Description

Technical Field

[0001] The present invention relates to an intelligent loading platform with adjustable angle, which can effectively adjust the parallelism between the loading platform and the vehicle without affecting the loading of goods, thereby effectively reducing the difficulty of the driver's reverse parking, as well as increasing the vehicle alignment speed and improving the loading efficiency. Background Art

[0002] The loading method of a van can be realized through a loading platform. Goods are transported to the carrier plate of the loading platform manually or by equipment, and then the carrier plate and the goods are synchronously driven into the carriage of the van by the carrier plate driving device installed on the loading platform. Then, under the action of the external material blocking mechanism, the goods can be effectively blocked during the retraction process of the carrier plate, so as to withdraw the carrier plate from the carriage, and then load the goods into the carriage of the van.

[0003] During the vehicle alignment process of the existing loading platform, generally, the driver reverses the vehicle to dock with the loading platform. There are inevitably errors in the operation process, resulting in a certain angle between the front end (the goods output end) of the loading platform and the goods input end of the container of the van. This angle will have obvious adverse effects on the subsequent locking between the loading platform and the van container, as well as the entry and exit of the carrier plate (goods).

[0004] Therefore, the research purpose of the present invention is to design an intelligent loading platform with adjustable angle that can automatically correct the angle with the container of the van, thereby effectively adjusting the parallelism between the loading platform and the vehicle, effectively reducing the difficulty of the driver's reverse parking, as well as increasing the vehicle alignment speed and improving the loading efficiency.

[0010] An angle adjustment mechanism. A corresponding fixing hole runs through the middle of the first support base up and down. The angle adjustment mechanism includes a swing rod swingably installed in the fixing hole and a lifting drive mechanism for adjusting the overall height of the swing rod. The angle of the swing rod is driven by a corresponding swing drive mechanism. The lifting drive mechanism drives the swing rod to descend until its bottom presses tightly against the ground to lift the first support base off the ground. The swing drive mechanism drives the swing rod to swing through a certain angle so that the first support base rotates around the second support base to adjust the relative angle of the platform body.

[0011] A control system for controlling the working processes of the first support oil cylinder, the second support oil cylinder, the carrier plate driving mechanism, the lifting drive mechanism, and the swing drive mechanism.

[0012] A fixing seat is fixedly installed upward on one side of the fixing hole of the first support base. The lifting drive mechanism is a lifting oil cylinder, and the cylinder body of the lifting oil cylinder is rotatably installed on the fixing seat; an adjusting seat is rotatably installed upward on the other side of the fixing hole of the first support base. The adjusting seat is rotatably connected to the piston rod of the lifting oil cylinder on one side where it is not rotatably installed on the first support base; the swing rod is rotatably installed on the adjusting seat. The swing drive mechanism includes a swing drive oil cylinder with its cylinder body rotatably installed on the adjusting seat, and the piston rod of the swing drive oil cylinder is rotatably connected to the upper part of the swing rod.

[0013] A spherical connecting part is integrally formed and arranged downward at the bottom of the swing rod. A corresponding pressing bottom plate is movably connected to the bottom of the spherical connecting part through a corresponding connecting sleeve.

[0014] A group of swing rod mounting plates are arranged upward on one side of the adjusting seat close to its connection end with the first support base. A corresponding reinforcing plate is fixedly connected between the two sides of the swing rod mounting plate, and the swing rod is rotatably installed on the swing rod mounting plate.

[0015] The swing rod is composed of an upper driving section and a lower swing section. The length of the lower swing section is greater than that of the upper driving section, and an installation block with a width greater than that of the upper driving section and the lower swing section is fixedly connected between the upper driving section and the lower swing section. Rotating installation shafts rotatably installed on the swing rod mounting plate are fixedly connected to the two sides of the installation block respectively.

[0016] The bottom of the upper driving section and the top of the lower swinging section are respectively connected to the mounting block by means of threaded connection, and the joints between the upper driving section, the lower swinging section and the mounting block are respectively fixed by welding.

[0017] The cylinder body of the first support oil cylinder is fixed to the first support seat, the piston rod of the first support oil cylinder is fixed to the lower side of the platform body, the first support seat is fixedly connected upward with a first fixed cylinder sleeved around the first support oil cylinder, the first fixed cylinder is movably sleeved upward with a corresponding first guiding cylinder, and one end of the first guiding cylinder not sleeved on the first fixed cylinder is fixed to the lower side of the platform body.

[0018] The cylinder body of the second support oil cylinder is fixed to the second support seat, the piston rod of the second support oil cylinder is fixed to the lower side of the platform body, the middle of the second support seat is fixedly connected upward with a corresponding second fixed cylinder, the second fixed cylinder is movably sleeved upward with a corresponding second guiding cylinder, and one end of the second guiding cylinder not sleeved on the second fixed cylinder is fixed to the lower side of the platform body.

[0019] On both sides of the front end of the platform body, a corresponding group of first distance measuring sensors are arranged forward. The first distance measuring sensors are connected to the control system. When the distance values detected by the group of first distance measuring sensors from both sides of the container differ by more than a first set value ΔL1, the piston rod of the lifting oil cylinder is controlled to extend, driving the adjusting seat to swing downward, so as to drive the pressing base plate at the bottom of the swinging rod to press tightly on the ground, making the first support seat vacated. Then, the piston rod of the swing driving oil cylinder extends or retracts to drive the first support seat to rotate around the second support seat to adjust the relative angle of the platform body until the distance values detected by the group of first distance measuring sensors from both sides of the container differ within a second set range value ΔL2. Then, the piston rod of the lifting oil cylinder is controlled to retract until the first support seat supports the ground, completing the angle adjustment action of the platform body.

[0020] One end of the pressing base plate is vertically and upward fixedly connected with a corresponding distance measuring plate. A second distance measuring sensor adapted to the distance measuring plate is transversely installed on the first support seat. The second distance measuring sensor is connected to the control system. After the angle adjustment is completed, before the piston rod of the lifting oil cylinder retracts, the distance value L1 between the second distance measuring sensor and the distance measuring plate is obtained. During the retraction process of the piston rod of the lifting oil cylinder, the distance value between the second distance measuring sensor and the distance measuring plate is effectively controlled within L1±10mm by extending or retracting the piston rod of the swing driving oil cylinder.

[0021] Advantages of the present invention:

[0022] 1) Based on the existing platform body and carrier board, the present invention is additionally provided with an angle adjustment mechanism, which includes a swinging rod that is swingably installed in the fixing hole of the first support seat, and a lifting drive mechanism for adjusting the overall height of the swinging rod. The angle of the swinging rod is driven by a corresponding swinging drive mechanism. During the angle adjustment process, the swinging rod is driven by the lifting drive mechanism to move downward until its bottom abuts against the ground, so that the first support seat is lifted off the ground; then, the swinging drive mechanism drives the swinging rod to swing through a certain angle, so that the first support seat rotates around the second support seat to adjust the relative angle between the platform body and the carriage. Thus, it can automatically correct the angle with the container of the van-type truck, effectively adjust the parallelism between the platform body and the vehicle, further effectively reduce the difficulty of the driver's reverse parking, and improve the vehicle speed and loading efficiency.

[0023] 2) On one side of the fixing hole of the first support seat of the present invention, a fixing seat is fixedly installed upward, the cylinder body of the lifting oil cylinder is rotatably installed on the fixing seat, and on the other side of the fixing hole of the first support seat, an adjusting seat is rotatably installed upward. The adjusting seat is rotatably connected to the piston rod of the lifting oil cylinder on the side where it is not rotatably installed on the first support seat. In this way, by the telescopic movement of the piston rod of the lifting oil cylinder, the angle of the adjusting seat can be controlled, thereby effectively controlling the overall height of the swinging rod rotatably installed on the adjusting seat; and the swinging drive mechanism includes a swinging drive oil cylinder whose cylinder body is rotatably installed on the adjusting seat. By the telescopic movement of the piston rod of the swinging drive oil cylinder, the first support seat can be driven to rotate around the second support seat to adjust the relative angle between the platform body of the present invention and the truck carriage, thereby effectively ensuring the practical effect of the present invention.

[0024] Most importantly, the fixing seat and the adjusting seat of the present invention are respectively based on the first support seat of the existing loading platform. Through the setting of the fixing hole on the first support seat, the fixing seat and the adjusting seat of the present invention can be effectively arranged on the first support seats on both sides of the fixing hole respectively, so as to integrally install the angle adjustment mechanism of the present invention on the first support seat, and realize the design and installation of the angle adjustment mechanism of the present invention on the premise of compact and simple structure.

[0025] 3) The swinging rod of the present invention is composed of an upper driving section and a lower swinging section. The length of the lower swinging section is greater than that of the upper driving section, and an installation block with a width greater than that of the upper driving section and the lower swinging section is fixedly connected between the upper driving section and the lower swinging section. Rotating installation shafts are fixedly connected to the outside of both sides of the installation block and are rotatably installed on the swinging rod installation plate.

[0026] Since the length of the lower swinging section is greater than that of the upper driving section, under the same swing angle, the arc length trajectory of the upper driving section will be smaller than that of the lower swinging section. Thus, under the smaller stroke of the swinging drive oil cylinder, the angle adjustment with a larger stroke can be completed, so as to improve the adjustment efficiency of the platform body of the present invention.

[0027] Moreover, through the intervention of the mounting block, the bottom of the upper driving section and the top of the lower swinging section are respectively connected to the mounting block by means of threaded connection, and welding and fixing are carried out at the joints between the upper driving section, the lower swinging section and the mounting block. Thus, it can significantly and effectively disperse the force on the mounting block to prevent obvious stress concentration, and further prevent the swinging rod from being excessively deformed or bent during the ground-supporting swing process, thereby effectively improving the practical effect of the present invention.

[0028] 4) The first support base of the present invention is fixedly connected upward with a first fixed cylinder sleeved around the periphery of the first support oil cylinder. The first fixed cylinder is movably sleeved upward with a corresponding first guiding cylinder. One end of the first guiding cylinder that is not sleeved on the first fixed cylinder is fixedly connected to the lower side of the platform body, thus effectively protecting the first support oil cylinder. This is because, after the platform body completes the angle adjustment and the first support base resumes ground support, due to the large weights of components such as the platform body and the carrier plate, the platform body will generate a relatively obvious inertial force under the action of inertia, so it is easy to cause shaking between the platform body and the first support oil cylinder. At this time, by adding the first guiding cylinder and the first fixed cylinder, the connection stability between the platform body and the first leg mechanism can be significantly improved to prevent excessive adverse effects on the installation, driving stability and accuracy of the first support oil cylinder.

[0029] 5) On both sides of the front end of the platform body of the present invention, a corresponding set of first distance sensors are arranged forward. When a set of first distance sensors detect that the difference in the distance values from both sides of the container is greater than the first set value ΔL1, the relative angle of the platform body is adjusted until a set of first distance sensors detect that the difference in the distance values from both sides of the container is within the second set range value ΔL2, and then the piston rod of the lifting oil cylinder is retracted until the first support base supports the ground, thereby completing the angle adjustment action of the platform body. Based on the difference in the distance between both sides of the front end (the shipping end) of the platform body and both sides of the container, the angle between the front end of the platform body and the container can be determined, and by controlling the difference in the distance between both sides of the platform body and the container, the angle between the platform body and the container can be effectively adjusted to a relatively parallel state.

[0030] 6) After the angle adjustment is completed, during the retraction process of the piston rod of the lifting oil cylinder, the adjustment seat will swing upward at a certain angle, which will cause a small displacement of the adjustment rod, resulting in a small change in the angle of the platform body. Since detecting the distance values between the platform body and both sides of the container by a group of first distance measuring sensors requires detecting two distance value data and calculating the difference, using the data detected by a group of first distance measuring sensors to control the compensation amount for the small displacement of the adjustment rod has two problems. Firstly, the compensation accuracy is poor. Secondly, the compensation feedback speed is slow. Therefore, in the present invention, a distance measuring plate is vertically and upwardly fixedly connected to one end of the top pressing bottom plate, and then a second distance measuring sensor adapted to the distance measuring plate is horizontally installed on the first support seat. Before the piston rod of the lifting oil cylinder retracts, the distance value L1 between the second distance measuring sensor and the distance measuring plate is pre-acquired. During the retraction process of the piston rod of the lifting oil cylinder, directly based on the distance value L1, the extension or retraction amount of the piston rod of the swing driving oil cylinder can be controlled more quickly and efficiently, so as to compensate for the small displacement of the adjustment rod caused by the upward swing of the adjustment seat, effectively control the distance value between the second distance measuring sensor and the distance measuring plate within L1 ± 10 mm, and further maintain the angle adjustment accuracy of the platform body.

[0036] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in conjunction with the accompanying drawings in the embodiments:

[0037] Please refer to Figures 1-5 , an intelligent loading platform with adjustable angle, including

[0038] A platform body 1, wherein a first leg mechanism 2 is disposed downwardly on the front side of the platform body 1, wherein the first leg mechanism 2 comprises a group of first supporting oil cylinders 201 installed on the platform body 1, and corresponding first supporting seats 202 are fixedly connected between the bottoms of the first supporting oil cylinders 201; a second leg mechanism 3 is disposed downwardly on the rear side of the platform body 1, wherein the second leg mechanism 3 comprises a group of second supporting oil cylinders 301 installed on the platform body 1, and corresponding second supporting seats 302 are fixedly connected between the bottoms of the second supporting oil cylinders 301;

[0039] The carrier plate 4 is movably arranged on the upper side of the platform body 1. The platform body 1 is fixedly provided with a carrier plate driving mechanism 5 for driving the carrier plate 4 back and forth. The carrier plate driving mechanism 5 in this embodiment includes a driving motor and a reducer connected to the driving motor. The carrier plate is connected to the output shaft end of the reducer by a chain drive.

[0040] Angle adjustment mechanism 6, corresponding fixing holes 7 are set through the middle of the first support seat 202 from top to bottom, the angle adjustment mechanism 6 includes a swing rod 601 that can be swingably installed in the fixing hole 7, and a lifting drive mechanism 602 for adjusting the overall height of the swing rod 601, the angle of the swing rod 601 is driven by a corresponding swing drive mechanism 603, the lifting drive mechanism 602 drives the swing rod 601 to move downward until its bottom is pressed against the ground to make the first support seat 202 empty, the swing drive mechanism 603 drives the swing rod 601 to swing through a certain angle to make the first support seat 202 rotate around the second support seat 302 to adjust the relative angle of the platform body 1.

[0041] The control system is used to control the working progress of the first supporting cylinder 201 , the second supporting cylinder 301 , the carrier driving mechanism 5 , the lifting driving mechanism 602 , and the swing driving mechanism 603 .

[0042] During the angle adjustment process, the lifting drive mechanism 602 drives the swinging rod 601 downward until its bottom is pressed against the ground, so that the first support seat 202 is vacated; thereafter, the swinging drive mechanism 603 drives the swinging rod 601 to swing through a certain angle so that the first support seat 202 rotates around the second support seat 302 to adjust the relative angle of the platform body 1. Thus, the angle can be automatically corrected with the container of the van to effectively adjust the parallelism between the platform body 1 and the vehicle, thereby effectively reducing the difficulty of the driver's reversing, and increasing the speed of the vehicle and the loading efficiency.

[0043] On one side of the fixing hole 7, a fixing seat 8 is fixedly installed upward on the first support seat 202. The lifting drive mechanism 602 is a lifting oil cylinder, and the cylinder body of the lifting oil cylinder is rotatably installed on the fixing seat 8. On the other side of the fixing hole 7 of the first support seat 202, an adjusting seat 9 is rotatably installed upward. One side of the adjusting seat 9 that is not rotatably installed on the first support seat 202 is rotatably connected to the piston rod of the lifting oil cylinder. The swinging rod 601 is rotatably installed on the adjusting seat 9. The swinging drive mechanism 603 includes a swinging drive oil cylinder with its cylinder body rotatably installed on the adjusting seat 9, and the piston rod of the swinging drive oil cylinder is rotatably connected to the upper part of the swinging rod 601.

[0044] At the bottom of the swinging rod 601, a spherical connecting part is integrally formed and arranged downward. A corresponding pressing bottom plate 11 is movably connected to the bottom of the spherical connecting part through a corresponding connecting sleeve 10.

[0045] By the telescopic movement of the piston rod of the lifting oil cylinder, the angle of the adjusting seat 9 can be controlled, so as to effectively control the overall height of the swinging rod 601 rotatably installed on the adjusting seat 9, and effectively control whether the pressing bottom plate 11 at the bottom of the swinging rod 601 supports the ground. The swinging drive mechanism 603 includes a swinging drive oil cylinder with its cylinder body rotatably installed on the adjusting seat 9. By the telescopic movement of the piston rod of the swinging drive oil cylinder, the first support seat 202 can be driven to rotate around the second support seat 302 to adjust the relative angle of the platform body 1 of the present invention, thereby effectively ensuring the practical effect of the present invention.

[0046] Most importantly, the fixing seat 8 and the adjusting seat 9 of the present invention are respectively based on the first support seat 202 of the existing loading platform. Through the setting of the fixing hole 7 on the first support seat 202, the fixing seat 8 and the adjusting seat 9 of the present invention can be effectively arranged on the first support seat 202 on both sides of the fixing hole 7 respectively, so as to integrally install the angle adjusting mechanism 6 of the present invention on the first support seat 202, and realize the design and installation of the angle adjusting mechanism 6 of the present invention on the premise of compact and simple structure.

[0047] On one side of the adjusting seat 9 close to its connection end with the first support seat 202, a group of swinging rod mounting plates 12 are arranged upward. A corresponding reinforcing plate 13 is fixedly connected between both sides of the swinging rod mounting plates 12, and the swinging rod 601 is rotatably installed on the swinging rod mounting plates 12.

[0048] The swing rod 601 is composed of an upper driving section 6011 and a lower swing section 6012. The length of the lower swing section 6012 is greater than that of the upper driving section 6011. An installation block 14 with a width greater than those of the upper driving section 6011 and the lower swing section 6012 is fixedly connected between the upper driving section 6011 and the lower swing section 6012. Rotating mounting shafts 15 that are rotatably mounted to the swing rod mounting plate 12 are fixedly connected to the two sides of the installation block 14 respectively.

[0049] The bottom of the upper driving section 6011 and the top of the lower swing section 6012 are respectively connected to the installation block 14 by threaded connection, and the joints between the upper driving section 6011, the lower swing section 6012 and the installation block 14 are fixedly connected by welding.

[0050] Since the length of the lower swing section 6012 is greater than that of the upper driving section 6011, at the same swing angle, the arc length trajectory of the upper driving section 6011 will be smaller than that of the lower swing section 6012. Thus, angle adjustment with a larger stroke can be completed with a smaller stroke of the swing driving oil cylinder, so as to improve the adjustment efficiency of the platform body 1 of the present invention. And through the intervention of the installation block 14, the bottom of the upper driving section 6011 and the top of the lower swing section 6012 are respectively connected to the installation block 14 by threaded connection, and the joints between the upper driving section 6011, the lower swing section 6012 and the installation block 14 are welded and fixedly connected. Thereby, it can significantly and effectively disperse the force on the installation block 14 to prevent obvious stress concentration, so as to prevent the swing rod 601 from being excessively deformed or bent during the ground-supporting swing process, and further effectively improve the practical effect of the present invention.

[0051] The cylinder body of the first support oil cylinder 201 is fixedly connected to the first support seat 202, the piston rod of the first support oil cylinder 201 is fixedly connected to the lower side of the platform body 1. The first support seat 202 is fixedly connected upward with a first fixed cylinder 16 sleeved on the periphery of the first support oil cylinder 201. A corresponding first guide cylinder 17 is movably sleeved upward on the first fixed cylinder 16. One end of the first guide cylinder 17 that is not sleeved on the first fixed cylinder 16 is fixedly connected to the lower side of the platform body 1.

[0052] After the platform body 1 completes the angle adjustment, when the first support base 202 resumes supporting the ground, due to the large weights of components such as the platform body 1 and the carrier plate 4, the platform body 1 will generate a relatively obvious inertial force under the action of inertia. Therefore, it is easy to cause shaking between the platform body 1 and the first support oil cylinder 201. At this time, by adding the first guide cylinder 17 and the first fixed cylinder 16, the connection stability between the platform body 1 and the first leg mechanism 2 can be significantly improved, so as to prevent excessive adverse effects on the installation, driving stability and accuracy of the first support oil cylinder 201.

[0053] The cylinder body of the second support oil cylinder 301 is fixedly connected to the second support base 302, the piston rod of the second support oil cylinder 301 is fixedly connected to the lower side of the platform body 1, a corresponding second fixed cylinder 18 is fixedly connected upward in the middle of the second support base 302, a corresponding second guide cylinder 19 is movably sleeved upward on the second fixed cylinder 18, and one end of the second guide cylinder 19 not sleeved on the second fixed cylinder 18 is fixedly connected to the lower side of the platform body 1.

[0054] On both sides of the front end of the platform body 1, a corresponding group of first distance sensors are arranged forward. The first distance sensors are connected to the control system. When the distance values detected by the group of first distance sensors from both sides of the container differ by more than the first set value ΔL1, the piston rod of the lifting oil cylinder is controlled to extend, driving the adjusting seat 9 to swing downward, thereby driving the pressing bottom plate 11 at the bottom of the swing rod 601 to press tightly on the ground, making the first support base 202 vacate the ground. Then, the piston rod of the swing driving oil cylinder extends or retracts, driving the first support base 202 to rotate around the second support base 302 to adjust the relative angle of the platform body 1 until the distance values detected by the group of first distance sensors from both sides of the container differ within the second set range value ΔL2, and then the piston rod of the lifting oil cylinder is controlled to retract until the first support base 202 supports the ground, completing the angle adjustment action of the platform body 1.

[0055] Based on the difference in distance between both sides of the front end (shipping end) of the platform body 1 and both sides of the container, the angle size between the platform body 1 and the container can be determined. By controlling the difference in distance between both sides of the platform body 1 and the container, the angle between the platform body 1 and the container can be effectively adjusted to a relatively parallel state.

[0056] One end of the pressing base plate 11 is vertically and upwardly fixedly connected with a corresponding distance measuring plate 20. A second distance measuring sensor 21 adapted to the distance measuring plate 20 is horizontally installed on the first support seat 202. The second distance measuring sensor 21 is connected to the control system. After the angle adjustment is completed, before the piston rod of the lifting oil cylinder retracts, the distance value L1 between the second distance measuring sensor 21 and the distance measuring plate 20 is obtained. During the process of the piston rod of the lifting oil cylinder retracting, the piston rod of the swing driving oil cylinder is effectively extended to control the distance value between the second distance measuring sensor 21 and the distance measuring plate 20 within L1±10mm.

[0057] After the angle adjustment is completed, during the retraction process of the piston rod of the lifting oil cylinder, the adjusting seat 9 will swing upward at a certain angle, which will cause a small displacement of the adjusting rod 601, resulting in a small change in the angle of the platform body 1. Since it is necessary to detect two distance value data for the distance values between the platform body 1 and both sides of the container by a group of first distance measuring sensors and calculate the difference, therefore, controlling the compensation amount for the small displacement of the adjusting rod by the data detected by a group of first distance measuring sensors has two problems. First, the compensation accuracy is poor. Second, the compensation feedback speed is slow. For this reason, the present invention further vertically and upwardly fixedly connects a distance measuring plate 20 at one end of the pressing base plate 11, and then horizontally installs a second distance measuring sensor 21 adapted to the distance measuring plate 20 on the first support seat 202. Before the piston rod of the lifting oil cylinder retracts, the distance value L1 between the second distance measuring sensor 21 and the distance measuring plate 20 is obtained in advance. During the process of the piston rod of the lifting oil cylinder retracting, directly based on the distance value L1, the piston rod of the swing driving oil cylinder can act more quickly and efficiently to compensate for the small displacement of the adjusting rod 601 caused by the swing of the adjusting seat 9, so as to effectively control the distance value between the second distance measuring sensor 21 and the distance measuring plate 20 within L1±mm, and further maintain the angle adjustment accuracy of the platform body.

[0058] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
