Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a dismantling device and a dismantling method. Background Technology

[0002] Lifting refers to the process of moving equipment to a desired location using a lifting mechanism, and it is an indispensable task in fields such as construction. To complete lifting operations, lifting tools are typically used, such as hooks, lifting rings, lifting suction cups, clamps, and forks. In current technology, winches or high-powered lifting machinery are commonly used to lift the lifting tools to meet the weight requirements of ultra-large components.

[0003] However, despite the advanced capabilities of high-powered hoisting machinery, it still cannot fully meet hoisting requirements. Specifically, due to the large mass of ultra-large components, their acceleration during startup or shutdown is also significant, resulting in a substantial impulse. This impulse may exceed the maximum load-bearing capacity of the hoisting machinery, acting horizontally to cause tilting and deformation of the support columns, leading to the safety hazard of the component falling. In construction work, a falling component can cause serious safety accidents. Summary of the Invention

The balancer is connected to one end of the third cable, and the other end of the third cable is connected to a second cable. The third cable is configured to be slidably connected to each of the pulleys so that the balancer can move along the vertical direction to provide a balancing force.

[0010] In some embodiments, the second hydraulic crawler includes a first component and a second component, the second component being configured to define an inner cavity, the second steel cable passing through the first component and the second component, the first component being configured to move in the inner cavity along the vertical direction, the second component including an upper end and a lower end along the vertical direction, the second hydraulic crawler including a first operating state and a second operating state, in the first operating state the first component abuts against the lower end, and in the second operating state the first component abuts against the upper end.

[0011] In some embodiments, the first component includes a first clamping member configured to secure the second steel cable when transitioning from the second operating state to the first operating state, and the second component includes a second clamping member configured to secure the second steel cable when transitioning from the first operating state to the second operating state.

[0012] In some embodiments, from the first working state to the second working state, the displacement distance of the first component is L, which satisfies: 270mm≤L≤330mm.

[0013] In some embodiments, the truss structure includes a through hole and a connecting portion, the lifting assembly is configured to be connected to the connecting portion, the through hole is located above the connecting portion along the vertical direction, and the second steel cable passes through the through hole.

[0015] In some embodiments, the balancing assembly includes a reaction member disposed at one end of the support column opposite to the lifting assembly along the vertical direction, and the first steel cable is connected to the reaction member.

[0016] A second aspect of this embodiment also provides a disassembly method, the disassembly method using any of the disassembly devices described in the above embodiments, the disassembly method comprising:

[0017] S1: Install the disassembly device on the truss structure and the support column;

[0025] Compared with the prior art, the beneficial effects of this application are:

[0026] In the technical solution of this application, one end of a lifting device assembly is connected to a support column, and the other end is connected to a truss structure. The lifting device assembly is configured to lower the truss structure after its dismantling is completed. In operation, the lifting device assembly is subjected to the gravity of the truss structure. Therefore, the lifting device assembly provides tension to the support column along the direction from the first hydraulic crawler to the lifting device assembly, causing the support column to deform and eventually collapse. The first hydraulic crawler is located at the horizontal end of the support column opposite to the lifting device assembly. One end of a first steel cable is connected to the first hydraulic crawler, and the other end of the first steel cable is connected to the vertical end of the support column opposite to the lifting device assembly. The first hydraulic crawler stretches the first steel cable, and since the other end of the first steel cable is connected to the vertical end of the support column opposite to the lifting device assembly, the first steel cable provides tension to the first hydraulic crawler. When the lifting device assembly provides tension to the support column, the first hydraulic crawler provides tension in the horizontal direction. The dismantling device disclosed in this application can provide a pulling force along the direction from the lifting assembly to the first hydraulic crawler through a balancing component, so as to balance the lateral pulling force generated by the truss structure descent, thereby ensuring the stability of the support column when the truss structure is descending, increasing the support column's ability to resist bending moment, ensuring that the support column does not deform, and improving the stability of the dismantling device.

[0068] Although high-powered hoisting machinery is very advanced, it still cannot fully meet hoisting requirements. Specifically, due to the large mass of the components themselves, the acceleration during startup or shutdown is also significant, resulting in a large impulse. This impulse may exceed the maximum load-bearing capacity of the hoisting machinery, acting horizontally and causing the support columns to tilt and deform, leading to the safety hazard of the component falling. In construction work, if a component falls, it can lead to a serious safety accident.

[0069] To solve the above problems, see [link to relevant documentation]. Figures 1 to 11 This application discloses a dismantling device 10, which is connected to a support column 20 for dismantling a truss structure 30. It should be noted that the dismantling device can be used to dismantle various types of truss structures 30; see [link to relevant documentation]. Figure 1 This includes a heavy-duty truss structure 30. The mass of the heavy-duty truss structure 30 is greater than or equal to 2t, specifically, the mass of the heavy-duty truss structure 30 can be 2t, 3t, 4t, 5t, etc. The support column 20 can be configured in various shapes. In some embodiments, the support column 20 can be cuboid. In other embodiments, the support column 20 can also be cylindrical. In other embodiments, the support column 20 can also be polygonal, etc. The dismantling device includes a lifting assembly 100 and a balancing assembly 200. In some embodiments, the dismantling device includes multiple lifting assemblies 100, each lifting assembly 100 connected to the same support column 20, so that the dismantling device is suitable for large truss structures 30, requiring multiple lifting assemblies 100 to keep the truss structure 30 stable, so that the truss structure 30 is not prone to overturning. The specific number of lifting assemblies 100 can be determined according to the actual situation. For example, the lifting assemblies 100 can be two, three, four, etc. It should be noted that the lifting assemblies 100 can be arranged at uniform intervals or non-uniform intervals. In some embodiments, the dismantling device includes multiple balancing components 200, each lifting component 100 being connected to the same support column 20, so that the dismantling device is suitable for situations where it is necessary to ensure that the support column 20 is subjected to horizontal force in multiple directions without deformation. The specific number of balancing components 200 can be determined according to the actual situation; for example, the balancing components 200 can be two, three, four, etc. It should be noted that the balancing components 200 can be arranged at uniform intervals or non-uniform intervals.

[0070] See Figures 2 to 4One end of the lifting assembly 100 is connected to the support column 20, and the other end is connected to the truss structure 30. The lifting assembly 100 is configured to lower the truss structure 30 after dismantling. In operation, the lifting assembly 100 is subjected to the gravity of the truss structure 30. Therefore, the lifting assembly 100 provides a tensile force to the support column 20 along the direction from the first hydraulic crawler 210 to the lifting assembly 100, causing the support column 20 to deform. When the deformation of the support column 20 exceeds its deformation limit, the tensile force provided by the lifting assembly 100 is too large, causing the support column 20 to collapse. In some embodiments, to prevent the truss structure 30 from descending too quickly, the lifting assembly 100 further provides a tensile force to ensure that the truss structure 30 descends at a uniform speed, preventing damage to the truss structure 30. This also increases the tensile force provided by the lifting assembly 100 to the support column 20, further causing the support column 20 to deform. Furthermore, to prevent the truss structure 30 from descending too quickly, the lifting device assembly 100 provides additional tension to allow the truss structure 30 to descend in steps at certain intervals, thus preventing damage to the truss structure 30. During this stepping motion, the truss structure 30 undergoes multiple start-stop movements, generating multiple impacts on the support column 20. Due to these impacts, the tension provided by the lifting device assembly 100 to the support column 20 increases, further causing deformation of the support column 20.

[0071] The balancing assembly 200 includes a first hydraulic crawler 210 and a first steel cable 220. The first hydraulic crawler 210 is located at one end of the support column 20 in the horizontal direction away from the lifting assembly 100. One end of the first steel cable 220 is connected to the first hydraulic crawler 210, and the other end of the first steel cable 220 is connected to one end of the support column 20 in the vertical direction away from the lifting assembly 100. The specific number of first steel cables 220 can be determined according to the actual situation. For example, the first steel cables 220 can be set to two, three, four, etc. The first hydraulic crawler 210 stretches the first steel cable 220. Since the other end of the first steel cable 220 is connected to the one end of the support column 20 in the vertical direction away from the lifting assembly 100, the first steel cable 220 provides tension to the first hydraulic crawler 210. When the lifting assembly 100 provides tension to the support column 20, the first hydraulic crawler 210 provides tension in the horizontal direction. The dismantling device 10 disclosed in this application can provide tension along the direction from the lifting assembly 100 to the first hydraulic crawler 210 through the balancing component 200, so as to balance the lateral tension generated by the descent of the truss structure 30, increase the ability of the support column 20 to resist bending moment, so as to ensure the stability of the support column 20 when the truss structure 30 is descended, ensure that the support column 20 does not deform, and improve the stability of the dismantling device 10. In some embodiments, the balancing component 200 includes a balancing pulley 140, and a first steel cable 220 passes through the balancing pulley 140 to ensure that the tension of the first steel cable 220 is fully applied to the first hydraulic crawler 210, so as to balance the lateral tension generated by the descent of the truss structure 30 and ensure that the support column 20 does not deform.

[0072] It should be noted that the other end of the first steel cable 220 is connected to the end of the support column 20 that is vertically opposite to the lifting device assembly 100, wherein the end of the support column 20 that is vertically opposite to the lifting device assembly 100 can be close to the ground. Due to the tension generated by the lifting device assembly 100, the support column 20 deforms as a whole. To improve the stability of the dismantling device 10, it is necessary to reduce the degree of deformation of the support column 20. The balancing component 200 acts on the support column 20 from the end connected to the first hydraulic crawler 210 to the other end connected to the first steel cable 220. Therefore, by allowing the end of the support column 20 that is vertically opposite to the lifting device assembly 100 to be close to the ground, the balancing component 200 expands its range of action on the support column 20, ensuring that the support column 20 does not deform and improving the stability of the dismantling device 10. Furthermore, the other end of the first steel cable 220 is fixed to the ground, so that the balancing component 200 can further expand the range of action on the support column 20, further ensure that the support column 20 does not deform, and further improve the stability of the disassembly device 10.

[0073] See Figure 2 as well as Figure 6The lifting device assembly 100 includes a second hydraulic crawler 110 and a second steel cable 120. The second hydraulic crawler 110 is disposed at one end of the support column 20. The specific number of second steel cables 120 can be determined according to the actual situation. For example, the second steel cables 120 can be set to two, three, four, etc. In some embodiments, the support column 20 includes an unremoved structure extending in the horizontal direction. In the vertical direction, the second hydraulic crawler 110 is disposed on the unremoved structure to ensure that the second steel cable 120 is configured to connect the second hydraulic crawler 110 and the truss structure 30 in the vertical direction, ensuring that the tension of the truss structure 30 from the second steel cable 120 is in the vertical direction, so that the truss structure 30 is stable during descent, thereby improving the stability of the dismantling device 10. One end of the second steel cable 120 is connected to the second hydraulic crawler 110, and the other end of the second steel cable 120 is connected to the truss structure 30. The second hydraulic crawler 110 is disposed at the end of the second steel cable 120 near the support column 20. The second hydraulic crawler 110 stretches the second steel cable 120. Since the other end of the second steel cable 120 is connected to the truss structure 30, the second hydraulic crawler 110 provides tension to the second steel cable 120, and the second steel cable 120 provides tension to the truss structure 30 to ensure the truss structure 30 descends stably and to prevent damage to the truss structure 30.

[0074] See Figure 5The lifting assembly 100 includes a balancing member 130, multiple pulleys 140, and a third steel cable 160. The specific number of pulleys 140 can be determined according to actual conditions; for example, two, three, four, etc., pulleys 140 can be provided. The specific number of third steel cables 150 can also be determined according to actual conditions; for example, two, three, four, etc., third steel cables 150 can be provided. It should be noted that the third steel cable 150 corresponds one-to-one with the second steel cable 120. The balancing member 130 is connected to one end of the third steel cable 150, and the other end of the third steel cable 150 is connected to the second steel cable 120. The third steel cable 150 is configured to slide on each pulley 140 to allow the balancing member 130 to move vertically and provide balancing force. When the tension of the second hydraulic crawler 110 is too small, the balancing member 130 provides tension to each pulley 140 to ensure the stable descent of the truss structure 30. Since the truss structure 30 is obtained through disassembly, its structure is relatively complex, and the material density is difficult to determine. Therefore, the center of gravity of the truss structure 30 is difficult to determine. In some embodiments, when lowering the truss structure 30, it is connected to multiple disassembly devices 10. Each disassembly device 10 is connected to an end of the truss structure 30, and each disassembly device 10 includes a balancer 130, multiple pulleys 140, and a third steel cable 160. Before the truss structure 30 is lowered, the mass of each balancer 130 is adjusted to balance the uneven force on each disassembly device 10 caused by the uncertain center of gravity. This ensures that the tension provided by each disassembly device 10 is the same or has a small difference when the truss structure 30 is lowered, ensuring the stability of the truss structure 30 during descent and preventing damage to the truss structure 30.

[0075] See Figures 6 to 9The second hydraulic crawler 110 includes a first component 111 and a second component 112. A truss structure 30 is disposed below the second component 112 in the vertical direction. The second component 112 is configured to define an inner cavity 113. The first component 111 can be configured in various shapes. In some embodiments, the first component 111 can be a cuboid. In other embodiments, the first component 111 can also be a cylinder. In other embodiments, the first component 111 can also be a polygon, etc. It is understood that the second component 112 can also be configured in various shapes including the inner cavity 113. In some embodiments, the second component 112 can be a cuboid. In other embodiments, the second component 112 can also be a cylinder. In other embodiments, the second component 112 can also be a polygon, etc. A second steel cable 120 passes through the first component 111 and the second component 112. The second steel cable 120 is configured to switch between being slidably connected to the first component 111 and being fixedly connected to the first component 111, and the second steel cable 120 is also configured to switch between being slidably connected to the second component 112 and being fixedly connected to the second component 112. The first component 111 is configured to move vertically within the inner cavity 113. The second component 112 includes an upper end portion 1121 and a lower end portion 1122 along the vertical direction. The second hydraulic crawler 110 includes a first operating state and a second operating state. In the first operating state, the first component 111 abuts against the lower end portion 1122; in the second operating state, the first component 111 abuts against the upper end portion 1121. In some embodiments, adjustment between the first and second operating states is achieved by filling or draining oil into the inner cavity 113.

[0076] Further, see Figures 6 to 9The first component 111 includes a first clamping member 1111, configured to fix the second steel cable 120 when transitioning from the second working state to the first working state. The second component 112 includes a second clamping member 1123, configured to fix the second steel cable 120 when transitioning from the first working state to the second working state. It should be noted that in some embodiments, when the second hydraulic crawler 110 transitions from the first working state to the second working state, the second clamping member 1123 clamps to fix the second component 112 and the second steel cable 120, and the first clamping member 1111 releases to allow a sliding connection between the first component 111 and the second steel cable 120. Oil is then injected into the inner cavity 113, causing the first component 111 to move upwards in the vertical direction, while the second component 112 and the second steel cable 120 remain fixed. When the first component 111 abuts against the upper end 1121, oil filling into the inner cavity 113 stops, and the second hydraulic crawler 110 is in the second working state. When the second hydraulic crawler 110 transitions from the second working state to the first working state, the first clamping member 1111 clamps to fix the first component 111 and the second steel cable 120, and the second clamping member 1123 releases to allow the second component 112 and the second steel cable 120 to slide together. Oil is then drained from the inner cavity 113, causing the first component 111 and the second steel cable 120 to move downwards in the vertical direction, while the second component 112 remains stationary, and the truss structure 30 moves downwards with the second steel cable 120. When the first component 111 abuts against the lower end 1122, oil draining from the inner cavity 113 stops, and the second hydraulic crawler 110 is in the first working state. By switching between the first and second working states, the truss structure 30 descends in steps, ensuring stable descent. Furthermore, when the second hydraulic crawler 110 transitions from the first working state to the second working state, when the distance between the first component 111 and the upper end 1121 is M, the first clamping member 1111 clamps the second steel cable 120, and the first component 111 continues to move upward in the vertical direction to stretch the second steel cable 120 located between the first clamping member 1111 and the second clamping member 1123. This ensures that the second steel cable 120 between the first clamping member 1111 and the second clamping member 1123 is kept taut, preventing the second hydraulic crawler 110 from transitioning from the second working state to the first working state. This prevents the second steel cable 120 from becoming slack and failing to provide tension to the truss structure 30, causing the truss structure 30 to fall rapidly and generate a large impact force. Furthermore, the distance M satisfies: 20mm ≤ L ≤ 30mm, to ensure a significant stretching effect on the second steel cable 120 without damaging it. For example, the distance M can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm or 30mm.

[0077] In some embodiments, from the first working state to the second working state, the displacement distance of the first component 111 is L, that is, when the truss structure 30 descends in steps, the descent distance of the truss structure 30 each time is L, where L satisfies: 270mm≤L≤330mm, to ensure that the descent rate of the truss structure 30 is relatively fast and that the second steel cable 120 is not damaged. Exemplarily, the distance M can be 270mm, 280mm, 290mm, 300mm, 310mm, 320mm, or 320mm.

[0078] In some embodiments, see Figure 10 In the vertical direction, the connecting part 40 is located below the center of gravity of the truss structure 30 to ensure that the tension of the truss structure 30 under the second steel cable 120 is located below, making it less susceptible to horizontal forces and preventing the truss structure 30 from overturning. Furthermore, in the vertical direction, the through hole 50 is located above the center of gravity of the truss structure 30 to ensure that the balancing force of the second steel cable 120 is evenly distributed across the truss structure 30, thus stabilizing the truss structure 30 when it overturns.

[0079] The balancing assembly 200 includes a reaction member 230, which is disposed at one end of the support column 20 in the vertical direction opposite to the lifting device assembly 100. The reaction member 230 extends horizontally out of the lifting device assembly 100. A first steel cable 220 is connected to the reaction member 230, such that the first steel cable 220 is vertically connected to both the reaction member 230 and the first hydraulic crawler 210, ensuring that the tension on the reaction member 230 is vertical and that the balancing assembly 200 is stable under force. In some embodiments, the reaction member 230 includes a reaction plate extending horizontally and a support plate supporting the reaction plate.

[0080] The truss structure 30 includes a through hole 50 and a connecting portion 40. A lifting assembly 100 is configured to connect to the connecting portion 40. Vertically, the through hole 50 is located above the connecting portion 40. A first steel cable 220 passes through the through hole 50 to ensure that the first steel cable 220 passes through the truss structure 30, preventing the truss structure 30 from being subjected to horizontal forces that could cause it to overturn. When the truss structure 30 overturns, the first steel cable 220 acts through the connecting portion 40 and the through hole 50, generating a force in the opposite direction to stabilize the truss structure 30.

[0081] See Figure 11The dismantling device 10 includes a tensioning assembly disposed horizontally opposite to the reaction member 230 to balance the tension generated by the balancing assembly 200. The tensioning assembly includes a fourth steel cable. One end of the fourth steel cable is connected to the truss structure 30, and the other end is connected to the support column 20. A third hydraulic crawler is provided at the end of the fourth steel cable connected to the truss structure 30. The tensioning assembly is configured such that when the truss structure 30 descends, the third hydraulic crawler tightens the fourth steel cable, causing the tensioning assembly to generate a downward vertical tension on the truss structure 30, thereby reducing the horizontal sway of the truss structure 30 and stabilizing it. In some embodiments, the dismantling device 10 includes multiple tensioning assemblies to accommodate the action of multiple reaction members 230. Exemplarily, the tensioning assemblies may be two, three, four, etc.

[0082] A second aspect of this application also provides a disassembly method, see [link to disassembly method]. Figure 12 The disassembly method uses any one of the disassembly devices 10 described in the above embodiments. The disassembly method includes S1: installing the disassembly device 10 on the truss structure 30 and the support column 20. S2: using a first hydraulic crawler 210 to stretch the first steel cable 220 and using a second hydraulic crawler 110 to stretch the second steel cable 120, so as to ensure that the first steel cable 220 and the second steel cable 120 are taut, so that the truss structure 30 is stable during the cutting process. S3: cutting the truss structure 30 and the support column 20. S4: using the second hydraulic crawler 110 to lift the truss structure 30. In step S4, the second hydraulic crawler 110 lifts the truss structure 30, providing a stable upward pulling force to ensure that the truss structure 30 and the support column 20 are completely disconnected, so as to prevent incomplete disconnection between the truss structure 30 and the support column 20, which would cause the support column 20 to exert an impact force on the truss structure 30 when the second hydraulic crawler 110 lowers the truss structure 30, resulting in poor stability of the truss structure 30. S5: Lower the truss structure 30 using the second hydraulic crawler 110, and the balancing assembly 200 resists the bending moment on the support column 20. S6: Place the truss structure 30 on the ground to ensure its complete stability. S7: Use the first hydraulic crawler 210 to loosen the first steel cable 220, and use the second hydraulic crawler 110 to loosen the second steel cable 120, ensuring that the first and second steel cables 220 are loosened, thus stabilizing the dismantling device 10 during dismantling. S8: Dismantle the dismantling device 10.
