Background

The refining furnace is a smelting device in the hot working industry, is used for carrying out final deoxidation and alloying processes on molten steel in ferrous metallurgy, and is mainly produced with an RH refining furnace and an LF refining furnace, wherein LF is a ladle refining furnace and is mainly used for desulfurization and heating of the molten steel.

In the prior art, the operation shed is generally positioned outside the working platform so as to be close to a steel ladle and facilitate argon blowing operation. But in the daily production process, when the operative employee connects the argon blowing pipe to the ladle, the driving removes the ladle to operation canopy position, because the space is less, the driving removes the in-process and often bumps into the argon blowing operation canopy of protrusion in the platform outside, cause operation canopy steel structure to desolder and warp, make the operative employee can't continue to operate in the canopy, the protection of operation canopy has not been had, operative employee's safety can't be ensured, seriously influence safety in production, in addition the operation canopy is located the eminence, it is very difficult to maintain, waste a large amount of manpower financial resources.

SUMMERY OF THE UTILITY MODEL

The main object of the utility model is to provide a telescopic refining furnace argon blowing operation canopy can effectively solve the problem in the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a telescopic argon blowing operation shed for a refining furnace comprises a base sliding groove arranged on the ground, wherein a base is connected in the base sliding groove in a sliding manner, an operation shed is fixed at one end of the base, a pedal is fixed in the middle of the base, the pedal is tightly attached to the operation shed, the inner bottom surface of the operation shed is flush with the top surface of the pedal, and a sliding driving mechanism is connected to the pedal; in an initial state, the operation shed is collected inside the sliding groove of the base.

Furthermore, the base middle part is connected with the pulley with rotating on the both sides wall of the other end, interior spout has been seted up on the both sides wall of base spout, the pulley block just rotates in the spout including.

Furthermore, the sliding driving mechanism comprises a plurality of horizontal cylinders fixed on the bottom surface of the base sliding groove, telescopic rods of the horizontal cylinders are parallel to the side walls of the base sliding groove, and the tail ends of the telescopic rods are fixed on the side walls of the pedal.

Furthermore, one side surface of the operation shed is an operation surface, and an operation opening is opened at the upper part of the operation surface.

Preferably, the horizontal cylinder is two parallel to each other.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses in, change argon blowing operation canopy into retractable, during the use, when the driving a vehicle and the ladle has not been shut down steadily, the operation canopy is received in work platform inboard, and after the driving a vehicle and the ladle is shut down steadily, the operation canopy stretches to the outside so that the workman carries out the argon blowing operation from work platform promptly, the risk that the telescopic operation canopy has effectively avoidd and has been run into bad by the driving a vehicle, successfully reduce the 24 damage rate of operation canopy/year to 2 times/year;

2. the utility model discloses in, the base that is arranged in bearing is from two aspects protection operation canopy operating personnel's safety, is the pulley block through both sides in the inner chute of base spout both sides on the one hand for the base can stably be removed and can not tumble, and on the other hand is realized consolidating the holistic secondary of base through connecting the horizontal cylinder telescopic link on the footboard, has further strengthened the stability of base.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in figures 1-4, a telescopic argon blowing operation shed for a refining furnace comprises a base sliding groove 1 arranged on the ground, a base 2 is connected in the base sliding groove 1 in a sliding manner, pulleys 5 are rotatably connected on the two side walls of the middle part and the other end of the base 2, inner sliding grooves are arranged on the two side walls of the base sliding groove 1, and the pulleys 5 are clamped and rotate in the inner sliding grooves. Base 2 one end is fixed with operation canopy 3, and the middle part is fixed with footboard 4, and operation canopy 3 is hugged closely to footboard 4, bottom surface and 4 top surfaces parallel and level of footboard in the operation canopy 3, and operation canopy 3 has a side to be operation face 7, and 7 upper portions of operation face are opened there is operation mouth 8, is connected with the slip actuating mechanism on the footboard 4. The sliding driving mechanism comprises two horizontal cylinders 6 fixed on the bottom surface of the base sliding groove 1, telescopic rods of the horizontal cylinders 6 are parallel to the side wall of the base sliding groove 1, and the tail ends of the telescopic rods are fixed on the side wall of the pedal 4.
