Abstract

The utility model discloses a fast take-off device. A bearing is arranged at a front end of a fast joint (4). The utility model is characterized in that a dead ring (6) is sleeved on the bearing of the fast joint, a tightening lead screw (5) is passed through a dead hole of the dead ring (6), and the dead ring (6) is fixed with a pallet steel (7) used rotating pin (3) with a handle (8). The utility model is characterized by convenient application, safety, simple structure and small possibilities to burn operators.

Description

Quick taker
(1). technical field
The utility model belongs to the steelmaking equipment field, particularly a kind of device that is used for connecting on the ladle tunger tube.
(2). background technique
Metallurgical industry is in refining process, need be blown into argon gas (in metallurgy industry, being called Argon), composition and temperature with even molten steel, get rid of slag inclusion and gas, be provided with the connecting head of tunger tube in the side of ladle for this reason, be used for when needs carry out Argon to molten steel, being connected, after Argon finishes, again tunger tube taken off with tunger tube.Present being connected or taking off of tunger tube and ladle connecting head, adopt and manually hand tunger tube and be connected with the connecting head of ladle side or take off.Owing to connecing, getting in the process, there are molten steel or slag to spill often, burn easily operator and generation accident from ladle.
(3). summary of the invention
The purpose of this utility model provides a kind of quick taker.It is easy to use, safe, and is simple in structure, and the operator's that do not burn characteristics are arranged.
For reaching above-mentioned purpose, the front end of the utility model rapid pipe joint is provided with bearing, it is characterized in that retaining ring is enclosed within on the bearing of rapid pipe joint, and the hole that screw mandrel passes on the retaining ring is fastening with tightening, and retaining ring is fixed with rotating dog with the steel fork that has handle.
The front end of steel fork is provided with through hole, and retaining ring and steel fork corresponding position are provided with through hole.
Rotating dog passes eyelet welding on steel fork and the retaining ring and connects and be fixed on the retaining ring.
The utility model is owing to be fixed with retaining ring on the bearing of rapid pipe joint, retaining ring is connected with the steel fork that has handle, as long as pulling handle, can be easily rapid pipe joint is connected with joint on the ladle or from the ladle joint, it is taken off, again because the rear end of rapid pipe joint is connected with the argon pipe, therefore can be from connecing, get the argon pipe easily from the ladle larger distance, and the operator that can not burn significantly reduce accident.
Below in conjunction with accompanying drawing the utility model is described further.
(4). description of drawings
Fig. 1 is a structure diagram of the present utility model.
(5). embodiment
Referring to Fig. 1.The front end of rapid pipe joint 4 is provided with bearing, and bearing can slide front and back, and the rear end is connected with argon pipe assembly 9.Retaining ring 6 is enclosed within on the bearing of rapid pipe joint, the hole that screw mandrel 5 passes on the retaining ring 6 is fastening with tightening, the front end of steel fork 7 is provided with through hole, and retaining ring 6 is provided with through hole with steel fork 7 corresponding positions, and rotating dog 3 passes eyelet welding on steel fork 7 and the retaining ring 6 and connects and be fixed on the retaining ring 6.
When ladle needs Argon, operator hold handle 8 joint 2 fixing on the ladle 1 are aimed in rapid pipe joint 4, because the bearing in the rapid pipe joint 4 can slide front and back, the head of joint 2 is pre-small post-large structure, promote quick street corner toward the ladle direction, joint 2 injects in the rapid pipe joint 4, is about to both and connects, and argon gas enters ladle 1 by rapid pipe joint 4 and joint 2 it is carried out Argon; When Argon is solid,, be about to rapid pipe joint 4 and take off from joint 2 to the opposite method pulling rapid pipe joint 4 of ladle.
Because the length of handle 8 can be provided with according to operator's needs, can make the operator from connecing, get the argon pipe easily, and the operator that can not burn significantly reduce accident from the ladle larger distance.
