Description

Technical Field

[0001] The invention relates to the technical field of section steel cutting, and in particular to a device for accurately cutting and unloading section steel for a steel structure platform. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates.

[0003] During the construction process, the steel sections need to be cut to length. Existing cutting methods include laser cutting, flame cutting, punching and the like. The present invention adopts laser cutting, which has a smooth cutting surface and a small cutting gap, and can fully utilize the steel sections. However, most existing cutting equipment sends the steel sections to the cutting tool for cutting. However, the steel sections themselves are heavy, and there are slippage and other phenomena during the transportation of the steel sections, resulting in poor cutting accuracy. In addition, the cutting equipment does not have the ability to mark, and there is a risk of errors in the lifting and installation of the steel sections. Summary of the invention

The second hydraulic cylinder is actuated to move the baffle in the length direction of the cutting platform, and the baffle resists the steel section to limit the steel section, while the first hydraulic cylinder is actuated, and its output end cooperates with the bottom of the baffle, at which time the baffle is in a vertical state, and when it is out of coordination, the baffle is flipped under the action of an external force, and at this time the cut steel section is delivered.

[0013] Preferably, counterweight bars are provided on both sides of the lower end of the baffle plate. The baffle plate can be quickly returned to a vertical state only under the action of the counterweight bars.

[0031] Combination Figure 1 and Figure 6 As shown, the cutting platform 2 includes two cross beams 25, and a plurality of supporting legs are fixedly connected to the lower ends of the cross beams 25. A conveying roller 23 is arranged between the two cross beams 25. The conveying roller 23 is used to convey the steel section. The driving structure of the conveying roller 23 is not shown here, or a driving motor is added inside the conveying roller 23 to drive the conveying roller 23 to rotate. A plurality of pairs of fixed baffles 22 and movable baffles 26 for clamping the steel section are also arranged between the two cross beams 25. After determining the cutting position of the steel section, the movable baffle 26 moves toward the fixed baffle 22 and clamps the steel section.

[0032] Combination Figure 3 and Figure 4 As shown, the mobile platform 3 includes an arch beam 33 of an arc structure, the end of the arch beam 33 is slidably matched with the cross beam 25, and a sliding groove or guide rail is provided between the two. A cutting mechanism 32 is slidably provided on the arch beam 33, and the cutting mechanism 32 includes a slider 327, and a cutter head 321 and a laser marker 323 are provided on the slider 327. Here, the cutter head 321 emits laser for cutting the steel, and the laser marker 323 is used for marking.

[0033] The lower end of the slider 327 is fixedly connected to the fourth hydraulic cylinder 324, and the output end of the fourth hydraulic cylinder 324 is fixedly connected to the fixed plate 322. The cutter head 321 and the laser marker 323 are both fixed on the fixed plate 322.

[0035] A laser generator 35 is disposed at one end of the arch beam 33 for generating laser light, and then the laser light is emitted from the end of the cutter head 321 through an optical fiber.

The middle part of the lower end of the U-shaped frame 14 is fixedly connected to the first hydraulic cylinder 11, and the output end of the first hydraulic cylinder 11 extends through and extends into the preset opening at the lower end of the baffle 13. When the first hydraulic cylinder 11 is actuated, its output end is inserted into the lower part of the baffle 13, that is, the rotation of the baffle 13 is limited to keep it vertical.

When the third hydraulic cylinder 24 is started, the movable blocking rod 26 moves to achieve clamping or releasing of the steel section. Embodiment 2

[0040] This embodiment is based on the first embodiment and proposes an automatic material unloading method, the specific contents of which are as follows:

[0041] Step 1: Each driving component of the unloading device is controlled by a host computer, and a position sensor or a distance sensor is added on this basis. When in use, the model of the tower steel structure to be built is input into the host computer, and the tower steel structure construction process is planned for each workpiece;

[0042] Step 2: Place the steel to be cut on the cutting platform 2, then input the model of the steel to be cut into the host computer, measure the length of the steel by the position sensor or distance sensor, and plan the cutting size according to the construction process. Further, input all the steel structures to be cut into the host computer, combine all the structures, and intelligently plan the cutting plan. The computer program automatically calculates here, so it will not be repeated;

[0043] Step 3: Adjust the position of the steel section placed on the cutting platform 2. At this time, the first hydraulic cylinder 11 and the second hydraulic cylinder 15 in the limiting mechanism 1 at one end cooperate with the conveying roller 23 to control the position of the steel section. Then, the third hydraulic cylinder 24 is actuated, and the movable stop rod 26 cooperates with the fixed stop rod 22 to clamp the steel section.

[0044] Step 4: At this time, under the linkage of the first motor 31, the second motor 326 and the fourth hydraulic cylinder 324, the cutter head 321 moves to the planned cutting position, and then performs laser cutting. At the same time, during the cutting process, the laser marking machine 323 also works to mark the cut workpiece to ensure that it is used incorrectly during lifting and installation;

[0045] Step 5: After the cutting is completed, the third hydraulic cylinder 24 is activated again, the movable blocking rod 26 releases the workpiece, and at the same time the first hydraulic cylinder 11 is activated to retract the output end. At this time, the baffle 13 has no restriction, and then the conveying roller 23 works to send the workpiece out of the cutting platform 2.

[0046] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
