Therefore, in the counting unit 6, in the former order, if the count is in the positive direction, for example, addition, and in the latter order, if it is counted in the opposite direction, for example, by subtraction, the count value in this counting unit 6 is is proportional to the distance from an arbitrary reference position, so the amount of elevation of the device 3 and the position of the device 3 in the liquefied gas tank 1 can be measured based on this count value. Note that even in a case where the device 3 oscillates when going up or down, and the same detection unit 5 detects the same detection target 4 multiple times, the counting unit 6 can detect alternate detections from the respective detection units 5. Since the configuration is such that signals are counted forward or backward depending on the detection order, overcounting does not occur.

得ることは勿論である。In this mechanism, when the valve 11 is closed, the heating means 14 is operated to vaporize the liquefied gas in the storage chamber 10, thereby causing the liquefied gas to flow out from the communication portion 13 and increasing the buoyancy. In addition, when the heating means 14 is not in operation, the valve 11 is opened to discharge vaporized gas from the communication portion 12, thereby reducing the buoyancy, and by adjusting the buoyancy in this way, the equipment 3 can be raised or lowered. It is something that makes you As described above, this elevating mechanism can independently raise and lower the equipment 3 without the need for an elevating cable and its hoisting device, so it has the advantage of not requiring a large-scale device as an elevating mechanism. As described above, the present invention has a configuration in which the device is moved up and down along three guide cables installed vertically inside a liquefied gas tank, etc., and a plurality of detection targets configured on each guide cable. , the configuration is such that detection is performed by a detection unit provided on the equipment side, and these detection positions are spaced apart in the vertical direction of the equipment so that they alternate in a circulation manner, and the detection is performed alternately from each detection unit. A counting section that counts the signals forward or backward according to the detection order is provided to measure the amount of elevation of the device, so it requires a position measurement cable, a winding device for this cable, and a winding device for the cable. Compared to conventional devices that include a counting section that is linked to the picking operation, this device has the advantage of reducing costs and requiring less effort. In addition, in the present invention, if a mechanism that can be independently raised and lowered without a lifting cable and its hoisting device is applied as a lifting mechanism for one device per year, only the control cable can be configured between the device and the upper part of the liquefied gas tank. It will get better if you do it, power 1
In this configuration, the above-mentioned effects can be further enhanced, and the sealing performance of the upper part of the liquefied gas tank can be improved. As mentioned above, the present invention
It goes without saying that the present invention can be applied to lifting equipment in liquefied gas tanks, as well as lifting equipment in devices other than liquefied gas tanks.
