Description

[Detailed Description of the Invention] This invention relates to a device for checking the attachment and detachment of a hook when lifting a cylinder gate main body (hereinafter referred to as the gate main body) in a cylinder gate.

The main body of the gate installed inside the water intake tower has multiple sliding pipes of different diameters slidably fitted together, and the height is adjusted by the sliding of each sliding pipe, allowing surface water near the water surface to flow from the water intake at the top end. It takes water and flows it to the downstream pipe leading to the lower end.

When carrying out maintenance and inspections such as bottom water intake, repainting, and other such maintenance on such cylinder gates, it is necessary to fully retract the gate body, roll it up, and return it to its original position when the work is completed.

In the above work, to fully retract the cylinder gate body that is in the water intake state, loosen the hoisting device that lifts the sliding tube at the top end of the gate body, and lower the sliding tube at the top end by its own weight. The next sliding tube also descends, and all the sliding tubes overlap to become fully contracted.

In order to lift the gate body which is now fully contracted,
After the hook provided on the uppermost sliding cylinder is engaged with the outer engagement pin of the lowermost sliding cylinder, the lifting beam connected to the uppermost sliding cylinder must be lifted.

Furthermore, once repairs are completed, the hooks must be removed from the lowered gate body, but these hooks cannot be seen directly as they are attached and detached underwater.

Therefore, in the past, the hook was automatically engaged and disengaged by operating a hoist in the control room on the water intake tower and moving the top sliding tube up and down using a lifting beam, but this method does not work underwater. It was impossible to check the operation from the control room at the top of the water intake tower, which caused problems such as having to pull it up while hanging on one side.

In order to solve the above-mentioned problems, this invention provides an attachment/detachment confirmation device that uses an optical inspection device to confirm the engagement/disengagement status of a hook underwater from an operating room.

Embodiments of the device of this invention will be described in detail below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a dam constituting a reservoir. A water intake tower 2 made of a screen is provided inside this dam 1, and a cylinder gate main body A is provided within this water intake tower 2.

This gate body A is made by slidably fitting together a plurality of sliding tubes 3 with different diameters, and when the upper sliding tube 3 is pulled up, the protrusion on the outer periphery of the lower end of the upper sliding tube 3 changes to the lower sliding tube 3. It is designed to engage with a protrusion on the inner periphery of the upper end of the sliding tube 3 and pull it up.

A lifting beam 6 is fixed to the upper ends of a plurality of tension rods 5 which are slidably attached to the outer frame 12 of the water intake port 4 at the water intake port 4 formed at the upper end of the uppermost sliding tube 3.

This beam 6 is suspended by a wire rope 8 that is hoisted up by a hoist installed in an operation room 7 on the water intake tower 2, and between this beam 6 and the water intake 4 there is a float that moves up and down along a rod 5. 9 is provided.

Reference numeral 10 denotes a suspension stand installed in the water intake tower 2 so that it can rise and fall freely, and a repair cover 11 is detachably attached to this stand 10 by means such as bolting. This is used when blocking.

The upper end of a hook 13 is swingably attached to the lower part of the outer frame 12, and an engagement pin 14 that engages with the hook 13 is provided outside the upper part of the lowermost sliding tube 3.

The hook 13 has a structure in which a balance weight or a remote control wire is provided to automatically engage and disengage the hook 13 from the engagement pin 14 by lowering the uppermost sliding tube 3 to perform vertical movement. Alternatively, there is a structure in which the hook 13 is operated by a remote control wire to engage and disengage the engagement pin 14, but both are known.

B is a pair of optical inspection devices installed in the water intake tower 2.

That is, the eyepiece section 16 is provided at the upper end of the long tube 15, and the objective section 17 is provided at the lower end.

An eyepiece section 16 (includes an eyepiece lens and a diopter adjustment ring,
A relay lens is provided in the cylinder 15, and an objective lens, a prism 18, and an illumination lamp 19 are provided in the objective part 17.
Aim near 4.

In the illustrated example, the upper end of the tube 15 is passed through the floor plate 21 of the operation room 7 to position the eyepiece 16 inside the operation room 7, and the power cord 22 of the illumination lamp 19 is connected to the power distribution board inside the operation room 7. Connecting.

However, this is just an example. For example, if a pedestal for inspection is provided around the outer periphery of the lifting beam 6 and the structure is such that a worker can stand on this pedestal, the eyepiece 16 etc. In addition, if there is a stand or a workbench on which a worker can sit at an appropriate location within the water intake tower 2, an eyepiece 16 or the like may be provided there.

In the above embodiment, FIG. 1 shows the water intake.

At this time, the lifting beam 6 is pulled up by the rope 8, the gate body A is stretched, and the float 9 rises above the water surface, and surface water flows from between the float 9 and the water intake 4 to the water intake 4.
and flows into the downstream pipe line 23.

Next, in the case of fully retracting the gate body A, first loosen the wire rope 8 and lower the beam 6, then the sliding tubes 3 other than the lowest stage will descend, the gate body A will be fully retracted, and the beam 6 will be lowered. The hook 13 that has descended together with the upper sliding tube 3 engages with the outer engagement pin 14 of the lowermost sliding tube 3.

At this time, the switch in the operation chamber 7 is turned on, the illumination lamp 19 of the inspection device B is turned on to illuminate the vicinity of the engagement pin 14, and when looking through the eyepiece lens 16, the hook 1 relative to the engagement pin 14 is
You can check the engagement status of step 3, so after checking this,
When the rope 8 is wound up, the fully contracted gate body A is lifted up to its upper limit.

In this way, the gate main body A is hoisted up in a fully contracted state, and when maintenance and inspection etc. are completed, the rope 8 is loosened and the gate main body A is lowered in a fully contracted state, and the hook 13 is automatically disengaged from the engagement pin 14. At this time as well, after confirming that the hook 13 has come off the pin 14 using the inspection device B, the top sliding tube 3
When the gate body A is lifted, the gate body A becomes in an extended state.

As described above, this device is equipped with an inspection device B consisting of an optical system inside the water intake tower 2, so that the state of engagement and disengagement between the hook 13 and the engagement pin 14 of the sliding tube 3 that has descended into the water can be checked. Reliable engagement and disengagement can be achieved by performing the engagement and disengagement operations while watching.

Therefore, troubles such as hanging on one side can be prevented.
