Problems solved by technology

[0003] 1. The bearing nut is fixed on the outer surface of the tubular member, the fixed area is small, the strength is low, and the purpose of controlling the roof cannot be achieved
[0004] 2. Poor stability
[0005] 3. When the roof is concave, because the hanging point is not adjustable, the front probe beam cannot be put on, and the function of supporting the roof cannot be realized.
[0006] 4. Inconvenient operation, time-consuming and labor-intensive

Embodiment Construction

[0048] 1. See figure 1 , the invention includes a bearing column, a circular ring and a plane plate with through holes on it. Figure 1 is the front view of the hanging device, Figure 2 is the top view, in which the circular ring (4) is fixed concentrically with the bearing column (3), and the plane plate (7) is matched with the bearing column through the rectangular groove on its upper part and For fixed connection, circular through holes (2) are arranged on the plane plates on both sides and below of the bearing column as suspension rings. Figure 3 is a front view of its working state. In the figure, the hanging device cooperates with the external bolt of the anchor rod through the screw hole (5) on the bearing column, and the circular ring on the upper part of the bearing column cooperates with the fixing nut of the anchor rod, and is fixed on the top plate under.

[0049] 2. See figure 2 , Figure 1 is the front view of the hanging device, Figure 2 is its top view, in wh...

Abstract

The invention discloses a hanging device for temporary support, and relates to shoring equipment for laneway construction. The hanging device for the temporary support comprises a hanging device and a lengthened bolt, wherein the hanging device is formed by matching and fixedly connecting a combined component with a flat panel; the combined component is formed by concentrically fixedly connecting a columnar component provided with a central screw hole, with an annular component; the flat panel is provided with a hanging ring and a hanging hook; and the lengthened bolt is formed by a columnar component of which one end is provided with a longitudinal screw hole and the other end is provided with a bolt. During work, the hanging device is matched with an anchor bolt or the lengthened bolt fixed on the anchor bolt through the screw hole in the columnar component and is fixed below a top plate, and the hanging ring and the hanging hook are used for hanging a front probe beam to shore the top plate. The hanging device for the temporary support has the advantages of simple structure, simplicity in manufacture, small investment, convenience for operation, high strength, strong adaptability to an uneven top plate, cannon collapse resistance and the like.

Description

technical field [0001] The invention relates to support equipment for underground bolt support roadway construction. Background technique [0002] At present, more than 90% of shaft and roadway construction at home and abroad are supported by anchor shotcrete technology, and most of the temporary support adopts the front-beam type support method. Connect a bearing nut to form a hanging device. In the working state, the bearing nut cooperates with the anchor bolt to fix the tubular member under the roof, and the tubular member cooperates with the front probe beam to hang the front probe beam under the roof to realize support. The role of the roof. But this front probe beam type temporary support hanger has following shortcoming: [0003] 1. The bearing nut is fixedly connected to the outer surface of the tubular member, the fixed area is small, the strength is low, and the purpose of controlling the roof cannot be achieved. [0004] 2. Poor stability. [0005] 3. When the...
