Description

Technical Field

[0001] This invention relates generally to the technical field of cargo boxes and containers, and more specifically to a bracket support device and a container. Background Technology

[0002] Containers can carry packaged or unpackaged goods for sea, land, and air transport, making them an important mode of transport in international trade multimodal transport. Containers do not require moving the goods inside during transshipment, allowing for rapid loading and unloading as a single transport unit. They are easy to handle using mechanical equipment and can be reused repeatedly over a long period. Using containers for freight transport can greatly improve transport efficiency and reduce transport costs.

[0003] Currently, the logistics market has an urgent need for international transportation solutions for automobiles. Containerized transport is the most important mode of logistics transportation in the world today, enabling the rapid, efficient, low-cost, and highly secure flow of goods. Some transport vehicles use rack-type containers, equipped with key components such as bottom side beams, folding end frames, and lane brackets. Inside the rack-type container, a bracket support device is located between the bottom side beams and the lane brackets to keep the lane brackets in an inclined position. Most existing bracket support devices are located on the bottom side beams, occupying the vertical space above the bottom side beams and reducing the space utilization rate of the container.

[0004] Therefore, there is a need to provide a bracket support device or container to at least partially solve the above problems. Summary of the Invention

However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0093] To fully understand the present invention, a detailed description will be set forth in the following description. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. Obviously, the implementation of embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described in detail below; however, in addition to these detailed descriptions, the present invention may have other embodiments.

[0094] The ordinal numbers such as "first" and "second" used in this invention are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term "first component" does not imply the existence of "second component," and the term "second component" does not imply the existence of "first component."

[0095] It should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer" and similar expressions used in this invention are for illustrative purposes only and are not intended to be limiting.

[0096] This invention discloses a bracket support device and a container.

[0097] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings.

[0098] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in a preferred embodiment, a bracket support device 105b includes: a first support rod 106a, a second support rod 106b, a third support rod 106c, and a locking device 107.

[0099] The first end of the first support rod 106a is used to hinge with the lane bracket 104b of the container 100. The upper end of the first support rod 106a shown in the figure is its first end.

[0100] The first end of the second support rod 106b is used to hinge with the underframe assembly 101 of the container 100. The lower end of the second support rod 106b shown in the figure is its first end.

[0101] The first end of the third support rod 106c is used to hinge with the underframe assembly 101 of the container 100. The lower end of the third support rod 106c shown in the figure is its first end.

[0102] The locking device 107 is disposed on the third support rod 106c and can move and lock on the third support rod 106c. The second end of the first support rod 106a is hinged to the locking device 107, and the second end of the second support rod 106b is hinged to the locking device 107. The first support rod 106a and the second support rod 106b can be folded and unfolded relative to each other.

[0103] like Figure 4 , Figure 5 As shown, when the lane bracket 104b is needed, the bracket support device 105b is unfolded. The first support rod 106a, the second support rod 106b, and the third support rod 106c have a star-shaped structure. At this time, the locking device 107 locks on the third support rod 106c to maintain the relative positional relationship of the first support rod 106a, the second support rod 106b, and the third support rod 106c.

[0104] like Figure 6 As shown, when the lane bracket 104b is not needed, the bracket support device 105b is folded. At this time, the locking device 107 can move on the third support rod 106c, and the first support rod 106a and the second support rod 106b are folded relative to each other until the overall height of the bracket support device 105b is reduced to approximately equal to the height of the first support rod 106a and the second support rod 106b stacked on top of each other.

[0105] In this embodiment, the bracket support device 105b is equipped with three support rods, which is shorter than the single support rod in the prior art. This reduces the operating angle of the support rods and the travel of the locking device 107, saving the space required for installation in the container 100 and reducing the impact of the bracket support device 105b on the loading space of the container 100.

[0106] In one implementation, such as Figure 4 , Figure 5 As shown, the second end of the first support rod 106a and the second end of the second support rod 106b are both provided with obtuse angle bending structures. When the first support rod 106a and the second support rod 106b are folded relative to each other, the two obtuse angle bending structures are arranged opposite each other, so that the first support rod 106a and the second support rod 106b can be folded in an up-and-down overlapping manner.

[0107] With this configuration, the first support rod 106a and the second support rod 106b can avoid each other when folded relative to each other, thereby reducing the overall height of the folded bracket support device 105b and minimizing the impact of the folded bracket support device 105b on the height of the container 100, which facilitates the storage and transportation of the folded container 100.

[0108] In one embodiment of the obtuse angle bending structure, such as Figure 4 , Figure 5 , Figure 6 As shown, the second lug 110 is provided with an obtuse angle bending structure, and when the first support rod 106a and the second support rod 106b are folded relative to each other, the obtuse angle bending structures of the two second lugs 110 are arranged opposite to each other, so that the first support rod 106a and the second support rod 106b can be folded in an up-and-down overlapping manner.

[0109] In the figure, the obtuse angle of the second lug 110 of the first support rod 106a is greater than that of the second lug 110 of the second support rod 106b. With this setting, the first support rod 106a and the second support rod 106b can avoid each other when folded relative to each other, and can finally fit together vertically, reducing the overall height of the bracket support device 105b to about equal to the height of the first support rod 106a and the second support rod 106b stacked vertically.

[0110] In one implementation, such as Figure 4 , Figure 5 As shown, the first end of the first support rod 106a and the first end of the second support rod 106b are both provided with a first lug 111, and the second end of the first support rod 106a and the second end of the second support rod 106b are both provided with a second lug 110. The first lug 111 and the second lug 110 include one lug plate or two lug plates, and the distance between the two lug plates is greater than the thickness of one lug plate.

[0111] Both the first support rod 106a and the second support rod 106b may include, for example: Figure 8 The support rod body 109 shown is a rectangular or round tube. A groove 192 is provided at the first end of the support rod body 109, suitable for mounting one lug. A protrusion 191 is provided at the second end of the support rod body 109, suitable for mounting two lugs. The lugs have an appropriate thickness, high structural strength, and are not easily deformed during use. Hinge holes are provided on them for connection. The lugs and the support rod body 109 can be fixedly connected by welding.

[0112] The third support rod 106c may include, for example, Figure 9 The support rod body 113 shown is a rectangular tube or a round tube, and a hinge hole 302 is provided at the first end for hinge connection with the base frame assembly 101 of the container 100.

[0113] In one implementation, such as Figure 4 , Figure 5As shown, the second lug 110 of the first support rod 106a and the second lug 110 of the second support rod 106b have different numbers of lug plates, allowing the second lug 110 with one lug plate to be inserted into the second lug 110 with two lug plates. The second lug 110 of the first support rod 106a includes two lug plates, with the distance between the two lug plates greater than the thickness of one lug plate. The second lug 110 of the second support rod 106b includes one lug plate. The second lug 110 of the second support rod 106b can be inserted into the second lug 110 of the first support rod 106a. With this arrangement, the first support rod 106a and the second support rod 106b can overlap in the height direction and will not obstruct each other during rotation.

[0114] In one implementation, such as Figure 7 As shown, the first support rod 106a and the second support rod 106b are offset to the left and right, so that the first support rod 106a and the second support rod 106b can be folded in a left-right overlapping manner.

[0115] In the figure, the second lug 110 of the first support rod 106a and the second lug 110 of the second support rod 106b include the same number of lugs, each including one lug, or each including two lugs. The two second lugs 110 no longer have an interlocking relationship, but are staggered left and right. The first support rod 106a and the second support rod 106b do not obstruct each other when folded relative to each other, and can eventually fit together left and right, reducing the overall height of the bracket support device 105b to about equal to the height of the first support rod 106a or the second support rod 106b.

[0116] In one implementation, such as Figure 4 , Figure 5 , Figure 10 As shown, the locking device 107 includes: a sliding sleeve 112, a rotating shaft 116, and at least one positioning pin 115;

[0117] The sliding sleeve 112 is sleeved on the third support rod 106c. The sliding sleeve 112 is a rectangular tube or a round tube. The sliding sleeve 112 is provided with at least one second through hole along the direction perpendicular to the moving direction. The third support rod 106c is provided with a plurality of first through holes 301. The sliding sleeve 112 moves on the third support rod 106c so that the second through hole can be aligned with the first through hole 301 at different positions.

[0118] The rotating shaft 116 is located on the first side of the sliding sleeve 112, and the second end of the first support rod 106a and the second end of the second support rod 106b are both hinged to the rotating shaft 116.

[0119] The positioning pin 115 can be inserted into the first through hole 301 and the second through hole to lock the sliding sleeve 112 on the third support rod 106c.

[0120] Multiple positioning pins 115 can be provided to improve the connection strength between the sliding sleeve 112 and the third support rod 106c, improve the stability of the locked state, and enable the lane bracket 104b to support vehicles with greater weight.

[0121] During the relative unfolding and folding of the first support rod 106a and the second support rod 106b, the sliding sleeve 112 is movable on the third support rod 106c. After the first support rod 106a and the second support rod 106b have finished unfolding, the sliding sleeve 112 is locked on the third support rod 106c and cannot move further, thereby maintaining the unfolded state of the first support rod 106a and the second support rod 106b.

[0122] In one implementation, such as Figure 10 As shown, the sliding sleeve 112 also includes: a sliding sleeve body 119 and a reinforcing plate 118;

[0123] The sliding sleeve body 119 is a circumferentially closed tube structure or a circumferentially semi-closed tube structure; in the figure, the sliding sleeve body 119 is a circumferentially semi-closed tube structure with a U-shaped cross-section.

[0124] A reinforcing plate 118 is disposed on the side of the sliding sleeve body 119 near the rotating shaft 116. The rotating shaft 116 is fixedly connected to the reinforcing plate 118, and the thickness of the reinforcing plate 118 is greater than the thickness of the sliding sleeve body 119.

[0125] The reinforcing plate 118 and the sliding sleeve body 119 can be fixedly connected by welding, and the rotating shaft 116 and the reinforcing plate 118 can be fixedly connected by welding. The reinforcing plate 118 is set on the main stress-bearing side of the sliding sleeve 112. This setting can improve the structural strength of the sliding sleeve 112, making it less prone to deformation during use, maintaining its movable relationship with the third support rod 106c, and preventing the sliding sleeve 112 from failing when subjected to large shear forces and torsional stresses.

[0126] To improve the structural strength of the rotating shaft 116 and prevent it from deforming under stress, a reinforcing rib 117 can be provided at the connection between the rotating shaft 116 and the reinforcing plate 118 to improve the connection strength between the rotating shaft 116 and the reinforcing plate 118, thereby preventing the rotating shaft 116 from tilting during use and maintaining the structural relationship between the first support rod 106a, the second support rod 106b and the locking device 107.

[0127] In one implementation, such as Figure 10 , Figure 11 As shown, the locking device 107 also includes: a pin retainer 120;

[0128] The pin retainer 120 is located on the second side of the sliding sleeve 112. The pin retainer 120 is L-shaped and includes a base plate 201 and a side plate 202. The base plate 201 is fixedly connected to the sliding sleeve 112, which can be fixed by welding. The side plate 202 is provided with at least one positioning hole 203. The positioning pin 115 passes through the sliding sleeve 112 and the third support rod 106c and is connected to the positioning hole 203, which can improve the stability of the positioning pin 115 on the sliding sleeve 112. The number of positioning holes 203 is the same as the number of positioning pins 115.

[0129] In one implementation, such as Figure 4 , Figure 5 , Figure 12 As shown, the positioning pin 115 includes: a cylindrical pin 121 and a plug handle 122;

[0130] The first end of the cylindrical pin 121 is set as a plug-in end, and the plug-in end is set as a cone shape, which facilitates insertion into the second through hole of the sliding sleeve 112 and the first through hole 301 of the third support rod 106c, and also facilitates connection to the positioning hole 203 of the pin retainer 120.

[0131] The first end of the plug handle 122 is fixedly connected to the second end of the cylindrical pin 121, which can be fixed by welding. The cylindrical pin 121 is plugged into or separated from the sliding sleeve 112 by operating the plug handle 122. The second end of the plug handle 122 is provided with a backstop structure, which is L-shaped. After the cylindrical pin 121 is plugged into the sliding sleeve 112, the third support rod 106c is connected through the backstop structure to prevent the cylindrical pin 121 from separating from the sliding sleeve 112.

[0132] The insertion handle 122 has two bent structures that are not on the same plane, allowing the third support rod 106c to be connected while the cylindrical pin 121 is inserted into the sliding sleeve 112. To disassemble the positioning pin 115, simply rotate the insertion handle 122 in the opposite direction to release the connection with the third support rod 106c and separate the cylindrical pin 121 from the sliding sleeve 112.

[0133] In one implementation, such as Figure 11 , Figure 12 As shown, the base plate 201 is provided with at least one insertion hole 204, and the side plate 202 is provided with at least one slot 205. The idle positioning pin 115 is installed on the pin retainer 120. The cylindrical pin 121 of the positioning pin 115 is inserted into the insertion hole 204, and the handle of the positioning pin 115 is inserted into the slot 205. This can prevent the positioning pin 115 from being lost after disassembly, and also facilitates the quick connection of the positioning pin 115 and the sliding sleeve 112 when it is necessary to lock the sliding sleeve 112 and the third support rod 106c, thereby improving the unfolding efficiency of the bracket support device 105b.

[0134] In one implementation, such as Figure 4 , Figure 5 , Figure 9 As shown, a limiting rod 114 is provided at the second end of the third support rod 106c. The limiting rod 114 can block the movement of the sliding sleeve 112 and prevent the sliding sleeve 112 from detaching from the second end of the third support rod 106c.

[0135] The limiting rod 114 can be fixed to the third support rod 106c along the width direction of the third support rod 106c by a single bolt. Because the first end of the third support rod 106c is hinged to the base frame assembly 101 of the container 100, the sliding sleeve 112 cannot detach from the first end of the third support rod 106c, so it is only necessary to set the limiting rod 114 at the second end of the third support rod 106c.

[0136] In one implementation, such as Figure 13 As shown, the positioning pin 115 can be replaced by a positioning pin 136 with a simpler structure, including a pin handle and a locking plate, to simplify the structure, reduce manufacturing costs, or by other pins that can meet the limiting function.

[0137] In one embodiment, the locking device 107 may also take other structural forms, such as Figure 14 As shown, the locking device 107 includes:

[0138] Guide seat 132 is disposed at the second end of the third support rod 106c and is coaxial with the third support rod 106c; guide seat 132 and the third support rod 106c can be fixedly connected by welding.

[0139] Adjusting screw 133 is set in guide seat 132 and can rotate around its own axis in guide seat 132;

[0140] Support base 134 is disposed at both ends of guide base 132, which confines the adjusting screw 133 in guide base 132 and can support the rotation of adjusting screw 133;

[0141] The sliding sleeve 135 is provided with an internal thread. The sliding sleeve 135 is threadedly connected to the adjusting screw 133. The sliding sleeve 135 is restricted from rotating in the guide seat 132. When the adjusting screw 133 rotates, the sliding sleeve 135 moves along the axis of the adjusting screw 133 in the guide seat 132.

[0142] A rotating shaft 116 (not shown in the figure) is disposed on the first side of the sliding sleeve 135. The second ends of the first support rod 106a and the second support rod 106b are both hinged to the rotating shaft 116. A sliding groove is provided on the left or right side of the guide seat 132. The rotating shaft 116 can extend from the sliding groove and be hinged to the first support rod 106a and the second support rod 106b. When the sliding sleeve 135 moves in the guide seat 132, the rotating shaft 116 moves along the sliding groove.

[0143] The adjusting screw 133 can be rotated clockwise or counterclockwise, and can move in different directions in the guide seat 132. When it moves away from the third support rod 106c, the first support rod 106a and the second support rod 106b can be unfolded relative to each other. When it moves towards the third support rod 106c, the first support rod 106a and the second support rod 106b can be folded relative to each other.

[0144] In one implementation, such as Figure 14 As shown, the locking device 107 also includes:

[0145] Rotate handle 131, which is fixedly connected to the first end of adjusting screw 133. Rotating handle 131 operates adjusting screw 133 to rotate. Rotating handle 131 is approximately Z-shaped. Rotating handle 131 rotates adjusting screw 133, causing adjusting screw 133 to rotate clockwise or counterclockwise.

[0146] Because the lane bracket 104b is equipped with two support plates that support the vehicle wheels, and both support plates need to be supported, the container 100 needs to be equipped with two sets of bracket support devices 105b to support the lane bracket 104b.

[0147] In one implementation, such as Figure 1 , Figure 3 As shown, two sets of bracket support devices 105b are symmetrically arranged in the container 100. A transverse connecting rod 108 is provided between the two sets of bracket support devices 105b. The two ends of the transverse connecting rod 108 are fixedly connected to the second support rod 106b of the two sets of bracket support devices 105b, respectively, and the connection can be fixed by welding. By setting the transverse connecting rod 108, the two sets of bracket support devices 105b can be opened and closed synchronously, providing more stable support for the lane bracket 104b and preventing the lane bracket 104b from tilting during lifting.

[0148] The two ends of the transverse connecting rod 108 can also be fixedly connected to the first support rod 106a of the two sets of bracket support devices 105b, or to the third support rod 106c, or to the locking device 107, for example, to the rotating shaft or sliding sleeve 112 in the locking device 107. These connection structures can all achieve the effect of improving the stability of the support of the two sets of bracket support devices 105b on the lane bracket 104b. It should be noted that if either the first support rod 106a or the second support rod 106b is located on the outer side, it is not suitable to connect the transverse connecting rod 108, because there may be mechanical interference when the bracket support device 105b is folded. The transverse connecting rod 108 is only suitable to be connected to the first support rod 106a or the second support rod 106b located on the inner side. Since the third support rod 106c and the locking device 107 have parts that do not overlap with other components, there is no mechanical interference problem when the transverse connecting rod 108 is connected to them when the bracket support device 105b is folded.

[0149] like Figure 1 , Figure 2 , Figure 18 As shown, an embodiment of the present invention also provides a container 100, including: the bracket support device 105b as described in any of the above embodiments.

[0150] During the raising of the lane bracket 104b, the bracket support device 105b unfolds accordingly, and the raised state of the lane bracket 104b is as follows: Figure 15 As shown, the bracket support device 105b is in the unfolded state at this time. During the descent of the lane bracket 104b, the bracket support device 105b folds down accordingly. The descent state of the lane bracket 104b is as follows. Figure 16 As shown, the bracket support device 105b is in a folded state at this time.

[0151] It should be noted that the bracket support device 105b can be used alone in the container 100, or it can be used simultaneously with the existing bracket support device 105a in the container 100. Figure 1 The container 100 is equipped with three sets of lane brackets 104b, and the second end of each of the three sets of lane brackets 104b uses two sets of bracket support devices 105b. Figure 18 The container 100 is equipped with three sets of lane brackets 104b. The second end of the lane bracket 104b near the front end uses two sets of bracket support devices 105b, while the second end of the lane brackets 104a located in the middle and near the rear end uses two sets of existing bracket support devices 105a. The structure of the bracket support device 105a can refer to the prior art and will not be described in detail here.

[0152] In one implementation, such as Figure 1 , Figure 18As shown, container 100 also includes:

[0153] The base frame assembly 101 has a front-end assembly 102 at its front end and a rear-end assembly 103 at its rear end. Both the front-end assembly 102 and the rear-end assembly 103 include two corner posts. The front-end assembly 102 and the rear-end assembly 103 can also be folded and unfolded. The unfolded state is as follows: Figure 15 As shown, the folded state is as follows Figure 16 As shown;

[0154] Multiple lane brackets 104b, with a first end of each lane bracket 104b hinged to a base frame assembly 101, and a second end of each lane bracket 104b hinged to the first end of a first support rod 106a of a bracket support device 105b. The hinge points are located at the bottom of the lane brackets 104b. Figure 15 As shown, a first ear seat 123 is provided at the hinge position to connect the first end of the first support rod 106a. By providing the first ear seat 123, it is convenient to set the connection hole and install the pin, so as to realize the hinge connection between the first end of the first support rod 106a and the lane bracket 104b.

[0155] When the second end of the lane bracket 104b is raised upward, the first support rod 106a and the second support rod 106b of the bracket support device 105b can be unfolded relative to each other. When the second end of the lane bracket 104b is lowered downward, the first support rod 106a and the second support rod 106b of the bracket support device 105b can be folded relative to each other.

[0156] In one implementation, such as Figure 1 , Figure 2 , Figure 18 As shown, the base frame assembly 101 includes: two bottom side beams 101b and multiple bottom cross beams 101a;

[0157] Bottom side beams 101b are arranged on both sides of the underframe assembly 101 along the length of the container 100, and the width of the lane bracket 104b is not greater than the distance between the two bottom side beams 101b.

[0158] The bottom crossbeam 101a is positioned between the two bottom side beams 101b along the width direction of the container 100. The second support rod 106b and the third support rod 106c of the bracket support device 105b are respectively hinged to the bottom crossbeam 101a, with the hinged position located between the two bottom side beams 101b.

[0159] like Figure 15As shown, a second lug 124 is provided at the hinge position between the second support rod 106b and the bottom crossbeam 101a, and a third lug 125 is provided at the hinge position between the third support rod 106c and the bottom crossbeam 101a. Both are located between the two bottom side beams 101b, so that the entire bracket support device 105b is located between the two bottom side beams 101b. Whether folded or unfolded, it does not occupy space outside the two bottom side beams 101b, reducing the impact of the bracket support device on the container loading space. By providing the second lug 124, it is convenient to set the connection hole and install the pin to achieve the hinge connection between the first end of the second support rod 106b and the bottom crossbeam 101a; by providing the third lug 125, it is convenient to set the connection hole and install the pin to achieve the hinge connection between the first end of the third support rod 106c and the bottom crossbeam 101a.

[0160] In one implementation, such as Figure 1 , Figure 18 As shown, a pull ring 127 is provided at the top of the second end of the lane bracket 104b. The second end of the lane bracket 104b is raised and lowered by operating the pull ring 127. The pull ring 127 and the lane bracket 104b can be fixed by welding.

[0161] In one implementation, such as Figure 1 , Figure 15 , Figure 18 As shown, the lane bracket 104b is also provided with a movable stop 128, which is used to block the wheels of the vehicle. The position of the stop 128 on the top of the lane bracket 104b can be adjusted according to the different vehicles being loaded to accommodate vehicles of different lengths.

[0162] In one implementation, such as Figure 15 , Figure 16 As shown, a support block 126 is also provided on the bottom beam 101c. The support block 126 is located on the side of the bottom beam 101c near the lane bracket 104b. The top of the support block 126 is lower than the top of the bottom beam 101c, forming a limiting step. When the lane bracket 104b needs to be laid flat for unloading, its lower front end can abut against the bottom beam 101c and the support block 126 to achieve horizontal limiting.

[0163] In one implementation, such as Figure 17As shown, a first locking assembly 129 is also provided on the bottom beam 101c to lock the lane bracket 104b after it has landed, preventing the lane bracket 104b from shaking randomly after landing. The first locking assembly 129 is located on the top of the bottom beam 101c and includes components such as a lock body 129a, a locking tongue 129b, and a locking spring 129c. The locking tongue 129b passes through the lock body 129a, and the locking spring 129c is located inside the lock body 129a and sleeved on the locking tongue 129b. The front end of the locking tongue 129b is pointed, and it can automatically lock with the front end of the locking tongue 129b when the lane bracket 104b lands on the bottom beam 101c. A handle 129d is provided at the tail end of the locking tongue 129b. By pulling the handle 129d, the locking tongue 129b can be retracted, thereby unlocking the locking tongue 129b from the lane bracket 104b.

[0164] According to a bracket support device and a container of the present invention, the bracket support device can be unfolded for installation and folded for storage in the internal space between the lane bracket and the main structure of the container, reducing the impact of the bracket support device on the container loading space. The bracket support device does not rely on the bottom side beam of the container for fixation, making the installation position more flexible. At the same time, the bracket support device is provided with three support rods, shortening the length of each support rod, thereby reducing the operating angle of the support rods and the travel of the locking device, further saving the space required for installation in the container and reducing the impact of the bracket support device on the container loading space.
