Abstract

The utility model discloses a remote automatic butt joint, relates to a wind cooling joint used in a ladle smelting wind cooling system, and belongs to the ladle wind cooling facility technical field. The utility model aims to solve the problem that the high temperature ladle needs short distance contact when operated with wind cooling butt joint, and is easy to leak air and uncouple due to the lack of a lock-in device after butt joint. The utility model is composed of butt joint tubes which are matched and spliced with each other, a joint body and a self weight card, wherein, the tail end of the self weight card is movably connected with the butt joint tubes; a claw on the front end of the self weight card is clamped with a tail tube of the joint body. The self weight card can change the upper position and the lower position along with the rotation of the butt joint tubes, and can automatically overturn, unlock and clamp in under the self weight, and can be locked in the clamp-in position under the self weight after clamped in, thereby not only achieving remote operation of butt joint, ensuring the reliability and air tightness of the butt joint, but also having the obvious advantages of simple structure, convenient and simple butt joint. The utility model is applicable to butt joint appliances of ladle wind cooling tube.

Description

Far distance automatic butt joint

Technical field

The utility model relates in the smelting system, and the air-cooled joint of ladle air cooling system belongs to the air-cooled facility technology of ladle field.

Background technique

During ladle working, the spring maximum temperature in the ladle slide mechanism can reach 800 ℃, must the spring in the slide mechanism of ladle be remained on below 450 ℃ by air-cooled mechanism, to guarantee the normal operation of ladle slide mechanism.Lack the scientific and reasonable mode of fixedlying connected between the forced air cooled tube of air-cooled mechanism and the ladle slide mechanism, operator need emit high temperature closely to dock near ladle during connection, operating environment is abominable, labor intensity is big, dismantle length consuming time, the butt joint back is owing to lack locking setting, the phenomenon of wind or even disengagement appears running in air cooling system, cause the ladle slide mechanism to lose efficacy, thorn steel accident takes place, cause tremendous loss to production.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of far distance automatic butt joint for overcoming above-mentioned defective.

The alleged problem of the utility model realizes with following technological scheme:

A kind of far distance automatic butt joint, its unique distinction are, are provided with butt tube, fittings body, deadweight card that coupling is pegged graft in the formation, the tail end of deadweight card and butt tube flexible connection, the claw of front end and the tail pipe clamping of fittings body.

Above-mentioned far distance automatic butt joint, it is hinged that the tail end of described deadweight card passes through symmetrically arranged otic placode and bearing pin and butt tube both sides.

Above-mentioned far distance automatic butt joint, described claw are the arc claw to outer lug.

Deadweight card in the utility model can be flipped open with butt tube rotation transformation upper and lower position and under self-gravity action or snap in automatically, can under self-gravity action, be locked at again after snapping in and fix on the position, thereby both realized the remote-controlled operation of butt joint, the fixing and the tightness of butt joint have been guaranteed again, also have simultaneously simple in structure, dock remarkable advantage easily and fast, suitable butt joint utensil as the ladle forced air cooled tube uses.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is that half sectional view is looked on the left side of Fig. 1;

Fig. 3 is the utility model butt joint original state figure;

Fig. 4 is that the utility model deadweight snaps in procedure chart.

The component label is respectively in the accompanying drawing: 1-butt tube, 2-fittings body, 3-deadweight card, 4-claw, 5-tail pipe, 6-otic placode, 7-bearing pin, 8-hole seat.

Embodiment

Consult Fig. 1.The tail pipe 5 that fittings body 2 left ends are thinner is pegged graft with the import of ladle slide mechanism cold wind is connected, right-hand member is thicker grafting hole body and butt tube 1 coupling.Deadweight card 3 is tabular card, and two claws 4 vertically are positioned at front edge of board, plate tail end and butt tube 1 and flexibly connect.Retaining between two claws 4 apart from external diameter, extrusion L and the spliced eye of H 〉=tail pipe 5 to the Distance Matching between the tail pipe.

Still consult Fig. 1,2.Deadweight card 3 flexibly connects with butt tube 1 both sides by symmetrically arranged otic placode 6 and bearing pin 7, butt tube 1 both sides are provided with the hole seat 8 of coupling, two hole seats 8 are welded on the pipe face of butt tube 1, the outer end of two bearing pins 7 is welded on the pin shaft hole of two otic placodes 6 respectively, the inner insertion respectively in the pin shaft hole of two hole seats 8, and deadweight plate 3 can rotate for the axle center by bearing pin 7.Claw 4 has suitable free fall gravity to the structure length between the bearing pin 7 with deadweight card 3 and is advisable.

Still consult Fig. 1.Claw 4 is when the arc card of outer lug, the chucking point of contact is just divided up and down move, and strengthens fixing fixing.

Consult Fig. 1,2,3,4.Docking operation process of the present utility model is: rotate butt tube 1 and make deadweight card 3 be in lower position shown in Figure 3, deadweight card 3 outwards is flipped open under action of gravity automatically; Hold butt tube 1 Rotate 180 °, making deadweight card rotate to as shown in Figure 3 butt tube 1 directly over, at this moment, deadweight is stuck in action of gravity upset downwards automatically, two claws, 4 cards are to tail pipe 5 places of fittings body 2, when clicking into place fittings body 2 is fixed on butt tube 1, can accurately finish butt joint fast 5 meters distant places.
