Description

Novel front canopy lifting ring for mine

Technical Field

The utility model relates to a mine support technical field, more specifically relates to a mine is with novel forestope rings.

Background

The forepoling beam is a device for temporarily supporting a coal mine underground tunneling working face, is generally used at the top of a mine tunnel, an anchor rod is driven into the top of the mine tunnel, then the hoisting rings of the forepoling beam are in threaded connection with the anchor rod, and then the anchor rod penetrates through the hoisting rings of a plurality of forepoling beams.

At present, most mines generally use the hoisting ring of the front canopy as a single hoisting ring, the hoisting ring is positioned under an anchor rod, the use is difficult and is not practical, and the hoisting ring of the front canopy obstructs the supporting operation due to small ground clearance in underground construction, so that the effect of the front canopy is extremely small, the danger in the supporting operation is increased, and meanwhile, the fine adjustment space of the existing hoisting ring is small when the existing hoisting ring meets a slope.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving in the background and present most mine and generally use the rings of forepoling beam for single rings, use the difficulty, and do not fit the reality, not only impracticable, because the clearance is little apart from the ground when the underground construction moreover, often because the rings of forepoling beam have obstructed the operation of strutting, so the effect of forepoling beam is minimum, and increased the danger when strutting the operation, current rings are when meetting the slope simultaneously, finely tune the problem that the space is little, thereby provide a mine with novel forepoling beam rings.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a mine is with novel forestope rings, includes top stock iron tray, top stock iron tray lower extreme integration is provided with top stock iron tray nut, top stock iron tray nut other end threaded connection has the screw anchor pole, screw anchor pole other end threaded connection has the stock nut, stock nut other end threaded connection has the forestope rings, all run through in the forestope rings and be provided with the forestope.

Preferably, the front cantilever hoisting ring is made of a phi 18 anchor rod and is in a convex shape.

Preferably, two ring frames are welded at two ends of each front canopy lifting ring, each ring frame is made of a phi 18 anchor rod and is arranged in a splayed manner, and the front canopy penetrates through the two ring frames.

Preferably, the front canopy is a 3-inch steel pipe front canopy.

Preferably, the number of the front cantilever hoisting rings is a plurality, and the front cantilever hoisting rings are uniformly fixed to the top of the mine tunnel through the anchor rod iron trays at equal intervals.

The utility model provides a mine is with novel forestope rings has following beneficial effect:

1. the novel front canopy lifting ring for the mine is provided with the front canopy lifting ring, the front canopy lifting ring is a front canopy lifting ring made of phi 18 anchor rods and is in a convex shape, two ring frames are welded at two ends of the front canopy lifting ring and are also made of phi 18 anchor rods, the two ring frames are arranged in a splayed mode, the front canopy penetrates through the two ring frames, when workers carry out supporting operation, the front canopy is adjusted to the front canopy lifting ring staggered with the threaded anchor rods, and compared with the existing single lifting ring, the lifting ring with the structure can utilize part of height of the threaded anchor rods, ground clearance is improved, supporting operation is enabled to be carried out smoothly, safety of the workers is guaranteed, and safety during heading operation is improved.

2. This kind of mine is provided with novel forestope rings, and the interlock that the stock nut utilized the screw thread can be adjusted the height of forestope rings for when less domatic use, more flexibility.
