Description

A kind of novel shaft furnace suspender
Technical field
The utility model relates to a kind of suspender, is specifically related to a kind of shaft furnace suspender that is used to carry workpiece in heat treatment process.
Background technology
The structure of shaft furnace is a cylindrical furnace, reaches tens meters because of what the degree of depth of the demand body of heater of workpiece length had; And the shaft furnace suspender is an indispensable loading and unloading carrier in the heat treatment of workpieces process.Present existing shaft furnace suspender generally includes base and is installed in suspension rod on the base.In the heat treatment of workpieces process, the base of shaft furnace suspender and suspension rod need together enter in the shaft furnace after heat treatment of workpieces is finished in company with workpiece, and workpiece is being hung out.Present shaft furnace suspender very easily produces distortion because its base and suspension rod need be gone into stove heating, the cooling of coming out of the stove repeatedly in company with workpiece; Especially its shaft is long for suspension rod, intensity is low than base, and the suspension rod that is in after heat treatment is finished under the condition of high temperature especially is easy to generate necking down, fracture in handling workpiece process; Particularly in the darker shaft furnace of the degree of depth, because the shaft of suspension rod lengthening is more prone to produce the problem of necking down, fracture; In case and suspension rod produces not only suspender itself damage easily of rupturing; But also damage shaft furnace easily and produce potential safety hazard.With respect to base, suspension rod not only is more prone to be damaged in the shaft furnace suspender, in case and suspension rod to be damaged the consequence of generation also more serious.
For example, Chinese patent publication number CN102051463A, in open day on May 11st, 2011, the name that utility model is created is called the shaft furnace suspender, and it is made up of suspension rod, the radial base of irregular honeycomb, bending block; By suspension rod is connected with the radial base of irregular honeycomb, form the complete shaft furnace suspender of a cover.Though the shaft furnace suspender of this application case has improved the problem of bottom deformation to a certain extent by the bending block structure, but because in the heat treatment of workpieces process, the base of the shaft furnace suspender of this application case and suspension rod need together enter in the shaft furnace in company with workpiece and finish until heat treatment of workpieces, thereby the suspension rod that the suspension rod of the shaft furnace suspender of this application case is in after heat treatment is finished under the condition of high temperature is easy to produce the problem of necking down, fracture equally in handling workpiece process.
The utility model content
The purpose of this utility model is need together enter together heating in the shaft furnace in company with workpiece for the suspension rod that overcomes shaft furnace suspender in the prior art, in the hot place of workpiece process, especially handling workpiece process middle hanger is easy to generate the problem of necking down, fracture after heat treatment of workpieces is finished; Provide a kind of and can effectively solve in the hot place of workpiece process, especially handling workpiece process middle hanger is easy to generate the problem of necking down, fracture after heat treatment of workpieces is finished, and improves the service life of shaft furnace suspender and the shaft furnace suspender of processing safety.
The technical solution of the utility model is:
A kind of novel shaft furnace suspender comprises base and suspension rod, and the top at described base middle part is provided with stay bearing plate, is provided with some support limit stops that are connected stay bearing plate and base between stay bearing plate and the base; Described stay bearing plate middle part is provided with the lifting through hole, and this lifting through hole edge is provided with some circumferentially uniform breach; Described support limit stop and has at least in each support limit stop and has a side B on the support limit stop and be in the same plane with the side C of a breach wherein between adjacent two breach; Described suspension rod lower side is provided with and the corresponding supporting lug of above-mentioned breach; Described base is suspended on the supporting lug of suspension rod by stay bearing plate.
This programme has carried out the split design with base and suspension rod, the more important thing is at the bottom of suspension rod is hung base shaft furnace after, do not participate in the hot-cured process thereby suspension rod can be separated with base suspension rod taken out; After heat treatment of workpieces was finished, suspension rod can stretch in the shaft furnace again and the base amalgamation, and base and workpiece are together hung out; Thereby can effectively the solving in the hot place of workpiece process of the shaft furnace suspender of this programme, especially handling workpiece process middle hanger is easy to generate the problem of necking down, fracture after heat treatment of workpieces is finished, and improves the service life and the processing safety of shaft furnace suspender.
On the other hand, the support limit stop of this programme not only plays the effect of support, connection base and stay bearing plate; The more important thing is owing to have and have a side on the support limit stop and be in the same plane with the side of a breach wherein, when the rotation suspension rod make suspension rod separate with base in the process, this side of this support limit stop will be as the reference plane of supporting lug, in case suspension rod rotates to supporting lug when being resisted against this side of this support limit stop, suspension rod can be separated with base; And then the lock out operation that guarantees suspension rod and base can be realized by failure-free.
As preferably, suspension rod comprises and hangs head and pipe link that described supporting lug is arranged on and hangs on the side; Be provided with middle through hole in the described pipe link, described upper surface of hanging head is provided with mounting hole, and the mounting hole lower end closed; The lower end of described pipe link is plugged in the mounting hole, and described hanging between a upper surface and the pipe link connects by being weldingly connected; Described mounting hole and middle through hole form the refrigerant fluid storage chamber that is used to store refrigerant fluid of upper end open, lower end closed in suspension rod.
Because need together entering in the shaft furnace in company with workpiece, the base of shaft furnace suspender of the prior art and suspension rod finish until heat treatment of workpieces; Thereby it is in order to improve the intensity of suspension rod, reduce suspension rod in the hot place of workpiece process as far as possible, especially the problem that after heat treatment of workpieces is finished, occurs necking down, fracture in the handling workpiece process, existing suspension rod is generally the moulding of one processing and fabricating, avoid structure as far as possible, avoid the connection structure of weld seam in the process of high temperature heating destroyed by welding splicing; The manufacture difficulty and the cost of manufacture of suspension rod have so just been increased greatly.On the other hand, owing to suspension rod need together be heat-treated with workpiece, in order to guarantee the stable, reliable of heat treatment environment; Thereby can't design the scheme that some cool in the present suspension rod, in heat treatment process, reduce the temperature of suspension rod.
