller 24 and the vertical plane passing through the axis of the concrete leveling machine's pressure roller is always greater than the vertical distance between the upper second roller 24 and the vertical plane on the same side of the pressure roller. At this time, when the concrete leveling machine's pressure roller rotates, there is a vertical distance between the pressure roller and the two rollers below it. There is a possibility of slippage between the two No. 2 rollers 24. At this time, the support device 14 can drive the elastic element to move upward and act on the No. 1 roller 15 so that the two No. 2 rollers 24 on the same side of the concrete leveling machine pressure roller are in the same vertical plane. That is, the elastic force provided by the elastic element at this time just cancels out the weight of the concrete leveling machine pressure roller, thus ensuring that the four sets of No. 2 rollers 24 are in a plane inclined at 45° in the radial direction of the concrete leveling machine pressure roller, thereby ensuring the limiting effect on the concrete leveling machine pressure roller, so that the force is more balanced when it rotates and swings, and thus preventing slippage.

[0066] Please see Figures 7-9 As one embodiment of the present invention, it also includes: a frame 1, a universal connector and a telescopic ring 12.

[0067] The frame 1 is provided with a side frame 2;

[0068] The universal connector is connected to the side frame 2. A rotating sleeve 8 is rotatably mounted on the universal connector. The rotating sleeve 8 is provided with multiple sets of rubber abutment parts 11 at equal intervals around the circumference.

[0069] A through groove is formed on the side frame 2. The universal connector includes a rotating frame 3 rotatably installed in the through groove. A rotating plate 4 is rotatably installed in the rotating frame 3. The rotation center of the rotating frame 3 is perpendicular to the rotation center of the rotating plate 4.

[0070] The drive device 5, which is fixedly installed on the rotating plate 4, is connected to the rotating sleeve 8.

[0071] During testing, the concrete leveling machine roller is coaxially and fixedly connected to the rotating sleeve 8. At the same time, during testing, the output shaft of the drive device 5 can drive the concrete leveling machine roller to rotate through the rotating sleeve 8. If the center of gravity of the concrete leveling machine roller is eccentric, it will inevitably swing when rotating, causing the drive device 5 to swing. If the drive device 5 is directly connected to the side frame 2, the output shaft of the drive device 5 will be twisted for a long time during testing, resulting in metal fatigue or loosening of the connection between the side frame 2 and the frame 1.

[0072] In the embodiment, the rotating frame 3 can rotate longitudinally relative to the side frame 2, and the rotating plate 4 can rotate laterally relative to the rotating frame 3, so that the two can be connected in a universal manner. When the pressure roller of the concrete leveling machine swings, it can drive the output shaft of the drive device 5 to swing synchronously, avoiding the output shaft of the drive device 5 from breaking due to metal fatigue. Moreover, the swinging force will not be transmitted to the side frame 2, avoiding the situation where the connection between the side frame 2 and the frame 1 becomes loose.

[0073] Please see Figure 5 The telescopic ring 12 is coaxial with the rotating sleeve 8. The telescopic ring 12 is connected to the rubber abutment 11 through a guide structure. The guide structure includes through holes that are circumferentially equidistant on the side wall of the rotating sleeve 8. Side plates 9 are provided on both sides of the through holes.

[0074] The guide structure also includes an abutment plate 10 slidably disposed between the two side plates 9. One end of the abutment plate 10 is connected to the rubber abutment member 11, and the other end is sleeved with a sliding connecting shaft 13 disposed on the telescopic ring 12.

[0075] The abutment plate 10 is also provided with a first inclined block 1001, which is slidably connected to a first inclined groove 901 provided on the side plate 9.

[0076] Two electric telescopic rods 6 are arranged diagonally on the rotating plate 4. A grooved wheel 7 is rotatably installed on the actuating end of the electric telescopic rod 6. The inner convex ring 1201 located inside the telescopic ring 12 rolls with the grooved wheel 7.

[0077] In use, one end of the concrete leveling machine's roller is placed inside the rotating sleeve 8. The movement of the electric telescopic rod 6 is controlled, causing the telescopic ring 12 to move relative to the rotating plate 4. When the telescopic ring 12 moves towards the rotating plate 4, the sliding connecting shaft 13 drives the abutment plate 10 towards the rotating plate 4. With the cooperation of the first inclined block 1001 and the first inclined groove 901, the abutment plate 10 will also move towards the interior of the rotating sleeve 8 until the rubber abutment piece 11 at the end of the abutment plate 10 abuts against the concrete leveling machine's roller. Then, the telescopic ring 12 will continue to move a certain distance, allowing the abutment plate 10 to compress the rubber abutment piece 11. During compression... During the process, the abutment plate 10 also tends to move towards the rotating plate 4, so that the concrete screed roller can be further pushed into the rotating sleeve 8. Specifically, in the initial state, the concrete screed roller abuts against the inner wall of the rotating sleeve 8, so that the rubber abutment 11 can clamp the concrete screed roller while making the concrete screed roller tend to move further into the rotating sleeve 8, thereby ensuring the abutment force between the rotating sleeve 8 and the concrete screed roller in the circumferential and horizontal directions, avoiding the phenomenon of the concrete screed roller and the rubber abutment 11 separating when the concrete screed roller rotates and swings, and improving the connection stability between the two.
