Abstract
The invention relates to a semi-gear special sling used in the mechanical element heat treatment technique, comprising a main beam, an auxiliary beam, an adjuster, a adjust rod, a adjust sheath, a compression spring, bearing, a adjust axle, a hook, and a hook chain. The adjustor of main beam is formed by mounting the long axle, round nut, baffle plate on the middle-upper part of adjustor; mounting the adjust rod, bearing, compression spring and adjust sheath on the upper part of adjustor while fixing them with long bolt, nut and baffle plate; mounting the adjust axle in the hole of central beam of adjustor which is fixed by slotted nut and slotted bolt; each one end of four hook chains is mounted on the main and auxiliary beams, and after mounting the adjustor of main beam on the main beam, adjusting the compression spring of adjust sheath, to move upwards the main beam adjustor under the elastic force of compression spring, until the adjust axle in the center of beam hole. The invention can meet the demand of large-scale gear including littler quench distortion, uniform rigidity, better safety, and higher producing efficiency.
Description
Technical field: the present invention relates to a kind of half body gear dedicated sling in the component of machine thermal treatment process technology field.
Background technology: at present, diameter quenches greater than large-scale half body gear more than 5 meters, adopts Technologies for Heating Processing such as integral quenching, induction hardening, flame hardnessing at present usually.Half body gear does not have special hanger and adopts chain that gear is erected and hang down quenching again, be out of shape wayward, poor stability, batch is little, the incompatibility batch manufacturing.Can not satisfy the application request of half body gear fully.Therefore develop a kind of half body gear dedicated sling and be always state's new problem to be solved of having to go to the toilet.
The purpose of this invention is to provide a kind of design science, technology is easy to manufacture, the employing half body gear dedicated sling quenches, whole quenching technical process operation is easy, control flexibly, can satisfy the gear quenching technological requirement preferably, improved product design, the distribution of hardness is milder, overcome the hardness inequality that original quenching mode is brought, deflection is big, the shortcoming that batch is little, make the part overall performance reach higher level, use a kind of half body gear dedicated sling in this type component thermal treatment process technology field widely.
Summary of the invention: the object of the present invention is achieved like this: whole device is by support, chain sling, girder, suspension hook, counterweight, auxiliary girder, the suspension hook ring, catch, circular nut, adjusting shaft, nut, regulator body, regulating sleeve, adjust bar, stage clip, overbolt, major axis, fluted nut, spring cotter, minor axis, bearing, the dish spring, the suspension hook seat is formed, the girder regulating control is at regulator body middle and upper part dress major axis, circular nut, catch, debug pole on regulator body top, bearing, stage clip, regulating sleeve, and use overbolt, nut, catch tightens up it, debug nodal axisn in the middle part beam body opening on regulator body, and use fluted nut, spring cotter tightens up it, and at regulator body bottom dress suspension hook ring, and use minor axis, circular nut, catch tightens up it; The auxiliary girder regulating control is at regulator body middle and upper part dress major axis, circular nut, catch, debug pole, bearing, stage clip, regulating sleeve on regulator body top, and it is tightened up with overbolt, nut, catch, debug nodal axisn in the middle part beam body opening on regulator body, and it is tightened up with fluted nut, spring cotter, and at regulator body bottom dress suspension hook seat, dish spring, and it is tightened up with minor axis, circular nut, catch; One end of four chain slings is separately fixed on girder, the auxiliary girder, suspension hook is hung on suspension hook ring, the suspension hook seat, counterweight is contained in the left end of auxiliary girder, support is contained in below the girder, after installing to girder regulating control integral body on the girder, twist the regulating sleeve compression press spring,, be adjusted to adjusting shaft and just in time be just in time in the centre of beam body opening in that whole being with on the suspension hook of girder regulating control moved; After installing on the auxiliary girder, twist the regulating sleeve compression press spring to auxiliary girder regulating control integral body,, be adjusted to adjusting shaft and just in time be just in time in the centre of beam body opening in that whole being with on the suspension hook of auxiliary girder regulating control moved.Dish spring below the auxiliary girder regulating control can not be regulated initial pressure; Whole device is made up of chain sling, girder, suspension hook, auxiliary girder, catch, circular nut, adjusting shaft, regulator body, major axis, fluted nut, spring cotter, minor axis, roll sleeve, regulating control is at regulator body middle and upper part dress roll sleeve, major axis, circular nut, catch, debug nodal axisn in the middle part beam body opening on regulator body, and it is tightened up, and under regulator body, it is tightened up with minor axis, circular nut, catch with fluted nut, spring cotter; One end of four chain slings is separately fixed on girder, the auxiliary girder, suspension hook is hung on the regulator body bottom, spring cotter and fluted nut on the adjusting shaft are unloaded in the use of regulating control earlier, extract adjusting shaft out, movement governor and with below suspension hook, for laborsaving, should push away the top of regulating control as best one can, the effect of the roll sleeve on the major axis plays rolling action when being movement governor, regulating control is put on adjusting shaft after being transferred to the position, puts on fluted nut and spring cotter then.
Main points of the present invention are its structure and principle of work.Its principle of work is, the half body gear dedicated sling quenching technical to satisfy lifting steadily, go into the cooling system conditioner time when quenching and will lack.The using method of embodiment one suspender, at first according to half tooth that is hung, calculate or estimate the center of half tooth, the preliminary position of adjusting chain rigging and suspension hook, if suspender tilts very much when unloaded, can adjust counterweight, half body gear is sling slightly, degree of dip according to half body gear is adjusted suspender again, adjusts counterweight simultaneously.The weight of counterweight and position all can be adjusted.If heated half body gear is hung in plan, these adjustment must not carried out before half body gear heats.The using method of embodiment two suspenders is at first determined the Position Approximate that suspender is placed according to the size of half body gear, determines the suspension hook position according to this position, and the suspension hook position is adjusted.Examination is hung then, and the adjustable bolt according on direction of tilt and the degree adjustment rigging till level behind half tooth of slinging, does it again if adjusted, need be readjusted the suspension hook position to the limit.
Half body gear dedicated sling compared with prior art, has the design science, technology is easy to manufacture, the employing half body gear dedicated sling quenches, can satisfy diameter greater than the quality that is beyond one's reach of large gear part integral quenching more than 5 meters, other lifting quenching modes are a kind of very superior and practical heat-treatment quenching modes relatively, whole quenching technical process operation is easy, control flexibly, can satisfy the requirement of large-scale half body gear quenching quality preferably, improved product design, the distribution of hardness is more even, it is big to have overcome the distortion that original quenching mode brings, hardness is inhomogeneous, poor stability, the few shortcoming of batch, make the part overall performance reach higher level, advantages such as capacity rating is enhanced about more than once will be widely used in the large-sized mechanical components thermal treatment process technology field.
