Description

  The present invention relates to a tank container carried on a vehicle or a ship.

  According to Article 519 of the Industrial Safety and Health Regulations, it is obliged to provide an enclosure or handrail at the end of the work floor with a height of 2m or more where there is a risk of danger to the worker (worker) due to a crash. ing. And Paragraph 2 of the Article states that if it is difficult to provide an enclosure or a handrail on the work floor, measures must be taken to prevent the danger caused by a fall, such as by using a safety belt. ing.

  On the other hand, in a trailer loaded with a tank container, the tank is generally enlarged from the viewpoint of transport efficiency of liquid and powder, and a tank having a height exceeding 2 m is generally provided. Therefore, the worker, for example, climbs on the tank to take in and out liquid and powder from the manhole provided on the upper surface of the tank, and performs work at a high place on the scaffold provided on the tank. Become. In addition, because the vehicle height of trailers loaded with tank containers is limited to a predetermined height or less by the Vehicle Restriction Ordinance of the Ministry of Land, Infrastructure, Transport and Tourism, fences and handrails should be provided on the large tank scaffolds as described above. Is difficult. Under these circumstances, the worker on the tank works by attaching a safety belt hook to an appropriate structure of the tank (for example, the handle used for opening and closing the manhole). The occurrence of crashes is prevented.

  However, there may not be a structure where a safety band hook can be attached at an appropriate place. Even if an appropriate structure exists, the structure is not designed to withstand the load applied when the operator falls. For this reason, when an operator falls, the structure to which the safety belt hook is attached may be damaged, and the safety of the operator may not be sufficiently ensured.

In Patent Document 1, a traveling base that is movable, a support column that is provided on the upper surface of the traveling base and that is extendable in a height direction, and a bracket-like safety attached to an upper position of the support column. A safety band attaching device composed of a band attaching member or the like is disclosed. And this safety belt attaching device can be easily installed on the side of the vehicle when work is carried out on the transport vehicle, for example, and can secure the safety of the worker.

(3) A handle is provided on the column on the ladder side.

  The handrail provided in the tank container of the present invention is lowered when traveling the trailer loaded with the tank container, and raised when the trailer is stopped and work is performed on the scaffold on the tank. Can be made. For this reason, the tank container of the present invention has the problem that the handrail has the above vehicle height restriction even when the tank is enlarged within the range of the vehicle height restriction stipulated in the vehicle restriction ordinance from the viewpoint of transportation efficiency. It is useful because it does not cause any problems and can ensure a high level of safety when working on a scaffold.

  A tank container with a handrail of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing a configuration example of a tank container with a handrail according to the present invention. A tank container 10 with a handrail shown in FIG. 1 includes a tank 12 having an openable and closable manhole 11 that allows liquid or powder to be sent and received on its upper surface, a tank 12 that is long in the front-rear direction, and front and rear ends on both sides of the tank 12. Frame 15 including beam members 14a and 14b that connect a pair of columns 13 arranged on each side of the column 13 and the pair of columns 13 disposed on each side surface of the tank 12 to each other. A tank container provided with a scaffold 16 extending in the front-rear direction of the tank 12 and a ladder 17 that is installed on the top and bottom of the tank 12 in the vicinity of the scaffold 16. Are connected to the scaffold 16 adjacent to the ladder 17 at intervals in the front-rear direction of the tank 12 and are raised by rotation in the front-rear direction with the connection part 18 to the scaffold 16 as a fulcrum. A plurality of struts 19 that can be, are installed between the plurality of struts 19 has a configuration in which the hand rail 21 is provided to increase by the rotation of the fulcrum connecting portion 20 and each strut 19.

  In the tank container 10 of FIG. 1, an operator uses a ladder 17 to climb a scaffold 16 disposed above the tank 12, walks on the scaffold 16 to the vicinity of the manhole 11, and then liquids from the manhole. Work to put powder in and out. At this time, since the handrail 21 is provided in the scaffold 16, the worker can safely work on the scaffold without risk of falling under the tank. As shown in FIG. 1, it is preferable that a wire 23 is installed between the plurality of support columns 19 below the handrail 21. Thereby, it is possible to prevent the worker from falling under the tank through the lower side of the handrail 21. More preferably, the worker wears a safety belt, attaches the safety belt hook to the handrail 21, the support column 19, or the wire 23 and works on the scaffold 16 on the tank.

  As described above, the height of trailers loaded with tank containers is limited to a predetermined height or less by the Vehicle Restriction Ordinance of the Ministry of Land, Infrastructure, Transport and Tourism. It is difficult to provide a slide. Since the handrail 21 of the tank container 10 of the present invention can be lowered when the trailer loaded with the tank container 10 is driven by a towing vehicle, the handrail 21 is installed in the large tank as described above. However, it does not cause a problem in the vehicle restriction decree. When the trailer is stopped and the work is performed on the scaffold 16 on the tank 12, the handrail 21 is raised to ensure high safety of the work on the scaffold 16. When a plurality of tank containers 10 according to the present invention are stacked and stored in a container yard before being loaded on a trailer or a ship, if the handrail 21 is lowered, the handrail 21 and the column are supported. It is not necessary to remove 19 from the tank container.

  Next, the procedure for raising the handrail 21 of the tank container 10 will be described in detail.

  FIG. 2 is a diagram illustrating a state in which the handrail of the tank container in FIG. 1 is lowered. However, description of the wire 23 shown in FIG. 1 is omitted. As shown in FIG. 2, the plurality of struts 19 of the tank container 10 are connected to a scaffold 16 close to the ladder 17 at intervals from each other along the front-rear direction of the tank 12, and each strut 19 is connected to the scaffold 16. It is possible to start up by rotating in the front-rear direction with the connecting portion 18 as a fulcrum. Each column 19 may be connected to a beam member 14 a adjacent to the ladder 17.

  The connecting portion 18 of each support column 19 with the scaffold 16 is extended along the width direction of the scaffold below the scaffold 16 (from the front side to the far side of the sheet of FIG. 2). The extension part of this support | pillar 19 is fitted by the hole formed in each of the both sides | surfaces of the width direction of the scaffold 16 using a pair of support | pillar connection tool 25 fixed using the volt | bolt (FIG. 3:24), for example. It is supported by a pair of connection tools 25 in a freely rotatable state. Thereby, each support | pillar 19 can be started by rotation of the front-back direction which uses the connection site | part 18 with the scaffold 16 as a fulcrum.

  Each of the plurality of support columns 19 contacts the handrail 21 when rotated in the lower direction of the drawing with the connection portion 18 to the scaffold 16 as a fulcrum and disposed in the horizontal direction, and therefore is lower than the horizontal direction. The handrail does not rotate to the side (that is, the handrail does not further descend from this state), but the handrail is placed on the side surface of the scaffold 16 so that a large load (for example, the mass of the handrail) is not applied to the connection portion 18. It is preferable to provide the support tool 26 to support the handrail 21. The scaffold 16 may be provided with a plurality of handrail support tools along the front-rear direction of the tank 12.

  FIG. 3 is a diagram showing a state in the middle of raising the handrail of the tank container of FIG. As shown in FIG. 3, when each support column 19 is raised by rotation about the connection site 18 with the scaffold 16, the handrail 21 is connected to each of the above-mentioned connection sites 20 with each support column 19. It rises by the rotation of the column. In addition, the handrail 21 and each support | pillar 19 are each made rotatable with the pin 27 which connects both, for example as a fulcrum.

  As shown in FIG. 3, it is preferable that the ladder 17 is suspended above and below the tank on the rear surface side (or front surface side) of the tank 12. If the ladder is laid up and down on the side of the tank, when the worker moves from the top of the ladder to the scaffold (or moves from the scaffold to the top of the ladder), the raised columns and handrails are in the way Because it becomes. Even if the ladder is suspended on the top and bottom of the tank on the side of the tank, the worker can climb up the scaffolding and raise the column, or after raising the column, It is possible to climb on the scaffold from the top through the underside of the handrail.

  Further, it is preferable that each of the columns 19 can be raised to the ladder 17 side as shown in FIG. This is because it becomes easy for an operator who has climbed to the top of the ladder 17 to hold the column 19 by hand. Further, when the handle 22 is provided on the support column on the ladder 17 side, it is easier to start up the support column.

  FIG. 4 is a diagram showing a state in which the handrail of the tank container in FIG. 1 is raised. As shown in FIG. 4, when each of the support columns 19 stands up vertically to the scaffold 16, each support column stands upright by a support column temporary fixture 28 that connects the lower side of the support column 19 on the ladder 17 side and the scaffold 16. Temporarily fixed in the raised state. The temporary column support 28 is connected to the scaffold 16 via a pin 29, and can be rotated around a connection site with the scaffold 16 as a fulcrum. A long hole 30 is formed in the column temporary fixing tool 28 along its length direction, and this long hole 30 extends at one end of the long hole 30 in a direction substantially perpendicular to the long hole (FIG. 3). : 31). Then, when the support column 19 on the side of the scaffold 16 is raised vertically to the scaffold, the support column 19 and the temporary fixing device 28 are movable relative to each other in an extension portion (FIG. 3:31) of the long hole 30 of the support column temporary fixing device 28. In this state, the pins 32 that are connected are inserted, and each support column 19 is temporarily fixed in a state where it is raised vertically to the scaffold. Therefore, the handrail 21 is temporarily fixed in a state of being raised on the scaffold.

  Thus, since the tank container of this invention is equipped with the handrail which can be raised / lowered, even if it is a case where a tank enlarges, it is a useful thing which can ensure the high safety | security with a scaffold.

It is a perspective view which shows the structural example of the tank container with a handrail of this invention. It is a figure which shows the state which the handrail of the tank container of FIG. 1 fell. However, description of the wire 23 shown in FIG. 1 is omitted.
