Abstract
The utility model discloses an anchor bolt/anchor cable fall-off preventing frame which is composed of pothooks, supporting portions and a surround portion, wherein the pothooks, the supporting portion and the surround portion are connected in integrated mode. The surround portion surround portion is composed of spiral round rings which are sleeved on the tail end of an anchor bolt or an anchor cable, two ends of the surround portion extend to form the two symmetrical supporting portions, and the tail ends of the supporting portions are connected with the pothooks. When the anchor bolt/anchor cable fall-off preventing frame is used, the surround portion is sleeved on an anchor bolt nut or an anchor cable locking device, and the two pothooks are respectively hung on a top net. The anchor bolt/anchor cable fall-off preventing frame is simple in structure, effectively buffers acting force during breaking when the anchor bolt or the anchor cable is stressed, resolves the problem that the anchor bolt or the anchor cable which is stressed and broken can fall off and hurt people, achieves manufacture easiness and installation convenience under a well, and can be reused.
Description
Technical field
The utility model relates to the attached protective device of a kind of anchor pole or anchor cable, specifically is a kind of be used to be enclosed within anchor pole or anchor cable, prevents the protective frame that anchor pole or anchor cable come off.
Background technology
Mine bolt or anchor cable are applied to stope drift active workings, soft-rock tunnel, fragmentation or the compound roof tunnel and work plane open-off cut and the large-section underground that influenced by dynamic pressure.Extension along with the depth of excavation; Big buried depth isolated island driving, back production, installed surface increase gradually, and the phenomenon that exploitation dynamic pressure district causes anchor pole or anchor cable pressurized to break happens occasionally, and anchor pole or the anchor cable pressurized strength that breaks is bigger; Can reach 15t respectively, more than the 30t, cause very big hidden danger to safety in production.
For guaranteeing job safety, after part colliery two 10# galvanized wires of use twined outside anchor cable lockset or anchor nut and are no less than two circles, 4 of right-angled intersections were bundled on the top group wire lath.The phenomenon that this method has avoided anchor pole that pressurized breaks or anchor cable to come off and hurt sb.'s feelings has to a certain extent been alleviated the pressure of safety work.But this method operation time spent is longer, has influenced drivage efficiency.Simultaneously, the insufficient strength of 10# galvanized wire, safe pressure is still very big.
Summary of the invention
The purpose of the utility model provides a kind of anchor pole/rope protective frame that comes off, to reach the break effect of strength of buffering anchor cable or anchor pole pressurized.
Anchor pole/the rope of the utility model come off hook that protective frame connects by one, support portion and constitute around portion; Said is to be enclosed within the terminal spiral annulus of anchor pole/rope around portion; Extend the support portion of two symmetries around the two ends of portion, the end of said support portion is connected with hook.During use, be enclosed within on anchor nut or the anchor cable lockset around portion, two hooks are hung in the top on the net.
Usually, the opening of said hook is towards the outer end of support portion, is about to the terminal outwards crotch of support portion, and when such structure can guarantee that anchor pole or anchor cable are stressed, protective frame should not be from pushing up online unhook.
Wherein, said have at least two spiral annulus around portion, and the angle between two support portions is 60 °-90 °.
Preferably, when being used for anchor cable, the angle between said two support portions is 90 °.When being used for anchor pole, the angle between two support portions is 62 °.
This anchor pole or the anchor cable protective frame that comes off, manufacturing process simply saves time, and can recycle, and has reached the break effect of strength of buffering anchor cable or anchor pole pressurized.
Anchor pole/the rope of the utility model protective frame that comes off is simple in structure, and active force when effectively having cushioned anchor pole or anchor cable pressurized and breaking has solved the phenomenon that anchor pole that pressurized breaks or anchor cable come off and hurt sb.'s feelings.
Anchor pole/the rope of the utility model protective frame that comes off is made easily, and the down-hole installation exercise is convenient, and can recycle and reuse, saving of labor, laborsaving, economical, safe and efficient.

The specific embodiment
Embodiment 1
The protective frame 1 of coming off anchor pole/rope adopts the 6# round steel to make, and its structure is as shown in Figure 1, comprises hook 11, support portion 13 and around portion 12.Wherein around portion 12 be around two spiral annulus, extend support portion 13 around the two ends of portion 12, the angle between the support portion 13 is 90 °, the end of support portion 13 go out to form hook 11 to excurvation.
During use, anchor cable 6 is installed in the anchor hole, tray 3, spherical washer 4 and lockset 5 successively on the anchor cable 6 that anchor hole exposes outside, anchor cable 6 is fixing.With anchor pole/rope being enclosed within on the anchor cable 6 of protective frame 1 that come off around portion 12, block lockset 5, hook 11 hangs on the top net 2 on anchor cable 6 both sides, and is as shown in Figure 2.
Embodiment 2
Anchor pole/rope comes off the structure of protective frame 1 with embodiment 1, and difference only is that the angle between the support portion 13 is 62 °, and its structure is as shown in Figure 3.
During use, anchor pole 10 is installed in the anchor hole, on the anchor pole 10 that anchor hole exposes outside successively tray 3, spherical washer 4, let and press pipe 7, packing ring 8 and nut 9, anchor pole 10 is fixing.With anchor pole/rope being enclosed within on the anchor pole 10 of protective frame 1 that come off around portion 12, block nut 9, hook 11 hangs on the top net 2 on anchor pole 10 both sides, and is as shown in Figure 4.
Claims (6)
