[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Example 1:

[0031] like Figures 1-8 As shown, the unmanned intelligent tower crane device based on BIM and RFID technology in this embodiment of the invention includes a base 1, two clamping plates 2 disposed at the bottom of the base 1, a bottom groove 4 opened on the bottom surface of the base 1, a first threaded rod 5 rotatably connected to the inner cavity of the bottom groove 4, a first threaded sleeve 7 threadedly connected to both sides of the outer peripheral surface of the first threaded rod 5, and an anti-slip mechanism for improving the stability of clamping materials. The bottom of the first threaded sleeve 7 is fixed to the top surface of the adjacent clamping plate 2.

[0032] By controlling the tower crane to move the device to the top position of the material to be grabbed, the two clamping plates 2 are positioned on both sides of the material, and the inner surface of the clamping plates 2 is made to fit against the top surface of the material. Then, the motor 6 is started to rotate the first threaded rod 5. Since the inner cavity of the bottom groove 4 can act as a stop and limit for the first threaded sleeve 7, and the external thread structures on both sides of the outer circumference of the first threaded rod 5 are set in opposite directions, the gap between the two clamping plates 2 is reduced under the cooperation of the threaded connection between the first threaded sleeve 7 and the first threaded rod 5, thereby clamping the material. When the material is lifted, the anti-slip mechanism can improve the stability of the material clamping and prevent it from slipping.

[0033] like Figures 1-8 As shown, the anti-slip mechanism includes an extension assembly and a support assembly;

[0034] The extension assembly comprises a second threaded rod 8 rotatably connected to the inner surface of the clamping plate 2, a second threaded sleeve 9 threadedly connected to the outer surface of the second threaded rod 8, a sliding plate 3 fixed to the side surfaces of the two second threaded sleeves 9 away from each other, a second threaded sleeve 9 fixed to the side surface of one of the first threaded sleeves 7, a rotating shaft 11 penetratingly rotatably connected to the middle position of the first threaded sleeve 7, a first bevel gear 10 fixedly sleeved on the second threaded rod 8 extending into the inner cavity of the adjacent first threaded sleeve 7, a second bevel gear 12 fixedly sleeved on the rotating shaft 11 located in the inner cavity of the adjacent first threaded sleeve 7, and a first abutting component for connecting the two rotating shafts 11, wherein the first bevel gear 10 and the adjacent second bevel gear 12 are in meshing connection, and one side of one of the rotating shafts 11 is fixed to the output end of the second threaded sleeve 9.

[0035] By starting the second threaded sleeve 9 to rotate one of the rotating shafts 11, the two rotating shafts 11 can be synchronously rotated under the action of the first abutting effect, and the two second threaded rods 8 can be synchronously rotated in the same direction under the meshing action between the second bevel gear 12 and the adjacent first bevel gear 10, and the second threaded sleeve 9 can be abutted and limited by the inner surface of the second threaded rod 8, so that the two sliding plates 3 can be synchronously moved in the vertical direction under the meshing action between the second threaded sleeve 9 and the adjacent second threaded rod 8, and the extension height of the sliding plate 3 in the vertical direction can be adjusted according to the different height dimensions of the materials.

[0036] As shown in Figures 1-8 , the first abutting component comprises a first insertion column 14 fixed to the side of the rotating shaft 11 close to the second threaded sleeve 9 and a first rectangular slot 13 penetratingly formed in the middle position of the other rotating shaft 11, and the first rectangular slot 13 and the first insertion column 14 are in penetrating insertion connection.

[0037] When the second threaded sleeve 9 is started to rotate one of the rotating shafts 11, the first insertion column 14 can be rotated to synchronously rotate the other rotating shaft 11 in the same direction under the abutting action between the first insertion column 14 and the first rectangular slot 13.

[0038] As shown in Figures 1-8 , the support assembly comprises two sliding rods 16 slidingly inserted into the bottom surface of the sliding plate 3, a support seat 15 fixed to the side surfaces of the two sliding rods 16 away from each other, a connecting plate 18 fixed to the side surfaces of the two sliding rods 16 away from each other, an abutting seat 41 fixed to the bottom surface of the clamping plate 2, and a rebound positioning component acting on the connecting plate 18.

[0039] The support base 15 is positioned by the rebound positioning component when moving to the bottom of the material clamped by the clamping plate 2, and the support base 15 can adhere to the surface of the bottom of the material under the action of the extension assembly, so that the bottom of the material is no longer in a suspended state, thereby avoiding the situation that the material slips due to excessive weight or too smooth sides, and the support base 15 does not move horizontally when supporting under the limiting action of the rebound positioning assembly, thereby improving the stability of the supported material, and the support base 15 moves vertically upward under the action of the extension assembly when unloading, so that the support base 15 is separated from the bottom of the material under the abutting action of the abutting seat 41 and the action of the rebound positioning component, and the material can be unloaded.

[0040] As shown in Figures 1-8 , the rebound positioning component includes a first spring 17 sleeved on the outer surface of the sliding rod 16 and an electromagnetic column 19 fixed to the surface of the link plate 18 and the sliding plate 3 located at the middle position of the two sliding rods 16, one side of the first spring 17 is fixed to the surface of the adjacent position of the sliding plate 3, and the other side of the first spring 17 is fixed to the surface of the adjacent position of the link plate 18.

[0041] When the sliding plate 3 does not move vertically downward, the support base 15 adheres to the surface of one side of the clamping plate 2, and at this time the first spring 17 is in a compressed state, and when the sliding plate 3 moves vertically downward to drive the support base 15 to move vertically downward, the support base 15 adheres to the surface of the material clamped by the clamping plate 2, and at this time the first spring 17 is still in a compressed state, until the sliding plate 3 drives the support base 15 to move to the bottom of the material, the support base 15 moves to the surface of the bottom of the material under the action of the rebound force of the first spring 17 and the two adjacent electromagnetic columns 19 adhere to each other, and the electromagnetic columns 19 are opened, so that the two adjacent electromagnetic columns 19 can position the support base 15 under the magnetic attraction therebetween, and when the extension assembly drives the support base 15 to move vertically upward during unloading, the two electromagnetic columns 19 are closed, so that the two support bases 15 can expand the distance therebetween under the abutting action of the abutting seats 41 located at adjacent positions, so that the support base 15 is separated from the bottom of the clamped material, thereby enabling the material to be unloaded when the distance between the clamping plates 2 is expanded.

[0046] And in this process, the scanning range of the center plate 21 is improved through the action of the translation assembly, so as to avoid the situation that the center plate 21 fails to scan the RFID chip due to a certain error in the installation of the RFID chip, and the protection assembly can guide the movement track of the center plate 21 when the sliding plate 3 moves vertically and avoid the collision between the connecting seat 20 and the RFID reader 22 when the two clamping plates 2 move towards each other.

[0047] Referring to Figure 1 Figure 8 ​, it is worth mentioning that the translation component includes a rotating rod 27 rotatably connected to the middle of the surface of one end of the center plate 21, a rotating disc 23 fixed to the surface of one end of the rotating rod 27, a sleeve 24 arranged on the surface of the rotating disc 23, a contact rod 25 inserted into the inner cavity of the sleeve 24, a connecting plate 26 fixed to the upper and lower ends of the rotating disc 23, a tooth seat 28 fixed to the surface of one end of one of the clamping plates 2, an activity rod 29 rotatably connected to the surface of one of the connecting seats 20, a circular gear 30 fixedly sleeved on one end of the outer circumferential surface of the activity rod 29, two activity shafts 32 rotatably connected to the position of one side of one of the connecting seats 20 and the surface of the center plate 21 close to the rotating rod 27, a third bevel gear 31 fixedly sleeved on the other end surface of the activity rod 29 and the third bevel gear 31 on the outer circumferential surface of the rotating rod 27, a fourth bevel gear 33 fixedly sleeved on the outer circumferential surface of the activity shaft 32, an opening 42 through the center plate 21 at the position of one side of the circular gear 30 and a second contact component for connecting the two activity shafts 32, the circular gear 30 and the tooth seat 28 are in meshing connection, the third bevel gear 31 and the activity shaft 32 in the adjacent position are in meshing connection, the activity rod 29 and the opening 42 are in through insertion connection, one end of the contact rod 25 is fixed to the surface of the rotating disc 23, and one end of the connecting plate 26 is fixed to the surface of the RFID reader 22;

[0048] When the sliding plate 3 moves in the vertical direction, the meshing action between the circular gear 30 and the tooth seat 28 is caused, so that the activity rod 29 rotates, so that one of the activity shafts 32 rotates under the meshing action between the two third bevel gears 31 and the fourth bevel gears 33, so that the other activity shaft 32 can rotate under the action of the second contact component, so that the rotating rod 27 rotates under the meshing action between the other two third bevel gears 31 and the fourth bevel gears 33, so that the rotating disc 23 drives the contact rod 25 to make circular motion, so that the sleeve 24 can move back and forth in the horizontal direction under the contact of the contact rod 25, so that the RFID reader 22 can move back and forth in the horizontal direction, so that the scanning range of the RFID reader 22 can be expanded, and when the two clamping plates 2 move towards each other, the activity rod 29 can slide in the inner cavity of the opening 42 to support the activity rod 29.

[0049] Referring to Figure 1 - Figure 8 , it is worth mentioning that the second contact component includes a second rectangular slot 34 through the middle position of the activity shaft 32 and a second insertion column 35 through the middle position of the two second rectangular slots 34;

[0050] When one of the movable shafts 32 rotates, the other movable shaft 32 can be rotated under the resistance of the second insertion column 35 and the two second rectangular grooves 34.

[0052] When the center plate 21 moves along the vertical direction with the sliding plate 3, the limiting seat 38 slides along the outer surface of the embedded shaft 37 in the inner cavity of the storage groove 36, so as to support and limit the movement track of the center plate 21, and make the movement track more stable.

[0053] With reference to Figure 1 - Figure 8 Figure 1 Figure 8 It is worth mentioning that the protection assembly further comprises two positioning seats 39 arranged outside the middle position of the first threaded rod 5 and a second spring 40 fixed to the sides of the two positioning seats 39 away from each other, the positioning seats 39 being fixed to the inner cavity of the bottom groove 4.
