Description

Technical Field

[0001] The invention relates to the technical field of material handling equipment, in particular to an automatic correction mechanism for the running state of a traveling wheel of a vehicle. Background Art

[0002] In the modern industrial production system, the crane is a key equipment for material handling. Its operating stability, safety and efficiency directly affect the smoothness and economy of the entire production process. The crane running wheels are the core components that bear the weight of the crane and realize its movement along the track. Its operating status plays a decisive role in the overall performance of the crane.

[0003] Traditional traveling wheels face many problems in actual operation:

[0004] In terms of the synchronization of travel on both sides, due to factors such as differences in drive motor selection, discreteness of drive circuit parameters, and dynamic changes in load during lifting, the speeds of the travel motors on both sides are often inconsistent, which causes the vehicle body to shift during operation and deviations in the material handling path. This not only seriously reduces the efficiency of the handling operation, but also causes excessive pressure on one side of the track, accelerating track wear, significantly shortening the track service life, and increasing equipment maintenance costs and downtime.

[0005] Regarding the problem of running wheel deflection, it is difficult to achieve absolutely high precision in track installation. In addition, the structural fatigue deformation caused by long-term and frequent operation of the vehicle makes the running wheel very easy to deflect. Once the running wheel is deflected, the contact stress distribution between it and the track is seriously uneven, causing the wear of the local area of ​​the running wheel to increase. As the wear continues, the running track of the running wheel further deviates from the normal path. In severe cases, it may even cause the running wheel to derail, posing a huge threat to the life safety of production workers and corporate property.

[0006] In addition, in a complex industrial production environment, the eccentric torque generated by lifting materials with irregular center of gravity, or when encountering severe external weather conditions such as strong winds, the traveling wheels of the crane may also shift sideways. This lateral shift destroys the original stable operating state of the crane and increases the risk of collision between the crane and surrounding equipment, thereby affecting the orderly production of the entire production workshop and even causing a chain of safety accidents.

[0007] In summary, a mechanism for automatically correcting the running state of a vehicle's traveling wheels is proposed. Summary of the invention

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. For the automatic correction mechanism for the running state of the traveling wheels of the overhead crane in the present invention, a torque detector and a first driving motor are installed on the bilateral walking beams. The first driving motor can, to a certain extent, automatically adapt to the slight unevenness of the walking beams and the running deviation of the first traveling wheels, reducing the influence of the unevenness of the walking beams on the running of the overhead crane. The torque detector monitors the torque of the two first traveling wheels in real time and feeds the torque data back to the frequency converter. Through the intelligent comparison and operation program built into the PLC, the torque data of the two first traveling wheels are compared and analyzed in real time. According to the analysis results, the output torque of the frequency converter is dynamically adjusted to achieve the precise synchronous operation of the two walking structures. When it is detected that there is a deviation in the two-side walking, the system can quickly start the adaptive deviation correction mechanism, and automatically correct the walking deviation by adjusting the rotation speed and torque of the first driving motor, effectively improving the stability and straightness of the running of the overhead crane.

When it is judged that the crane has a skew or lateral movement phenomenon, the PLC adjusts the output speed of the frequency converter according to the preset correction strategy to achieve intelligent correction of the running posture of the crane, which can realize all-round and real-time monitoring and precise correction of the running state of the traveling wheels of the crane, effectively improving the safety and reliability of the crane operation.

Specific embodiments

[0038] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0039] The present invention provides the following preferred embodiments:

[0040] Embodiment 1, as Figures 1 - 8 shown, an automatic correction mechanism for the running state of a traveling crane wheel includes a cross beam 12 located below two walking beams 11, and further includes a first walking mechanism, a second walking mechanism, a detection mechanism, a hoisting mechanism and a balance mechanism;

[0041] The first walking mechanism includes two connecting arms 13 and a plurality of first moving components. The two connecting arms 13 are symmetrically installed on both sides of the top end of the cross beam 12. Every four first moving components are symmetrically installed on one connecting arm 13. The four first moving components on each connecting arm 13 are symmetrically arranged on both sides of one walking beam 11;

[0042] The detection mechanism includes a plurality of torque detectors 19 and a plurality of second gears 18. Each torque detector 19 and a second gear 18 are installed on one first moving component;

[0043] The second traveling mechanism is installed on the cross beam 12. The second traveling mechanism includes two moving plates 22, a plurality of connecting rods 23 and a second moving assembly. The two moving plates 22 are symmetrically arranged on both sides of the cross beam 12. Each connecting rod 23 is located below the cross beam 12 and fixed between the two moving plates 22. The second moving assembly is installed on the two moving plates 22;

[0044] The hoisting mechanism and the balancing mechanism are respectively installed on one side of the two moving plates 22 away from each other.

[0045] As Figures 1 - 8 shown, each moving assembly includes a side plate 14, a first driving motor 16, a first transmission component and two first traveling wheels 15. The side plate 14 is fixed to the top of the connecting arm 13. The two first traveling wheels 15 are symmetrically rotatably arranged on one side of the side plate 14. Each first traveling wheel 15 is lapped on the traveling beam 11. The first driving motor 16 is installed on the side of the side plate 14 away from the first traveling wheels 15. The first transmission component is located between the first driving motor 16 and the two first traveling wheels 15;

[0046] Through the first transmission component, when the first driving motor 16 works, it can drive the two first traveling wheels 15 to rotate, so that the crane can travel on the traveling beam 11;

[0047] Specifically, the first driving motor 16 adopts a high-performance rare earth permanent magnet synchronous motor design. Its rotor poles are made of rare earth permanent magnet materials with high magnetic energy product. The stator core is laminated by silicon steel sheets with high magnetic permeability and is equipped with a strong and durable aluminum alloy housing. This design gives the motor extremely high transmission efficiency, can achieve precise speed control while efficiently outputting torque, the motor has a small volume, is convenient to layout in the limited installation space of the crane, and is easy to maintain, effectively reducing the equipment maintenance difficulty and cost.

[0048] As Figures 1 - 8 shown, the torque detector 19 is located on one side of the first driving motor 16. The torque detector 19 is installed on the rotating shaft of one of the first traveling wheels 15. The laser rangefinder 20 is located on the side of the first traveling wheel 15 away from the first driving motor 16. The laser rangefinder 20 is installed on the side plate 14;

[0049] The torque detector 19 applies advanced strain gauge torque sensor technology and is tightly installed on the drive shaft of the first traveling wheel 15 to accurately monitor the torque change borne by the first traveling wheel 15 in real time. When the vehicle is running, due to factors such as the change of the walking beam 11 condition and uneven load distribution, resulting in abnormal torque fluctuations of the first traveling wheel 15, the torque detector 19 can quickly and accurately capture this change and transmit the torque data to the control system in the form of an electrical signal. The control system analyzes and processes the collected torque data, and then precisely regulates the output speed of the first drive motor 16 to achieve automatic correction of the running state of the first traveling wheel 15, ensuring the smoothness and reliability of the vehicle running;

[0050] The laser rangefinder 20 adopts high-precision pulsed laser ranging technology. By reasonably arranging the laser rangefinder 20 on the vehicle frame, it measures the relative distance between the vehicle and the traveling beam in real time. When the first traveling wheel 15 of the vehicle is offset, the distance between the vehicle and the walking beam 11 will surely change. The laser rangefinder 20 can keenly sense this distance change and quickly upload the measurement data to the control system. The control system analyzes the laser ranging data in real time. Once it determines that the offset of the first traveling wheel 15 of the vehicle exceeds the allowable range and the automatic correction system has not been started, it immediately triggers the alarm mechanism to remind the operator to intervene in time, and at the same time provides key position deviation data support for the automatic correction system.

[0051] As Figures 1 - 8 shown, the first transmission component includes a second gear 18 and two first gears 17. The two first gears 17 are respectively fixed on the rotating shafts of the two first traveling wheels 15. The second gear 18 is installed at the output end of the first drive motor 16. The second gear 18 is located between the two first gears 17, and the second gear 18 and the two first gears 17 are sequentially meshed and connected;

[0052] When the first drive motor 16 works to drive the second gear 18 to rotate, since the second gear 18 is sequentially meshed with the two first gears 17, the second gear 18 can drive the two first gears 17 to rotate when it rotates, so that the two first traveling wheels 15 rotate synchronously to achieve the walking function.

[0053] As Figures 1 - 8 shown, the second moving component includes a second drive motor 25, a second transmission component and four second traveling wheels 24. Every two second traveling wheels 24 are rotatably arranged on a moving plate 22. Each second traveling wheel 24 is lapped on the cross beam 12. The second drive motor 25 is installed on one side of one of the moving plates 22, and the second transmission mechanism is located between the second drive motor 25 and two of the second traveling wheels 24;

[0054] When the second driving motor 25 works, it can drive two of the second walking wheels 24 to rotate through the second transmission component, so that the second walking wheels 24 can walk on the cross beam 12, thereby driving the hoisting mechanism to walk, which is convenient for picking and placing materials.

[0055] As Figures 1 - 8 shown, the second transmission component has the same structure as the first transmission component;

[0056] Specifically, the second transmission component also includes a driving gear and two driven gears. The driving gear is installed at the output end of the second driving motor 25, and the two driven gears are respectively installed on the transmission shafts of the two second walking wheels 24, and the driving gear is sequentially engaged with the two driven gears. Therefore, when the second driving motor 25 works and drives the driving gear to rotate, the two second walking wheels 24 can be rotated through the two driven gears to realize walking.

[0057] As Figures 1 - 8 shown, the hoisting mechanism includes a hoisting motor 27 and an electric hoist 28. One side of a moving plate 22 is fixed with a mounting plate 30. The hoisting motor 27 is installed at the top of the mounting plate 30, and the electric hoist 28 is installed on one side of the hoisting motor 27;

[0058] The hoisting motor 27 can provide reliable power for the operation of the electric hoist 28. The electric hoist 28 adopts a planetary gear speed change and a high-strength steel wire rope lifting structure to ensure the safety and stability of the material during the lifting and lowering process.

[0059] As Figures 1 - 8 shown, the balancing mechanism includes a counterweight frame 26 and counterweight blocks 31. The counterweight frame 26 is installed on the moving plate 22 on the side far from the mounting plate 30. The counterweight frame 26 is located below the second driving motor 25, and the counterweight blocks 31 are located inside the counterweight frame 26;

[0060] During the operation of the crane, the counterweight blocks 31 inside the counterweight frame 26 can effectively offset the unbalanced forces generated by factors such as material hoisting and the asymmetry of the crane structure, maintain the balance state of the crane walking wheels, reduce equipment vibration and wear, and improve the stability and safety of the crane operation.

[0061] As Figures 1 - 8 shown, four clamping plates 21 are fixed on each connecting arm 13. Every two clamping plates 21 are located on one side of a walking beam 11. One end of each clamping plate 21 far from the connecting arm 13 is inserted into the groove of the walking beam 11, which can effectively prevent the crane from falling off the walking beam 11 and reduce the risk coefficient.

[0062] As Figures 1 - 8As shown in the figure, a plurality of support frames 29 are equidistantly arranged at the top ends of the two walking beams 11, and the two walking beams 11 are symmetrically fixed at the bottom ends of the plurality of support frames 29. By arranging the plurality of support frames 29, the walking beams 11 can be supported, which is convenient for the installation of the walking beams 11.

[0063] The specific working process of the present invention is as follows:

[0064] When the traveling crane needs to move, the controller controls the first driving motor 16 to work. When the first driving motor 16 works, it can drive the second gear 18 to rotate. Since the second gear 18 is meshed with the two first gears 17 in sequence, when the second gear 18 rotates, it can drive the two first gears 17 to rotate, so that the two first traveling wheels 15 rotate synchronously, realizing the traveling function.

[0065] When the first traveling wheel 15 needs to be corrected, the torque detector 19 first detects that the torque of the first traveling wheel 15 is abnormal and transmits the real-time torque data to the control system. The control system quickly analyzes the torque data based on the built-in intelligent algorithm, judges the deviation direction and degree of the first traveling wheel 15. Subsequently, the control system issues an instruction, and the first driving motor 16 automatically adjusts the rotation speed of the first traveling wheel 15 according to the instruction. During the rotation speed adjustment process, the torque detector 19 continuously monitors the torque change, and the laser rangefinder 20 synchronously monitors the distance change between the traveling crane and the walking beam 11, and feeds back these real-time monitoring data to the control system. The control system continuously optimizes the control strategy of the first driving motor 16 according to the feedback data until the torque data returns to the normal range, and the laser ranging data indicates that the relative position between the first traveling wheel 15 and the walking beam 11 returns to normal. At this time, the automatic correction process is completed.

[0066] That is, during the operation of the traveling crane wheels, the torque detector 19 and the laser rangefinder 20 collect torque data and distance data in real time, and synchronously transmit these data to the control system through the high-speed data transmission bus. The control system uses the deep learning algorithm to deeply analyze the collected data, accurately judge the specific deviation direction, value and operation state trend of the first traveling wheel 15. According to the analysis result, the control system issues an accurate rotation speed adjustment instruction to the first driving motor 16, realizing the automatic correction of the operation state of the first traveling wheel 15.

[0067] At the same time, through the hoisting motor 27 and the electric hoist 28, the safety and stability of the material during lifting and lowering can be ensured, the picking and placing of the material can be realized, and the picking and placing operation of the material is convenient and efficient. And during the operation of the traveling crane, the counterweight 31 can effectively offset the unbalanced force generated by factors such as material hoisting and the asymmetry of the traveling crane structure, maintain the balance state of the first traveling wheel 15, reduce equipment vibration and wear, and improve the stability and safety of the traveling crane operation.

[0068] The beneficial effects of the present invention are specifically embodied as follows.
