Description

Technical Field

[0001] The utility model belongs to the field of coal transportation equipment, in particular to a three-dimensional scraper chain track. Background Art

[0002] Traditional scraper designs suffer from numerous flaws, primarily in the layout and operation of the chain, scrapers, runway, and support structure. Typically, the chain and scrapers of a scraper run directly on the runway and iron support. While this design is simple and easy to operate, it can expose a range of issues over time.

[0003] First, debris such as the scraper runway and coal deposits severely wear the chain. Because the chain is in direct contact with the runway, and the scraper operating environment is often harsh, impurities such as coal and dust easily accumulate on the runway, further exacerbating chain wear. This not only significantly shortens the chain's service life but also increases the frequency of maintenance and replacement, thereby increasing maintenance costs.

[0004] Secondly, when the scraper chain runs on the runway, the guide rails or sprockets are misaligned, causing the chain to not follow the intended trajectory, which can easily lead to chain skew and chain drift. Furthermore, due to long-term high-load operation, the scraper chain wears out rapidly, and maintenance and replacement are frequent. Each chain replacement results in a large amount of material waste, increasing the company's operating costs. Frequent replacement and maintenance work also increases the labor intensity of workers, further affecting the normal operation of the equipment. Due to these issues, the design of the old scraper conveyor urgently needs to be improved to reduce chain wear, improve the equipment's operating stability, and reduce maintenance frequency and material consumption. Utility Model Content

[0005] The purpose of this utility model is to provide a three-dimensional scraper chain track to solve the problem that the existing chain is in direct contact with the runway and the working environment of the scraper is usually harsh, which greatly shortens the service life of the chain and increases the frequency of maintenance and replacement.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a three-dimensional scraper chain track, comprising a support frame and a runway, wherein the runway is installed inside the support frame and has gaps with the support frame on both sides; a scraper is provided on the upper part of the runway, and the scraper is connected to a chain; the chain drives the scraper to move along the runway through the drive of a power device.

[0007] Preferably, the runway includes an upper runway and a lower runway, the upper runway is installed on the upper part of the support frame, and the lower runway is installed on the lower part of the support frame.

[0008] Preferably, a cross brace is provided at the lower portion of the upper runway.

[0009] Preferably, the cross brace is arranged along the length direction of the upper runway.

[0010] Preferably, the cross brace is perpendicular to the movement direction of the upper runway.

[0011] Preferably, the distance between two adjacent cross braces is 1200-1300 mm.

[0012] Compared with the existing technology, the present invention has the following beneficial effects: 1. Reduced wear between the chain and the runway: In traditional scraper conveyors, the chain is in direct contact with the runway, which is easily affected by impurities such as coal accumulation and dust, resulting in increased wear. The present invention provides a certain gap (hollowed-out portion) between the support frame and the runway, allowing the chain to run in an independent channel, avoiding direct friction between the chain and the runway and significantly reducing chain wear.

[0013] The chain drives the scraper to move more smoothly, avoiding chain tilt and chain drift. The stable operation of the chain in the hollow channel reduces the displacement of the chain due to vibration, ensuring that the scraper can run smoothly along the runway, thereby improving conveying efficiency and the overall stability of the equipment.

[0014] Because chain and scraper wear is significantly reduced, the service life of the equipment is extended and the frequency of maintenance and replacement is significantly reduced. This not only reduces the maintenance workload and downtime for workers, but also reduces the material waste caused by frequent component replacement, further improving the economic and environmental benefits of the equipment.

[0015] The equipment's operational stability and efficiency have been significantly improved. The equipment's smooth operation and reduced wear allow the scraper to operate for extended periods under high load conditions, reducing the occurrence of unexpected failures and ensuring production continuity.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] As shown in the figure, the present invention provides a three-dimensional scraper chain track, including a support frame 1, a runway, a scraper 4 and a chain 5. The three-dimensional scraper chain track improves the working efficiency and service life of the equipment through the optimized structural design, reduces wear and instability during operation. The structural features and operation mode of the present invention are described in detail below with reference to specific embodiments.

[0021] The main structure of the three-dimensional scraper chain track consists of a support frame 1 and a runway. The support frame 1 is the load-bearing and fixed structure of the entire device, while the runway is the running channel for the scraper 4 and chain 5. The specific structure includes the following parts:

[0022] The support frame 1 is the foundational structure of the entire equipment. Located outside the equipment, it supports the entire runway and bears the weight of the equipment. A certain gap (hollowed-out portion) exists between the support frame 1 and the runway. This gap effectively reduces friction between the support frame 1 and the runway, while preventing vibration from being transmitted to the interior of the runway, thereby maintaining the stable operation of the scraper 4 and chain 5.

[0023] The runway is located inside the support frame 1 and is divided into an upper runway 2 and a lower runway 3. The scraper 4 is the part that contacts the material and slides along the upper runway 2 and the lower runway 3 to transport the material;

[0024] The scraper 4 is the component that comes into direct contact with the material during conveying, responsible for transporting it from its starting point to its destination. The scraper 4 is connected to the chain 5 and driven along the track by the chain 5. The scraper is made of high-strength, wear-resistant material to minimize friction with the track surface and extend its service life.

[0025] The chain 5 is driven by the power device to drive the scraper 4 to move along the runway. The main function of the chain 5 is to transmit power to the scraper and push the scraper to complete the material conveying process. The chain runs in the gap (hollow) area between the runway and the support frame 1. The gap is Figure 1 The area indicated by A in the middle reduces direct contact with the runway and avoids unnecessary wear.

[0026] A sprocket is mounted on the chain 5 , and the scraper is connected to the sprocket via a connecting rod or a connecting ring. The sprocket rotates when the chain 5 moves, thereby driving the scraper to move.

[0027] The three-dimensional scraper chain track also includes a cross brace 6, which is arranged below the upper runway 2 to ensure the structural stability of the entire runway system. During the operation of the scraper 4 and the chain 5, the cross brace 6 prevents the runway from deforming or sinking through its supporting function. In this embodiment, the cross braces 6 are evenly arranged along the length direction of the upper runway 2 and are perpendicular to the movement direction of the upper runway 2. The spacing between two adjacent cross braces 6 is 1200-1300 mm, ensuring that the runway can obtain uniform support throughout its entire length. Such a spacing design can effectively prevent the runway from deformation or vibration due to excessive span. Among them, the material of the cross brace 6 is high-strength steel or other wear-resistant and corrosion-resistant alloy materials, which can withstand the impact force generated by the chain 5 and the scraper 4 during operation.

[0028] The chain track of the scraper conveyor of this utility model is driven by a power device, and the chain drives the scraper to slide along the upper runway 2 to realize the conveying of materials. The following is a detailed description of its operation process:

[0029] When the equipment starts, the power device (such as a motor) transmits power to the chain 5 through the transmission mechanism. The chain 5 runs along the hollow part between the support frame 1 and the runway ( Figure 1 The scraper 4 is driven by the chain 5 and moves along the runway. A certain gap is maintained between the chain 5 and the runway to avoid direct contact, thereby reducing wear.

[0030] The scraper 4 slides along the runway through the movement of the chain 5 to complete the material conveying work. Because the scraper 4 can move evenly on the runway through the chain 5, and the motor guides the chain to move along the set path, the scraper 4 can effectively prevent the chain from deflecting due to uneven force or external forces, thereby avoiding chain drift or skew.

[0031] Horizontal braces 6, as the supporting structure for the upper runway 2, stabilize the runway and reduce deformation. The impact forces exerted on the runway by the scrapers 4 and chains 5 during operation are dispersed and absorbed by the horizontal braces 6, preventing excessive vibration. Furthermore, the horizontal braces 6 prevent the runway from sinking or deforming during extended use, extending the service life of the equipment.

[0032] The design of this utility model significantly improves the operational stability and durability of the scraper. Specific advantages include:

[0033] By separating the chain 5 from the runway, the chain 5 runs in the gap between the support frame and the runway, thus avoiding direct friction between the chain 5 and the runway and greatly reducing wear and tear on the equipment.

[0034] The cross braces 6 are evenly distributed along the length of the upper runway 2, effectively supporting the upper runway 2 and preventing the upper runway 2 from deforming or sinking during long-term operation. At the same time, the cross braces 6 can withstand vibrations and impacts generated during operation, ensuring that the scraper and chain 5 can operate smoothly.

[0035] Traditional scraper conveyors are prone to chain drift or scraper skew during operation, resulting in unstable material transportation. The utility model optimizes the connection structure between the chain and the runway to avoid direct contact between the chain and the runway. The chain runs more stably in the hollow part, reducing the occurrence of chain drift and skew.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
