Examples

As shown in fig. 1, the present embodiment provides a lifting posture adjusting mechanism, which includes a balance beam 1, a rotating module 2, a connecting frame 3, and three lifting rods 4. The specific development is as follows: the balance beam 1 adopts a T-shaped structure, and the bottoms of the three lifting rods 4 are respectively hinged with three ends of the T-shaped top surface of the balance beam 1 to form a triangular structure. The middle part of compensating beam 1 is the ring type, sets up rotation module 2 below the position of ring shape, and link 3 hangs and installs the below at rotation module 2. As shown in fig. 2, the lifting rod 4 is hinged to the balance beam 1 by a spherical hinge 5, and a pin load sensor 6 is further disposed on the spherical hinge 5 to measure the load at the spherical hinge 5. The spherical hinge 5 is structurally matched with the three lifting beams in triangular distribution to realize the angle adjustment of the full degree of freedom of the balance beam 1, and the three lifting rods 4 can synchronously drive or asynchronously drive the balance beam 1 to adjust the posture.

As shown in figures 3 and 4, the rotary module 2 adopts a nested structure of the rotary frame 22 and the rotary support 23, and then the rotary support 23 and the driving motor 21 are meshed and connected by the gear 24, so that the structure is simple and reliable, and the stability is good. The specific development is as follows: the rotation module 2 includes a driving motor 21, a rotation frame 22, and a rotation support 23. The rotary support 23 is cylindrical and is fixed to the lower portion of the ring shape of the balance beam 1 by bolts. The rotating frame 22 is sleeved on the rotating support 23 and can rotate around the rotating support 23. The sleeving mode is that a first annular groove is arranged on the inner ring of the rotating frame 22, a second annular groove corresponding to the first annular groove is arranged on the outer ring of the rotating support 23, the two annular grooves are in butt joint to form an annular space with a circular section, and balls are arranged in the annular space. The structure can have better bearing capacity under the condition of meeting the rotation requirement. An installation groove is arranged on the balance beam 1, the driving motor 21 is fixed in the installation groove, and an output shaft of the driving motor is vertically arranged downwards. An output shaft of the driving motor 21 is connected with a gear 24, and an annular rack 25 is fixed on an outer ring of the rotating frame 22 and is used for meshing with the gear 24 on the output shaft. Thus, when the driving motor 21 rotates, the driving motor 21 drives the ring-shaped rack 25 via the gear 24 to rotate the rotating frame 22, and the link 3 fixed to the rotating frame 22 also rotates.

As shown in fig. 1, the link frame 3 is fixed below the rotating frame 22 by bolts. A gripping clip is fixed on the connecting frame 3. When the mechanism moves, the three lifting rods 4 can synchronously drive or asynchronously drive the balance beam 1, and the rotating module 2 drives the connecting frame 3 to rotate, so that the connecting frame 3 can actively adjust the posture and the angle in a large range. From this, fixed grabbing on the link 3 presss from both sides can realize snatching the multi-angle of girder steel, satisfies the platform deck and builds the demand.

In summary, the present embodiment provides a dedicated three-fulcrum adjustable lifting posture adjusting mechanism for overcoming the defects in the prior art. But also synchronous drive through three lifter 4 individual drive, through the motion lift of UNICOM and the gesture and the angle of adjustment link 3. Meanwhile, when the lifting posture adjusting mechanism is used on the assembly portal frame, and the grabbing clamp is arranged on the connecting frame 3, the steel beam piece with a certain horizontal inclination angle can be grabbed from the ground transport vehicle.

In this embodiment, because the three lifting rods 4 are distributed in a triangular shape, and the three fulcrums jointly define a plane, the same workpiece can be stably lifted. Simultaneously, there is a lifter 4 for triangle-shaped distribution, can allow the great skew of work piece focus: when the center of gravity is in the triangular area, the three lifting rods 4 are all pulled; as shown in fig. 5 and 6, when the center of gravity is outside the triangular region, both sets of lift pins 4 are in tension and one set of lift pins 4 are in compression.

In this embodiment, a pin load sensor 6 is disposed on a ball hinge 5 used between the lifting rod 4 and the balance beam 1, so that the stress of each hinge point can be measured, the total load can be calculated, and the gravity center position of the load can be calculated. The specific calculation method is the conventional calculation process, so the expansion is not carried out.

In this embodiment, the same girder steel work piece of three lifter 4 common lifting, girder steel weight can be great and 4 drive powers of lifter are less.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the principles of this invention without the use of inventive faculty. Therefore, the technical solutions that can be obtained by logical analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention by those skilled in the art should be within the scope of protection defined by the claims.
