Description

Technical Field

[0001] This utility model relates to the field of truss beam technology, and in particular to a large-tonnage truss beam anti-shaking and stabilizing device for horizontal rotation and vertical hoisting. Background Technology

[0002] In the field of large-scale building steel structure hoisting, the traditional horizontal-to-vertical hoisting operation of large-tonnage truss beams faces the following technical challenges:

[0003] Insufficient stability: During the process of changing the truss beam from flat to vertical, it is prone to violent shaking due to the change in the center of gravity. Traditional hoisting methods rely on a single hoisting point or flexible ropes for fixation, which is difficult to suppress multi-directional shaking and poses a risk of structural instability.

[0004] Low positioning accuracy: During the hoisting process, manual assistance is required to adjust the posture of the truss beam, which is complicated and difficult to control the rotation angle precisely, resulting in a decrease in installation efficiency.

[0005] To address the aforementioned issues, this invention proposes an anti-shake stabilization device that integrates multi-directional clamping, dynamic support, and angle control functions. Through mechanical-servo synergy, it achieves stable control throughout the entire process of truss beam hoisting. Utility Model Content

[0006] The purpose of this invention is to address the instability issues in existing technologies: during the process of truss beams being moved from a horizontal position to an vertical position, severe swaying is easily generated due to the change in the center of gravity. Traditional hoisting methods rely solely on a single hoisting point or flexible ropes for fixation, which is insufficient to suppress multi-directional shaking, posing a risk of structural instability and resulting in low positioning accuracy. Furthermore, manual assistance is required to adjust the posture of the truss beams during hoisting, which is complex and makes it difficult to precisely control the rotation angle, leading to a decrease in installation efficiency. Therefore, this invention proposes a large-tonnage truss beam horizontal-to-vertical hoisting anti-shaking stabilization device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A large-tonnage truss beam anti-shaking stabilization device for horizontal-to-vertical hoisting includes a truss beam body. Both sides of the truss beam body have integrally formed side protrusions. Multiple strip-shaped grooves are formed at the top and bottom of the truss beam body. The bottom surface of the grooves on the side protrusions is horizontally higher than the inner wall of the bottom of the strip-shaped grooves. Multiple arc-shaped steel components are welded to one side of the truss beam body. These arc-shaped steel components are used to support the truss beam body when it is rotated. The device also includes:

[0009] A crossbar, one end of which is fixedly connected to a connecting hanging plate, and one side of the connecting hanging plate is rotatably connected to a rotating hanging plate via a connecting assembly. One side of the rotating hanging plate is provided with a clamping assembly for clamping a side protrusion plate.

[0010] The outer wall of the crossbar is slidably fitted with a support assembly, which is located on the other side of the clamping assembly. The support assembly is used to support the other side of the truss beam body.

[0011] In one possible design, the connecting assembly includes a rectangular seat fixedly connected to one side of the rotating hanging plate. The top of the rectangular seat on the side away from the rotating hanging plate has a rectangular groove. The inner walls of the two sides of the rectangular groove are rotatably connected to the same rotating shaft. The outer wall of the rotating shaft is fixedly connected to the connecting hanging plate.

[0012] In one possible design, the clamping assembly includes a rectangular groove formed on one side of the rotating hanging plate, with the same first clamping plate slidably connected between the inner walls of the two sides of the rectangular groove, and a second clamping plate fixedly connected to the bottom of one side of the rotating hanging plate. Both the second clamping plate and the first clamping plate are used in conjunction with a side protrusion plate to clamp the side protrusion plate from both the top and bottom directions.

[0013] In one possible design, an adjusting screw is rotatably connected to the top inner wall of the rectangular groove. The adjusting screw is threaded through the first clamping plate and is used to drive the first clamping plate to move up and down. The bottom of the adjusting screw rotatably passes through the rotating hanging plate, and a nut is fixedly sleeved on the outer wall of the adjusting screw.

[0014] In one possible design, the support assembly includes a side plate with two symmetrically arranged strip holes inside. The crossbar has a rectangular hole inside, and the strip holes slide through the crossbar. The side plate is located inside the rectangular hole. A support plate is fixedly connected to one bottom side of the side plate, and the top of the support plate has multiple serrated grooves to increase friction.

[0015] In one possible design, the side plate has a threaded hole inside, a servo motor is fixedly connected to one side of the crossbar, the output shaft of the servo motor rotates through the crossbar and is fixedly connected to a lead screw, one end of the lead screw extends into the interior of the rectangular hole and rotates to connect with the inner wall of one side of the rectangular hole, and the lead screw thread passes through the threaded hole to drive the side plate to move laterally.

[0016] In one possible design, both the first clamping plate and the second clamping plate have slots on their sides that are close to each other, and the inner wall of one side of each slot has an arc-shaped groove.

[0017] In one possible design, hooks are fixedly connected to both sides of the top of the crossbar for connecting to a suspension rope.

[0018] In this application, during use, the rotating hanging plate is adjusted to a vertical state, and the rotating hanging plate is engaged with the upper and lower sides of the side protrusion from one side, so that the second clamping plate is located below the side protrusion and the first clamping plate is located above the side protrusion. The servo motor is started, and the output shaft of the servo motor drives the lead screw to rotate. The lead screw drives one end of the side plate to move laterally, and the side plate drives the support plate to move laterally. At this time, the side plate approaches the truss beam body from the other side, thereby pressing the other side of the truss beam body against it. The support plate is located below the truss beam body.

[0019] Hang the corresponding ropes on the hooks. At this time, the horizontal bar can be moved upward using a crane or gantry. The support plate supports the bottom of the truss beam body. The second clamping plate clamps the bottom of the side convex plate and makes the bottom of the side convex plate enter the corresponding slot, ensuring the stability of the side convex plate connection. The arc groove setting can help the side convex plate to be clamped into the slot.

[0020] At this point, the nut can be turned, which drives the adjusting screw to rotate. The adjusting screw drives the first clamping plate to move down, and the first clamping plate abuts against the side convex plate. At this time, the first clamping plate and the second clamping plate clamp the side convex plate from the top and bottom sides. Together with the support plate on the other side, the clamping process is completed. After clamping, the main body of the truss beam can be hoisted from the transport vehicle to the placement location.

[0021] At this point, the main body of the truss beam is placed horizontally on the ground. After contact with the ground, the servo motor can be started. The servo motor drives the lead screw to rotate in the opposite direction, moving the side plate away from the main body of the truss beam. After the support plate is separated from the bottom of the main body of the truss beam, the main body of the truss beam is only clamped by the first and second clamping plates on one side. At this time, the entire device is moved upward again by a crane or gantry crane. Since one side of the main body of the truss beam is in contact with the device, the main body of the truss beam begins to rotate. At the same time, the arc surface of the circular steel component contacts the ground, which helps the main body of the truss beam to rotate. The rotating hanging plate begins to drive the rectangular seat to rotate. Since the inner wall of the rectangular groove is equipped with rubber pads, the resistance between the rectangular groove and the connecting hanging plate is large, increasing the friction. Until the main body of the truss beam is adjusted from the horizontal state to the vertical state, one side of the inner wall of the rectangular groove abuts against one side of the connecting hanging plate, and the main body of the truss beam can no longer rotate. At this time, several circular steel components are cut off to control the rotation angle. After the adjustment is completed, the nut is turned to separate the rotating hanging plate from the main body of the truss beam, completing the hoisting process.

[0022] When a large component is being hoisted by a single crane and is about to transition to a three-dimensional position, a sudden lateral force may appear due to the change in stress conditions. This lateral force has a significant impact on the overall stability of the crane and poses a major safety hazard. At the same time, the stress points of the component are prone to deformation during the "horizontal to vertical" process. After multiple discussions and studies, it was found that if the rotating area is designed with an arc-shaped component, the entire hoisting process can be smoothly transitioned. Ultimately, we installed an arc-shaped steel component on the rotating facade of the component.

[0023] Beneficial effects:

[0024] The first clamping plate and the second clamping plate are clamped in opposite directions by adjusting the screw. With the help of the arc-shaped groove guide design, the side convex plate is accurately engaged in the slot to form a rigid constraint.

[0025] A servo motor drives a lead screw to move the support plate laterally. The serrated groove increases the friction coefficient, enabling stepless support adjustment on the other side of the truss beam and avoiding deformation due to unilateral stress.

[0026] Rotational damping control: The frictional contact between the rubber pad on the inner wall of the rectangular groove and the connecting hanging plate provides controllable rotational resistance during the horizontal-to-vertical process, reducing the rotational angular velocity by more than 60% and effectively suppressing inertial vibration.

[0027] By controlling the automatic clutch engagement and disengagement of the support plate through the forward and reverse rotation of the servo motor, and in conjunction with the rotational positioning function of the rotating hanging plate, millimeter-level precision control of attitude conversion from 0° to 90° is achieved, eliminating errors caused by human intervention.

[0028] During the release phase, the clamping force is quickly released using the nuts, and the mechanical limiting of the rectangular seat and the connecting hanging plate ensures that the truss beam is untied before it is completely vertical, thus avoiding sudden collapse.

[0029] The arc-shaped groove design of the slot is compatible with side convex plates of different thicknesses, and the adjusting screw provides a clamping stroke of 50-500mm. A single device can meet the hoisting needs of truss beams ranging from 3 to 15 tons. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] Example 1

[0039] In the field of large-scale building steel structure hoisting, traditional large-tonnage truss beam horizontal-to-vertical hoisting operations present the following technical challenges: Insufficient stability: During the process of converting the truss beam from horizontal to vertical, the change in the center of gravity easily causes violent swaying. Traditional hoisting methods rely solely on a single lifting point or flexible ropes for fixation, which is insufficient to suppress multi-directional shaking, posing a risk of structural instability. Low positioning accuracy: During hoisting, manual assistance is required to adjust the truss beam's posture, which is complex and makes it difficult to precisely control the rotation angle, resulting in reduced installation efficiency.

[0040] Regarding the above issues:

[0041] Reference Figure 1-6 This utility model proposes a hoisting device, including: a truss beam body 1, with side protrusions 3 integrally formed on both sides of the truss beam body 1; multiple strip-shaped grooves 2 are formed on the top and bottom of the truss beam body 1; the bottom surface of the grooves of the side protrusions 3 is horizontally higher than the bottom inner wall of the strip-shaped grooves 2; multiple arc-shaped steel components 26 are welded to one side of the truss beam body 1, and the arc-shaped steel components 26 are used to support the truss beam body 1 when it is flipped; and it also includes:

[0042] A crossbar 6 has a connecting plate 9 fixedly connected to one end. A rotating plate 4 is rotatably connected to one side of the connecting plate 9 via a connecting assembly. The connecting assembly includes a rectangular seat 8 fixedly connected to one side of the rotating plate 4. A rectangular groove 11 is provided on the top of the side of the rectangular seat 8 away from the rotating plate 4. The same rotating shaft 10 is rotatably connected between the inner walls of the two sides of the rectangular groove 11. The outer wall of the rotating shaft 10 is fixedly connected to the connecting plate 9. The corresponding lifting rope is hung on the hook 7. At this time, the crossbar 6 can be moved upward using a crane or gantry crane. At this time, the support plate 18 supports the bottom of the truss beam body 1. The second clamping plate 22 clamps the bottom of the side protrusion 3 and makes the bottom of the side protrusion 3 enter the corresponding slot 20, ensuring the stability of the side protrusion 3 connection. The arc groove 21 helps the side protrusion 3 to be clamped into the slot 20. A clamping assembly for clamping the side protrusion 3 is provided on one side of the rotating plate 4. The clamping assembly includes a rectangular groove 21 provided on one side of the rotating plate 4. 4. A first clamping plate 19 is slidably connected between the inner walls of both sides of the rectangular groove 24. A second clamping plate 22 is fixedly connected to the bottom of one side of the rotating hanging plate 4. Both the second clamping plate 22 and the first clamping plate 19 are used to cooperate with the side protrusion 3 to clamp the side protrusion 3 from both the top and bottom. An adjusting screw 25 is rotatably connected to the inner wall of the top of the rectangular groove 24. The adjusting screw 25 is threaded through the first clamping plate 19 and is used to drive the first clamping plate 19 to move up and down. The bottom of the adjusting screw 25 rotates... The rotating plate 4 is driven through the adjustment screw 25. The outer wall of the adjustment screw 25 is fixedly fitted with a nut 23. At this time, the nut 23 can be rotated, and the nut 23 drives the adjustment screw 25 to rotate. The adjustment screw 25 drives the first clamping plate 19 to move down. The first clamping plate 19 abuts against the side protrusion 3. At this time, the first clamping plate 19 and the second clamping plate 22 clamp the side protrusion 3 from the top and bottom sides. With the cooperation of the support plate 18 on the other side, the clamping process is completed. After clamping, the truss beam body 1 can be lifted from the transport vehicle to the placement location.

[0043] A support assembly is slidably fitted onto the outer wall of the crossbar 6. The support assembly is located on the other side of the clamping assembly and is used to support the other side of the truss beam body 1. The support assembly includes a side plate 5, with two symmetrically arranged strip holes 16 inside the side plate 5. A rectangular hole 12 is opened inside the crossbar 6. The strip holes 16 slide through the crossbar 6, and the side plate 5 is located inside the rectangular hole 12. A support plate 18 is fixedly connected to the bottom of one side of the side plate 5. Multiple serrated grooves 17 are opened on the top of the support plate 18 to increase friction. A threaded hole 15 is opened inside the side plate 5. A servo motor 14 is fixedly connected to one side of the crossbar 6. The output shaft of the servo motor 14 rotates. A through-bar 6 is fixedly connected to a lead screw 13. One end of the lead screw 13 extends into the interior of a rectangular hole 12 and is rotatably connected to the inner wall of one side of the rectangular hole 12. The lead screw 13 is threaded through a threaded hole 15 and is used to drive the side plate 5 to move laterally, adjusting the rotating hanging plate 4 to a vertical position, and causing the rotating hanging plate 4 to engage with the upper and lower sides of the side protrusion 3 from one side, so that the second clamping plate 22 is located below the side protrusion 3 and the first clamping plate 19 is located above the side protrusion 3. The servo motor 14 is started, and the output shaft of the servo motor 14 drives the lead screw 13 to rotate. The lead screw 13 drives the side plate 5 to move laterally at one end, and the side plate 5 drives the support plate 18 to move laterally. At this time, the side plate 5 moves laterally from the other side. The side plate 18 is positioned below the truss beam body 1, allowing it to be placed horizontally on the ground. Once in contact with the ground, the servo motor 14 is activated, causing the lead screw 13 to rotate in the opposite direction, moving the side plate 5 away from the truss beam body 1. After the support plate 18 disengages from the bottom of the truss beam body 1, the truss beam body 1 is now held only by the first clamping plate 19 and the second clamping plate 22 on one side. The entire device is then moved upwards again using a crane or gantry crane. As one side of the truss beam body 1 contacts the device, the truss beam body 1 begins to rotate, and simultaneously... The curved surface of the arc steel component 26 contacts the ground, which helps the truss beam body 1 to rotate. The rotating hanging plate 4 starts to drive the rectangular seat 8 to rotate. Since the inner wall of the rectangular groove 11 is equipped with a rubber pad, the resistance between the rectangular groove 11 and the connecting hanging plate 9 is large, which slows down the rotation speed of the truss beam body 1. Until the truss beam body 1 is adjusted from a horizontal state to a vertical state, one side of the inner wall of the rectangular groove 11 abuts against one side of the connecting hanging plate 9, and the truss beam body 1 can no longer rotate. At this time, multiple arc steel components 26 are cut off to control the rotation angle. After the adjustment is completed, the nut 23 is turned to separate the rotating hanging plate 4 from the truss beam body 1, completing the hoisting process.

[0044] This application can be used in the field of truss beams, or in other fields applicable to this application.

The inner wall of one side of the slots 20 is provided with arc-shaped grooves 21. The top two sides of the crossbar 6 are fixedly connected with hooks 7, which are used to connect with the lifting rope.
