Abstract

The utility model discloses a hoisting tool for a circle piece of a heat treatment pit furnace. The hoisting tool comprises a hoisting ring; the hoisting ring is connected with a supporting beam through connection pieces; the supporting beam is provided with a plurality of uniformly-distributed end parts; a hoisting hook is respectively hinged with each end part; and a manual hoisting hook opening and closing mechanism for control the opening and closing of the hoisting hooks is further arranged on the supporting beam. Compared with the conventional hoisting tool, the hoisting tool provided by the utility model has the beneficial effects as follows: 1, although the hoisting tool is more complex in structure, the hoisting tool is flexible and convenient to use, and the hoisting hooks can be taken off and hung by pulling the manual hoisting hook opening and closing mechanism (operations outside the pit furnace can be realized); 2, the hoisting hooks can be hung at the outer circle or the inner circle of the circle piece by overturning adjusting rings; and 3, the adjusting rings are moved to be located in positioning holes at the same position; and any circle piece with a random size can be hoisted within a set range by inserting position pins.

Description

Heat treatment well type stove circular piece lifting device

Technical field

The utility model relates to a kind of lifting device, is specifically related to a kind of lifting device that is applicable to heat treatment well type stove circular piece.

Background technology

Shaft furnace is the heat treatment equipment of big machinery part and parts, and the shaft furnace suspender is wherein indispensable loading and unloading carrier.Existing lifting device is as shown in Figure 1, is made up of suspension ring 4, lifting chain 5 and suspension hook 2, and three suspension hooks 2 connect lifting chain 5 respectively, and the upper end of lifting chain 5 is connected with suspension ring 4.Hand-held suspension hook 2 is plucked, is linked up with during use, realizes the hook at suspension ring spare 1.This tool construction is simple, use flexibly, but the deficiency that exists mainly is: one but must hand suspension hook and pluck, link up with, and in stove, can not realize decoupling device, hook; Two, suspension hook can only hang on the outer rim of ring, and is inapplicable for some circular piece that is suitable for hanging on the inner edge.

Summary of the invention

The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, a kind of heat treatment well type stove circular piece lifting device being provided.

For realizing above-mentioned purpose, the utility model adopts following technical proposals:

A kind of heat treatment well type stove circular piece lifting device, it comprises suspension ring, and suspension ring link to each other with support beam through attaching parts, and support beam has a plurality of well-distributeds end, the hinged suspension hook in each end; Also be provided with the manual suspension hook open-and-close mechanism of control suspension hook folding on the support beam.

Said manual suspension hook open-and-close mechanism comprises the pull bar that passes supporting seat middle part, the linking to each other of the coupler body of the lower end of pull bar through little attaching parts and said suspension hook; The upper end of pull bar connects lever one end, and the middle part of lever links to each other with fixing bearing, and the other end of lever connects a manual pull bar.

Said attaching parts is the lifting chain, and said support beam is a rood beam, and the lifting chain is 4, and its lower end is respectively the end that is hinged on rood beam.

The end of said support beam is hinged through adjustable ring and suspension hook, and the end of support beam is provided with several knock holees, and adjustable ring can be free to slide and be provided with the hole of matching with said knock hole along the end, and through the locating dowel pin location.The hook portion direction of adjustable ring lower end suspension hook is one, so when the installation direction of upset adjustable ring, the direction of the hook portion of suspension hook also changes, and is applicable to the circular piece under the adjustment different situations thereupon.

Said adjustable ring is the U-shaped adjustable ring, and Open Side Down is sleeved on the end of rood beam for the U type ring of U-shaped adjustable ring.

Said little attaching parts is little lifting chain.

Said bearing is fixed on the support beam.

" rectangular distribution " refers to that the multidigit end is positioned at the upper mutual angle of same horizontal surface and equates, helps the circular piece of slinging.

Working process: adjustable ring can be free to slide along the end of support beam, locatees with locating dowel pin after adjusting to the appropriate location.During use downwards pulling manual draw bar suspension hook inwardly receive with; Unclamp manual draw bar, the suspension hook by gravity is opened automatically, thereby realizes hook and decoupling device.When the hook portion of suspension hook stretched out, drop-down manual draw bar was realized decoupling device, unclamped manual draw bar and realized hook; When the hook portion of suspension hook extended internally, drop-down manual draw bar was realized hook, unclamped manual draw bar and realized decoupling device.

The beneficial effect of the utility model is, with respect to existing lifting device: though 1 structure is complicated, flexible and convenient to use, spurs manual suspension hook open-and-close mechanism and can pluck, link up with (realize stove operate) outward; 2, the upset adjustable ring promptly suspension hook hang over the cylindrical or the interior circle of ring; 3, move adjustable ring, make many adjustable rings be in coordination knock hole place, plug locating dowel pin, can lift any big or small ring in the setting range.
