Description

Technical Field

[0001] The utility model relates to the technical field of coal mine measurement, in particular to a line-laying and positioning device for coal mine measurement. Background Art

[0002] The layout and positioning equipment for coal mine surveying is used in the surveying work carried out during mine construction and mining, including surveying and mapping work in planning and design, exploration and construction, production and operation management, and mine abandonment, to make corresponding preparations for the use and exploration of mines.

[0003] After searching, a kind of laying-out and positioning equipment for coal mine measurement with announcement number CN216243123U belongs to the field of coal mine measurement. A kind of laying-out and positioning equipment for coal mine measurement, including a lower box body, the upper end of the lower box body is plugged with an upper box body, the inner cavity of the lower box body is provided with a supporting plate matching with it, the lower end of the inner cavity of the lower box body and the lower end surface of the supporting plate are connected and fixed by a telescopic rod, the upper end of the supporting plate is provided with a positioning instrument body, the front and rear sides of the upper end of the upper box body are rotatably installed with a cover plate, and the lower box body and the right end of the upper box body are respectively rotatably and fixed with a first threaded sleeve and a first threaded rod rotatably connected to each other by threads. The utility model improves the protection effect of the internal structure such as the positioning instrument body.

[0004] Based on the above patent, the height of the upper box can be adjusted by the first threaded sleeve and the first threaded rod, and then the internal structure such as the locator body can be surrounded by the lower box and the cover plate, so that the storage of the structure can be completed and the protection effect of the structure can be improved. The position of the locator body can be adjusted by the lead screw and the threaded block. Compared with the original device using multiple structures such as the connecting rod, the movable bearing seat, the lead screw, the large pulley, the bag, the small pulley and the handle, the device is more convenient to operate and can avoid collision with the human body and other external structures. The locator body can be installed and disassembled at the upper end of the connecting seat by the second threaded sleeve and the second threaded rod. At the same time, the prism-shaped plug block and the prism-shaped slot can limit the movement direction of the locator body to ensure the fixing effect between the structures. However, when the device is used, when the locator is finely adjusted, the locator is only adjusted horizontally, resulting in the inflexible adjustment of the device when the detail adjustment is performed. The inflexible adjustment of the locator will affect the accuracy and precision of the measurement, resulting in an increase in the error of the measurement data, thereby affecting the accuracy of mine planning and construction.
