Description

Technical Field

[0001] The utility model belongs to the technical field of crawler shoes, in particular to a three-dimensional frame type skeleton and a crawler shoe. Background Art

[0002] In reality, polyurethane made of rubber or polyurethane has the characteristics of vibration absorption, abrasion resistance, and no damage to the working surface, and is increasingly applied to various mobile devices. The existing crawler shoes include two parts: a colloidal material and a steel internal member for connection. The steel internal member is placed inside the crawler shoe colloid. Its main function is as a steel member, and it can be used to assemble and fix the whole crawler shoe to related parts by fixing multiple fixing blocks or studs with internal or external threads.

[0003] The internal members of conventional crawler shoes are two independent long strip-shaped iron blocks, which are respectively placed at the corresponding assembly positions of the crawler shoes; they meet the positional relationship for overall assembly. The two independent long strip-shaped iron blocks do not form a whole and do not have the overall strength and rigidity of a frame structure. The pressure and shear force borne by the colloidal material of the crawler shoe are all borne by the colloidal material itself, resulting in the compressive and shear resistance performance of the crawler shoe being completely determined by the performance of the colloidal material itself. And this self-performance is limited by the material characteristics and there is no room for further improvement, resulting in lower overall performance and service life of the crawler shoe. For the conventional independent steel member, when subjected to pressure and shear force, due to its planar structure, insufficient self-strength and rigidity, it will deform, resulting in a reduction or failure of the overall performance of the crawler shoe.

The material of the colloid 1 can be selected as polyurethane or rubber, which is pressed and vulcanized by a special mold. It has a certain rigidity and strength, as well as wear resistance, and meets the performance of a walking part. The skeleton is a steel plate with an external and internal contour that is bent and pressed. Through multiple bending, a three-dimensional frame structure with grooves or flanges is formed to improve its overall bending resistance. The skeleton is embedded in the colloid 1 ( Figure 1 The frames of the skeleton are interlinked with each other, and there is no partition to hinder the one-piece molding of the colloid. When it is embedded in the track shoe colloid material, the colloid material can form a whole and completely wrap the skeleton, ensuring the overall strength of the rubber block. At the same time, with the support and support of the skeleton, the compression and shear resistance of the track shoe rubber block is further improved.

[0032] like Figures 2 to 5As shown in the figure, in the first embodiment, the three-dimensional frame-type skeleton 2 is formed by pressing a steel plate. It is formed by bending and pressing both sides of the steel plate, forming a flat plate part 2-1 and vertical flanges 2-2 that longitudinally penetrate the length on both sides of the flat plate part 2-1. A notch 2-8 is provided in the middle of the vertical flange 2-2. The whole skeleton forms a three-dimensional frame structure, achieving greater bending strength and rigidity. Before pressing the steel plate, it has an external cutting profile, with a notch provided at the side of the steel plate, and at the same time has an internal cutting profile, with a hollow 2-3 provided in the middle of the steel plate.

The flat plate part 2-1 is embedded inside the rubber block 1-1, and the vertical flanges 2-2 on both sides are respectively embedded inside the protrusions 1-2, improving the bending resistance of the colloid 1 through the flat plate part 2-1 and the vertical flanges 2-2. The bolt groove 1-3 in the middle of the protrusion 1-2 matches the notch 2-8 of the vertical flange 2-2 to avoid the fastening bolts of related parts. The connecting holes 1-4 at both ends of the protrusion 1-2 match the connecting columns 2-4 on the flat plate part 2-1, and the connecting columns 2-4 install the whole track plate on related parts through the connecting holes 1-4.

After being pressed according to the designed shape, a groove 2-5 is formed in the middle of the steel plate, and a notch 2-8 required for the function is formed at the side of the steel plate. The notch 2-8 is provided to avoid the fastening bolts of related parts.

[0036] Through holes 2-7 are opened at both ends of the horizontal flange 2-6, and connecting columns 2-4 are welded and installed on the through holes 2-7. In this embodiment, the connecting column 2-4 is a fixed bolt or a cylindrical column with internal threads, which is used to realize the assembly function of fixing the whole crawler plate on related parts.
