DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 , an embodiment provided by the utility model:

[0024] A construction template assembly limit frame: comprising a base frame 1, a universal wheel 11 is arranged at the bottom of the base frame 1, a cross bar 2 is fixedly connected to the surface of the base frame 1, a first motor 21 is fixedly connected to the surface of the cross bar 2, a first bidirectional screw rod 22 is fixedly connected to the output shaft of the first motor 21, the first motor 21 drives the first bidirectional screw rod 22 to rotate through the output shaft, a vertical rod 23 is threadedly connected to the surface of the first bidirectional screw rod 22, a second motor 24 is fixedly connected to the top of the vertical rod 23, a second bidirectional screw rod 25 is fixedly connected to the output shaft of the second motor 24, and the second motor 24 drives the second bidirectional screw rod 25 through the output shaft. The screw rod 25 rotates, and a square nut 26 is threadedly connected on the surface of the second bidirectional screw rod 25. A connecting plate 27 is fixedly connected to the surface of the square nut 26. A supporting cylinder 28 is fixedly connected to the surface of the connecting plate 27. A supporting plate 29 is fixedly connected to the piston rod of the supporting cylinder 28. One side of the building formwork requires a limit frame for limit support. The limit frame supports one side of the building formwork through four groups of support plates 29. By controlling the positions of the four groups of support plates 29 on the building formwork, the support plates 29 can support building formworks of different sizes, thereby improving the flexibility of the limit frame.

[0025] Furthermore, a docking mechanism is provided on the surface of the base frame 1, and the docking mechanism includes a docking rod 3, which is rotatably connected to the surface of the base frame 1, and a first bolt 31 is fixedly connected to the surface of the docking rod 3, and a docking block 32 is perforated on the surface of the first bolt 31, and a second bolt 33 is threadedly connected to the surface of the docking block 32, and a limiting nut 34 is threadedly connected to the surface of the second bolt 33. The docking mechanism can fix two sets of limit frames together. When a building formwork needs to be supported on both sides, the docking mechanism can be used to complete the expansion of the function of the limit frame.

[0026] Furthermore, a threaded hole is provided at the bottom of the vertical rod 23, and the first bidirectional screw rod 22 is threadedly connected to the threaded hole of the vertical rod 23. A guide groove is provided on the surface of the first motor 21. The first bidirectional screw rod 22 rotates on the guide groove of the first motor 21, and the first bidirectional screw rod 22 drives the vertical rod 23 to slide on the surface of the first motor 21. Two groups of vertical rods 23 are provided, and the moving directions of the two groups of vertical rods 23 are opposite. During the movement of the vertical rod 23, the supporting cylinder 28 and the supporting plate 29 will be driven to move horizontally through the connecting plate 27, thereby supporting the horizontal position of the support plate 29 relative to the building formwork.

[0027] Furthermore, the vertical rod 23 and the first motor 21 are perpendicular to each other, and a guide groove is opened on the surface of the vertical rod 23. The second bidirectional screw rod 25 rotates on the guide groove of the vertical rod 23, and the second bidirectional screw rod 25 drives the square nut 26 to slide on the surface of the vertical rod 23. There are two groups of square nuts 26, and the moving directions of the two groups of square nuts 26 are opposite. During the lifting process, the square nut 26 changes the horizontal height of the support cylinder 28 and the support plate 29 through the connecting plate 27, thereby changing the limit position of the support plate 29 on the building formwork.

[0028] Furthermore, the support cylinder 28 and the support plate 29 are synchronously raised and lowered following the square nut 26 through the connecting plate 27. The support cylinder 28 and the vertical rod 23 are always kept vertical. The support plate 29 moves on the vertical rod 23 through the piston rod of the support cylinder 28. The support plate 29 contacts the building formwork during the movement. The four groups of support plates 29 support and limit the building formwork on the vertical rod 23, thereby meeting the assembly requirements of the building formwork.

[0029] Furthermore, all circular holes are opened on the surface of the base frame 1, and threaded holes are opened on the surface of the docking rod 3. The limit nut 34 is threadedly connected to the threaded hole of the docking rod 3. The limit nut 34 limits the rotation of the docking rod 3 on the base frame 1 through the circular hole of the base frame 1. The limit nut 34 limits the docking rod 3 to the side of the base frame 1, so that the docking rod 3 is folded on the surface of the base frame 1, saving the space occupied by the docking rod 3.

[0030] Furthermore, a circular hole is opened on the surface of the first bolt 31, and the docking block 32 passes through the circular hole of the first bolt 31. The docking block 32 and the second bolt 33 can fix the two groups of first bolts 31 together. The docking block 32 and the second bolt 33 connect the two groups of docking rods 3 together through the first bolt 31, and then the two groups of limit frames are docked together through the docking rod 3.

[0031] Working principle: the first bidirectional screw rod 22 is driven to rotate by the output shaft of the first motor 21, and the first bidirectional screw rod 22 drives the two groups of vertical rods 23 to move in opposite directions on the first motor 21. During the movement of the vertical rod 23, the supporting cylinder 28 and the supporting plate 29 are driven to move horizontally through the connecting plate 27, so that the horizontal position of the supporting plate 29 relative to the building template is adjusted. The second bidirectional screw rod 25 is driven to rotate by the output shaft of the second motor 24, and the second bidirectional screw rod 25 drives the two groups of square nuts 26 to slide and rise and fall in opposite directions on the vertical rod 23. During the lifting process, the square nut 26 changes the horizontal height of the supporting cylinder 28 and the supporting plate 29 through the connecting plate 27, thereby changing the limit position of the supporting plate 29 on the building template again. The supporting cylinder 28 then uses the piston rod to make the supporting plate 29 support the building template. By changing the supporting position of the supporting plate 29 on the building template, building templates of different sizes can be supported.

[0032] The limiting nut 34 is rotated on the threaded hole of the docking rod 3, and the limiting nut 34 is removed from the circular hole of the base frame 1, and the restriction of the limiting nut 34 on the docking rod 3 is cancelled. The docking rod 3 can now rotate on the base frame 1, and the docking rod 3 drives the first bolt 31 to rotate, and the position of the first bolt 31 is adjusted, and the first bolts 31 of the two groups of limiting frames are contacted and connected together, and then the docking block 32 passes through the circular holes of the two groups of first bolts 31 at the same time, and the second bolt 33 cooperates with the docking block 32 to fix the two groups of first bolts 31 together. The first bolt 31 docks the two groups of limiting frames together through the docking rod 3. When a building template needs to be supported on both sides, the limiting frame is functionally expanded through the docking mechanism.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
