The specific embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is done further explain.
Fig. 1 and Fig. 2 show reeve a kind of embodiment of guider of the utility model U type anchor cable integral body; This guider comprises the connector 1 and drawing head 2 of mutual butt joint, and the traction end of drawing head 2 is provided with pulling rope 21, and the contoured surface of its traction end is a spherical; Also can drawing head 2 be designed to semielliptical shape or similar spherical structure such as tubaeform; Thereby can lower the resistance of drawing head 2 in the pre-buried pipe of U type, what assurance was reeved carries out smoothly, prevents the Carcel situation; Offer on the connector 1 and can supply that steel strand 4 pass and the through hole 11 consistent with steel strand 4 quantity in the anchor cable; Through hole 11 is according to the quantity and the arrangement customization processing of practice of construction stream line steel strand 4, and each through hole 11 space is arranged, is equipped with in each through hole 11 steel strand are fixed on the automatic lock assembly 3 in the through hole.During use; Every steel strand 4 in the anchor cable can through automatic lock assembly 3 respectively correspondence be fixed in the through hole 11; The drawing head 2 that docks with connector 1 through tractive again can pass the pre-buried pipe of U type with the anchor cable tractive, realizes having the integral body of bonding band isolation mount U type prestress anchorage cable to reeve, and can solve in the existing construction there being reeving of bonding band isolation mount U type prestress anchorage cable not have the reeve problem of device of suitable integral body; It is easy to use and reliable, traction effect good; When adopting isolation mount 5, the setting that adapts of the perforating of each through hole and isolation mount is with the straight property of assurance steel strand.
In the present embodiment, one section of through hole 11 corresponding drawing heads 2 is taper hole, and lock assembly 3 comprises two intermediate plates 31 being located between steel strand 4 and the taper hole automatically; The quantity of intermediate plate 31 also can be for more than three, and the outside of intermediate plate 31 is made as the conical surface, promptly intermediate plate 31 corresponding to the outside of cone-shaped wall be can with the conical surface of cone-shaped wall contact matching; When intermediate plate 31 placed in the taper hole, the conical surface of intermediate plate 31 can be by the direction motion of taper hole compressing to through hole 11 center lines along with in through hole 11, pushing; And then increase is to the clamping force of steel strand 4; Thereby overcome the suffered pulling force of steel strand 4, steel strand 4 can not pulled, so just steel strand 4 have been formed the self-locking clamping.
In the present embodiment, the medial surface of intermediate plate 31 also is provided with latch structure (not shown), for example on intermediate plate 31 and steel strand 4 contacted one sides, the closely-pitched detent projection is set, can increase and steel strand 4 between friction, guarantee the reliability of self-locking and locking.
In the present embodiment, drawing head 2 is provided with and is used for holding down assembly 12 with what intermediate plate 31 was pressed on corresponding taper hole, and this holds down assembly and 12 comprises limiting plate 121 and elastomeric element 122; Elastomeric element 122 is the steel spring, and an end that docks with connector 1 at drawing head 2 is provided with the installation cavity of hollow, and the bottom of installation cavity is provided with sleeve pipe 13; In sleeve pipe 13, be provided with simultaneously adjustment pad 123; Elastomeric element 122 is installed in this sleeve pipe 13, and the one of which end links to each other with adjustment pad 123, and the other end links to each other with limiting plate 121; Through selecting the adjustment pad 123 of different-thickness for use; Can regulate the thrust of elastomeric element 122 and then the thrust of regulating 121 pairs of intermediate plates 31 of limiting plate, after connector 1 and drawing head 2 docked, elastomeric element 122 made limiting plate 121 that intermediate plate 31 is pressed between steel strand 4 and the corresponding taper hole; Formation also can not deviate from steel strand 4 to the preparatory clamping of steel strand 4 when not being pulled.In other embodiments, hold down assembly and 12 can also adopt the preparatory clamping that realizes 31 pairs of steel strand 4 of intermediate plate like other pre-compacted mechanisms such as screw rod pre-compressing devices.
In the present embodiment; Be screwed connection between connector 1 and the drawing head 2, with the stop pin locking, can realize docking fast and dismantling again; Make guider dismounting in use convenient, save time; And the guider of the utility model waste and old ground tackle capable of using is processed into, and general engineering shop all can normally accomplish processing, and it is simple in structure, with low cost.
Operating principle:
When the utility model U type anchor cable integral body is reeved the guider use; Earlier connector 1 and drawing head were opened in 2 minutes; Steel strand in the anchor cable 4 cutting is passed the isolation mount 5 of right quantity after smooth; Again each steel strand 4 is penetrated on the connector 1 in the corresponding through hole 11, between the taper hole section of steel strand 4 and through hole 11, plug two intermediate plates 31 (referring to Fig. 1) then, make 31 pairs of steel strand of intermediate plate 4 form certain clamping; After this drawing head 2 is docked with connector 1; Limiting plate 121 after the butt joint keeps intermediate plate 31 is pressed in the taper hole under the effect of steel spring, even the steel strand 4 of this moment can not come off from through hole 11 by the effect of traction force yet, and steel strand 4 when receiving traction force owing to drive intermediate plate 31 with the rubbing action meeting of intermediate plate 31 and move to the little openend of taper hole; And then intermediate plate 31 is further suffered oppression produce bigger clamping force, realize the purpose of self-locking to steel strand 4.
The above only is the preferred implementation of the utility model, and the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should propose, for those skilled in the art, in the improvement and the retouching that do not break away under the utility model principle prerequisite, these improvement and retouching also should be regarded as the protection domain of the utility model.
