Description

Technical Field

[0001] This utility model relates to a scraper anti-detachment device, and particularly to a scraper anti-detachment device for scraper conveyors, belonging to the technical field of scraper conveyors. Background Technology

[0002] Scraper conveyors are conveying equipment that uses a circulating chain as the traction component and chain plates as the load-bearing component. They can transport bulk materials in a trough in a horizontal or inclined direction. The function of scraper conveyors is to transport materials, so they have become an indispensable main equipment in modern transportation processes.

[0003] In practical applications, scraper detachment often occurs due to long-term wear of the scraper chain and scraper, improper installation, or inadequate maintenance. This can not only lead to interruption of material conveying but also cause equipment failure and safety accidents. To prevent the scraper from detaching during the operation of the scraper conveyor, the scraper design often incorporates multiple bolt fastening mechanisms to ensure a stable connection.

[0004] However, under long-term dynamic loads, these bolts will inevitably loosen, causing the scraper to fall off. This requires operators to tighten the bolts regularly. This process not only increases the frequency and labor intensity of maintenance, but also makes the subsequent scraper maintenance process relatively cumbersome. Utility Model Content

[0005] The purpose of this utility model is to provide a scraper anti-detachment device for scraper conveyors, so as to solve the problems mentioned in the background art, such as poor anti-detachment effect, the need for operators to tighten bolts regularly, which increases the frequency of maintenance and labor intensity, and makes the subsequent maintenance process of scrapers complicated.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scraper conveyor scraper anti-detachment device, comprising a chain plate, a scraper body slidably disposed in the middle of both sides of the chain plate via a locking block, two fixing boxes symmetrically disposed in the middle of the chain plate, two insert strips slidably disposed inside the fixing boxes, a slot for inserting and engaging with the insert strips is provided on one side of the locking block, an inclined block one is disposed between the two insert strips, an inclined block two is slidably disposed on one side of the inclined block one via a limiting slide bar, a moving plate is disposed on one side of the inclined block two, a tensioning component is disposed on one side of the moving plate, a limiting block is engaged on the other side of the moving plate, and a limiting component is disposed on one side of the limiting block.

[0007] As a preferred embodiment of this utility model, a rectangular groove is provided in the middle of the top of the scraper body to engage with the chain plate, and a slot is provided on the top of the scraper body to engage with the locking block.

[0008] As a preferred technical solution of this utility model, a spring telescopic rod is provided in the middle of the other side of the inclined block, and one end of the spring telescopic rod is fixedly connected to the inner wall of one side of the fixed box.

[0009] As a preferred technical solution of this utility model, the first inclined block and the second inclined block are slidably connected, and the middle part of the second inclined block is provided with a limiting groove that slides and cooperates with the limiting slide bar.

[0010] As a preferred embodiment of this utility model, the tensioning assembly includes two guide rods, which are symmetrically installed on one side of the movable plate. A spring is provided between the movable plate and the fixed box, and the spring is sleeved on the outside of the guide rods.

[0011] As a preferred embodiment of this utility model, one end of each of the two guide rods passes through the fixing box and is provided with a pull rod, and the surface of the pull rod is covered with an anti-slip sleeve.

[0012] As a preferred technical solution of this utility model, the limiting component includes a guide strip, which is fixedly installed in the middle of the other side of the limiting block. Two grooves are opened on the other side of the moving plate to engage with the limiting block. A second spring is provided between the limiting block and the fixed box, and the second spring is sleeved on the outside of the guide strip.

[0013] As a preferred technical solution of this utility model, one end of the guide strip passes through the fixing box and is provided with a second pull rod, and the surface of the second pull rod is provided with a second anti-slip sleeve.

[0014] Compared with related technologies, the scraper anti-fall-off device for scraper conveyors provided by this utility model has the following beneficial effects:

[0015] 1. By interlocking the insert strip with the slot at the card block, the spring in the tensioning assembly can limit the second inclined block, thereby limiting the insert strip. On the other hand, the limiting block and the limiting assembly work together to limit the moving plate, preventing the second inclined block from loosening, thus limiting the insert strip a second time. This achieves double-layer locking of the insert strip, effectively preventing the scraper body from loosening during use, significantly improving the scraper body's anti-falling performance, and ensuring the stable operation of the equipment.

[0016] 2. By moving the movable plate, the second inclined block can be moved inside the fixed box. With the help of the limiting slide, the first inclined block can be moved inside the fixed box, which causes the insert to retract into the fixed box. At this time, the insert separates from the slot at the card block, making it easier to disassemble and remove the scraper body at the chain plate. This facilitates subsequent maintenance of the scraper body, reduces the frequency and labor intensity of maintenance, and makes the subsequent scraper maintenance process more convenient.

[0024] 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.

[0025] Please see Figure 1-6This utility model provides a scraper anti-detachment device for a scraper conveyor, including a chain plate 1. A scraper body 3 is slidably mounted on the middle of both sides of the chain plate 1 via a locking block 2. The scraper body 3, through the movement of the chain and the chain plate 1, can scrape and convey materials. Two fixed boxes 4 are symmetrically arranged in the middle of the chain plate 1. Two insert strips 5 are slidably mounted inside the fixed boxes 4. A blocking block is also provided inside the fixed boxes 4 to limit the movement of the insert strips 5, preventing the second inclined block 8 from sliding out of the first inclined block 6. A slot for insertion and engagement of the insert strip 5 is provided on one side of the locking block 2. An inclined block is provided between the two insert strips 5. One side of the inclined block 6 is provided with an inclined block 8 via a limiting slide 7. The movement of the inclined block 8, in conjunction with the limiting slide 7, enables the movement of the inclined block 6. One side of the inclined block 8 is provided with a moving plate 9, and one side of the moving plate 9 is provided with a stretching component 11. Through the stretching component 11, the moving plate 9 and the inclined block 8 can be moved inside the fixed box 4. The other side of the moving plate 9 is provided with a limiting block 12, which helps to limit the movement of the moving plate 9. Furthermore, one side of the limiting block 12 is provided with a limiting component 13, which helps to stretch the limiting block 12 so that the limiting block 12 can be inserted and limited at different positions of the groove 15.

[0026] The tensioning assembly 11 includes two guide rods 1101, which are symmetrically installed on one side of the movable plate 9. A spring 1102 is provided between the movable plate 9 and the fixed box 4, and the spring 1102 is sleeved on the outside of the guide rods 1101. The spring 1102 can cooperate with the movable plate 9 and the inclined block 8 to maintain support in the horizontal direction, and can support the inclined block 8.

[0027] One end of each of the two guide rods 1101 passes through the fixed box 4 and is provided with a pull rod 1103. The surface of the pull rod 1103 is covered with an anti-slip sleeve, which makes it easy for the operator to use the pull rod 1103 to stretch and move the guide rod 1101, the moving plate 9 and the inclined block 8, while also playing an anti-slip role.

[0028] The limiting component 13 includes a guide bar 1301, which is fixedly installed in the middle of the other side of the limiting block 12. Two grooves 15 are provided on the other side of the moving plate 9 to engage with the limiting block 12. A second spring 1302 is provided between the limiting block 12 and the fixed box 4, and the second spring 1302 is sleeved on the outside of the guide bar 1301 to support the limiting block 12, thereby limiting the moving plate 9.

[0029] One end of the guide bar 1301 passes through the fixed box 4 and is provided with a pull rod 1303. The surface of the pull rod 1303 is provided with an anti-slip sleeve 2, which facilitates the horizontal movement of the guide bar 1301 by the pull rod 1303.

[0030] The inclined block 6 and the inclined block 8 are slidably connected. The middle part of the inclined block 8 is provided with a limiting groove 10 that slides with the limiting slide bar 7, so that the inclined block 6 and the inclined block 8 can slide together, and the inclined block 6 can move under the action of the inclined block 8.

[0031] A spring telescopic rod 14 is provided in the middle of the other side of the inclined block 6. One end of the spring telescopic rod 14 is fixedly connected to the inner wall of the fixed box 4. The spring telescopic rod 14 is composed of a shaft, a bushing and a supporting spring inside it, which can limit and guide the movement of the inclined block 6.

[0032] A rectangular groove 17 is provided at the middle of the top of the scraper body 3 to engage with the chain plate 1, and a slot 16 is provided at the top of the scraper body 3 to engage with the locking block 2, so as to facilitate the engagement and connection between the scraper body 3 and the chain plate 1, and to facilitate the disassembly and assembly of the scraper body 3.

[0033] In use, firstly, multiple scraper bodies 3 are placed on the chain plate 1 of the chain for installation, facilitating material conveying. Next, the pull rod 2 1303 is stretched to move the guide bar 1301 horizontally, causing the limit block 12 to separate from the groove 15 on the moving plate 9. Then, the pull rod 1 1103 is stretched, causing it to stretch the guide rod 1101 and the moving plate 9. At this time, springs 1 1102 and 2 1302 are simultaneously compressed. During this process, the moving plate 9 is stretched and moved horizontally. The second inclined block 8 moves synchronously, cooperating with the limiting slide 7 and the limiting groove 10, so that the first inclined block 6 and the two inserts 5 move synchronously. When the inserts 5 abut against the blocking block inside the fixed box 4, they can limit the movement of the second inclined block 8. At the same time, the limiting block 12 and the other groove 15 of the moving plate 9 are on the same horizontal plane. At this time, the second pull rod 1303 is released. Under the support and rebound of the second spring 1302, the limiting block 12 and the groove 15 are inserted into each other, so as to limit the moving plate 9, the first inclined block 6 and the inserts 5. At this time, the inserts 5 are located inside the fixed box 4.

[0034] Next, the scraper body 3 is engaged with the slot 16 and rectangular groove 17 to lock the scraper body 3 and the chain plate 1. Then, the pull rod 1303 is stretched again to separate the limiting block 12 from the groove 15. Under the return of the spring 1102, the moving plate 9 and the inclined block 8 are reset. With the help of the spring telescopic rod 14 and the limiting slide 7, the two inserts 5 are reset and interlocked with the slots. This allows the scraper body 3 to be assembled and fixed with the chain plate 1. The spring 1102 can limit the inclined block 8, thereby limiting the insert 5. On the other hand, the limiting block 12 and the spring 1302 limit the moving plate 9 to prevent the inclined block 8 from loosening, thus limiting the insert 5 a second time. This achieves double-layer locking of the insert 5, which can effectively prevent the scraper body 3 from loosening during use and facilitate the use of the scraper conveyor.

[0035] 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.
