Description

Technical Field

[0001] The utility model relates to the technical field of boom storage, in particular to a boom anti-dumping storage tool and an anti-dumping component. Background Art

[0002] After the excavator boom is welded and before the whole machine is assembled, the boom needs to be stored separately or in a centralized storage waiting for the whole machine to be assembled and used. Figure 1 As shown, the boom includes a front fork and a rear seat, and the conventional storage method is vertical, such as Figure 2 , Figure 3 As shown in the figure (where the bottom horizontal line represents the ground), the front fork and the rear seat are placed in contact with the ground.

[0003] During normal storage, the center of gravity of the boom is within the dumping point. Figure 4 As shown, G is gravity, L1 is the anti-tilt arm, and the anti-tilt moment is G×L1.

[0031] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0032] Example 1

[0033] As introduced in the background technology, the boom is stored vertically, with the front fork and the rear seat touching the ground. When the boom is stored normally, it relies on its own gravity to prevent tipping, and there is no anti-tip measure. When there is an external force or a large inertia, there is a risk of tipping when the tipping moment F×L2> the anti-tip moment G×L1. The anti-tip moment G×L1 is a fixed value, and the tipping arm L2 is much larger than the anti-tip arm L1, so a very small tipping force F is required to cause the boom to tip. In order to solve the above technical problems, this embodiment proposes a tooling for anti-tip storage of the boom.

[0034] like Figure 6 As shown, the storage tooling includes a bottom plate 1, a guide top plate 2 and a connecting plate 4; the bottom plate 1 is a flat plate, and the flat bottom plate 1 ensures sufficient contact area on the basis of lightness, thereby improving stability. The guide top plates 2 have two, which are arranged in pairs on both sides of the top surface of the bottom plate 1, and the guide top plates 2 are arranged opposite to each other and the distance between the guide top plates 2 matches the thickness of the movable arm. Matching means that the distance between the guide top plates 2 is equal to the thickness of the movable arm, or the distance between the guide top plates 2 is slightly greater than the thickness of the movable arm.

[0035] The guide top plate 2 has a set distance from the end of the bottom plate 1, that is, the guide top plate 2 is not arranged at the end of the top plate, but is a certain distance inside. Figure 6 The connecting plate 4 is provided at the left end of the middle part, and the outer end of the connecting plate 4 is provided with a connecting hole. Figure 6 A connecting column 5 is provided at the middle right end, and the connecting column 5 can be inserted into the connecting hole of another storage tooling connecting plate 4.

[0036] When using the storage tool Figure 7 As shown, the boom is hoisted or transported by forklift to the top of the tooling, the rear seat is aligned with the center of the two guide top plates 2, and the boom is slowly placed into the tooling. By using the tooling, the boom anti-tilt arm L1 is extended, thereby increasing the tipping force F during tipping. Therefore, greater force is required for tipping, reducing the risk of boom tipping (tipover occurs when F↑×L2>G×L1↑).

[0037] In addition, through the cooperation of the connecting plate 4 and the connecting column 5, multiple storage tools can be used in combination. When multiple tools are used in combination, the distance of the anti-tilt force arm is infinitely extended, eliminating the risk of the boom tipping and avoiding the sliding of the boom and the tooling, which is convenient for the 5S management of the production site and the placement is standardized and orderly.

[0038] The guide top plate 2 includes a vertical plate and a guide part, the vertical plate is fixed on the bottom plate 1, the guide part is arranged at the top of the vertical plate and is located on the side of the guide top plate 2 facing the opposite guide top plate 2, the distance between the bottom ends of the two guide parts is equal to the distance between the two vertical plates, and the distance between the top ends of the two guide parts is greater than the distance between the two vertical plates. By arranging the guide part on the top of the guide top plate 2, it can be used as a guide positioning to facilitate the installation of the boom.

[0039] The guide portion may be an arc-shaped structure, such as Figure 6 As shown, the arc structure bends upward and outward from the top of the vertical plate. Of course, it can be understood that the guide part can also be arranged in an inclined plate style, that is, the guide parts on both sides are arranged in an inverted eight-shaped shape.

[0040] like Figure 6 As shown, the storage tooling also includes a reinforcing plate 3, which is a triangular structure. The bottom edge of the reinforcing plate 3 is fixed on the bottom plate 1, and the vertical edge of the reinforcing plate is fixedly connected to the outer side surface of the top plate. The strength of the guide top plate 2 and the connection strength with the bottom plate 1 are enhanced by the arrangement of the reinforcing plate 3, so as to prevent the guide top plate 2 from bending or breaking when the boom is subjected to external force.

[0041] The number of reinforcing plates 3 can be selected according to the specific situation. In this embodiment, Figure 6 As shown, each guide top plate 2 is provided with a pair of reinforcing plates 3, which are respectively located at the two ends of the outer side of the guide top plate 2, and the distance between the outer sides of the pair of reinforcing plates 3 is equal to the width of the bottom plate 1. The reinforcing plates 3 are welded to the bottom plate 1 and the guide top plate 2, and the connection strength of each plate is enhanced by welding.

[0042] The reinforcing plate 3 is provided with holes, which penetrate through the thickness direction of the reinforcing plate 3. The holes may be a plurality of small holes arranged in the middle area of ​​the reinforcing plate 3, or may be a plurality of small holes arranged in the middle area of ​​the reinforcing plate 3. Figure 6 As shown, a large triangular hole is located in the middle. By opening a hole in the reinforcing plate 3, it is convenient for tooling hoisting or forklift transportation while reducing weight.

[0043] like Figure 6 As shown, the connecting plate 4 is fixed on the top surface of the bottom plate 1, and one end of the connecting plate 4 protrudes out of the bottom plate 1, and the width of the connecting plate 4 is less than the distance between a pair of reinforcing plates 3. At the same time, the axis of the connecting hole and the axis of the connecting column 5 are both vertically arranged, and the distance between the axis of the connecting hole and the first end of the bottom plate 1 is equal to the distance between the axis of the connecting column 5 and the second end of the bottom plate 1. Through the cooperation of the connecting plate 4 (connecting hole) and the connecting column 5, multiple tooling can be conveniently connected and combined.

[0044] Example 2

[0045] This embodiment proposes an anti-dumping assembly, including at least two boom anti-dumping storage fixtures as described in Embodiment 1, such as Figure 8 As shown, all storage fixtures are arranged in sequence along a direction perpendicular to the guide top plate 2, and among two adjacent storage fixtures, the connecting column 5 of one storage fixture is inserted into the connecting hole of the other storage fixture.

[0046] When the tooling is used in combination, align the connection hole of the connecting plate 4 of the tooling with the connection column 5 of another tooling to combine, and connect them in sequence according to the number of placements. Lift the boom to the top of the tooling in sequence or transport it by forklift, align the rear seat with the center of the two guide top plates 2, and slowly put the boom into the tooling. By using multiple sets of tooling in coordination, the anti-tilt arm can be infinitely extended, further eliminating the risk of the boom tipping. It also avoids the sliding of the boom and tooling, facilitates the 5S management of the production site, and places the boom in an orderly manner.

[0047] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
