Description

Technical Field

[0001] The utility model belongs to the technical field of filling and supporting empty tunnels, and in particular relates to a quick-fixing template for a filling support mold bag. Background Art

[0002] The filling support technology for passing empty lanes is a new type of empty lane passing technology in recent years. Compared with the traditional empty lane passing method, it has the characteristics of high support strength and large roof control area. Compared with the filling of the entire empty lane, it has the characteristics of small filling volume, short construction period, simple construction process and high construction efficiency. When using filling support for passing empty lanes, in order to ensure that the support does not tilt and fall under the support pressure and can effectively support the roof, the pillars must be vertical and not bulge during the filling process. The filling pillar fixed template is required to fix the filling pillar mold bag. The initial method was to press a long wooden board around the filling pillar mold bag and use 8# iron wire to wrap and fix it. Since the wooden board is too long, it is not conducive to transportation down the mine, so the length of the wooden board is controlled, and the heights of different empty lanes are inconsistent, and the wooden boards cannot be connected, resulting in the length of the wooden board not matching the height of the empty lane. In addition, the method of manually wrapping the iron wire is time-consuming and labor-intensive, resulting in a large amount of construction work for fixing the filling pillar mold bag and low construction efficiency. Therefore, a quick-fixing template for filling a pillar mold bag is designed to simplify the mold bag fixing process, and the template can be recycled. Utility Model Content

[0006] Furthermore, the two ends of the binding belt are fixed by a clamping buckle, and a binding belt channel running through the front and back is constructed in the clamping buckle, and the binding belt channel includes a fixed inclined surface and an opposite movable inclined surface, and the sliding block where the movable inclined surface is located is connected to the screw on the clamping buckle, and the screw is screwed with the clamping buckle thread, one end of the screw is exposed, and the other end is rotatably connected to the sliding block; the two ends of the binding belt pass through the two ends of the binding belt channel respectively, and the screw pushes the sliding block so that the movable inclined surface and the fixed inclined surface press the binding belt tightly.

[0007] Furthermore, anti-slip grooves are provided on the movable inclined surface.

[0008] Furthermore, the support rod is a square steel tube.

[0009] Furthermore, a plurality of supporting bodies are evenly distributed around the filling pillar mold bag.

[0010] Compared with the prior art, the advantages of the present invention are:
