Description

Technical Field

[0001] This invention relates to the field of spring vibration isolators, specifically to a distance measuring fixture and leveling method for releasing and leveling a steel spring vibration isolator. Background Technology

[0002] Steel spring vibration isolators are widely used in precision equipment foundations, building structure vibration reduction, and other fields. Their core function is to isolate vibration through the elastic deformation of the steel spring. In the final stage of installation and commissioning, a "release and leveling" operation is required. This involves unloading the temporary construction supports and ensuring the isolator reaches the design elevation and levelness under permanent load. The key to this process is accurately measuring the real-time distance change between the top surface of the isolator's lower housing (or upper flange) and the bottom surface of the superstructure (such as the upper support).

[0003] Currently, the commonly used measurement methods mainly rely on manual operation using measuring tapes, vernier calipers, or ordinary laser rangefinders. These methods suffer from problems such as inconsistent measurement benchmarks and difficulty in accurately locating measurement points, leading to significant data errors. Furthermore, in confined or high-altitude working environments, the stability of the instruments held by personnel is poor, and readings are difficult, making operation extremely inconvenient. In addition, each measurement point requires repeated centering and measurement, and the overall leveling process is time-consuming, labor-intensive, and inefficient.

[0004] To address this, a distance measuring fixture for releasing and leveling a steel spring vibration isolator is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a ranging fixture for releasing and leveling a steel spring vibration isolator, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ranging fixture for releasing and leveling a steel spring vibration isolator, comprising a ranging structure, wherein the ranging structure includes:

[0007] Mounting plate;

[0008] A positioning structure is provided at the bottom of the mounting plate for positioning cooperation with the lower housing of the vibration isolator and for detachably fixing the ranging structure thereon;

[0009] A laser ranging probe is mounted on the mounting plate. After the ranging structure is fixed by the positioning structure, its laser beam emission direction is perpendicular to the upper surface of the mounting plate and points to the bottom surface of the upper structure of the building.

[0010] A level, mounted on the mounting plate, is used to indicate the horizontal state of the mounting plate.

[0011] Preferably, the positioning structure includes a first positioning part and a second positioning part arranged at an angle to each other, and the connection between the first positioning part and the second positioning part forms a positioning inner angle for fitting with the corner of the lower housing of the vibration isolator.

[0017] Preferably, the ranging fixture is configured in at least four sets, each used to be installed at one of the four corners of the lower housing of a steel spring vibration isolator.

[0018] A method for measuring the release and leveling of a steel spring vibration isolator, using a ranging structure with any of the above technical features for measurement and leveling, includes the following steps:

[0019] S1. Fix the ranging structure onto the metal mounting surface of the pre-positioned lower housing of the vibration isolator, and use the positioning structure to quickly position it so that the mounting reference surface of the ranging structure is aligned with the mounting surface of the vibration isolator.

[0021] S3. During the release or leveling of the vibration isolator, measure the current distance value Lx in real time or at intervals;

[0022] S4. By calculating the difference ΔL=Lx-L1, the displacement change of the vibration isolator in the vertical direction can be accurately obtained to guide the leveling operation.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 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.

[0036] Please see Figures 1-3 This invention provides a technical solution for a ranging fixture used for releasing and leveling a steel spring vibration isolator:

[0037] A ranging fixture for releasing and leveling a steel spring vibration isolator includes a ranging structure 2. The ranging structure 2 includes a mounting plate 21 disposed on the mounting base surface. Taking the lower housing of the vibration isolator as an example, the mounting base surface of this application has a positioning structure 22 fixedly installed at the bottom of the ranging structure 2. Since it is the lower housing, the positioning structure 22 includes a first positioning part 221 and a second positioning part 222, which are respectively perpendicular to each other in two directions. These can be understood as L-shaped and integrally formed plates. This allows the positioning structure 22 to be installed at one corner of the lower housing 1 of the vibration isolator when the ranging structure 2 is installed as a whole. The right-angle setting of the positioning structure 22 allows its vertical edge to be positioned against the side wall of the lower housing 1 of the vibration isolator, enabling the ranging structure 2 to be quickly positioned on the lower housing 1 of the vibration isolator. This ensures the accurate installation of the ranging structure 2. After installation, a level 24 installed on the mounting plate 21 is used to assist in adjustment during installation, ensuring that the ranging structure 2 and the measuring reference surface are in a horizontal state. Additionally, a laser ranging probe 23 is installed on one side of the mounting plate 21. After installation, fixation, and calibration, ensure that the laser beam of the laser ranging probe 23 is strictly perpendicular to the installation reference plane, i.e., the top surface of the lower housing 1 of the vibration isolator. Before the leveling operation begins, install the aforementioned components. Install the four ranging structures 2 at the four corners of the lower housing 1 of the vibration isolator, respectively. Activate the ranging structures 2 and measure the initial distance Llower housing 1, i.e., the initial height from the lower housing 1 of the vibration isolator to the bottom surface 3 of the upper support. During the gradual release of temporary supports or height adjustment, the laser ranging probe 23 continuously or as instructed measures the current distance Lx. The monitoring equipment refers to a computer laptop that receives the measurement data. The computer can use software to collect, record, and analyze the measurement data, guiding precise adjustments during the release and leveling process. By calculating ΔL = Lx - Llower housing 1 of the vibration isolator, the precise vertical displacement of the vibration isolator can be obtained in real time. Based on the ΔL value of each vibration isolator, the operator judges whether the load release is uniform and whether the elevation meets the design requirements, and guides the precise adjustment until all vibration isolators are leveled. Among them, the laser ranging probe 23 can be an RW-RF-A0 micron-level precision laser ranging sensor, and the level 24 can be a 20mm bullseye level.

[0038] In an optional implementation, the thickness of the first positioning part 221 and the second positioning part 222 is selected to be 5cm. In order to meet the installation requirements, an inner arc shape is provided at the junction of the first positioning part 221 and the second positioning part 222. This inner arc shape satisfies the four right angles of the lower housing 1 of the vibration isolator.

[0039] In an optional implementation, to ensure the overall stability of the ranging structure 2 during installation and to avoid data loss during vibration isolator adjustment, magnetic fixation is used in this embodiment. A fixing slot is provided at the bottom of the mounting plate 21. To prevent the magnetic field generated by the magnetic attraction from affecting the normal operation of the laser ranging probe 23, a non-magnetic barrier ring 211 is installed inside the fixing slot. This barrier ring 211 may have a surface coated with or otherwise magnetically shielded foil. The barrier ring 211 is fixedly installed within this slot, confining most of the magnetic field within the adsorption area and protecting the subsequent electronic equipment. A permanent magnet 212 is embedded inside the barrier ring 211. The volume or magnetic force of the permanent magnet array and the sealing plate are adjusted according to the actual situation. The sealing plate seals the permanent magnet 212 inside the fixing slot, ensuring that the use of the sealing plate does not affect the magnetic attraction of the permanent magnet 212.

[0040] In an optional implementation, the laser ranging probe 23 is equipped with a data interface such as USB or RS232 on one side, which transmits the distance data measured in real time by the laser ranging probe 23 to an external tablet or data acquisition device via a data cable or wirelessly for recording, display and calculation.

[0041] In one optional implementation, the key is to accurately measure the real-time distance change between the top surface of the lower housing of the vibration isolator and the bottom surface of the superstructure, such as the upper support. However, the bottom surface of the upper support is not perfectly horizontal; there may be localized subsidence, minor bulges, or construction errors that result in it not being perfectly horizontal. This factor must be taken into account, and the building structure's vibration reduction will be affected by uneven stress due to the non-planar layout, therefore a certain safety threshold must be maintained.

[0042] like Figures 4-6 To address the issue of non-planarity, this application improves the positioning structure 22, changing its right angle to a selectable one.

[0043] Furthermore, the positioning structure 22 includes a first movable part 223 and a second movable part 224 rotatably connected at one end. The first movable part 223 and the second movable part 224 are respectively provided with a first rotating part 2232 and a second rotating part 2242. The second rotating part 2242 is inserted into a pre-reserved slot in the first rotating part 2232. Angle lines are also engraved on the first rotating part 2232 or the second rotating part 2242 to determine that one side is fixed and the other side can rotate. In this way, the included angle between the two can also be known through the angle lines. By setting damping in the rotating shaft or at the connection between the rotating shaft and the first rotating part 2232 and the second rotating part 2242, the rotation mode is that either the first rotating part 223 or the second rotating part 2242 is rotatably connected to the rotating shaft, such as the rotation connection mode of a mobile phone holder. The setting of damping should be considered to have a certain resistance to avoid the rotation being too loose, thus forming the rotatable mode of the first movable part 223 and the second movable part 224. It should be noted that, in this embodiment, since both the first movable part 223 and the second movable part 224 are located below the mounting plate 21, one of the first movable part 223 and the second movable part 224 can have a maximum range of motion of 180 degrees, with the aforementioned rotating shaft as the axis of rotation, meaning the first movable part 223 and the second movable part 224 are in a collinear position, while the other is fixed to the mounting plate 21. In this way, by rotating, the first movable part 223 and the second movable part 224 can be positioned either at a right angle as in the above embodiment, or rotated to a horizontal position. Specifically, this application does not limit the rotatable form and related rotational structure of the first movable part 223 and the second movable part 224.

[0044] To facilitate storage, a protrusion 2231 is provided on one side of the first movable part 223, and an insert 2241 matching the protrusion 2231 is provided on one side of the second movable part 224. Alternatively, the mounting plate 21 can be merged as a whole, so that the first movable part 223 and the second movable part 224 can be rotated and fit together, while the protrusion 2231 is embedded in the insert 2241.

[0045] Thus, after achieving the aforementioned right-angled state and performing measurements, or initially, the first movable part 223 and the second movable part 224 are rotated to form a collinear state. Figure 6As shown, this allows the ranging structure 2 to slide uniformly along one side of the lower housing 1 of the vibration isolator. It's important to note that the magnetic attraction of the permanent magnet 212 does not affect its sliding. The computer then uses software to collect, record, and analyze the measurement data to obtain the precise distance between the vibration isolator and the bottom surface 3 of the upper support pier in real time. By repeatedly moving the ranging structure 2 on the lower housing 1 of the vibration isolator, the distance data is compared to determine whether the bottom surface 3 of the upper support pier is level, whether there is local subsidence or micro-protrusion, so that a safe threshold can be maintained during subsequent adjustments to the vibration isolator, or the building data of the bottom surface 3 of the upper support pier can be re-checked and the effectiveness verified.

[0046] Working Principle: During operation, before the leveling work begins, four ranging structures 2 are attached and fixed to the lower housing 1 of the isolator to be monitored using the method described above. The laser ranging probe 23 is activated to measure the initial distance Llower housing 1, which is the initial height from the bottom surface of the lower housing 1 to the bottom surface 3 of the upper support. During the gradual release of temporary supports or height adjustment, the laser ranging probe 23 continuously or as instructed measures the current distance Lx. The monitoring equipment calculates ΔL = Lx - Llower housing 1 to obtain the precise vertical displacement of the isolator in real time. Based on the ΔL value of each isolator, the operator judges whether the load release is uniform and whether the elevation meets the design requirements, and guides precise adjustments until all isolators are leveled.

[0047] This invention not only ensures the accuracy and comparability of measurement data, but also frees measurement personnel from repetitive, tedious, and risky handheld measurement tasks, thus having significant practical value.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
