Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and more specifically to a simple device for quantitative measurement of the angular offset of an I-beam frame canopy. Background Technology

[0002] Stable support in mining roadways is a prerequisite for ensuring safe production in coal mine working faces. Due to mine development plans, some mining roadways inevitably need to be located under goaf areas, often requiring passive support using I-beam frame canopies. Roadway excavation and face mining cause stress changes around the roadway, leading to deformation of the surrounding rock and causing roadway side convergence. This, in turn, causes the offset of support structures such as canopy legs. Accurate measurement of roadway deformation is crucial for adjusting roadway support schemes and optimizing support structures. Existing schemes lack direct monitoring of canopy leg offset, generally relying on optical methods such as total stations for measurement. These methods cannot achieve quantitative and continuous observation of canopy leg offset angles and are susceptible to human error, leading to discrepancies between measurement results and actual field conditions.

[0003] Therefore, how to provide a simple device for quantitative measurement of the angle deviation of I-beam sheds that can continuously measure the angle deviation is one of the technical problems that urgently need to be solved in this field. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A simple device for quantitative measurement of the angular offset of an I-beam frame shed includes: a sleeve, a rod, and a clamp; both ends of the rod are slidably connected to the sleeve; the clamp is provided at the end of the sleeve away from the rod; a liquid storage chamber is provided inside the rod; a colored liquid is provided in the liquid storage chamber; graduations are provided on the outer surface of the rod; and the rod is made of transparent material.

[0007] Preferably, the sleeve has a groove inside that is adapted to the rod; the rod is inserted into the groove.

[0008] Preferably, a spring is provided inside the slide groove; one end of the spring abuts against one end of the rod, and the other end of the spring abuts against the bottom wall of the slide groove.

[0009] Preferably, the sleeve is movably connected to the corresponding clamp via a pin.

[0010] Preferably, the clamp has a clamping groove.

Furthermore, through simple calculation, the offset angle of the I-beam steel frame support leg can be obtained, thereby helping tunnel workers to observe and adjust tunnel support measures in a timely manner.

[0014] 2) This utility model can accurately display the offset angle of the I-beam frame canopy legs, and can also significantly reduce the workload of installing roadway measuring devices, providing a basis for roadway workers to understand roadway deformation and further optimize support measures.

[0024] Reference Figure 1-6As shown, this utility model discloses a simple device for quantitative measurement of the angular deviation of an I-beam frame shed, comprising: a sleeve 1, a rod 2, and clamps 3; both ends of the rod 2 are slidably connected to the sleeve 1; a clamp 3 is provided at the end of the sleeve 1 away from the rod 2; a liquid storage chamber is provided inside the rod 2; the liquid storage chamber is filled with a colored liquid; the liquid volume is half the volume of the liquid storage chamber; graduations 4 are provided on the outer surface of the rod 2; the rod 2 is made of transparent acrylic material; in use, the two clamps 3 are respectively fixed and clamped to the top by bolts. On the free-floating flange of the I-beam, the sleeve 1 is connected to the clamp, and the two ends of the rod 2 are inserted into the corresponding sleeve 1 to complete the installation of the measuring device. After the device is installed, the height of the liquid level on both sides inside the rod 2 is recorded, and the tilt angle of the rod is calculated using the formula. When the legs of the I-beam frame shift, the liquid level height will also change accordingly, and the tilt angle of the rod will be calculated again using the formula. The difference between the two calculations gives the offset angle of the I-beam frame legs, thus realizing the continuous measurement of the offset angle of the I-beam frame.
