Description

[Detailed Description of the Invention] This invention relates to a moving device for moving a structure on which an oil or geothermal well drilling rig is mounted.

When drilling oil wells or geothermal wells, a drilling rig equipped with various drilling machines is installed in the drilling tower, but when drilling several wells over a short distance at a drilling site, generally Figure 1, 2nd
As shown in the figure, this is done by moving the structure 2 while the excavation tower 1 is placed on top of the structure 2. Usually, the moving distance at one time is within a range of about 10 m, so conventionally A long slide base 3 with a certain amount of movement room is integrally constructed, a round bar 4 is laid as a roller on this slide base 3, a structure 2 is placed on this round bar 4, and it is fixed on the slide base 3. The structure was moved by being towed by a towing device 5 or a winch.

However, in this method, (1) the round bars 4 are simply laid out, so as the structure 2 moves, the rolling of the round bars 4 becomes biased, resulting in the structure being biased in a diagonal direction; (2) the round bars As a result, the load distribution on the structure 2 becomes uneven as a result of biased rolling of the round bars 4 and uneven movement (some bars roll and some bars do not roll). (3) The spacing between the round bars 4 becomes uneven. The round bars that are uneven or slanted need to be hit with a hammer to be corrected, which is inefficient and takes time and effort.
There are drawbacks such as.

This invention does not have the above-mentioned drawbacks of the conventional methods, allows structures to be moved smoothly with uniform load distribution without skewing, and can be carried out easily and efficiently. The purpose is to obtain a mobile device.

An embodiment of this invention will be described below with reference to the drawings.

Although not shown in FIGS. 3 and 4, the structure A on which the drilling rig is placed, as in FIG.
It is a frame structure made of steel that is constructed by connecting 0 and 0 with pin connections with beams 11.
It is a large structure with a width of approximately 9 m and a height of approximately 3 m. Further, each side structure part 10 has an appropriate width so that it can stand alone stably, and this side structure part 1
0 is formed by lower beams 12 such as left and right I-beams (see FIGS. 6 and 7, which will be described later).

The structures A are loaded onto a plurality of mutually connected slide bases 13 via roller tables 16 which are also connected.

The slide base 13 is connected to the lower beam 1.
It has a roughly I-shaped cross section with a supporting portion 13a on the upper surface having a width slightly wider than the width of the second flange portion 12a, and is provided in four rows facing the four rows of lower beams 12. In this embodiment, two rows of slide bases 13 corresponding to two rows of lower beams 12 of one side structure section 10 are integrated by a stay 14, and these integrated slide bases are
The left and right sides are connected by a positioning member 15, respectively. Furthermore, connection plates 13b with connection holes are attached to the front and rear ends of the slide base 13,
The slide bases 13 can be connected to each other in the length direction.

Further, as shown in FIG.
8..., and the interval between the side frames 19 of the cage 17 is equal to the support part 13a of the slide base 13.
When the roller table 16 is placed on the slide base 13 as shown in FIG.
are being contacted. Further, the side frame 19 serves as a guide when the roller table 16 moves on the slide base 13. Also, one side frame 1
Connecting holes 19a are formed at the front and rear of the roller tables 9 so that the roller tables 16 can be connected to each other via a connecting member 20 having a notch 20a.

Furthermore, side guides 21 for moving the structure A along the slide base 13 are attached to the lower beams 12 on both the left and right sides of the structure A. This side guide 21 is connected to the lower beam 12
Bracket 2 fixed with bolts to the web part of
2 is a guide roller 2 using needle bearings, etc.
3 is attached, and this guide roller 23
are arranged to face guide surfaces 24 formed on both lower sides of the support portion 13a of the slide base 13.

FIG. 7 shows a fixing device for fixing the structure A on the slide base 13 after completion of movement, and this fixing device consists of a clamp bolt 26 with a hook portion 26a at the lower end and a tightening plate 27. ,
The hook portion 26a is attached to the support portion 1 of the slide base 13.
3a on both back sides 13c, and tighten the clamp bolts 2.
A tightening plate 27 through which 6 is passed is applied to the upper surface of the lower beam 12 of the structure A and tightened with a nut 28, and the lower beam 12 is strongly pressed against the slide base 13 by the tightening plate 27 and fixed. FIG. 7 shows a cross section of the connecting portion of the roller table 16. After tightening with the nut 28, a wedge 29 is driven through the notch 20a of the connecting member 20 between adjacent roller tables 16. , lower beam 12 (therefore structure A
) more firmly to the slide base 13.

Next, the work to move structure A will be explained.

The structure A is constructed by interposing a roller table 16 connected to the slide base 13 according to the length of the structure A, which is also connected to the slide base 13 according to the length of the structure A. When moving the structure A, a predetermined number of slide bases 13 at the front are connected according to the moving distance, and a winch base 31 equipped with a winch 30 is attached to the front end of the slide base 13.
and a positioning member 1 at the middle part in the width direction.
5, and the left and right slide bases 13 are arranged at correct intervals by the positioning member 15.

Next, the roller table 16 is further placed on the slide base 13 in front of the roller table 16 on which the structure A is already placed on the slide base 13, and this is connected to the existing roller table 16 via the connecting member 20. and connect.

Next, the structure A is towed by the winch 30 and moved forward. In this case, since the rollers 18 are in contact with the upper surface of the slide base 13 and directly support the structure A, they act as rollers, and as the structure A moves on the roller table 16, the roller table 16 itself also moves. Move on the slide base 13. At that time, the roller table 16 is attached to the slide base 1 by the side frame 19.
Since it moves straight without coming off from 3, roller 18
always maintains a right angle to the advancing direction, so the structure A is allowed to move forward without being skewed.
Note that even if the vehicle travels slightly obliquely, it is regulated by the side guides 21 and moves straight. In addition, since each roller 18 always maintains equal intervals and is perpendicular to the direction of movement as described above, the rollers 18 can be moved around the structure without irregular movement such as rolling or non-rolling. It supports the load of A evenly and allows smooth forward movement. Further, since work such as correcting the skew of the roller table 16 is not necessary, the work of moving the structure is extremely efficient.

After moving further by a desired distance, the structure A is fixed to the slide base 13 with the clamp bolt 26 and the tightening plate 27 as described above, and the winch base 31 is removed, as shown in FIG. A stopper 32 is attached to the connecting plate 13b of the slide base 13 at both front and rear ends, and a stopper block 33 is fitted between the stopper 32 and the structure A to reliably prevent the structure A from moving in the front and rear direction.

As explained above, in the moving device of the present invention, the slide base is divided into a plurality of parts, which are removably connected to each other, and a roller table in which a plurality of rollers acting as rollers are arranged in a cage. and this roller table can be connected detachably, so unlike the conventional structure that simply lays a single round bar as a roller on an integrated slide base to move the structure, Objects can be moved smoothly in a straight line without being skewed, and the load distribution on the structure will not be uneven, and the movement of the structure is extremely easy and efficient.
