Detailed ways

The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

Referring to FIG1 , the utility model provides a cargo transportation reinforcement structure, which is used to solve the problems of long reinforcement time, stress concentration, and factors such as the storage environment, material, and moisture content of the wood strips that affect the reinforcement quality in the traditional wood strip reinforcement method. The cargo transportation reinforcement structure of the utility model is particularly aimed at the transportation and fixation of rolled steel. The rolled steel is wound in a cylindrical shape and hollow inside. The weight of the rolled steel is relatively large, and the weight of a single rolled steel can usually reach between 4 tons and 9 tons. The reinforcement structure of the utility model adopts an inflatable inflatable bag to clamp the cargo. The inflatable bag is arranged around the cargo. The inflatable bag is used to clamp and fix the cargo around, which can prevent the cargo from moving during transportation. The inflatable bag has high operating efficiency, and the pressure of the inflatable bag is more dispersed, which can ensure uniform force and avoid stress concentration. The inflatable bag has the advantage of standardization, which can reduce the influence of factors such as environment, material, and moisture content. The cargo transportation reinforcement structure of the utility model is described below in conjunction with the accompanying drawings.

Referring to Fig. 1, it shows a three-dimensional structural diagram of the cargo transportation reinforcement structure of the utility model clamping cargo in a transportation box.

As shown in Figure 1, the cargo transportation reinforcement structure of the utility model is used to reinforce the cargo 12 in the transport box 11. The reinforcement structure includes inflatable bags 21 arranged around the cargo 12. The inflatable bags 21 are inflated to fill the gaps around the cargo to clamp the corresponding cargo 12. The inflatable bags 21 that can clamp the cargo 12 are arranged around the cargo 12 to improve the stability of the cargo 12 in the transport box 11 and prevent the cargo 12 from moving. The inflatable bags 21 are inflated and expanded to press against the cargo 12 to apply a clamping force to the cargo. When the transport box 11 is subjected to vibration or other external forces, the inflatable bags 21 can have a certain buffering effect, thereby effectively protecting the cargo 12.

Specifically, the air bags 21 are arranged around the cargo 12 including the front side, the rear side, the left side and the right side of the cargo 12 , that is, the cargo 12 is clamped from four directions.

In a specific embodiment of the present invention, the size of the air bag 21 is adapted to the size of the corresponding side of the cargo 12. The size of the air bag 21 after expansion can cover the corresponding side of the cargo 12, so that the corresponding side of the cargo 12 can be completely fitted with the corresponding surface of the air bag 21, so that the air bag 21 provides good support and protection for the cargo 12.

In a specific implementation of the present invention, the air bag 21 is disposed between the cargo 12 and the corresponding side walls of the transport box 11 .

After the goods 12 are loaded into the transport box 11, an inflatable bag 21 is arranged between the goods 12 and the corresponding side walls of the transport box 11. At this time, the inflatable bag 21 is in an empty state, and then air is inflated into the inflatable bag 21. The inflated inflatable bag 21 can be well supported between the goods 12 and the corresponding side walls of the transport box 11.

Furthermore, the inflatable bag 21 is also arranged between two adjacent goods 12. When two or more goods 12 are arranged in the transport box 11, the inflatable bag 21 is also sandwiched between the two goods 12 to support the two goods 12.

When the airbag is inflated, the reinforcement result is controlled by controlling the inflation pressure, achieving a standardized control and fixing result. When the airbag at the door of the transport box is inflated, it should be noted that the inflation volume should not be too much to avoid affecting the airtightness of the door.

In a specific embodiment of the present invention, as shown in FIG1 , the inflatable bag 21 includes two airbag bags arranged opposite to each other and a connecting belt connecting the top and bottom of the two airbag bags, and a closed inflatable space is formed inside the airbag bag. The airbag bag is provided with an inflating nozzle and an inflating valve, which can be connected to an inflating device to inflate the airbag bag.

The inflatable bag 21 has two airbags and a double-layer structure. It can have a certain thickness, and the thickness can be designed according to the size of the gap between the goods and the transport box, so that the inflatable bag 21 can meet the reinforcement of goods of different models and different assembly methods.

In a specific embodiment of the utility model, the inflatable bag includes an inner membrane bag with an inflatable space formed therein and an outer bag that is covered on the outer side of the inner membrane bag and connected to the inner membrane bag. The outer bag is preferably a woven belt. The inner membrane bag and the outer bag are provided with an inflating nozzle and an inflating valve for connecting an inflating device to inflate the inner membrane bag. The inflatable bag is a single-layer structure.

In a specific implementation of the present invention, as shown in FIG. 2 , a stopper 22 is provided at the bottom of the transport box 11 corresponding to the goods 12 , and the stopper 22 is provided at the side corresponding to the goods 12 .

The upper surface of the bottom plate 111 of the transport box 11 is provided with a stopper 22, which is preferably provided on the left and right sides of the goods 12 to limit the left and right movement of the goods 12. Furthermore, the stopper 22 is also provided on the front and rear sides of the goods to limit the front and rear movement of the goods 12. The stopper 22 provided can improve the structural stability of the goods 12 in the transport box 11.

Preferably, the bottom plate 111 is provided with a plurality of rail grooves, in which rails are embedded, and when the stopper 22 is required, the rail is taken out and fixed on the bottom plate 111, and then the stopper 22 is slidably fixed on the rail. Goods can be placed in the rail grooves, and the rail grooves can provide a certain support for the goods. Preferably, rubber pads are attached to the rail grooves to provide friction resistance for the goods.

Furthermore, the cargo 12 is cylindrical, and the surface of the stopper 22 opposite to the cargo 12 is a curved surface.

In a specific embodiment of the present utility model, the cargo is preferably a hollow cylindrical structure. When reinforcing the cargo, it also includes: a plurality of connecting hooks are arranged on the edge of the bottom plate of the transport box. After the cargo is placed on the bottom plate, a connecting rope is passed through the hollow part in the middle of the cargo, and the ends of the connecting rope are hooked on the corresponding connecting hooks. The connecting ropes are arranged on the left and right sides of the cargo. In this way, the cargo can be fixed by the connecting ropes. When the cargo shakes or moves left and right, the connecting ropes can transmit the force generated by the shaking or movement of the cargo to the connecting hooks and the bottom plate of the transport box. The bottom plate can be used to share the force of the inflatable bag and the side walls of the transport box, thereby improving the safety of the reinforced structure.

In a specific implementation of the present utility model, the supporting force provided by the air bag 21 is greater than or equal to 1.5 times the weight of the cargo.

The following is an analysis of the forces acting on the cargo when it is tilted. If the cargo is tilted at an angle of 30° without any reinforcement, the forces acting on the cargo are gravity G and the bottom plate support force F2. If the cargo needs to be kept from moving, sufficient support force must be provided. Assume that the support force provided is F1. The gravity G of the cargo is decomposed into G1 and G2, where G1 = G*sin30°. If the cargo needs to be kept under a balanced force, G2 = F2 and G1 = F1. If the support force provided by the air bag 21 meets the force value of G1, the minimum reinforcement requirement can be met. The weight of the cargo is

3000～12000KGS, the inflatable bag theoretically needs to provide a support force of at least 1500～6000KGS, and the inflatable bag 21 of the utility model provides a support force of 1.5 times the weight of the goods, and the support force provided is converted to 4500～18000KGS, which is much greater than the theoretical minimum support force value. Therefore, the reinforcement scheme of the inflatable bag 21 can meet the support requirements of the goods and protect the transportation safety of the goods. In addition, the goods are supported by rail grooves and blocks in the transport box, so that when the transport box tilts 30°, the actual tilt angle of the goods will be less than 30°, thereby improving the safety factor of the reinforcement.

The side walls of the transport box can withstand 0.6 times the weight of the maximum load. When the container is tilted 30°, the weight exerted by the cargo on the inflatable bags is 0.5 times the weight of the cargo itself, and the weight transmitted to the side walls of the transport box by the inflatable bags is also 0.5 times the weight of the cargo. In this case, the side walls of the transport box will not be damaged by swelling or other damage.

In a specific embodiment of the present utility model, as shown in FIG3 , the number of goods 12 in the transport box 11 is at least three, and at least three goods 12 are placed at intervals in the transport box 11;

There are four inflatable bags 21 spaced apart along the length direction of the transport box 11, and the length of the inflatable bags 21 spaced apart along the length direction of the transport box 11 is consistent with the sum of the side widths of two cargoes arranged side by side; there are also eight inflatable bags 21 spaced apart along the width direction of the transport box 11, and the inflatable bags 21 spaced apart along the width direction of the transport box 11 are located between two adjacent cargoes 12 and between the cargoes 12 and the corresponding side walls of the transport box 11, and the length of the inflatable bags 21 is consistent with the side length of the corresponding cargo 12.

The transport box 11 of the present invention is a container that can be used for transportation by airplane, land transportation tool and sea transportation tool.

The traditional packaging and fixing method for rolled steel is to use wooden strips to support and use fixing belts to tie and fix, and also to use wooden strips to make a support frame to clamp and support the rolled steel in the container. This traditional packaging and fixing method has the following problems during transportation: the loading time of this packaging and fixing method is relatively long, usually about 40 to 90 minutes, and the number of wooden strips used in a container is also relatively large, which is a waste of materials. In addition, the wooden strips can only be used once, which is costly. The wooden strip support is very easy to be damaged due to stress concentration during transportation. After the support formed by the wooden strips is damaged, the rolling of the rolled steel in the container can easily break the side wall of the container, thereby causing the rolled steel to roll out of the container, making it difficult for this traditional packaging and fixing method to effectively protect the rolled steel.

The cargo transportation reinforcement structure of the utility model adopts inflatable bags to inflate and clamp cargo, which has the advantage of high operating efficiency. The loading time can be completed in about 15 minutes, which can greatly save the loading time compared with the traditional wooden strip support method. Correspondingly, the unloading time is also short, which can improve the efficiency of unloading.

The inflatable bag can perfectly fill the gap between the rolled steel and the side wall of the container, providing good support for the rolled steel. On the one hand, it can effectively utilize the space in the container, and on the other hand, it can protect the rolled steel and prevent it from rolling. The large force-bearing area of the inflatable bag makes the pressure distribution more uniform, and it also has a certain shockproof effect. During reinforcement, you only need to control the inflation pressure of the inflatable bag to effectively control the reinforcement result, which can ensure that the structure of the rolled steel and the container is intact and there will be no fixation failure.

The utility model is described in detail above in conjunction with the embodiments of the drawings. A person skilled in the art can make various variations of the utility model according to the above description. Therefore, some details in the embodiments should not constitute a limitation of the utility model, and the scope of protection of the utility model shall be defined by the scope of the attached claims.
