Description

The cable laying pulley

Technical field

The utility model relates to a kind of cable-laying gear, is specifically related to a kind of cable laying pulley.

Background technology

In the general cable construction of existing special line for passenger trains, cable lays along existing cable trough, and cable trough is finished by construction before the station, and electrified H steel column organized uprightly, and cable trough is positioned at the outside of H steel column.If manually shoulder cable laying before adopting, the H steel column that must detour because power cable is heavier, needs artificial many (average 15 meters people), and particularly on grand bridge, the coefficient of safety of construction is low, and hidden danger is big; If adopt the scheme of unwrapping wire ground car mechanical traction, the outer armour of cable can be worn and torn by concrete cable groove again.

Summary of the invention

The purpose of this utility model: the problem at electrified H steel column on the existing Line for Passenger Transportation has been organized upright and concrete cable groove the cable laying coefficient of safety is low when the unit construction has been finished before the station, hidden danger is big etc. provides the cable laying pulley on a kind of H of being fixed on steel column.

The purpose of this utility model realizes in the following manner:

Described cable laying pulley, it comprises pulley bracket, nylon pulley and band steel support, described nylon pulley is fixed on the pulley bracket by the pulley set bolt, is provided with a cable slip-off preventing bolt on the pulley bracket of nylon pulley upper end; Described band steel support is a long frame shape, and a side of the upside of band steel mid-stent and pulley bracket is fixed, and the downside of band steel mid-stent and the opposite side of pulley bracket are fixed by supporting bracket; On the back side of band steel support, be provided with intermediate plate, can be fixed on the band steel support by the intermediate plate set bolt; Riveted joint has rubber blanket on the inboard of intermediate plate; Offer respectively on four jiaos of band steel cradle back and be convenient to the fixing bolt hole of intermediate plate, because the H steel column has three kinds of models, so two holes up and down on one side of intermediate plate are circular hole, and two holes up and down of another side are slotted hole.

The fixing back load-carrying of cable laying pulley is more than 1000N, and the band steel support is welded by band steel, and 4 intermediate plates of peripheral hardware are used for fixing the H steel column, the rubber blanket on the intermediate plate can, prevent the damage of the outer lacquer of H steel column; In order to prevent that cable comes off from pulley in distraction procedure, so a bolt that prevents that cable from coming off is arranged on pulley bracket.The cable laying pulley is fixed on the position of 1.5 meters of H steel columns, adopts the scheme cabling of artificial traction or mechanical traction.The utility model is applicable to that power cable lays on railway bed, the bridge in cable trough.

Compared with prior art, the utility model has the following advantages when cable laying:

1. avoided crossing electrified H steel column;

2. the laying speed of constructing is fast, has guaranteed finishing smoothly of duration, and the construction quality height can farthest reduce the wearing and tearing to the cable outer layer insulation, has reduced the incidence of cable fault;

3. significantly reduced workmen's labour and labour intensity, needed manually less, laborsaving, the required labour cost of cabling is saved half nearly, also saves half on the physical demands intensity,

4. construction safety does not have the generation of security incident;

5. saved manufacturing cost and use cost, nylon pulley is in light weight, intensity is big, durable in use.

Among Fig. 1,1-pulley bracket, 2-nylon pulley, 3-intermediate plate, 4-rubber blanket, 5-intermediate plate set bolt, 6-pulley set bolt, 7-cable slip-off preventing bolt, 8-supporting bracket, 9-band steel support, 10-circular hole, 11-slotted hole.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Among Fig. 1, Fig. 2, described cable laying pulley, it is characterized in that: it comprises pulley bracket 1, nylon pulley 2 and band steel support 9, described nylon pulley 2 is fixed on the pulley bracket 1 by pulley set bolt 6, is provided with a cable slip-off preventing bolt 7 on the pulley bracket 1 of nylon pulley 2 upper ends; Described band steel support 9 is a long frame shape, and the upside at band steel support 9 middle parts and a side of pulley bracket 1 are fixed, and the downside at band steel support 9 middle parts and the opposite side of pulley bracket 1 are fixing by supporting bracket 8; On the back side of band steel support 9, be provided with intermediate plate 3, can be fixed on the band steel support 9 by intermediate plate set bolt 5; Riveted joint has rubber blanket 4 on the inboard of intermediate plate 3.

Fig. 3 is a rearview of the present utility model, on four jiaos of band steel support 9 back sides, offer respectively and be convenient to the bolt hole that intermediate plate 3 is fixed, because the H steel column has three kinds of models, so two holes up and down on one side of intermediate plate are circular hole 10, and two holes up and down of another side are slotted hole 11.

In order to guarantee that the cable laying pulley has the support force of 1000N, pulley bracket 1, band steel support 9 select for use 50mm * 5mm band steel to make, and pulley set bolt 6 is selected φ 12 bolts for use.Intermediate plate 3 selects for use 50mm * 5mm band steel to make.When damaging, nylon pulley 2 can change, as long as pulley set bolt 6 is withdrawed from just passable.

During use, earlier cable is placed on the paying out drum, everyone holds a cable laying pulley and is separately fixed on the adjacent H steel column, cable is passed for 7 times from cable slip-off preventing bolt, and manpower draws cable to next H steel column, gives the personnel at this some place, by that analogy, after cable all launched, the bolt 7 as long as the anti-cable of release comes off just can drop on cable in the cable trough.
