Description

  The present invention relates to a home safety fence, and more particularly to a home safety fence suitable as a simple safety fence having a vertically movable bar structure.

  As a conventional lifting safety fence installed on a station platform (station platform) to prevent falling, one using a rope (Patent Document 1, etc.) or one using a lateral bridge member (patent) Document 2 etc.) exists. In recent years, in this type of elevating safety fence, an example in which a bar-shaped member having a relatively light weight has been proposed as an example of a laterally extending member. Such a safety fence using an elevating bar-shaped door is effective in terms of simplifying the structure and reducing the weight, but has a weak point in terms of strength. In particular, the elevating bar-shaped door has a characteristic that it is not strong against lateral loads. Therefore, the enhancement is required. In order to increase the strength of the elevating bar-shaped door against the lateral load, it is desirable to provide a locking mechanism for fixing that increases the strength. On the other hand, in recent years, there is generally a locking device disclosed in Patent Documents 3 and 4 as a locking device for a lifting device.

  DESCRIPTION OF EMBODIMENTS Preferred embodiments (examples) of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the platform safety fence 10 according to the present embodiment basically enters the station platform 11 along the edge 11 </ b> A along the track of the station platform 11 (also referred to as “home”). The required number of units (number of units) will be installed according to the length of the train that stops. In FIG. 1, for convenience of explanation, one (one unit) home safety fence 10 is shown. The length of the home safety fence 10 in the lateral direction preferably corresponds to the length of one train of the vehicle. One home safety fence 10 constituting a unit is composed of a bar-shaped door 12 and support columns 13A and 13B arranged on both sides thereof and supporting the bar-shaped door 12. The two struts 13A and 13B are fixed to the home floor 11B. The bar-shaped door 12 is, for example, at least two bar members 14 and 15 that are horizontally spanned between the two support columns 13A and 13B and arranged at the upper and lower positions, and these two bar members 14 and 15. Each of these members is preferably composed of a rod-like (rod-like) mechanism member 16 which is disposed substantially at the center and is provided so as to be able to connect or engage between the two bar members 14 and 15. The two bar members 14 and 15 are moved up and down at a predetermined timing by the lifting device 18 provided inside each support column 13A and 13B while maintaining the vertical positional relationship (the interval changes). The operation is controlled to do. The operations of the elevating devices provided in the respective pillars 13A and 13B are synchronized, and the two bar members 14 and 15 perform the ascending operation or the descending operation while maintaining a horizontal state. When the two bar members 14 and 15 are lowered and are at the lowest position, the bar-shaped door 12 is closed and functions as a safety fence. When the two bar members 14 and 15 are raised and are in the uppermost position, the bar-shaped door 12 is in an open state. The bar-like mechanism member 16 is a member that relates the two bar members 14 and 15. When the bar-like door 12 is in the lowest position and closed, the bar-like mechanism member 16 is arranged in the lateral direction (in the bar member) of the two bar members 14 and 15 located above and below, as will be described later. It has the function of regulating the movement in the direction orthogonal to each other. This lateral movement is typically a movement that occurs when a load (force F1) applied from the platform side to the track side is applied to the bar-shaped door 12. The lower part of the bar-like mechanism member 16 is connected to the lower bar member 15, and an electromagnet device 17 for making a fixed state is attached to the lower end portion thereof. It is attached in a state of being inserted through a hole 14a formed in a direction. The electrical configuration for energizing the electromagnet device 17 is preferably provided using the internal space of each of the bar members 14 and 15 and the rod-like mechanism member 16.

  In the home safety fence 10 described above, the distance between the two support columns 13A and 13B is, for example, about 20 m. Accordingly, the two bar members 14 and 15 installed between the two support columns 13A and 13B have a length of at least 10 m. The bar-like mechanism member 16 provided on the bar-shaped door 12 of the home safety fence 10 is an auxiliary member for increasing the strength against the lateral load (force F1) of the two bar members 14, 15 constituting the bar-shaped door 12. Function as.

  Next, with reference to FIGS. 2-5, the operation | movement state of the home safety fence 10 and the characteristic structure for it are demonstrated.

  As shown by broken lines in FIGS. 2 and 4, an elevating device 18 is provided inside each of the columns 13 </ b> A and 13 </ b> B. Each lifting / lowering device 18 is configured by a mechanism for supporting and lifting the ends of the bar members 14 and 15 and a driving device for operating the mechanism. An arbitrary device configuration can be used as the lifting device 18. A specific configuration example of the lifting device 18 will be described later with reference to FIGS. 7 and 8. By this elevating device 18, the two bar members 14, 15 constituting the bar-shaped door 12 are moved up and down while maintaining a horizontal state, and further, the distance between the two bar members 14, 15 is changed according to the height. Go up and down. 2 and 3 show a state in which the bar-shaped door 12 is lowered to the lowest position, the bar-shaped door 12 is closed, and functions as a safety fence. A required interval is set between the two bar members 14 and 15 positioned above and below. This condition is created when the train is not on the home track, or when it comes in and tries to stop, or when it tries to leave. 4 and 5 show a state where the bar-shaped door 12 is raised to the uppermost position and the bar-shaped door 12 is opened. At this time, the two bar members 14 and 15 positioned above and below are set in a state of approaching or contacting each other. This state is created when the stop of the train is complete and the passenger door of the vehicle opens and the passenger is about to get on and off. After the bar-shaped door 12 is opened, the entry / exit door of each vehicle of the train is opened.

  With reference to FIG. 2 and FIG. 3, the configuration and operation in a state where the bar-shaped door 12 is lowered will be described. The two bar members 14 and 15 constituting the bar-shaped door 12 are moved to the lowest positions by the lifting and lowering devices 18 in the columns 13A and 13B, respectively, and are stationary at the positions. The heights of the two bar members 13 and 14 and the distance between them are necessary heights and distances that can restrict the behavior of passengers on the station platform 11 toward the track. As shown in FIG. 3 and the like, each of the bar members 14 and 15 has a rectangular cross-sectional shape, and has a width dimension through which the bar-like mechanism member 16 can be inserted. The bar members 14 and 15 may be pipe-shaped members or solid members. In FIG. 3, for convenience of illustration, the bar members 14 and 15 are shown in a solid (solid) sectional view for the sake of convenience. Any material such as a metal material or a high-strength resin material can be used. It is desirable to form a space for arranging electric cables and electric parts inside the bar members 14 and 15. The rod-like mechanism member 16 attached to the substantially central portion of the two bar members 14 and 15 is set so that the length thereof is longer than the interval between the two bar members 14 and 15. The lower part 16L of the rod-like mechanism member 16 is fixed to the lower bar member 15, and the upper part 16U is engaged so as to be inserted into a hole 14a formed in the upper bar member 14. The electromagnet device 17 described above is provided on the lower surface (lower end) of the lower portion 16L of the rod-like mechanism member 16. On the other hand, a plate (ferromagnetic magnetic plate) 19 such as an iron plate is embedded and fixed on the home floor 11B. The plate 19 is disposed corresponding to the position of the electromagnet device 17 and is attracted by electromagnetic force generated when the electromagnet device 17 is energized. In this case, the electromagnet device 17 attached to the lower end of the rod-like mechanism member 16 is an electromagnet that generates a magnet action when energized. The electromagnet device 17 is an electromagnet in a narrow sense, which is composed of an electromagnet (an electromagnet device in a narrow sense) that creates a fixed state and a plate (a ferromagnetic magnetic plate such as iron) in a broad sense.

  As described above, when the bar-shaped door 12 is lowered and arranged at the lowest position in the home safety fence 10, the bar-shaped door 12 serves as a safety protection fence that physically blocks the home side and the track side. Function. In this case, the electromagnet device 17 of the rod-shaped mechanism member 12 acts as a magnet when energized, attracts the plate 19, and the entire rod-shaped mechanism member 12 is fixed to the home floor 11B. Therefore, the rod-like mechanism member 12 is provided in a standing state fixed to the platform floor surface 11 </ b> B of the station platform 11. The lower bar member 15 is supported so as not to move because the central portion thereof is coupled and fixed to the rod-like mechanism member 16. Since the upper bar member 14 is in an engagement relationship in which the upper portion 16U of the rod-like mechanism member 16 is inserted into the hole 14a formed in the center portion, the load (force F1) in the D1 direction (lateral direction) shown in FIG. Etc.), the movement is restricted, and the strength against the lateral load is increased. FIG. 6 shows an enlarged view of the relationship between the upper bar member 14, the hole 14 a formed in the center thereof, and the upper portion 16 </ b> U of the rod-like mechanism member 16. In this way, the strength against the lateral load at the center of the two bar members 14 and 15 constituting the bar-shaped door 12 can be increased. Further, the two bar members 14 and 15 safely protect passengers on the station platform 11 as a bar-shaped door 12 of the home safety fence 10 from a train or the like entering the home track.

  In the above configuration, the operation for energizing the electromagnet device 17 is determined based on a control signal from the controller that controls the operation of the elevating device 18 that raises and lowers the bar-shaped door 12. That is, this controller outputs a control signal for energizing the electromagnet device 17 when the bar-shaped door 12 descends and reaches the lowest position. When the bar-shaped door 12 rises from the lowest position, the controller outputs a control signal for stopping energization of the electromagnet device 17. Further, a cable or the like (power feeding mechanism) for energizing the electromagnet device 17 provided at the lower end of the rod-like mechanism member 16 is usually wired using internal spaces such as the rod-like mechanism member 16 and the lower bar member 15. The

  With reference to FIG. 4 and FIG. 5, a structure and operation | movement of the state which the bar-shaped door 12 raised are demonstrated. The two bar members 14 and 15 constituting the bar-shaped door 12 are moved to the uppermost positions by the elevating devices 18 provided in the respective pillars 13A and 13B, and are still at the positions. At this time, the amount of movement of the lower bar member 15 is set larger than the amount of movement of the upper bar member 14, and finally the upper bar member 14 and the lower bar member 15 approach or contact each other. Arranged in a state. At this time, the distance between the lower bar member 15 and the home floor 11B is set to at least 2 m. When raising the bar-shaped door 12 at the lowest position, first, the energization to the electromagnet device 17 is stopped, and the fixed state of the bar-like mechanism member 16 on the home floor 11B is released. Thereafter, the two bar members 14 and 15 are raised so that the lower bar member 15 approaches the upper bar member 14. At this time, the upper portion of the bar-shaped mechanism member 16 moves through the hole 14 a of the upper bar member 14 so as to protrude above the bar member 14. Thus, the two bar members 14 and 15 are raised and the bar-shaped door 12 is opened.

  As described above, when the two bar members 14 and 15 of the home safety fence 10 are raised and the bar-like door 1 is opened, the door of each vehicle of the train stopped at the home 11 is opened, and passengers get on and off. . When the passenger situation is over, the door of each vehicle is closed, and then the bar-like door 12 is lowered to the state shown in FIG.

  In the configuration of the home safety fence 10 according to the above embodiment, the electromagnet device 17 provided at the lower end portion of the rod-like mechanism member 16 that functions as an auxiliary member that increases the load in the lateral direction is provided at the lower end portion of the rod-like mechanism member 16. It is also possible to provide the plate 19 and provide an electromagnet on the home floor 11B side. In this case, a configuration for energizing the electromagnet is provided on the home floor 11B side. In this case, the structure of the rod-shaped mechanism member 16 can be simplified and reduced in weight. Moreover, when providing the mechanism for electricity supply in the home floor surface 11B, it can provide easily. Furthermore, it can also comprise so that an electromagnet may be provided in both the lower end part of the rod-shaped mechanism member 16, and the home floor surface 11B. In the case of this configuration, the configuration is complicated, but the fixing force of the rod-like mechanism member 16 to the home floor 11B can be increased.

  Next, in the above embodiment, when the bar-shaped door 12 is lowered and fixed to the home floor 11B, the electromagnet device 17 is used. However, as this fixing means, in addition, a mechanical connection structure is used. You can also. As the mechanical connection structure, a well-known structure can be used.

  In addition, the relationship between the bar-shaped mechanism member 16 and the upper bar member 14 is not limited to the mounting relationship in which the rod-shaped mechanism member 16 is inserted, but a lock pin mechanism using, for example, a solenoid device is provided between them. When the position is reached, the lock pin mechanism is operated to connect the bar-shaped mechanism member 16 and the upper bar member 14 so that the bar-shaped mechanism member 16 is coupled and fixed to the upper bar member 14. it can.

  In the above embodiment, one bar-like mechanism member 16 is arranged in the vicinity of the central portion of the bar members 14 and 15, but the arrangement position of the bar-like mechanism members 16 can be arbitrarily changed, and the number of installation is also two. This can be done.
