Description

Technical Field

[0001] This invention belongs to the field of marine engineering equipment manufacturing technology, and in particular relates to an H-beam steel overturning auxiliary device. Background Technology

[0002] Robotic grinding after steel section cutting is an important part of steel structure processing. It is the follow-up process to steel section chamfering and a key process before intelligent robot welding. It is closely connected with the intelligent robot welding system. The H-section steel intelligent grinding robot system performs pre-welding grinding on the area near the welding position of the steel section after plasma / flame cutting, with a grinding area of ​​not less than 25mm.

[0003] Currently, there is no mature technology for H-beam steel grinding robot equipment at home and abroad. We need to independently develop intelligent grinding robot systems to meet the grinding position requirements, grinding quality requirements, and grinding depth requirements of steel before welding, effectively reduce labor and material costs, and achieve the goal of cost reduction and efficiency improvement.

[0004] While some automated grinding equipment exists in the current technology, there are still shortcomings in the steel section turning process. The turning accuracy, efficiency, and adaptability need to be improved, especially for large, heavy, and non-standard end H-beams, where the performance of the turning system directly affects the working effect of the grinding robot.

[0005] Traditional flipping devices have the following problems: (1) Manual operation is inefficient; (2) The flipping angle is limited, requiring a second flipping, which takes a long time; (3) Large steel sections are prone to instability and poor synchronization when flipped, resulting in insufficient grinding precision; (4) Lack of coordinated control with grinding robots makes it difficult to adapt to the processing needs of discrete non-standard workpieces.

[0006] Therefore, there is an urgent need to design an H-beam turning aid device to solve the problems mentioned above. Summary of the Invention

[0007] To address the technical problems mentioned in the background art, such as the need for manual operation of traditional flipping devices, low efficiency, limited flipping angle, the need for secondary flipping, and long flipping time, an H-beam flipping auxiliary device is provided to solve the problem of H-beam flipping and grinding.

[0008] To achieve the above objectives, the specific technical solution of the H-beam steel turning auxiliary device of the present invention is as follows: An H-beam turning auxiliary device includes a turning body, on which a first lifting frame and a second lifting frame are symmetrically arranged. The first lifting frame and the second lifting frame are respectively provided with clamping structures. The first lifting frame and the second lifting frame are moved to clamp the H-beam through the clamping structures. The turning body is rotatably mounted on a base. Rotating the turning body causes the H-beam to rotate. The side of the base away from the turning body is connected to a slide table so that after the H-beam is turned into place, the turning body is moved away from the H-beam along the slide table.

[0009] Furthermore, the flip-up body has an opening to make it C-shaped.

[0010] Furthermore, a first lifting frame and a second lifting frame are symmetrically provided on the opening of the flipping main body.

[0011] Furthermore, a first lifting rod and a second lifting rod are symmetrically provided on the opening of the flipping body, and the first lifting rod and the second lifting rod drive the first lifting frame and the second lifting frame to move respectively.

[0012] Furthermore, the first lifting frame and the second lifting frame are respectively provided with clamping structures on the side away from the first lifting rod and the second lifting rod, so that the first lifting frame and the second lifting frame can move to clamp the H-beam.

[0013] Furthermore, the tilting body is rotatably mounted on the base via a gear transmission mechanism, so that the tilting body drives the H-beam to rotate.

[0014] Furthermore, the base is provided with a first drive structure, which is connected to a gear transmission mechanism to make the flipping body rotate.

[0015] Furthermore, a rack and pinion drive mechanism is provided on the side of the base away from the flipping body. The rack and pinion drive mechanism is connected to the slide table so that the flipping body can move along the length of the slide table.

[0016] Furthermore, a second drive structure is provided on the side of the base away from the first drive structure. The second drive structure is connected to the rack and pinion transmission mechanism so that the base is slidably mounted on the slide.

[0017] The H-beam turning aid device of the present invention has the following advantages: (1) The present invention can achieve high-precision flipping, realize high progress control of flipping angle, and ensure the accuracy and consistency of grinding operation.

[0018] (2) The present invention has a strong load-bearing capacity, enabling it to handle marine engineering steel of various specifications and weights, thus expanding the applicable scenarios of the equipment.

[0019] (3) The present invention can achieve efficient operation, greatly reduce the turning time of a single steel section, and the turning speed is adjustable, effectively improving the production efficiency of steel section grinding and reducing the processing cycle.

[0020] (4) The present invention has good scalability. The flipping body can move flexibly in the grinding area and work in coordination with the grinding robot to expand the work space and enhance the flexibility of operation.

[0021] (5) The present invention is stable and reliable, and can guarantee stability and reliability under long-term and high-intensity operation, thereby reducing failure rate and maintenance cost. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0026] The following is a reference to the appendix. Figure 1 To be continued Figure 2 The present invention describes an H-beam steel flipping auxiliary device.

[0027] like Figure 1As shown, the H-beam turning auxiliary device of the present invention includes a turning body 1, on which a first lifting frame 2 and a second lifting frame 3 are symmetrically arranged. The first lifting frame 2 and the second lifting frame 3 are respectively provided with a clamping structure 4. The first lifting frame 2 and the second lifting frame 3 are moved to clamp the H-beam through the clamping structure 4. The turning body 1 is rotatably mounted on the base 5. The turning body 1 is rotated to make the H-beam rotate. The side of the base 5 away from the turning body 1 is connected to the slide table 6 so that after the H-beam is turned into place, the turning body 1 is moved away from the H-beam along the slide table 6.

[0028] By flipping the main body 1, it can move flexibly within the grinding area, work in conjunction with the grinding robot, expand the workspace, and enhance operational flexibility.

[0029] In a preferred embodiment, multiple roller conveyors are spaced apart at the construction site. These roller conveyors are arranged in a straight line to transport H-beams to be ground. A grinding robot is installed on the side of the roller conveyor to perform grinding operations on designated positions of the H-beams.

[0030] A sliding table 6 is laid at the interval between the roller conveyors. When the H-beam needs to be flipped, the flipping body 1 slides through the base 5, so that the H-beam is located in the opening of the flipping body 1. The first lifting frame 2 and the second lifting frame 3 are driven to move simultaneously to clamp the H-beam. Then, the flipping body 1 is rotated so that the H-beam can be flipped and placed on the roller conveyor for further grinding. When the H-beam needs to be moved, the flipping body 1 slides away from the H-beam through the base 5 so that the ground H-beam can continue to move along the roller conveyor.

[0031] Furthermore, such as Figure 2 As shown, the flipping body 1 has a rectangular opening so that the flipping body 1 is set in a C-shape to ensure that it matches the size of the H-beam to be ground.

[0032] Specifically, a first lifting frame 2 and a second lifting frame 3 are symmetrically arranged on the opening of the flipping body 1. When the flipping body 1 is in the initial state, the first lifting frame 2 is located above the second lifting frame 3 in the vertical direction.

[0033] Preferably, a first lifting rod 7 and a second lifting rod 8 are symmetrically arranged on the opening of the flipping body 1. The output end of the first lifting rod 7 is connected to the first lifting frame 2, and the output end of the second lifting rod 8 is connected to the second lifting frame 3. The first lifting rod 7 and the second lifting rod 8 respectively drive the first lifting frame 2 and the second lifting frame 3 to move, thereby changing the distance between the first lifting frame 2 and the second lifting frame 3.

[0034] Meanwhile, the first lifting frame 2 and the second lifting frame 3 are respectively provided with clamping structures 4 on the side away from the first lifting rod 7 and the second lifting rod 8, so as to realize the movement of the first lifting frame 2 and the second lifting frame 3 to clamp the H-beam.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the flipping body 1 is rotatably mounted on the base 5 through the gear transmission mechanism 9, so that the flipping body 1 can rotate, thereby driving the H-beam to flip.

[0036] Preferably, the base 5 is provided with a first driving structure 11, that is, the upper end face of the base 5 is provided with a first driving structure 11, the first driving structure 11 is connected to the gear transmission mechanism 9, thereby driving the flipping body 1 to rotate, and the rotation angle of the flipping body 1 can reach -120 degrees to 180 degrees.

[0037] Furthermore, such as Figure 2 As shown, a rack and pinion transmission mechanism 10 is provided on the side of the base 5 away from the flipping body 1. The base 5 is connected to the slide table 6 through the rack and pinion transmission mechanism 10, so that the base 5 can be slidably set on the slide table 6, so that the flipping body 1 can move along the length direction of the slide table 6 and detach from the H-beam.

[0038] A second driving structure 12 is provided on the side of the base 5 away from the first driving structure 11, that is, the second driving structure 12 is provided at the bottom end of the base 5. The second driving structure 12 is connected to the rack and pinion transmission mechanism 10 and drives the base 5 to slide.

[0039] The working principle of the H-beam turning aid device in this invention is as follows: First, the flipping body 1 moves along the slide table 6 via the base 5, so that the H-beam is located in the opening of the flipping body 1; Then, the first lifting rod 7 and the second lifting rod 8 respectively drive the first lifting frame 2 and the second lifting frame 3 to move and approach each other; Then, the first lifting frame 2 and the second lifting frame 3 respectively fix the two sides of the H-beam through the clamping mechanism 4; Then, the gear transmission mechanism 9 drives the tilting body 1 to rotate, which in turn drives the H-beam to rotate; Finally, after the H-beam rotates into place, the first lifting rod 7 and the second lifting rod 8 drive the first lifting frame 2 and the second lifting frame 3 to move away, and put the H-beam back onto the roller conveyor.

[0040] Based on the H-beam turning auxiliary device, this invention is stable and reliable, ensuring stability and reliability under long-term, high-intensity operation, and reducing failure rate and maintenance costs.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
