The present invention relates to a moving device that can move a supporting beam easily and safely.

  For example, heavy objects such as steel frames used in bridge construction, construction work, civil engineering work, etc. are generally suspended and moved by cranes, hoists, etc. For example, a winch is used as the moving means, and many operators have moved by pulling the heavy objects.

  However, the movement by the winch requires a large number of workers, and the work efficiency is poor, and the heavy load moves in an unstable state. Therefore, it has been desired to develop an apparatus that replaces the crane, the hoist, and the winch and to improve the work.

  Accordingly, the inventors have conducted intensive research and proposed a simple moving device that can move a heavy object easily, safely, and smoothly, and a method for using the same (for example, see Patent Document 1).

According to this moving device, an elastic body is interposed in a concave space between the upper and lower flanges of the moving body, and by extending the elastic body, the heavy moving body can be moved easily, safely and smoothly. it can.

In this way, as shown in FIG. 8, the truss support beam 1 can be moved in the right-angle direction with the moving devices attached to the four ends of the truss support beam 1. In this state, the truss support beam 1 can be moved with an angle by shifting the plate-like base portion 81 of one angle adjusting member 80 with respect to the plate-like base portion 81 of the other angle adjusting member 80.

  When the truss support beam 1 is moved in the inclination direction, one angle adjustment member 80 is reversed, and the angle adjustment member 80 is loosened by the fixing bolt 84 so that the inclined portion 83 is located on the truss support beam 1 side. It is fixed to. Then, with the holding portion 11 of the holding member 10 engaged with the end of the vertical piece 6 of the truss support beam 1, the hydraulic cylinder 40 is operated to extend (raise) the ram piston 43, and the cylinder The body 20 and the holding member 10 are raised, and the upper end surfaces of the holding member 10 (the upper end surfaces of the holding portion 11 and the connecting piece 12) are brought into contact with the lower surface of the upper flange 4. In this state, the handle 32 of the fixing screw member 30 is operated to fix the holding portion 11 of the holding member 10 and the vertical piece 6. At this time, the fixing bolt 84 is fastened with the end of the inclined portion 83 extending to the other end of the plate-like base 81 of the angle adjusting member 80 being in contact with the edge of the lower flange 5 of the truss support beam 1.
