Abstract

To quickly discharge dew condensation water in order to prolong a product life against the problem that a hydraulic head of a hydraulic machine for line connection, which is indispensable for power cable extension construction, is stored for a long period of time after the completion of the power cable extension construction, and if dew condensation occurs during the storage, dew condensation water is stagnated, leading to the start of corrosion, and if deep corrosion marks generate, a storage device becomes unusable.SOLUTION: A storage device is created that allows a hydraulic head to be stored in an upside-down position to make it easier to drain dew condensation water.SELECTED DRAWING: Figure 3

Description

[Technical Field]

[0001] The present invention relates to an inverted storage device for hydraulic heads of hydraulic machines for connecting electric wires. [Background technology]

[0002] The hydraulic heads of hydraulic machines for connecting electric wires are necessary for the construction of extension lines for power transmission lines, but once construction is completed, they are stored in a warehouse for a long period of time until the next extension work begins.

[0003] Condensation occurs due to the weather and climate during storage, and this condensation water accumulates inside the product.

[0004] If the hydraulic head is stored for a long period of time, the accumulated condensation water will corrode the cylinder inside the hydraulic head, causing pressure leaks and making it unusable for future construction work. Summary of the Invention [Problem to be solved by the invention]

[0005] The problem is that condensation water that forms in the cylinder cannot be discharged. The present invention has been devised to solve this problem. [Means for solving the problem]

[0006] Condensation occurs depending on the climate and weather, but it is important to prevent the condensed water from accumulating inside. Specifically, when storing, the hydraulic head should be stably inverted to allow the condensed water to drain by gravity.

[0007] To prevent the handle of the inverted hydraulic head for connecting electric wires from getting in the way, the machine has two side panels with large opening slits, which are welded to the bottom panel, which also has eyebolt holes for hanging. [Effects of the Invention]

[0008] Condensed water can be continuously discharged, preventing corrosion of the cylinder and extending the operating life of the hydraulic head. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is an isometric view of an inverted storage container for the hydraulic head of a hydraulic machine for connecting electric wires. [Figure 2] FIG. 1 is an isometric view of the hydraulic head of a hydraulic machine for connecting electrical installations. [Figure 3] This is a diagram showing the use of an inverted storage device for the hydraulic head of a hydraulic machine for connecting electric wires. The hydraulic head is stored upside down. DETAILED DESCRIPTION OF THE INVENTION

[0010] Condensation occurs on the hydraulic head of a hydraulic machine for connecting electrical wires due to the climate and weather during storage. If stored in the conventional upright position, the condensed water will remain inside the cylinder. The condensed water will corrode the inside of the cylinder. The corrosion marks resemble the marks of earthworms and are about 0.5 mm deep. This is caused by condensed water remaining for a long period of time. If you can drain the condensation quickly, you can prevent corrosion. For example, store the hydraulic head upside down so gravity can drain the condensation. To maintain the inverted position, the side panels are welded to the bottom plate with a curvature that encases the outer diameter of the seven cylinders and is tall enough to support them.

[0011] The present invention is configured as described above, and when in use, the hydraulic head of the hydraulic machine for connecting electric wires is turned upside down and inserted into the machine. Furthermore, if you need to store many heads in an aligned manner in a warehouse or similar, eyebolt holes for hanging are provided, making it easy to align and store them neatly.

Claims

[Claim 1] This product has a bottom plate (1) for supporting the hydraulic head of a hydraulic machine for electric wire connection in an inverted position, with the gate handle (which is difficult to turn upside down) as the fulcrum, two side plates (2) with a curvature that encases the entire cylinder section (7) of the compression head, and has an opening slit (3) to prevent the handles (6) protruding from both sides of the body from getting in the way when the machine is inverted.In addition, the bottom plate (1) has four eyebolt holes for easy organization when stored in an inverted position.This is the entire hydraulic head storage device for storing the hydraulic head of a hydraulic machine for electric wire connection in an inverted position.
