Abstract
The utility model discloses a nest type anchor cable, relates to a bird cage type anchor cable, and belongs to the technical field of mine support. The nest type anchor cable comprises a cable body, an anchor body and a support plate. The utility model is characterized in that a collar clamp and a limiting sleeve are arranged on the cable body, the collar clamp is positioned on the inner side of an outer-layer steel wire of the cable body and mounted on an inner-layer steel wire of the cable body, and the limiting sleeve is mounted on the outer side of the cable body. The utility model has the benefits that the diameter of the anchor cable is increased to be matched with the diameter of a drill hole, so that an anchoring agent is thoroughly stirred in the position of the anchor cable and the contact area of the anchor cable with the anchoring agent is enlarged; and the tail part of the stranded steel wire used for the anchor cable is treated by a certain method, so as to increase the diameter of the tail part of the cable body, increase the contact area of the tail part of the cable body with the anchoring agent to result in a large prestress, and achieve the effect of enhancing the anchoring force. The nest type anchor cable can support a mine roadway more firmly and stably.
Description
Technical field
The utility model belongs to the mine support technical field, relates to a kind of birdcage anchor cable.
Background technology
Anchor cable is made up of cable body, ground tackle and supporting plate etc., and cable body is general to be made with having certain crooked flexible steel strand.Being characterized in that anchorage depth is big, supporting capacity is high, can applying bigger pretightning force, thereby can obtain more satisfactory supporting effect, is one of the most reliable at present, the most effective a kind of supporting means.
When using the high-strength prestress anchor shaft anchor cable to carry out roadway support, anchor cable need be helped to set at back or two in the part tunnel, and anchor cable needs stretch-draw, with reach apply more high-prestressed.But find anchor cable in the The field process when being applied to certain prestressing force, anchor cable occurs being drawn loosening or phenomenon such as is pulled out.
At present, the kind of the anchor cable steel strand that the mine is commonly used is a lot, and China's prestressed concrete member, ground anchorage extensively adopt the steel strand of 1 * 7 strand of structure of steel wire and 1 * 19 strand of structure of steel wire.
Summary of the invention
The utility model purpose is to overcome The field process stream line when applying prestressing force, anchor cable occurs being drawn loosening or phenomenon such as is pulled out, provide a kind of increase itself and anchoring agent contact area, increase afterbody cable body diameter, strengthen the birdcage anchor cable of the contact area of afterbody cable body and anchoring agent.
The technical solution adopted in the utility model is:
A kind of bird's nest anchor cable comprises cable body, ground tackle and supporting plate, is characterized in being provided with on cable body clip and stop collar, and described clip is in the inside of cable body cover wire, and is loaded on the steel wire of cable body inside; Described stop collar is installed on the outside of cable body.
Described a kind of bird's nest anchor cable is characterized at the cable body length direction along anchor cable a clip being housed at least, adorns two stop collars on the two ends cable body of each clip at least.
A kind of bird's nest anchor cable that the utility model provides is compared with existing anchor cable, the beneficial effect that has is: by enlarging the anchor cable diameter itself and bore diameter are complementary, assurance anchoring agent is fully stirred at this position, increase itself and anchoring agent contact area, anchor cable takes certain measure to handle with the afterbody of steel strand after, increase afterbody cable body diameter, strengthen the contact area of afterbody cable body and anchoring agent, for obtaining bigger prestressing force, reach the effect that strengthens anchored force.For this reason, the utility model is firm more and stable for the mine laneway supporting.
Description of drawings
Fig. 1 is an anchor cable cable body mounting structure schematic diagram of the present utility model.
Fig. 2 is the utility model embodiment 1 generalized section.
Fig. 3 is the utility model embodiment 2 generalized sections.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, anchor cable cable body mounting structure schematic diagram of the present utility model.Stirring-head 2 places of keeping at a certain distance away at distance cable body 1 install clip 3 and stop collar 4 respectively, and described clip and is loaded on the steel wire of cable body inside in the cable body cover wire; Stop collar is installed on the outside of cable body.At the cable body length direction along anchor cable a plurality of clips can be housed, the two ends cable body of a clip is adorned two stop collars outward.Described clip is an annular element.Can directly use nut as clip.
As shown in Figure 2, be the steel strand generalized section of 1 * 7 strand of structure of steel wire of the utility model embodiment 1.Clip 3 is installed in the cable body cover wire on the steel wire with cable body inside.Its cable body inside has steel wire to pass clip 3.
As shown in Figure 3, be the steel strand generalized section of 1 * 19 strand of structure of steel wire of the utility model embodiment 2.Clip 3 is installed in the cable body cover wire on the steel wire with cable body inside.The inner wire of cable body is passed in the inside of clip 3.
More than because clip 3 is contained in the cable body cover wire, cause the cable body cover wire to be blown and constitute likeness in form birdcage shape.
When implementing the utility model, the steel strand steel wire is all opened, cover one clip in process wire; Then the steel strand steel wire is tightly wrapped again, a birdcage successfully is installed, put stop collar after keeping at a certain distance away.
Repeat above process, can on cable body, constitute a plurality of birdcages.
Claims (2)
1. a bird's nest anchor cable comprises cable body, ground tackle and supporting plate, it is characterized in that: be provided with clip and stop collar on cable body, described clip is in the inside of cable body cover wire, and is loaded on the steel wire of cable body inside; Described stop collar is installed on the outside of cable body.
2. according to the described a kind of bird's nest anchor cable of claim 1, it is characterized in that: at cable body length direction a clip is housed at least, adorns two stop collars on the two ends cable body of each clip at least along anchor cable.
