Description

The present invention relates to a heavy equipment moving device, and more specifically, to a heavy equipment moving device that is used to move heavy equipment equipped with crawlers.

2. Description of the Related Art Conventionally, when a heavy object is moved, it is common to move the heavy object by placing it on a cart, as described in Patent Document 1.
However, when a heavy machine is brought into a construction site, for example, the heavy machine may not be able to travel depending on the location. In such a case, the heavy machine is transported to the vicinity of the construction site by a trailer, and then loaded onto a dolly and towed by a towing vehicle to bring the heavy machine into the construction site.

Patent No. 5246620

However, while heavy equipment equipped with crawlers is being loaded onto the dolly and transported to the site, there is a risk that the heavy equipment may slip off the dolly. For example, when the towing vehicle turns right or left, the heavy equipment may skid sideways on the dolly and fall off the dolly. If the heavy equipment falls off the dolly, it is difficult to load it back onto the dolly, and it may take longer than necessary to transport the heavy equipment to and from the site.

The present invention was made in consideration of these problems, and aims to provide a heavy equipment moving device that can reduce the misalignment of heavy equipment during movement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals, and the description thereof will be omitted or simplified.
FIG. 1 is a side view showing a state in which a pile driver 100 is placed on a heavy machine moving device 1 according to an embodiment of the present invention.
The pile driver 100 comprises a main body 101, a running section 102 provided at the bottom of the main body 101 and running on land, a pile driving section 103 provided on the front side of the main body 101 and driving piles, and outriggers 104 provided at four locations on the front, back, left and right sides of the main body 101.

The running unit 102 is provided on both the left and right sides of the main body 101, and includes wheels 102a, 102a arranged at two locations, the front and rear, of the main body 101, and a crawler 102b that is hung on the front and rear wheels 102a, 102a arranged on the left and right sides. The crawler 102b is an endless track that includes a plurality of plate-shaped grounding blocks 102c arranged in a ring shape. When the pile driver 100 runs on the ground, the grounding blocks 102c of the crawler 102b touch the ground. When the front and rear wheels 102a, 102a are rotated, the crawler 102b moves in a circular motion along the rotation direction of the wheels 102a, 102a, causing the pile driver 100 to run on the ground.

When moving the pile driver 100 from a stopped state, the heavy equipment moving device 1 is placed on the crawler 102b in a portion near the bottom of the wheel 102a. For the sake of convenience in the following explanation, the direction along the rotation of the crawler 102b is referred to as the front-rear direction (X direction in the figure), the direction along the rotation axis of the wheels 102a, 102a is referred to as the left-right direction (Y direction in the figure), and the direction perpendicular to the front-rear direction and left-right direction is referred to as the up-down direction (Z direction in the figure). In particular, the side where the pile driving section 103 is provided is referred to as the front side, and the opposite side is referred to as the rear side.

Figure 2 is an exploded perspective view showing the components of a heavy equipment moving device 1 according to an embodiment of the present invention. The heavy equipment moving device 1 includes a dolly 2, a stopper unit 3 placed on the support surface of the dolly 2, and a fixing screw 4 for fixing the stopper unit 3 to the dolly 2.

The cart 2 comprises a substantially rectangular parallelepiped base 10, wheels 11 arranged on the bottom of the base 10, an axle 12 that supports the wheels 11 and is rotatably fixed to the base 10, and a turntable 13 that is rotatably placed on the top surface of the base 10.

The front side of the base 10, which extends in the left-right direction, has two extension pieces 10a that extend forward. Similarly, the rear side of the base 10 has two extension pieces 10a that extend rearward.

In the example shown in FIG. 1, the heavy equipment moving device 1 arranged at the front and the heavy equipment moving device 1 arranged at the rear have the same configuration of the stopper unit 3 described below, but the shape of the dolly is different. In this way, the configuration of the dolly in the heavy equipment moving device 1 can be any configuration as long as it includes a base to which the stopper unit 3 can be fixed and a configuration that allows the base to be moved (wheels and axles, etc.).

The stopper unit 3 includes a rectangular seat plate 20 , a rotating shaft 21 , four stopper pieces 22 , and two supports 23 that support the ends of the rotating shaft 21 .
The seat plate 20 has two cylindrical portions 20a on each of both side surfaces extending in the left-right direction. The two cylindrical portions 20a are arranged in parallel coaxially, and the axial direction of the cylindrical portions 20a is parallel to the axial direction of the axle 12. The through holes of the two cylindrical portions 20a are large enough to allow the rotating shaft 21 to be loosely fitted therein.

A hole 20b is formed in the center of the seat surface of the seat plate 20, into which the fixing screw 4 can be inserted. In addition, protrusions 20c, 20c are formed on both sides of the hole 20b in the seat surface of the seat plate 20. According to this embodiment, the protrusions 20c, 20c are formed by fixing cylindrical rod-shaped members by welding or the like. The two protrusions 20c are parallel to the axial direction of the rotating shaft 21, and the spacing between them is set so that at least one ground block 102c constituting the crawler 102b can be accommodated. In other words, the protrusions 20c can be arranged between multiple ground blocks 102c.

The rotating shaft 21 is cylindrical and is slightly longer than the left-right length of the seat plate 20.

The stopper piece 22 comprises a rectangular plate-shaped portion 22a, an extension portion 22b with an L-shaped tip formed by extending a part of one corner of the plate-shaped portion 22a along the front-rear direction, a cylindrical portion 22c formed at the tip of the extension portion 22b, and a rod-shaped handle 22d erected on the plate surface of the plate-shaped portion 22a. The cylindrical portion 22c has a through hole into which the rotating shaft 21 can be loosely fitted, and the central axis of the cylindrical portion 22c extends in the thickness direction of the plate-shaped portion 22a. The length of the cylindrical portion 22c is shorter than the length from the corner of the seat plate 20 to the end face of the cylindrical portion 20a. As shown in FIG. 2, the cylindrical portion 22c and the handle 22d extend in opposite directions, and the positions of the cylindrical portion 22c and the handle 22d are different for each of the four stopper pieces 22.

A fixing screw 25 is attached to the extension 22b of the stopper piece 22. When the fixing screw 25 is turned in the tightening direction, the tip of the fixing screw 25 protrudes into the cylindrical portion 22c.

The support 23 is formed in a U-shape and includes a rectangular rod-shaped portion 23a and bearing portions 23b extending perpendicularly from both ends of the rod-shaped portion 23a. The inner longitudinal length of the rod-shaped portion 23a is approximately the same as the length of the seat plate 20 in the front-rear direction. A through hole is formed in the bearing portion 23b into which the rotating shaft 21 can be loosely fitted.

The support 23 is placed on both left and right ends of the seat plate 20 and fixed to the seat plate 20 by the screws 24. That is, the rod-shaped portion 23a has two through holes extending in the up and down direction, and screw holes corresponding to the through holes are formed on both left and right sides of the seat plate 20. By placing the support 23 on both left and right ends of the seat plate 20, the through holes and the screw holes overlap. Then, the fixing screw 24 is passed through the through hole of the rod-shaped portion 23a and screwed into the screw hole of the seat plate 20, so that the support 23 is fixed to the seat plate 20. At this time, the central axis of the through hole of the bearing portion 23b and the central axis of the through hole of the cylindrical portion 20a coincide with each other.

Next, the assembly procedure for the stopper unit 3 will be described. First, the rotating shaft 21 is inserted into the cylindrical portions 20a, 20a on both sides of the seat plate 20. Next, the cylindrical portions 22c of the stopper pieces 22 are inserted into both ends of the rotating shaft 21. At this time, the stopper pieces 22 are selected so that the cylindrical portions 22c face inward and the handles 22d face outward. Then, the fixing screws 25 are tightened to fix the stopper pieces 22 to the rotating shaft 21.

Next, while inserting the bearings 23b of the support 23 into both ends of the rotating shaft 21, the support 23 is placed on the end of the seat plate 20 and fixed to the seat plate 20 using the screws 24. Finally, the seat plate 20 is placed on the turntable 13, and the fixing screws 4 are inserted into the holes 20b and tightened into the screw holes 13a formed in the center of the turntable 13, thereby fixing the seat plate 20 onto the turntable 13. This completes the stopper unit 3.

3 and 4 are explanatory diagrams showing a usage form of the heavy equipment moving device 1 of this embodiment.
3(a) shows the state of the heavy equipment moving device 1 before the pile driver 100 is placed on it. Before the pile driver 100 is placed on it, the heavy equipment moving device 1 has the stopper pieces 22, 22 open outward, and the rotating shaft 21 and the stopper pieces 22, 22 are positioned below the seat surface of the seat plate 20. When the stopper pieces 22 are positioned outside the seat plate 20, the extension parts 22b come into contact with the side surface of the seat plate 20, restricting further outward rotation. Even if the turntable 13 rotates, the stopper pieces 22 come into contact with the main body of the carriage 2, restricting the rotation of the turntable 13.

When loading the pile driver 100 onto the heavy equipment moving device 1, as shown in FIG. 4(a), the pile driver 100 is loaded so that the protrusion 20c is positioned between the ground contact blocks 102c, 102c of the crawler 102b.

After placing the pile driver 100 on the heavy equipment moving device 1, an operator holds the handle 22d and rotates the stopper pieces 22, 22 toward the seat plate 20 as shown in FIG. 3(b) to place it on the seat surface of the seat plate 20. At this time, since the stopper pieces 22, 22 are fixed to the rotating shaft 21, when one stopper piece 22 is rotated, the other stopper piece 22 also rotates at the same time.

Then, as shown in FIG. 3(c), the stopper pieces 22, 22 on both sides of the seat plate 20 are placed on the seat surface of the seat plate 20. As a result, as shown in FIG. 4(b), the plate-shaped portions 22a of the stopper pieces 22, 22 move above the seat surface of the seat plate 20 and are positioned opposite the side surface of the crawler 102b. This allows the stopper pieces 22, 22 to restrict lateral movement of the pile driver 100, and the restriction on the turntable 13 is released, allowing the stopper unit 3 to rotate freely.

In this way, according to the heavy equipment moving device 1 of this embodiment, after the pile driver 100 is placed on the heavy equipment moving device 1, the stopper pieces 22, 22 are positioned to face the side of the running part, which reduces the shifting of the pile driver 100 relative to the heavy equipment moving device 1 when the pile driver 100 is moving while stopped, and prevents the heavy equipment moving device 1 from slipping off the seat plate 20.

In addition, before the crawler 102b is placed on the seat plate 20 of the heavy equipment moving device 1, the plate-shaped portions 22a, 22a of the stopper pieces 22, 22 are disposed below the seat surface of the seat plate 20, so that the stopper pieces 22, 22 do not get in the way when the crawler 102b is placed on the seat plate 20. This improves the workability when placing the crawler 102b on the seat plate 20 of the heavy equipment moving device 1.
For example, by rotating the stopper piece 22 arranged in a position facing the outer side of the crawler 102b, the stopper piece 22 arranged in a position facing the inner side, which is difficult for an operator to reach, also rotates, thereby further improving the ease of rotating the stopper piece 22.

The present invention is not limited to the above-described embodiment. Next, a modified example of the present embodiment will be described with reference to FIGS.
Fig. 5 is a plan view showing the configuration of a modified example of this embodiment, and Fig. 6 is a perspective view showing the external configuration of the modified example of this embodiment. In this modified example of this embodiment, a stopper unit 3A is provided instead of the stopper unit 3 shown in Fig. 2, and in the stopper unit 3A, the seat plate 20 and the rotating shaft 21 in the stopper unit 3 are changed to a seat plate 30 and a rotating shaft 31, and the other configuration is the same as that of the stopper unit 3. In Figs. 5 and 6, the same parts as those shown in Fig. 2 are denoted by the same reference numerals, and detailed description thereof will be omitted.

The seat plate 30 is an extension of the seat plate 20 of the stopper unit 3 in the left-right direction, and in addition to the screw holes 20d, 20d (see FIG. 6(b)) corresponding to the fixing screws 24 in the seat plate 20, screw holes 30d, 30d (see FIG. 6(a)) are formed at both left-right ends of the seat plate 30. The rotating shaft 31 is longer than the rotating shaft 21 of the stopper unit 3 by the amount of the extension of the left-right direction of the seat plate 20.

Figure 6(a) shows the state in which the support 23 is positioned at the screw holes 20d, 20d and fixed with the fixing screw 24, and Figure 6(b) shows the state in which the support 23 is positioned at the screw holes 30d, 30d and fixed with the fixing screw 24. As shown in Figures 6(a) and 6(b), by changing the position of the support 23, the movable range of the stopper piece 22 in the left-right direction can be increased or decreased. In addition, at this time, the fixing screw 25 can be loosened, the stopper piece 22 can be moved left-right, and then tightened to adjust the distance between the opposing stopper pieces 22, 22.

In this way, according to the modified example of this embodiment, the distance between the opposing stopper pieces 22, 22 can be changed, so that the distance between the stopper pieces 22, 22 can be changed to match the width of the crawler, making it possible to accommodate a wide variety of crawlers.

In addition, the above-mentioned embodiment and modified examples have been described using the heavy equipment moving device 1 applied to the pile driver 100 as an example, but the heavy equipment moving device 1 of this embodiment can be applied to any heavy equipment equipped with crawlers.

The present invention is not limited to the above-described embodiment, and any modifications or improvements that can achieve the object of the present invention are included in the present invention.
