Abstract

The utility model relates to a winding drum of a winch for large-scale crane installation engineering, which comprises the winding drum, wherein rope grooves are formed on the surfaces of the left half part and the right half part of the winding drum, a steel wire rope is wounded in the left rope grooves, and another steel wire rope is wounded in the right rope grooves. The winding drum is characterized in that the left and right rope grooves adopt the structures of spiral grooves, and spiral lines of the left and the right spiral grooves are formed symmetrically. The utility model has the advantages as follows: the left and right rope grooves adopt the structures of spiral grooves, and the spiral lines of the left and the right spiral grooves are formed symmetrically, so that the steel wire ropes are wound around the winding drum in the spiral direction of the spiral grooves; and when the ropes are stretched, the axial force of two steel wire ropes to axle seats can cancel out each other, so as to ensure the stable stress of the axle seats and prolong the service life of the winch.

Description

A kind of goliath installation work lifting drum
Technical field
The utility model relates to a kind of winch, particularly a kind of goliath installation work lifting drum.
Background technology
Winch is a device of being finished traction work by manpower or mechanical powered drive reel, coiling rope.Can vertical-lift, level or inclination drag and draw weight.Winch is divided into two kinds of manual hoist and electric winchs, at present generally based on electric winch, it mainly is made up of electrical motor, plunging joint, drg, gear case and reel, be installed in jointly on the frame, be widely used in building, the material lifting or flat the dragging of hydraulic engineering, forestry, mine, harbour etc.
The goliath installation work adopts monovolume to the double-rope mode with lifting drum, reel is enclosed within on the anchor shaft between two axle beds, can rotate around anchor shaft, the left side of reel and right-hand part are wound with two steel ropes respectively, the rope outlet direction of two steel ropes is identical, during the lifting object, the rope stretching simultaneously of two steel ropes guarantees the balance of object.It exists shortcoming to be: since wire rope roll on reel the time winding direction asymmetric, the axle bed axial force to supporting drum during rope stretching constantly changes, stressed instability influences service life of winch.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of goliath installation work lifting drum of axle bed stability under loading.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of goliath installation work lifting drum, comprise reel, this reel left side and right-hand part surface are provided with grooving, are wound with steel cable respectively in described left grooving and the right grooving; It is characterized in that: described left grooving and right grooving are helical groove structure, and the helix line of this left-hand screw groove and right-hand screw groove is symmetrical arranged.
Advantage of the present utility model is: left grooving and right grooving are helical groove structure, and the helix line of this left-hand screw groove and right-hand screw groove is symmetrical arranged, steel rope is wound on the reel along the spiral fluted hand of spiral, during rope stretching, two steel ropes can be cancelled out each other to the axial force of axle bed, guarantee the axle bed stability under loading, improved winch service life.
Description of drawings
Accompanying drawing 1 is the utility model goliath installation work lifting drum structural representation.
The specific embodiment
As shown in drawings, comprise axle bed 1, anchor shaft 2, reel 3, left grooving 4, right grooving 5.
Above-mentioned a pair of axle bed 1 is fixed on the frame, be provided with anchor shaft 2 between the axle bed 1, be set with the reel 3 that rotates by motor-driven on the anchor shaft 2, these reel 3 left sides and right-hand part surface are provided with left grooving 4 and right grooving 5, left side grooving 4 and right grooving 5 are helical groove structure, and the helix line of this left-hand screw groove and right-hand screw groove is symmetrical arranged, and is wound with steel cable respectively in left grooving 4 and the right grooving 5.

Claims (1)
