The side pad and the head pad of the dock shelter are in a contracted state because they are pulled in a direction in which the parallel link is contracted by the reduction wire. Also, when the pressure plate on the front of the platform is pushed down at the rear of the vehicle, it is pulled in the direction in which the parallel link is expanded by the extension wire, so that the side pads and the head pad are pushed open, and Adhered to the top. The gap between the platform and the platform of the insulated truck is closed by bottom pads installed between the rails buried on both sides of the cargo unloading port.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a dock shelter according to the present invention will be described below with reference to the drawings. Further, in each embodiment, the same components are denoted by the same reference numerals, and only different components are denoted by different reference numerals.
[0008]
As shown in FIGS. 1 to 3, a dock shelter 1 according to the first embodiment has a side pad 3 installed opposite to both side walls 2 a of a cargo unloading port 2 of a building, and a front side of the side pad 3. It is composed of a head pad 4 installed on the side ceiling surface 2b and a pressure receiving plate 6 installed on the front surface of the platform 5. The side pad 3 and the head pad 4 are connected to a reduction wire 8 having a counterweight 7 and an expansion wire 10 wound around a winding drum 9 of a pressure receiving plate.
[0009]
As shown in FIGS. 4 and 5, the side pad 3 includes a pair of double parallel links 11, a pad 12 made of a soft urethane resin provided on the front side of the double parallel links 11, and a double parallel link 11. And a covered bellows sheet 13. The double parallel link 11 is formed by joining a fixed bar 14 fixed to the side wall 2 a and a movable bar 15 with a link 17 via a connecting bar 16, and the movable bar 15 is supported by casters 18. A link support shaft 19 is provided between the double parallel links. The reduction wire 8 is connected to the upper side of the wire clamp 20 of the link support shaft 19, and the extension wire 10 is connected to the lower side thereof. Therefore, when the double parallel link 11 is pulled upward by the reduction wire 8 (counter weight), the side pad 3 is in a contracted state (see FIG. 4), but the double parallel link 11 is opposed to this force. When it is pulled down by the extension wire 10, it expands (see FIG. 5).
[0010]
On the other hand, as shown in FIGS. 6 and 7, the head pad 4 also includes a pair of double parallel links 11 on both sides, a soft urethane resin pad 12 provided below the link 11, and a double parallel link. And a covered bellows sheet 13. The double parallel links 11 on both sides are also formed by joining a fixed bar 14 fixed to the ceiling surface 2b and a movable bar 15 with a link 17 via a connecting bar 16. At the center of the movable bar 15 of the double parallel link 11, two reduction wires 8 are connected from both ends via guide sheaves 31, and a link support shaft 19 between the double parallel links 11 is The extension wire 10 is connected via the guide pulley 31. Therefore, when the movable bar 15 is pulled upward by the reduction wire 8, the head pad 4 is in a contracted state (see FIG. 6), but the double parallel link 11 is moved outward by the expansion wire 10 against this force. When pulled, it expands (see FIG. 7).
[0011]
As shown in FIGS. 8 to 10, the pressure receiving plate 6 is configured such that a U-shaped fixed plate 21 installed on the front surface of the platform 5 and a U-shaped movable plate 22 face each other. The movable plate 22 is slidably inserted into the guide tube 24 of the fixed plate 21, and the movable plate 22 is projected outward by a spring 25.
[0012]
A pinion gear 27 is provided on the support shafts 26 on both sides of the movable plate 22, and meshes with a rack gear 28 on both side walls 2a. A winding drum 9 composed of a wire drum 29 for a side pad and a wire drum 30 for a head pad having a larger diameter is provided below the support shaft 26. The wire drum 29 for the side pad has a side pad One end of the extension wire 10 that pulls the extension wire 3 in the direction in which it is extended is connected, and the other end is connected to the link support shaft 19 between the double parallel links via the guide pulley 31 (see FIGS. 8 and 9). .
[0013]
One end of the extension wire 10 that pulls the head pad 4 in the direction to expand the head pad 4 is also connected to the head pad wire drum 30, and the other end is connected to the link support shaft 19 between the double parallel links via the guiding pulley 31. It is connected to the. Therefore, the double parallel link 11 on both sides is pulled in the direction of expansion by the expansion wires 10 from both sides. The extension wire 10 is provided with an adjustment spring 32 for preventing cutting due to excessive pulling.
[0014]
Therefore, as shown in FIG. 10, when the movable plate 22 is pushed down (slid) toward the fixed plate 21, the rotation of the pinion gear 27 causes the wire drum 29 for the side pad and the wire drum 30 for the head pad to expand. Since 10 is wound up, the double parallel link 11 between the side pad 3 and the head pad 4 is pulled in the direction in which it is expanded. Since this pulling force is larger than the pulling force due to the reduction wire 8, the side pad 3 and the head pad 4 simultaneously expand inward or downward against this force.
[0015]
FIGS. 11 to 14 show an operation state of the dock shelter 1. When the cold storage vehicle 33 is not docked on the platform 5, the side pad 3 and the head pad 4 are pulled by the reduction wire 8. And is in a contracted state (see FIGS. 11 and 12). In this state, the refrigerating car 33 is retracted, and when the movable plate 22 of the pressure receiving plate 6 is pushed down (slid) at the rear of the loading platform 34, the pinion gear 27 rotates and the side pad wire drum 29 and the head pad wire drum 30 Then, in order to wind up the extension wire 10 for the side pad and the extension wire 10 for the head pad, the double parallel link 11 between the side pad 3 and the head pad 4 is pulled in the extending direction. Since this pulling force is larger than the pulling force of the reduction wire 8, the side pad 3 and the head pad 4 simultaneously expand inward or downward against this force, and the both sides and the upper portion of the bed 34 of the cold-storage vehicle are formed. (See FIGS. 13 and 14). During the loading and unloading of the articles, the side pads 3 and the head pads 4 are in close contact with both sides and the upper part of the carrier 34 of the insulated car, thereby ensuring airtightness.
[0016]
Next, when the loading / unloading operation is completed and the insulated truck 33 is separated from the platform 5, the movable plate 22 returns to its original state by the spring 25, and the pinion gear 27 rotates in the reverse direction. By this reverse rotation, the extension wire 10 for the side pad and the extension wire 10 for the head pad, which have been wound on the wire drum 29 for the side pad and the wire drum 30 for the head pad, are rewound and the reduction wire 8 Since the side pad 3 and the head pad 4 are pulled, they are in a contracted state as shown in FIG.
[0017]
Further, when the movable plate 22 is pushed down (slid) by the cargo bed 34 of the cold storage vehicle and hits the fixed plate 21, the side pad 3 and the head pad 4 are expanded most, and the stroke of the smallest cold storage vehicle is reduced. The width is set to be in close contact with the loading platform 34. Therefore, even when the movable plate 22 is pushed down (slid) by the loading bed 34 of the cooler car, the movable plate 22 moves by the same stroke to expand the side pad 3 and the head pad 4. However, since these extra forces are attenuated by the adjusting springs 32 after they come into close contact with the carrier 34 of the cold storage vehicle, no extra tension is applied to the extension wire 10 and breakage due to excessive pulling can be prevented. It has become.
[0018]
FIGS. 15 and 16 show a dock shelter 35 according to the second embodiment, in which a gap 36 formed between the platform 34 and the platform 5 of an insulated car is buried in both side walls 2 a of the cargo unloading port 2. It is closed by a bottom pad 38 installed between the rails 37.
[0019]
The bottom pad 38 includes a pad body 39 made of hard urethane resin and an elastic member 40 made of soft urethane resin provided on the front surface thereof. The protrusions 41 on both side walls of the pad body 39 are fitted to the rail 37. I have. Two wires 43, 44 connected to the bottom pad weight 42 are connected to the projection 41, and one of the wires 43 is connected to one of the double pulleys 45 a via another pulley 46. The other pulley 44 is connected to the other pulley 45 via the other pulley 47 and the other pulley 47. Each pulley in the double pulley 45 is configured to rotate independently. Further, the bottom pad weight 42 also serves to fix the bottom pad 38.
[0020]
Therefore, as shown in FIG. 16 (2), the bottom pad 38 is lowered along the rail 37 to close the gap 36. Since the bottom pad 38 moves up and down on the rail 37 in this manner, as shown in FIG. 15, the gap 36 opened between the rear portion of the cargo bed 34 of the insulated car and the platform 5 is easily closed.
[0021]
【The invention's effect】
When the pressure plate at the front of the platform is pushed down (slid) at the rear of the vehicle, the extension wire pulls the parallel link in the direction in which the parallel link is extended, so that the side pads and the head pad are pushed open, and the cargo bed of the cold storage vehicle is pushed. Can be brought into close contact with both sides and the upper part of the.
[0022]
The gap between the platform and the platform of the insulated truck can be closed by the bottom pad installed between the rails buried on both sides of the loading / unloading port, so that confidentiality can be maintained .
