[0071] As Figure 1 and 2As shown, the utility model discloses a gantry container. The gantry container comprises a lower platform 110, an end frame 120, an upper platform 130 and a scissor assembly 140. The end frame 120 is arranged at the end of the lower platform 110 and can rotate relative to the lower platform 110 between a folded position and an unfolded position. The end frame 120 comprises two corner columns 121. The upper platform 130 is located above the lower platform 110. The scissor assembly 140 is connected to the lower platform 110 and the upper platform 130 respectively. When the end frame 120 is in the unfolded position, the upper platform 130 can move along the corner column 121 between a lowered position and a raised position relative to the lower platform 110. When the upper platform 130 is in the lowered position, the scissor assembly 140 is in a compressed state, and when the upper platform 130 is in the raised position, the scissor assembly 140 is in an open state to support the upper platform 130.

[0072] According to the gantry container of the utility model, the upper platform 130 can be adjusted at different heights between the lowered position and the raised position to adapt to loading different models of vehicles, and when the upper platform 130 is in the lowered position, it is convenient for loading and unloading vehicles. After vehicle transportation is completed, the upper platform 130 can be adjusted to the lowered position, and the end frame 120 is adjusted to the folded position, so that the occupied space of the gantry container is greatly reduced, so that multiple gantry containers can be stacked together for transportation, the cost of empty container transportation is reduced, and the efficiency of empty container transportation is improved.

[0073] The gantry container is provided with at least one scissor assembly 140 on each side in the width direction of the gantry container. Preferably, two scissor assemblies 140 are arranged on each side, i.e. a total of four scissor assemblies 140. Specifically, as shown, Figure 3 The scissor assembly 140 comprises a first arm frame 141 and a second arm frame 144 that can rotate relative to each other. That is, the first arm frame 141 and the second arm frame 144 are connected by an intermediate pin 147 (for example, configured as an X shape), and both can rotate around the intermediate pin 147. The first arm frame 141 has a first end 142 connected to the lower platform 110 and a second end 143 connected to the upper platform 130. The second arm frame 144 has a third end 145 connected to the lower platform 110 and a fourth end 146 connected to the upper platform 130.

[0074] In one embodiment, the first end 142 and the second end 143 of the first boom 141, and the third end 145 and the fourth end 146 of the second boom 144 are all movable along the length of the container on the platform, so that the scissor lift assembly 140 can switch between a compressed state and an open state as the upper platform 130 moves, and the scissor lift assembly 140 as a whole can move along the length of the container on the platform. Preferably, the ends of the first boom 141 and the second boom 144 located on one side along the length of the container on the platform are movable, while the ends on the other side are not movable along the length of the container on the platform, thereby preventing the scissor lift assembly 140 as a whole from moving arbitrarily relative to the lower platform 110 and the upper platform 130, ensuring stable support. For example, the first end 142 of the first boom 141 and the fourth end 146 of the second boom 144 can move along the length of the container on the platform, or the second end 143 of the first boom 141 and the third end 145 of the second boom 144 can move along the length of the container on the platform.

[0075] In such Figure 3 In the illustrated embodiment, the outer end of the scissor lift assembly 140 along the length of the container rack is movable along the length of the container rack, while the inner end is hinged to the lower platform 110 and the upper platform 130 respectively for rotation about a pin or shaft. Specifically, the lower platform 110 includes a lower side beam 114 extending along the length of the container rack. The upper platform 130 includes an upper side beam 134 extending along the length of the container rack. Both the lower side beam 114 and the upper side beam 134 are provided with a groove 161. The second end 143 of the first boom 141 and the third end 145 of the second boom 144 are provided with pulleys 162, which are slidable along the grooves 161. The first end 142 of the first boom 141 is rotatably connected to the lower platform 110. The fourth end 146 of the second boom 144 is rotatably connected to the upper platform 130. Thus, when the upper platform 130 is moved between the lowered position and the raised position by the forklift, the pulleys 162 of the second end 143 and the third end 145 move along the slide 161, so that the scissor fork assembly 140 switches between the compressed state and the open state.

[0076] Further, the gantry container further comprises a limiting part 163 for abutting against the free end of the scissor assembly 140 to fix the scissor assembly 140 so that the upper platform 130 is stabilized at a set position. The limiting part 163 is detachably arranged in a sliding groove 161 of at least one of the lower side beam 114 and the upper side beam 134. For example, the limiting part 163 has a limiting hole, and the sliding groove 161 is provided with a sliding groove hole, when the limiting hole and the sliding groove hole are aligned, a limiting pin can be inserted through the limiting hole and the sliding groove hole to fix the limiting part 163 relative to the sliding groove 161. The sliding groove 161 can also be provided with a plurality of sliding groove holes along the length direction of the gantry container, so that the position of the limiting part 163 in the sliding groove 161 can be adjusted as needed to abut against the scissor assembly 140 at different positions, thereby supporting the upper platform 130 at different heights.

[0077] When the scissor assembly 140 is in the open state, the limiting part 163 abuts against the pulley 162 to prevent the pulley 162 from sliding. Specifically, when the forklift is used to move the upper platform 130 to a set height, the limiting part 163 is placed in the sliding groove 161 to abut against the corresponding position of the pulley 162, and the limiting pin is inserted, so that the scissor assembly 140 is kept in the open state to support the upper platform 130. In Figure 3 In the embodiment shown, since the pulley 162 is arranged at the outer end of the scissor assembly 140 along the length direction of the gantry container, the limiting part 163 is arranged outside the pulley 162 along the length direction of the gantry container. When it is needed to move the upper platform 130 to a lowered position or to adjust the height of the upper platform 130, the limiting pin can be pulled out and the limiting part 163 can be removed, and then the forklift is used to move the upper platform 130.

[0078] The limiting part 163 can be configured as a cubic limiting block, or can be configured in other shapes. For example, the surface of the limiting part 163 for abutting against the pulley 162 is configured as an arc shape to match the shape of the pulley 162, so as to more evenly distribute the force and prolong the service life.

[0079] As Figure 1 shown, the end frame 120 further comprises an end cross beam 126 extending along the width direction of the gantry container and connected to the top end of the two corner columns 121. When the end frame 120 is in the unfolded position, the corner column 121 can be perpendicular to the lower platform 110 and the upper platform 130. As Figure 1 and Figure 4As shown, the corner post 121 is equipped with a slide rail 122, which can be attached to the surface of the corner post 121 body. The upper platform 130 is equipped with a sliding part 131, which is located at the end of the upper platform 130 along the length of the container on the rack. The sliding part 131 can slide along the slide rail 122 to guide the movement of the upper platform 130, allowing the upper platform 130 to move up and down more stably. At the same time, the structure of the sliding part 131 and the slide rail 122 can maintain the stability of the upper platform 130 during the transportation of the container on the rack.

[0080] The sliding part 131 is detachably disposed on the upper platform 130. For example, as Figure 5 As shown, a sliding mounting plate 132 is provided at the end of the upper platform 130, and the sliding part 131 is detachably mounted to the sliding mounting plate 132 via a sliding pin 133. Since the sliding part 131 is a wear part, it can be removed and replaced after a certain period of use.

[0081] like Figure 4 As shown, the lower platform 110 is provided with a base 111, which is fixedly connected to and perpendicular to the body of the lower platform 110. Angle posts 121 are rotatably connected to the base 111. For example, the base 111 is provided with a rotation shaft 113 extending in the width direction, around which the angle posts 121 can rotate. The rack container also includes a retaining pin 112. The base 111 has a retaining hole, and the angle posts 121 have a locking hole. When the end frame 120 is in the unfolded position, the retaining hole and the locking hole are aligned, and the retaining pin 112 passes through the retaining hole and the locking hole in the width direction of the rack container to prevent the angle posts 121 from rotating. When it is necessary to rotate the end frame 120 to the folded position, the retaining pin 112 can be removed to rotate the angle posts 121 around the rotation shaft 113. Figure 2 As shown, when the upper platform 130 is in the lowered position, the sliding part 131 is located in the base 111, that is, the sliding part 131 is disengaged from the corner post 121, so that the end frame 120 can rotate to the folded position.

[0082] like Figure 4As shown, the corner post 121 includes a connecting post 123 and a telescopic post 124. The connecting post 123 is rotatably connected to the lower platform 110 (e.g., base 111), and a slide rail 122 can be disposed on the connecting post 123. The telescopic post 124 is movable relative to the connecting post 123 along the extension direction of the corner post 121. The connecting post 123 can be constructed as a hollow sleeve, and the telescopic post 124 is disposed within the connecting post 123. The connecting post 123 and the telescopic post 124 have corresponding through holes, and when the through holes are aligned, inserting a positioning pin 125 can fix the telescopic post 124 relative to the connecting post 123. At least one of the connecting post 123 and the telescopic post 124 can be provided with multiple through holes along the extension direction of the corner post 121 to adjust the length of the telescopic post 124 extending out of the connecting post 123 as needed. Since railway transportation has height restrictions, after loading the vehicle, the positioning pin 125 can be pulled out to lower the telescopic post 124, thereby meeting the transportation requirements.

[0083] The top of the corner post 121 (e.g., the top of the telescopic post 124) is provided with a top corner piece 127, and the bottom of the lower platform 110 (e.g., the bottom of the base 111) is provided with a bottom corner piece 115. The top corner piece 127 and the bottom corner piece 115 can be standard container corner pieces to enable connection with container spreaders such as lifting machinery (e.g., gantry cranes, reach stackers) to complete the lifting operation.

[0084] like Figure 1 and Figure 3 As shown, the rack container also includes a movable platform 150. The movable platform 150 is movably disposed at the ends of the lower platform 110 and / or the upper platform 130 along the length of the rack container, between a retracted position and an extended position. In the illustrated embodiment, the movable platform 150 can be disposed at both ends of the lower platform 110 and the upper platform 130. Thus, when the movable platform 150 is in the retracted position, the length of the rack container is 40 feet, and the upper platform 130 and the lower platform 110 can each load two cars; when the movable platform 150 is in the extended position, the length of the rack container becomes 50 feet, and the upper platform 130 and the lower platform 110 can each load three cars, increasing carrying capacity.

[0085] The specific loading process is as follows: the end frame 120 is rotated from the folded position to the unfolded position by using a forklift and is fixed by using the fixing pin 112, the telescopic column 124 is pulled up to the highest position and is fixed by using the positioning pin 125, the movable plate 150 is pulled out to the extended position, the car is driven into the upper platform 130 in sequence and is fixed, then the upper platform 130 is lifted to the set lifting position by using the forklift, and the scissor assembly 140 is locked by the limiting part 163 to support the upper platform 130. The remaining cars are driven into the lower platform 110 in sequence and are fixed, thereby the loading of the cars is completed. After the loading of the cars is completed, the existing hoisting tool (a gantry crane, a front lifting crane, etc.) in the freight yard can be used to hoist the rack container to a container flat car or a truck for transportation. If there is a height limit requirement such as railway transportation, the positioning pin 125 is pulled out after loading, so that the height of the telescopic column 124 is lowered. After arriving at the target location, the rack container can be changed into the folded state shown in the figure by the operation opposite to the above steps, and the multiple rack containers are stacked.
