Abstract
The utility model discloses a hoist roller. The hoist roller provided by the utility model is simple in structure and capable of effectively improving the hoisting height of a hoist. According to the technical scheme disclosed by the utility model, the hoist roller comprises a scroll and a wire rope; the end part of the wire rope is fixed at the middle part of a scroll; spiral grooves are arranged in the scroll; the spiral grooves are symmetrically distributed at two sides of the scroll center, and the spiral directions of the spiral grooves at different sides are opposite. The hoist roller is reasonable in structure, can effectively improving the hoisting height of the hoist, thereby facilitating the indoor use of a bridge-type or portal crane.
Description
Technical field:
The utility model relates to hoisting crane, particularly a kind of reel that is applicable on the hoisting crane.
Background technology:
Present bridge-type, when the lifting altitude of transfer crane need increase; The general individual layer winding method that strengthens drum diameter that all adopts increase lifting altitude, but the environment for use of hoisting crane is indoor sometimes; User's factory building height is limited; If adopt the reel that has strengthened diameter, just can't be adapted to the restriction of environment for use, bring a lot of inconvenience for user's hoisting crane use.
Summary of the invention:
The purpose of the utility model is that design is a kind of simple in structure, can effectively increase the hoist roller of crane hoisting height.
The technical scheme of the utility model is, a kind of hoist roller, and it comprises spool, steel rope is characterized in that: the end of steel rope is fixed on the middle part of spool, on spool, has plug helix.Said plug helix is the symmetrical distribution that branch is listed in both sides, spool center, and the spiral fluted hand of spiral of homonymy is not opposite.
The utility model is rational in infrastructure, can actv. upgrades the lifting altitude of heavy-duty machine, is convenient to the indoor use of bridge-type, transfer crane.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Describe embodiment in detail in conjunction with accompanying drawing, the specific embodiment of the utility model is a kind of hoist roller; It comprises spool 1; Steel rope 3, the end of steel rope is fixed on the middle part of spool, on spool, has plug helix 2; The described plug helix of present embodiment is the symmetrical distribution that branch is listed in both sides, spool center, and the spiral fluted hand of spiral of homonymy is not opposite.The utility model in use, after reel was rolled, the innermost layer steel rope was rolled to both sides by the centre along the plug helix on the reel; When after expiring, because the end wall effect, steel rope is rolled to midway location by two ends again; Like this when steel rope finally be in the end position that hoists the time, steel rope receive force direction vertical, the stressing conditions that tiltedly draws is less; Protected the service life of steel rope effectively, can promote the indoor use height of bridge-type, transfer crane, suitable environment is more extensive.
Claims (2)
1. hoist roller, it comprises spool, steel rope is characterized in that: the end of steel rope is fixed on the middle part of spool, on spool, has plug helix.
2. a kind of hoist roller as claimed in claim 1 is characterized in that: said plug helix is the symmetrical distribution that branch is listed in both sides, spool center, and the spiral fluted hand of spiral of homonymy is not opposite.
