Abstract

The utility model discloses a heavy -calibre PVC U tubular product draw gear, including the tight device in screw top, movable claw device, couple, the tight device in screw top comprises 2 nuts and a screw rod, and the movable claw device comprises supporting shoe, removable pin and 4 rest shoes, the tight device in adoption screw top pushes up tight, reuse leading couple with the movable claw with plastics pipe inner wall through the supporting shoe and hangs the wire rope who goes up the tractor, the one -time -reach -place, and quick convenience reduces the waste of tubular product and spatial position's the problem of drawing.

Description

A kind of heavy caliber PVC-U tube traction devices

Technical field

This utility model is related to plastic conduit manufacturing, and in particular to a kind of heavy caliber PVC-U tube traction devices.

Background technology

In the prior art tubing using traction method be with pipe trombone slide, exactly with a PVC-U pipe come trombone slide, but As heavy caliber PVC-U pipelines just have 30 meters from head to traction machine, if with pipe come the method for trombone slide it is comparatively laborious and Pipe pulls out back location between rear car and cannot accommodate this 30 meters long traction pipelines, can push up workshop body of wall.

Utility model content

For above-mentioned deficiency in work, this utility model is the ejecting device using umbrella principle, ejects four by screw mandrel Pawl supports and is capable of achieving quickly to hold out against PVC-U pipe material inner walls.Clamping and positioning is solid and reliable, will not fall off, then by device front end Traction apparatuss sync pulling on hook and traction machine.

The technical scheme adopted for achieving the above object by this utility model is：A kind of heavy caliber PVC-U of this utility model Tube traction device, including screw holding device, movable jaw arrangement, hook, screw holding device is by 2 nuts and a screw rod Constitute, movable jaw arrangement is made up of support block, removable pin and 4 rest shoes；Using screw holding device, by support block by activity Pawl and plastic pipe inwall hold out against, again with the preposition steel wire rope for hanging up traction machine, one-time-reach-place, quick and convenient reduction are led The waste of skirt material and the problem of locus.

In order to ensure gap optimal between critical piece, freely, using linear cutter, pin-and-hole is using hinge for rest shoe activity Hole, pin adopt grinding, to ensure quality of fit.

In order that rest shoe is durable in use, its material is made using 40Cr steel, and its intensity and wearability are than common No. 45 Steel wants high by more than 20%.

The utility model has the advantage of：Promoted using screw rod, be capable of achieving Quick fastening, quick, rest shoe Jing easy to loading and unloading Durable long, centering is quick, work efficiency is greatly improved, and reduces the waste in space, and economic benefit, production efficiency are substantially carried at double Rise.

Description of the drawings：Structural representations of the Fig. 1 for this utility model embodiment 1；

Specific embodiment：Below by embodiment, with reference to accompanying drawing, the utility model is described in further detail.

As shown in figure 1, this utility model kind heavy caliber PVC-U tube traction devices, including screw holding device 1, activity Jaw arrangement 2, hook 3, screw holding device 1 is made up of 2 nuts 11 and a screw rod 12, movable jaw arrangement 2 by support block 21, Removable pin 22 and 4 rest shoes 23 are constituted.

Decline movable jaw arrangement 2 by rotation of the nut 11 on 12 screw rods, now rest shoe 23 is inwardly retracted to than modeling Material pipe internal diameter is little, rest shoe 23 is filled in inside plastic pipe, whole traction apparatuss is completely disposed inside tubing.

As pipe internal diameter is larger, people can be in tubing built-in function, so being lifted up supporting by rotating nut 11 Block 21 withstands plastic pipe inwall, due to removable pin 22 be head thus during 23 outside swell of rest shoe can free inclination be close to Pipe material inner wall, and 23 surface of rest shoe has annular knurl increase friction, thus when rest shoe 23 holds out against plastic pipe inwall just can be with It is firm to clamp tubing.

It is to play fastening effect that nut 11 has 2, it is to avoid be reversed the hidden danger for causing jaw to loosen, this device fastener tube The steel wire rope on traction machine 3 is hung up by hook after material inwall, so that it may realize without 30 meters of long traction tubes doing asking of drawing Topic.

This utility model includes being not limited to above-mentioned embodiment, using identical with this utility model above-described embodiment or near As structure, and obtain other structures design, within protection domain of the present utility model.

Claims
