Detailed Description

The invention will be better explained by the following detailed description of the embodiments with reference to the drawings. References herein to the terms "upper", "lower", "bottom" and the like are made by way of example to figures 1, 3 to 12, and reference is also made to the orientation of the container when it is actually transported.

Example 1

Referring to fig. 1 to 3, the present embodiment provides a lateral bracing device for cargo within a container, i.e. providing lateral bracing of the cargo 3 from the inside of the cargo 3 such that the cargo 3 rests on the side walls 73 of the container 7 or on vertical beams 74 supported on the side walls 73 of the container 7.

In this embodiment, the lateral jacking device includes two sets of jacking assemblies.

Each top support assembly comprises two vertical support beams 1, the vertical support beams 1 are supported on the floor 71 in the container 7, the two vertical support beams 1 are used for being placed between two cargoes 3, namely, each vertical support beam 1 is placed on the inner side of a corresponding one of the cargoes 3, and the outer side of the cargoes 3 is the side wall 73 of the container 7. The vertical support beam 1 has a vertical support surface 11 facing the cargo 3 and extending along the length direction of the vertical support beam 1 itself, and the vertical support surface 11 may have a length smaller than the vertical support beam 1, or the vertical support surface 11 may have a length equal to the length of the vertical support beam 1, because the top end, the bottom end, and other positions of the vertical support beam 1 may also need to be provided with structures having other functions, or a plurality of intermittent vertical support surfaces 11 may be provided. The above mentioned vertical support surface 11 is intended to rest against the cargo 3, such that the position of the force applied by the vertical support beam 1 is the vertical support surface 11 when the load 3 is pressurized. Thus, the lateral jacking device focuses on a wide range of force applied in the height direction of the cargo 3, and preferably provides support from the bottom end to the top end of the cargo 3 at a suitable position, and the support provided by the local small range of force applied is significantly more stable relative to the timber.

Wherein the shape of the vertical support surface 11 preferably matches the shape of the portion of the inner side of the cargo 3 facing the vertical support surface 11 to provide a more secure support for the cargo 3, e.g. typically the inner side of the cargo 3 is planar, then the vertical support surface 11 is planar. Of course, the present invention is not limited thereto, as long as the vertical support surface 11 is ensured to provide a large area of contact support in the height direction of the cargo 3, and the large area of contact support is not required in the length direction of the cargo 3, i.e., the width direction of the vertical support surface 11, i.e., the extending direction of the side wall 73 of the container 7 against which the cargo 3 is pressed, and thus the shape of the vertical support surface 11 may not be completely matched with the shape of the portion of the inner side surface of the cargo 3 facing the vertical support surface 11.

The profile of the vertical support surface 11 may be rectangular, or may be shaped, but the length of the vertical support surface 11 (i.e., the dimension along the height direction of the cargo 3) should be significantly larger than the width thereof, which is called as "vertical support beam 1" and "vertical support surface 11". For example, the support beam may be formed in the shape of a channel, the vertical support surface 11 has a width of 100mm and the supportable cargo has a height of 2440mm, i.e., the length of the vertical support surface may be about 2400mm, whereby the length of the vertical support surface is 20 times the width thereof, which is, of course, merely an example and not limiting of the invention.

Wherein the vertical support beam 1 may comprise a plurality of vertical support surfaces 11, the plurality of vertical support surfaces 11 may be spaced apart in the length direction and/or the width direction of the vertical support beam 1, in other words, only one vertical support surface 11 from top to bottom in the vertical support beam 1 is not required. It is also within the scope of the invention for the plurality of vertical support surfaces 11 to together provide a contact support of a larger area in the height direction of the load 3 as a whole.

Further, in the case where the vertical support beam 1 has a plurality of vertical support surfaces 11 aligned in the longitudinal direction of the vertical support beam 1 itself, the sum of the lengths of the plurality of vertical support surfaces 11 aligned in the longitudinal direction of the vertical support beam 1 itself is 90% or more of the height of the cargo 3, it should be noted that the ratio is not necessarily 100% or less in other embodiments, for example, the ratio may be higher than 100% when the top end of the vertical support beam 1 is higher than the top end of the cargo 3. In the case of a vertical support beam 1 having only one continuous vertical support surface 11 along its own length, the length of the vertical support surface 11 is more than 90% of the height of the cargo 3, it should be noted that in other embodiments the ratio is not necessarily less than 100%, for example, when the top end of the vertical support beam 1 is higher than the top end of the cargo 3, the ratio may be higher than 100%. In this way, the vertical support beam 1 is more stable for supporting the cargo 3. In this embodiment, the vertical support beam 1 in the lateral jacking device is supported by the floor 71 of the container 7, and is more stable than the manner of using the side walls and the top wall of the container as supporting points.

The vertical support beam 1 may, among other things, comprise a rigid beam covered with a flexible layer, such as rubber, at the portions of the beam that need to be in contact with the cargo 3. The outer surface of the flexible layer constitutes the above mentioned vertical support surface 11. In this way, the vertical support beam 1 can be prevented from damaging the cargo when transporting fragile cargo such as glass.

Each jacking assembly further comprises two telescopic jacking members 2, the telescopic jacking members 2 being members for providing pressure to the vertical support beams 1 towards the cargo 3. The telescopic jacking pieces 2 are arranged between the two vertical supporting beams 1, the two telescopic jacking pieces 2 are vertically arranged at intervals, preferably the two telescopic jacking pieces 2 respectively correspond to the upper part and the lower part of the vertical supporting beam 1, the telescopic jacking piece 2 positioned above in the two telescopic jacking pieces 2 is arranged at a position 200-300mm lower than the top surface of the goods 3, the telescopic jacking pieces 2 positioned below in the two telescopic jacking pieces 2 are arranged at a position 0-300mm away from the floor of the container, so that the stress of the vertical supporting beam 1 after jacking is relatively uniform, the acting force is applied to the goods 3 uniformly as much as possible, and the support to the goods 3 is also more stable. Of course, in this embodiment, two telescopic jack-up members 2 are taken as an example, and in other embodiments of the present invention, three or more telescopic jack-up members 2 may be provided, i.e., other telescopic jack-up members 2 may be provided between the upper telescopic jack-up member 2 and the lower telescopic jack-up member 2 in this embodiment. Of course, a telescopic jack-up 2 can also be provided in case the vertical support beam 1 can be stably supported.

The telescopic propping piece 2 is rod-shaped, and the telescopic propping piece 2 can be in telescopic switching between a propping state and a releasing state.

When the telescopic jack 2 is in the jack state, two ends of the telescopic jack 2 (i.e., two outermost ends of the telescopic jack 2 in the telescopic direction thereof may be referred to as telescopic ends) respectively press two vertical support beams 1 against the cargo 3 on both sides, and the cargo 3 is pressed against the side wall 73 of the container or the vertical beam 74 on the inner side of the side wall 73 of the container.

When the telescopic supporting piece 2 is in a release state, the length of the telescopic supporting piece 2 is smaller than that of the supporting state, and the jacking of the two vertical supporting beams 1 to the goods 3 can be relieved.

Preferably, the minimum length of the telescopic jack 2 is smaller than the length of the telescopic jack 2 in the released state, so as to facilitate disassembly and not to reach the limit state to be damaged; the maximum length of the telescopic jack 2 is equal to or longer than the length of the telescopic jack 2 in the jack state, preferably, is greater than the maximum length so as not to reach the limit state to be damaged.

Thus, the lateral jacking device of the present embodiment can provide stable fixation for the cargo 3 in the container to prevent it from toppling over, and since the vertical support beam 1 is a force application member for the cargo 3 and the telescopic jacking piece 2 is telescopic, it is applicable to the cargo 3 of various heights and various thicknesses and can be repeatedly used. And under the condition that the lengths of cargoes 3 are different, a plurality of groups of jacking components can be arranged selectively, so that the lateral jacking device of the embodiment is also suitable for repeated use of cargoes 3 with various lengths. The container using the lateral shoring device has the advantages that the cargo 3 is reinforced and stable, the transportation is safe, and the transportation cost is reduced. In addition, when the lateral jacking device is installed, workers can operate the lateral jacking device by standing on the floor of the container without auxiliary tools such as a stool, and the lateral jacking device is safer and more convenient to operate.

Further, in the present embodiment, the telescopic jacking member 2 includes a sleeve 21 and two screw rods 22 screwed at both ends of the sleeve 21, and the ends of the two screw rods 22 away from the sleeve 21 constitute the above telescopic ends for directly or indirectly jacking up the vertical support beams 1 (through other structures), that is, opposite ends of the two screw rods 22 are used for transmitting the force to the vertical support beams 1 on both sides. The rotation of the sleeve 21 can drive the two screws 22 to extend and retract simultaneously, i.e., for example, when the sleeve 21 is rotated clockwise, the two screws 22 extend simultaneously to lengthen the whole telescopic jack 2, and when the sleeve 21 is rotated counterclockwise, the two screws 22 lock in simultaneously to shorten the whole telescopic jack 2.

In this embodiment, the end of the screw rod is directly used as the telescopic end, but other structures are added on the end of the screw rod to contact the vertical support beam 1 in other embodiments.

Wherein nuts 26 are fixed at both ends of the sleeve 21, and the sleeve 21 and the nuts 26 are fixed together by welding, for example. The two screws 22 are screwed with the two nuts 26, respectively, and the rotation directions of the two screws 22 are opposite, so that when the sleeve 21 is rotated, the two screws 22 move simultaneously into the sleeve 21 or simultaneously out of the sleeve 21. Of course, the present invention is not limited to this, and the inner peripheral walls of both ends of the sleeve 21 may be provided with female screws having opposite directions to the screw shafts 22 on both sides, instead of the nuts 26, so that the screw shafts 22 can be extended and retracted simultaneously. As described above, the telescopic jack 2 is preferably constructed in a laterally symmetrical manner. Of course, the telescopic jack 2 may be telescopic only by one stage, i.e. one of the two screws 22 is omitted, but the telescopic efficiency is low and the installation speed is low. More than two stages (including two stages) of telescoping are preferably employed.

Further, in the present embodiment, two jack-up assemblies are provided, but not limited thereto, the more jack-up assemblies are provided, the more firmly the support is. Preferably, when n number of the top support assemblies are provided, the distance from the top support assemblies at the two outermost ends to the same side end of the cargo 3 is 1/(n+1) or less of the length of the cargo, and the distance between the adjacent two top support assemblies is 1/(n+1) or more of the length of the cargo, where n is an integer of 1 or more. For example, when two jack-up assemblies are provided, the distance from the jack-up assembly located in front to the front end of the cargo 3 is 1/3 or less of the length of the cargo, the distance from the jack-up assembly located in rear to the rear end of the cargo 3 is 1/3 or less of the length of the cargo, and the distance between two adjacent jack-up assemblies is 1/3 or more of the length of the cargo; when the four top support assemblies are arranged, the distances from the forefront top support assembly and the rearmost top support assembly of the four top support assemblies to the front end and the rear end of the cargo 3 respectively are less than or equal to 1/5 of the length of the cargo, and the distance between every two adjacent top support assemblies of the four top support assemblies is greater than or equal to 1/5 of the length of the cargo.

Further, in the case of providing two jack assemblies, the telescopic jack members 2 in the two jack assemblies are provided at the same height, specifically, if each jack assembly has only one telescopic jack member 2, then the two telescopic jack members 2 are provided at the same height; if each supporting component is provided with a plurality of telescopic supporting pieces 2, the telescopic supporting pieces 2 in two adjacent supporting components are correspondingly equal in height. As shown in fig. 1 to 3, in the present embodiment, each of the jack assemblies has two telescopic jack members 2, and the upper telescopic jack member 2 of one jack assembly is equal in height to the upper telescopic jack member 2 of the other jack assembly, and the lower telescopic jack member 2 of one jack assembly is equal in height to the lower telescopic jack member 2 of the other jack assembly.

Further, a plurality of handles 25 may be provided on the sleeve 21, the plurality of handles 25 being evenly distributed along the sleeve 21. In the present embodiment, 4 handles 25 are provided, which are evenly distributed along the circumferential direction of the sleeve 21, i.e., one handle 25 is provided every 90 °. When two telescopic propping pieces 2 positioned at the same height in two adjacent propping assemblies are in a propping state, the two telescopic propping pieces 2 with the same height are fixed through a locking piece 6 so as to prevent the two telescopic propping pieces from rotating.

In this embodiment, the locking member 6 is a tightening member, and at this time, when the telescopic jack-up member 2 is developed from the release state to the jack-up state, it is ensured that two handles 25 on opposite sides of two telescopic jack-up members 2 located at the same height in two adjacent jack-up assemblies are both located at the horizontal position while providing a proper jack-up force for the vertical support beam 1, and the handles 25 on opposite sides of the two telescopic jack-up members 2 located at the horizontal position are connected by the tightening member. In this way, setting up handle 25 makes things convenient for the rotatory sleeve 21 of operator on the one hand, and on the other hand accessible taut piece is with two connection of medium height of two jack-up subassemblies, prevents that two sleeves 21 from rotating for whole jack-up device is more firm, avoids leading to the reinforcement inefficacy because of the rotation of sleeve 21. The tightening piece can be iron wires, steel wires, binding bands and the like, and two ends of the tightening piece are tied on the handle 25.

Of course, the locking member 6 may be a locking member in addition to the tightening member, at this time, when the telescopic jack 2 is developed from the release state to the jack state, it is ensured that two telescopic jacks 2 located at the same height in two adjacent jack assemblies are both provided with a handle 25 at a vertical position (may be located above or below the sleeve 21) under the condition of providing a proper jack force for the vertical support beam 1, and the two handles 25 are equally high, and two ends of the locking member are inserted into the two handles 25 located at the same height and at the vertical position on the two telescopic jacks 2 at the same height, so as to play a role in preventing the sleeve 21 from rotating. The locking piece can be a rod-shaped object (such as an iron rod or a wood rod).

The number of handles 25 is not limited to 4, but may be 6, 8, or the like. Meanwhile, since the handles 25 are required to be in the horizontal position or the vertical position when the telescopic jack 2 is in the jack state, the number of the handles 25 is also required to be designed in combination with the telescopic travel of the telescopic jack 2, for example, in this embodiment, the distance of extension or retraction of the screw 22 is 2mm every 90 ° of rotation of the sleeve 21, and it is easy to satisfy that the handles 25 are in the horizontal position or the vertical position when the telescopic jack 2 is in the jack state by fine adjustment.

Further, the two telescopic ends of the telescopic jack-up member 2 may be non-detachably connected to the vertical support beam 1, or may be detachably connected, and more preferably, the detachable and height-variable connection of the telescopic jack-up member 2.

Referring to fig. 4, in the present embodiment, the telescopic jack-up member 2 and the vertical support beam 1 are detachably connected, and the connection structure of the two includes a first insertion structure 23 provided at the telescopic end of the telescopic jack-up member 2 and a second insertion structure 12 provided at the vertical support beam 1, the first insertion structure 23 being detachably inserted with the second insertion structure 12 and enabling the telescopic jack-up member 2 and the vertical support beam 1 to be relatively fixed when inserted, such fixing means restricting the movement of the telescopic end of the telescopic jack-up member 2, in particular restricting the rotation and upward and downward movement of the telescopic end of the telescopic jack-up member 2. Preferably, a plurality of second plugging structures 12 are arranged on the vertical supporting beam 1 along the length direction thereof, and the plurality of second plugging structures 12 are distributed on the whole length of the vertical supporting beam 1, so that one or a plurality of telescopic supporting pieces 2 can be installed at proper positions according to the needs, the installation positions are variable, and the heights of the telescopic supporting pieces 2 can be changed.

Preferably, as shown in fig. 4, the first plugging structure 23 is a rectangular tube, and is disposed at the telescopic end of the telescopic jack 2, in this embodiment, the end of the screw 22 far away from the sleeve 21; the lateral direction of the vertical supporting beam 1 is extended with a bulge, and the second inserting structure 12 is a rectangular slot arranged in the bulge. It can be seen that the plugging direction of the first plugging structure 23 and the second plugging structure 12 is the telescoping direction of the telescoping jack 2. After the rectangular pipe is inserted into the rectangular slot, on one hand, the telescopic jacking piece 2 is limited by the vertical supporting beam 1 in the vertical direction, and on the other hand, the telescopic jacking piece 2 cannot rotate relative to the vertical supporting beam 1. Thus, it is more stable. The rectangular tube can be replaced by other polygonal tubes, elliptic tubes and tubes with the outer edge of the cross section in a shape consisting of an arc and a straight line, so long as the rectangular tube can be prevented from rotating. Of course, the first insertion structure 23 is not limited to a tube, and a solid member may be, for example, an iron piece, an iron block, or the like. The second insertion structure 12 is not limited to the insertion groove provided on the projection, but may be an insertion groove recessed in the vertical support beam 1, or the like. Of course, the first plug structure 23 and the second plug structure 12 may be interchanged. In summary, it is preferred that one of the first and second plug structures 23, 12 is a plug having a polygonal cross section (a cross section perpendicular to the plug structure) and the other is a socket in shape-fitting with the plug. Among them, the polygon is more preferably rectangular.

Of course, the present invention is not limited thereto, and for example, as shown in fig. 5, the connection structure of the telescopic jack-up member 2 and the vertical support beam 1 may alternatively include a first mounting structure 24 provided at the telescopic end of the telescopic jack-up member 2, a second mounting structure 13 provided at the vertical support beam 1, and a mounting structure connection member 4, the mounting structure connection member 4 detachably connecting the first mounting structure 24 and the second mounting structure 13, the telescopic jack-up member 2 and the vertical support beam 1 being relatively fixed when the mounting structure connection member 4 connects the first mounting structure 24 and the second mounting structure 13 together, such fixing means restricting the movement of the telescopic end of the telescopic jack-up member 2, in particular including restricting the rotation, upward and downward movement of the telescopic end of the telescopic jack-up member 2. The first mounting structure 24 may be a through hole at the telescopic end of the telescopic supporting member 2, the second mounting structure 13 may be two tabs horizontally extending from the side wall of the vertical supporting beam 1, the tabs are provided with through holes, and the mounting structure connecting member 4 is a pin shaft, and the pin shaft sequentially passes through the through hole of the upper tab, the through hole of the telescopic supporting member and the through hole of the lower tab and is supported on the upper tab. The lug may be two iron sheets separately connected to the vertical support beam 1, or may be a U-shaped member connected to the vertical support beam 1.

In summary, the first and second plugging structures or the first and second mounting structures enable the connection structure of the telescopic jack-up member 2 and the vertical support beam 1 to be detachable, and the telescopic jack-up member 2 and the vertical support beam 1 are relatively fixed when connected, and the fixing limits the movement of the telescopic end of the telescopic jack-up member 2, in particular, limits the rotation and the upward and downward movement of the telescopic end of the telescopic jack-up member 2.

Of course, in other embodiments, the telescoping end of the telescoping jack-up member 2 may be non-detachably connected to the vertical support beam 1, at which point the ease of installation may be less than the detachable connection.

Referring to fig. 6, a lateral fixing structure is provided on the vertical support beam 1, which is provided on a side of the vertical support beam 1 facing the adjacent top support assembly. The lateral fixing structures of the same-side vertical supporting beams 1 in two adjacent top support assemblies are connected through lateral connecting pieces 5. This can improve the stability of the vertical support beam 1 from being inclined forward or backward, wherein the forward and backward direction is the arrangement direction of the plurality of top support assemblies. In this embodiment, the lateral fixing structure is a socket, and the lateral connecting member 5 is a U-shaped rod, and two ends of the U-shaped rod are respectively inserted into opposite sockets of the same-side vertical support beam 1 in the two adjacent top support assemblies. Of course, in other embodiments, the lateral fixing structure may be an annular member, the lateral connecting member 5 is a pull rope, and two ends of the pull rope are respectively fixed with the annular members opposite to the vertical supporting beams 1 on the same side in the two adjacent top supporting assemblies. This thereby allows two adjacent vertical support beams 1 to be connected together, providing stability of the overall lateral jacking device.

Referring to fig. 7, the bottom ends of the vertical support beams 1 are directly or indirectly fixed to the floor 71 of the container to increase the stability of the vertical support beams 1. In this embodiment, the bottom end of the vertical support beam 1 is provided with a clamping groove 14, the floor 71 of the container is fixed with a bottom beam 72, the goods 3 is supported on the bottom beam 72 on the floor 71 of the container, and the clamping groove 14 of the vertical support beam 1 is also supported on the bottom beam 72, so that the vertical support beam 1 will not shake. Since the cargo 3 is supported on the bottom beams 72 on the floor 71 of the container, there is a gap between the bottom surface of the cargo 3 and the floor 71 of the container, the bottom ends of the vertical support beams 1 laterally protrude out of the protruding members 15, and the protruding members 15 are adapted to be inserted into the gap between the bottom surface of the cargo 3 and the floor 71 of the container, preventing the vertical support beams 1 from moving upward. In this way, the stability of the vertical support beam 1 is increased.

Of course, the invention is not limited to the indirect fixing between the bottom end of the vertical support beam 1 and the floor 71 of the container by means of the engagement of the clamping groove 14 and the bottom beam 72 in combination with the protruding elements 15 on the vertical support beam 1, but in other embodiments, the bottom end of the bottom beam 72 may be fixed directly (e.g. with screws) to the floor 71 of the container. Alternatively, the bottom beams 72 may be replaced with bottom supports that are secured to the floor 71. The protruding member 15 may be a plate member, a rod member or a pipe member. If the protruding member 15 is made of hard material such as metal (e.g. steel, iron), the protruding member 15 is coated with flexible material (e.g. rubber) to prevent damage to the goods, especially when the goods are fragile articles such as glass.

Under the condition that the length of the vertical supporting beam 1 is large, the arrangement of the clamping groove 14 and the screw cannot completely avoid the vertical supporting beam 1 from tilting forwards or backwards under certain transportation conditions, so that the stability of the vertical supporting beam 1 and the overall stability of the lateral supporting device can be improved by combining the use of the lateral fixing structure.

In the present embodiment, the vertical support beam 1 and the telescopic roof support 2 are preferably made of metal or alloy.

The method for reinforcing the cargo in the container by adopting the lateral jacking device is described as follows:

In reinforcing the cargo 3, for each jacking assembly:

s1.1, placing two vertical support beams 1 on the inner sides of two cargos 3 in a container respectively, wherein the vertical support beams 1 are supported on bottom beams 72 on the floor 71 of the container through clamping grooves 14, and protruding pieces 15 are inserted into gaps between the bottom surfaces of the cargos 3 and the floor 71 of the container and are positioned between the two bottom beams 72;

S1.2, connecting the telescopic end of the telescopic supporting piece 2 with the vertical supporting beam 1, namely adjusting the length of the telescopic supporting piece 2 to enable the telescopic end to be connected with the vertical supporting beam 1. At this time, the telescopic jack-up member 2 has not yet acted as a jack-up to the vertical support beam 1, so the telescopic jack-up member 2 is in a released state, in this embodiment, the first plugging structure 23 of the telescopic jack-up member 2 is plugged into the second plugging structure 12 of the vertical support beam 1 (for example, the first mounting structure and the second mounting structure are connected by the mounting structure connector as shown in fig. 5) by referring to fig. 4, and step S1.2 is omitted when the telescopic jack-up member 2 is connected to the vertical support beam 1 itself;

S1.3, the telescopic jacking piece 2 is switched from a release state to a jacking state, specifically, the sleeve 21 is rotated to enable the two lead screws 22 to extend, and at the moment, the two vertical supporting beams 1 are respectively jacked on cargoes 3 on two sides.

After the goods are reinforced by the two adjacent top support assemblies, the step of fixing the two adjacent top support assemblies is executed:

S1.4, fixing two telescopic jacking pieces 2 with medium heights in two adjacent jacking assemblies by using a locking piece 6, and connecting a lateral fixing structure of a same-side vertical supporting beam 1 in the two adjacent jacking assemblies by using a lateral connecting piece 5.

When the reinforcement of the cargo 3 is released:

S2.1, the locking piece 6 is released to fix the two telescopic jacking pieces 2 with medium height in the two adjacent jacking assemblies, and the lateral connecting piece 5 is released to connect the lateral fixing structures of the vertical supporting beams 1 on the same side in the two adjacent jacking assemblies.

The following steps are performed for each jacking assembly:

S2.2, switching the telescopic jacking members 2 from the jacked state to the released state, in particular rotating the sleeve 21 such that the two lead screws 22 retract to the released state enabling the vertical support beams 1 to exert no pressure on the cargo 3.

S2.3, connecting the telescopic end of the telescopic supporting piece 2 with the vertical supporting beam 1, and removing the telescopic supporting piece 2 and the vertical supporting beam 1. If the structure of fig. 4 is adopted, the telescopic supporting piece 2 needs to be continuously shortened after being in a release state so as to be separated from the vertical supporting beam 1; if the structure shown in fig. 5 is adopted, the connection of the first mounting structure and the second mounting structure by the mounting structure connecting member 4 needs to be released.

In the reinforcement method of the present embodiment, the vertical support beam 1 is used to apply force to the cargo, and the vertical support beam is used in combination with the container floor as a support to stably fix the cargo 3 in the container so as to prevent the cargo from tilting, focusing on a wide range of force application in the height direction of the cargo. The vertical support beam 1 is a force application member for the cargo 3, and the telescopic jack 2 is telescopic, so that the vertical support beam can be applied to the cargo 3 with various heights and various thicknesses and can be repeatedly used. In the case of different lengths of the cargo 3, a plurality of groups of jack-up assemblies may be selectively provided, and thus, the lateral jack-up device of the present embodiment is also applicable to cargo 3 of various lengths and can be repeatedly used. In summary, the cargo reinforcement method is used for the container, the cargo 3 is reinforced and stabilized, the transportation is safe, and the transportation cost is reduced. In addition, when the lateral jacking device is installed, workers can operate the lateral jacking device by standing on the floor of the container without auxiliary tools such as a stool, and the lateral jacking device is safer and more convenient to operate.
