Description
Technical Field
The utility model relates to a bridge anchor backing plate location erection equipment technical field, concretely relates to anchor backing plate center positioning device.
Background
At present, during the installation, measurement and positioning of the suspension bridge anchor backing plate, the positioning of the anchor backing plate exceeds the design allowable range due to the influence of external environmental factors such as wind force and the like, and the construction efficiency is low. In order to enable the measurement accuracy to meet the requirement, the anchor backing plate must be adjusted repeatedly, but the mode that the posture of the anchor backing plate is adjusted by manually finding the central axis of the anchor backing plate in the construction process is complex, if each anchor backing plate is adjusted to the designed position and then fixed, a large amount of time is wasted, and the installation progress is influenced. Therefore, it is necessary to invent a positioning device, which changes the current situation of the influence of the traditional working mode on the construction efficiency and reduces the influence of the external factors on the observation accuracy to the minimum.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an anchor backing plate center positioning device convenient to fix a position out anchor backing plate the central axis fast, accurately.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the anchor backing plate center positioning device comprises a positioning disc coaxially arranged on an anchor backing plate, and a measuring prism matched with a precision total station for use is arranged in the center of the positioning disc.
Further, the anchor pad centering device of the preceding, wherein: the concrete connection structure between the measuring prism and the positioning disc comprises: the rear end of the measuring prism is provided with a central bolt, the central bolt penetrates out of the center of the positioning disc and then is in threaded connection with a locking nut, and the locking nut is matched with the central bolt to detachably mount and fix the measuring prism on the positioning disc.
Further, the anchor pad centering device of the preceding, wherein: the diameter of the positioning disc is 0.5mm smaller than that of the anchor backing plate.
Through the implementation of the above technical scheme, the beneficial effects of the utility model are that: (1) the central axis of the anchor backing plate can be conveniently and rapidly and accurately positioned, the position of the central axis of the anchor backing plate can be directly determined by directly measuring the prism by using a precise total station at a fixed position without manually finding an axis point, so that the manual measurement error can be avoided, the measurement error is reduced to the minimum, the mounting precision and the construction efficiency of the anchor backing plate are improved, and the on-site construction progress is guaranteed; (2) the device has the advantages of strong universality, high measurement precision, convenience in adjustment, low cost and convenience in installation.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1, 2, 3, 4 and 5, the anchor backing plate center positioning device includes a positioning disc 2 coaxially disposed on an anchor backing plate 1, and a measuring prism 3 used in cooperation with a precision total station is disposed at the center of the positioning disc 2; in the present embodiment, the specific connection structure between the measuring prism 3 and the positioning disk 2 includes: the rear end of the measuring prism 3 is provided with a central bolt 4, the central bolt 4 penetrates out of the center of the positioning disc 2 and then is in threaded connection with a locking nut 5, and the locking nut 5 is matched with the central bolt 4 to detachably mount and fix the measuring prism 3 on the positioning disc 2; in the embodiment, the diameter of the positioning disc 2 is 0.5mm smaller than that of the anchor backing plate 1, so that the positioning disc can be conveniently and quickly mounted on the anchor backing plate without clamping grooves during mounting;
during installation, firstly, the center bolt 4 at the rear end of the measuring prism 3 penetrates out from the center of the positioning disc 2, then the locking nut 5 is screwed on the center bolt 4, the measuring prism 3 is detachably installed and fixed on the positioning disc 2, then the positioning disc 2 is placed in the clamping groove at the rear end of the anchor backing plate 4, at the moment, the measuring prism 3 is exactly and accurately perpendicular to the anchor backing plate 1 and is on the central axis of the anchor backing plate 1, during use, the direct measuring prism is set with a precise total station at a fixed position, the central axis position of the anchor backing plate can be conveniently and precisely determined, artificial axis point finding is not needed, errors are reduced, the installation precision of the anchor backing plate is ensured, and meanwhile, the construction efficiency is improved.
The utility model has the advantages that: (1) the central axis of the anchor backing plate can be conveniently and rapidly and accurately positioned, the position of the central axis of the anchor backing plate can be directly determined by directly measuring the prism by using a precise total station at a fixed position without manually finding an axis point, so that the manual measurement error can be avoided, the measurement error is reduced to the minimum, the mounting precision and the construction efficiency of the anchor backing plate are improved, and the on-site construction progress is guaranteed; (2) the device has the advantages of strong universality, high measurement precision, convenience in adjustment, low cost and convenience in installation.
The above description is only a preferred example of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
