Further, as shown in FIG. 5, when the bent portion 22B comes into contact with the lever 52, the lifting / lowering detecting body 49 is pushed together with the slider 19 in the direction indicated by the arrow B. At this time, the slider 19 is driven to the lowered position. This is to detect that it has been done.

  The other slider 20 does not need to perform such a detection operation using the elevation detector 49. Therefore, the slider 20 can be configured by using two identical plates 21 for the other slider 20 without using the plate 22 unlike the one slider 19.

  24, 24,... Are rollers constituting part of the sliders 19 and 20, and these rollers 24 are provided on both ends of each shaft 23 via bearings 25 as shown in FIG. It is formed as a resin roller using this resin material. These rollers 24 rotate while sliding along the guide surfaces 12C and 13C of the fixed columns 12 and 13 as shown in FIGS. 6 to 10, so that the sliders 19 and 20 move inside the fixed columns 12 and 13. It compensates for smooth up and down movements.

  .. Are pulleys provided on the sliders 19 and 20. Each pulley 26 is formed using, for example, a resin material having high wear resistance, and between the plates 21 and 22 as illustrated in FIG. It is located and is rotatably provided on the outer periphery of the shaft 23. On the other slider 20 side, a pulley 26 is positioned between the two plates 21 and is rotatably provided on the outer periphery of the shaft 23.

  As shown in FIGS. 8 and 10, a guard rope 39 (described later) is contacted or wound around these pulleys 26, and the pulley 26 follows the movement of the guard rope 39 and has a low friction around the shaft 23. Rotate in state. Thereby, the pulley 26 reduces frictional resistance etc. accompanying the movement of the guard rope 39 small.

  The weights 27 and 27 are weight adjustment weights provided on the sliders 19 and 20. Each weight 27 is formed as a rectangular block body having a weight of, for example, several kg, and is a plate as illustrated in FIG. Fastened between 21 and 22 using bolts or the like. The weight 27 is fastened between the two plates 21 on the other slider 20 side.

  A backup roller 28 is provided on the other slider 20 side. The backup roller 28 is supported on the upper end side (tip side) of a bracket 29 extending in a substantially L shape from the position of the weight 27 as shown in FIG. It is rotatably provided through a shaft 28A or the like. The backup roller 28 is in contact with or in contact with the guide surface 13D in the other fixed column 13 and suppresses the slider 20 and the roller 24 from being inclined in the fixed column 13 together with the rollers 24.

  That is, the slider 19 in the fixed column 12 is a slider 19 on the driving side that is directly influenced by the tension applied to the guard rope 39 by the rope drive device 41 described later, whereas the slider 19 in the fixed column 13. 20 is a driven side. Then, the driven slider 20 indirectly receives the influence of the tension applied to the guard rope 39 by the rope driving device 41 via the driving slider 19.

  For this reason, if the tension of the guard rope 39 becomes weak and even a slight slack or the like occurs in the rope 39, the driven slider 20 may be inclined in the fixed column 13. Therefore, the backup roller 28 prevents the slider 20 from tilting in the fixed column 13 together with the rollers 24 on the guide surface 13C side, so that the slider 20 can smoothly move along the guide surfaces 13C and 13D of the fixed column 13. It is compensated with the additional weight 30 to move up and down.

  Reference numeral 30 denotes an additional weight provided in addition to the slider 20. The additional weight 30 is positioned between the weight 27 and the backup roller 28 and is fixed in the middle of the bracket 29 as shown in FIG. 10. Further, the additional weight 30 sets the driven slider 20 together with the backup roller 28 and the bracket 29 to a weight that is approximately twice that of the driving slider 19.

  Reference numeral 31 denotes an intermediate movable strut located between the fixed struts 12 and 13 and provided in the middle of the drainage groove 7 (near the boundary of the site 1). The movable strut 31 is made of a rigid material having a high rust prevention property (for example, A rectangular pipe member made of stainless steel or the like is used to form a hollow cylinder having a square cross section as shown in FIGS. The movable column 31 has a width dimension sufficiently smaller than the groove width of the drainage groove 7, and upper and lower ends thereof are open ends 31A and 31B.

  In addition, the movable column 31 is installed such that the lower end side thereof can be raised and lowered in the drainage groove 7 via a mounting bracket 32 described later, and is either in a standing position indicated by a solid line or a tilted position indicated by a two-dot chain line in FIG. Be placed.

  When the sliders 19 and 20 in the fixed support columns 12 and 13 are both raised in the direction indicated by the arrow A to the ascending position indicated by solid lines in FIGS. 3 and 4, the lever 56 is moved by the tension applied to the guard rope 39. The spring 59 is allowed to be pushed upward in the direction indicated by the arrow A via 19 (the bent portion 22A) by being elastically compressed and deformed.

  In this case, the drive-side slider 19 moves up in the fixed column 12 before the driven-side slider 20, and then the driven-side slider 20 tends to move up in the fixed column 13. Therefore, the spring 59 is elastically compressed and deformed when both the sliders 19 and 20 are in the raised position, and allows the entire lifting detection body 49 to be displaced upward.

  Reference numeral 60 denotes a dog which is a detection target provided at the upper end of the rod 57, 61 and 62 are limit switches as detectors for detecting the displacement of the dog 60, and the limit switches 61 and 62 When the dog 60 is displaced to the positions 60A and 60B indicated by the two-dot chain line in FIG. 7 along with the upward and downward movements, this is detected and the operation of the rope drive device 41 is automatically stopped.

  The guard device 11 for a gas station according to the present embodiment has the above-described configuration, and the operation thereof will be described next.

  First, when the gas station is closed, for example, an operator at the gas station inserts a key into the operation unit 45 of the head case 42 shown in FIG. 2, and power is supplied to the electric motor 43 of the rope drive device 41 by manual operation using the key. Is input.

  Thereby, the rotary drum 44 can be rotationally driven by the electric motor 43, and the guard rope 39 is operated so that one side in the length direction is wound around the outer peripheral side of the rotary drum 44. For this reason, the guard rope 39 is pulled in the direction of arrow F in FIG. 3 so that sufficient tension is applied, and the slider 19 is driven upward together with the guard rope 39 in the fixed support column 12 on the driving side. be able to.

  When the drive-side slider 19 rises in the fixed column 12 in the direction indicated by the arrow A in FIG. 7, the bent portion 22 </ b> A provided on the plate 22 of the slider 19 is brought into contact with the lever 56 and is moved by the spring 59. The lever 56 is held in this contact state. At this time, the driven slider 20 is driven upward (in the direction of arrow A) in the fixed column 13 by the tension applied to the guard rope 39 in the direction of arrow F in FIG. It moves to the raised position indicated by the solid line and comes into contact with the upper lid 17 on the fixed support 13 side.

  For this reason, the guard rope 39 acts to push up the slider 19 on the driving side further upward by the tension applied in the direction of arrow F in FIG. 3, and the spring 59 shown in FIG. Compress and deform. As a result, the entire lifting detection body 49 is operated so as to be displaced upward against the spring 59.

  When the dog 60 provided on the upper end side of the lifting / lowering detection body 49 is displaced to a position 60A indicated by a two-dot chain line in FIG. 7, the displacement of the dog 60 can be detected by the upper limit switch 61, and the rope driving device 41. The electric motor 43 can be automatically stopped. Until the electric motor 43 is stopped, the rotating lamp 48 shown in FIG. 2 is turned on while rotating, and notifies the surrounding workers and the like that the guard rope 39 is moving upward.

  Thereby, the guard device 11 of the gas station spans the intermediate portion in the longitudinal direction of the guard rope 39 located between the sliders 19 and 20 to the raised position between the fixed struts 12 and 13 as shown in FIGS. The intermediate movable column 31 positioned between the fixed columns 12 and 13 can be raised to the standing position indicated by the solid line in FIGS.

  In this state, the guard rope 39 is intermediate between the fixed column 12 and the fixed column 13 so as to follow the drainage grooves 7 and 8 (the boundary including the corner portion 9) of the gas station shown in FIGS. It can be bridged while being stretched through the movable column 31, and for example, it is possible to block or prevent the vehicle from illegally entering the site 1 when the gas station is closed.

  Next, when opening the gas station, the operator manually operates the operation unit 45 again with the key or the like to turn on the electric motor 43 of the rope drive device 41. At this time, the electric motor 43 operates to unwind the guard rope 39 from the rotating drum 44, and the tension of the guard rope 39 is greatly reduced.

  For this reason, the sliders 19 and 20 in the fixed support columns 12 and 13 are moved to the lowered position indicated by a two-dot chain line in FIGS. In this case, the driven slider 20 is formed so as to be heavier than the driving slider 19, so that the driven slider 20 first moves to the lowered position, and then the driving slider 19 moves to the lowered position. Move up.

  And the raising / lowering detection body 49 provided in the fixed column 12 on the driving side is provided on the plate 22 of the slider 19 when the slider 19 descends in the fixed column 12 in the direction of arrow B in FIG. When the bent portion 22B comes into contact with the lever 52, the spring 54 is elastically compressed and deformed, and the entire lifting detection body 49 is displaced downward against the spring 54.

  As a result, the dog 60 provided on the upper end side of the elevation detector 49 is displaced downward to a position 60B indicated by a two-dot chain line in FIG. 7, and at this time, the displacement of the dog 60 can be detected by the lower limit switch 62. The electric motor 43 of the rope drive device 41 can be automatically stopped. In this case as well, while the electric motor 43 is in operation, the rotating lamp 48 shown in FIG. 2 is turned on while rotating to notify that the guard rope 39 is moving upward.

  The guard rope 39 is lowered to the lowered position between the fixed struts 12 and 13 as shown by the two-dot chain lines in FIG. 3 and FIG. The intermediate movable column 31 positioned between the 13 is tilted to the tilt position indicated by the two-dot chain line in FIG.

  That is, the tension applied to the guard rope 39 is weakened. Therefore, when the guard rope 39 moves in the direction of the arrow E in FIG. Therefore, a tilting force in the direction indicated by the arrow C in FIG.

  Then, as the movable column 31 is tilted from the standing position to the tilted position, the intermediate portion of the guard rope 39 can be guided into the corner portion 9 of the drainage grooves 7, 8. Is housed together with the movable column 31 in the drainage grooves 7 and 8 (including the corner portion 9) located on the boundary.

  As a result, the guard rope 39 can be satisfactorily accommodated in the drainage grooves 7 and 8 together with the movable support column 31, and the guard rope 39 can protrude from the drainage grooves 7 and 8 (including the corner portion 9). Can be prevented. As a result, the movable support column 31 and the guard rope 39 can be prevented from interfering with the passage of the vehicle, and the sales activities of the gas station can be performed smoothly.

  In addition, when the gas station is opened, a vehicle such as a passenger car driven by a customer is guided from the drainage grooves 7 and 8 illustrated in FIG. 1 to the position of the island 5 and stopped so that the vehicle is laid on the island 5. Refueling work can be performed in the state. At the time of this refueling operation, the oil liquid can be supplied into the fuel tank of the vehicle using a refueling nozzle attached to the weighing machine 6 in a refueling amount according to the customer's request.

  On the other hand, when a crew member of a tank lorry vehicle performs unloading work, etc., at night after the gas station closes, the crew member remotely operates a radio equipped in advance in the cab of the vehicle. A wireless signal can be transmitted while in a car.

  At this time, a radio signal can be received through the antenna 47 by the control device 46 provided on the head case 42 side, and the electric motor 43 of the rope drive device 41 can be driven and controlled by remote operation. Thus, the winding and unwinding operation of the guard rope 39 by the rotating drum 44 can be remotely controlled, and the guard rope 39 together with the sliders 19 and 20 in the fixed struts 12 and 13 can be selectively set to the above-described raised position and lowered position. Can be moved to.

  Therefore, the crew of the tank truck can remotely operate the rope drive device 41 of the guard device 11 while being in the driver's cab. For example, the tank truck can be moved to the refueling station with the guard rope 39 moved to the lowered position. You can bring it into the premises 1 and get in.

  And the crew of the tank truck can carry out the single unloading work in the site 1 with a sufficient margin, and after the single unloading work is finished, the tank truck is carried out from the site 1 of the gas station, By remotely operating the wireless device again, the rope drive device 41 of the guard device 11 can be automatically operated in a state where the vehicle is mounted on the tank truck.

  As a result, the guard rope 39 can be moved together with the sliders 19 and 20 in the fixed columns 12 and 13 to the above-described raised position, and the troublesome work of stretching the crime prevention chain as in the prior art can be eliminated. Further, illegal entry of the vehicle into the gas station after closing can be prevented well by holding the guard rope 39 in the raised position, and the crime prevention and security of the gas station can be improved.

  When the gas station is closed, the intermediate movable strut 31 is raised upward from the position of the drainage groove 7, and the guard rope 39 is stretched between the fixed struts 12 and 13 and the movable strut 31 with sufficient tension in this state. It is possible to prevent loosening of the guard rope 39 by laying it around (that is, placing the guard rope 39 in the raised position), and the vehicle illegally enters the site 1 of the gas station. Can be prevented well.

  Therefore, according to the present embodiment, the guard rope 39 can be selectively moved between the ascending position and the descending position together with the sliders 19 and 20 in the fixed struts 12 and 13. The intermediate movable strut 31 provided on can be selectively raised and lowered (tilted) between the standing position and the tilting position.

  Thereby, the single unloading work etc. which are performed after a gas station closes, for example can be smoothed, and a worker's burden etc. can be reduced significantly. And the safety | security at the time of such an independent unloading work can be ensured favorably, and the whole workability | operativity can be improved reliably.

  Further, when the gas station is opened, the guard rope 39 is lowered downward together with the sliders 19 and 20 in the fixed struts 12 and 13, and the movable strut 31 is tilted into the drainage groove 7 to be movable. The support column 31 and the guard rope 39 can be stored in the drain grooves 7 and 8 located on the boundary side in the site 1 of the gas station, and the movable column 31 and the guard rope 39 enter and exit the gas station. This can prevent the vehicle from getting in the way.

  In particular, the guard device 11 according to the present embodiment includes an intermediate movable column 31 provided in the middle of the drainage groove 7 at a position near the corner portion 9 among the drainage grooves 7 and 8 extending along the boundary of the site 1. Since it is configured to be able to be stored in the drainage groove 7 (including the corner portion 9), for example, when a gas station is opened, a vehicle driven by a customer smoothly passes through the vicinity of the corner portion 9 and enters the site 1 You can go in and out.

  Moreover, since the movable support | pillar 31 is formed using the hollow cylinder with which both ends became the open ends 31A and 31B, for example, when the washing water etc. which generate | occur | produce in a gas station flow in into the drainage ditch 7 In addition, these waste water can be smoothly discharged along the drain grooves 7 and 8 while being circulated in the movable column 31.

  Thereby, the business activity at the time of opening of a gas station can be performed smoothly without delay. In addition, the troublesome work of attaching and removing crime prevention chains, etc. as described in the prior art can be abolished, and a place for special storage of these chains can be eliminated, and space for the gas station can be saved. Etc. can be achieved.

  Moreover, in the present embodiment, the movable support 31 provided on the corner 9 side of the site 1 can be raised and lowered, so that the movable support 31 and the guard rope 39 together with the drainage groove 7 when the gas station is opened. , 8 (corner section 9), and can smoothly carry out sales activities when the gas station opens.

  Further, since the driven slider 20 provided in the driven fixed column 13 is formed with a larger weight than the driven slider 19 provided in the driven fixed column 12, the rope drive The guard rope 39 is slackened by the guard rope 39 between the safety pin 40 (rope fixing portion) on the side of the upper lid 17 and the pulley 26 of the slider 20 in the stationary support column 13 on the driven side when the guard rope 39 is wound and unwound by the device 41. And the like can be suppressed by the weight of the slider 20 due to the additional weight 30 or the like.

  The driven slider 20 is provided with a backup roller 28 that prevents the slider 20 from tilting in the fixed column 13 together with the rollers 24 on the guide surface 13C side. Even when it becomes smaller and slack is likely to occur, it is possible to prevent the slider 20 from being inclined in the driven fixed column 13, and the slider 20 extends along the guide surfaces 13 </ b> C and 13 </ b> D of the fixed column 13. Smooth movement up and down can be compensated.
