[0003] After the steel cage is hoisted into the outer mold and positioned accurately, the two end molds are closed, and then the columns and roller joists required for the inner mold to move are hoisted to the beam ends and manually moved to the corresponding positions. There are mostly but not limited to 8 joists and 16 columns, each column weighs about 30 kilograms, and each joist weighs about 160 kilograms. Since the steel cage is a horizontal cylinder structure, the hoisting equipment in the inner mold cannot be used. Each time the columns and joists are moved, they are manually moved. There are also nylon wheels under the joists, and the steel cage is manually grooved with rail grooves and dragged in. In addition, each time, the column locking bolts must be tightened at the bottom of the bottom mold, and then the longitudinal connecting rods of the joists are moved in and longitudinally connected to the end mold fixing seat to enhance the overall stability of the inner mold walking joists.

The inner mold bracket comprises a main longitudinal beam 6, a foldable walking guide beam 7, a guide beam adjustment device 8, a slidable cross beam 9, a CNC lifting column 10, a CNC column lifting device 11, a longitudinal and cross beam sliding connection device 12 and an inner mold walking roller 13. The guide beam adjustment device 8 drives the foldable walking guide beam 7 to move the ... The beam 7 is colinear or upwardly warped with the main longitudinal beam 6, and the main longitudinal beam 6 is arranged above the travel drive device 14. The guide beam adjustment device 8 is connected to the foldable travel guide beam 7, and the foldable travel guide beam 7 is hinged to the end of the main longitudinal beam 6. The slidable crossbeam 9 is slidably connected to the main longitudinal beam 6 through the longitudinal and transverse beam sliding connection device 12, and the longitudinal and transverse beam sliding connection device 12 includes a sliding drive device 16 for the slidable crossbeam 8 to move relatively on the main longitudinal beam 6. The CNC column lifting device 11 is located on the inner side of the longitudinal and transverse beam sliding connection device 12 and is arranged at both ends of the slidable crossbeam 9. The CNC column lifting device 11 drives and connects the CNC lifting column 10, and the inner mold travel supporting wheel 13 is arranged on the surface of the slidable crossbeam 9.

[0026] The guide beam adjustment device 8 drives the foldable walking guide beam 7 to be in line with or upward with the main longitudinal beam 6. In the walking state, the main longitudinal beam 6 and the foldable walking guide beam 7 are in line. After installation, the guide beam adjustment device 8 will tilt the foldable walking guide beam 7 upward, and the main longitudinal beam 6 will fall to the use elevation position with the slidable cross beam 9 without interfering with the steel cage 1 and the end template 4. The main longitudinal beam 6 is provided with a detection sensor for detecting the position status of the slidable cross beam 9. The cross-sectional size of the CNC lifting column 10 matches the aperture size of the bottom mold column sleeve 5. An automatic column locking device is provided inside the bottom mold column sleeve 5. The walking drive device 14 is provided with a plurality of groups, and support rollers 15 are provided between adjacent walking drive devices 14.

[0027] The bottom mold column sleeve 5 on the bottom mold plate 2 is designed according to the drainage hole of the precast beam, and a PVC drainage pipe with an inner diameter larger than the cross-sectional area of ​​the CNC lifting column 10 is arranged at the corresponding position on the steel cage 1. The design of the bottom mold column sleeve 5 can avoid the traditional work of drilling the bottom and fixing the column with bolts, and realize automatic and stable insertion.

[0028] The main longitudinal beam 6 is the mechanism for the overall movement of the inner mold bracket. It can slide relative to the slidable cross beam 9 through the longitudinal and cross beam sliding connection device 12. The CNC column lifting device 11 can drive the CNC lifting column 10 to lift or lower as needed.

[0029] In specific implementation, the present invention also includes a PLC or touch screen embedded control system. According to different prefabricated beam types, the position of the slidable beam 9 in use status can be input and memorized, the installation distance between the walking drive device 14 and the end of the bottom template 2 can be input, and the distance between each row of bottom mold column sleeves 5 and the driving point can be calculated. Then, according to the current position of the slidable beam 9 on the main longitudinal beam 6, the stacked CNC lifting column 10 is inserted into the bottom mold column sleeve 5 according to the programming.

[0030] The process of the inner mold bracket automatically sliding in is as follows:

[0031] 1. The foldable walking guide beam 7 is automatically adjusted to the end portion being flush with the bottom surface of the middle portion through the guide beam adjustment device 8;

[0032] 2. All the slidable cross beams 9 are stacked to the front end of the main longitudinal beam 6, and all the CNC lifting columns 10 are automatically retracted to a bottom not lower than the bottom of the main longitudinal beam 6;

[0033] 3. Turn on the travel drive device 14 to make the inner mold bracket gradually slide toward the pouring position where the steel cage 1, the end mold plate 4, etc. have been installed and positioned;

[0034] 4. When the last slidable beam 9 of the stack is moved and measured and approaches the first row of bottom mold column sleeves 5, the last slidable beam 9 is driven to decelerate and step to control the last slidable beam 9 to align with the first row of bottom mold column sleeves 5;

[0035] 5. The CNC lifting column 10 on the last slidable crossbeam 9 is CNC-inserted into the bottom mold column sleeve 5, and the bottom mold column sleeve 5 automatically locks the CNC lifting column 10;

[0036] 6. The walking drive continues, and when the second slidable crossbeam 9 approaches the second row of bottom mold column sleeves 5, the operations described in 4 and 5 above are performed;

[0037] 7. This is repeated until all the slidable beams 9 automatically insert the CNC lifting columns 10 into the corresponding bottom mold column sleeves 5 and lock them;

[0038] 8. The guide beam adjustment device 8 works to tilt the end of the foldable walking guide beam 7 to make room for the entire inner mold bracket to fall;

[0039] 9. Use the CNC column lifting device 11 to lower the inner mold bracket system as a whole to the use elevation.

[0040] The process of the inner mold bracket automatically sliding out is as follows:

[0041] 1. The inner mold bracket is raised as a whole by the numerically controlled column lifting device 11 until the main longitudinal beam 6 and the foldable walking guide beam 7 are straightened and do not interfere with the steel cage 1 and the end mold plate 4;

[0042] 2. The guide beam adjustment device 7 makes the main longitudinal beam 6 and the foldable walking guide beam 7 collinear and straight;

[0043] 3. The last inserted CNC lifting column 10 is lifted from the last row of bottom mold column sleeves 5 by the CNC column lifting device 11 until the lower surface of the CNC lifting column 10 is flush with the lower surface of the main longitudinal beam 6;

[0044] 4. The travel drive device 14 starts in the reverse direction, driving the inner mold bracket to slide outward from the beam. When the raised CNC lifting column 11 approaches the adjacent CNC lifting column 11, the travel drive device 14 slows down and stops, and the second row of CNC lifting columns 10 are lifted from the bottom mold column sleeve 5 until the lower surface of the CNC lifting column 10 is flush with the lower surface of the main longitudinal beam 6;

[0045] 5. Repeat this process until the inner mold bracket slides out of the beam safely;

[0046] 6. The travel drive device 14 continues to reversely drive the inner mold bracket away from the working area until it does not affect the travel of the beam lifting machine.

[0047] Each set of automatic integral inner mold bracket can simultaneously serve two colinear work areas in the longitudinal direction.

[0048] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
