Description

Technical Field

[0001] This utility model relates to the field of vibration damping technology, and in particular to a vibration damping and isolation base for a testing device. Background Technology

[0002] A total station, also known as a total station electronic tachometer, is an instrument that, once observations are made at a station, automatically displays necessary data such as slope distance, zenith distance (vertical angle), and horizontal angle, and obtains horizontal distance, elevation difference, and point coordinates almost simultaneously. By connecting the data terminal acquired in the field by the total station to a computer or plotter via a transmission interface, and using data processing and plotting software, automated mapping can be achieved. It is widely used in precision engineering surveying or deformation monitoring for large above-ground buildings and underground tunnel construction.

[0003] When using total stations during underground tunnel construction, they are often used on tunnel boring machines. In this special environment, the total station vibrates greatly during measurement, which significantly affects the measurement accuracy and requires improvement. Utility Model Content

[0004] The purpose of this invention is to propose a vibration damping and isolation bracket with good vibration damping function, which enables the testing equipment to maintain high measurement accuracy even in a vibration environment.

[0005] This utility model proposes a vibration damping and isolation base for a testing device, comprising a vibration damping disc, several vibration isolation components, and a base frame. The testing device is fixedly mounted on the vibration damping disc, which is located above the base frame. Several vibration isolation components are disposed between the base frame and the vibration damping disc, and are respectively fixed to the base frame and the vibration damping disc. Each vibration isolation component includes a mounting plate and a vibration isolator. The mounting plate is fixedly mounted to the base frame, and the vibration isolator is fixedly mounted to the vibration damping disc. The base frame includes several vertical rods and several horizontal beams. The two ends of each horizontal beam are respectively connected and fixed to the vertical rods. Both the vertical rods and the horizontal beams are hollow structures. A vibration damping cavity is formed inside the vibration damping disc. Several damping particles are disposed inside the vertical rods, horizontal beams, and vibration damping cavities.

[0006] Preferably, a mounting groove is formed at the center of the vibration damping disc, the testing device is fixedly installed in the mounting groove of the vibration damping disc, and the vibration damping cavity surrounds the periphery of the testing device.

[0007] Preferably, the base frame further includes a mounting frame, which includes a mounting ring, a plurality of extension rods and a plurality of mounting platforms. The mounting ring is fixedly mounted on the base frame, the plurality of extension rods are distributed around the periphery of the mounting ring and one end is fixed to the mounting ring, and the mounting platforms are fixed on each extension rod; the mounting plate is fixedly mounted on the mounting platform.

[0008] Preferably, the mounting plate and the mounting platform are fixed together by bolts, and the vibration isolator and the vibration damping disc are fixed together by bolts.

[0009] Preferably, the vibration isolator is selected from one of the following: a quasi-zero stiffness vibration isolator, a spring vibration isolator, a metal-rubber vibration isolator, or a rubber vibration isolator.

[0010] Preferably, the vertical rod is composed of several rod segments, each rod segment including a rod body and a connector. The rod body is opened through along its length direction, and the connector is opened through to form a connecting hole. The connector is partially sleeved around the rod body and fixed to the rod body. The rod body parts of two adjacent rod segments pass through the same connecting hole and abut against each other.

[0011] Preferably, the two ends of the rod body are sealed with partitions, and a sealed cavity is formed between the rod body and the two partitions. A number of damping particles disposed in the vertical rod are located in each sealed cavity.

[0012] Preferably, the mass ratio between the detection device and the damping particles is set to 1:4.

[0013] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0014] 1. After the testing equipment (total station) is installed on the vibration damping and isolation base, the damping particles in the damping cavity play a role in damping the testing equipment (total station), the vibration isolator plays a role in isolating the testing equipment (total station), and the damping particles in the crossbeam and vertical rod play a role in damping the testing equipment (total station) again. Thus, by first damping the testing equipment (total station), then isolating it, and then damping it again, the testing equipment (total station) can still have high measurement accuracy in a vibration environment.

[0015] 2. The vertical rod is composed of several rod segments. When assembling and installing the rod segments, the rod body of one rod segment is inserted into the connecting hole of the connector of another rod segment so that the rod bodies of the two rod segments abut against each other. This allows the length of the vertical rod to be adjusted so that the testing equipment (total station) installed on the vibration damping and isolation base can adapt to measurements at different heights.

[0016] 3. Partitions are sealed at both ends of the rod body, forming a sealed cavity between the rod body and the two partitions. Several damping particles are located in each sealed cavity within the vertical rod. This allows the damping particles to be relatively evenly distributed along the length of the vertical rod, preventing the damping particles from accumulating at the bottom of the vertical rod.

[0028] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-10 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0029] Reference Figure 1 , Figure 2 and Figure 3, A vibration isolation base for a detection device, comprising a vibration damping disc 1, several vibration isolation components 2 and a base frame 3. Each vibration isolation component 2 is fixedly arranged on the base frame 3, the vibration damping disc 1 is fixedly arranged on each vibration isolation component 2, and the detection device is fixedly installed on the vibration damping disc 1. The detection device can be a total station 5. After the total station 5 is fixedly installed on the vibration damping disc 1, in order to make the total station 5 firmly installed on the vibration damping disc 1, an installation groove 11 is formed on the surface of the vibration damping disc 1; thus, the total station 5 is installed in the installation groove 11 of the vibration damping disc 1, and the total station 5 and the vibration damping disc 1 are fixed by bolt locking. A vibration damping cavity 12 is formed in the vibration damping disc 1. The formed vibration damping cavity 12 surrounds the periphery of the installation groove 11, and damping particles 4 are arranged in the vibration damping cavity 12. The arrangement of the damping particles 4 in the vibration damping cavity 12 plays a vibration damping effect on the total station 5 fixedly installed on the vibration damping disc 1.

[0030] Refer to Figure 4 and Figure 5 , The base frame 3 includes an installation frame 31, four vertical rods 33 and ten cross beams 32. The two ends of each cross beam 32 are fixedly installed on two vertical rods 33 respectively. Four cross beams 32 are located at the bottom ends of the vertical rods 33 and surround to form a "square" shape; another six cross beams 32 are located at the top ends of the vertical rods 33 and are in a "eye" shape. The installation frame 31 is fixedly installed on the cross beam 32 at the top end of the vertical rod 33. The provided installation frame 31 includes an installation ring 311, several extension rods 312 and several installation platforms 313. The installation ring 311 is fixedly installed on the cross beam 32 at the top end of each vertical rod 33. Each extension rod 312 is evenly arranged around the periphery of the installation ring 311 and one end is fixed to the installation ring 311; each installation platform 313 is fixedly installed on the end of each extension rod 312 far from the installation ring 311 by bolt locking. In order to further improve the vibration damping effect of the base frame 3 on the total station 5, each cross beam 32 and each vertical rod 33 are set to be hollow, and several damping particles 4 are arranged in both the cross beam 32 and the vertical rod 33.

[0031] Refer to Figure 6The vibration isolation assembly 2 is configured to include a mounting plate 21 and a vibration isolator 22, with the vibration isolator 22 fixed to the mounting plate 21. During installation, the mounting plate 21 of each vibration isolation assembly 2 is fixed to the mounting platform 313 using bolts. The damping disc 1 is mounted against the vibration isolator 22 of each vibration isolation assembly 2, and the vibration isolator 22 is fixed to the damping disc 1 using bolts. The vibration isolator 22 is selected from one of the following: a quasi-zero stiffness vibration isolator, a spring vibration isolator, a metal-rubber vibration isolator, or a rubber vibration isolator. The principle of this vibration isolation assembly 2 is to combine one of metal-rubber, rubber, or spring with a negative stiffness mechanism to offset stiffness at a specific operating point, achieving extremely low effective stiffness, thereby improving the low-frequency vibration isolation effect. In this vibration damping and isolation base, the vibration damping plate 1 dampens the vibration of the total station 5, followed by the vibration isolation component 2, and finally, the damping particles 4 within the crossbeam 32 and vertical rod 33 further dampen the vibration of the total station 5. This results in less vibration generated by the total station 5 when measuring on the tunnel boring machine, thus enabling the total station 5 to achieve higher measurement accuracy in this environment.

[0032] Reference Figure 7 and Figure 8 To ensure that the total station 5, after being fixedly installed on the vibration-damping base, can meet the measurement requirements at different heights, the vertical rod 33 is configured to consist of several rod segments 331. Each rod segment 331 consists of a rod body 3311 and a connector 3312, which are formed through the rod body 3311 along its length. A connecting hole 3313 is formed in the connector 3312. One end of the rod body 3311 is inserted into the connecting hole 3313 of the connector 3312, so that the connector 3312 partially fits around the rod body 3311, and the rod body 3311 and connector 3312 in the same rod segment 331 are welded and fixed together. When the total station 5 is used for measurement, a corresponding number of pole segments 331 are selected according to the required measurement location height. The pole body 3311 of one pole segment 331 is inserted into the connecting hole 3313 of another pole segment 331 until the pole body 3311 abuts against the pole body 3311 of the other pole segment 331. The pole body 3311 and connecting piece 3312 of different pole segments 331 are then fixed together using bolts (not shown in the figure), thus achieving detachable installation of each pole segment 331. The vertical rod 33 of the base is formed by the detachable installation of multiple pole segments 331, allowing for height adjustment of the vertical rod 33, enabling the total station 5 to adapt to measurements at different heights after installation.

[0033] Reference Figure 8 , Figure 9 and Figure 10After the various rod segments 331 are assembled together, damping particles 4 are injected into the rod segments 331, thereby enabling the base to also dampen the vibration of the total station 5. To ensure that the base has a good vibration reduction effect on the total station 5, sealing plates 3314 are provided at both ends of the rod segments 331, forming a sealed cavity 3315 between the rod segments 331 and the two seals. The damping particles 4 are injected into the sealed cavity 3315 of each rod segment 331 beforehand. Thus, when the vertical rod 33 is assembled from several rod segments 331, the damping particles 4 are relatively evenly distributed within the vertical rod 33 to prevent the damping particles 4 from accumulating completely at the bottom of the vertical rod 33. In the vibration damping and isolation base of the total station 5, damping particles 4 are installed in the damping cavity 12, the crossbeam 32, and the vertical rod 33. The mass ratio between the total station 5 and all the damping particles 4 is set to 1:4, thereby enabling the base to have a good vibration damping effect on the total station 5. In this vibration damping and isolation base, the damping particles 4 in the damping cavity 12 damp the total station 5, the vibration isolation component 2 isolates the total station 5, and finally the base frame 3 dampens the total station 5 again. This completes the process of first damping, then isolating, and then damping again, so as to maintain the stability of the total station 5 during the measurement process.

[0034] The specific implementation principle of this application embodiment is as follows: When the total station 5 needs to be used for measurement in a vibrating environment, according to the required measurement height of the total station 5, a suitable number of pole segments 331 are selected, and the connector 3312 of one pole segment 331 is sleeved on the pole body 3311 of another pole segment 331, so that the pole bodies 3311 of the two pole segments 331 abut against each other. This allows the vertical rod 33 of the frame 3 to be detachably installed, and after installation, the total station 5 is at a suitable measurement height.

[0035] During measurements in a vibrating environment, the damping particles 4 within the vibration damping cavity 12 effectively reduce vibration in the total station 5. Simultaneously, the vibration isolators 22 within the vibration isolation assembly 2 provide effective vibration isolation for the total station 5. Furthermore, several damping particles 4 are installed within the crossbeam 32 and vertical rod 33 of the base frame 3. The damping particles 4 within the vertical rod 33 are located within the sealed cavities 3315 of each rod segment 331, thus providing further vibration damping for the total station 5 through the base frame 3. Sealing plates 3314 at both ends of each rod segment 331 act as barriers to prevent the damping particles 4 from accumulating at the bottom of the vertical rod 33, ensuring a relatively uniform distribution of the damping particles 4 within the vertical rod 33. This vibration damping and isolation base performs a cycle of first damping, then isolation, and then damping again for the total station 5, maintaining its stability during measurements.

[0036] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
