[0047] Embodiment 2:

[0048] The difference between the above embodiment and this embodiment is that: Figure 5 and Figure 6 As shown, the connecting rod 203 is L-shaped, and a limit seat 2031 is slidably provided on the connecting rod 203. The bottom of the limit seat 2031 is installed on the base plate 101. A guide plate 2023 is installed at the end of the connecting rod 203.

The turntable 201 rotates counterclockwise (in Figure 5As a reference, the position of the cam slot 202 on the turntable 201 changes synchronously, and a guide slider 2021 is engaged with the cam slot 202. At this time, the guide slider 2021, the guide rod 2022, the guide plate 2023, and the connecting rod 203 can only slide horizontally under the limit of the limit seat 2031, and the cam slot 202 can drive the guide rod 2022 and the connecting rod 203 to reciprocate horizontally.

A baffle 2043 is installed on the side wall of the lifting plate 2042, and both ends of the baffle 2043 are connected to the side wall of the mounting seat 2063. The flap 205 can rotate on the positioning shaft 2051, and the first torsion spring 2052 on the positioning shaft 2051 is used to facilitate later resetting. When the flap 205 rotates to an inclined state, the workpiece on the flap 205 can automatically slide onto the lifting platform 1031, thereby achieving the purpose of automatic unloading.

[0050] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, further, a limiting rod 2044 is movably provided on the side wall of the lifting plate 2042, a limiting plate 2045 is installed on the top of the limiting rod 2044, the diameter of the limiting plate 2045 is larger than the diameter of the limiting rod 2044, a limiting spring 2046 is sleeved on the limiting rod 2044, one end of the limiting spring 2046 is clamped on the lifting plate 2042, and the other end is clamped on the bottom of the limiting plate 2045, a limiting slider 2047 is installed on the bottom of the limiting rod 2044, and the limiting slider 2047 is slidably set on the limiting slide groove 2048 opened at the bottom of the base plate 101. When the lifting plate 2042 swings, the lifting plate 2042 slides on the limit rod 2044, and the limit slider 2047 at the bottom of the limit rod 2044 slides on the limit slide groove 2048.

[0051] Embodiment 3:

[0052] The difference between the above embodiment and this embodiment is that: Figure 6 and Figure 7 As shown, a transmission shaft 2062 is rotatably installed inside the mounting seat 2063, one end of the transmission shaft 2062 is interconnected with the synchronization shaft 207, and the other end of the transmission shaft 2062 is interconnected with the rotation center of the pressing arm 206, and a pressing roller 2061 is installed on the pressing arm 206, and the pressing roller 2061 vertically corresponds to the flap 205. When the lifting plate 2042 swings, the inclined rod 2071 on the synchronous shaft 207 on the lifting plate 2042 slides on the guide rail 2072. First, the inclined rod 2071 moves out of the first groove 2073, thereby driving the inclined rod 2071 to deflect as a whole. The inclined rod 2071 drives the synchronous shaft 207 to rotate, and the synchronous shaft 207 drives the transmission shaft 2062 to rotate on the mounting seat 2063. The transmission shaft 2062 drives the pressing arm 206 to deflect, and the pressing roller 2061 at the bottom of the pressing arm 206 moves downward synchronously. At this time, the pressing roller 2061 can squeeze and clamp the workpiece at the bottom, thereby fixing it. When the inclined rod 2071 moves to the second groove 2074, the inclined rod automatically resets, and the clamping position can be automatically unlocked, making the operation easier.

[0053] like Figure 5 and Figure 6 As shown, in a specific embodiment, a clamping shaft 3021 is rotatably mounted inside the positioning seat 302, and the two ends of the clamping shaft 3021 are respectively connected to the pry bar 3024 and the squeezing arm 3023. A second torsion spring 3022 is sleeved on the clamping shaft 3021, and the second torsion spring 3022 is clamped on the side wall of the positioning seat 302, and the other end is clamped on the pry bar 3024. When the protrusion 301 rotates and moves downward, the protrusion 301 as a whole is pressed downward, and the protrusion 301 can squeeze the squeezing arm 3023, and the squeezing arm 3023 rotates and twists the second torsion spring 3022, which is convenient for later resetting through the second torsion spring 3022, and after the squeezing arm 3023 rotates, the pry bar 3024 on the squeezing arm 3023 rotates, and the pry bar 3024 can push upward at this time, which is convenient for later unloading.

[0054] like Figure 3 and Figure 4As shown, further, the push block 401 is slidably arranged on the guide groove 1032 provided on the lifting platform 1031, the insertion rod 4011 is placed on the guide groove 1032, a slide plate 4012 is slidably inserted on the insertion rod 4011, the slide plate 4012 is installed at the end of the guide groove 1032, and a return spring 4013 is installed on the insertion rod 4011 located inside the guide groove 1032, one end of the return spring 4013 is clamped on the push block 401, and the other end is clamped on the slide plate 4012. During the movement of the push block 401, the return spring 4013 on the push block 401 is compressed synchronously, and the return spring 4013 is used to facilitate the subsequent return operation.

[0055] The implementation principle of the auxiliary transport device for ultra-large metal roofs in this embodiment is as follows:

[0056] First, the operator places the roof frame on the lifting plate 2042 and then starts the drive motor 2012.

[0057] The rotating disk 201 is driven by the driving motor 2012 to rotate, and the rotating disk 201 rotates counterclockwise (in Figure 5 As a reference), the position of the cam slot 202 on the turntable 201 changes synchronously, and a guide slider 2021 is meshed on the cam slot 202. At this time, the guide slider 2021, the guide rod 2022, the guide plate 2023, and the connecting rod 203 can only slide horizontally under the limit of the limit seat 2031, and the cam slot 202 can drive the guide rod 2022 and the connecting rod 203 to reciprocate horizontally. When the connecting rod 203 moves, the rocker arm 204 on the connecting rod 203 pulls the lifting plate 2042 to move, and the lifting plate 2042 rotates under the limit of the swing arm 2041, and the workpiece on the lifting plate 2042 can be tilted and lifted upward, which achieves the purpose of feeding and is simpler to operate.

[0058] When the lifting plate 2042 swings, the lifting plate 2042 slides on the limit rod 2044, and the limit slider 2047 at the bottom of the limit rod 2044 slides on the limit slide groove 2048. The limit rod 2044 mainly ensures that the lifting plate 2042 is always in a horizontal state during the swinging process to ensure that the workpiece on the lifting plate 2042 will not fall, and when the height of the lifting plate 2042 becomes higher, the lifting plate 2042 slides on the limit rod 2044, and the limit spring 2046 facilitates the subsequent resetting operation.

[0059] When the lifting plate 2042 swings, the inclined rod 2071 on the synchronous shaft 207 on the lifting plate 2042 slides on the guide rail 2072. First, the inclined rod 2071 moves out of the first groove 2073, thereby driving the inclined rod 2071 to deflect as a whole. The inclined rod 2071 drives the synchronous shaft 207 to rotate, and the synchronous shaft 207 drives the transmission shaft 2062 to rotate on the mounting seat 2063. The transmission shaft 2062 drives the pressing arm 206 to deflect, and the pressing roller 2061 at the bottom of the pressing arm 206 moves downward synchronously. At this time, the pressing roller 2061 can squeeze and clamp the workpiece at the bottom, thereby fixing it. When the inclined rod 2071 moves to the second groove 2074, the inclined rod automatically resets, and the clamping position can be automatically unlocked, making the operation easier.

[0060] When the guide slider 2021 moves to the innermost side of the cam groove 202, the guide slider 2021 will not move horizontally (at this time, the lifting plate 2042 is at the highest point), and the turntable 201 continues to rotate, and the protrusion 301 on the surface can be moved downward. The protrusion 301 is pressed downward as a whole, and the protrusion 301 can press the squeezing arm 3023. The squeezing arm 3023 rotates and twists the second torsion spring 3022. The second torsion spring 3022 is used to facilitate the later reset. After the squeezing arm 3023 rotates, The pry bar 3024 on the extrusion arm 3023 rotates, and the pry bar 3024 can be pushed upward at this time. The pry bar 3024 passes through the top groove 2054 at the bottom of the lifting plate 2042 that is already located above the pry bar 3024, driving the top flap 205 to rotate on the positioning shaft 2051, and the first torsion spring 2052 on the positioning shaft 2051 is used to facilitate later resetting. When the flap 205 rotates to a tilted state, the workpiece on the flap 205 can automatically slide onto the lifting platform 1031, thereby achieving the purpose of automatic unloading.

[0061] As the turntable 201 drives the protrusion 301 to continue to rotate, the protrusion 301 can squeeze the pressure plate 4022 of the side wall, and the pressure plate 4022 slides outward at this time. The sliding rod 4021 and the synchronous plate 402 on the pressure plate 4022 slide to the right, and the synchronous plate 402 drives the insertion rod 4011 to slide on the slide plate 4012. The insertion rod 4011 pulls the push block 401 to slide in the guide groove 1032, which can push the unloaded workpiece outward to avoid the workpieces being pushed together and affecting the subsequent unloading. During the movement of the push block 401, the reset spring 4013 on the push block 401 is synchronously compressed, and the reset operation is facilitated by the reset spring 4013 in the later stage.
