Description

Technical Field

[0001] The utility model relates to the field of hoisting equipment, in particular to a hoisting beam. Background Art

[0002] When lifting heavy objects with a lifting beam, vertical traction balanced lifting is usually used, that is, two symmetrical holes are set on the lifting beam, and the two holes are connected to the heavy objects below through shackles and lifting ropes, so that during the lifting process, the lifting ropes on both sides always remain in the vertical direction. Compared with oblique lifting, vertical traction balanced lifting can make the heavy objects overall stable during the lifting operation, and the lifting ropes on both sides are more evenly stressed and bear less load, avoiding problems such as large swings or overturning of the heavy objects in the air, thereby ensuring the life safety of on-site workers. However, at the lifting site, it is often necessary to lift a variety of heavy objects of different sizes, shapes, and weight distributions, which brings the following problems:

[0003] First, due to the differences in the position and spacing of the lifting points on the surfaces of the heavy objects, the positions of the holes on the lifting beam and the connected shackles cannot be adjusted. Therefore, in many cases, the lifting rope is inclined rather than vertical during lifting, which causes the lifting rope to be subjected to a greater load and increases safety hazards.

[0004] Second, for eccentric heavy objects, it is necessary to ensure that the center of the hook, the center of the beam, and the center of gravity of the heavy object of the lifting equipment are on the same plumb line. Otherwise, during the lifting process, once the heavy object leaves the ground, it is easy to swing violently in the direction of the horizontal force, endangering the life safety of the on-site workers. Therefore, the trial lifting method is often used on site instead of one-time lifting. That is, when the heavy object is off the ground, the on-site workers repeatedly adjust the position of the lifting point on the surface of the heavy object to ensure that the force of the lifting ropes on both sides is in the vertical direction, and at the same time meet the requirements of the three centers being on the same plumb line; until the balance is achieved, the heavy object is officially lifted from the ground; because the position of the holes on the beam and the position of the connected shackles are fixed, if the lifting tilt phenomenon still exists after repeatedly adjusting the position of the lifting point on the surface of the heavy object, it is necessary to replace the beam with different specifications and models. This leads to low efficiency of the lifting work, which in turn delays the construction period and increases the construction cost. Utility Model Content

[0063] In this embodiment, by setting the traction member 33 as a traction rope, the possibility of the traction member 33 being structurally damaged due to excessive shear force of the shackle 2 can be reduced.

[0064] In this embodiment, by setting the driving device 31 as a motor, the first pulley 32 can be driven by electricity.

[0065] In this embodiment, the beam body is provided to include four steel plates 11 and a connecting member 12 of corresponding shapes. The four steel plates 11 are respectively fixed to one side of the connecting member 12; the four first pulleys 32 are all clamped between the two steel plates 11 located on the same side of the connecting member 12, and are respectively located near the ends of the steel plates 11. A relatively simple structure can be used to prevent on-site construction workers from contacting the first pulley 32 when approaching the suspension beam, thereby ensuring the personal safety of on-site construction workers.

[0066] Please refer to Figure 6 In this embodiment, the specific structure of the fastening cylinder 35 is as follows: it includes a cross-shaped cylindrical portion and a connecting portion; the cylindrical portion is fixedly connected to the traction member 33, and the fixed connection position must meet the requirement that the fastener 35 can move within the length range of the steel plate member 11, and the inner surface of the cylindrical portion is provided with a straight thread to increase the friction with the surface of the traction member 33; the two ends of the connecting portion are symmetrically welded to the two sides of the shackle 2, so that the shackle 2 is evenly stressed. Of course, in other embodiments, other fastening cylinder structures that meet the requirements of the site can also be set.

[0067] In this embodiment, the material of the fastening tube 35 is stainless steel. Of course, in other embodiments, other lightweight materials may be selected to prevent the overall downward deflection of the traction member 33 from being too large.

[0068] In this embodiment, by setting a driving device 31 fixed to the outside of the steel plate 11, and two driving devices 31 close to the connecting member 12 and two driving devices 31 far from the connecting member 12 are located on different sides of the beam body, the weight of the suspension beam can be evenly distributed.

[0069] In this embodiment, by setting up the buckle moving device including two control parts (not shown in the figure), the two control parts respectively control the rotation speed of the two driving devices 31 located on the same side of the connecting member 12 to be the same, so that the two first pulleys 32 that roll up the same traction member 33 can maintain synchronous operation, thereby avoiding the traction member 33 being overly stretched or overly relaxed due to the asynchronous operation of the two first pulleys 32.

[0070] In this embodiment, the shackle moving device also includes a first rotating shaft 36, and the four first rotating shafts 36 are respectively connected to the corresponding driving devices 31 and the first pulley 32.

[0075] In this embodiment, the length of the steel plate 11 is L, the height is H, and the structural parameters are further set as:

[0076] The total length of the traction rope is greater than or equal to 3L to avoid limiting the moving area of ​​the shackle;

[0077] The groove depth of the first pulley 32 must be such that after the traction rope of 1.5L is wound and stacked, it still does not exceed the outermost circular contour edge of the first pulley 32 to prevent the traction rope from falling out of the groove;

[0078] The groove width D1 of the first pulley 32, the groove width D2 of the second pulley 37, and the groove depth of the second pulley 37 are all slightly larger than the diameter of the traction rope to stabilize the traction rope;

[0079] The sum of the motor diameter and twice the diameter of the nut 43 is less than H;

[0080] The spacing between the steel plate members 11 is slightly greater than the thickness of the thicker pulley between the first pulley 32 and the second pulley 37;

[0081] Six holes are formed on the surface of the single steel plate 11, namely, two axial holes, which are arranged symmetrically, and four bolt holes, which are circumferentially distributed at equal intervals outside the single axial hole, to fix the first pulley 32 and the motor.

[0082] In this embodiment, the support rod 34 is fixed (welded in this embodiment) to the lower end of the steel plate 11 by two lifting ears 42, and the overall length of the support rod 34 and the lifting ears 42 is less than the difference between L and twice the outer diameter of the first pulley.

[0087] S3. Adjust the position of the hanging beam so that the center of the hook, the center of the hanging beam, and the initial center of gravity of the heavy object are on the same plumb line;

[0088] S4, adjusting the position of the shackle 2 (e.g., the on-site construction personnel send a signal to the controller through the remote control to control the operation of the motor, so as to move the shackle 2 along the length direction A of the beam body by winding and pulling the two ends of the traction rope), so that the two shackles 2 are respectively located directly above the heavy object lifting points;

[0089] S5, connect the corresponding shackle 2 and the heavy object lifting point with a lifting rope;

[0090] S6. Lift the heavy object to a lower height;
