Description

Technical Field

[0001] This utility model belongs to the technical field of excavator components, specifically relating to an excavator anti-slip track plate. Background Technology

[0002] During excavator operation, the track shoes, as a key component of its walking system, directly contact the ground and provide traction. However, the anti-slip performance of existing excavator track shoes is insufficient to meet actual needs in complex and harsh working environments. For example, in muddy, soft, or snow-covered terrain, the friction between the track shoes and the ground is insufficient, making slippage very likely. This not only makes it difficult for the excavator to move, affecting work efficiency and increasing energy consumption, but may also cause the excavator to get stuck, or even lead to safety accidents, bringing great inconvenience and potential risks to construction.

[0003] Therefore, there is an urgent need to provide an anti-skid track pad for excavators to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-slip track plate for excavators, so as to solve the technical problem that the anti-slip performance of existing excavator track plates is difficult to meet the actual needs in complex and harsh working environments.

[0005] To solve the above-mentioned technical problems, this utility model provides an anti-slip track plate for excavators, comprising: a track plate body, wherein the track plate body is provided with a grid groove, and conical teeth are provided in the complete quadrilateral area enclosed by the grid groove; the track plate body includes a base layer and an anti-slip layer, wherein the grid groove and the conical teeth are both placed on the surface of the anti-slip layer.

[0006] As further explained, the inclination angle of the grid groove is 45°, and the conical teeth are evenly distributed within the complete quadrilateral area enclosed by the grid groove.

[0007] As further explained, the conical teeth are made of tungsten-cobalt alloy.

[0008] As further explained, the base layer is made of low-alloy high-strength steel, the anti-slip layer is made of high-chromium cast iron, and the anti-slip layer is welded on top of the base layer.

[0009] As further explained, the base layer is provided with reinforcing ribs.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The grid grooves on the surface of the anti-slip layer of the track plate, along with the conical teeth within the quadrilateral area enclosed by the grid grooves, significantly increase the contact area and friction between the track plate and the ground. In complex terrains such as muddy, soft, or snow-covered areas, the conical teeth can penetrate deep into the ground, and the grid grooves further hinder relative sliding between the track plate and the ground. This effectively solves the problem of insufficient anti-slip performance and easy slippage of existing track plates in these harsh environments, thereby improving the stability and operating efficiency of the excavator and reducing the increase in energy consumption caused by slippage.

[0012] 2. The conical teeth are made of tungsten-cobalt alloy, possessing high hardness, high wear resistance, and good toughness. They maintain shape stability under intense friction with the ground and complex stress conditions, resisting wear and damage, thus extending the service life of the conical teeth and ensuring the long-term anti-slip performance of the track shoes. The base layer uses low-alloy high-strength steel, providing the overall structural strength of the track shoes, enabling them to withstand the weight of the excavator and various external forces during operation. The anti-slip layer is made of high-chromium cast iron and fixed to the base layer by welding. High-chromium cast iron not only has excellent wear resistance but also bonds tightly with the base layer, forming a robust whole, improving the track shoes' resistance to deformation and durability.

[0013] 3. The 45° inclined angle design of the grid grooves allows the track plates to distribute pressure more evenly when under stress, avoiding stress concentration and improving the structural stability of the track plates; the reinforcing ribs set in the base layer further enhance the rigidity of the track plates, reduce their deformation when traveling on complex terrain, ensure good cooperation between the track plates and components such as drive wheels and track rollers, reduce the risk of failure caused by track plate deformation, and improve the overall reliability of the excavator's travel system.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figure 1-2 An excavator anti-slip track plate includes: a track plate body 1, with a grid groove 2 on the track plate body 1, and conical teeth 3 within each complete quadrilateral area enclosed by the grid groove 2. The track plate body 1 includes a base layer 101 and an anti-slip layer 102, with the grid groove 2 and conical teeth 3 both placed on the surface of the anti-slip layer 102. In complex terrains such as muddy, soft, or snow-covered areas, the conical teeth 3 can penetrate deep into the ground, and the grid groove 2 can further hinder the relative sliding between the track plate and the ground, effectively solving the problem of insufficient anti-slip performance and easy slippage of existing track plates in these harsh environments. This improves the stability and operating efficiency of the excavator and reduces the increase in energy consumption caused by slippage.

[0023] like Figure 1 As shown, the inclination angle of the grid groove 2 is 45°, and the conical teeth 3 are evenly distributed within the complete quadrilateral area enclosed by the grid groove 1. This allows the track plate to distribute pressure more evenly when under stress, avoids stress concentration, and improves the structural stability of the track plate.

[0024] like Figure 1 As shown, the conical tooth 3 is made of tungsten-cobalt alloy. It has high hardness, high wear resistance and good toughness, and can maintain its shape stability under severe friction with the ground and complex stress conditions. It is not easy to wear and damage, which extends the service life of the conical tooth 3 and thus ensures the long-term anti-slip performance of the track plate.

[0025] like Figure 2As shown, the base layer 101 is made of low-alloy high-strength steel, and the anti-slip layer 102 is made of high-chromium cast iron. The anti-slip layer 102 is welded onto the base layer 101. The base layer 101, made of low-alloy high-strength steel, provides structural strength to the track shoe body 1, enabling it to withstand the weight of the excavator and various external forces during operation. The anti-slip layer 102, made of high-chromium cast iron, is fixed to the base layer 101 by welding. High-chromium cast iron not only has excellent wear resistance but also bonds tightly with the base layer 101, forming a robust whole and improving the deformation resistance and durability of the track shoe body 1.

[0026] like Figure 2 As shown, the base layer 101 is equipped with reinforcing ribs 4. This further enhances the rigidity of the track plate body 1, reduces its deformation when traveling on complex terrain, ensures good fit between the track plate and components such as drive wheels and track rollers, reduces the risk of failure caused by track plate deformation, and improves the overall reliability of the excavator's travel system.
