Description

Special elevator with vertical conveyor function {SPECIAL ELEVATOR WITH VERTICAL CONVEYOR FUCTION}

The present invention relates to a special elevator equipped with a vertical conveyor function, and more specifically, to a special elevator equipped with a vertical conveyor function whose entrance and exit are twisted in different directions.

Elevators have been developed in various forms, and are generally divided into passenger use and industrial use. There are various types of industrial elevators, but elevators that transport high loads such as cargo are generally called special elevators. The above special elevators are used in a variety of fields, and recently, demand has been rapidly increasing in large shipyards that need to build LNG ships in large quantities.

Since the work on the heat insulator of an LNG ship requires transferring the heat insulator into the ship's LNG cargo tank (CARGO TANK), the above work is mainly performed using a crane at shipyards. At this time, when using a crane, it takes a lot of time to transport the heat insulating material, and the crane cannot be used for other purposes, which causes a delay in the ship construction work. In particular, since the construction period for an LNG ship takes longer than that of a typical ship, there is a need for a lifting system that can quickly handle heat insulating material work in a safer situation.

Korean Patent Publication No. 10-2015-0035051 (hereinafter referred to as 'prior art') discloses an insulating box transfer device for an LNG cargo hold and a transfer method thereof. Referring to FIG. 1, the insulation box transfer device of the LNG cargo hold of the prior art includes a line tracer (2) for loading and transporting an insulation box (1), and a line tracer (2) for moving the insulation box loaded on the line tracer (2). It is configured to include an elevator (3) that goes up and down the floor. As mentioned above, heavy insulation boxes are transported using line tracers and elevators, which reduces worker fatigue and allows work to be managed efficiently.

In systems that transport cargo using special elevators, as in the prior art above, there is a problem that the locations where they can be installed and utilized are limited because the entrances and exits of the special elevators are the same on multiple floors. In addition, because special elevators for high loads are generally installed in narrow spaces, special elevators with entrances and exits in different directions are required.

At this time, the pair of rotation shafts 322 may be arranged to be spaced apart in the front and rear directions so that one transport chain 321 surrounds them, and the second motor 323 may be operated based on the left and right direction in which the rotation shaft 322 extends. ), a rotational force is generated and the cargo 30 can be transported in the forward and backward directions. Here, the plurality of transport chains 321 may be disposed between the plurality of transport rollers 311. And the upper surface of the fixed frame 313 disposed between the pair of adjacent transport rollers 311 is depressed downward so that one transport chain 321 is disposed at the upper end and one of the rotating shafts 322 The lower end of one wrapped transport chain 321 may extend to the lower side of the fixed frame 313 to surround the other rotating shaft 322.

The platform conveyor 300 can control the height of the first transfer unit 310 or the second transfer unit 320. At this time, if the height of the transport roller 311 of the first transport unit 310 or the transport chain 321 of the second transport unit 320 is controlled and the lifting platform 220 is located on one floor, the transport If the upper end of the roller 311 is placed higher than the upper end of the transport chain 321 and the lifting platform 220 is located on another level, the upper end of the transport chain 321 is higher than the upper end of the transport roller 311. It can be placed higher than the top. Accordingly, the cargo 30 is placed on the transport roller 311 on one floor, and the cargo 30 is placed on the transport chain 321 on the other floor, so that the cargo 30 can be transported in different directions. . Here, one layer may be a layer where the first conveyor 100 is placed and the other layer may be a layer where the second conveyor 400 is placed.

The platform conveyor 300 further includes an inlet stopper 330 that limits the position of the other side of the loaded cargo 30 on one side in the left and right directions, and the inlet stopper 330 is arranged to be spaced apart in the forward and backward directions, but in the up and down directions. It may include a plurality of damping members 331 rotated about the axis. Here, the inlet stopper 330 is fixed to the other side in the left and right directions of the first transfer unit 310 or the second transfer unit 320 so that the cargo 30 introduced from one side can be stopped at the inlet stopper 330. It can be guided, and damage to the cargo 30 due to external force can be prevented through the plurality of damping members 331.

The platform conveyor 300 further includes a support member 340 that adjusts the height of the fixing frame 313 of the first transport unit 310 so that the transport roller 311 of the first transport unit 310 moves up and down. can do. The support member 340 may include a lifting cylinder 341 fixed to the inner floor of the lifting platform 220 and whose length is adjusted up and down. When the height of the lifting cylinder 341 becomes longer, the first transfer unit (310) rises so that the cargo is transported left and right by the first transfer unit 310, and when the height of the lifting cylinder 341 is lowered, the first transfer unit 310 is lowered so that the cargo is transferred to the second transfer unit. It can be implemented to be transported back and forth by (320). And, as shown in FIG. 10, the second conveyor 400 may also include a transfer means 410 implemented as a roller or a belt, and cargo is transported through the second transfer unit 320 of the platform conveyor 300. It may be configured to receive (30) and transport the cargo (30) from the relevant floor to the work location through the transport means (410).
