[0035] Furthermore, in order to facilitate the assembly of the box girder inner mold assembly, the lateral displacement mechanism includes a horizontal displacement guide rail 6 installed above the mounting base 1, which guides and limits the movement direction of the lateral displacement mechanism. A displacement motor 61 is installed on the left surface of the horizontal displacement guide rail 6 through bolts. The displacement motor 61 converts electrical energy into mechanical energy, thereby achieving the effect of providing a power source for the lateral displacement mechanism. A displacement rod 62 is fixedly installed on the output shaft of the displacement motor 61 through a coupling. One end of the displacement rod 62 is fixedly positioned at the axis of the horizontal displacement guide rail 6 through a bearing and extends to the right side surface of the horizontal displacement guide rail 6. The surface of the displacement rod 62 is bounded by the center and is provided with left-handed threads and right-handed threads at both ends, respectively.

[0036] The outer surface of the left-handed thread is threadedly sleeved with a left-handed displacement block 63, whose outer surface is slidably sleeved with the inner wall of the guide groove of the horizontal displacement guide rail 6. The outer surface of the right-handed thread is threadedly sleeved with a right-handed displacement block 64, whose outer surface is slidably sleeved with the inner wall of the guide groove of the horizontal displacement guide rail 6. After the displacement motor 61 drives the displacement rod 62 to rotate in the horizontal displacement guide rail 6, it drives the left-handed displacement block 63 and the right-handed displacement block 64 at both ends of the horizontal displacement guide rail 6 to achieve the expansion and closing actions along the left-handed thread and the right-handed thread trajectories on the surfaces of the two ends of the horizontal displacement guide rail 6.

One end of the piston rod of the bottom arc cylinder 77 is hinged to the upper surface of the lower base plate 4 through a pin. The bottom arc cylinder 77 telescopes and drives the lower base plate 4 to rotate in an arc with the axis of the pin located below the side panel 3 as the center of the circle, thereby adjusting the installation angle of the lower base plate 4.

[0042] Furthermore, in order to provide a power source to the swing mechanism, the swing mechanism includes a servo motor 8 symmetrically installed on the inner top wall of the side panel 3 through a motor mounting seat. The servo motor 8 is provided to provide a power source to the swing mechanism. The output shaft of the servo motor 8 is fixedly installed with a transmission shaft 81 through a coupling. One end of the transmission shaft 81 is fixedly sleeved with a winding wheel 82 with a steel wire rope wrapped around the outer surface. After the servo motor 8 drives the transmission shaft 81 to rotate, it drives the winding wheel 82 to wind and release the steel wire rope. A symmetrically distributed mounting frame 83 is fixedly installed on the inner top wall of the side panel 3.

[0043] Furthermore, in order to guide the movement direction of the wire rope, a rotating shaft 84 is installed at equal intervals on the front of the mounting frame 83 through bearings, and the outer surfaces of the two rotating shafts 84 located in the mounting frame 83 are fixedly sleeved with a first wire pulley 85, which guides and limits the movement direction of the wire rope.

A controller 811 for controlling the operation of the lateral displacement mechanism, the angle adjustment mechanism and the swing mechanism is fixedly installed on the front of the mounting base 1. After the servo motor 8 drives the transmission shaft 81 and the winding wheel 82 connected to one end of the transmission shaft 81 to rotate, the wire rope wrapped around the surface of the winding wheel 82 is driven to achieve a winding action, and the upper top plate 2 is driven to achieve a swinging action with the axis of the rotating rod 86 as the center of the circle.

[0046] By setting up a lateral displacement mechanism, an angle adjustment mechanism and a swing mechanism, it is possible to adjust the angles of the upper top plate 2, the side plate 3 and the lower bottom plate 4 of the box girder inner formwork assembly according to actual construction needs, which not only improves the construction efficiency of the box girder inner formwork, but also reduces the input of construction personnel, gradually transforming from traditional manual work to intelligent and mechanized work, creating an industrialized intelligent beam yard.

[0047] Working principle: Step 1, adjusting the installation angle of the upper top plate 2, specifically: the controller 811 controls the servo motor 8 to start, drives the transmission shaft 81 and the winding wheel 82 connected to one end of the transmission shaft 81 to rotate, and drives the wire rope wound on the surface of the winding wheel 82 to achieve the winding action, and then the upper top plate 2 rotates clockwise with the axis of the rotating rod 86 as the center of the circle, thereby adjusting the installation angle of the upper top plate 2;

[0048] Step 2, adjusting the inclination angle of the side panel 3, specifically: the controller 811 controls the adjustment motor 7 to start, and drives the worm 71 to mesh with the worm wheel groove 73 located on the outer arc surface of the angle adjustment arc plate 72, and then drives the gear groove 74 located on the inner arc surface of the angle adjustment arc plate 72 to mesh with the gear 76, and drives the side panel 3 to rotate upward or downward with the axis of the adjustment rod 75 as the center of the circle, thereby adjusting the inclination angle of the side panel 3;

[0049] Step 3, adjusting the installation angle of the lower base plate 4, specifically: the controller 811 controls the bottom arc cylinder 77 to extend and retract, driving the lower base plate 4 to rotate in an arc with the axis of the pin shaft located below the side plate 3 as the center of the circle, thereby adjusting the installation angle of the lower base plate 4;

[0050] Step 4: According to the actual construction needs, through the above steps 1 to 3, the installation angle of the upper top plate 2, the inclination angle of the side plate 3 and the installation angle of the lower bottom plate 4 are adjusted to the actual required angles, and then the box beam inner mold assembly is assembled;

[0051] Step 5: Control the arc-shaped laminating cylinder 66 and the displacement motor 61 to start, and the arc-shaped laminating cylinder 66 drives the laminating plate 65 to swing in an arc shape with the axis of the pin as the center of the circle, so that the installation angle of the laminating plate 65 is consistent with the inclination angle of the side plate 3, so as to facilitate better laminating of the laminating plate 65 and the side plate 3;

[0052] After the displacement motor 61 drives the displacement rod 62 to rotate in the horizontal displacement guide rail 6, it drives the left-handed displacement block 63 and the right-handed displacement block 64 at both ends of the horizontal displacement guide rail 6 to realize the expansion and closing actions along the left-handed thread and the right-handed thread trajectory on the surfaces of the two ends of the horizontal displacement guide rail 6. When driving the bonding plate 65 to contact the side plate 3, the control electromagnet 67 is energized and started to achieve the effect of suction and auxiliary fixation of the side plate 3. After the suction is completed, the displacement motor 61 drives the box beam inner mold assembly to realize the assembly action through the left-handed displacement block 63 and the right-handed displacement block 64, and drives the guide sleeve 5 to slide in the guide groove of the mounting base 1.
