The presence of the cleaning roller 8 can reduce the amount of dust at the connection between the web and the wing plate, thereby ensuring the strength of the H-shaped steel after welding.

[0022] Specifically, refer to Figure 1-Figure 8 The connecting assembly 7 includes a rotating shaft 9, which is rotatably arranged in the mounting frame 5.

A slider 12 is slidably arranged on the limit frame 11. A limit block 13 is fixedly arranged on the top of the limit frame 11. The slider 12 is slidably matched with a slide groove arranged in the mounting frame 5. A tooth groove 14 meshing with the rolling gear 10 is opened on the side of the slider 12 close to the rolling gear 10. Both ends of the rotating shaft 9 pass through the mounting frame 5 and are fixedly provided with symmetrically distributed bevel gears 15. The mounting frame A symmetrically distributed support plate 16 is fixedly arranged on the outside of the support plate 16, an auxiliary shaft 17 is rotatably arranged on the top of the support plate 16, a bevel gear 2 18 meshing with the bevel gear 1 15 is fixedly arranged on the top of the auxiliary shaft 17, an auxiliary gear 19 is fixedly arranged on the outside of the auxiliary shaft 17, a sliding opening 20 is arranged inside the mounting frame 5, a symmetrically distributed sliding frame 21 is slidably arranged inside the sliding opening 20, a tooth groove 22 meshing with the auxiliary gear 19 is arranged on the side of the sliding frame 21 close to the auxiliary gear 19, and both ends of the clamping plate 4 are respectively fixed to the sliding frames 21 symmetrically arranged between the two mounting frames 5; The support member 3 includes a support block 23 for supporting the web and a sliding block 24 for supporting the wing. The support block 23 is fixed to the support plate 2. The support plate 2 is provided with symmetrically distributed sink grooves 42. The sink grooves 42 are slidably provided with symmetrically distributed embedded blocks 25. The embedded blocks 25 are fixed to the sliding block 24. It is worth noting that reference Figure 2 , Figure 4 and Figure 8 As shown, a fixing groove is provided at the bottom of the slider 12, and a compression spring 39 is fixed in the fixing groove. The bottom of the compression spring 39 is fixed to the inner bottom of the mounting frame 5. The setting of the compression spring 39 can buffer the descent of the web and reduce the descent speed of the web.

[0023] The principle of assembling the web and the wing plate by the connecting component 7 is as follows: first, the two wing plates are respectively embedded in the embedding grooves of the sliding block 24, and then the web is placed on the support plate 2 by the traveling crane, and the web is lowered, and the two ends of the web are pressed on the two movable plates 6. Under the action of the web's own weight, the web presses the movable plates 6 to move downward until the limit block 13 on the limit frame 11 connected to the movable plate 6 is against the top of the slider 12. As the web continues to move downward, the slider 12 moves downward accordingly, and the tooth groove 14 on the outer side of the slider 12 drives the rolling gear 10 to rotate through the meshing action, and the rolling gear 10 is driven by the slider 12 with the shaft 9. Rotate, thereby driving the auxiliary shaft 17 to rotate through the meshing action of the bevel gear 15 and the bevel gear 2 18 at both ends of the rotating shaft 9, and then driving the auxiliary gear 19 on the auxiliary shaft 17 to rotate, and utilizing the meshing action of the auxiliary gear 19 symmetrically arranged on the mounting frame 5 and the tooth groove 2 22 to drive the two symmetrically arranged sliding frames 21 to move toward each other, thereby driving the two clamping plates 4 arranged above the support plate 2 to move toward each other, and driving the two wing plates to move toward the web plate, and finally the web plate moves to the lowest support block 23 and stops moving, and the two wing plates are pressed against the two sides of the web plate by the pressure of the clamping plate 4, completing the assembly of the H-shaped steel.

[0024] At the same time, reference Figure 2-Figure 7 An auxiliary plate 26 is provided between the two mounting frames 5, a placement groove 27 is provided inside the auxiliary plate 26, a pressing frame 28 is slidably provided inside the placement groove 27, a cleaning roller 8 is provided inside the pressing frame 28, and an auxiliary component 29 for pushing the pressing frame 28 is provided outside the mounting frame 5; The cleaning roller 8 is cylindrical and is rotatably arranged in the pressing frame 28. The cleaning roller 8 is pressed against the outer side of the web. When the web moves downward, the cleaning roller 8 is driven by friction to roll on the outer side of the web, so that the dust on the outer side of the web can be removed without affecting the normal descent of the web. In addition, the auxiliary component 29 includes an air supply pipe 30, a sealing box 31 is fixedly provided on the top of the slider 12, a limit block 13 is slidably provided in the sealing box 31, and the limit block 13 is sealed with the inner wall of the sealing box 31 on all sides, an air outlet pipe 32 is fixedly provided on the outer side of the bottom of the sealing box 31, and a plurality of connecting pipes 33 are fixedly provided on the outer side of the auxiliary plate 26. The air supply pipe 30 is provided on the outer side of the auxiliary plate 26, and one end of the connecting pipe 33 away from the auxiliary plate 26 is connected and fixed to the air supply pipe 30, and one end of the air outlet pipe 32 away from the sealing box 31 is fixedly connected to the end of the air supply pipe 30, and a piston plate 34 is slidably provided in the connecting pipe 33, and a piston rod 35 is fixedly provided on the side of the piston plate 34 close to the placement groove 27, and the piston rod 35 passes through the inner side of the placement groove 27 and is fixedly connected to the pressure frame 28, and a second compression spring 36 is fixedly provided on the side of the piston plate 34 close to the piston rod 35, and the second compression spring 36 is fixed to the auxiliary plate 26; It is worth noting that a mounting opening 37 is provided on the side of the mounting frame 5, and both ends of the auxiliary plate 26 cooperate with the mounting opening 37, so as to facilitate the subsequent removal of the H-shaped steel; The principle of the auxiliary component 29 cleaning the dust on the outer side of the web is as follows: before the slider 12 moves downward with the web, the web drives the movable plate 6 and the limit frame 11 to move downward, thereby driving the limit block 13 on the top of the limit frame 11 to move downward in the sealing box 31. Since the limit block 13 is sealed and connected to the inside of the sealing box 31 on all sides, the air at the bottom of the sealing box 31 is squeezed during the downward movement of the limit block 13, and the air at the bottom of the sealing box 31 is squeezed into the air supply pipe 30 through the air outlet pipe 32, thereby increasing the air pressure in the air supply pipe 30. The increased air pressure in the air supply pipe 30 squeezes the piston plate 34, driving the piston plate 34 and the piston rod 35 to squeeze the pressing frame 28, pushing the cleaning roller 8 in the pressing frame 28 to press against the outer side of the web, ensuring the tightness of the cleaning roller 8 when in contact with the web, thereby ensuring the cleaning effect of the cleaning roller 8 on the dust on the outer side of the web. As the web moves downward, the cleaning roller 8 rolls on the outer side of the web under the action of friction to clean the dust adhering to the outer side of the web.

[0025] In the present technical solution, the mounting frame 5 is rotatably connected to the fixing frame 1, a motor 40 is fixedly provided on the outer side of the fixing frame 1, the output end of the motor 40 is fixed to the mounting frame 5, a pneumatic hydraulic rod 41 is fixedly provided on the inner bottom of the fixing frame 1, the output end of the pneumatic hydraulic rod 41 is fixed to the bottom of the support plate 2, and at the same time, the spacing between the bottom of the auxiliary plate 26 and the support plate 2 is equal to the width of the wing plate, and when the wing plate is attached to the outer side of the web, the wing plate is clamped and limited between the auxiliary plate 26 and the support plate 2.

[0026] The two wing plates are respectively embedded in the embedding grooves of the sliding block 24, and then the web plate is placed above the support plate 2 by the traveling crane, and the web plate is lowered, and the two ends of the web plate are pressed on the two movable plates 6. Under the action of the web plate's own weight, the web plate presses the movable plate 6 downward, thereby driving the limit block 13 on the top of the limit frame 11 to move downward in the sealing box 31. Since the limit block 13 is sealed and connected to the inside of the sealing box 31 on all sides, the air at the bottom of the sealing box 31 is squeezed during the downward movement of the limit block 13, and the air at the bottom of the sealing box 31 is squeezed into the air supply pipe 30 through the air outlet pipe 32, thereby increasing the air pressure in the air supply pipe 30. The increase in air pressure in the air supply pipe 30 squeezes the piston plate 34, drives the piston plate 34 and the piston rod 35 to squeeze the pressing frame 28, and pushes the cleaning roller 8 in the pressing frame 28 to press against the outer side of the web plate, to ensure the tightness of the cleaning roller 8 when in contact with the web plate. At this time, the limit frame connected to the movable plate 6 The limit block 13 on 11 is against the top of the slider 12. As the web continues to move downward, the slider 12 moves downward accordingly. The tooth groove 14 on the outer side of the slider 12 drives the rolling gear 10 to rotate through meshing. The rolling gear 10 drives the rotating shaft 9 to rotate under the drive of the slider 12, thereby driving the auxiliary shaft 17 to rotate through the meshing of the bevel gear 15 and the bevel gear 2 18 at both ends of the rotating shaft 9, and then driving the auxiliary gear 19 on the auxiliary shaft 17 to rotate, and utilizing the meshing of the auxiliary gear 19 symmetrically arranged on the mounting frame 5 and the tooth groove 22 to drive the two symmetrically arranged sliding frames 21 to move toward each other, thereby driving the two clamping plates 4 arranged above the support plate 2 to move toward each other, and driving the two wing plates to move toward the web, and finally the web moves to the lowest support block 23 and stops moving, and the two wing plates are pressed against both sides of the web by the clamping plate 4, completing the assembly of the H-shaped steel; In the process of the web driving the slider 12 to move downward, the cleaning roller 8 is against the outer side of the web. Under the action of the friction between the cleaning roller 8 and the web, the cleaning roller 8 rolls on the outer side of the web as the web moves downward, cleaning the dust adhered to the outer side of the web, thereby improving the quality of the H-shaped steel after the subsequent web plate fish wing plate assembly welding; After the workers weld one side of the H-beam, the wing plate and the web are fixed together. Since the top of the wing plate abuts against the bottom of the auxiliary plate 26 and the bottom of the web abuts against the movable plate 6, the H-beam is limited between the two mounting frames 5. The pneumatic hydraulic rod 41 drives the support plate 2 to move downward until the rotation of the mounting frame 5 is not disturbed. Then the motor 40 drives the mounting frame 5 and the H-beam between the two mounting frames 5 to rotate 180°, and the side that has not been welded is rotated upward. Then the workers perform spot welding on this surface, thereby completing the welding operation of the H-beam. After the welding operation is completed, the welded H-beam can be released by pulling the auxiliary plate 26 out of the mounting opening 37 so that the H-beam can be removed.

[0027] During the downward movement of the web, the present solution can not only move the wing plate toward the web, but also drive the cleaning roller 8 to clean the dust on the outside of the web. At the same time, the auxiliary plate 26 for installing the cleaning roller 8 can also, together with the movable plate 6, provide limited support for the H-shaped steel composed of the wing plate and the web after the wing plate and the web are welded together, so as to facilitate the subsequent flipping of the H-shaped steel as a whole.

[0028] Embodiment 2: This embodiment further describes the embodiment 1, and the difference lies in the optimization of the connection between the auxiliary plate 26 and the mounting opening 37; Specifically, the two ends of the auxiliary plate 26 are embedded in the installation port 37 through latex rings. The elasticity of the latex rings can ensure the tightness of the connection between the auxiliary plate 26 and the installation port 37. At the same time, the friction between the auxiliary plate 26 and the installation port 37 can be increased to prevent the auxiliary plate 26 from falling off accidentally.

[0029] Embodiment 3: This embodiment further illustrates other embodiments, and the difference lies in the optimization of the cleaning roller 8; Specifically, the cleaning roller 8 and the pressing frame 28 are connected in a detachable manner, such as a bolt connection, so that the cleaning roller 8 can be easily replaced and maintained.
