Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for stepping and changing the angle of an ultra-heavy object for underground use, which advances an ultra-heavy object such as a shield machine or other underground machine tool, or changes the angle of the angle appropriately. The present invention provides a device for doing so.

[0002]

2. Description of the Related Art In the conventional method, iron plates are laid on the floor surface to reduce frictional resistance, and oils and fats are applied to the floor surface, which is then stepped on by a side pushing jack, roller, wire or the like, or the angle is changed appropriately. , Stepping up a dedicated underground ultra-heavy object,
I can't find a device that changes the angle in small increments.

[0003]

However, although the above-mentioned conventional construction method is effective on the ground, the stepping of a super-heavy object in the ground (including the open groove) or the change in angle by each gentle angle is performed. It requires a huge amount of area and a large amount of preparation to be repeatedly applied, and it is almost impossible in terms of cost, time, etc. Even if the cost is enormous, return the super heavy object to the starting point and move forward again. It is advantageous to It is an object of the present invention to develop a device capable of easily stepping and repeating bending of a super heavy object in the ground (including an open groove), and an object of the present invention.

Is a cross-sectional plan view of a structure using the device of the present invention constructed at an underground work site, FIGS. 6 and 7 are explanatory views of the action of a step shoe plate, and FIGS. It is a figure.

1 is composed of 4 sets of two I-shaped steels 2 each having a constant length, assembled by an appropriate number of space I-shaped steels 3, and 6000 × 5800 on the upper surface.
It is a base frame in which a steel plate 4 having a width of about mm is stretched and fixed, and slidable paired shoe plates 5, 6 and 6, 5 are provided on the lower surface of the I-shaped steel 2 at both ends. The second right and left space I-shaped steels 3 in FIG. 2 extend to the outside of the I-shaped steels 2 at the left and right ends, and a hydraulic jack 12 is provided on the lower surface of each extended portion.

Pieces 7 ... Are fixed to the upper surface of the center of the length of each step shoe plate 5, 6, 6, 5 and one end is connected to the lower surface of each of the left and right I-shaped steels 2 by a shaft 8. Each piston rod 10 of cylinder 9 ... Is connected to shaft 11 of each piece 7.
・ Connect to.

In each of the hydraulic jacks 12, the lower end surface of the ground ram 13 is usually slightly higher than the lower surface of the step shoe plate 5 or the like as shown in FIG. The lower end surface of 13 is lower than the lower surface of the step shoe plate 5 as shown in FIG. 6 to support the base frame 1 and the like on the ground. While the base frame 1 and the like are supported by the hydraulic jack 12 as described above, the cylinder 9
When the piston rod 10 is extended to move the piece 7 in the forward direction, the stepping shoe plate 5 provided with the piece 7 is moved forward, and subsequently, the piston rod 10 of the other cylinder 9 is extended to extend the other piece 7. When is moved in the forward direction, the stepping shoe plate 6 provided with the piece 7 moves forward. Here, when the ground ram 13 of the full hydraulic jack 12 is contracted, the step frame shoe plates 5, 6, 6, 5 advanced by lowering the base frame 1 etc. are grounded and all the cylinders 9 are contracted, the base frame 1 etc. Slips on the oil layer 1a and advances relatively. The amount of advance by the above-mentioned one related advance operation is about 600 mm.

Grease is applied to the upper surface of the steel plate 4 of the base frame 1 to improve sliding, and the frame 1
A super heavy object support swivel base 16 in which a central shaft 17 is rotatably fitted to the center of the base to freely change the angle is provided. On the upper surface of the swivel base 16, there is a mounting equipment 18 for mounting a super heavy load 19 such as a shield machine. When the super heavy object 19 is a shield machine, there is a turning blade 20 at the tip of the machine.

According to the present invention, the direction change of the super heavy object 19 of 200 to 300 is carried out under the operation of the small angle changing device 21. The small angle changing device 21 turns on the steel plate 4. Stand 1
6 has a plurality of small pin holes 22 arranged in a circle in the turning direction (changing direction) and has a cylinder shaft 23 of the swivel base 16 which enables a small changing angle in the horizontal direction. It is provided on both sides of the heavy-weight support swivel base 16, and the rod 25 of the cylinder is provided with a pin insertion hole 26 that matches any of the above-mentioned many pin insertion holes 22, and further, the pin insertion hole 26 and the pin insertion hole 22. It is configured by a pin 27 that can be manually inserted into either. It is also possible to provide the pin insertion hole 22 on the super-heavy object supporting swivel base 16 side and the cylinder 24 on the base frame 1 side (oppositely).

The present embodiment will be described by taking as an example the stepping and small angle deflection of the excavator at the subway construction site, which is performed by using the shield excavator 19a as the super heavy object 19. At the construction site, a concrete structure 31 provided with an entrance 32 and an exit 34 of the shield machine 19a and a walkway 33 that connects both openings at a right angle is constructed using an underground stop or the like. (Figure 5). The entrance 32, the exit 34, and the step passage 33 are provided with the shield machine 19a in the small angle changing device 21 in consideration of the economic effect.
Before and after the operation, the swivel blade 20 has a width that passes through the shield machine in the forward direction. The width is also the range in which the largest steel plate 4 of the present turning device passes through the vertical and horizontal sides.

In this case, in the base frame 1 of the present invention, the step shoe plates 5, 6 are angled so that they can step forward from the inlet 32 to the outlet 34 in the step passage 3 and the steel plate 4 is used.
The installation equipment 18 of the super heavy object supporting swivel 16 in which the central axis 17 is fitted to the center of the is directed toward the entrance 32, and the shield excavator 19a in front of the swivel blade 20 is mounted to mount it. The support swivel base 16 is bent by 180 ° (see the shield machine 19a in the center of FIG. 5), and the swivel blade 20 is bent. This deformation is caused by inserting the pin 27 through the pin insertion hole 26 of the rod 25 of the cylinder 24 into one of the pin insertion holes 22 and then extending the rod 25 of the cylinder 24 into the pin insertion hole 22 next to the rotation direction. In the contracted state of 25, pulling out the pin 27 in anticipation of matching the pin insertion holes,
The rod 25 is contracted so that the next pin insertion hole 22 and the rod 2
The operation of inserting the pin 27 into the pin insertion hole 26 of 5 is repeated, and the super-heavy object supporting swivel base 16 and the shield machine 19a.
Deflection and 180 degrees. The operation of this small angle bending angle is shown in Figure 8.
9.

The step operation is

This is as described in the section [1].
