Abstract
Description
Technical Field
[0001] This invention relates to the field of prefabricated building construction technology, and more specifically, to a prefabricated building module hoisting equipment. Background Technology
[0002] In the construction industry, hoisting equipment is widely used to improve construction efficiency and shorten the construction cycle. With the development of technology and social needs, prefabricated buildings are becoming increasingly popular. Prefabricated building modules are transported to designated locations by hoisting equipment for rapid assembly and construction, which can greatly reduce on-site construction time.
[0003] Luffing jib tower cranes, commonly used in prefabricated building construction, offer advantages such as high lifting capacity, flexible operation, and wide coverage. However, during hoisting, the horizontal rotation of building modules generates horizontal forces on the crane, potentially causing vertical deflection and deformation, affecting its lifespan and posing safety hazards. Furthermore, as the boom length increases, the lifting weight decreases, limiting the weight and range of building modules that can be lifted. This necessitates dividing the crane into more modules during prefabrication, increasing on-site splicing points and significantly reducing the efficiency of prefabricated building construction. Summary of the Invention
[0004] This invention provides a prefabricated building module hoisting equipment to solve the problems of deflection and deformation, shortened service life, and construction safety hazards caused by building modules in existing hoisting equipment.
[0005] This invention provides a prefabricated building module hoisting device, including a horizontally arranged crossbeam tie rod assembly. Both ends of the crossbeam tie rod assembly are connected to a vertical support assembly via a first connecting part and a second connecting part, respectively. The bottom of the vertical support assembly is provided with a movable pulley system. The bottom of the crossbeam tie rod assembly is provided with a lifting assembly that can move horizontally along the crossbeam tie rod assembly, and the lifting assembly is used to lift building modules. When subjected to load, the crossbeam tie rod assembly can convert the horizontal force into its own tension or compression force through internal mechanical balance, thereby eliminating the horizontal force.
[0006] Furthermore, the crossbeam tie rod assembly includes a horizontally arranged main beam, with end crossbeams vertically arranged at both ends of the main beam in the horizontal direction. The ends of the two end crossbeams on the same side are connected by arc-shaped arch ribs, forming two arch ribs on both sides of the end crossbeams. Vertically parallel hangers are arranged between the arch ribs and the main beam at intervals. Tie rods parallel to the main beam are arranged between the two end crossbeams, and the tie rods are connected to the end crossbeams.
[0007] Furthermore, the crossbeam tie rod assembly also includes a tie beam, and the position where the hanger rod and the main beam are joined forms a first connection point, with the tie beam connecting two oppositely arranged first connection points.
[0008] Furthermore, the crossbeam tie rod assembly also includes a cross brace, and the position where the hanger and the arch rib meet forms a second connection point, with the cross brace connecting two oppositely arranged second connection points.
[0009] Furthermore, the first connecting part includes, from top to bottom, a top plate, a first central shaft, a bottom plate, and an anti-falling rod; the top surface of the top plate is fixedly connected to the bottom surface of the end crossbeam; the bottom surface of the top plate is fixedly connected to the top surface of the first central shaft; the bottom of the first central shaft is cylindrical, and the bottom plate is provided with a through circular hole, through which the first central shaft passes and is fixed at the bottom of the bottom plate by the anti-falling rod; the circular hole restricts the displacement of the first central shaft in the horizontal direction.
[0010] Furthermore, the second connecting part includes, from top to bottom, a top plate, a second central shaft, a bottom plate, and an anti-falling rod; the top surface of the top plate is fixedly connected to the bottom surface of the end crossbeam; the bottom surface of the top plate is fixedly connected to the top surface of the second central shaft; the bottom of the second central shaft is cylindrical, and the bottom plate is provided with a through circular hole, through which the second central shaft passes and is fixed at the bottom of the bottom plate by the anti-falling rod; the circular hole and the second central shaft are clearance-fitted in the horizontal direction.
[0011] Furthermore, the lifting assembly includes an electric hoist that can move on the main beam, the electric hoist being connected to and providing traction to the sling, the end of the sling being provided with a hook.
[0012] Furthermore, the electric hoists are a set, and each hook is equipped with a balance hoisting assembly consisting of a hoisting rope and a balance beam.
[0013] Furthermore, the vertical support assembly consists of a vertical trunk, a horizontal bar, and diagonal bars.
[0014] Furthermore, it also includes a lateral support portion, which extends obliquely upward from both ends of the pulley assembly and converges to the vertical support assembly, forming a triangular structure with the pulley assembly and the vertical support assembly.
[0015] The prefabricated building module hoisting equipment of the present invention has vertical support components connected to both ends of the horizontal tie rod assembly via a first connecting part and a second connecting part, respectively. The bottom of the vertical support assembly is equipped with a movable pulley system. The bottom of the horizontal tie rod assembly is equipped with a lifting group that can move horizontally along the horizontal tie rod assembly, and the lifting group is used to lift the building module. The movement of the building module is achieved by the pulley system driving the hoisting equipment and the horizontal movement of the lifting group along the horizontal tie rod assembly, reducing the horizontal force on the hoisting equipment during movement. Simultaneously, when the horizontal tie rod assembly is subjected to load, it can convert the horizontal force into its own tension or compression through internal mechanical balance, thus eliminating the horizontal force. The prefabricated building module hoisting equipment of the present invention has an ingenious structure, which can reduce the horizontal force on the hoisting equipment during movement through the coordinated movement of the pulley system and the lifting group; and eliminate the horizontal force through the internal mechanical balance of the horizontal tie rod assembly, preventing the hoisting equipment from deflecting and deforming due to the horizontal force, thereby improving the safety performance of the hoisting equipment.

[0043] The prefabricated building module hoisting equipment according to embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0044] According to an embodiment of the present invention, a prefabricated building module hoisting equipment includes a horizontally arranged crossbeam tie rod assembly 10. Both ends of the crossbeam tie rod assembly 10 are connected to a vertical support assembly 40 via a first connecting portion 20 and a second connecting portion 30, respectively. The vertical support assembly 40 provides support for the crossbeam tie rod assembly 10. The height of the vertical support assembly 40 can be increased or decreased according to on-site construction needs to adapt to the required construction height range. A movable pulley block 50 is provided at the bottom of the vertical support assembly 40, which can move on the ground to move the entire hoisting equipment. A lifting assembly 60, which can move horizontally along the crossbeam tie rod assembly 10, is provided at the bottom of the crossbeam tie rod assembly 10. The lifting assembly 60 is used to lift building modules. The horizontal movement of the lifting assembly 60 along the crossbeam tie rod assembly 10 allows for precise control of the building module's position. When subjected to load, the crossbeam tie rod assembly 10 can convert the horizontal force into its own tension or compression through internal mechanical balance, thereby eliminating the horizontal force.
[0045] In other words, the movement of the building module mainly relies on the movement of the pulley block 50 to drive the overall movement of the hoisting equipment, and the horizontal movement of the lifting assembly 60 along the crossbeam tie rod assembly 10. However, when a luffing jib tower crane is used as the hoisting equipment, the tower base remains stationary, and the movement is accomplished solely by the rotation of the jib relative to the tower base. This results in a larger horizontal force on the hoisting equipment. Relying on the pulley block 50 to drive the overall movement of the hoisting equipment, and the horizontal movement of the lifting assembly 60 along the crossbeam tie rod assembly 10, can reduce the horizontal force on the hoisting equipment during the movement.
[0046] The structure of the crossbeam tie rod assembly 10 can be a simply supported tie rod arch system. When the building module is hoisted and moved, the crossbeam tie rod assembly 10 will be subjected to a certain horizontal force. The crossbeam tie rod assembly 10 uses its own structure to transfer and decompose the horizontal load, and finally converts it into its own tension or compression, thereby eliminating the horizontal force.
[0047] According to an embodiment of the prefabricated building module hoisting equipment, vertical support components 40 are connected to both ends of the horizontal tie rod assembly 10 via a first connecting part 20 and a second connecting part 30, respectively. A movable pulley block 50 is provided at the bottom of the vertical support component 40. A lifting assembly 60, capable of horizontal movement along the horizontal tie rod assembly 10, is provided at the bottom of the horizontal tie rod assembly 10. The lifting assembly 60 is used to lift the building module. The movement of the hoisting equipment is achieved by the pulley block 50 and the horizontal movement of the lifting assembly 60 along the horizontal tie rod assembly 10, thereby reducing the horizontal force on the hoisting equipment during movement. Simultaneously, when the horizontal tie rod assembly 10 is subjected to load, it can convert the horizontal force into tension or compression through its internal mechanical balance, thus eliminating the horizontal force.
[0048] According to one embodiment of the present invention, the crossbeam tie rod assembly 10 includes a horizontally arranged main beam 11, and end crossbeams 12 are provided vertically in the horizontal direction at both ends of the main beam 11. The ends of the two end crossbeams 12 on the same side are connected by an arc-shaped arch rib 13. Two arch ribs 13 are formed on both sides of the end crossbeams 12. Vertically parallel hangers 14 are provided between the arch ribs 13 and the main beam 11 at intervals. Tie rods 15 parallel to the main beam 11 are provided between the two end crossbeams 12, and tie rods 15 are connected to the end crossbeams 12.
[0049] In other words, the crossbeam tie rod assembly 10 includes a horizontally arranged main beam 11 located at the bottom of the crossbeam tie rod assembly. The lifting assembly 60 is connected to the crossbeam tie rod assembly 10 via the main beam 11 and can move horizontally along the main beam 11. Both ends of the main beam 11 are vertically provided with end crossbeams 12 in the horizontal direction. Multiple main beams 11 can be arranged between the two end crossbeams 12, depending on the length and design requirements of the crossbeam tie rod assembly 10, to enhance its strength. Two arc-shaped arch ribs 13 are connected to the ends of the two end crossbeams 12, with each end of the arch rib 13 connected to the end of the two end crossbeams 12 on the same side. Vertically parallel lifting rods 14 are spaced between the arch ribs 13 and the main beam 11; the length of the lifting rods 14 varies depending on their position between the arch ribs 13 and the main beam 11. A tie rod 15, parallel to the main beam 11, is provided between the two end crossbeams 12 and connected to the end crossbeams 12.
[0050] The clear span (i.e., horizontal span dimension) of the crossbeam tie rod assembly 10 can be set according to the layout requirements of the building to be constructed. After the prefabricated building module hoisting equipment loads the building module, it is lifted to a certain height (the bottom of the building module is higher than the top of the existing building). Then, by controlling the movement of the pulley block 50 and the horizontal position of the hoisting group 60 on the main beam 11, the building module is transported to the location to be installed.
[0051] When the prefabricated building module hoisting equipment moves and lifts building modules, it is subjected to load forces. The hoisting assembly 60 transfers the load to the main beam 11, the main beam 11 transfers the load to the suspender 14, and the suspender 14 transfers the load to the arch rib 13. After the load is transferred to the arch rib 13, the arch rib 13 converts these loads into axial compression and shear force. Under the action of its own curvature, the arch rib 13 decomposes the vertical load into horizontal thrust and vertical reaction force. The vertical reaction force is transferred to the vertical support assembly 40 through the first connection 20 or the second connection 30 at the arch rib 13. The horizontal thrust is transferred to the tie rod 15 through the end crossbeam 12. The tie rod 15, as a longitudinal member in the crossbeam tie rod assembly 10 used to resist structural deformation and provide stability, ultimately converts the horizontal force into tension or compression of the tie rod 15, which depends on its axial stiffness to bear the tension or compression.
[0052] Therefore, in the prefabricated building module hoisting equipment according to the present invention, when hoisting building modules, the crossbeam tie rod assembly 10 can, under load, convert the horizontal force into the tension or compression of the tie rod 15 through its internal mechanical balance, thereby eliminating the horizontal force. Thus, the first connecting part 20 and the second connecting part 30 only transmit the vertical load to the vertical support assembly 40, which then transmits the vertical load to the ground via the pulley block 50. In the prefabricated building module hoisting equipment of this embodiment, the crossbeam tie rod assembly 10 can convert the horizontal force into the tension or compression of the tie rod 15 through internal mechanical balance, preventing the prefabricated building module hoisting equipment from deflection and deformation, effectively ensuring the lifespan of the hoisting equipment and construction safety.
[0053] According to one embodiment of the present invention, the crossbeam tie rod assembly 10 further includes a tie beam 16, and the position where the hanger 14 is joined with the main beam 11 forms a first connection point 141, and the tie beam 16 connects two oppositely arranged first connection points 141.
[0054] In other words, such as Figure 2 As shown, the tie beam 16 is located at the bottom of the crossbeam tie rod assembly 10. The position where the hanger 14 connects to the main beam 11 forms a first connection point 141, and multiple hangers 14 form multiple first connection points 141 between themselves and the main beam 11. Among them, the connection points between a pair of hangers 14 at opposite positions of the two arch ribs 13 and the main beam 11 form two oppositely arranged first connection points 141, and the tie beam 16 connects the above two first connection points 141. When the load is transferred from the main beam 11 to the hanger 14, part of the load can be transferred from the main beam 11 to the hanger 14 through the tie beam 16, improving the load transfer efficiency from the main beam 11 to the hanger 14. At the same time, it also enhances the structural strength of the bottom of the crossbeam tie rod assembly 10.
[0055] According to one embodiment of the present invention, the crossbeam tie rod assembly 10 further includes a cross brace 17, and the position where the hanger 14 and the arch rib 13 are joined forms a second connection point 142, and the cross brace 17 connects two oppositely arranged second connection points 142.
[0056] In other words, such as Figure 2 As shown, the cross brace 17 is positioned between two arch ribs 13. The connection point between the hanger 14 and the arch rib 13 forms a second connection point 142. Multiple hangers 14 form multiple second connection points 142 with the arch ribs 13. Specifically, the connection points between a pair of hangers 14 at opposite positions on the two arch ribs 13 form two oppositely positioned second connection points 142, and the cross brace 17 connects these two second connection points 142. The cross brace 17 can increase the structural strength of the arch ribs 13. Especially when the clear span of the cross brace assembly 10 is long, the cross brace 17 can ensure that the arch ribs 13 do not deform linearly, ensure that the load is quickly transferred on the arch ribs 13, and improve the overall strength of the cross brace assembly 10.
[0057] According to one embodiment of the present invention, the first connecting part 20 includes, from top to bottom, a top plate 21, a first central shaft 22, a bottom plate 23, and an anti-drop rod 24; the top surface of the top plate 21 is fixedly connected to the bottom surface of the end crossbeam 12; the bottom surface of the top plate 21 is fixedly connected to the top surface of the first central shaft 22; the bottom of the first central shaft 22 is cylindrical, and the bottom plate 23 is provided with a through circular hole 231, through which the first central shaft 22 passes and is fixed at the bottom of the bottom plate 23 by the anti-drop rod 24; the circular hole 231 constrains the displacement of the first central shaft 22 in the horizontal direction.
[0058] In other words, such as Figure 4 , Figure 5 As shown, the first connecting part 20 includes, from top to bottom, a top plate 21, a first central shaft 22, a bottom plate 23, and an anti-detachment rod 24. The top surface of the top plate 21 is fixedly connected to the bottom surface of the end beam 12, preferably by welding. The bottom surface of the top plate 21 is fixedly connected to the top surface of the first central shaft 22 as a whole, preferably by welding. The bottom of the first central shaft 22 is cylindrical. The bottom plate 23 has a through hole 231. The first central shaft 22 passes through the hole 231 and is fixed at the bottom of the bottom plate 23 by the anti-detachment rod 24. The end of the first central shaft 22 is preferably welded or bolted to the anti-detachment rod 24 to prevent the first central shaft 22 from detaching upward from the bottom plate 23. The diameter of the cylindrical end of the first central shaft 22 matches the diameter of the hole 231, so that the hole 231 restricts the horizontal displacement of the first central shaft 22. The bottom surface of the bottom plate 23 is fixedly connected to the top surface of the vertical support assembly 40.
[0059] According to one embodiment of the present invention, the second connecting part 30 includes, from top to bottom, a top plate 21, a second central shaft 32, a bottom plate 23, and an anti-drop rod 24; the top surface of the top plate 21 is fixedly connected to the bottom surface of the end crossbeam 12; the bottom surface of the top plate 21 is fixedly connected to the top surface of the second central shaft 32; the bottom of the second central shaft 32 is cylindrical, and the bottom plate 23 is provided with a through circular hole 231, through which the second central shaft 32 passes and is fixed at the bottom of the bottom plate 23 by the anti-drop rod 24; the circular hole 231 and the second central shaft 32 are clearance-fitted in the horizontal direction.
[0060] In other words, such as Figure 6 , Figure 7As shown, the second connecting part 30 includes, from top to bottom, a top plate 21, a second central shaft 32, a bottom plate 23, and an anti-detachment rod 24. The top surface of the top plate 21 is fixedly connected to the bottom surface of the end beam 12, preferably by welding. The bottom surface of the top plate 21 is fixedly connected to the top surface of the second central shaft 32 as a whole, preferably by welding. The bottom of the second central shaft 32 is cylindrical. The bottom plate 23 has a through hole 231 through which the second central shaft 32 passes. The second central shaft 32 is fixed at the bottom of the bottom plate 23 by the anti-detachment rod 24. The end of the second central shaft 32 is preferably welded or bolted to the anti-detachment rod 24 to prevent the second central shaft 32 from detaching from the bottom plate 23 upwards. The bottom surface of the bottom plate 23 is fixedly connected to the top surface of the vertical support assembly 40. The diameter of the cylindrical end of the second central shaft 32 is smaller than the diameter of the hole 231, allowing horizontal displacement between the second central shaft 32 and the bottom plate 23. The horizontal displacement between the second central shaft 32 and the base plate 23 is allowed to facilitate the deformation required when hoisting the building module, and at the same time to avoid transmitting a large horizontal force to the vertical support component 40 due to slight deviations when the pulley block 50 moves synchronously.
[0061] Thus, the crossbeam tie rod assembly 10, composed of the main beam 11, end crossbeams 12, arch ribs 13, hangers 14, and tie rods 15, together with the first connecting part 20 and the second connecting part 30, forms a simply supported tie rod arch system. This system, through the main beam 11, end crossbeams 12, arch ribs 13, hangers 14, and tie rods 15, forms a self-balancing mechanical system. During the hoisting of building modules, the bending and compressive strength of the simply supported tie rod arch system is fully utilized. The tie rod 15, as a key component, bears the horizontal force transmitted by the arch ribs 13 and converts it into its own tension or compression. In this way, the horizontal force that would originally be borne by the vertical support assembly 40 is canceled out by the tie rod 15, thereby eliminating the horizontal force. This ensures that the first connecting part 20 and the second connecting part 30 do not generate horizontal forces, and the vertical support assembly 40 only bears vertical forces, with virtually no horizontal shear force. This prevents the vertical support assembly 40 from deflecting during the hoisting of building modules. This force transmission mechanism makes full use of the performance of each component and its materials, greatly increasing the lifting weight, thereby increasing the weight of the building module and reducing the amount of on-site splicing work.
[0062] In some specific embodiments of the present invention, the lifting assembly 60 includes an electric hoist 61 that can move on the main beam 11. The electric hoist 61 is connected to the sling 62 and provides traction force to the sling 62. The tail end of the sling 62 is provided with a hook 63.
[0063] In other words, such as Figure 1 , Figure 11As shown, the lifting assembly 60 includes an electric hoist 61, a sling 62, and a hook 63. The electric hoist 61 can move on the main beam 11, and the sling 62 connects the electric hoist 61 and the hook 63. The building module is connected to the lifting assembly 60 via the hook 63. The electric hoist 61 provides traction force to the sling 62 to drive the lifting and lowering of the building module. When the crossbeam tie rod assembly 10 bears the load transmitted by the electric hoist 61 through the main beam 11, its clear span is significantly increased compared to the traditional beam structure, and the clear span of the lifting equipment is also greatly increased. The clear span of the lifting equipment and the height of the vertical support assembly 40 can be increased or decreased as needed, thereby facilitating the lifting of the building module to the target position within the clear span of the crossbeam tie rod assembly 10 and the height of the vertical support assembly 40.
[0064] In some specific embodiments of the present invention, the electric hoists 61 are a group, and each hook 63 is provided with a balance hoisting group 64 consisting of a hoisting rope 641 and a balance beam 642.
[0065] In other words, such as Figure 1 , Figure 11 As shown, to better balance the forces on the building modules during hoisting and to better lift larger or heavier modules, the electric hoists 61 can be configured as a group or more. Furthermore, each hook 63 can be equipped with a balancing assembly 64 consisting of a lifting rope 641 and a balancing beam 642. Multiple hooks can be installed on the balancing assembly 64 as lifting points, allowing for the selection of appropriate stress points based on the size and weight of the building module. This avoids damage to the building module due to uneven stress caused by single-point or two-point stress.
[0066] In some specific embodiments of the present invention, the vertical support assembly 40 consists of a vertical rod 41, a horizontal rod 42, and a diagonal rod 43.
[0067] In other words, the vertical support assembly 40 is fixed together by a vertical rod 41, a horizontal rod 42, and a diagonal rod 43, preferably by welding. The vertical support assembly 40 consists of several segments in the vertical direction, and its height is set according to the height requirements of the building to be constructed, sufficient to meet the height requirements for safe vertical hoisting. Simultaneously, for ease of observation, a height-adjustable control room 80 can be installed on the vertical support assembly 40. The height of the control room 80 is adjusted according to the hoisting height to better observe and control the hoisting process.
[0068] In some specific embodiments of the present invention, a lateral support portion 70 is also included. The lateral support portion 70 extends obliquely upward from both ends of the pulley block 50 and converges to the vertical support assembly 40, forming a triangular structure with the pulley block 50 and the vertical support assembly 40.
[0069] In other words, such as Figure 9As shown, a lateral support 70 is provided between the vertical support assembly 40 and the pulley block 50, forming a triangular structure with the pulley block 50 and the vertical support assembly 40. The lateral support 70 provides stable support during equipment movement and hoisting, ensuring operational safety and reliability. By providing additional lateral support, the lateral support 70 effectively prevents the hoisting equipment from tilting or swaying during movement and hoisting, reducing the occurrence of accidents. This not only improves the efficiency of hoisting and movement operations but also ensures the safety of operators and equipment.
[0070] According to the prefabricated building module hoisting equipment of the present invention, vertical support components 40 are connected to both ends of the horizontal tie rod assembly 10 via a first connecting part 20 and a second connecting part 30, respectively. A movable pulley block 50 is provided at the bottom of the vertical support component 40. A lifting assembly 60, capable of horizontal movement along the horizontal tie rod assembly 10, is provided at the bottom of the horizontal tie rod assembly 10. The lifting assembly 60 is used to lift the building module. The movement of the hoisting equipment is achieved by the pulley block 50 and the horizontal movement of the lifting assembly 60 along the horizontal tie rod assembly 10, thereby reducing the horizontal force on the hoisting equipment during movement. Simultaneously, when the horizontal tie rod assembly 10 is subjected to load, it can convert the horizontal force into its own tension or compression through internal mechanical balance, thus eliminating the horizontal force.
[0071] Of course, those skilled in the art can understand and implement other structures and working principles of prefabricated building module hoisting equipment, and will not elaborate further in this invention.
[0072] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
