Description

Technical Field

[0001] The utility model belongs to the technical field of engineering steel, and particularly relates to an assembled engineering steel drilling clamping device. Background Art

[0002] Engineering steel is the steel used to manufacture engineering structures that bear loads, also known as building structural steel. The main requirements for the performance of this type of steel are sufficient strength to ensure no permanent deformation and damage during use.

[0003] The engineering steel for manufacturing load-bearing structures, also known as building structural steel. The main requirements for the performance of this type of steel are sufficient strength to ensure no permanent deformation and damage during use. In addition, this type of steel often needs to be cut, bent, riveted, and welded during use, so good formability and weldability are also required. The carbon content of this type of steel is generally less than 0.30%, and most of it is rolled into section steels (such as angle steel, channel steel, I-beam, deformed steel bar, etc.), steel plates, and steel pipes with a certain cross-sectional shape for use. It is commonly used in engineering structures such as ships, vehicles, containers, and hoisting and transportation machinery, and is used to manufacture bridges, steel columns, steel beams, trusses, etc. in construction projects.

[0004] However, when drilling engineering steel, a clamping device needs to be installed on the outer wall of the engineering steel to fix the engineering steel to prevent displacement during the drilling process. However, after the clamping device contacts the engineering steel, when the drilling position needs to be adjusted, the clamping device still needs to be loosened, resulting in the inability of the clamping device to move along when changing the drilling position.

[0026] Refer to Figures 1 - 3 , a shown assembled engineering steel drilling clamping device, including a clamping plate 1. An engineering steel body 15 is arranged in the middle inside the clamping plate 1. Brake plates 9 are arranged on both sides of the inner wall of the clamping plate 1. An installation groove 10 is opened in the middle of the brake plate 9. Sliding grooves 11 are opened on both sides of the inner wall of the installation groove 10. A sliding block 12 is slidably connected inside the sliding groove 11. A moving roller 13 is rotatably connected between the two sliding blocks 12. A return spring 14 is arranged between the sliding block 12 and the sliding groove 11.

[0027] Furthermore, in the above technical solution, a groove is formed on one side of the clamping plate 1. On both sides of the top and bottom of the inner wall of the clamping plate 1, there are attached strips 2. The outer wall of the attached strip 2 is attached to the outer wall of the engineering steel body 15. The groove is aligned with the surface of the engineering steel body 15 to be drilled, which is convenient for drilling the surface of the engineering steel body 15 in the later stage. And the attached strip 2 is used to assist in fixing the engineering steel body 15 to prevent the engineering steel body 15 from deviating when the clamping plate 1 moves on the outer wall of the engineering steel body 15.

[0028] Furthermore, in the above technical solution, an installation block 4 is arranged on one side of the clamping plate 1. A transmission lead screw 5 is rotatably connected inside the installation block 4. The thread directions at both ends of the transmission lead screw 5 are opposite. A mating hole 7 is formed on one side of the lifting plate 6. The mating hole 7 cooperates with the transmission lead screw 5. Manually rotate the transmission lead screw 5 to drive the lifting plate 6 to lift or lower, so that the lifting plate 6 drives the brake plate 9 to separate from or attach to the outer wall of the engineering steel body 15.

[0029] Furthermore, in the above technical solution, sliding holes 3 are formed at the top and bottom of the clamping plate 1. A support rod 8 is slidably connected inside the sliding hole 3. The support rods 8 are symmetrically distributed on both sides of the horizontal center line of the clamping plate 1. One end of the support rod 8 is connected to the brake plate 9, and the other end of the support rod 8 is provided with a lifting plate 6.

[0030] The working principle of this utility model:

[0031] Refer to the attached drawings of the specification Figures 1 - 3 , first, when it is necessary to drill the outer wall of the engineering steel body 15, install the clamping plate 1 on the outer wall of the engineering steel body 15, and the attached strip 2 inside the clamping plate 1 is attached to the outer wall of the engineering steel body 15. Then move the roller 13 to be attached to the outer wall of the engineering steel body 15, and the clamping plate 1 can be pushed to move on the outer wall of the engineering steel body 15 through the moving roller 13 for adjusting the position of the clamping plate 1. After the adjustment is completed, manually rotate the transmission lead screw 5. The transmission lead screw 5 drives the lifting plate 6 to move towards the clamping plate 1. The lifting plate 6 drives the brake plate 9 to be attached to the outer wall of the engineering steel body 15 through the support rod 8. And the moving roller 13 is squeezed by the engineering steel body 15, so that the moving roller 13 drives the sliding block 12 to slide outwards on the inner wall of the sliding groove 11 and squeeze the return spring 14, so that the moving roller 13 is received into the installation groove 10, realizing the fixation of the clamping device to the outer wall of the engineering steel body 15, which is convenient for the later drilling device to drill the engineering steel body 15 through the groove on one side of the clamping plate 1.
