Description

Technical Field

[0001] This utility model relates to the field of vibrating screen pipe beam protection technology, and in particular to a protection device for segmented modular vibrating screen pipe beams. Background Technology

[0002] Screening machines are widely used in industries such as mining, metallurgy, coal, chemical, power, and construction. During operation, the tube beams of the screening machine are subjected to the scouring effect of the material passing through the screen, which easily leads to corrosion and wear, reducing the strength and rigidity of the structure, shortening its service life, and consequently affecting the structural reliability of the vibrating screen itself. To reduce corrosion and wear, protective measures must be taken for the tube beams. Currently, there are three types of tube beam protection: welded steel plates, rubber lining, and polyurethane cladding. Among these, polyurethane cladding has advantages such as relatively low cost and reusability. However, it is known that polyurethane cladding cannot completely protect the weld seams of the crossbeams, and damage to one area cannot be repaired, requiring the replacement of the entire polyurethane cladding, significantly increasing the operating and maintenance costs of the vibrating screen. Utility Model Content

[0003] To overcome the technical deficiencies of existing technologies, this utility model provides a segmented modular protective device for the vibrating screen tube beam, with each segment installed and disassembled independently. When the polyurethane cladding plate is damaged after long-term use, only the damaged section needs to be replaced, eliminating the need to replace the entire beam, thus shortening maintenance time and reducing the operating and maintenance costs of the vibrating screen.

[0004] The technical solution adopted by this utility model is: a protective device for a segmented modular vibrating screen tube beam, including a protective sleeve wrapped around the tube beam with a circular cross-section, the protective sleeve extending from one end of the tube beam to the other end of the tube beam; the protective sleeve is formed by connecting multiple protective sub-sleeves at the ends of the circular tubes and protective sub-sleeves at the vertical plates. The protective sleeve at the round tube includes a first clamp body that hugs the outside of the tube beam. The first clamp body has a first mating plate that is mated with each other at its mating end. The first mating plate has a first positioning hole, and the first positioning holes are fixed together by a first fastening bolt. The protective sleeve at the upright plate includes a second clamp body that hugs the outside of the pipe beam. The docking end of the second clamp body is provided with a second docking plate that docks with each other. The second docking plate is provided with a second positioning hole, and the second positioning hole is fixed to each other by a second fastening bolt. The second clamp body is provided with a through groove for the upright plate to pass through. One end of the through groove is provided with a partition joint. The partition joint divides the second clamp body located on both sides of the upright plate into independently set clamping parts. Both ends of the protective sleeve at the round pipe and the protective sleeve at the upright plate are provided with docking mechanisms for docking with the adjacent protective sleeve at the round pipe or the protective sleeve at the upright plate.

[0005] Preferably, the protective sleeve at the round tube and the protective sleeve at the vertical plate are both injection molded from TDI or MDI material.

[0006] Preferably, the docking mechanism includes a third docking plate that is disposed at one end of the protective sleeve at the round tube and the protective sleeve at the upright plate and extends forward, and a pressure plate that extends forward is provided at the other end of the protective sleeve at the round tube and the protective sleeve at the upright plate, and a docking groove is formed between the pressure plate and the protective sleeve at the round tube and the protective sleeve at the upright plate for the third docking plate to be inserted.

[0007] Preferably, the openings of the first and second docking plates after docking face the next side and are away from the splashes.

[0008] Preferably, the width of the partition joint is 2 mm.

[0009] Preferably, the surfaces of the protective sleeve at the round tube and the protective sleeve at the upright plate are provided with a mesh-like anti-impact net, and the anti-impact net is an aramid woven mesh.

[0010] Preferably, multiple bases are embedded in the protective sleeves at the round tube and the vertical plate, and the bases are provided with threaded holes for bolts to pass through. The anti-collision mesh is fixed to the surface of the protective sleeves at the round tube and the vertical plate by bolts.

[0011] The beneficial effects of this utility model are: 1. This utility model divides the protective sleeve into multiple sections, each of which can be installed and disassembled independently. When the polyurethane cladding plate is damaged after long-term use, only the damaged section needs to be replaced, eliminating the need to replace the entire plate, thus shortening maintenance time and reducing the operating and maintenance costs of the vibrating screen. Furthermore, by setting protective sleeves at the round pipe and vertical plate locations, the round pipe sleeve protects the smooth, straight section of the pipe beam, while the vertical plate sleeve has a 2mm gap on one side of the second clamp, allowing the polyurethane cladding plate to be pulled open and passed through the vertical plate of the pipe beam for easy installation. Only one vertical plate installation opening is provided on the polyurethane cladding plate, ensuring a tight fit to the crossbeam and preventing direct contact between the crossbeam and materials, while also protecting the welds and extending the crossbeam's service life.

[0012] 2. The present invention provides a third connecting plate extending forward from one end of the protective sleeve at the round pipe and the protective sleeve at the vertical plate. The other end of the protective sleeve at the round pipe and the protective sleeve at the vertical plate is provided with a pressure plate extending forward. The pressure plate and the protective sleeve at the round pipe and the protective sleeve at the vertical plate form a connecting groove for the third connecting plate to be inserted. In this way, the adjacent protective sleeves at the round pipe and the protective sleeve at the vertical plate have a better connecting effect, and avoid the pipe beam being exposed due to the displacement of the protective sleeves at the round pipe and the protective sleeve at the vertical plate during daily use, thus failing to play a good protective role.

[0013] 3. The protective sleeves at both the round tube and the upright plate of this utility model are provided with a mesh-like anti-impact net. This anti-impact net is made of aramid fiber. This net protects the surfaces of the protective sleeves at the round tube and the upright plate from scratches by large flying objects, thus improving their service life. Furthermore, the anti-impact net is bolted to the surfaces of the protective sleeves at the round tube and the upright plate, facilitating disassembly and installation. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0018] like Figures 1 to 6 As shown, this embodiment 1 provides a protective device for a segmented modular vibrating screen tube beam, including a protective sleeve 2 that wraps around the tube beam 1 with a circular cross-section, extending from one end of the tube beam 1 to the other end; the protective sleeve 2 is formed by connecting multiple end-to-end protective sub-sleeves 3 at the circular tube and protective sub-sleeves 4 at the vertical plate; the protective sleeve 2 is divided into multiple segments, and each segment is installed and disassembled independently. When the polyurethane cladding plate is damaged after long-term use, only the damaged small segment needs to be replaced, without replacing the entire beam, shortening maintenance time and reducing the operation and maintenance cost of the vibrating screen; and by setting the protective sub-sleeves 3 at the circular tube and the protective sub-sleeves 4 at the vertical plate, the protective sub-sleeves 3 at the circular tube protect the smooth straight section of the tube beam 1.

[0019] The protective sleeve 3 at the circular tube includes a first clamp body 301 that hugs the outside of the tube beam 1. The first clamp body 301 has a first mating plate 302 that is mated with each other at its mating end. The first mating plate 302 has a first positioning hole 303, and the first positioning holes 303 are fixed together by a first fastening bolt 304. The clamp body is designed to facilitate installation and disassembly and has the characteristics of good positioning effect.

[0020] The protective sleeve 4 at the upright plate includes a second clamp body 401 that hugs the outside of the pipe beam 1. The mating end of the second clamp body 401 has a second mating plate 402 that abuts against each other, and the second mating plate 402 has a second positioning hole 403. The second positioning holes 403 are fixed together by a second fastening bolt 404. The second clamp body 401 has a through groove 405 for the upright plate to pass through, and one end of the through groove 405 has a partition 406. The partition 406 divides the second clamp bodies 401 located on both sides of the upright plate into independently set clamping parts 407. The protective sleeve 4 at the upright plate has a 2mm partition 406 on one side of the second clamp body, allowing the polyurethane coating to be pulled open during installation and pass through the upright plate of the pipe beam 1 for easy installation. Only one upright plate installation opening is opened on the polyurethane coating, which can tightly fit the crossbeam to prevent direct contact between the crossbeam and materials, while also protecting the weld and improving the service life of the crossbeam. The openings of the first docking plate 302 and the second docking plate after docking face the next side and are away from the splashing material.

[0021] The protective sleeve 3 at the round tube and the protective sleeve 4 at the vertical plate are both injection molded from TDI or MDI material. TDI or MDI material is low-cost and has the characteristics of being soft and elastic, thus providing good protection.

[0022] Both ends of the protective sleeve 3 at the circular pipe and the protective sleeve 4 at the vertical plate are provided with a docking mechanism for connecting with adjacent protective sleeves 3 at the circular pipe or 4 at the vertical plate. The docking mechanism includes a third docking plate 5 extending forward from one end of the protective sleeve 3 at the circular pipe or 4 at the vertical plate, and a pressure plate 6 extending forward from the other end of the protective sleeve 3 at the circular pipe or 4 at the vertical plate. A docking groove 7 is formed between the pressure plate 6 and the protective sleeve 3 at the circular pipe or 4 at the vertical plate for the third docking plate 5 to insert into. This provides a better docking effect between adjacent protective sleeves 3 at the circular pipe or 4 at the vertical plate, preventing the pipe beam 1 from being exposed due to misalignment of the protective sleeves 3 at the circular pipe or 4 at the vertical plate during daily use, thus ensuring adequate protection.

[0023] Both the protective sleeve 3 at the round tube and the protective sleeve 4 at the upright plate are provided with a mesh-like impact-resistant net 8, which is made of aramid fiber. Multiple bases 9 are embedded within the protective sleeve 3 at the round tube and the protective sleeve 4 at the upright plate, and each base 9 has threaded holes 10 for bolts 11 to pass through. The impact-resistant net 8 is fixed to the surface of the protective sleeve 3 at the round tube and the protective sleeve 4 at the upright plate by bolts. This use of the impact-resistant net 8 to protect the surface of the protective sleeve 3 at the round tube and the protective sleeve 4 at the upright plate prevents them from being scratched by large flying objects, thereby improving their service life. Furthermore, the bolts 11 securing the impact-resistant net 8 to the surface of the protective sleeve 3 at the round tube and the protective sleeve 4 at the upright plate facilitate disassembly and installation.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Tooling principle: The protective sleeve 2 is divided into multiple sections, each of which can be installed and disassembled independently. When the polyurethane cladding plate is damaged after long-term use, only the damaged section needs to be replaced, without replacing the entire piece, shortening maintenance time and reducing the operating and maintenance costs of the vibrating screen. Furthermore, by setting up protective sleeves 3 at the round pipe and 4 at the vertical plate, the protective sleeve 3 at the round pipe protects the smooth, straight section of the pipe beam 1. A third connecting plate 5 extends forward from one end of each of the protective sleeves 3 and 4, while a pressure plate 6 extends forward from the other end. The pressure plate 6 and the protective sleeves 3 and 4 form a connecting groove 7 for the third connecting plate 5 to be inserted. This ensures a good connection between adjacent protective sleeves 3 and 4 at the round pipe and vertical plate, preventing the pipe beam 1 from being exposed due to misalignment of the protective sleeves 3 and 4 during daily use, thus achieving adequate protection.

[0026] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
