Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cranes, in particular to an intelligent crane system for precise handling. BACKGROUND

[0002] In the field of industrial handling, traditional cranes such as bridge cranes and gantry cranes have long relied on steel wire rope hoisting systems to achieve material transfer in three-dimensional space. Although such devices can complete basic lifting tasks, their inherent technical limitations are increasingly evident in modern intelligent manufacturing and precision assembly applications. The flexible nature of the steel wire rope system causes the suspended object to oscillate continuously during braking and operation, requiring repeated fine-tuning by the operator to achieve precise alignment, resulting in low efficiency and a risk of collision. In particular, in industries such as automobile manufacturing and precision instrument installation that require sub-millimeter positioning accuracy, traditional cranes have difficulty meeting process requirements.

[0003] Currently, some improved cranes attempt to suppress oscillation by adding anti-sway devices such as mechanical dampers or electronic anti-sway systems, but these additional systems are often complex, costly, and have limited effectiveness. The intelligent crane described in patent document CN112499439A uses a servo control system to reduce oscillation, but its core is still based on steel wire rope transmission, which cannot fundamentally solve the problem of elastic vibration. On the other hand, the motion control of existing cranes is mostly managed in segments, lacking coordination between walking, transverse movement, and lifting actions, resulting in poor precision of complex motion trajectories. Although individual solutions use rigid chains or hydraulic cylinders instead of steel wire ropes (such as the multi-stage hydraulic lifting mechanism in CN215798395U), these designs are often bulky and lack flexibility, making it difficult to achieve intelligent operation in a compact space.

[0004] With the advancement of Industry 4.0, the workshop logistics system has higher requirements for lifting equipment: it needs to have multiple capabilities such as precise positioning, fast response, intelligent scheduling, and flexible adaptation. In particular in scenarios such as high-bay warehouses and automated production lines, cranes not only need to achieve "point-to-point" precise handling, but also need to work collaboratively with AGVs, robots, and other equipment. However, traditional cranes have low positioning accuracy and insufficient intelligence, which has become a bottleneck in the intelligent manufacturing process. Therefore, a new type of crane system is needed to break through the existing technical barriers. SUMMARY

[0022] The two walking side beams 32 are arranged in parallel, and the two ends of the walking side beam 32 are each connected with a walking wheel 33, the walking wheel 33 walks on a fixed walking track 35, and the walking track 35 is generally fixed on the column of the workshop. The walking side beam 32 is fixed with a walking motor 34, the rotating shaft of the walking motor 34 is fixed with a walking gear, and the side surface of the walking track 35 is fixed with a walking rack meshed with the walking gear, so that precise longitudinal movement is realized through the meshing of the walking gear and the walking rack.

[0023] The lifting module 1 comprises a mounting seat 12 fixed on the transverse moving vehicle 2 and a lifting vertical pipe 11 vertically sliding on the mounting seat 12, and the mounting seat 12 is fixed on the middle part of the transverse main beam 21 by bolts. The lifting vertical pipe 11 is a square pipe, a lifting rack 14 is fixed on one side surface of the lifting vertical pipe 11, and guide rails 13 are fixed on the remaining three side surfaces of the lifting vertical pipe 11. The mounting seat 12 is fixed with a sliding block matched with the guide rail 13. The mounting seat 12 is fixed with a lifting motor 15, the rotating shaft of the lifting motor 15 is fixed with a lifting gear 16, the lifting vertical pipe 11 is fixed with a lifting rack 14 meshed with the lifting gear 16, and the lower end of the lifting vertical pipe 11 is fixed with a lower connecting plate 17, and the lower connecting plate 17 is provided with a lower connecting plate connecting hole.

[0024] The lifting rack 14 is vertically arranged and fixed on one side surface of the lifting vertical pipe 11 by bolts. The upper end of the lifting vertical pipe 11 is fixed with an upper top plate 18, and the lower end surface of the upper top plate 18 and the upper end surface of the lower connecting plate 17 are both fixed with a buffer block 19, so that the upper and lower limit buffers during the lifting of the lifting vertical pipe 11 are realized.

[0025] It also comprises an adjusting vertical pipe 110 penetrating into the lower end of the lifting vertical pipe 11, as shown in the figure. Figure 7 As shown, the upper end of the outer ring of the adjusting vertical pipe 110 is fixed with an upper limiting ring 113 matched with the inner wall of the lifting vertical pipe 11, and the lower end of the inner ring of the lifting vertical pipe 11 is fixed with a lower limiting ring 114 matched with the outer wall of the adjusting vertical pipe 110. Therefore, when the adjusting vertical pipe 110 is stretched out to the longest position, the upper limiting ring 113 of the outer ring of the adjusting vertical pipe 110 is supported on the lower limiting ring 114 of the inner ring of the lifting vertical pipe 11, and the weight is supported by the lower limiting ring 114 and the upper limiting ring 113.

[0026] The lower end of the adjusting vertical pipe 110 is fixed with an adjusting connecting plate 111, and the adjusting connecting plate 111 is provided with an adjusting connecting plate connecting hole corresponding to the lower connecting plate connecting hole. The adjusting connecting plate connecting hole is used to realize the connection with the hoisting equipment, and when the adjusting vertical pipe 110 does not need to be extended, the lower connecting plate 17, the adjusting connecting plate 111 and the hoisting equipment can be integrally connected by the bolt.

[0027] The upper end of the adjusting connecting plate connecting hole is provided with a counterbore for accommodating the bolt head. When the adjusting connecting plate 111 is connected with the hoisting equipment, the bolt head of the connecting bolt is located in the counterbore, so that the lower connecting plate 17 and the adjusting connecting plate 111 can be attached.

[0028] The lifting vertical pipe 11 is provided with an electric push rod 112 for driving the adjusting vertical pipe 110 to lift. The telescopic shaft of the electric push rod 112 is arranged downward, and the upper end of the main body of the electric push rod 112 is connected to the inner wall of the lifting vertical pipe 11 through a mounting seat, so that the diameter of the electric push rod 112 is not too large.

[0029] As shown in Figure 5 , 7 The adjusting vertical pipe 110 is radially slidably connected with a plurality of supporting plug shafts 116, the supporting plug shafts 116 are four and are uniformly distributed along the circumference of the adjusting vertical pipe 110, and the lifting vertical pipe 11 is provided with plug holes 118 matched with the supporting plug shafts 116. When the adjusting vertical pipe 110 is completely retracted into the lifting vertical pipe 11, the supporting plug shafts 116 are aligned with the plug holes 118.

[0030] The telescopic shaft of the electric push rod 112 is fixed with a center block 115 located in the adjusting vertical pipe 110, the center block 115 is located at the center line position in the adjusting vertical pipe 110, the supporting plug shafts 116 are connected with the center block 115 through inclined connecting rods 117, the upper end of the connecting rod 117 is hinged with the supporting plug shaft 116, and the lower end of the connecting rod 117 is hinged with the center block 115, so that when the center block 115 moves up and down, the supporting plug shaft 116 can be driven to slide horizontally, and when the center block 115 moves upward, the supporting plug shaft 116 is driven to extend outward, so as to abut against the inner wall of the lifting vertical pipe 11 until it is inserted into the plug hole after being aligned with the plug hole.

[0031] The use method of the present application is as follows.

[0032] The hoisting equipment is fixed on the adjusting connecting plate 111 of the lifting module 1, the lifting module 1 is used to drive the hoisting equipment and the workpiece to lift, the hoisting equipment is generally a mechanical hand, a lifting hook and the like, and in working, the workpiece is clamped or lifted by the hoisting equipment. The traversing vehicle 2 is used to drive the lifting module 1, the hoisting equipment and the workpiece to move horizontally, and the traveling vehicle 3 is used to drive the traversing vehicle 2, the lifting module 1, the hoisting equipment and the workpiece to move longitudinally in the horizontal direction.

[0033] When the lifting module 1 is working, the lifting motor 15 drives the lifting gear to rotate, thereby driving the lifting vertical pipe 11 to lift through the meshing with the lifting rack, so as to realize the lifting operation of the workpiece.

[0034] Since the lifting device is fixed to the lower end surface of the adjusting connecting plate 111, when the distance between the workpiece to be lifted and the height of the lifting vertical pipe 11 is small, and the adjusting vertical pipe 110 does not need to be lengthened for a long period of time, the adjusting vertical pipe 110 can be retracted into the lifting vertical pipe 11 by the electric push rod, so that the adjusting connecting plate 111 and the lower connecting plate 17 are attached, and the three are integrally connected by the bolt passing through the lower connecting plate 17, the adjusting connecting plate 111 and the lifting device.

[0035] When the distance between the workpiece to be lifted and the height of the lifting vertical pipe 11 often changes greatly, the lifting device is only connected with the adjusting connecting plate 111, and at this time, the height adjustment of the lifting device can be realized by driving the adjusting vertical pipe 110 to lift by the electric push rod. It should be noted that the telescopic adjustment of the adjusting vertical pipe 110 in the present application is carried out in an empty state, and its purpose is only to adjust the initial height of the lifting device, and cannot change the lifting stroke, and the lifting stroke still depends on the length of the lifting rack.

[0036] For example, in a workshop, there are two workstations with different heights, and the crane is horizontally moving, when the crane is lifting at the lower height workstation, since the height difference between the lifting vertical pipe 11 and the workstation is large, the adjusting vertical pipe 110 needs to be extended by the electric push rod, so that the upper limit ring 113 of the outer circle of the adjusting vertical pipe 110 is supported on the lower limit ring 114 of the inner circle of the lifting vertical pipe 11, and the weight is supported by the lower limit ring 114 and the upper limit ring 113, thereby reducing the load of the electric push rod, and then the lifting motor drives the lifting gear to realize lifting and lifting.

[0037] When the crane moves to a higher position for hoisting, the adjusting vertical pipe 110 needs to be retracted by the electric push rod due to the small height difference between the lifting vertical pipe 11 and the position, and if the lower connecting plate 17 and the adjusting connecting plate 111 are connected as a whole by the upper bolt, the operation is too complicated. The electric push rod is small in size and cannot bear a large weight, so the support shaft 116 and the socket 118 are arranged in the application. When the electric push rod drives the adjusting vertical pipe 110 to retract in an empty state, the center block 115 rises and pushes the support shaft 116 through the connecting rod 117. Since the end surface of the support shaft 116 is attached to the inner wall of the lifting vertical pipe 11 and cannot extend outward, the adjusting vertical pipe 110 is driven to move upward. When the adjusting connecting plate 111 is attached to the lower connecting plate 17, the adjusting vertical pipe 110 cannot continue to retract upward. At this time, the support shaft 116 is aligned with the socket 118, the electric push rod drives the center block 115 to continue to rise, the support shaft 116 is inserted into the socket 118 through the connecting rod 117, and the weight of the workpiece is borne by the insertion of the support shaft 116 and the socket 118.

[0038] Since the telescopic adjustment of the adjusting vertical pipe 110 is carried out in an empty state, it is limited by the lifting stroke of the lifting rack, so it cannot realize the carrying of the workpiece between the higher position and the lower position, but can only carry the workpiece from the higher position to the higher position or from the lower position to the lower position. The purpose of arranging the adjusting vertical pipe 110 in the application is to adapt to the currently common large-area workshop under the premise of realizing precise carrying. The crane in the large-area workshop needs to carry out carrying operation at different positions, and the heights of the positions are different. Limited by the height of the workshop, the length of the lifting vertical pipe 11 will not be too long, so the lifting stroke is limited and cannot adapt to two different position heights. The application can solve the problem Of course, the above description is not limited to the above examples. The technical features not described in the application can be realized by or using the prior art, which will not be described here. The above examples and drawings are only used to illustrate the technical solutions of the application and are not limited to the application. The application has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the essential scope of the application do not deviate from the purpose of the application, and should also belong to the protection scope of the claims of the application.
