Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of underground mine construction equipment, and in particular relates to a reusable bracket used in underground mines. Background Art
[0002] Underground transport tunnels typically use wooden planks and gray bricks to construct temporary storage bases for materials such as cement and accelerators. Underground working environments are typically poorly ventilated. If a construction site requires a large volume of materials and requires a large number of wooden planks, this can pose a fire hazard. Using a single-piece cement-cast storage base would be difficult to move flexibly and would require long-term storage at the construction site, resulting in poor appearance and hindering standardized on-site construction. Summary of the Invention
[0003] The purpose of the utility model is to provide a reusable bracket for use in mines, which can be flexibly carried on construction sites and does not pose any fire hazard.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A reusable support for use in underground mines, comprising at least three support frames arranged side by side, the support frames comprising at least two steel legs arranged side by side, two adjacent legs being fixedly connected by a steel tie rod, and the top ends of all the support frames being connected by a receiving frame; the receiving frame comprising steel cross bars arranged side by side, the number of which is the same as the number of legs in one support frame, two adjacent cross bars being connected by a plurality of steel cross bars, the same cross bar in the receiving frame being fixedly connected to the top ends of all legs with the same serial number and arranged in the same direction in all the support frames, and the legs being connected to the cross bars fixed to the legs by two leg oblique tie bars.
[0006] The reusable bracket of the utility model is a steel bracket with a simple structure, easy installation, flexible movement and reuse. There is no fire hazard when a large amount of construction materials such as cement are placed. It can replace the temporary storage base for storing materials in mines.

[0012] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.
[0013] See Figures 1 to 4 The reusable bracket of the present invention includes at least three support frames arranged side by side, and the support frame includes at least two steel legs 2 arranged side by side, two adjacent legs 2 are fixedly connected by a steel pull rod 5, and the top ends of all the support frames are connected by a receiving frame; the receiving frame includes steel cross bars 1 arranged side by side, the number of which is the same as the number of legs 2 in one support frame, and two adjacent cross bars 1 are connected by multiple steel cross bars 4. The same cross bar 1 in the receiving frame is fixedly connected to the top ends of all legs 2 with the same serial number and arranged in the same direction in all the support frames, and the legs 2 are also connected to the cross bars 1 fixed to the legs 2 through two leg oblique tie bars 3.
[0014] To ensure uniform load-bearing of the reusable bracket of the present invention, the distance between two adjacent cross bars 1 is equal, the distance between two adjacent cross bars 4 is equal, and the two leg diagonal tie bars 3 of the same leg 2 are symmetrically arranged along the axis of the leg 2.
[0015] The crossbar 1, the supporting leg 2, the tie rod 5, the supporting leg oblique tie rod 3 and the crosspiece 4 are all cylindrical; the outer diameters of the crossbar 1, the supporting leg 2 and the tie rod 5 are equal, and the outer diameters of the supporting leg oblique tie rod 3 and the crosspiece 4 are equal.
[0016] A concrete platform is poured in a designated material placement area under the mine, and then the reusable bracket of the utility model is transported as a whole to the mine, placed on the concrete platform, and firmly installed.
