Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a security facility for construction, which is installed on the road and displays a specific area to passersby and passersby in the vicinity, and particularly displays a warning at night. It is for.

(Prior art) For example, when performing work on the road, in order to ensure safety and improve work efficiency, the work zone is divided and a marker such as a color cone is continuously provided to warn the outside. It may be installed at a specific area to clarify the area.
In such a temporary construction security facility, a light source provided in or near the sign is turned on to warn at night.

In order to display a warning at night, a plurality of light sources are blinked simultaneously or regularly through a conducting wire (electrical cord) attached to a marker arranged so as to surround the work belt. In this case, the conductors were arranged so as to form one loop, and power was transmitted from one direction.

(Problems to be solved by the invention) However, the above-mentioned work safety facility may cut a part of a series of facilities to open or remove it to secure a running path when a vehicle related to construction goes in and out. . In addition, a traffic vehicle or the like accidentally caused an accident such as a dive, which sometimes cut off a part of the facility. Therefore, the power transmission loop has no continuity, and the light source group after the breaking point, or the entire light source is turned off. For this reason, there is a problem that a passing vehicle and a passerby cannot confirm the work zone, and a very dangerous situation such as a secondary disaster occurs.

Also, when installing color cones, type A barricades, etc. over a wide area to form a security shelf, or when removing the security shelf, install a color cone from a location certified by the light source on the side where the power source is located. If this is not done, there is a problem that the light source must be installed without being turned on. This is also the case when removing color cones, etc., which hinders the safety and efficiency of installation work. The present invention is proposed to solve the above problems, and even if a part of the facility is cut off, the whole light source group is turned on without turning off the whole light source, and appropriate safety is maintained. The purpose is to provide a construction safety facility that can maintain the condition.

(Means and Actions for Solving the Problems) In order to achieve the above-mentioned object, the present invention is a construction in which a plurality of light sources are connected in a desired form and an electric circuit for illuminating them is arranged to form a night warning display group. In a security facility,
Forming the electrical circuit in a plurality of loops, at least 1
It is configured to maintain the connection between the two electric circuits and the power supply.

In this way, since one electric circuit that is always energized is formed, the lighting state for warning display can be maintained.

(Embodiment) FIG. 1A shows a first embodiment of the present invention in which color cones 1 containing lamps are arranged in series. The color cone 1 has a substantially triangular pyramid shape, and a plurality of color cones 1 are arranged at equal intervals to partition a work zone or separate roads. L indicates a lamp.

The conducting wire from the power source 2 forms a loop for each pole with an X loop formed by a wiring indicated by a double line and a Y loop formed by a wiring indicated by a single line. In this case, by connecting in-phase loops, each loop can blink in synchronism. For this purpose, in-phase connection may be performed by using a connector that connects in a fixed direction. B to C are embodiments of the connector, B is an insertion tool, C is a receiving tool, and D is a front view of B. 7 is an outlet. Of course, it is not limited to the in-phase loop connection.

FIG. 1E is an enlarged view of the vicinity of the color cone 1 and the lamp 3 installed in the head thereof. The color cone 1 and the cone bar 4 are connected to the same phase by using odd-shaped connectors 5 and 6.

With such a configuration, when the power is supplied from the power source, the lamps in the color cone 1 are turned on all at once. In this state, when the construction vehicle goes in and out of the site, the electric cord may be temporarily removed via the outlet 7 to separate a part between the color cones 1 forming the safety fence. That is, the corresponding portions of the X loop and the Y loop are cut off and the respective loops become incomplete loops, but even in this case, the lamps after the cut portion are not turned off. For example, consider the case where the electrical cord is removed at the K point. The current in the direction indicated by the double-line arrow in the X loop causes the three lamps before the K point to continue to light up, while the single-line arrow indicates The two lamps after the point K are lit by the current in the direction. Thus, even if the current path from one direction is cut off, the current path from the opposite direction of the loop is maintained, so that the lamp does not go out. This also applies to the Y loop. Therefore, even if any part of the loop-shaped wiring is removed, the electric power is supplied to the subsequent wiring portions, the lamp is not turned off, and the safety problem does not occur.

FIG. 2 shows a second embodiment of the present invention, which is arranged in a ring shape by connecting the plug 9 and the outlet 10 one after another to form a power transmission state from the cable drum 8. The six color cones 1 are in a normal lighting state. Then, two loops of the A system (double line display route) and the B system (single line display route) are formed, but the lamps A ₁ to A _{6 of the} A system are in a lighting state.

FIG. 3 shows the relay wiring provided in the color cone 1 having the lamp A ₆ in this state. At present, the A system is energized, the B system is in a simple power transmission state in which the lamp is not lit, and the relay contacts 11 and 12 are attracted to the contacts 13 and 14, respectively, and the lamp 1 is lit.
15 is a coil.

Here, when the plug 9 and the outlet 10 are removed at the K point as shown in FIG. 4 for the entry and exit of vehicles and the like, the electricity of the A system is energized from the cable drum 8 to the K point. The color cone 1 will be turned off. However, since the color cones 1 are temporarily de-energized, as shown in FIG.
Since electricity does not flow to the contacts 11 and 12, the contacts 11 and 12 are attracted to the contacts 16 and 17, and the B system is switched from the power transmission state to the energized state, so electricity flows in the direction of the single line arrow, and the lamp in the color cone 1 is the B system lamp B ₁ , B ₂ and B ₃ are lit.

As described above, in the present embodiment, since the A system and the B system are in the power transmission state, respectively, even when the electric circuit is cut off in the middle, one of them is kept in the lighting state by operating the relay.
It is possible to turn on the other and not turn off the light.

(Effect of the Invention) According to the present invention as described above, even if the electric wire is cut at any point in the series of electric circuits related to the security facility such as a security fence, electricity flows from the opposite direction of the loop wiring or is cut by the switching means. The electric circuit after the point can be energized, and the lamp can be prevented from being turned off. Therefore, it is possible to avoid a disaster such as a rushing accident of a passing vehicle and a secondary disaster because it is difficult to check the work zone because a trouble occurs in the lighting of a safety fence or the like and a wide range of the unlit portion.

In addition, even when installing and removing safety fences, etc., it is possible to carry out the work while keeping part of the electric path lit, so safe and efficient work can be performed.
