Description

Technical Field

[0001] The utility model relates to the technical field of transfer equipment, and in particular to a transfer sling deflection compensation device, a transfer sling and transfer equipment. Background Art

[0002] In the prior art, the utility model patent with publication number CN211594841U proposes a transfer vehicle, including a chassis, a leg mechanism, a first slewing mechanism, a pitch mechanism, a main telescopic arm mechanism, a variable amplitude mechanism and a special transfer sling, wherein the special transfer sling is used to connect with the hanging parts and can fix or release the hanging parts. The special transfer sling has some defects during use, for example: the special transfer sling lacks a deflection compensation mechanism, that is, during the transfer sling process, since the hanging parts themselves have a certain weight, the transfer sling bearing device connected to the transfer sling will produce a certain degree of deflection deformation, thereby causing the relative posture of the transfer sling and the hanging parts to change during the lifting process, thereby bringing additional lateral loads to the transfer sling and the hanging parts, and thus easily causing damage to the transfer sling and the hanging parts.

[0003] Patent document CN218708685U discloses a transfer sling deflection compensation device, which uses a lateral force sensor to detect the deformation deflection of the transfer sling structure connected to the load-bearing transfer sling in real time, and uses a second drive mechanism to control the position of the connecting frame to make adaptive adjustments, thereby compensating for the deflection deformation of the transfer sling load-bearing device. The structure of this transfer sling deflection compensation device is relatively complex, and both signal detection and deflection compensation have hysteresis. Therefore, the present application provides a transfer sling deflection compensation device with a simple structure and real-time compensation. Utility Model Content

[0004] In view of the above problems in the prior art, the present application proposes a transfer sling deflection compensation device, a transfer sling and a transfer equipment, which can compensate for the deflection deformation of the transfer sling bearing device in real time.

[0005] The utility model provides a transfer sling deflection compensation device, the transfer sling deflection compensation device comprises a transfer sling body, the transfer sling body comprises a rotating platform and a connecting frame, the connecting frame can be hinged with the transfer sling carrying device, the top surface of the rotating platform is provided with at least one horizontal guide rail groove extending along the deflection deformation direction of the transfer sling carrying device, a roller group is rotatably installed in the horizontal guide rail groove, a clamping plate is provided on the lower side of the connecting frame, the clamping plate can extend into the horizontal guide rail groove and the roller group is in rolling contact with the upper surface of the clamping plate, a telescopic driving member is provided at the end of the horizontal guide rail groove, the telescopic end of the telescopic driving member is connected to the connecting frame, the telescopic end of the telescopic driving member can move with the connecting frame, or drive the connecting frame to move.

[0006] As a further improvement of the above technical solution:

[0007] The above-mentioned transfer sling deflection compensation device, further, the horizontal guide groove and the clamping plate are both inverted T-shaped structures, two groups of roller groups are installed side by side in the horizontal guide groove, and the two groups of roller groups are in rolling contact with the upper surfaces on both sides of the inverted T-shaped clamping plate respectively.

[0008] The above-mentioned transfer sling deflection compensation device further has the following features: the telescopic driving member is a double-rod oil cylinder, and one of the piston rods of the double-rod oil cylinder is hinged to the connecting frame.

[0009] Another aspect of the utility model provides a transfer sling, which includes the transfer sling deflection compensation device as described above.

[0010] On the other hand, the utility model provides a transfer device, which includes the transfer sling as mentioned above.

[0011] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the utility model can be achieved.

[0012] The utility model provides a transfer sling deflection compensation device, transfer sling and transfer equipment, which have at least the following beneficial effects compared with the prior art: when the transfer sling body lifts the object, the electro-hydraulic control system sets the control mode of the telescopic drive member to the passive mode, and the telescopic drive member does not output force. When the transfer sling bearing device generates deflection due to the load, the head of the transfer sling bearing device will generate relative displacement with the object, and the connecting frame is hinged with the head of the transfer sling bearing device through a pin shaft, the rotating platform is connected with the object, and the roller group can be rotatably installed in the horizontal guide groove, and the lower side of the roller group is in rolling contact with the upper surface of the clamping plate, so the friction resistance of the connecting frame and the rotating platform is very small when the relative movement is small. Therefore, when the head of the transfer sling bearing device moves relative to the object, the telescopic end of the telescopic drive member moves with the connecting frame, which will drive the connecting frame to move along the horizontal guide groove of the rotating platform, thereby eliminating the structural stress or position translation after the transfer sling bearing device is lifted due to the deflection. When the transfer spreader is fully loaded, the electro-hydraulic control system sets the control mode of the telescopic drive member to the active mode. The telescopic end of the telescopic drive member moves with the driving connecting frame, thereby making the final correction to the relative position of the transfer spreader load-bearing device and the load. It also ensures that the relative position of the slewing platform and the connecting frame remains unchanged during the transfer of the load, thereby ensuring that the spatial position of the load remains unchanged.

[0029] The embodiment of the utility model provides a transfer sling deflection compensation device 100, which can compensate for the deflection deformation of the transfer sling bearing device in real time.

[0030] See also Figure 1 and Figure 2The transfer sling deflection compensation device 100 provided by the embodiment of the utility model comprises a transfer sling body, the transfer sling body comprises a rotating platform 110 and a connecting frame 120, the connecting frame 120 can be hinged with the transfer sling carrying device, the top surface of the rotating platform 110 is provided with at least one horizontal guide groove 111 extending along the deflection deformation direction of the transfer sling carrying device, a roller group 130 is rotatably installed in the horizontal guide groove 111, a clamping plate 121 is provided on the lower side of the connecting frame 120, the clamping plate 121 can extend into the horizontal guide groove 111 and the roller group 130 is in rolling contact with the upper surface of the clamping plate 121, a telescopic driving member 140 is provided at the end of the horizontal guide groove 111, the telescopic end of the telescopic driving member 140 is connected to the connecting frame 120, and the telescopic end of the telescopic driving member 140 can move with the connecting frame 120, or drive the connecting frame 120 to move.

[0031] When the transfer sling body lifts the object, the electro-hydraulic control system sets the control mode of the telescopic drive member 140 to the passive mode, and the telescopic drive member 140 does not output force. When the transfer sling bearing device generates deflection due to the load, the head of the transfer sling bearing device will produce relative displacement with the object, and the connecting frame 120 is hinged with the head of the transfer sling bearing device through a pin shaft, the rotary platform 110 is connected with the object, and the roller group 130 can be rotatably installed in the horizontal guide groove 111. The lower side of the roller group 130 is in rolling contact with the upper surface of the clamping plate 121, so the friction resistance of the connecting frame 120 and the rotary platform 110 is very small when the relative movement. Therefore, when the head of the transfer sling bearing device moves relative to the object, the telescopic end of the telescopic drive member 140 moves with the connecting frame 120, which will drive the connecting frame 120 to move along the horizontal guide groove 111 of the rotary platform 110, thereby eliminating the structural stress or position translation after the transfer sling bearing device is lifted due to the deflection. When the transfer sling is fully loaded, the electro-hydraulic control system sets the control mode of the telescopic drive member 140 to the active mode, and the telescopic end of the telescopic drive member 140 moves along with the driving connecting frame 120, so as to make the final correction to the relative position between the transfer sling carrying device and the load, and ensure that the relative position of the rotating platform 110 and the connecting frame 120 remains unchanged during the transfer of the load, thereby ensuring that the spatial position of the load remains unchanged.

[0032] The transfer sling deflection compensation device 100 provided in the embodiment of the utility model is specifically described in conjunction with Figure 3 and Figure 4, the horizontal guide groove 111 and the clamping plate 121 are both inverted T-shaped structures, and two groups of roller groups 130 are rotatably installed side by side in the horizontal guide groove 111, and the two groups of roller groups 130 are in rolling contact with the upper surfaces on both sides of the inverted T-shaped clamping plate 121 respectively. The clamping plate 121 of the inverted T-shaped structure cooperates with the horizontal guide groove 111 of the inverted T-shaped structure, so that the force between the clamping plate 121 and the horizontal guide groove 111 can be more balanced, ensuring that the clamping plate 121 can move smoothly along the horizontal guide groove 111. The telescopic drive member 140 is a double-rod oil cylinder, and one of the piston rods of the double-rod oil cylinder is hinged to the connecting frame 120. Both side walls of the horizontal guide groove 111 are provided with mounting holes 112, and the two ends of the central support shaft of the roller group 130 are respectively limited and installed in the mounting holes 112 of the two side walls.
