Description

Technical Field

[0001] This application belongs to the field of quick-change positioning technology, specifically a shallow groove quick-change positioning device. Background Technology

[0002] Traditional shallow trench replacement technology suffers from problems such as long processing time, low efficiency, and disruption to production schedules. With the continuous advancement of intelligent and automated technologies, how to apply these technologies to the shallow trench replacement process to achieve fast, stable, and safe replacement has become an important direction for technological upgrading in the current coal industry.

[0003] In the current shallow trough system, the scraper and chain are connected by a connecting plate and are directly used to transport large pieces of gangue after sorting in the shallow trough. These are wear parts with a service life of approximately 3 months. Replacing the shallow trough scraper requires destructive dismantling of the chain, cutting it into seven to eight sections. Then, a crane is used to remove the cut chain and scraper from inside the shallow trough. The removal of the old scraper takes more than 3 hours. After the old scraper is removed, a new chain is installed in the shallow trough, and then the scraper is installed using the connecting plate, completing the entire scraper replacement process. However, the entire scraper replacement process takes approximately 8-10 hours, requires 8 maintenance workers, and involves installing over 200 screws. The labor intensity is high, and the process is time-consuming.

[0004] However, the common design of scraper structure components makes it inconvenient for workers to perform quick replacement operations. In the current technology, the scraper structure is fixedly connected, which is inefficient during replacement and not conducive to subsequent operations. Utility Model Content

[0005] The purpose of this application is to provide a shallow groove quick-change positioning device in order to solve the problem of the aforementioned structural component for quick-change positioning of scraper.

[0006] The technical solution adopted in this application is as follows: a shallow groove quick-change positioning device includes a working chain, a plurality of slot plates 2 are provided on the side of the working chain, a first slot is provided on the side of the slot plate 2, a first connecting plate 1 is slidably connected inside the first slot, a scraper is fixedly provided between adjacent first connecting plates 1, a plurality of fixing screws 2 are threadedly connected to the side of the slot plate 2, and the other end of the fixing screw 2 passes through the slot plate 2 and is inserted into a first fixing hole provided on the side of the first connecting plate 1.

[0007] By adopting the above technical solution, during the operation of the structural components, the installation of the first clamping plate and the scraper is facilitated by using the second clamping plate and the first clamping slot inside the second clamping plate. This allows for easy installation and removal of the first clamping plate and the scraper, reducing damage to the operating chain assembly, extending the equipment's service life, and lowering the company's equipment replacement costs. In use, the operator clamps the first clamping plate into the inside of the second clamping plate, inserts the second fixing screw into the side of the second clamping plate, and then connects to the first fixing hole on the side of the first clamping plate to secure the clamping plate, ensuring a stable connection of the structural components. When the scraper needs to be replaced after a period of operation, the operator removes the second fixing screw from the side of the second clamping plate, making it easy to remove the first clamping plate from inside the second clamping plate for scraper replacement. This facilitates subsequent operation and maintenance.

[0008] In a preferred embodiment, a plurality of slot plates are fixedly connected to the side of the working chain, and a second slot is provided on the side of each slot plate.

[0010] In a preferred embodiment, the working chain is provided with a plurality of rotating shaft assemblies, the second slot is slidably connected to the inside of the second slot, and the side of the second slot plate is fixedly connected to the second slot plate.

[0011] By adopting the above technical solution, the rotating shaft assembly drives the rotation of the working chain, and the second snap-fit ​​plate facilitates the connection of the second snap-fit ​​plate, thereby enabling the structural components to be connected to each other and facilitating subsequent operation.

[0012] In a preferred embodiment, the side of the slot plate is threaded with a plurality of fixing screws, and the other end of the fixing screws passes through the slot plate and is inserted into a second fixing hole provided on the side of the snap plate.

[0013] By adopting the above technical solution, the fixing screw fixes the clip plate, making the connection between the structural components stable and facilitating disassembly and installation.

[0014] In a preferred embodiment, the scraper is composed of a multi-layered composite material, and the interior of the scraper is provided with a stainless steel layer.

[0015] By adopting the above technical solution, the stainless steel layer has excellent corrosion resistance and strong high temperature resistance, making it suitable for highly corrosive environments and with a long service life.

[0016] In a preferred embodiment, an alloy steel layer is disposed inside the scraper at the lower end of the stainless steel layer.

[0017] By adopting the above technical solution, the alloy steel layer has high hardness and wear resistance. The wear resistance of the alloy steel layer is stronger than that of carbon steel, which facilitates subsequent operation.

[0018] In a preferred embodiment, a wear-resistant cast iron layer is provided inside the scraper at the lower end of the alloy steel layer.

[0019] By adopting the above technical solution, the wear-resistant cast iron layer contains a large amount of carbon, has extremely high wear resistance and good impact resistance, is suitable for high wear environments, and has good corrosion resistance.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, during the operation of the structural components, the installation of the first clamping plate and the scraper is facilitated by using the second clamping plate and the first clamping slot within the second clamping plate. This allows for easy installation and removal of the first clamping plate and the scraper, reducing damage to the operating chain assembly, extending the equipment's lifespan, and lowering equipment replacement costs. In use, the operator clamps the first clamping plate into the inside of the second clamping plate, inserts the second fixing screw into the side of the second clamping plate, and then connects to the first fixing hole on the side of the first clamping plate to secure it, ensuring a stable connection of the structural components. When the scraper needs to be replaced after a period of operation, the operator removes the second fixing screw from the side of the second clamping plate, allowing the first clamping plate to be easily removed from the inside of the second clamping plate, facilitating scraper replacement. This streamlined process enhances the operator's subsequent control and operation. Attached Figure Description

A scraper 6 is fixedly installed between adjacent first engaging plates 5. Multiple fixing screws 9 are threadedly connected to the side of each slotted plate 4. The other end of each fixing screw 9 passes through the slotted plate 4 and is inserted into a first fixing hole on the side of the first engaging plate 5. During the operation of the structural component, the installation of the first engaging plate 5 and the scraper 6 is facilitated by using the slotted plates 4 and the first slots within them. The installation and disassembly of the first engaging plate 5 and the scraper 6 are performed by facilitating the installation and disassembly of the first engaging plate 5 and the scraper 6, thereby reducing stress on the working chain 1 component. This prevents damage and extends the service life of the equipment, reducing the company's equipment replacement costs. During use, the operator snaps the first clip plate 5 into the inside of the second clip plate 4, then inserts the second fixing screw 9 into the side of the second clip plate 4, and then connects to the first fixing hole on the side of the first clip plate 5 to fix the first clip plate 5, ensuring a stable connection of the structural components. When the scraper 6 needs to be replaced after a period of operation, the operator removes the second fixing screw 9 from the side of the second clip plate 4, and then easily removes the first clip plate 5 from the inside of the second clip plate 4, facilitating the replacement of the scraper 6. This makes it convenient for the operator to replace the scraper 6 and facilitates subsequent operation.

[0030] Reference Figure 1-3 The side of the working chain 1 is fixedly connected with multiple slot plates 3. The side of the slot plate 3 is provided with a second slot. The slot plate 3 and the second slot cooperate with each other to realize the installation and disassembly of the snap plate 8, which is convenient for the operator.

[0031] Reference Figure 1-3The working chain 1 has multiple rotating shaft assemblies 2 inside. The second slot has a sliding connection of a second snap plate 8 inside. The side of the snap plate 8 is fixedly connected to a second slot plate 4. The rotating shaft assembly 2 drives the working chain 1 to rotate for operation. The snap plate 8 is designed to facilitate connection with the second slot plate 4, thereby connecting the structural components to each other and facilitating subsequent operation.

[0032] Reference Figure 1-3 The side of the slot plate 3 is threaded with multiple fixing screws 7. The other end of the fixing screws 7 passes through the slot plate 3 and is inserted into the second fixing hole on the side of the snap plate 8. The fixing screws 7 fix the snap plate 8, making the connection between the structural components stable and facilitating disassembly and installation.

[0033] Reference Figure 4 The scraper 6 is composed of multiple layers of composite materials. The interior of the scraper 6 is provided with a stainless steel layer 10. The stainless steel layer 10 has excellent corrosion resistance and strong high temperature resistance, making it suitable for highly corrosive environments and with a long service life.

[0034] Reference Figure 4 Inside the scraper 6, at the lower end of the stainless steel layer 10, there is an alloy steel layer 11. The alloy steel layer 11 has high hardness and wear resistance. The wear resistance of the alloy steel layer 11 is stronger than that of carbon steel, which facilitates subsequent operation.

[0035] Reference Figure 4 Inside the scraper 6, at the lower end of the alloy steel layer 11, there is a wear-resistant cast iron layer 12. The wear-resistant cast iron layer 12 contains a lot of carbon, has extremely high wear resistance and good impact resistance, is suitable for high wear environments, and has good corrosion resistance.

[0036] The implementation principle of an embodiment of a shallow groove quick-change positioning device in this application is as follows:

[0037] In the operation of the structural components, the use of the second slot plate 4 and the first slot opened inside the second slot plate 4 facilitates the installation of the first slot plate 5 and the scraper 6. The installation and disassembly of the first slot plate 5 and the scraper 6 reduces damage to the working chain 1 assembly, thereby extending the equipment's service life and lowering the company's equipment replacement costs. During use, the operator snaps the first slot plate 5 into the inside of the second slot plate 4, then inserts the second fixing screw 9 into the side of the second slot plate 4, and then connects to the first fixing hole on the side of the first slot plate 5 to fix the first slot plate 5 in place, ensuring a stable connection of the structural components. When scraper 6 needs to be replaced after a period of operation, the worker removes the fixing screw 29 from the side of the slot plate 24, and then easily removes the snap-fit ​​plate 15 from inside the slot plate 24, making it convenient to replace scraper 6. This facilitates the worker's replacement of scraper 6 and subsequent operation. By using a quick replacement device and optimizing the replacement process, a non-destructive connection between scraper 6 and the working chain 1 is achieved, improving replacement efficiency, reducing labor intensity, extending equipment life, and enhancing production safety. This creates greater economic benefits for the enterprise and promotes the sustainable and healthy development of the coal industry.
