Detailed description of the specific embodiment
[0020] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "first", "second", etc. indicate the orientation or position or sequential relationship based on the orientation or position or sequential relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.
[0022] The present utility model provides a bridge-type lifting and stacking device, which includes a longitudinal track 1, a bridge-type lifting support and a controller; the longitudinal track 1 is arranged along a first direction, the bridge-type lifting support is movably arranged on the longitudinal track 1, and the bridge-type lifting support is driven to move by a first driving device 2; the bridge-type lifting support includes a transverse track 3, a gantry track 4, and a lifting and hoisting cross beam 5; the transverse track 3 is arranged along a second direction, the gantry track 4 is movably arranged on the transverse track 3; the gantry track 4 includes two oppositely arranged vertical tracks 401, the vertical tracks 401 are arranged along a third direction, the lifting and hoisting cross beam 5 is arranged to be lifted and lowered between the two vertical tracks 401, and the lifting and hoisting cross beam 5 is driven to perform lifting and lowering movement by a second driving device 6; a forklift mechanism is arranged on the lifting and hoisting cross beam 5, and the forklift mechanism is driven by a third driving device 7 to perform telescopic picking and placing actions; the controller is used to send control commands to the first driving device 2, the second driving device 6 and the third driving device 7.
[0023] The present invention is a bridge-type lifting and stacking device for stacking large and heavy goods. Through the bridge-type lifting structure formed between the gantry rail 4 and the lifting and hoisting cross beam 5, it has the advantages of large weight for picking and placing, and is especially suitable for the application and construction of stacking systems for large and heavy goods. An anti-sway mechanism is provided to further ensure the smooth operation of the overall material picking and placing mechanism, improve the safety of the picking and placing actions of large and heavy goods and the operation of the equipment, reduce the swaying effect during movement, and the lifting and hoisting cross beam 5 installed between the vertical rails 401 can be quickly and accurately positioned to ensure the accuracy of subsequent actions and operations with the equipment system.
[0024] Specifically, as shown in the attached Figure 1 figure. In this embodiment, the lower end of the gantry rail 4 of the bridge-type lifting support is suspended relative to the ground. The suspended structure design of the bridge-type lifting rail structure reduces the layout and construction of the ground rail system. In actual applications, according to the storage needs at different times, the layout position and method of the optimized shelf 8 can be changed. Only by correspondingly adjusting the space coordinate parameters at the software control end of the bridge-type lifting and stacking device, a new adaptation relationship can be formed, which has better flexibility and adaptability and reduces the construction and maintenance costs of the bridge-type lifting system.
[0025] As a feasible implementation manner, as shown in the attached figure, in this embodiment, the second driving device 6 includes a winch 9 arranged at the top of the gantry rail 4 and a pulley assembly 10 arranged on the lifting and hoisting cross beam 5. The winch 9 drives the lifting and hoisting cross beam 5 to move up and down along the third direction through the pulley assembly 10. In this way, through the specific combination of the winch 9 and the pulley assembly 10, a relatively labor-saving driving structure can be formed to ensure the driving force on the lifting and hoisting cross beam 5, improve the maximum load-bearing capacity of the material picking and placing mechanism, and make it more suitable for the picking and placing operation of large and heavy goods described in the present invention.
[0026] Preferably, in this embodiment, a lifting distance measuring mechanism is arranged between the lifting and hoisting cross beam 5 and the gantry rail 4. On the one hand, in actual applications, the winch 9 can be driven by a stepping motor, and the lifting and driving height of the lifting and hoisting cross beam 5 can be controlled by the rotation speed of the stepping motor itself. On the other hand, the actual height position of the lifting and hoisting cross beam 5 can be detected in real time through the arranged lifting distance measuring mechanism to detect and correct the control parameters in real time, ensuring the accuracy of the control of the lifting height position of the lifting and hoisting cross beam 5 and avoiding and reducing operation failures or collision accidents caused by error accumulation.
[0027] Specifically, as shown in the attached drawings, in this embodiment, the lifting and distance measuring mechanism includes a distance measuring sensor 11 provided on the gantry rail 4 and a distance measuring reflector 12 correspondingly provided on the lifting and hoisting cross beam 5. Since the height position of the gantry rail 4 in this embodiment is fixed and it performs synchronous horizontal movement with the lifting and hoisting cross beam 5, the distance measuring sensor can be fixedly installed on the gantry rail 4 as a measurement basis, and the first distance measuring reflector 12 can be fixedly installed on the lifting and hoisting cross beam 5 to follow it synchronously, so as to reflect the measurement signal of the distance measuring sensor, and then the real-time height position of the lifting and hoisting cross beam 5 can be calculated, so that the controller can perform accurate positioning and motion control to ensure the accurate stacking of goods.
[0028] It is easy to understand that since the gantry rail 4 in this embodiment is arranged in a suspended manner, the supporting force point is at its upper contact part with the transverse rail 3, and there is no supporting force point at its lower part. Moreover, the lifting and hoisting cross beam 5 is driven by a winch 9 for lifting. In order to reduce the sway during operation, in this embodiment, an anti-sway mechanism is provided between the lifting and hoisting cross beam 5 and the vertical rail 401. In this way, in the horizontal direction at the left and right ends of the lifting and hoisting cross beam 5, the left and right ends of the lifting and hoisting cross beam 5 are restricted by the gantry rail 4, reducing the sway of the lifting and hoisting cross beam 5 in this direction; in the horizontal direction at the front and rear ends of the lifting and hoisting cross beam 5, the front and rear ends of the lifting and hoisting cross beam 5 are also restricted by the gantry rail 4, reducing the sway of the lifting and hoisting cross beam 5 in this direction, thereby achieving the above-mentioned effect of reducing sway and ensuring the positioning accuracy of the forklift mechanism on the lifting and hoisting cross beam 5 when performing the material picking and placing actions.
[0029] Feasible, as shown in the attached Figure 3 drawings, in this embodiment, the anti-sway mechanism includes a cross beam rail chute 13 opened on the vertical rail 401 and a plurality of limit wheel assemblies provided at the end of the lifting movable beam; the limit wheel assemblies include a first limit wheel 14 and a second limit wheel 15. The first limit wheel 14 abuts against the bottom surface of the cross beam rail chute 13, and the second limit wheel 15 abuts against the two side surfaces of the cross beam rail chute 13.
[0030] On the other hand, in order to reduce the sway of the gantry rail 4 itself, a plurality of strengthening diagonal rods are provided on the upper part of the gantry rail 4. The two ends of the strengthening diagonal rods are respectively connected and fixed to the top cross beam of the gantry rail 4 and the vertical rail 401 to form a triangular stable structure, reducing the sway of the vertical rail 401 during operation.
[0031] As an implementation manner, the object goods in this embodiment are stored in a cuboid cargo frame 16. To ensure the stability of the support for the cargo frame 16, the fork mechanism in this embodiment includes a plurality of telescopic forks 17 that are spaced apart on the lifting and hoisting cross beam 5. The telescopic forks 17 are of an integral structure or a split structure, and the telescopic forks 17 are arranged at equal intervals or unequal intervals, that is, a plurality of spaced support points are formed in the length direction of the cargo frame 16 to form an effective and stable support for it, so as to realize the smooth picking and placing operation of the goods.
[0032] In a preferred implementation manner, as shown in the attached Figure 3 figure, an electrical wiring groove 18 is provided on the outer side of the vertical track 401 relative to the cross beam track chute 13. The power line is arranged in the electrical wiring groove 18 and is electrically connected to the third driving device 7 on the lifting and hoisting cross beam 5, which can well avoid the collision or entanglement of the electrical circuit with obstacles during the operation of the equipment, and better ensure the safety of the operation of the bridge-type lifting and stacking device.
[0033] The above only describes the preferred embodiments of the present invention, but it cannot be understood as a limitation to the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to change. In short, all changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
