Abstract
The invention discloses a hoisting tool for a ring-shaped part of a heat treatment pit furnace, which comprises a hoisting ring, wherein the hoisting ring is connected with a supporting beam through a connecting piece, the supporting beam is provided with a plurality of uniformly distributed end parts, and each end part is hinged with a lifting hook; and a manual lifting hook opening and closing mechanism for controlling the opening and closing of the lifting hook is also arranged on the supporting beam. The invention has the beneficial effects that compared with the existing hoisting tool: 1. although the structure is complex, the use is flexible and convenient, and the hook can be taken off and hooked by pulling the manual lifting hook opening and closing mechanism (realizing the operation outside the furnace); 2. the lifting hook can be hung on the outer circle or the inner circle of the ring piece by turning the adjusting ring; 3. and moving the adjusting rings to enable the adjusting rings to be positioned at the same-position positioning holes, and inserting the positioning pins to hoist the ring pieces with any size in the set range.
Description
Technical field
The present invention relates to a kind of lifting device, be 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 objective of the invention is for overcoming the deficiency of above-mentioned prior art, a kind of heat treatment well type stove circular piece lifting device is provided.
For realizing above-mentioned purpose, the present invention 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 a U type adjustable ring, and Open Side Down is sleeved on the end of rood beam for the U type ring of U type 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 invention has the beneficial effects as follows, with respect to existing lifting device:, spur manual suspension hook open-and-close mechanism and can pluck, link up with (realize stove operate) outward though 1 structure is complicated, flexible and convenient to use; 2, the upset adjustable ring can make 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.
