Description
Technical field
The present invention relates to the medical equipment technical field, be specifically related to a kind of fixing device of head end of steel wire rope.
Background technique
Shown in Figure 1 is suspension architecture digital radiation filming system.Shown in Figure 2 is the telescopic hoist tube of suspension architecture digital radiation filming system, telescopic hoist tube 12 has five joints and hangs tube, wherein first segment hang the tube be fixed on the main frame 11, other four the joint hang the tube by three wire rope or chain link together can realize the interlock, head 13 is installed in the bottom that the final section in the telescopic hoist tube 12 hangs tube, and can do circumference along pivotal axis and rotate; Bulb and beam light device assembly are installed on the head 13, and this assembly can be around the horizontal axis rotation.
As shown in Figure 3, five of telescopic hoist tube 12 are hung tube and adopt three wire rope to be linked together, wherein, one end of first wire rope 27 is fixed together with hanging tube 21 by wire rope fixing head 26, the other end walk around the pulley 28 that hangs on the tube 22 by wire rope fixing head (identical) with wire rope fixing head 26 structures with hang tins 23 and be fixed together; One end of second wire rope 22 is fixed together with hanging tube by the wire rope fixing head, the other end walk around the pulley 28 that hangs on the tube 23 by the wire rope fixing head with hang tube 24 and be fixed together; One end of the 3rd wire rope 23 is fixed together with hanging tube by the wire rope fixing head, the other end walk around the pulley 28 that hangs on the tube 24 by the wire rope fixing head with hang tube 25 and be fixed together.Like this when making with external force when hanging tube 25 and rising or descend, hang tube 24, hang tube 23, hang tube 22 and also can rise together or descend, thereby realize interlock between them.Wherein 26 pairs of wire rope of wire rope fixing head can use safely play a part very important.The welding type steel wire rope fixing head structure of prior art comprises copperhead 31, adjusting nut 32, adjusting screw rod 33 and wire rope 34 as shown in Figure 4.In the welded structure, the size of copperhead 31 is bigger than the diameter of wire rope 34, the head end of copperhead 31 and wire rope 34 is connected together with fixing wire rope 34 with brazing, though this structure is simple in structure, but one will guarantee that soldering point is solid and reliable when requiring welding, and two wire rope 34 will guarantee to weld the time can not annealed, in order to avoid the wire rope silk becomes fragile, be easy to break, very high to requirement of welding.Prior art is also often used compacting formula wire rope fixing head structure in addition, use fixedly head end of steel wire rope of aluminium cover, behind the steel wire penetrating aluminium cover, with external force (as hydraulic tongs) with aluminium cover compacting distortion with fixing wire rope, this structure is fixing reliable, but complicated, and with external force during with aluminium cover compacting distortion, bad as what the size of power was controlled, easily wire rope is broken.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of fixing device of head end of steel wire rope, overcomes prior art fixing device of head end of steel wire rope complicated operation when fixing wire rope, to welding technique and the demanding defective of compact technique.
The present invention solves the problems of the technologies described above the technological scheme that is adopted to be:
A kind of fixing device of head end of steel wire rope, comprise adjustable lever, the tapped hole, cone shape hole and the through hole that interpenetrate along axially setting gradually of described adjustable lever, comprise that also taper holds cover tightly, the upper end of holding cover in described taper tightly is provided with at least one opening slot, hold described taper tightly cover and be placed in the described cone shape hole, also comprise lock bolt; Fixedly during wire rope, hold described through hole of described steel wire penetrating and described taper tightly cover, then described lock bolt is screwed in the described tapped hole, also comprise the clinching piece, described clinching piece is placed between described tapped hole and the described cone shape hole, and described clinching piece is held tightly to overlap on the end face that contacts with described taper at least one groove is set.
The further optimization of described fixing device of head end of steel wire rope is: also comprise adjusting nut, on described adjustable lever outside thread is set, described adjusting nut screws described adjustable lever by described outside thread.
The further optimization of described fixing device of head end of steel wire rope is: the upper end of holding cover in described taper tightly is provided with three opening slots.
The further optimization of described fixing device of head end of steel wire rope is: described opening slot is held tightly in described taper and is put symmetrical distribution.
The further optimization of described fixing device of head end of steel wire rope is: described clinching piece is made as taper.
Beneficial effect of the present invention: the mode that fixing device of head end of steel wire rope of the present invention adopts the extruding taper to hold cover tightly, can be firmly fixing wire rope and can not make wire rope be subjected to physical property to destroy, and fixedly the operation of wire rope is very simple, has so just improved the Security and the efficiency of assembling of suspension architecture digital radiation filming system.
