[Detailed description of the invention] Industrial application field The present invention relates to a heavy object moving device, and is particularly suitable for moving heavy objects such as bridges and submersibles formed on the ground surface onto bridge piers, carrier ships, etc. The present invention relates to a heavy object moving device.

Conventional technology When moving heavy objects such as bridges and submarine boxes formed on the ground, etc. onto bridge piers or onto carrier ships, hydraulic cylinders, etc. are used to move heavy objects at extremely slow speeds to ensure safety during movement. As a proposal for this purpose, for example,
There is something related to No. 20652.

In the heavy object moving device according to this proposal, as shown in FIG. It is supported on a shoe 2 as a mechanism, and a rod end of a drive cylinder 3 as a hydraulic drive mechanism is connected to the shoe 2.
In addition, a grip 4 as a reaction force point mechanism is connected to the cylinder end of the drive cylinder 3, and the grip 4 is connected to a flange portion of the rail 1 serving as a grip guide between the hook 4a and the bracket 4b. 1' is clamped to determine the point of reaction force when the drive cylinder 4 is compressed.
According to this proposal, the clamping pressure holding force between the hook 4a and the bracket 4b in the grip 4 is released, the drive cylinder 3 is extended, and the grip 4 is moved to a new reaction force point on the rail 1. The heavy object A is moved on the rail 1 by fixing the grip 4 at the moving part to serve as a reaction force point and compressing the drive cylinder 3.

Further, the heavy object moving device proposed in Utility Model Application Publication No. 58-161905 has a cylinder end of a drive cylinder 3 as a hydraulic mechanism in which a rod end is connected to a shoe 2 as a sliding mechanism, as shown in FIG. The locking device 5 as a reaction force point mechanism connected to the support base B has a locking piece 5c that is fitted into a locking groove 5b of a guide plate 5a fixed on the support base B. The locking piece 5c is fitted into the locking groove 5b to determine the reaction force point of the drive cylinder 3. and,
According to this proposal, the locking piece 5c in the locking device
The locking state between the locking groove 5b and the locking groove 5b is released, and the driving cylinder 3 is extended to move the locking device 5 to a new reaction force point on the guide plate 5a, and the locking device 5 is fixed at the moved position. By using the reaction force point and compressing the drive cylinder 3, the heavy object A is moved on the rail 1.
will be moved.

Problems to be Solved by the Invention However, in the proposal of Utility Model Publication No. 57-20652, the rail 1 as a sliding surface serves as a grip guide for the grip 4 as a reaction force point mechanism, so the hook 4a and the bracket 4b are When gripping the rail 1 with clamping pressure between There was a problem in that the grip 4 as a force point mechanism could not be expected to have a complete reaction force point action.

Further, according to the proposal of Utility Model Application No. 58-161905, the locking device 5 as a reaction force point mechanism locks the locking piece 5c by fitting it into the locking groove 5b of the guide plate 5a. However, if the locking piece 5c is not completely fitted into the locking groove 5b of the guide plate 5a, a cylinder that moves the locking piece 5c up and down is used. 5d, the locking device 5 floats up on the guide plate 5a, which again makes it impossible to obtain a sufficient reaction force point action, and also prevents the locking device 5 from moving to the predetermined reaction force point position in the locking groove 5b. There was a problem in that the fixing device 5 could not be easily moved and fixed.

In any of the above proposals, when the heavy object A has an extremely large weight, the drive cylinder 3 as a hydraulic drive mechanism is made large, so that it can be used as a reaction force point mechanism. It is necessary to increase the size of the grip 4 and the rail 1 or to increase the size of the locking device 5, resulting in the problem of increasing the size of the heavy object moving device and increasing costs.

Therefore, in view of the above-mentioned circumstances, the present invention aims to provide a new heavy object moving device that can move heavy objects without increasing the size of the reaction force point mechanism and without increasing the size of the rail. do.

Means for solving the problems The structure of the present invention to solve the above problems is as follows.
A sliding mechanism arranged on a sliding surface and formed to allow heavy objects to be placed on the upper surface thereof, and a sliding mechanism formed to be fixed at an appropriate position on a support base and to be movable. In a heavy object moving device comprising a reaction force point mechanism, and a hydraulic drive mechanism formed such that one end is connected to the reaction force point mechanism and the other end is connected to the sliding mechanism, the reaction force point mechanism is They are respectively arranged on a pair of guide rails extending in the direction of movement of heavy objects on the table, and a plurality of guide rails are arranged in series on each guide rail, and the sliding mechanism is provided between the pair of guide rails. It is characterized by being arranged on a positioned sliding surface.

Embodiments Hereinafter, the present invention will be explained based on illustrated embodiments.

FIG. 1 is a plan view showing the state of use of a heavy object moving device according to an embodiment of the present invention.
is about to be moved onto support stand B,
A sliding mechanism 10 is disposed on the bottom surface of the heavy object A, and the sliding mechanism 10 is placed on the rail 1.

The rail 1 extends in the moving direction of the heavy object A on the support base B, and its upper surface is formed to be smooth so as to serve as a sliding surface. Note that a sliding surface forming body (not shown) such as a stainless steel plate that can easily obtain a smooth surface may be provided on the upper surface of the rail 1. In addition, in this embodiment, the rail 1 is formed into a beam shape with an appropriately thick steel plate.
Alternatively, it may be directly disposed or fixed on the support base B, or a part of the support base B may be formed into a smooth surface and used as one part of the rail. .

The sliding mechanism 10 may be one that forms a so-called shoe (see 2 in FIGS. 5 and 6), and in this embodiment, as shown in FIG. It has a slide plate 11 made of Teflon or the like, and a slide table 12 placed on the slide plate 11. A spacer 13 made of a board or the like is arranged on the slide plate 12, and the spacer A heavy object A is to be placed on 13. Of the slides 12, the slide 12a positioned at the top has a bracket 1.
4 are connected in series, and the bracket 14 has
One end of two connecting rods 15 are connected (see FIG. 1).

Therefore, when the connecting rods 15 are indexed synchronously, the slide 12 slides on the upper surface of the rail 1, but at this time, the slide surface on the upper surface of the rail 1 is regulated by a pair of guides 16 and A ball 17 is interposed between the slide 12 and the guide 16 so that the slide 12 does not come into contact with the guide 16 (see FIG. 2).

Guide rails 1a are erected on both side edges of the rail 1 extending on the support base B.
The guide rail 1a has a reaction force point mechanism 2 which will be described later.
In this embodiment, it is integrally connected to the beam-shaped rail 1 described above. The guide rail 1a is formed to have a substantially T-shaped cross section so as to have a flange portion 1a'.

As shown in FIGS. 3 and 4, a plurality of reaction force point mechanisms 20 arranged on the guide rail 1a are arranged in series. The reaction force point mechanism 20 includes a hook 21 that comes into contact with the lower surface of the flange portion 1a' of the guide rail 1a, a bracket 22 that holds the hook, and a cylinder 23 whose cylinder end is supported by the bracket 22.
and a holding plate 24 connected to the rod end of the cylinder 23 and abutting against the upper surface of the flange portion 1a' of the guide rail 1a. The flange portion 1a' of the guide rail 1a is held between the hook 21 and the presser plate 24 by being stretched. And also the above cylinder 2
When the pressure oil is discharged from 3 and compressed, the hook 21 is released from contact with the lower surface of the flange portion 1a' of the guide rail 1a, and the reaction force point mechanism 20 is moved to another reaction point position of the guide rail 1a. It is designed so that it can be moved to.

Note that a resistance portion 21a consisting of a chevron-shaped groove or the like is formed on the contact surface of the hook 21 with the lower surface of the flange 1a', and the same is formed on the contact surface of the presser plate 24 with the upper surface of the flange 1a'. A resistance portion 24a consisting of a chevron-shaped groove or the like is formed.

Therefore, when the cylinder 23 is extended by operating the operation panel C (see FIG. 1) connected to the hydraulic power source P (see FIG. 1), a guide is inserted between the hook 21 and the holding plate 24. Flange part 1 of rail 1a
Since a' is held under clamping pressure, the reaction force point mechanism 20 can form a reaction force point at a desired position on the guide rail 1a. At this time, all of the plurality of reaction force point mechanisms 20 may be caused to act as a reaction force point, or only one of the reaction force point mechanisms 20 may be caused to act as a reaction force point.

In addition, in this embodiment, the bracket 22 is
As shown in the figure, it is formed into a single piece that allows a plurality of hooks 21 to be connected in series, but instead of this, a plurality of brackets 22 formed to correspond to each hook 21 may be integrally connected. It is also possible to form it by setting it up. Furthermore, in this example,
As shown in FIG. 4, the presser plate 24 is integrally formed so that the rod ends of the two cylinders 23 are connected together, but instead of this, the presser plate 24 is formed independently on the rod ends of each cylinder 23. It may also mean that it has been formed. Furthermore, the bracket 22 may be formed so that a bracket 22 of another reaction force point mechanism 20 according to the present invention can be further connected thereto.

Furthermore, in this embodiment, the cylinder 2
3 is pivotally supported by the bracket 22, but instead of this, the cylinder 23 may be supported by the bracket 22 in such a manner that it cannot swing. Of course.

A hydraulic drive mechanism 30 is disposed between the reaction force point mechanism 20 and the sliding mechanism 10, as shown in FIG. And this hydraulic drive mechanism 30
is composed of a drive cylinder 31 that expands and contracts by operating a control panel C connected to a hydraulic pressure supply source P, and its rod end 32 is connected to the bracket 14 of the sliding mechanism 10. It is connected to the connecting rod 15, and its cylinder end 33 is connected to the bracket 22 of the reaction force point mechanism 20 (see FIGS. 3 and 4).

Therefore, by extending the drive cylinder 31, which is the hydraulic drive mechanism 30, the reaction force point mechanism 20 can be moved on the guide rail 1a, and the reaction force point mechanism 20 can be fixed to the guide rail 1a. By compressing when the reaction force point is being applied, the sliding mechanism 10 can slide in the direction of the support base B, and therefore, the sliding mechanism 10
It becomes possible to move the heavy object A placed on the support table B toward the support table B.

At this time, the sliding mechanism 10 slides on the sliding surface that is the upper surface of the rail 1 disposed on the support base B, and the reaction force point mechanism 20 is connected to a pair of separately arranged sliding surfaces so as to sandwich the sliding surface. The flange portion 1a' is moved on the guide rail 1a, and is held under pressure from the upper and lower surfaces of the flange portion 1a'. Also,
The drive cylinder 31 as the hydraulic drive mechanism 30 is
It will be positioned on each guide rail 1a, and of course it will not interfere with the sliding of the sliding mechanism 10, and when replacing the heavy object A with one with a different capacity depending on the size of the heavy object A. Moreover, the sliding surface of the upper surface of the rail 1 is not damaged.

Effects of the Invention As described above, according to the present invention, the sliding mechanism is arranged on the sliding surface and formed to allow heavy objects to be placed on the upper surface, and a reaction force point mechanism formed to be fixed and movable; and a hydraulic drive mechanism formed such that one end is connected to the reaction force point mechanism and the other end is connected to the sliding mechanism. In the heavy object moving device, the reaction force point mechanisms are respectively arranged on a pair of guide rails extending in the direction of movement of the heavy object on the support base, and a plurality of reaction force point mechanisms are arranged in series on each guide rail. In addition, since the sliding mechanism is arranged on the sliding surface positioned between the pair of guide rails, the part where the reaction force point support mechanism moves and the part where the heavy object slides are formed independently. Therefore, damage phenomena that may occur due to the operation of the reaction force point support mechanism will not have an adverse effect on the movement of heavy objects, and therefore, sufficient reaction force point action can be expected. This has the advantage of allowing the sliding movement of heavy objects without any hindrance. In addition, since the guide rails for the reaction force point mechanism are arranged on both edges of the rail so as to sandwich the sliding surface of the rail, the number of reaction force points is doubled, and the capacity of the drive cylinder as a hydraulic drive mechanism is reduced. Furthermore, since there are multiple reaction force points formed on each guide rail, it is possible to increase the number of reaction force points, that is, increase the reaction force, and it is possible to use an extremely large This has the advantage that there is no need to increase the size of the guide rail even when moving extremely heavy objects.
