Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine production, in particular to a guide bracket for quickly fixing a total station and a system for determining a station moving coordinate position. Background Art

[0002] Total stations play a vital role in ensuring tunnel accuracy, improving production efficiency and ensuring safety. When the TBM moves forward, the total station will monitor the movement trend of the TBM shield in real time and match it with the local design trajectory, and display it in real time to guide the TBM excavation.

[0003] In coal mine production technology, the total station is fixed on the left rock wall of the tunnel to guide TBM excavation. However, during the excavation construction in the curved area, the fixing point of the total station needs to be frequently changed due to the influence of the curved tunnel. In the early stage of the curved tunnel construction, the existing technology uses an anchor drill to construct four anchors on the tunnel roof to fix the total station to solve the above problem, but the following problems still exist:

[0004] On the one hand, the coordinates of the total station after changing stations require high construction accuracy of the anchor rods, and the entire construction and installation time is relatively long; on the other hand, each station change will waste support materials. Utility Model Content

[0005] The utility model aims to provide a guide bracket for quickly fixing a total station and a system for determining the coordinate position of a moving station, so as to solve the problems of long construction time and high construction accuracy requirement for replacing the fixed position of the total station.

[0006] The utility model adopts the following technical scheme: a guide bracket for quickly fixing the total station, the guide bracket is fixed to the lower end of the existing permanent support anchor rod that has been anchored into the tunnel roof, the upper end of the permanent support anchor rod is anchored into the tunnel roof, and the lower end extends downward and is exposed in the tunnel;

[0007] The guide bracket includes:

[0008] The upper fixing plate is arranged horizontally, and its center position is fixedly connected to the lower end of the permanent support anchor rod;

[0009] The lower fixing plate is horizontally arranged and located below the upper fixing plate; the upper side of the lower fixing plate is used for placing the total station;

[0010] A plurality of vertical poles are arranged vertically, the upper ends of which are clamped on the upper fixing plate, and the lower ends of which are respectively fixedly connected to the upper side of the lower fixing plate, and then cooperate with the upper fixing plate and the lower fixing plate to form a frame;

[0011] Multiple fixing screws are arranged vertically around the edge of the lower fixing plate, with their upper ends resting on the tunnel roof and their lower ends extending downward and being clamped by the upper fixing plate; they are used to adjust the horizontal state of the lower fixing plate by adjusting the length of the fixing screws extending under the upper fixing plate, so that the lower fixing plate can carry the total station.

[0012] A system for determining the coordinate position of a station transfer, comprising:

[0013] Two guide brackets; fixed at a predetermined distance and respectively fixed to the lower ends of two permanent support anchor rods;

[0014] A front prism is placed in the inner cavity of the guide bracket at the front side;

[0015] A rear prism is placed in the inner cavity of the guide bracket at the rear side;

[0016] Among them, the rear prism is used to calibrate the coordinate position of the total station, and the front prism is used to obtain the coordinate position of the total station after moving.

[0017] The beneficial effects of the utility model are:

[0018] The utility model is simple and quick to use, and the time consumption of station change is shortened, and the manufacturing cost and maintenance cost are low;

[0019] The utility model directly uses permanent support anchor rods to avoid installing anchor rods again to fix the total station, and thus there is no problem of high construction precision requirements, because the prior art is to fix by installing four anchor rods, and these four anchor rods require the same height to ensure the level of the total station, so high precision is required, while the utility model directly uses permanent support anchor rods, and only uses one, but uses four fixing screws to adjust the length of the lower fixing plate to adjust the horizontal state of the lower fixing plate, so that the lower fixing plate carries the total station, thereby ensuring the level state of the total station. Therefore, the utility model has low precision requirements, directly uses permanent support anchor rods, and has a short construction time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The guide bracket includes: an upper fixing plate 20 , a lower fixing plate 21 , a plurality of vertical rods 23 , and a plurality of fixing screws 22 .

[0026] The upper fixing plate 20 is arranged horizontally, and the center position of the upper fixing plate 20 is fixedly connected to the lower end of the permanent support anchor rod 11; the lower fixing plate 21 is arranged horizontally, and the lower fixing plate 21 is located below the upper fixing plate 20; the upper side of the lower fixing plate 21 is used to place the total station.

[0027] Multiple vertical rods 23 are arranged vertically, and the upper ends of the multiple vertical rods 23 are clamped on the upper fixing plate 20, and the lower ends of the multiple vertical rods 23 are respectively fixedly connected to the upper side of the lower fixing plate 21, and then cooperate with the upper fixing plate 20 and the lower fixing plate 21 to form a frame.
