Description

[0002] In the field of construction, hoisting equipment is widely used to improve construction efficiency and shorten construction period. With the development of technology and social needs, prefabricated buildings are becoming more and more popular. The prefabricated building modules are transported to the designated location through hoisting equipment for rapid assembly and construction, which can greatly reduce the time of on-site construction.

[0003] As a common lifting equipment in prefabricated building construction, boom-type tower cranes have the advantages of large lifting capacity, flexible operation and wide coverage. However, during the lifting process, as the building module is rotated horizontally, it will generate horizontal force on the lifting equipment, which may easily cause the lifting equipment to produce corresponding vertical deflection and deformation, affecting the service life of the lifting equipment, and posing certain safety hazards. In addition, as the length of the lifting equipment boom increases, its lifting weight gradually decreases, limiting the lifting weight and range of the building module, requiring more building modules to be divided during prefabrication, resulting in an increase in on-site splicing parts, significantly reducing the efficiency of prefabricated building construction.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The following describes in detail the assembled building module lifting equipment according to an embodiment of the present invention with reference to the accompanying drawings.

[0044] According to the embodiment of the present invention, the prefabricated building module hoisting equipment includes a horizontally arranged horizontal tie rod assembly 10, and the two ends of the horizontal tie rod assembly 10 are respectively connected to the vertical support assembly 40 through the first connection part 20 and the second connection part 30. The vertical support assembly 40 provides support force for the horizontal tie rod assembly 10, and the height of the vertical support member 40 can be increased or decreased according to the needs of on-site construction to meet the needs of the construction height range. A movable pulley block 50 is provided at the bottom of the vertical support assembly 40, and the pulley block 50 can move on the ground to drive the entire hoisting equipment to move; a lifting group 60 that can move horizontally along the horizontal tie rod assembly 10 is provided at the bottom of the horizontal tie rod assembly 10, and the lifting group 60 is used to lift the building module. The lifting group 60 moves horizontally along the horizontal tie rod assembly 10 to accurately control the moving position of the building module; when the horizontal tie rod assembly 10 is subjected to load, it can convert the horizontal force into its own tension or pressure through its own internal mechanical balance to eliminate the horizontal force.

[0045] In other words, the movement of the building module is mainly achieved by the movement of the pulley block 50 to drive the overall movement of the lifting equipment, and the horizontal movement of the lifting group 60 along the horizontal frame tie rod assembly 10. When the jib tower crane is used as the lifting equipment, the tower base does not move, and it is only achieved by the rotation of the boom relative to the tower base, which causes the lifting equipment to be subjected to a large horizontal force. The method of relying on the pulley block 50 to drive the overall movement of the lifting equipment, and the lifting group 60 to move horizontally along the horizontal frame tie rod assembly 10 can reduce the horizontal force on the lifting equipment during the movement.

[0046] The structure of the cross-frame tie rod assembly 10 can be a simply supported tie-arch system structure. When the cross-frame tie rod assembly 10 is hoisted and moved with the building module, the cross-frame tie rod assembly 10 itself will be subjected to a certain horizontal force. The cross-frame tie rod assembly 10 uses its own structure to transfer and decompose the horizontal load, and finally converts it into its own tension or pressure, thereby eliminating the horizontal force.

[0047] According to the prefabricated building module hoisting equipment of the embodiment of the present invention, the two ends of the horizontal frame tie rod assembly 10 are connected to the vertical support assembly 40 through the first connection part 20 and the second connection part 30 respectively, and the bottom of the vertical support assembly 40 is provided with a movable pulley group 50. The bottom of the horizontal frame tie rod assembly 10 is provided with a lifting group 60 that can move horizontally along the horizontal frame tie rod assembly 10, and the lifting group 60 is used to lift the building module. The building module is moved by driving the lifting equipment to move by the pulley group 50 and the lifting group 60 to move horizontally along the horizontal frame tie rod assembly 10, thereby reducing the horizontal force on the lifting equipment during the movement. At the same time, when the horizontal frame tie rod assembly 10 is subjected to the load, it can convert the horizontal force into its own tension or pressure through its own internal mechanical balance, thereby eliminating the horizontal force.

[0048] According to one embodiment of the present invention, a cross-frame tie rod assembly 10 includes a horizontally arranged main beam 11, and end cross beams 12 are vertically arranged in the horizontal direction at both ends of the left and right ends of the main beam 11. The ends of the two end cross beams 12 on the same side are connected by an arc-shaped arch rib 13, and two arch ribs 13 are formed on both sides of the end cross beam 12. Suspension rods 14 parallel to each other in the vertical direction are arranged between the arch ribs 13 and the main beam 11; a tie rod 15 parallel to the main beam 11 is arranged between the two end cross beams 12, and the tie rod 15 is connected to the end cross beam 12.

[0049] In other words, the cross-frame tie rod assembly 10 includes a horizontally arranged main beam 11, which is located at the bottom of the cross-frame tie rod assembly. The lifting group 60 is connected to the cross-frame tie rod assembly 10 through the main beam 11 and can move along the main beam 11 in its horizontal direction. The left and right ends of the main beam 11 are vertically provided with end cross beams 12 in the horizontal direction. Multiple main beams 11 can be arranged between the two end cross beams 12, which is specifically considered according to the length and design requirements of the cross-frame tie rod assembly 10 to enhance the strength of the cross-frame tie rod assembly 10. The ends of the two end cross beams 12 are connected with two arc-shaped arch ribs 13, and the two ends of the arch ribs 13 are respectively connected to the ends of the same side of the two end cross beams 12. Between the arch ribs 13 and the main beam 11, there are intervals of suspension rods 14 parallel to each other in the vertical direction; the lengths of the suspension rods 14 at different positions are different due to the different positions between the arch ribs 13 and the main beam 11. Between the two end cross beams 12, there are tie rods 15 parallel to the main beam 11, and the tie rods 15 are connected to the end cross beams 12.

[0050] The clear span (i.e., horizontal span size) of the horizontal tie rod assembly 10 can be set according to the plan layout of the building to be built. 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 built building), and then the building module is transported to the location where it needs to be installed by controlling the movement of the pulley block 50 and the horizontal position of the hoisting group 60 on the main beam 11.

[0051] When the prefabricated building module hoisting equipment moves and hoists the building module, it will be subjected to the force of the load. The hoisting group 60 transfers the load to the main beam 11, the main beam 11 transfers the load to the suspension rod 14, and the suspension rod 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 pressure 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 transmitted to the vertical support assembly 40 through the first connection part 20 or the second connection part 30 at the arch rib 13. The horizontal thrust is transmitted to the tie rod 15 through the end cross beam 12. The tie rod 15 is a longitudinal member in the cross-frame tie rod assembly 10 for resisting structural deformation and providing stability. Finally, the horizontal force is converted into tension or pressure of the tie rod 15, and the tension or pressure is withstand by its axial stiffness.

[0052] Therefore, according to the prefabricated building module hoisting equipment of the present invention, when lifting the building module, the horizontal frame tie rod assembly 10 can, when subjected to the load, convert the horizontal force into the tension or pressure of the tie rod 15 itself through its own internal mechanical balance, thereby eliminating the horizontal force. In this way, the first connecting part 20 and the second connecting part 30 only transfer the vertical load to the vertical support assembly 40, and the vertical support assembly 40 transfers the vertical load to the ground through the pulley block 50. In the prefabricated building module hoisting equipment of the embodiment of the present invention, the horizontal frame tie rod assembly 10 can convert the horizontal force into the tension or pressure of the tie rod 15 itself through internal mechanical balance, thereby preventing the prefabricated building module hoisting equipment from deflection and deformation, and effectively ensuring the service life of the hoisting equipment and construction safety.

[0053] According to one embodiment of the present invention, the cross-frame tie rod assembly 10 further includes a tie beam 16 , and the position where the hanger rod 14 is combined with the main beam 11 forms a first connection point 141 , and the tie beam 16 connects two first connection points 141 that are oppositely arranged.

[0054] That is to say, Figure 2 As shown, the tie beam 16 is arranged at the bottom of the cross-frame tie rod assembly 10, and the position where the hanger 14 is combined with the main beam 11 forms a first connection point 141, and multiple first connection points 141 are formed between multiple hangers 14 and the main beam 11. Among them, the combination of a pair of hangers 14 and the main beam 11 at the relative positions of the two arch ribs 13 forms two first connection points 141 arranged oppositely, and the tie beam 16 connects the above two first connection points 141. When the load is transferred to the hanger 14 through the main beam 11, part of the load can be transferred from the main beam 11 to the hanger 14 through the tie beam 16, thereby improving the efficiency of load transfer from the main beam 11 to the hanger 14. At the same time, the structural strength of the bottom of the cross-frame tie rod assembly 10 is also enhanced.

[0055] According to one embodiment of the present invention, the cross-frame tie rod assembly 10 further includes a cross brace 17 , and the position where the hanger rod 14 is combined with the arch rib 13 forms a second connection point 142 , and the cross brace 17 connects two second connection points 142 that are oppositely arranged.

[0056] In other words, Figure 2 As shown, the cross brace 17 is arranged between two arch ribs 13, and the position where the hanger 14 and the arch rib 13 are combined forms a second connection point 142, and multiple second connection points 142 are formed between multiple hangers 14 and the arch rib 13. Among them, the combination of a pair of hangers 14 and the arch rib 13 at the relative position of the two arch ribs 13 forms two second connection points 142 arranged oppositely, and the cross brace 17 connects the above two second connection points 142. The cross brace 17 can increase the structural strength of the arch rib 13, especially when the clear span of the cross-frame tie rod assembly 10 is long, the cross brace 17 can ensure that the arch rib 13 does not deform linearly, ensure that the load is quickly transmitted on the arch rib 13, and improve the overall strength of the cross-frame tie rod assembly 10.

[0057] According to one embodiment of the present invention, the first connecting portion 20 includes a top plate 21, a first central axis 22, a bottom plate 23 and an anti-falling rod 24 from top to bottom; the top surface of the top plate 21 is fixedly connected to the bottom surface of the end cross beam 12; the bottom surface of the top plate 21 is fixedly connected to the top surface of the first central axis 22; the bottom of the first central axis 22 is cylindrical, and a penetrating circular hole 231 is provided on the bottom plate 23, the first central axis 22 passes through the circular hole 231, and is fixed by the anti-falling rod 24 at the bottom of the bottom plate 23; the circular hole 231 constrains the horizontal displacement of the first central axis 22.

[0058] In other words, Figure 4 , Figure 5 As shown, the first connecting part 20 includes a top plate 21, a first central axis 22, a bottom plate 23 and an anti-drop rod 24 from top to bottom; the top surface of the top plate 21 is fixedly connected to the bottom surface of the end cross beam 12, preferably by welding. The bottom surface of the top plate 21 is fixedly connected to the top surface of the first central axis 22 to form a whole, preferably by welding. The bottom of the first central axis 22 is cylindrical, and a through circular hole 231 is provided on the bottom plate 23. The first central axis 22 passes through the circular hole 231 and is fixed by the anti-drop rod 24 at the bottom of the bottom plate 23. The end position of the first central axis 22 is preferably welded or bolted to the anti-drop rod 24 to protect the first central axis 22 from detaching upward from the bottom plate 23; the diameter of the cylindrical end of the first central axis 22 matches the diameter of the circular hole 231, so that the circular hole 231 constrains the displacement of the first central axis 22 in the horizontal direction. 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 portion 30 includes a top plate 21, a second center axis 32, a bottom plate 23 and an anti-falling rod 24 from top to bottom; the top surface of the top plate 21 is fixedly connected to the bottom surface of the end cross beam 12; the bottom surface of the top plate 21 is fixedly connected to the top surface of the second center axis 32; the bottom of the second center axis 32 is cylindrical, and a penetrating circular hole 231 is provided on the bottom plate 23, the second center axis 32 passes through the circular hole 231, and is fixed by the anti-falling rod 24 at the bottom of the bottom plate 23; the circular hole 231 and the second center axis 32 are clearance-matched in the horizontal direction.

[0060] In other words, Figure 6 , Figure 7As shown, the second connecting part 30 includes a top plate 21, a second central axis 32, a bottom plate 23 and an anti-drop rod 24 from top to bottom; the top surface of the top plate 21 is fixedly connected to the bottom surface of the end cross beam 12, preferably by welding; the bottom surface of the top plate 21 is fixedly connected to the top surface of the second central axis 32 to form a whole, preferably by welding; the bottom of the second central axis 32 is cylindrical, and a through circular hole 231 is provided on the bottom plate 23. The second central axis 32 passes through the circular hole 231 and is fixed by the anti-drop rod 24 at the bottom of the bottom plate 23. The end position of the second central axis 32 is preferably welded or bolted to the anti-drop rod 24 to protect the second central axis 32 from detaching upward from the bottom plate 23; 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 axis 32 is smaller than the diameter of the circular hole 231, so that horizontal displacement can occur between the second central axis 32 and the bottom plate 23. The horizontal displacement between the second center group 32 and the bottom plate 23 is allowed to facilitate the deformation requirement when hoisting the building module, and to meet the slight deviation when the pulley group 50 moves synchronously, so as to avoid transmitting a large horizontal force to the vertical support assembly 40.

[0061] Thus, the cross-frame tie rod assembly 10 composed of the main beam 11, the end cross beam 12, the arch rib 13, the hanger 14, and the tie rod 15, together with the first connection part 20 and the second connection part 30, together form a simply supported tie rod arch system, which forms a self-balancing mechanical system through the main beam 11, the end cross beam 12, the arch rib 13, the hanger 14, and the tie rod 15. When hoisting the building module, the bending resistance and compression resistance of the simply supported tie rod arch system are fully utilized. The tie rod 15, as a key component, is used to bear the horizontal force transmitted by the arch rib 13 and convert it into the tension or pressure of the tie rod 15 itself. In this way, the horizontal force that originally needs to be borne by the vertical support assembly 40 is offset by the tie rod 15, thereby achieving the elimination of the horizontal force. The first connection part 20 and the second connection part 30 do not generate horizontal forces, and the vertical support assembly 40 only bears vertical forces, and basically has no horizontal shear force, which can avoid the deflection displacement of the vertical support assembly 40 when hoisting the building module. This force transmission mechanism makes full use of the performance of each component and its materials, greatly improving the lifting weight, thereby increasing the weight of the building module and reducing the workload of on-site splicing.

[0062] In some specific embodiments of the present invention, the lifting group 60 includes an electric hoist 61 that can move on the main beam 11. The electric hoist 61 is connected to a sling 62 and provides traction for the sling 62. A hook 63 is provided at the tail end of the sling 62.

[0063] In other words, Figure 1 , Fig.11As shown, the lifting group 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 group 60 through the hook 63. The electric hoist 61 provides traction for the sling 62 to drive the lifting of the building module. When the cross-frame tie rod assembly 10 is subjected to the load transmitted by the electric hoist 61 through the main beam 11, its clear span is significantly improved compared with 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, so as to facilitate the lifting of the building module to the target position within the clear span of the cross-frame tie rod assembly 10 and the height of the vertical support assembly 40.

[0064] In some specific embodiments of the present invention, the electric hoist 61 is a group, and each hook 63 is provided with a balance hanging group 64 consisting of a hanging rope 641 and a balance beam 642 .

[0065] In other words, Figure 1 , Fig.11 As shown, in order to better balance the force of the building module during hoisting and better hoist the building module with larger volume or heavier weight, the electric hoist 61 is set as a group or even more, and each hook 63 can be provided with a balance hanging group 64 consisting of a hanging rope 641 and a balance beam 642. Multiple hooks can be set on the balance group 64 as lifting points, so that according to the volume and weight of the building module, a suitable force point can be selected to connect with the lifting point, so as to avoid single-point force or two-point force, which may cause the building module to be damaged due to uneven force.

[0066] In some specific embodiments of the present invention, the vertical support assembly 40 is composed of a vertical stem 41 , a horizontal rod 42 and an inclined rod 43 .

[0067] In other words, the vertical support assembly 40 is fixed by the vertical stem 41, the horizontal rod 42 and the diagonal rod 43, preferably welded. The vertical support assembly 40 is composed of a plurality of segments in the vertical direction, and its height is set according to the height of the building to be built, and the height of the vertical safe hoisting is sufficient. At the same time, for the convenience of observation, a control room 80 that can be raised and lowered can be set on the vertical support assembly 40. The height of the control room 80 is raised and lowered according to the hoisting height, so as to better observe and control the hoisting process.

[0068] In some specific embodiments of the present invention, a lateral support portion 70 is further 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 to form a triangular structure with the pulley block 50 and the vertical support assembly 40.

[0069] In other words, Fig. 9As shown, a lateral support portion 70 is provided between the vertical support assembly 40 and the pulley block 50, and the lateral support portion 70 forms a triangular structure with the pulley block 50 and the vertical support assembly 40. The lateral support portion 70 plays a role of stable support during the movement and hoisting of the equipment to ensure the safety and reliability of the operation. By providing additional lateral support force, the lateral support portion 70 can effectively prevent the hoisting equipment from tilting or shaking during movement and hoisting, thereby reducing the occurrence of accidents. This not only improves the efficiency of hoisting and moving operations, but also ensures the safety of operators and equipment.

[0070] According to the prefabricated building module hoisting equipment of the present invention, the two ends of the horizontal frame tie rod assembly 10 are connected to the vertical support assembly 40 through the first connection part 20 and the second connection part 30 respectively, and the bottom of the vertical support assembly 40 is provided with a movable pulley group 50. The bottom of the horizontal frame tie rod assembly 10 is provided with a lifting group 60 that can move horizontally along the horizontal frame tie rod assembly 10, and the lifting group 60 is used to lift the building module. The building module is moved by driving the lifting equipment through the pulley group 50 and the lifting group 60 moves horizontally along the horizontal frame tie rod assembly 10, reducing the horizontal force on the lifting equipment during the movement. At the same time, when the horizontal frame tie rod assembly 10 is subjected to the load, it can convert the horizontal force into its own tension or pressure through its own internal mechanical balance to eliminate the horizontal force.

[0071] Of course, for those skilled in the art, other structures and working principles of the prefabricated building module lifting equipment are understandable and achievable, and will not be described in detail in the present invention.

[0072] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
