Abstract
The invention discloses an energy-saving general lead laying pulley. The pulley comprises a support (1), a horizontal support (2) is connected with the lower end of the support (1), three rollers (4) which are arranged in an arc are hinged to the horizontal support (2), and a lead (5) is overlapped with the three rollers (4). According to the energy-saving general lead laying pulley, the horizontal support is connected with the lower end of the support, the rollers arranged in the arc are hinged to the horizontal support, and the lead is overlapped with the three rollers, so that the three small rollers arranged in the arc can form a curved surface of the lead laying pulley; thus, the lead laying pulley can completely satisfy the requirement for the groove bottom diameter described in the third clause of the DL/T685-1999 ''basic requirement, examination prescription and test method for line laying pulleys''. The energy-saving general lead laying pulley can be compatible with leads in different sectional areas, so that a user is not required to own different types of line laying pulleys; and purchasing and management cost is reduced.
Description
Technical field
The present invention relates to the general wire releasing pulley of a kind of prompt energy, belong to superhigh pressure, UHV Overhead Transmission Line wire stringing constructing device.
Background technology
The wire releasing pulley is widely used in the overhead power transmission engineering construction.Be accompanied by development and the extension of power grid construction, the construction of trans-regional grid network and large hydropower station, near coal-mine thermal power station, superhigh pressure, extra-high voltage alternating current-direct current transmission line construction are like a raging fire.it is exactly the continuous increase of sectional area of wire that the electric weight of vast capacity carries the thing followed to require, the structure of existing wire releasing pulley as shown in Figure 3, according to rower DL/T685-1999 " pulley block basic demand, inspection provision and method of testing " the 3rd regulation to pulley block bottom land wheel footpath, increase due to diameter of wire, the diameter of the actinobacillus wheel of releasing pulley just requires to continue to increase thereupon, cause the weight of releasing pulley, volume will be increasing, the MC nylon that uses and steel are more and more, the kind of releasing pulley also becomes increasingly complex, caused the huge wasting of resources, and cause storing and the management cost increase.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lightweight, be easy to load and unload, carry, transport, can reduce the releasing pulley specification, reduce the use of purchasing with management cost expenditure, minimizing MC nylon and steel, saving resource, reduce and consume, meet the general wire releasing pulley of victory energy of the national strategy of energy-conserving and environment-protective, can overcome the deficiencies in the prior art.
Technical scheme of the present invention is: the general wire releasing pulley of prompt energy, and it comprises support, in the support lower end, is connected with horizontal stand, on horizontal stand, is hinged with three and is the pulleys that camber line is arranged, wire is overlapped on three pulleys.
At horizontal stand, be provided with installing hole, pulley is hinged on installing hole, and the quantity of installing hole is more than 1, and the installing hole more than 1 is linear array on horizontal stand.
The camber line diameter that is three pulleys of camber line arrangement meets the 3rd requirement to the pulley block groover rot diameter of DL/T685-1999 " pulley block basic demand, inspection provision and method of testing ".
The camber line diameter that is three pulleys of camber line arrangement is not less than 900mm.
in prior art relatively, 1, the present invention is by being connected with horizontal stand in the support lower end, on horizontal stand, be hinged with three and be the pulley that camber line is arranged, wire is overlapped on three pulleys, so just can be built by three little pulley bodies that are the circular arc layout circular arc camber of pulley block, make it meet DL/T685-1999 " pulley block basic demand fully, inspection provision and method of testing " the 3rd requirement to the pulley block groover rot diameter, and the wire of the backward compatible different cross-sectional that can make progress, reduce the user and releasing pulley is had to the requirement of kind, reduce to purchase with management cost and pay.2, the coaster groover rot diameter is large, reduces largely the flexural deformation of Bending Damage and the lead splicing sleeve protective sleeve of lead splicing sleeve, reduces construction cost.3, reduce the releasing pulley volume, alleviate releasing pulley weight, be easy to loading and unloading, carrying, transportation, reduce use cost.4, reduce the use of MC nylon and steel, saving resource, reduce and consume, and meets the national strategy of energy-conserving and environment-protective.The quantity that the installing hole of pulley is installed is more than 1, and the installing hole more than 1 is linear array on horizontal stand, like this for different wires can be suitable the circular arc camber that builds of adjusting three pulleys, can cover the unfolding of all sectional area wires.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of horizontal stand (2);
Fig. 3 is the structural representation of the wire releasing pulley that provides of rower DL/T685-1999 " pulley block basic demand, inspection provision and method of testing ".
