Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, and in particular to a scraper for coal mine transportation equipment with a detachable wear-resistant liner. Background Technology

[0002] Lined coal mine transport equipment is mostly scraper conveyors with liners. The liners protect the equipment body from coal wear and are commonly used for coal transport in underground or surface coal mines. The scraper is the core component, which, together with the chain, can stably push the coal along the transport path. It can also help to sort out accumulated coal, ensuring continuous and efficient coal transport, avoiding blockages, and ensuring smooth transport operations.

[0003] However, during long-term use, the existing scrapers are prone to increased wear on the liner and scraper groove due to their sharp-angled ends. Furthermore, the flat scraper makes it easy for coal to spill out from both sides during transportation, and the scraper is easily damaged during transport. This requires extensive replacement and repair of the scraper, increasing maintenance costs and downtime, and the replacement and repair are also quite difficult.

[0004] Therefore, we provide a scraper with a detachable wear-resistant liner for coal mine transportation equipment to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a detachable wear-resistant liner scraper for coal mine transportation equipment, aiming to solve the aforementioned problems.

[0006] To achieve the above objectives, the system includes a scraper body, with material-gathering plates at the left and right ends of the front side of the scraper body, grooved drag-reducing ball frames on the left and right sides of the scraper body, a load-bearing keel on the rear side of the scraper body, a scraper mounting assembly installed in the middle of the scraper body, a scraper mounting groove in the middle of the scraper body, a front mounting plate installed on the front side of the scraper mounting groove, a rear mounting plate installed on the rear side of the scraper mounting groove, bolt frames welded to the outer sides of the front and rear mounting plates, a scraper connecting bolt passing through the middle of the bolt frame, and a connecting chain connected to the middle of the scraper connecting bolt.

[0007] Preferably, the material-gathering plate and the scraper plate are welded together, the material-gathering plates are arranged symmetrically in two groups on the left and right, and the material-gathering plates are inclined at an inward 15-degree angle.

[0008] Preferably, the grooved drag-reducing ball frame is welded to the scraper plate body, the grooved drag-reducing ball frame is arranged symmetrically in two groups on the left and right, and the grooved drag-reducing ball frame has a spherical structure.

[0009] Preferably, the front mounting plate and the rear mounting plate are connected to the scraper mounting groove in a front and rear side slotted manner. The front mounting plate and the rear mounting plate have through bolt holes. A mounting plate connecting bolt is installed inside the through bolt hole. The mounting plate connecting bolt is used to screw and fix the front mounting plate and the rear mounting plate through the through bolt hole.

[0010] Preferably, both the front mounting panel and the rear mounting panel are welded with a panel load-bearing side frame on their outer sides, and a side frame connecting bolt is connected in the middle of the panel load-bearing side frame. The side frame connecting bolt passes through the scraper plate body and is connected to the panel load-bearing side frame.

[0011] Preferably, a front mounting plate locking block is welded to the lower side of the front mounting plate, and a rear mounting plate locking groove is opened on the lower side of the rear mounting plate. The front mounting plate locking block and the rear mounting plate locking groove are connected by a locking groove. The front mounting plate locking block and the rear mounting plate locking groove cooperate to fasten and limit the front mounting plate and the rear mounting plate.

[0012] Preferably, the lower side of each of the bolt plate frames is provided with a plate-bearing reinforcing rib, and the plate-bearing reinforcing ribs are arranged in two groups, front and back, and the plate-bearing reinforcing ribs are connected by bolts.

[0013] This utility model provides a detachable wear-resistant liner scraper for coal mine transportation equipment. Compared with the prior art, it has the following advantages:

[0014] 1. This detachable wear-resistant liner scraper for coal mine transportation equipment, during use, uses a material-gathering plate to push the coal material forward. The material-gathering plate is tilted at a 15-degree angle, which can effectively gather the material towards the center, thereby preventing the material from scattering to both sides during transportation and improving conveying efficiency. In addition, conventional scraper plates have acute angles on both sides, which are prone to scraping against the inner wall of the conveying trough during operation, increasing resistance and aggravating wear. The grooved drag-reducing ball frame adopts a spherical structure, which can effectively reduce the contact area between the scraper and the trough wall during movement, reduce frictional resistance, and at the same time avoid jamming, improving smooth operation.

[0015] 2. This detachable wear-resistant liner scraper for coal mine transportation equipment involves aligning the front and rear mounting plates with the slots in the scraper mounting groove, inserting and adjusting them until they fit snugly. Then, the plate connecting bolts are passed through the plate through-bolt holes and tightened to fix the scraper body between the front and rear mounting plates. The bolt frame is connected to the connecting chain via the scraper connecting bolts, enabling the scraper body to move in traction. This allows for individual scraper body removal and replacement when needed, without disassembling the entire chain assembly. After installing the front and rear mounting plates, the side frame connecting bolts are passed through the scraper body and connected to the load-bearing side frame of the other plate, then locked. This strengthens the overall structural strength of the front and rear mounting plates, serving as a supplementary reinforcement to the plate through-bolt holes and effectively preventing loosening of the connection due to vibration or impact during high-load operation.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a detachable wear-resistant liner scraper for coal mine transportation equipment, including a scraper body 1, with material-gathering plates 2 at the left and right ends of the front side of the scraper body 1, grooved drag-reducing ball frames 3 on the left and right sides of the scraper body 1, a load-bearing keel 4 on the rear side of the scraper body 1, a scraper mounting assembly 5 installed in the middle of the scraper body 1, a scraper mounting groove 501 opened in the middle of the scraper body 1, a front mounting plate 502 installed on the front side of the scraper mounting groove 501, a rear mounting plate 506 installed on the rear side of the scraper mounting groove 501, a bolt frame 503 welded to the outer side of the front mounting plate 502 and the rear mounting plate 506, a scraper connecting bolt 504 passing through the middle of the bolt frame 503, and a connecting chain 505 connected to the middle of the scraper connecting bolt 504.

[0025] The material-gathering plate 2 and the scraper plate body 1 are welded together. The material-gathering plate 2 is arranged in two symmetrical groups on the left and right, and the material-gathering plate 2 is inclined inward at a 15-degree angle.

[0026] During use, the coal material is moved by the material gathering plate 2, which is tilted at a 15-degree angle, which can effectively gather the material towards the center, thereby preventing the material from scattering to both sides during transportation and improving the conveying efficiency.

[0027] The grooved drag-reducing ball frame 3 is welded to the scraper plate body 1. The grooved drag-reducing ball frame 3 is arranged in two symmetrical groups on the left and right sides, and the grooved drag-reducing ball frame 3 has a spherical structure.

[0028] During use, the conventional scraper body 1 has sharp angles on both sides. These sharp angles are prone to scraping against the inner wall of the conveying trough during operation, increasing resistance and aggravating wear. The grooved drag-reducing ball frame 3 adopts a spherical structure, which can effectively reduce the contact area between the scraper and the trough wall during movement, reduce frictional resistance, avoid jamming, and improve smooth operation.

[0029] The front mounting plate 502 and the rear mounting plate 506 are connected to the scraper mounting groove 501 by front and rear side slots. The front mounting plate 502 and the rear mounting plate 506 have through bolt holes 507. The inner side of the bolt hole 507 is fitted with a connecting bolt 508. The connecting bolt 508 is screwed to fix the front mounting plate 502 and the rear mounting plate 506 through the bolt hole 507.

[0030] In use, align the front mounting plate 502 and the rear mounting plate 506 with the slots of the scraper mounting groove 501, insert them and adjust them to fit. Then, pass the plate connecting bolt 508 through the plate through bolt hole 507 and tighten it to fix the scraper plate body 1 between the front mounting plate 502 and the rear mounting plate 506. The bolt bracket 503 is connected to the connecting chain 505 through the scraper connecting bolt 504 to realize the traction movement of the scraper plate body 1. Thus, when replacement is needed, the scraper plate body 1 can be disassembled and replaced separately without disassembling the entire chain assembly.

[0031] Both the front mounting plate 502 and the rear mounting plate 506 have a plate bearing side frame 509 welded to their outer sides. A side frame connecting bolt 510 is connected in the middle of the plate bearing side frame 509. The side frame connecting bolt 510 passes through the scraper plate body 1 and is connected to the plate bearing side frame 509.

[0032] After the front mounting plate 502 and the rear mounting plate 506 are installed, the side frame connecting bolts 510 are inserted through the scraper plate body 1 and connected to the other side of the plate bearing side frame 509 and locked, thereby strengthening the overall structural strength of the front mounting plate 502 and the rear mounting plate 506. As a supplementary reinforcement means for the plate through bolt holes 507, it effectively prevents the connection from loosening due to vibration or impact during high-load operation.

[0033] A front mounting plate latch 511 is welded to the lower side of the front mounting plate 502, and a rear mounting plate slot 512 is opened on the lower side of the rear mounting plate 506. The front mounting plate latch 511 and the rear mounting plate slot 512 are connected by a slot. The front mounting plate latch 511 and the rear mounting plate slot 512 cooperate to fasten and limit the front mounting plate 502 and the rear mounting plate 506.

[0034] When installing the front mounting plate 502 and the rear mounting plate 506, first install the rear mounting plate 506 onto the rear side of the scraper mounting groove 501, and then snap the front mounting plate 502 onto the front side of the scraper mounting groove 501 from bottom to top. At this time, the front mounting plate locking block 511 under the front mounting plate 502 is inserted into the rear mounting plate locking groove 512, so as to achieve precise alignment of the front and rear mounting plates and form a stable fastening, effectively limiting the relative displacement of the two in the lateral and vertical directions and improving the connection stability.

[0035] The lower side of the bolt plate frame 503 is provided with a plate stress-bearing reinforcing rib 513. The plate stress-bearing reinforcing rib 513 is arranged in two groups, front and back, and the plate stress-bearing reinforcing rib 513 is connected by bolts.

[0036] After the front mounting plate 502 and the rear mounting plate 506 are installed, the reinforcing ribs 513 are fixed to the outside of the front mounting plate 502 and the rear mounting plate 506 with bolts. This improves the bending and shear resistance of the front mounting plate 502 and the rear mounting plate 506. Especially during the long-term operation of the scraper conveyor, it effectively disperses stress concentration and prevents the front mounting plate 502 and the rear mounting plate 506 from deforming or cracking due to excessive local pressure.

[0037] Working principle: When needed, first place the scraper plate body 1 in the desired position, then fasten the front mounting plate 502 and the rear mounting plate 506 to the front and rear ends of the scraper mounting groove 501 in the middle of the scraper plate body 1, respectively. The front mounting plate locking block 511 and the rear mounting plate locking groove 512 on the lower side of the front mounting plate 502 and the rear mounting plate 506 are correspondingly engaged together. After installation, the mounting plate connecting bolt 508 passes through the mounting plate through bolt hole 507 to fix the front mounting plate 502 and the rear mounting plate 506 together. Then, use the side bracket connecting bolt 510 to connect the mounting plate force-bearing side bracket 509 outside the front mounting plate 502 and the rear mounting plate 506 together.

[0038] After preparation, install the connecting chain 505 into the middle of the bolt plate frame 503, then pass the scraper connecting bolt 504 through the connecting chain 505 and fix it into the middle of the bolt plate frame 503, connecting multiple sets of scraper plates 1 in series.

[0039] As the scraper body 1 is used, the grooved drag-reducing ball frames 3 at both ends of the scraper body 1 will be embedded into the grooves on both sides for limiting the movement. As the scraper body 1 moves, the material-gathering plate 2 on the surface will gather the coal material inward, thereby improving the material gathering effect. In addition, the stress-bearing keel 4 on the rear outer wall of the scraper body 1 improves the compressive strength of the scraper body 1. This completes the use of a detachable wear-resistant liner scraper for coal mine transportation equipment.

[0040] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
