Description

Technical Field

[0001] The invention belongs to the technical field of tire wear detection for tire cranes, and in particular relates to a tire self-detection device and method for tire cranes based on a steering wear section. Background Art

[0002] Tire cranes are large lifting equipment used for container lifting in ports. Compared with rail-mounted cranes, they are more flexible to use because they have tires. When a tire crane is lifting containers in a port, the route it takes is almost always right-angle turns except for the straight section. For example, the shortest route is to lift a container from a container pile, then go straight to a certain point, make a right-angle turn at that point, then continue straight to the target container pile, put the container down, and then return along the original route to lift the next container. When making a right-angle turn, many times, such as when operating in a container stacking area, the tire crane does not have space to complete the right-angle turn while moving. It can only stop at the point and rotate the tire 90° on the spot to complete the right-angle turn. Due to the heavy weight of the tire crane, if the wear during this rotation on the spot is concentrated on a certain part of the tire, the service life of the tire will be significantly shortened.

[0003] In this regard, there are currently methods such as Publication (Announcement) No. CN2517723Y that lifts up the entire tire crane by setting a lifting component, and then turns after the tire is vacated, and there are also methods such as Publication (Announcement) No. CN221093527U that sets a slewing part on the ground, allowing the tire crane to move to an area with a slewing part, and then turn after the tire is on the slewing part. Both methods have the problem of reducing the operating efficiency of the tire crane in order to extend the service life of the tire. The former method requires the entire tire crane to be supported each time it turns, which will cause part of the time when the tire crane is operating to be occupied by supporting and retracting the legs, thereby reducing the lifting efficiency. At the same time, the lifting component also requires additional equipment costs and maintenance costs. The latter method restricts the route of the tire crane. The tire crane must move to the area of ​​the slewing part before using the slewing part, which is equivalent to being restricted by the track, and the route cannot be freely planned, which reduces flexibility.

[0004] Therefore, in order to solve the problem that the current method of extending the life of the tires of the tire crane is too extensive and leads to reduced operating efficiency of the tire crane, the present application proposes a tire self-inspection device and method for the tire crane based on the steering wear section. Summary of the invention

[0005] The purpose of the present invention is to provide a tire self-checking device and method for a tire crane based on a steering wear section to solve the problem of

[0006] Currently, tire cranes cannot detect and adjust the part of the tire that is subject to wear and tear, and can only roughly protect the entire tire, which leads to a technical problem that the tire crane's operating efficiency is reduced.

[0007] In order to solve the above technical problems, the present invention provides a tire self-test device for a tire crane based on steering wear segments, comprising: a test base plate, which is connected to the wheel hub of the tire crane so as to be concentric with and synchronously rotate with the tire; a plurality of tire segment arc strips connected end to end and surrounding a tire segment circular ring are arranged on the outer disk surface of the test base plate so as to divide the tire of the tire crane into a plurality of segments, and each tire segment arc strip increases in height along the circumference of the test base plate; a test arm, which is connected to the body of the tire crane so as to align the wear segment identification component thereon with the lowest point of the tire segment circular ring; a steering test arm, which is connected to the body of the tire crane so as to align the wear segment identification component thereon with the lowest point of the tire segment circular ring; a steering test arm, which is connected to the wheel hub ... A detection component is arranged on the detection base plate and is suitable for sending an in-situ right-angle rotation signal to the control module immediately after detecting the in-situ right-angle rotation of the tire; the control module is suitable for obtaining the height signal of the tire segment arc bar located at the lowest point at this time through the wear segment identification component after receiving the in-situ right-angle rotation signal, so as to increase the number of steering wear for the corresponding tire segment through the wear segment recording component, so that when performing round-trip lifting with in-situ right-angle rotation, the tire segment with the least accumulated steering wear number can be landed at the in-situ right-angle rotation position through the segment insertion component.

[0008] On the other hand, the present invention also provides a tire self-inspection method for a tire crane based on a steering wear segment, comprising: the tire self-inspection device for a tire crane based on a steering wear segment as described above; detecting the right-angle rotation of the tire in situ by a steering detection component, and immediately sending a right-angle rotation signal in situ to a control module when the tire rotates in situ at a right angle; obtaining the height signal of the tire segment arc bar located at the lowest point when the tire rotates in situ at a right angle by a wear segment identification component, and increasing the number of steering wear times for the corresponding tire segment by a wear segment recording component; when performing round-trip lifting with right-angle rotation in situ, the tire segment with the least accumulated steering wear times is landed at the right-angle rotation in situ by an insertion segment component.

[0009] The beneficial effect of the present invention is that the tire self-detection device for a tire crane based on a steering wear segment provided by the present invention can be concentric with the tire and rotate synchronously after the detection base plate is installed on the wheel hub of the tire crane, so that a plurality of tire segment arc strips on the outer disk surface of the detection base plate can represent the corresponding segments of the tire of the tire crane. In this way, after the control module detects the right-angle rotation of the tire in situ through the steering detection component, it can obtain the tire segment arc strip located at the lowest point at this time by aligning the wear segment identification component at the lowest point of the tire segment ring, and add a steering wear to the corresponding tire segment through the wear segment recording component. The number of wears can be calculated, and then when the tire crane performs a round-trip lifting operation with a right-angle rotation on the spot, that is, when it is suitable for inserting sections, the tire section with the least accumulated steering wear can be preferentially landed at the right-angle rotation on the spot through the segment insertion assembly, thereby realizing the detection and regulation of the steering wear borne by each section of the tire of the tire crane, so that each section of the tire of the tire crane is evenly borne by the steering wear, which can extend the service life of the tire of the tire crane. In addition, the detection and regulation of the steering wear borne by each section of the tire of the tire crane by the self-inspection device can be carried out together with the travel of the tire crane, which has little impact on the operation of the tire crane.

Based on the embodiments of the present invention, all other embodiments of ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example

[0033] like Figure 1 As shown, the present invention provides a tire self-test device for a tire crane based on a steering wear section, comprising: a test base plate 100, which is connected to the wheel hub 10 of the tire crane so as to be concentric with the tire and rotate synchronously; Figure 8 and Fig. 9 The outer disk surface of the detection base 100 is provided with a plurality of tire segment arc strips 210 connected end to end and surrounding a tire segment circular ring 200, so as to divide the tire of the tire crane into a plurality of segments, and each tire segment arc strip 210 increases in height along the circumference of the detection base 100; the detection arm 300 is connected to the body of the tire crane so that the wear segment identification component 400 thereon is aligned with the lowest point of the tire segment circular ring 200; combined with Fig.10 , the steering detection component 500 is arranged on the detection base plate 100, and is suitable for sending a right-angle rotation signal to the control module immediately after detecting the right-angle rotation of the tire in place; the control module is suitable for obtaining the height signal of the tire segment arc bar 210 located at the lowest point at this time through the wear segment identification component 400 after receiving the right-angle rotation signal in place, so as to increase the steering wear times for the corresponding tire segment through the wear segment recording component 600, so that when performing round-trip lifting with right-angle rotation in place, the tire segment with the least accumulated steering wear times can be grounded at the right-angle rotation in place through the segment insertion component 700. In at least one embodiment, the control module can be, but is not limited to, a PLC module.

[0034] In the tire self-test device for a tire crane based on steering wear segments, after the detection base plate 100 is installed on the wheel hub 10 of the tire crane, it can be concentric with the tire and rotate synchronously, so that the several segments of tire segment arc strips 210 on the outer disk surface of the detection base plate 100 can represent the corresponding segments of the tire of the tire crane. In this way, after the control module detects the right-angle rotation of the tire in situ through the steering detection component 500, it can obtain the tire segment arc strip 210 located at the lowest point at this time by aligning the wear segment identification component 400 with the lowest point of the tire segment ring 200, and increase the steering wear times for the corresponding tire segment through the wear segment recording component 600, so as to perform When the tire crane performs a reciprocating lifting operation with a right-angle rotation on the spot, that is, it is suitable for an operation of inserting a segment, the segment insertion assembly 700 can be used to preferentially allow the tire segment with the least accumulated steering wear times to touch the ground at the right-angle rotation on the spot, so as to balance the number of steering wear times of each tire segment, thereby realizing the detection and regulation of the steering wear borne by each segment of the tire of the tire crane, so that each segment of the tire of the tire crane bears the steering wear evenly, which can extend the service life of the tire of the tire crane, and the detection and regulation of the steering wear borne by each segment of the tire of the tire crane by the self-inspection device can be carried out together with the travel of the tire crane, with little impact on the operation of the tire crane.

[0035] like Figure 2 and Figure 3 As shown, in at least one embodiment, the insert segment assembly 700 may include: a steering column gear 710, which is clamped on the steering column 20 of the cab; the steering column gear 710 may be but is not limited to being clamped with the steering column 20 in the form of being inserted into the steering column 20 and then keyed; an insert segment transmission gear 720, which is arranged in the insert segment box 730 and meshes with the steering column gear 710; a gear seat may be provided on the inner top surface of the insert segment box 730 for mounting the insert segment transmission gear 720; an insert segment steering motor 740, which is arranged on the clutch lifting platform 750, so that when the driver performs a round-trip lifting operation, the insert segment is triggered through the wear segment recording assembly 600, and after the control module detects a change in the height signal through the wear segment identification assembly 400, the insert segment clutch electric cylinder 760 is controlled to raise the clutch lifting platform 750, so that the insert segment steering motor 740 is engaged with the insert segment transmission gear 720 for transmission, refer to Figure 5 The steering column 20 is first turned outward by 60° through the inserted steering motor 740, and then returned to the center after the tire segment rotates one section, and then turned inward by 60° after the tire segment rotates nine sections, and then returned to the center after the tire segment rotates one section, and an additional tire segment is inserted. The corresponding tire segment is additionally inserted so that the tire segment with the least accumulated steering wear times touches the ground at the right-angle rotation position.

[0036] In at least one embodiment, Figure 4As shown, the bottom surface of the insert-stage transmission gear 720 and the top surface of the drive disk of the insert-stage steering motor 740 can be provided with an engagement ring 810 with an anti-slip groove on the contact surface to perform engagement transmission.

[0037] In at least one embodiment, Fig. 9 As shown, there are ten tire segment arc strips 210 to divide the tire of the tire crane into ten segments; the number of tire segment arc strips 210 is based on the number of tire segments that are slightly longer than a tire segment that touches the ground when the tire crane lifts the heaviest container to be lifted. For example, the tire segment that is evenly divided is 10 cm longer than a tire segment that touches the ground. Figure 5 The tire with ten tire segments on the left side, that is, the middle part of the tire segment with serial number 0 is the best for ground contact; the wear segment recording component 600 may include: Figure 2 As shown, the recording box 610, reference Figure 6 and Figure 7 , which is provided with ten electric push rods 620 and ten first pen-type displacement sensors 630; one electric push rod 620 corresponds to one first pen-type displacement sensor 630, and corresponds to one tire segment arc strip 210, that is, corresponds to one tire segment; Figure 6 and Figure 7 As shown, the push rod extension end 621 of each electric push rod 620 is connected to a synchronization rod 640; Figure 6 and Figure 7 As shown, the tail of each synchronization rod 640 is connected to the first pen-type displacement sensor extension end 631 of a first pen-type displacement sensor 630, and the front end is connected to the wear number indicator block 650; Figure 6 As shown, the recording box 610 is provided with an indicating through hole 611 for exposing the corresponding wear times indicating block 650; the control module is adapted to obtain the height signal of the tire segment arc strip 210 located at the lowest position at this time through the wear segment identification component 400 after receiving the in-situ right-angle rotation signal, so as to control the corresponding electric push rod 620 to raise the push rod extension end 621 by one unit, so as to increase the number of steering wear times for the corresponding tire segment.

[0038] like Figure 7As shown, in at least one embodiment, the self-test device triggers the insertion segment in a semi-automatic manner, that is, a trigger button 660 is provided below each indicating through hole 611 of the recording box 610, so that when the driver performs a round-trip lifting operation, according to whether there are other vehicles in the direction of travel, the insertion segment is triggered by pressing the trigger button 660 below the lowest wear count indicator block 650, and the control module is suitable for automatically inserting the corresponding tire segment through the insertion segment assembly 700 based on the difference in height between the first pen-type displacement sensor extension end 631 corresponding to the lowest wear count indicator block 650 and the first pen-type displacement sensor extension end 631 corresponding to the second lowest wear count indicator block 650, so that the tire segment with the least accumulated steering wear times touches the ground at a right-angle rotation position corresponding to the original position.

[0039] like Figure 8 As shown, in at least one embodiment, the wear segment identification component 400 may include: a second pen-type displacement sensor 410, which is arranged in the detection arm 300, aligned with the lowest point of the tire segment ring 200, and electrically connected to the control module; a fitting spring 420, one end of which is arranged on the second pen-type displacement sensor 410, and the other end is connected to the second pen-type displacement sensor extension end 411, so that the second pen-type displacement sensor extension end 411 and the tire segment ring 200 remain in contact.

[0040] like Figure 8 As shown, in order to ensure that the second stylus displacement sensor extension end 411 slides smoothly on each tire segment arc strip 210 , the connecting part of each tire segment arc strip 210 is provided with a displacement sensor extension end sliding chamfer 211 .

[0041] In at least one embodiment, the steering detection component 500 may include: an angle sensor 510, which is arranged on the detection base plate 100 and electrically connected to the control module. The angle sensor 510 is at least an angle sensor that can obtain the angles of two axes, one of which is parallel to the tire axis, and one of which is parallel to the tire rotation axis. When the angle corresponding to the axis parallel to the tire axis remains unchanged, it means that the tire crane has stopped. When the angle corresponding to the axis parallel to the tire rotation axis changes by 90°, it means that the tire has made a right-angle rotation. If both occur at the same time, it means that the tire crane has made a right-angle rotation in place. The control module can detect that the tire crane has made a right-angle rotation in place through the angle sensor 510.

[0042] In at least one embodiment, the detection base plate 100 is connected to the wheel hub 10 of the tire crane as follows. For a tire crane with a wheel hub bolt, such as Figure 8As shown, the inner disk surface of the detection base plate 100 is connected to a hub docking rod 110; the hub docking rod 110 is provided with a hub bolt hole, which is suitable for docking the hub bolt and allowing the hub bolt to extend out of the hub bolt hole, so as to screw on the hub docking nut 120, thereby installing the detection base plate 100 on the wheel hub 10 of the tire crane.

[0043] The working principle of the tire self-checking device for a tire crane based on the steering wear section is described below.

[0044] After the tire crane is started, the detection base plate 100 and the tire are concentric and rotate synchronously. Figure 8 Whenever the tire crane makes a right-angle rotation in situ, the control module can detect that the tire crane has made a right-angle rotation in situ through the angle sensor 510 in the aforementioned manner. When the control module detects that the tire crane has made a right-angle rotation in situ, the second pen-type displacement sensor extension end 411 abuts against the tire segment arc strip 210 corresponding to the tire segment that is subjected to steering wear at this time. According to the height of the tire segment arc strip 210, the second pen-type displacement sensor extension end 411 has a specific extension distance, which is equivalent to the control module being able to obtain the height signal of the tire segment arc strip 210 through the second pen-type displacement sensor extension end 411. Afterwards, based on an electric push rod 620 corresponding to a first pen-type displacement sensor 630, and corresponding to a tire segment arc strip 210, that is, corresponding to a tire segment, refer to Figure 7 The control module controls the electric push rod 620 corresponding to the tire segment arc strip 210 to rise one unit, and increases the number of steering wear times for the tire segment that is subject to steering wear at this time.

[0045] Afterwards, whenever the tire crane performs a round-trip lifting operation, the driver can trigger the insertion segment by pressing the trigger button 660 below the lowest wear count indicator block 650 according to whether there are other vehicles in the direction of travel. Afterwards, the control module uses the difference between the height of the first pen-type displacement sensor extension end 631 corresponding to the lowest wear count indicator block 650 and the height of the first pen-type displacement sensor extension end 631 corresponding to the second lowest wear count indicator block 650 to insert an additional corresponding tire segment through the insertion segment assembly 700, so that the tire segment with the least accumulated steering wear times touches the ground at the original right-angle rotation position for a corresponding number of times.

[0046] The specific principle of inserting segments is as follows. Figure 5, where the left side is a tire divided into ten segments, and represented by numbers from 0 to 9, and the solid line on the right side is the order in which the tire segments touch the ground before driving to the original right-angle turn during the round-trip lifting operation. The top segment represents the tire segment that touches the ground when driving to the original right-angle turn. Assuming that the tire is a new tire with only the tire segment with number 1 experiencing one steering wear, if it goes straight along the solid line, the tire segment that touches the ground when driving to the original right-angle turn this time is still the tire segment with number 1, and if the two stacks of containers in the round-trip lifting operation remain unchanged, the tire crane also keeps driving along the original route, and the subsequent driving to the original right-angle turn several times The tire segment that touches the ground when the tire turns at a right angle will always be the tire segment with the serial number 1. The tire segment with the serial number 1 will bear more steering wear than other tire segments. Now, if the road conditions permit, when the driver presses the trigger button 660 corresponding to the tire segment with the serial number 1, the control module calculates the difference between the height of the first pen-type displacement sensor extension end 631 corresponding to the lowest wear number indicator block 650 and the height of the first pen-type displacement sensor extension end 631 corresponding to the second lowest wear number indicator block 650, which is one unit here (because it is assumed that the tire is a new tire that has only the tire segment with the serial number 1 bearing one steering wear), refer to Figure 4 The control module raises the clutch lifting platform 750 through the plug-in section clutch electric cylinder 760, so that the plug-in section steering motor 740 is engaged with the plug-in section transmission gear 720 for transmission, and then the plug-in section steering motor 740 is used to Figure 5The dotted line on the right side indicates that when the second stylus displacement sensor extension end 411 slides onto a certain displacement sensor extension end sliding chamfer 211 during the travel, for example, when the displacement sensor extension end sliding chamfer 211 between the tire segment arc strip 210 corresponding to the tire segment with serial number 0 and the tire segment arc strip 210 corresponding to the tire segment with serial number 1, the steering column 20 is immediately turned outward by 60°, and after the second stylus displacement sensor extension end 411 detects that the tire segment has rotated one section, it returns to the center, and then after the second stylus displacement sensor extension end 411 detects that the tire segment has rotated nine sections, it returns to the center. The tire is turned 60° inward, and then returned to the original position after the tire section rotates for a section. In this way, the tire section that touches the ground when driving to the right-angle rotation position is adjusted to the tire section with serial number 2, which is equivalent to inserting a section in front of the tire section with serial number 1 that originally bears steering wear, so that the tire section that bears steering wear becomes the tire section with serial number 2. In the subsequent process, the tire sections with serial numbers 3, 4, 5...9 can be successively made into the tire sections that touch the ground when driving to the right-angle rotation position in the original position, so that the number of times each tire section bears steering wear when the tire crane is lifting back and forth between the two piles of containers is balanced. Among them, the 60° direction is hit because it is hit during the movement of the tire crane, and the friction with the road surface is small. In addition, it is the junction area of ​​the tire section. If the tire section divided according to the above is slightly longer than the tire section that touches the ground, it can be ensured that the tire section that touches the ground when hitting the 60° direction is the junction area of ​​the tire section that does not bear steering wear, so the service life of the tire of the tire crane is minimally affected. Moreover, by inserting the sections in this way, the extra lateral movement space required by the tire crane is also very small. The tire crane only needs to move a short distance to the side. The self-inspection device can detect and regulate the steering wear of each section of the tire of the tire crane together with the movement of the tire crane, which has little impact on the operation of the tire crane.

[0047] However, in actual lifting operations, the tire crane often needs to move to other container piles after lifting a few containers in the two container piles. It is difficult for the tires to bear steering wear in the order of serial numbers 0, 1, 2...9. By setting the wear segment recording component 600, it can be accepted that some tire segments bear more steering wear and some tire segments bear less steering wear during a certain period of time. For example, after going back and forth between the upper two container piles, the number of steering wears of the tire segment with serial number 0 is less than that of other tire segments, and becomes the smallest. The driver only needs to pass the corresponding tire segment during the straight section during the round-trip lifting operation between the lower two container piles with longer straight sections. The trigger button 660 is used to insert a segment. The control module can obtain the number of steering wears that the tire segment with number 0 needs to bear through the difference between the height of the first pen-type displacement sensor extension end 631 corresponding to the tire segment with number 0 and the height of the first pen-type displacement sensor extension end 631 corresponding to the second lowest wear times indicator block 650, and perform a corresponding insertion before each right-angle turn at the original location during the round-trip lifting operation between the next two container stacks, so that each time the tire segment touches the ground at the original right-angle turn, the tire segment with number 0 is the tire segment that touches the ground, until the tire segment with number 0 has compensated for the number of steering wears. The wear segment recording component 600 can also be reset in time by the electric push rod 620 completely retracting the push rod extension end 621 whenever all the first pen-type displacement sensor extension ends 631 are aligned. Figure 2 As shown, an emergency stop button 820 may also be provided on the segment insertion box 730 for stopping the segment insertion at any time. After the emergency stop, the wear segment recording component 600 may also normally record the tire segment that is subject to steering wear.

[0048] In at least one embodiment, a tire self-inspection method for a tire crane based on a steering wear segment is also provided, comprising: a tire self-inspection device for a tire crane based on a steering wear segment as described above; detecting the tire's right-angle rotation in situ by means of a steering detection component 500, and immediately sending a right-angle rotation in situ signal to a control module when the tire rotates in situ at a right angle; obtaining a height signal of a tire segment arc bar 210 located at the lowest point when the tire rotates in situ at a right angle by means of a wear segment identification component 400, and increasing the number of steering wear times for the corresponding tire segment by means of a wear segment recording component 600; when performing round-trip lifting with right-angle rotation in situ, the tire segment with the least accumulated steering wear times is landed at the right-angle rotation in situ by means of an insertion segment component 700.

[0049] The tire self-inspection method of the tire crane based on the steering wear section and the technical effects produced have been described above and will not be repeated here.

[0050] In summary, in the tire self-test device of the tire crane based on the steering wear segment, the detection base plate 100 can be conveniently installed on the tire of the existing tire crane through the hub docking rod 110 and the hub docking nut 120, and the steering column gear 710 in the insert segment assembly 700 can also be conveniently installed on the steering column 20 of the existing tire crane. The other components of the insert segment assembly 700 and the wear segment recording component 600 can also be directly installed in the cab. Therefore, the self-test device is compatible with most of the existing tire cranes without major modifications to the existing tire cranes. On this basis, after the detection base plate 100 is installed on the wheel hub 10 of the tire crane, it can be concentric with the tire and rotate synchronously, so that the several segments of the tire segmented arc strips 210 on the outer disk surface of the detection base plate 100 can represent the corresponding segments of the tire of the tire crane, so that the control module detects the right-angle rotation of the tire in situ through the steering detection component 500. Afterwards, the tire segment arc strip 210 located at the lowest point can be obtained by aligning the wear segment identification component 400 with the lowest point of the tire segment ring 200, and the number of steering wear times for the corresponding tire segment can be increased by the wear segment recording component 600. Then, when the tire crane performs a round-trip lifting operation with a right-angle rotation in situ, that is, when it is suitable for inserting segments, the segment insertion component 700 can be used to preferentially make the tire segment with the least accumulated steering wear times touch the ground at the right-angle rotation in situ, so as to balance the number of steering wear times of each tire segment, thereby realizing the detection and regulation of the steering wear borne by each segment of the tire of the tire crane, so that each segment of the tire of the tire crane is evenly subjected to the steering wear, which can extend the service life of the tire of the tire crane, and the detection and regulation of the steering wear borne by each segment of the tire of the tire crane by the self-inspection device can be carried out together with the travel of the tire crane, which has little impact on the operation of the tire crane.
