Abstract

And more particularly, to a lifting device for a gas detection device capable of stably installing a gas detection device on a large storage tank.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to an elevating apparatus for a gas detecting apparatus, and more particularly, to an elevating apparatus for a gas detecting apparatus capable of stably installing a gas detecting apparatus on a large storage tank.

Generally, laser light of a specific wavelength is absorbed by arbitrary gas. The laser light receiving device using the characteristic of the laser light can detect the leakage of gas even at a long distance.

For example, there are two wavelengths of 3.3922 μm (λ 1) and 3.3912 μm (λ 2) in 3.39 μm of the laser beam irradiated by the He-Ne laser, λ 1 strongly absorbing to methane, Which is absorbed only a little.

A device for laser-based remote methane leakage detection using this feature is fixed at the top of a large gas storage tank, about 45 kg.

Normally, for the installation of gas detection equipment of about 45kg, temporary scaffolding or fixing iron structure should be installed. However, this method of operation involves transporting the equipment to the top of a large gas storage tank, and all subsequent work is done at the top, which implies human or material risk from falling.

In addition, provision of temporary scaffolding is limited to gusts or diaries due to the characteristics of the upper part of the storage tank, and steel structures may not be available depending on the design of the tank.

The abovementioned lift device is positioned at a desired height of the detection device 200 in accordance with the appearance of the rod 42 so as to detect gas detection.

5, the upper plate 20 has a cutout communicating with the through hole 21 from the edge thereof. The door 22 is connected to the hinge 23 to open and close the cutout, And the cylinder body 41 can be inserted between the bottom plate 10 and the top plate 20 through the cutout.

That is, the cylinder body 41 is moved from the side surface of the space between the bottom plate 10 and the top plate 20 into the cut-out portion where the door 22 is opened so that the upper end of the cylinder body 41 is inserted into the through- . In this case, the entire lifting cylinder 40 is lifted and the troublesome work of connecting the lifting cylinder 40 to the through hole 21 from the upper portion to the lower portion is solved.

4A and 4B, a support cap 80 having a plurality of legs 81 formed with a notch groove 82 is coupled to the lower end of the cylinder body 41, A support wall 11 on which the legs 81 are inserted and supported is formed so that the lower end of the cylinder body 41 can be stably supported.

Reference numeral 12 denotes an opening in which the hydraulic port 43 for providing the hydraulic pressure to the lift cylinder 40 is located.

3, 6 and 7, the fixing plate 50 is provided with a plurality of hooks 51. One end of the wire 300 is connected to the hook 51 and the other end is fixed to the ground And the wire 300 can be tensioned by the lever block 310.

The horizontal position of the detecting device 200 can be maintained by adjusting the tension of the wires 300.

7 and 8, a plurality of support pipes 400 are connected by a socket 410 between the upper plate 20 and the fixing plate 50, and the length of the rod 42 is increased To minimize the shaking.

Reference numeral 420 denotes a turnbuckle which finely adjusts the degree of inclination of the level sensor 72 according to the measurement to enable the horizontal installation of the gas detection device 200 through the height of the support pipe 400, As a wire block, the elevating cylinder 40 and the detecting equipment 200 are prevented from being suddenly conducted in one direction at the time of first ascending and descending.

3 and 9, each rod 42 is clamped by a clamp 900 at the boundary of each rod 42 so that each rod 42 that is actuated by air pressure moves in the direction of the non-compressible fluid So that the expansion and contraction to the lower part caused by the characteristics is prevented.

The lifting device of the present embodiment as described above first opens the door 22 of the upper plate 20 to support the lifting cylinder 40 by being coupled to the lower plate 10 and the upper plate 20. [

The tension of the wire 300 is adjusted to the lever block 310 according to the measured value of the level sensor 72 Thereby enabling the detecting apparatus 200 to maintain a horizontal state.

The supporting pipe 400 is connected to the upper plate 20 and the fixing plate 50 by the socket 410 and the rod 42 of the lifting cylinder 40 is connected to the detecting equipment 200 can be stably supported.

Meanwhile, when a strong wind such as a gust of wind is generated according to the measurement of the anemometer 71 during the ascending operation of the detecting device 200, the rising operation is stopped to prevent a safety accident.

The lift device described above makes it possible to reliably handle the heavy object handling in the restricted space above the storage tank 100.

In addition, physical damage due to a fall that may occur in the process of transferring the expensive detecting equipment 200 to the upper part is eliminated.

In addition, since there is no electrical device in the lifting cylinder 40, the ignition source which induces fire or explosion is completely removed and the explosion-proof structure to be applied to the combustible gas facility is basically excluded, thereby securing the reliability of the device.

Further, since the lifting cylinder 40 is made of a lightweight aluminum material, it is not necessary to install the lifting cylinder 40 for each storage tank 100, which is very economical.
