Description

Technical Field

[0001] This utility model relates to the field of building formwork processing machinery, specifically to a mobile stacking and destacking machine for prefabrication mold tables. Background Technology

[0002] Precast components are concrete components that are prefabricated in a factory or on-site according to design requirements, and the formwork is the core carrier of the concrete component. After pouring, the formwork needs a certain period of curing before it can be demolded. Laying these formworks flat would take up a lot of limited factory space. Therefore, stacking the formworks at intervals for curing is a common method nowadays.

[0003] Because the formwork itself is quite heavy, plus the poured concrete and embedded steel bars, the overall weight is very large. Conventional hoisting equipment (such as overhead cranes) cannot achieve stable hoisting, which can easily cause tilting, making the freshly poured concrete sway inside the formwork and resulting in quality defects in the precast components. Utility Model Content

Detailed Implementation

[0023] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0024] like Figures 1-6 As shown, a mobile stacker / destacking machine for a prefabrication platform includes a U-shaped frame 12 and a moving device disposed below the U-shaped frame 12.

[0025] The mobile device includes a first column 1, a second column 2, a third column 3, and a fourth column 4. A first connecting rod 5 is provided between the first column 1 and the second column 2, fixing the first column and the second column together. A second connecting rod 6 is provided between the third column 3 and the fourth column 4, fixing the third column and the fourth column together. The two ends of the first connecting rod 5 and the second connecting rod 6 are connected by vertical third connecting rods 7 and 8, respectively. The first connecting rod and the second connecting rod are parallel to each other, with one end of the first connecting rod connected to one end of the second connecting rod via the third connecting rod, and the other end of the first connecting rod connected to the other end of the second connecting rod via the fourth connecting rod. Thus, the main frame structure of the mobile device is formed.

[0026] Two telescopic rods 9 are provided at the bottom of both the first connecting rod 5 and the second connecting rod 6, and each telescopic rod 9 has a track wheel 10 at its bottom. Telescopic rods of varying lengths are provided at both ends of the bottom of the first and second connecting rods. These telescopic rods can be either electric or hydraulic cylinders. Track wheels are rotatably connected to the bottom of the telescopic rods, and these track wheels are driven by a motor 20. When the telescopic rods extend, the track wheels contact the ground, lifting the main frame of the mobile device off the ground. At this time, the track wheels rotate under the drive of the motor, realizing the overall movement of the mobile device.

[0027] The tops of the first column 1, the second column 2, the third column 3, and the fourth column 4 are fixedly connected to the bottom of the H-shaped frame 12 via hydraulic cylinders 11. Preferably, the four corners of the H-shaped frame are connected to the four columns via hydraulic cylinders. Concrete formwork or a formwork platform is placed on the H-shaped frame, and the four columns lift the H-shaped frame and the formwork platform via hydraulic cylinders, enabling the stacking and disassembly of the formwork platform. To accommodate heavier formwork platforms, two more sets of columns can be added in the middle of the H-shaped frame. These columns are fixed to the third and fourth connecting rods via connecting rods. In this way, the six sets of hydraulic cylinders work together to ensure stability during lifting and lowering.

[0028] Gear devices are provided at the two outer ends of the third connecting rod 7 and the fourth connecting rod 8, the inner sides of the first column 1 and the fourth column 4, and the inner sides of the second column 2 and the third column 3. Preferably, gear devices are provided at one end of the third connecting rod and the first column, and at the other end of the third connecting rod and the fourth column, respectively, from two directions. A positioning rod 14 is provided at each corner, and the same positioning rod is equipped with racks in two directions to achieve the positioning function. Similarly, gear devices are provided at one end of the fourth connecting rod and the second column, and at the other end of the fourth connecting rod and the third column, respectively, from two directions. Finally, gears are provided at each of the four corners from two directions, and positioning rods are provided at the four positions at the bottom of the H-shaped frame 12, respectively.

[0029] The two gear devices on the third connecting rod 7, the two gear devices on the fourth connecting rod 8, the two gear devices on the first column 1 and the second column 2, and the two gear devices on the third column 3 and the fourth column 4 are coaxially connected by the connecting shaft 13. This makes all the gear devices and rack structures form a whole. When a certain cylinder on the column cannot work properly, the smooth lifting and lowering of the H-shaped frame can still be achieved by cooperating with other cylinders and gear racks.

[0030] The gear assembly includes a fixed plate 16, bearing seats 17 disposed on both sides of the fixed plate 16, and a gear shaft 18 passing between the two bearing seats. A gear 19, rotating with the gear shaft 18, is disposed between the two bearing seats 17. Racks on the four positioning rods mesh with the gears in the gear assembly. Position sensors 21 are installed on both the first connecting rod 5 and the second connecting rod 6. These position sensors allow for precise control of the moving device's position, ensuring accurate positioning and enabling precise stacking and dismantling of the mold. Combined with the PLC controller for the joint control of the cylinders, motors, and telescopic rods, automated operation can be achieved.
