Abstract
The utility model relates to a tension anchoring bolt used for suspended ceiling in mine tunnels to prevent top rocks from falling off and collapsing. Screw nuts are screwed in screw rods and sheathed with washers, and then the screw nuts with the washers are sheathed with expansion rings in turn. Expansion blocks are respectively arranged between two expansion rings of the washers and the screw nuts, and the conical surfaces of the expansion rings are attached to the conical surfaces of the expansion blocks. The utility model has simple structure, reliable corrosion resistance, high durability, high tensile strength, repeated recovery and utilization, low consumption and convenient installation and disassembly, and a composite anchoring bolt above two stage can be utilized for fastening rock layers with special structure.
Description
A kind of Tension anchoring-bolt is used for the furred ceiling of mining tunnel, prevents that the top stone from coming off and caving in.
Before the utility model was made, the general employing of the furred ceiling of mining tunnel solidified the formula anchor pole, solidifies the formula anchor pole by screw rod, the cement cushion rubber is formed, and cover cement cushion rubber on the screw rod is placed in the water after the short time soaks, withstand cement film, fixedly rock pore with a sleeve pipe then.This structural anchor bar coagulates in rock pore, can not take out repeatedly and use, can only use once, owing to can not reclaim so waste of material is very big, and in installation process, effort, labour intensity is big, causes coming off of quick hardening cement easily, causes solidifying bad, and tensile strength is low.
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple in structure, easy to use, and labour intensity is low, can reclaim use repeatedly, the Tension anchoring-bolt that tensile strength is high.
The main solution of the utility model Tension anchoring-bolt is to realize like this, it mainly is made up of screw rod, nut, piston ring, the piece that rises, packing ring, nut is screwed into screw rod, packing ring packs into screw rod near nut, four piston rings, packing rings pack into screw rod successively, and the nut of screwing on again is equipped with the piece that rises respectively between piston ring, the piston ring conical surface is affixed on the piece conical surface that rises, and puts rubber ring then.
Description of drawings:
Fig. 1 is the utility model Tension anchoring-bolt structural front view:
Fig. 2 is the utility model Tension anchoring-bolt A-A ' sectional view:
Embodiment during following the utility model Tension anchoring-bolt is incited somebody to action in conjunction with the accompanying drawings is further described:
Compared with the prior art the utility model has the following advantages: 1, simple in structure, in light weight, corrosion-resistant, frictional resistance is big; 2, dependable performance, durable in use, the tensile strength height; 3, can repeatedly reclaim use, the use value height, thus reduced consumption; 4, easy installation and removal, labour intensity is low, has improved productivity effect.
Claims (2)
1, a kind of Tension anchoring-bolt is made up of screw rod, it is characterized in that nut is screwed into screw rod cover upper gasket, piston ring, packing ring, nut, and the piece that rises is housed between piston ring, and the piston ring conical surface is affixed on the piece conical surface that rises, and puts rubber ring at last.
2, Tension anchoring-bolt according to claim 1 is characterized in that the described piece that rises forms by three.
