Description

Anchor plate center positioning device

technical field

The utility model relates to the technical field of positioning and installation equipment for bridge anchor pads, in particular to a center positioning device for anchor pads.

Background technique

At present, during the installation, measurement and positioning of the anchor plate of the suspension bridge, due to the influence of external environmental factors such as wind, the positioning of the anchor plate exceeds the design allowable range, and the construction efficiency is low. In order to make the measurement accuracy meet the requirements, the anchor plate must be adjusted repeatedly, but during the construction process, it is cumbersome to adjust the attitude of the anchor plate by manually finding the center axis of the anchor plate. If each one is adjusted to the design position If it is fixed again, it will waste a lot of time and affect the installation progress. Therefore, it is necessary to invent a positioning device, which can change the status quo of the influence of the traditional working mode on the construction efficiency, and minimize the influence of external factors on the observation accuracy.

Utility model content

The purpose of the utility model is to provide an anchor plate center positioning device which is convenient for quickly and accurately locating the center axis of the anchor plate.

In order to achieve the above-mentioned purpose, the present utility model adopts the following technical scheme: an anchor pad center positioning device, comprising a positioning disc coaxially arranged on the anchor pad plate, and a precision total station is arranged at the center of the positioning disc. For use with measuring prisms.

Further, the aforementioned anchor plate center positioning device, wherein: the specific connection structure between the measuring prism and the positioning disk includes: a center bolt is provided at the rear end of the measuring prism, and the center bolt is from the center of the positioning disk. After passing through, a locking nut is threadedly connected, and the locking nut cooperates with the central bolt to detachably install and fix the measuring prism on the positioning disc.

Further, in the aforementioned anchor plate center positioning device, the diameter of the positioning disc is 0.5 mm smaller than the diameter of the anchor plate.

Through the implementation of the above technical solutions, the beneficial effects of the present utility model are: (1) it is convenient to locate the central axis of the anchor pad quickly and accurately, and the anchor pad can be directly determined by directly measuring the prism with a precision total station at a fixed position The position of the central axis does not need to manually find the axis point, which can avoid human measurement errors, minimize the measurement errors, improve the installation accuracy and construction efficiency of the anchor pad, and ensure the construction progress on site; (2) Strong versatility and measurement accuracy High, easy to adjust, low cost, easy to install.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain the present invention, and are not intended to limit the present invention.

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the anchor plate center positioning device includes a positioning disk 2 coaxially arranged on the anchor plate 1. The center of 2 is provided with a measuring prism 3 used in conjunction with a precision total station; in this embodiment, the specific connection structure between the measuring prism 3 and the positioning disk 2 includes: a center is provided at the rear end of the measuring prism 3 Bolt 4, the central bolt 4 is threadedly connected with a locking nut 5 after passing through the center of the positioning disc 2, and the locking nut 5 cooperates with the central bolt 4 to detachably install and fix the measuring prism 3 on the positioning disc 2 , the above-mentioned connection structure is simple, and the disassembly, assembly and maintenance are convenient; in this embodiment, the diameter of the positioning disc 2 is 0.5 mm smaller than the diameter of the anchor pad 1, which is convenient for the positioning disc to be quickly installed on the anchor pad, and it is not easy to install. card slot;

When installing, first pass the central bolt 4 at the rear end of the measuring prism 3 from the center of the positioning disc 2, and then tighten the locking nut 5 on the central bolt 4, so as to detachably install and fix the measuring prism 3 on the positioning plate 2. On the disk 2, then place the positioning disk 2 in the slot at the rear end of the anchor plate 4. At this time, the measuring prism 3 is exactly perpendicular to the anchor plate 1 and on the central axis of the anchor plate 1. When using , Using a precision total station to directly measure the prism at a fixed position, the position of the central axis of the anchor pad can be easily and accurately determined, without the need to manually find the axis point, which reduces errors, ensures the installation accuracy of the anchor pad, and improves the construction efficiency.

The advantages of the utility model are: (1) It is convenient to quickly and accurately locate the central axis of the anchor pad, and by directly measuring the prism with a precision total station at a fixed position, the position of the central axis of the anchor pad can be directly determined, without the need for artificial Finding the axis point can avoid man-made measurement errors, minimize the measurement errors, improve the installation accuracy and construction efficiency of the anchor pad, and ensure the construction progress on site; (2) Strong versatility, high measurement accuracy, convenient adjustment, low cost, Easy to install.
