[0002] In the traditional process of lifting prefabricated beams and slabs, steel cables or slings are usually used for single lifting, which is not only inefficient but also has potential safety hazards. In view of this problem, although some prefabricated beam and slab integral lifting equipment has been developed, its structure is complex, the operation is difficult, and it cannot adapt to prefabricated beams and slabs of various sizes and shapes. Therefore, a new type of prefabricated beam and slab integral lifting equipment is needed to improve at least one of the problems in the prior art. Utility Model Content

[0004] The embodiment of the utility model is achieved as follows:

[0005] In a first aspect, the utility model provides a steel tube prefabricated beam and slab integral hoisting truss, comprising:

[0006] A lifting ring, a base, a first lifting mechanism and a second lifting mechanism, wherein the lifting ring is installed on the top of the base; the base has a first side surface, a second side surface, a third side surface and a fourth side surface connected end to end in sequence, the first side surface and the third side surface are opposite to each other, and the second side surface and the fourth side surface are opposite to each other; the first lifting mechanism includes a first suspension rod and a second suspension rod, one end of the first suspension rod is rotatably matched with the first side surface, and one end of the second suspension rod is rotatably matched with the third side surface; the second lifting mechanism includes a third suspension rod and a fourth suspension rod, the third suspension rod is rotatably matched with the second side surface, and the fourth suspension rod is rotatably matched with the fourth side surface; the first suspension rod, the second suspension rod, the third suspension rod and the fourth suspension rod cooperate together to lift the precast beam slab.

[0007] In an optional embodiment, the first suspension rod and the base are rotatably matched via a first ball joint structure.

[0008] Based on the above scheme, after the first hanger is clamped with the side of the precast beam, when the lifting equipment is used to connect with the lifting ring and lift the precast beam, the first hanger is driven to adaptively rotate relative to the base under the action of the gravity of the precast beam, so that the first hanger and the side of the precast beam are clamped more firmly, realizing the adaptive adjustment of the shape of the first hanger, with a wide range of use and high safety.

[0009] In an optional embodiment, the second suspension rod is rotatably matched with the base via a second ball joint structure.

[0010] Based on the above scheme, after the second hanger is clamped with the side of the precast beam, when the lifting equipment is used to connect with the lifting ring and lift the precast beam, the second hanger is driven to adaptively rotate relative to the base under the action of the gravity of the precast beam, so that the second hanger and the side of the precast beam are clamped more firmly, realizing the adaptive adjustment of the shape of the second hanger, with a wide range of use and high safety.

[0011] In an optional embodiment, the third suspension rod is rotatably matched with the base via a third ball joint structure.

[0012] Based on the above scheme, after the third hanger is clamped with the side of the precast beam, when the lifting equipment is used to connect with the lifting ring and lift the precast beam, the third hanger is driven to adaptively rotate relative to the base under the action of the gravity of the precast beam, so that the third hanger and the side of the precast beam are clamped more firmly, realizing the adaptive adjustment of the shape of the third hanger, with a wide range of use and high safety.

[0013] In an optional embodiment, the fourth suspension rod is rotatably matched with the base via a fourth ball joint structure.

[0014] Based on the above scheme, after the fourth hanger is clamped with the side of the precast beam, when the lifting equipment is used to connect with the lifting ring and lift the precast beam, the fourth hanger is driven to adaptively rotate relative to the base under the action of the gravity of the precast beam, so that the fourth hanger and the side of the precast beam are more firmly clamped, realizing the adaptive adjustment of the shape of the fourth hanger, which has a wide range of use and high safety.

[0015] In an optional embodiment, at least one of the first, second, third and fourth hangers is provided with a claw at the end away from the base, the claw having an inner arc surface forming a groove and an outer side surface opposite to the inner arc surface, and a roller is installed on the outer side surface.

[0016] Based on the above scheme, the clamping claw is firmly connected with the side of the precast beam plate, thereby improving the safety during the process of hoisting the precast beam plate. At the same time, when the first, second, third and fourth hangers are used to clamp the precast beam plate, the first, second, third and fourth hangers are first located above the upper plate surface of the precast beam plate. During the descent of the hoisting equipment, the entire hoisting truss is lowered, and the rollers on the clamping claws are in contact with the upper plate surface. As the descent height continues to increase, the first, second, third and fourth hangers are opened outward. Since the rollers are in contact with the upper plate surface, the friction is small and the opening is convenient. Until the first, second, third and fourth hangers are opened to the side of the precast beam plate, they continue to descend a certain distance, and then the clamping claws are lifted to clamp the clamping claws with the side of the precast beam plate, and then the precast beam plate can be hoisted.

[0017] In an optional embodiment, an elastic layer is provided on the outer surface of the roller.

[0018] Based on the above solution, the elastic layer is in contact with the upper plate surface and is not easy to scratch the prefabricated beam plate.

[0019] In an optional embodiment, the elastic layer is configured as a rubber layer or a silicone layer.

[0020] Based on the above solution, the elastic layer has a simple structure and low cost.

[0021] In an optional embodiment, the first suspension rod and the second suspension rod are both configured as telescopic rods.

[0022] Based on the above scheme, the lengths of the first hanger rod and the second hanger rod can be adjusted accordingly according to prefabricated beams and slabs of different sizes, and the scope of use is wide.

[0023] In an optional embodiment, the third suspension rod and the fourth suspension rod are both configured as telescopic rods.

[0024] Based on the above scheme, the lengths of the third hanger and the fourth hanger can be adjusted accordingly according to prefabricated beams and slabs of different sizes, and the scope of use is wide.

[0025] The beneficial effects of the embodiments of the utility model are:

[0026] In summary, the steel tube prefabricated beam and slab integral lifting truss provided in this embodiment can be connected with the lifting ring by lifting equipment such as a crane during operation, and the entire lifting truss can be lifted so that it is located directly above the prefabricated beam and slab to be lifted. Then, the lifting truss is lowered, and the first suspension rod, the second suspension rod, the third suspension rod and the fourth suspension rod are in contact with the upper plate surface of the prefabricated beam and slab, and as the lowering height increases, the first suspension rod, the second suspension rod, the third suspension rod and the fourth suspension rod can all move to the edges of the first side surface, the second side surface, the third side surface and the fourth side surface of the prefabricated beam and slab. When the lowering height is appropriate, the first suspension rod corresponds to the first side surface, the second suspension rod corresponds to the third side surface, the third suspension rod corresponds to the second side surface, and the fourth suspension rod corresponds to the fourth side surface. Then, the lifting ring is raised by the lifting equipment, thereby driving the first suspension rod, the second suspension rod, the third suspension rod and the fourth suspension rod to rise, and the first suspension rod, the second suspension rod, the third suspension rod and the fourth suspension rod all hook the edge of the prefabricated beam and slab, thereby achieving lifting. The heavier the precast beam, the tighter the fit between the first, second, third and fourth hangers and the precast beam, and the more stable the hoisting. According to the different sizes of the precast beam, the first, second, third and fourth hangers can be connected with the side of the precast beam to achieve hoisting, and have a wide range of uses.

[0039] In view of this, the designer provides a steel tube prefabricated beam and slab integral lifting truss, which is easy to operate, has a wide range of uses and low cost.

[0040] Please combine Figure 1-Figure 2 In this embodiment, the steel tube prefabricated beam and slab integral lifting truss includes a lifting ring 100, a base 200, a first lifting mechanism 300 and a second lifting mechanism 400. The lifting ring 100 is installed on the top of the base 200; the base 200 has a first side 210, a second side 220, a third side 230 and a fourth side 240 connected end to end in sequence, the first side 210 and the third side 230 are opposite to each other, and the second side 220 and the fourth side 240 are opposite to each other; the first lifting mechanism 300 includes a first hanging rod 310 and a second hanging rod 320, one end of the first hanging rod 310 is rotatably matched with the first side 210, and one end of the second hanging rod 320 is rotatably matched with the third side 230; the second lifting mechanism 400 includes a third hanging rod 410 and a fourth hanging rod 420, the third hanging rod 410 is rotatably matched with the second side 220, and the fourth hanging rod 420 is rotatably matched with the fourth side 240; the first hanging rod 310, the second hanging rod 320, the third hanging rod 410 and the fourth hanging rod 420 cooperate together to lift the precast beam slab.

[0041] Based on the above, the working principle of the steel tube prefabricated beam and slab integral hoisting truss provided in this embodiment is as follows:

[0042] During operation, a lifting device such as a crane can be used to connect the lifting ring 100 to lift the entire lifting truss so that it is located directly above the precast beam to be lifted. Then, the lifting truss is lowered, and the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 are in contact with the upper plate surface of the precast beam, and as the lowering height increases, the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 can all move to the edges of the first side 210, the second side 220, the third side 230 and the fourth side 240 of the precast beam. When the lowering height is appropriate, the first suspension rod 310 is located at the first side 210, the second side 220, the third side 230 and the fourth side 240 of the precast beam. 10, the second suspension rod 320 corresponds to the third side 230, the third suspension rod 410 corresponds to the second side 220, and the fourth suspension rod 420 corresponds to the fourth side 240, and then the lifting equipment is used to raise the lifting ring 100, thereby driving the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 to rise, and the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 all hook the edge of the precast beam slab, thereby achieving lifting. The heavier the precast beam slab, the tighter the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 cooperate with the precast beam slab, and the more stable the lifting. According to the different sizes of the precast beam slab, the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 can all be connected with the side of the precast beam slab to achieve lifting, and have a wide range of uses.

[0043] The following embodiments illustrate the details of the steel tubular prefabricated beam-slab integral lifting truss provided in the present application by way of examples.

[0044] In this embodiment, the first suspension rod 310 and the base 200 are optionally rotatably matched through a first ball joint structure. After the first suspension rod 310 is clamped with the side of the precast beam, when the precast beam is connected to the lifting ring 100 by the lifting equipment and the precast beam is lifted, the first suspension rod 310 is driven to rotate adaptively relative to the base 200 under the gravity of the precast beam, so that the first suspension rod 310 and the side of the precast beam are clamped more firmly, realizing the adaptive adjustment of the shape of the first suspension rod 310, with a wide range of use and high safety.

[0045] In this embodiment, the second suspension rod 320 and the base 200 are optionally rotatably matched through a second ball joint structure. After the second suspension rod 320 is clamped with the side of the precast beam, when the precast beam is connected to the lifting ring 100 by the lifting equipment and the precast beam is lifted, the second suspension rod 320 is driven to rotate adaptively relative to the base 200 under the gravity of the precast beam, so that the second suspension rod 320 and the side of the precast beam are clamped more firmly, realizing the adaptive adjustment of the shape of the second suspension rod 320, with a wide range of use and high safety.

[0046] In this embodiment, the third suspension rod 410 and the base 200 are optionally rotatably matched through a third ball joint structure. After the third suspension rod 410 is clamped with the side of the precast beam, when the precast beam is connected to the lifting ring 100 by the lifting equipment and the precast beam is lifted, the third suspension rod 410 is driven to rotate adaptively relative to the base 200 under the gravity of the precast beam, so that the third suspension rod 410 and the side of the precast beam are clamped more firmly, realizing the adaptive adjustment of the shape of the third suspension rod 410, with a wide range of use and high safety.

[0047] In this embodiment, the fourth suspension rod 420 is optionally rotatably matched with the base 200 through a fourth ball joint structure. After the fourth suspension rod 420 is clamped with the side of the precast beam, when the precast beam is lifted by the lifting equipment connected to the lifting ring 100, the fourth suspension rod 420 is driven to rotate adaptively relative to the base 200 under the gravity of the precast beam, so that the fourth suspension rod 420 is more firmly clamped with the side of the precast beam, and the shape of the fourth suspension rod 420 is adaptively adjusted, which has a wide range of uses and high safety.

[0048] In this embodiment, optionally, a claw 330 is provided at the end away from the base 200 of at least one of the first hanger 310, the second hanger 320, the third hanger 410 and the fourth hanger 420, and the claw 330 has an inner arc surface forming a groove and an outer side surface opposite to the inner arc surface, and a roller 340 is installed on the outer side surface.

[0049] With such a design, the clamping claw 330 is firmly clamped with the side of the precast beam plate, thereby improving the safety during the process of hoisting the precast beam plate. At the same time, when the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 are clamped with the precast beam plate, the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 are firstly positioned above the upper plate surface of the precast beam plate. During the descent of the hoisting equipment, the entire hoisting truss is lowered, and the roller 340 on the clamping claw 330 is in contact with the upper plate surface. As the descent height continues to increase, the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 are opened outwards. Since the roller 340 is in contact with the upper plate surface, the friction is small and the opening is convenient. Until the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 are opened until the claw 330 is located at the side of the precast beam slab, they continue to descend a certain distance, and then lift the claw 330 so that the claw 330 is engaged with the side of the precast beam slab, and then the precast beam slab can be hoisted.

[0050] It should be understood that the first suspension rod 310 , the second suspension rod 320 , the third suspension rod 410 and the fourth suspension rod 420 may all be provided with a clamping claw 330 , and the clamping claw 330 may all be provided with a roller 340 .

[0051] Furthermore, an elastic layer is provided on the outer surface of the roller 340. The elastic layer is in contact with the upper plate surface and is not easy to scratch the prefabricated beam plate.

[0052] It should be understood that the elastic layer can be set as a rubber layer or a silicone layer. The elastic layer has a simple structure and low cost.

[0053] In this embodiment, optionally, the first suspension rod 310 and the second suspension rod 320 are both configured as telescopic rods. The lengths of the first suspension rod 310 and the second suspension rod 320 can be adjusted accordingly according to prefabricated beams of different sizes, and the application range is wide.

[0054] In this embodiment, optionally, the third suspension rod 410 and the fourth suspension rod 420 are both configured as telescopic rods. The lengths of the third suspension rod 410 and the fourth suspension rod 420 can be adjusted accordingly according to prefabricated beams of different sizes, and the scope of use is wide.

[0055] It should be noted that the structures of the first hanger 310, the second hanger 320, the third hanger 410 and the fourth hanger 420 can be set to be the same. For example, taking the first hanger 310 as an example, the first hanger 310 includes a first rod and a second rod. The first rod is provided with a sliding hole, and the second rod is inserted into the sliding hole. The first rod is provided with a locking pin, and the second rod is provided with a plurality of adjustment holes. The plurality of adjustment holes are arranged at intervals in the length direction of the second rod. The locking pin can be plugged and matched with one of the plurality of adjustment holes, so as to realize the adjustment of the combined position of the first rod and the second rod, and finally realize the adjustment of the length of the first hanger 310.

[0056] In addition, in some embodiments, the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 can all be rotatably matched with the base 200 through a rotating shaft. In this way, by replacing the ball joint with a rotating shaft, the first suspension rod 310, the second suspension rod 320, the third suspension rod 410 and the fourth suspension rod 420 can also cooperate to clamp the prefabricated beam plate. That is, the first suspension rod 310 is rotatably connected to the base 200 through the first rotating shaft, the second suspension rod 320 is rotatably connected to the base 200 through the second rotating shaft, the third suspension rod 410 is rotatably connected to the base 200 through the third rotating shaft, and the fourth suspension rod 420 is rotatably connected to the base 200 through the fourth rotating shaft. The first rotating shaft is parallel to the second rotating shaft, the third rotating shaft is parallel to the fourth rotating shaft, and the first rotating shaft is perpendicular to the third rotating shaft.
