Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of a temporary structure road for constructing a temporary passage for road construction, embankment construction, ship deck construction, etc.

Figures 1 to 6 show a conventional temporary structure road, in which the horizontal floor (d ), a group of gate-type movable parts (P) for constructing straight passages, and a sacro-slanted floor plate with running wheels (e) at both ends (a movable block (with force) for constructing an elevating road). Q) group, and the adjacent blocks of each block group are connected with connecting metal fittings (gl), connecting pins (
They are detachably connected via hl to allow slight rotational refraction around the horizontal axis perpendicular to the direction of travel and around the vertical axis. In the figure (ri is a rail.

However, in the above-mentioned conventional temporary structure roads, it is necessary to connect groups of blocks when self-propelled or transported, resulting in major damage to the device.Also, although it has turning and bending functions, it has little flexibility and can be moved in any direction. It had drawbacks such as being difficult to move.

The present invention has been proposed in order to eliminate such drawbacks, and the sloping road section is pivoted on both sides of a gate-shaped frame for constructing a straight road so that the inclination angle can be freely adjusted. This temporary structure is characterized by being equipped with a lifting device for level adjustment and a driving device for traveling.

As described above, in the temporary structure road according to the present invention, the sloped road sections are pivotally supported on both sides of the gate-shaped frame for constructing a straight road so that the slope angle can be freely adjusted. The container is made into a container by closing and contracting along both sides of the mold frame, and can be easily moved to a desired location by a traveling drive device provided on the frame.

After moving to the desired location in this way, the level ml
Adjust the gate-shaped pedestal to the specified level using the lifting device,
By developing the sloping road portion at a required inclination angle with respect to the gate-shaped trestle, a temporary structure road is constructed by the sloping road portion and the gantry-shaped trestle, which requires a large number of block groups. The structure is significantly simpler than the conventional temporary structure road, and it can be easily moved to any location by the traveling drive device.

Furthermore, the present invention has many advantages, such as the fact that the gate-shaped frame allows work such as road construction to be carried out under the gate frame even in rainy weather.

The illustrated embodiments of the present invention will be described below.

(A) is a gate-type frame for configuring a straight road with columns (2) fixed to the four corners of the ceiling part (1), and the base end of the sloped road part (B) is connected to the frame through pins (3). 4) is rotatably supported on the upper part of the column (2). The inclined road portion (B) is a flat rectangular cylindrical tapered piece with an open end (4α) (4b).
)--(4tt) fitted in a telescopic tube type,
The wire connected to the chimney-shaped piece (4α) at the tip is sequentially inserted through the hole in the bottom piece of each tapered piece and wound around a drum (not shown) provided on the pedestal, and the wire is wound by the drum. The inclined road portion (B) is expanded and contracted by returning and rolling it up. Furthermore, the inclined road section (B) has an angle adjustment mechanism (5) consisting of a hydraulic cylinder and a link mechanism.
The legs can be opened and closed at any angle of inclination.

A running wheel (61) is disposed at the bottom of the column (2), and the hydraulic pressure of the hydraulic unit (7) disposed on the back side of the ceiling (1) is transmitted to the hydraulic line (8), and a hydraulic flow adjustment device (9) is installed. ), a thrust device a@, a drive device consisting of a hydraulic pipe 0υ installed from the center, and a gear device 0, drives and rotates the running wheels (6), and adjusts the hydraulic flow rate to create a thrust device (In).
The structure is such that a bearing mechanism provides a turning function using the fulcrum as a fulcrum.

A jack part (131) constituting a lifting device for level ml is provided at the lower end of the pillar (2), and is fixed to the ground during construction by a hydraulic cylinder device ([4) K, which improves the stability of the entire device. In the figure, αω is a hydraulic line (81) that transmits the hydraulic pressure to a drive device consisting of a hydraulic flow adjustment device (9) and a gear device (I) when the wheels (6) are rotating. , Jacky Club Q:
1 is a switching valve configured to transmit hydraulic pressure to the hydraulic cylinder device Q4).

OQ in the figure is the construction area covered by the pedestal (A).

Since the illustrated embodiment is configured as described above, the slope road section (B) can be closed and the supporting legs (2) of the gate-shaped frame (A) can be closed.
Combine K and retract the jack part to form the running wheel (6)
In the state shown in FIG. 8 in which the vehicle is grounded, the vehicle is connected to a trailer (not shown) via the connecting hardware (17+ (17)) installed on the support column (21) and transported to a required road construction site.

Next, the hydraulic power source of the trailer is connected to the hydraulic unit (7), and hydraulic pressure is transmitted through the hydraulic line (8) and the hydraulic flow adjustment device (9) to drive and rotate the traveling wheels (6), and the mount (3) is driven to rotate. ) is moved to the foot position, the hydraulic pressure is switched to the hydraulic cylinder device 0a by the switching valve a, the jack part α is extended, and the traveling wheel (61 is separated upward from the ground as shown in Fig. 6). .

Furthermore, insert the stopper pole (Ql) welded to the lower racket a8 protruding from the jack part α into the lower end bracket (a) of the column (2), and tighten the bolt (2υ) screwed into the bolt socket. - This is to prevent the equipment from falling in the event of a hydraulic system failure.

Next, the inclined road section (B) is opened at a required angle from the state shown in FIG. 8 to the state shown in FIG. 4 using the pin (3) as a fulcrum via the angle adjustment device (5). shaped pieces (4
a) C4b) C40) C4d) are sequentially extended and the ceiling section (IJ + surface is connected to the inclined road section (B>). At this time, the inclination angle of the L++ inclined road section (B) must be selected appropriately. As a result, vehicles can pass through, and the necessary road construction work can be carried out in the construction area αe.

In addition, in the nearby road construction area, the operation is reversed to that described above, and the vehicle is moved under its own power in the form of a container as shown in FIG.

Since the turning during self-blade movement is configured by an earring mechanism, it is possible to easily change the course. Hydraulic unit (hydraulic source of power may include a small generator and is not limited to supply from the trailer.

Although the present invention has been described above with reference to embodiments, the present invention is of course not limited to such embodiments, and can be modified in various ways without departing from the spirit of the invention. be.
