Abstract

The utility model discloses a circular ring sling in the field of slings. The circular ring sling comprises a suspension seat, wherein a suspension lug is connected to the upper side of the suspension seat; three cross beams are uniformly distributed at the periphery of the suspension seat; lead screws are arranged in the cross beams; clamping motors are fixed on the cross beams and are in transmission connection with the lead screws; clamp arms are correspondingly sleeved on the cross beams; the clamp arms and the cross beams are connected in a sliding mode; clamp openings for being bent in the direction of a central line of the suspension seat are formed at the lower ends of the clamp arms; and nuts which are in threaded engagement with the lead screws are arranged on the lead screws and are fixed with the corresponding clamp arms. During operation, the circular ring sling rotates by virtue of the clamping motors and can be used for driving the clamp arms to be expanded or tightened; when a circular workpiece is placed on the inner sides of the clamp openings, the clamp arms are used for tightening the circular workpiece to insert the clamp opening positions into the lower side of the periphery of the workpiece, the suspension lug is hoisted, and the workpiece is fallen on the clamp openings and is hoisted so as to avoid being hurt, and the circular workpiece can be conveniently hoisted. The circular ring sling is particularly suitable for hoisting the circular workpiece at the high temperature, and the surface of the workpiece can be prevented from being damaged.

Description

The annulus suspender

Technical field

The utility model relates to a kind of suspender, particularly a kind of suspender for handling annulus workpiece.

Background technology

A kind of annular frame suspender is disclosed in the Chinese patent database, application number: 201110267385.4, the applying date: 2011-09-09, open day: 2012-01-18, it is made up of framework, briquetting and bolt; Described framework is the annular arrangement rigid member, uniform at least 3 screws radially on the framework circumference, and framework outer wall top captive joint rectangle flap seat, the flap seat top is provided with suspension ring between two parties; Ecto-entad screws in the radially screw of described bolt from the framework outer wall; Briquetting is the plane circular arc-like block, and its lateral cross section is dihedral, and briquetting male part and bolt end screens connect and compose radially linkage structure.This installs workpiece loading and unloading nearby, owing to adopt the high spiral clamping structure of reliability, guarantees charge and discharge operations safety, and labour intensity is low, and external annular frame has the guard shield effect, when avoiding lifting workpiece takes place and lathe collides with.The present invention is fit to the lifting of big gear of batch manufacturing and disc-like part.Its weak point is: this device for mechanical degree is low, needs on-the-spot swivel bolt that workpiece is clamped, and operates cumbersome.

In the prior art, be used for the suspender of the workpiece of handling annular, generally annular workpieces need be erected, carry out handling with suspension hook, steel rope etc. then, it is not suitable for the handling of the workpiece that still is in high temperature.

The utility model content

The purpose of this utility model provides a kind of annulus suspender, horizontal handling annulus workpiece easily, surface of the work zero damage.

The purpose of this utility model is achieved in that a kind of annulus suspender, comprises flap seat, and the flap seat upside is connected with hanger, described flap seat periphery is evenly equipped with three crossbeams, in the described crossbeam screw mandrel is installed, clamping motor is fixedly arranged on the crossbeam, clamping motor and screw mandrel are in transmission connection; Correspondence is set with tong arm on the crossbeam, sliding block joint between tong arm and the crossbeam, and the tong arm lower end is provided with to the jaw of flap seat center line direction bending; Described screw mandrel is provided with the nut with the wire rod thread engagement, and described nut fixes with corresponding tong arm.

During work, rotate by clamping motor, can drive screw mandrel rotates, screw mandrel drives the nut displacement, and nut drive tong arm opens or tightens up, when the annular arrangement workpiece is placed on the jaw inboard, tong arm tightens up and jaw position can be inserted into workpiece periphery downside, at this moment, the lifting hanger, workpiece drops on the jaw and is lifted.Compared with prior art, circumferentially blocking workpiece, by the jaw supporting workpiece, workpiece originally is in outside the antagonistic force of deadweight the utility model, is not subjected to other squeese pressure by tong arm, and workpiece can not crushed, easily handling annular arrangement workpiece.The utility model is particularly useful for the annular arrangement workpiece of handling high temperature, can guarantee the surface of the work zero damage.

For guaranteeing that tong arm is unlikely to press from both sides bad workpiece, simultaneously, also in order to protect motor, described clamping motor is connected with drive sprocket through torque limiter, and driven sprocket is fixedly arranged on the screw mandrel, is connected through chain between drive sprocket and the driven sprocket.

As further improvement of the utility model, be provided with the tactile stop mechanism that the corresponding clamping motor of control stops near jaw position on the described tong arm, tactile stop mechanism is arranged between high temperature resistant pressing plate and the tong arm.

For guaranteeing that slip is smooth and easy between tong arm and the crossbeam, the location is reliable, upside and the downside of described crossbeam are provided with guide plate, are positioned at two guide plates outside correspondence on the tong arm and are provided with slide block.
