Description

Technical Field

[0001] This utility model belongs to the field of railway open wagon packaging technology, and in particular relates to a buffer pallet for preventing damage during forklift loading. Background Technology

[0002] Currently, both hot and cold rolled steel coils are mostly transported by train. A steel coil support frame is a support structure used to hold and secure the steel coil during transport. These frames are typically robust welded structures, usually consisting of a base and side supports. The side supports are symmetrically welded to the base, and the inner cavity of the support frame for holding the steel coil has a trapezoidal cross-section. The base is welded from channel steel, with a base plate and a support panel anchored to the two short sides of the base, respectively. The side supports are welded to the support panels, and a slanted panel is welded to the surface of the side supports that contacts the steel coil.

[0003] Chinese utility model patent application number 201220100326.8 discloses an arc-shaped bottom steel coil support frame, including a base and a pair of trapezoidal support members. Each pair of trapezoidal support members has an arc-shaped transition section at the connection point between its inner bottom and the base, forming an arc-shaped bottom opening between the pair of trapezoidal support members. The arc-shaped transition sections are interconnected to form an arc. Each pair of trapezoidal support members is a pair of hollow trapezoidal support members. Rubber pads are provided on the opposing surfaces of the pair of trapezoidal support members. Support blocks and hooks are provided on the base.

[0004] Existing steel coil support frames all have the advantages of high structural strength and easy stacking. However, when transporting steel coil support frames with forklifts, due to the low control precision of the forklifts, the fork teeth often scratch or even knock off the rubber pads. After the rubber pads are damaged, the steel coils are easily subjected to uneven stress, which affects the safety of transportation. At the same time, timely maintenance of the steel coil support frames is required, which increases the operating cost of steel coil transportation. Utility Model Content

[0005] The purpose of this invention is to provide a buffer pallet that prevents damage from forklift loading, overcoming the shortcomings of the prior art. Symmetrical double tail pads are provided on the inclined surface of the U-shaped groove on the centrally located hump base. The ends of the pads are in a free-floating and flat state, which can meet the buffering function when placing steel coils, and at the same time will not be easily damaged by the forklift teeth, thereby reducing maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A buffer pallet for preventing damage during forklift handling includes a hump base, end guards, side guards, corner protectors, lateral limiters, and side swing limiters. End guards are connected to both ends of the hump base along its length, and side guards are connected to both sides along its width. Lateral limiters and side swing limiters are symmetrically arranged on the two side guards. The hump base is composed of multiple parallel hump components that are narrower at the top and wider at the bottom. Adjacent hump components are fixedly connected by multiple reinforcing plate groups. Each hump component includes an upper hump plate, side hump plates, and a vertical hump plate. The three upper hump plates... Three U-shaped grooves should be formed, with an included angle of 27-32° between two side peak plates, an included angle of 21-25° between two vertical peak plates, and an included angle of 95-110° between two adjacent U-shaped grooves; the inclined surface of the upper peak plate is provided with anti-fork damage pads, including single tail pads at both ends and symmetrical double tail pads at the connection between adjacent U-shaped grooves. The symmetrical double tail pads are symmetrical about the middle mounting hole, and both ends are in a free-floating and flat state with the upper peak plate they belong to; one end of the single tail pad is connected to the upper peak plate through a connector, and the other end is in a free-floating and flat state with the upper peak plate it belongs to.

[0008] Furthermore, the lateral limiter includes a left limit seat, a right limit seat, and a limit angle steel section. The left and right limit seats are symmetrically arranged at both ends of the limit angle steel section. The left and right limit seats have the same structure, each including an upper top plate, a lower top plate, a side plate, and a longitudinal plate. The combined left and right limit seats form a symmetrically arranged triangular box shape.

[0009] Furthermore, the side swing limiter is an isosceles angle steel segment, which is fixedly connected to the outer side of the side protective frame in a snap-fit ​​state.

[0010] Furthermore, the end guard and / or side guard structure includes an outer cover box and inner stiffening plates. The outer cover box is a triangular or rectangular groove with one side open, and multiple inner stiffening plates are arranged and welded inside the outer cover box.

[0011] Furthermore, the included angle between the two vertical peak plates is 24°, the included angle between the two side peak plates is 30°, and the included angle between the two adjacent U-shaped grooves is 101°.

[0012] Furthermore, corner guards are connected to the four corners of the hump base, and hook plates are provided on the corner guards on both sides. The hook plates are inclined inward at an angle of 27-30° relative to the upper edge of the corner guard plate, and outward at an angle of 80-85°.

[0013] Furthermore, the reinforcing plate assembly includes an upper cover plate and a lower cover plate. The upper cover plate is connected to the lower cover plate at both ends by inclined plates to form a box-shaped reinforcing structure. A gap is provided between adjacent reinforcing plate assemblies to form a hollow groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) Symmetrical double tail pads are provided on the U-shaped groove slope of the hump base in the center position. The ends of the pads are symmetrically floating and lying flat, which can meet the buffering function when placing steel coils, and will not be easily damaged by the forklift forks, thereby reducing maintenance costs.

[0016] 2) The hump assembly, which is narrower at the top and wider at the bottom, has a more reasonable strength, which improves the overall structural strength of the frame, thus meeting the needs of railway safety production and also helping to reduce the self-weight of the frame.

[0017] 3) The combination of symmetrical double tail pads and single tail pads can be applied to various steel coil support structures, and is suitable for upgrading and transforming old steel coil support structures. It can adapt to various widths and specifications of strip steel and steel coils, ensuring the performance of the product. Attached Figure Description
