A large-diameter superheavy trim horizontal mounting rail apparatus according to an embodiment of the present invention will be described with reference to fig. 1 to 2 of the accompanying drawings, including: a rail, a trolley 4, an internal part saddle 5 and a driving mechanism.

As shown in figure 1, the trolley 4 is arranged on the track and can move along the track, the internal part saddle 5 is arranged on the trolley 4, and the trolley 4 is also provided with a driving mechanism which is connected with the internal part saddle 5 to drive the internal part saddle 5 to lift.

Orbital structural style has a lot, so in this embodiment, as shown in fig. 1, the track includes channel-section steel track 1 and track support 2, and channel-section steel track 1 is two, two channel-section steel track 1 parallel arrangement, and the bottom of dolly 4 is equipped with two gyro wheels, and two gyro wheels support respectively on two channel-section steel track 1, and track support 2 locates between two channel-section steel track 1, and track support 2 can dismantle with channel-section steel track 1 and link to each other, and for example track support 2 links to each other with channel-section steel track 1 accessible bolt and nut, the dismouting of being convenient for. Wherein, the lower surface of track support 2 is the downward convex arcwall face, this is because the casing of pressure vessel is usually curved, makes the lower surface of track support 2 the arc, can better laminate with the casing.

In this embodiment, as shown in fig. 2, the upper surface of the saddle is a downward-recessed arc-shaped surface, so that a workpiece to be mounted is supported conveniently, the downward-recessed arc-shaped surface can play a certain limiting role, and the workpiece is not easy to separate from the saddle.

The driving mechanisms in the embodiment are hydraulic jacks 6, two jacks 6 are arranged and distributed on two sides of the saddle, and the saddle can be driven to lift when the jacks 6 on the two sides work simultaneously. Of course, the driving mechanism may have another structure, and is not limited herein.

The working process of the device is as follows: firstly, the channel steel track 1 and the track support 2 are lifted into equipment and pre-assembled, then the channel steel track 1 and the track support 2 are connected through the connecting bolt 3, the connecting nut and the washer, and the connecting bolt 3 is screwed down.

Then the internal saddle 5, the jack 6 and the trolley 4 are placed on the track for assembly. The running state of the trolley 4 is checked before use, the defects that the trolley 4 runs due to the fact that no blocking groove exists between each section of channel steel track 1 and the like are guaranteed, after all problems are checked to be qualified, the trolley in a factory is used as a power installation internal part, after the internal part runs into the equipment, jacks 6 on two sides of the internal part saddle 5 are adjusted to lift the internal part saddle 5, and therefore the coaxiality between the internal part and the main shell of the equipment can be adjusted. After the coaxiality of the equipment is adjusted, circular seams between two ports of the internal part and the equipment shell are welded and fixed, after the fixation is completed, the internal part saddle 5, the supporting jack 6 and the trolley 4 are taken out, the connecting bolt 3, the connecting nut and the gasket are disassembled, the channel steel track 1 and the track support 2 are taken out in sections, the horizontal installation of the internal part is completed, and meanwhile, the track tool can be repeatedly used.

In conclusion, the device can realize horizontal installation of the large-diameter overweight internal part by means of the channel steel track 1 tool and through the matching among the track, the trolley 4, the jack 6 and the internal part saddle 5, the internal part is smooth and labor-saving and feasible in the installation process, the surface of the internal part is protected from being scratched, the height of the internal part can be finely adjusted after the internal part is installed in place, and the adjustment of the coaxiality among the internal parts at all layers is realized.

While embodiments of the utility model have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the utility model, the scope of which is defined by the claims and their equivalents.
