Referring to Figure 1 , the high-floor unloading platform comprises a beam frame 1, a base 2 and a material conveying assembly. The base 2 is in a square plate structure, the beam frame 1 forms a square frame body for enclosing the base 2, the base 2 is fixed with the beam frame 1, the beam frame 1 has rod-shaped parts extending to the building floor and mounted on the floor concrete structure ground on opposite sides, and the base 2 has first lifting rings on opposite sides, second lifting rings are fixed outside the building concrete structure, the first lifting rings and the second lifting rings correspond to each other, a steel wire rope (not shown in the figure) is connected between the corresponding first lifting ring and the second lifting ring, and the steel wire rope and the beam frame 1 jointly support and fix the base 2, so that the base 2 plate surface is in a horizontal state. The base 2 is fixed with the enclosing plate 19 extending vertically upward on the remaining three sides except the side facing the building.

[0041] The feeding assembly is linearly moved on the base 2 towards or away from the building, and the feeding assembly is provided with a material cavity 3. The material cavity 3 is open at the top and both ends along the moving direction of the feeding assembly. When the feeding assembly is moved away from the building, the feeding assembly is accommodated on the base 2, and at this time, the building materials can be hoisted from above the feeding assembly into the material cavity 3 by a tower crane. When the feeding assembly is moved towards the building, the feeding assembly can enter the building floor, and at this time, the building materials are unloaded to improve the safety of unloading.

[0042] With reference to Figure 2 and Figure 3 Specifically, the feeding assembly comprises a base 5, a transmission seat 6, an enclosing seat 7 and a conveying belt 8. The base 5 is in the form of a square plate, and the size of the base 5 is smaller than that of the base 2. The plate surface of the base 5 is parallel to the plate surface of the base 2, and the base 5 is slid on the upper surface of the base 2 to drive the whole feeding assembly to move. The transmission seat 6 is installed on the base 5, and the enclosing seat 7 is provided with two groups and is arranged on the opposite sides of the transmission seat 6, respectively. The distribution direction of the two groups of enclosing seats 7 is perpendicular to the sliding direction of the base 5 relative to the base 2. The conveying belt 8 is located between the two groups of enclosing seats 7, and the conveying belt 8 is circularly conveyed on the transmission seat 6 along a direction perpendicular to the distribution direction of the two groups of enclosing seats 7. When the building materials enter the material cavity 3, they are placed on the conveying belt 8, and the conveying of the conveying belt 8 can drive the building materials to move out of the transmission seat 6 from the end of the transmission seat 6 close to the building, thereby assisting the unloading of the building materials.

[0043] With reference to Figure 2 Among them, the base 5 and the base 2 are provided with a driving part 4 for driving the base 5 to move. The driving part 4 comprises a first screw rod 41 and a first rotation source 42. The upper surface of the base 2 is provided with a mounting groove 20 for mounting the first screw rod 41, and the first screw rod 41 is rotationally connected in the mounting groove 20 through a bearing, and the axis direction of the first screw rod 41 is perpendicular to the distribution direction of the two groups of enclosing seats 7. The first rotation source 42 is a first rotation motor, which can be forward and reverse rotated. The first rotation motor is fixedly installed on the end of the base 2 away from the building, and the end of the first screw rod 41 away from the building extends out of the base 2 and is connected with the output end of the first rotation motor, so that the first rotation motor can drive the first screw rod 41 to rotate. The lower surface of the base 5 is integrally formed with a part extending into the mounting groove 20 and threadedly sleeved on the outer wall of the first screw rod 41. When the first screw rod 41 rotates, it drives the base 5 to move along the axis direction of the first screw rod 41, so as to drive the whole feeding assembly to displace.

[0044] With reference to Figure 3 and Figure 4The transmission seat 6 comprises a first seat body 61 and a second seat body 62 which slide relative to each other. The first seat body 61 comprises a connecting shaft 611, a first rotating sleeve 612 and a first rod 613. The connecting shaft 611 is in a cylindrical shape. The first rotating sleeve 612 is in a cylindrical shape with both ends open. The first rod 613 is in a square bar shape. The first rotating sleeve 612 has a length smaller than that of the connecting shaft 611, and the first rotating sleeve 612 is coaxially sleeved on the outer wall of the connecting shaft 611. The first rod 613 has a plurality of first connecting rings 21 fixed at one end of each first rod 613. The outer diameter of the first connecting ring 21 is consistent with the outer diameter of the first rotating sleeve 612. The first rotating sleeve 612 is provided with a first rotating groove corresponding to the first connecting ring 21 along the axis direction of the first rotating sleeve 612, so that the first connecting ring 21 is coaxially sleeved in the first rotating groove. The first rod 613 is rotatably connected to the first rotating sleeve 612 through the cooperation of the first connecting ring 21 and the corresponding first rotating groove. The distance between any two adjacent first rods 613 is consistent.

[0045] Similarly, the second seat body 62 comprises a moving shaft 621, a second rotating sleeve 622 and a second rod 623. The moving shaft 621 is in a cylindrical shape. The second rotating sleeve 622 is in a cylindrical shape with both ends open. The second rod 623 is in a square bar shape, and one end of the second rod 623 has a second connecting ring 22 with an outer diameter consistent with that of the second rotating sleeve 622. The second rotating sleeve 622 is coaxially sleeved on the outer wall of the moving shaft 621. The second rotating sleeve 622 is provided with a second rotating groove for the rotation of the second connecting ring 22. The second rod 623 is rotatably connected to the second rotating sleeve 622 along the axis direction of the second rotating sleeve 622 through the second connecting ring 22. The outer diameter of the first rotating sleeve 612 is consistent with that of the second rotating sleeve 622. The thickness of the first rod 613 is consistent with the outer diameter of the first rotating sleeve 612. The thickness of the second rod 623 is consistent with the outer diameter of the second rotating sleeve 622.

[0046] The distance between any two adjacent first rods 613 is consistent with the width of the second rod 623. The distance between any two adjacent second rods 623 is consistent with the width of the first rod 613. The first rod 613 and the second rod 623 are arranged in a spaced manner. The first rod 613 and the second rod 623 are provided with a limiting piece 13 for limiting the sliding direction of the first rod 613 and the second rod 623, so that the length direction of all the first rods 613 and the second rods 623 always remains parallel, and the upper surface and the lower surface of the first rod 613 and the second rod 623 are flush.

[0047] Referring to Figure 5The limiting piece 13 includes a limiting block 131 fixed to the first rod 613 on the side facing the second rod 623. The limiting block 131 is in the shape of a square block. A limiting slot 14 is formed in the side wall of the second rod 623 for the limiting block 131 to slide along the length direction of the second rod 623. The limiting slot 14 does not pass through the two ends of the second rod 623 away from each other, so as to guide the moving direction of the limiting block 131.

[0048] With reference to Figure 4 Each group of enclosing seats 7 includes a first enclosing plate 71 and a second enclosing plate 72. The first enclosing plate 71 and the second enclosing plate 72 are both in the shape of a square. One end of the first enclosing plate 71 is rotatably sleeved on the outer wall of one end of the first rotating sleeve 612. One end of the second enclosing plate 72 is rotatably sleeved on the outer wall of one end of the second rotating sleeve 622. The first enclosing plate 71 and the second enclosing plate 72 of the same group are located on the same side of the transmission seat 6. The end of the first enclosing plate 71 away from the first rotating sleeve 612 is provided with a sliding cavity 23 for the second enclosing plate 72 to slide away from the end of the first rotating sleeve 612. The sliding direction of the second enclosing plate 72 in the first enclosing plate 71 is parallel to the sliding direction of the first rod 613 and the second rod 623. When the first rod 613 and the second rod 623 slide relative to each other, the first enclosing plate 71 and the second enclosing plate 72 are driven to slide relative to each other.

[0049] With reference to Figure 3 And Figure 6 The upper surface of the base 5 near the building is fixed with two connecting seats 24. The upper surface of the base 5 away from the building is fixed with two extension seats 9. The distribution directions of the two connecting seats 24 and the two extension seats 9 are both perpendicular to the moving direction of the base 5. In this embodiment, the extension seat 9 extends vertically upward along the direction perpendicular to the surface of the base 5. In other embodiments, the extension seat 9 can also extend upwardly and obliquely away from the building. The two ends of the connecting shaft 611 away from each other are fixed on the two connecting seats 24 respectively. The first rotating sleeve 612 is located between the two connecting seats 24. The rotation of the first rotating sleeve 612 relative to the connecting shaft 611 makes the end of the first seat body 61 away from the second seat body 62 hinged to the base 5. The two ends of the moving shaft 621 away from each other are moved up and down on the two extension seats 9 respectively. The second rotating sleeve 622 is located between the two extension seats 9. The end of the second seat body 62 away from the first seat body 61 is connected to the extension seat 9.

[0050] With reference to Figure 3 And Figure 7The first rotating sleeve 612 is equipped with a power source 11 for driving the first rotating sleeve 612 to rotate along the axis of the connecting shaft 611. The conveyor belt 8 is simultaneously sleeved on the outer walls of both the first rotating sleeve 612 and the second rotating sleeve 622, and the conveyor belt 8 covers the outer walls of the first rod 613 and the second rod 623. There is friction between the first rotating sleeve 612 and the conveyor belt 8, and between the second rotating sleeve 622 and the conveyor belt 8, so that when the first rotating sleeve 612 rotates, it can drive the conveyor belt 8 to move, thereby driving the second rotating sleeve 622 to rotate.

[0051] The power source 11 includes a first gear 111, a second gear 112, and a power motor 113. The first gear 111 is coaxially fixedly sleeved on the outer wall of the first rotating sleeve 612 and located on the side of the first enclosure 71 away from the material cavity 3. The power motor 113 is fixedly installed on the outer wall of the connecting shaft 611 and can rotate in both directions. The second gear 112 is fixed to the output end of the power motor 113, and the first gear 111 and the second gear 112 mesh with each other, so that when the power motor 113 drives the second gear 112 to rotate, the first gear 111 rotates synchronously, so that the first rotating sleeve 612 rotates, thereby enabling the conveyor belt 8 located above the first rotating sleeve 612 and the second rotating sleeve 622 to convey from the end away from the building to the end closer to the building.

[0052] Reference Figure 3 and Figure 6 In addition, one of the extension seats 9 has a moving member 12 that drives the moving shaft 621 to move up and down. When the moving shaft 621 moves up and down relative to the extension seat 9, it drives the first rod 613 to rotate relative to the first rotating sleeve 612 and the second rod 623 to rotate relative to the second rotating sleeve 622. The first rod 613 and the second rod 623 slide relative to each other to adjust the extension length of the transmission seat 6 and the tilt angle relative to the base 5.

[0053] When the extension length of the transmission seat 6 is at its shortest, the extension directions of the first rod 613 and the second rod 623 are parallel to the surface of the base 5 plate. When the extension length of the transmission seat 6 is at its longest, the first rod 613 and the second rod 623 are inclined upward relative to the surface of the base 5 plate in the direction away from the building, thereby moving the moving shaft 621 upward during material unloading, giving the material on the conveyor belt 8 a tendency to move downward at an incline, thus assisting in material unloading. At the same time, by adjusting the extension length of the transmission seat 6, the transmission seat 6 can support building materials of different lengths. For example, when loading steel bars, the extension length of the transmission seat 6 is adjusted to its longest, so that the steel bars are placed on the conveyor belt 8 in an inclined state, and the part of the steel bars that exceeds the length of the transmission seat 6 can extend upward from the end of the second rotating sleeve 622 to the material outlet 3 without interfering with the enclosure plate 19. When loading bricks, the extension length of the transmission seat 6 is adjusted to its shortest, so that the bricks can be stacked on the conveyor belt 8 without easily tipping over.

[0054] The moving part 12 comprises a second screw rod 121 and a second rotating source 123. The two extension seats 9 are each provided with a moving groove extending through the opposite sides of the extension seat 9, the moving groove extending along the length direction of the extension seat 9 and not extending through the upper and lower ends of the extension seat 9. The second screw rod 121 is rotatably connected in the moving groove of one of the extension seats 9 in the vertical direction, and a vertically extending guide rod 25 is fixed in the moving groove of the other extension seat 9. The second rotating source 123 is a second rotating motor, which is installed on the extension seat 9 with the second screw rod 121 and can be reversely rotated. The guide rod 25 is connected with the output end of the second rotating motor, so that the second rotating motor can drive the second screw rod 121 to rotate. The two ends of the moving shaft 621 away from each other pass through the two extension seats 9 through the moving grooves, respectively, and one end of the moving shaft 621 is threadedly sleeved on the outer wall of the second screw rod 121, and the other end of the moving shaft 621 is slidably sleeved on the outer wall of the guide rod 25, so that when the second screw rod 121 rotates, the moving shaft 621 can be driven to move along the axis direction of the second screw rod 121.

[0055] With reference to Figure 6 and Figure 8 , in order to adapt the extension length of the conveying belt 8 to the extension length of the transmission seat 6, so that the conveying belt 8 remains in a taut state, the enclosing seat 7 and the conveying belt 8 have an adjusting part 10 for adjusting the length of the conveying belt 8. The adjusting part 10 comprises an adjusting shaft 101 and a third rotating source 102. The adjusting shaft 101 is fixed to the outer wall of the conveying belt 8 away from the first rotating sleeve 612 and the second rotating sleeve 622, and the extension direction of the adjusting shaft 101 is parallel to the axis direction of the first rotating sleeve 612. The third rotating source 102 is a third motor connected to one end of the adjusting shaft 101, and the third motor can drive the adjusting shaft 101 to rotate in opposite directions. When the conveying belt 8 is conveying, the adjusting shaft 101 and the third motor move together with the conveying belt 8.

[0056] With reference to Figure 4 , in the two groups of enclosing seats 7, the first sliding groove 15 is formed on the first enclosing plate 71 of one of the enclosing seats 7 and faces the material cavity 3. The first sliding groove 15 extends through the sliding cavity 23 of the first enclosing plate 71 and through the side of the first enclosing plate 71 facing the second enclosing plate 72. The second sliding groove 16 is formed on the second enclosing plate 72 and faces the material cavity 3. The second sliding groove 16 extends through the side of the second enclosing plate 72 facing the first enclosing plate 71. The first sliding groove 15 and the second sliding groove 16 are connected and continuous, and are both formed along the conveying direction of the adjusting shaft 101.

[0057] With reference to Figure 3, another group of first enclosure base 2 71 on the opening of the third chute 26 toward the material cavity 3, the third chute 26 through to the first sliding plate 71 23 in the cavity and through the first sliding plate 71 toward the second sliding plate 72 side, the second sliding plate 72 on the opening of the fourth chute 27 toward the material cavity 3, the fourth chute 27 through the second sliding plate 72 toward the first sliding plate 71 side, the third chute 26 and the fourth chute 27 are connected and connected in succession, the third chute 26 and the fourth chute 27 are opened along the conveying direction of the adjusting shaft 101.

[0058] Referring to Figure 3 and Figure 8 , the adjusting shaft 101 away from the third motor end into the first chute 15 and the second chute 16, the adjusting shaft 101 through the first chute 15 and the second chute 16 slip on the enclosure seat 7. The third motor into the third chute 26 and the fourth chute 27, the third motor through the third chute 26 and the fourth chute 27 slip on the enclosure seat 7. The third motor appears square, so that the third motor in the third chute 26 and the fourth chute 27 is not easy to rotate when rotating.

[0059] The first chute 15 and the third chute 26 have the same extension direction, the second chute 16 and the fourth chute 27 have the same extension direction, the first chute 15, the second chute 16, the third chute 26 and the fourth chute 27 are used for moving the adjusting shaft 101 and the third motor from the bottom of the second rotating sleeve 622 to the top of the second rotating sleeve 622, and then moving to the top of the first rotating sleeve 612 close to the building.

[0060] When the second rotating source 123 drives the second screw 121 to rotate, the moving shaft 621 moves up or down, the third rotating motor drives the adjusting shaft 101 to rotate, so as to wind or unwind the conveyor belt 8, thereby adjusting the length of the conveyor belt 8.

[0061] Referring to Figure 2 and Figure 7 , further, the base 5 close to the building side through the pin shaft hinged with the baffle 17, the baffle 17 upper surface is inclined surface, and the base 5 and the baffle 17 have a displacement source 18 for driving the baffle 17 to rotate. The displacement source 18 is an electric push rod, the base end of the electric push rod is hinged to the connecting seat 24 of the base 5, and the telescopic end of the electric push rod is hinged to the baffle 17. When the telescopic end of the electric push rod retracts, the baffle 17 is driven to rotate to the baffle 17 plate surface perpendicular to the base 5 plate surface, at this time, the baffle 17 can block the material in the material cavity 3 from moving out of the material cavity 3, improving the stability of the material in the material cavity 3 when the base 5 moves. When the telescopic end of the electric push rod extends, the baffle 17 is driven to rotate to the baffle 17 plate surface together with the base 5 plate surface, which guides the movement of the material. At this time, the inclined surface of the baffle 17 inclines downward away from the hinge point of the baffle 17.

[0062] The implementation principle of the high-level unloading platform according to an embodiment of the present application is as follows: before placing the building materials, the adjusting shaft 101 is rotated to below the second rotating sleeve 622. Before placing the building materials, the materials are first moved to the material cavity 3 by the tower crane and placed on the conveying belt 8, and the moving shaft 621 is moved according to the length and size of the materials, so that the first rod 613 and the second rod 623 and the first surrounding plate 71 and the second surrounding plate 72 are relatively shifted, to adjust the extension length of the transmission seat 6 for supporting the materials and the size of the material cavity 3, and meanwhile the third motor drives the adjusting shaft 101 to rotate to adjust the length of the conveying belt 8. After the materials are placed in the material cavity 3, the first screw rod 41 is rotated to drive the base 5 to move into the building floor, then the baffle 17 is rotated to extend with the base 5 by the electric push rod, and then the power motor 113 is started to rotate forward to drive the conveying belt 8 to convey, until the adjusting shaft 101 moves to above the first rotating sleeve 612, so that the materials on the conveying belt 8 are unloaded. After the materials are unloaded, the power motor 113 is reversely rotated to drive the adjusting shaft 101 to move below the second rotating sleeve 622 again, and the base 5 is moved back to the base 2.

[0063] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
