Description

Cargo restraint system

Background of the present invention

The present invention relates to a kind of reliable and effective system that retrains goods in transit of improvement.Particularly, the present invention relates to a kind of fixing and the non-new system that moves of requiring that constrains in case, bucket and the analogue in the intermodal container in the cargo hold, on this system's placement flat bed truck trailer, on the truck or in truck trailer, within railcar and the similar carrier.

In the U.S. and overseas, most outlet transportation product all are to deposit in the 20 or 40 feet long rectangle intermodal container.These freight containers are made by steel, corrugated sidewall, structurally can the oneself support with crash-resistant.When transporting by ocean, railway or highway, several intermodal containers can one be deposited on another.In freight container, bucket is equipped with actual goods with case.All these power all might apply a sizable power to intermodal container.

When through railway transportation, the dull and stereotyped railcar of transportation intermodal container can constitute by a what is called " rolling " method (humping).In the method, dull and stereotyped railcar is pushed into the raised portion of track, then, making it to roll enters the marshalling yard that constitutes train crew district.When a joint car rolls when entering the fixing car team of delegation, collision makes adaptor union be locked together mutually.Yet vibrations that are several times as much as gravity of goods are also bestowed in this collision.And in the process of transportation, the compartment is faced with the inclination of unexpected brake weight, the collision that goes out to enter the station, railway vibration, track, and waves.When intermodal container via when sea-freight, goods wherein is faced with the storm power of fluctuating, comprising: driftage, pitching, rise and fall, wave and fluctuate.On express highway, intermodal container and goods are wherein experiencing acceleration/accel and centrifugal load, brake suddenly and vibration.

With regard to motion, in transportation, intermodal container is two entities that separate with wherein goods.Freight container can be placed in the cargo hold of boats and ships, in the dull and stereotyped railcar, in the flat bed truck trailer or within the analogue.And goods only is fixed on the freight container, otherwise is can be free-moving in intermodal container.

When freight container change of direction or speed, goods often continues to move along original path, runs into the inwall of freight container up to it.If do not have certain constraint and/or shock mitigation system, goods will accumulate sizable momentum that has nothing to do with freight container.The size of momentum equals the product of quality and its speed of object.Under the situation of big cargo load,, also can produce sizable momentum even atomic little change takes place for direction or speed.When goods touches inwall or when door of freight container, this momentum is kept to zero necessary power is absorbed by goods.This power may cause damage, inner wall of container or the damage of door of goods, the damage of goods packing, and, when goods is objectionable impurities, may cause dangerous leakage.Therefore, goods being obtained with the irrelevant momentum of freight container is inhumanly to be willing to.The method that realizes this purpose is: by the constraint goods in freight container, thereby make goods and freight container in the process of transporting, be connected as a single entity basically, and on function, operate as an object.

In the past, shipload is fixed in the freight container, to eliminate motion or the displacement of wanting in transportation.With several different modes tank or other container are retrained.At first, goods is stablized goods by the method for a kind of load-lock and timber reinforcing.This system relates to the timber that is positioned over key position between freight container back door and the load surface.Yet, this be a kind of expensive time-consuming, generally speaking also be the means of the not high restraint of loads of efficient.Fixation procedure needs the carpenter, and that this is a contractor is beyond power.And the timber baffle plate is installed consuming time, and also not cost saving.Again furtherly, the timber fixture is more crisp, can face the possibility of inefficacy under impacting suddenly.And the fixing method of traditional load-lock and timber is inefficient in some task.For example, fill effective means double-deck bucket of stacking 80 50 five gallon bottles in 20 feet long freight containers of an intermodal container.Yet,, between load surface and back door, only be left about one to two inch space if do like this.The not nearly enough space of fixing 80 used timber of bucket, one to two inch space.Therefore, when the timber fixture was used as a kind of constrained system, the shipper had to transport the sufficient freight container of those capacity, thereby has reduced conveying efficiency, and has improved traffic cost.

Similarly, the explosive Public Roads Administration has been established a kind of check criteria, with judge a certain particular constraints system whether safe enough fixing dangerous freight.In some cases, this innings disagreed with the fixing method of traditional load-lock and timber and come the peril of transportation goods.

Other known constraint means have been used rope, belt or support.The method that past occurs illustrates the performance of weakening before toward performance, even and usually be not suitable for about beam loading under moderate condition on function.Therefore, need seek a kind of in intermodal container cargo anchoring system, that function is effective, expense is cheap, the labour saves, and will meet the regulation of shipping office and explosive Public Roads Administration.

The patent No. method and apparatus of at least a constraint cargo movement that has been 4,264,251 U.S. Patent Publication has overcome above-mentioned defective at the common task of this subject application.The disclosed invention of this patent comprises the sealing band, an immobilization material safety strap and the mechanical device that adjoins that are fixed on the corresponding sidewall of freight container, and is used for the two ends of sealing band are connected together, and forms safety and the constraint of tension.This invents disclosed content here as a reference as elaborating.Therefore, the notion as the material safety band of obstacle constraint goods or shipload is disclosed in ' 251 patents.

In ' 251 patents, material safety band application mode is similar with the extension wallpaper, wherein, imposes independently alite paste on the surface that desire is pasted.Use this constraint safety strap then.Except needs independently the alite paste, the system in past also exists in the junction and connects weak problem.Meet at together junction at safety strap, the chance that exists joint face to slide.And intermodal container has corrugated wall.Because independent alite paste may be used by neither one uniformly, a constraint safety strap is applied to an independently cooresponding difficulty of alite paste so these ripples make.

In the past, constrained system needs a plurality of devices, and the storage difficulty is installed effort, and needs skilled labor to a certain degree.The employed safety strap of system, nail, fixer or bolt are even also need a large amount of storage spaces when not using.And such system has increased the workman's of constraint goods security risk.

Further again, employed product of past and method depend on the annex in the cargo-type container, and usually can not fix a part of load.That is,, may there be essential fixer in the place of using fixer so if load can not be stretched over enough distant places at freight container rear portion.

Foregoing problem has no intention detailed illustrating, but only lists the problem that some may reduce cargo restraint system efficient.Perhaps also exist other and be unworthy the problem discussed, still, the problems referred to above suffice to show that cargo restraint system of the prior art is very not satisfactory.

The detailed description of embodiment

The context of invention

Will there is shown an operational outfit environment of the present invention with reference to Fig. 1 especially now, wherein, intermodal container 10 is just being loaded onto boats and ships 14.The present invention can be used for fixing goods and the delivery container in the intermodal container 10.Particularly, Fig. 1 has described a series of intermodal containers 10 that are positioned at harbour 16, and just carries out handling with hoisting crane and will be placed on cargo hold or the ship deck.

Fig. 2 illustrates the axonometric drawing of the present invention at another kind of working environment.20 feet long intermodal containers 18 are placed on the flat bed truck trailer.Then, truck trailer is placed in again on the railway platform truck 20 and transports by a land route.The city is used for long-distance transportation to intercity railway line, and the truck haul of point-to-point then is used for goods is delivered to the locality.

Fig. 2 has also described the cutaway drawing of a Cargo restraint safety strap 24, and this safety strap has constituted one embodiment of the present of invention, adheres to the inner wall surface 26 of cargo-type container 18 during work.An inner wall surface 26 that retrains safety strap 24 attached to cargo-type container 18 is extended along the back of load 22 then.The safety strap 24 on opposite is in a similar fashion on the opposite inwall attached to freight container, and extends along the back of load 22, connects together with first safety strap then.

Cargo restraint safety strap 24 can be in the position 28 usefulness adhesive tape stickings in load 22, to avoid causing the safety strap sagging by compression owing to the load that the head and the tail collision causes.Fig. 2 has described the present invention who is in complete mode of operation, is suitable for making things convenient for transportation and can cause that displacement damages to goods 22.

The constraint safety strap

Fig. 3 again, Fig. 3 discloses and has retrained safety strap 24 according to the preferred embodiment of the invention.Particularly, describe a formation volume 26 of the present invention and repeated polyester safety strap 24.Preferably, an end of polyester safety strap 24 is approximately ten inches wide, and the width of the other end is system's inch (system inches).Yet,, can replace with other width according to the needs that increase or reduce intensity.Preferably a kind of spunbonded olefin of polyester safety strap 24 (spun bonded olefin), but also can be by acrylic acid, promptly a kind of resin difference poly-mer (resin differential polymer) or VALERON  form.This class material as DuPont, Hoeschst Celanese and the manufacturing of other makers.Safety strap 24 can be a monolithic, or embeds with polyester or polyethylene fibre line feeder, and its mode is discussed below.

In a kind of specific embodiment of the best, as shown in Figure 3, cylinder 26 is made up of the cargo load constraint safety strap 24 of a series of repetition.Each load restraint safety strap has a head end 32, and its shape is generally rectangle, and width is about 10 inches, and length is about five feet.One end of rectangular section 32 axially is connected in a conical section 34 that is generally frustoconical.The top 36 of frustro-conical segment holds together with an end of rectangular section 32.In a kind of preferred embodiment, the top of frustoconical is 10 inches, and bottom 38 is 16 inches.The length of frustoconical is about 7 feet, thereby makes the total length of each constraint safety strap 24 be about 12 feet.

Fig. 2 again, alite paste coat are coated on first of rectangular end 32 as constraint safety strap 24 at least one with coextending, and can be reliably will constraint safety strap 24 be pasted on an inner wall surface 26 of freight container 18.The best acrylic acid of alite paste is formed, but also can be resin or poly-mer.Alite paste is a kind of polyacrylic acid alite paste, it is characterized in that viscosity by force, easily peel off, the shearing strength value height.Combine very closely between alite paste 30 and glass, metal, paper and the film.And it has good anti-low-temperature characteristics, and adding has the UV stable device.

As shown in Figure 3, barrier paper 40 is applied on the alite paste coat of 32 first of safety strap sections, and, be installed with row's perforation on top 36 along frustoconical 34.Also can use the independently not perforated barrier paper panel of another kind, end-to-end being close together perhaps at one end has some overlapping slightly.Perhaps, also can use to periodic intervals the fragment of barrier paper and alite paste.

Fig. 4 discloses another kind of specific embodiment of the present invention, comprises and Cargo restraint safety strap 24 similar cargo security bands 42.In this specific embodiment, safety strap 42 has first section 44 of being generally rectangle, and is similar with the section 32 shown in Fig. 3 in all respects.Cargo restraint safety strap 42 is different from safety strap 24 and just is, general frustro-conical segment 46 has an arc and outer recessed lateral edges 48, as shown in Figure 4.In the preferred form of this embodiment, section 44 is 10 inches wide, is five feet long.General frustoconical with bowed sidewalls, its top dimension are 10 inches, and bottom size is 16 inches.

Fig. 5 has described another specific embodiment of the present invention, and wherein, a Cargo restraint safety strap 50 is made up of three sections.First end section is generally the rectangular elements 52 that covers alite paste and barrier paper, and combining between safety strap 50 and the delivery container sidewall can be provided reliably.As mentioned above, this section is 10 inches wide, is five feet long.The second end section generally also is a rectangle, and width is 16 inches, and length is about 2 feet.Rectangular section 54 also covers one deck alite paste and barrier paper.Interlude, promptly the frustro-conical segment 56 of Chan Raoing is extended between first end section 52 and the second end section 54.The width at the top 38 of frustoconical is 10 inches, and combines together with an end of section 52, and the width of bottom 60 is 16 inches, and combines together with an end of the second end rectangular section 54.One deck alite paste and barrier paper are applied to the first above-mentioned rectangular section 52 and second rectangular section 54 at least.If the alite paste material is applied under any part or all the situation of frustro-conical segment, barrier paper also will be applied to this part so.

Fig. 6 shows the constraint safety strap 62 among another embodiment of the present invention.This safety strap is identical with safety strap described in Fig. 5 substantially.Safety strap 62 is made up of three sections 64,66 and 68, and is corresponding with section 52,54 and 56.The difference of constraint safety strap 62 is that the general frustoconical looping along 68 is recessed shape outside the edge 70 and 72 of part has.This makes the elasticity of safety strap to adjust, to adapt to different specific needs.

Although the Cargo restraint safety strap described in Fig. 3-6 24,42,50 and 62 preferably is made up of spunbonded olefin, in some cases, need to strengthen its intensity and durability.

As shown in Figure 7, can cooperate with the splicing thread 74 of a sinusoidal interleaving mode one longitudinally parallel model line 76 add the strong constraint safety strap vertically and transverse strength.Perhaps, also can use tightening security of a vertical interleaving mode to be with 78 separately, or match, thereby the stability of enhancing is provided with line 76.

The polyester fortifying fibre of forming safety strap can be made into different patterns.The arrangement of fiber can be longitudinally, horizontal, the diagonal angle, sinusoidal or above several modes comprehensive.And, these reinforcings fiber can be sub-thread or multiply, or mix.

In above-mentioned all embodiment, the placement of the selectivity of alite paste makes a volume 26 of safety strap 24,42,56 or 62 can satisfy specific user's requirement and customizes.The result is, alite paste and barrier paper will only be placed on essential place of using, and can not appear on the position that the user do not wish the safety strap that the alite paste parts occur.The selectivity of alite paste is used and is made user's cost reduce, and the economy of total system then is improved.For example, the length that is designed for the intermodal container of this product is 20 or 40 feet, and width is 92 inches (7 feet, 8 inches), highly is 92 inches.If the user only uses the intermodal container of this size, alite paste will only use any middle lap in sidewall sections 32 and frustoconical bottom so, or rectangular section 54 and 66.Therefore, if the constraint safety strap is made like this, will be five feet so has alite paste, and five feet do not have alite paste, and two feet alite paste is arranged is repetition, thereby make the cost of alite paste reduce greatly, if without alite paste, then its cost is zero.

Use the method for polyester constraint safety strap constraint goods

Please note Fig. 9-11 now, wherein disclose according to a preferred embodiment of the present invention and used constraint safety strap 24 to fix the concrete grammar of load.

Fig. 9 discloses the first step in four steps.Beginning, user 80 cuts out two required polyester constraint safety strap of each load baffle plate from cylinder 26.Safety strap 24 length are cut to 12 feet, and cut out length from another cylinder and be 4 to 5 feet one the 3rd and paste band.Glue line should be from 2 feet behind the door of freight container, and extend 5 feet at least from the front end (nose) of load object container, to guarantee having only tractive force to act on the alite paste part of safety strap when the anything unexpected masterpiece is used for goods.

User 80 divests barrier paper 40 to expose the alite paste safety strap 32 of certain-length from polyester constraint safety strap 24.Then the one side with alite paste of safety strap 24 is applied to the almost parallel corrugated inner wall of container surface 26 of container base on.Although not every inner wall of container all is undulatory, if the inwall of certain freight container is undulatory, so the user to operate along undulatory profile be very important.This application process can be so that alite paste can be attached to the inwall of freight container tightly.

Because alite paste to presser sensor, can make safety strap tightly be affixed on the inwall 26 of freight container 18 in conjunction with cylinder 82 with one.Placement safety strap 24 is repetition with the process of alite paste on the relative inwall of freight container.Then, two safety strap 24 are away from the rear portion of freight container 18, and freight container is then loaded onto goods.Next, safety strap 24 be wound in load around, and long enough makes that it can be overlapping.Polyester constraint safety strap 24 is wound in around the end of load, and barrier paper 40 is then towards the direction away from goods or load.

Figure 10 has described a step in the use of the present invention, and wherein the lap of safety strap 24 is tensioned, and throws off barrier paper then to expose the alite paste of joint.Here, user 80 inserts lap with a tension force instrument (clothes-pin (clothespin)) 24.Then, user 80 places an end of clothes-pin with a small wrench 86, and a long handle spanner 88 is placed top (handle is concordant with load).Then, user's 80 usefulness spanners 86 and 88 safety strap 24 tensions with lap.

The patent No. is 4,264,251 US Patent has described the using method of tension force instrument in detail very much, we have been combined into it our list of references before this, therefore, here repeat its content no longer in a large number, just propose a lime light, promptly should the concise and to the point method of describing form a vertical joint 90 at the end of two safety strap 24.

In case strain after the safety strap 24 of two reservations, tear barrier paper off and can expose four to five feet long alite paste bands that are positioned at the safety strap bottom.In Figure 11, the user removes barrier paper from the 3rd safety strap material 92, preferably four to five feet long, places then by two the formed joint of overlapping safety strap 90 places.As mentioned above, in this position, the alite paste of safety strap 24 ends is exposed.Add the 3rd constraint material 92, to guarantee alite paste combining closely between three safety strap to alite paste.The alite paste that is become in this step has increased safety of the present invention and reliability to the combination of alite paste just.

Figure 11 has also described the optional final step in this process.In this optional step, use adhesive tape 94 to make by combining closely between formed safety strap 24 baffle plates of polyester safety strap and goods or the load, to avoid because the compressive force that head and the tail collide makes the safety strap sagging.

After having described the preferred embodiments of the present invention in detail, it is very useful illustrating major advantage of the present invention more briefly.
