SUMMERY OF THE UTILITY MODEL
The utility model aims to solve current locking device and have above-mentioned defect, the utility model provides a locking device for combining pushing off the slag cone and guide bar for pushing off the slag cone, the device have combine firm reliable degree high, the characteristics that stokehole worker working strength is low, realize that guide bar and cone combine firmly, pushing off the slag in-process guide bar off-rate is less than 0.5% target, solved the pushing off the slag cone that exists at present and combined not tight defect with the guide bar.
In order to achieve the above object, the utility model provides a locking device for combining pushing off slag cone and guiding bar for pushing off slag cone, it includes: the device comprises deformed steel bar, a guide rod, a slag blocking cone and a locking pressing sheet;
The threaded steel sleeve is arranged in the guide rod and extends out of two ends of the guide rod; the locking pressing sheet is fixed on the deformed steel bar and is not contacted with the guide rod; and inserting the guide rod into the slag blocking cone, and inserting the deformed steel bar fixed with the locking pressing sheet into the slag blocking cone at the same time to complete the combination of the guide rod and the slag blocking cone.
As one improvement of the device, the locking pressing sheet is positioned above the guide rod, and the locking pressing sheet is separated from the guide rod by at least 200 mm.
As one improvement of the device, a plurality of U-shaped openings are distributed on the outer diameter of the locking pressing sheet at equal intervals, and a closed elongated hole is formed in the inner diameter of the locking pressing sheet along the outer diameter direction.
As one improvement of the device, the solid part between the inner diameter of the locking pressing sheet and the outer diameter of the locking pressing sheet is of a hollow structure, so that when the guide rod is combined with the slag blocking cone, the guide rod and the slag blocking cone can be tightly combined and locked in a one-way mode through plastic deformation, and the guide rod is prevented from falling off from the slag blocking cone.
As one improvement of the device, the locking pressing piece is made of a steel plate with the thickness of 0.8-1.21 mm in a stamping mode.
When the cone and the guide rod are assembled on site, the guide rod is directly inserted into the cone until the cavity in the slag stopping cone is filled; due to the co-extrusion effect of the deformed steel bar and the inner cavity of the slag blocking cone, the locking gasket is tightly embedded in the four walls of the inner cavity of the slag blocking cone after plastic deformation, so that one-way locking is formed, and the guide rod is effectively prevented from falling off midway.
The utility model has the advantages that:
The device of the utility model ensures the firm combination of the slag stopping cone and the guide rod, and the falling rate of the guide rod from the slag stopping cone is only 0.1 percent in the slag stopping process; the on-site operation flow of stokehole workers is greatly simplified, the working procedure of coating refractory mortar is omitted, and the labor intensity of workers is reduced.

Detailed Description
the invention will now be further described with reference to the accompanying drawings.
as shown in fig. 1, the utility model provides a locking device for combining pushing off slag cone and guide bar for pushing off slag cone, it includes: the device comprises deformed steel bars 3, a guide rod 2, a slag blocking cone 4 and a locking pressing sheet 1;
the deformed steel bar 3 is sleeved in the guide rod 2 and extends out of two ends of the guide rod 2; the locking pressing sheet 1 is fixed on the deformed steel bar 3 and is not contacted with the guide rod 2; and inserting the guide rod 2 into the slag blocking cone 4, and simultaneously inserting the deformed steel bar 3 fixed with the locking pressing sheet 1 into the slag blocking cone 4 to complete the combination of the guide rod 2 and the slag blocking cone 4.
As one of the improvements of the above device, as shown in fig. 2, the locking blade 1 is located above the guide bar 2, and the locking blade 1 is spaced from the guide bar 2 by at least 200 mm.
As one improvement of the above device, as shown in fig. 3, a plurality of U-shaped openings are distributed on the outer diameter of the locking pressing sheet 1 at equal intervals, and the inner diameter of the locking pressing sheet 1 is provided with a closed elongated hole along the outer diameter direction.
as one improvement of the device, the solid part between the inner diameter of the locking pressing sheet 1 and the outer diameter of the locking pressing sheet 1 is of a hollow structure, so that when the guide rod is combined with the slag blocking cone, the guide rod and the slag blocking cone can be tightly combined and locked in a one-way mode through plastic deformation, and the guide rod is prevented from falling off from the slag blocking cone. Wherein, the inner diameter of the locking pressing sheet 1 is 9-13 mm, and the outer diameter is 41-44 mm.
As one improvement of the device, the locking pressing piece 1 is made of a steel plate with the thickness of 0.8-1.2 mm in a stamping mode.
