Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a traveling caster device that is applied to movable formwork for constructing retaining walls, culverts, tunnels, and various other types of concrete.

In recent years, in the construction of horizontally long concrete structures such as retaining walls, soundproof walls, culverts, and tunnels, the entire formwork has been assembled on a large scale one after another in order to streamline construction and save labor. Mobile formwork construction methods, in which formwork is moved to the construction location and used repeatedly, are being implemented. As a method for moving the formwork in this construction method, one in which the formwork is moved by using a cart or the like is becoming mainstream. Most of the conventional traveling formwork devices are of the type in which the formwork is attached to a large traveling trolley in various adjustable ways, but in such formwork devices, the traveling truck only supports the formwork. In addition, since the formwork must also support the load of the poured concrete, the structure is not only strong but also the mechanism for operating the formwork is complex, making it heavy and difficult to handle. However, there are many problems, such as being expensive and requiring a large space to install the traveling trolley.

The present invention was made in order to solve the problems of the conventional traveling and moving formwork device as described above. The machine is equipped with running wheels and features that allow easy operations such as leveling and demolding the formwork, making it extremely easy to move the formwork and handle it. This device is labor-saving, can be manufactured at low cost, does not require a large space for moving the formwork, and allows formwork work to be carried out economically and efficiently. So-called jaw-shaped walls and culverts,
The present invention aims to provide a traveling caster device suitable for constructing tunnels and the like.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a vertically elongated base I7, and a support leg 3 having a wheel 2 at its lower end is attached to the lower part of the base so that it can be raised and lowered. This attachment mechanism normally involves supporting legs 3 and 3 attached to hydraulic cylinders 4 provided in the vertical direction of the script body 1 as shown in the figure.
8 However, this hydraulic cylinder 4 may be attached to the outside of the script body 1, and a screw-type cylinder may be used instead of the hydraulic cylinder 4 to adjust the elevation. You may also do so. One end of a pair of upper and lower support arms 5.6 is attached to a bin 7 at a position below the upper part of the script body 1 and at a required distance therefrom.
