Description

[Detailed description of the invention]

[0010]

[Industrial applications]

 The present invention relates to a heating pipe made of steel pipe provided on a tank top of a cargo hold for transporting a solidifying liquid cargo requiring heating.

[0020]

[Prior art]

 As shown in FIGS. 3 and 4, the prior art is provided with several systems of heating pipes 33 at a constant height on a tank top 32 of several cargo holds 31 provided in a cargo area, First, the solidifying liquid cargo is prevented from solidifying to maintain the liquid state.

The heating tube uses steam or heat medium oil as a heating medium, and the length or area of the heating tube is determined by the conditions such as the temperature rise time and holding and the outside air temperature, so that the heating tube can be efficiently heated. ing.

The heating pipe 33 is piped at a fixed distance (120 to 150 mm) from the tank top 32, and its support is generally made of steel or stainless steel equilateral angle iron. A pad 34 is welded to the top 32, and a column 35 is erected on the pad 32.The column 35 is provided at least at both ends, and a column 35 is provided as necessary at the intermediate portion, and the column 35 at one end is connected to the other. A mount 36 crossed the end support 35, and an equilateral angle steel was provided in an inverted L-shape.

The gantry 36 is provided with bolt holes at regular intervals, and a heating tube 33 is screwed by a U-band and a nut 37 to form a solid structure.

[0060]

[Problems to be solved by the invention]

 The cargo holds of such cargo carriers often change their cargo, and the cargo holds are frequently cleaned. In particular, after unloading solidified liquid cargo, even if it is washed with a tank cleaning machine (hot water jet), the cargo remains on the tank top and the back of the gantry, leaving the place to be left to human labor. As described in the technology, the heating tube, the gantry, the support, and the like are firmly provided between a few hundred mm from the tank top, and there is a problem that it takes time to clean a narrow place.

In the construction process of a ship, welding of a joint of a heating pipe, welding of a pad, welding of a column, and welding of a gantry are also included. The structure of a cargo hold, so-called tank top and wall, is made of stainless steel or epoxy. The special coating was applied, and it took a lot of trouble to cure and repair the tank top.

The present invention has been made in view of such insufficient points of the conventional technology, and the purpose is to clean the gantry to a blind spot by the cleaning by the tank cleaning machine in the first step. In order to avoid this, the base is provided in the shape of an L-shaped equilateral angle iron, and the heating pipe is hooked downward, thereby facilitating cleaning.Furthermore, the heating pipe is divided into fixed sections and turned upside down. This facilitates cleaning of the tank top.

In addition, since the heating pipe is manufactured by dividing the heating pipe into fixed sections, it is intended to reduce the fire work (welding) on the tank top.

[0100]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention divides the heating pipe of the tank top into fixed sections to form a heating pipe unit, and the heating pipe unit is attached to the heating pipe with a horizontal gantry, One end of the gantry is pivotally attached to the hinge at the tip of the fulcrum post, a flexible pipe is provided at the joint where the heating pipe near it joins the heating pipe main pipe, and the other end is supported by an upper support and a lower support, The heating tube unit is moved up and down.

The heating tube is supported by several pedestals, and the pedestal uses an equilateral angle steel in an L shape, and the heating tube is hooked on its lower surface with U bolts and nuts to constitute a heating tube unit. Things.

[0120]

[Embodiment of the invention]

 This invention divides the heating tube of the tank top into fixed sections to form a heating tube unit, and attempts to bring the heating tube unit up and down. One end of the heating tube unit is hinged. A flexible pipe is provided at the joint where the heating pipe in the vicinity is connected to the main pipe of the heating pipe.

Further, the heating tube is supported by several stands, and the stand uses an equilateral angle steel in an L shape, and the heating tube is hooked on its lower surface with U bolts and nuts to constitute a heating tube unit. doing.

[0140]

【Example】

 The embodiment will be described with reference to the drawings. As shown in FIGS. 1 and 2, a certain height is maintained on a tank top 2 of several cargo holds 1 provided in a cargo area from a deck. There are provided several systems of heating pipe main pipes 10 which are piped, and the heating pipe main pipe 10 of the system is branched into several units, and a heating pipe unit 11 is provided.

In the heating tube unit 11, the heating tube 3 is hoofed on a horizontal pedestal 6, one end of the pedestal 6 is axially attached to a hinge 5 at the tip of a fulcrum support 7, and the other end is connected to an upper support 12 and a lower support. The support 13 supports the support.

The heating tube 3 is made of an equilateral angle steel made of steel or stainless steel used for the gantry 6 in an L-shape, holes are made in the gantry 6 at regular intervals, and U bolts and nuts are formed on the lower surface of the gantry 6. Wear a hoof.

The base of the fulcrum support 7 welds the pad 4 to the tank top 2, and the tip forms a hinge 5. The base of the lower support 13 at the other end of the gantry 6 is welded to the tank top 2, The column 12 is welded to the gantry 6 and is detachable from a bolt / nut 14 at an intermediate portion.

The heating tube 3 is connected to the heating tube main tube 10 on the hinge 5 side, and its joint uses a flexible tube 8 that is flexible against twisting. It is adapted to follow the rotation about the center.

The cargo hold 1 is cleaned every time the cargo is changed. However, when the preload is a solidifying liquid, etc., the cargo hold 1 is washed from the middle high position of the cargo hold by several tank cleaning machines (hot water jets). However, cargo remains in the dead tank top 2 such as the heating tube 3. In order to clean the remaining cargo, the heating tube unit 11 is rotated around the hinge 5 so that the heating tube unit 11 is set up as shown in FIG. 1, and the cleaning and manual cleaning are performed. Thus, the cleaning work is simplified.

[0200] Also, in the manufacturing process, the so-called fire work at the tank top is only the mounting of the pad 4 of the fulcrum support 7 and the mounting of the pad 4 of the lower support 13, and the manufacture of the heating tube unit 11 main body is as follows. It can be manufactured and transported on land.

[0210]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. In this invention, the base is provided in the shape of an L-shape of equilateral angle iron, and the heating tube is hooked downward, thereby facilitating cleaning. In addition, the heating tube is divided into fixed sections and turned upside down. This facilitates cleaning of the tank top. In addition, since the heating pipe is divided into fixed sections and manufactured, the aim is to reduce the amount of fire work (welding) on the tank top.
