[0046] Example 1

[0047] See also Figure 1 This embodiment provides a sample wheel transfer device 10, which includes: a transfer platform 100, a transfer power part 200, a walking wheel group 300, a clamping power part 400 and a clamping assembly 500; the transfer power part 200 and the walking wheel group 300 are arranged on the side of the transfer platform 100 facing the track 30; the clamping power part 400 and the clamping assembly 500 are arranged on the side of the transfer platform 100 away from the track 30; the clamping power part 400 drives the clamping assembly 500 to clamp the sample wheel 20 according to the received driving instruction; the transfer power part 200 drives the walking wheel group 300 to transport the sample wheel 20 to the target position according to the received first transport instruction generated based on the clamping operation result. It should be noted that Figure 1 The area indicated by the symbol Q is used to clamp the sample wheel 20.

[0048] See also Figure 2 The track 30 is used for the sample wheel transport device 10 to travel, that is, the running wheel set 300 of the sample wheel transport device 10 can move along the track 30 under the drive of the transport power unit 200. In some other embodiments, the running wheel set 300 of the sample wheel transport device 10 can travel directly on flat ground without traveling along the track 30 under the drive of the transport power unit 200.

[0049] Among them, Figure 2As shown, the track 30 can be located outside the driving track 40. The driving track 40 is used for the sample wheel 20 to travel, and the driving track 40 is provided with a storage station A and a verification station B along the length direction. Figure 2 When the wheel is inspected, the upper computer first sends a driving instruction to the clamping power member 400. The clamping power member 400 drives the clamping assembly 500 to clamp the sample wheel 20 at the storage station A (e.g., the end of the garage track) based on the driving instruction. After that, the transporting power member 200 feeds back the clamping operation result of the clamping assembly 500 on the sample wheel 20 to the upper computer. Once the upper computer determines that the clamping assembly 500 has clamped the sample wheel 20, it sends a first transport instruction to the transporting power member 200. The transporting power member 200 drives the walking wheel group 300 to travel along the track 30 based on the first transport instruction until the sample wheel 20 is transported to the inspection station B (e.g., under the track bridge). After the sample wheel 20 completes two rounds of inspection (i.e., before and after the start and end of the locomotive wheel inspection operation), the sample wheel transporting device 10 repeats the above steps to transport the sample wheel 20 from the inspection station B to the storage station A for storage. The host computer may be a host computer of a locomotive wheel flaw detection system, or a host computer of a locomotive transportation system.

[0050] It can be seen that the above-mentioned sample wheel transfer device 10 can replace manual labor to transfer the sample wheel 20 between the storage station A and the verification station B, which can solve the problem that the existing sample wheel 20 is difficult to transfer and requires manual operation, so that the entire transfer operation process of the sample wheel 20 can be automated and professional, thereby improving safety and reliability.

[0051] See also Figure 2 , a standby station C may be provided on the track 30. When the sample wheel 20 performs two rounds of verification at the inspection station B, the sample wheel transfer device 10 may stop at the standby station C and wait for instructions; when the sample wheel 20 completes two rounds of verification, the sample wheel transfer device 10 moves to the inspection station B, transfers the sample wheel 20 to the storage station A, and then returns to the standby station C. Figure 2 , the standby station C may be located between the storage station A and the inspection station B. In some other embodiments, the standby station C may also be located on a side relatively close to the inspection station B, or on a side relatively close to the storage station A.

[0052] Among them, the process of moving the sample wheel transfer device 10 from the verification station B to the standby station C can be described as: when the sample wheel 20 is transferred to the verification station B, the upper computer sends a docking instruction to the transfer power component 200, and the transfer power component 200 stops driving the walking wheel group 300 to move according to the docking instruction, so that the sample wheel transfer device 10 stops moving; thereafter, the upper computer sends a clamping and retracting instruction generated by the docking result of the sample wheel transfer device 10 to the clamping power component 400, and the clamping power component 400 drives the clamping power component 400 to release the sample wheel 20 according to the clamping and retracting instruction; the upper computer sends a third transport instruction generated by the release operation result fed back by the clamping power component 400 to the transfer power component 200, and the transfer power component 200 drives the walking wheel group 300 to move to the standby station C according to the third transport instruction.

[0053] As to how the sample wheel transfer device 10 can dock at the storage station A, the verification station B and the standby station C, an example is given below. The storage station A, the verification station B and the standby station C can all be provided with station information tags. The sample wheel transfer device 10 may also include an acquisition module provided on the side of the transfer platform 100 away from the track 30, and the acquisition module is used to acquire and send the content of the station information tag to the upper computer; the upper computer determines the position reached by the sample wheel transfer device 10 according to the content of the station information tag, and then controls the transfer power part 200 whether to stop driving the walking wheel group 300 to walk based on the determination result.

[0054] In this embodiment, the transport power part 200 may include a reduction motor, and a brake is arranged on the reduction motor. The output shaft of the reduction motor is connected to the walking wheel set 300.

[0055] In this embodiment, the traveling wheel group 300 includes a driving wheel and a driven wheel which are both rotatable, the driving wheel and the driven wheel are arranged at intervals along the movement direction of the transfer platform 100, and the driving wheel is movably connected to the output shaft of the reduction motor.

[0056] Example 2

[0057] See also Figure 3, this embodiment 2 provides a sample wheel transport device 10. Compared with the sample wheel transport device 10 provided in embodiment 1, the clamping assembly 500 of this embodiment may specifically include a clamping platform 510 and two clamping members 520. The clamping platform 510 is arranged at one end of the transport platform 100 relatively close to the sample wheel 20, and the two clamping members 520 are respectively arranged at both ends of the clamping platform 510 along the transport direction of the sample wheel 20; the output shaft of the clamping power member 400 is movably connected to the clamping platform 510. When the clamping power member 400 receives the driving instruction, it drives the clamping platform 510 to move to the specified position, so that the clamping member 520 clamps the sample wheel 20. The two clamping members 520 of the clamping assembly 500 can cooperate to clamp the sample wheel 20, so that when the walking wheel group 300 walks along the track 30, the two clamping members 520 can effectively push the sample wheel 20 to walk along the driving track 40.

[0058] It should be noted that the spacing between the two clamping members 520 along the transport direction of the sample wheel 20 is constant and equal to or slightly greater than the axial length of the sample wheel 20. When the clamping platform 510 moves to the specified position, the two clamping members 520 also reach the axial sides of the sample wheel 20, thereby achieving the clamping operation of the sample wheel 20.

[0059] When the sample wheel 20 is transported to the target position (for example, storage station A or inspection station B), the host computer can send a clamping and retracting instruction to the clamping power member 400. Based on the received clamping and retracting instruction, the clamping power member 400 drives the clamping platform 510 to move a preset distance in the direction away from the sample wheel 20, so that the clamping member 520 is detached from the sample wheel 20, thereby realizing the release operation of the sample wheel 20.

[0060] In this embodiment, a sensor may be provided on the side of the clamping platform 510 relatively close to the sample wheel 20. When the clamping platform 510 moves to a specified position toward the sample wheel 20, the sensor will send a signal to the upper computer, and the upper computer will send a clamping platform 510 in-position instruction to the clamping power member 400 according to the signal, and the clamping power member 400 will stop driving the clamping platform 510 to move based on the clamping platform 510 in-position instruction; similarly, when the clamping platform 510 moves a preset distance away from the sample wheel 20, the sensor will also send a signal to the upper computer, and the upper computer will send a clamping platform 510 in-position instruction to the clamping power member 400 according to the signal, and the clamping power member 400 will stop driving the clamping platform 510 to move based on the clamping platform 510 in-position instruction. The sensor may be a distance sensor.

[0061] See also Figure 3In this embodiment, the ends of the two clamping members 520 away from each other are both provided with rotatable rollers 521, and the curved surface of the rollers 521 contacts the curved surface of the sample wheel 20. It can be understood that the rotation axis of the rollers 521 is parallel to the rotation axis of the sample wheel 20. The rollers 521 can drive the sample wheel 20 to roll along the target track 30 during the movement of the sample wheel transport device 10, so as to facilitate the transportation of the sample wheel 20. It should be noted that the rollers 521 protrude from the clamping platform 510 to ensure that when the clamping platform 510 moves to the command position, the curved surface of the rollers 521 can fully contact the curved surface of the sample wheel 20.

[0062] The roller 521 may include a rotating shaft (not shown in the drawings) disposed on the clamping member 520 and a roller (not shown in the drawings) sleeved on the rotating shaft via a bearing.

[0063] The embodiment does not impose any specific limitation on the diameter of the roller 521, that is, the outer diameter of the cylinder of the roller 521, as long as it can effectively drive the sample wheel 20 to roll. For example, the outer diameter of the roller 521 may be 90 cm.

[0064] In this embodiment, the clamping power member 400 may be a hydraulic cylinder, a pneumatic cylinder or Figure 3 Lead screw motor shown.

[0065] See also Figure 3 In this embodiment, two second slide rails 110 are arranged at intervals along the transport direction of the sample wheel 20 on the side of the transport platform 100 away from the track 30. The two second slide rails 110 are located on both sides of the clamping power member 400, and the second slide rails 110 extend along the moving direction of the clamping platform 510; two second sliders 511 are arranged on the side of the clamping platform 510 relatively close to the transport platform 100. The two second sliders 511 are respectively distributed at both ends of the clamping platform 510 along the transport direction of the sample wheel 20, and the second sliders 511 are slidably arranged on the corresponding second slide rails 110. Through the cooperation of the second slide rails 110 and the second sliders 511, the clamping platform 510 can be moved along a preset route under the drive of the clamping power member 400.

[0066] The second slide rail 110 can be set on the transfer platform 100 by means of snaps, screws, welding, etc., and the second slider 511 can be set on the clamping platform 510 by means of snaps, screws, welding, etc.

[0067] The second sliding block 511 may be provided with a guide groove, wherein the contour of the guide groove matches the cross-sectional contour of the second slide rail 110, for example, both are square or Figure 3 In some other embodiments, the second slide rail 110 may be provided with a guide groove, wherein the contour of the guide groove is adapted to the cross-sectional contour of the second sliding block 511 .

[0068] Example 3

[0069] See also Figure 4 , this embodiment provides a sample wheel transfer device 10. Compared with the sample wheel transfer device 10 provided in Example 2, the structure of the clamping assembly 500 of this embodiment is different from that of the clamping assembly 500 of Example 2. The clamping assembly 500 of this embodiment includes: a clamping platform 510, a position adjustment power member 530 and two clamping members 520. The clamping platform 510 is arranged at one end of the transfer platform 100 relatively close to the sample wheel 20, and the position adjustment power member 530 is arranged on the clamping platform 510 and in the middle of the side away from the track 30; the output shaft of the clamping member 520 is movably connected to the clamping platform 510. Then, when the clamping power member 400 receives the driving instruction, it drives the clamping platform 510 to move to the specified position; the two output ends of the positioning power member 530 along the transport direction of the sample wheel 20 are respectively movably connected with the two clamping members 520, and when the positioning power member 530 receives the positioning instruction generated based on the result of the clamping platform 510 moving into position fed back by the clamping power member 400, it drives the two clamping members 520 to move in opposite directions to each other until the distance between the two clamping members 520 reaches the preset distance, so as to realize the clamping operation of the sample wheel 20. By adjusting the distance between the two clamping members 520 along the transport direction of the sample wheel 20 by the positioning power member 530, the sample wheels 20 of various types of locomotives can be clamped, thereby ensuring that the sample wheel 20 can move together with the sample wheel transport device 10.

[0070] It should be noted that the driving action of the clamping assembly 500 on the sample wheel 20 under the driving instruction includes the pushing operation of the clamping power member 400 on the clamping platform 510 and the adjustment action of the adjustment power member 530 on the clamping force.

[0071] See also Figure 4 The positioning power member 530 can be a dual-output motor with two output ends, and the two output ends are coaxially connected to a lead screw; two first slide rails 511 are arranged on the side of the clamping platform 510 away from the transfer platform 100, and the two first slide rails 511 are respectively distributed at the two ends of the clamping platform 510 along the transfer direction of the sample wheel 20, and each first slide rail 511 extends along the moving direction of the clamping member 520; the clamping member 520 includes a first slider 523 matched with the corresponding lead screw and a clamping arm 522 arranged on the first slider 523, and the first slider 523 is slidably arranged on the corresponding first slide rail 511. The two clamping members 520 share one positioning power member 530, which can simplify the structure of the sample wheel transfer device 10; in addition, through the cooperation of the first slide rail 511 and the first slider 523, the two clamping members 520 can move along a preset route under the cooperation of the positioning power member 530.

[0072] It should be noted that, after the clamping member 520 completes the clamping operation on the sample wheel 20 , the position adjusting power member 530 may experience a clamping force overload. At this time, the position adjusting power member 530 will automatically stop and feed back the clamping operation result to the upper computer.

[0073] The cooperation method between the first slider 523 and the first slide rail 511 can be the same as the cooperation method between the second slider and the second slide rail 110 , and the installation method of the first slide rail 511 on the clamping platform 510 can be the same as the installation method of the second slide rail 110 on the transfer platform 100 .

[0074] See also Figure 4 In this embodiment, two support seats 512 are provided on one side of the clamping platform 510 away from the transfer platform 100, and each support seat 512 is used to support a corresponding lead screw to ensure stable operation of the sample wheel transfer device 10. The support seat 512 may be a "U"-shaped bracket.

[0075] Example 4

[0076] See also Figure 5 , this embodiment provides a sample wheel transfer device 10. Compared with the sample wheel transfer device 10 provided in Example 3, the sample wheel transfer device 10 of this embodiment further includes at least one balancing component 600, which is arranged on the side of the transfer platform 100 facing the track 30, and the balancing component 600 includes a first balancing member 610 and a second balancing member 620 which are arranged at intervals, and the first balancing member 610 and the second balancing member 620 are arranged opposite to each other on both sides of the track 30. The track 30 can be clamped by the cooperation of the first balancing member 610 and the second balancing member 620, so that the sample wheel transfer device 10 maintains balance during the movement, so that the sample wheel transfer device 10 can move smoothly along the track 30.

[0077] The number of the balancing components 600 is not limited in the present embodiment, as long as the motion trajectory of the walking wheel set 300 can be effectively limited in the target direction. Figure 5 The transfer platform 100 shown is provided with two balancing assemblies 600 along the moving direction.

[0078] See also Figure 5 A rotatable balancing wheel 630 is provided at one end of the first balancing member 610 and / or the second balancing member 620 away from the transfer platform 100. The balancing wheel 630 can move along the upper wall and / or the lower wall of the track 30. The balancing wheel 630 can prevent the balancing assembly 600 from dry grinding with the track 30, thereby reducing the movement resistance of the sample wheel transfer device 10.

[0080] See also Figure 1 and Figure 6 This embodiment provides a sample wheel transport device 10. Compared with the sample wheel transport device 10 provided in Example 4, the sample wheel transport device 10 further includes at least two sample wheel limiting mechanisms 700, which are arranged on the other side of the track 30 opposite to the running wheel group 300; when the sample wheel limiting mechanism 700 receives the sample wheel 20 in place instruction, the sample wheel 20 stops moving; when the sample wheel limiting mechanism 700 receives the limit retraction instruction, the sample wheel 20 is released.

[0081] The sample wheel limiting mechanism 700 can be set on the ground adjacent to the storage station A, and on the ground adjacent to the verification station B. When the sample wheel 20 is parked at the storage station A or the verification station B, the sample wheel limiting mechanism 700 can limit the sample wheel 20 according to the received sample wheel 20 arrival instruction, which can prevent the sample wheel 20 from moving along the track 30, and ensure the normal storage or verification of the sample wheel 20; if the sample wheel 20 leaves the storage station A or the verification station B, the sample wheel limiting mechanism 700 can release the sample wheel 20 according to the received limit retraction instruction, which can ensure that the walking wheel group 300 can drive the sample wheel 20 to move to the target position under the drive of the transport power part 200. Among them, the sample wheel 20 arrival instruction and the limit retraction instruction can both be generated and issued by the host computer.

[0082] The number of the sample wheel limiting mechanisms 700 is not specifically limited in this embodiment, as long as the sample wheel 20 can be stored normally or the calibration operation can be performed normally without slipping. Figure 1 The sample wheel transport device 10 shown includes two sample wheel limiting mechanisms 700 , one of which is installed at the storage station A, and the other is installed at the calibration station.

[0083] Example 6

[0084] See also Figure 7, this embodiment provides a sample wheel transport device 10. Compared with the sample wheel transport device 10 provided in Example 6, the sample wheel limiting mechanism 700 of this embodiment may specifically include a stop power member 710 and a stop wheel member 720; the stop power member 710 drives the stop wheel member 720 to release the sample wheel 20 according to the limit retraction instruction generated based on the clamping operation result fed back by the clamping power member 400; the transport power member 200 also drives the walking wheel group 300 to transport the sample wheel 20 to the target position according to the second transport instruction generated based on the release operation result fed back by the stop wheel member 720; the stop power member 710 also drives the stop power member 710 to limit the sample wheel 20 according to the sample wheel 20 arrival instruction generated based on the docking result fed back by the transport power member 200; the clamping power member 400 also drives the clamping power member 400 to release the sample wheel 20 according to the clamping retraction instruction generated based on the limit operation result. By limiting the sequence of actions of the various components of the sample wheel transport device 10 in this way, the normal progress of the entire transport process of the sample wheel 20 can be ensured.

[0085] Among them, the stop power member 710, the clamping power member 400 and the transfer power member 200 can interact with each other through the host computer, and the interaction process can be described as follows:

[0086] At the storage station A, after the clamping assembly 500 completes the clamping operation on the sample wheel 20, the clamping power component 400 feeds back the clamping operation result of the sample wheel 20 to the upper computer, and the upper component generates and sends a limit retraction instruction to the stop power component 710 based on the clamping operation result; the stop power component 710 drives the stop wheel component 720 to release the sample wheel 20 based on the limit retraction instruction, and feeds back the release operation result of the sample wheel 20 to the upper computer, and the upper computer generates and sends a second transport instruction to the transfer power component 200 based on the release operation result; the transfer power component 200 drives the walking wheel group 300 to drive the sample wheel 20 to be transported to the verification station B based on the second transport instruction.

[0087] When the sample wheel 20 moves to the inspection station B, the host computer sends a docking instruction to the transfer power component 200. The transfer power component 200 stops driving the walking wheel group 300 to move according to the received docking instruction, and then feeds back the docking result to the host computer; the host computer generates a sample wheel 20 arrival instruction according to the docking result and sends it to the stop power component 710. The stop power component 710 drives the stop wheel component 720 to limit the sample wheel 20, and then feeds back the result of the limit operation on the sample wheel 20 to the host computer; based on the limit operation result, the host computer generates and sends a clamping retraction instruction to the clamping power component 400. The clamping power component 400 drives the clamping power component 400 to release the sample wheel 20 based on the clamping retraction instruction.

[0088] In this embodiment, a position switch (not shown in the drawings) may be provided on the wheel stopper 720, and when the wheel stopper 720 realizes the limiting operation or the releasing operation on the sample wheel 20, the position switch will send a signal to the upper computer. The position switch may be a photoelectric switch or a mechanical switch.

[0089] In this embodiment, see Figure 7 The sample wheel limiting mechanism 700 may further include a base 730, which may be installed on the ground to fix the sample wheel limiting mechanism 700; wherein the stopping power member 710 and the wheel stopping member 720 are both arranged on a side of the base 730 facing away from the ground.

[0090] In this embodiment, see Figure 7 The above-mentioned stop power member 710 can be a screw motor; the sample wheel limiting mechanism 700 also includes a stop platform 740, which is movably connected to the output shaft of the stop power member 710, and the wheel stop member 720 includes a first wheel stop block 721 and a second wheel stop block 722, which are arranged on the stop platform 740 at intervals along the moving direction of the walking wheel group 300. The cooperation between the stop platform 740 and the screw motor can simultaneously drive the first wheel stop block 721 and the second wheel stop block 722 to move.

[0091] The stop power member 710 may be conductively connected to an external power source. Of course, a power supply unit for supplying power to the stop power member 710 may also be provided on the base 730 of the sample wheel limiting mechanism 700 .

[0092] See also Figure 7 , the height of the first wheel stop 721 gradually increases in the direction away from the second wheel stop 722; and / or, the height of the second wheel stop 722 gradually increases in the direction away from the first wheel stop 721. By setting the sizes of the first wheel stop 721 and the second wheel stop 722 in this way, the screw motor can push the first wheel stop 721 and the second wheel stop 722 to the bottom of the sample wheel 20, so that the sample wheel 20 can be effectively limited.

[0093] See also Figure 7 Two third slide rails 731 are arranged on one side of the base 730 close to the stop platform 740. The two third slide rails 731 are distributed in the middle of the base 730 and located on both sides of the stop power member 710. The third slide rails 731 extend along the moving direction of the wheel stop member 720. Two third sliders 741 are arranged on one side of the stop platform 740 close to the base 730. The two third sliders 741 are distributed at both ends of the stop platform 740. The third sliders 741 are slidably arranged on the corresponding third slide rails 731. Through the cooperation between the third sliders 741 and the third slide rails 731, the wheel stop member 720 can move along a preset route under the drive of the positioning power member.

[0094] The cooperation method between the third slider 741 and the third slide rail 731 is the same as the cooperation method between the second slider and the second slide rail 110. The installation method of the third slide rail 731 on the base 730 can be the same as the installation method of the second slide rail 110 on the transfer platform 100. The installation method of the third slider 741 on the stop platform 740 can be the same as the installation method of the second slider on the clamping platform 510.

[0095] In this embodiment, the sample wheel limiting mechanism 700 may further include a housing, which is used to cover the base 730, the third power member, and the stop platform 740, and the wheel stop member 720 may extend to the outside of the housing or retract into the housing. The housing may protect the internal components of the sample wheel limiting mechanism 700200.
