Abstract
The utility model discloses an anchor cable jacket and particularly discloses an anchor cable jacket capable of buffering when an anchor cable breaks. The anchor cable jacket comprises a sleeve and a protective wire rope, wherein a connecting plate is arranged at the front end of the sleeve, a minipore is formed in the connecting plate, metal hooks are respectively connected and fixed at the two ends of the protective wire rope, and the protective wire rope penetrates through the minipore of the connecting plate. The sleeve of the anchor cable jacket is sleeved on a tunnel anchor cable, and the two metal hooks are hanged on steel bands at the two sides. The anchor cable jacket is a simple device and can move with the mining of the tunnel. Wire rope cards are arranged at the end parts of the protective wire rope, and the protective wire rope is connected with the metal hooks through the wire rope cards. According to the anchor cable jacket disclosed by the utility model, the jacket is installed on the anchor cable, the sleeve sleeved at the outside of the anchor cable buffers the anchor cable when the anchor cable suddenly breaks to reduce the accidental injury degree to the minimum, and the device is simple in structure, convenient to operate, durable and can be recycled.
Description
Technical field
The utility model relates to the anchor cable protector in the coal mine roadway, and this device can play cushioning effect when anchor rope breakage.
Background technology
Bolting with wire mesh brings great convenience to colliery roadway support, but because the disconnected anchor cable accidents of cause specific such as periodic weighting, roof pressure are large, anchor cable quality also happen occasionally, sometimes work is damaged.Therefore, be necessary for anchor cable protector is set, play cushioning effect, the impact that brings effectively to reduce suddenly fracture of anchor cable, thus avoid disconnected anchor cable accident to hurt sb.'s feelings.
Summary of the invention
Technical scheme to be solved in the utility model provides a kind of anchor cable sheath that can play cushioning effect when anchor rope breakage.
For solving the problems of the technologies described above, a kind of anchor cable sheath of the utility model comprises sleeve pipe and steel wire protective rope, the sleeve pipe front end is provided with junction plate, have aperture on the junction plate, the two ends of steel wire protective rope are fixedly connected with respectively metal hook, and the steel wire protective rope passes from the aperture of junction plate.On tunnel anchor cable/rod, two metal hooks hang on the steel band of both sides with the casing pipe sleeve of anchor cable sheath.This is an easy device, can move along with adopting of tunnel.
Steel wire protective rope end is provided with wire line shoe, is connected with metal hook by this wire line shoe.Wire line shoe is used for regulating the length of wire rope.
The utility model adopts and installs sheath additional at anchor cable, when anchor cable ruptures suddenly, is enclosed within the outer sleeve pipe of anchor cable and can plays cushioning effect to anchor cable, can well unload the huge impulse force that suddenly fracture of anchor cable brings, and makes the degree of unexpected injury be reduced to minimum.Secondly, this apparatus structure is simple, and is easy to operate, durable in use, can also recycle.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the structure of the utility model anchor cable sheath and the schematic diagram when using.
Among the figure, 1-sleeve pipe, 2-steel wire protective rope, 3-junction plate, 4-metal hook, 5-wire line shoe, 6-top board, 7-anchor cable, 8-anchor pole, 9-steel band.
The specific embodiment
As shown in Figure 1, a kind of anchor cable sheath comprises sleeve pipe 1 and steel wire protective rope 2, and sleeve pipe 1 front end is provided with junction plate 3, has aperture on the junction plate 3, and the two ends of steel wire protective rope 2 are fixedly connected with respectively metal hook 4, and steel wire protective rope 2 passes from the aperture of junction plate 3.
Steel wire protective rope 2 ends are provided with wire line shoe 5, are connected with metal hook 4 by this wire line shoe 5.
The utility model provides a kind of concrete preparation method.Sleeve pipe 1 adopts 25.5cm long, and internal diameter is the steel pipe manufacturing of 2cm, with the 8mm wire rope of a long 100cm as steel wire protective rope 2.Steel pipe one end is forged into tabular as junction plate 3 through high-temperature heating, open the circular hole of a 10mm at junction plate 3, wire rope is passed from circular hole, the end that steel wire is strong is fixing with 8mm wire line shoe 5, and fixing metal hook 4.The pull-off force minimum of 8mm wire rope is 31200 Ns, and maximum is 42900 Ns.The bearing capacity minimum of metal hook 4 is 32000 Ns, and maximum is 43000 Ns.
During roadway support, squeeze into anchor cable 7 and anchor pole 8 at top board 6, the sleeve pipe 1 of anchor cable sheath is enclosed within on the tunnel anchor cable/rod 7, two metal hooks 4 hang on the both sides steel band 9.
