Description

Technical Field

[0001] This utility model relates to the field of container flipping and positioning, specifically to a container multi-angle adaptive flipping and positioning device. Background Technology

[0002] In container transportation and loading / unloading operations, tilting and positioning are key processes to ensure logistics efficiency and cargo safety. Traditional tilting devices mostly use fixed robotic arms or hydraulic support structures, and the container tilting is achieved by manually adjusting the clamping position.

[0003] Such devices have the following drawbacks: positioning accuracy depends on the operator's experience, and visual errors can easily cause the container's center of gravity to shift, leading to safety hazards; furthermore, adjusting the tilting angle requires stopping the machine and manually locking it, resulting in poor operational continuity and reduced efficiency. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a container multi-angle adaptive flipping and positioning device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A container multi-angle adaptive tilting and positioning device includes a tilting mounting platform, an automatic positioning clamping component above the tilting mounting platform, and a clamping tilting component on one side of the automatic positioning clamping component.

[0007] To achieve automatic positioning and clamping, the automatic positioning and clamping assembly includes a push rod mounting plate, which is symmetrically mounted above the tilting mounting platform. Clamping electric push rods are symmetrically connected inside the push rod mounting plate, and the output ends of the clamping electric push rods are connected to the clamping mounting plate. A clamping infrared ranging sensor is installed inside the push rod mounting plate. A lifting electric push rod is installed inside the tilting mounting platform, and a container placement plate is connected above the lifting electric push rod. A container placement slot is opened inside the container placement plate, and a lifting infrared ranging sensor is installed inside the container placement plate.

[0008] Furthermore, a controller is installed on one side of the flip-mounted platform.

[0009] Furthermore, the clamping electric actuator, the clamping infrared ranging sensor, and the lifting infrared ranging sensor are electrically connected to the controller.

[0010] Furthermore, in order to achieve the function of clamping and flipping, the clamping and flipping assembly includes a flipping rotating rod, which is symmetrically and movably installed inside the push rod mounting plate. One end of one of the flipping rotating rods is connected to an angle sensor, and a sensor fixing bracket is connected to the periphery of the angle sensor. The sensor fixing bracket is connected to one of the push rod mounting plates, and an adjustment self-locking assembly is connected to one side of the other flipping rotating rod.

[0011] Furthermore, the angle sensor is electrically connected to the controller.

[0012] Furthermore, in order to achieve the self-locking adjustment function, the self-locking adjustment assembly includes an adjusting worm gear, which is connected to a rotating rotating rod. An adjusting worm is engaged on one side of the adjusting worm gear, and a worm fixing plate is movably connected to the periphery of the adjusting worm. The worm fixing plate is fixedly connected to a clamping mounting plate, and a servo motor is connected to one end of the adjusting worm.

[0013] Furthermore, the servo motor is electrically connected to the controller.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model has made improvements to the existing technology. In actual use, the automatic positioning clamping component and the clamping and flipping component solve the problem that the positioning accuracy depends on the operator's experience, and the container's center of gravity may shift due to visual errors, which may cause safety hazards. Furthermore, the flipping angle adjustment requires stopping the machine and manually locking it, resulting in poor work continuity and affecting efficiency.

[0016] (2) In actual use, the worm gear and worm wheel transmission pair of the adjusting worm gear and adjusting worm produce a self-locking effect, which can withstand a maximum torque of 20kN·m without angular deviation. At this time, the clamping electric actuator performs dynamic pressure compensation based on the real-time data of the clamping infrared ranging sensor to ensure clamping stability during the flipping process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of this utility model, a container multi-angle adaptive tilting and positioning device is provided, including a tilting mounting platform 1. The tilting mounting platform 1 is welded from high-strength steel plate, and the top flatness error is controlled within ±0.5mm. An automatic positioning clamping assembly 2 is symmetrically fixed to the reinforcing ribs on both sides of the tilting mounting platform 1 by bolts. Two sets of clamping and tilting assemblies 3 are respectively installed at the left and right ends of the automatic positioning clamping assembly 2. A controller 4 is integrated into the electrical compartment of the tilting mounting platform 1, and a waterproof operation panel is provided on the surface.

[0026] like Figures 1-4As shown, according to an embodiment of the present invention, the container multi-angle adaptive flipping positioning device includes an automatic positioning clamping assembly 2 comprising a push rod mounting plate 201. The push rod mounting plate 201 is made of 20mm thick steel plate with a verticality tolerance of 0.1mm. The clamping electric push rods 202, symmetrically installed internally, are electric push rods with a stroke of 500mm. The surface of the clamping mounting plate 203 is provided with an anti-slip rubber layer, and its connection to the output end of the clamping electric push rod 202 adopts a flange-type mounting structure. The clamping infrared distance sensor 204 is installed in the sensor groove inside the push rod mounting plate 201, with a measurement accuracy of ±0.5mm. The lifting electric push rod 205 adopts a two-stage telescopic structure with a stroke range of 800mm. The container placement plate 206 connected to the top has a container placement groove 207, the inner wall of which is inlaid with a polyurethane buffer pad. The lifting infrared distance sensor 208 is installed on the bottom surface of the container placement plate 206, maintaining a reference measurement distance of 30mm from the top surface of the flipping mounting platform 1.

[0027] Through the above technical solution, after the container enters the container placement slot 207, the lifting infrared ranging sensor 208 detects the height of the container's bottom surface in real time, and the controller 4 drives the lifting electric push rod 205 to perform vertical leveling based on the detected value. At the same time, the two sets of clamping electric push rods 202 extend synchronously under the feedback of the clamping infrared ranging sensor 204, and complete the horizontal clamping and positioning of the container through the container clamping plate 209 connected to one side of the flipping rotating rod 301 inside the clamping mounting plate 203.

[0028] like Figures 1-4 As shown, in the container multi-angle adaptive tilting and positioning device according to an embodiment of this utility model, the tilting rotating rod 301 is machined from 40Cr alloy steel bar with a diameter of 80mm, and its two ends are connected to the push rod mounting plate 201 through tapered roller bearings. The angle sensor 302 is fixed on the machined surface of the right push rod mounting plate 201 through the sensor fixing bracket 303, and adopts an absolute value rotary encoder with a resolution of 0.1°. The clamping and tilting assembly 3 includes the tilting rotating rod 301.

[0029] Through the above technical solution, after receiving the flip angle command from the controller 4, the servo motor 3044 drives the adjusting worm gear 3042 to rotate, which in turn drives the adjusting worm wheel 3041 and the flip rotation rod 301 to rotate by a predetermined angle. The angle sensor 302 feeds back the rotation angle data to the controller 4 in real time, forming a closed-loop control.

[0030] like Figures 1-4As shown, in the container multi-angle adaptive tilting and positioning device according to an embodiment of this utility model, in the self-locking assembly 304, the adjusting worm gear 3041 and the tilting rotating rod 301 are fixed by a key connection, with a module of 4 and a transmission ratio of 30:1. The adjusting worm gear 3042 is a double-headed worm gear, and axial positioning is achieved through the copper sleeve in the worm gear fixing plate 3043. The servo motor 3044 is a 1.5kW AC servo motor equipped with a 1:10 reducer.

[0031] Through the above technical solution, when the set flipping angle is reached, the worm gear transmission pair of adjusting worm wheel 3041 and adjusting worm 3042 generates a self-locking effect, which can withstand a maximum torque of 20kN·m without angular deviation. At this time, the clamping electric actuator 202 performs dynamic pressure compensation based on the real-time data of the clamping infrared ranging sensor 204 to ensure clamping stability during the flipping process.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, when the container enters the container placement slot 207, the lifting infrared ranging sensor 208 detects the height of the container bottom surface in real time, and the controller 4 drives the lifting electric push rod 205 to perform vertical leveling based on the detected value. At the same time, the two sets of clamping electric push rods 202 extend synchronously under the feedback of the clamping infrared ranging sensor 204, and complete the horizontal clamping and positioning of the container through the container clamping plate 209 connected to one side of the flipping rotating rod 301 inside the clamping mounting plate 203.

[0034] Flipping preparation stage: After receiving the flipping angle command from the controller 4, the servo motor 3044 drives the adjusting worm gear 3042 to rotate, which in turn drives the adjusting worm wheel 3041 and the flipping rotating rod 301 to rotate by a predetermined angle. The angle sensor 302 feeds back the rotation angle data to the controller 4 in real time, forming a closed-loop control.

[0035] When the set flipping angle is reached, the worm gear transmission pair of adjusting worm wheel 3041 and adjusting worm 3042 generates a self-locking effect, which can withstand a maximum torque of 20 kN·m without angular deviation. At this time, the clamping electric actuator 202 performs dynamic pressure compensation based on the real-time data of the clamping infrared ranging sensor 204 to ensure clamping stability during the flipping process.

[0036] All electrical components are controlled collaboratively through controller 4. The clamping electric push rod 202, clamping infrared ranging sensor 204, lifting infrared ranging sensor 208, angle sensor 302 and servo motor 3044 are all connected to controller 4 through industrial bus. The control signal transmission cycle is 10ms to ensure that the system response time is less than 0.5 seconds.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
