A flame cutting platform

Abstract

This invention provides a flame cutting platform, comprising a base consisting of multiple crossbeams and connecting beams. The base is connected to a welded positioning channel steel via a pad. Support rods pass through positioning holes in the positioning channel steel and sit on the crossbeams of the base. The bottom of the support rods is machined into a flat surface for contact with the crossbeams of the base, and the top of the support rods is machined into a frustum shape to support the steel plate to be cut. During operation, the steel plate to be cut is placed on top of the support rods, which lift the steel plate to a certain height, detaching it from the positioning channel steel. This prevents the flame from cutting through the flanges of the positioning channel steel during the cutting process. This allows the cutting platform to be used continuously. When individual support rods are damaged, only the damaged support rod needs to be pulled out of the positioning hole and replaced; other components do not need frequent replacement, thus reducing costs.

Description

Technical Field

[0001] This invention patent relates to the field of equipment manufacturing technology, and more specifically, to a flame cutting platform for steel structure fabrication and blanking. Background Technology

[0002] In steel structure fabrication, flame cutting of steel plates placed on a cutting platform is a common method. Traditional cutting platforms consist of a base and multiple evenly spaced strip steel plates on it, with the steel plate to be cut placed directly on these strips. During cutting, the high temperature of the flame can easily cut through the strips on the platform, or cause slurry backflow when the cutting line of the steel plate coincides with the strips, affecting the cutting quality. Statistics show that in actual construction, the combined economic cost of dealing with defects caused by the overlapping of the cutting line and the strips, as well as the regular replacement of the strips, amounts to approximately 10,000 yuan per month. This method is labor-intensive, costly, and cannot guarantee the quality of steel plate cutting or construction safety. Therefore, how to extend the service life of flame cutting platforms, facilitate maintenance, reduce operating costs, and effectively improve the cutting quality of steel plates is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a flame cutting platform that can extend the service life of the flame cutting platform, facilitate maintenance, reduce the cost of use, and effectively improve the cutting quality of steel plates.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is a flame cutting platform that changes the strip support to a point support, including a base and a pad plate set on the crossbeam of the base. The base is composed of multiple hot-rolled H-beam crossbeams and channel steel connecting beams. The pad plate avoids the positioning holes on the positioning channel steel and is welded to the base and the positioning channel steel. The positioning channel steel is welded to the crossbeam of the base to form an integral whole through the pad plate. The positioning channel steel has positioning holes drilled at equal intervals on the two flanges of the channel steel. The positioning holes drilled at equal intervals on the two flanges of the channel steel must be through to facilitate the insertion of the support rod. The bottom of the support rod is machined into a flat surface for contact with the top surface of the crossbeam of the base, and the top of the support rod is machined into a frustum shape to support the steel plate to be cut.

[0005] The present invention provides a flame cutting platform, including a base frame consisting of multiple crossbeams connected by a connecting beam, a positioning channel steel welded to the crossbeams of the base frame by a pad, and a support rod passing through a positioning hole on the positioning channel steel and sitting on the crossbeams of the base frame. The support rod is used to support the steel plate to be cut.

[0006] During operation, the steel plate to be cut is placed on the support rod, which lifts the steel plate to a certain height and detaches it from the positioning channel steel. This prevents the positioning channel steel from being cut during the cutting process, allowing the cutting platform to be used continuously. If an individual support rod is damaged, the damaged support rod can be pulled out of the positioning hole and replaced with that single support rod. Other parts do not need to be replaced frequently, thus reducing costs.

[0007] The advantages of this invention are: changing the support from strip to point not only saves steel but also greatly reduces the chance of the cutting line of the steel plate coinciding with the support point on the cutting platform, effectively improving the cutting quality of the steel plate. When the support rod is damaged, it can be quickly replaced, making maintenance convenient and efficient. Attached Figure Description

[0011] The following is combined with Figure 1 The present invention will be further described in detail below with reference to specific embodiments.

[0012] The present invention provides a flame cutting platform, including a base composed of multiple crossbeams 1 and connecting beams 2. The positioning channel steel (4) is welded to the crossbeam of the base to form an integral whole through the pad plate (3). The support rod 5 passes through the positioning hole on the positioning channel steel 4 and sits on the crossbeam of the base. The bottom of the support rod 5 is processed into a flat surface for contact with the top surface of the crossbeam of the base. The top of the support rod 5 is processed into a frustum shape for supporting the steel plate to be cut.

[0013] During operation, the steel plate to be cut is placed on top of the support rod 5. The support rod 5 lifts the steel plate to a certain height, detaching it from the positioning channel steel 4, thus preventing the flame from cutting through the flange of the positioning channel steel 4 during the cutting process. This allows the cutting platform to be used continuously. If an individual support rod is damaged, only the damaged support rod needs to be pulled out of the positioning hole and replaced; other parts do not need frequent replacement, thereby reducing costs.
