DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides three technical solutions, including the following embodiments:

[0028] Example 1

[0029] See also Figure 1-Figure 2 A transport device for assembled building prefabricated parts, comprising a lifting platform 1, which can be raised and lowered to provide a stable and suitable placement support platform for assembled building prefabricated parts, and a four-way vertical flip mechanism 2 is arranged on the top of the lifting platform 1 to drive the prefabricated parts to flip around for unloading;

[0030] The four-way vertical flip mechanism 2 includes a square frame 21 fixed on the top of the lifting platform 1. The square frame 21 is made of high-strength steel and has a high load-bearing capacity and structural stability. A mounting seat 22 is arranged in the center of the square frame 21. Figure 2A U-shaped frame 23 is provided on the mounting seat 22, and the U-shaped frame 23 is rotatably connected to the mounting seat 22 through a universal joint 24. The universal joint 24 is a high-precision professional component that can be flexibly rotated at multiple angles. The universal joint 24 can be flexibly rotated at multiple angles. A motor 25 is fixed on one side of the U-shaped frame 23. The motor 25 is controlled by an external switch and is electrically connected to the mobile power supply carried on the lifting platform 1. The motor 25 drives the universal joint 24 to rotate. When the motor 25 rotates, it drives the rotating arm 1 27 and the rotating arm 28 to support and rise. At the same time, the universal joint 24 controls the steering of the rotating arm 1 27 and the rotating arm 28. A flip plate 26 is provided above the square frame 21. A rotating arm 27 is fixed on one side of the U-shaped frame 23. One end of the rotating arm 27 is rotatably connected to the rotating arm 28 through a pin shaft, and one end of the rotating arm 28 is connected to the flip plate through a universal joint 29. 26 is rotatably connected at the bottom, four fixed seats 210 are fixed on the top of the square frame 21, and placement grooves 211 are opened on the tops of the four fixed seats 210. An L-shaped seat 212 is fixed on one side of the fixed seat 210, and a cylinder 213 is fixed on the L-shaped seat 212. The cylinder 213 is controlled by an external switch and is electrically connected to an external power supply. An L-shaped plate 214 is fixed on the output end of the cylinder 213, and one side of the L-shaped plate 214 passes through the L-shaped seat 212 and extends to the outside thereof. Four limiting columns 215 are fixed at the bottom of the flip plate 26, and the four limiting columns 215 are all placed in the placement grooves 211. The limiting columns 215 are adapted to the size of the placement grooves 211. After the cylinder 213 pushes the L-shaped plate 214 to lock the limiting columns 215, the limiting columns 215 can rotate in the placement grooves 211, and the limiting columns 215 drive the flip plate 26 to vertically flip and unload.

[0031] By setting up the four-way vertical flipping mechanism 2, precise control of the four-way vertical flipping unloading of the prefabricated parts in front, behind, left and right directions is achieved, which greatly meets the unloading needs in different directions. When unloading operations are carried out in some narrow building spaces, there is no need to frequently move the transfer device to adjust the unloading position. Only relying on its own flipping function, the unloading operation can be completed quickly, accurately and efficiently, thereby greatly improving the overall unloading efficiency and providing a strong guarantee for the construction process of prefabricated buildings.

[0032] Two bottom plates 5 are fixed to the bottom of the two side frames 41. The material of the bottom plates 5 is strong and durable, and can bear the weight of the entire transfer device and the load of the prefabricated parts. Universal wheels 6 are set at the bottom of the two bottom plates 5. The universal wheels 6 are made of high-quality wear-resistant, silent and flexible products, which can easily control the entire transfer device to move quickly and flexibly, making it convenient to shuttle through the complex terrain of the construction site. An ergonomically designed handlebar 7 is fixed to the top of one of the bottom plates 5. The operator can easily push or pull the transfer device by holding the handlebar 7 to achieve convenient transfer of prefabricated parts.

[0033] Example 2

[0034] Based on Example 1, see Figure 3-Figure 4 As shown, a stacking and layer-by-layer unloading component 3 for controlling the stacking of preforms and unloading them layer by layer is provided on the top of the flip plate 26. The stacking and layer-by-layer unloading component 3 includes four support rods 31 fixed on the top of the flip plate 26, a cross plate 32 is fixed between the top ends of the four support rods 31, and four columns 33 are fixed on the top of the cross plate 32.

[0035] A plurality of pulleys 34 are rotatably connected to the four columns 33, and two pulleys 34 are connected laterally by a belt 35. The tension of the belt 35 is moderate to ensure that there is no slipping or loosening during the transmission process. An L-shaped support plate 36 is fixed on the top of the pulley 34, and the prefabricated parts are placed on the L-shaped support plate 36. A connecting plate 37 is also fixed on the top of the pulley 34, and L-shaped vertical plates 38 are fixed on both sides of the horizontal plate 32.

[0036] One side of the two L-shaped vertical plates 38 is rotatably connected to a plurality of electric push rods 39 via a rotating shaft. The electric push rods 39 are controlled by an external switch and electrically connected to an external power supply. The output ends of the plurality of electric push rods 39 are rotatably connected to one side of the connecting plate 37. Specifically, a slide groove is provided on one side of the connecting plate 37, and a moving block slides inside the slide groove. The output end of the electric push rod 39 is rotatably connected to one side of the moving block via a pin shaft. Two limit plates 310 are fixed to the top of the cross plate 32. The setting of the limit plates 310 can limit the two sides of the prefabricated parts to prevent the prefabricated parts from sliding out from both sides during the flipping process.

[0037] By setting up the stacking layer-by-layer unloading component 3, the preforms are stacked on the L-shaped pallet 36, and then the L-shaped pallet 36 is opened layer by layer, and the four-way vertical flipping mechanism 2 is cooperated to flip and unload the preforms, and the single preforms are unloaded layer by layer, so that the unloading position of each preform can be controlled.

[0038] Example 3

[0039] Based on Example 2, see Figure 5-Figure 6 As shown, an automatic lifting component 4 is arranged below the lifting platform 1 to drive the lifting platform 1 to move up and down. The automatic lifting component 4 includes two side frames 41 arranged below the lifting platform 1, and a rotating rod 42 is fixedly connected between the opposite sides of the two side frames 41 and between the inner walls of the bottom of the lifting platform 1.

[0040] Two lifting arms 43 are rotatably connected to the two rotating rods 42, two sliders 44 are slidably connected between the opposite sides of the two side frames 41 and the inner wall of the bottom of the lifting platform 1, a rotating rod 45 is fixed between the opposite sides of the two sliders 44, and a lifting arm 46 is rotatably connected to the two rotating rods 45.

[0041] The two lifting arms 1 43 and the lifting arm 2 46 are rotatably connected via a connecting shaft 47. A connecting seat 48 is fixed between the two rotating arms 1 27. An electric push rod 2 49 is rotatably connected to the connecting seat 48 via a pin shaft. The electric push rod 2 49 is controlled by an external switch and electrically connected to an external power supply. A steering seat 410 is rotatably connected to the rotating rod 2 45. The output end of the electric push rod 2 49 is fixed to one side of the steering seat 410. After the electric push rod 2 49 is started, it can drive the lifting arm 1 43 to rotate and lift, so that the slider 44 slides in the side frame 41. When the lifting arm 1 43 rotates, it drives the lifting arm 2 46 to rotate.

[0042] By setting the automatic lifting component 4, the free lifting of the lifting platform 1 is realized, and then the height of the prefabricated parts is controlled to be adjusted, which satisfies the unloading operation of the prefabricated parts at different heights, and the degree of automation is high.

[0043] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] During operation, the prefabricated parts are placed on four L-shaped pallets 36 for stacking, and then the handlebar 7 is pulled to drive the prefabricated parts for transportation. When the prefabricated parts are transported to the unloading position, the cylinder 213 in the direction in which the prefabricated parts need to be unloaded is activated. After the cylinder 213 is activated, the cylinder 213 pushes the L-shaped plate 214, and the L-shaped plate 214 locks the corresponding limiting column 215 in the placement groove 211, and then the motor 1 25 is started, so that the motor 1 25 drives the rotating arm 1 27 and the rotating arm 28 to rotate and rise, and then drives the flip plate 26 to flip around the limiting column 215 locked in the placement groove 211, and then drives the prefabricated parts to be transported to the unloading position. The parts are flipped to a vertical state for unloading, and the electric push rod 39 is started to shrink, and the electric push rod 39 drives the connecting plate 37 and the pulley 34 to rotate, and the pulley 34 drives the L-shaped support plate 36 to rotate counterclockwise, thereby driving the L-shaped support plate 36 to open, so that the prefabricated parts of the next layer can be flipped and unloaded. The above operation is repeated to unload the prefabricated parts of each layer in turn, and the electric push rod 49 is started to drive the lifting arm 43 to rise and fall, thereby controlling the height of the lifting platform 1, and then driving the prefabricated parts to rise and fall, thereby satisfying the unloading operation at different heights.

[0045] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
