Abstract
Description
Technical Field
[0001] This utility model belongs to the field of precision measuring instrument technology, and specifically relates to an adjustable forced centering device. Background Technology
[0002] Existing slope early warning systems mostly employ GNSS automated monitoring to achieve real-time automated monitoring of landslide surface displacement. The working principle is as follows: receivers at each GNSS monitoring point and reference point receive GNSS signals in real time and transmit them to the control center in real time via a data communication network. The GNSS data processing and analysis software on the control center server calculates and obtains the real-time three-dimensional coordinates of each monitoring point. By comparing these coordinates with the initial coordinates, the change in the monitoring point is obtained. At the same time, the analysis software issues an over-limit alarm based on the pre-set warning value.
[0003] Surface three-dimensional displacement is monitored automatically via GNSS, primarily at locations of significant slope surface deformation. By monitoring the three-dimensional displacement of the slope surface, the deformation characteristics, amplitude, direction, rate, stability, and development trend of the slope are analyzed and determined. To ensure the accuracy of the final measurement results from GNSS automated monitoring, the relevant equipment for this monitoring method needs to be installed on a forced centering device to reduce errors during the monitoring process.
[0004] Traditional forced centering devices typically consist of a base plate fixed to a base (such as an observation pier or connecting plate) and an instrument plate connected to the bottom of the measuring instrument or target. Forced centering is achieved through a precise bushing structure. However, in practical applications, especially in complex or constrained measurement environments, the ease of adjustment of existing forced centering devices is significantly insufficient: 1. When installing instruments or targets, especially when there is a large initial positional deviation between the base plate and the instrument plate (e.g., heavy instruments, single-person operation, or environmental influences such as wind), accurately fitting the instrument plate into the base plate often requires repeated attempts and fine adjustments, a time-consuming and laborious process that is prone to damage to the precision mating surfaces due to impacts; 2. Most current forced centering devices lack leveling capabilities, therefore, they need to be leveled before installing the measuring instrument; 3. The adjustment location is limited (e.g., below the instrument plate, in a blind spot, or in an area with dense equipment), leading to inconvenience in operation. Utility Model Content

[0033] Example
[0034] like Figures 1 to 4 As shown, an adjustable forced centering device specifically includes a fixed base 100, on which a leveling mechanism 200 is mounted. The leveling mechanism 200 includes a docking mounting platform 210, with a quick-connect insertion port 211 penetrating through its center. Notably, a bubble level 212 is also mounted on the docking mounting platform 210. The adjustable forced centering device further includes a quick-connect mechanism 300, which includes a flexible insert 310. The quick-connect mechanism 300 is quickly inserted into the quick-connect insertion port 211 via the flexible insert 310. In practice, the measuring instrument is mounted on the quick-connect mechanism 300, allowing for rapid installation onto the forced centering device. The leveling mechanism 200 then performs rapid leveling calibration. This forced centering device enables centering adjustments during installation without disassembling the instrument or device, improving measurement accuracy.
[0035] In some preferred embodiments, the fixed base 100 is provided with a connecting ball head 110, and the bottom surface of the docking installation platform 210 is provided with a connecting ball sleeve 220. The connecting ball sleeve 220 communicates with the quick docking port 211. The connecting ball sleeve 220 is fitted on the connecting ball head 110 and forms a universal rotating ball hinge support with the connecting ball head 110. The leveling mechanism 200 also includes four adjustable feet, evenly distributed circumferentially around the quick-connect socket 211. Each adjustable foot includes a threaded sleeve 230, a screw 240, an adjusting nut 250 with a drive handle, and a limiting block 260. The limiting block 260 is installed on the bottom surface of the docking installation platform 210, the screw 240 is installed on the limiting block 260, and the adjusting nut 250 with a drive handle is installed on the end of the threaded sleeve 230. The adjusting nut 250 with a drive handle is threadedly connected to the screw 240. The lower end face of the threaded sleeve 230 abuts against the fixed base 100. By rotating the adjusting nut 250 with a drive handle, the length of the threaded sleeve 230 extending beyond the screw 240 can be adjusted. The levelness of the docking installation platform 210 can be adjusted using the four adjustable feet. While adjusting, the bubble in the bubble level 212 can be observed to ensure it is centered.
[0036] Preferably, the center of the docking installation platform 210 is provided with an insert sleeve 270, the insert sleeve 270 is connected to the quick docking port 211, and a pressing groove 271 is provided through the circumference of the insert sleeve 270.
[0037] In some preferred embodiments, the resilient insert 310 includes a plurality of resilient prongs 311, a base 312, a pressure plate 313, a threaded rod 314, and a locking nut 315. The resilient prongs 311 are mounted on the bottom of the base 312, and the threaded rod 314 is mounted on the top of the base 312. The resilient prongs 311 are radially compressed along the threaded rod 314 to insert them into the insert sleeve 270. Each resilient prong 311 has a locking block at its end. When the locking block of the resilient prong 311 is engaged, it releases pressure from the insert sleeve 270. When the quick-connecting connector 211 extends, several of the resilient prongs 311 expand radially along the threaded rod 314 to engage (tighten) within the insert sleeve 270. The pressure plate 313 is fitted onto the threaded rod 314, and the locking nut 315 is threadedly connected to the threaded rod 314 to press the pressure plate 313 between the locking nut 315 and the upper end face of the insert sleeve 270. At this time, the locking nut 315 is tightened so that the upper end face of the engaging block abuts against the bottom surface of the docking mounting platform 210. By tightening, the resilient insert 310 is fixedly installed on the insert sleeve 270.
[0038] Furthermore, to adjust the installation height of the measuring instrument, several semi-circular extension blocks 316 can be fitted onto the threaded rod 314. Tightening the locking nut 315 presses the pressure plate 313 between the semi-circular extension blocks 316 and the upper end face of the insert sleeve 270. The installation height of the measuring instrument can be adjusted by increasing or decreasing the number of semi-circular extension blocks 316.
[0039] In some preferred embodiments, a base plate 317 is also installed at the upper end of the threaded rod 314, and the base plate 317 is threadedly connected to the threaded rod 314. A threaded connector 318 is provided at the center of the upper end face of the base plate 317, and the measuring instrument is mounted on the base plate 317 through the threaded connector 318.
[0040] In summary, this utility model provides an easily adjustable forced centering device. Measuring instruments can be quickly installed onto the forced centering device via a quick-connect mechanism and rapidly calibrated horizontally via a leveling mechanism. This forced centering device enables centering adjustments during installation without disassembling the instrument or device, improving measurement accuracy. Furthermore, the forced centering device allows for adjustment of the instrument's installation height by increasing or decreasing the number of semi-circular heightening blocks. This utility model features a simple structure, quick and convenient installation, and allows for rapid adjustment and calibration when measurement inaccuracies are detected during precision measurement operations.
