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 purpose 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: 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.

[0007] The mounting frame is used to install and fix the lifting unit and the anti-deviation unit. The lifting unit is used to lift and accurately position the items, and the anti-deviation unit is used to correct the deviation caused by the relative displacement during the transportation of the items. When the items need to be transported, the lifting unit will pre-lift the items and accurately position them at the same time, thereby improving the accuracy of transporting the items to the designated position and improving work efficiency. The anti-deviation unit will correct the deviation caused by the relative displacement of the items during transportation, thereby avoiding the drop of items caused by the deviation during the transportation process, which will lead to a decrease in work efficiency.

[0008] Furthermore, 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, an extrusion 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 end of the slide rail away from the horizontal foundation, 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 the horizontal foundation, the fixed end of the hydraulic cylinder is composed 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 reset spring. One end of the spring is fixedly mounted on the inner surface of the straight cylinder close to the horizontal foundation, and the other end is abutted 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 mounted on the outer surface of the fixed column, and the conductive block is electrically connected to the anti-bias unit. The extrusion plate is fixedly mounted on the lower surface of the lifting plate at one end away from the horizontal foundation, and the fixed cylinder is fixedly mounted on the lower surface of the lifting plate close to one end of the horizontal foundation 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 mounted 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 mounted inside the straight cylinder, and a small coil is evenly wound on the outer surface of the fixed column. The end of the straight cylinder away from the horizontal foundation is abutted against the lifting plate close to one end of the horizontal foundation, and the mounting box is fixedly connected to the anti-bias unit.

[0009] When an object needs to be transported, the controller controls the hydraulic cylinder to lift, thereby driving the lifting plate to move upward and contact the object. The telescopic part of the hydraulic cylinder drives the magnet to move upward. At this time, the magnetic flux in the large coil changes. 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 bending rod and the pressure sensor synchronously toward the center 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 size at this location and continues to transmit it to the memory spring. At this time, the memory spring no longer contracts. If the pressure sensor on the other side exceeds the preset value, It is determined that the pushing position of the lifting plate has not reached 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 that 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 has not reached the standard. At this time, the controller controls the electric telescopic rod to retract, and pulls the hydraulic cylinder to move until the pressure sensor on that side reaches the preset value, and the electric telescopic rod stops retracting, thereby controlling the lifting plate to be accurately positioned to the optimal lifting position, thereby avoiding deviations in the lifting position due to external factors, resulting in re-construction and reduced construction efficiency.

[0010] Furthermore, the anti-deflection unit includes a slider, a telescopic motor, a support plate, an anti-deflection rod, an anti-deflection plate, an electromagnet 1, an electromagnet 2, a straight rod, a conductive sheet and a vertical tube. The slider is fixedly mounted on the outer surface of the mounting box, the slider is slidably mounted on the slide rail, the fixed end of the telescopic motor is fixedly mounted on the mounting frame, the telescopic end of the telescopic motor is fixedly connected to the slider, the support plate is fixedly mounted on the mounting frame, the vertical tube is fixedly mounted on the support plate, the anti-deflection rod is slidably mounted in the vertical tube, the end of the anti-deflection rod close to the horizontal foundation is fixedly connected to the electromagnet 2, the end of the anti-deflection rod away from the horizontal foundation is fixedly connected to the anti-deflection plate, the electromagnet 1 is fixedly mounted on the inner surface of the end of the vertical tube close to the horizontal foundation, the electromagnet 1 is electrically connected to the conductive block, the electromagnet 2 is slidably connected to the straight rod, and a plurality of conductive sheets are evenly arranged on the straight rod.

[0011] When positioning is completed, the controller controls the telescopic motor to start, thereby driving the slider to pull the installation box to move synchronously, so that the lifting plate can transport items. During transportation, if the items are affected by wind factors and deviate in the left and right directions, or if the items and the lifting plate produce relative movement during transportation, causing the items to deviate in the front and back directions, due to the change in the center of gravity of the items, on the one hand, the squeezing plate descends and contacts the conductive block while squeezing the conductive block to move downward along the fixed column, squeezing the telescopic spring while the effective number of turns of the small coil gradually decreases, and the current transmitted to the electromagnet 1 through the small coil gradually increases, and the magnetic field of the electromagnet 1 The deflection resistance gradually increases, thereby improving the magnetism of electromagnet one. On the other hand, the lifting plate squeezes the anti-deflection plate to move downward, thereby driving the anti-deflection rod to push electromagnet two along the straight rod to move downward in the vertical tube and contact with the conductive sheet, making electromagnet two magnetic. Under the action of electromagnet one, electromagnet two is pushed to move upward. Under the transmission action of the anti-deflection rod, the anti-deflection plate pushes the downward deflected end of the lifting plate to lift and reset upward, so that the extrusion plate is out of contact with the conductive block, thereby correcting the center of gravity of the deflected object and readjusting it, realizing the deviation correction of the objects, avoiding the problem of objects falling during transportation, affecting the construction efficiency and avoiding safety hazards.

[0012] Furthermore, the conductive block is composed of a first conductive block far away from one end of the telescopic motor and a second conductive block close to one end of the telescopic motor.

[0013] When the object deviates in the front-to-back direction, the two first conductive blocks or the two second conductive blocks are squeezed and dropped by the corresponding squeezing plates, and the small coil transmits current to electromagnet one through the two first conductive blocks or the two second conductive blocks, so that electromagnet one is magnetic and pushes electromagnet two to move upward, so that the anti-deflection plate corrects the deviation of the object and prevents the object from deviating. When the object deviates in the left-to-right direction, the first conductive block and the second conductive block are squeezed and dropped, and the small coil transmits current to electromagnet one through the first conductive block and the second conductive block, so that electromagnet one is magnetic and pushes electromagnet two to move upward, so that the anti-deflection plate corrects the deviation of the object. In order to avoid problems with one of the currents, the other current can be partially compensated to maintain a certain magnetism of the electromagnet, thereby improving the stability and reliability of the system.

[0014] Furthermore, one end of the small coil away from the lifting plate is a current input port.

[0015] When the conductive block is squeezed and dropped, the effective number of turns of the small coil decreases as the dropping distance, and the current increases, thereby gradually increasing the magnetism of electromagnet 1. The more the object is deflected, the stronger the magnetism generated by electromagnet 1, thereby ensuring that the resetting of the object is not affected.

[0016] Furthermore, in the vertical direction, the current input to the plurality of conductive sheets decreases step by step from bottom to top.

[0017] When the extrusion plate gradually squeezes the conductive block downward, the effective number of turns of the small coil gradually decreases, and the current delivered to the electromagnet 1 gradually increases, and the magnetism of the electromagnet 1 gradually increases. At the same time, the lifting plate squeezes the anti-deflection plate downward, so that the anti-deflection rod pushes the electromagnet 2 to gradually move downward, and the current passed into the conductive sheet gradually decreases, so that the magnetism of the electromagnet 2 gradually decreases, and the object is buffered when it is offset to avoid the object falling due to a large offset. In the process of adjusting the offset and resetting the object, the magnetism of the electromagnet 1 gradually decreases as the effective number of turns of the small coil increases, and the magnetism of the electromagnet 2 gradually increases as the current of the conductive sheet increases during the rising process. By accurately adjusting the increase and decrease of the magnetism of the electromagnet 1 and the electromagnet 2, the direction and size of the corrective force can be accurately controlled. In the process of correcting the center of gravity offset, according to the weight of the object and the degree of center of gravity offset, the rate and amplitude of the magnetic change of the electromagnet 1 and the electromagnet 2 are dynamically adjusted, so that the corrective force can always effectively act on the object, guide its center of gravity back to the correct position, and avoid the impact on the object caused by the sudden disappearance or reversal of the corrective force, causing the secondary offset of the object.

[0018] Furthermore, the polarity of the electromagnet 1 and the electromagnet 2 is the same.

[0019] In order to reset the offset object, the polarity of electromagnet 1 and electromagnet 2 is set to be the same.

[0020] Furthermore, the hydraulic cylinder is electrically connected to an external controller, and the conductive sheet is electrically connected to the external controller.

[0021] In order to facilitate the timely response and automation of the device, the items can be automatically and timely dynamically adjusted during transportation, thereby improving the anti-drift performance of the device.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention changes the magnetic flux in the large coil by moving the magnet in the lifting unit upward. When a positive current is generated in the large coil, the memory spring receives the current and contracts, causing the pressure sensor to clamp the object. When the pressure sensor detects that the pressure value reaches a preset value, the controller maintains the current size there and continuously transmits it 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 lifting position of the lifting plate does not meet the standard. At this time, the controller controls the electric telescopic rod to extend and retract, and changes the position of the hydraulic cylinder until the pressure sensor reaches the preset value, thereby controlling the lifting plate to be accurately positioned to the optimal lifting position, thereby avoiding deviations in the lifting position due to external factors, resulting in re-construction and reduced construction efficiency.

[0023] 2. When the object is offset, the present invention squeezes the conductive block through the extrusion plate to move it downward along the fixed column, gradually reducing the effective number of turns of the small coil, changing the current of electromagnet one, and changing the magnetism of electromagnet one accordingly. At the same time, the lifting plate descends to make electromagnet two contact with conductive sheets of different currents, changing the magnetism of electromagnet two, and cooperating with electromagnet one to make the anti-deviation plate push the end of the lifting plate that is offset downward to lift it upward and reset it, thereby correcting the center of gravity of the offset object and readjusting it, realizing object correction, avoiding the problem of objects falling during transportation, affecting construction efficiency and avoiding safety hazards.

[0024] 3. The present invention can achieve precise control of the direction and size of the corrective force by accurately adjusting the increase or decrease of the magnetism of electromagnet 1 and electromagnet 2. In the process of correcting the center of gravity shift, the rate and amplitude of the magnetic change of electromagnet 1 and electromagnet 2 are dynamically adjusted according to the weight of the object and the degree of center of gravity shift, 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, causing secondary shift of the object.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example: Figure 1-Figure 10 As shown, the present invention provides a technical solution: like Figure 1 As shown, a walking jacking hydraulic station with positioning and anti-deviation functions includes a mounting frame 1, a lifting unit 2 and an anti-deviation unit 3. The mounting frame 1 is placed on a horizontal basis, and a slide rail 11 is arranged on the mounting frame 1. The lifting unit 2 has two groups, and the lifting unit 2 is fixedly mounted on the surface of one end of the mounting frame 1 away from the horizontal basis. The lifting unit 2 has the function of accurately positioning the lifting position, and the lifting unit 2 is fixedly connected to the anti-deviation unit 3, and the anti-deviation unit 3 is fixedly mounted on the mounting frame 1. The anti-deviation unit 3 has the function of correcting the deviation during the transportation of objects.

[0029] The mounting frame 1 is used to install and fix the lifting unit 2 and the anti-deviation unit 3. The lifting unit 2 is used to lift and accurately position the items. The anti-deviation unit 3 is used to correct the deviation caused by the relative displacement generated during the transportation of the items. When the items need to be transported, the lifting unit 2 pre-lifts the items and accurately positions them at the same time, thereby improving the accuracy of transporting the items to the specified position and improving work efficiency. The anti-deviation unit 3 corrects the deviation caused by the relative displacement of the items during transportation, thereby avoiding the drop of the items caused by the deviation during the transportation process, which reduces the work efficiency.

[0030] like Figure 1-Figure 9As 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, an extrusion 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 mounted on the surface of one end of the slide rail 11 away from the horizontal foundation, the fixed end of the hydraulic cylinder 21 is slidably mounted 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, and the magnet 22 is fixedly mounted on the telescopic end of the hydraulic cylinder 21 close to the horizontal foundation On one end surface, 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 on 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, and both ends of the straight plate 26 are fixedly installed on the outer surfaces of the two mounting boxes 25 in the same group. There are two lifting plates 27, and the two lifting plates 27 are connected by a reset spring. One end of the telescopic spring 28 is fixedly installed on the inner surface of the straight cylinder 217 close to the horizontal foundation, and the other end is in contact with the conductive block 29. A circular notch is provided on the conductive block 29, and a conductive ring is provided in the notch. The conductive block 29 is slidably installed on the outer surface of the fixed column 216, and the conductive block 29 is electrically connected to the anti-bias unit 3. The extrusion plate 210 is fixedly installed on the lower surface of the lifting plate 27 at one end away from the horizontal foundation, the fixed cylinder 211 is fixedly installed on the lower surface of the lifting plate 27 close to the horizontal foundation parallel to the horizontal axis, the bent rod 213 consists 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, and the outer surface of the fixed column 216 is evenly wound with a small coil 215, the straight cylinder 217 is away from the horizontal foundation at one end and abuts against the lifting plate 27 close to the horizontal foundation, and the mounting box 25 is fixedly connected to the anti-bias unit 3.

[0031] When an 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. The telescopic part of the hydraulic cylinder 21 drives the magnet 22 to move upward. At this time, 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. The memory spring 212 is energized and contracts at this time, thereby pulling the bending rod 213 and the pressure sensor 214 to move synchronously toward 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 size at this location and continues to transmit 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 When the preset value is reached, it is determined that the pushing position of the lifting plate 27 has not reached the standard. At this time, the controller controls the electric telescopic rod 24 to extend, and pushes the hydraulic cylinder 21 to move to the pressure sensor 214 on that side to reach the preset value, and 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 has not reached the standard. At this time, the controller controls the electric telescopic rod 24 to retract, and pulls the hydraulic cylinder 21 to move to the pressure sensor 214 on that side to reach the preset value, and the electric telescopic rod 24 stops retracting, thereby controlling the lifting plate 27 to be accurately positioned to the optimal lifting position, thereby avoiding deviations in the lifting position due to external factors, resulting in re-construction and reduced construction efficiency.

[0032] like Fig.10 As shown, the anti-deflection unit 3 includes a slider 31, a telescopic motor 32, a support plate 33, an anti-deflection rod 34, an anti-deflection plate 35, an electromagnet 1 36, an electromagnet 2 37, a straight rod 38, a conductive sheet 39 and a vertical tube 310. The slider 31 is fixedly mounted on the outer surface of the mounting box 25, the slider 31 is slidably mounted on the slide rail 11, the fixed end of the telescopic motor 32 is fixedly mounted on the mounting frame 1, the telescopic end of the telescopic motor 32 is fixedly connected to the slider 31, the support plate 33 is fixedly mounted on the mounting frame 1, and the vertical tube 310 is fixedly mounted on the mounting frame 1. The cylinder 310 is fixedly mounted on the support plate 33, the anti-deflection rod 34 is slidably mounted in the vertical cylinder 310, the anti-deflection rod 34 is fixedly connected to the electromagnet 2 37 at one end close to the horizontal foundation, the anti-deflection rod 34 is fixedly connected to the anti-deflection plate 35 at one end away from the horizontal foundation, the electromagnet 1 36 is fixedly mounted on the inner surface of the vertical cylinder 310 at one end close to the horizontal foundation, the electromagnet 1 36 is electrically connected to the conductive block 29, the electromagnet 2 37 is slidably connected to the straight rod 38, and a plurality of conductive sheets 39 are evenly arranged on the straight rod 38.

[0033] When 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 can transport items. During transportation, if the items are affected by wind factors and cause the items to deviate in the left and right directions, or if the items and the lifting plate 27 produce relative movement during transportation, causing the items to deviate in the front and back directions, due to the change in the center of gravity of the items, on the one hand, the squeezing plate 210 is lowered to contact the conductive block 29 while squeezing the conductive block 29 to move downward along the fixed column 216, squeezing the telescopic spring 28 while the effective number of turns of the small coil 215 is gradually reduced, and the current transmitted to the electromagnet 36 through the small coil 215 is gradually increased, and the magnetic field of the electromagnet 36 is The anti-deflection plate 35 is driven by the anti-deflection rod 34 to push the electromagnet 2 37 to move downward along the straight rod 38 in the vertical tube 310 while contacting the conductive sheet 39, so that the electromagnet 2 37 generates magnetism, and the electromagnet 2 37 is pushed to move upward under the action of the electromagnet 1 36, and the anti-deflection plate 35 is driven by the transmission action of the anti-deflection rod 34 to push the end of the lifting plate 27 that is deflected downward to be lifted and reset upward, so that the extrusion plate 210 is out of contact with the conductive block 29, thereby correcting the center of gravity of the deflected object and readjusting it, realizing the deviation correction of the objects, avoiding the problem of objects falling during transportation, affecting the construction efficiency and avoiding safety hazards.

[0034] like Fig. 9 As shown, the conductive block 29 is composed of a first conductive block 291 at one end away from the telescopic motor 32 and a second conductive block 292 at one end close to the telescopic motor 32 .

[0035] When the object is offset in the front-to-back direction, the two first conductive blocks 291 or the two second conductive blocks 292 are squeezed down by the corresponding squeezing plate 210, and the small coil 215 transmits current to the electromagnet 1 36 through the two first conductive blocks 291 or the two second conductive blocks 292, so that the electromagnet 1 36 is magnetic and pushes the electromagnet 2 37 to move upward, so that the anti-deflection plate 35 corrects the offset of the object and prevents the object from being offset. When the object is offset in the left-to-right direction, the first conductive block 291 and the second conductive block 292 are squeezed down, and the small coil 215 transmits current to the electromagnet 1 36 through the first conductive block 291 and the second conductive block 292, so that the electromagnet 1 36 is magnetic and pushes the electromagnet 2 37 to move upward, so that the anti-deflection plate 35 corrects the offset of the object. In order to avoid problems with one of the currents, the other current can be partially compensated to maintain a certain magnetism of the electromagnet 1 36, thereby improving the stability and reliability of the system.

[0036] like Figure 8 As shown, the end of the small coil 215 away from the lifting plate 27 is a current input port.

[0037] When the conductive block 29 is squeezed and descends, the effective number of turns of the small coil 215 decreases as the descending distance, and the current increases, thereby gradually increasing the magnetism of the electromagnet 36. The more the object is deflected, the stronger the magnetism generated by the electromagnet 36, thereby ensuring that the resetting of the object is not affected.

[0038] like Fig.10 As shown, in the vertical direction, the current input into the plurality of conductive sheets 39 decreases step by step from bottom to top.

[0039] When the squeezing plate 210 gradually squeezes the conductive block 29 to move downward, the effective number of turns of the small coil 215 gradually decreases, and the current delivered to the electromagnet 1 36 gradually increases, and the magnetism of the electromagnet 1 36 gradually increases. At the same time, the lifting plate 27 squeezes the anti-deflection plate 35 to move downward, so that the anti-deflection rod 34 pushes the electromagnet 2 37 to move downward gradually, and the current passed through the conductive sheet 39 gradually decreases, so that the magnetism of the electromagnet 2 37 gradually decreases, and the object is buffered when it is offset to avoid the object falling due to a large offset. In the process of adjusting the offset and resetting the object, the magnetism of the electromagnet 1 36 increases with the increase of the effective number of turns of the small coil 215. The magnetism of electromagnet 1 36 and electromagnet 2 37 gradually decreases, while the magnetism of electromagnet 2 37 gradually increases as the current of conductive sheet 39 increases during the rising process. By accurately adjusting the increase and decrease of the magnetism of electromagnet 1 36 and electromagnet 2 37, the direction and size of the corrective force can be accurately controlled. In the process of correcting the center of gravity deviation, the rate and amplitude of the magnetism change of electromagnet 1 36 and electromagnet 2 37 are dynamically adjusted according to the weight of the object and the degree of center of gravity deviation, 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, causing a secondary deviation of the object.

[0040] like Figure 4 As shown, the electromagnet 1 36 and the electromagnet 2 37 have the same polarity.

[0041] In order to reset the offset object, the polarities of the electromagnet 1 36 and the electromagnet 2 37 are set to be the same.

[0042] like Figure 2 , Fig.10 As shown, the hydraulic cylinder 21 is electrically connected to the external controller, and the conductive sheet 39 is electrically connected to the external controller.

[0043] In order to facilitate the timely response and automation of the device, the items can be automatically and timely dynamically adjusted during transportation, thereby improving the anti-drift performance of the device.

[0044] Working principle of the present invention: When an 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. The telescopic part of the hydraulic cylinder 21 drives the magnet 22 to move upward. At this time, 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. The memory spring 212 is energized and contracts at this time, thereby pulling the bending rod 213 and the pressure sensor 214 to move synchronously toward 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 size at this location and continues to transmit 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 When the preset value is reached, it is determined that the pushing position of the lifting plate 27 has not reached the standard. At this time, the controller controls the electric telescopic rod 24 to extend, and pushes the hydraulic cylinder 21 to move to the pressure sensor 214 on that side to reach the preset value, and 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 has not reached the standard. At this time, the controller controls the electric telescopic rod 24 to retract, and pulls the hydraulic cylinder 21 to move to the pressure sensor 214 on that side to reach the preset value, and the electric telescopic rod 24 stops retracting, thereby controlling the lifting plate 27 to be accurately positioned to the optimal lifting position, thereby avoiding deviations in the lifting position due to external factors, resulting in re-construction and reduced construction efficiency.

[0045] When an 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. The telescopic part of the hydraulic cylinder 21 drives the magnet 22 to move upward. At this time, 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. The memory spring 212 is energized and contracts at this time, thereby pulling the bending rod 213 and the pressure sensor 214 to move synchronously toward 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 size at this location and continues to transmit 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 has not reached 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 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 has not reached the standard. At this time, the controller controls the electric telescopic rod 24 to retract, and pulls the hydraulic cylinder 21 to move until the pressure sensor 214 on this side reaches the preset value, and the electric telescopic rod 24 stops retracting, thereby controlling the lifting plate 27 to be accurately positioned to the optimal lifting position, thereby In order to avoid the deviation of the lifting position caused by external factors, which would cause the construction efficiency to be reduced due to re-construction, when the extrusion plate 210 gradually squeezes the conductive block 29 to move downward, the effective number of turns of the small coil 215 gradually decreases, and the current delivered to the electromagnet 36 gradually increases, and the magnetism of the electromagnet 36 gradually increases. At the same time, the lifting plate 27 squeezes the anti-deflection plate 35 to move downward, so that the anti-deflection rod 34 pushes the electromagnet 2 37 to move downward gradually, and the current passed through the conductive sheet 39 gradually decreases, so that the magnetism of the electromagnet 2 37 gradually decreases, and the objects are buffered when they are offset to avoid the objects falling due to a large offset. In the process of adjusting the offset and resetting the objects, the magnetism of the electromagnet 36 The magnetism of electromagnet 1 36 and electromagnet 2 37 gradually decreases as the effective number of turns of small coil 215 increases, while the magnetism of electromagnet 2 37 gradually increases as the current of conductive sheet 39 increases during the rising process. By accurately adjusting the increase and decrease of the magnetism of electromagnet 1 36 and electromagnet 2 37, accurate control of the direction and size of the corrective force can be achieved. In the process of correcting the center of gravity deviation, the rate and amplitude of the magnetic change of electromagnet 1 36 and electromagnet 2 37 are dynamically adjusted according to the weight of the object and the degree of center of gravity deviation, 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, causing secondary deviation of the object.
