Description

Technical Field

[0001] This utility model relates to the field of screen technology, and in particular to a polyurethane bar screen hook assembly with strong connection. Background Technology

[0002] Polyurethane bar screens are widely used in various material screening equipment due to their wear resistance, impact resistance, and high screening efficiency. As the core connecting component of polyurethane bar screens, the reliability of the connection directly determines the overall performance and service life of the screen.

[0003] In the prior art, when polyurethane bar screens are connected to hooks, the polyurethane bars are fixed by only one method (such as bolt tightening or wire rope binding). They are prone to displacement or falling off due to material impact and screening vibration, requiring frequent maintenance. This results in high screen maintenance costs, short service life, and increased risk of material leakage and clogging during screening, which seriously affects screening efficiency.

[0004] Therefore, there is an urgent need for a polyurethane bar screen hook assembly with strong connection and excellent resistance to loosening. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a polyurethane bar screen hook assembly with strong connection, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a polyurethane bar screen hook assembly with strong connection, comprising multiple hook assemblies, wherein multiple polyurethane bars are connected together among the multiple hook assemblies;

[0007] The hook assembly includes a hanging plate and a hook bent into an arc shape at one end of the hanging plate. Multiple sets of lower positioning holes are equally spaced on one side of the surface of the hanging plate, and multiple sets of anchoring through holes are equally spaced on the other side of the surface of the hanging plate.

[0008] The hook assembly also includes a fixing plate, and the surface of the fixing plate has multiple sets of upper positioning holes corresponding to multiple sets of lower positioning holes.

[0009] As a further technical solution of this utility model, each set of lower positioning holes and upper positioning holes is provided with three, the fixing plate is connected to the hanging plate by bolts passing through the upper positioning holes and lower positioning holes, and one end of the polyurethane rod is located between the three lower positioning holes and is fixed to the hanging plate by the fixing plate.

[0010] As a further technical solution of this utility model, multiple polyurethane rods are fixed between multiple hook assemblies in a crisscross manner, and steel wire ropes are provided inside the polyurethane rods, with the steel wire ropes extending from both ends of the polyurethane rods respectively.

[0011] As a further technical solution of this utility model, each group of anchoring holes is provided with two holes. The steel wire ropes extending from both ends of the polyurethane rod are inserted into one anchoring hole and then exited through the other anchoring hole. The steel wire ropes are anchored in the anchoring holes by rivets.

[0012] As a further technical solution of this utility model, the bottom surface of the hanging plate is provided with an enlarged hole corresponding to each set of lower positioning holes, and the inner diameter of the enlarged hole is larger than the end cap of the bolt.

[0013] As a further technical solution of this utility model, the hanging plate and the hook are an integrated structure, and both the hanging plate and the fixing plate are made of metal.

[0014] This utility model provides a polyurethane bar screen hook assembly with strong connection, which has the following advantages compared with the prior art:

[0015] 1. This design provides a polyurethane bar screen hook assembly with strong connection. The polyurethane bars are fixed by a double fixing method of clamping with a fixed pressure plate and anchoring with steel wire rope rivets, which avoids loosening or falling off caused by material impact and vibration. This improves the connection between the bars and the hook assembly. Moreover, the integrated metal structure of the hanging plate and hook has no weak welding points, strong impact resistance and fracture resistance, and extends the service life of the hook assembly.

[0016] 2. This design features a robust polyurethane bar screen hook assembly. The fixing plate and the hanging plate are detachably connected by bolts. If the polyurethane bars are damaged, they can be disassembled and replaced individually without replacing the entire screen, reducing maintenance costs. Furthermore, the longitudinal and transverse spacing of the polyurethane bars can be adjusted according to screening requirements to adapt to screening scenarios with different particle sizes, making it highly versatile. In addition, the enlarged hole design on the bottom of the hanging plate can accommodate bolt end caps, ensuring a tight fit between the hook assembly and the screening equipment, reducing vibration gaps, and further reducing the risk of loosening.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 This utility model provides a technical solution for a polyurethane rod screen hook assembly with strong connection: a polyurethane rod screen hook assembly with strong connection includes multiple hook assemblies, and multiple polyurethane rods 4 are connected together among the multiple hook assemblies. The multiple polyurethane rods 4 are fixed between the multiple hook assemblies in a crisscross manner. Steel wire ropes 41 are provided inside the polyurethane rods 4. The steel wire ropes 41 extend from both ends of the polyurethane rods 4. The polyurethane rods 4 are made of high elastic polyurethane material, and the steel wire ropes 41 are made of galvanized steel wire rope, with each end extending 50-100mm for anchoring.

[0027] On the other side of the surface of the hanging plate 1, multiple sets of anchoring holes 12 are equally spaced. Each set of anchoring holes 12 has two holes. The steel wire rope 41 extending from both ends of the polyurethane rod 4 is inserted into one of the anchoring holes 12 and then exits through the other anchoring hole 12. The steel wire rope 41 is anchored in the anchoring hole 12 by rivets. The rivets are stainless steel blind rivets.

[0028] The hook assembly includes a hanging plate 1 and a hook 2 bent into an arc shape at one end of the hanging plate 1. The hanging plate 1 and hook 2 are an integral structure, and both the hanging plate 1 and the fixing plate 3 are made of metal, using 304 stainless steel. The thickness of the hanging plate 1 is 3-5mm, and the thickness of the fixing plate 3 is 2-3mm. They are integrally bent by a CNC bending machine. The radius of the arc hook 2 is 10mm to ensure compatibility with the hanging rod of the screening equipment. Multiple sets of lower positioning holes 11 are evenly spaced on one side of the surface of the hanging plate 1. The hook assembly also includes a fixing plate 3. Multiple sets of upper positioning holes 31 are provided on the surface of the fixing plate 3 corresponding to the multiple sets of lower positioning holes 11. Each set of lower positioning holes 11 and upper positioning holes 31 has three holes. The spacing between the three lower positioning holes 11 in the group is 5-8mm, and the spacing between groups is 50mm. It can be adjusted according to the spacing requirements of the polyurethane rods 4. The hole diameter, number and spacing of the upper positioning holes 31 and the lower positioning holes 11 are completely consistent to ensure that the bolts can pass through smoothly. The fixing plate 3 is connected to the hanging plate 1 by bolts passing through the upper positioning holes 31 and the lower positioning holes 11. The bolts are M6 stainless steel hexagonal bolts, with matching nuts and washers. One end of the polyurethane rod 4 is located between the three lower positioning holes 11 and is fixed to the hanging plate 1 by the fixing plate 3. The bottom surface of the hanging plate 1 has an enlarged hole corresponding to each group of lower positioning holes 11, and the inner diameter of the enlarged hole is larger than the end cap of the bolt to ensure that the end cap of the bolt is completely embedded in the enlarged hole.

[0029] The working principle of this utility model is as follows: the steel wire rope 41 extending from one end of the polyurethane rod 4 is passed through a set of anchoring holes 12 on one side of the hanging plate 1 (entering from the first anchoring hole 12 and exiting from the second anchoring hole 12), the position of the polyurethane rod 4 is adjusted so that the end face of the polyurethane rod 4 is in contact with the hanging plate 1; then the stainless steel blind rivets are driven into the anchoring holes 12 with a rivet gun to fix the steel wire rope 41 on the hanging plate 1, thus completing the second fixation;

[0030] Take the fixing plate 3 and align the upper positioning hole 31 on it with the lower positioning hole 11 on the other side of the hanging plate 1 to ensure that the end of the polyurethane rod 4 is located in the area between the three lower positioning holes 11 in the same group; pass the M6 ​​bolt through the upper positioning hole 31 and the lower positioning hole 11 in sequence, put on the washer, and tighten the nut so that the fixing plate 3 presses the end of the polyurethane rod 4 tightly on the hanging plate 1, completing the first layer of fixing;

[0031] Further, repeat steps 1-2 to connect the two ends of multiple polyurethane rods 4 to multiple hook components respectively, and the polyurethane rods 4 are arranged in a crisscross pattern (the longitudinal rods and the transverse rods intersect perpendicularly, and the intersections are fixed by polyurethane adhesive), finally forming a complete polyurethane rod screen.

[0032] The assembled screen is hung on the hanging rod of the screening equipment via the arc hook 2 of the hook assembly. Check whether the bottom surface of the hanging plate 1 is in contact with the surface of the equipment (the bolt end cap is embedded in the enlarged hole and there is no protrusion). After ensuring that the installation is firm, it can be put into use.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
