Description

  The present invention is used in a hydraulic cylinder drive device used to control a sluice installed in a dam or river, and prevents secondary disasters caused by inability to control during an emergency such as a power failure due to an earthquake disaster or equipment failure. The present invention relates to an emergency hydraulic apparatus for urgently operating a hydraulic cylinder in order to operate the emergency cylinder and an emergency drive apparatus using the emergency hydraulic apparatus.

  The water resources stored at the sluices in dams and rivers are extremely versatile and indispensable for social life. Furthermore, in order to properly use the water resources stored in this dam or river, a control facility (flooding gate or drainage facility) that adjusts the amount of water is necessary.

  Many of the spillway gates and water-use discharge facilities, which are control facilities for adjusting the amount of water, mainly use a drive circuit using pressure oil as a drive source. Since this hydraulic drive circuit obtains the hydraulic power source with the power of the electric motor, if there is a power failure due to an earthquake, etc., the hydraulic power source will be lost, so there is concern about the occurrence of secondary disasters due to the inability to control the equipment. ing.

  Conventionally, a device disclosed in Patent Document 1 shown in FIG. 8 has been known as an emergency hydraulic device used in the event of a power failure due to an earthquake disaster or a power failure.

  The apparatus of Patent Document 1 has a configuration in which a discharge side is connected to a hydraulic cylinder 70 and includes a reversible variable displacement hydraulic pump 60 driven by an engine E, a tank 60a, and pilot check valves 61a and 61b.

  The supply and discharge of the working pressure oil to and from the hydraulic cylinder 70 by the apparatus having the above configuration is performed by switching according to the rotation direction of the reversible variable displacement hydraulic pump 60. Pilot check valves 61a and 61b provided between the hydraulic cylinder 70 and the pump 60 prevent the hydraulic cylinder 70 from lowering when the supply / discharge is switched.

JP 10-281106 A

  As shown in FIG. 8, the reversible variable displacement hydraulic pump 60 driven by the engine has a hydraulic cylinder generating function according to the function of generating hydraulic pressure and the rotational direction of the hydraulic pump 60. Since both of the control functions for controlling the operation direction are used, the rotation direction of the engine is changed to change the operation direction of the hydraulic cylinder 70, and the rotation speed is changed to change the operation speed of the hydraulic cylinder 70. Since it is necessary to change the number, the operability is poor and it is difficult to respond in an emergency.

  It is an object of the present invention to improve the operability and cope with an emergency by separating a hydraulic pressure source having a function of generating hydraulic pressure and a control function for controlling the supply direction of pressure oil from the hydraulic pressure source. To do.

An emergency hydraulic apparatus according to the present invention is a portable emergency hydraulic apparatus that supplies and discharges hydraulic pressure oil in place of the hydraulic unit to a hydraulic cylinder to which hydraulic pressure oil is supplied and discharged by a hydraulic unit. and emergency hydraulic power source constituted by a hydraulic pump with a fuel supply circuit connected to the driven tank in, whereas the discharge circuit connected to the oil supply circuit and the tank connected to the discharge side of the emergency hydraulic power source on the side is connected to the other side It has a direction switching valve for connecting a supply / discharge circuit connected to a hydraulic cylinder, and an emergency supply / discharge circuit having a hydraulic cylinder joint connected to the supply / discharge circuit and connected to the hydraulic cylinder.

  The emergency hydraulic apparatus according to the present invention has an effect of improving operability because a hydraulic pressure generating function by a hydraulic power source and a control function for controlling supply and discharge of pressure oil from the hydraulic power source are provided separately. Furthermore, it has the effect that the emergency hydraulic device can be reduced in size and weight by using the tank of another device.

  The emergency drive device of the present invention is connected to an emergency hydraulic power source constituted by a hydraulic pump provided with an oil supply circuit that is driven by a power source and connected to a tank, and a supply circuit in which the discharge side of the hydraulic power source is connected to one side. A direction switching valve for connecting a discharge circuit connected to a hydraulic cylinder on the other side, and an emergency supply / discharge circuit having a hydraulic cylinder joint connected to the hydraulic cylinder and connected to the supply / discharge circuit. An emergency hydraulic device having a hydraulic cylinder, a hydraulic pressure pump driven by a power source and a tank, and a directional control valve connected to a normal supply / discharge circuit for supplying and discharging hydraulic pressure oil discharged from the hydraulic pump to and from the hydraulic cylinder A normal drive device configured with a stop valve that opens and closes the normal supply / discharge circuit in the normal supply / discharge circuit, and is provided between the stop valve and the hydraulic cylinder. The multifunctional valve which includes a port having a self-closing function is provided, characterized in that to connect the hydraulic cylinder joint of the emergency supply and discharge circuit to the port having the self-closing feature.

  The emergency drive device of the present invention has an effect of improving operability because the hydraulic pressure generating function by the hydraulic pump and the control function for controlling the supply and discharge of the pressure oil from the hydraulic source are provided separately. Furthermore, since the tank of other equipment can be used for the oil supply circuit connected to the hydraulic pump and the discharge circuit connected to the direction switching valve, it is not necessary to provide a tank in the emergency hydraulic system, so the emergency hydraulic system can be reduced in size and weight. It has the effect. In addition, since the emergency hydraulic device can be configured to be small and light, there is an effect that the emergency hydraulic device can be installed in a normal drive device that requires a fixed arrangement or a portable type in a normal drive device having an existing hydraulic unit.

Therefore, the flexible hose in the present invention is a general term for all of the flexible hose and the fixed pipe constituting the emergency supply / discharge circuit.

Hydraulic unit The hydraulic unit 42 is a hydraulic source device of a normal drive device that supplies hydraulic pressure oil to the hydraulic cylinder 31 at normal times, and its main configuration is connected to the tank 47 and the tank 47 to generate hydraulic pressure oil. The hydraulic pump 45 and a control valve body 51 for controlling the operating pressure oil discharged from the hydraulic pump 45 are configured. The discharge side of the hydraulic pump 45 is connected from the normal supply / discharge circuits 48a and 48b via the triple multifunction valve 35. The hydraulic pressure oil is supplied to the hydraulic cylinder 31.

  The housing 11 for housing the hydraulic unit 42 has a structure in which a hydraulic pump 45 and a control valve body 51 are housed and installed in an upper housing 11b, and a lower housing 11a constituting a tank 47 is installed below the housing. .

Detailed description of each component Next, each component part and attachment part which comprise the emergency drive device 20 are described.

Emergency Hydraulic Device An emergency hydraulic device 43 shown in FIG. 1B includes a control valve body 50 having a direction switching valve 24 and an emergency hydraulic power source 12 having a power-operated hydraulic pump 22. The oil supply circuit 46 b of the operation type hydraulic pump 22 and the tip end portion of the discharge circuit 46 a on one side (hydraulic unit 42 side) of the direction switching valve 24 are submerged and connected to the inside of the tank 47 via the connector 56. There is also a case. Residual pressure maintaining valves 46e and 46f at the front end portions prevent a mixture of air by leaving a low pressure in the discharge circuit 46a and the oil supply circuit 46b.

  The other side (hydraulic cylinder 31 side) of the direction switching valve 24 is connected to the hydraulic cylinder 31 via supply / discharge circuits 26 and 27 and flexible hoses 26b and 27b connected to the supply / discharge circuits 26 and 27. It is.

Similarly, the joint 38b is a joint with an automatic closing function, and the hydraulic cylinder joint 17b of the flexible hose 27b is attached and detached.

  The closing of the first stop valve 35c and the second stop valve 35d of the triple-type multi-function valve 35 closes the normal supply / discharge circuits 48a and 48b, and the hydraulic unit 42 and the hydraulic cylinder 31 are disconnected. The emergency hydraulic device 43 and the hydraulic cylinder 31 are connected by the flexible hoses 26b and 27b. As described above, the triple multi-function valve 35 has a function of switching and connecting the hydraulic cylinder 31 from the hydraulic unit 42 to the emergency hydraulic device 43 by the operation thereof.

  Further, the third stop valve 35h shuts off the normal supply / discharge circuits 48a and 48b by shutting off the hydraulic cylinder 31 and the hydraulic unit 42 by the first stop valve 35c and the second stop valve 35d and opening this. I can do it. The continuous multi-function valve 35 is the applicant's Japanese Patent No. 3696850 and will not be described in detail.

Characteristics and comparison of the second and third emergency drive devices The second and third emergency drive devices have a structure in which a stationary emergency hydraulic device 55a is permanently installed along the housing 11, so that it can be applied to existing facilities. There are many parts to be improved, and as with newly installed equipment, equipment with an emergency drive device is obtained. Accordingly, an emergency drive device can be configured very easily in the event of a power failure due to an earthquake or the like, and an emergency response can be made by simply operating the emergency hydraulic device.

  Furthermore, since the second and third emergency drive devices are always installed and can be configured very easily, they can be operated as necessary and trained in preparation for a disaster, so that the operation of the device is well known and smooth when a disaster occurs. Correspondence becomes possible.

  The second emergency drive device 105 is highly safe because it supplies and discharges the discharge hydraulic oil of the stationary emergency hydraulic device 55a directly to the hydraulic cylinder 31, but the installation location of the casing 11 and the hydraulic cylinder 31 is separated. Inconvenient in case.
