Description

  The present invention relates to a security tool setting method and a security system used for road work such as traffic accident processing.

  Conventionally, when a disaster such as a traffic accident occurs on a highway or the like, a flame cylinder, arrow board, or cone (pylon) is located behind the lane including the disaster site in order to prevent secondary disasters caused by ordinary vehicles traveling in the vicinity. Etc. to regulate traffic.

  However, since the flame tube, the arrow board, the cone, and the like are visible signals, the effect of calling attention to a vehicle that is dozing driving or driving aside (hereinafter referred to as “runaway vehicle”) is low. On the other hand, it is difficult for road workers who are rescued from injuries, removed accident vehicles, or verified the site at the disaster site to notice the approach of a runaway vehicle. For this reason, the occurrence of secondary disasters caused by the runaway vehicles entering the disaster site is not uncommon.

  Therefore, a long cylindrical hollow body (corresponding to the hose member of the present invention) made of an elastic material was laid around the disaster site or construction site on the road, and the cylindrical hollow body was stepped on by a runaway vehicle or the like. An apparatus has been proposed in which a pressure wave generated inside the cylindrical hollow body is detected by a force wave sensor and an alarm is issued (for example, Patent Document 1).

JP 2002-22574 A

  However, in the device disclosed in Patent Document 1, a red signal lamp and a warning sounder are used in combination as a warning device, so that the vehicle enters the inner region of the cylindrical hollow body from the visible signal (the red signal light is emitted). Red light) and an audible signal (alarm sound emitted from a horn), but there is a high risk that the installation worker is involved in an accident during the installation of the cylindrical hollow body There is.

  For example, when a traffic accident occurs on an expressway, the cylindrical hollow body must be stretched 50 to several hundred meters behind the accident site in consideration of the fact that ordinary vehicles are traveling at high speed. It takes a considerable amount of time to lay a cylindrical hollow body while walking on the road, and there is a concern about the occurrence of secondary disasters because the staying time in the dangerous zone where traffic regulation is not restricted becomes longer Is.

  In addition, the work of laying the cylindrical hollow body in a long section is extremely heavy labor, and it is not easy to collect the cylindrical hollow body after the accident processing is completed, and its transportation and storage are extremely difficult.

  The present invention has been made in view of the circumstances as described above, and the purpose thereof is a hose member (tubular shape) laid on the road as a warning line that separates the traffic restriction zone and the traffic allowance zone when a traffic accident occurs. It is intended to be able to easily and quickly set security tools including a hollow body) at appropriate positions.

In order to achieve the above object, the present invention

  Hereinafter, the present invention will be described in detail with reference to the drawings. First, the road work security system according to the present invention will be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes a security vehicle, and the security vehicle 1 is provided on the road as a security tool necessary for security around the road work site. A hose member 2 for laying, a hose reel 3 for winding the hose member 2 freely, a pressure sensor 4 for detecting the internal pressure of the hose member 2, and an alarm that operates based on an output signal of the pressure sensor 4 A vessel 5 is equipped.

  The hose member 2 is a flexible tube that elastically deforms in the caliber direction when subjected to an upper load, for example, when it is stepped on a general vehicle, and has an overall length of 50 to 200 m and an outer diameter of 5 to 40 mm so that the general vehicle can be stepped on. The inside is filled with fluid (air in this example).

  The hose member 2 may have a configuration in which a plurality of hose members 2 are connected by a pipe joint. The material of the hose member 2 includes thermoplastic resins (vinyl chloride resin, polyethylene, polypropylene, butadiene resin, ABS resin, acrylic resin, PET resin, fluororesin, polyurethane resin, nylon resin, etc.), rubbers (styrene, Butadiene rubber, ethylene / propylene / diene rubber, butadiene rubber, isopylene rubber, chloropyrene rubber, butyl rubber, urethane rubber, silicone rubber, fluorine rubber, polysulfide rubber, hydrogenated nitrile rubber, acrylic rubber, chlorosulfonated polyethylene rubber, epi Chlorohydrin rubber, ethylene / acrylic rubber, etc.) or thermoplastic elastomers (vinyl chloride, olefin, urethane, polyester, polyamide, fluorine, etc.), but not limited thereto, hoses Member 2 is A flexible body as long as it is elastically deformed in the diameter direction. As a specific example, a commercially available polyurethane air hose (inner diameter 8 mm, outer diameter 12 mm, total length 100 m) is used for the hose member 2.

  Here, one end of the hose member 2 as described above is connected to the outer peripheral portion of the winding drum 31 of the hose reel 3 as a fixed end, and the other end (feeding end) as a free end leaks internal air. It is blocked so that it does not come out.

  In FIG. 1, reference numeral 6 denotes a sign for road installation in which the feeding end of the hose member 2 is locked. The sign 6 is mounted on the security vehicle 1 as a separate body from the security tool such as the hose member 2 and used. At the same time, it is unloaded from the security vehicle 1 and installed on the road. In the illustrated example, the sign 6 is a cone-shaped pylon (cone) having a lower portion of a seat plate 61 with a weight. As the sign 6, a bar is installed between two pylon. An assembly-type barricade, a foldable A-type barricade, a triangular sign board, or a standing sign with characters such as “occurrence of accident” may be used.

  On the other hand, the hose reel 3 includes a winding drum portion 31 having flanges at both ends, a pair of left and right shaft portions 32a and 32b that rotatably support the winding drum portion 31, and a bracket portion that holds the shaft portions 32a and 32b. 33 or the like. For example, as such a hose reel 3, a HATAYA hose reel (UCL-503B) can be used. Here, a bending tube 34 (elbow) is fixedly provided in the winding drum portion 31, and one end thereof protrudes from the outer periphery of the winding drum portion 31 as a connection port 34 a for connecting one end of the hose member 2. The other end of the bent tube 34 is rotatably coupled to one end portion of one shaft portion 32a that is hollow, and a seal material is interposed between the other end portions of the bent portion 34a. It is connected to the pressure sensor 4. The communication pipe 7 may be a flexible pipe or a rigid pipe. Further, the winding method of the hose reel 3 may be either manual or electric.

  The hose reel 3 has the shaft portions 32 a and 32 b directed in the vehicle width direction of the safety vehicle 1, and is fixed to the rear portion of the loading platform of the safety vehicle 1. It is possible to feed out behind the safety vehicle 1. Here, since the hose member 2 and the pressure sensor 4 are connected in an airtight and watertight manner via the shaft portion 32a of the hose reel 3 and the communication pipe 7, the pressure sensor 4 indirectly detects the internal pressure of the hose member 2. can do. As the pressure sensor 4, a diffusion type semiconductor pressure sensor, a thin film type pressure sensor, or the like is preferably used.

  As is clear from FIG. 2, the pressure sensor 4 is conductively connected to the control unit 8, and the control unit 8 is fixed on the power source unit 9 including a battery of the secure vehicle 1 and the roof of the secure vehicle 1. The alarms 5 to be provided are electrically connected.

  The control unit 8 receives the output signal of the pressure sensor 4 while supplying the power from the power source unit 9 to the pressure sensor 4 (when the signal is output from the pressure sensor 4 or the output level of the pressure sensor 4 is predetermined). The control unit 8 and the pressure sensor 4 are housed in a common protective container 10 and are secured in the vicinity of the hose reel 3. It is fixed to the loading platform of the vehicle 1.

  On the other hand, the alarm device 5 includes a light emitting device 51 that outputs a visible signal and a sounding device 52 that outputs an audible signal. As the light emitting device 51, a red rotating light or a flashing light is preferably used, and as the sound generating device 52, an air horn, an electronic horn, a speaker, an electronic buzzer, or a security vehicle whose sound pressure level at a position 10 m away is 70 dB or more. One horn is preferably used. In FIG. 2, the sound producing device 52 includes an air cylinder 52a filled with compressed air and a control valve 52b that is controlled to be opened and closed by the control unit 8, and is ejected from the air cylinder 52a when the control valve 52b is opened. The air horn outputs an audible signal by compressed air.

  According to the alarm device 5 as described above, when the internal pressure of the hose member 2 reaches a predetermined value, this is detected by the pressure sensor 4, and a drive current is supplied from the control unit 8 based on the output signal. It will operate to output visible and audible signals. The alarm device 5 is not limited to the light emitting device 51 and the sound generating device 52, and either one of them may be omitted.

  Here, a commercially available polyurethane air hose (inner diameter 8 mm, outer diameter 12 mm, total length 100 m) as the hose member 2, HATAYA hose reel (UCL-503B) as the hose reel 3, SMC's fine differential pressure sensor as the pressure sensor 4 (PSE550), SMC pressure sensor controller (PSE300) as the control unit 8, PATLITE light (KX-12-Y) as the light emitting device 51, TAKEX buzzer (AS-100L) as the sound generator 52, power supply unit When an engine starter (AX-680) manufactured by Axon Data Machine Co. was used as 9, and the hose member 2 was laid on the test road and stepped on a vehicle traveling at a speed of about 80 km / h, the light emitting device 51 and the sounding device 52 were The warning sound of 110 dB is confirmed at a point 10 m away from the sounding device 52, and the driver of the vehicle who has stepped on the hose member 2 listens to the warning sound. I was able to.

  Next, a description will be given of the setting method of the security equipment constituting the security system as described above. This method is a lane portion including the road work site in a road work site where traffic accident processing or road construction is performed. This is a method of setting a security tool for guarding as a traffic regulation zone.

  As an example, FIG. 3 shows a traffic accident scene that occurred on a road in two lanes L1 and L2 on one side. In FIG. 3, C is an accident vehicle, and the arrow indicates the direction of travel of a general vehicle. If a traffic accident occurs with one or more vehicles on the lane L1 as an accident vehicle C, the emergency rescue team rescues the injured person in the lane L1, field inspections by police officers, and accidents. Road work such as the removal of the car C is performed, but at this time, if the traffic of the general vehicle is not restricted as the traffic regulation zone Za including the lane L1 including the work site, the general vehicle accidentally enters the work site and the accident vehicle A secondary disaster may occur, such as a rear-end collision with C or a worker being bounced off.

  Therefore, when performing the road work as described above, first, as shown in FIG. 3 (a), the rear portion of the lane portion (50 to 100 m from the accident vehicle C) is defined as the passage of the security vehicle 1 equipped with the security equipment as the traffic regulation zone Za. The sign 6 mounted on the security vehicle 1 is unloaded from the loading platform of the security vehicle 1 and installed on the road behind the security vehicle 1. In addition, the feeding end of the hose member 2 is locked to the marker 6 in advance, or the feeding end of the hose member 2 is locked after installation on the road.

  Accordingly, as shown in FIG. 3B, the vehicle 1 is moved to the front of the lane portion (within about 10 m ahead of the accident vehicle C) where the safety vehicle 1 is set as the traffic regulation zone Za, whereby the hose member 2 is moved to the hose reel 3. From behind the security vehicle 1 and laying on the road. That is, when the security vehicle 1 moves forward with the feeding end of the hose member 2 locked to the sign 6, the hose member 2 is automatically drawn from the hose reel 3 starting from the sign 6, which is the security vehicle 1. It will be laid on the road along the movement route.

  On the other hand, the security vehicle 1 is stopped at the front part of the lane portion which is used as a traffic control zone Za as an alarm transmission source in a state where the hose reel 3, the pressure sensor 4 and the alarm device 5 are equipped as security tools. As a result, in the area around the accident site, in the section between the sign 6 and the security vehicle 1, the traffic restriction zone Za for restricting the passage of the general vehicle with the hose member 2 as a warning line and the traffic allowing the passage of the general vehicle are allowed. It is divided into an allowable zone Zb.

  A hose reel different from the hose reel 3 is mounted on the security vehicle 1, and a known light-emitting hose (a light-transmitting hose with a built-in light source such as an LED) is wound around the hose reel 2. It is preferable that the light emitting hose is laid along the hose member 2 in conjunction with the laying. According to this, the visibility of the traffic regulation zone Za for the driver can be improved.

  Here, if a general vehicle enters the traffic regulation zone Za by mistake, the hose member 2 is stepped on by the general vehicle, and the stepped portion is crushed by elastic deformation in the caliber direction. As a result, the internal pressure of the hose member 2 increases. The pressure increase is detected by the pressure sensor 4 as the dynamic pressure of the fluid in the hose member 2 and a shock wave, whereby the alarm device 5 is activated to issue an alarm. For this reason, the worker in the traffic regulation zone Za can evacuate to a safe place immediately, and the vehicle approaching the traffic regulation zone Za can be stopped suddenly before colliding with the worker.

  When laying the hose member 2, if a part of the hose member 2 is not drawn out and remains on the hose reel 3, the end of the hose member 2 may be crushed and the pressure sensor 4 may not be able to detect the pressure. It is important to use the member 2 in a state where the member 2 is fully extended from the hose reel 3. For this purpose, the sign 6 is installed at a position longer than the total length of the hose member 2 at the rear of the accident site or the construction site, for example, a position indicated by a dotted line in FIG. The security vehicle 1 may continue to move forward in the state where it is in a state where the sign 6 is dragged to move the position forward. Further, as shown in FIG. 3 (b), a sign object 6a different from the sign object 6 is installed along the hose member 2 laid at the boundary between the traffic regulation zone Za and the traffic allowance zone Zb. Is preferred.

  The preferred embodiment of the present invention has been described above, but the inside of the hose member 2 is not limited to being filled with air, and may be filled with other gases or liquids.
