Description
Technical Field
[0001] The utility model belongs to the technical field of underground mine measurement, in particular to an underground mine height measuring device. Background Art
[0002] Underground mine surveying is the comprehensive application of relevant knowledge from multiple disciplines such as surveying, geology, and mining to solve and deal with spatial geometry problems in various mining projects from ore bodies to surrounding rocks, from the ground to underground during mine construction and mining.
[0003] When measuring height underground in existing mines, it is usually necessary to use a tripod to support the measuring equipment. Since the ground in the mine is uneven, the tripod does not have the function of adjusting a single leg, so when in use, the measuring equipment is prone to tilt, which not only causes inaccurate measurements, but also the tilted support is prone to collapse, causing the measuring equipment to fall and be damaged. Therefore, we propose a height measuring device for underground mines. Utility Model Content
[0004] The purpose of the utility model is to provide a height measuring device for underground mines. By setting an adjustment component, specifically rotating a threaded ring to drive the threaded rod to move upward or downward, the length of the threaded rod on the tripod support frame can be adjusted individually, so that the height measuring equipment is in a relatively horizontal state, the support is more stable, and the tilting is reduced. It can not only improve the measurement effect, but also avoid collapse. It solves the problem that the tripod does not have the function of adjusting a single leg, so that the measuring equipment is easily tilted during use, which will not only cause inaccurate measurement problems.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a mine underground height measuring device, comprising a fixed plate, a height measuring device is fixedly connected to the top of the fixed plate, three grooves are opened at the bottom of the fixed plate, the three grooves are arranged in a circular array with the fixed plate as the center, the inner walls of the three grooves are rotatably connected to a triangular support frame through a rotating shaft, and an adjustment component is arranged at the bottom of the triangular support frame;
[0007] A fixing column is fixedly connected at the center of the bottom of the fixing plate, and the adjusting component includes a threaded rod, a limiting ring is fixedly connected to the top of the threaded rod, and a threaded ring is threadedly connected to the outer surface of the threaded rod. By setting the adjusting component, the length of the threaded rod on the tripod support frame can be adjusted individually, so that the height measuring device is in a relatively horizontal state, the support is more stable, and the tilting is reduced, which can not only improve the measurement effect but also avoid collapse.
[0008] Furthermore, a circular hole slide groove is provided at the bottom of the triangular support frame, and limiting grooves are provided on the front and back sides of the circular hole slide groove. The outer surface of the limiting ring is slidably connected to the inner wall of the circular hole slide groove, and the front and back sides of the limiting ring are fixedly connected to the limiting block, and the outer surface of the limiting block is slidably connected to the inner wall of the limiting groove. The top of the threaded ring contacts the bottom of the triangular support frame, and the top of the threaded rod penetrates the triangular support frame and extends to the inside of the circular hole slide groove. The threaded rod will drive the limiting block to slide in the limiting groove through the limiting ring, which is used to limit the threaded rod and make the threaded rod move in a straight line.
[0009] Furthermore, the front and back sides of the triangular support frame are provided with sliding grooves, the top of the inner wall of the threaded ring is provided with an annular groove, the inner wall of the annular groove is rotatably connected with a connecting ring, the top of the connecting ring is fixedly connected to the bottom of the triangular support frame, and the sliding ring will drive the slider to slide in the sliding groove through the fixed plate, and the triangular support frame is driven to move under the action of the slider.
