Description

Technical Field

[0001] This invention relates to the technical field of transportation devices, and in particular to a fully flexible, automatically adaptable device and method for position deviation. Background Technology

[0002] When transporting goods into the carriage, the conveyor system enters the carriage after the vehicle has come to a complete stop. Typically, the length of the conveyor system is similar to the width of the carriage opening, allowing for the stacking of goods up to a pre-set total length. During the stacking process, the conveyor system first stacks goods layer by layer near the front of the carriage, then retracts by the distance of one piece of goods before stacking the next. Once the carriage is fully stacked, the conveyor system gradually detaches from the carriage.

[0003] However, in reality, when the conveying device moves into the carriage, there may be misalignment or skew between the carriage and the conveying device. This can easily lead to the conveying device not being able to move accurately into the carriage. Conveying devices with a width similar to the opening of the carriage may not be able to accurately extend into the carriage, while conveying devices that can easily extend into the carriage may not be able to transport goods of the preset total length in one go. Goods on the same layer may need to be transported multiple times, resulting in low cargo transportation efficiency. Summary of the Invention

[0004] In order to improve the efficiency of cargo stacking, the present invention provides a fully flexible automatic device and method for adapting to positional deviations.

[0005] This invention provides a fully flexible, automatically adaptable device for positional deviations, employing the following technical solution:

[0006] A fully flexible, automatically adaptable device for positional deviation includes a frame, a guide rail on the frame, and a movable work platform mounted on the guide rail. The length of the movable work platform is less than the width of the opening in the carriage.

[0007] The mobile work platform has telescopic sections at opposite ends, which can extend and retract synchronously within the platform. This allows the mobile work platform to slide along the guide rails after it enters the carriage, with one telescopic section abutting against the carriage's inner wall.

[0008] The mobile work platform is equipped with a drive component that drives the telescopic section to extend and retract synchronously.

[0009] In one specific implementation, the drive assembly includes a push rod, a sprocket, and a chain, with one end of the push rod connected to the telescopic section;

[0010] The fixed section is equipped with a drive motor, the sprocket is mounted on the output shaft of the drive motor, the chain is on the sprocket, and the end of the push rod away from the telescopic section is on the chain, so that the push rod pushes the telescopic section to extend and retract synchronously.

[0011] In one specific implementation, the inner wall of the fixed section is provided with rollers, and the side wall of the telescopic section is provided with grooves for the rollers to roll.

[0012] In one specific implementation, the frame is provided with a reset assembly and a braking assembly.

[0013] In one specific implementation, the reset assembly includes a reset spring and a baffle, the reset spring being disposed on the frame and the baffle being disposed in the middle of the reset spring.

[0014] In one specific implementation, the braking assembly includes an electromagnet, a swing arm, and a friction plate. The electromagnet is mounted on the frame, the swing arm is hinged to the frame, one end of the swing arm is provided with a magnetic block, the magnetic block is within the range of action of the electromagnet, and the friction plate is located at the end of the swing arm away from the electromagnet.

[0015] In one specific feasible implementation, the fixed section is equipped with anti-collision wheels.

[0016] This invention also provides a fully flexible, automatic method for adapting to positional deviations, employing the following technical solution:

[0017] A method for fully flexible automatic adaptation to position deviation, used in conjunction with the aforementioned fully flexible automatic adaptation to position deviation device, includes the following steps:

[0018] S1, After the truck comes to a complete stop, the mobile work platform enters the truck bed, and the telescopic section retracts into the fixed section; the mobile work platform is unlocked from the locked state and can slide on the guide rail;

[0019] S2, drive the component to operate, so that the telescopic section extends from the fixed section. The telescopic section on one side first abuts against the inner wall of the carriage, and then pushes the fixed section to move to the other side on the guide rail until the moving work platform meets the preset total length, and stops the extension of the telescopic section.

[0020] S3, stacking goods. After each stack of goods is completed, the mobile work platform detaches from the carriage by the distance of one row of goods.

[0021] S4, when the mobile work platform approaches the door of the carriage, lock the mobile work platform on the guide rail;

[0022] S5, continue stacking the goods until loading is complete and the truck drives away; the drive motor runs to retract the telescopic section into the fixed section;

[0023] S6, unlock the mobile work platform, and the mobile work platform is reset by the reset component.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. After the mobile work platform enters the carriage, the telescopic section extends and abuts against the inner wall of the carriage. It stops after the mobile work platform reaches the preset total length, so that the mobile work platform can transport a whole row of goods, thereby improving the efficiency of goods stacking.

[0026] 2. The braking assembly locks the mobile work platform onto the guide rails, maintaining its stable position when detached from the truck bed and ensuring that goods can be accurately and smoothly stacked inside the truck bed. After the truck leaves, the braking assembly releases the lock on the mobile work platform, which automatically resets under the action of the reset assembly, facilitating continuous loading of trucks.

[0031] The following combination Figures 1-3 The present invention will be described in further detail below.

[0032] Reference Figure 1 and Figure 2 The fully flexible, automatically adaptable positional deviation device includes a frame 1, a guide rail 3 mounted on the frame 1, and a movable working platform mounted on the guide rail 3. The movable working platform has a fixed section 2 and two telescopic sections 4, respectively located at both ends of the fixed section 2 along its length. The two telescopic sections 4 can extend and retract synchronously along the length of the fixed section 2. The telescopic sections 4 extend the working area of ​​the fixed section 2, allowing the movable working platform to extend and retract. After the telescopic sections 4 extend from the fixed section 2, they work together to transport goods.

[0033] The length of the fixed section 2 is less than the width of the opening of the cargo compartment, and the fixed section 2 can extend into the cargo compartment even if the truck is parked in a slightly off-center position.

[0034] After the mobile work platform enters the carriage, the fixed section 2 cannot deliver a single row of goods into the carriage in batches, and its position within the carriage is difficult to control, making it difficult to transport the goods to the accurate location. By having two telescopic sections 4 extend simultaneously into the carriage, the telescopic section 4 closer to the inner wall of the carriage first abuts against the inner wall, pushing the fixed section 2 to slide to the other side on the guide rail 3 until the other telescopic section 4 extends to the preset total length, it is possible to stack a whole row of goods in the carriage while maintaining sufficient movement clearance.

[0035] Reference Figure 1 and Figure 2 The fixed section 2 contains a drive assembly, which includes a push rod 5, a sprocket 8, and a chain 9. A mounting plate 7 is fixed within the fixed section 2, and a drive motor 6 is fixed on the mounting plate 7. There are two sprockets 8: one coaxially fixed to the output shaft of the drive motor 6, and the other fixed to the mounting plate 7. The chain 9 connects the two sprockets 8. One end of the push rod 5 is on the chain 9, and the other end is on the telescopic section 4. The two push rods 5 are located in different directions on the chain 9, meaning they face opposite directions. The operation of the drive motor 6 drives the sprocket 8 to rotate, which in turn drives the push rod 5 forward. Controlling the rotation direction of the sprocket 8 controls the synchronous extension and retraction of the telescopic section 4.

[0036] It is understood that the sprocket 8 and chain 9 in this embodiment are only one way of implementing the drive component. In some other embodiments, the drive component can also be two cylinders or electric actuators facing opposite directions, as long as they can drive the two telescopic sections 4 to extend and retract synchronously.

[0037] Reference Figure 1 and Figure 2 When the mobile work platform enters the carriage, the drive motor 6 runs, causing the push rod 5 to push the telescopic section 4 to extend. Since the two telescopic sections 4 extend synchronously, when one side of the telescopic section 4 first abuts against the inner wall of the carriage, the power of the telescopic section 4 extending further pushes the fixed section 2 to slide on the guide rail 3, causing the fixed section 2 to slide to the other side until the total length of the two telescopic sections 4 after extension meets the preset total length.

[0038] Reference Figure 1 and Figure 2 The inner wall of the fixed section 2 is provided with rollers 11, and the side wall of the telescopic section 4 is provided with a sliding groove 10 for the rollers 11 to roll. While supporting the telescopic section 4, the rollers 11, in cooperation with the sliding groove 10, guide the telescopic direction of the telescopic section 4 during its extension and retraction.

[0039] Reference Figure 1 and Figure 2 The fixed section 2 is equipped with anti-collision wheels 20 at its edge, which protrude from the side wall of the fixed section 2. After each stack of goods is completed, the mobile work platform moves outwards by the distance of one row of goods to stack the next stack of goods. Due to the unevenness of the inner wall of the truck bed, the telescopic section 4, which abuts against the inner wall of the truck bed, may get stuck in the depressions. The anti-collision wheels 20 allow the telescopic section 4 to move along the inner wall of the truck bed, rolling on the inner wall and thus preventing it from getting stuck in the depressions.

[0040] Reference Figure 1 and Figure 3 After the goods are stacked inside the carriage, the mobile work platform needs to be reset for subsequent use. Therefore, a reset assembly is provided inside the frame 1. The reset assembly includes two reset springs 12 and a baffle 13. The two reset springs 12 are arranged in a row and fixed to the side wall of the frame 1. The baffle 13 is fixed in the middle of the two reset springs 12, and the top of the baffle 13 is also fixedly connected to the fixed section 2. In the initial state, the mobile work platform is centered on the frame 1, the baffle 13 is in the middle of the two reset springs 12, and neither of the reset springs 12 is under force. When the fixed section 2 moves under the push of the telescopic section 4, the baffle 13 moves under the drive of the fixed section 2, one reset spring 12 is compressed, and the other reset spring 12 is stretched.

[0041] The mobile work platform continuously pushes against the inner wall of the carriage under the elastic force of the return spring 12. As the mobile work platform gradually detaches from the carriage, the anti-collision wheel 20 will detach from the carriage first. At this time, the mobile work platform will move sideways under the action of the return spring 12, making it difficult to stack the goods at the carriage door. Therefore, the frame 1 is equipped with a brake assembly to lock the mobile work platform on the guide rail 3 to ensure the stacking of goods at the carriage door.

[0042] Reference Figure 1 and Figure 3The braking assembly includes an electromagnet 18, a swing arm 17, and a friction plate 16. The swing arm 17 is hinged to the frame 1, and the electromagnet 18 is fixed to the frame 1. A magnetic block 19 is provided at the bottom end of the swing arm 17, which can be attracted or repelled by the electromagnet 18. The friction plate 16 is located at the end of the swing arm 17 away from the electromagnet 18 and is fixed to the side of the swing arm 17 facing the fixed section 2. Under normal conditions, the magnetic poles of the electromagnet 18 are the same as those of the magnetic block 19, causing the friction plate 16 to press against the side wall of the fixed section 2 and lock the moving work platform on the guide rail 3. After the truck stops, the moving work platform enters the truck bed, and the electromagnet 18 is energized, causing the magnetic poles of the electromagnet 18 to be opposite to those of the magnetic block 19. Under the leverage of the swing arm 17, the friction plate 16 disengages from the side wall of the fixed section 2, allowing the moving work platform to slide freely on the guide rail 3.

[0043] It is easy to understand that the braking assembly is not limited to the form of electromagnet 18 and swing arm 17. In some other embodiments, it can also be a structure such as a hydraulic cylinder, which can apply pushing and pulling forces to the friction plate 16 so that the friction plate 16 abuts against or disengages from the fixed section 2.

[0044] The implementation process of this embodiment is as follows: In the initial state, the telescopic sections 4 are retracted into the fixed section 2, and the magnetic poles of the electromagnet 18 are the same as those of the magnetic block 19. After the driver stops the truck, the mobile work platform extends into the truck bed. Since the width of the fixed section 2 is smaller than the width of the truck bed, and there is no need to ensure that the mobile work platform is centered in the truck bed, the mobile work platform can quickly and accurately enter the truck bed. The electromagnet 18 is energized and attracts the magnetic block 19, allowing the mobile work platform to slide freely on the guide rail 3. The drive motor 6 operates, causing the two telescopic sections 4 to extend synchronously until the total length of the mobile work platform meets the preset total length requirement. Then, the goods are transported. When the mobile work platform approaches the truck bed door, the electromagnet 18 is de-energized and repels the magnetic block 19, locking the fixed section 2 onto the guide rail 3. After the goods are transported and the truck leaves, the telescopic sections 4 retract, the electromagnet 18 is energized and attracts the magnetic block 19, and the mobile work platform is reset by the action of the return spring 12.

[0045] This invention also discloses a method for fully flexible automatic adaptation to positional deviations, used in conjunction with the aforementioned fully flexible automatic adaptation to positional deviations device, comprising the following steps:

[0046] S1, after the truck comes to a complete stop, the mobile work platform enters the truck bed, and the telescopic section 4 retracts into the fixed section 2. The electromagnet 18 is energized, causing the magnetic poles of the magnetic block 19 to change from the same to opposite, so that the friction plate 16 disengages from the fixed section 2, and the mobile work platform can slide freely on the guide rail 3.

[0047] S2, drive motor 6 runs, telescopic section 4 extends synchronously under the action of push rod 5, telescopic section 4 first contacts the inner wall of the carriage and pushes fixed section 2 to slide on guide rail 3 until the total length of the mobile work platform meets the preset total length requirement. The preset total length approaches the width of the carriage, and the extension of telescopic section 4 stops, so that the mobile work platform is basically centered in the carriage.

[0048] S3, stacking goods. After each stack is completed, the mobile work platform moves back one row of goods from the carriage.

[0049] S4, when the mobile work platform approaches the car door, the electromagnet 18 of the braking assembly is de-energized and repels the magnetic block 19, causing the friction plate 16 to lock the mobile work platform onto the guide rail 3. When approaching the car door and stacking the current row of goods, the mobile work platform is inside the car. When stacking the next row of goods, the mobile work platform will move outside the car.

[0050] S5, continue stacking the goods until the entire truckload of goods is stacked, and the truck drives away. Drive motor 6 operates to retract telescopic section 4 into fixed section 2.

[0051] S6, the electromagnet 18 is energized and attracts the magnetic block 19, the friction plate 16 disengages from the moving work platform, and the moving work platform is reset by the action of the return spring 12 and centered on the frame. Afterwards, the electromagnet 18 is de-energized again and repels the magnetic block 19, causing the friction plate 16 to lock the moving work platform on the guide rail 3 for subsequent stacking of other truck cargo.

[0052] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
