DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0029] like Figure 1-7 As shown, a testing device 100 for a concrete vibrating ruler (hereinafter referred to as a vibrating ruler) in one embodiment of the present invention includes a frame 10 and a testing mechanism 20. An openable testing space is provided in the frame 10. The testing mechanism 20 is arranged in the testing space in the frame 10 and includes a base plate 21 supported at the bottom of the frame 10 by multiple springs 22, and a fixing component 23 fixed on the base plate 21 for fixing the concrete vibrating ruler.

[0030] Because vibrating rulers generate significant noise during operation, the test apparatus 100 in this embodiment is equipped with an openable test chamber, specifically, a hatch (not shown for ease of demonstration). After the vibrating ruler to be tested is placed inside, the hatch is closed, creating a relatively enclosed space and reducing noise. Furthermore, springs 22 support the base plate 21 and the mounting assembly 23, filtering the vibrations generated by the vibrating ruler and preventing or reducing the transmission of these vibrations to the frame 10, further reducing noise.

[0031] Preferably, in order to improve the stability of the spring 22, guide columns are provided at the bottom of the base plate 21 and the bottom of the frame 10. Figure 3 As shown, a first guide post 211 is fixed to the bottom of the base plate 21, and a second guide post 13 is fixed to the bottom of the frame 10. The spring 22 is mounted on the guide posts at both ends to prevent the spring 22 from shifting. The guide posts at both ends also provide a buffer in the event of spring failure, preventing the base plate 21 from directly hitting the bottom of the frame 10.

[0032] Preferably, sound insulation cotton or sound insulation board can be laid on the inner wall of the frame 10 to reduce noise.

[0033] The fixing assembly 23 includes a first guide rail 2311 installed on the base plate 21, and a platform 232 supported on the first guide rail 2311. One end of the first guide rail 2311 extends to the edge of the base plate 21. The platform 232 is used to support the vibrating ruler and is equipped with multiple posts 233 for supporting the vibrating ruler's handle. After the first guide rail 2311 is installed, the platform 232 is movable within the frame 10. When installing or removing the vibrating ruler, the platform 232 can be slid close to the openable hatch, making it easier for operators to operate.

[0034] For further information, see Figure 4 As shown, a second guide rail 2312 is provided on the first guide rail 2311. The second guide rail 2312 can slide on the first guide rail 2311, and the carrier 232 is supported on the second guide rail 2312. The first guide rail 2311 and the second guide rail 2312 constitute a two-section guide rail. Since the first guide rail 2311 extends to the edge of the bottom plate 21, when the second guide rail 2312 is moved to the edge of the bottom plate 21, the carrier 232 can be moved to the outside of the frame 10 by continuing to move, making it easier for workers to disassemble and assemble the vibrating ruler.

[0035] To improve the stability during testing, Figure 2 and Figure 5 As shown, the fixing assembly 23 also includes two clamping plate assemblies disposed on either side of the platform 232. Each clamping plate assembly includes a toggle clamp cylinder 234 and a clamping block 235 connected to the output shaft of the toggle clamp cylinder 234. After the vibrating ruler is placed on the platform 232, the toggle clamp cylinder 234 drives the clamping block 235 to rotate toward the vibrating ruler, pressing the vibrating ruler against the platform 232 from both sides, preventing the vibrating ruler from shifting due to vibration or even sliding off the platform 232.

[0036] During the test, the motor speed test of the vibrating ruler is required, so Figure 7 As shown, in one embodiment, the testing mechanism 20 is further provided with a speed measurement component, which includes a magnetic flux leakage speed sensor 24 disposed above the carrier 232. During operation, the vibrating ruler motor generates a rotating magnetic field and also generates magnetic flux leakage. The motor rotor winding cuts magnetic lines of force in the rotating magnetic field, generating an induced current. The frequency of this induced current is related to the motor speed. The motor speed is measured by detecting this magnetic flux leakage. Therefore, the magnetic flux leakage speed sensor 24 can be used to non-contact monitor the motor speed of the vibrating ruler, expanding the test range and improving ease of use.

[0037] Preferably, the speed measuring assembly also includes a mounting bracket 25 fixed to the base plate 21, and a speed measuring cylinder 26 fixed to the mounting bracket 25. The mounting bracket 25 is arranged on one side of the carrier 232, and the leakage magnetic speed measuring sensor 24 is fixed on the output shaft of the speed measuring cylinder 26. Only after the carrier 232 on which the vibrating ruler is placed moves to the test position, the speed measuring cylinder 26 drives the leakage magnetic speed measuring sensor 24 to move to a position close to the vibrating ruler motor before the test is performed. This arrangement can effectively protect the leakage magnetic speed measuring sensor 24 and prevent the direct movement of the carrier 232 from causing the vibrating ruler to collide, thereby preventing the leakage magnetic speed measuring sensor 24 from being damaged.

[0038] Furthermore, the speed measurement assembly includes a baffle 27 mounted on the mounting bracket 25. This baffle 27 is L-shaped and extends along the output direction of the speed measurement motor 26. It includes a first surface 271 perpendicular to the carrier 232, and a second surface 272 connected to the top of the first surface 271 and parallel to the first surface. The speed measurement cylinder 26 is positioned between the first surface 271 and the second surface 272. It can drive the leakage magnetic speed measurement sensor 24 to move until it is exposed on the baffle 27 (test position), or to move between the first surface 271 and the second surface 272 until it is completely retracted into the baffle 27. The baffle 27 protects the speed measurement cylinder 26 and the leakage magnetic speed measurement sensor 24 from being damaged by the vibrating scale.

[0039] Furthermore, to enhance the stability of the platform 232, the fixing assembly 23 also includes a plurality of bars fixed to the base plate 21, including a first bar 236 perpendicular to the first guide rail 2311, and a second bar 237 fixed to both ends of the first bar 236 and extending toward the platform 232. The first bar 236 and the second bar 237 define the movable position of the platform 232. Specifically, when the platform 232 abuts the first bar 236 and the second bar 237, the position of the vibrating ruler is the testing position.

[0040] A groove 2371 for accommodating the carrier 232 is formed on the second stop bar 237 . When the carrier 232 moves to the testing position, it is partially inserted into the groove 2371 to prevent the vibrating ruler from causing the carrier 232 to vibrate.

[0041] Since vibrating rulers are typically equipped with an overload indicator light, when the motor is overloaded, the indicator light will light up to remind the operator to stop operation and check to avoid damage to the vibrating ruler. Therefore, to monitor the status of the vibrating ruler during testing, the testing mechanism 20 also includes a light sensor 29 disposed above the carrier 232. The light sensor 29 is fixed to the side wall of the frame 10 and faces and monitors the overload indicator light on the vibrating ruler. The light sensor 29 is connected to a prompt mechanism (such as a light or buzzer light) on the frame 10 to alert the tester when the vibrating ruler motor is overloaded, thereby preventing damage to the vibrating ruler.

[0042] Preferably, third guide rails 28 are fixed to two opposing side walls of the frame 10, perpendicular to the first guide rails 2311. Optical sensors 29 are supported on the third guide rails 28 and are movable on the third guide rails 28. Only after the vibrating ruler has moved to the test position is the optical sensor 29 moved to a position close to the vibrating ruler overload indicator for monitoring. At other times, the optical sensor 29 can be moved close to the side wall of the frame 10 to avoid damage from being struck by the vibrating ruler.

[0043] Furthermore, a fourth guide rail (not shown) can be provided on the third guide rail 28, which extends in the vertical direction, so that the optical sensor 29 can move simultaneously in the vertical and horizontal directions in the rack 10 to adapt to the vibrating ruler with different positions of the overload indicator light, thereby further improving flexibility and ease of use.

[0044] like Figure 2 As shown, a switch handle 11 is also provided above the carrier 232, which can be connected to the vibrating ruler via a power cord and can be started remotely during testing.

[0045] In one embodiment, the rack 10 employs a two-tier design. The test mechanism 20 is located in the lower tier, while the upper tier houses an electrical cabinet, which houses the electrical control system for the test mechanism 20, including electrical panels, electronic loads, and a power supply. Multiple pulleys 12 are also provided at the bottom of the rack 10, allowing for mobility and flexibility of the entire test apparatus 100.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0047] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
