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 deformation of I-beam steel frame structures. 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 support frames. Roadway excavation and face mining cause stress changes around the roadway, leading to deformation of the surrounding rock, which in turn causes deformation of the support structure, such as the support frames. Accurate measurement of roadway deformation is crucial for adjusting roadway support schemes and optimizing support structures.

[0003] Existing methods mostly employ the cross-observation method or optical methods for measurement. The cross-observation method involves fixing wooden stakes or steel rods as measuring points on the roof, floor, and sides of the tunnel, then using measuring lines and tape measures for measurement—a rather cumbersome process. Optical methods utilize equipment such as total stations or laser rangefinders. These methods cannot achieve continuous real-time monitoring of tunnel surrounding rock deformation and are susceptible to human error, leading to discrepancies between the measured results and the actual site conditions. Furthermore, these methods are easily affected by tunnel construction, vehicle and pedestrian traffic, and other factors that can influence the measurement results.

[0004] Therefore, how to provide a simple device that can realize real-time monitoring of roadway deformation and quantitative measurement of deformation of I-beam steel frame canopy is one of the technical problems that urgently need to be solved in this field. Utility Model Content

[0005] In view of this, the present invention provides a simple device for quantitative measurement of deformation of I-beam steel frame sheds, with the aim of solving the problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A simple device for quantitative measurement of deformation of I-beam steel frame sheds includes: a marker, a sleeve, and two clamps; one end of the marker is slidably connected to the inside of the sleeve; the end of the marker away from the sleeve is connected to one of the clamps; the end of the sleeve away from the marker is connected to the other clamp; and the outer surface of the marker is provided with a scale.

[0008] Preferably, the clamp has a clamping groove.

[0009] Preferably, the marker is a cylindrical structure.

[0010] Preferably, the sleeve has a groove inside that is adapted to the marker; the marker is inserted into the groove.

[0011] Preferably, the marker and the sleeve are movably connected to the corresponding clamps via pins.

[0012] Compared with the prior art, this utility model has achieved the following technical effects: This utility model can not only accurately display the deformation of the I-beam frame, thereby realizing real-time monitoring of the deformation of the surrounding rock in the roadway, and thus providing a basis for roadway workers to understand the roadway deformation and further optimize support measures, but also significantly reduce the workload of roadway measuring device installation and effectively avoid errors generated during operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Reference Figure 1-5As shown, this utility model discloses a simple device for quantitative measurement of deformation of I-beam frame canopy, including: a marker 1, a sleeve 2, and two clamps 3; one end of the marker 1 is slidably connected to the inside of the sleeve 2; the end of the marker 1 away from the sleeve 2 is connected to one clamp 3; the end of the sleeve 2 away from the marker 1 is connected to the other clamp 3; the outer surface of the marker 1 is provided with a scale for easy reading, thereby facilitating continuous observation of the deformation of the roadway; in use, the two clamps 3 are fixedly clamped to the free side flanges of the top and side of the I-beam with bolts to complete the installation of the measuring device, and the original reading is recorded. When the I-beam deforms, the relative position of the marker 1 and the sleeve 2 changes, causing the current reading to differ from the original reading, thereby realizing the monitoring of the deformation of the I-beam frame canopy.

[0022] In this embodiment, the clamp 3 is provided with a clamping groove 4; when in use, the side flange of the I-beam is inserted into the clamping groove 4 and fixed with bolts, which can avoid drilling in the surrounding rock of the roadway and reduce the workload of the measurement device installation process.

[0023] In this embodiment, the marker 1 is a cylindrical structure.

[0024] In this embodiment, the casing 2 has a groove inside that matches the marker 1; the marker 1 is slidably inserted into the groove; during use, the marker 1 slides in the groove of the casing 2 as the surrounding rock of the roadway deforms, causing the relative position of the marker 1 and the casing 2 to change. Thus, the deformation of the surrounding rock of the roadway can be continuously observed through the scale on the marker 1, so that the roadway workers can adjust the roadway support in a timely manner according to the measurement data, thereby ensuring the safety and stability of the roadway during use.

[0025] In this embodiment, the marker 1 and the sleeve 2 are rotatably connected to the corresponding clamps 3 by pins, so that the marker 1 and the sleeve 2 have a large range of motion with the clamps 3, thereby more effectively obtaining the deformation of the scaffold.

[0026] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
