Abstract

The invention discloses a scroll hoisting tool, which comprises a mandrel, wherein a hoisting ring is connected above the mandrel; the lower end part of the mandrel is connected with a rotary table body; a sleeve which is matched with a core pipe inner hole on the inner side of the scroll is sleeved on the outer side of the mandrel; the lower end part of the sleeve is connected with arc-shaped expansion sheets through connecting rings; and the arc-shaped expansion sheets are arranged symmetrically. Before hoisting, the scroll hoisting tool is placed into a core tube on the inner side of a scroll, the mandrel is hoisted upwards by using hoisting equipment, and the expansion sheets expand towards the outer side under the action of the rotary table body during upward movement, so that the hoisting tool is fastened integrally with the scroll and can be hoisted together with the scroll simultaneously; and after falling, upward tensile force of the mandrel is released, the mandrel can be moved downwards in a manner relative to the sleeve, the expanding force on the expansion sheets is released simultaneously, and the hoisting tool is taken out. The scroll hoisting tool is simple in overall structure, is convenient to operate, and is safe and reliable.

Description

The paper roll lifting tool

Technical field

The present invention relates to a kind of lifting tool, particularly a kind of paper roll lifting tool.

Background technology

Printing industry often need be loaded and unloaded lifting operation with toilet roll at present, and there is a core pipe inboard of paper roll, and paper is wrapped in the core pipe and forms paper roll outward.Inconvenient when utilizing the lifting of fork truck or other hanging devices, big portion utilizes rope to cooperate suspension hook to carry out, and does not have potential safety hazard simultaneously.

Summary of the invention

The purpose of this invention is to provide that a kind of integral structure is simple, the lifting paper roll is convenient, safe and reliable, the paper roll lifting tool of high efficiency, overcome the deficiency of prior art.

Paper roll lifting tool of the present invention; Comprise mandrel; The top of mandrel is connected with suspension ring, is connected with Rotary-table in the bottom of mandrel, and the outside of mandrel is set with the sleeve that matches with the inboard core pipe orifice of paper roll; The bottom of sleeve is connected with the bloated sheet of arc through coupling link, and the bloated sheet of arc is symmetrical set.

Paper roll lifting tool of the present invention can put it into before lifting in the inboard core pipe of paper roll, utilizes the lifting appliance mandrel of upwards slinging; The outside side stay of bloated sheet is expanded under the effect at Rotary-table when last moving, and this suspender and paper roll are fastened as one, and can be sling simultaneously; Following fall behind removed mandrel to upper pulling force; Mandrel can move down with respect to sleeve, has removed the support expansive force to the sheet that expands simultaneously, takes out this lifting tool and gets final product.Integral structure is simple, and is easy to operate, safe and reliable.

Description of drawings

Fig. 1 is the structural representation of the specific embodiment of the invention;

Fig. 2 is the structural representation of sleeve shown in Figure 1.

The specific embodiment

Like Fig. 1, shown in 2: 1 is mandrel, and the top of mandrel 1 is connected with the suspension ring 5 that are used to lift through engage thread.Be connected with Rotary-table 2 in the bottom of mandrel 1, Rotary-table 2 is structure as a whole with mandrel 1.The outside of mandrel 1 is set with sleeve 3, and the bottom of sleeve 3 is connected with the bloated sheet 4 of arc through coupling link 6, and the bloated sheet 4 of arc is symmetrical set.

Before lifting, can this suspender be put into the inboard core pipe of paper roll, utilize the lifting appliance mandrel of upwards slinging, the outside side stay of bloated sheet is expanded under the effect at Rotary-table when last moving; This suspender and paper roll are fastened as one; Can be sling simultaneously, following backwardness removed mandrel to upper pulling force, mandrel can move down with respect to sleeve; Removed support expansive force simultaneously, taken out this lifting tool and get final product the sheet that expands.Integral structure is simple, and is easy to operate, safe and reliable.
