Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flaring cylinder continuous dropping device that can continuously drop a flaring cylinder from a running vehicle when lane regulation is performed on a highway or the like.

[0002]

2. Description of the Related Art Conventionally, when performing road construction or the like on an expressway or a general road, lane regulation of a vehicle lane has to be performed before (or after). The lane regulation starts much before (or after) the construction site so that no passing vehicles enter the construction site. As a procedure for lane regulation, a flaring cylinder is first placed on the road to give attention to the following vehicle, and the lane is gradually narrowed and regulated. After the flow of the passing vehicle is regulated by the flares, a color cone or lighting is installed on the road to improve the safety of the construction site.

[0003]

However, when the lane is regulated by the flares, there is a danger of personal injury such as the worker being jumped by a passing vehicle because the flares were previously placed on the road by the worker on foot. There was. Therefore, at present, the flaring cylinder is manually dropped from the flaring cylinder dropping vehicle as shown in FIG.

[0004] Referring briefly to the drawings, the construction of the flaring cylinder dropping vehicle will be briefly described. A construction vehicle such as a road construction sign vehicle is used as the vehicle 100, and the vehicle 100 is directed from the inside to the road surface.
Left and right dropping pipes 101 and 102 are arranged, and a worker manually ignites the flaring tube 103 from a passenger seat in the left and right dropping pipes 101 and 102, and then drops. The configuration of the flares 103 will be described with reference to FIG. 15. (A) is a perspective view of the flares in a packaged state,
(B) is a perspective view of the flaring cylinder in a use state with the fin 104 opened, and (C) is a cross-sectional view along XX in (B).

[0005] The flaring tube 103 is the same as the conventional flaring tube as shown in FIG. 15, and the flaring tube is provided with a closed rolling prevention fin 104 as shown in FIG. It is provided and when you drop (b)
The fin 104 is opened as shown in FIG.
5 is dropped with ignition. For this reason, there is a danger of a worker being burned at the time of ignition or a vehicle fire.

As a technique for solving such a problem, a technique described in Utility Model Registration No. 2590016 has been proposed. The flaring cylinder dropping device according to this utility model registration includes a plurality of clamping means for detachably clamping the flaring cylinder, and each of the clamping means is attached to a wrapping-type carrier at a predetermined interval, and the wrapping-type transporter is provided. A driving means for driving the body to sequentially convey each of the clamp means to an ignition position, an ignition means for sequentially igniting the igniter cylinder conveyed by the conveyance means at the ignition position, and a flaming cylinder ignited by the ignition means And a release means for releasing from the clamp means, whereby the operation of dropping the flares by a single driver can be performed easily and reliably at a target position.

However, the flaring tube dropping device registered as a utility model requires a releasing device for releasing the flaring tube ignited by the igniting device from the clamping device, and therefore, some troubles occur in the releasing device. In such a case, the ignited flares are transported again to the flares storage unit by the transport means, and there is a risk of fire spreading to other flares and a vehicle fire. In addition, since the ignition of the flaring cylinder is performed in a state of being clamped by the clamping means, in order to prevent the spread of the flame to the flaring cylinder of the storage section, every time the flaming cylinder is dropped, the ignition burner is set to `` approach → burner ignition → flaming cylinder ignition → burner extinguishing → The operation of "storage" is repeated, and the operation control of the ignition means is extremely complicated, and there is a possibility that an ignition mistake or a mechanical problem may occur. Furthermore, since it is necessary to hold the flares one by one by the clamp means, there is a problem that the work of holding the flares by the clamp means while positioning the flares is troublesome.

In view of the above, the present invention provides a flaring tube dropping means for storing and holding a flaring tube in a vehicle, and arranging a flaring tube dropping path which allows the flaring tube to drop naturally toward the road surface side continuously with the flaring tube dropping means. And by providing a stopper means for stopping the flaring cylinder and an igniting means for igniting the flaring cylinder at the lower end of the flaring cylinder dropping path, a flaring cylinder continuous dropping device capable of safely igniting the flaring cylinder at a position away from the flaring cylinder releasing means is provided. By doing so, it aims at solving the above-mentioned problems. In the present invention, the flame tube is automatically ignited automatically and continuously by remote control from the passenger seat,
Since the ignited flares can be dropped on the road at a predetermined interval on the road, it is possible to prevent a worker from being injured or injured by a following vehicle, and to prevent work accidents such as burns on the worker. Further, occurrence of a vehicle fire or the like can be prevented.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view of a flaring cylinder continuous dropping device according to an embodiment of the present invention, FIG. 2 is a side view thereof, FIG. 3 is a plan view taken along the line AA in FIG. 1, and FIG. FIG. 5 and FIG. 5 are views as viewed in the direction of arrow B in FIG.

In FIG. 1, the present flame emitting cylinder continuous dropping device is provided in a frame member 21 which is assembled by an angle or the like and has a lid 21 a which can be opened and closed at an upper portion.
As shown in FIGS. 1 and 2, a flaring cylinder dropping means 23 for continuously dropping a flaring cylinder 1 at a predetermined time interval into a flaring cylinder dropping path 22 which will be described later. And a stopper means 24 for holding the flaring tube 1 so that the flaring tube 1 (flaming tube with fins open) does not fall from the releasing passage 22 and for appropriately dropping the flaring tube, and the stopper Means 2
Ignition means 2 for igniting the flares held by 4
5 is provided. In addition, a cover or the like is appropriately attached around the above-mentioned flaring cylinder continuous dropping device to protect the inside.

Hereinafter, each component of the continuous firing device will be described in detail. On the upper part of the flaring cylinder continuous dropping device, as shown in the plan view of FIG. 3, there is provided a flaring cylinder dropping means 23 for continuously dropping the flaring cylinder 1 at a predetermined time interval into a flaring cylinder discharging path 22 described later at a predetermined time interval. Are located. This flaring cylinder dropping means 23 has a disk-like shape 2 as viewed from the top as shown in the figure.
3a, this disk is configured to be rotatable by a rotating device such as a stepping motor arranged at the center. The rotating device of the disk is not limited to the stepping motor, and various types of devices such as a device coupled to the motor via a transmission means such as a gear and a belt can be used.

In FIGS. 3 and 4, a number of notches 23b are formed around the disk 23a at equal pitches which can hold the anti-rolling fins in an open state, and the fins 104 shown in FIG. The flaring cylinder 1 is held by the notch 23b. The periphery of the disk 23a is formed as an inclined surface 23c (see FIG. 5) so that the flaring tube 1 falls under its own weight. In this state, since the cross section of the fin 104 is circular as shown in FIG. 15C, the fin 104 comes into contact with the disk 23a at one point, and the flaring cylinder 1 easily moves along the inclined surface 23c. You can slip. A holding guide 23d (see FIGS. 1 and 5) for preventing the flame tube 1 from dropping is disposed on the lower surface around the disk,
In the holding guide 23d, only a portion corresponding to a pipe 22 constituting a flaring tube dropping path to be described later is separated S as shown in FIG. 4, and when the flaring tube 1 reaches the separating portion S,
It is configured to drop by its own weight into the pipe 22 via the separation section S. The holding guide 23d is fixed to the frame member 21 by an appropriate fixing means.

Therefore, when the disk 23a holding the flaring tube 1 in the notch 23b is rotated by a stepping motor or the like, the flaring tube 1 reaching the pipe 22 is inclined by its own weight via the separation portion S of the holding guide 23d. To be dropped into the pipe 22. At this time,
By adjusting the rotation speed of the disk 23a, the time for which the firing tube 1 is dropped can be adjusted.

Although the above embodiment has been described with respect to an example in which the flaring cylinders 1 are arranged and held in a row around the disk, the flaring cylinders may be arranged and held in two rows around the disk. In this case, as shown in FIG.
One end of S (the end facing in the rotation direction) is bent 23e toward the center of the disk. By bending the end of the holding guide 23d 23e, when the flame tubes held in two rows come to the separation portion, only the flame tube on the outer peripheral side passes through the separation portion SS and falls to the pipe side as shown in FIG. Then, the inner flame tube is prevented from falling while being received by the bent end 23e, and is conveyed again by the disk. In this way, while holding the flame tubes in two rows on the disk, the flame tube 1
When dropping is performed one by one, the number of storage of the flares can be doubled as compared with the case of one row, and the working efficiency can be further improved. Note that the flaring cylinder dropping means 2
Of course, the endless chain 30 as shown in FIG.

In this embodiment, a pipe is used for the flaring tube drop passage 22 for dropping the flaring tube dropped from the flaring tube dropping means 23 (the pipe is not necessarily limited to the pipe, but has a similar function such as a gutter-shaped one). 2 and 8, the pipe 22 has a diameter such that the flaring cylinder 1 can be dropped with the fins 104 of the flaring cylinder open. The pipe 22 is a frame member 2
In FIG. 1, the upper portion is formed so as to be enlarged so as to easily receive the flaring tube 1 dropped from the flaring tube dropping means 23, and is arranged to be curved outward.

FIG. 1, FIG.
As shown in FIGS. 2 and 8, a stopper 2 which constitutes a stopper means 24 for holding the flaring cylinder 1 at the lower end position is provided. The stopper 2 is a driving means 2A for swinging the stopper 2 right and left in FIG. (See FIG. 1), and when the flaring cylinder 1 is held by the stopper 2, the ignition portion of the flaring cylinder 1 has a positional relationship corresponding to the flame of the burner 3. The stopper means 24 of the flaring cylinder 1 is not limited to this example, and has a function of holding the flaring cylinder 1 at a predetermined position of a dropping path (pipe) of the flaring cylinder 1 and dropping the flaring cylinder 1 as appropriate. If so, various other configurations such as automatic and manual can be used.

As shown in FIGS. 2, 9 and 10, a distributing means 26 for distributing the flaring cylinder 1 to the left and right of the vehicle and dropping the flaring cylinder 1 is disposed below the flaring cylinder dropping path 22.
As shown in FIG. 9, the distribution means 26 has a funnel shape with an open top, and is configured to be swingable about a shaft 28 as shown in FIG. A manual lever 27 is attached to the end of the shaft 28. By operating the manual lever 27, the lower part can be swung left and right and the flaring cylinder 1 can be split and dropped right and left. This sorting operation can be performed not only by the manual operation by the operator using the manual lever as described above, but also by using other means such as a motor or a hydraulic piston to swing the sorting means right and left. Further, it is also possible to arrange pipes exclusively for left and right without distributing means.

Next, a description will be given of the firing control circuit of the flaring cylinder with reference to FIG. In the figure, 1 is a flares,
Reference numeral 2 denotes a stopper for holding a flaring cylinder, 3 denotes a burner as an ignition means, 4 denotes an ignition transistor igniter, 5 denotes a power supply, 6 denotes a sensor (for example, an optical sensor) for checking the ignition state of the burner, 7 denotes a control circuit, and 8 denotes a control circuit. Solenoid valve,
9 is a manual valve for opening the flow path between the burner and the cylinder, 10 is a propane cylinder, and 11 is a winter heater for keeping the gas supply while keeping the propane gas warm, and these are arranged as shown in the figure. . The burner for igniting cylinder 3 adopts a continuous combustion system, and is configured to continuously emit the spark for ignition by the igniter even during combustion, so that the failure of the burner to be extinguished can be reliably prevented. .

The switch 4 of the ignition transistor igniter is turned on by a signal from the control circuit 7, and the solenoid valve 8 is opened to supply gas to the burner 3. When the gas is ignited, the flares fall and the stopper is stopped. When the temporary fall is stopped by the burner 2, the flaring tube 1 is ignited by the burner 3, the stopper 2 is removed at an appropriate timing, and the flaring tube 1 is dropped onto the road surface via the above-mentioned sorting means 26. Since the ignition of the flaring cylinder is performed in a state in which the flaming cylinder is stopped for a predetermined time by the stopper at the lower end of the dropping path, it is possible to ignite even the flaming cylinder having no igniting charge, and it is possible to prevent a fire accident during storage of the flaming cylinder. Also, since the burner is always ignited by the ignition spark of the igniter, the burner can be ignited immediately even if the fire of the burner is extinguished, and the flaring cylinder is prevented from being dropped without being ignited. I have.

Referring to FIGS. 13 and 14, a flow chart of the above-described flaring cylinder dropping procedure will be described. After the power is turned on in step S1, the on / off state of the left / right drop direction switch is detected.
The operating cylinder of the above-mentioned allocating means is operated to switch the allocating direction to the left, and a lamp indicating leftward dropping is turned on. Next, the outside air temperature is detected in step S2, and when the outside air temperature is 20 ° C. or lower, the heater 11 in FIG. 12 is turned on. When the outside air temperature is equal to or higher than 20 ° C., the process proceeds to step S3, where the solenoid valve 8 is opened, and the burner is ignited in step S4. When the burner is ignited, the combustion lamp inside the cabin turns on, and the operator confirms that the burner is ignited. In this state, the ignition spark is continuously emitted by the igniter to prevent the burner from extinguishing.

Next, in step S5, the release switch is turned on.
Then, the disk 23a holding the flaring cylinder 1 in the notch 23b
Is rotated by a stepping motor or the like, and the flaring cylinder 1 reaching the pipe 22 slides on the inclined surface 23c by its own weight via the separation portion of the holding guide 23d and is dropped into the pipe 22. Then, when the flaring cylinder is temporarily stopped by the stopper, it is ignited by the burner 3 and the process proceeds to step S6.
When the stopper 2 is opened, the flares are dropped in step S7. By opening and closing the stopper in synchronization with the rotation speed of the disk, the flaring cylinder can be continuously dropped. Further, the stopper can be controlled to be opened and closed by a timer as needed.

The operation of the continuous firing device having the above-described structure will be described. The flaring cylinder continuous dropping device assembled in the skeleton member 21 is mounted on a vehicle, and arranges the flaring cylinder dropping path 22 from inside the vehicle toward the road surface. Flame tube dropping means 2
The flaring tube 1 with the fins 104 opened is set on the disk 23a constituting the nozzle 3 and is set in a standby state. Upon arriving at the drop site,
The operator opens the manual valve 9 in FIG. 12 and turns on the power switch.

As a result, the disk 23 of the flaring cylinder dropping means 23
a starts to rotate, the flaring cylinder 1 is sequentially dropped into the pipe 22, and the dropped flaring cylinder 1 is moved to the stopper 2 in the pipe 22.
In this state, the burner 3 is ignited by a signal from the control circuit 7 and ignites the flaring cylinder 1, and the flaring cylinder 1 is dropped onto the road from the sorting means 26 via the stopper 2 which opens at an appropriate timing.

As described above, in the present invention, the inclined surface is formed around the disk, and the notches 23b for holding the flaring cylinders having the fins formed on the inclined surface are formed at an equal pitch.
Since the flaring tube is held at b, the flaring tube falls from the disk by its own weight. At this time, since the flaring cylinder is held around the disk by the holding guide for preventing the flaming cylinder from dropping, the flaring cylinder falls into the dropping path only via the separation portion of the holding guide. Thus, in the present invention, it is not necessary to clamp the flaring cylinder by the clamping means unlike the conventional apparatus, and the configuration for holding the flaring cylinder is simplified.
Further, the flaring cylinder only needs to be mounted in the notch of the disk with the fins opened, and positioning of the flaring cylinder is not required at all, and the flaring cylinder mounting operation becomes extremely easy.

The trigger signal to the control circuit 7 can be input manually or automatically, and further by a timer or the like. Further, the means for igniting the flaring cylinder 1 is not limited to gas, and various forms such as a glow plug and a nichrome wire can be used. Also, while visually checking the ignition state of the flaring cylinder 1,
It is also possible to adopt a mechanism in which the stopper 2 is manually removed and the flaring cylinder is dropped. An operation panel (not shown) is provided as necessary in the apparatus having the above-described configuration, and by operating a button on the operation panel, it is possible to variously set the firing timing of the flares.

The above-described continuous firing device is merely an example, and the present invention can be embodied in various other forms without departing from the spirit and main characteristics thereof. Therefore, the above-described embodiments are merely examples, and should not be construed as limiting. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

[0028]

As has been described in detail above, the flaring cylinder continuous dropping device according to the present invention can safely drop the flaring cylinder by remote control from the passenger seat. In the method of igniting the flares, the flares are ignited by passing through the combustion gas, so that there is no fear of burns. The combustion gas can be easily replaced by using a commercially available cartridge cylinder.
The position where the flares can be dropped on the road can be dropped on either the left or right side of the vehicle by the distribution means, so that the flares can be freely dropped on the left and right of the road surface. The drop pitch of the flares onto the road (the distance between the flares) can be automatically or arbitrarily dropped by a push button. Outside temperature is -20 due to the provision of a heater for winter
It can be used in a wide area of about ° C to + 40 ° C.
Since two rows of flares can be held around the disk, the number of flares to be stored can be increased and it is possible to cope with longer construction regulations. Ignition of the flares is stopped for a certain period of time by a stopper at the lower end of the release path. Therefore, ignition is possible even with a flaring cylinder without igniting charge, and a fire accident during storage of the flaring cylinder can be prevented. Since the burner for igniting the cylinder is of a continuous combustion type, the fire of the burner does not go out. In addition, since the ignition spark by the igniter is continuously fired even during the combustion, an excellent effect such as a problem that the burner fire is extinguished can be reliably prevented.
