Abstract
The present invention is a kind of hollow core cable fixture block and application method that can be used for wind-power generating unit tower.The component is formed by nylon compacting, the uniform several bolts hole in surface, and using the support of rice word at bolt hole, remaining is supported for " X " type.Hollow design, fixture block quality is reduced while overall construction intensity stability is ensured；To adapt to different size cable size in pylon, different grooves are designed；Using 4 pieces of fixture block clampings arranged side by side, 2 layers of parallel cable groove are formed, it is ensured that shorten fixture block length in the case that clamping cable sum is constant as far as possible.Above-mentioned hollow core cable fixture block, its combined method:Fixture block is bolted on cable bearer, fixture block is locked with locking nut, after required fixed cable is respectively placed in fixture block groove, fixture block, fixture, packing ring, nut are placed on fixture block from the bottom to top, finally by top layer nut check, double-deck cable clamping is formed, cable is completed and fixes.
Description
Technical field
The hollow fixture block and application method fixed the present invention relates to a kind of wind power generating set copper cable.
Background technology
Wind-power generating unit tower cable clamping block unit is mainly used in pylon inner cable being fixed on to prevent cable from sliding on cable trough, while completely cutting off cable mediate contact and then the electric current produced, prevents further to trigger the potential dangers such as fire.
The pylon cable fixture block of existing Wind turbines is mainly made up of nylon, is solid construction, several notches are dispersed with each fixture block.Generally several pieces of fixture blocks are shared in use, notch is harmonious as closing gap between two fixture blocks, and cable is clamped connection by the space between cable fixture block by bolt.
The pylon inner cable fixture block of a current wind power generating set is about dispersed with 34 ~ 45 according to tower height difference, often place's clamping fixture block through bolt connection into a monoblock cable fixture block, every piece of fixture block net weight is about 4.2kg, and to ensure its big frictional behaviour and light characteristic, material elects nylon66 fiber as.With the further increase of wind power generating set single-machine capacity and rotor diameter, cable size is increasing, and in order to effectively fasten increasingly heavier cable, the size of cable fixture block is also gradually increasing, therefore the cost of raw material of nylon66 fiber great number is urgent problem to be solved.Meanwhile, there is certain interval between cable fixture block and cat ladder, the farthest operating distance of installation personnel is up to 1 meter, and this is that installation personnel causes very big difficulty in operation, complete whole tower cable fixture block installation and take time and effort as problem urgently to be resolved hurrily.With the increase of blower fan MW numbers and cost of labor, solid cable fixture block ultralong overweight turns into design, the economy problems that can not avoid.
The content of the invention
To solve existing pylon cable fixture block economic and installation limitation problem caused by material, weight, length etc., the invention provides a kind of new structure available for wind-power generating unit tower cable fixture block.
The present invention solves the scheme that is used of its technical problem：The cable fixture block is formed by nylon compacting, internal uniform several bolts hole, supported outside hole using " X " type and " rice " font, supported at bolt hole using rice word, remaining is supported for " X " type, all skies in addition to hole position and supporting construction, bolted combined method is used by polylith fixture block, fastens cable.
Above-mentioned hollow core cable fixture block, its combined method is：Fixture block is bolted on cable bearer, fixture block is locked with locking nut again, is placed in fixture block, fixture, packing ring, nut on fixture block from the bottom to top after required fixed cable is respectively placed in fixture block groove, finally by nut check, double-deck cable clamping is formed, cable is completed and fixes.
Above-mentioned hollow core cable fixture block, its different flute profile are suitable for clamping varying number, the cable of different line footpaths.
The beneficial effects of the present invention are can be greatly lowered cable fixture block materials, and then outstanding contribution is made for pylon economy；Because the fixation of cable fixture block and cable is all to be completed by staff's climbing on the cat ladder by cable trough, being greatly lowered for cable fixture block weight and length is of great importance for the reduction of staff's working strength.The design of cable fixture block and installation of wind power generating set and superelevation pylon simultaneously for large-diameter cable provide solution, and the economy of wind power generating set cable fixation is improved to a certain extent.The cable fixture block net weight is 1.8kg, weight reduces 1/2, and cable fixture block total length is shortened with multilayer installation way, solves the installation of cable fixture block and manpower consumes problem excessively, being greatly reduced for labor hour, largely improves the economy of wind power generating set.The design not only solves the big economical problem of installed capacity cable fixture block, while providing more excellent design for the fixation of the larger diameter such as aluminium cable wind power generating set and the cable of superelevation pylon.
Brief description of the drawings
Fig. 1 is three dimensional structure diagram of the present invention.
Fig. 2 is two-dimensional structure schematic diagram of the present invention.
Fig. 3 is installation diagram of the present invention.
In figure：1st, X-type is supported；2nd, rice word is supported；3rd, bolt hole；4th, chain connecting bolt；5th, nut；6th, packing ring；7th, 8,9,10,11 fixture block；12nd, locking nut；13rd, cable bearer；14th, 15,16, cable.
Embodiment
Referring to Fig. 1, the uniform several concave grooves in the cable fixture block outer surface top, several pieces of similar fixture blocks form closed pockets to folder when using, and cable is placed in groove.Therefore number of recesses, by treating that clamping number of cables is determined, groove size is determined by cable size.It is in net distribution structure inside fixture block, referring specifically to Fig. 2.
Inside Fig. 2 fixture block, 1 is X-type support, and 2 be the support of rice word, and 3 be spiro keyhole position, and entire infrastructure is vacant in addition, is consequently formed hollow entity.Several pieces of identical fixture blocks are connected on cable trough to folder with what bolt was loosened when using, cable completes the fixation of cable by fastening bolt behind space between cable fixture block.
Referring to Fig. 3, part 7,8,9,10 is respectively variform fixture block, and part 4,5,6 is respectively chain connecting bolt, nut, packing ring, and part 13 is cable bearer, and part 12 is locking nut.In assembling process, the bolt 4 of fixture block 10 is fixed on cable bearer 13, then locked fixture block 10 with locking nut 12；Secondly required fixed cable is respectively placed in the groove of fixture block 10, fixture block 8 and 9 is then placed in 10 tops by bolt 4 and locked with locking nut 12；Finally cable, fixture block 7, fixture 11, packing ring 5, nut 6 are placed on fixture block 8 from the bottom to top, finally by nut check, double-deck cable clamping is formed, completes cable and fix.
According to Fig. 3 two layers of clamping slot arranged side by side of visible 4 pieces of cable fixture blocks formation, the groove has 3 kinds of shapes.Groove 14 can the medium model cable of clamping 3, cable triangle is closely adjacent；Groove 15 can be with 3 cables of rounded projections arranged mode clamping, but this cable size is less than former；Groove 16 can side by side clamping two compared with thick cable.The installation way takes into full account different model cable specification in pylon, can complete clamping and the fixation of various cables.
