Abstract

PURPOSE:To open/close a door by performing the removal/fitting of packing and the clamping/release of clips simultaneously by air cylinders, link mechanism, and the like so as to attain the rapidity, simplicity and safety of work. CONSTITUTION:A rod 15 put in reciprocating motion by an air cylinder 16 is provided with a pair of wedges 20, 21. With this reciprocating motion, a longitudinal pin 19 is moved longitudinally to become a force point, so that the respective upper and lower action points of a door are moved with a roller 8 as a fulcrum to remove/fit packing 24, 25 and a coaming. The reciprocating motion of four air cylinders 16 is connected to quadrangular link mechanism, and the link mechanism is reciprocated in the same direction. Accordingly, when clips 14 are provided in the same direction and the rods 15 are put in reciprocating motion, the clips 14 are rotated simultaneously so as to be clamped and released.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large slide type watertight door provided on a watertight bulkhead of a car carrier or the like.

[0002]

2. Description of the Related Art Conventionally, in the invention of this type, an appropriate number of clips are provided on the outer edge of the door, and the door is opened and closed by removing the wire with a winch.

When the door is opened and closed, dozens of clips arranged on the door are manually opened and closed.

Further, since the door is large, a person who cannot reach a person's spine climbs a step with a door and works in a bad posture, which requires a great amount of force.

To attach and detach the packing, a screw is provided at one end of the support arm, and the screw is turned left and right by a manual wheel to move the door, thereby adjusting the combing and the contact of the packing.

[0006]

As described in the prior art, the door clip is manually tightened and released, and the packing is manually attached and detached, which requires a long time for opening and closing work. However, there was a problem that it was dangerous.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to attach and detach the packing and to tighten and release the clip with an air cylinder and a link mechanism. All at once,
By opening and closing the door, it aims to speed up work, simplify the work, and ensure safety.

[0008]

In order to achieve the above object, the present invention employs a wedge mechanism for attaching and detaching a packing and a link mechanism for changing the reciprocating motion into a rotary motion for opening and closing a clip, It activates dozens of clips at the same time.

[0009]

According to the present invention, a pair of wedges are provided on the rod that reciprocates by the air cylinder, and when reciprocating, the vertical pin is moved back and forth to act as a force point, and the roller serves as a fulcrum, so that the upper and lower action points of the door are Move and remove packing and combing.

Further, the reciprocating motions of the four air cylinders are connected to a rectangular link mechanism, and the link mechanisms reciprocate in the same direction. Clips are provided in the same direction to reciprocate the rod. And rotate all at once to tighten and release the clip.

EXAMPLES Examples will be described with reference to the drawings.
As shown in FIGS. 1, 2 and 3, an opening 2 is provided in the partition wall 1 in order to improve the traffic between the partition walls of a car carrier. The opening 2 is opened to improve traffic during cargo handling, and is closed during operation for safety of fire and flooding of compartment.

The door 3 is supported by supporting arms 6 and 7, and is adapted to travel on an upper rail 4 and a lower rail 5 by rollers 8.

The door 3 is driven by a twin barrel winch drum 9
From each of the doors, the wire 11 is inserted in the reverse winding, and the endless rope is obtained through the several sheaves 10, several places are pivotally attached to the upper end of the door 3, and the winch drum 9 is normally or reversely rotated. It is intended to open and close.

A round bar 13 is provided at one end of each of the support arms 6 and 7, and a tip of a column 12 pivotally attached to the door 3 is formed into a hook shape.
A hook is hooked at 3, a door 3 is held, a roller 8 is pivotally attached to the other end, and the upper rail 4 and the lower rail 5 are tracked.

On the outer edge of the door 3, a required number of clips 14 are pivotally attached to the door 3, and the clips 14 are pivotally attached to rods 15 on four sides so as to be in the same direction, and are connected at four corners of the rod 15. , Has a link mechanism.

Air cylinders 16 are provided on the rods 15, respectively, and reciprocating motions simultaneously rotate the clips 14, thereby sliding and tightening the wedge seats 17 provided on the partition wall 1. Is done. Further, the release is similarly performed by the reverse operation.

The rod 15 is provided with supporting arms 6 and 7. A vertical pin 19 supported by a bracket 18 is provided at an intermediate portion of the supporting arms 6 and 7, and the rod 15 is paired with the vertical pin 19 interposed therebetween. By providing the wedges 20 and 21 of the pair, and the reciprocating motion of the air cylinder 16, the vertical pin 19 is moved to the pair of wedges 2.
By sliding 0 and 21, it becomes a force point, and the roller 8 is used as a fulcrum to move the round bar 13 of the action point, the door 3 main body is moved, and the combings 22 and 23 and the packings 24 and 25 are attached and detached.

A combing 22 is erected on the outer edge of the door 3 to form a U-shaped groove, a watertight packing 24 is attached to the groove, and a combing 23 is erected on the edge of the partition wall 1. A U-shaped groove is formed, and a gas-tight packing 25 is attached to the groove so that the combings 22 and 23 can be attached and removed over the entire circumference.

The open / closed display is detected electrically from the operation of the rod 15 and displayed at a remote control location.

[0019]

Since the present invention is configured as described above, it has the following effects. The present invention aims at quickness, simplicity and safety of the work by attaching and detaching the packing by the air cylinder and tightening and releasing the clip.
