DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0031] Example 1, please refer to Figure 1-Figure 4 The present invention provides a technical solution: a steel grating shearing mechanism is described as follows.

[0032] The operating platform 1 comprises: an operating table 1, a collecting bucket 2 is fixedly connected to the bottom of the operating table 1, a lifting column 3 is symmetrically arranged on the top of the operating table 1, a mounting frame 4 is fixedly connected to the top of the lifting column 3, and the mounting frame 4 is adapted to the shearing component 5, and different numbers of shearing components 5 can be placed as needed;

[0033] The steel grating shearing mechanism also includes:

[0034] The shearing component 5, the outer wall of the shearing component 5 is slidably connected to the inner wall of the mounting frame 4, and a corresponding number of shearing components 5 are installed according to the number of grids of the steel grating, and are placed in the mounting frame 4 and fixed to a determined position, and then fixed for unified shearing;

[0035] A limiting mechanism 6, the outer wall of the limiting mechanism 6 is fixedly connected to the inner wall of the operating table 1;

[0036] The bottom of the lifting column 3 is fixedly connected to the top of the operating platform 1. A discharge port 7 is provided on one side of the top of the operating platform 1 close to the collecting bucket 2. The discharge port 7 is located directly below the shearing component 5. Two limit rods 602 are symmetrically arranged, and two lifting columns 3 are symmetrically arranged.

[0037] When working, the worker places the steel grating on the operating table 1, and pushes the steel grating as needed so that the position to be sheared is located directly below the shearing component 5. The limiting mechanism 6 limits the steel grating so that the steel grating remains placed in the positive direction when approaching the shearing component 5. After reaching the specified position, the limiting mechanism 6 fixes one end of the steel grating to prevent the steel grating from tilting. Then, the shearing component 5 is driven by the lifting column 3 to move downward toward the steel grating, so that the shearing component 5 shears the steel grating, pushes the cut steel grating away, and then grinds the shearing surface. Finally, the cut steel grating is removed by the staff.

[0038] The shearing component 5 includes a driving block 501. The shape of the driving block 501 is adapted to the mounting frame 4. The driving block 501 can slide freely on the mounting frame 4 and be fixed at any position. The bottom of the driving block 501 is slidably connected to the inner wall of the mounting frame 4. The bottom of the driving block 501 is fixedly connected to a pop-up assembly 502. The inner wall of the driving block 501 away from the pop-up assembly 502 is fixedly connected to a moving knife assembly 503. The inner wall of one end of the driving block 501 away from the moving knife assembly 503 is rotatably connected to a fixed knife assembly 504.

[0039] After the steel grating strip is sheared to the position directly below the driving block 501, the lifting column 3 drives the driving block 501 to move downward. During the downward process, the fixed knife assembly 504 is inserted into the space of the steel grating and clamps the flat steel at both ends of the grid. The pop-up assembly 502 is inserted into the middle of the steel grating in front of the space to fix the steel grating near the shearing opening. Then the driving block 501 drives the moving knife assembly 503 to move downward and cooperates with the fixed knife assembly 504 to cut the flat steel. The fixed knife assembly 504 and the moving knife assembly 503 cut the fractures of the two steel gratings respectively. The cut steel grating is polished at the place where it is needed, and after the polishing is completed, the pop-up component 502 pushes out the cut steel grating to separate the two pieces of steel grating, ensuring that the steel grating is sheared completely before the staff moves away for unloading, to avoid the two pieces of steel grating being not completely separated, causing danger to the workers during transportation, and involving the unsheared steel grating. The fracture surfaces of the two sections of steel grating are polished separately to reduce burrs, further maintaining the safety of the staff during transportation, and the fixed knife component 504 is suitable for clamping gratings of different specifications, so that the moving knife can cut steel gratings of different specifications without the need to replace the knife multiple times.

[0040] The limiting mechanism 6 includes a hydraulic column 601, one end of which is fixedly connected to the inner wall of the operating table 1, and the other end of the hydraulic column 601 is fixedly connected to the limiting rod 602. The top of the limiting rod 602 is fixedly connected to a telescopic column 604, and the top of the telescopic column 604 is slidably connected to a connecting frame 605. The bottom of the connecting frame 605 is symmetrically provided with a shell 606. The clamping component 607 can move freely up and down inside the shell 606. When the shell 606 is driven by the connecting frame 605 to rotate, it drives the clamping component 607 to contact the grid of the steel grating. When it is located in the middle of the grid, the clamping Component 607 can fall onto the operating table 1 and is located inside the grid. The inner wall of the shell 606 is evenly provided with clamping components 607; the limiting mechanism 6 also includes an extrusion wheel 603, and multiple groups of extrusion wheels 603 are arranged at both ends of the limiting plate. The extrusion wheel 603 is made of hard rubber. The outer wall of the extrusion wheel 603 is rotatably connected to the inner wall of the limiting rod 602, and the top of the shell 606 is rotatably connected to the bottom of the mounting frame 4. The outer wall of the clamping component 607 is socketed with the inner wall of the shell 606. The top of the clamping component 607 is externally connected to an air pump, and the clamping component 607 and the air pump are connected by a pipe 6071.

[0041] When the steel grating is moved toward the shearing component 5, the limit rod 602 and the extrusion wheel 603 can keep the force on both ends of the steel grating uniform, so that the steel grating can remain in the middle of the operating table 1 during loading. When reaching the specified position, the telescopic column 604 drives the connecting frame 605 to move downward, so that the bottom of the shell 606 contacts the steel grating. Driven by the connecting frame 605, the clamping assembly 607 is placed in the middle of the grid of the steel grating, and then the air pump blows air, and the airflow drives the clamping assembly 607 to support the inside of the grid of the steel grating. Steel gratings of different models and grid sizes can be fixed and kept from warping during shearing, so that the steel grating maintains the same direction during loading and shearing, thereby enhancing stability.

[0042] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of Example 1, the pop-up component 502 includes a mounting plate 5021, the outer wall of the mounting plate 5021 is fixedly connected to the inner wall of the driving block 501, the outer wall of the mounting plate 5021 is rotatably connected to a connecting rod 5022, the connecting rod 5022 drives the rubber block 5023 to open and close freely, the end of the connecting rod 5022 away from the mounting plate 5021 is fixedly connected to the rubber block 5023, the outer wall of the rubber block 5023 is symmetrically provided with openings 5024, the bottom of the mounting plate 5021 is evenly provided with elastic rods 5025, the elastic rods 5025 are made of elastic material, the outer wall of the elastic rods 5025 is fixedly connected to the outer wall of the mounting plate 5021, and the end of the elastic rods 5025 away from the mounting plate 5021 is fixedly connected to an anti-sliding block 5026.

[0043] After the steel grating is moved to the appropriate position, the driving block 501 gradually approaches the steel grating, so that the mounting plate 5021 drives the connecting rod 5022, and the rubber block 5023 is inserted into the middle of the steel grating and pressed downward, so that the opening 5024 of the rubber block 5023 clamps the flat steel to increase the friction. At the same time, the elastic rod 5025 drives the protective block to be inserted into the gap of the steel grating. The protective block is against the inside of the flat steel, so that the elastic rod 5025 is squeezed, so that the protective block generates a clamping force with the rubber block 5023 under the squeezing force of the elastic rod 5025, so that the steel grating near the shearing mouth is fixed, and the stability during shearing is enhanced. When the shearing is completed, the movable knife assembly 503 and the fixed knife assembly 504 grind the shearing mouth, and the rubber block 5023 is lifted up. The squeezed elastic rod 5025 pushes the steel grating outward during the process of returning to its original state, which can not only help workers judge whether the steel grating is completely cut, but also keep the cut steel grating away from the uncut steel grating for easy transportation.

[0044] The movable knife assembly 503 includes a hydraulic rod 5031, the top of the hydraulic rod 5031 is fixedly connected to the top of the inner wall of the driving block 501, the bottom of the hydraulic rod 5031 is fixedly connected to a cutter 5033, the top of the cutter 5033 is fixedly connected to a Y-shaped air pipe 5032, the Y-shaped air pipe 5032 is externally connected to an air blowing device for blowing air to a grinding plate 5034, the inner wall of the cutter 5033 is fixedly connected to the grinding plate 5034, the top of the cutter 5033 is symmetrically provided with springs 5035, the top of the spring 5035 is fixedly connected to the outer wall of the cutter 5033, the bottom of the spring 5035 is fixedly connected to a cleaning block 5036, the outer wall of the cleaning block 5036 is in contact with the outer wall of the cutter 5033, and protruding rods are provided at both ends of the cleaning block 5036, and the length of the rods is greater than the grating length of the steel grating.

[0045] After the fixed knife 5044 clamps the flat steel at both ends of a grid of the steel grating, the hydraulic rod 5031 drives the cutting knife 5033 to move downward. After the cleaning block 5036 contacts the flat steel, it squeezes the spring 5035 in the process of gradually moving downward, and the movable knife continues to move downward. The flat steel on both sides of a grid is cut off by the shear force between it and the fixed knife 5044, and then continues to move downward under the drive of the hydraulic rod 5031, so that the grinding plate 5034 contacts the shearing edge and generates friction. The Y-shaped air pipe 5032 blows air to make the dust generated by grinding downward, reducing the dust attached to the steel grating, so that the burrs and sharp parts at the shearing edge are polished flat, making the shearing edge of the steel grating flat, and reducing the harm to workers during transportation. In the process of retracting the movable knife, the spring 5035 drives the cleaning block 5036 to clean the grinding plate 5034 from top to bottom, thereby extending the use time of the grinding plate 5034, saving the material requirements of the tool, and maintaining the shearing effect.

[0046] The fixed knife assembly 504 includes a rotating shaft 5041, the outer wall of the rotating shaft 5041 is rotatably connected to the inner wall of the driving block 501, the outer wall of the rotating shaft 5041 is fixedly connected to a bent rod 5042, the end of the bent rod 5042 away from the rotating shaft 5041 is fixedly connected to a mounting block 5043, the outer wall of the mounting block 5043 is symmetrically provided with fixed knives 5044, the fixed knives 5044 are provided in two groups, and when in use, they are respectively located outside two adjacent flat steels, so that the two groups of fixed knives 5044 are separated by two flat steels, the outer wall of the fixed knife 5044 is rotatably connected to the outer wall of the mounting block 5043, and the inner wall of the fixed knife 5044 is rotatably connected to a cleaning plate 5045.

[0047] As the driving block 501 gradually approaches the steel grating, the rotating shaft 5041 drives the mounting block 5043 to rotate 90 degrees, and then the mounting block 5043 drives the fixed knife 5044 to rotate, so that the fixed knife 5044 remains in a vertical state, and driven by the mounting block 5043, the fixed knife 5044 is located outside the two flat steels, and after being fixed, the moving knife is moved downward to achieve shearing. After the shearing is completed, the grinding plate 5034 grinds the shearing edge, and the cleaning plate 5045 cleans the other side of the grinding plate 5034. After use, the rotating shaft 5041 drives the fixed knife 5044 to retract into the driving block 501, and hides the tip to avoid scratches on equipment or staff due to external force during storage. Different types of steel gratings can be clamped and sheared with the moving knife to reduce the frequency of tool replacement, and the other end of the grinding plate 5034 is cleaned to maintain the grinding effect of the grinding plate 5034.

[0048] The clamping assembly 607 includes a pipe 6071, the outer wall of the pipe 6071 is sleeved with the inner wall of the shell 606, the inner wall of the pipe 6071 is provided with a groove 6072, the inner diameter of the groove 6072 is the same as the diameter of the extrusion block 6073 after being extruded, the inner wall of the groove 6072 is slidably connected with the extrusion block 6073, the outer wall of the extrusion block 6073 is evenly provided with connecting rods 6074, one end of the connecting rod 6074 is fixedly connected to the outer wall of the extrusion block 6073, and the end of the connecting rod 6074 away from the extrusion block 6073 is fixedly connected with a pad 6075, the pad 6075 is made of rubber, the outer wall of the pipe 6071 is evenly provided with a protective hose 6076, the protective hose 6076 is made of rubber, the outer wall of the protective hose 6076 is fixedly connected to the outer wall of the pipe 6071, and the inner wall of the protective hose 6076 is sleeved with the outer wall of the connecting rod 6074.

[0049] When the shell 606 drives the pipe 6071 to move, when the bottom of the pipe 6071 enters the grid, the pipe 6071 will fall downward due to the gravity of the pipe 6071, and then the air pump is turned on to pressurize the inside of the pipe 6071, so that the extrusion block 6073 is squeezed downward by the force of the air pressure, and the connecting rod 6074 is pushed outward, so that the pad 6075 contacts and supports the inner wall of the grid, so that the steel grating is fully fixed on the operating table 1 under the support force of the shell 606 and the pad 6075. It is suitable for steel gratings of different specifications, and the deformation of the steel grating is reduced through flexible clamping to maintain stability during the shearing process.

[0050] The specific workflow is as follows:

[0051] During work, the worker places the steel grating on the operating table 1, and pushes the steel grating as needed, so that the position to be sheared is located directly below the shearing component 5. When the steel grating is moved toward the shearing component 5, the limit rod 602 and the extrusion wheel 603 can keep the force on both ends of the steel grating uniform, so that the steel grating can be kept in the middle of the operating table 1 when loading. When reaching the designated position, the telescopic column 604 drives the connecting frame 605 to move downward, so that the bottom of the shell 606 contacts the steel grating. Driven by the connecting frame 605, the clamping assembly 607 is placed in the middle of the grid of the steel grating, and then the air pump blows air, and the airflow drives the clamping assembly 607 to support the inside of the grid of the steel grating.

[0052] After the shearing position of the steel grating is moved to just below the driving block 501, the lifting column 3 drives the driving block 501 to move downward. During the downward process, the fixed knife assembly 504 is inserted into the space of the steel grating and clamps the flat steels at both ends of the grating. The pop-up assembly 502 is inserted into the middle of the steel grating in front of the space to fix the steel grating near the shearing opening. Then the driving block 501 drives the moving knife assembly 503 to move downward and cooperates with the fixed knife assembly 504 to cut the flat steel. The fixed knife assembly 504 and the moving knife assembly 503 grind the fracture of the two sections of the steel grating respectively. After the grinding is completed, the pop-up assembly 502 pushes out the cut steel grating to separate the two sections of the steel grating, ensuring that the steel grating is completely sheared before the staff moves the material away, avoiding the incomplete separation between the two sections of the steel grating causing danger to the workers during transportation, involving the unsheared steel grating, and grinding the fractures of the two sections of the steel grating respectively, and finally the staff removes the sheared steel grating.
