[0031] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0032] The present invention provides a high-position detection device for a grinding structure for rail grinding. The grinding structure is driven by a driving cylinder to move up and down. The device includes:

[0033] A first induction plate, arranged on the grinding structure;

[0034] A position detection structure, arranged on the cylinder seat of the driving cylinder. The position detection structure includes a detection switch, and when the grinding structure is at a high position point, the detection switch can detect the first induction plate and send out an induction signal;

[0035] A control unit, connected to the detection switch and the driving cylinder, for receiving the induction signal and displaying it on a display screen.

[0036] Specifically, the detection device includes a first induction plate and a position detection structure. The first induction plate can move up and down synchronously with the grinding structure. The position detection structure accurately determines the height position of the grinding structure by detecting the position of the first induction plate through a detection switch. During the grinding process, the grinding structure moves up and down in the vertical direction of the rail to perform the grinding operation on the rail. When the grinding structure rises to the highest position and stops, it indicates that the grinding structure is at the "high position" and stops working. At this time, the first induction plate can trigger the detection switch, and the triggered signal is fed back to the control unit and displayed on the display screen.

[0037] In one embodiment, the detection switch is a non-contact proximity switch, which has no mechanical rotating parts compared with a travel switch, avoiding signal errors caused by jamming of rotating parts.

[0038] Optionally, the position detection structure includes a base, which includes a first connection surface and a second connection surface. One end of the first connection surface is perpendicularly connected to the second connection surface. The cylinder block of the driving cylinder is connected to the first connection surface, and the second connection surface is connected to the detection switch.

[0039] Specifically, in the position detection structure, the detection switch is connected and fixed through the base, and the cylinder block of the driving cylinder is connected by a screw connection method, which is convenient for maintenance and wiring. Since the installation surface of the cylinder block of the driving cylinder is set in the vertical direction, and the detection switch detects the first induction plate also moving along the vertical direction, the first connection surface connecting the cylinder block and the second connection surface connecting the detection switch need to be perpendicular to each other. The base adopts a 90° bending structure, which can ensure that the wire outlet of the detection switch is located above the detection device after installation. Considering strength and force analysis, an angle steel is used for processing to make the base.

[0040] Optionally, the grinding structure includes:

[0041] A movable arm, one end of which is connected to the first induction plate, and the other end of the movable arm is hingedly connected to the cradle frame. The output end of the driving cylinder is connected to the movable arm and drives the movable arm to move up and down;

[0042] A grinding motor, which is connected to one end of the movable arm.

[0043] Specifically, the grinding structure drives the grinding motor using the lever principle. When the output end of the driving cylinder extends upward in the vertical direction, the movable arm drives the grinding motor to descend, and the grinding motor performs the grinding operation on the rail. When the output end of the driving cylinder retracts downward in the vertical direction, the movable arm drives the grinding motor to rise, and the grinding motor leaves the rail. The first induction plate is also arranged at one end of the movable arm corresponding to the grinding motor. When the grinding motor rises to the "high position", the first induction plate can rise into the detection range of the detection switch, trigger the detection switch, and the detection device can accurately detect that the grinding motor reaches the set position.

[0044] Optionally, the movable arm is U-shaped and is arranged horizontally in the cradle frame. The opening of the movable arm faces the driving cylinder. The first induction plate is connected to both ends of the movable arm, and the grinding motor is connected to the inner side of the movable arm.

[0045] Specifically, one movable arm is arranged on each side of the driving cylinder, and the opening directions of the movable arms both face the driving cylinder. In this way, the detection switch connected to the driving cylinder can more easily detect the vertical position of the grinding motor. The grinding motor is connected to the inner ring of the movable arm. The hinge points of the movable arm are respectively arranged at the end positions close to both ends of the U shape, and a first induction plate is arranged between the two U-shaped ends. When the grinding motor rises away from the rail towards the "high position", the movable arm will drive the first induction plate to move downward. When the first induction plate reaches the detection range of the detection switch, it indicates that the grinding motor has reached the "high position", and the display screen shows the motor high position.

[0046] Optionally, the first induction plate includes an induction part and two connecting parts. The induction part is U-shaped, and the connecting parts are respectively vertically connected to both ends of the induction part. The connecting parts are bolted to one end of the movable arm, and an avoidance groove is formed on the side of the induction part close to the driving cylinder.

[0047] Specifically, to avoid the position of the induction switch affecting the space occupied by the cradle frame in the height direction, the detection switch is preferably arranged at a position below the cylinder seat of the driving cylinder. Since the connecting end of the movable arm and the first induction plate will not drop too much when the grinding motor reaches the "high position", the induction part of the first induction plate is set to be U-shaped, and the induction part can more easily trigger the induction switch. To ensure that the induction part will not rub against the driving cylinder during the up and down movement, an avoidance groove is provided.

[0048] Optionally, the second connecting surface is connected to the detection switch through a movable plate. The second connecting surface is provided with a long oval hole, and the long oval hole is arranged along the length direction of the first induction plate.

[0049] Specifically, a movable plate can also be arranged between the base and the detection switch. The long oval hole on the movable plate can enable the detection switch to be adjusted horizontally to meet the installation requirements of each component.

[0050] Optionally, it further includes a travel switch. The travel switch is arranged on the cradle frame, and a second induction plate is connected to the movable arm. The second induction plate cooperates with the travel switch.

[0051] Specifically, a second induction plate is arranged on the movable arm in the vertical direction. The second induction plate moves synchronously with the up-and-down movement of the grinding motor. A travel switch is fixedly arranged near the driving cylinder of the cradle frame. In this way, when the grinding motor rises to the "high position", the second induction plate can contact the travel switch, further ensuring the accurate detection of the position of the grinding motor by the detection device and guaranteeing the quality of the grinding operation and the safety of the traveling crane.

[0052] The present invention also provides a rail vehicle, including the above-mentioned high-position detection device for the grinding structure of the rail grinding.

[0053] Embodiment

[0054] As Figures 1 to 8 shown, the present invention provides a high-position detection device for the grinding structure of the rail grinding. The grinding structure is driven by a driving cylinder 2 to move up and down. The device includes:

[0055] A first induction plate 1, arranged on the grinding structure;

[0056] A position detection structure, arranged on the cylinder block of the driving cylinder 2. The position detection structure includes a detection switch 3. When the grinding structure is at the high position point, the detection switch 3 can detect the first induction plate 1 and send out an induction signal;

[0057] A control unit, connected to the detection switch 3, for receiving the induction signal and displaying it on the display screen.

[0058] In this embodiment, the position detection structure includes a base 4. The base 4 includes a first connection surface 5 and a second connection surface 6. One end of the first connection surface 5 is vertically connected to the second connection surface 6. The cylinder block of the driving cylinder 2 is connected to the first connection surface 5, and the second connection surface 6 is connected to the detection switch 3.

[0059] In this embodiment, the grinding structure includes:

[0060] A movable arm 7, one end of which is connected to the first induction plate 1. The other end of the movable arm 7 is hinged to the cradle frame 8. The output end of the driving cylinder 2 is connected to the movable arm 7 and drives the movable arm 7 to move up and down;

[0061] A grinding motor 9, connected to one end of the movable arm 7.

[0062] In this embodiment, there are two grinding motors 9, and the grinding motors 9 are respectively arranged on both sides of the driving cylinder 2.

[0063] In this embodiment, the movable arm 7 is U-shaped. The movable arm 7 is arranged horizontally in the cradle frame 8. The opening of the movable arm 7 faces the driving cylinder 2. The first induction plate 1 is connected to both ends of the movable arm 7, and the grinding motor 9 is connected to the inner side of the movable arm 7.

[0064] In this embodiment, the first induction plate 1 includes an induction portion 10 and two connecting portions 11. The induction portion 10 is U-shaped, and the connecting portions 11 are perpendicularly connected to both ends of the induction portion 10 respectively. The connecting portions 11 are bolted to one end of the movable arm 7. An avoidance groove 12 is formed on the side of the induction portion 10 close to the driving cylinder 2.

[0065] In this embodiment, the second connecting surface 6 is connected to the detection switch 3 through the movable plate 13. A long oval hole 14 is formed on the second connecting surface 6, and the long oval hole 14 is arranged along the length direction of the first induction plate 1.

[0066] In this embodiment, a travel switch is further included. The travel switch is arranged on the cradle frame 8, and a second induction plate is connected to the movable arm 7. The second induction plate cooperates with the travel switch.

[0067] The present invention also provides a rail vehicle, including the above-mentioned high-position detection device for the grinding structure used for rail grinding.

[0068] In summary, the detection device drives the grinding motor 9 to move up and down through the driving cylinder 2. When the grinding motor 9 needs to leave the rail and stop grinding, when the output end of the driving cylinder 2 retracts downward, the connection end of the movable arm 7 and the grinding motor 9 is lifted upward. When the grinding motor 9 reaches the "high position", the connection end of the movable arm 7 and the first induction plate 1 enters the induction area of the detection switch 3. In this way, the detection switch 3 sends out a signal and transmits it to the driving cylinder 2 to make it stop working. In this way, the grinding operation can be well controlled and the driving safety can be improved.

[0069] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
