Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of downhole measurement equipment, and relates to a positioning support for downhole control measurement. Background Technology
[0002] In the process of measuring planar coordinates in underground roadways, traverse surveying is typically used to transfer the positions of control points to the vicinity of the required working face. Traditional traverse surveying involves placing traverse points on the roadway roof and setting up instruments and prism devices below the points for measurement. The drawback of this method is that when the wind speed in the underground roadway is high, the plumb line and plumb bob will swing, which will affect the accuracy of the traverse surveying and increase the time required to set up the instruments. In addition, after the use of underground scanners, it is also necessary to set up three-dimensional control points in the roadway. Therefore, in order to improve the accuracy of traverse surveying and three-dimensional control points, it is necessary to provide a positioning reflective support for underground control surveying to solve the above-mentioned technical problems. Utility Model Content
[0003] The purpose of this invention is to address the problems existing in the prior art by providing a positioning support for downhole control measurement. This solves the problem that when existing traverse measurement methods are used in roadways with high wind speeds, the plumb line and hammer ball will swing, which easily affects the accuracy of traverse measurement.
[0004] Therefore, the present invention adopts the following technical solution:
[0005] A positioning support for downhole control and measurement includes a positioning base plate, which is horizontally arranged with a positioning pile at the top center and several stabilizing columns at the bottom. The positioning pile is vertically arranged with a positioning reflector sleeved on its top. A lighting lamp is provided on the side of the positioning reflector and arranged parallel to it. Several screws are provided at the top and bottom of the positioning base plate, and the screws at the top of the positioning base plate are all provided with studs. The lighting lamp is sleeved on any one of the studs. The stabilizing columns are connected to the positioning base plate through the screws.
[0006] Furthermore, the positioning base plate is triangular in shape, and each of its apex corners is provided with a screw post.
[0007] Furthermore, both the positioning reflector and the lighting lamp are vertically arranged.
[0008] The beneficial effects of this utility model are as follows:
[0009] This invention eliminates the need for prism leveling and centering steps during traverse surveying, simplifies the measurement process, reduces the workload of surveyors and the impact of strong winds on measurement accuracy, and improves work efficiency. Furthermore, it enables rapid location of target points in dimly lit environments, facilitating smooth measurement operations. This invention is characterized by its compact structure and high practicality, making it suitable for downhole control surveying and the positioning of three-dimensional control points. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model.
[0011] In the diagram, 1-lighting lamp, 2-positioning stake, 3-positioning base plate, 4-stud, 5-screw, 6-stabilizing column, 7-bedrock, 8-positioning reflector. Detailed Implementation
[0012] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.
[0013] like Figure 1 As shown, a positioning support for downhole control measurement includes a positioning base plate 3, which is horizontally arranged. A positioning pile 2 is provided at the center of its top, and several stabilizing columns 6 are provided at its bottom. Specifically, the positioning base plate 3 is made of 0.8mm thick acrylic plate. The stabilizing columns 6 are inserted into the bedrock 7 and are made of stainless steel nails with a specification of KD8-30-35S8.
[0014] The positioning stake 2 is vertically set, and a positioning reflector 8 is sleeved on its top. The side of the positioning reflector 8 is provided with a lighting lamp 1 that is parallel to it, which is used to illuminate the positioning reflector 8. The positioning base plate 3 is triangular, and three screws 5 are provided at its top corner and bottom. The screws 5 at the top of the positioning base plate 3 are all provided with studs 4. The lighting lamp 1 is sleeved on top of any one of the studs 4. The stabilizing column 6 is connected to the positioning base plate 3 through the screws 5.
[0015] Both the positioning reflector 8 and the lighting lamp 1 are vertically arranged. The positioning reflector 8 is made of acrylic sheet, and both sides are covered with crosshairs and circular target lines to reflect the laser beam output by the total station. It can be aimed using the crosshairs to complete the coordinate measurement work.
[0016] When this invention is applied to conductor measurement, its usage process is as follows:
[0017] First, the stabilizing post 6 is driven into the bedrock 7 of the tunnel floor. The height of the stabilizing post 6 is adjusted so that the positioning base plate 3 is as horizontal as possible, serving as the forward sight reference point for the traverse. The total station is then placed on the traverse reference point. Next, the positioning base plate 3, the positioning reflector 8, and the bolt 5 are assembled onto the stabilizing post 6, serving as the forward and backward sight reference points. Then, the positioning reflector 8 is rotated so that it faces the total station. The lighting 1 is turned on, and the position is rotated until the light illuminates the reflective surface of the positioning reflector 8. The laser beam from the total station is reflected by the positioning reflector 8 and used to aim and measure along its crosshairs, thus completing the control traverse measurement.
[0018] This invention is also applied to trigonometric leveling and three-dimensional control point measurement, and its application process is the same as the method described above.
