Use the utility model discloses the time, earlier with saddle shaped support welding on rotary kiln barrel surface, then hoist and mount bull gear to installation position, through adjustment axial adjusting bolt and radial adjusting bolt, after the alignment bull gear and the axiality of rotary kiln barrel, install the bull gear on the rotary kiln barrel, rethread cutting mode takes off.
Description
Technical Field
The utility model relates to a specialized tool is changed to rotary kiln bull gear for alignment bull gear and the axiality of rotary kiln barrel when the bull gear is changed or the turn-over installation.
Background
The large gear ring of the rotary kiln consists of two halves, and is generally hoisted and installed by large hoisting equipment due to large volume and is connected into a whole by a butt screw. The large gear ring is the most key part of a rotary kiln transmission device, and the installation quality of the large gear ring directly influences the transmission of a rotary kiln and influences the stable operation of a kiln system. Therefore, when the large gear ring is replaced or turned over for installation, the alignment and adjustment of the coaxiality of the large gear ring and the rotary kiln cylinder are needed, the precision requirement is difficult to achieve through manual operation, and the construction time is long. CN215113870U discloses a supporting structure for mounting a large gear ring of a rotary kiln, which is an auxiliary device for mounting a large gear ring of a rotary kiln, and aims to perform multi-freedom controllable displacement adjustment on the large gear ring of the rotary kiln, so that the large gear ring of the rotary kiln can be quickly and accurately aligned and mounted with the axis of a kiln cylinder, thereby improving the mounting efficiency of the large gear ring of the rotary kiln. However, the alignment adjustment of the large gear ring assembled by the two half gear ring groups outside the rotary kiln cylinder body is carried out by the equipment, the whole equipment is huge, the structure is complex, how to move the large gear ring aligned and adjusted to the rotary kiln cylinder body in a document is not described, and if the hoisting equipment is still adopted for hoisting and mounting, the position of the large gear ring cannot be ensured not to be deviated, and the problem of coaxiality of the large gear ring and the rotary kiln cylinder body cannot be solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem to a specialized tool is changed to rotary kiln bull gear that construction convenience, construction precision are high is provided.
The utility model provides a problem, the technical scheme who adopts is:
a special tool for replacing a large gear ring of a rotary kiln is characterized in that a main body of the tool is a saddle-shaped support arranged between a rotary kiln cylinder body and the large gear ring, two limiting baffles which are oppositely arranged are arranged on the upper surface of the saddle-shaped support, the distance between the two limiting baffles is larger than the thickness of the large gear ring, axial adjusting bolts for adjusting the axial displacement of the large gear ring are respectively arranged on the two limiting baffles, and the two axial adjusting bolts are symmetrically and oppositely arranged; and a radial adjusting bolt for adjusting the radial displacement of the large gear ring is arranged on the saddle-shaped support corresponding to the central position of the two limit baffles.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
when the bull gear installation, earlier with the welding of shape of a saddle support on rotary kiln barrel surface, then hoist and mount bull gear to installation position, through adjustment axial adjusting bolt and radial adjusting bolt, after the alignment bull gear and the axiality of rotary kiln barrel, install the bull gear on the rotary kiln barrel, the rethread cutting mode will the utility model discloses take off.
Secondly, the tool assembly can be manufactured on site by using materials on site, the manufacturing time is short, and further the construction period is short.
Preferably, the present invention further provides:
the lower part of the saddle-shaped support is vertically jointed and welded with the outer edge surface of the rotary kiln cylinder.

The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1 to 7, a special tool for replacing a large gear ring of a rotary kiln is characterized in that a main body of the tool is a saddle-shaped support 1 arranged between a rotary kiln cylinder 6 and a large gear ring 5, two opposite limiting baffles 2 are arranged on the upper surface of the saddle-shaped support 1, the distance between the two limiting baffles 2 is greater than the thickness of the large gear ring 5, axial adjusting bolts 3 for adjusting the axial displacement of the large gear ring 5 are respectively arranged on the two limiting baffles 2, and the two axial adjusting bolts 3 are symmetrically and oppositely arranged; the saddle-shaped support 1 is provided with a radial adjusting bolt 4 for adjusting the radial displacement of the large gear ring 5 relative to the central position of the two limit baffles 2.
When the special tool for replacing the large gear ring of the rotary kiln is used for installing the large gear ring 5, the large gear ring 5 is preassembled, the center of the gear ring is found, six equal parts are performed along the circumference, six special tools for replacing the large gear ring of the rotary kiln are correspondingly configured, and the six equal parts of the tools are respectively welded on the outer circle of the cylinder body of the rotary kiln 6.
Hoisting the large gear ring 5, adjusting the axial adjusting bolt 3 and the radial adjusting bolt 4, aligning the coaxiality of the large gear ring 5 and the rotary kiln 6 barrel, and installing the large gear ring 5 on the rotary kiln 6 barrel. After the large gear ring 5 is installed, the tool body is detached through a cutting mode. Adopt this embodiment rotary kiln bull gear change specialized tool carry out bull gear 5 installation, improved the installation accuracy of bull gear 5, and simple to operate, labour saving and time saving, the instrument subassembly can draw materials the on-the-spot preparation of drawing materials, and the preparation time is short, and then makes construction cycle short.
