Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for installing rectangular heavy objects such as large boilers and related equipment in thermal power plants etc. while adjusting the installation position. This invention relates to a device for pushing up a rectangular parallelepiped-shaped heavy object.

For example, a boiler in a thermal power plant or the like is suspended with a space between it and the floor in order to release the elongation caused by thermal expansion downward. In the installation work of such a boiler, conventionally, a large number of jacks are installed at the bottom of the boiler, and the mounting positions are manually adjusted by a large number of workers.

The present invention simplifies the position adjustment during the installation work of rectangular parallelepiped-shaped large heavy equipment such as boilers, which conventionally required many people and a long time, and the final push-up to align and install it to the hanging support position. The purpose of the present invention is to provide a push-up device that can do the following.

Embodiments of the invention will be described below with reference to the figures. A pair of frames 2, 2 are installed on the beam A below the boiler installation position. A pair of frames 2 work together to support both sides of the boiler B in the longitudinal direction.

The elevating table 6 is provided on the pedestal 2 so as to be movable up and down. That is, one pair of opposing jacks 7, 7 is provided at the center of both sides of the top of the pedestal 2, and these jacks 7
Guides 8, 8 are vertically provided on both sides of the shaft, and a lifting platform 6 is placed on the jacks 7, 7.

A sliding tube 9 is provided at the lower part of the lifting table 6, and this sliding tube 9 is slidably fitted into a guide 8 on the pedestal 2 to guide the vertical elevation of the lifting table 6.

Four guide columns 10 are erected on the pedestal 2 at positions outside the four corners of the lifting platform 6. Each guide pillar 1
0 guides the boiler B when lowering it onto the lifting platform 6.

The ribs b, b on both sides of the boiler B can be pressed on the pair of guide columns 10, 10 on the sides facing the other pedestal 2, respectively, in a direction orthogonal to the rail 1, so as to face the other pedestal 2, respectively. A first pressure adjustment mechanism 11 is provided. In the illustrated embodiment, the first pressure adjustment mechanism 11 consists of screw rods 14 with handles 13 screwed into screw holes in a bracket 12 fixed to the guide post 10, respectively. and,
The tip of the screw rod 14 can press the ribs b, b, which are fixed to extend on both sides of the boiler B in the longitudinal direction, and press the ribs b in the longitudinal direction of the boiler B.
The guide columns 10, 10 on the opposite side are provided with second pressure adjustment mechanisms 15, 15 that can press both side surfaces of the boiler B so as to face each other in the extending direction of the rail 1, respectively. In the illustrated embodiment, this pressing mechanism 15 consists of a threaded rod 18 with a handle 17 screwed into a threaded hole in a bracket 16 of the guide post 10.
The tip of the screw rod 18 can come into contact with both side surfaces of the boiler B in the short direction and press them.

In the illustrated embodiment, wheels 4 are provided on both sides of the pedestal 2 for convenience in transporting the device to another boiler installation location. The wheel 4 is mounted on a bracket 5 on the side surface of the pedestal 2 using bolts and nuts so that its vertical mounting position can be adjusted. This wheel 4
can roll on a rail 1 temporarily installed between the beams A and A when the frame is moved. Then, with the pedestal 2 placed at a predetermined position, the wheel 4 is moved relatively upward by loosening the nut, and the pedestal 2 is lowered onto the beams A, A. Further, at the bottom of the pedestal 2, as shown in FIG. 5, a clamp fitting 19 for fixing the pedestal 2 to the beam A is detachably attached using bolts and nuts.

Next, the action will be explained. Place the frames 2 and 2 facing each other on the beams A and A directly below the boiler installation position, and attach the clamp fitting 19 to the bottom of the frame 2.
Fix it to beam A. Then, the boiler B lifted by a crane is brought onto the lifting platform 6 and lowered until the boiler B enters between the guide columns 10. At this time, the side surface of the boiler B and its ribs b come into contact with the side surface of each guide column 10 and are guided to an appropriate lowered position. Boiler B is still suspended by a crane and its bottom is floating on the lifting platform 6. In this state, each screw 14, 1
By appropriately operating the handles 13 and 17 of 8, the boiler B is moved by pushing the side surface of the boiler B or its rib b, and its position is precisely aligned with the installation position. Then, lower the boiler B onto the lifting platform 6,
Next, operate the jack 7 to push up the boiler B together with the lifting platform 6, and attach it to the suspension support position.
The elevating table 6 is vertically guided in elevating and lowering by a guide 8 and a sliding tube 9. Note that it is desirable that the jacks 7, 7 be provided with scales, respectively, and that they be operated evenly using the scales as a guide. When the installation of boiler B is completed, the jack 7 is lowered and the mount 2 is moved to another boiler installation location. At this time, the rail 1 can be temporarily installed and the wheels 4 can be rolled along it.

Note that the present invention is not limited to the illustrated embodiment. Applications are not limited to boosting boilers.
In addition, it can be used, for example, to push up rectangular parallelepiped-shaped heavy objects such as boiler-related equipment.

As explained above, the present invention provides boiler B
A pair of frames 2, 2 are fixed oppositely to each other at lower positions on both sides in the longitudinal direction of a rectangular parallelepiped-shaped heavy object, and a plurality of jacks 7, 7 are vertically installed on the frames 2.
, a plurality of guides 8 similarly vertically erected on the pedestal 2, and a lifting platform 6 equipped with a sliding tube 9 placed on a jack 7 and fitted on the lower surface with the guides 8 so as to be vertically slidable; Four guide columns 10 are located on the outside of the four corners of the lifting platform 6 and vertically erected on the platform 2 to guide the descent of a rectangular parallelepiped-shaped heavy object, and a pair of opposing guide columns 10, 10 are provided respectively. a first pressure adjustment mechanism 11 capable of pressing a pair of ribs b, b provided and fixed so as to protrude outward from both sides of the rectangular parallelepiped-shaped heavy object in the longitudinal direction; 11
and second pressure adjustment mechanisms 15, 15 which are provided on the other pair of opposing guide columns 10, 10, respectively, and are capable of pressing both sides of the rectangular parallelepiped heavy object in the short direction, respectively, in opposite directions. With this configuration, it is possible to obtain a device for pushing up a rectangular parallelepiped heavy object that can easily perform fine adjustment of the position when installing the rectangular parallelepiped heavy object and accurately push it up to the mounting position.
