BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on the embodiments shown in the drawings.

FIG. 1 shows a cone 1 and a moving tool 2 installed on the road.
Indicates the usage state of.

The cone 1 is formed in a known conical shape, and its main body 1a is made of synthetic resin. An outer surface of the head of the cone 1 is covered with an attracted member 3 made of a magnetic material such as an iron material that is attracted to an electromagnet, as shown in FIG. The attracted member 3 is formed in a conical cap shape composed of a top plate portion 3a and a side plate portion 3b, and is covered on the head of the main body portion 1a of the cone 1 and fixed to the main body portion 1a with screws 4. There is.

The attracted member 3 may be fixed by insert molding which integrates the attracted member 3 when the main body 1a of the cone 1 is molded, as shown in FIG.

Next, the moving tool 2 will be described with reference to FIGS.

The operating rod 5 of the moving tool 2 is formed of a pipe having a predetermined length, for example, a length of about 50 cm, and a hand-held portion 6 on the base side thereof is bent at a substantially right angle to the operating rod 5. It is fixed in. The hand-held portion 6 is formed so as to face downward during work. The handheld portion 6 is provided with a switch 7.

A suction portion 9 is attached to the tip of the operating rod 5 by a connecting portion 8.

The connecting portion 8 is provided with a first connecting member 10 projecting from the tip of the operating rod 5, and a horizontal first rotating pin 11 orthogonal to the axial direction of the operating rod 5 is provided on the connecting member 8. A second connecting member 12 is rotatably provided on the first rotating pin 11, and a second rotating pin 13 in the horizontal direction orthogonal to the axis of the first rotating pin 11 is provided at the other end of the second connecting member 12. A third connecting member 14 is rotatably provided on the second rotating pin 13, and a substrate 15 of the suction portion 9 is fixed to the other end of the third connecting member 14 to form a universal joint. With this configuration, the substrate 15 can be vertically rotated in the axial direction (front-back direction) of the operation rod 5 and vertically rotated in a direction (horizontal direction) orthogonal to the axial direction of the operation rod 5, and in this direction. Other rotations, that is, rotations within the plane of the substrate 15 cannot be performed.

An electromagnet 16 is fixedly provided on the lower surface of the substrate 15, and by energizing the coil 16a of the electromagnet 16,
A magnetic force is generated on the lower surface 16c of the iron core 16b.

An umbrella-shaped guide member 17 is fixedly provided on the outer periphery of the substrate 15. The guide member 17 has a plurality of wire rods 17a arranged on the outer periphery of the substrate 15 at substantially equal intervals and spreads downward and fixed by welding or the like, and each of these wire rods 17a is connected by an annular wire rod 17b. Then, the diameter is increased downward and the lower side is opened. Therefore, the guide member 17 is located on the outer circumference of the electromagnet 16, and is formed so as to expand downward from the electromagnet 16 and open on the lower side.

The other end of the cord 18 connected to the coil 16a of the electromagnet 16 passes through the inside of the operating rod 5 and is connected to an appropriate position, for example, a switch 7 provided on the hand-held portion 6, and further the hand-held portion 6 To the outside, and an outlet 19 is provided at its tip. The outlet 19 is adapted to be connected to an automobile battery or other power source. The electromagnet 16 is excited (energized) and de-energized (interrupted) by turning the switch 7 on and off.

Next, the work of replacing or removing the cone 1 using the cone 1 and the moving tool 2 will be described.

A case will be described in which a large number of the cones 1 are arranged in a series at appropriate intervals on a road or the like under construction.

First, the outlet 19 is connected to a power source, and as shown in FIG. 1, a worker 22 sits on a table 21 provided at the rear of the construction vehicle 20, and the worker 22 operates the operating rod of the moving tool 2. 5 is held by the hand-held part 6. Then, the construction vehicle 20 is slowly run near the cone 1 along the arrangement direction.

Then, the worker 22 moves the operation rod 5 to position the suction portion 9 on the cone 1. Then, the tip of the operating rod 5 is lowered, and the guide member 17 is put on the head of the cone 1. At this time, since the guide member 17 has an umbrella shape that spreads downward, the work of covering the head of the cone 1 with the guide member 17 is easy.

After covering the cone 1 with the induction member 17, when the switch 7 is turned on to excite (energize) the electromagnet 16, the attracted member 3 of the cone 1 is attracted to the electromagnet 16. Then, when the tip of the operation rod 5 is lifted in this suctioned state with the switch 7 kept on, the sucked cone 1 is lifted.

Then, with the cone 1 being lifted, the cone 1 is replaced with a predetermined position and moved, or is loaded on the automobile 20 for construction. After that, the switch 7 is turned off to de-energize (interrupt) the electromagnet 16, and the cone 1 is removed from the electromagnet 16, that is, the moving tool 2.

In this way, a large number of cones 1 arranged on the road are sequentially replaced or removed while the construction automobile 20 is slowly traveling.

In such replacement work or removal work of the cone 1, even a cone located in a range that cannot be directly reached by the operator can be lifted by the operation rod 5, and the operator can use the operation rod 5. As a result, it is possible to perform work in a comfortable posture, as in the conventional case and without becoming a waist.

Further, the moving tool 2 can be formed so as to have a light weight that can be carried by a worker, and can be carried in a construction vehicle. Further, it can be formed at a lower cost than a crane.

The connecting portion 8 between the operating rod 5 and the suction portion 9 is
Since it is composed of a universal joint that can rotate in the front-rear direction and the left-right direction, even if the operation rod 5 is tilted, the suction portion 9,
That is, the electromagnet 16 and the guide member 17 are directed downward by their own weight, which facilitates the work of covering the head of the cone 1 with the guide member 17. Further, even if the sucked cone 1 swings, the swing of the operating rod 5 is absorbed by the rotation of the connecting portion 8, which facilitates the work.

Further, since the adsorbing portion 9 is prevented from rotating in the plane by only rotating the connecting portion 8 back and forth and right and left, the adsorbing portion 9 rotates in the plane and the cord 18 is rotated.
It can prevent entanglement.

In the above-described embodiment, the attracted member 3 of the cone 1 has a cap shape, and the top plate portion 3a thereof serves as the attracting surface. However, as shown in FIG. The ring-shaped member 3c located on the side surface of the portion is used as the electromagnet 1.
6 may be formed so as to be attracted to the attracted member 3 on this side surface.

[0041]

As described above, according to the present invention, it is possible to perform the work of rearranging and removing the cones arranged on the road by using the operating rod. Therefore, as compared with the above-mentioned conventional work performed by the operator by directly picking it up with the waist and the hand, there is a feature that the work can be performed easily and with less fatigue.

Further, according to the invention of claim 4, it becomes easy to bring the electromagnet provided on the operating rod close to the attracted member provided on the cone, and the workability can be further improved.

Further, according to the invention of claim 5, the workability can be further improved.
