Content of the Utility Model

[0003] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution significantly different from the existing technology. It mainly provides a turnover auxiliary loading device to solve the technical problems proposed in the above background technique.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: a turnover auxiliary loading device, including a vehicle body. A control console is arranged inside the vehicle body. One end of the vehicle body is electrically connected with symmetrically distributed vertical frames. Extension blocks are respectively fixedly connected to the top and bottom of the outer wall of the vertical frame. A first visual sensor and a second visual sensor are respectively arranged on the extension blocks. Both the first visual sensor and the second visual sensor are electrically connected to the vertical frame. A lifting slide bar is electrically connected to the front of the vertical frame. A sliding block is slidably arranged on the lifting slide bar. An insertion plate is fixedly connected to the outer wall of the sliding block.

[0005] A driving box is fixedly connected to the outer wall of the sliding block. A motor is arranged inside the driving box. A sensing wire is arranged inside the vertical frame. Both ends of the sensing wire are electrically connected to the second visual sensor and the motor respectively. A clamping structure is arranged inside the sliding block. The motor is used to drive the clamping structure to clamp so that the sliding block is clamped and fixed on the lifting slide bar.

[0006] Preferably, the clamping structure includes clamping blocks and a threaded rod. The threaded rod is rotatably arranged inside the sliding block, and one end of it is connected to the output end of the motor. The clamping blocks are slidably arranged on the threaded rod and are symmetrically distributed. The opposite surfaces of the two clamping blocks are curved, and their shapes are used to adapt to the outer wall of the lifting slide bar.

[0007] Preferably, driving wheels are rotatably arranged on both outer walls of the vehicle body. Circular array distribution of clamping holes is arranged on the inner wall of the driving wheel. A connecting plate is fixedly connected to the inside of the vehicle body. A locking structure is slidably arranged inside the connecting plate. The locking structure is electrically connected to the first visual sensor and is traction-linked to the control console. The locking structure is used to slidably engage the clamping holes to move and lock the driving wheels.

[0008] Preferably, the locking structure includes a retractable rod and a hydraulic end. One end of the retractable rod is slidably disposed within the connecting plate, the hydraulic end is disposed within the connecting plate, one end of the connecting plate is electrically connected to the first vision sensor, a compression spring is sleeved on the end of the retractable rod located within the connecting plate, and the diameter of the compression spring is greater than the diameter of the outlet of the connecting plate.

[0009] Preferably, a push rod is rotatably disposed on the console. One end of the push rod located within the console is fixedly connected to a turntable, a hook is fixedly connected to the turntable, and a traction wire is wound around the hook.

The first vision sensor is electrically connected to the connecting plate I. When the forklift is loading and unloading goods, when the first vision sensor senses that the forklift is too close to the shelf, it transmits a signal to activate the hydraulic end within the connecting plate. The hydraulic end drives the retractable rod to extend outward, and its end is inserted into the clamping hole on the inner wall of the driving wheel, thereby locking the movement of the forklift and avoiding the situation of colliding with the shelf.

[0012] A push rod is rotatably disposed on the console. By pushing the push rod, the hook on the turntable pulls the traction wire, thereby pulling the extended end of the hydraulic end to contract back to its original position. Subsequently, the locking structure is reset by the resilience of the compression spring and the fixation of the clamping hole is released, thereby releasing the driving wheel.

[0013] The second vision sensor is electrically connected to the driving box on the outer wall of the sliding block. When the forklift lifts the goods, the second vision sensor senses the height of the shelf platform, and then transmits a signal to the driving box through the sensing wire to activate the motor. The motor drives the threaded rod to rotate, thereby causing the clamping block to clamp the lifting slide rod and locking the sliding block at the original lifting position, facilitating the placement of the goods on the plug board.

The front of the vertical frame 3 is electrically connected with a lifting slide rod 4, a sliding block 7 is slidably arranged on the lifting slide rod 4, and a plug board 8 is fixedly connected to the outer wall of the sliding block 7;

[0026] A driving box 9 is fixedly connected to the outer wall of the sliding block 7, a motor 901 is arranged inside the driving box 9, a sensing wire 10 is arranged inside the vertical frame 3, and both ends of the sensing wire 10 are electrically connected to the second visual sensor 6 and the motor 901 respectively. A clamping structure is arranged inside the sliding block 7, and the motor 901 is used to drive the clamping structure to clamp so that the sliding block 7 is clamped and fixed on the lifting slide rod 4.

[0027] Please refer to Figure 2 and Figure 3 , The clamping structure includes clamping blocks 11 and a threaded rod 12. The threaded rod 12 is rotatably arranged inside the sliding block 7, one end of which is connected to the output end of the motor 901. The clamping blocks 11 are slidably arranged on the threaded rod 12 and are symmetrically distributed. The opposite surfaces of the two clamping blocks 11 are curved, and their shapes are used to fit the outer wall of the lifting slide rod 4.

[0028] Please refer to Figure 1 and Figure 5 , Driving wheels 18 are respectively rotatably arranged on the outer walls of both sides of the vehicle body 1. Circular-arrayed clamping holes are formed in the inner walls of the driving wheels 18. A connecting plate 16 is fixedly connected to the inside of the vehicle body 1. A locking structure 17 is slidably arranged inside the connecting plate 16. The locking structure 17 is electrically connected to the first visual sensor 5, and the locking structure 17 is traction-linked to the control console 2. The locking structure 17 is used to slidably engage the clamping holes so that the driving wheels 18 move and lock.

[0029] Please refer to Figure 6 , The locking structure 17 includes a retractable rod 1701 and a hydraulic end 20. One end of the retractable rod 1701 is slidably arranged inside the connecting plate 16. The hydraulic end 20 is arranged inside the connecting plate 16. One end of the connecting plate 16 is electrically connected to the first visual sensor 5. A compression spring 19 is sleeved on the end of the retractable rod 1701 located inside the connecting plate 16, and the diameter of the compression spring 19 is larger than the diameter of the outlet of the connecting plate 16.

[0030] Please refer to Figure 4A push rod 13 is rotatably provided on the console 2, and one end of the push rod 13 located inside the console 2 is fixedly connected to a turntable 14, and a hook is fixedly connected to the turntable 14, and a traction line 15 is wound around the hook, and one end of the traction line 15 is connected to the extended end of the hydraulic end 20. When the first visual sensor 5 stops electrically transmitting a signal, the hydraulic end 20 will cancel the extension, and the hydraulic end 20 itself has sliding properties, so that it can be pulled by the traction line 15 to pull the extended end of the hydraulic end 20 to reset, and then the retraction rod 1701 is pushed back to its original position through the resilience of the compression spring 19 and against the extended end of the hydraulic end 20.

[0031] The specific operation process of the utility model is as follows: when the forklift starts to approach the shelf and prepares to carry out loading and unloading operations, the first visual sensor 5 first detects the proximity distance between the forklift and the shelf through the infrared sensing function. Once the distance reaches the preset safety threshold, the first visual sensor 5 immediately sends a signal to the console 2. After receiving the signal, the console 2 activates the hydraulic end 20 in the connecting plate 16, and the hydraulic end 20 drives the retracting rod 1701 to extend outward. The end of the retracting rod 1701 slides and is inserted into the card hole of the inner wall of the driving wheel 18, so as to realize the movement locking of the forklift and prevent the forklift from continuing to approach the shelf and causing a collision.

[0032] When the forklift starts to lift the goods and prepares to place them at the designated position, the second visual sensor 6 detects the height information of the shelf platform through the infrared sensing function, and the second visual sensor 6 sends a signal to the motor 901 in the drive box 9 through the sensor line 10. After receiving the signal, the motor 901 starts to start and drives the threaded rod 12 to rotate in the sliding block 7. The rotation of the threaded rod 12 drives the clamping block 11 to slide along its surface until the curved surface parts of the two clamping blocks 11 are tightly attached to the outer wall of the lifting slide bar 4, so that the sliding block 7 is locked. At this time, the sliding block 7 and the plug board 8 thereon are fixed at the designated lifting position, and the forklift can safely place the goods on the plug board 8;

[0033] After completing the loading operation, the operator can operate through the push rod 13 on the control console 2, push the push rod 13 to rotate the turntable 14, and the hook on the turntable 14 drives the traction line 15 to move, thereby pulling the extended end of the hydraulic end 20 to retract it. After the extended end of the hydraulic end 20 retracts, the resilience of the compression spring 19 pushes the retracting rod 1701 back to its original position, and disengages from the card hole of the driving wheel 18, unlocking the driving wheel 18. At this time, the vehicle body 1 can be moved to the next working position through the driving wheel 18 again, preparing for the next round of loading operation.

[0034] The above has given an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
