DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 3 In an embodiment of the present invention, a steel structure construction device includes a base 1, and the steel structure includes columns and beams. A placement plate 2 for clamping and fixing the columns is provided on one side of the upper end of the base 1, and a guide rail 7 is fixedly connected to the side of the upper end of the base 1 away from the placement plate 2. The upper end of the guide rail 7 is provided with a fixing mechanism for clamping and fixing the beam, and the lower end of the fixing mechanism is slidably connected to the bottom of the inner cavity of the guide rail 7. A first electric push rod 8 is fixedly connected to the side of the upper end of the base 1 close to the guide rail 7, and the output end of the first electric push rod 8 is transmission-connected to the side of the fixing mechanism away from the placement plate 2. When the output end of the first electric push rod 8 pushes the fixing mechanism to horizontally approach the placement plate 2, the top end of the fixing mechanism will horizontally approach the center position of the placement plate 2.

[0031] See also Figure 2-Figure 4The fixing mechanism includes a placement table 9, the lower end of the placement table 9 is horizontally slidably connected to the guide rail 7, a symmetrical moving groove 33 is provided in the middle of the upper end of the placement table 9, and a moving rod 17 is horizontally slidably connected to the inner cavity of the moving groove 33, and a guide rod 16 is fixedly connected to the middle of the lower end of the moving rod 17. A driving plate 10 is horizontally slidably connected to the side of the lower part of the placement table 9 close to the first electric push rod 8, and the end of the driving plate 10 away from the placement table 9 is transmission-connected to the output end of the first electric push rod 8, and the first electric push rod 8 will push the driving plate 10 to move horizontally, and a symmetrical guide groove 15 is provided at the upper end of the driving plate 10, and the inner cavity of the guide groove 15 is slidably matched with the outer wall of the end of the guide rod 16 away from the moving rod 17, that is, when the first electric push rod 8 pushes the driving plate 10 horizontally close to the direction where the placement plate 2 is located, the guide groove 15 will slide and cooperate with the guide rod 16 to drive the guide rod 16 to move horizontally toward the center position of the placement table 9, through the guide groove 15 and the guide rod 16 The cooperation can drive the moving rod 17 to horizontally approach the center position of the placement table 9 in the inner cavity of the moving groove 33. The middle part of the upper end of the inner cavity of the moving rod 17 is rotatably connected with a rotating rod 34, and the end of the rotating rod 34 away from the moving rod 17 is fixedly connected with a clamping block 11. When clamping and fixing the beam, the beam is first placed in the middle part of the upper end of the placement table 9, and then the driving plate 10 is driven to move horizontally by the first electric push rod 8, so that the moving rod 17 is driven to drive the clamping block 11 to horizontally approach the center position of the placement table 9 through the sliding cooperation between the guide groove 15 and the guide rod 16, so as to clamp and fix the beam. After the symmetrical clamping block 11 is in close contact with the outer wall of the beam, the guide groove 15 can no longer continue to drive the moving rod 17 and the clamping block 11 to move horizontally through the guide rod 16. At this time, the force applied to the driving plate 10 will be transmitted to the placement table 9 through the guide groove 15. At this time, the driving plate 10 will push the placement table 9 to move horizontally, thereby driving the horizontal movement of the beam through the placement table 9.

[0032] During the installation of steel structure houses, some beams are inclined. During the process of clamping and fixing the beams, if the clamping block cannot rotate, the clamping block cannot fit with the beam, resulting in the inability to stably clamp and fix the beam. The clamping block 11 is fixedly connected to the rotating rod 34, and the rotating rod 34 rotates with the moving rod 17. In the process of the moving rod 17 driving the clamping block 11 to approach the inclined beam, the two sides of the clamping block 11 cannot contact the side wall of the inclined beam at the same time. The side of the clamping block 11 that is not in contact with the side wall of the beam deflects toward the position of the beam until the clamping block 11 is completely in contact with the side wall of the beam.

[0033] In order to prevent the first electric push rod 8 from moving the placement table 9 in advance after the clamping block 11 has not completely contacted the side wall of the beam during the process of pushing the driving plate 10 to move, a symmetrical clamping block 12 is vertically slidably connected to one side of the inner cavity of the guide rail 7 near the first electric push rod 8, and a slide groove for cooperating with the clamping block 12 is provided at the bottom of the inner cavity of the guide rail 7. The lower end of the clamping block 12 is elastically connected to the inner cavity bottom of the slide groove by a spring, and a clamping groove for cooperating with the clamping block 12 is provided at the bottom of the inner cavity of the placement table 9. When the placement table 9 is in the initial position, that is, when the first electric push rod 8 does not push the placement table 9 to move, the clamping block 12 is clamped in the clamping groove, thereby limiting and fixing the position of the placement table 9, and a driven rod 14 is vertically slidably connected to the upper part of the inner cavity of the clamping groove, and the spacing between the symmetrical driven rods 14 is greater than the horizontal width of the driving plate 10, and an adapting groove 18 is provided in the middle part of the lower side of the moving rod 17, and a connecting rod 13 is vertically slidably connected to the lower part of the inner cavity of the moving groove 33. The connecting rod 13 passes through the adapting groove 18. The matching groove 18 is slidably matched with the inner cavity side wall of the matching groove 18, that is, through the matching of the connecting rod 13 and the matching groove 18, during the horizontal movement of the moving rod 17, the connecting rod 13 will not affect the movement process of the moving rod 17, and the lower side of the end of the connecting rod 13 close to the block 12 is fixedly connected to the end of the driven rod 14 away from the block 12, and the length of the driven rod 14 is greater than the length of the block 12. During the downward movement of the connecting rod 13, the driven rod 14 will be driven to move downward synchronously. During the downward movement, 14 will push the block 12 to move down to the inner cavity of the slide groove, and because the length of the driven rod 14 is greater than the length of the slide groove, when the driven rod 14 completely pushes the block 12 to the inner cavity of the slide groove, the driven rod 14 will not enter the slide groove, thereby pushing the connecting rod 13 downward to push the block 12 to separate from the slot through the driven rod 14, thereby releasing the limit of the block 12 on the placement table 9, so that the placement table 9 can move horizontally after the clamping block 11 clamps and fixes the crossbeam.

[0034] See also Figure 5-Figure 6The side of the clamping block 11 close to the first electric push rod 8 is horizontally slidably connected with a symmetrical push plate 19, and the side of the symmetrical push plate 19 away from the first electric push rod 8 is fitted with a rotating plate 20. The side of the rotating plate 20 away from the push plate 19 is elastically connected to the inner cavity side wall of the clamping block 11 through a symmetrical spring. The rotating plate 20 is horizontally slidably connected to the middle part of the inner cavity of the clamping block 11. A mounting cavity 21 is provided in the middle part of the inner cavity of the clamping block 11. A fixing plate 25 is vertically slidably connected to the bottom of the inner cavity of the mounting cavity 21. A symmetrical support rod 23 is fixedly connected to the side wall of the inner cavity of the mounting cavity 21 away from the rotating plate 20. A rotating rod 22 is slidably connected to the outer wall of the symmetrical support rod 23 close to the rotating plate 20. The rotating rod 22 is rotatably connected to the middle part of the upper end of the rotating plate 20. When squeezed at the same time, the rotating plate 20 will be pushed to drive the rotating rod 22 to move synchronously toward the inner cavity of the clamping block 11, that is, when the push plate 19 on one side is forced to move toward the inner cavity of the clamping block 11, at this time, only one side of the rotating plate 20 is squeezed, then at this time, the rotating plate 20 will rotate around the center position of the rotating rod 22, and will not drive the rotating rod 22 to move synchronously in the direction away from the push plate 19. In the process of rotation of the rotating plate 20, the push plate 19 that is not subjected to force will be squeezed by the side wall of the rotating plate 20, thereby moving toward the center position of the placement table 9. After the clamping block 11 rotates, the squeezed push plate 19 will also move relatively toward the inner cavity of the clamping block 11. At this time, since the rotating plate 20 cannot rotate again, it will drive the rotating rod 22 to move synchronously toward the inner cavity of the clamping block 11.

[0035] See also Figure 7 The lower end of the rotating rod 22 is fixedly connected with a slide plate 28 on the side away from the push plate 19, and the upper end of the fixed plate 25 is fixedly connected with a driven block 24. A groove 27 is provided in the middle of the upper end of the driven block 24, and both sides of the slide plate 28 are in contact with the side walls of the groove 27. A symmetrical round rod 29 is fixedly connected to the end of the slide plate 28 away from the rotating rod 22. An inclined groove 30 used to cooperate with the round rod 29 is provided on the side wall of the groove 27. The outer wall of the end of the round rod 29 away from the slide plate 28 is slidably matched with the inner cavity of the inclined groove 30. A symmetrical balancing groove 31 is provided on the outer wall of the driven block 24 away from the rotating plate 20. A symmetrical balancing rod 32 is fixedly connected to the side wall of the inner cavity of the installation cavity 21. The balancing rod 32 and the balancing groove 31 are in contact with each other. The positions correspond to each other, and the balance bar 32 slides with the balance groove 31. Through the symmetrical sliding cooperation between the balance bar 32 and the balance groove 31, the driven block 24 is more stable during the vertical movement. The inclined groove 30 is inclined toward the direction of the balance bar 32. When the rotating plate 20 drives the rotating rod 22 to move horizontally toward the position of the balance bar 32, the sliding plate 28 will be driven by the rotating rod 22 to synchronously approach the position of the balance bar 32. Through the cooperation of the round rod 29 and the inclined groove 30, the driven block 24 can be driven to move downward in the vertical direction during the horizontal movement of the rotating rod 22 and the sliding plate 28, thereby driving the fixed plate 25 to move downward in the vertical direction through the driven block 24.

[0036] See also Figure 8-Figure 10 A symmetrical driven plate 26 is fixedly connected to the middle of the lower end of the fixed plate 25. The outer wall of the driven plate 26 is slidably connected to the clamping block 11 and the moving rod 17. The lower end of the driven plate 26 passes through the upper part of the moving rod 17 and fits the upper end surface of the connecting rod 13. The outer wall of the toothed ring 35 away from the clamping block 11 is fixedly connected to the toothed ring 35. The outer wall of the toothed ring 35 is provided with a plurality of limiting grooves 39. The middle part of the driven plate 26 is fixedly connected to the side close to the rotating rod 34. The extension rod 37 is far away from the extension rod 37. A limit block 36 is fixedly connected to the lower side of one end of the driven plate 26, and the size of the limit block 36 is adapted to the limit groove 39. After the clamping block 11 is completely in contact with the side wall of the beam, the symmetrical push plate 19 pushes the rotating plate 20 and the rotating rod 22 to move horizontally, thereby driving the driven block 24 to move vertically downward through the cooperation of the round rod 29 and the inclined groove 30, and the fixed plate 25 and the driven plate 26 are driven vertically downward through the driven block 24. In the process of the driven plate 26 moving downward, it will drive the limit block 36 close to The gear ring 35 is located at a position and is engaged with the limiting groove 39 to limit and fix the gear ring 35, thereby limiting and fixing the rotating rod 34 to prevent the clamping block 11 from rotating, and the downward-moving driven plate 26 will push the connecting rod 13 to move vertically downward, thereby pushing the clamping block 12 into the sliding groove through the driven rod 14, so that the clamping block 12 is separated from the groove and no longer limits and fixes the placement table 9, thereby achieving that in the process of the first electric push rod 8 pushing the driving plate 10 to move, the guide groove 1 The movable rod 17 driven by the guide rod 16 drives the clamping block 11 to approach the side wall of the beam, and the clamping block 11 rotates to adapt to the inclined surface of the beam. When the clamping block 11 is completely fitted with the side wall of the beam, the limiting block 36 cooperates with the limiting groove 39 to limit the gear ring 35 so that the position of the clamping block 11 remains fixed. At the same time, the connecting rod 13 is pushed to move by the downward driven plate 26, so that after the beam is fixed, the placement table 9 can be horizontally moved close to the position of the placement plate 2.

[0037] The middle part of the upper end of the placement plate 2 is horizontally slidably connected with a clamping plate 3, and the middle part of the side of the clamping plate 3 away from the placement plate 2 is transmission-connected with a second electric push rod 38. The second electric push rod 38 pushes the clamping plate 3 to move horizontally to clamp and fix columns of different sizes. In the process of docking and installing the column and the beam, the beam and the column are clamped and fixed respectively by the symmetrical clamping blocks 11 and the clamping plates 3, and then the ends of the two are brought close to each other and installed and fixed by bolts. That is, after the column is fixed by the cooperation of the placement plate 2 and the clamping plate 3, and the beam is clamped and fixed by the symmetrical clamping blocks 11, the first electric push rod 8 pushes the placement table 9 to move horizontally, thereby driving the beam to move horizontally close to the position of the column. For the inclined beam, when it is clamped and fixed close to the column, the installation hole opened at its end may not necessarily be aligned with the horizontal column, so it is necessary to rotate the column at a certain angle so that the vertical planes where the column and the center of the beam are located are perpendicular to each other, thereby ensuring that the installation holes opened at the ends of the column and the beam can be aligned for easy installation and fixation. A rotating column 4 is fixedly connected to the middle of the lower end of the placement plate 2, and the lower end of the rotating column 4 is rotatably connected to the base 1. A driven gear 5 is fixedly connected to the lower outer wall of the rotating column 4, and a driving gear 6 is provided on one side of the driven gear 5. The driving gear 6 meshes with the driven gear 5, and the transmission ratio of the driven gear 5 and the driving gear 6 is greater than 2:1. The lower end of the driving gear 6 The transmission is connected with a servo motor, which is installed in the inner cavity of the base 1. The vertical slot end of the servo motor passes through the upper end surface of the base 1 and is fixedly connected to the middle part of the driving gear 6. The driving gear 6 is driven by the servo motor to rotate, thereby driving the driven gear 5 to rotate through the driving gear 6. The driven gear 5 drives the rotating column 4 to rotate synchronously with the placement plate 2 to complete the adjustment of the column angle, so that it is convenient to align the installation holes opened at the ends of the column and the beam during the installation process. After the beam and the column are installed and fixed, the driving plate 10 is pulled by the first electric push rod 8 to move in the direction away from the placement plate 2, and the cooperation of the guide groove 15 and the guide rod 16 will make the symmetrical clamping block 11 away from the position of the beam, thereby releasing the alignment. The crossbeam is clamped and fixed. After the driving plate 10 returns to the initial position, that is, the clamping block 11 returns to the initial position, the driving plate 10 will drive the placement table 9 away from the position of the placement plate 2 through the guide rod 16, so that the placement table 9 is reset. After the clamping block 11 is away from the crossbeam, under the action of elastic force, the push plate 19 and the rotating plate 20 return to the initial position, and the driven block 24, the fixed plate 25, the driven plate 26 and the connecting rod 13 are all moved up to the initial position. At this time, the limit block 36 and the limit slot 39 are separated, and the clamping block 11 can also rotate again. When the slot moves to above the clamping block 12 again, the clamping block 12 will limit and fix the placement table 9 again, and the limit on the column can be released by driving the clamping plate 3 away from the column by the second electric push rod 38.
