Abstract

A self-stepping transporter is provided to increase efficiency by removing accompanying job generated during the transfer and to guarantee safety. A self-stepping transporter includes an outer box(1) to support load of a heavy object when a hydraulic jack is not operated, a vertically reciprocating hydraulic jack(2) to lift the heavy object, a horizontally reciprocating hydraulic jack(3) to transfer the heavy object, sensors(4,5) to check behaviors of the horizontally and vertically reciprocating hydraulic jacks, a sliding plate(7) attached to the upper side of the vertically reciprocating hydraulic jack to smoothly transfer the heavy object, a sliding pad attached to the upper end of the outer box, and a control system to control the movement of the hydraulic jacks. When the vertically reciprocating hydraulic jack is lifted, the outer box is separated from the ground and the heavy object is supported by only the vertically reciprocating jack. Then, when the horizontally reciprocating hydraulic jack is advanced, the heavy object moves by a maximum stroke of the horizontally reciprocating hydraulic jack.

The present invention relates to a heavy weight moving device that enables simple and quick installation even in a narrow space when carrying a manufactured heavy weight, and ensures its operation and convenience and safety at the same time.

 In general, heavy weights are constructed directly at the design position, but when replacing the top plate of the bridge in which the vehicle is running or importing the heavy weights manufactured at the factory, the manufacturing position and the construction position of the heavy weights are different. In order to move the manufactured heavy weight to a predetermined position, a crane can be installed and moved directly, or a temporary facility such as a cabin is installed on the side of a design location, and then a structure is manufactured thereon to move onto a rail installed on the bench. The cart was used for transportation. However, when moving heavy objects by crane, not only the construction cost is high, but also the possibility of cable breakage or damage to the structure due to the action of the physical force between the structure to be moved and the cable that connects the structure, and the possibility of the crane to fall. exist. In addition, this method can not be used in a small work space has a problem of a large space constraint.

 In addition, most of the heavy duty moving trolleys installed with rails on the gage are composed of wheels at the bottom, so if the wheels moving the trolley are eccentric for some reason, the trolleys may be derailed and the heavy weight falling accident may occur. There is a disadvantage that can not guarantee safety, and as the truck proceeds, it is cumbersome to install the reaction wall continuously, which requires a lot of manpower and time, and thus the construction is not excellent.

The purpose is to ensure the convenience and safety of the installation and operation of the mobile device at the same time to move the manufactured weight to a predetermined position.

The present invention for solving the problems of the existing method is a vertical double-acting jack for the lifting work and load support during the preparation for moving the heavy load and a horizontal double-acting jack for horizontal movement of the heavy load in the raised state, vertical, horizontal after one run Outer box part for supporting heavy loads when returning double acting jacks, a simultaneous control system for consistently controlling the behavior of hydraulic jacks when four or more devices are used at the same time, and associated horizontal and vertical sensors.

Hereinafter, the present invention will be described in more detail. 1 is a side perspective view of the present invention. As shown in FIG. 1, the present invention provides an outer box part 1 for supporting a load of a heavy object when the hydraulic jack is not operating, a vertical double acting hydraulic jack 2 for lifting a heavy object, and a heavy object. Horizontal double acting hydraulic jack (3) responsible for the movement of the sensor, sensors (4), (5) to check the horizontal and vertical movement amount and the behavior of the hydraulic jack, vertical double acting hydraulic jack (3) to smoothly move the heavy object And a sliding pad (8) attached to the sliding plate (7) attached to the upper side of the outer box portion, and a control system (FIG. 3) for controlling the movement amount and the integrated movement of the hydraulic jack. If one unit of the same structure is supported at four or more points where the load of the heavy load is equally loaded, for example, on the part of the slab, etc., the vertical double acting hydraulic jack 3 is elevated. The outer box part (1) is separated from the ground And the heavy material is supported by the vertical hydraulic jack 2 only at each point. Then, when the horizontal hydraulic jack 3 is pushed out, the weight moves together by the maximum stroke of the horizontal hydraulic jack 3. After progressing by the stroke of the horizontal hydraulic jack 3, the vertical hydraulic jack 2, which is currently supporting the heavy weight, is retracted again to support each point of the heavy weight with the outer box portion 1 as the first time and expand ( The horizontal hydraulic jack 3, which has been advanced), is retracted to return to its original position, and then the weight is moved by repeating the above-described manner. In addition, if the vertical and horizontal movement of the vertical hydraulic jack (2) and the horizontal hydraulic jack (3) does not have the same size at four or more positions at the same time, the moving direction may be deviated or the support point may be unbalanced to prevent smooth operation and to cause safety accidents. Since there is a possibility of causing it, a hydraulic jack control system (Fig. 3) was installed to constantly control the behavior of the jacks installed at each location.

Unlike conventional heavy duty trucks, it is easy to install by reducing its external size, minimizing manpower and equipment required for installing the truck, and eliminating ancillary work that occurred while moving to increase efficiency while widening the area of the heavy weight support point to secure additional safety. It is expected to do.
