Description

Technical Field

[0001] The utility model relates to the technical field of mining engineering, in particular to a temporary support device for roadways in mining engineering. Background Technique

[0002] In mining engineering, the excavation of roadways is to facilitate the entry of personnel and equipment and the transportation of minerals. However, after the roadway is excavated, the surrounding rock mass loses its original balance state and is prone to deformation, collapse, etc., especially in some areas with complex geological conditions and poor rock stability. Therefore, it is necessary to temporarily support the roadway to ensure the safety of construction and the smooth progress of operations. Traditional wooden supports were once widely used, but the strength of wood is limited, it is easy to decay, and the support effect is unstable. Moreover, with the increase of mining depth and the expansion of roadway cross-section, wooden supports often cannot meet the requirements of support strength.

[0003] The prior art such as the utility model with the publication number of CN216240732U discloses a temporary support device for roadways in mining engineering. This patent adopts a temporary support device for roadways in mining engineering, including two support bottom plates. The top of the support bottom plates is fixedly connected with two left and right support columns through fixing bolts. A rotating member is fixedly connected between the adjacent support columns on the two support bottom plates. A locking mechanism is arranged inside the support bottom plates. The locking mechanism includes a through groove opened inside the support bottom plates, two sliding rails and a locking component. The two sliding rails are respectively located above and below the through groove. The utility model relates to the technical field of indicator lights. The wedge block of this temporary support device for roadways in mining engineering can rotate, so that the support bottom plates can be easily installed and adapted to the angle of the bend at the position of the roadway bend, and the position is fixed under the action of the first gear and the second gear of the locking mechanism, improving the universality of the device. Then, the support device is assembled through the installation component, thus facilitating the installation process of the support device, solving the problems that the temporary support device for roadways in mining engineering is inconvenient to install due to the narrow roadway space, and cannot be well adapted to the installation at the turning place of the roadway.

Even in the same mine roadway, the height and width of different regions in the mine cave may be inconsistent. When it is necessary to use support equipment, it is necessary to frequently replace support devices of different sizes, resulting in waste of replacement costs and adjustment time.
