Abstract
The invention discloses a cable wellhead pulley. The cable wellhead pulley comprises more than one group of pulleys, wherein each pulley comprises a pulley wheel which is arranged between two connecting plates, and two supporting rods; adjacent pulley blocks are rotatablely connected with each other; and one end of each supporting rod is rotatablely connected with a connecting plate of each pulley block, and the other end of each supporting rod is a clamping end. The cable wellhead pulley is low in cost, convenient to use, and high in working efficiency; and more importantly, the cable wellhead pulley is safe and reliable.
Description
Technical field
The present invention relates to the cable laying instrument.
Background technology
Cable laying is when the turnover well head, and the mode that the well head coaster is placed in general employing is protected cable and conveniently laid.But there is certain potential safety hazard in the cable wellhead coaster that uses now in cable laying the time.Particularly when cable access, cable can discharge the swing of cable torsion and thereupon swing along with cable hank.The well head coaster is owing to can't fix, excessive or the cable hank of cable hank width is subjected to the influence of topography can not put timing, the well head coaster can be turned on one's side, in case rollover will affect the cable laying progress, can and can damage workmen and pedestrian the cable injury if deal with improperly.
Summary of the invention
Given this, the object of the invention is to provide a kind of well head coaster that can fix.
For solving above technical problem, technical scheme provided by the invention is, a kind of cable wellhead coaster is provided, comprise one group of above coaster, the structure of described coaster is, is pulley between two connecting plates, be rotationally connected between the adjacent pulleys group, also comprise two support bars, the connecting plate of this support bar one end and assembly pulley is rotationally connected, and the other end is bare terminal end.
The bare terminal end of described support bar is two mutual parallel holding pieces, is provided with screw on the holding piece, and screw rod is screwed on the screw.
Compared with prior art, well head coaster of the present invention is with low cost, easy to use, has improved operating efficiency; The more important thing is safe and reliable.
Description of drawings
Fig. 1 is the front view of cable wellhead coaster of the present invention.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the stereogram of Fig. 1.
Embodiment
Describe below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1 to Fig. 3.The cable wellhead coaster that present embodiment is described comprises one group of coaster and two support bars 3.Connecting plate 1 is triangular form, and each angle is fillet, and the position of centre of gravity of connecting plate 1 is provided with a centre bore, is respectively arranged with a connecting hole near two fillets at the place, long limit of connecting plate 1.Coaster comprises two connecting plates 1 and a pulley 2, and pulley 2 is between two connecting plates 1.The axle at pulley 2 two ends and the centre bore on the connecting plate are rotatably assorted.When using many group coasters, be rotationally connected between the adjacent pulleys group, that is to say, by the connecting hole on the connecting plate of screw rod connection adjacent pulleys group.The connecting plate 1 of support bar 3 one ends and assembly pulley is rotationally connected, and the other end is bare terminal end.The bare terminal end of support bar 3 is two mutual parallel holding pieces, is provided with screw 4 on the holding piece, and screw rod 5 is screwed on the screw 4.During use, holding piece blocks the well head circle, and rotary screw 5 is fastening to it.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with the claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
