The utility model content

The purpose of this utility model is at above-mentioned deficiency, provides a kind of no under casing shape simple in structure, that cost is low, result of use is good to go up envelope railway netting.

The technical scheme that realizes the utility model purpose is:

This no under casing shape is gone up envelope railway netting, by on enclose muscle, enclose muscle in down, tether is formed, characteristics be with on enclose muscle and down in enclose the net muscle that muscle is connected and be the rectangular box-shaped that is complementary with the boxcar, have in down in the bottom surface of rectangular box-shaped net muscle and to enclose the mesh that muscle surrounds, in down, enclose and be connected with at least 1 protruding nematophore on the muscle, be fixedly connected with at least 1 protruding thorn on the protruding nematophore.

The shape of described mesh can be difformities such as oblong, ellipse or prismatic.

The body of described protruding nematophore can be not homomorphs such as spheroid, cylinder, cuboid or square, has connecting bore on protruding nematophore, utilize connecting bore realize protruding nematophore with down in enclose muscle flexible connection.

The utility model is simple in structure, can select the existing raw MAT'L of making railway netting for use, and protruding nematophore can be selected plastic or other material for use, and adopts conventional processes to make, and implements easily.

This no under casing shape is gone up envelope railway netting and is compared with traditional " upper sealing type netting ", and the netting that levels off face is box-formed shape, and promptly the cuboid that is complementary with the boxcar has removed central network simultaneously, with the protruding nematophore replacement central network tension of net muscle in length and breadth; Reduce the area of purse seine, removed the redundance that bundlees four jiaos of reinforcing backs.

Using method and traditional " upper sealing type netting " are basic identical, earlier this no under casing shape is gone up envelope railway netting be placed on pre-buried goods above, pave the tension back and continue the number of plies of lade to regulation, upwards dig netting again, the tension tether is bundled into one with the backing goods by the tether on the netting.Continue cargo-carring goods be pressed in mesh edge, box-shaped net muscle bottom surface with down in enclose on the protruding nematophore that muscle flexibly connects, thereby net muscle bottom surface can be compressed because the effect of protruding nematophore epirelief thorn makes netting be unlikely to play in the Freight Transport way; Because therefore net muscle not in the mesh of net muscle bottom surface, can not influence alongshoreman's field operation.In addition,, can not become the string bag, both guarantee cargo transportation security, save the raw MAT'L of netting again at the quadrangle of netting because netting is box-shaped.

The utility model can be designed to different size according to the difference of using vehicle, is applicable to the transportation of open-top car shipment packed freight or bag cargo, particularly member grain etc., and field of application is very extensive.Have simple in structurely, reasonable in design, easy to use, implement easily, cost is low, and characteristics such as dependable performance both had been convenient to loading and unloading operation, can better guarantee safety of railway traffic again, had promotional value.
