Description

Technical Field

[0001] The present invention relates to the technical field related to feeding devices, and in particular to a stable lifting structure and a feeding device for super high-rise building construction. Background Art

[0002] With the rapid growth of the social economy and the accelerated urbanization process, super high-rise buildings are proliferating like bamboo shoots after a spring. During the construction of super high-rise buildings, construction workers usually need to work at heights. When working on each floor, construction workers need to use feeding devices to transfer materials to construction workers at higher altitudes.

[0003] Nowadays, when feeding materials to heights, wire rollers and wire ropes are usually used to lift the materials. However, as the wire roller winds up the wire rope, the wire rope gradually overlaps on the wire roller. As a result, the length of the wire rope wound up gradually increases during one rotation of the wire roller, which in turn causes the speed of the material rising to gradually increase, resulting in poor stability and a safety hazard.

[0034] See also Figure 1-7 In an embodiment of the present invention, a stable lifting structure is provided, comprising a base 1, two vertical plates 2 fixedly mounted on the base 1, and a horizontal plate 3 fixed to the top ends of the two vertical plates 2, and further comprising a round roller 4, wherein the round roller 4 is movably mounted on the horizontal plate 3, the round roller 4 being connected to a translation mechanism mounted on the horizontal plate 3, the translation mechanism being connected to a power mechanism, and the power mechanism being connected to a rotation axis of the round roller 4;

[0035] A steel wire rope 5, one end of which is connected to the round roller 4, and the other end is pulled out from the round roller 4 and passed around a first guide wheel 6 rotatably mounted on the side of the transverse plate 3, and a hook 9 for lifting materials is provided at the end of the steel wire rope 5 away from the round roller 4;

[0036] a second guide wheel 16, which is in rolling engagement with the steel wire rope 5 and is connected to a transverse drive mechanism installed between the two vertical plates 2, wherein the transverse drive mechanism is used to drive the second guide wheel 16 to move along the width direction of the transverse plate 3 to change the horizontal position of the material;

[0037] A counterweight mechanism is installed on the base 1 and connected to the transverse driving mechanism.

[0038] Among them, it should be supplemented that a plurality of pulleys are installed at the bottom of the base 1, so that when in use, it is convenient for construction workers to change the working position. Of course, the pulleys are brakeable to ensure stability during the construction process.

[0039] Please refer again Figure 5 The translation mechanism includes a one-way screw 11 rotatably mounted on the transverse plate 3, a transverse rod 12 fixedly mounted on the transverse plate 3, and a translation plate 10 disposed on the one-way screw 11 and the transverse rod 12. The one-way screw 11 is threadedly connected to the translation plate 10, the transverse rod 12 is slidably connected to the translation plate 10, and the round roller 4 is rotatably mounted on the translation plate 10.

[0040] In detail, two deep holes are opened on one side of the translation plate 10 for the one-way screw rod 11 and the cross bar 12 to extend into respectively, wherein the inner wall of the deep hole into which the one-way screw rod 11 extends is provided with a thread that engages with the one-way screw rod 11.

[0041] Please refer again Figure 4 and Figure 6 The power mechanism includes a rotating shaft 7 rotatably mounted on the horizontal plate 3 and a sleeve 8 rotatably mounted on the horizontal plate 3 and connected to the rotating shaft of the round roller 4 via a second transmission belt 31. The rotating shaft 7 is connected to the one-way screw 11 via a first transmission belt 13. The sleeve 8 is slidably engaged with the rotating shaft 7 via a limiting structure. A first motor 14 is also mounted on the horizontal plate 3, and the output end of the first motor 14 is connected to the rotating shaft 7.

[0042] Furthermore, the limiting structure includes a plurality of strip-shaped protrusions 701 fixedly provided on the outer periphery of the rotating shaft 7 and a plurality of strip-shaped grooves 801 opened on the inner wall of the sleeve 8 , and the strip-shaped grooves 801 are slidably adapted to the strip-shaped protrusions 701 .

[0043] When in use, the material to be transported is lifted by the hook 9, and then the first motor 14 works to drive the rotating shaft 7 to rotate, so that the rotating shaft 7 can drive the sleeve 8 to rotate through the strip-shaped protrusion 701 and the strip-shaped groove 801, and then the sleeve 8 drives the round roller 4 to rotate through the second transmission belt 31, and the round roller 4 winds up the wire rope 5, so that the material rises.

[0044] As an example:

[0045] If the position of the round roller 4 remains unchanged when it is winding the wire rope 5, the wire rope 5 will gradually overlap on the round roller 4 as the round roller 4 rotates. Therefore, the length of the wire rope 5 wound around the round roller 4 increases with each rotation of the round roller 4, which will cause the material to rise faster and faster. Due to the large mass and inertia of the material, an excessively fast rising speed will have a great impact on the stability of the lifting.

[0046] In this application:

[0047] While the rotating shaft 7 is rotating, it will also drive the one-way screw 11 to rotate through the first transmission belt 13. Under the guidance of the cross bar 12, the translation plate 10 and the one-way screw 11 are threadedly matched, and the translation plate 10 drives the round roller 4 to move. In this way, the movement and rotation of the round roller 4 are carried out simultaneously, which can avoid the superposition phenomenon of the wire rope 5 wound on the round roller 4, thereby greatly improving the stability of material lifting.

[0048] Please refer again Figure 1 and Figure 7 The transverse driving mechanism includes a bidirectional driving assembly installed between the two vertical plates 2 and a transverse plate 17 movably arranged between the two vertical plates 2. The second guide wheel 16 is rotatably installed on one side of the transverse plate 17. The side of the transverse plate 17 facing away from the second guide wheel 16 is connected to the bidirectional driving assembly through two sets of supporting structures.

[0049] The bidirectional drive assembly includes a bidirectional screw rod 19 rotatably mounted between the two risers 2, a guide rod 20 fixedly mounted between the two risers 2, and two threaded plates 18 symmetrically arranged on the bidirectional screw rod 19. The two threaded plates 18 are threadedly connected to the bidirectional screw rod 19, and the guide rod 20 passes through the two threaded plates 18 and is slidably connected to the threaded plates 18. A second motor 15 is also mounted on the side of one of the risers 2, and the output end of the second motor 15 is connected to the bidirectional screw rod 19.

[0050] Furthermore, two through holes are provided on the side of the threaded plate 18 for the bidirectional screw rod 19 and the guide rod 20 to pass through respectively, wherein the inner wall of the through hole through which the bidirectional screw rod 19 passes is provided with a thread engaging with the bidirectional screw rod 19.

[0051] The support structure includes a first push-pull rod 21 and a second push-pull rod 22, respectively rotatably mounted on the two threaded plates 18, and a first connecting rod 23 and a second connecting rod 24, rotatably mounted on the side of the transverse plate 17 facing the threaded plate 18. The first push-pull rod 21 and the second push-pull rod 22 are hinged at their midpoints, an end of the first push-pull rod 21 away from the threaded plate 18 is connected to an end of the first connecting rod 23 away from the transverse plate 17, and an end of the second push-pull rod 22 away from the threaded plate 18 is hinged to an end of the second connecting rod 24 away from the transverse plate 17. The first connecting rod 23 and the second connecting rod 24 are connected via a sliding fit structure.

[0052] The sliding fit structure includes a through slot 26 formed on the second connecting rod 24 and a boss 25 fixed at the midpoint of the first connecting rod 23 . The boss 25 passes through the through slot 26 and is slidably connected to the second connecting rod 24 .

[0053] In actual use, since there may be obstructions of piled debris on the ground, there is a certain distance between the construction workers who are working at height and the materials being lifted, and thus it is difficult to receive the materials. At this time, the second motor 15 is started, and the second motor 15 drives the bidirectional screw rod 19 to rotate forward. Under the guidance of the guide rod 20, the two threaded plates 18 are simultaneously threadedly engaged with the bidirectional screw rod 19 and move closer to each other, and then the first push-pull rod 21 and the second push-pull rod 22 rotate, and accordingly, the first connecting rod 23 and the second connecting rod 24 rotate, and the distance between the protrusion 25 and the transverse plate 17 gradually increases, so that the transverse plate 17 drives the second guide wheel 16 to move in the direction away from the bidirectional screw rod 19, causing the wire rope 5 to bend, and the distance between the material and the vertical plate 2 gradually increases until the material is delivered to the vicinity of the construction workers at a height;

[0054] It should be noted that the first motor 14 and the second motor 15 work in conjunction, that is, after the material is lifted to a specific height, when the second motor 15 is working, the first motor 14 should drive the round roller 4 to appropriately release the wire rope 5 to keep the height of the material constant.

[0055] Please refer again Figure 1 The counterweight mechanism includes two horizontal shafts 28 fixedly mounted on the base 1 and a box 29 slidably arranged on the two horizontal shafts 28. The box 29 is used to hold the counterweight, and a vertical rod 27 is fixed to the bottom of each of the two threaded plates 18. The vertical rod 27 is connected to the box 29 through a transmission rod 30, and the two ends of the transmission rod 30 are hinged to the box 29 and the vertical rod 27 respectively.

[0056] When the material moves toward the construction workers at a higher position, the two threaded plates 18 move toward each other, and then the vertical rod 27 can push the box body 29 to slide on the two horizontal axes 28 in the direction away from the vertical plate 2 through the transmission rod 30, thereby increasing the weight of the base 1 and ensuring stability.

[0057] The present invention also proposes a feeding device for super high-rise building construction, and the feeding device for super high-rise building construction includes the stable lifting structure.

[0058] The working principle of the present invention is as follows: when in use, a counterweight is added to the box 29, the hook 9 is used to lift the material, the first motor 14 is operated, and the rotating shaft 7 is driven to rotate. Then, the rotating shaft 7 can drive the sleeve 8 to rotate through the strip-shaped protrusion 701 and the strip-shaped groove 801. Then, the sleeve 8 drives the round roller 4 to rotate through the second transmission belt 31, and the round roller 4 winds up the wire rope 5, so that the material rises;

[0059] While the rotating shaft 7 is rotating, it also drives the one-way screw 11 to rotate through the first transmission belt 13. Under the guidance of the cross bar 12, the translation plate 10 and the one-way screw 11 are threadedly engaged, and the translation plate 10 drives the round roller 4 to move. In this way, the movement and rotation of the round roller 4 are carried out simultaneously, which can avoid the overlap of the wire rope 5 wound on the round roller 4, thereby greatly improving the stability of material lifting.

[0060] In actual use, since there may be obstructions of piled debris on the ground, there is a certain distance between the construction workers who are working at height and the materials being lifted, and thus it is difficult to receive the materials. At this time, the second motor 15 is started, and the second motor 15 drives the bidirectional screw rod 19 to rotate forward. Under the guidance of the guide rod 20, the two threaded plates 18 are simultaneously threadedly engaged with the bidirectional screw rod 19 and move closer to each other, and then the first push-pull rod 21 and the second push-pull rod 22 rotate, and accordingly, the first connecting rod 23 and the second connecting rod 24 rotate, and the distance between the protrusion 25 and the transverse plate 17 gradually increases, so that the transverse plate 17 drives the second guide wheel 16 to move in the direction away from the bidirectional screw rod 19, causing the wire rope 5 to bend, and the distance between the material and the vertical plate 2 gradually increases until the material is delivered to the vicinity of the construction workers at a height;

[0061] When the material moves toward the construction workers at a higher position, the two threaded plates 18 move toward each other, and then the vertical rod 27 can push the box body 29 to slide on the two horizontal axes 28 in the direction away from the vertical plate 2 through the transmission rod 30, thereby increasing the weight of the base 1 and ensuring stability.
