Specific embodiments
As shown in Figures 1 to 7, a kind of Large scale cable crane track cable group anchor device, is moved and is drawn fixed structure to be formed by supporting structure, weight cable group anchor beam structure, weight cable anchor beam adjustment structure and anchor beam.Wherein:
As shown in Figures 1 to 6, supporting structure, for supporting and fixedly weight cable group anchor beam structure, weight cable anchor beam are adjusted structure and anchor beam and moved and draw fixed structure.By perpendicular, fix beam 12 and horizontal solid beam 13 is formed.Supporting structure is positioned at the front portion of cement bank base 15.Side by side and be the sides of affixed horizontal Gu Liang between two of the spacing distance setting perpendicular upper ends that fix beam, the opposite side of horizontal Gu Liang is also fixed in other two perpendicular fixing between the upper end of beam, and each perpendicular lower end that fixes beam is installed in cement bank base.Because weight cable group anchor beam structure, weight cable anchor beam adjustment structure and anchor beam move, draw fixed structure to be 2 identical structures, lay respectively at the both ends of horizontal Gu Liang, therefore only the said structure of a side is described, opposite side is corresponding to be arranged, therefore be not repeated.
As shown in Figures 1 to 5, weight cable group anchor beam structure 14, for fixing the termination of each weight cable, is consisted of anchor beam 4, semi-circular saddle 6.Two weight cable group anchor beam structures lay respectively at the both ends of horizontal Gu Liang.The front end face middle part of anchor beam is provided with front stiffening girder 3, and the rear end face middle part of anchor beam is provided with rear stiffening girder 9.Forward and backward stiffening girder is for strengthening the bulk strength of anchor beam.The middle part of forward and backward stiffening girder and anchor beam is provided with and connects through wires hole 16.The both sides of stiffening girder after two semi-circular saddles lay respectively on the anchor beam of one end.The termination of each weight cable 2 fixing winding forming that unrolls is set on anchor beam and horizontal Gu Liang and semi-circular saddle, that is: unrolled in the two ends of each weight cable and use locked this termination of cable snap close 1 in the place of unrolling, make the two ends of weight cable form winding, winding is set on anchor beam and horizontal Gu Liang and semi-circular saddle.
As shown in Figure 6, weight cable anchor beam is adjusted structure, for carrying out length adjustment to being set in structural each weight cable of weight cable group anchor beam.By enter to carve groove 5 and the steel that are positioned at semi-circular saddle outside, carve plate 19 and formed.One end that steel is carved plate is tip end, and the height of plate carved by steel and the aspect ratio of semi-circular saddle is 0.7: 1, and the length that steel is carved plate is greater than the length of semi-circular saddle.When steel is carved plate and is inserted between semi-circular saddle outside and corresponding anchor beam face.It is several that described steel is carved plate.When needing the length of each weight cable of inching, several steel are carved to plate (stack, need each to be inserted into respectively) tip end aim at into carving groove and be inserted into respectively the gap between horizontal Gu Liang and semi-circular saddle, both are widened distance, after making to be set in each weight cable winding on anchor beam and horizontal Gu Liang and semi-circular saddle, move, thereby complete the length of adjusting each weight cable.
As shown in Fig. 5 and Fig. 7, anchor beam moves and draws fixed structure, for moving, draws fixing rack structure and weight cable group anchor beam structure.By front anchor slab 11, rear anchor slab 17, steel strand 8, put spool 7 and steel tapered anchor bolt 10 is formed.Forward and backward anchor slab is provided with the cable-through hole passing for steel strand termination, and a steel strand termination is through a cable-through hole.Front anchor slab is positioned at the front end of the perforation through wires hole on front stiffening girder, and the inner peripheral portion card of front anchor slab withstands on the front stiffening girder in cable-through hole outside.Put the cement bank base that spool is positioned at the perforation through wires hole position on corresponding rear stiffening girder.The spool outside of putting of the cement bank base of rear side is provided with rear anchor slab, and the inner peripheral portion card of rear anchor slab withstands on the cement bank base of putting spool outside.One termination of several steel strand through putting spool, connect through wires hole and be connected with steel tapered anchor bolt with after each cable-through hole on front anchor slab, another termination of several steel strand is connected the rear steel crab-bolt 18 of using of adjustment through each cable-through hole on rear anchor slab and fixes with hydraulic adjustment device.
Described hydraulic adjustment device is comprised of body 25 and two hydraulic cylinders 26.Body is one certain thickness and withstand voltage pressure-bearing steel plate, and two hydraulic cylinders are fixed on body two ends, and body middle part is provided with the piston rod 20 of putting line hole 22, two hydraulic cylinders and ejects to a side.Oil-in 24 on two hydraulic cylinders communicates with the force feed outlet of oil pump by pump inlet pipe, and the oil return opening 27 of two hydraulic cylinders is answered back and communicated with the force feed of oil pump by oil pump oil return pipe.
The termination of described steel strand is threaded portion 81.Described forward and backward reinforcement depth of beam is identical with anchor depth of beam.It is several that described steel is carved plate.Described steel strand are several.Described perpendicularly fix beam and horizontal Gu Liang is i iron.
During construction, one termination of several steel strand is through putting spool, connecting after each cable-through hole on through wires hole and front anchor slab, with steel tapered anchor bolt, connect respectively, another termination of several steel strand is connected adjustment through each cable-through hole on rear anchor slab with hydraulic adjustment device rear fixing by steel crab-bolt 18.Above-mentioned anchor beam moves to draw fixed structure to form fixing rack structure, weight cable group anchor beam structure and weight cable anchor beam are adjusted to moving of structure and draws fixing.The termination of each weight cable fixing winding forming that unrolls is set on anchor beam and horizontal Gu Liang and semi-circular saddle, forms fixing to each weight cable.
While if desired adjusting the length of each weight cable, available hydraulic adjusting device carries out.Hydraulic adjustment device can be several, and the line hole of putting of each hydraulic adjustment device is passed behind the termination of steel strand, puts successively pad card 23 and screws on and adjust holding nut 21.The top of two-piston bar holds on rear anchor slab, then opens hydraulic oil pump, and the piston rod of two hydraulic cylinders ejects, drive body moves up, each moving range length 10～18cm, and simultaneously drive anchor beam to move backward, completes by the length adjustment of each weight cable.After each weight cable is adjusted to the right place, tighten steel crab-bolt and fix it on rear anchor slab.
Obviously, after first making the piston rod of two hydraulic cylinders eject, manually as required steel crab-bolt is loosened after certain length, make again hydraulic piston rod fall after rise, carry out also can the lengthen length of each weight cable of reverse operating, complete after length adjustment, tighten steel crab-bolt and fix it on rear anchor slab.Therefore be not repeated.
If desired during the length of each weight cable of inching, the tip end that several steel are carved to plate is aimed at into carving groove and is inserted into respectively the gap between horizontal Gu Liang and semi-circular saddle, both are widened distance, make to be set on anchor beam and horizontal Gu Liang and semi-circular saddle and move after winding, thereby complete the length of each weight cable of inching (scope length 5～8cm).
In a word, the utility model not only can provide effectively fixing to the two ends of weight cable, and can effectively to the length of each weight cable, adjust at any time, have simple in structure, flexible operation, job safety is convenient, result of use is good, speed of application is fast, and efficiency height and the measured advantage of matter, can promote the use of.
