Embodiment
With reference to accompanying drawing 1～8, the wire rope installation tensioner comprises hoisting nut 1, lift-bolt 2, lift-bolt locking nut 4, handle 8, bearing 7.Bearing 7 hollows, top is provided with hoisting nut mounting hole 9, and bearing 7 bottoms are provided with wire rope screw rod rope slocket mounting hole 10, and the bearing bottom has nut and regulates notch 11, is used to regulate wire rope screw rod joint set screw nut 5, locking nut 4.Bearing 7 upper ends are provided with oil groove 12, reduce friction with lubricant oil.Hoisting nut 1 device is in bearing top hoisting nut mounting hole 9, and lift-bolt 2 is sleeved in the hoisting nut 1, and the screw thread of lift-bolt 2 external diameter settings matches with hoisting nut 1 internal thread, and the hoisting nut internal thread adopts buttress thread form.Hoisting nut 1 is provided with several handle mounting holes 13, and device has handle 8.Handle with sleeve 8 its length are to determine according to moment of torsion.Wire rope screw rod rope slocket 3 devices are in lift-bolt 2 internal threads, wire rope screw rod rope slocket set screw nut 5, lift-bolt locking nut 4 are housed on the wire rope screw rod rope slocket 3, spherical mount 6 is equipped with in bearing 7 bottoms, and is sleeved on the wire rope screw rod rope slocket 3.
Described hoisting nut 1 is to be formed by the metallic material machining, material need be heat-treated, improve its wear resistance and working life with the hardness that improves intensity and surface from face, its shape is to determine to process after external diameter is imitated nuclear through intensity, the hoisting nut internal thread adopts buttress thread form, buttress thread form is the transmission that motion thread is specially adapted to unidirectional power, and its length is by the screwing length decision of hoisting nut 1 with lift-bolt 2.
Described lift-bolt 2 is to form material by the metallic material machining need heat-treat, improve its wear resistance and working life with the hardness that improves intensity and surface from face, the lift-bolt external diameter adopts buttress thread form, buttress thread form is the transmission that motion thread is specially adapted to unidirectional power, its length is by imitating nuclear through screw strength and determining, its internal thread can determine according to wire rope screw rod rope slocket thread size, thereby is applicable to the wire rope of all size.Wire rope is the rope of being made by many metallic material silks.
Described bearing 7 is to be added by the metallic material machine to form material and need heat-treat, improve its wear resistance and working life with the hardness that improves intensity and surface from face, internal diameter is by cooperating with hoisting nut 1 and determining that the size of external diameter need satisfy requirement of strength and determine.
When installing, the wire rope installation tensioner earlier the screw rod rope slocket of lift-bolt 2 with wire rope 3 screwed, again bearing 7 is inserted in lift-bolt 2, again hoisting nut 1 and lift-bolt 2 are screwed to bearing 7 tops, load onto handle with sleeve 8, rotate handle with sleeve 8, hoisting nut 1 is rotated, and drives lift-bolt 2 and rises, and wire rope progressively is stretched to design load.Thin nut 4 is used to lock lift-bolt 2, and plain nut is used for the Locking Steel Wire rope.
Working principle: wire rope is installed (not having tensile state), lift-bolt 2 is screwed in the screw rod rope slocket 3 of wire rope, with locking nut 4 locking lift-bolts 2, bearing 7 is inserted in lift-bolt 2, again hoisting nut 1 is screwed in lift-bolt 2 to combining with bearing 7 tops fully, insert 2 handle with sleeves 8, wire rope in a state of nature.Carry out the prestressed stretch-draw of wire rope after this, handle with sleeve 8, driving hoisting nut 1 rotates, lift-bolt 2 moves upward, the drive wire rope makes progress, and wire rope is stretched to pretensioning gradually, does not reach the design pretensioning as promoting for the first time, need back out plain nut, carry out again promoting the second time.
