Abstract

The utility model relates to a device which uses a roller to orderly wind and rewind a dragrope wound round the roller. The device has the technical proposal that the roller is fixedly arranged on a rotating shaft, and the dragrope is wound round the roller; the outside of two ends of the rotating shaft is sleeved with a radial collar connected with the rotating shaft, a swinging rod is connected on the radial collar, and a compression roller is arranged between end parts of the swinging rod; the radial collar or more than two anchor ears adopts a combination forming; the swinging rod is arranged on one anchor ear; two end of the roller is provided with a raised retaining edge. The radial collar can be disassembled conveniently and the dragrope can be wound and rewound orderly to avoid the disorder running of equipment.

Description

The drag rope draw off gear

Technical field

The utility model relates to a kind of device that utilizes cylinder that the drag rope that twines is thereon carried out orderly folding and unfolding.

Background technology

At present, in the general drag rope draw off gear structure, the as a whole formula annulus of the collar, in case after the long-time operation of equipment, insufficient lubrication between the collar and the rotating shaft will cause swing arm to rotate with the rotation of rotating shaft, total system will be in havoc like this, and this integral type annulus is not easy to assemble.At first to hang the equipment of several tons of weights get off in the air from height, remove bearings at both ends, reductor and cylinder etc. again and just swing arm can be pulled down.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of collar dismounting is easy, the drag rope folding and unfolding in order, avoid the drag rope draw off gear of equipment disorder.

The technical scheme that provides according to the utility model, in rotating shaft, fixedly install cylinder, twine drag rope on the cylinder, be with the collar that is rotationally connected with it in outside, rotating shaft two ends, be connected with fork on the collar, be provided with pressure roller between the end of fork, the described collar or the anchor ear more than two are combined to form, and described fork is arranged on the cooresponding anchor ear.

The cylinder two ends are provided with the rib of projection.

Collar dismounting in the utility model is easy, and the drag rope folding and unfolding is orderly, avoids the equipment operation disorder.

Description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is a left view of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in Figure 1, 2: in rotating shaft 4, fixedly install cylinder 3, twine drag rope 6 on the cylinder 3, be with the collar 2 that is rotationally connected with it in outside, rotating shaft 4 two ends, be connected with fork 1 on the collar 2, be provided with pressure roller 5 between the end of fork 1, the described collar 2 is combined to form by the anchor ear more than two or two 7, and described fork 1 is arranged on the cooresponding anchor ear 7, and cylinder 3 two ends are provided with the rib 8 of projection.

Anchor ear 7 in the fork 1 and the collar 2 is welded into a whole swing arm, together is enclosed within the rotating shaft 4 with wire rope drum 3.Cylinder 3 rotates along with the rotation of rotating shaft 4, plays the purpose of folding and unfolding drag rope 6.Pressure roller 5 is housed on the fork, and it swung the effect that drag rope 6 prevents its disorder cable in the folding and unfolding process that compresses of playing by a small margin when rotating shaft 4 was rotated.This just requires to have relative motion between the collar 2 and cylinder 3 and the rotating shaft 4, and swing arm 1 can not be rotated with rotating shaft 4.The collar 2 in the utility model is combined to form by the anchor ear more than two or two 7, can or be connected through the hinge by bolted connection between each anchor ear 7, simultaneously its endoporus is enlarged, the collar 2 makes two semi-rings of anchor ear 7 as shown in Figure 1 and it is held tightly, make dismounting become very easy like this, swing also more actively.

Claims

1, a kind of drag rope draw off gear, comprise rotating shaft (4) and be fixedly installed on cylinder (3) in the rotating shaft (4), cylinder (3) is gone up and is twined drag rope (6), be with the collar (2) that is rotationally connected with it in rotating shaft (4) outside, two ends, be connected with fork (1) on the collar (2), be provided with pressure roller (5) between the end of fork (1), it is characterized in that: the described collar (2) or the anchor ear more than two (7) are combined to form, and described fork (1) is arranged on the cooresponding anchor ear (7).

2, drag rope draw off gear as claimed in claim 1 is characterized in that: cylinder (3) two ends are provided with the rib (8) of projection.
