Description

Technical Field

[0001] The utility model relates to the field of steel gratings, in particular to a clamping device for processing steel gratings. Background Art

[0002] Steel grating, also known as mesh grille, is a steel product made by crisscrossing flat steel bars (twisted square steel, square steel, round steel, flat steel, etc.) at regular intervals and welded together to create a square grid. Steel grating is primarily used for gutter covers, steel structure platforms, and ladder treads. Crossbars are typically twisted square steel. Steel grating is typically made of carbon steel with a hot-dip galvanized exterior to prevent oxidation. Stainless steel can also be used. Steel grating offers ventilation, lighting, heat dissipation, anti-slip properties, and explosion-proof properties. Suitable for alloys, building materials, power plants, boilers, shipbuilding, petrochemicals, chemicals, general industrial plants, and municipal construction, it offers advantages such as ventilation, light transmission, anti-slip properties, strong load-bearing capacity, aesthetics, durability, ease of cleaning, and simple installation.

[0003] The existing clamping device for processing steel gratings has certain limitations when used. Due to the variety of sizes of steel gratings, the existing clamping device for processing steel gratings cannot be applied to a variety of steel gratings and has poor flexibility. Therefore, a clamping device for processing steel gratings is proposed to address the above problems. Utility Model Content

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1-5 As shown, a clamping device for processing steel grating includes:

[0031] Base 1;

[0032] Two vertical plates 2 are symmetrically fixed on both sides of the top of the base 1;

[0033] A rotating plate 4 is rotatably mounted on the inner side of the top of the vertical plate 2 via a rotating shaft;

[0034] A clamping assembly 6, which is arranged on the side of the rotating plate 4 and is used to clamp the steel grating;

[0035] The telescopic assembly 5 is provided between the rotating plate 4 and the clamping assembly 6. The clamping assembly 6 is mounted on the rotating plate 4 through the telescopic assembly 5, and the telescopic assembly 5 can drive the clamping assembly 6 to move horizontally and linearly;

[0036] During operation, the steel grating is placed between the clamping components 6 on both sides, and the edge positions of the steel grating on both sides are clamped and fixed by the clamping components 6 so as to process the steel grating. In addition, the telescopic components 5 can drive the clamping components 6 on both sides to move closer or farther in the horizontal direction, and then the distance between the clamping components 6 on both sides can be changed as needed to clamp and fix steel gratings of different sizes, which has a wider range of applications.

[0037] The clamping assembly 6 includes a mounting plate 61, a bottom plate 65 is fixedly connected to the bottom of the side of the mounting plate 61 away from the rotating plate 4, a movable plate 66 is movably installed above the bottom plate 65, a fixed plate 68 is fixedly installed in the middle of the top of the mounting plate 61, a spring 67 is fixedly installed between the fixed plate 68 and the movable plate 66, a hydraulic cylinder 2 62 is provided on the side of the mounting plate 61 close to the rotating plate 4, a connecting plate 63 is fixedly installed on the top of the telescopic end of the hydraulic cylinder, and a pull rope 64 is fixedly connected to the lower end surface of the end of the connecting plate 63, the bottom end of the pull rope 64 passes through the through hole provided in the middle of the fixed plate 68 and is fixedly connected to the movable plate 66; when working, the hydraulic cylinder 1 52 is started, The telescopic end of the hydraulic cylinder 52 extends upward, thereby driving the connecting plate 63 to move upward. The connecting plate 63 pulls the movable plate 66 upward synchronously through the pull rope 64. At this time, the spring 67 is compressed, and the distance between the movable plate 66 and the bottom plate 65 becomes larger, so that the steel grating can be placed above the bottom plates 65 on both sides. Then the telescopic end of the hydraulic cylinder 52 contracts, and under the rebound action of the spring 67, the movable plate 66 is pushed downward and pressed against the top of the steel grating so that the steel grating can be quickly clamped and fixed. The operation is simple and the clamping efficiency is improved. Moreover, the distance between the movable plate 66 and the bottom plate 65 can be changed according to demand, so that it is suitable for clamping steel gratings of different thicknesses, with wider applicability.

[0038] The telescopic assembly 5 includes a support shell 51, which is set to be U-shaped. A hydraulic cylinder 52 is fixedly installed at one end of the support shell 51 near the rotating plate 4 in the middle, and a moving shell 53 is movably installed at the side of the support shell 51 away from the rotating plate 4 in the middle. The telescopic end of the hydraulic cylinder 52 is fixedly connected to the side of the moving shell 53, and the mounting plate 61 is detachably installed on the side of the moving shell 53. The hydraulic cylinder 2 62 is fixedly installed in the moving shell 53. Sliders 54 are fixedly connected to both sides of the moving shell 53, and a slide groove 55 is provided on the side wall of the support shell 51. The slide 54 is slidably set in the slide groove 55. During operation, by controlling the extension or contraction of the telescopic end of the hydraulic cylinder 52, the moving shell 53 can be driven to move left and right, so that the spacing between the clamping assemblies 6 on both sides can be changed as needed to clamp and fix steel gratings of different sizes. In addition, by arranging the slide 54 and the slide groove 55, the movement direction of the moving shell 53 is limited, so that the moving shell 53 can only move back and forth linearly along the inside of the support shell 51.

[0039] The opposite sides of the bottom plate 65 and the movable plate 66 are fixedly mounted with rubber pads, which increase the friction between the bottom plate 65, the movable plate 66 and the steel grating during operation, making the clamping more secure.

[0040] Anti-slip blocks 610 are fixedly installed on both sides of the side walls of the movable plate 66 and the mounting plate 61, and a second slide groove 69 adapted to the anti-slip block 610 is provided on the mounting plate 61, and the anti-slip block 610 is slidably set in the second slide groove 69; when working, the anti-slip block 610 is set to a T shape, and the movable plate 66 is always fitted with the mounting plate 61 through the anti-slip block 610, and can move stably along the direction of the second slide groove 69.

[0041] A motor 3 is fixedly installed on the outer wall of the vertical plate 2 on one side to drive the rotating plate 4 on one side to rotate; when working, the rotating plate 4 on one side and the structure connected with it are driven to rotate by the motor 3, so as to drive the middle steel grating to rotate a certain angle, which is convenient for processing different positions of the steel grating.

[0042] One end of the connecting plate 63 extends to just above the fixing plate 68, and the pull rope 64 vertically passes through the through hole; during operation, the friction between the pull rope 64 and the inner wall of the through hole is reduced, thereby reducing the wear of the pull rope 64 and improving the service life of the pull rope 64.

[0043] Example 2

[0044] See also Figure 4 and Figure 5 As shown, compared with Example 1, as another embodiment of the present invention, a pair of plug rods 611 are fixedly connected to the side of the mounting plate 61, and a slot 612 is provided at the end of the movable shell 53 corresponding to the plug rod 611, and the plug rod 611 and the slot 612 are plugged into each other; when working, the plug rod 611 and the slot 612 cooperate to quickly disassemble and assemble the clamping assembly 6, which facilitates the maintenance and replacement of the symmetrical clamping assembly 6.
