Abstract

The utility model discloses a switch rail quenching device, comprising a movable trolley provided with a movable bracket, and an n-shaped frame group provided with a heating device and a cooling device. The movable bracket is provided with a lifting support block whose upper part forms a groove shape; the interior of the groove is embedded with insulation material and metal material; one end of a conducting wire is threaded through the support block and is connected with the insulation material and the metal material, and the other end of the conducting wire is connected with a control device through which the lifting of the support block is controlled. The trolley is also provided with a swing device, and the n-shaped frame is provided with a follow-up mechanism.

Description

The Switch quenching device

The utility model belongs to metal heat treatmet equipment, relates in particular to a kind of quenching device of rail induction heating.

Rail is the vitals of railway top-out, and tongue also belongs to one of important accessory on the railway, is mainly used in turnout switch, and tongue is a kind of tapered rail.In order to improve intensity and toughness, all require to carry out quench treatment.In existing Switch quenching technology, tongue is placed on the liftable roller-way, carry tongue to heat, cool off by roller-way.The Deformation control of tongue is controlled by the operator in thermal treatment.Promptly by manually with observing and experience hand-operated lifting roller-way, to adapt to the distortion in the rail thermal treatment.This certainly will make workman's troublesome poeration, complexity, and tongue distortion simultaneously is also unstable, makes the alignment workload after the quenching big.

The purpose of this utility model is the deflection behind the minimizing hardening of rails, improves operant level.

For achieving the above object, the design of the utility model employing is: the Switch quenching device, it comprises the removable chassis that travel(l)ing rest is housed and the door type frame group of heating unit and refrigerating unit is housed respectively.Liftable tray is housed on travel(l)ing rest, and the top of tray is flute profile, studs with insulating material and metallic substance in the groove, and an end of lead passes tray and insulating material and metallic substance and joins.The other end of lead links to each other with control tray lifting control device.

Pendulous device also is housed on chassis, and pendulous device is made up of oscillating roller, lifting device, framework and fixed pivot.One end of framework links to each other with fixed pivot, and the other end is equipped with oscillating roller.One end of lifting device is connected with fixed pivot.The other end and framework a part except that two-end-point is hinged.

Gap a=10～the 30mm of tray and travel(l)ing rest, its gap commonly used is 11.5 and 23mm, and allows this gap to adjust.

Adopt the utility model can bring following effect:

Owing to adopted tray, can reduce the deflection that Switch quenching is handled.And can realize control automatically, simple to operate.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 tray installation plan

The A of Fig. 2 Fig. 1-A sectional drawing

Fig. 3 pendulous device installation plan

Fig. 4 contains the door type framework of slaving mechanism

In the accompanying drawings, tray 1 is installed on the travel(l)ing rest 2, according to the tongue model difference of handling, the adjustable position of piece 1 in travel(l)ing rest 2 that put one's child in a boarding nursery.Setting range is at a=10～30mm.Insulating material 4 and energy conductive metallic material 3 are housed in the upper grooves of tray 1, lead 5 passes tray 1 and is connected with metallic substance 3 with insulating material 4, the power set that this tray 1 of the other end of lead 5 and control rises or descends links to each other as cylinder, hydro-cylinder or electric device.In Fig. 3, an end of framework 8 links to each other with fulcrum 7, and framework 8 can rotate around fulcrum 7, and the other end of framework 8 is equipped with oscillating roller 9, and oscillating roller 9 can rotate around the axis of self.One end of cylinder 6 is connected with fulcrum 10, and cylinder 6 can rotate around fulcrum 10, and certain in the other end of cylinder 6 and the framework 8 a bit links to each other, and the position of tie point requires definite by the adjustable height of oscillating roller 9.In Fig. 4, column 12 is contained on the crossbeam of type framework 13, and column can slide on crossbeam, in the lower end of column 12 universal joint 11 is housed, the heating unit (or refrigerating unit) of universal joint 11 bottoms can swing according to the raw material condition of tongue, moves up and down.

The working process of said apparatus is such, is placed on the tongue on the chassis, will deform in heating and quenching, and front end is curved down.During tray on running into chassis, circuit is connected, and tray then descends, and throws off rail; Tray and tongue one are thrown off, and then circuit disconnects, and tray stops to descend, and when tongue contacted with tray once more, tray descended again.When tongue runs on the pendulous device, because the supporting role of oscillating roller has reduced the distortion that causes because of the tongue deadweight.
