Description

Technical Field

[0001] This utility model relates to the field of bulk material conveying technology, and in particular to an impact-resistant T-shaped plate for heavy-duty chain conveyors. Background Technology

[0002] Chain conveyors are widely used continuous conveying equipment in industries such as metallurgy, mining, and building materials. During material transport, heavy materials (such as scrapped cars, large metal components, and large blocks of ore) need to be recycled or crushed, requiring the chain conveyor to feed continuously and evenly. However, the commonly used ordinary apron (i.e., chain plate) has a significant drawback: when heavy scrap steel materials (up to several tons per batch) are thrown directly onto the chain plate surface from a height, a huge instantaneous impact force is generated.

[0003] Because ordinary scale structures are relatively simple, their rigidity and impact resistance are insufficient, leading to the following problems: 1. Severe deformation of the chain plate: The huge impact force causes the chain plate to bend or twist plastically, making it impossible to return to its original shape and operate normally.

[0004] 2. Increased wear: The contact state between the deformed chain plate and the conveyor guide rail deteriorates, changing from surface contact to point contact or line contact, resulting in a sharp increase in contact stress, which intensifies the wear of the chain plate itself and the guide rail.

[0005] 3. Increased power consumption: Deformation and wear increase operating resistance, leading to increased load on the drive motor and increased energy consumption.

[0006] 4. Shortened service life: Frequent impacts and abnormal wear significantly shorten the maintenance cycle and service life of the chain plate and the entire conveyor, increasing the cost of equipment use and maintenance. Summary of the Invention

[0007] The purpose of this invention is to provide an impact-resistant T-shaped plate for heavy-duty chain conveyors. It uses H-beams as the main beam and rectangular impact-resistant members on both sides as secondary beams, forming a high-rigidity composite beam structure. When a heavy object falls, the impact force is dispersed and absorbed by the H-beams, rectangular impact-resistant members, and reinforcing ribs, minimizing plastic deformation of the base plate. Because the T-shaped plate itself is not easily deformed, its lower sliding plate maintains good surface contact with the guide rail, avoiding uneven wear and pitting caused by deformation. This significantly reduces the wear rate between the sliding plate and the guide rail, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant T-shaped plate for heavy-duty chain conveyors, including a base plate as the basic load-bearing plate of the entire T-shaped plate; H-beams, with their lower flanges vertically welded to the center area of ​​the lower surface of the base plate, serve as the main longitudinal reinforcing beams; A rectangular impact-resistant component, parallel to the H-beam and welded to the upper surface of the base plate; Reinforcing ribs are vertically arranged on both sides of the web of the H-beam and welded and fixed to the flanges of the H-beam respectively. The sliding plate is welded and fixed to the lower surface of the H-beam and is used to slide in contact with the guide rail of the chain conveyor. A sealing plate is provided at the lower surface edge of the base plate to prevent material leakage.

[0009] Preferably, the number of the rectangular impact-resistant components can be set to two or more, and the rectangular impact-resistant components are symmetrically welded to the left and right sides of the upper surface of the base plate.

[0010] Preferably, the reinforcing rib is a right-angled trapezoidal plate or a triangular plate, and there are multiple reinforcing ribs, which are evenly distributed along the length of the H-beam.

[0011] Preferably, the H-beam, the rectangular impact-resistant component, and the upper surface of the base plate together form a multi-layered composite load-bearing surface for directly bearing the impact load of the material.

[0012] Preferably, the sealing plate is perpendicular to the lower surface of the base plate and extends downward.

[0013] Preferably, the skateboard is made of a wear-resistant material, such as high manganese steel or wear-resistant alloy steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses H-beams as the main beam and rectangular impact-resistant members on both sides as secondary beams to form a high-rigidity composite beam structure. When a heavy object falls, the impact force is dispersed and absorbed by the H-beams, rectangular impact-resistant members, and dense reinforcing ribs, which greatly avoids plastic deformation of the base plate. Since the T-plate itself is not easily deformed, the sliding plate under it can always maintain good surface contact with the guide rail, avoiding uneven wear and pitting caused by deformation, thereby significantly reducing the wear rate of the sliding plate and the guide rail. 2. The flat and unchanging surface of the chain plate in this invention ensures the stability of material conveying, reduces operating resistance, and thus lowers the power consumption of the drive unit, achieving energy-saving operation. It fundamentally solves the problems of chain plate deformation and abnormal wear, greatly extending the service life of the T-plate itself and key components such as the chain conveyor guide rail, reducing downtime and maintenance time and operating costs. All components use conventional profiles and plates, connected by welding, resulting in a simple, reliable structure that is easy to manufacture and assemble. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution: Please see Figures 1 to 3 An impact-resistant T-shaped plate for heavy-duty chain conveyors includes a base plate 1, serving as the basic load-bearing plate for the entire T-shaped plate; an H-beam 4, the lower flange of which is vertically welded to the center area of ​​the lower surface of the base plate 1, serving as the main longitudinal reinforcing beam; a rectangular impact-resistant member 6, parallel to the H-beam 4 and welded to the upper surface of the base plate 1; reinforcing ribs 5, vertically arranged on both sides of the web of the H-beam 4 and welded and fixed to the flanges of the H-beam 4 respectively; a sliding plate 3, welded and fixed to the lower surface of the H-beam 4, for sliding in contact with the guide rail of the chain conveyor; and a sealing plate 2, disposed on the lower edge of the base plate 1, for preventing material leakage.

[0020] The number of rectangular impact-resistant components 6 can be set to two or more. The rectangular impact-resistant components 6 are symmetrically welded to the left and right sides of the upper surface of the base plate 1. The structure of the reinforcing rib 5 is a right-angled trapezoidal plate or a triangular plate. The number of reinforcing ribs 5 is set to multiple and evenly distributed along the length direction of the H-beam 4. The H-beam 4, the rectangular impact-resistant components 6 and the upper surface of the base plate 1 together form a multi-layered composite load-bearing surface for directly bearing the impact load of the material. The sealing plate 2 is perpendicular to the lower surface of the base plate 1 and extends downward. The material of the sliding plate 3 is a wear-resistant material, such as high manganese steel or wear-resistant alloy steel.

[0021] By adopting the above technical solution, the main body of the base plate 1 is made of a rectangular steel plate. An H-beam 4 is welded on the longitudinal center line of the lower surface of the base plate 1. The specifications of the H-beam 4 can be selected according to the magnitude of the impact load. On both sides of the upper end face of the base plate 1, two rectangular impact-resistant members 6 are symmetrically welded. The rectangular impact-resistant members 6 are parallel to the H-beam 4. On both sides of the web of the H-beam 4, a set of reinforcing ribs 5 are welded at certain intervals. In this embodiment, the reinforcing ribs 5 are made of right-angled trapezoidal steel plates. Their lower bottom edge is welded to the base plate 1, and their vertical waist edge is welded to the lower flange of the H-beam 4, thereby forming a stable triangular support structure. On the lower surface of the H-beam 4, a sliding plate 3 is fixed by welding. The sliding plate 3 can be made of a material with better wear resistance than the base plate 1, such as NM400 wear-resistant steel. In this embodiment, sealing plates 2 extending downward can also be welded to both sides of the lower surface of the base plate 1. These plates are used to overlap with the sealing plates 2 of the adjacent T-shaped plates when assembled into a conveyor belt to form a seal. A high-rigidity composite beam structure is formed by using H-beams 4 as the main beam and rectangular impact-resistant members 6 on both sides as secondary beams. When a heavy object falls, the impact force is dispersed and absorbed by the H-beams 4, rectangular impact-resistant members 6, and reinforcing ribs 5, minimizing plastic deformation of the base plate 1. Since the T-plate itself is not easily deformed, the sliding plate 3 at its lower part can always maintain good surface contact with the guide rail, avoiding uneven wear and pitting caused by deformation. This significantly reduces the wear rate between the sliding plate 3 and the guide rail. The flat and unchanging chain plate surface ensures the stability of material conveying, reduces running resistance, and thus reduces the power consumption of the drive unit, achieving energy-saving operation. This fundamentally solves the problems of chain plate deformation and abnormal wear, greatly extending the service life of the T-plate itself and key components such as the chain conveyor guide rail, reducing downtime and maintenance time and operating costs. All components use conventional profiles and plates, connected by welding, resulting in a simple, reliable structure that is easy to manufacture and assemble.

[0022] In operation, the chain conveyor operates, and heavy materials fall from a height onto the surface of the T-shaped plate. The impact force first acts on the composite load-bearing surface composed of H-beams 4, rectangular impact-resistant members 6, and the base plate 1. H-beams 4, acting as the main beam, bear most of the impact bending moment; the rectangular impact-resistant members 6 on both sides act as auxiliary longitudinal beams, effectively preventing the base plate 1 from denting or deforming in the areas on both sides of H-beams 4; while the evenly distributed reinforcing ribs 5 ensure the local stability of H-beams 4, preventing buckling of its web. Through this multi-layered structural design, the impact energy is quickly dispersed throughout the entire T-shaped plate frame, avoiding stress concentration, thus ensuring that the T-shaped plate maintains its shape stability and performs its conveying function normally under harsh working conditions of long-term, heavy loads, and strong impacts.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
