Abstract

The utility model discloses a tool hoisting roller ring blanks by clamping the inner holes. A movable outer bushing (2) is sheathed in the middle of an inner fixing rod (1), the upper part of the inner fixing rod (1) is provided with a handle (3), and one end of the handle (3) is connected with the upper end of the outer bushing (2) by a pull rod (4). A plurality of movable hooks (5) capable of moving up and down are arranged on the lower part of the inner fixing rod (1), and the lower end of the outer bushing (2) is connected with the movable hooks (5) by a connecting rod. The utility model provides a special tool for hoisting roller ring blanks. The movable hooks can be adjusted according to the diameters of the inner holes of roller rings needed to be hoisted. The inner holes are clamped under the stretching action of the movable hooks, and the roller ring blanks can be hoisted. After the roller ring blanks are hoisted to positions, the handle is pressed down, and the roller ring blanks can be loosened by lifting up the movable hooks. The utility model has the advantages of convenient use, time saving, labour saving, high safety and high reliability.

Description

Roll collar workblank endoporus lifting tool

Technical field

The utility model relates to the lifting device that uses in a kind of roll production, especially a kind of roll collar workblank endoporus lifting tool.

Background technology

In the roll production during handling roll collar workblank owing to there is not proprietary instrument, all be to adopt the hook hook block or press from both sides with clamp, because temperature height, the volume of blank are big, weight is big, endoporus aperture size difference, all need two people to operate with hook hook or clamp folder, waste time and energy, and come off easily in the hoisting process, have hidden danger.

Summary of the invention

The purpose of this utility model is exactly in order to address the aforementioned drawbacks, and a kind of roll collar workblank endoporus lifting tool is provided, and uses the special tool of this handling roll collar workblank time saving and energy saving, safe and reliable.

The utility model roll collar workblank endoporus lifting tool is to be with movable outer tube at internal fixation bar middle part, the top of internal fixation bar is provided with handle, one end of handle links to each other with the upper end of outer tube by pull bar, the bottom of internal fixation bar is provided with several movable hooks that can rise and fall up and down, and the lower end of outer tube links to each other with movable hook by connecting rod.

As a kind of improvement of the present utility model, handle is provided with positioning and locking device.

As another improvement of the present utility model, movable hook is made as three.

When the utility model roll collar workblank endoporus lifting tool uses, size according to the roll collar inner hole of required lifting, suitable by circumference external diameter and roll collar inner hole footpath that fixed handle forms movable hook, under the effect that struts of movable hook, endoporus is blocked, roll collar workblank can be carried out handling, rely on the gravity of collars automatically movable hook to be pinned in the hoisting process.Press handle downwards after lifting puts in place, carry on the movable hook, can unclamp collars, very easy to use, time saving and energy saving, safe and reliable.
