Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a manual hydraulic control valve device used for various deck machines, fishing machines, aquaculture-related machines, etc., provided on ships such as fishing boats.

[0002]

[Prior art]

 For example, a deck machine such as a fishing net hoist installed on the deck of a fishing boat is generally driven by an actuator such as a hydraulic motor. The connection and disconnection of oil to this actuator is performed by a manual hydraulic control valve device.

In the conventional hydraulic control valve device, one end side of the control shaft provided with the switching means is provided so as to project from the case, and the operation lever is attached to the projecting portion of the control shaft. Therefore, the positional relationship between the operation lever and the supply / discharge ports (A, B: actuator side, P, T: hydraulic pump side) provided at two locations on both sides of the case is fixed.

Further, as shown in FIG. 4, the deck machinery of a fishing boat is installed in various places such as starboard, port, front and rear of the hull. The actuator is piped through the device. In this case, the positional relationship between the valve device and the actuator is limited by the arrangement of various devices and workers on the deck, and it is not always possible to arrange them in a suitable place. Furthermore, the operating lever of the valve device must be arranged facing the side of the vessel where it does not get in the way so that there is no risk of malfunction due to workers coming into contact with the deck work.

[0005]

[Problems to be solved by the present invention]

 Due to the above reasons, the conventional method using the valve device has the following problems. That is, since the conventional valve device has no directional freedom in installation, the supply / discharge port on the actuator side of the valve device and the supply / discharge port of the actuator may not be opposed to each other but may be located on the opposite side.

Further, in the series circuit, it is necessary to connect the supply / discharge port on the hydraulic pump side of the valve device and the supply / discharge port on the hydraulic pump side of another valve device, and there is a trade-off between these, so-called turning The number of pipes has increased and the entire pipe has become complicated. In addition, as the number of pipes to be turned increases, the total length of the pipes becomes longer, increasing the material cost and man-hours for the pipes, increasing the cost, and increasing the internal resistance to reduce the effective pressure. It also has an impact.

[0007]

[Constitution of device]

 Means of the present invention taken to solve the above problems are as follows. That is, the present invention includes a primary side flow passage connected to a hydraulic pump and a secondary side flow passage connected to an actuator, and the control handle is rotated by an operation handle to rotate the control shaft to the primary side flow passage and the secondary side flow passage. In a hydraulic control valve device for connecting to and disconnecting from a passage, both ends of a control shaft are projected from a case, and an operating handle is detachably attached to both projection parts.

[0008]

[Action]

 The control shaft of the hydraulic control valve device according to the present invention is a double shaft type, and the operation handle can be mounted on any side of both shafts. Therefore, when installing the hydraulic control valve device, it is not necessary to consider the position of the operation handle in advance, and the supply / discharge ports of the primary side flow path and the secondary side flow path are oriented in the direction convenient for the piping. It is possible to prioritize things, and it is possible to reduce waste of piping.

【Example】

 The present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a side view showing an embodiment of a hydraulic control valve device according to the present invention, and FIG. 2 is a front view. Reference numeral V denotes a hydraulic control valve device, which has a case 1. A control shaft 2 is pivotally supported on the case 1. The control shaft 2 is provided with mounting portions 21 and 22 with both ends protruding from the case 1 by a required length.

Inside the case 1, a primary side flow path (not shown) connected to the hydraulic pump and a secondary side flow path (not shown) connected to the actuator are provided. On one side surface (back side in FIG. 1) of the case 1, supply / discharge ports P and T corresponding to the primary side flow passages are provided. Regarding the supply / discharge ports P and T, the symbol P is the supply side and the symbol T is the discharge side. Further, on one side surface (front side in FIG. 1) of the case 1, supply / discharge ports A and B corresponding to the secondary side flow passages are provided.

An operation handle 3 is attached to the attachment portions 21 and 22 of the control shaft 2. The operation handle 3 is removable and can be attached to any side of the attachment portions 21 and 22. The hydraulic control valve device V turns the control shaft 2 with the operation handle 3 to connect and disconnect the primary side flow passage and the secondary side flow passage, that is, the supply / discharge ports P and A and the supply / discharge port T. B can be intermittent.

FIG. 3 is an explanatory view showing an example of piping using the hydraulic control valve device according to the present invention. The operation of this embodiment will be described with reference to FIGS. 1 to 3 and in comparison with FIG. In FIG. 4 showing a conventional example, there is no degree of freedom in the installation direction of the hydraulic control valve device, and it can be installed only in one direction such that the operation handle is on the side of the vessel. Therefore, as shown in FIG. 4, when a plurality of hoisting machines 4, which are deck machines, are installed on the starboard, port, front and rear portions of the deck, the location of the turning pipe (indicated by R) ) Are in seven places.

On the other hand, the control shaft 2 of the hydraulic control valve device V according to the present invention is a double shaft type, and the operation handle 3 is installed on the ship side of the mounting shafts 21 and 22 after the hydraulic control valve device V is installed. It can be installed on the side where Therefore, when installing the hydraulic control valve device V, it is not necessary to consider the position of the operation handle 3 in advance. For example, the supply / discharge ports A and B of the secondary side flow path of the hydraulic control valve device V should be set as much as possible. It is possible to give priority to the direction in which the pipe is convenient, such as by arranging the actuator 40 facing the actuator (hydraulic motor) 40 of the hoist 4.

This enables piping as shown in FIG. That is, there are two places of the turning pipe (indicated by reference symbol R) unlike the conventional one in which the hoisting machine 4, the hydraulic pump 5, and the tank 6 have the same arrangement, and the waste of the pipe is small. Has become. As described above, the hydraulic control valve device V according to the present invention has a large degree of directional freedom when it is installed, and the piping can be made efficient, and maintenance is easy.

[0015]

[Effect of device]

 The present invention has the above configuration and has the following effects. The control shaft of the hydraulic control valve device according to the present invention is a double shaft type, and the operating handle can be attached to the side that is the side of the vessel after the hydraulic control valve device is installed. Therefore, when installing the hydraulic pressure control valve device, it is not necessary to consider the position of the operation handle in advance.For example, the supply / discharge port of the secondary side flow path of the hydraulic control valve device should be connected to the actuator of the deck machine as much as possible. It is possible to give priority to directing the pipe in a direction convenient to the pipe, such as arranging the pipes facing each other.

[0016] With this, it is possible to reduce the number of turning pipes, and there are many problems in the conventional turning pipes, such as a large amount of waste of piping material, unnecessary work for piping work, and It is possible to eliminate the decrease in effective pressure due to the increase in internal resistance and the complexity of maintenance.
