Labeled as: the hot blast bustle pipe comprises a hot blast bustle pipe 1, a horse ear flange 2, a flange plate 21, an assembling device 3, a flange plate 31, a bolt hole 311, a supporting base 32, a supporting rod 33 and an assembling platform 4.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The hot blast bustle pipe horse ear flange assembly device shown in fig. 1, fig. 2, fig. 3 and fig. 4 comprises a supporting base 32, wherein a supporting rod 33 is arranged on the supporting base 32, a flange plate 31 is fixedly arranged at the top of the supporting rod 33, the shape of the flange plate 31 is matched with the flange plate 21 of the supported horse ear flange 2, and a detachable connecting structure is arranged between the flange plate 31 and the flange plate 21.
Because blast furnace when overhaul at every turn, all need to change bustle pipe 1 and horse ear flange 2, and in actual operation, the assembly of horse ear flange 2 is very complicated, and the degree of difficulty is great, need consume more manual work and the precision is difficult to guarantee. Meanwhile, a horse ear flange 2 of the blast furnace air supply device is attached to the lower part of the bustle pipe 1, a flange plate 21 at the lower opening of the horse ear flange 2 is inclined by a certain angle, and the center of the horse ear flange 2 is away from the center of the bustle pipe 1, so that the assembly difficulty is high. The utility model discloses to this technological problem, ingenious design hot-blast surrounding pipe horse ear flange assembly device. During actual operation, at first set up assembly device 3 on assembly platform 4, put down the horse ear flange 2 of waiting to install from hot-blast bustle pipe 1 afterwards to lean on behind the flange plate 31 of this assembly device 3 and carry out the fixed of position, can realize when later stage welding with stable and high-efficient. Preferably, the support bar 33 is an angle steel, so as to ensure the actual support requirement.
In order to match the actual horse-ear flange 2 and the actual assembly platform 4 position, the following options are selected: the supporting base 32 is arranged horizontally, the flange plate 31 is arranged obliquely to the horizontal plane, and the inclination angle of the flange plate 31 is consistent with the angle of the flange plate 21 oblique to the horizontal plane. In actual operation, the supporting base 32 is horizontally disposed and is consistent with the horizontal assembling platform 4, and then, the inclination angle of the flange plate 31 is consistent with the inclination angle of the flange plate 21 to the horizontal plane, so as to ensure that the requirement of the inclination angle of the horse-ear flange 2 is met.
In order to facilitate the fixing and detaching between the flange plate 31 and the flange plate 21, it is preferable that: the flange plate 31 is provided with bolt holes 311, the flange plate 21 is provided with mounting holes corresponding to the bolt holes 311, wherein the flange plate 31 and the flange plate 21 are connected through fixing bolts arranged in the bolt holes 311 and the mounting holes of the flange plate 21. Because need satisfy between flange plate 31 and the ring flange 21 for dismantling connection structure, consequently, can select foretell scheme, when needs are fixed between flange plate 31 and the ring flange 21, realize being connected through fixing bolt, when the welding finishes needs the partition, then unscrew fixing bolt can. Generally, for the uniformity of the force and the stability of the support, it is preferable that the bolt holes 311 are uniformly distributed around the geometric center of the flange plate 31.
