Description

The present invention relates to a device moving attachment / detachment jig that can be attached to / detached from the adjuster in order to move the device provided with the adjuster.

Forklifts, pallet jacks, cranes, etc. are generally used because the movement and installation of work equipment in factories is heavy. However, for movement and installation work in a narrow space where such a carrier cannot be used, a crowbar or a jack is used instead of a forklift or the like. However, there is a problem that such transportation work takes time and places a heavy burden on the operator. Therefore, as another means, it is conceivable to retrofit the casters to the working device. However, the addition of the caster mounting structure leads to an increase in the cost of the working device even though it is rarely mounted. Moreover, when moving with casters, the length of the leveling bolt was once shortened in order to transfer the weight of the work equipment, and it was necessary to re-adjust the height and level the adjuster from the beginning after installation.

The following Patent Document 1 discloses a caster device that can be attached to and detached from the adjuster device. In the adjuster device that adjusts the height of the work device, the base is fixed to the lower surface of the work device by screwing the screw part, the leveling bolt is screwed into the base, and the cylindrical shape that can rotate with respect to the base. The outer cylinder is fitted. On the other hand, the caster device can be opened and closed, closed by wrapping the outer cylinder with an open sandwich, and attached to the adjuster by tightening the buckle mechanism. Then, by raising the leveling bolt and transferring the load of the working device to the caster device, the working device becomes movable.

Japanese Unexamined Patent Publication No. 2007-18631

The conventional example of the above publication is preferable in that it is not necessary to provide a caster mounting structure for the working device, but the structure of the adjuster device and the caster device is complicated, which increases the cost. Further, even in such a conventional example, when the device is moved, the weight of the working device is transferred from the adjuster device to the caster device, so that the adjuster is temporarily contracted and the height is adjusted again at the installation position after the movement from the beginning. You will have to start over. Adjusting the height of the work device and leveling it was a troublesome work that required time and labor for the operator because fine adjustment was repeated for a plurality of adjusters.

Therefore, an object of the present invention is to provide a device moving attachment / detachment jig having a simple configuration in order to solve such a problem.

The device moving attachment / detachment jig according to the present invention has a base plate having a pair of screw holes and a notch for a leveling bolt that supports the device between them, and a screw that is screwed into the screw hole of the base plate. It has a pair of caster members provided with a tightening nut for which a portion is projected and screwed from the upper surface side of the base plate into the screw portion that penetrates the screw hole.

The device moving attachment / detachment jig of the present invention has a simple structure and can be mounted without a mounting structure on the device side, and is a cost-saving moving means. Then, the leveling bolt that supports the device can be moved as it is without changing the state.

It is a side view which showed the working device at the time of moving which attached the attachment / detachment jig for moving a device. It is an enlarged view which showed the attachment / detachment jig for moving a device attached to an adjuster. It is a top view which showed the attachment / detachment jig for moving a device. It is a side view which showed the caster which comprises the attachment / detachment jig for moving a device. It is a figure which showed the 2nd Embodiment of the attachment / detachment jig for moving a device. It is a figure which showed the 3rd Embodiment of the attachment / detachment jig for moving a device.

An embodiment of a device moving attachment / detachment jig according to the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a working device with an adjuster. In this working device 1, the reversing mechanism 4 is mounted on a frame structure pedestal 3, and adjusters 5 are attached to four vertical frames 11 located on the front, rear, left and right sides of the pedestal 3. Therefore, the working device 1 adjusts the four adjusters 5 at the installation position to adjust the height of the reversing mechanism 4 and level the work device 1.

The working device 1 does not have casters. Therefore, when moving, a forklift, a pallet jack, a crane, or the like is mainly used, and the lifted state is transported to a target position. However, depending on the installation environment, it may not be possible to insert a forklift or the like, and it may not be possible to lift and transport the work device 1. Therefore, in the present embodiment, we propose a device moving attachment / detachment jig (hereinafter, referred to as “moving jig”) 6 that attaches wheels to the working device 1 only when moving. FIG. 2 is a side view showing a moving work device 1 to which the moving jig 6 is attached.

Since the moving jig 6 moves while supporting the target device, it is attached to four places in the front, rear, left, and right. The work device 1 is attached to all four adjusters 5, but even if the number of adjusters 5 increases to six or eight, for example, it may be attached to at least four places in order to move in a stable state. The moving jig 6 of the present embodiment makes it possible to move the working device 1 while maintaining the adjusted state regardless of the attachment of the moving jig 6, especially for the adjusted adjuster 5.

FIG. 3 is an enlarged view showing the moving jig 6 attached to the adjuster 5, and shows the lift state in which the working device 1 is movable. The moving jig 6 uses a rectangular plate material in which the central portion in the longitudinal direction (horizontal direction in the drawing) is recessed as a base plate 21, and two casters 22 are attached to the base plate 21. FIG. 4 is a plan view of the moving jig 6 showing the base plate 21. The central portion of the base plate 21 whose height is lowered is a load receiving portion 211 which directly receives the load of the work device 1, and a notch portion 215 is formed in the width direction (vertical direction in FIG. 4). .. The notch portion 215 is a central position in the longitudinal direction, and is notched from one side to the central portion in the same direction in the width direction.

The notch 215 is formed with a width slightly larger than the diameter of the leveling bolt 501 of the adjuster 5, and as shown in FIG. 4, the inserted leveling bolt 501 is located at the center in the width direction of the base plate 21. A substantially T-shaped positioning member 23 is provided in the notch portion 215. The positioning member 23 is fixed to the side surface of the base plate 21 in the width direction by bolting, and the insertion portion 231 is fitted into the notch portion 215. The tip of the insertion portion 231 is recessed in an arc shape, and the arc portion at the back of the U-shaped notch portion 215 and the leveling bolt 501 are held in a circumferential shape.

The base plate 21 has wheel support portions 212 on both sides in the longitudinal direction sandwiching the load receiving portion 211, to which casters 22 having lift bolts 372, which are screw portions for attachment, are assembled. Therefore, the wheel support portion 212 is formed with screw holes 217 at symmetrical positions with respect to the notch portion 215, and the lift bolt 372 is screwed into the screw holes 217. When the moving jig 6 is attached to the working device 1, the pair of lift bolts 372 and the leveling bolt 501 between them are located substantially in a straight line in the longitudinal direction.

Here, FIG. 5 is a side view showing the caster 22 of the moving jig 6. In the caster 22, the wheels 31 are pivotally supported by the axle 33 with respect to the caster body 32, and the mounting plate 35 is rotatably assembled to the caster body 32 via the thrust bearing 36. Such a configuration is a configuration of a general plate type caster, but the caster 22 of the present embodiment is further provided with an elevating screw member 37. The lifting screw member 37 is formed by integrally forming a lift bolt 372 with a hexagonal hole on the fixing plate 371, and the fixing plate 371 is fastened to the mounting plate 35 by a bolt so as to push the lift bolt 372. It is one.

The moving jig 6 is a jig that raises and lowers the base plate 21 through the screw holes 217 by rotating the lift bolt 372 with respect to the base plate 21. The lift bolt 372 has a hexagonal hole formed at the top, and is rotated in a predetermined direction by inserting a wrench into the hole and turning it, and is screwed by a base plate 21 (screw hole 217) in a non-rotating state according to the rotation direction of the lift bolt 372. The wheel support portion 212) is displaced in the vertical direction. A tightening nut 38 is screwed into the lift bolt 372 that penetrates upward from the base plate 21 so as to stabilize the wheel support portion 212 at the position of the displaced lift bolt 372.

Subsequently, the movement of the working device 1 using the moving jig 6 will be described. In the working device 1 shown in FIG. 1, the height and leveling of the reversing mechanism 4 have already been adjusted by the adjuster 5. In moving the working device 1 to another place, the moving jigs 6 are attached to the leveling bolts 501 of the square adjusters 5. First, the moving jig 6 from which the positioning member 23 is removed from the base plate 21 is arranged so that the leveling bolt 501 of the adjuster 5 relatively enters the depth of the notch 215. At that time, in the caster 22, the lift bolt 372 is screwed into the screw hole 217 in the direction of shortening the distance between the wheel 31 and the base plate 21 so that the wheel 31 does not get caught on the floor surface 100.

Next, the positioning member 23 is fitted into the notch 215 and bolted to the base plate 21. As a result, the base plate 21, that is, the moving jig 6 is restrained by the leveling bolt 501. Then, the lift operation of the work device 1 that turns the lift bolt 372 in the direction in which the wheels 31 are separated from the base plate 21 is performed. When the lift bolt 372 is extended and displaced in the direction in which the wheel 31 is separated from the base plate 21 (wheel support portion 212), the caster 22 comes into contact with the floor surface 100 and is in a stretched state with the base plate 21. In the lift operation, the lift bolt 372 is further extended and displaced from that state.

In the moving jig 6, the base plate 21 (load receiving portion 211) is in contact with the fastening nut 502 on the lower surface of the frame 11. Therefore, when the lift bolt 372 is extended and displaced while receiving the load of the work device 1 on the pair of casters 22, the frame 11 is lifted and the adjuster 5 is lifted away from the floor surface 100. The work device 1 is supported by the moving jig 6 as shown in FIG. 2 by performing the same lift operation on the four moving jigs 6, and can be moved by the casters 22.

Therefore, the operator can move the work device 1 to a target place simply by attaching the moving jig 6 even in a narrow place where a forklift cannot be inserted, for example. Moreover, although it is a movement in which the caster 22 is attached, it is not necessary to provide the caster attachment structure on the work device 1 side. The moving jig 6 can be provided at low cost because its structure is simple, the number of parts is small, and a general-purpose product can be used. Further, even when the lower surface position of the frame 11 is low as in the work device 1, the moving jig 6 can be attached by the step between the load receiving portion 211 and the wheel supporting portion 212. In particular, since the moving jig 6 can be mounted while keeping the state of the adjuster 5 as it is, there is no need to redo the troublesome work such as adjusting the height of the working device 1 and leveling the work device 1 when installing after moving. ..

Next, a modified example of the device moving attachment / detachment jig of the first embodiment will be described. FIG. 6 is a diagram showing a second embodiment of the device moving attachment / detachment jig corresponding to FIG. 3 of the first embodiment. The device moving attachment / detachment jig (hereinafter referred to as "moving jig") 7 is a moving jig 6 of the first embodiment to which a load receiving nut 27 is added. In the moving jig 6 of the first embodiment, the base plate 21 applied to the fastening nut 502 on the lower surface of the frame 11 receives the load of the working device 1. Therefore, two lift bolts 372 must be extended according to the length of the leveling bolt 501 (the length from the fastening nut 502 to the foot 503 extending downward). In this respect, the moving jig 7 is configured such that the load receiving nut 27 also used for height adjustment receives the load of the working device 1 and the lift operation is performed by the load receiving nut 27.

As the load receiving nut 27, a split nut having a structure in which half-split members can be opened and closed so that the load receiving nut 27 can be attached to and detached from the leveling bolt 501 is used. In the lift operation using the load receiving nut 27, in the caster 22, the fixing plate 371 is overlapped with the base plate 21, and the lift bolt 372 is projected upward long. Since a convex portion 373 is formed on the upper surface of the fixing plate 372 so that the lift bolt 372 penetrates, the convex portion 373 is fitted into the concave portion formed on the lower surface side of the wheel support portion 212.

The moving jig 7 is attached so that the leveling bolt 501 of the adjuster 5 is relatively inserted into the notch 215 of the base plate 21, and the positioning member 23 is fitted into the notch 215 to fit the base plate. It is bolted to 21. Then, on the upper side of the base plate 21, the load receiving nut 27 is fitted so as to be screwed into the leveling bolt 501. The load receiving nut 27 is turned by using a wrench in the direction of lowering the leveling bolt 501, and is further turned even after the wheel 31 hits the upper surface of the base plate 21 in a grounded state. However, since the load receiving nut 27 cannot be lowered any further, the leveling bolt 501 is raised and the adjuster 5 is lifted away from the floor surface 100. Such a lift operation is performed in the same manner for the four moving jigs 7, and the work device 1 can be moved by the casters 22 as in the moving jig 6 shown in FIG.

Therefore, in the moving jig 7, the load receiving nut 27 sandwiches the stop nut 505 of the adjuster 5 and the base plate 21 (load receiving portion 211), so that the adjuster 5 and the moving jig 7 are connected to each other during lifting. Stability is achieved. Further, the load receiving nut 27 rotates while being in contact with the upper surface of the base plate 21 having the notch portion 215, but since the positioning member 23 is fitted in the notch portion 215, the load receiving nut 27 can rotate without being caught. Further, since the moving jig 7 supports the working device 1 under the leveling bolt 501, the moving jig 7 can be moved in a low and stable state. Further, as in the first embodiment, the moving jig 7 that can be easily attached can be provided at low cost. Further, it is not necessary to redo the troublesome work such as adjusting the height of the work device 1 and leveling it from the beginning when installing it after moving.

Next, FIG. 7 is a diagram showing a third embodiment of the device moving attachment / detachment jig corresponding to FIG. 6 of the second embodiment. The device moving attachment / detachment jig (hereinafter, referred to as “moving jig”) 8 is a moving jig 6 of the second embodiment to which a tightening nut 28 is added. The load receiving nut 27 and the tightening nut 28 sandwich the base plate 21 from above and below, and the tightening nut 28 is also divided into a structure in which half-split members can be opened and closed so that they can be attached to and detached from the leveling bolt 501. Nuts are used.

In the lift operation of the moving jig 8, the state of the caster 22 is adjusted by the rotation of the lift bolt 372 so that the fixing plate 371 and the base plate 21 are at an appropriate distance. The moving jig 8 is attached to the leveling bolt 501 as in the second embodiment, and the load receiving nut 27 and the tightening nut 28 are screwed into the leveling bolt 501 so as to sandwich the base plate 21 from above and below. .. Then, as in the second embodiment, the leveling bolt 501 is lifted by the rotation of the load receiving nut 27 using a wrench, and the adjuster 5 is lifted away from the floor surface 100.

After that, the tightening nut 28 is turned in the direction of raising the leveling bolt 501, and the base plate 21 is sandwiched and fastened. The lift operation is performed in the same manner for the four moving jigs 8, and the work device 1 can be moved by the casters 22 as in the moving jig 6 shown in FIG. In particular, the moving jig 8 can receive and support the load of the working device 1 at an arbitrary position of the leveling bolt 501, and is suitable when the leveling bolt 501 extends long from the lower surface of the frame 11. .. As in the first embodiment, the moving jig 8 can be provided at a low cost so that it can be easily attached, and the height of the working device 1 can be adjusted or leveled when the moving jig 8 is installed after the movement. There is no need to start over from the beginning.

Although one embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention.
For example, in the second and third embodiments, a detachable split nut is used for the load receiving nut 27 and the tightening nut 28, but a normal nut is screwed into the leveling bolt 501 in advance. May be good.
Further, since the positioning member 23 stabilizes the mounting state of the moving jig 6, the base plate 21 is firmly attached with the upper and lower nuts 207, 505 or 27, 28 as in the second and third embodiments. It is not necessary when it is sandwiched. Also in the case of the first embodiment, the shape at the back of the notch 215 may be configured such that the fastening nut 502 is fitted and the positioning member 23 is omitted.
