A new type of wear-resistant submerged roller

Abstract

This utility model discloses a novel wear-resistant submerged roller, belonging to the field of submerged roller technology. It includes: a roller body with multiple annular positioning grooves on its surface; multiple positioning holes arranged symmetrically in pairs on opposite side walls of the annular positioning grooves; and multiple semi-circular wear-resistant rings that are respectively inserted into the annular positioning grooves. This utility model extends the roller body by snapping the semi-circular wear-resistant rings together, forming a zinc-removing groove structure characteristic of submerged rollers. The semi-circular wear-resistant rings replace the coating of the submerged roller in contact with the workpiece, achieving the same effect. After prolonged use, only the wear-resistant rings need to be replaced to give the submerged roller a new wear-resistant structure, eliminating the need for complete disassembly and reassembly of the submerged roller. This makes the replacement of the submerged roller simple and convenient, avoids prolonged downtime, and saves time.

Description

Technical Field

[0001] This utility model belongs to the field of submerged roller technology, and in particular relates to a new type of wear-resistant submerged roller. Background Technology

[0002] Submerged rollers are important components in the zinc pot of the galvanizing unit. They are usually referred to as the "three major components" of the zinc pot, along with the straightening rollers and stabilizing rollers. In the continuous hot-dip galvanizing process, when the steel strip to be galvanized passes through the zinc pot containing molten zinc, it needs to change its direction of movement by submerged rollers immersed in the zinc liquid, while controlling the smooth running of the steel strip to ensure that the steel strip can be evenly coated with zinc in the zinc liquid.

[0003] Due to the harsh working environment, submerged rollers are considered consumable parts that must be replaced regularly. The replacement frequency is usually from a few days to two weeks, depending on the production process and product requirements. The main reason for replacing submerged rollers is because of the wear-resistant coating on the surface of the gyroscope.

[0004] Currently, the submerged rollers need to be completely disassembled and replaced, which not only makes the replacement operation inconvenient but also takes up a lot of downtime, resulting in wasted labor time. Utility Model Content

[0005] The purpose of this utility model is to propose a new type of wear-resistant submerged roller in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel wear-resistant submerged roller, comprising:

[0007] The roller body has multiple annular positioning grooves on its surface. Multiple positioning holes are symmetrically arranged in pairs on the opposite side walls of the annular positioning grooves. The multiple positioning holes on the same side are arranged in an annular array.

[0008] Multiple semi-circular wear-resistant rings are respectively inserted into multiple annular positioning grooves. Two semi-circular wear-resistant rings located in the same annular positioning groove are arranged symmetrically. A zinc discharge groove is formed between two adjacent semi-circular wear-resistant rings. The semi-circular wear-resistant rings are inserted into multiple positioning holes by multiple piston parts.

[0009] As a further description of the above technical solution:

[0010] The multiple annular positioning grooves are arranged at equal intervals along a straight line.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the semi-circular wear-resistant ring is provided with an annular protrusion, and a pressure chamber is opened in the annular protrusion. The pressure chamber is filled with hydraulic oil, and multiple piston grooves are opened in the inner wall of the pressure chamber. Multiple piston components are slidably connected in the multiple piston grooves.

[0013] As a further description of the above technical solution:

[0014] The piston groove has a limiting groove on its inner wall, and the piston head is provided at the end of the piston component. The piston head is slidably connected in the limiting groove.

[0015] As a further description of the above technical solution:

[0016] The side wall of the semi-circular wear-resistant ring is provided with a connecting channel for connecting to the pressure chamber, and a valve body is provided at the end of the connecting channel.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the semi-circular wear-resistant rings are snap-fitted onto the roller body, forming the zinc discharge groove structure of the submerged roller between the semi-circular wear-resistant rings. The semi-circular wear-resistant rings replace the coating of the submerged roller to contact the workpiece, achieving the same effect. After long-term use, only the wear-resistant rings need to be replaced to give the submerged roller a new wear-resistant structure. There is no need to disassemble the submerged roller as a whole, making the replacement of the submerged roller simple and convenient, avoiding long-term downtime and saving time.

[0019] 2. In this utility model, by injecting or extracting hydraulic oil into the pressure chamber, the piston slides in the piston groove under the action of hydraulic pressure, thereby allowing the piston to be inserted into or pulled out of the positioning hole, which facilitates the rapid expansion and installation of the semi-circular wear-resistant ring on the roller body, and also facilitates the rapid disassembly and replacement of the semi-circular wear-resistant ring.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a novel wear-resistant submerged roller, comprising:

[0029] Roller 1 has multiple annular positioning grooves 2 on its surface. Multiple positioning holes 3 are symmetrically arranged in pairs on the opposite side walls of the annular positioning grooves 2. The multiple positioning holes 3 on the same side are arranged in an annular array.

[0030] Multiple semi-circular wear-resistant rings 4 are respectively inserted into multiple annular positioning grooves 2. Two semi-circular wear-resistant rings 4 located in the same annular positioning groove 2 are arranged symmetrically. A zinc discharge groove 5 is formed between two adjacent semi-circular wear-resistant rings 4. The semi-circular wear-resistant rings 4 are inserted into multiple positioning holes 3 by multiple piston parts 6.

[0031] The plurality of annular positioning grooves 2 are arranged at equal intervals along a straight line;

[0032] The inner wall of the semicircular wear-resistant ring 4 is provided with an annular protrusion 7, and a pressure chamber 8 is opened in the annular protrusion 7. The pressure chamber 8 is filled with hydraulic oil, and the inner wall of the pressure chamber 8 is provided with multiple piston grooves 9. Multiple piston parts 6 are slidably connected in the multiple piston grooves 9. By injecting or extracting hydraulic oil into the pressure chamber 8, the piston parts 6 slide in the piston grooves 9 under the action of hydraulic pressure, thereby allowing the piston parts 6 to be inserted into or pulled out of the positioning hole 3. This facilitates the quick expansion and installation of the semicircular wear-resistant ring 4 on the roller body 1, and also facilitates the quick disassembly and replacement of the semicircular wear-resistant ring 4.

[0033] The inner wall of the piston groove 9 is provided with a limiting groove 10, and the end of the piston 6 is provided with a piston head 11. The piston head 11 is slidably connected in the limiting groove 10. The piston head 11 can only slide within a limited length range of the limiting groove 10, thereby limiting the stroke range of the piston 6 in the piston groove 9 and preventing the piston 6 from sliding out of the piston groove 9.

[0034] The side wall of the semi-circular wear-resistant ring 4 is provided with a connecting channel 12 for connecting the pressure chamber 8. A valve body 13 is provided at the end of the connecting channel 12 to facilitate the injection or extraction of hydraulic oil into the pressure chamber 8.

[0035] Working principle: First, during normal use, the semi-circular wear-resistant rings 4 form the zinc discharge groove 5 structure of the submerged roller. The semi-circular wear-resistant rings 4 replace the coating of the submerged roller to contact the workpiece, achieving the same effect as a conventional submerged roller. Second, after a period of use, hydraulic oil is simply drawn from the connecting channel 12 into the pressure chamber 8 through the valve body 13. Under the action of hydraulic pressure, the piston 6 slides in the piston groove 9, and the piston head 11 slides in the limiting groove 10, allowing the piston 6 to be pulled out from the corresponding positioning hole 3, releasing the restriction between the semi-circular wear-resistant rings 4 and the roller body 1. Finally, a new semi-circular wear-resistant ring 4 is inserted into the annular positioning groove 2, and hydraulic oil is injected into the pressure chamber 8 through the connecting channel 12 through the valve body 13. Under the action of hydraulic pressure, the piston 6 slides in the piston groove 9, and the piston head 11 slides in the limiting groove 10, allowing the piston 6 to be inserted into the corresponding positioning hole 3, completing the extended installation of the semi-circular wear-resistant rings 4 on the roller body 1.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
