Description

Technical Field

[0001] The utility model belongs to the technical field of coil steel box transportation, and particularly relates to a rubber cushion plate for coil steel transportation. Background Art

[0002] When loading coil steel, it cannot be placed in the middle and dropped. During the dropping process of the coil steel, comprehensive forces such as impact force, shear force, frictional force, and sliding force will be formed on the rubber plate in the box groove. It is necessary to bear the force generated when the coil steel drops unilaterally. Therefore, the force borne by a single piece during loading is very large. Over time, the rubber plate will be damaged. In most cases, the rubber plate is bonded in the box groove with glue. The technological process during bonding is complex. It is necessary to first clean the rubber plate, repeatedly apply glue, let it stand, and then knock to discharge air, and apply edge-sealing glue, which consumes a lot of time. When the rubber plate falls off and needs to be replaced, the installation process is repeated, which is time-consuming and laborious.

[0003] In the prior art, when transporting coil steel, it is usually shielded with straw mats or a straight baffle structure. However, the consumption of straw mat shielding is huge, the bundling and reinforcement operations are not standardized, the time is long, and the transportation efficiency is not high; adopting a straight baffle structure requires welding connection with the transportation equipment, there are too many movable parts, the baffle structure is unstable, and it is a split structure, making it difficult to achieve accurate installation.

The rubber cushion plate includes a steel plate, a rubber plate is laid above the steel plate, the rubber plate is bonded to the steel plate by a vulcanization process, several installation holes are opened on the steel plate outside the rubber plate, and a bottom baffle is provided on the surface of the leg below the rubber cushion plate.

A plurality of mounting holes 3 are opened on the steel plate 1 on the outside of the rubber plate 2, and the number of mounting holes is set according to the length of the steel plate and the requirements. After calculation and analysis, 8, 6 and 4 holes are set from long to short respectively. The steel plate 1 is fixed to a pallet or a support frame for placing a coil steel box by passing bolts and nuts through the mounting holes.

[0024] Preferably, the bolt has an M12 diameter and a red two-component fluorine-resistant adhesive is applied to the thread of the bolt, which remains inert on the thread until the bolt and nut are assembled and screwed together to release a fast-agglomerated resin, which fills all gaps in the thread. After curing, the threaded assembly is sealed and locked, and can also prevent the threaded assembly from loosening during vibration.

[0025] Priority: In order to increase the safety of the rubber pad, design measures to prevent the rubber pad from falling off.
