Description

  The present invention is a weight used for transferring and transferring a heavy object having a weight of about 20 to 50 tons for new installation or replacement, such as a transformer installed in a substation of a power company or a manufacturing apparatus of a factory. The present invention relates to an object moving device and a heavy object transfer device.

  For example, when a transformer is newly installed or replaced at an outdoor substation, a large crane that handles heavy loads due to the presence of existing transformers and wiring, and the ground is not necessarily flat. Since most vehicles cannot be used on site, the current situation is to move heavy objects using a roller (log), which is a primitive method.

In the work using rollers, a large number of rollers are arranged at appropriate intervals in the moving direction of the heavy object, and the rear roller is carried forward in the moving direction according to the progress of the heavy object pulled by the work vehicle such as a wheel loader. In order to repeat the work, the rollers that have passed through the heavy objects are transported to the front again.

  In addition, it is sufficient if a heavy crane can be used when transporting heavy objects with a transport vehicle such as a trailer vehicle and dropping it to the site. It is a fact that long steel plates are placed between the loading platform and the ground and pulled down by a work vehicle, and the work vehicle is inefficient and dangerous. Some sites cannot be used for towing, and there is a problem that it takes a lot of time to drop heavy objects to the site.

Not found.

However, the work using rollers requires a lot of workers because it uses a large number of rollers, and requires a long work time. It is necessary to level the ground in advance on slopes and cannot be used on upslopes. is there. In addition, there are many drawbacks such as a lot of work time for changing the direction, and the danger that the worker may pinch the hand between the roller and the ground in order to quickly and sequentially arrange the rollers in the transfer direction. . In fact, no working method or machine has been proposed to replace the use of rollers.

In addition, the work of dropping heavy objects from the transport vehicle to the site has the disadvantages of poor work efficiency and danger, and there are some sites where the work vehicle cannot be used for towing. There is a problem that it takes time.

  The present invention has been made in view of the above-mentioned drawbacks of the prior art, and by mechanizing the movement and transfer of heavy objects, it is possible to ensure safety during work and to reduce work time and workers. Therefore, it is an object of the present invention to provide a heavy load moving device and a heavy load transfer device that can greatly reduce the operation cost and can move a heavy load as long as it is a gently upwardly inclined surface.

  Means for constructing the present invention according to claim 1 for solving the above-described problem includes a mounting table on which a heavy object is placed on an upper surface, and four moving mechanisms provided on the mounting table so as to be separated in four directions.

A moving rail plate in which a plurality of load support plates are fixed at predetermined intervals in the longitudinal direction, a mounting slide plate which is slidably disposed on the moving rail plate and carries a heavy load, and a push support And a heavy load pushing means for moving the heavy load by sequentially engaging the load bearing members of the rail plate for movement and extending the push contact body in contact with the weight portion. Consists of.

  The load support plate may be provided with a sliding contact material exposed on the upper surface.

Since the present invention is configured as described above, the following effects are obtained.

  The heavy article moving device 1 includes an elevating hydraulic cylinder 8 and a moving hydraulic cylinder 12 as operating means, and the heavy article transferring device 21 includes a pushing hydraulic cylinder 26. The basic configuration and operation thereof are as follows. Since it is the same as existing hydraulic equipment such as lifting lifts and hydraulic cranes, the details of these configurations and operations are omitted.

The heavy article transfer device 21 according to the present embodiment has the above-described configuration, and its operation is linked to the heavy article transfer device 1 and will be described together.
When the heavy object W mounted and transported on the carrier U of the transport vehicle T is transferred to the heavy article moving device 1, for example, a square steel material or an H-shaped steel material so that the surfaces of the carrier U and the carrier 2 are substantially the same. After placing and adjusting the interposing material S such as the transfer rail plates 22 and 22 and placing them between the loading platform U and the mounting table 2, the mounting is carried on each moving rail plate 22.

In this way, the heavy object W placed on the mounting slide plate 25 moves forward with the interval width of the load support body 24 as one distance. At this time, since the sliding member 24C is exposed on the upper surface 24A of the load support plate 24 to enhance the slidability, the mounting slide plate 25 on which the heavy object W is placed can smoothly advance. By repeatedly performing the above-described operation, the heavy object W can be transferred from the loading platform U to the mounting platform 2 safely and in less than half the conventional work time.

When the operation of transferring the heavy object W to the mounting table 2 is completed, the operation of moving the heavy object W to the installation location by the heavy object moving device 1 will be described with reference to FIGS.

Next, the lifting hydraulic cylinder 8 is extended to bring the movable tread 11 into contact with the ground G, and the mounting base 2 is raised in the direction indicated by the arrow (B). In this state, the mounting hydraulic cylinder 12 is moved forward by extending the moving hydraulic cylinder 12 and moving the main leg 9 forward in the direction of arrow E with respect to the movable tread 11 (C). Thereafter, the lifting hydraulic cylinder 8 is retracted to ground the mounting base 2 and the movable tread 11 is lifted from the ground G (D), and then the moving hydraulic cylinder 12 is extended to the main leg 9. Then, the movable tread 11 is advanced in the direction indicated by the arrow E to achieve the state (A).

In this way, by repeatedly performing the operations A to D, the heavy object W can be moved to a predetermined location. And when changing the advancing direction in the middle of the movement, the main leg 9 and the movable tread 11 are rotated with respect to the support base 7 for each of the moving mechanisms 6 while rotating the necessary angles in the two directions to change the directions. The above operations A to D are performed. The traveling operation and the direction changing operation are performed by rotating the main leg 9 and the movable tread 11 several times and moving forward while considering various conditions such as the ground condition of the work place and the movable area. Can do.

  In this way, the work of installing the heavy object W carried by the transport vehicle at a predetermined place is transferred from the transport vehicle to the mounting base 2 of the heavy load transport apparatus 1 using the heavy load transfer device 21, Although the contents are conveyed by the mobile device 1, all of these operations are mechanized so that they can be performed safely and efficiently, and the number of workers can be reduced as much as possible, thereby reducing labor costs. In addition, since the heavy goods moving device 1 and the heavy goods transfer device 21 are configured to be operated by a hydraulic cylinder, the heavy goods W can be moved even on an upward inclined surface of about 5%, which was impossible with a roller. In addition, workability is excellent because it is not necessary to level the slope.

Moreover, although the hydraulic cylinder was used in the embodiment as the moving mechanism 6 and the moving drive means 12 of the heavy article moving device 1 and the heavy article pushing means of the heavy article transfer device 21, an electric motor is used. Is also good.
