Description

Technical Field

[0001] This utility model relates to the field of chain conveyor technology, and in particular to a polymer wear-resistant and impact-resistant guide rail for chain conveyors. Background Technology

[0002] Heavy-duty chain conveyors are widely used continuous conveying equipment in industries such as metallurgy, mining, and building materials. During material conveying, overweight materials (such as scrapped cars, large metal components, and large pieces of ore) need to be recycled or crushed. In this process, guide rails are added under the chain plates to help withstand the impact of large, heavy objects on the chain plates and prevent deformation.

[0003] Traditional chain plate lower guide rails mostly use steel tracks in conjunction with lower support rails. The lower wear-resistant guide rails are mostly made of wear-resistant steel or steel rails, resulting in high frictional resistance. During the material conveying process, the steel track and the lower guide plate of the chain plate are in a state of hard wear.

[0004] Traditional steel tracks and lower guide plates of chain plates do not provide cushioning and shock absorption. Over time, the lower guide plates of chain plates will wear and thin, and the deformation of the chain plates will gradually increase after being impacted by materials, affecting the normal and stable operation of the equipment. At the same time, because the static friction coefficient between the lower guide plate of the chain plate and the steel rail is relatively large, the friction loss generated when the operating load is large will be large, which will increase the driving force, i.e., increase the energy consumption of the motor and increase the operating cost. Summary of the Invention

[0005] The purpose of this utility model is to provide a polymer wear-resistant and impact-resistant guide rail for chain conveyors. This guide rail, through the use of a polymer wear-resistant and impact-resistant guide plate in conjunction with a support rail assembly, exhibits a greater shock absorption effect than traditional wear-resistant steel rails due to the molecular structure characteristics of the polymer wear-resistant and impact-resistant guide plate. Furthermore, because the coefficient of friction between the polymer wear-resistant and impact-resistant guide plate and the metal T-shaped plate's lower sliding plate is relatively low, the resistance loss generated by sliding friction is also smaller. This reduces the required driving force of the equipment and the power requirement of the drive motor, thereby lowering its operating costs and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polymer wear-resistant and impact-resistant guide rail for a chain conveyor, comprising a chain conveyor, wherein a polymer wear-resistant and impact-resistant guide plate is installed inside the chain conveyor, a support rail assembly is installed below the polymer wear-resistant and impact-resistant guide plate, a T-shaped chain plate assembly is arranged above the polymer wear-resistant and impact-resistant guide plate, and a T-shaped plate underplate is arranged between the T-shaped chain plate assembly and the polymer wear-resistant and impact-resistant guide plate;

[0007] The rail assembly includes a rail body, and reinforcing ribs are provided on both the left and right sides of the rail body.

[0008] Preferably, the main body of the rail is made of I-beams and H-beams, and a connecting bolt is provided at the connection between the upper flange of the main body of the rail and the polymer wear-resistant and impact-resistant guide plate, the connecting bolt locking the main body of the rail and the polymer wear-resistant and impact-resistant guide plate.

[0009] Preferably, the reinforcing ribs are located on both sides of the web of the rail body, and the reinforcing ribs are evenly distributed at equal intervals along the axial direction of the rail body.

[0010] Preferably, a frame crossbeam is provided below the rail assembly, and frame longitudinal beams are provided on the left and right sides below the frame crossbeam. The rail assemblies are evenly distributed at equal intervals along the axial direction of the frame crossbeam.

[0011] Preferably, a steel structure support is provided below the longitudinal beam of the frame, and the main body of the support rail is welded above the crossbeam of the frame.

[0012] Preferably, the gap between the T-shaped lower slide plate and the polymer wear-resistant and impact-resistant guide plate is 0-1.5mm, and the polymer wear-resistant and impact-resistant guide plate is made of polyester polyurethane material.

[0013] Preferably, material baffles for guide troughs are provided on the left and right sides above the T-shaped chain plate assembly, and overflow skirts are provided on the outer side of the steel structure support.

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

[0015] 1. By using a high-polymer wear-resistant and impact-resistant guide plate in conjunction with a rail assembly, the shock absorption effect of the high-polymer wear-resistant and impact-resistant guide plate is greater than that of traditional wear-resistant steel rails due to the molecular structure characteristics of the guide plate. At the same time, because the coefficient of friction between the high-polymer wear-resistant and impact-resistant guide plate and the metal T-shaped plate slide plate is small, the resistance loss generated by sliding friction is also small, which reduces the driving force required for the equipment and the power requirement of the drive motor, thus reducing its operating cost.

[0016] 2. Reinforcing ribs can be welded to the outside of the main body of the guide rail. The reinforcing ribs are distributed according to the actual length of the main body of the guide rail, which can play a strengthening role and thus improve the impact resistance of the guide rail.

Detailed Implementation

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 5A polymer wear-resistant and impact-resistant guide rail for a chain conveyor includes a chain conveyor 3, a polymer wear-resistant and impact-resistant guide plate 1 installed inside the chain conveyor 3, a support rail assembly 2 installed below the polymer wear-resistant and impact-resistant guide plate 1, a T-shaped chain plate assembly 4 arranged above the polymer wear-resistant and impact-resistant guide plate 1, and a T-shaped plate lower slide plate 9 arranged between the T-shaped chain plate assembly 4 and the polymer wear-resistant and impact-resistant guide plate 1;

[0028] The rail assembly 2 includes a rail body 201, and reinforcing ribs 202 are provided on both the left and right sides of the rail body 201.

[0029] The main body 201 of the rail is made of I-beams and H-beams. A connecting bolt 10 is provided at the connection between the upper flange of the main body 201 and the polymer wear-resistant and impact-resistant guide plate 1. The connecting bolt 10 locks the main body 201 of the rail and the polymer wear-resistant and impact-resistant guide plate 1.

[0030] The reinforcing ribs 202 are located on both sides of the web of the rail body 201, and the reinforcing ribs 202 are evenly distributed at equal intervals along the axial direction of the rail body 201.

[0031] By adopting the above technical solution, the traditional steel rail and the T-shaped plate underslide 9 are in rigid contact, and the two wear each other quickly. Although it is impact-resistant, it does not buffer the impact force. The impact load will be transmitted to the steel structure support 7 and the foundation. In contrast, the polymer wear-resistant and impact-resistant guide plate 1 is made of polyester polyurethane. Polyester polyurethane is a polyurethane resin synthesized by chemical reaction of polyester polyol and polyisocyanate. It has high mechanical strength, wear resistance, oil resistance and tear resistance. The polymer wear-resistant and impact-resistant guide plate 1 is used in conjunction with the main body of the rail 201. Due to the molecular structure characteristics of the polymer wear-resistant and impact-resistant guide plate 1, its shock absorption effect is greater than that of the traditional wear-resistant steel rail. Because its wear resistance and fatigue resistance are also better, the wear amount between it and the T-shaped plate underslide 9 is also smaller per unit time. In this way, the equipment can operate stably for a longer period of time.

[0032] Specifically, such as Figures 1 to 4 As shown, a frame beam 5 is provided below the rail assembly 2, and frame longitudinal beams 8 are provided on the left and right sides below the frame beam 5. The rail assembly 2 is evenly distributed at equal intervals along the axial direction of the frame beam 5.

[0033] A steel structure support 7 is installed below the longitudinal beam 8 of the frame, and the main body of the support rail 201 is welded above the cross beam 5 of the frame.

[0034] The gap between the T-shaped lower slide plate 9 and the polymer wear-resistant and impact-resistant guide plate 1 ranges from 0 to 1.5 mm. The polymer wear-resistant and impact-resistant guide plate 1 is made of polyester polyurethane material, which not only buffers the impact of large and heavy materials on the chain plate, but also, due to its molecular structure characteristics, its shock absorption effect is far superior to that of traditional ordinary wear-resistant steel guide rails. Furthermore, its wear resistance and fatigue resistance are also better, and the amount of wear between it and the lower slide plate of the chain plate per unit time is much smaller, so the equipment can operate stably for a longer period of time. Material baffles 11 are provided on the left and right sides above the T-shaped chain plate assembly 4, and overflow skirts 6 are provided on the outer side of the steel structure support 7.

[0035] By adopting the above technical solution, the number of T-shaped chain plates arranged below the T-shaped chain plate assembly 4 is determined according to the equipment specifications. The laying height is considered based on the point where the interaction between the T-shaped plate under the sliding plate 9 and the polymer wear-resistant and impact-resistant guide plate 1 is zero. The actual assembly gap is difficult to reach zero, and a 0-1.5mm installation gap is generally considered. The rail support assembly 2 can use I-beams or H-beams as the rail support body 201. The rail support body 201 is welded and fixed to the frame beam 5. The web of the rail support body 201 is reinforced on both sides according to the actual situation, and reinforcing ribs 202 are welded to further strengthen it, thereby improving the impact resistance of the guide rail. Due to the surface of the polymer material and the metal T-shaped plate under the sliding plate, the interaction between the sliding plate and the guide plate is zero. The friction coefficient of the contact between the sliding plate 9 and the metal T-shaped plate is much smaller, resulting in less resistance loss due to sliding friction. This reduces the required driving force of the equipment and the power requirement of the drive motor, thus lowering its operating costs. The combination of the polymer wear-resistant and impact-resistant guide plate 1 and the rail assembly 2, due to the molecular structure characteristics of the polymer wear-resistant and impact-resistant guide plate 1, provides a greater shock absorption effect than traditional wear-resistant steel rails. Furthermore, because the friction coefficient between the polymer wear-resistant and impact-resistant guide plate 1 and the metal T-shaped plate under the sliding plate 9 is small, the resistance loss due to sliding friction is also smaller, further reducing the required driving force of the equipment and the power requirement of the drive motor, thus lowering its operating costs.

[0036] Working Principle: The polymer wear-resistant and impact-resistant guide plate 1 is made of polyester polyurethane material and is placed below the T-shaped chain plate assembly 4. The number of plates is determined according to the equipment specifications. The laying height is based on the point where the interaction between the T-shaped plate underslide 9 and the polymer wear-resistant and impact-resistant guide plate 1 is zero. In practice, it is difficult to achieve zero gap, and a 0-1.5mm installation gap is generally considered. The rail assembly 2 can use I-beams or H-beams as the rail body 201. The rail body 201 is welded and fixed to the frame beam 5. The web of the rail body 201 is reinforced on both sides according to the actual situation, and reinforced ribs 202 are welded to further strengthen it and improve the impact resistance of the guide rail. The polymer wear-resistant and impact-resistant guide plate 1 is used in conjunction with the rail body 201. Due to the molecular structure characteristics of the polymer wear-resistant and impact-resistant guide plate 1, its shock absorption effect is greater than that of traditional wear-resistant steel rails. Because of its superior wear resistance and fatigue resistance, the wear amount per unit time between the guide plate 1 and the T-shaped plate underslide 9 is also smaller, so the equipment can operate stably for a longer period of time.

[0037] 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.
