Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing gate device for restricting vehicle traffic. More specifically, the present invention relates to a swivel type in which a traffic restricting member is driven to rotate two-position between a position where a vehicle such as an automobile is blocked and a position where it is not blocked. The present invention relates to an open / close gate device.
[0002]
[Prior art]
As this type of swing-type open / close gate device that is driven to swing, there are known, for example, a hinge / swing gate provided at a common entrance of a house, company, factory, or other specific facility.
These hinge / swing gates have a gate body, which is a traffic regulating member, supported by left and right gate pillars via a hinge portion having a turning center axis, and a driving means for turning the gate body is configured so that the gate body is moved by a rotation lever. It is configured by a link mechanism that turns around a turning center axis.
The hinge / swing gate is locked / unlocked by a brake attached to the drive motor, and the user does not need to lock / unlock manually.
[0003]
[Problems to be solved by the invention]
By the way, in an open / close gate device for restricting vehicle traffic installed on a general road or the like, a member made of a steel pipe or a solid rigid body having sufficient rigidity against a vehicle collision is used as a traffic regulation member. The entire load of the large and long passage restriction member cannot be supported by the swing hinge provided on the support column, and a support rod is provided separately for suspending the tip portion connected to the support column. Things are common.
As described above, in the conventional swing-operated opening / closing gate device, the support mechanism and the drive mechanism have a complicated structure as the passage restriction member to be turned has a heavy structure, and the degree of freedom in design is narrowed. It was very difficult to avoid the cost increase.
[0004]
In addition, in the open / close gate device for restricting vehicle traffic, not only the rigidity of the traffic regulating member itself is necessary, but also the strength for maintaining the posture of the closed position, that is, the durability of the locking means is important. In the case where the traffic restriction member is easily opened due to a vehicle collision, there is a risk that an excessive impact load will act on the drive mechanism and it will be destroyed. It is common to fix in a closed position.
[0005]
However, the canniki stick with impact resistance is naturally heavy, and there is almost no traffic regulation member further equipped with a mechanism for driving and controlling it. The ones that are manually mounted, and the one that manually connects the cannula rod between the opposing traffic control members have been mainstream.
[0006]
The present invention has been made in view of the present situation, and is capable of driving and controlling a kanuki member having impact resistance while avoiding an increase in cost, and can easily and stably maintain the closed position of the passage restricting member. It is intended to provide a gate device.
[0007]
[Means for Solving the Problems]
As a result of diligent investigation to solve the above-mentioned problems, the present inventor has a relatively simple structure and a very small size by configuring the passage restriction member using a steel pipe that can be slidably mounted on the kanuki member. The present inventors have found that the cannula member can be easily driven and controlled by the driving force, and have completed the present invention.
[0008]
That is, the present invention provides a passage restriction member that has rigidity against a vehicle collision and that can block the passage of a vehicle such as an automobile at a closed position that extends along the width direction of the vehicle, and a closed position that blocks the passage of the vehicle. Retreating from the vehicle passage space, supporting means for supporting the two-position turning operation between the open position that does not block the vehicle passage, driving means for driving to turn the passage restriction member, A drive control means for electrically controlling a drive means, and selectively controlling the passage restricting member at the closed position and the open position; and a locking means for fixing the passage restricting member at the closed position; An opening / closing gate device for restricting vehicle traffic, wherein the traffic control member includes a main steel pipe extending horizontally along a longitudinal direction, and the front end opening of the main steel pipe is used as the locking means during locking.

[0009]
In such an open / close gate device, in the closed position where the passage restricting member extends horizontally in the passage width direction, the cannula member is similarly horizontally installed inside the main steel pipe constituting the passage restricting member. Because a heavy kanuki member can be easily slid with a small driving force in the direction, the complicated and expensive drive mechanism and slide guide required to move the kanuki member up and down to fit in the locking hole on the passage surface. A mechanism or the like is not necessary, and an increase in cost can be avoided, and the closed position of the passage restricting member is easily and stably maintained.
[0010]
Here, in the closed position extending along the passage width direction from both sides sandwiching the passage, a pair of passage restriction members in which the main steel pipes are arranged in a straight line are provided, and one passage is used as the locking means. The kanuki member is slidably provided on the main steel pipe of the restricting member, and the main steel pipe of the other passage restricting member is allowed to function as a fitting receiving portion that receives the protruding portion of the cannulated member in the locked position from the tip opening thereof, In the state where the protrusion of the cannula member is inserted into the other main steel pipe, the fitting receiving part that receives the protrusion of the cannuki member in addition to the passage restriction member, in which each passage restriction member is fixed at the closed position There is no need to provide a special structure on the passage, which is very reasonable.
[0011]
As a drive means for slidingly driving the cannula member, a drive shaft that is rotationally driven by a drive motor is provided on the main steel pipe, and both ends of the drive chain engaged on the drive shaft are respectively along the longitudinal direction of the cannuki member. It is preferable that the cannuki member is fixed to a predetermined place and the cannula member is slid and driven together with the drive chain. In particular, an end fixing bracket is provided at a predetermined part of the cannula member to which the end of the drive chain is fixed. More preferably, a sliding member that slides in the sliding direction with respect to the inner surface of the main steel pipe while supporting the kanuki member is provided on both sides of the bracket where the fixed portion of the drive chain is sandwiched.
[0012]
Further, as drive control means for the kanuki member, limit switches for detecting the locking position and the unlocking position of the kanuki member are respectively projected at predetermined positions on the inner surface side of the main steel pipe, and the bracket for fixing the end portion is provided. Each of which is provided with a pressing surface to switch on by pressing the corresponding limit switch as the cannula member slides, so that it is easy and low-cost due to mechanical detection. Is done.
[0013]
Further, manual unlocking means for manually moving the cannula member at the lock position to the unlocking position irrespective of the driving means is provided, and the manual unlocking means is configured to open the tip end of the main steel pipe at the time of locking. A cannula part that partially protrudes from the front part is divided into a front member provided on the front end side and a rear member provided with a drive part, and a slide guide hole is formed in the front member along the longitudinal direction. A fixing pin that is configured to be elastically connected to the kanuki member by inserting the rear member into the insertion member, and is inserted into an insertion hole that is continuously drilled in the front member and the rear member, so that the connecting portion is fixed in a non-expandable manner. In addition, it is preferable that each of the front members is detachably provided with an operation handle for sliding the front member backward in a state where the fixing pin is removed.
[0014]
According to such manual unlocking means, usually, a fixing pin is attached to an insertion hole continuously drilled in the front member and the rear member, and the connecting portion is fixed so as not to expand and contract. By fixing the operation handle on the front member from which the fixing pin has been removed, the front member can be slid backward by manual operation, and the cannula part can be moved from the locked position to the unlocked position. Can be opened manually.
[0015]
As a support means for supporting the passage restricting member, a cylindrical or columnar column having rigidity against vehicle collision and having a sliding guide portion formed along the outer peripheral surface thereof is erected on the side of the passage, and On the base end side of the passage restricting member, a cylindrical fitting body is provided that is fitted on the support column and includes a sliding portion corresponding to the sliding guide portion on the inner peripheral side thereof. In the case where the entire load is supported by the support column via the cylindrical fitting body and is horizontally swiveled around the axis centering on the entire support column as a sliding shaft, the total load of the passage restriction member including the cylindrical fitting body is It is sufficient to have a driving ability that is fully supported by the support so that it can be swiveled horizontally, and that has a minimum driving force against natural wind speed load. A relatively free mechanism can be adopted. At the same time, this means that the traffic regulation member with the heavy weight of the kanuki member is turned horizontally and semi-permanently accurately and stably. There is no problem that it cannot be inserted into the vehicle, and the impact at the time of the vehicle collision is reliably received by the cannula part.
[0016]
As drive means for horizontally driving the passage restriction member, a drive wheel and a drive motor are configured as a unit, and this is attached to the tip of the passage restriction member so as to be slidable up and down via a guide means. Is preferred. According to such an open / close gate device, there is no drive mechanism around the column, the degree of freedom of the surrounding space is greatly improved, and the drive unit is always in contact with the road surface due to its own weight. Even if the road surface is fluctuating or inclined, such as an unpaved road surface, the road regulating member that automatically follows the road surface and horizontally turns around the support column is reliably turned.
[0017]

[0031]
As shown in FIG. 7, the supporting means 3 for supporting the passage restricting member 2 is a cylinder or columnar shape having rigidity against vehicle collision and having a sliding guide portion 61 formed along the outer periphery thereof. A column 60 is erected on the side of the passage. The support column 60 includes a base portion 60a embedded and fixed in the foundation concrete below the ground, and a support portion 60b vertically standing on the ground, and the tubular fitting body 20 of the passage restriction member 2 is externally fitted. The support portion 60b has a strong structure made of a cylindrical steel pipe having an outer diameter of 90 mm to 150 mm, or a solid cylindrical rigid body, and has a sufficient support strength and vehicle collision that can stably support the passage restriction member 2. Each passage restriction member 2 is supported by the column 60 via the cylindrical fitting body 20, and the entire center of the column 60 is used as a sliding axis. Is turned horizontally.
[0032]
More specifically, a spherical sliding guide portion 62 that supports the cylindrical fitting body 20 so as to be slidable in a free direction is formed on the upper portion of the support column 60, and the sliding formed along the outer periphery. The entire load of the heavy traffic regulating member 2 is supported by the support column 60 so as to be able to turn in a cantilever manner only through the guide portion 61, and is supported by the slide guide portion 61 and the spherical slide guide portion 62. Compared with other support structures in which the cylindrical fitting body 20 is supported so as to be free to behave and restrains the behavior, it is possible to prevent excessive load caused by excessive twisting, etc. Unreasonable abnormal load is not generated in the sliding guide part or the bearing part, and stable operation is performed for a long time. Therefore, the traffic regulation member 2 having a large-diameter kanuki member 30 made of a steel pipe or a solid rigid body having an outer diameter of 70 mm to 115 mm and a length of about 600 mm to 1200 mm is semipermanently accurately and stably horizontal. The problem that the cannula part cannot be inserted into the fitting receiving part due to distortion caused by long-term use does not occur, and the cannula part reliably receives the impact at the time of the vehicle collision.

It is supported by the inner wall 26 so as to be able to turn horizontally through a spherical sliding guide 62 and sliding guides 61 and 61, respectively. The sliding guide portion 61 includes a cylindrical sliding member formed using, for example, a polyamide-based MC nylon material, an ultrahigh molecular weight polyethylene material, an alloy of brass or aluminum, and the like on the outer peripheral surface of the support portion 60b. It is fitted to the middle position in the vertical direction and the lower end position near the ground. Further, the upper portion of the cylindrical fitting body 20 provided with the spherical sliding bearing 25 is closed by a hemispherical cover lid 27.
[0034]
As described above, in the open / close gate device 1 of the present invention, the entire load of the passage restricting member 2 including the cylindrical fitting body 20 is fully supported by the column 60 so as to be horizontally rotatable, and the driving ability to drive the rotation is as follows. Since it can be turned easily if it has the minimum necessary driving force for the natural wind speed load, a very simple and relatively free mechanism can be adopted as the driving means 7. In the form, as shown in FIGS. 8 and 9, the drive wheel 71 and the drive motor 72 are configured as a unit, and are attached to the tip of the passage restricting member 2 so as to be slidable up and down via the guide means 8. By doing so, the driving means 7 is configured, and no driving mechanism is required around the support column, and the degree of freedom of the surrounding space can be greatly improved.
[0035]
Specifically, as shown in FIG. 9, a drive unit 70 is configured by fixing the drive wheel 71 and the drive motor 72 to a mounting base 73, and the mounting base 73 is connected via a sliding member 74. The drive unit 70 is attached to the passage restricting member 2 so as to be vertically slidable by supporting the rectangular guide surface 80a and the guide grooves 80b and 80b inside the bracket 80 so as to be slidable vertically. Accordingly, the drive unit 70 is always grounded to the road surface by its own weight, and can automatically follow the road surface even on a road surface with a slight height fluctuation or an inclination, such as an unpaved road. The passage restricting member 2 that rotates horizontally as an axis can be reliably driven to rotate. The guide groove 80b is formed over the upper end of the bracket 80, and the entire drive unit 70 can be easily removed and replaced by attaching and detaching an end cap 81 attached to the upper end.
[0036]
The drive motor 71 uses a brake mechanism and a motor with a brake release lever, and is configured to release the brake mechanism and manually open and close the passage restriction member in the event of an emergency such as a power failure. ing. Further, the mounting base 73 is provided with a protective cover 75 that protects the drive wheels 71 and the drive motor 72 from rain and snowfall.
[0037]
Further, as means for detecting the closed position and the open position of the passage restricting member 2 in order to control the driving means 7, a switch is provided at a position where the passage restricting member should be stopped, or an abnormal current rise occurs when pressing is stopped. Various forms are possible, such as those that detect.
[0038]
【The invention's effect】
As described above, according to the opening / closing gate device for restricting vehicle traffic according to the present invention, in the closed position where the traffic restricting member extends horizontally in the passage width direction, the main steel pipe constituting the passage restricting member is provided inside the main steel pipe. Since the cannuki member is also installed horizontally, the heavy cannula member can be easily slid with a small horizontal driving force, and the cannuki member can be moved up and down to fit in the locking hole on the passage surface. In this case, a complicated and expensive drive mechanism or slide guide mechanism that is required in this case is not necessary, and an increase in cost can be avoided, and the closed position of the passage restricting member can be easily and stably maintained.
[0039]
In addition, a pair of passage restricting members in which the main steel pipes are arranged in a straight line are provided at closed positions extending along the passage width direction from both sides across the passage, and one passage restriction is provided as the locking means. The kanuki member is slidably provided on the main steel pipe of the member, and the main steel pipe of the other passage restricting member is functioned as a fitting receiving portion that receives the protruding portion of the kanuki member in the locked position from the distal end opening thereof, In the state where the protruding part of the cannula member is inserted into the other main steel pipe, each passage restriction member is fixed in the closed position, so that a special structure for receiving the protrusion part of the cannuki member other than the passage restriction member is provided. There is no need to provide it separately on the passage, which is very reasonable.
[0040]
Further, as drive control means for the cannula member, limit switches for detecting the locking position and the unlocking position of the cannula member are respectively projected at predetermined positions on the inner surface side of the main steel pipe, and each of the end fixing brackets In addition, since a pressing surface for pressing the corresponding limit switch to switch it on is provided along with the sliding movement of the kanuki member, there is no malfunction due to mechanical detection, and the drive control means is simple and low-cost. realizable.
[0041]
In addition, the cannula member is divided into a front member having a cannula part protruding partly from the front end opening of the main steel pipe at the time of locking, and a rear member having a drive part, and the front member has a longitudinal direction. By forming a slide guide hole along the direction and inserting a rear member into the slide guide hole, a connecting portion that can be expanded and contracted with the cannula member is formed, and is inserted into an insertion hole continuously drilled in the front member and the rear member. In addition, a fixing pin for fixing the connecting portion so as not to be stretchable and an operation handle for sliding the front member to the rear in a state where the fixing pin is removed are detachably attached to the front member. In the event of an emergency, the front member can be manually slid backward using the operation handle, and the cannula portion can be moved from the locked position to the unlocked position. It can be opened a location manually.
[0042]

While the entire load is supported by the column via the cylindrical fitting body, the entire column is horizontally swiveled around the axis centered on the slide axis, the driving ability to rotate the passage restricting member is natural wind speed load. Can be easily turned, and a very simple and relatively free mechanism can be adopted as the driving means. At the same time, this means that the traffic regulation member with a heavy weight of the kanuki member is turned horizontally and semipermanently accurately and stably. The problem that it cannot be inserted into the part does not occur, and the impact at the time of the vehicle collision can be reliably received by the cannula part.
[0043]
As drive means for horizontally turning the passage restricting member, a drive wheel and a drive motor are configured as a unit, and this is attached to the tip of the passage restricting member so as to be slidable up and down via the guide means. There is no drive mechanism in the surroundings, and the degree of freedom of the surrounding space can be greatly improved, and the drive unit is always in contact with the road surface due to its own weight. Even on an unpaved road or the like, the road regulating member that automatically follows the road surface and horizontally turns around the support column as a central axis can be reliably driven to turn.
