Description

Technical Field

[0001] This invention relates to the field of transport vehicle technology, specifically to a remote-controlled intelligent flatbed transport vehicle. Background Technology

[0002] Flatbed trucks are common cargo trucks in daily life. These trucks are generally widely used in factories, construction sites and other large-scale production or engineering sites. The strong load-bearing capacity of flatbed trucks has made them play an important role in economic development. According to the warehouse electric flatbed transport vehicle disclosed in authorization announcement number CN 113753143 B, the structure is reasonable and easy to use. The material is lifted by the shovel and clamped by the mounting frame, which provides double support for the material and ensures that it plays a limiting role during transportation, thus ensuring transportation stability. When clamping the material, the mounting frame can also drive the rack and pinion to cooperate with the drive wheel, and then fix the use state of the shovel through the cam, ensuring that the shovel will not adversely affect the material due to the failure of the electric push rod during transportation, thus improving the reliability of use. However, the above-mentioned existing flatbed transport vehicle has a weak carrying capacity, and can only transport one pipe at a time. Moreover, the pipe is easily rolled off during the lifting process, which can easily lead to damage to the pipe. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: The loading mechanism lifts the pipes to the top of the flatbed truck, enabling the flatbed truck to automatically load the goods. The loading mechanism also clamps the pipes, ensuring high stability. When the loading mechanism reverses to pick up goods again, it drives the pushing mechanism to move the pipes one unit position to the right end of the flatbed truck, thus automatically guiding the pipes to the right end of the flatbed truck and preventing them from accumulating at the rear of the flatbed truck. This ensures smooth loading of subsequent goods. The entire process requires no other power mechanism or human intervention, greatly reducing loading costs. Furthermore, an anti-reverse mechanism is provided to ensure that after the inner wall of the clamping recess on the two pushing mechanisms separates from the outer wall of the pipe, the left side of the tension bar slides and releases the anti-reverse pin. The rebound force of the second spring pulls the tension bar to slide to the left to reset, thus preventing the pipe from being pulled to the left again. At the same time, when the tension bar resets to the left, the clamping recess will not contact or interfere with the pipe, ensuring the smooth reset of the pushing mechanism, ready for the next pushing demand.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example: Please refer to Figure 1-8 The remote-controlled intelligent flatbed transport vehicle shown includes a flatbed vehicle 1. A feeding mechanism 2 is movably installed at the rear of the flatbed vehicle 1 for automatic pipe loading. Two front-to-back pushing mechanisms 3 are movably installed on the top of the flatbed vehicle 1 for automatic pushing. Two front-to-back tensioning mechanisms 4 are movably installed on the top of the flatbed vehicle 1 for tensioning and limiting the pipes. Two front-to-back anti-reverse mechanisms 5 are installed on the top of the flatbed vehicle 1 near the rear.

[0019] In this embodiment, reference is made to Figure 2 , Figure 4 , Figure 6 , Figure 7As shown, two front-to-back adapter seats 201 are fixedly connected to the top of the flatbed 1 near the rear. Adapter rods 202 are rotatably connected to the inner walls of both adapter seats 201. Lifting arms 203 are fixedly connected to the inner ends of both adapter rods 202. The two lifting arms 203 extend movably beyond the rear perimeter of the flatbed 1. Hinge columns 204 are hinged to the ends of both lifting arms 203 away from the adapter rods 202. The two hinge columns 204 are connected to a common support for a lifting frame 205. Two front-to-back adapter seats 205 are slidably arranged inside the lifting frame 205. The fabric clamping plate 206 has a support clamping plate 207 fixedly connected to the middle of the outer side of each clamping plate 206. The left and right sides of the lifting frame 205 are fixedly connected to the middle of each hydraulic motor 208. The output shafts of the two hydraulic motors 208 are movably inserted into the interior of the lifting frame 205. Opposing gears 209 are fixedly connected to the output shafts of the two hydraulic motors 208. Opposing gear blocks 2010 mesh with the top and bottom of the opposing gears 209. The two opposing gear blocks 2010 are fixedly connected to the outer walls of the two clamping plates 206 respectively. Specifically, the two hydraulic cylinders 2014 are retracted via remote control. This remote control method is existing technology and will not be described in detail here. The two lifting booms 203 rotate downwards along the hinge positions of the two hinge seats 2013, causing the lifting frame 205 and the two clamping plates 206 to move downwards until the bottom of the two support clamps 207 contact the ground. The two hydraulic cylinders 2014 are then deactivated. The worker has already placed the pipe upright between the two support clamps 207. Then, the worker again uses the remote control to start the two hydraulic motors 208, causing their output shafts to drive the opposing gears 209 to rotate, driving the two opposing gear blocks 2010 towards the center. This further drives the two clamping plates 206 to move synchronously towards the center until the inner walls of the two clamping plates 206 are in close contact with the outer wall of the pipe. The support plates 207 also move towards the center simultaneously to support the outer wall of the pipe. At the same time, the wedges at the bottom of the two support plates 207 are inserted into the bottom of the pipe to lift it. The loading mechanism 2 then limits the pipe in place. Subsequently, the operator uses the remote control to control the two hinge seats 2013, causing the piston rods of the two hinge seats 2013 to extend outward. This lifts the two lifting arms 203 upward along the hinge position of the two hinge seats 2013, lifting the fixed pipe upward. Because the pipe is heavy, it remains vertical as the two lifting arms 203 flip upward, thanks to the hinge between the hinge column 204 and the lifting arms 203. This continues until the two lifting arms 203 flip and move the pipe to the top of the flatbed truck 1, enabling the flatbed transport vehicle to have automatic loading technology.

[0020] In this embodiment, reference is made to Figure 2 , Figure 3 , Figure 4 , Figure 5, Figure 6 As shown, the pushing mechanism 3 includes four sliding seats 301, which are fixedly connected to the top left, right, front, and rear positions of the flatbed trolley 1. Sliding rods 302 are slidably connected to the inner walls of the four sliding seats 301. The two front sliding rods 302 and the two rear sliding rods 302 are all connected to tension plates 304 at their abutting ends. There are two tension plates 304. A first spring 303 is sleeved on the outer wall of each sliding rod 302, and the first spring 303 is fixedly connected to... Between the sliding seat 301 and the tensioning plate 304, a thrust block 305 is fixedly connected to the left side of the outer side of the two tensioning plates 304, and a thrust rod 306 is fixedly connected to the left side of the two thrust blocks 305. It also includes two thrust wheels 307. The two thrust wheels 307 are fixedly connected to the outer wall of the two adapter rods 202 respectively. An arc-shaped notch 3071 is opened on the inner side of the two thrust wheels 307. The outer wall of the two thrust rods 306 abuts against the inner edge of the two thrust wheels 307. The pushing mechanism 3 also includes two tensioning plates 304 distributed front and rear. Tensioning strips 3010 are slidably connected to the inner sides of the two tensioning plates 304. Connecting blocks 3011 are fixedly connected to the top left end of the tensioning strips 3010. Pushing blocks 3012 are fixedly connected to the back side of the two connecting blocks 3011. It also includes two eccentric swing bars 3013. The two eccentric swing bars 3013 are respectively fixedly connected to the outer walls of the two adapter rods 202. The two eccentric swing bars 3013 are located to the left of the two pushing blocks 3012. Multiple clamping recesses 3015 distributed left and right are fixedly connected to the opposite surfaces of the two tensioning strips 3010. Second springs 3016 are fixedly connected to the left side of the two connecting blocks 3011. Limiting pieces 3017 are fixedly connected to the left end of the two second springs 3016. The two limiting pieces 3017 are fixedly connected to the top left end of the flatbed trolley 1. Specifically, when the pipe is moved to the top of the flatbed truck 1, the operator starts two hydraulic motors 208 in reverse via remote control. Following the same principle, the two clamping plates 206 and two supporting clamping plates 207 move and open to the sides, thus placing the pipe at the top end of the flatbed truck 1. Immediately afterwards, the operator remotely activates the piston rods of the two hinge seats 2013 to retract, causing the two lifting arms 203 to flip downwards again. When the two lifting arms 203 flip downwards, they drive the two adapter rods 202 to rotate inside the two adapter seats 201, further driving the thrust wheel 307 and the eccentric swing bar 3013 to rotate. During the rotation of the thrust wheel 307, the thrust rod 306 located inside the arc-shaped notch 3071 is pushed inwards, further pushing the two tensioning plates 304 towards the center under the connecting action of the two thrust blocks 305. The tension bar 3010 is further pushed to move towards the center, so that the two clamping recesses 3015 at the leftmost end clamp the outer wall of the pipe that was previously lifted to the top of the flatbed trolley 1. As the adapter rod 202 continues to rotate, the eccentric swing bar 3013 swings to the right, pushing the push block 3012 to the right, causing the two connecting blocks 3011 to slide to the right inside the two borrowing slots 308, further driving the two tension bars 3010 to move to the right, thereby driving the clamping recesses 3015 and the clamped pipe to move synchronously, moving the pipe to the right end of the flatbed trolley 1 by one unit position, thereby automatically guiding the pipe to the right end of the flatbed trolley 1, avoiding the pipe from accumulating at the rear of the flatbed trolley 1, ensuring the smooth progress of subsequent loading. The whole process does not require the intervention of other power mechanisms and manpower, greatly reducing loading costs.

[0021] In this embodiment, reference is made to Figure 2 , Figure 4 , Figure 8As shown, the tensioning mechanism 4 includes four internal thread seats 401, which are fixedly connected to the top of the flatbed trolley 1. The four internal thread seats 401 are located at the front and rear ends of the two pushing mechanisms 3. Each of the four internal thread seats 401 is threaded with a threaded rod 402. The outer walls of the two threaded rods 402 at the front and the two threaded rods 402 at the rear are rotatably connected to two rectangular plates 403. There are two rectangular plates 403. The tops of the two rectangular plates 403 are fixedly connected to two left and right distributed columns 404. The tops of the two left and right distributed columns 404 are connected to a clamping rod. 405, there are two clamping rods 405. Multiple clamping columns 406 distributed on the left and right are fixedly connected to the outer wall of each clamping rod 405. The multiple clamping columns 406 face the middle of the flatbed 1. The end of each clamping column 406 away from the clamping rod 405 is fixedly connected to a clamping plate 407. The clamping plate 407 is arc-shaped. The inner arc surface of the clamping plate 407 is coated with a soft coating. The tensioning mechanism 4 also includes a limiting sliding hole 408. The limiting sliding hole 408 is opened on the outer side of the tensioning plate 304. Two limiting sliding holes 408 are opened on the outer side of the same tensioning plate 304. The limiting sliding hole 408 is located at the end of the threaded rod 402. Specifically, after all the pipes are mounted on the top of the flatbed trolley 1, the threaded rod 402 is rotated, causing it to screw along the internal thread seat 401 into the pipes until the end of the threaded rod 402 is inserted into the sliding hole 408. This pushes the two tensioning plates 304 and tensioning bars 3010 towards the center until the inside of each clamping recess 3015 abuts against the outer wall of multiple pipes, clamping and limiting the bottom of the pipes. During the screwing of the threaded rod 402, two rectangular plates 403 are pushed towards the center, further driving multiple vertical... The column 404 moves synchronously, pushing the two clamping rods 405 towards the middle. Under the connecting action of the clamping column 406, the clamping plate 407 is fixed until the inner arc surface of the clamping plate 407 just abuts against the outer wall of the pipe, thereby tensioning and fixing the upper part of the pipe to avoid the problem of collision and damage between the pipes during transportation. A soft coating is applied to the inner arc surface of the clamping plate 407 so that the inner arc surface of the clamping plate 407 does not directly contact the outer wall of the pipe, thus providing a buffering effect between the clamping plate 407 and the pipe.

[0022] In this embodiment, reference is made to Figure 2 , Figure 3As shown, the anti-reverse mechanism 5 includes an anti-reverse slide groove 501, which is opened on the top of the flatbed 1. Two anti-reverse slide grooves 501 are located between two pushing mechanisms 3. Anti-reverse sliders 502 are slidably connected inside the two anti-reverse slide grooves 501. Anti-reverse pins 503 are fixedly connected to the top of the two anti-reverse sliders 502. A fourth spring 504 is fixedly connected to one side of the two anti-reverse sliders 502 near the central axis of the flatbed 1. The other end of the fourth spring 504 is fixedly connected to the groove wall of the anti-reverse slide groove 501. Specifically, when the two tension bars 3010 move towards the center, the two clamping recesses 3015 at the leftmost end clamp the outer wall of the pipe that was previously lifted to the top of the flatbed trolley 1. At the same time, the two anti-reverse pins 503 are pushed towards the center, causing the anti-reverse slider 502 to slide along the anti-reverse groove 501 towards the center and compress the fourth spring 504. Thus, by setting the synchronous sliding of the anti-reverse pins 503, the clamping effect of the two tension bars 3010 moving towards the center on the pipe is not interfered with. When the two tension bars 3010 move to the right, they drive the clamping recesses 3015 and the clamped pipe to move synchronously, moving the pipe one unit position to the right end of the flatbed trolley 1. At this time, the left side of the tension bar 3010 is just aligned with the anti-reverse slider. When the outer wall of the nail 503 is flush with the inner wall of the tensioning bar 3010, the inner wall of the anti-reverse nail 503 separates from the outer wall of the anti-reverse nail 503. The rebound force of the fourth spring 504 pushes the anti-reverse slider 502 and the anti-reverse nail 503 to reset, so that the anti-reverse nail 503 abuts against the left end of the tensioning bar 3010, preventing the tensioning bar 3010 from resetting to the right. After the two tensioning plates 304 drive the two tensioning bars 3010 to move and reset to both sides, that is, after the inner wall of the clamping concave block 3015 separates from the outer wall of the pipe, the left side of the tensioning bar 3010 slides and releases the anti-reverse nail 503 from its limit. The rebound force of the second spring 3016 pulls the tensioning bar 3010 to slide and reset to the left, so as not to pull the pipe to the left.

[0023] In this embodiment, reference is made to Figure 6 As shown, telescopic holes 2011 are provided through the front and rear walls of the lifting frame 205. Two telescopic columns 2012 are fixedly connected to the opposite sides of the two clamping plates 206. The outer wall of the telescopic column 2012 is slidably connected to the inner wall of the telescopic hole 2011. Two hinge seats 2013 are fixedly connected to the rear of the flatbed 1. Hydraulic cylinders 2014 are hinged inside the two hinge seats 2013. The two hydraulic cylinders 2014 are located around the two lifting arms 203. The output shafts of the two hydraulic cylinders 2014 are hinged to the outer wall of the two lifting arms 203. Specifically, by setting a sliding connection between the telescopic column 2012 and the telescopic hole 2011, the two clamping plates 206 are movably limited inside the lifting frame 205, and at the same time, they play a guiding role in opening and closing the two clamping plates 206, ensuring the stability of the opening and closing of the two clamping plates 206.

[0024] In this embodiment, reference is made to Figure 3 , Figure 4 As shown, a borrowing groove 308 is provided through the left side of the opposite surface of the two tensioning plates 304. The two borrowing grooves 308 are located around the two connecting blocks 3011. A guide groove 3014 is provided on the back side of the two tensioning bars 3010. A guide block 309 is slidably connected to the inner wall of the two guide grooves 3014. The two guide blocks 309 are located between the two tensioning plates 304. The two guide blocks 309 are fixedly connected to the two tensioning plates 304 respectively. Specifically, by setting the borrowing groove 308, the connecting block 3011 can move freely. By setting the guide block 309 and the guide groove 3014 to slide and guide the tension bar 3010 to slide inside the tension plate 304, the smoothness and stability of the tension bar 3010 sliding are ensured.

[0025] In operation, the remote-controlled intelligent flatbed transport vehicle uses the loading mechanism 2 to move the pipe to the top of the flatbed vehicle 1. First, the operator uses a remote control to retract the piston rods of the two hydraulic cylinders 2014, causing the two lifting arms 203 to rotate downwards along the hinged positions of the two hinge seats 2013. This moves the lifting frame 205 and the two clamping plates 206 downwards until the bottom of the two support clamping plates 207 contacts the ground, at which point the two hydraulic cylinders 2014 are closed. The operator then places the pipe upright between the two support clamping plates 207. Next, the operator uses the remote control again to start the two hydraulic motors 208, causing their output shafts to drive the opposing gears 209 to rotate, which in turn drives the two opposing gear blocks 2010 towards the center, further moving the two clamping plates 206 synchronously towards the center until the two clamping plates 206... The inner wall of 06 is in close contact with the outer wall of the pipe, and its two supporting clamps 207 also move towards the middle at the same time to support the outer wall of the pipe. At the same time, the wedges at the bottom of the two supporting clamps 207 are inserted into the bottom of the pipe to lift the bottom of the pipe. Thus, the pipe is limited by the feeding mechanism 2. Then, the staff uses the remote control to control the two hinge seats 2013 again, so that the piston rods of the two hinge seats 2013 extend outward, thereby lifting the two lifting arms 203 upward along the hinge position of the two hinge seats 2013. At the same time, the fixed pipe is lifted upward. Because the pipe is heavy, when the two lifting arms 203 flip upward, the pipe is always in a vertical state under the hinge of the hinge column 204 and the lifting arm 203 until the two lifting arms 203 flip and move the pipe to the top of the flatbed trolley 1. When the pipe is moved to the top of the flatbed truck 1, the operator uses a remote control to activate two hydraulic motors 208 to move in the opposite direction. Following the same principle, the two clamping plates 206 and two supporting clamping plates 207 move and open to the sides, thus placing the pipe at the top end of the flatbed truck 1. Immediately afterwards, the operator remotely activates the piston rods of the two hinge seats 2013 to retract, causing the two lifting arms 203 to flip downwards again. As the two lifting arms 203 flip downwards, they drive the two adapter rods 202 to rotate inside the two adapter seats 201, further driving the thrust wheel 307 and... As the eccentric swing bar 3013 rotates and the thrust wheel 307 rotates, the thrust rod 306 located inside the arc-shaped notch 3071 is pushed inward. Further, under the combined action of the two thrust blocks 305, the two tension plates 304 are pushed towards the center, further pushing the tension bar 3010 towards the center. This causes the two clamping recesses 3015 at the leftmost end to clamp the outer wall of the pipe previously lifted to the top of the flatbed trolley 1. Simultaneously, the two anti-reverse pins 503 are pushed towards the center, causing the anti-reverse slider 502 to slide along the anti-reverse groove 501 towards the center, compressing the fourth spring. Spring 504, and as the adapter rod 202 continues to rotate, the eccentric swing bar 3013 will swing to the right, pushing the push block 3012 to the right, causing the two connecting blocks 3011 to slide to the right inside the two offset grooves 308, further driving the two tension bars 3010 to move to the right, thereby driving the clamping recess 3015 and the clamped pipe to move synchronously, moving the pipe to the right end of the flatbed trolley 1 by one unit position. At this time, the left side of the tension bar 3010 is just flush with the outer wall of the anti-reverse pin 503, and the inner wall of the tension bar 3010 is flush with the outer wall of the anti-reverse pin 503. When the fourth spring 504 returns to its original position, the anti-reverse slider 502 and anti-reverse pin 503 are pushed back to their original positions, so that the anti-reverse pin 503 abuts against the left end of the tension bar 3010. At the same time, the second spring 3016 is stretched and stored. After the support clamp 207 clamps the next pipe, when the operator remotely starts the piston rod of the two hinge seats 2013 to lift, the two lifting arms 203 and the clamped pipe are lifted to the top of the flatbed 1. The previous pipe is pushed to the right by one unit length, so it will not interfere with the next pipe being placed at the rear of the flatbed 1. When the lifting boom 203 is lifted and rotated upwards, the two transition rods 202 rotate, causing the thrust wheel 307 and the eccentric swing bar 3013 to rotate synchronously. When the eccentric swing bar 3013 rotates, it contacts the rightward thrust of the push block 3012. At this time, the two anti-reverse pins 503 limit the left side of the tension bar 3010, preventing the two tension bars 3010 from resetting to the left. As the thrust wheel 307 continues to return to the thrust rod 306 and slides into the arc-shaped recess 3071, the first spring 30... The rebound force of spring 3 drives tension plate 304 and tension bar 3010 to move to both sides and reset, so that the inner wall of clamping concave block 3015 separates from the outer wall of pipe. At this time, the left side of tension bar 3010 slides and releases the limit of anti-reverse pin 503. The rebound force of second spring 3016 pulls tension bar 3010 to slide to the left and reset. This process is repeated to automatically lift the pipe to the top of flatbed 1 and guide it to the right in sequence, thereby achieving automatic feeding and automatic arrangement, improving the loading convenience of flatbed transport vehicle. After all the pipes are loaded onto the top of the flatbed truck 1, the threaded rod 402 is rotated, causing it to screw along the internal thread seat 401 into the pipe until the end of the threaded rod 402 is inserted into the sliding hole 408. The two tensioning plates 304, together with the tensioning strip 3010, are pushed towards the center until the inside of the clamping recess 3015 abuts against the outer wall of the pipes, clamping and limiting the bottom of the pipes. During the screwing of the threaded rod 402, the two rectangular plates 403 are pushed towards the center, further driving the multiple columns 404 to move synchronously, pushing the two clamping rods 405 towards the center. Under the connection of the clamping columns 406, the clamping support plate 407 is fixed until the inner arc surface of the clamping support plate 407 just abuts against the outer wall of the pipe, thereby tensioning and fixing the upper part of the pipes and preventing the pipes from shifting and colliding and breaking during transportation.
