Description

Technical Field

[0001] This utility model relates to the technical field of gantry scraper reclaimers, and specifically to an anti-blocking distributor for gantry scraper reclaimers. Background Technology

[0002] Since their application in industrial production in the mid-20th century, gantry cranes have undergone a transformation from mechanical drive to automated control. Initially designed primarily for handling single types of materials, scraper cranes have continuously evolved with the diversification of industrial needs. Modern gantry cranes can handle a variety of materials, including powders, granules, and lumps, and possess a certain degree of automation. However, the existing MQ250 / 53 gantry cranes inevitably experience coal accumulation near the travel track during the material handling process. This coal accumulation is difficult to automatically divert, leading to continuous and stable operation due to track congestion. The problem of track congestion remains a key factor limiting the crane's efficiency and stability.

[0003] Meanwhile, during the material handling process, problems such as material overflow and accumulation on the travel track causing blockages often occur, seriously affecting production efficiency and normal equipment operation. Traditional anti-blockage measures, including vibrator-assisted unloading, air cannon purging, and manual cleaning, all have certain limitations and shortcomings. Summary of the Invention

[0004] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide an anti-blocking distributor for a gantry scraper reclaimer, which can solve the problem that the existing equipment is unable to operate continuously and stably due to blockage of the travel track, effectively improving production efficiency and equipment stability, and making material handling safer.

[0005] To solve the aforementioned technical problems, this application adopts the following technical solution:

[0006] A gantry scraper reclaimer anti-blocking distributor includes a base plate installed on the outside of the cantilever bucket of the gantry scraper reclaimer, a plurality of fixed rods on one side of the base plate, and a pusher plate inclinedly installed on one side of the base plate via the fixed rods. The base plate is parallel to the outside of the cantilever bucket, and the lower end face of the pusher plate after installation maintains a gap of 0.5 to 1.5 cm with the ground.

[0007] Preferably, the pusher plate is set at a horizontal angle of 45° to the bottom plate, and the pusher plate is vertically inclined at 3° in the opposite direction to the scraper.

[0008] Preferably, one side of the pusher plate is provided with an elevation angle side plate, and the angle between the elevation angle side plate and the front of the pusher plate is 140-160°.

[0009] Preferably, the pusher plate has a forward-sloping top plate.

[0010] Preferably, the bottom plate has two first slide rails on one side, and a first slider is provided on the first slide rail. The first slider is welded to the outside of the cantilever bucket. The first slide rail and the first slider are provided with a plurality of first positioning holes. The first slide rail and the first slider are relatively fixed to each other through the first positioning holes.

[0011] Preferably, the pusher plate has two longitudinally arranged second slide rails on one side, and the end of the fixing rod has a second slider. The second slide rails and the second slider have a plurality of second positioning holes, and the second slide rails and the second slider are fixed relative to each other through the second positioning holes.

[0012] Preferably, both the first slide rail and the second slide rail adopt an H-shaped structure.

[0013] Preferably, a stop bar is provided at the lower end of the two first sliders, and the stop bar is welded to the outside of the cantilever bucket.

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

[0015] Compared to traditional anti-clogging technologies, the anti-clogging distributor for gantry scraper reclaimers effectively solves the problem of material blockage, improves production efficiency, and reduces energy consumption and maintenance costs. In terms of efficiency improvement, the anti-clogging distributor can respond promptly to blockage situations, reducing production downtime, preventing blockages caused by localized accumulation, and significantly improving unblocking efficiency.

[0016] The anti-clogging distributor avoids the problems associated with continuously operating high-energy-consuming equipment. It utilizes the kinetic energy of the gantry scraper reclaimer's trolley movement for operation, significantly reducing energy consumption and operating costs. In the current context of energy scarcity and increasingly stringent environmental requirements, the application of this non-powered technology is particularly important. Furthermore, it reduces physical impact and vibration, extending the equipment's lifespan and lowering maintenance costs.

[0017] By reducing manual intervention during operation and lowering the risk of workers being exposed to hazardous environments, the anti-blocking distributor of the gantry scraper reclaimer can automatically clear blockages without manual intervention, ensuring the health and safety of workers. It also extends equipment lifespan, reduces mechanical impact and wear, makes equipment operation smoother, reduces unexpected malfunctions, and improves equipment reliability.

[0023] like Figure 1 As shown, an anti-blocking distributor for a gantry scraper reclaimer includes a base plate 10 installed on the outside of the cantilever bucket of the gantry scraper reclaimer, a plurality of fixing rods 7 provided on one side of the base plate 10, and a pusher plate 1 inclinedly provided on one side of the base plate 10 through the fixing rods 7. The base plate 10 is arranged parallel to the outside of the cantilever bucket, and the lower end face of the pusher plate 1 after installation maintains a gap of 0.5 to 1.5 cm with the ground.

[0024] An anti-clogging distributor is installed on the outside of the cantilever bucket of the gantry scraper reclaimer. Its main material is national standard steel, ensuring structural durability and anti-sticking properties. The bottom plate 10 is fitted to the bottom of the cantilever bucket, without affecting the cyclic operation of the sprocket and scraper under the support of the cantilever. The bottom plate 10 is welded parallel to the cantilever bucket. The bottom plate 10 effectively prevents material from being pushed into the bottom of the cantilever bucket due to uneven ground, thus avoiding the risk of coal dust spontaneously combusting due to friction. It also reduces the load on the traveling system, decreases the frequency of failures, and increases the sustainable operation and service life of the equipment. The pusher plate 1 is inclinedly installed on one side of the track of the gantry scraper reclaimer via several fixed rods 7. Utilizing the physical displacement during the equipment's movement, it pushes overflowing material near the track back to the feeding line, thereby improving transportation efficiency and quality. Simultaneously, it protects the track, ensuring the continuous operation of the gantry scraper reclaimer and making its operation more efficient. The anti-clogging distributor consumes no power, significantly reducing energy consumption and operating costs, while also reducing equipment maintenance costs and complexity. Made of national standard steel with fire-retardant coating, it can adapt to different material characteristics, improving the reliability and stability of the equipment.

[0025] After installation, this device will not disrupt the original equipment's functionality. During the material handling process of the MQ250 / 53 gantry scraper reclaimer, the anti-blocking distributor works simultaneously, automatically diverting accumulated coal near the travel track to ensure unobstructed movement. This reduces the frequency of manual cleaning of congested coal on the travel track, alleviating worker fatigue. It effectively prevents coal clogging of the MQ250 / 53 gantry scraper reclaimer during operation, ensuring continuous, stable, and safe operation, improving production efficiency and equipment stability, and enhancing material handling safety.

[0026] A further improvement is that the pusher plate 1 is set at a horizontal angle of 45° to the base plate 10, and the pusher plate 1 is vertically inclined at 3° in the opposite direction to the scraper.

[0027] The rear end of the pusher plate 1 is connected and fixed to the cantilever bucket and base plate 10 via a fixing rod 7. After the pusher plate 1 is tilted horizontally at 45°, it can effectively guide and push the material during the movement of the equipment to the cantilever bucket feed line. This improves the efficiency and quality of material transportation and protects the travel track from foreign objects, ensuring the continuous operation of the reclaimer's travel system and reducing the frequency of failures. In particular, the pusher plate 1 is also tilted vertically at 3° in the opposite direction to the scraper. This structure is optimized based on the material flow characteristics and the mechanism of blockage. By guiding the material to flow smoothly through a specific tilt angle, the stagnation and accumulation of material in the reclaimer are reduced, thereby effectively preventing blockages.

[0028] A further improvement is made in that an elevation angle side plate 5 is provided on one side of the pusher plate 1, and the angle between the elevation angle side plate 5 and the front of the pusher plate 1 is 140-160°.

[0029] The added side plate 5 at an upward angle can push unblocked material back to the scraper opening and clean up coal accumulation inside the trolley's travel track, further enhancing the anti-blocking effect.

[0030] A further improvement is that the top of the pusher plate 1 is provided with a top plate 4 that is tilted forward.

[0031] Since the material pusher plate 1 will inevitably increase the accumulation height when clearing the material, in order to prevent the material from overflowing from the top to the back, a forward-sloping top plate 4 is added to the top of the material pusher plate 1. The combination of the top plate 4 and the tilting side plate 5 can make the material pusher plate 1 more stable and the clearing trajectory cleaner during the material clearing process.

[0032] A further improvement is made in that the bottom plate 10 has two first slide rails 8 on one side, and a first slider 9 on the first slide rail 8. The first slider 9 is welded to the outside of the cantilever bucket. The first slide rail 8 and the first slider 9 are provided with a plurality of first positioning holes 11. The first slide rail 8 and the first slider 9 are relatively fixed to each other through the first positioning holes 11.

[0033] The first slider 9 is welded to the outside of the cantilever bucket, and the first slide rail 8 is welded to the inside of the base plate 10. The first slide rail 8 and the fixing rod 7 together form a crisscrossing reinforcing rib structure on the base plate 10, improving the stability of the base plate 10 and the cantilever bucket. This allows the base plate 10 with the first slide rail 8 to be modularly assembled and disassembled with the cantilever bucket, and makes adjusting the relative position of the base plate 10 more convenient and flexible. After the base plate 10 is mounted on the first slider 9 on one side via two first slide rails 8 and its position is determined, the two can be positioned relative to each other by bolts passing through the first positioning holes 11.

[0034] A further improvement is made in that the pusher plate 1 has two longitudinally arranged second slide rails 3 on one side, the end of the fixing rod 7 has a second slider 2, the second slide rails 3 and the second slider 2 have a plurality of second positioning holes 6, and the second slide rails 3 and the second slider 2 are fixed relative to each other through the second positioning holes 6.

[0035] The second slider 2 is welded to one end of the fixing rod 7, and the second slide rail 3 is welded to the rear side of the pusher plate 1. The second slide rail 3 enables the rear end of the pusher plate 1 to form a reinforcing rib structure, thereby improving its rigidity during material pushing and making it less prone to deformation, while also reducing the thickness requirement of the pusher plate 1. When the pusher plate 1 needs to be replaced, disassembly is more convenient. At the same time, the height of the pusher plate 1 can be adjusted to a certain extent through the second positioning hole 6, thus solving the problem of inconvenient adjustment of the bottom height of the pusher plate 1 relative to the ground.

[0036] A further improvement is made in that both the first slide rail 8 and the second slide rail 3 adopt an H-shaped structure.

[0037] Both the first slide rail 8 and the second slide rail 3 adopt an H-shaped structure, which provides a larger operating space when installing the first slider 9 and the second slider 2.

[0038] A further improvement is made by providing a stop bar 12 at the lower end of the two first sliders 9, and the stop bar 12 is welded to the outside of the cantilever bucket.

[0039] A stop bar 12 is welded at a certain distance from the lower end of the first slider 9. When the base plate 10 is installed, the lower end of the first slide rail 8 can be stopped by contacting the stop bar 12 to prevent it from falling off when it is locked.

[0040] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
