Description

This invention can be used as an opening/closing gate for a tide embankment to prevent storm surges, a water gate for an embankment to prevent river flooding, or an entrance for a surrounding wall (water barrier) installed to protect a divided area from flood damage. The present invention relates to a horizontally pulling gate that opens and closes a gate, and has a structure in which the door is opened and closed by horizontally pulling it against a fixed wall.

Side-sliding gates installed at the openings of seawalls and river confluences can be opened and closed quickly and safely in response to emergencies such as tsunamis caused by earthquakes, high waves caused by typhoons, and sudden rises in water at night. Required to close.
However, opening and closing the door is generally performed manually, which takes time and effort, and may not be able to respond to emergencies or may be dangerous. In particular, with regard to tsunamis, the time between the occurrence of an earthquake and its arrival is short, resulting in the loss of many precious lives during the Great East Japan Earthquake as they were working to close gates.

In order to automate the opening/closing work of this opening/closing door, in conventional horizontal opening/closing gates, for example, a drive rack gear is installed on the top surface of the gate body in the direction of movement thereof, and a drive rack gear is mounted on the embankment body (fixed wall-shaped part). A horizontal pulling gate (lateral pulling opening/closing gate) is disclosed that is provided with a gear motor (electric motor) that rotationally drives a pinion gear (see Patent Document 1). In this case, a gate (opening/closing door) is opened and closed by the driving force of a gear motor (electric motor) that is fixed to a fixed wall portion and driven by power supplied from the outside. Note that in a device that directly utilizes the driving force of the electric motor, a large electric motor is required, which tends to result in a large-scale configuration. Since the electric motor requires external power, it will not be able to be driven if the external power supply fails in the event of a large-scale disaster.

On the other hand, the present applicant has previously developed a horizontally-swinging gate that opens and closes the horizontally-swinging door against a fixed wall-shaped part, which includes a movable body fixed to the movable door and a movable body. A linear guide for the movable body fixed to a fixed wall part that guides the movement of the moving body, a fixed rack fixed to the fixed wall part, a cylinder device fixed to the opening/closing door, and a cylinder extending from the tip of the cylinder rod. A movable rack fixed to the movable rack, a movable rack linear guide that guides the movement of the movable rack, a starting pinion that is held by the movable body and meshes with the movable rack, and a driven pinion that interlocks with the movable rack and meshes with the fixed rack. By equipping the system with a power transmission mechanism that transmits driving force to speed up the extension operation of the cylinder device, a small electric motor can automate the opening and closing operations of horizontally pulling doors. We have proposed a horizontally pulling opening/closing gate (see Patent Document 2) that is now possible and can be installed rationally.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best embodiment of the horizontal pulling gate according to the present invention will be described in detail based on the accompanying drawings (FIGS. 1 to 4).
This horizontally pulling opening and closing gate has a structure in which the opening and closing door 20 is opened and closed by horizontally pulling against the fixed wall portion 10.

Reference numeral 15 denotes a rack and pinion mechanism, which is constituted by a rack 21 fixed to the opening/closing door 20 and a pinion gear 16 rotatably held by the fixed wall portion 10 and meshed with the rack 21, and serves as a power transmission mechanism. . In addition, in this embodiment, the rack 21 is extended and fixed to the upper surface of the opening/closing door 20 in the longitudinal direction thereof.

A deceleration drive mechanism 30 is connected to the pinion gear 16 and configured to drive the rack and pinion mechanism 15.
This deceleration drive mechanism 30 is connected to an electric motor 31, a hydraulic pump 32 that outputs (outflows) required water pressure using the power of the electric motor 31, and a pinion gear 16, and the output from the hydraulic pump 32 is connected to the hydraulic piping 34. The hydraulic motor 33 outputs rotational power reduced in speed to the pinion gear 16 by water pressure supplied through the hydraulic motor 33 .
Note that as the hydraulic motor 33, one manufactured by RIBEX Co., Ltd. (83, Shichijo Goshonouchi Minami-cho, Shimogyo-ku, Kyoto City) can be used.

According to this, the driving force of the electric motor 31 can be decelerated via the hydraulic pump 32 and further can be decelerated via the hydraulic motor 33. For example, the rotation speed of the electric motor 31 of 1800 rotations per minute can be converted into the output of the hydraulic motor 33 of 60 rotations per minute, which is reduced to one-thirtieth, for example. Therefore, the pressing force required to open and close the opening/closing door 20 can be appropriately obtained by the small electric motor 31. That is, in this embodiment, sufficient water pressure necessary for driving the opening/closing door 20 to open/close can be obtained even with a small electric motor of, for example, 24V. Note that the opening/closing work of the opening/closing door 20 performed by the driving force of the water pressure does not need to be fast, and the opening/closing of the opening/closing door 20 is not repeated in a short period of time. There is no problem with a configuration that provides sufficient deceleration.

Further, according to this embodiment, the electric motor 31 is driven by the electric power of the storage battery 51 stored by the solar cell 40, and is provided so as to be operated by remote control. That is, the water pressure pump 32 and the water pressure motor 33 are provided to be driven by the electric motor 31, and the power source of the electric motor 31 is the storage battery 51 that is charged with the solar cell 40. Therefore, it does not require an external power source, and has a self-sufficient configuration with respect to the power source, and can operate independently even when the external power source is lost in a disaster.

On the other hand, a device that directly uses the power of the electric motor 31 as disclosed in Patent Document 1 generally requires an external power source of 200V for power, and requires a large-scale configuration. If the external power supply fails during a large-scale disaster, it will not be possible to operate the device.

The hydraulic motor 33 is held by the fixed wall portion 10. Further, in this embodiment, the pinion gear 16 and the hydraulic motor 33 are held in a lowered form by a cantilever beam 12 that cantilevers out from the upper surface portion 11 of the fixed wall portion 10.

According to the present invention, the water pressure motor 33 can be configured as a reduction gear in a small and lightweight manner, so that it can be more rationally arranged while being properly held on the fixed wall portion 10, compared to a reduction gear using gears. can do. Further, according to the present invention, the configuration is not complicated compared to the case where a cylinder device as disclosed in Patent Document 1 is used, and the simple configuration is suitable for the fixed wall portion 10. It can be arranged more rationally by keeping it in the same position.
Furthermore, in detail in this embodiment, the hydraulic motor 33 is held on the free end side of the cantilever beam 12, so that it is located on the opposite side with the pinion gear 16 in between with respect to the plane position of the fixed wall portion 10. It is held in a flat position, and the pinion gear 16 and the output shaft of the hydraulic motor 33 are connected in series. According to this, the configuration is easy to accommodate retrofit specifications. Note that the present invention is not limited to this form; for example, if the water pressure motor 33 is embedded in the fixed wall part 10 side, the water pressure motor 33 can be connected to the pinion gear 16 from the fixed wall part 10 side. Of course you can.

Further, according to this embodiment, the electric motor 31, the hydraulic pump 32, the solar cell 40, and the storage battery 51 are installed at a higher position than the rack and pinion mechanism 15 and the hydraulic motor 33.
In this way, the electric motor 31, water pressure pump 32, solar battery 40, and storage battery 51 can be installed at a high place by installing the water pressure motor 33 that drives the rack and pinion mechanism 15 and the water pressure pump 32 operated by the electric motor 31. , because it can be connected via hydraulic piping 34. That is, by being able to connect with the hydraulic piping 34, the degree of freedom in the installation position of the hydraulic pump 32, the electric motor 31 for operating the hydraulic pump 32, the solar cell 40, and the storage battery 51 can be increased. be. Note that a resin pipe can be used as the hydraulic pipe 34.

According to this, even in the event of a disaster in which the rack and pinion mechanism 15 and the hydraulic motor 33 are submerged in water, the electric motor 31, the hydraulic pump 32, the solar battery 40, and the storage battery 51 are located at a high place, so they will not be submerged in water. can be avoided. Therefore, it is possible to increase the possibility of proper operation even in such an emergency. In addition, even if the rack and pinion mechanism 15 and the hydraulic motor 33 are submerged in water, they have a highly water-resistant configuration. In particular, the hydraulic motor 33 operates using water as a medium, so there is a high possibility that its function can be maintained. . In addition, since it does not use oil like a hydraulic system, there is no need to worry about oil leaking and contaminating the water or the environment even if it is submerged in water.

Furthermore, the pinion gear 16 of this embodiment is provided so that a manual handle can be connected thereto. That is, the configuration is such that a manual handle can be connected with the hydraulic motor 33 being attached and detached. In this embodiment, the pinion gear 16 and the hydraulic motor 33 are connected in series by a connecting member 17 (see FIG. 1). According to this, on the contrary, the structure allows the deceleration drive mechanism 30 including the water pressure motor 33 according to this embodiment as a component to be suitably placed in an existing horizontal opening/closing gate configured to be connected to a manual handle. There is. Therefore, according to this, there is an advantage that the automatic opening/closing mechanism of the horizontal pulling opening/closing gate according to the present invention can be configured by retrofitting. In addition, in order to increase the deceleration rate of the drive of the electric motor 31, it is also possible to interpose a speed reducer constituted by gears between the pinion gear 16 and the hydraulic motor 33.

Further, 35 is a switching valve, which is controlled by a control device 52 arranged as shown in FIG. 2 so that it can be opened and closed as appropriate in order to switch the direction of water pressure from the water pressure pump 32 to the water pressure motor 33. It can be provided so that According to the control of the switching valve 35, the rotation direction of the hydraulic motor 33 can be switched, so that the opening/closing operation of the opening/closing door 20 can be switched by the switching. Note that this switching valve 35 can be constituted by a solenoid valve.
By the way, the switching of the rotation direction of the water pressure motor 33 is not limited to this, but may also be performed by controlling the control device 52 to switch the rotation direction of the electric motor 31 using an electric servo motor that can rotate in both forward and reverse directions, for example. It is possible. Further, since the electric motor 31 is an electric servo motor, its rotation speed can be controlled, and thereby the opening/closing speed of the opening/closing door 20 can also be controlled. In this case, 35 may be provided as a port (pipe connection).

That is, according to this, when water pressure is output/supplied from the water pressure pump 32 to the water pressure motor 33 via one of the water pressure pipes 34, the water pressure is applied so as to rotate the pinion gear 16 so that the opening/closing door 20 is closed. The motor 33 can be driven. On the other hand, when water pressure is output/supplied from the water pressure pump 32 to the water pressure motor 33 via the other water pressure piping 34, the water pressure motor 33 is rotated so as to reversely rotate the pinion gear 16 so that the opening/closing door 20 opens. It can be driven.

Further, the water pressure motor 33 of this embodiment acts as a relief valve using a predetermined water pressure, and can control the maximum pressure that acts when the opening/closing door 20 closes. Therefore, even if someone gets caught when the opening/closing door 20 closes, the pressure (pressure applied to the opening/closing door due to water pressure) is released, and pressure above a certain level can be avoided. This can improve the safety of side-pull gates.
Of course, the water pressure motor 33 may be operated using water mixed with antifreeze as a medium to prevent freezing, thereby improving the reliability of the horizontal opening/closing gate in winter. .

Further, in this embodiment, as shown in FIG. 2, the opening/closing operation of the opening/closing door 20 is remotely controlled via a control device 52 disposed in a control panel 50 by wireless or the Internet 60. It is set in. 55 is a wireless remote control device. Further, in this embodiment, 53 is a communication device unit, which is added to the control device 52 and provided. A remote control device 70 is connected to the communication device unit 53 via the Internet 60.

According to this, the automated opening/closing operation of the opening/closing door 20 can be suitably performed by remote control. Therefore, the operator does not have to perform any work at the site where the horizontal opening/closing gate is installed, and can quickly and safely open/close the opening/closing door 20.

Furthermore, in this embodiment, a motor having the same configuration as the above-described hydraulic motor 33 can be used as the above-described hydraulic pump 32 by arranging its input and output in opposite directions. According to this, the deceleration drive mechanism 30 can be configured compactly without becoming complicated, and a higher appropriate deceleration rate can be suitably obtained.

In addition, as shown in FIGS. 3 and 4, 18 is a warning/indicator light, which is arranged so as to improve safety by emitting light and displaying a warning during the opening/closing operation of the opening/closing door 20. ing. Of course, a sound generator can also be provided to issue a warning to improve safety.

Further, as shown in FIG. 2, a pressure gauge 36 is connected to each of the water pressure pipes 34, 34 on both sides, and is provided so as to be able to detect the water pressure applied to the water pressure motor 33 and display the information. It is being

In addition, in this embodiment, emergency situation detection means such as a seismograph 56 and a water level gauge 57 that detect an emergency situation and output detection information of the emergency situation, and the detection information is inputted from the emergency situation detection means and the emergency situation is detected. The configuration includes a control device 52 that controls the operation of the deceleration drive mechanism 30 so that the opening/closing door 20 is closed when it is determined that a situation has occurred.

That is, as shown in FIG. 2, the seismograph 56 and the water level gauge 57 are means for detecting an emergency situation, and are connected to the control device 52 located in the control panel 50 by wire or wirelessly (including the Internet network and mobile phone line). If an abnormality (emergency situation) is detected, the detection information can be output. In this embodiment, the control device 52 to which the detection information from the emergency situation detection means is input, if the detection information exceeds the reference value and determines that there is an emergency situation, the control device 52 controls the deceleration drive mechanism. 30 is automatically operated to control the opening/closing door 20 to close.

According to this, for example, the gate serving as the entrance to the flood wall can be quickly closed and damage caused by flood can be prevented, including when an unexpected disaster occurs, for example, at night or on a holiday. Note that the water level gauge 57 used here is not limited to those installed in rivers or gutters near the horizontal opening/closing gate according to the present invention, and is not limited to those installed in rivers or gutters near the horizontal opening/closing gate of the present invention. It also includes those that are observed by the controller 52 and whose detection information can be obtained by the control device 52.

Although the present invention has been variously explained above using preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is about.
