Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a balance beam structure and hoisting components. Background Technology

[0002] Balance beams are frequently used in lifting operations. A balance beam is a commonly used sling that can balance the force of two or more slings during hoisting. It can withstand the horizontal component force caused by the inclination of the slings, reduce the pressure on the load during hoisting, shorten the length of the slings, reduce the lifting height of the pulleys, and shorten the time for binding the load. It is safe and convenient to use. However, the parameters of traditional balance beams are usually determined according to the diameter, size and weight of the equipment during manufacturing.

[0003] However, the balance beam is made of pipes, plates and profiles welded together. After the manufacturing is completed, its strength grade and length are determined. Therefore, it can only be used for one type of equipment. When hoisting other equipment, it is necessary to remake the corresponding balance beam according to the different hoisting objects. The scope of application is narrow, and the use of balance beams with different models can easily cause damage to the equipment. Utility Model Content

[0004] The main purpose of this utility model is to propose a balance beam structure and hoisting assembly, which aims to improve the existing balance beams, which have a narrow range of applications and are prone to equipment damage due to the different applicable models.

[0005] To achieve the above objectives, the present invention proposes a balance beam structure and hoisting assembly, comprising:

[0006] The beam structure includes multiple connecting beam segments spaced laterally, each of the connecting beam segments being detachably connected to at least one adjacent connecting end;

[0007] Two lifting structures are arranged at a distance along the lateral direction. The two lifting structures are respectively connected to two connecting beam segments arranged laterally away from each other. Each lifting structure has two connecting parts arranged at a distance along the vertical direction. Both connecting parts are rotatably arranged. One connecting part is used to connect to the hook through a connecting rope, and the other connecting part is used to connect to the lifting lug of the equipment through a connecting rope.

[0008] In one embodiment, each of the lifting structures includes:

[0009] The installation part is connected to one of the connecting beam segments;

[0010] Two clamping parts are provided at intervals along the longitudinal or transverse direction on the mounting part, and the two clamping parts are used to clamp the two connecting parts together.

[0011] In one embodiment, the two connecting portions include a first connecting portion disposed above the other connecting portion. The first connecting portion is rotatably disposed between the two clamping portions along a longitudinally extending axis. The first connecting portion is used to connect a hook via the connecting rope.

[0012] In one embodiment, the two connecting portions further include a second connecting portion disposed below the other connecting portion, the second connecting portion comprising:

[0013] A first connector, rotatably disposed between the two clamping portions along a longitudinally extending axis; and,

[0014] The second connector is rotatably connected to the first connector along a laterally extending axis, and the second connector is used to connect the lifting lug of the equipment via the connecting rope.

[0015] In one embodiment, each of the connecting portions includes a connecting wheel.

[0016] In one embodiment, the plurality of connecting beam segments include:

[0017] Two connecting end beams are spaced apart laterally, and each of the two connecting end beams connects to one of the two hoisting structures; and...

[0018] An intermediate beam is disposed between the two connecting end beams, and the two ends of the intermediate beam are detachably connected to the two connecting end beams respectively in the transverse direction.

[0019] In one embodiment, each of the lifting structures is movably mounted laterally on the corresponding connecting end beam.

[0020] In one embodiment, the balance beam structure further includes two locking structures, each of which includes a locking part and a mating part. One of the locking part and the mating part is located on the corresponding hoisting structure, and the other is located on the corresponding connecting end beam. The locking part and the mating part are used to connect and restrict the corresponding hoisting structure from moving laterally.

[0021] This utility model also proposes a hoisting assembly, comprising:

[0022] A balance beam structure, the balance beam structure being as described above; and,

[0023] Four connecting ropes are respectively sleeved on the four connecting parts, wherein two of the connecting ropes are used to connect the hook to the two connecting parts above, and the other two connecting ropes are used to connect the lifting lugs of the equipment to the two connecting parts below.

[0024] In one embodiment, the connecting rope includes one of a steel wire rope and a connecting cloth strip.

[0025] In the technical solution of this utility model, when the balance beam structure is needed for hoisting work, the operator can respectively loop multiple connecting ropes onto the four connecting parts to connect the connecting ropes to the connecting parts, and then loop multiple connecting ropes onto the hook and the lifting lug of the equipment. At this time, the length of the multiple connecting beam segments in the lateral direction is the length of the crossbeam structure in the lateral direction. The operator can adjust the length of the crossbeam structure in the lateral direction by adjusting the number of multiple connecting beam segments or the size of each connecting beam segment, so that the length of the crossbeam structure in the lateral direction corresponds to the size of the equipment in the lateral direction. This configuration expands the application range of the balance beam structure. During hook lifting, the two lifting structures can decompose one point of force application of the hook into two laterally spaced points, ensuring the balance of the equipment during lifting. Furthermore, since the connecting part is rotatably mounted on the corresponding lifting structure, when the connecting part is under load, it can drive the connecting rope fitted onto itself to rotate, ensuring uniform force distribution on the connecting rope. Simultaneously, the transverse length of the beam structure corresponds to the transverse dimensions of the equipment, reducing the horizontal pressure on the equipment during lifting operations and lowering the risk of deformation or damage due to lateral forces. It also shortens the suspension height of the connecting rope and ensures the extension direction of the connecting ropes connecting the lifting lugs and the two connecting parts, while reducing the horizontal tension on the connecting rope and protecting it from breakage.

[0034] This invention proposes a balance beam structure and hoisting assembly. It aims to improve upon existing balance beams, which have a narrow application range and are prone to equipment damage due to inconsistencies in applicable models.

[0035] Please see Figure 1In one embodiment of this utility model, the balance beam structure 100 includes a crossbeam structure 1 and two lifting structures 2. The crossbeam structure 1 includes a plurality of connecting beam segments arranged laterally at intervals. Each connecting beam segment is detachably connected to at least one adjacent connecting end. The two lifting structures 2 are arranged laterally at intervals and are respectively connected to two connecting beam segments arranged laterally away from each other. Each lifting structure 2 has two connecting parts arranged vertically at intervals. Both connecting parts are rotatably arranged. One connecting part is used to connect to a hook via a connecting rope 200, and the other connecting part is used to connect to the lifting lug of the structure 2 to be lifted via a connecting rope 200.

[0036] In the technical solution of this utility model, when the balance beam structure 100 is needed for hoisting work, the operator can respectively loop multiple connecting ropes 200 onto the four connecting parts to connect the connecting ropes 200 to the connecting parts, and then respectively loop multiple connecting ropes 200 onto the hook and the lifting lugs of the equipment. At this time, the length of the multiple connecting beam segments in the lateral direction is the length of the crossbeam structure 1 in the lateral direction. The operator can adjust the length of the crossbeam structure 1 in the lateral direction by adjusting the number of multiple connecting beam segments or the size of each connecting beam segment, so that the length of the crossbeam structure 1 in the lateral direction corresponds to the size of the equipment in the lateral direction, which can expand the application range of the balance beam structure 100. Moreover, when the hook is lifted, the two lifting structures 2 can balance one of the forces of the hook. The point is decomposed into two horizontally spaced force points, thereby ensuring the balance of the equipment during the hoisting process. Furthermore, since the connecting part is rotatably mounted on the corresponding hoisting structure 2, when the connecting part is under force, it can drive the connecting rope 200 sleeved on itself to rotate, so as to ensure that the connecting rope 200 is evenly stressed. At the same time, the horizontal length of the beam structure 1 corresponds to the horizontal size of the equipment, which can reduce the horizontal pressure on the equipment during hoisting operations, reduce the risk of deformation or damage to the equipment due to lateral forces, and also shorten the suspension height of the connecting rope 200. It also ensures the extension direction of the connecting rope 200 connecting the lifting lugs of the equipment and the two connecting parts, while reducing the horizontal tension on the connecting rope 200, protecting the connecting rope 200 and preventing it from breaking.

[0037] It should be noted that this utility model does not limit the specific method for adjusting the length of the beam structure 1 in the lateral direction. In one embodiment of this utility model, the length of the beam structure 1 in the lateral direction can be adjusted by adjusting the number of the connecting beam segments. In another embodiment of this utility model, the length of the beam structure 1 in the lateral direction can be adjusted by adjusting the length of at least one of the connecting beam segments. In yet another embodiment of this utility model, the length of the beam structure 1 in the lateral direction can be adjusted by simultaneously adjusting the number of the connecting beam segments and the length of at least one of the connecting beam segments.

[0038] In this embodiment, the length of the beam structure 1 in the lateral direction is adjusted by adjusting the length of at least one of the connecting beam segments in the lateral direction.

[0039] In one specific embodiment of this utility model, the plurality of connecting beam segments include two connecting end beams 11 and one intermediate beam 12. The two connecting end beams are arranged laterally at intervals. The two connecting end beams 11 are respectively connected to the two hoisting structures 2. The intermediate beam 12 is located between the two connecting end beams 11, and its two ends in the lateral direction are detachably connected to the two connecting end beams 11. With this arrangement, since the two ends of the intermediate beam 12 are detachably connected to the two connecting end beams 11 in the lateral direction, when it is necessary to adjust the length of the crossbeam structure 1 in the lateral direction, the operator can disconnect the intermediate beam 12 from the two connecting end beams 11, and then replace it with another intermediate beam 12 of different length. The two ends of this intermediate beam 12 are then connected to the two connecting end beams 11 in the lateral direction, thereby achieving the purpose of adjusting the length of the crossbeam structure 1 in the lateral direction so that the length of the crossbeam structure 1 in the lateral direction is equivalent to the lateral dimension of the equipment.

[0040] When the length of the crossbeam structure 1 in the lateral direction is equivalent to the lateral dimension of the equipment, in a further embodiment of this utility model, to further calibrate the force points formed by the two lifting structures 2 and the lateral position of the equipment, each of the lifting structures 2 is movably mounted on the corresponding connecting end beam 11 in the lateral direction. With this arrangement, before the lifting operation begins, the operator can further drive the two lifting structures 2 to move laterally on the connecting end beam 11 to further accurately determine the relative position of the two force points and the equipment, reduce the lateral force component during the lifting process, and further improve the lifting quality.

[0041] It should be further explained that, to prevent the two hoisting structures 2 from shifting positions during hoisting operations and causing hoisting accidents, in a further embodiment of this utility model, the balance beam structure 100 also includes two locking structures. Each locking structure includes a locking part and a mating part. One of the locking part and the mating part is located on the corresponding hoisting structure 2, and the other is located on the corresponding connecting end beam 11. The locking part and the mating part are used to connect and restrict the lateral movement of the corresponding hoisting structure 2. With this configuration, when it is necessary to adjust the lateral position of the hoisting structure 2, the locking part and the mating part are disconnected to ensure the normal movement of the hoisting structure 2. After the adjustment is completed, the locking part connects to the mating part, thereby locking the corresponding hoisting structure 2 to the corresponding connecting end beam 11, restricting the movement of the corresponding hoisting structure 2, and ensuring the smooth progress of the hoisting operation.

[0042] It is understood that, to ensure the installation stability of the connecting parts, in one embodiment of this utility model, each of the hoisting structures 2 includes a mounting part 21 and two clamping parts 22. The mounting part 21 is connected to one of the connecting beam segments, and the two clamping parts 22 are spaced apart on the mounting part 21 longitudinally or laterally. The two clamping parts 22 are used to jointly clamp the two connecting parts. With this configuration, the mounting part 21 ensures the connection stability between the hoisting structure 2 and the connecting beam segment, and the two clamping parts 22 can clamp the two opposite ends of the connecting parts longitudinally or laterally, providing stable support for the connecting parts and ensuring their normal operation when the connecting parts are under stress.

[0043] It should be noted that the present invention does not limit the specific spacing direction of the two clamping parts 22. In one embodiment of the present invention, the two clamping parts 22 are spaced apart in the longitudinal direction. Correspondingly, the two connecting parts are rotatably arranged along the longitudinally extending axis to ensure that the normal rotation of the connecting parts is not affected when the two clamping parts 22 clamp the connecting parts. In another embodiment of the present invention, the two clamping parts 22 are spaced apart in the transverse direction. Correspondingly, the two connecting parts are rotatably arranged along the transversely extending axis to ensure that the rotation of the two connecting parts is not affected when the two clamping parts 22 clamp the connecting parts.

[0044] Specifically, in one embodiment of this utility model, the two clamping portions 22 are arranged longitudinally at intervals, and the two connecting portions include a first connecting portion 23, which is disposed above the other connecting portion. The first connecting portion 23 is rotatably disposed between the two clamping portions 22 along a longitudinally extending axis, and is used to connect the hook through the connecting rope 200. With this arrangement, since the hook is located laterally between the two first connecting portions 23, when both first connecting portions 23 of the lifting structure 2 are connected to the hook through the connecting rope 200 and are under force, both first connecting portions 23 can rotate along the longitudinally extending axis, thereby ensuring uniform force on the corresponding connecting rope 200. Furthermore, the peripheral surfaces of the two first connecting portions 23 can always press against the connecting rope 200 to ensure the stability of the connection with the connecting rope 200, preventing the first connecting portion 23 from disengaging from the connecting rope 200 during lifting, which could lead to a lifting accident.

[0045] Similarly, in another embodiment of the present invention, the two clamping portions 22 are arranged longitudinally at intervals, and the two connecting portions further include a second connecting portion 24. The second connecting portion 24 is disposed below the other connecting portion. The second connecting portion 24 includes a first connecting member 241 and a second connecting member 242. The first connecting member 241 is rotatably disposed between the two clamping portions 22 along a longitudinally extending axis, and the second connecting member 242 is rotatably connected to the first connecting member 241 along a transversely extending axis. The second connecting member 242 is used to connect the lifting lug of the device through the connecting rope 200. With this configuration, when the two connecting ropes 200 are respectively sleeved on the two second connecting members 242, and the two lifting structures 2 are under load, the two second connecting members 242 can rotate along the horizontally extending axis, thereby ensuring that the corresponding connecting ropes 200 are subjected to uniform force. At the same time, since the second connecting members 242 are connected to the first connecting members 241, if there is a difference between the length of the beam structure 1 in the horizontal direction and the size of the equipment in the horizontal direction, the two first connecting members 241 can drive the corresponding second connecting members 242 to rotate along the longitudinally extending axis, thereby adjusting the position of the two second connecting members 242 in the horizontal direction, and thus ensuring that the first connecting member 241, the second connecting member 242, the connecting ropes 200 and the lifting lugs of the equipment are on the same straight line, ensuring the stable progress of the lifting operation.

[0046] Of course, this utility model does not limit the specific structural form of the connecting part. In one embodiment of this utility model, each of the connecting parts can be configured as a bearing; in another embodiment of this utility model, each of the connecting parts includes a connecting wheel.

[0047] Specifically, in this utility model, the first connecting part 23, the first connecting member 241, and the second connecting member 242 are all configured as the connecting wheel.

[0048] This utility model also proposes a hoisting assembly 1000, which includes a balance beam structure 100 and four connecting ropes 200. The specific structure of the balance beam structure 100 is as described in the above embodiments. Since this hoisting assembly 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The four connecting ropes 200 are respectively sleeved on the four connecting parts, wherein two connecting ropes 200 are used to connect the hook to the two upper connecting parts, and the other two connecting ropes 200 are used to connect the lifting lugs of the equipment to the two lower connecting parts.

[0049] Of course, this utility model does not limit the specific structural form of the connecting rope 200, which includes either a steel wire rope or a connecting cloth strip. In one embodiment of this utility model, the connecting rope 200 is a steel wire rope; in another embodiment of this utility model, the connecting rope 200 is a connecting cloth strip.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
