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

[0047] 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.

[0048] 2. See figure 2 , Figure 1 is the front view of the hanging device, Figure 2 is its top view, in wh...

Abstract

A temporary support hanging device, the invention relates to support equipment for tunnel construction, it includes a hanging device and an extension bolt, the hanging device is composed of a columnar member with a screw hole in the center and a circular ring member The combined parts that are concentrically fixed are combined with the flat plate with lifting rings and hooks on it. The extension bolt is composed of a columnar member with a longitudinal screw hole at one end and a bolt at the other end. The hanging device passes through the columnar member during work. The screw holes of the anchor bolts or the extension bolts fixed on the anchor bolts are fixed on the bottom of the roof, and then the front beam is hung by the lifting ring and the hook to support the roof. The invention has the advantages of simple structure, easy manufacture, and low investment. Less, easy to operate, high strength, strong adaptability to uneven roofs and resistance to gun collapse.

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 formula 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 ...
