Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, specifically to a gantry crane with a stable moving and multi-directional adjustable lifting mechanism. Background Technology

[0002] Gantry cranes are core lifting equipment in the production palletizing process. They consist of columns, beams, and gripping mechanisms forming a frame structure, resembling a door frame, hence their name. The beams support gripping devices such as vacuum suction cups or mechanical grippers that move horizontally along tracks, working in conjunction with a lifting mechanism to achieve precise positioning in three-dimensional space. They are suitable for the automated stacking of goods such as cartons and boards. During operation, the control system, typically programmed by a PLC, coordinates the actions of each component, completing layered palletizing according to preset parameters, achieving an efficiency of up to one carton per minute. Safety features such as limit devices and rope breakage protection ensure operational stability. Compared to traditional manual palletizing, gantry cranes have the advantages of a smaller footprint, quick assembly and disassembly, and can be fixed to building structures via wall-mounted frames or guy ropes, adapting to diverse needs in factories, warehouses, and other environments.

[0003] Application No. CN120664181A discloses an automatic pipe feeding and packaging mechanism. According to its description and accompanying drawings, the mechanism includes a feeding platform, a gantry frame, an automatic feeding mechanism, and a packaging mechanism. A crossbeam is mounted on the gantry frame, and a vertical frame is mounted on one end of the crossbeam. A second motor drives a first gear to move on a first rack, which in turn drives the cross plate to move, adjusting the position of the gripping part along the Y-axis. A third motor drives a second gear to rotate, which in turn drives a second rack to move, which in turn drives a longitudinal beam to move. The longitudinal beam then drives a fixed frame to move, which in turn drives the gripping block to move along the Z-axis.

[0004] However, the solution has certain limitations: 1. When the horizontal plate on the gantry is moved by the second motor, if it is carrying a heavy object, the horizontal plate may sway slightly during the movement; 2. The entire gantry can only adjust the position of the gripping part along the Y and Z axes, and cannot adjust the X, Y and Z axes, which has certain limitations in production and use. Summary of the Invention

[0005] This invention addresses the aforementioned shortcomings in the design of gantry structures by providing a gantry with a stable and multi-directional adjustable lifting mechanism. This enables the gantry to move smoothly, accurately, stably, and without wobbling in the X, Y, and Z axes when carrying heavy loads, and effectively improves the transmission reliability and durability under harsh working conditions.

[0006] The objective of this invention is achieved through the following technical solution: a gantry frame with a stable moving and multi-directional adjustable lifting part, comprising a stacking support frame, wherein the surface of the stacking support frame is provided with a plurality of stacking crossbeams that can slide back and forth relative to the stacking support frame, the surface of the plurality of stacking crossbeams is provided with stacking bearing members that slide left and right relative to the stacking support frame, and the stacking bearing members are further provided with stacking vertical beams that slide vertically relative to the stacking support frame, wherein the stacking vertical beams pass through the gaps between the plurality of stacking crossbeams during vertical sliding.

[0007] Preferably, the side wall of the palletizing support frame is provided with a plurality of first guide rails, and each end of the palletizing beam is provided with a plurality of first guide rollers. When the palletizing beam moves back and forth relative to the palletizing support frame, each first guide roller always rolls along the first guide rail on the side wall of the palletizing support frame.

[0008] Preferably, the palletizing beams are provided with first roller support plates at both ends. Each first roller support plate includes a horizontal plate parallel to the palletizing support frame and vertical plates vertically arranged on both sides of the horizontal plate. Each vertical plate is rotatably connected with a first guide roller that is locked on a first guide rail. The end of each palletizing beam is connected to the surface of the horizontal plate.

[0009] Preferably, the surface of the palletizing support frame is further provided with a plurality of first rack plates, and a beam support plate is provided between the ends of a plurality of palletizing beams. A first drive motor is provided on the surface of the beam support plate, and the shaft of the first drive motor passes through the beam support plate and is connected to a first drive gear. The first drive gear meshes with the teeth of the first rack plates. A rotatable brush gear is also provided on the side of the horizontal plate near the first rack plates. The brush gear moves simultaneously with the first roller support plate and the brush of the brush gear is in contact with the tooth surface of the first rack plates.

[0010] Preferably, each of the stacking beams is arranged perpendicularly to the first guide rail, and a number of second guide rails are provided on the side wall of the stacking beam. A number of second guide rollers are provided on both sides of each of the stacking support members. When the stacking support member moves left and right along the stacking beam, each second guide roller always rolls along the second guide rail on the side wall of the stacking beam.

[0011] Preferably, the palletizing support is a polygonal plate and has second roller support plates on both sides. Each second roller support plate is rotatably connected to a second guide roller that is locked on a second guide rail. The surface of the palletizing support is also provided with a vertical beam support frame, and the palletizing vertical beam is set inside the vertical beam support frame.

[0012] Preferably, at least one of the palletizing beams has a second rack plate on its surface, and the palletizing support has a second drive motor on its surface. The shaft of the second drive motor passes through the palletizing support and is connected to a second drive gear. The second drive gear meshes with the teeth of the second rack plate. The palletizing support also has a rotatable brush gear on the side near the second rack plate. The brush gear moves simultaneously with the palletizing support and the brush of the brush gear is in contact with the tooth surface of the second rack plate.

[0013] Preferably, the side wall of the stacking vertical beam is also provided with several third guide rails, and the inner wall of the vertical beam support frame is provided with several third guide rollers that are locked on the third guide rails. When the stacking vertical beam moves up and down along the vertical beam support frame, each third guide roller is always locked on the third guide rail on the inner wall of the vertical beam support frame.

[0014] Preferably, a third rack plate is provided on the side wall of the stacking vertical beam, and a third drive motor is provided on the side wall of the vertical beam support frame. The shaft of the third drive motor passes through the vertical beam support frame and is connected to a third drive gear. The third drive gear meshes with the teeth of the third rack plate. A rotatable brush gear is also provided on the side of the vertical beam support frame near the third rack plate. The brush gear moves simultaneously with the stacking support and the brush of the brush gear is in contact with the tooth surface of the third rack plate.

[0015] Preferably, the first guide roller, the second guide roller, and the third guide roller are all V-shaped rollers, and the first guide rail, the second guide rail, and the third guide rail are all V-shaped guide rails. This arrangement is because the V-shaped structure provides excellent guidance and anti-deviation capabilities, effectively preventing derailment or shaking during movement.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. A first drive motor drives a first drive gear, which meshes with a first rack plate fixed on the stacking support frame, thereby moving the entire stacking crossbeam along the Y-axis. A second drive motor drives a second drive gear, which meshes with a second rack plate fixed on the stacking crossbeam, thereby moving the stacking support component along the X-axis. A third drive motor drives a third drive gear, which meshes with a third rack plate fixed on the stacking vertical beam 4, thereby moving the stacking vertical beam up and down within the vertical beam support frame along the Z-axis. Ultimately, the spatial position of the clamp or hook installed at the end of the stacking vertical beam is determined by the three movements mentioned above. By controlling the coordinated operation of the three motors, independent and precise movement along the X, Y, and Z axes is achieved. 2. The first roller support plates at both ends of the stacking beam adopt the cooperation of two rows of first guide rollers and two rows of first guide rails. The second roller support plates on both sides of the stacking load-bearing component adopt a multi-row second guide roller design. The multi-row roller limiting structure increases the contact points and constraint degrees of freedom, significantly enhancing the rigidity of the overall structure, avoiding overturning or swaying under heavy load, realizing the stability and accuracy of movement, and solving the technical problems of easy shaking and low positioning accuracy of existing gantry cranes when handling heavy objects. 3. A brush gear is integrated into the gear-rack transmission system in each direction of movement (X, Y, Z axes). The brush gear moves synchronously with the moving parts and is always in contact with the rack tooth surface, which can remove dust, impurities and other contaminants from the rack in real time. This design integrates the cleaning function directly into the transmission system without additional power or operation, and automatically maintains the cleanliness of the rack tooth surface. It effectively prevents jamming or jamming during gear-rack meshing and improves the reliability and lifespan of the transmission. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 , Figure 2 and Figure 4 As shown, a gantry crane with a stable moving and multi-directional adjustable lifting part includes a stacking support frame 1, which is composed of several metal profiles fixedly connected to each other; the surface of the stacking support frame 1 is provided with several stacking crossbeams 2 that can slide back and forth relative to the stacking support frame 1; in this embodiment, the first guide roller 21, the second guide roller 31 and the third guide roller 36 are all V-shaped rollers, and the first guide rail 11, the second guide rail 27 and the third guide rail 41 are all V-shaped guide rails.

[0020] The side wall of the palletizing support frame 1 is provided with a number of first guide rails 11, and each end of the palletizing beam 2 is provided with a number of first guide rollers 21. When the palletizing beam 2 moves back and forth relative to the palletizing support frame 1, each first guide roller 21 always rolls along the first guide rail 11 on the side wall of the palletizing support frame 1. The two ends of the stacking beam 2 are provided with first roller support plates 20. Each first roller support plate 20 includes a horizontal plate 22 parallel to the stacking support frame 1 and a vertical plate 23 vertically arranged on both sides of the horizontal plate 22. Each vertical plate 23 is rotatably connected to a first guide roller 21 that is locked on a first guide rail 11. The end of each stacking beam 2 is connected to the surface of the horizontal plate 22.

[0021] like Figure 4 and Figure 5 As shown, several first guide rollers 21 are hinged to each vertical plate 23; when the stacking beam 2 slides relative to the surface of the stacking support frame 1, the several first guide rollers 21 always roll along the surface of the first guide rail 11. It should be noted that the first guide rollers 21 on the surface of the vertical plate 23 near the center of the palletizing support frame 1 are arranged in two rows, one above the other. The palletizing support frame 1 is also equipped with two rows of first guide rails 11 based on these two rows of first guide rollers 21. This structural design ensures that the vertical position of the entire first roller support plate 20 is locked by the limit between the two rows of first guide rollers 21 and the first guide rails 11. In particular, when the entire gantry is palletizing and transporting heavy objects, the palletizing beam 2 can only move along the surface of the palletizing support frame 1 under the drive of the first guide rollers 21. This is because the first roller support plate 20 will not produce excessive shaking, which makes it easier for the subsequent palletizing beam 2 to accurately reach the designated position.

[0022] To enable the palletizing beam 2 to slide automatically relative to the surface of the palletizing support frame 1 (the palletizing beam 2 slides relative to the palletizing support frame 1 in the Y-axis direction); the surface of the palletizing support frame 1 is also provided with a plurality of first rack plates 12, and a beam support plate 24 is provided between the ends of the plurality of palletizing beams 2. The surface of the beam support plate 24 is provided with a first drive motor 25, and the shaft of the first drive motor 25 passes through the beam support plate 24 and is connected to a first drive gear 26. The first drive gear 26 meshes with the teeth of the first rack plate 12. The side of the horizontal plate 22 near the first rack plate 12 is also provided with a rotatable brush gear 5. The brush gear 5 moves simultaneously with the first roller support plate 20 and the brush of the brush gear 5 is in contact with the tooth surface of the first rack plate 12. During implementation, the shaft of the first drive motor 25 drives the first drive gear 26 to rotate. During rotation, the first drive gear 26 applies a force to the teeth of the first rack plate 12 through the teeth on its surface. Since the first rack plate 12 is fixedly installed on the palletizing support frame 1, the reaction force generated by the first rack plate 12 is transmitted to the first roller support plate 20 through the first drive gear 26 and the first drive motor 25, so that the entire first roller support plate 20 and the palletizing crossbeam 2 on its surface slide relative to the surface of the palletizing support frame 1.

[0023] It should be noted that, since the brush on the surface of the brush gear 5 is in contact with the tooth surface of the first rack plate 12, and the rotating shaft of the brush gear 5 is also hinged to the bottom of the horizontal plate 22 (the layout principle is as follows). Figure 8 (as shown); therefore, during the sliding guidance process between the first guide roller 21 and the first guide rail 11, the brush gear 5 will rotate and sweep away the impurities and dust on the tooth surface of the first rack plate 12, so that the transmission between the first drive gear 26 and the first rack plate 12 is stable and will not cause jamming or stuck.

[0024] Please refer to the reference. Figure 3 and Figure 6Several stacking beams 2 have stacking support members 3 on their surfaces that can slide left and right relative to the stacking support frame 1. Since the stacking beams 2 are perpendicular to the first guide rail 11 of the stacking support frame 1, the stacking support members 3 can slide left and right relative to the stacking support frame 1, that is, slide along the side wall of the stacking beams 2. To enable the palletizing support 3 to automatically slide along the surface of the palletizing beam 2 (the palletizing support 3 slides relative to the palletizing support frame 1 in the X-axis direction): the palletizing support 3 is a polygonal plate and has second roller support plates 32 on both sides. Each second roller support plate 32 is rotatably connected to a second guide roller 31 that is locked on a second guide rail 27; at least one of the surfaces of the palletizing beam 2 is provided with a second rack plate 28, and the surface of the palletizing support 3 is provided with a second drive motor 34. The shaft of the second drive motor 34 passes through the palletizing support 3 and is connected to a second drive gear 35. The second drive gear 35 meshes with the teeth of the second rack plate 28. The side of the palletizing support 3 near the second rack plate 28 is also provided with a rotatable brush gear 5. The brush gear 5 moves simultaneously with the palletizing support 3 and the brush of the brush gear 5 is in contact with the tooth surface of the second rack plate 28.

[0025] like Figure 6 As shown, during implementation, the shaft of the second drive motor 34 can drive the second drive gear 35 to rotate during rotation; similarly, the second drive gear 35 applies a force to the teeth of the second rack plate 28 through the teeth on its surface during rotation; since the second rack plate 28 is fixedly installed on the stacking beam 2, the reaction force generated by the second rack plate 28 is transmitted to the stacking support 3 through the second drive gear 35 and the second drive motor 34, so that the entire stacking support 3 and its surface vertical beam support frame 33 slide relative to the surface of the stacking beam 2.

[0026] During the sliding process, the second roller support plates 32, which are parallel to the side walls of the stacking beam 2 and the second guide rail 27, are installed on both sides of the stacking support member 3; at the same time, the second guide rollers 31 on each second roller support plate 32 are engaged on the second guide rail 27. This structural design ensures that both sides of the entire palletizing support 3 are locked by the limiting position between the two rows of second guide rollers 31 and the second guide rail 27 on each second roller support plate 32. When the Telon gantry is palletizing and transporting heavy objects, the palletizing support 3 can only move along the surface of the palletizing beam 2 under the drive of the second guide rollers 31. The second roller support plate 32 will not shake, which makes it easy for the subsequent palletizing support 3 to accurately reach the designated position.

[0027] Similarly, since the brush on the surface of the brush gear 5 is attached to the tooth surface of the second rack plate 28, and the rotating shaft of the brush gear 5 is also hinged to the bottom of the stacking support 3, the brush gear 5 will rotate and sweep away the impurities and dust on the tooth surface of the second rack plate 28 during the sliding guidance of the stacking support 3 by the second guide roller 31 and the second guide rail 27, so that the transmission between the second drive gear 35 and the second rack plate 28 is stable and will not cause jamming or jamming.

[0028] Please refer to the reference. Figure 2 , Figure 6 and Figure 7 The surface of the stacking support 3 is also provided with a vertical beam support frame 33, and the stacking vertical beam 4 is disposed inside the vertical beam support frame 33. The stacking support 3 is also provided with a stacking vertical beam 4 that slides vertically relative to the stacking support frame 1, and the stacking vertical beam 4 passes through the gap between the two rows of stacking horizontal beams 2 during the vertical sliding process.

[0029] By using two rows of stacking crossbeams 2 to increase the load-bearing area, the two rows of stacking crossbeams 2 can not only enhance the support force on the stacking load-bearing component 3, but also improve the load-bearing capacity of the stacking vertical beam 4.

[0030] Each of the stacking beams 2 is vertically arranged relative to the first guide rail 11 and a number of second guide rails 27 are provided on the side wall of the stacking beam 2. A number of second guide rollers 31 are provided on both sides of each of the stacking support members 3. When the stacking support member 3 moves left and right along the stacking beam 2, each second guide roller 31 always rolls along the second guide rail 27 on the side wall of the stacking beam 2. The side wall of the stacking vertical beam 4 is also provided with several third guide rails 41, and the inner wall of the vertical beam support frame 33 is provided with several third guide rollers 36 that are rotatably locked on the third guide rails 41. When the stacking vertical beam 4 moves up and down along the vertical beam support frame 33, each third guide roller 36 is always locked on the third guide rail 41 on the inner wall of the vertical beam support frame 33. like Figure 7 As shown, similarly, several third guide rollers 36 are installed on the two opposing inner walls of the vertical beam support frame 33. Therefore, the side walls of the stacking vertical beam 4 are also equipped with several matching third guide rails 41 based on the several third guide rollers 36 on the two inner wall planes of the vertical beam support frame 33. This structural design makes the left and right positions of the entire stacking vertical beam 4 locked by the limit between the third guide rollers 36 and the third guide rails 41. When the gantry crane is stacking and transporting heavy objects, the stacking vertical beam 4 can only move along the inside of the vertical beam support frame 33 under the drive of the third guide rollers 36, which makes it difficult to generate excessive shaking, and facilitates the subsequent stacking vertical beam 4 to accurately reach the designated position.

[0031] The stacking vertical beam 4 is also provided with a third rack plate 42 on its side wall, and a third drive motor 37 is provided on the side wall of the vertical beam support frame 33. The shaft of the third drive motor 37 passes through the vertical beam support frame 33 and is connected to a third drive gear 38. The third drive gear 38 meshes with the teeth of the third rack plate 42. The vertical beam support frame 33 is also provided with a rotatable brush gear 5 on the side near the third rack plate 42. The brush gear 5 moves simultaneously with the stacking support 3 and the brush of the brush gear 5 is in contact with the tooth surface of the third rack plate 42.

[0032] Similarly, during implementation: the shaft of the third drive gear 38 can drive the third drive gear 38 to rotate during rotation; similarly, the third drive gear 38 applies a force to the teeth of the third rack plate 42 through the teeth on its surface during rotation; since the third rack plate 42 is fixedly installed on the stacking vertical beam 4, the force generated by the third drive gear 38 is transmitted to the stacking vertical beam 4, causing the entire stacking vertical beam 4 to move vertically relative to the interior of the vertical beam bearing frame 33.

[0033] like Figure 7 As shown, similarly, since the brush on the surface of the brush gear 5 is attached to the tooth surface of the third rack plate 42, and the rotating shaft of the brush gear 5 is also hinged to the top of the vertical beam support frame 33; therefore, during the sliding guidance of the stacking vertical beam 4 by the third guide roller 36 and the third guide rail 41, the brush gear 5 will rotate and sweep away the impurities and dust on the tooth surface of the third rack plate 42, so that the transmission between the third drive gear 38 and the third rack plate 42 is stable and will not cause jamming or jamming.

[0034] It should be noted that the bottom of the stacking vertical beam 4 is bolted with a clamp or hook assembly. The installation process and the clamp or hook are conventional and common devices used by those skilled in the art, and will not be described in detail here. As mentioned above, the stacking crossbeam 2 can move automatically relative to the stacking support frame 1 about the Y-axis, and the stacking support member 3 on the surface of the stacking crossbeam 2 can move automatically relative to the stacking support frame 1 about the X-axis. Therefore, the automatic up-and-down sliding of the stacking vertical beam 4 on the surface of the stacking support member 3 realizes the movement relative to the stacking support frame 1 about the Z-axis. Therefore, the clamp or hook installed at the bottom of the stacking vertical beam 4 can realize the movement relative to the stacking support frame 1 about the X, Y, and Z axes.

[0035] Working principle and usage of this utility model: To enable the palletizing beam 2 and all its components to move back and forth relative to the palletizing support frame 1: Start the first drive motor 25, which drives the first drive gear 26 to rotate. Since the first rack plate 12 is fixedly installed on the palletizing support frame 1, the reaction force generated by the meshing of the first drive gear 26 and the first rack plate 12 pushes the first roller support plate 20 and the palletizing crossbeam 2 connected thereto to move as a whole.

[0036] During this process, several first guide rollers 21 fixed on the vertical plate 23 of the first roller support plate 20 roll along the first guide rail 11 fixed to the side wall of the stacking support frame 1, providing precise guidance and preventing the stacking beam 2 from swaying under heavy load. The design of the upper and lower rows of first guide rollers 21 further locks the upper and lower positions of the first roller support plate 20, enhancing stability.

[0037] The brush gear 5, which moves with the first roller support plate 20, always has its brushes in contact with the tooth surface of the first rack plate 12, automatically cleaning the tooth surface during movement to ensure smooth transmission.

[0038] To enable the left and right movement of the palletizing support 3 and its components relative to the palletizing crossbeam 2: The second drive motor 34 is started, which drives the second drive gear 35 to rotate. The second drive gear 35 meshes with the second rack plate 28 fixedly installed on the stacking crossbeam 2, and the resulting reaction force pushes the stacking support 3 to move.

[0039] The second guide rollers 31 installed on the second roller support plates 32 on both sides of the stacking support member 3 roll along the second guide rails 27 on the side wall of the stacking beam 2 to ensure that the stacking support member 3 moves smoothly in a straight line and avoids swaying.

[0040] The brush gear 5, which moves with the stacking support 3, automatically cleans the tooth surface of the second rack plate 28 to prevent jamming.

[0041] To achieve vertical lifting and lowering of the palletizing vertical beam 4 relative to the palletizing support member 3: Start the third drive motor 37, which drives the third drive gear 38 to rotate. The third drive gear 38 meshes with the third rack plate 42, which is fixedly installed on the stacking vertical beam 4, and directly drives the stacking vertical beam 4 to perform lifting and lowering movements.

[0042] Several third guide rollers 36 installed on the inner wall of the vertical beam support frame 33 are precisely locked on the third guide rails 41 on the side wall of the stacking vertical beam 4, providing rigid guidance for the lifting and lowering of the stacking vertical beam 4 and effectively preventing it from swaying back and forth and left and right when under load.

[0043] The brush gear 5, which moves with the vertical beam support frame 33, automatically cleans the tooth surface of the third rack plate 42.

[0044] By controlling the coordinated operation of the first drive motor 25, the second drive motor 34 and the third drive motor 37, the clamps or hooks installed at the bottom of the stacking vertical beam 4 can be precisely positioned in three-dimensional space (X, Y, Z axes).

[0045] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
