Description

Technical Field

[0001] The invention relates to the technical field of steel plate processing, in particular to a steel plate equal-distance cutting machine and a cutting method thereof for producing a tray-type bridge. Background Art

[0002] Tray-type bridge is a cable support structure widely used in the fields of petroleum, chemical industry, electric power, etc. ‌Structural composition‌: It is mainly composed of upper tray, lower tray and connectors, and the material is usually high-strength steel with sufficient bearing capacity. ‌Design advantages‌: 1. ‌Modularity‌: It can be assembled into different shapes and sizes according to needs to meet various wiring needs. 2. ‌Protection‌: It provides good protection for the cable to prevent damage from the external environment and extend the service life. 3. ‌Heat dissipation‌: The bottom perforated design enhances the heat dissipation performance. ‌Application field‌: It is not only suitable for the laying of power cables and control cables, but also widely used in various bridge constructions, such as highway bridges, railway bridges, etc., to provide stable support. ‌Maintenance management‌: It is necessary to regularly check whether the connectors are tightened, corroded or damaged to ensure the stability of the overall structure‌.

[0003] With its unique structural design and excellent load-bearing capacity, the tray-type bridge provides an efficient and stable solution for cable management and bridge construction.

[0004] There are various ways to cut the steel plates for tray-type bridges. The following are some common cutting methods: 1. Manual cutting: Suitable for smaller metal bridges, use manual tools such as scissors or cutting knives for cutting, but the precision requirements are not high. 2. Mechanical cutting: Use shearing machines, wire saws and other mechanical equipment for cutting to improve cutting accuracy and efficiency. It is suitable for large metal bridges. 3. Grinding wheel cutting: Use high-speed rotating grinding wheels to cut steel. It is light and flexible and suitable for cutting small diameter pipes. 4. Flame cutting: Heat the metal until it melts through the chemical reaction of oxygen and hot steel. It is suitable for thicker metal bridges, but safety must be paid attention to. 5. Laser cutting: Use high-energy laser beams to heat, melt, and vaporize metals to achieve high-precision and high-speed cutting. It is suitable for occasions with extremely high cutting accuracy requirements. When cutting thicker metal bridges, flame cutting is usually used. Since flame cutting equipment will produce a strong chemical reaction during operation, which makes the surrounding temperature high, when using flame cutting equipment to cut the steel plate of the tray bridge, it is necessary not only to ensure the uniform size of the steel plate cutting, that is, to achieve equal spacing of the steel plate, but also to ensure the safety of the surrounding personnel and the service life of the machine tool, to avoid damage to the machine tool by the flame cutting equipment, and to reduce the risk of personnel being burned by the flame cutting equipment.

When the driving assembly is running, the conveying assembly and the reciprocating assembly will run alternately.

[0034] In this solution, the conveying assembly and the reciprocating assembly are operated alternately under the action of the driving assembly, and the steel plates are cut at equal intervals by the alternating operation of the conveying assembly and the reciprocating assembly; when the conveying assembly is in operation, the steel plates can be transported horizontally and stably to the bottom of the flame cutting gun 6, thereby improving the stability of the cutting process; when the reciprocating assembly follows the operation of the driving assembly through the speed increasing transmission structure, the reciprocating assembly will drive the rotating rod 4 to slide back and forth in the slide groove 3, and at the same time, the flame cutting gun 6 will move with the rotating rod 4 through the fixing frame 5, and when the rotating rod 4 is located in the horizontal groove 301 and slides When the rotating rod 4 moves to the inclined groove 302, the flame cutting gun 6 will slide horizontally to cut the steel plate, wherein the length of the horizontal groove 301 is greater than the width of the steel plate; when the rotating rod 4 slides from the horizontal groove 301 to the inclined groove 302, the flame cutting gun 6 will be lifted to stop cutting the steel plate while avoiding damage to the machine tool 1; in addition, when the rotating rod 4 moves to the inclined groove 302, the set deflection assembly will cause the rotating rod 4 to rotate at a certain angle, so that the flame cutting gun 6 deflects toward the center of the machine tool 1 with the rotating rod 4 as the rotation axis, thereby reducing the risk of personnel being burned by the flame cutting gun 6 and improving safety performance.

[0035] See also Figure 3 , Figure 7 , the reciprocating assembly includes a guide rod 7 horizontally arranged on the gantry 2 and a moving plate 8 slidably arranged on the guide rod 7; A sleeve 9 is vertically arranged on one side of the movable plate 8, a slide bar 10 is vertically slidably arranged at the bottom of the sleeve 9, and the bottom of the slide bar 10 is rotatably connected to one end of the rotating rod 4; A control box 17 is disposed on the top of the moving plate 8 , and the flame cutting gun 6 is electrically connected to the control box 17 .

[0036] In this embodiment, since the moving plate 8 is slidably disposed on the guide rod 7, and the moving plate 8 and the rotating rod 4 are connected by the sleeve 9 and the slide rod 10 that are slidably matched, when the moving plate 8 slides horizontally, the rotating rod 4 will move following the moving plate 8 through the sleeve 9 and the slide rod 10; Because the sleeve 9 and the slide bar 10 are in sliding cooperation, when the rotating rod 4 slides in the horizontal groove 301, the sleeve 9 and the slide bar 10 will be kept stationary; when the rotating rod 4 slides from the horizontal groove 301 to the inclined groove 302, the sleeve 9 and the slide bar 10 will slide against each other, and the rotating rod 4 will drive the flame cutting gun 6 to rise through the fixing frame 5; the control box 17 is used to provide power to the flame cutting gun 6.

[0038] In this embodiment, since the first sprocket 13 fixed on the first rotating shaft 11 and the second sprocket 14 fixed on the second rotating shaft 12 are connected by the chain 15, when the first rotating shaft 11 rotates, the first sprocket 13 will drive the second sprocket 14 and the second rotating shaft 12 to rotate synchronously through the chain 15; Furthermore, since a slide post 16 is rotatably provided on one of the links of the chain 15 and the slide post 16 is located inside the T-shaped groove 801 and slides with each other, the movable plate 8 will perform horizontal reciprocating movement during the rotation of the chain 15 .
