Abstract
The invention provides a metal smooth-surface ground-connection tackle for paying-off. The metal smooth-surface ground-connection tackle for paying-off comprises a supporting frame, a base, a transmission shaft and paying-off wheels. The paying-off wheels are arranged on the transmission shaft through bearing pedestals with bearings. The transmission shaft is connected with the supporting frame. The supporting frame is arranged on the base. Each paying-off wheel is composed of wheel disks which are in bilateral symmetry. A first groove and a second groove are formed in the outer edge of each wheel disk and inclined towards the outer side of the corresponding paying-off wheel. An electric brush is arranged on each bearing pedestal. Each electric brush body makes sliding contact with the transmission shaft. Each electric brush is connected with the corresponding wheel disks through a wire. Grounding conductors are arranged at the two ends of the transmission shaft respectively. The metal smooth-surface ground-connection tackle for paying-off is simple in structure, low in manufacturing cost and convenient to use; the metal smooth-surface ground-connection tackle can bear large stress with small weight due to reinforcing ribs and lightening holes, and is convenient to install and transport; the paying-off wheels are made of metal materials, and the tackle for paying-off can bear large current impact and is high in safety due to the electric brushes and the grounding conductors; the wheel disks are integrally press-formed through a die, and quality of paying-off grooves formed by the first grooves is better guaranteed.
Description
Technical field
The present invention relates to the releasing pulley in the built on stilts construction of a kind of transmission line, relate in particular to a kind of metal light face grounding line paying off pulley.
Background technology
Overhead transmission line for Poling Construction releasing pulley (hereinafter to be referred as releasing pulley or coaster) be one of main facility of work transmission line Poling Construction indispensability.The constructions such as releasing pulley and unwrapping wire, stringing and annex installation have substantial connection, its effect is exactly to provide a cable tray for spreading conducting wire, the quality of passage quality not only has influence on the payingoff speed of wire, and the unfolding quality of wire, through-flow performance are also had and important impact.
The coaster that electrical network Poling Construction is used at present comprises MC nylon kiss-coating coaster and MC nylon coaster and aluminium alloy kiss-coating coaster and aluminium alloy coaster.Pulley material comprises bulk material (MC monomer cast nylon, cast aluminium alloy material) and pulley groove lining material (rubber).
The coaster of MC nylon material can only normally be worked under-30 °～+ 40 ° ambient temperatures; The intensity of cast aluminium alloy material is limited, and impact resistance is poor; Rubber and pulley body bonding not firm, is prone to the phenomenon such as occur coming unstuck, separated, has a strong impact on the quality of spreading conducting wire.In addition, adopt kiss-coating wheel or nylon wheel, under the effect of wire self tension force, wire and race level off to the face contact stabilization state of powerhouse's shape by unsettled line contact condition to weak person distortion and transform, outer and the inferior skin that easily forms wire is injured and cause impression, and wire flattens in serious even occurring, pine strand, lantern bubble.Meanwhile, traditional grounding line paying off pulley is only applicable to general electrostatic grounding, running into the situations such as live across is many, the direct contact electrification body of wire, due to coaster galvanization ability, is difficult to bear the impact of large electric current, poor stability.
Summary of the invention
The defect existing for prior art, in order to solve current grounding line paying off pulley galvanization ability, the impact that is difficult to bear large electric current, poor stability, does not meet the problem that safety requires; Solving the MC nylon coaster strength of materials poor, is to meet construction burden requirement, causes that pulley structure is complicated, volume is large, and difficult is installed; Solve MC nylon coaster material wear-resistant performance poor, easily aging, life cycle is short; Solve MC nylon coaster and aluminium alloy kiss-coating coaster material and be difficult to guarantee guide roller grooved, to spreading conducting wire mass formation adverse effect; The invention provides a kind of metal light face grounding line paying off pulley.
Concrete technical scheme is: a kind of metal light face grounding line paying off pulley, comprise bracing frame, base, power transmission shaft and actinobacillus wheel, actinobacillus wheel is arranged on power transmission shaft by the bearing pedestal with bearing, power transmission shaft is connected with bracing frame, bracing frame is arranged on base, described actinobacillus wheel is comprised of symmetrical disc, and disc outer is provided with to the first groove and second groove of the inclination of actinobacillus wheel outside; On described bearing pedestal, be provided with brush, brush body and power transmission shaft sliding contact, and brush is connected with disc by wire; Described power transmission shaft two ends are provided with earth lead.
Described disc is on conducting metal material and disc, to be provided with equally distributed lightening hole.
Described front web face is provided with and is uniformly distributed and along the reinforcement of disc radial direction.
Described web thickness is 3mm, by the moulding of mould integrated punching.
Described the second groove gradient is greater than the first groove.
The present invention is simple in structure, and cost is low, easy to use; By reinforcement and lightening hole, make when bearing larger stress, to possess less weight, be convenient to installation and transportation; Actinobacillus wheel is metal material, by brush and earth lead, makes wire barrow can bear heavy current impact, high safety; Disc is by the moulding of mould integrated punching, and the unwrapping wire groove quality being comprised of the first groove is more secure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 left view;
Fig. 3 is the first groove and the second groove structure schematic diagram.
Embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of metal light face grounding line paying off pulley, comprise bracing frame 1, base 2, power transmission shaft 3 and actinobacillus wheel 4, actinobacillus wheel 4 is arranged on power transmission shaft 3 by the bearing pedestal 5 with bearing, power transmission shaft 3 is connected with bracing frame 1, bracing frame 1 is arranged on base 2, described actinobacillus wheel 4 is comprised of symmetrical disc 6, disc 6 is for being provided with equally distributed lightening hole 12 on conducting metal material and disc 6, lightening hole 12 can reduce the weight of disc 6, be convenient to install and transportation, disc 6 outers are provided with to the first groove 7 and second groove 8 of actinobacillus wheel 4 outsides inclinations, on described bearing pedestal 5, be provided with brush 9, brush 9 bodies and power transmission shaft 3 sliding contacts, and brush 9 is connected with disc 6 by wire 10, described power transmission shaft 3 two ends are provided with earth lead 11, and the large electric current carrying in the wire setting up can pass to brush 9 by disc 6, and then brush 9 is by current delivery to power transmission shaft 3, and ultimate current imports into underground by earth lead 11, guarantee working security.
