Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a walking jacking hydraulic station with positioning and anti-deviating functions. Background Art

[0002] In bridge construction projects, the accurate jacking position of the beam is the core element to ensure the stability of the overall structure of the bridge and meet the design requirements. The precise jacking position can ensure the precise connection between the beam and the piers, abutments and other basic structures, so that the bridge can reasonably transfer stress when bearing loads, thereby ensuring the safety and durability of the bridge.

[0003] Traditional positioning methods usually rely on fixed reference points on the ground, such as control points and benchmark piles. However, during the bridge construction process, the topography of the construction site may change. Operations such as earth excavation and foundation construction may cause displacement or destruction of reference points.

[0004] During the transportation of bridge beams, especially at open-air construction sites, wind force is a factor that cannot be ignored. The magnitude, direction and point of action of wind force are random and uncertain, and will change with time and space. When the beam is exposed to the wind, the wind will generate multiple forces such as lateral force, lift and torque on the beam, causing the beam to deviate and swing. For example, in strong winds, a large-span beam may be subjected to a large lateral force, causing the beam to deviate from the predetermined transportation path, and may even cause a safety accident. Summary of the invention

[0005] The object of the present invention is to provide a walking push hydraulic station with positioning and anti-deviating function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A walking pushing hydraulic station with a positioning and anti-deviating function, the walking pushing hydraulic station with a positioning and anti-deviating function comprises a mounting frame, a lifting unit and an anti-deviating unit, the mounting frame is placed on a horizontal basis, a slide rail is arranged on the mounting frame, the lifting unit has two groups, the lifting unit is fixedly mounted on the surface of one end of the mounting frame away from the horizontal basis, the lifting unit has the function of accurately positioning the lifting position, the lifting unit is fixedly connected to the anti-deviating unit, the anti-deviating unit is fixedly mounted on the mounting frame, and the anti-deviating unit has the function of correcting the deviation during the transportation of objects.

[0008] The mounting bracket is used to install and fix the lifting unit and the anti-deviation unit. The lifting unit is used for the lifting and precise positioning of articles. The anti-deviation unit is used to correct the deviation caused by the relative displacement during the transportation of articles. When an article needs to be transported, the lifting unit pre-lifts the article and performs precise positioning at the same time, improving the accuracy of transporting the article to the designated position and enhancing work efficiency. The anti-deviation unit corrects the deviation caused by the relative displacement of the article during transportation, thus avoiding the decrease in work efficiency caused by the article falling due to the deviation during the object transportation process.

[0009] Further, the lifting unit includes a hydraulic cylinder, a magnet, a large coil, an electric telescopic rod, an installation box, a straight plate, a lifting plate, a telescopic spring, a conductive block, a pressing plate, a fixed cylinder, a memory spring, a bent rod, a pressure sensor, a small coil, a fixed column and a straight cylinder. The installation box is fixedly installed on the surface of the slide rail far from one end of the horizontal base. The fixed end of the hydraulic cylinder is slidably installed on the inner surface of the installation box. The telescopic end of the hydraulic cylinder is fixedly connected to the straight cylinder. The magnet is fixedly installed on the surface of the telescopic end of the hydraulic cylinder close to one end of the horizontal base. The fixed end of the hydraulic cylinder consists of an inner cylinder and an outer cylinder. The large coil is evenly wound around the outer wall of the inner cylinder of the hydraulic cylinder. The telescopic end of the electric telescopic rod is fixedly connected to the hydraulic cylinder. Both ends of the straight plate are fixedly installed on the outer surfaces of two installation boxes in the same group. There are two lifting plates, and the two lifting plates are connected by a return spring. One end of the telescopic spring is fixedly installed on the inner surface of the straight cylinder close to the horizontal base, and the other end abuts against the conductive block. A circular notch is opened on the conductive block, and a conductive ring is arranged in the notch. The conductive block is slidably installed on the outer surface of the fixed column. The conductive block is electrically connected to the anti-deviation unit. The pressing plate is fixedly installed on the lower surface of the lifting plate far from one end of the horizontal base. The fixed cylinder is fixedly installed on the lower surface of the lifting plate close to one end of the horizontal base parallel to the horizontal axis. The bent rod consists of a horizontal part and a bent part. One end of the memory spring is fixedly installed on the inner surface of the fixed cylinder, and the other end is fixedly connected to the horizontal part of the bent rod. The bent part of the bent rod is fixedly connected to the pressure sensor. The fixed column is fixedly installed inside the straight cylinder. The small coil is evenly wound around the outer surface of the fixed column. One end of the straight cylinder far from the horizontal base abuts against the lifting plate close to one end of the horizontal base. The installation box is fixedly connected to the anti-deviation unit.

[0010] When the object needs to be transported, the controller controls the hydraulic cylinder to lift, thereby driving the lifting plate to move upward to contact the object. As the telescopic part of the hydraulic cylinder drives the magnet upward, the magnetic flux in the large coil changes at this time. When a positive current is generated in the large coil, the controller transmits it to the memory spring. The memory spring is energized and contracts at this time, thereby pulling the bent rod and the pressure sensor to move closer to the center synchronously to clamp the object. When the pressure sensor on one side detects that the pressure value reaches the preset value, the controller maintains the current magnitude at this place and continuously transmits it to the memory spring. The memory spring no longer contracts at this time. If the pressure sensor on the other side exceeds the preset value, it is determined that the pushing position of the lifting plate does not reach the standard. At this time, the controller controls the electric telescopic rod to extend, and pushes the hydraulic cylinder to move until the pressure sensor on this side reaches the preset value, and the electric telescopic rod stops extending. If the pressure sensor on the other side is less than the preset value, it is also determined that the pushing position of the lifting plate does not reach the standard. At this time, the controller controls the electric telescopic rod to contract, and pulls the hydraulic cylinder to move until the pressure sensor on this side reaches the preset value, and the electric telescopic rod stops contracting, so as to accurately position the lifting plate to the best lifting position, thus avoiding the deviation of the lifting position caused by external factors and the reduction of construction efficiency caused by rework.

[0011] Further, the anti-deviation unit includes a slider, a telescopic motor, a support plate, an anti-deviation rod, an anti-deviation plate, an electromagnet 1, an electromagnet 2, a straight rod, a conductive sheet and a vertical cylinder. The slider is fixedly installed on the outer surface of the installation box. The slider is slidably installed on the slide rail. The fixed end of the telescopic motor is fixedly installed on the installation frame. The telescopic end of the telescopic motor is fixedly connected to the slider. The support plate is fixedly installed on the installation frame. The vertical cylinder is fixedly installed on the support plate. The anti-deviation rod is slidably installed in the vertical cylinder. One end of the anti-deviation rod close to the horizontal base is fixedly connected to the electromagnet 2. One end of the anti-deviation rod far from the horizontal base is fixedly connected to the anti-deviation plate. The electromagnet 1 is fixedly installed on the inner surface of the vertical cylinder close to the horizontal base. The electromagnet 1 is electrically connected to the conductive block. The electromagnet 2 is slidably connected to the straight rod. A plurality of conductive sheets are uniformly arranged on the straight rod.

[0012] After positioning is completed, the controller controls the telescopic motor to start, driving the slider to pull the installation box to move synchronously, so that the lifting plate transports the item. During the transportation process, if the item is affected by wind factors and deflects in the left-right direction, or if the item and the lifting plate have relative movement during transportation, resulting in the item deflecting in the front-back direction, due to the change in the center of gravity of the item, on the one hand, the pressing plate descends and contacts the conductive block, while pressing the conductive block to move downward along the fixed column, squeezing the telescopic spring and gradually reducing the effective number of turns of the small coil. The current supplied to the first electromagnet through the small coil gradually increases, and the magnetism of the first electromagnet gradually increases, thereby enhancing the magnetism of the first electromagnet. On the other hand, the lifting plate presses the anti-deviation plate to move downward, driving the anti-deviation rod to push the second electromagnet to move downward in the vertical cylinder along the straight rod and contact the conductive sheet at the same time, causing the second electromagnet to generate magnetism. Under the action of the first electromagnet, the second electromagnet is pushed upward. Under the transmission action of the anti-deviation rod, the anti-deviation plate is driven to push the upward end of the deflected lifting plate to lift and reset, so that the pressing plate is separated from the conductive block, thereby correcting the center of gravity of the deflected object and readjusting it, realizing the anti-deviation of the item, avoiding the problem of the item falling during transportation, affecting the construction efficiency and preventing potential safety hazards.

[0013] Further, the conductive block is composed of a first conductive block at the end far from the telescopic motor and a second conductive block at the end close to the telescopic motor.

[0014] When the item deflects in the front-back direction, when the two first conductive blocks or the two second conductive blocks are pressed and lowered by the corresponding pressing plates, the small coil supplies current to the first electromagnet through the two first conductive blocks or the two second conductive blocks, thereby making the first electromagnet magnetic and pushing the second electromagnet upward, so that the anti-deviation plate corrects the deviation of the item and prevents the item from deflecting. When the item deflects in the left-right direction, when the first conductive block and the second conductive block are pressed and lowered, the small coil supplies current to the first electromagnet through the first conductive block and the second conductive block, thereby making the first electromagnet magnetic and pushing the second electromagnet upward, so that the anti-deviation plate corrects the deviation of the item. In order to avoid problems with one of the currents, the other current can provide partial compensation to maintain a certain magnetism of the first electromagnet, thereby improving the stability and reliability of the system.

[0015] Further, the end of the small coil far from the lifting plate is the current input port.

[0016] When the conductive block is pressed and lowered, as the descending distance reduces the effective number of turns of the small coil, the current increases, so that the magnetism of the first electromagnet gradually increases. The more the item deflects, the stronger the magnetism generated by the first electromagnet, thus ensuring that the reset of the item is not affected.

[0017] Further, in the vertical direction, the currents input by the plurality of conductive sheets from bottom to top gradually decrease.

[0018] When the extrusion plate gradually extrudes the conductive block downward, the effective number of turns of the small coil gradually decreases, and the current supplied to the first electromagnet gradually increases, and the magnetism of the first electromagnet gradually increases. At the same time, the lifting plate extrudes the anti-deviation plate downward, so that while the anti-deviation rod pushes the second electromagnet to gradually move downward, the current passing through the conductive sheet gradually decreases, so that the magnetism of the second electromagnet gradually decreases, buffering the article during deviation and preventing the article from falling due to a large deviation amplitude. During the process of adjusting the deviation reset of the article, the magnetism of the first electromagnet gradually decreases as the effective number of turns of the small coil increases, while the magnetism of the second electromagnet gradually increases as the current of the conductive sheet increases during the rising process. By precisely adjusting the increase and decrease of the magnetism of the first electromagnet and the second electromagnet, precise control of the direction and magnitude of the correction force can be achieved. During the process of correcting the center-of-gravity deviation, according to the weight and the degree of center-of-gravity deviation of the object, the rates and amplitudes of the magnetic changes of the first electromagnet and the second electromagnet are dynamically adjusted, so that the correction force can always effectively act on the object, guiding its center of gravity back to the correct position while avoiding the impact on the object caused by the sudden disappearance or reversal of the correction force, resulting in secondary deviation of the article.

[0019] Further, the first electromagnet and the second electromagnet have the same polarity.

[0020] In order to realize the reset of the offset article, the polarities of the first electromagnet and the second electromagnet are set to be the same.

[0021] Further, the hydraulic cylinder is electrically connected to an external controller, and the conductive sheet is electrically connected to the external controller.

[0022] For the convenience of the timeliness of the device reaction and the automatic operation, the article can be dynamically adjusted automatically and timely during the transportation process, improving the anti-offset performance of the device.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. In the present invention, the magnet in the jacking unit moves upward, changing the magnetic flux in the large coil. When a positive current is generated in the large coil, the memory spring receives the current and contracts, so that the pressure sensor clamps the article. When the pressure sensor detects that the pressure value reaches the preset value, the controller maintains the current magnitude at this place and continuously supplies current to the memory spring. At this time, the memory spring no longer contracts. If the pressure sensor does not reach the preset value, it is determined that the jacking position of the lifting plate does not reach the standard. At this time, the controller controls the telescopic movement of the electric telescopic rod to change the position of the hydraulic cylinder until the pressure sensor reaches the preset value, so as to control the lifting plate to be accurately positioned at the best jacking position, thus avoiding the deviation of the jacking position caused by external factors and reducing the construction efficiency due to re-construction.

[0025] 2. When the object is offset, the present invention squeezes the conductive block along the fixed column downward through the extrusion plate, gradually reducing the effective number of turns of the small coil, changing the current magnitude of the electromagnet 1, and correspondingly changing the magnetism of the electromagnet 1. At the same time, the lifting plate descends to make the electromagnet 2 contact with the conductive sheets of different current magnitudes, changing the magnetism generated by the electromagnet 2. Cooperating with the electromagnet 1, the anti-offset plate pushes the upwardly offset end of the lifting plate to lift and reset, thereby correcting the center of gravity of the offset object and readjusting it, achieving the anti-offset of the object, avoiding the problem of dropping during the transportation of the object, affecting the construction efficiency and preventing potential safety hazards.

[0026] 3. The present invention can achieve precise control of the direction and magnitude of the correction force by precisely adjusting the increase and decrease of the magnetism of the electromagnet 1 and the electromagnet 2. During the process of correcting the center of gravity offset, according to the weight and the degree of center of gravity offset of the object, the rates and amplitudes of the magnetic changes of the electromagnet 1 and the electromagnet 2 are dynamically adjusted, so that the correction force can always effectively act on the object, guiding its center of gravity back to the correct position while avoiding the impact on the object caused by the sudden disappearance or reversal of the correction force, resulting in secondary offset of the object.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment: As Figures 1 - 10 shown, the present invention provides a technical solution:

[0040] As Figure 1 shown, a walking push hydraulic station with a positioning and anti-offset function includes a mounting frame 1, a jacking unit 2 and an anti-offset unit 3. The mounting frame 1 is placed on a horizontal foundation. A slide rail 11 is provided on the mounting frame 1. There are two groups of jacking units 2. The jacking units 2 are fixedly installed on the surface of one end of the mounting frame 1 away from the horizontal foundation. The jacking units 2 have the function of accurately positioning the jacking position. The jacking units 2 are fixedly connected to the anti-offset unit 3. The anti-offset unit 3 is fixedly installed on the mounting frame 1. The anti-offset unit 3 has the function of correcting the offset during the conveying of articles.

[0041] The mounting bracket 1 is used to mount and fix the lifting unit 2 and the anti-deviation unit 3. The lifting unit 2 is used for the lifting and precise positioning of articles. The anti-deviation unit 3 is used to correct the deviation caused by the relative displacement during the conveying process of the articles. When the articles need to be conveyed, after the articles are pre-lifted by the lifting unit 2 and precisely positioned at the same time, the accuracy of conveying the articles to the designated position is improved, and the working efficiency is increased. The anti-deviation unit 3 corrects the deviation caused by the relative displacement of the articles during the transportation process, thereby avoiding the decrease in working efficiency caused by the articles falling due to the deviation during the conveying process of the objects.

[0042] As Figures 1 - 9 shown, the lifting unit 2 includes a hydraulic cylinder 21, a magnet 22, a large coil 23, an electric telescopic rod 24, a mounting box 25, a straight plate 26, a lifting plate 27, a telescopic spring 28, a conductive block 29, a pressing plate 210, a fixed cylinder 211, a memory spring 212, a bent rod 213, a pressure sensor 214, a small coil 215, a fixed column 216 and a straight cylinder 217. The mounting box 25 is fixedly installed on the surface of the far end of the slide rail 11 away from the horizontal base. The fixed end of the hydraulic cylinder 21 is slidably installed on the inner surface of the mounting box 25. The telescopic end of the hydraulic cylinder 21 is fixedly connected to the straight cylinder 217. The magnet 22 is fixedly installed on the surface of the telescopic end of the hydraulic cylinder 21 near the horizontal base. The fixed end of the hydraulic cylinder 21 is composed of an inner cylinder and an outer cylinder. The large coil 23 is evenly wound around the outer wall of the inner cylinder of the hydraulic cylinder 21. The telescopic end of the electric telescopic rod 24 is fixedly connected to the hydraulic cylinder 21. Both ends of the straight plate 26 are fixedly installed on the outer surfaces of two mounting boxes 25 in the same group. There are two lifting plates 27, and the two lifting plates 27 are connected by a return spring. One end of the telescopic spring 28 is fixedly installed on the inner surface of the straight cylinder 217 near the horizontal base, and the other end abuts against the conductive block 29. A circular notch is formed on the conductive block 29, and a conductive ring is arranged in the notch. The conductive block 29 is slidably installed on the outer surface of the fixed column 216. The conductive block 29 is electrically connected to the anti-deviation unit 3. The pressing plate 210 is fixedly installed on the lower surface of the lifting plate 27 at the far end away from the horizontal base. The fixed cylinder 211 is fixedly installed on the lower surface of the lifting plate 27 at the near end parallel to the horizontal axis. The bent rod 213 is composed of a horizontal part and a bent part. One end of the memory spring 212 is fixedly installed on the inner surface of the fixed cylinder 211, and the other end is fixedly connected to the horizontal part of the bent rod 213. The bent part of the bent rod 213 is fixedly connected to the pressure sensor 214. The fixed column 216 is fixedly installed inside the straight cylinder 217. The small coil 215 is evenly wound around the outer surface of the fixed column 216. The far end of the straight cylinder 217 abuts against the lifting plate 27 at the near end and the far end near the horizontal base. The mounting box 25 is fixedly connected to the anti-deviation unit 3.

[0043] When the object needs to be transported, the controller controls the hydraulic cylinder 21 to lift, thereby driving the lifting plate 27 to move upward and contact the object. When the telescopic part of the hydraulic cylinder 21 drives the magnet 22 to move upward, the magnetic flux in the large coil 23 changes. When a positive current is generated in the large coil 23, the controller transmits it to the memory spring 212. At this time, the memory spring 212 is energized and contracts, thereby pulling the bent rod 213 and the pressure sensor 214 to move synchronously towards the center to clamp the object. When the pressure sensor 214 on one side detects that the pressure value reaches the preset value, the controller maintains the current magnitude at this position and continuously transmits it to the memory spring 212. At this time, the memory spring 212 no longer contracts. If the pressure sensor 214 on the other side exceeds the preset value, it is determined that the pushing position of the lifting plate 27 does not meet the standard. At this time, the controller controls the electric telescopic rod 24 to extend, and pushes the hydraulic cylinder 21 to move until the pressure sensor 214 on this side reaches the preset value, and then the electric telescopic rod 24 stops extending. If the pressure sensor 214 on the other side is less than the preset value, it is also determined that the pushing position of the lifting plate 27 does not meet the standard. At this time, the controller controls the electric telescopic rod 24 to contract, and pulls the hydraulic cylinder 21 to move until the pressure sensor 214 on this side reaches the preset value, and then the electric telescopic rod 24 stops contracting, so as to accurately position the lifting plate 27 to the best lifting position, thereby avoiding the deviation of the lifting position caused by external factors and reducing the construction efficiency due to rework.

[0044] As Figure 10 shown, the anti-deviation unit 3 includes a slider 31, a telescopic motor 32, a support plate 33, an anti-deviation rod 34, an anti-deviation plate 35, an electromagnet one 36, an electromagnet two 37, a straight rod 38, a conductive sheet 39 and a vertical cylinder 310. The slider 31 is fixedly installed on the outer surface of the installation box 25, and the slider 31 is slidably installed on the slide rail 11. The fixed end of the telescopic motor 32 is fixedly installed on the installation frame 1, and the telescopic end of the telescopic motor 32 is fixedly connected to the slider 31. The support plate 33 is fixedly installed on the installation frame 1, the vertical cylinder 310 is fixedly installed on the support plate 33, the anti-deviation rod 34 is slidably installed in the vertical cylinder 310, one end of the anti-deviation rod 34 close to the horizontal base is fixedly connected to the electromagnet two 37, and one end of the anti-deviation rod 34 far from the horizontal base is fixedly connected to the anti-deviation plate 35. The electromagnet one 36 is fixedly installed on the inner surface of the vertical cylinder 310 close to the horizontal base, the electromagnet one 36 is electrically connected to the conductive block 29, the electromagnet two 37 is slidably connected to the straight rod 38, and a plurality of conductive sheets 39 are uniformly arranged on the straight rod 38.

[0045] After positioning is completed, the controller controls the telescopic motor 32 to start, thereby driving the slider 31 to pull the installation box 25 to move synchronously, so that the lifting plate 27 transports the article. During the transportation process, if the article is affected by the wind factor and causes the article to shift in the left-right direction, or if the article and the lifting plate 27 have relative movement during the transportation process, resulting in the article shifting in the front-back direction, due to the change of the center of gravity of the article, on the one hand, the pressing plate 210 descends to contact the conductive block 29, and at the same time, the conductive block 29 moves downward along the fixed column 216, squeezing the telescopic spring 28 while the effective number of turns of the small coil 215 gradually decreases, and the current supplied to the first electromagnet 36 through the small coil 215 gradually increases, and the magnetism of the first electromagnet 36 gradually increases, thereby increasing the magnetism of the first electromagnet 36. On the other hand, the lifting plate 27 squeezes the anti-deviation plate 35 to move downward, thereby driving the anti-deviation rod 34 to push the second electromagnet 37 to move downward in the vertical cylinder 310 along the straight rod 38 while contacting the conductive sheet 39, so that the second electromagnet 37 generates magnetism. Under the action of the first electromagnet 36, the second electromagnet 37 is pushed upward. Under the transmission action of the anti-deviation rod 34, the anti-deviation plate 35 is driven to push the upward end of the lifting plate 27 that has shifted downward to be lifted and reset, so that the pressing plate 210 is separated from the conductive block 29, thereby correcting the center of gravity of the offset object and readjusting, realizing the anti-deviation of the article, avoiding the problem of the article falling during the transportation process, affecting the construction efficiency and avoiding potential safety hazards.

[0046] As Figure 9 shown, the conductive block 29 is composed of a first conductive block 291 at the end far from the telescopic motor 32 and a second conductive block 292 at the end close to the telescopic motor 32.

[0047] When the article shifts in the front-back direction, when the two first conductive blocks 291 or the two second conductive blocks 292 are squeezed and lowered by the corresponding pressing plates 210, the small coil 215 supplies current to the first electromagnet 36 through the two first conductive blocks 291 or the two second conductive blocks 292, thereby making the first electromagnet 36 magnetic, pushing the second electromagnet 37 upward, so that the anti-deviation plate 35 corrects the deviation of the article and prevents the article from shifting. When the article shifts in the left-right direction, when the first conductive block 291 and the second conductive block 292 are squeezed and lowered, the small coil 215 supplies current to the first electromagnet 36 through the first conductive block 291 and the second conductive block 292, thereby making the first electromagnet 36 magnetic, pushing the second electromagnet 37 upward, so that the anti-deviation plate 35 corrects the deviation of the article. In order to avoid problems with one of the currents, the other current can provide partial compensation to maintain a certain magnetism of the first electromagnet 36, thereby improving the stability and reliability of the system.

[0048] As Figure 8 shown, the end of the small coil 215 far from the lifting plate 27 is the current input port.

[0049] When the conductive block 29 is squeezed and descends, as the descending distance reduces the effective number of turns of the small coil 215, the current increases, so that the magnetic property of the first electromagnet 36 gradually increases. When the article deflects more, the magnetic property generated by the first electromagnet 36 is stronger, thus ensuring that the reset of the article is not affected.

[0050] As Figure 10 shown, in the vertical direction, the current input by multiple conductive sheets 39 from bottom to top gradually decreases.

[0051] When the pressing plate 210 gradually presses the conductive block 29 to move downward, the effective number of turns of the small coil 215 gradually decreases, while the current supplied to the first electromagnet 36 gradually increases, and the magnetic property of the first electromagnet 36 gradually increases. At the same time, the lifting plate 27 presses the anti-deviation plate 35 to move downward, so that the anti-deviation rod 34 pushes the second electromagnet 37 to gradually move downward. At the same time, the current passing through the conductive sheet 39 gradually decreases, so that the magnetic property of the second electromagnet 37 gradually decreases, buffering the article during deviation to avoid the article falling due to a large deviation amplitude. During the process of adjusting the deviation and reset of the article, the magnetic property of the first electromagnet 36 gradually decreases as the effective number of turns of the small coil 215 increases, while the magnetic property of the second electromagnet 37 gradually increases as the current of the conductive sheet 39 increases during the rising process. By precisely adjusting the increase and decrease of the magnetic properties of the first electromagnet 36 and the second electromagnet 37, precise control of the direction and magnitude of the corrective force can be achieved. During the process of correcting the center-of-gravity deviation, according to the weight and the degree of center-of-gravity deviation of the object, the rates and amplitudes of the magnetic property changes of the first electromagnet 36 and the second electromagnet 37 are dynamically adjusted, so that the corrective force can always effectively act on the object, guiding its center of gravity back to the correct position while avoiding the impact on the object caused by the sudden disappearance or reversal of the corrective force, resulting in secondary deviation of the article.

[0052] As Figure 4 shown, the first electromagnet 36 and the second electromagnet 37 have the same polarity.

[0053] In order to realize the reset of the deflected article, the polarities of the first electromagnet 36 and the second electromagnet 37 are set to be the same.

[0054] As Figure 2 、 Figure 10 shown, the hydraulic cylinder 21 is electrically connected to an external controller, and the conductive sheet 39 is electrically connected to the external controller.

[0055] In order to facilitate the timeliness of the device's response and its automated operation, enabling the article to automatically and timely achieve dynamic adjustment during transportation and improving the anti-deviation performance of the device.

[0056] The working principle of the present invention:

[0057] When the object needs to be transported, the controller controls the hydraulic cylinder 21 to lift, thereby driving the lifting plate 27 to move upward to contact the object. As the telescopic part of the hydraulic cylinder 21 drives the magnet 22 to move upward, the magnetic flux in the large coil 23 changes. When a positive current is generated in the large coil 23, the controller transmits it to the memory spring 212. At this time, the memory spring 212 is energized and contracts, thereby pulling the bent rod 213 and the pressure sensor 214 to move synchronously towards the center to clamp the object. When the pressure sensor 214 on one side detects that the pressure value reaches the preset value, the controller maintains the current magnitude at this point and continuously transmits it to the memory spring 212. At this time, the memory spring 212 no longer contracts. If the pressure sensor 214 on the other side exceeds the preset value, it is determined that the pushing position of the lifting plate 27 does not meet the standard. At this time, the controller controls the electric telescopic rod 24 to extend, and pushes the hydraulic cylinder 21 to move until the pressure sensor 214 on this side reaches the preset value, and then the electric telescopic rod 24 stops extending. If the pressure sensor 214 on the other side is less than the preset value, it is also determined that the pushing position of the lifting plate 27 does not meet the standard. At this time, the controller controls the electric telescopic rod 24 to contract, and pulls the hydraulic cylinder 21 to move until the pressure sensor 214 on this side reaches the preset value, and then the electric telescopic rod 24 stops contracting, so as to accurately position the lifting plate 27 to the optimal lifting position, thereby avoiding the deviation of the lifting position caused by external factors and reducing the construction efficiency due to rework.

[0058] When the object needs to be transported, the controller controls the hydraulic cylinder 21 to lift, thereby driving the lifting plate 27 to move upward and contact the object. As the telescopic part of the hydraulic cylinder 21 drives the magnet 22 upward, the magnetic flux in the large coil 23 changes. When a positive current is generated in the large coil 23, the controller transmits it to the memory spring 212. At this time, the memory spring 212 is energized and contracts, thereby pulling the bent rod 213 and the pressure sensor 214 to move synchronously towards the center to clamp the item. When the pressure sensor 214 on one side detects that the pressure value reaches the preset value, the controller maintains the current magnitude at this position and continuously transmits it to the memory spring 212. At this time, the memory spring 212 no longer contracts. If the pressure sensor 214 on the other side exceeds the preset value, it is determined that the pushing position of the lifting plate 27 does not reach the standard. At this time, the controller controls the electric telescopic rod 24 to extend, and pushes the hydraulic cylinder 21 to move until the pressure sensor 214 on this side reaches the preset value, then the electric telescopic rod 24 stops extending. If the pressure sensor 214 on the other side is less than the preset value, it is also determined that the pushing position of the lifting plate 27 does not reach the standard. At this time, the controller controls the electric telescopic rod 24 to contract, and pulls the hydraulic cylinder 21 to move until the pressure sensor 214 on this side reaches the preset value, then the electric telescopic rod 24 stops contracting, thereby controlling the lifting plate 27 to be accurately positioned at the best lifting position, thus avoiding the deviation of the lifting position caused by external factors, resulting in re - construction and reduced construction efficiency. When the extrusion plate 210 gradually extrudes the conductive block 29 downward, the effective number of turns of the small coil 215 gradually decreases, while the current supplied to the electromagnet one 36 gradually increases, and the magnetism of the electromagnet one 36 gradually increases. At the same time, the lifting plate 27 extrudes the anti - deviation plate 35 downward, so that the anti - deviation rod 34 pushes the electromagnet two 37 to gradually move downward, and at the same time, the current passing through the conductive sheet 39 gradually decreases, making the magnetism of the electromagnet two 37 gradually decrease, buffering the item during deviation and avoiding the item from falling due to a large deviation amplitude. During the process of adjusting the item deviation and resetting, the magnetism of the electromagnet one 36 gradually decreases as the effective number of turns of the small coil 215 increases, while the magnetism of the electromagnet two 37 gradually increases as the current of the conductive sheet 39 increases during the rising process. By precisely adjusting the increase and decrease of the magnetism of the electromagnet one 36 and the electromagnet two 37, the accurate control of the direction and magnitude of the corrective force can be achieved. During the process of correcting the center - of - gravity deviation, according to the weight of the object and the degree of center - of - gravity deviation, the rate and amplitude of the magnetic - property change of the electromagnet one 36 and the electromagnet two 37 are dynamically adjusted, so that the corrective force can always effectively act on the object, guiding its center of gravity back to the correct position while avoiding the impact on the object caused by the sudden disappearance or reversal of the corrective force, resulting in secondary deviation of the item.
