Abstract

The utility model discloses a detachable double-pulley device. The detachable double-pulley device comprises two pulleys and pulley frames, each pulley comprises a sliding wheel, and the sliding wheels are arranged in the pulley frames via sliding wheel shafts. Each pulley frame comprises two supporting rods, the upper ends of the supporting rods are connected via a connecting plate, and the lower ends are connected via a connecting rod. The two pulleys are connected via a transverse rod and inclined rods. The detachable double-pulley device of the utility model can protect a steel core of a conducting wire better, is wide in application range, can be assembled by common materials, and is economic and practical.

Description

A kind of detachable sister block device

Technical field

The utility model relates to a kind of coaster.

Background technology

In current transmission line restringing operation, use more corner block because landform restriction is necessary, and traditional gin block is because the restriction in wheel footpath causes the envelope angle of wire too small, easily damage steel core, especially require envelope angle to be greater than 120 ° for carbon fiber capacity-improving conducting wires, not so can produce huge damage to plug.Workmen changes in capacity-improving conducting wires engineering construction at 110kV woods Feng line, and because the wire using is carbon fiber composite core wire, its excellent core is easily brittle failure in the situation that being subject to energetically, therefore requires working corner block envelope angle must not be less than 120 °.But due to landform restriction, cannot guarantee that through tower corner block coaster envelope angle is greater than 120 ° from the wire of tensioner outlet, existing large coaster of taking turns footpath 500cm only can guarantee 90 ° of envelope angles, also be difficult to meet the requirement at envelope angle, and the sister block of manufacturer production is approved product, very heavy, be unfavorable for building site transportation, and in the time that the sectional area of wire of changing changes, the groove width of coaster and wheel footpath are all had to new requirement, cannot change.

Summary of the invention

Given this, the utility model object is to provide a kind of tackle arrangement of not easy damaged steel core, the convenient transportation of this device, and applicability is wide.

For solving above technical problem, the technical scheme that the utility model provides is, a kind of detachable sister block device is provided, comprise two coasters and apparatus for suspension, described coaster comprises a pulley, and pulley is arranged in pulley yoke by pulley spindle, and this pulley yoke has two support bars, the upper end of support bar connects by connecting plate, and the lower end of support bar connects by connecting rod; Two coasters are connected with brace by cross bar.

Further, described support bar lower end is also welded with base plate.

Preferably, the two ends of described cross bar connect respectively the upper end of two support bars.

Preferably, described brace is two, becomes fork-shaped setting, and one end of brace connects the upper end of a support bar, and the other end of brace connects the lower end of another support bar.

Preferably, the infall of described brace is bolted.

Compared with prior art, a technical scheme tool in technique scheme has the following advantages:

1, the utility model steel core of guardwire preferably, applied widely.

2, the utility model is convenient detachable, convenient transportation.

3, the flat board of the utility model bottom can make this device steadily place.

4, the utility model can use common materials assembling, economical and practical.

Embodiment

Describe below in conjunction with accompanying drawing and a specific embodiment.

Referring to Fig. 1 to Fig. 4.The described detachable sister block of the present embodiment device, comprises two coaster and the apparatuss for suspension of installing side by side.Described coaster comprises a pulley 10, and pulley 10 is arranged in pulley yoke by pulley spindle 11.Described pulley yoke has two support bars 12, and its lower end is welded with base plate 14.The upper end of support bar 12 connects by connecting plate 13, and the lower end of support bar 12 connects by connecting rod 15.Connecting plate 13 is set square, on each angle, is provided with connecting hole, and wherein two holes are support bar connecting hole, and another hole is suppending hole, can be used for articulating hook or rope.Two coasters are connected with brace 30 by cross bar 20, i.e. cross bar 20 and brace 30 made block framves.

The two ends of cross bar 20 connect respectively the upper end of two support bars.Brace 30 is two, becomes fork-shaped setting, and one end of brace 30 connects the upper end of a support bar, and the other end of brace 30 connects the lower end of another support bar.Cross bar 20, brace 30 and support bar 12 junctions, upper end are connected by stay bolt 40, and brace 30 and support bar 12 lower ends are bolted, and the infall of two braces 30 connects by bolt 31.

Cross bar 20 and base plate 14 can be selected angle steel, and brace 30 can be selected band steel, draw materials extensively.

Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection range of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
