Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics and warehousing, and specifically relates to a self-adaptive tray guiding device. BACKGROUND

[0002] In the logistics and warehousing industry, sea-air containers (sea shipping containers or air cargo containers) are widely used for cargo transportation. In order to improve the loading and unloading efficiency, many sea-air containers are provided with roller tracks inside. For example, as shown in Figure 1 and 2 Sea-air container 200, four roller tracks 201 are provided to tow different size trays (such as standard European trays, American trays, etc.). As shown in Figure 1 , when towing a large tray 202, four roller tracks 201 are used; as shown in Figure 2 , when towing a small tray 203, three adjacent roller tracks 201 are used. However, the roller tracks 201 lack effective guiding performance. When towing a large tray 202, the edges of the large tray 202 almost stick to the container wall (generally, angle iron 204 is installed on the container wall as a guide), and the large tray 202 will not deviate or jam during towing. However, when towing a small tray 203, the lack of effective guidance can easily cause the small tray 203 to deviate or jam during transportation.

[0003] In order to ensure the guiding performance, a guiding assembly needs to be provided, especially for the guiding assembly during the towing of a small tray. However, after the guiding assembly for the small tray is provided, the guiding assembly will affect the towing of a large tray, which leads to the fact that in actual operation, the user needs to frequently replace or adjust the guiding assembly, increasing the operation complexity and time cost.

[0004] Therefore, it is urgent to design a self-adaptive guiding assembly that can guide a small tray without affecting the towing of a large tray. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0029] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0030] As Figures 3-7 shown, the embodiment provides a self-adapting tray guiding device 100, including base 101, first rotating shaft 102, supporting arm 103, torsional spring (omitted in the drawing), limiting side plate 104, limiting top plate 105 and guiding fin plate 106. The first end of supporting arm 103 is rotatably connected with base 101 through first rotating shaft 102. The torsional spring is arranged on first rotating shaft 102, and two legs of the torsional spring act on base 101 and supporting arm 103 respectively to make the second end of supporting arm 103 have a lifting movement tendency. Limiting side plate 104 is fixed to the second end of the torsional spring. Limiting top plate 105 is fixed to the top of limiting side plate 104 and protrudes away from the side of supporting arm 103. Guiding fin plate 106 is vertically arranged on the side of limiting side plate 104 close to supporting arm 103 and is arranged at an obtuse angle with limiting side plate 104, the first end of guiding fin plate 106 is flush with limiting top plate 105, and the height of the first end to the second end of guiding fin plate 106 gradually decreases.

[0031] The adaptive tray guiding device 100 is installed on the bottom plate of the sea-air box 200, and is installed in two rows, one row is installed on the outer side of the first group of roller tracks 201 (referring to the side away from the second group of roller tracks 201), and the other row is installed between the third and fourth groups of roller tracks 201, a plurality of adaptive tray guiding devices 100 are installed in each row, and the adaptive tray guiding devices 100 in the two rows are arranged towards each other (referring to the second ends of the supporting arms 103 being close to each other). In the initial state, under the action of the torsional spring, the second end of the supporting arm 103 is lifted to a certain height (limited by the limiting block 1012, and will not be lifted all the time), at this time, the limiting side plate 104 is nearly perpendicular to the bottom plate of the sea-air box 200, the limiting top plate 105 is nearly parallel to the bottom plate of the sea-air box 200, the small tray 203 is towed on the first to third groups of roller tracks 201, the two side edges of the small tray 203 are located between the two limiting side plates 104, and the two side edges of the small tray 203 are located below the two limiting top plates 105, and the limiting side plate 104 and the limiting top plate 105 are used for limiting and guiding the small tray 203; when the large tray 202 is towed, the bottom of the large tray 202 acts on the upper edge of the guiding fin 106, forcing the guiding fin 106 to move downward, thereby driving the limiting side plate 104, the limiting top plate 105 and the second end of the supporting arm 103 to move downward, and finally the part of the supporting arm 103 that is above the track is completely hidden below the large tray 202, so as not to affect the towing of the large tray 202. In summary, the adaptive tray guiding device 100 provided by the utility model can adaptively adjust the large tray 202 and the small tray 203, can limit and guide the small tray 203, and does not affect the towing of the large tray 202. In addition, the design that the guiding fin 106 is arranged at an obtuse angle with the limiting side plate 104 can correct the slightly skewed small tray 203 during towing, and force the towing direction of the small tray 203 to be consistent with the extension direction of the roller track 201.

[0032] In the embodiment, the base 101 includes a rectangular frame 1011 with an upper opening and a lower opening, and the two ends of the first rotating shaft 102 are rotatably penetrated into two oppositely arranged vertical plates of the rectangular frame 1011 (the two vertical plates are provided with penetrating holes). It should be noted that the two ends of the first rotating shaft 102 can also be fixed in the penetrating holes, and the first end of the supporting arm 103 is provided with a penetrating hole, and the first end of the supporting arm 103 is rotatable relative to the first rotating shaft 102, so that the pivoting of the supporting arm 103 around the shaft can also be ensured. It should be noted that the base 101 can also adopt a non-rectangular frame structure, or even a non-frame structure, as long as the purpose of realizing the rotatable arrangement of the first rotating shaft 102 and the fixation of the base to the bottom plate of the sea-air box can be achieved.

[0033] In the embodiment, the base 101 further comprises a limiting block 1012, which is arranged inside the bottom of the rectangular frame 1011. When the second end of the support arm 103 is lifted to a set height, the first end of the support arm 103 will abut against the limiting block 1012. Specifically, the limiting block 1012 is located below the first rotating shaft 102 and away from one side of the limiting side plate 104. When the second end of the support arm 103 moves downward, the first end of the support arm 103 will move away from the limiting block 1012, and vice versa. When the first end of the support arm 103 abuts against the support block, the second end of the support arm 103 will no longer be lifted upward.

[0034] In the embodiment, the bottom outside of the rectangular frame 1011 is provided with a horizontal bottom foot 1013, which is provided with a vertical through hole.

By providing the concave slot 1061, when the large tray 202 presses down the limiting side plate 104 and other structures, the guide fin plate 106 can be prevented from being in contact with the rectangular frame 1011.

[0037] In the embodiment, the adaptive tray guide device 100 further comprises a second rotating shaft (hidden and not shown in the figure) and a cylindrical roller 107. The limiting side plate 104 is provided with a window 1041, the second rotating shaft is vertically arranged in the window 1041, and the cylindrical roller 107 is sleeved and fixed on the second rotating shaft. By providing the rotatable cylindrical roller 107, the sliding friction is changed to rolling friction in the process of guiding and limiting the small tray 203, so as to reduce the towing resistance of the small tray 203. The cylindrical roller 107 can be provided with a plurality of, and the number of the cylindrical roller 107 is determined according to the size of the window 1041, and the size of the window 1041 is determined according to the length of the limiting side plate 104. In addition, a vertical through mounting hole can also be arranged on the limiting top plate 104, and a horizontal roller is installed in the mounting hole, further reducing the towing resistance of the small tray 203.

[0038] In the embodiment, the rectangular frame, the bottom foot and the limiting block are welded and fixed or integrally formed, and the support arm, the limiting side plate, the limiting top plate and the guide fin plate are welded and fixed or integrally formed, so as to improve the connection strength.
