Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Embodiment 1 of the present invention: As Figures 1 - 10 shown, the present invention discloses a modular quick-installation connection structure for prefabricated mechanical and electrical pipe wells based on BIM, including a middle frame 1.

A connecting plate 14 is connected between the upper and lower sleeve frames 13; A card plate 18 is slidably connected to the connecting plate 14, and a card plate 2 19 is connected to one side of the card plate 18. Both ends of the card plate 18 and the card plate 2 19 are connected with an arc surface 20, and the card plate 18 and the card plate 2 19 are both slidably connected to the surface of the assembled pipe well 6. A positioning component is provided on the sleeve frame 13, and the positioning component is used to position the sleeve frame 13 on the crossbeam 10.

A driving component is also provided on the vertical beam 23, and the driving component is used to drive the support plate 28 to engage or separate with the support plate 7.

[0020] Among them, the assembled pipe well 6 and the electromechanical pipe 8 are the frame of the existing assembled pipe well and the pipes inside it, and the support frame plate 7 is centrally connected to the assembled pipe well 6. Its main function is to strengthen the structural strength of the assembled pipe well 6 while facilitating the support plate 28 to cooperate with it or support it, so as to realize the climbing of the middle frame 1 and the entire device.

[0021] The output end of each telescopic member 2 away from the middle frame 1 is connected to a connecting seat 3, and the side frames 4 are set in two left and right positions. Each side frame 4 is connected to the front and rear connecting seats 3 on its own side. In this way, through the connection of the connecting seat 3, the connection strength between the side frame 4 and the telescopic member 2 can be strengthened, the overall strength of the device is improved, and the reliability of the device during use is enhanced.

[0022] Pallet 18 is arranged parallel to the inner wall of the positioning frame 5 on one side of the side frame 4, and pallet 2 19 is arranged perpendicular to the inner wall of the positioning frame 5 on one side of the side frame 4, and pallet 18 and pallet 2 19 are connected perpendicularly to each other, and the length of pallet 2 19 is shorter than the length of pallet 18.

[0024] An operating port 9 is also provided on the side of the middle frame 1. The setting of the operating port 9 facilitates the connection of the butt ends after the upper and lower ends of the assembled pipe wells 6 are butt-jointed.

[0025] Embodiment 2 of the present invention: like Figures 1 - 10As shown in the figure, the present invention discloses a modular quick-install connection structure for prefabricated mechanical and electrical pipe shafts based on BIM. Compared with Embodiment 1, the structure of the positioning component is disclosed in this embodiment.

[0026] The positioning component includes a slideway groove 11, a limit slider 12, a bolt hole 21, and a bolt 22. The slideway groove 11 is opened in the cross beam 10 and penetrates through the left and right side surfaces of the cross beam 10. The limit slider 12 is slidably connected in the slideway groove 11, and the left and right ends of the limit slider 12 extend to the outside of the slideway groove 11 and are connected to the inner walls of both sides of the sleeve frame 13.

The bolt 22 is threadedly connected in the bolt hole 21, and one end of the bolt 22 abuts against the surface of the cross beam 10.

[0027] During specific use, it is possible to first measure the length, width, and height of each section of the installed prefabricated pipe shaft 6, and then slide the sleeve frames 13 on the front and rear sides of the cross beams 10, so that the distance between the second clamping plates 19 installed on the front and rear sleeve frames 13 through the connecting plate 14 is equal to the width of the prefabricated pipe shaft 6. At the same time, keep the sleeve frames 13 on the front and rear sides centered on the cross beam 10. After adjustment, rotate the bolt 22 so that the bolt 22 passes through the bolt hole 21 on the sleeve frame 13 and abuts against the surface of the cross beam 10, then the sleeve frame 13 can be positioned, ensuring that when hoisting and aligning the prefabricated pipe shaft 6, the sleeve frame 13 will not slide on the surface of the cross beam 10, causing errors.

[0028] Embodiment 3 of the present invention: As Figures 1 - 10 shown in the figure, the present invention discloses a modular quick-install connection structure for prefabricated mechanical and electrical pipe shafts based on BIM. Compared with Embodiment 2, the structure of the adjustment component is disclosed in this embodiment.

[0029] The adjustment component includes a lead screw 16. The lead screw 16 is threadedly sleeved in the connecting plate 14 and penetrates through the connecting plate 14. One end of the lead screw 16 close to the first clamping plate 18 is rotatably connected to the first clamping plate 18.

[0030] One side of the first clamping plate 18 is connected with a mounting plate 17. Both the upper and lower ends of the side of the mounting plate 17 close to the inner wall of the positioning frame 5 are connected with sliding rods 15. The sliding rods 15 penetrate and are slidably sleeved on the connecting plate 14. The lead screw 16 is rotatably connected to the mounting plate 17.

[0031] After adjusting the distance between the second clamping plates 19 on the front and rear sides, the lead screw 16 can be rotated to adjust the distance between the mounting plate 17 and the first clamping plate 18 and the inner wall of the positioning frame 5, so that the distance between the first clamping plates 18 on the left and right sides is equal to the length of the prefabricated pipe shaft 6 and is centered in the positioning frame 5. At the same time, the first clamping plate 18 can also be slidably sleeved on the connecting plate 14 through the sliding rods 15 to maintain stability during adjustment and sliding. In this way, when facing prefabricated pipe shafts 6 of different sizes, it can also be adapted through adjustment, improving the versatility.

[0032] Embodiment 4 of the present invention: As Figures 1 - 10 shown, the present invention discloses a modular quick-installation connection structure for prefabricated mechanical and electrical pipe shafts based on BIM. Compared with Embodiment 3, the structure of the driving component is disclosed in this embodiment.

[0033] The driving component includes a second telescopic member 25, which is installed on the vertical beam 23. There is a rotating plate 30 rotatably connected between the output end of the second telescopic member 25 and the supporting plate 28.

[0034] A sliding frame 26 is connected to the vertical beam 23. A sliding seat 27 is slidably sleeved on the sliding frame 26. The supporting plate 28 is connected to the sliding seat 27. Pin shaft seats 29 are installed on both the sliding seat 27 and the output end of the second telescopic member 25. Both ends of the rotating plate 30 are rotatably connected to the sliding seat 27 and the output end of the second telescopic member 25 through the pin shaft seats 29. An installation seat 24 is connected to the vertical beam 23, and the second telescopic member 25 is installed on the installation seat 24.

[0035] When installing the hoisted prefabricated pipe shaft 6 onto the prefabricated pipe shaft 6 below, the already installed prefabricated pipe shaft 6 is called the first pipe shaft, the hoisted prefabricated pipe shaft 6 to be aligned is called the second pipe shaft, and the un-hoisted prefabricated pipe shaft 6 is called the third pipe shaft. During specific installation, first measure the length, width, and height dimensions of the prefabricated pipe shaft 6, and then adjust the sleeve frame 13 and the lead screw 16 so that the distance between the first clamping plates 18 on the left and right sides is equal to the length of the prefabricated pipe shaft 6, and the distance between the second clamping plates 19 on the front and back sides is equal to the width of the prefabricated pipe shaft 6. Then hoist the middle frame 1 so that the first clamping plates 18 and the second clamping plates 19 in the lower positioning frame 5 of the middle frame 1 can smoothly snap onto the outside of the first pipe shaft through the arc surface 20. Then control the first telescopic members 2 on the upper and lower sides of the middle frame 1 to adjust so that the supporting plate 28 sliding on the vertical beam 23 of the lower positioning frame 5 can be exactly above the bearing support plate 7 of the first pipe shaft. Then extend the second telescopic member 25 to drive the supporting plate 28 to slide until the supporting plate 28 slides above the bearing support plate 7 and the lower end surface of the supporting plate 28 abuts against the upper end surface of the bearing support plate 7. Then hoist the second pipe shaft and make the second pipe shaft slide along the first clamping plates 18 and the second clamping plates 19 in the upper positioning frame 5 of the middle frame 1, and the efficient direct alignment of the first pipe shaft and the second pipe shaft can be realized. And because the first telescopic members 2 on the upper and lower sides are adjusted synchronously, at this time, the middle frame 1 is centered at the connection of the mutually approaching ends of the first pipe shaft and the second pipe shaft. Then the first pipe shaft and the second pipe shaft can be connected through the operation port 9; After the connection between the first pipe well and the second pipe well is completed, drive each of the first telescopic members 2 to extend synchronously again, so that the upper positioning frame 5 moves to the position of the bearing bracket plate 7 of the third pipe well to be hoisted. Then, perform the same hoisting and installation on the third pipe well. After the installation of the third pipe well is completed, control the sliding of the support plate 28 in the positioning frame 5 on the upper side of the middle frame 1 until the lower end thereof abuts against the upper side of the bearing bracket plate 7 of the third pipe well. Then, cancel the support of the support plate 28 in the positioning frame 5 on the lower side of the middle frame 1 and the bearing bracket plate 7 of the first pipe well, and control each of the first telescopic members 2 to contract synchronously until the lower positioning frame 5 is fixed to the position corresponding to the bearing bracket plate 7 of the second pipe well, and control the support plate 28 in the lower positioning frame 5 to abut against the upper side of the bearing bracket plate 7 of the second pipe well. Subsequently, control each of the first telescopic members 2 to extend synchronously, and the external force hoisting of the middle frame 1 can be realized, and the climbing can be achieved, which improves the efficiency of continuous alignment and installation of the assembled pipe well 6 and realizes high-precision rapid continuous installation.
