Description

Technical Field

[0001] The utility model belongs to the technical field of container corner pads and relates to a composite rubber used for flexible corner pads of containers. Background Art

[0002] At present, when stacking containers in container yards, when containers land, they are directly placed on the interlocking blocks of the yard, which will cause varying degrees of damage to the containers and the interlocking blocks. In order to reduce this damage, when the container lands, the landing speed needs to be reduced as much as possible, which greatly reduces the loading and unloading speed of the container. In addition, the maintenance of the interlocking blocks in the yard is time-consuming and labor-intensive. Some yards have set up ordinary rubber pads as container corner pads, but because ordinary rubber has low hardness, large deformation, poor tear resistance, and is easy to damage, it cannot meet the needs of container corner pads well, and it has to be replaced frequently if it is barely used. In order to increase the loading and unloading speed of containers and reduce the damage to containers and corner pads during loading and unloading, a container flexible corner pad made of composite rubber material has been designed to replace the interlocking blocks and ordinary rubber pads in container yards. Utility Model Content

[0003] The utility model material is designed for container yards in order to improve the loading and unloading efficiency of containers and reduce damage to container stacking foundations and containers themselves.

[0004] The technical solution of this utility model:

[0005] A composite rubber for container flexible pad corners comprises a rubber-impregnated canvas braided layer, a weft-knitted strong steel wire braided layer and a warp-knitted strong steel wire braided layer. The above layers are vulcanized with styrene-butadiene rubber to form a composite rubber with a thickness of 25 mm.

[0006] From bottom to top, the composite rubber includes a lower rubber-impregnated canvas braided layer, a weft-knitted strong steel wire braided layer, a warp-knitted strong steel wire braided layer and an upper rubber-impregnated canvas braided layer, which can greatly increase the compression and tensile strength of the composite rubber as a whole.

[0007] The upper surface of the composite rubber is provided with rubber protrusion particles, which are a rubber protrusion wear-resistant layer and play a role in increasing friction.

[0008] The thickness of the strong steel wire braided layer is 2.5mm and the crushing strength is not less than 720KN / m.

[0009] The thickness of the rubberized canvas braid is 1mm ， Crushing strength is not less than 20KN / m.

[0010] The hardness of styrene-butadiene rubber is 75°A, and the tensile strength is 12.5N / mm. The overall composite rubber material cushion layer has good integrity and strong tear resistance.

[0011] Beneficial effects of the utility model:

[0012] (1) Excellent technical performance indicators:

[0013] The composite rubber material can adapt to the environmental temperature of -30℃~+80℃, has strong applicability and good durability; has good integrity, strong tear resistance, and is not easy to be damaged; has high hardness and is not easy to deform; at the same time, it has good impact resistance and shock absorption performance, and can be used as an excellent protective material for container corner pads; saving later maintenance and repair costs.

[0014] (2) Reduce the time of crane box drop operation and greatly improve production efficiency:

[0015] Due to the shock-absorbing properties of rubber, the landing speed can be accelerated and the operation time can be reduced, thereby increasing the loading and unloading speed of containers and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the technical solution of the present invention clearer and more explicit, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The utility model is a safety protection material suitable for container yards, which can prevent and reduce ground damage caused by impact between containers and the ground when containers are hoisted and landed through yard bridges.

[0021] like Figure 2 As shown, the composite rubber flexible corner is composed from top to bottom: a rubber raised wear-resistant layer 6, an upper rubber-impregnated canvas woven layer 5, a warp-knitted strong steel wire woven layer 4, a weft-knitted strong steel wire woven layer 3, and a lower rubber-impregnated canvas woven layer 2, which is formed by vulcanization and compounding of styrene-butadiene rubber 1.

[0022] The shock-absorbing property of styrene-butadiene rubber 1 eliminates the instantaneous impact on the load-bearing device and the ground foundation when the container falls. At the same time, styrene-butadiene rubber 1 has a large hardness and can control the compressive deformation of the composite rubber.

[0023] The strong steel wire braided layer is woven with high-strength steel wire and has super high tear resistance;

[0024] The combination of the impregnated canvas woven layer and the styrene-butadiene rubber 1 can provide good bonding and integrity, increase the tear strength, and at the same time have vertical flexibility without affecting the impact resistance of the rubber.

[0025] After the styrene-butadiene rubber 1 is compounded with two layers of strong steel wire braid and two layers of rubber-impregnated canvas braid, it has a high tear resistance, which reduces the damage of the composite rubber material during use and reduces the cost of later maintenance and repair, while not affecting the impact resistance of the rubber. The composite rubber material is currently the most tear-resistant and durable ground foundation anti-impact protection system in my country, which can effectively reduce the damage to containers.

[0026] When in use, it is fixed by installing the buckle 7.

[0027] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
