Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an enclosure opening / closing device for a ground or the like, which is provided with a lifting fence that allows a work vehicle and a racehorse to pass through on a part of the fence on a competition ground such as a racetrack. It is a thing.

[0002]

[Prior art]

 Conventionally, when putting a work vehicle, a racehorse, etc. inside the ground fence of this kind of stadium, it is common to move or open a removable part of the fence. .

[0003]

[Problems to be solved by the device]

 With conventional fences, when each type of work vehicle, racehorse, etc. passes, the worker manually moves some of the fences to form a passage, which makes the work difficult. It is troublesome and time-consuming. The present invention solves such troublesome and complicated work, and its purpose is to easily raise and lower a part of the fence of a stadium or the like by a simple construction operation to make the work vehicle easy. It is intended to provide a device for opening and closing a fence enclosure that opens and closes a ground that forms a passageway through which people can pass.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention equips a part of a fixed enclosure (2) of a gland body (1) of various shapes with an elevating elevator (3). The elevating fence (3) is provided with extensible columns (7) at the lower ends of both ends. Several elevating cylinders (8) and (8) are fitted in the expandable column (7). In addition, the water supply / drainage hose (11) is connected to the lower end of the telescopic column (7), and the water supply / drainage pump (9) is connected to the water supply / drainage hose (11) so that the elevating fence (3) can be moved up and down to a predetermined position. It is what

[0005]

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. A ground main body (1) of various shapes such as a stadium, a racetrack and the like has its entire outer periphery partly moved up and down with a fixed fence (2). It is composed of an elevating fence (3). The fixed enclosure (2) is supported by fixed columns (5) (5) ... Standing at predetermined intervals. The elevating fence (3) provided in a part of the fixed enclosure (2) is erected and supported by telescopic columns (7) and (7) at the bottom of both ends of the baffle. Next, the elastic columnar bodies (7) and (7) are formed by fitting a plurality of large and small elastically elevating and lowering tubular bodies (8) (8). The ascending / descending cylinder body (8) at the uppermost portion of the telescopic column bodies (7) (7) is fixed to the lower surface of the elevating fence (3). Further, lower ends of the telescopic columns (7) and (7) are fixed to a foundation table (15) of the ground (16), and a water supply / drainage hose (11) is connected to a part of the lower ends. The water supply / drainage hose (11) is connected to a unit of a water supply / drainage pump (9) that moves by supplying and discharging tap water or the like. The water supply / drainage pump (9) is equipped with an antenna (10) for remote operation. Further, as shown in FIG. 4, the lifting fence (3) is provided with a horizontal balance plate (14) on the upper part thereof, and inside the gland body (1), a safety frame (12) against impact and a ground body are provided. The balance weights (13) are provided on the outside of (1). Further, as shown in FIG. 5, the fixed enclosure (2) is also provided with a balance plate (14) for synthetic resin on the upper part thereof, and the balance plate (14) has a safety plate inside the ground body (1). A frame (12) is provided, and a weight (13) for balancing is provided outside the gland body (1).

[0006]

[Action]

 The present invention is configured as described above, and its usage will be explained. When a work vehicle or a racehorse passes through the ground, both sides of the lift fence (3) provided in a part of the ground body (1) are provided. The elevating cylinders (8) and (8) of the expansion and contraction column (7) provided in the are sequentially raised by the water pressure by the operation of the water supply / drainage hose (11) from the water supply / drainage pump (9) by the push button or remote control switch. The lifting fence (3) is pushed up to a predetermined height to form a passage for work vehicles and the like. When the elevating fence (3) is to be closed down, it is lowered by a push button or the reversing operation of the remote control switch to restore the normal state.

[0007]

[Effect of device]

 As described above, according to the fence raising / lowering opening / closing device of the present invention, it is very easy to operate, and it is a troublesome work to remove and open a part of the fence, which is difficult to open and close. This has the effect of solving the drawback of labor and time. In addition, it is possible to reliably prevent entry into the ground more easily than a part of the fence, and it is also very safe because the fence can be formed without change when running a racehorse. Also, by installing an expansion / contraction column consisting of several elevating cylinders under both ends of the elevating fence, the elevating fence is firmly supported by the expandable column when it contracts, and it can be used stably. There is a convenient effect that the required height can be sufficiently secured by increasing or decreasing the number of cylinders. Also, with the water supply / drainage hose and water supply / drainage pump connected to the lower end of the extension / contraction column, the effect of being able to move the elevating fence up and down very easily and reliably, and the length of the water supply / drainage hose There is a convenient effect that water pumps can be freely installed at various locations.
