Description
Technical field
The utility model belongs to overhead transmission line tension stringing construction equipment field, is specifically related to a kind of " one leads three " tension stringing asymmetric traction plate.
Background technology
Tension stringing is meant construction equipment and facility spreading conducting wires such as using hauling machine, tensioner, releasing pulley, towing plate, lead is let slip in exhibition had certain force of strain in the journey, be put into a kind of payingoff construction method on each basic shaft tower in the unwrapping wire section thereby liftoff, the across obstacle of soaring is built on stilts state exhibition.At present, tension stringing has become the main form of construction work that domestic and international general overhead transmission line conductor sets up, compares artificial unwrapping wire, its have the lead wearing and tearing little, save manpower, improve clear superiorities such as work efficiency.
The connection situation of various device, facility, line, rope as shown in Figure 1 in the tension stringing: guiding rope 1 front end links to each other with hauling machine, tail end links to each other with main pull rope 2; The tail end of main pull rope 2 uses steel wire rope to link to each other with towing plate 4 with rotary connector 3; Towing plate 4 afterbodys link to each other with quilt exhibition lead 6 with rotary connector 5 by lead; Lead 6 tail ends are then reeled and are connected on the tensioner.Tension stringing divides following step to carry out: at first use artificial or alternate manner spreading guiding rope (being generally the composite fibre rope), utilize guiding rope traction exhibition to put main pull rope (being generally steel wire rope) again, at last with main pull rope traction spreading conducting wire.The length of general unwrapping wire section has how basic transmission tower therebetween in 8 kilometers, need hang releasing pulley on every basic shaft tower during unwrapping wire, so that provide support and passage is put in exhibition for lead.Therefore, towing plate and releasing pulley are the indispensable facility of tension stringing, have important function to finishing wire erection, guardwire, raising payingoff construction efficient.
Current widely used towing plate and releasing pulley structurally all are symmetric forms, as: one leads two towing plates, leads four towing plates, and leads six towing plates and and lead eight towing plates, and releasing pulley correspondingly is respectively three wheel line tackles, five wheel line tackles, seven-wheel line tackle and nine wheel line tackles.The exhibition that above-mentioned towing plate and the corresponding supporting use of releasing pulley can be satisfied two bundle conductors, conductors on quad bundled, six-multiple conductor and eight bundle conductors is respectively put needs and (single conductor is only used the single-wheel releasing pulley, need not towing plate, main pull rope directly is connected with lead).Fig. 2 leads two symmetric form towing plates for tradition one, mainly is made up of big guiding arm-tie 11, traction plate body 12, little guiding arm-tie 13 and anti-twister 14.Traction plate body 12 is a symmetrical structure, and the big guiding arm-tie 11 that is connected with main pull rope is positioned at the front end center position of traction plate body 12; Anti-twister 14 is positioned at the tail end center position of traction plate body 12; Two little guiding arm-ties 13 that link to each other with lead are positioned at the tail end of traction plate body 12, relatively towing plate center symmetric arrangement.In the unfolding conductor process, when there are the small number of bad different time in the degree of lengthening of exhibition of two leads, overhang etc., anti-twister 14 can prevent the upset of towing plate.Figure 3 shows that three wheel line tackles that match with Fig. 2, it mainly is made up of link plate 23, support 24, bolster 26, a wire rope pulley 25 and two lead pulleys 27 etc.Wherein wire rope pulley is positioned at the coaster center, in order to restrict and main pull rope by guiding; Two relative wire rope pulley symmetric arrangement of lead pulley are in order to pass through lead; Using the suppending hole 22 of connector 21 such as steel wire rope by link plate that releasing pulley is hanging on the transmission tower or directly is suspended on the insulator string.
Along with improving constantly of China's overhead transmission line electric pressure, the sectional dimension of transmission pressure correspondingly and weight are also in continuous increase, and the load that unwrapping wire equipment such as hauling machine, tensioner are born also increases thereupon.When multiple fission conductor is put in exhibition, require its each root lead to open up synchronously and put, to reduce the influence that creep causes lead.But for heavy in section, multiple fission conductor, because its weight is bigger, existing both at home and abroad separate unit pulling equipment can't satisfy the needs that all leads are put in disposable exhibition simultaneously.As six division large-section leads, an existing hauling machine can't once all be opened up its six conductors and put, restricted by existing towing plate and releasing pulley, can only open up and put by adopting six groups " one leads one ", three groups " one leads two " or " one the leads two "+mode of " leads four ", to satisfy construction requirement.Cause thus that simultaneously used device is many, construction is complicated, efficient is low, synchronism is difficult for assurance.Therefore, for make full use of existing open the equipment that leads, to greatest extent performance existing open lead capacity of equipment, minimizing equipment drops into, improves efficiency of construction, adopting two groups of " one leads three " modes to open up to put six division large-section leads is a kind of more economic, construction plan efficiently.If will have now one lead four towing plates be used for " one leads three " construction, because the lead radical difference that the towing plate both sides connect, it will produce moment of torsion to towing plate, and anti-twister can't overcome so big moment of torsion, thereby cause the towing plate upset and construction is put in the exhibition that can't realize.
The utility model content
For overcoming above-mentioned defective, the purpose of this utility model is to provide a kind of existing tensioner, hauling machine of making full use of, for simplifying six division large-section lead unfolding process, improve payingoff construction efficient, ensureing the payingoff construction quality, provide a kind of and satisfy the asymmetric traction plate that " one leads three " unfolding conductor construction plan requires.
For this reason, the utility model is taked following technical scheme: a kind of " one leads three " tension stringing asymmetric traction plate, comprise traction plate body, anti-twister, be used to connect the big guiding arm-tie and the little guiding arm-tie that is used to be connected lead of main pull rope, the front end of described traction plate body is provided with big guiding arm-tie, the rear end of traction plate body is provided with little guiding arm-tie and anti-twister, described towing plate adopts unsymmetric structure, is provided with a little guiding arm-tie in case the axis of twister is a separator bar in a side of traction plate body, opposite side in traction plate body is provided with two little guiding arm-ties.
Wherein, the axis of described anti-twister coincides with the axis of big guiding arm-tie.
Wherein, the rear end of described traction plate body is provided with a contiguous block, and anti-twister is connected with this contiguous block by bearing pin, and the axis of described anti-twister and the axis of contiguous block coincide.
Wherein, equal the axis of two little guiding arm-ties of traction plate body opposite side to the vertical range sum of anti-twister axis in the axis of a little guiding arm-tie of traction plate body one side to the vertical range of anti-twister axis.
Wherein, be provided with balancing weight being provided with lightening hole on the side of the traction plate body that is provided with a little guiding arm-tie or being provided with on the side of traction plate body of two little guiding arm-ties.
