Description

[Detailed Description of the Invention] Industrial field of use [Technical Field] The present invention relates to an automatic slinging device for a corner drop member that can be inserted into and removed from a water channel.

2. Description of the Related Art Among the regular inspection work at facilities having a waterway communicating with the sea, such as a power plant, there is an important work for removing and cleaning marine organisms adhering to the pump room and water intake and discharge channels. When doing this work, it is first necessary to drain seawater for cleaning work. For this reason, as shown in FIG. 3, in the square groove 52 provided in the water discharge and discharge channel 51, the corner shaving material as a door body as shown in FIG. 4 (usually divided into a plurality of upper and lower parts). 53 was inserted to drain water from the pump room, intake and discharge channels, etc.
Therefore, every time the inspection work is performed,
It has to be inserted into and removed from the water discharge channel, and conventionally, the slinging work of the shavings 53 is performed by a diver.
It was done manually.

Problems to be Solved by the Invention According to the above-mentioned conventional manual work by a diver, there is a problem that the slinging work in water takes a long time and is accompanied by danger.

Then, this invention aims at providing the automatic slinging apparatus which can solve the said subject.

Means for Solving the Problems In order to solve the above problems, the automatic sling device of the present invention is
It is an automatic slinging device for a corner drop member that can be inserted into and removed from a water channel, and guide rollers that are rollable in the square grooves formed in the water channel are attached to both sides of the suspension beam so that the suspension beam can be positioned at a predetermined position. A guide concave portion into which the hanging piece on the corner drop member side can be inserted is provided, and an engaging pin which is retractable by a cylinder device is provided in a hanging hole of the hanging piece at a position corresponding to the guide concave portion; It is provided with a controller for remotely controlling the device.

Operation In the above configuration, when hoisting the corner drop member arranged in the water channel, first, the hoisting beam is hoisted by a crane or the like and inserted into the square groove via the guide roller. Next, the hanging beam is lowered to a position where the guide recess of the hoisting beam is completely accommodated, and the engagement pin is projected by the cylinder device. It is held safely and easily on the side of the hanging beam via.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, reference numeral 1 denotes a suspension beam for suspending the corner drop member 2, which is composed of a pair of left and right vertical members 3 and a horizontal member 4 connecting the vertical members 3 to each other. Guide rollers 5 that are rollable in square grooves formed in the water channel are attached to upper and lower positions on the outer side of each of the vertical members 3. In addition, guide recesses 1a into which the hanging pieces 6 of the corner drop members 2 can be inserted are provided at the right and left positions of the intermediate portion of the horizontal member 4, and a hanging hole 6a in the left-right direction is formed in this portion. Holding devices that can hold and release the corner drop member 2 via the pieces 6 are arranged. That is, inside the horizontal member 4, the pair of left and right side plates 11 forming the guide recesses 1a are provided with the engagement pins 12 slidably in the left-right direction, and the hydraulic cylinders that move the engagement pins 12 back and forth. (Cylinder device) 13
Are arranged. A proximity sensor (detector) 14 that detects the protruding state of the engagement pin 12 is arranged at a position opposite to the hydraulic cylinder 13. Then, the hydraulic unit of the hydraulic cylinder 13 includes a hanging metal fitting 16 for hanging the hanging beam 1 itself via a rope 15 such as a wire.
A controller 18 is provided which is located inside and remotely controls this hydraulic unit via a control signal cable 17.

That is, an accumulator 22 for supplying pressure oil is arranged in the tubular body 21 of the hanging metal fitting 16, and an electromagnetic opening / closing valve is provided in a valve box 23 provided at the bottom of the tubular body 21. 24 and an oil drain tank 25 are arranged. Of course, the solenoid on-off valve 24 and the hydraulic cylinder 13 are hydraulic hoses.
Connected by 26. A signal from the proximity sensor 14 is also input to the controller 18, and the engagement pin 12
You can see the entry and exit status of the.

A slinging operation of the corner drop material 2 in water in the above configuration will be described.

First, the suspension beam 1 is hoisted by the crane via the hoisting metal fitting 16 while the accumulator 22 stores the pressure oil. Next, the guide rollers 5 on both sides of the suspension beam 1 are inserted into the square grooves to lower the suspension beam 1 to a predetermined height. Then, the hanging piece 6 of the corner drop material 2 is the hanging beam 1.
When it is inserted into the guide recess 1a, the hydraulic cylinder 13 is actuated to move the engagement pin 12 into the hanging hole 6a as shown from the phantom line position (a) to the solid line position (b) in FIG. The corner drop material 2 is held by being projected. Of course, the holding state is confirmed by the signal of the proximity sensor 14. Then, when the holding is confirmed, the corner drop member 2 is lifted by the crane via the hanging beam 1. In this way, the plurality of corner drop members 2 may be sequentially lifted via the hanging beam 1.

Of course, this operation is performed by the controller 18 arranged on the ground side.

In addition, when slinging the shavings 2 on the ground, an operator places the hanging piece 6 of the shavings 2 in the guide recess 1a of the suspension beam 1.
Can be easily done by guiding.

In addition, since a plurality of corner drop materials 2 are vertically stacked,
Insertion recesses 2a into which the hanging pieces 6 can be inserted are provided at the bottom of the bottom of the bottom.

Further, the controller 18 has a built-in rechargeable battery, and a pressure detector for detecting the pressure in the accumulator 22 is also provided.

By the way, in the above embodiment, the controller 18 and the hydraulic unit side are connected via the control signal cable 17, but it goes without saying that the control may be performed by a wireless system.

As described above, according to the configuration of the present invention, the declining material arranged in the water channel can be automatically engaged with and held by the suspension beam via the suspension piece by the cylinder device. It is possible to perform slinging work safely and promptly as compared with the case where work is performed by a diver.
