Description

Technical Field

[0001] The invention relates to the technical field of metallurgical equipment, and in particular to a guardrail of a sintering machine trolley, a sintering machine trolley and a tooling. Background Art

[0002] The sintering machine trolley is one of the main equipment of the sintering system, which is composed of a car body, grates, heat insulation parts, guardrails, etc. Among them, the guardrails of the sintering machine trolley are generally ductile iron ingots, which are formed by mechanical processing. The guardrails of the sintering machine trolleys used in existing sintering plants have serious thermal deformation problems, which often cause the guardrails of the sintering machine trolleys to break and become unusable, or fall outward and have to be shut down for maintenance or replacement, which in turn affects normal sintering production. Therefore, it is necessary to improve the existing sintering machine trolley guardrails to reduce the deformation of the guardrails. At the same time, the guardrail structure has three assembly surfaces that need to be milled. The conventional processing of the guardrails generally uses inclined shims for positioning, which requires reciprocating correction. Only one guardrail can be corrected and processed at a time, and the processing efficiency is extremely low, and the shape and position tolerances between the surfaces are unstable. Summary of the invention

[0003] The present invention proposes a guardrail for a sintering machine trolley to solve the problem of severe thermal deformation of the guardrail in the prior art, which often causes the guardrail of the sintering machine trolley to break and become unusable, or to fall outward and require the machine to be shut down for inspection or replacement, thereby affecting normal sintering production. By improving the structure of the guardrail, the strength of the guardrail is improved and the deformation of the guardrail is reduced.

[0004] The present invention also proposes a sintering machine trolley to solve the problem of severe thermal deformation of the guardrail in the prior art, which often causes the guardrail of the sintering machine trolley to break and become unusable, or to fall outward and require the machine to be shut down for inspection or replacement, thereby affecting normal sintering production. By improving the structure of the guardrail, the strength of the guardrail is improved and the deformation of the guardrail is reduced.

[0005] The present invention further proposes a tool for processing the guardrail of a sintering machine trolley, which is used to solve the problem in the prior art that the guardrail structure has three assembly surfaces that need to be milled. Conventional processing of the guardrail generally uses inclined washers for positioning, which requires reciprocating correction. Only one guardrail can be corrected at a time, and the processing efficiency is extremely low. In addition, the quality of the form and position tolerances between the surfaces is unstable. By improving the tooling and fixtures used in the processing of the guardrail, the guardrail can be processed and formed after one positioning, and batch clamping and rapid correction are realized, making full use of the processing capacity of the machine tool, and solving the problems of low processing efficiency and unstable quality of conventional methods.

[0006] According to a first aspect of the present invention, a guardrail of a sintering machine trolley is provided, comprising: a first assembly surface, a second assembly surface, a first blank surface, a second blank surface and reinforcing ribs;

[0009] The plurality of reinforcing ribs are arranged at intervals in a region surrounded by the first assembly surface, the second assembly surface, the first blank surface and the second blank surface, and are respectively connected to the second assembly surface, the first blank surface and the second blank surface;

[0010] Wherein, the first assembly surface and the second assembly surface are processing surfaces.

[0011] According to an embodiment of the present invention, the two first assembly surfaces are arranged in parallel and perpendicular to the first blank surface.

[0012] Specifically, this embodiment provides an implementation method of the first assembly surface. By arranging the two first assembly surfaces in parallel and perpendicular to the first blank surface, the convenience of installation between two adjacent railings is ensured, the versatility of the railings is improved, and the setting perpendicular to the first blank surface also enhances the strength of the railing.

[0013] According to an embodiment of the present invention, the second assembly surface is arranged parallel to the second blank surface and forms an angle with the first blank surface.

[0014] Specifically, this embodiment provides an implementation method of the second assembly surface, by setting the second assembly surface parallel to the second blank surface, so that the second blank surface has the same horizontal height after two adjacent railings are installed, thereby improving the versatility of the railings. At the same time, the setting of the second assembly surface perpendicular to the first blank surface also enhances the strength of the railings.

[0015] A sintering machine trolley provided according to a second aspect of the present invention comprises the guardrail of the sintering machine trolley described above.

[0016] According to a third aspect of the present invention, a tool for processing the above-mentioned sintering machine trolley guardrail includes: a base, a first limiting portion and a second limiting portion;

[0031] Specifically, this embodiment provides another implementation of the first limiting portion, by providing a first screw corresponding to the screw hole on the first limiting plate, so that the first screw can be used to position the railing in the vertical direction to avoid the movement of the railing during the processing. At the same time, the mating surface with the first screw is the second blank surface, and the second blank surface is a non-processing surface, so that the railing can be clamped once and then directly processed into shape.

[0040] Furthermore, by providing a third fiberboard abutting against the first blank surface, the position of the railing is more stable under the limiting action of the second limiting portion, thereby avoiding shaking during the processing.

[0041] Furthermore, by providing a second screw between the second support plate and the third limiting plate, the relative position between the third limiting plate and the first limiting portion can be adjusted by the second screw, thereby realizing the clamping of the railings of different sizes or when the thickness of the railings on the first blank surface is different due to process differences.

[0042] According to an embodiment of the present invention, the first limiting portion and the second limiting portion constitute a limiting assembly, and a plurality of the limiting assemblies are arranged at intervals on the base.
