Description

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

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. When installing a boiler like this, conventionally there are many jacks at the bottom of the boiler! [The mounting position was adjusted manually by numerous workers.]

The present invention eliminates the adjustment that conventionally required many people and a long time, and the suspension support 1d! It is an object of the present invention to provide a J'fl lifting device that can simplify the final lifting for butting and mounting.

The invention will now be described in detail with reference to the figures. A pair of frames 2.degree. 2 are installed on beams A-H 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, a pair of opposing jacks 7.
Kites 8 and 8 are vertically provided on both sides of the jacks 7, and a lifting platform 6 is placed on the jacks 7 and 7.

N4f at the bottom of the lifting platform 6! A JI+II cylinder 9 is provided, which is slidably fitted into a guide 8 on the pedestal 2 to allow the lifting table 6 to move up and down vertically.

Four guide columns 10 are erected on the pedestal 2 at the outside of the four corners of the elevating table 6. Each guide column 10 guides the boiler B when it is lowered onto the lifting platform 6.

A pair of guide columns 10 on sides facing the other pedestal 2.
10, there are ribs b, b on both sides of the boiler B so as to be perpendicular to the rail 1 and facing the other frame 2, respectively.
A first volatile pressure regulator 1i 4'& il is provided which can press . In the illustrated embodiment, the first pressure adjustment mechanism 11 consists of screw punches 14 with handles 13 screwed into screw holes in a bracket 12 fixed to the guide post 10, respectively. The tip of the screw punch 14 can press the ribs b, b, which are fixed to both sides of the boiler B in the longitudinal direction, so as to project from both sides in the longitudinal direction of the boiler B. The guide column 10.10 on the opposite side is provided with second pressure adjustment mechanisms 15, 15 that can press both sides of the boiler B so as to face each other in the extending direction of the rail 1, respectively.

In the illustrated actual JKa example, this pressing mechanism 15 is a handle 1 screwed into a screw hole of a bracket 16 of a guide column 10.
Consists of screw pestle 18 with 7 attachments. The tip of the screw punch 18 can contact and press both side surfaces of the boiler B in the short direction.

In the illustrated embodiment, other boiler settings f1° (i position I
? Wheels 4 are provided on both sides of the pedestal 2 for convenience in transporting the device to the base 2. The vehicle width 4 is provided on a bracket 5 on the side surface of the pedestal 2 so that its vertical mounting position can be adjusted using bolts and nuts. This wheel 4 is connected to the beam A when moving the frame.
, A can be transferred on the temporary rail 1. The wheels 4 are mounted at station X, where the mount 2 is placed at a predetermined position R
Loosen the nuts, move the mounting position relatively upward, and
is lowered onto beams A and A. Further, at the bottom of the pedestal 2, as shown in FIG. 5, there is a clamp fitting 19 for fixing the pedestal 2 to the beam A.
? It is said to be removable.

Next, the action will be explained. Beam A directly below the boiler installation position 1.
, place the frames 2 and 2 facing each other on A, and fix the frame 2 to A by attaching the clamp fitting 19 to the bottom of the frame 2. Boiler B was then lifted onto the lifting platform 6 by a crane.
and lowered it until boiler B entered between the guide pillars 10. At this time, the side surface of the boiler B and its ribs B hit against the side surface of each guide column 10 and are directed to an appropriate lowered position. Boiler B is still suspended by a crane, and its IrG section extends above lifting platform 6. In this state, each screw punch 14, 18
1 of boiler B by operating the handles 13 and 17 appropriately.
Press 11+11i or its rib b to move boiler B to 11 and align the position +4 exactly with the installation position 1 foundation. Then, lower the boiler B onto the lifting platform 6, and then operate the jack 7 to move the boiler B together with the lifting platform 6 to 4111.
Raise it up and install it against the suspension support position. The elevating table 6 is vertically guided in elevating and lowering by a guide 8 and a sliding tube 9. Incidentally, it is preferable that each of the jacks 7.7 is marked with a scale, and the scales are used as a guide to operate the jacks evenly. When the installation ff and f of boiler B are completed, the jack 7 is lowered and the rack 82 is moved to another boiler installation F'U% location. At this time, a rail 1 is temporarily installed, and the vehicle width 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 1α of boiler B etc.
A pair of mounts 2, 2 fixed oppositely to each other at lower positions on both sides in the longitudinal direction of a box-shaped heavy object, a plurality of jacks 7.7 erected vertically on the mount 2, and a plurality of jacks 7.7 on the mount 2. A lifting platform 6 is provided with a number of guides 8 vertically erected in the same way, 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 placed on the outside of the four corners to guide the descent of a rectangular parallelepiped-shaped heavy object placed vertically on the pedestal 2, and a pair of opposing guide columns 10.1.
A pair of ribs b each provided on 0 and fixed so as to protrude outward from both sides of the parallelepiped heavy object in the short direction.
, b can be suppressed in the longitudinal direction of the rectangular parallelepiped 1d/large object? 1
The pressure adjustment mechanism 11.11 of 41 and the other pair of opposing guide columns 10.10 are respectively provided, and the rectangular parallelepiped-shaped t-shaped
・Both sides of one object in the short direction can be pressed 1111 times in opposing directions, respectively #+8 W; Pressure adjustment 1 of 2
