[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0038] Embodiment 1, as Figures 1 to 10 As shown, an automatic handling robot for a smart construction site includes a support unit 100, a material receiving and locking unit 200 and a lifting unit 300. The support unit 100 includes a transverse plate 103. Control boxes 101 are installed on both side walls of the transverse plate 103. A driving wheel 102 is installed at the bottom of the control box 101. A pair of guide plates 1013 are installed on the transverse plate 103 on the same side of the control box 101. The driving wheel 102 can be controlled to rotate by the electronic components inside the control box 101 (and the electronic components controlling the rotation of the driving wheel is a prior art, so the working principle will not be repeated here), thereby achieving the purpose of transportation.

[0039] The material receiving and locking unit 200 includes a driving motor 201, which is mounted at the bottom of the horizontal plate 103. A screw shaft 2012 is mounted at the output end of the driving motor 201. A screw sleeve 202 is meshed with the screw shaft 2012. A guide sleeve 203 is mounted on the outer wall of the screw sleeve 202. The diameter of the guide sleeve 203 is smaller than the diameter of the screw sleeve 202. A slope 2031 is arranged at the connection between the guide sleeve 203 and the screw sleeve 202. The guide sleeve 203, the slope 2031 and the side wall of the screw sleeve 202 are provided with a plurality of guide sleeves 2031, 2031 and 202. A bending slide 2032 is provided with a synchronous rod 2041 which is slidably arranged on the bending slide 2032, and push rods 204 are installed on both sides of the synchronous rod 2041, the push rods 204 movably penetrate the horizontal plate 103, a receiving plate 205 is installed on the top of the push rod 204, a plurality of pairs of partitions 2052 are installed on the receiving plate 205, a folding frame 206 is rotatably installed on the receiving plate 205, a pressure roller 2061 is installed on the folding frame 206, a pressure arm 2062 is installed at the rotation center of the folding frame 206, and the pressure arm 2062 is in an inclined state. When the supported pipe fittings need to be transported, the operator starts the driving motor, and the driving motor drives the screw shaft to rotate, and the screw sleeve on the screw shaft slides synchronously. At this time, the screw sleeve can drive the guide sleeve to move, and the position of the bending slide groove on the guide sleeve changes, and then the synchronous rod and the push rod at the bottom move downward, and the push rod can move the receiving plate with the pipe fittings downward, so that the two ends of the pipe fittings are respectively located on both sides of the guide plate, ensuring that the pipe fittings will not slip off the robot, and the overall center of gravity of the equipment is lowered, which can make the robot more stable. When the receiving plate moves to the lowest point, the pressure arm and the bottom are squeezed, and then the pressure arm rotates, and the pressure arm drives the folding frame to rotate and flip inward. At this time, the pressure roller can squeeze the pipe fittings and fix the pipe fittings, making the pipe fittings more stable during transportation. The lifting and locking of the present invention are both realized by mechanical structure, so the reliability is stronger, and the manufacturing cost and later maintenance cost are lower.

[0040] The lifting unit 300 includes a lifting plate 301, which is movably plugged into the inner side of the control box 101. The lifting plate 301 is equipped with an insertion rod 302, and a connecting rod 3022 is installed on the insertion rod 302. A swing arm 3031 is rotatably installed on the side wall of the connecting rod 3022. A push rod 303 is rotatably installed at the end of the swing arm 3031. The push rod 303 movably penetrates the side wall of the control box 101, and the end of the push rod 303 is connected to the guide sleeve 203. In the process of the guide sleeve sliding and driving the receiving plate to move downward, the push rod moves to both sides at this time, and the swing arm angle at the end of the push rod changes. The swing arm pushes the entire connecting rod to move upward, and the connecting rod drives the insertion rod and the lifting plate to move upward. At this time, the lifting plate shrinks upward to ensure that the driving wheel can contact the ground again at this time. In the initial stage, the lifting plate lifts the entire device to ensure that the device can always remain stable when loading pipe fittings.

[0041] like Figures 1 to 10 As shown, in a specific embodiment, a fence 1012 is installed on one of the control boxes 101, and the height of the fence 1012 is not higher than the height of the guide plate 1013. Other materials that need to be transported can be placed in the inner cavity of the fence 1012. A reinforcing rib 1011 is installed on the other control box 101, and the reinforcing rib 1011 is in an inclined state. The end of the reinforcing rib 1011 is interconnected with the side wall of the guide plate 1013, and the guide plate 1013 is L-shaped. The reinforcing rib 1011 ensures the stability of the connection of the control box 101.

[0042] like Figures 1 to 10 As shown, further, a side panel 1031 is installed on the side wall of the horizontal panel 103, a base 1033 is installed on the bottom of the side panel 1031, and an inspection door 1032 is installed on the side wall of the side panel 1031. The inspection door 1032 is interconnected with the cavity surrounded by the bottom of the horizontal panel 103 and the top of the base 1033. The height of the side panel 1031 is higher than the height of the guide plate 1013, and the inspection door 1032 is convenient for later maintenance and repair.

[0043] Embodiment 2, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figures 1 to 10 As shown, the housing of the driving motor 201 is welded with a mounting seat 2011, which is welded and arranged at the bottom of the horizontal plate 103. The mounting seat 2011 is in the shape of a boss. The driving motor 201 is a dual-axis motor. The end of the screw sleeve 202 is clamped with a bearing, and the outer wall of the bearing is clamped with a bearing seat 2013, which is welded to the bottom of the horizontal plate 103. The driving motor 201 drives the screw shaft 2012 connected to the output shaft to rotate, and at this time, the screw shaft 2012 rotates inside the bearing seat 2013, which serves the purpose of limiting.

[0044] like Figures 1 to 10 As shown, in a specific embodiment, a pair of slide plates 2021 are symmetrically installed on the side wall of the screw sleeve 202, and a slide bar 2022 is movably installed on the slide plate 2021. A limit seat 2024 is installed at both ends of the slide bar 2022. The limit seat 2024 is welded and set at the bottom of the horizontal plate 103. A limit spring 2023 is sleeved on the slide bar 2022, one end of the limit spring 2023 is clamped on the limit seat 2024, and the other end of the limit spring 2023 is clamped on the side wall of the slide plate 2021. After the screw shaft 2012 rotates, the screw sleeve 202 limited on the screw shaft 2012 begins to slide, and the slide plate 2021 on the screw sleeve 202 slides on the slide bar 2022 at this time, and the limit spring 2023 on the slide plate 2021 is compressed synchronously, and the limit spring 2023 is convenient for the later reset operation.

[0045] like Figures 1 to 10As shown, further, the guide sleeve 203 is movably sleeved on the outer side of the screw shaft 2012, and a slide seat 2042 is slidably provided on the side wall of the bending slide groove 2032, and a guide wheel 2043 is rotatably installed on the slide seat 2042, and the outer wall of the guide wheel 2043 is rollingly connected with the inner wall of the bending slide groove 2032, and the slide seat 2042 is welded and arranged at the center of the synchronization rod 2041. When the screw sleeve 202 slides, the screw sleeve 202 can drive the guide sleeve 203 to move, and the positions of the guide sleeve 203, the ramp 2031 and the screw sleeve 202 change synchronously, at this time, the bending slide groove 2032 located inside the guide sleeve 203, the ramp 2031 and the screw sleeve 202 slide synchronously horizontally, and the slide seat 2042 and the guide wheel 2043 slidably connected inside the bending slide groove 2032 slide downward along the ramp 2031 at this time, and then the synchronization rod 2041 at the bottom moves downward synchronously.

[0046] Embodiment 3, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figures 1 to 10 As shown, the receiving plate 205 is placed in a chamber between a pair of guide plates 1013, and an anti-slip groove is provided on the surface of the receiving plate 205. A return spring 2051 is sleeved on the side wall of the push rod 204, one end of the return spring 2051 is installed at the bottom of the receiving plate 205, and the other end of the return spring 2051 is clamped on the cross plate 103. A notch 2053 is provided on the receiving plate 205, and the pressure arm 2062 movably passes through the notch 2053. A lifting block 2063 is installed at the bottom of the cross plate, and the lifting block 2063 corresponds to the receiving plate 205. In the process of the synchronization rod 2041 driving the push rod 204 to move downward, the push rod 204 can drive the receiving plate 205 equipped with the pipe fittings to move downward, and finally the two ends of the pipe fittings can be respectively located on both sides of the guide plate 1013, ensuring that the pipe fittings will not slip off the robot in the process of following the movement of the robot, and because the pipe fittings move downward as a whole, the center of gravity of the entire robot is lowered, which can make the robot more stable and ensure the stability during transportation, and when the receiving plate 205 moves downward, the receiving plate 205 and the cross plate 103 are close to each other, and the reset spring 2051 between the two is compressed, and the reset spring 2051 is used to facilitate later reset.

[0047] like Figures 1 to 10As shown, in a specific embodiment, a rotating shaft 2071 is welded at the connection between the pressure arm 2062 and the folding frame 206, a positioning seat 207 is rotatably installed on the end of the rotating shaft 2071, and the positioning seat 207 is welded to the vertical rod of the receiving plate 205, an arch bracket 2072 is installed on the positioning seat 207, and the arch bracket 2072 and the rotating shaft 2071 are rotatably connected, a torsion spring 2073 is sleeved on the rotating shaft 2071, one end of the torsion spring 2073 is clamped on the arch bracket 2072, and the other end of the torsion spring 2073 is clamped on the rotating shaft 2071. When the receiving plate 205 moves to the lowest point, the pressure arm 2062 and the lifting block 2063 at the bottom are squeezed, and then the pressure arm 2062 rotates, and the pressure arm 2062 drives the folding frame 206 to rotate and flip inward. At this time, the pressure roller 2061 rotates and squeezes toward the position of the receiving plate 205, and then the pipe fittings can be squeezed to fix the pipe fittings, making the pipe fittings more stable during transportation. In the process of rotation of the folding frame 206, the rotating shaft 2071 on the folding frame 206 rotates on the positioning seat 207 and the arch bracket 2072. At this time, the clamped torsion spring 2073 is twisted synchronously, and the torsion spring 2073 is used to facilitate the subsequent resetting operation.

[0048] like Figures 1 to 10 As shown, further, an anti-skid pad 3011 is installed at the bottom of the lifting plate 301, and a baffle 3012 is installed at the top of the lifting plate 301. The baffle 3012 is slidably set in the sliding cavity 3013 opened inside the control box 101. An extrusion spring 3021 is sleeved on the plug rod 302 located inside the sliding cavity 3013. One end of the extrusion spring 3021 is mutually engaged with the inner wall of the sliding cavity 3013, and the other end of the extrusion spring 3021 is mutually connected with the baffle 3012. The swing arm 3031 is in an inclined state, the push rod 303 is in a horizontal state, and a synchronous plate 3032 is installed at the end of the push rod 303. The synchronous plate 3032 and the guide sleeve 203 are mutually connected. A travel switch 3023 is installed in the inner cavity of the control box 101, and the travel switch 3023 corresponds vertically to the connecting rod 3022. When the lifting plate 301 is slidably supported, the lifting plate 3012 is automatically lifted and the lifting plate 3013 is automatically lifted.

[0049] The implementation principle of an automatic transport robot for a smart construction site in this embodiment is as follows:

[0050] When the pipe fittings need to be transported, the operator first needs to move the pipe fittings as a whole onto the receiving plate 205. Figure 2 As shown, the robot is in loading mode at this time, and the lifting plate 301 is in contact with the ground, lifting the entire device to ensure the stability of the robot.

[0051] When loading, the operator needs to stack the transversely arranged pipes into the receiving plate 205 , and the pipes are separated by the partitions 2052 at this time, and the length of the pipes is smaller than the gap between the guide plates 1013 .

[0052] After loading is completed, the operator needs to start the drive motor 201, and the drive motor 201 drives the screw shaft 2012 connected to the output shaft to rotate. At this time, the screw shaft 2012 rotates inside the bearing seat 2013, which serves the purpose of limiting. After the screw shaft 2012 rotates, the screw sleeve 202 on the screw shaft 2012 that is limited starts to slide, and the slide plate 2021 on the screw sleeve 202 slides on the slide bar 2022 at this time, and the limit spring 2023 on the slide plate 2021 is compressed synchronously, and the limit spring 2023 facilitates the reset operation later.

[0053] When the screw sleeve 202 slides, the screw sleeve 202 can drive the guide sleeve 203 to move, and the positions of the guide sleeve 203, the ramp 2031 and the screw sleeve 202 change synchronously. At this time, the bending slot 2032 located inside the guide sleeve 203, the ramp 2031 and the screw sleeve 202 slide synchronously horizontally, and the sliding seat 2042 and the guide wheel 2043 slidingly connected inside the bending slot 2032 slide downward along the ramp 2031 at this time, and then the synchronization rod 2041 at the bottom moves downward synchronously, and the synchronization rod 2041 drives the top rod 204 to move downward, and the top rod 204 can drive the receiving plate 205 equipped with the pipe fitting to move downward, and finally, the two ends of the pipe fitting can be respectively located on both sides of the guide plate 1013, ensuring that the pipe fitting will not slip off the robot during the movement of the robot following the robot, and because the pipe fitting moves downward as a whole, the center of gravity of the entire robot is lowered, which can make the robot more stable and ensure stability during transportation.

[0054] When the receiving plate 205 moves downward, the receiving plate 205 and the cross plate 103 are close to each other, and the return spring 2051 therebetween is compressed, and the return spring 2051 is used to facilitate the later return. When the receiving plate 205 moves to the lowest point, the pressure arm 2062 and the lifting block 2063 at the bottom are squeezed, and then the pressure arm 2062 rotates, and the pressure arm 2062 drives the folding frame 206 to rotate and flip inward. At this time, the pressure roller 2061 rotates and squeezes toward the position of the receiving plate 205, and then the pipe fittings can be squeezed to fix the pipe fittings, making the pipe fittings more stable during transportation. In the process of rotation of the folding frame 206, the rotating shaft 2071 on the folding frame 206 rotates on the positioning seat 207 and the arch bracket 2072. At this time, the clamped torsion spring 2073 is synchronously twisted, and the torsion spring 2073 is used to facilitate the later return operation.

[0055] During the sliding of the guide sleeve 203, the guide sleeve 203 drives the synchronous plate 3032 to slide to both sides. At this time, the synchronous plate 3032 can drive the push rod 303 to move to both sides. The angle of the swing arm 3031 at the end of the push rod 303 changes. The swing arm 3031 pushes the entire connecting rod 3022 to move upward. When the connecting rod 3022 moves to the specified position, the travel switch 3023 is triggered, and the driving wheel 102 can be unlocked (the travel switch 3023 unlocks the driving wheel 102 as a prior art, so the working principle No further details will be given here), and when the connecting rod 3022 moves, the connecting rod 3022 can drive the insertion rod 302 and the lifting plate 301 to move upward. When the lifting plate 301 slides upward, the baffle 3012 on the lifting plate 301 slides inside the sliding cavity 3013, and the extrusion spring 3021 is squeezed synchronously. The extrusion spring 3021 is used to facilitate the subsequent resetting operation. The purpose of the lifting plate 301 contracting upward is to ensure that the driving wheel 102 can contact the ground again at this time, so as to facilitate the subsequent robot to transport the pipe.
