Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

Examples

In order to improve and survey precision and observation efficiency, reduce monitoring safety risk, the utility model provides an open caisson gesture monitoring sectional shelf assembly, as shown in fig. 1-3, specifically including GNSS flowing station pillar 3, GNSS flowing station pillar 3 is vertical to be welded in open caisson 12 top surface, GNSS flowing station pillar 3 passes through fixing device to be fixed at open caisson 12 top surface outer edge position department, GNSS flowing station pillar 3 top is provided with GNSS flowing station connecting rod 4, set up GNSS flowing station receiver 5 on the GNSS flowing station connecting rod 4, the upper portion of GNSS flowing station pillar 3 is provided with total powerstation prism support 6, be provided with prism adapter 7 on the total powerstation prism support 6, prism adapter 7 installation simplex prism head 8.

When the device is used for monitoring, a plurality of devices are arranged at the outer edge of the open caisson 12 according to actual conditions, then a plurality of GNSS mobile station receivers 5 and GNSS hosts are connected through cables, and the GNSS hosts are data collecting and processing devices, so that the automatic monitoring of the open caisson posture and the data transmission and downloading are realized. A single prism lens 8 of the total station is installed on a prism adapter 7 for a long time, and the total station is adopted to automatically search and aim at the center of the prism, so that the open caisson posture is manually monitored. When the device monitors, the total station can directly aim at the prism center of the single prism lens 8 in the device, monitoring can be completed without the need of measuring staff reaching a monitoring position point, the observation speed is greatly improved, the monitoring point is not required to be aligned by eyes manually, centering errors can be reduced, and the observation efficiency is improved.

If 4 monitoring points are synchronously observed, 4 GNSS mobile station receivers 5 are fixed on a GNSS mobile station connecting rod 4 by adopting the fixing support, and attitude monitoring can be quickly completed only by downloading and calculating data by one measurer, compared with the prior art that 1 measurer holds the GNSS mobile station receivers 5 to observe the 4 monitoring points one by one, the calculated attitude of the open caisson 12 is distorted due to the fact that the time cannot be consistent and the attitude of the open caisson changes rapidly and changes every moment, and the attitude calculation is performed by adopting the data at different times, the monitoring precision is improved; and 4 people measure simultaneously with prior art, directly leave out 3 survey crew, labour saving and time saving practices thrift manpower resources, improves monitoring efficiency.

Furthermore, two communicated reserved cable holes 9 are formed in the column body of the GNSS mobile station support column 3. The cable wire connected between the GNSS rover receiver 5 and the GNSS host can be hidden in the reserved cable hole 9, and the service life of the cable wire is prolonged.

Further, the fixing device comprises an upper inclined strut 1 and a lower inclined strut 2 which are symmetrically arranged along the GNSS mobile station strut 3, the upper inclined strut 1 is fixedly arranged on the top surface of the open caisson 12, and the lower inclined strut 2 is fixedly arranged on the side wall of the open caisson 12. Because above-mentioned device mainly installs in open caisson 12 top surface edge, and open caisson 12 top surface is main pedestrian passageway simultaneously, and personnel's mobility is big, consequently, GNSS mobile station pillar 3 highly can set up more than 1.5m in this application, avoids personnel to bump GNSS mobile station receiver 5 to influence measurement accuracy, simultaneously, need set up double-deck bracing and increase the stability that GNSS mobile station surveyed pillar 3, double-deck bracing mainly is last bracing 1 and lower bracing 2 along GNSS mobile station pillar 3 symmetry setting, it is in to go up the fixed setting of bracing 1 open caisson 12 top surface, down bracing 2 is fixed to be set up open caisson 12 lateral walls. But not limited to the fixing device, in particular, the fixing device can be set according to the stability and the space size of the GNSS mobile station after the observation pillar is welded with the top surface of the open caisson.

Further, total powerstation prism support 6 is right angle triangular support, one of them right-angle side setting of right angle triangular support is on GNSS mobile station pillar 3, and another right-angle side fixed mounting prism adapter 7. Total powerstation prism support 6 adopts the right angle triangle-shaped, not only is convenient for weld, can keep the top surface angle steel level moreover. The prism adapter 7 is provided with a total station single prism lens 8, so that the open caisson posture can be monitored manually.

Further, a plurality of bolt holes 10 are distributed on one of the right-angle sides of the right-angle triangular support at equal intervals, the GNSS mobile station strut 3 is provided with reserved holes at equal intervals, the interval between the reserved holes is equal to or smaller than the interval between the bolt holes 10, the axial length of the bolt holes 10 in the vertical direction is larger than the axial length of the reserved holes in the vertical direction, and the bolt holes 10 are connected with the reserved holes through connecting bolts 11. In the above design, because the prepared hole interval is equal to or less than the bolt hole 10 interval, the axial length of the bolt hole 10 in the vertical direction is greater than the axial length of the prepared hole in the vertical direction, the height of the right-angle triangular support can be adjusted, so that the height of the total station observation support of the plurality of open caisson monitoring points is kept consistent, and the measurement precision is increased.

Further, the number of the bolt holes 10 is 2, and when the number of the bolt holes 10 is 2, the bolt holes are stable, and are convenient to mount and dismount.

The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
