Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to heavy objects such as buildings (approximately 10,000 to 10,000 tons).
The present invention relates to a heavy load transfer device that moves a machine to a predetermined place as it is.

[Conventional technology]

To move a large integrated building such as a concrete building from its installation location to another desired location, dig a part of the ground below the building, such as the four corners of the building, and lower the footing rails. , Lay the roller on the receiving rail, place the iron plate on it,
A method is generally used in which a wedge-shaped sleeper is installed between an iron plate and a footing lower part to support the building, and then the entire building is gradually moved through a building pushing mechanism such as a hydraulic jack.

[Problems to be Solved by the Invention] However, in the method of moving by using the above-mentioned roller and the pushing mechanism, the stroke of the pushing hydraulic jack limits the pushing distance of one push, and therefore the jack must be replaced. Work was needed. Furthermore, the pushing operation was extremely inefficient because it was necessary to sequentially replace the moved rollers with the front.

Therefore, it is an object of the present invention to move heavy objects (1000 to 10
In the transfer device for 000ton class), it is installed at the bottom of the foundation footing of a building, etc. to support the building, etc., and it is self-propelled for a desired distance on the receiving rail without replacement work, greatly improving work efficiency. It is to increase. Furthermore, it is another object of the present invention to realize a heavy-weight transfer device that prevents slipping and enables a high-power, ultra-low-speed transfer that allows a gentle cushion-free cushion start.

[Means for solving problems]

In order to achieve the above object, in the present invention, in a trolley type heavy object transfer device for moving a heavy object on the top surface of a top plate, a hydraulic motor as a drive source and a spur gear Is fixed to the shaft end by rotating an intermediate shaft whose both ends are supported by roller bearings, a worm gear engaged with the intermediate shaft, and a worm wheel engaged with the worm gear, and engaged with the rail. A flange is attached to the surface of the receiving roller, and it consists of a plurality of shaft rods that are inserted through the left and right side plates and laterally mounted. The present invention provides a heavy load transfer device characterized in that it rolls.

Example of Invention

 An embodiment of the transfer device of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of the transfer device of the present invention. A required heavy object is placed on the top plate 1 and is configured as a dolly which can be moved by itself on the receiving rail 16 via the receiving roller-shaped shaft rod 4 provided on the lower surface. An upper cover 12 is provided above the spur gear 7.
However, side covers 14 are also attached to the sides, respectively. The top plate is made as a low-floor box-shaped member, and the parts such as the hydraulic motor 6 and the intermediate shaft 8 that are housed are lower than the top plate 1. The proper place of 1 upper surface can be made into a required support surface.

Next, FIG. 2 is a plan view of the transfer device of the present invention with the top plate and the upper cover removed. A plurality of (two in this embodiment) shaft rods 4 are horizontally mounted over the left and right side plates 2 and 3 integrally formed by fixing the upper end to one top plate 1.
At the lower outer edge of the side plate 3, a hydraulic motor 6 and an intermediate shaft 8 rotated from the hydraulic motor 6 via two spur gears 7 are horizontally supported by roller bearings 9 at both ends. It is provided in. A worm gear 10 is engaged with the intermediate shaft 8, and the worm gear 10 is engaged with a worm wheel 11 fixed to the shaft rod 4 located below. When the intermediate shaft 8 rotates, the two shaft rods 4 rotate in the same direction, but in this case, since a worm gear is used, a large reduction ratio can be obtained in one step, and it will not run if the motor is stopped. It has become.

Next, FIG. 3 is a front view of the transfer device of the present invention. Axle 4
Has a flange 15 for engaging the receiving rail on the side plate 3 side.
Is attached.

Next, FIG. 4 shows an embodiment in which the transfer device of the present invention is arranged at four corners below the foundation footing of a heavy object. First of the four corners
Digging the required position to the required depth, laying the receiving rail 16 and engaging the transfer device with the receiving rail 16 and arranging so that the corner of the building is mounted on the top surface of the top plate 1 and other transferring device. Are similarly arranged. Next, the hydraulic motor 6 of each transfer device is connected to the hydraulic pump 17 via a hose, and each transfer device is simultaneously driven to move the heavy load 18.

〔The invention's effect〕

Since the device of the present invention is of a self-propelled type, the pushing distance is not limited, and there is no need to replace rollers or the like, so that the work efficiency can be greatly increased. Furthermore, the output rotation of the hydraulic motor changes in response to changes in the flow rate pumped from the hydraulic pump, and deceleration can be easily achieved. It can be transported and stopped without shock even when stopped. Further, since all of the shaft rods are driven, there is no slippage with the receiving rail.
