DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a walking frame that can be used at a construction site and can be moved as if it were walking while carrying a crane, a support car, an elevated work platform, etc. on it.

Currently, so-called prefabricated buildings constructed using cast concrete plates and prefabricated building materials have come into widespread use.

This type of housing construction has the following characteristics: the period required for on-site construction is extremely short, and a variety of standards can be selected.

However, there is a drawback that construction cannot be carried out in places where construction machinery for this construction cannot be brought in. In other words, cranes used at construction sites,
Elevated work platforms, etc. are used while mounted on a vehicle, so construction cannot be carried out unless the vehicle can enter. Generally, along the construction site,
The most basic condition for construction is that there is a road with a certain width or more, and that a crane or the like can be operated while a vehicle is stopped on the road.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an object of the present invention is to provide a walking platform on which a crane, a sigibel car, an elevated work platform, etc. used at a construction site can be carried while walking.

In order to achieve the above object, the walking frame according to the present invention includes a frame on which a construction machine can be mounted, a supporting jack provided on the frame, and at least two fasteners for the frame.
A walking jack is provided on the pedestal so that it can take two relative positions, and with the pedestal supported by the supporting jack, the walking jack is moved relative to the pedestal, and the walking jack and the pedestal are moved relative to each other. It is composed of a relative position adjusting device that changes the position of the walking jack, supports the pedestal with a walking jack, floats the supporting jack, and moves the pedestal to change the relative position of the walking jack and the pedestal.

According to the above configuration, the pedestal on which the construction machine, etc. is mounted is transported by a truck or the like to a location close to the construction site, and then the pedestal and the truck, etc. are separated, and the pedestal on which the construction machine, etc. is mounted is moved to the site by walking. The above problem can be solved.

It is a hydraulic cylinder for The hydraulic cylinder 303 is a turning hydraulic cylinder for adjusting the angle between the upper assembly and the lower assembly. These hydraulic cylinders are controlled by an operator operating a multi-control pulp.

Next, the operation of the apparatus of the embodiment will be explained.

FIG. 3 is a schematic diagram for explaining the state in which the embodiment device of the walking frame is separated from the truck.

In Figures 3A and B, the walking platform is the cargo platform 11 of the trunk 1.
The state shown is that it is installed in the .

10 is the driver's cabin of the truck. Transport the walking platform to a location as close as possible to the site using truck 1. Usually, construction machines such as cranes are integrally mounted on this walking frame, but these machines are omitted in this figure, and only the main parts of the walking frame are schematically illustrated.

After transporting the walking platform to the site or the closest location to the site, place the jacks 21 at positions corresponding to the supporting jacks on both sides of the truck bed 11, as shown in Figure 3C and D (7). Place .22. Then, the beam is pulled out from the support jack receiver of the lower assembly, and the support jacks 203 to 206 are brought onto the jack stand. Then, using the above-mentioned hydraulic system, the supporting jaw, key 203
206 is activated and the walking frame is supported on the jack table 21, 22, etc. In this state, the truck is moved forward to complete the separation from the trunk of the walking platform.
