Abstract
The utility model relates to an anchoring-bolt for support of mines, and the aim of the anchoring-bolt mainly made of plastic materials is to replace the anchoring-bolt made of metals and reduce production cost. The utility model comprises an outer expanding body (2) made of plastic, and a conical body threaded rod (3). One end of the conical body threaded rod (3) is provided with a plastic conical body (4) hot cast. The utility model has low production cost, the anchoring force of the utility model conforms to the national standard, the anchoring-bolt is especially suitable for the support of mine, and long-term use of the anchoring-bolt can observably enhance economical benefits.
Description
The utility model relates to a kind of mine support anchor pole.
In recent years, the novel support material pipe seam anchor bar of the many employings of shaft and drift supporting anchor pole, mine safety and economic benefit are obviously improved, yet pipe seam anchor bar all adopts the metal material manufacturing, along with improving constantly of price of steel product, the price of pipe seam anchor bar also goes up thereupon, causes mine production costs to increase, and economic benefit descends.
It is main material with the plastic material that the purpose of this utility model is to provide a kind of, the plastic expansion anchor metal that anchored force is big.
The purpose of this utility model can realize by following measure:
A kind of plastic expansion anchor metal comprises outer expander (2), conical screw (3), pallet (5), it is characterized in that outer expander (2) is made of plastic, and its outside has several flanges and axial expansion slit, center that one bellmouth that connects is arranged; Cone screw rod (3) one end external surface hot-cast one plastic cone bodies (4), and fixing with baffle ring (1); Cone screw rod (3) is contained in the bellmouth of outer expander (2), makes the plastic cone body (4) of one end contact other end tray (5) with outer expander (2).
The utility model low cost of manufacture, anchored force meet national standard, and antistatic, anti-fire-retardant requirement all meets ministry standard, and long-term use can significantly improve economic benefit.
Fig. 1 is a structure chart of the present utility model.
Be described in further detail enforcement of the present utility model below in conjunction with accompanying drawing:
According to shown in Figure 1, the utility model comprises outer expander (2), cone screw rod (3), pallet (5).Outer expander (2) is made of plastic, and external surface is more coarse, and several flanges and expansion slit are arranged, and there is a ganoid bellmouth at its center; Cone screw rod (3) is used the metal manufacturing, a plastic cone body of one end hot-cast (4), and fixing with baffle ring (1); Bellmouth with cone screw rod (3) the outer expander of threading (2) makes plastic cone body (4) tightly contact with outer expander (2), loads onto pallet (5) and nut (6) at the other end.
