Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1, 3 and 5, the wheelset turntable according to an embodiment of the present invention includes a turntable body 20, a throwing mechanism 30 and an orientation detecting mechanism 40. The turntable body 20 includes a disk surface 21, and the turntable body 20 is rotatable about a direction perpendicular to the disk surface 21. The disc face 21 is provided with a guide groove 211 for fitting with the wheel pair, the guide groove 211 having opposite first and second end notches 2111 and 2112. The throwing mechanism 30 is provided corresponding to the guide groove 211, and the throwing mechanism 30 can throw the wheel pair toward the first end notch 2111 and the second end notch 2112, respectively. The orientation detecting mechanism 40 is used to detect the orientation of the guide groove 211 during the rotation of the turntable body 20; wherein when the orientation detection mechanism 40 detects that the first end notch 2111 or the second end notch 2112 is in the same orientation as the rail 60, the throwing mechanism 30 is controlled to throw the pair of wheels corresponding to the first end notch 2111 or the second end notch 2112.

In the present embodiment, the fact that the throwing mechanism 30 is disposed corresponding to the guide groove 211 means that the throwing mechanism 30 is located in or below the guide groove 211 during the rotation of the turntable body 20. After rotating into position, portions of the throwing mechanism 30 can lift from the guide slots 211 and exert a force on the wheels of the wheel set. Of course, in other embodiments, the throwing mechanism 30 may be set according to actual requirements, as long as the throwing effect can be achieved.

During operation, the wheel pair turntable pushes wheels of a wheel pair into the guide groove 211 and positions the wheels. Then, the turntable body 20 is rotated in a direction perpendicular to the disk surface 21, while the orientation detection mechanism 40 detects the orientation of the guide groove 211. Specifically, during the rotation of the turntable body 20, if the orientation detection mechanism 40 detects that the first end notch 2111 and the second end notch 2112 of the guide slot 211 are not located at the same orientation as the track 60, i.e., the first end notch 2111 and the second end notch 2112 are not aligned with the track 60, the throwing mechanism 30 does not operate; if the orientation detection mechanism 40 detects that the first end notch 2111 of the guide groove 211 is located at the same orientation as the track 60, i.e., the first end notch 2111 is aligned with the track 60, the throwing mechanism 30 is controlled to throw the wheel pair toward the first end notch 2111; if the orientation detecting mechanism 40 detects that the second end notch 2112 of the guide groove 211 is in the same orientation as the rail 60, i.e., the second end notch 2112 is aligned with the rail 60, the throwing mechanism 30 is controlled to throw the pair of wheels toward the second end notch 2112. Thus, in the rotating process of the turntable body 20, the position detection mechanism 40 detects the position of the guide slot 211 in real time, and determines whether the first end notch 2111 of the guide slot 211 and the rail 60 are located at the same position or the second end notch 2112 and the rail 60 are located at the same position, so that the throwing mechanism 30 is controlled to correspondingly throw the wheel pair to the first end notch 2111 or the second end notch 2112, the position does not need to be determined manually, safety accidents caused by position misjudgment are avoided, and the position determination accuracy and reliability are high.

In one embodiment, referring to fig. 1 and 3, the wheelset turntable further comprises a frame 10, and the turntable body 20 is movably mounted to the frame 10. The orientation detection mechanism 40 includes a detection member 41 and an engagement member 42 engaged with the detection member 41, and at least two detection members 41 and at least two engagement members 42 are provided. At least two detecting members 41 are disposed on the frame 10 at a predetermined angle therebetween, and at least two mating members 42 are disposed on the turntable body 20 at a predetermined angle therebetween. Wherein, the rotation center of the turntable body 20 is used as the center of a circle, and the included angle between the center of a circle and the connecting line of two adjacent mating members 42 is the preset angle.

In the present embodiment, two detection members 41 and two fitting members 42 are provided. For convenience of description, the two detecting members 41 and the two fitting members 42 are named as a No. 1 detecting member 411, a No. 2 detecting member 412, a No. 1 fitting member 421, and a No. 2 fitting member 422, respectively. In operation, the turntable body 20 rotates in a direction perpendicular to the disk surface 21, and the mating member 42 rotates with the turntable body 20. For example, referring to fig. 5, when the turntable body 20 rotates clockwise in the direction perpendicular to the disk surface 21, and the No. 1 detecting element 411 and the No. 1 mating element 421 detect the mating, and the No. 2 detecting element 412 and the No. 2 mating element 422 detect the mating, both the No. 1 detecting element 411 and the No. 2 detecting element 412 have detecting signals, and output a signal "11", at this time, neither the first end notch 2111 nor the second end notch 2112 of the guide slot 211 is aligned with the track 60, and the sending mechanism 30 does not operate. Referring to fig. 6, the turntable body 20 rotates clockwise, when only the No. 2 detecting element 412 is matched with the No. 1 matching element 421 for detection, the No. 2 detecting element 412 has a detection signal, and outputs a signal "01", and the second end notch 2112 of the guide groove 211 is aligned with the track 60, so that the throwing mechanism 30 is controlled to throw the wheel pair towards the second end notch 2112. Referring to fig. 7, when the turntable body 20 rotates clockwise, neither the detecting element 411 nor the detecting element 412 of No. 1 has a detecting signal, and outputs a signal "00", at this time, both the first end notch 2111 and the second end notch 2112 of the guide slot 211 are not aligned with the track 60, and the throwing mechanism 30 does not operate. Referring to fig. 8, the turntable body 20 rotates clockwise, when the detecting element 411 No. 1 and the engaging element 422 No. 2 perform the engagement detection, the detecting element 411 No. 1 has a detection signal "10", and the first end notch 2111 of the guiding slot 211 is aligned with the track 60, so as to control the throwing mechanism 30 to throw the wheel pair toward the first end notch 2111. In this way, during the rotation of the turntable body 20, the orientation of the guide groove 211 can be detected through the matching between the detection piece 41 and the matching piece 42, and it is determined whether the first end notch 2111 of the guide groove 211 is aligned with the rail 60 or the second end notch 2112 is aligned with the rail 60, so that the throwing mechanism 30 is correspondingly controlled to throw the wheel pair to the first end notch 2111 or the second end notch 2112, the orientation does not need to be determined manually, and the safety accident caused by the misjudgment of the orientation is avoided.

It should be noted that, three or more wheel-set rotating discs with detecting elements 41 and mating elements 42 are provided, and the method for determining the orientation of the guiding groove 211 can refer to the above logic, and will not be described herein.

Further, referring to fig. 3 and 5, two detecting members 41 are provided, and the two detecting members 41 are disposed at 90 ° between the racks 10. Two fitting pieces 42 are arranged, and the two fitting pieces 42 are correspondingly arranged on the turntable body 20 at an angle of 90 degrees. Specifically, with the rotation center of the turntable body 20 as the center of a circle, any first straight line passing through the center of a circle is selected, and then a second straight line passing through the center of a circle and perpendicular to the first straight line is selected; the two matching pieces 42 are respectively positioned on a first straight line and a second straight line and are arranged on the turntable body 20; the two detecting members 41 correspond to the two mating members 42 one by one, and are mounted on the frame 10. In this way, by the engagement of the two detection pieces 41 and the two engagement pieces 42, the guide groove 211 can be positioned in four directions, i.e., front-rear and left-right, and the control logic is simple.

Alternatively, the detecting element 41 is a proximity switch, and the engaging element 42 is a sensing element capable of inductively engaging with the proximity switch, for example, the sensing element is a metal sensing piece. Of course, in other embodiments, the detecting member 41 may also be a transmitter, such as a laser transmitter; the engagement member 42 is a receiver capable of engagement by a transmitter, for example the receiver may be a laser receiver.

In one embodiment, referring to fig. 1, 9 and 10, the throwing mechanism 30 includes a first throwing block 32 and a second throwing block 35, the first throwing block 32 being rotatably coupled to the turntable body 20 by a first rotating shaft 31, the second throwing block 35 being rotatably coupled to the turntable body 20 by a second rotating shaft 34. The first throwing block 32 and the second throwing block 35 respectively comprise a first throwing part 321 and a second throwing part 351 which can be accommodated in the guide groove 211, and the first throwing block 32 can rotate around the first rotating shaft 31 and is used for enabling the first throwing part 321 to be lifted to abut against the wheel and throw the wheel pair to the first end notch 2111; the second throwing block 35 is rotatable about the second axis of rotation 34 for raising the second throwing portion 351 into abutment with the wheel and throwing the pair of wheels towards the second end notch 2112. During operation, the wheel set is pushed into the guide groove 211 of the turntable body 20, and at this time, the first throwing portion 321 and the second throwing portion 351 are both accommodated in the guide groove 211, and do not apply acting force to the wheel. Then, the turntable body 20 is rotated in a direction perpendicular to the disk surface 21, while the orientation detection mechanism 40 detects the orientation of the guide groove 211. When the orientation detecting mechanism 40 detects that the first end notch 2111 of the guide groove 211 is aligned with the rail 60, the first throwing portion 321 is lifted from the guide groove 211 to abut against the wheel and exerts a force on the wheel to throw the wheel toward the first end notch 2111, and in this process, the second throwing portion 351 is accommodated in the guide groove 211. When the orientation detection mechanism 40 detects that the second end notch 2112 of the guide groove 211 is aligned with the rail 60, the second throwing portion 351 is lifted from the guide groove 211 to abut against the wheel and exerts a force on the wheel to throw the wheel toward the second end notch 2112, and in this process, the first throwing portion 321 is accommodated in the guide groove 211. In this way, the first throwing portion 321 and the second throwing portion 351 can correspondingly throw the pair of wheels toward the first end notch 2111 and the second end notch 2112 of the groove of the rail 60, and the structure is simple.

Further, the first and second throwing portions 321 and 351 are each mounted with a flexible pad. Optionally, the flexible pad is a rubber pad or the like. Therefore, the flexible pad can play a role in buffering, hard contact between the first throwing block 321 and the second throwing block 351 with the wheel is avoided, abrasion of the wheel is reduced, and the service life of the wheel pair is prolonged.

Further, referring to fig. 1, 9 and 10, the throwing mechanism 30 further includes a first driving member 33 and a second driving member 36, and the first driving member 33 and the second driving member 36 are respectively connected to the position detecting mechanism 40 in communication. Specifically, the wheel-set turntable further comprises a controller, and the controller is respectively connected with the position detection mechanism 40, the first driving element 33 and the second driving element 36 in a communication manner. The first driving member 33 is in driving connection with the first throwing block 32, and is used for driving the first throwing block 32 to rotate around the first rotating shaft 31. The second driving member 36 is in driving connection with the second throwing block 35, and is used for driving the second throwing block 35 to rotate around the second rotating shaft 34. In operation, when the orientation detection mechanism 40 detects that the first end notch 2111 of the guide groove 211 is aligned with the track 60, the first driving element 33 is controlled to operate, so as to drive the first throwing block 32 to rotate around the first rotating shaft 31, so that the first throwing portion 321 is lifted to abut against the wheel of the wheel set, and a force is applied to the wheel, so that the wheel set is thrown towards the first end notch 2111. After the wheel pair is thrown out of the turntable body 20, the first driving member 33 drives the first throwing block 32 to rotate reversely around the first rotating shaft 31, so that the first throwing portion 321 moves downwards and is accommodated in the guide groove 211. Similarly, the working principle of the second driving member 36 is the same as that of the first driving member 33, and is not described herein again. Therefore, the first driving part 33 and the second driving part 36 respectively provide driving force for the first throwing block 32 and the second throwing block 35, and correspondingly drive the first throwing block 32 and the second throwing block 35 to rotate, so that manual operation is not needed, the labor intensity is reduced, and the operation efficiency is improved.

Optionally, the first driving member 33 and the second driving member 36 are both an air cylinder, an electric cylinder, and the like, a cylinder body of the air cylinder, the electric cylinder, and the like is fixed on the turntable body 20, and a power shaft of the air cylinder, the electric cylinder, and the like is in driving connection with the first throwing block 32 and the second throwing block 35.

Further, referring to fig. 1, 9 and 10, the first and second throwing blocks 32 and 35 are respectively disposed along the extending direction of the guide groove 211. One end of the first throwing block 32 close to the second throwing block 35 is rotatably connected with the turntable body 20 through a first rotating shaft 31, and a first throwing part 321 is arranged at the end area of the first throwing block far away from the first rotating shaft 31; the first driving member 33 is disposed corresponding to the first throwing portion 321 and is drivingly connected to the first throwing block 32. One end of the second throwing block 35 close to the first throwing block 32 is rotatably connected with the turntable body 20 through a second rotating shaft 34, and a second throwing part 351 is arranged at the end area of the second throwing block 35 far away from the second rotating shaft 34; the second driving member 36 is disposed corresponding to the second throwing portion 351 and is in driving connection with the second throwing block 35. Thus, in the process that the first throwing block 32 or the second throwing block 35 collides with the wheel, the first driving element 33 and the second driving element 36 can correspondingly provide support for the first throwing portion 321 and the second throwing portion 351, so that the first throwing portion 321 and the second throwing portion 351 are prevented from generating large deformation in the process of throwing the wheel pair, and the first throwing block 32 and the second throwing block 35 can be effectively ensured to throw the wheel pair out of the turntable body 20 towards the first end notch 2111 and the second end notch 2112 respectively.

In this embodiment, the first driving member 33 is drivingly connected to the middle of the first throwing portion 321 in the extending direction of the guide groove 211, and the second driving member 36 is drivingly connected to the middle of the second throwing portion 351 in the extending direction of the guide groove 211.

Of course, in other embodiments, the throwing mechanism 30 includes a throwing block fitted to the guide groove 211, and the middle of the throwing block in the extending direction of the guide groove 211 is provided with a rotating shaft.

In operation, the wheel pair is pushed into the guide groove 211, and is moved along the extending direction of the guide groove 211 until the wheels of the wheel pair are positioned on the positioning groove body 212. Then, the turntable body 20 is rotated in a direction perpendicular to the disk surface 21 until rotated to a specified position. Because the at least two opposite groove walls 2121 of the positioning groove body 212 along the extending direction of the guide groove 211 are provided with the contact parts 2122, the contact parts 2122 are in contact fit with two sides of the bottom of the wheel surface of the wheel, so as to position the wheel pair in the guide groove 211, prevent the wheel pair from being separated from the guide groove 211 in the rotating process of the turntable body 20, and improve the stability of the wheel pair. In addition, in the rotating process of the turntable body 20, the at least two interference parts 2122 limit the movement of the wheel along the extending direction of the guide groove 211, so that the oscillation and swing period of the wheel set in the rotating process of the turntable body 20 is reduced, the positioning time of the wheel set is shortened, and the positioning accuracy can be improved.
