It is possible to install road cones W at intervals on the road surface G by sequentially advancing the moving vehicle A and repeating the operation.

Further, for example, after the construction is completed, as shown in FIG. 11, when collecting the road cone W installed on the road surface G, the moving vehicle A is mutually different from the forward direction as the traveling direction H when the road cone W is installed. The reciprocating swivel mechanism 2 of the swivel transfer mechanism D causes the swivel member 1 to move backward from the delivery position T on the outer side of the moving vehicle A to the installation recovery position SK on the road surface G. is pivoted, at the installation recovery position SK, the road cones W corn sensor C ₁ that approaches the bottom of the pivot member 1 is detected, sandwiching the road cones W by the holding member 3, 3 by the clamping mechanism 4 By the reciprocating turning mechanism 2, the turning member 1 holds the road cone W and turns upward from the installation recovery position SK to the delivery position T, and from the traveling direction P of the moving vehicle A and the installation recovery position SK to the delivery position T. It is configured so that the upward turning direction S toward the become opposite to each other, road cones W of the transfer position T is transferred from the transfer position T to the inside of the takeout storage position B _T of the moving vehicle a, road cones W is stored in the storage unit B via take-out storage position B _T, sequentially, be sequentially recovered road cones W placed at intervals on the road surface G by progress and the repeat operation of the moving vehicle a it can.

Accordingly, as shown in FIG. 10, when installing the road cone W on the road surface G, and proceeds to move the vehicle A in the traveling direction H, reservoir road cone W is the transfer part via the takeout storage position B _T of B The road cone W transferred to the delivery position T of C and transferred to the delivery position T is sandwiched by the holding members 3 and 3 by the pinching mechanism 4 of the swivel transfer mechanism D, and is pinched by the reciprocating swivel mechanism 2 of the swivel transfer mechanism D. 1 is turned downward from the delivery position T on the outer side of the moving vehicle A of the delivery portion C to the installation recovery position SK on the road surface G, and at the installation recovery position SK, the pinch mechanism 4 releases the road cone W and the road. The cone W is installed on the road surface G, and when the road cone W is released, the turning member 1 turns upward from the installation recovery position SK to the delivery position T, and sequentially on the road surface G due to the progress of the moving vehicle A and the repeated operation. When the road cone W can be installed on the road surface G and the road cone W installed on the road surface G is collected as shown in FIG. 11, the moving vehicle A is different from the traveling direction H when the road cone W is installed. Proceeding in the opposite direction P, the swivel member 1 is swiveled downward from the delivery position T to the installation recovery position SK on the road surface G, and at the installation recovery position SK, the road cone W approaches the lower part of the swivel member 1. When this happens, the pinching mechanism 4 sandwiches the road cone W, and the turning member 1 holds the road cone W and turns upward from the installation recovery position SK to the delivery position T, and the traveling direction P of the moving vehicle A and the above installation recovery position. the upward turning direction S toward the transfer position T is opposite to each other from the SK, road cones W of the transfer position T is stored in the storage unit B via take-out storage position B _T, thereby the installation of road cones W And the collection can be performed reliably.

At this time, since the magnet 5 is provided on the holding members 3 and 3 and the magnetic body 6 capable of magnetizing the magnet 5 is arranged on the road cone W, the holding members 3 and 3 of the holding mechanism 4 hold the magnet 5. The road cone W can be held by the magnetic action of the magnet 5 and the magnetic body 6 in addition to the action, and the road cone W can be held between the delivery position T of the delivery portion C and the installation recovery position SK on the road surface G of the road. The road cone W can be reliably held when the road cone W is installed and recovered on the road surface G by turning up and down, and the road cone W is separated from the holding member 3.3 by its own weight and centrifugal force. Can be prevented and stable collection and installation work can be performed.

Further, in this case, since the magnetic body 6 is an annular material made of a metal plate, a magnetically attached structure of the magnet 5 and the magnetic body 6 can be easily obtained, and in this case, the magnet 5 is a permanent magnet. Therefore, a magnetized structure formed by the magnet 5 and the magnetic body 6 can be easily obtained.

Further, in this case, by using the magnet 5 as an electromagnet, the road cone W can be excited by energization when it is pinched, and demagnetized by non-energization when it is released, so that the road cone W can be reliably held and released. In this case, since the turning transfer mechanism D is arranged at the left and right side positions of the moving vehicle A, for example, when the traveling lane of the expressway is restricted, the traveling lane where the construction is performed is performed. When installing and collecting the road cone W on the road surface G at the boundary between the vehicle and the overtaking lane, the road cone W can be installed and collected at both left and right positions in the traveling direction, and the flexibility of installing and collecting the road cone W can be obtained. Can be enhanced.

In this case, as shown in FIG. 10, when the road cone W is installed, the reciprocating turning mechanism 2 has a traveling direction H of the moving vehicle A and a downward turning direction R from the delivery position T to the installation recovery position SK. Is configured to be in opposite directions to each other, so that it is possible to suppress the lodging of the road cone W due to the inertial force of the road cone W working due to the progress of the moving vehicle A, and it is possible to perform stable installation work. Further, in this case, since the turning speed R _V of the moving speed H _V and the pivot member 1 of the moving vehicle a is set to substantially the same speed in opposite directions to each other, road cones W acting with the progress of the moving vehicle a The lodging of the road cone W due to the inertial force of the above can be further suppressed, and stable installation work can be performed.

Further, in this case, as shown in FIG. 11, in the reciprocating turning mechanism 2, when the road cone W is collected, the traveling direction P of the moving vehicle A is opposite to the traveling direction H when the road cone W is installed. Since the traveling direction P of the moving vehicle A and the upward turning direction S from the installation recovery position SK to the delivery position T are opposite to each other, the turning member 1 is used. When the road cone W stops at the installation / recovery position SK and the road cone W approaches the swivel member 1, the sandwiching mechanism 4 sandwiches the road cone W, and the swivel member 1 swivels upward from the installation / recovery position SK to the delivery position T and moves. The traveling direction P of the vehicle A and the upward turning direction S from the installation recovery position SK to the delivery position T are opposite to each other, so that sliding of the road cone W and the road surface G can be suppressed, and the road cone W can be suppressed. Can be collected smoothly.

Further, in this case, the turning transfer mechanism D is arranged at the left and right side positions of the moving vehicle A, respectively, and the pair of turning transfer mechanisms D and D on the left and right sides are formed in a symmetrical structure, for example. When installing and recovering a road cone W on the road surface G at the boundary between the driving lane where construction is performed and the overtaking lane when the driving lane of the expressway is restricted, the other turning transfer mechanism D on the right side in the traveling direction is used. This can be done, and the flexibility of installation and recovery of the road cone W with respect to the road surface G can be enhanced.
