[0003] Common turnout sections include structures such as point rails, guard rails, harmful spaces, and frog heart rails. Different sections of the turnout have a certain height difference. Among them, the harmful space is a space between the frog throat of the wing rail and the actual tip of the frog. It is the gap at the end of the track. In this space, the wheel flange loses the guidance of the rail. When the turnout grinding device is performing grinding operations, the guide wheel of the grinding unit is prone to collide with the frog tip. It is often necessary to lift the grinding device in the harmful space or install a guide plate in the harmful space so that the grinding device can cross the harmful space and then perform grinding operations. However, the lifting method and the guide plate installation method are complicated to operate in actual application, the grinding device has low passing efficiency, and cannot effectively solve the problem of the guide wheel of the grinding unit colliding with the frog tip.

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] Example 1

[0038] like Figures 1 to 7 As shown, the adjustment mechanism for the turnout grinding device of the present invention comprises:

[0039] A guide shaft 4, used to connect with the turnout grinding assembly 1;

[0040] The guide sleeve 2 is sleeved on the guide shaft 4, and the guide shaft 4 can move along its own axis in the guide sleeve 2 to adjust the lateral position of the turnout grinding assembly 1;

[0041] A connecting rod assembly 5, both ends of which are rotatably connected to corresponding guide sleeves 2, and the guide sleeves 2 can rotate around their own axes to adjust the longitudinal position of the turnout grinding assembly 1;

[0042] The hydraulic expansion sleeve 3 is sleeved between the guide shaft 4 and the guide sleeve 2, and can lock or unlock the guide shaft 4 and the guide sleeve 2.

[0043] Specifically, the adjustment mechanism for the turnout grinding device includes a guide shaft 4 , a guide sleeve 2 , a connecting rod assembly 5 and a hydraulic expansion sleeve 3 .

[0044] Among them, the guide shaft 4 is used to connect with the turnout grinding assembly 1, and the connection method between the two is not limited as long as a stable and reliable connection is achieved.

[0045] The guide sleeve 2 is sleeved on the guide shaft 4. The guide shaft 4 can move in the guide sleeve 2 to change the lateral position of the turnout grinding assembly 1. After the lateral position is adjusted in place, it can be locked by the hydraulic expansion sleeve 3. The lateral position of the turnout grinding assembly 1 is the position along the axial direction of the guide shaft 4. The guide shaft 4 can be moved in the guide sleeve 2 by a cylinder or other driving method to adjust the lateral position of the turnout grinding assembly 1. The setting of the guide sleeve 2 provides a guiding effect for the movement of the guide shaft 4.

[0046] Both ends of the connecting rod assembly 5 are rotatably connected to the corresponding guide sleeves 2, and the guide sleeves 2 are provided with guide shafts 4, and the guide shafts 4 are connected to the turnout grinding assembly 1, that is, both ends of the connecting rod assembly 5 are connected to the turnout grinding assembly 1. The guide sleeves 2 can be rotated to adjust the longitudinal position of the turnout grinding assembly 1 at both ends. The rotation of the guide sleeves 2 can be achieved by a separate power part or by the power part of the turnout grinding assembly 1. The longitudinal position refers to Figures 1 to 4 The upper and lower positions in the middle.

[0047] A hydraulic expansion sleeve 3 is arranged between the guide shaft 4 and the guide sleeve 2, and the guide shaft 4 and the guide sleeve 2 can be locked by the hydraulic expansion sleeve 3. When one set of turnout grinding assemblies 1 is locked in the horizontal direction, the other set of turnout grinding assemblies 1 can adjust the horizontal position of this set of turnout grinding assemblies 1 by moving the guide shaft 4 in the guide sleeve 2, that is, the adjustment of the horizontal position of one set of turnout grinding assemblies 1 relative to the horizontal position of the other set of turnout grinding assemblies 1 is not affected. Based on this, the axes of the guide wheels 15 of the turnout grinding assemblies 1 at both ends of the connecting rod assembly 5 can be adjusted to be in the same horizontal plane in the longitudinal direction, and the abutment surface of the guide wheel 15 (the surface in contact with the rail 16) and the extension direction of the rail 16 are in the same vertical plane, and then the turnout grinding assemblies 1 at both ends of the connecting rod assembly 5 are locked by the hydraulic expansion sleeve 3. In this way, when passing through the turnout, it can be ensured that when the turnout grinding assembly 1 at one end enters the harmful space, the turnout grinding assembly 1 at the other end leans against the rail 16, so that the turnout grinding assembly 1 can quickly pass through the harmful space.

[0048] When the hydraulic expansion sleeve 3 releases the lock between the guide shaft 4 and the guide sleeve 2, the lateral position of the turnout grinding assembly 1 can be adjusted by moving the guide shaft 4 in the guide sleeve 2. The guide sleeve 2 rotates around the guide shaft 4, driving the connecting rod assembly 5 to rotate and adjust, so as to adjust the longitudinal position of the turnout grinding assembly 1 to adapt to the grinding operation at different high positions. In this way, the lateral position and longitudinal position of the two groups of turnout grinding assemblies 1 connected by the adjustment mechanism can be adjusted separately or together without affecting each other. When the position of one group of turnout grinding assemblies 1 is locked by the hydraulic expansion sleeve 3, the lateral and longitudinal movement of the other group of turnout grinding assemblies 1 can also be unrestricted.

[0049] It should be noted that the two groups of turnout grinding assemblies 1 mentioned in this embodiment do not limit their quantity, and the adjustment mechanism provided by the present invention can be applied to multiple groups of turnout grinding assemblies 1.

[0050] In a specific application, the turnout grinding assembly 1 is adjusted in lateral position by the guide shaft 4, and the guide sleeve 2 is rotated around the guide shaft 4 to drive the connecting rod assembly 5 to rotate and adjust, so as to adjust the longitudinal position of the turnout grinding assembly 1, and then the guide sleeve 2 and the guide shaft 4 are locked by the hydraulic expansion sleeve 3, that is, the positions of the turnout grinding assemblies 1 at both ends of the connecting rod assembly 5 are locked, so that the turnout grinding assemblies 1 at both ends of the connecting rod assembly 5 become a whole, and ensure that the axes of the guide wheels 15 on the two groups of turnout grinding assemblies 1 are in the same horizontal plane in the longitudinal direction, and the surfaces of the guide wheels 15 and the extending direction of the rails 16 are in the same vertical plane (see Appendix). Figure 7 As shown in the figure, when passing through the turnout, it can be ensured that when one end of the turnout grinding assembly 1 enters the harmful space, the other end of the turnout grinding assembly 1 leans against the rail 16, so that the turnout grinding assembly 1 can quickly pass through the harmful space. This can effectively improve the passing efficiency of the turnout grinding assembly 1 and avoid the collision between the guide wheel 15 and the switch tip.

[0051] In an example, Figure 1 and Figure 2 As shown, the connecting rod assembly 5 includes a first connecting rod 51 and a second connecting rod 52 rotatably connected thereto, the first end of the first connecting rod 51 is rotatably connected to the first end of the second connecting rod 52, and the second end of the first connecting rod 51 and the second end of the second connecting rod 52 are both rotatably connected to the guide sleeve 2.

[0052] Specifically, the first connecting rod 51 and the second connecting rod 52 are rotatably connected, that is, the first end of the first connecting rod 51 is rotatably connected to the first end of the second connecting rod 52, and the manner of the rotatable connection is not limited. The second end of the first connecting rod 51 and the second end of the second connecting rod 52 are both rotatably connected to the guide sleeve 2, so that the guide sleeve 2 can rotate relative to the connecting rod assembly 5 to adjust the longitudinal position of the turnout grinding assembly 1.

[0053] It should be noted that there may be multiple connecting rods, such as 3, 5, etc., which can be determined in combination with actual operation requirements, as long as the guide sleeve 2 can rotate relative to the connecting rod assembly 5 to adjust the longitudinal position.

[0054] Furthermore, the first connecting rod 51 and the second connecting rod 52 are rotationally connected via a pin shaft 7 .

[0055] In specific applications, when the longitudinal position of the turnout grinding assembly 1 needs to be adjusted, the guide sleeve 2 can be used to rotate around the guide shaft 4, driving the first connecting rod 51 or the second connecting rod 52 to rotate around the pin shaft 7, thereby realizing the relative rotation of the first connecting rod 51 and the second connecting rod 52, that is, realizing the relative adjustment of the longitudinal position of the turnout grinding assembly 1 at both ends of the connecting rod assembly 5.

[0056] In an example, Figures 1 to 6 As shown, a connecting portion 21 is provided on the outer periphery of the guide sleeve 2, and the second end of the second connecting rod 52 and the second end of the first connecting rod 51 are both hinged to the connecting portion 21 of the corresponding guide sleeve 2 through a pin shaft 7, and a cotter pin 8 is provided on the pin shaft 7.

[0057] Specifically, a connecting portion 21 is provided on the outer periphery of the guide sleeve 2, and the connecting portion 21 can form a gap for placing the end of the connecting rod, and the connecting portion 21 is rotatably connected to the connecting rod through the pin 7. The connecting rods here are the first connecting rod 51 and the second connecting rod 52.

[0058] A pin hole is provided on the outer periphery of the pin shaft 7, and the cotter pin 8 is inserted into the pin hole to achieve axial limitation of the pin shaft 7 to prevent the pin shaft 7 from accidentally disengaging due to axial movement, thereby improving the reliability of the adjustment mechanism.

[0059] In an example, Figures 1 to 6 As shown, a guide frame 6 is provided on the outer side of the connecting rod assembly 5 , and the guide frame 6 is used to be connected to the fixing frame 12 , and the guide frame 6 can limit the lateral movement of the connecting rod assembly 5 and adjust the guide for its longitudinal movement.

[0060] Specifically, the guide frame 6 can be connected to the support frame of the turnout grinding device, and the support frame here is the fixed frame 12, so as to support the guide frame 6. The guide frame 6 is vertically provided with a guide channel, and the guide channel can have a certain limit and guide effect on the moving range of the connecting rod assembly 5, that is, limit the lateral movement and guide the longitudinal movement, so as to ensure that the connecting rod assembly 5 can move up and down in the vertical direction in coordination with the guide sleeve 2, and the size of the guide frame 6 is set in coordination with the connecting rod assembly 5.

[0061] The up and down movement of the connecting rod assembly 5 in the guide frame 6 is realized based on the rotation of the guide sleeve 2. Specifically, the longitudinal movement of the turnout grinding assembly 1 can be realized by the driving member of the turnout grinding assembly 1, thereby realizing the rotation of the guide sleeve 2 relative to the connecting rod assembly 5.

[0062] In one example, connecting shafts are provided on both sides of the guide frame 6 , and the connecting shafts are used to connect with the fixing frame 12 .

[0063] Specifically, there are connecting shafts on both sides of the guide frame 6 (located in the elastic member 9 in the figure), the connecting shafts are integrally formed with the guide frame 6, and the connecting shafts are connected to the fixing frame 12 to fix the guide frame 6 on the fixing frame 12 of the turnout grinding device.

[0064] In an example, Figures 1 to 6 As shown, a connecting assembly connected to the fixing frame 12 is provided on the connecting shaft, and the connecting assembly includes a first support 10, a second support 11 and a fastener;

[0065] The first support 10 and the second support 11 can be enclosed in the circumferential direction of the connecting shaft, and the fastener can pass through the first support 10 and the second support 11 and be fixedly connected to the fixing frame 12 .

[0066] Specifically, the connection assembly can realize the connection between the overall frame of the turnout grinding device and the guide frame 6, that is, the connection between the adjustment mechanism and the fixed frame 12. The structural form of the connection assembly is not limited, and it can realize the connection between the connecting shaft and the fixed frame 12.

[0067] The first support 10 and the second support 11 can be closed to fix the connecting shaft, and the fasteners can be passed through the first support 10, the second support 11, and the fixing frame 12 in sequence to achieve a stable connection between the connecting shaft and the fixing frame 12. In this way, the first support 10 and the second support 11 can be arranged to enable the fixing frame 12 to support and fix the guide frame 6, so that the connecting rod assembly 5 can move reliably and stably in the guide frame 6.

[0068] Furthermore, the fasteners are preferably bolts, which are easy to disassemble and assemble.

[0069] In an example, Figures 1 to 6 As shown, an elastic member 9 is sleeved on the connecting shaft, and two ends of the elastic member 9 are respectively connected to the connecting assembly and the guide frame 6.

[0070] Specifically, an elastic member 9 is arranged between the connecting assembly and the guide frame 6. At this time, the axial position of the connecting assembly and the connecting axis is not fixed. The elastic expansion and contraction of the elastic member 9 can realize axial buffering adjustment of the guide frame 6 relative to the connecting assembly along the connecting axis, that is, the guide frame 6 has a certain buffering adjustment ability relative to the fixed frame 12.

[0071] In an example, Figures 1 to 6 As shown, both ends of the guide shaft 4 are provided with connecting flanges 13, and the connecting flanges 13 are used to connect with the turnout grinding assembly 1.

[0072] Specifically, connecting flanges 13 are connected to both ends of the guide shaft 4. Through the setting of the connecting flanges 13, the guide shaft 4 can be stably and reliably connected to the turnout grinding assembly 1. The connecting flanges 13 and the turnout grinding assembly 1 are detachably connected, and can be connected by bolts, screws, etc. A set of turnout grinding assemblies 1 corresponds to one guide shaft 4 and two connecting flanges 13.

[0073] Furthermore, a connecting plate 14 is provided between the guide shaft 4 and the turnout grinding assembly 1 , one end of the connecting plate 14 is connected to the guide shaft 4 , and the other end of the connecting plate 14 is fixed to the turnout grinding assembly 1 .

[0074] Specifically, the connection plate 14 is arranged to be connected to the connection flange 13 on the guide shaft 4, so as to facilitate the connection between the guide shaft 4 and the turnout grinding assembly 1. The connection plate 14 can be a right-angle plate or a straight plate, and can be specifically arranged according to the actual working conditions.

[0075] Example 2

[0076] like Figures 1 to 7 As shown, the turnout grinding device of the present invention comprises at least one of the above-mentioned adjustment mechanisms for the turnout grinding device, a fixing frame 12 and at least two groups of turnout grinding assemblies 1, the adjustment mechanism is connected to the fixing frame 12, and two groups of turnout grinding assemblies 1 are correspondingly connected to both sides of the adjustment mechanism.

[0077] Specifically, the fixed frame 12 is a support frame for the entire turnout grinding device, and needs to have good rigidity and strength to ensure safety and stability during use. The overall size of the fixed frame 12 is not limited here, and is subject to the actual grinding operation requirements. A guide wheel 15 is provided on the turnout grinding assembly 1, and the setting of the adjustment mechanism on the turnout grinding device can make a set of turnout grinding assemblies 1 be provided at the front and rear. When one of the guide wheels 15 in the front and rear groups of turnout grinding assemblies 1 passes through the harmful section, the other guide wheel 15 can be adjusted to fit the rail 16, that is, when the guide wheel 15 of the front turnout grinding assembly 1 is in the harmful space, the guide wheel 15 of the rear turnout grinding assembly 1 always leans against the rail 16, and when the guide wheel 15 of the rear turnout grinding assembly 1 falls into the harmful space, the guide wheel 15 of the front turnout grinding assembly 1 leans against the rail 16 again to ensure that it can pass through the harmful space quickly.

[0078] In this way, multiple groups of turnout grinding assemblies 1 are connected as a whole to pass through the harmful space together, which can improve the efficiency of passing through the harmful space and avoid collision with the switch tip.

[0079] In one example, the turnout grinding device also includes a driving mechanism, a detection mechanism and a control mechanism (not shown in the drawings), the driving mechanism can drive the corresponding components of the adjustment mechanism to perform adjustment or locking actions, the detection mechanism can capture the longitudinal position and lateral position of the turnout grinding assembly 1 in real time, and the control mechanism can control the adjustment mechanism to adjust the position of the turnout grinding assembly 1.

[0080] Specifically, the driving mechanism can drive the guide shaft 4 to move axially to adjust the lateral position of the turnout grinding assembly 1; can drive the guide sleeve 2 to rotate to adjust the longitudinal position of the turnout grinding assembly 1; can drive the hydraulic expansion sleeve 3 to lock or unlock to lock the position of the turnout grinding assembly 1.

[0081] The detection mechanism can use high-precision sensors and image processing technology to capture the longitudinal and lateral positions of multiple groups of turnout grinding assemblies 1 in real time. Specifically, when the turnout grinding device is operating on the turnout, the detection mechanism will continuously scan and identify the relative position relationship between the turnout grinding assembly 1 and the rail 16 and the switch tip. These position data will be transmitted to the control mechanism in real time to provide a basis for its subsequent position adjustment.

[0082] At the same time, after receiving the position data from the detection mechanism, the control mechanism can quickly analyze and process it, and issue a command to adjust the position of the switch grinding assembly 1 through the adjustment mechanism. This adjustment can be longitudinal, transverse, or transverse and longitudinal at the same time, so that when one of the guide wheels 15 of the two switch grinding assemblies 1 on the same adjustment mechanism passes through the harmful section, the other guide wheel 15 is ensured to fit the rail 16.

[0083] In addition, the control mechanism can also be connected to the remote monitoring center to realize remote monitoring and fault diagnosis, further improving the operational reliability and maintenance convenience of the turnout grinding device.

[0084] The introduction of such detection mechanism and control mechanism can make the turnout grinding device have a higher level of intelligence and automation in position capture and position adjustment, thereby ensuring the accuracy and efficiency of grinding and improving the turnout grinding efficiency and passing efficiency.

[0085] In one example, the turnout grinding device may include multiple groups of turnout grinding assemblies 1, and the multiple groups of turnout grinding assemblies 1 are adjusted and locked by an adjustment mechanism, and each group of turnout grinding assemblies 1 is equipped with a guide wheel 15. In this way, when the turnout grinding device passes through the harmful space of the turnout, the multiple groups of turnout grinding assemblies 1 are locked by the adjustment mechanism, and when a guide wheel 15 passes through the harmful space, at least one or more guide wheels 15 are close to the inner side of the rail 16, so that the turnout grinding device can smoothly pass through the harmful space without colliding with the turnout tip.

[0086] In one example, the turnout grinding assembly 1 in the turnout grinding device can adjust the height through an adjustment mechanism, and multiple groups of turnout grinding assemblies 1 can be installed with grinding wheels of different diameters to meet different operating requirements.

[0087] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
