Description

Technical Field

[0001] The present application relates to the technical field of railway engineering machinery, and in particular to a multifunctional automated rail grinding device for rail grinding. Background Art

[0002] During train operation, rails are exposed to harsh working conditions for long periods of time. Due to multiple factors, including dynamic forces, the natural environment, and the quality of the rails themselves, the rail surface conditions continue to deteriorate and the rail heads deform, resulting in defects such as wave wear, fat edges, spalling, rail surface scales, and rail joint bottom collapse, which seriously affect driving safety. Rail grinding can remove uneven rail surfaces and restore the rail head to its original design requirements, thereby effectively improving the wheel-rail relationship, slowing the development of rail surface defects, improving rail surface smoothness, and extending the service life of the rails. The rail grinding vehicle is a type of track engineering equipment used to remove rail defects. Specifically, it can be used to eliminate defects such as wave wear, fat edges, spalling, rail surface scales, and rail joint bottom collapse that occur during rail use.

[0006] Prior art 3 is a Chinese invention application filed by Zhuzhou Times Electronic Technology Co., Ltd. on January 20, 2020, and published on June 5, 2020, with publication number CN111235982A. The invention discloses a rail grinding trolley, comprising: two grinding trolleys connected in an articulated manner. The grinding trolley comprises: a frame, a grinding unit, a running guide wheel, a dust collection channel, and a fire and dust prevention device. The grinding unit is arranged inside the frame, the running guide wheel is arranged at the lower part of the frame, and the dust collection channel is arranged at the upper part of the frame. The fire and dust prevention device is covered on the outside of the frame except the bottom, and a semi-enclosed structure of the grinding trolley is formed by the fire and dust prevention device and the dust collection channel. The rail grinding trolley also includes an elastic traction rod and a rigid traction rod, one of the grinding trolleys is connected to the car body by an elastic traction rod, and the other grinding trolley is connected to the car body by a rigid traction rod. The invention can solve the technical problems of the existing rail grinding trolley, such as limited application occasions, poor operating stability, and poor grinding quality and effect.

[0007] The structures of the polishing trolleys of the above-mentioned prior arts 1-3 are basically similar. Such polishing trolley structural designs have the following disadvantages:

[0008] 1) The grinding trolley has no power and must be installed at the bottom of the train. The whole train provides traction power and grinding power to complete the rail grinding operation;

[0009] 2) The grinding car is large in size, complex in structure and equipment, and expensive;

[0010] 3) The trolley grinding unit has no transverse movement function;

[0011] 4) The grinding carriage is generally designed with 8 or 10 grinding heads. The number of grinding heads cannot be changed, and the overall space utilization is low;

[0012] 5) The grinding carriage is bulky and the grinding unit and grinding motor are difficult to maintain;

[0013] 6) The grinding trolley cannot complete the reciprocating grinding of rails within a short distance;

[0014] 7) The grinding motor of the grinding trolley directly drives the grinding wheel to grind the rails, causing the motor to be subjected to large axial impact during operation, thereby reducing the service life of the grinding motor.

[0015] Prior art 4 is a Chinese invention application filed by Beijing Jiaotong University on June 7, 2021, and published on September 7, 2021, with publication number CN113355960A. This invention discloses a self-driven intelligent belt grinder. It includes: a belt wheel system, a tensioning mechanism, a lifting mechanism, a transverse deflection linkage mechanism, and a whole-machine travel drive mechanism. The driving wheel in the belt wheel system is connected to the drive motor in the tensioning mechanism, the contact wheel bracket in the belt wheel system is connected to the contact wheel bracket mounting plate in the lifting mechanism, the column in the transverse deflection linkage mechanism is connected to the lifting guide column in the lifting mechanism via a connecting rod, and the whole-machine travel drive mechanism is connected to the belt wheel system, tensioning mechanism, lifting mechanism, and transverse deflection linkage mechanism via a frame. The whole-machine travel drive mechanism relies on the hub motor and wheels in the whole-machine travel drive mechanism to cross the rails. The grinder of this invention achieves belt tensioning through the elastic force of a strong spring under the motor mounting frame, making the structure compact. By linking the deflection and lateral movement mechanisms and adjusting the grinding mechanism to above the predetermined grinding position, grinding can be completed in a large angle range from the inside to the outside along the rail profile.

[0016] The polishing trolley structure design of the above-mentioned prior art 4 has the following disadvantages:

[0017] 1) The grinding machine has low power, simple structure and function, low performance and efficiency, small single cutting volume and can only grind one side of the rail at a time, resulting in low overall efficiency;

[0018] 2) The grinder needs to be pushed manually and uses an internal combustion engine to drive the grinding wheel, which produces a lot of noise and a low grinding speed. A single device must be operated by one person;

[0019] 3) The grinding machine's lateral movement, deflection, and downward pressure actions all require manual operation, and the degree of automation is low;

[0020] 4) The grinding machine uses a single grinding wheel, which has low operating efficiency. When using a sanding belt for grinding, the sanding belt is easy to deviate and leave the wheel groove;

[0021] 5) The grinding machine has no dust collection equipment, and the iron chips and dust from the rail grinding fall onto the sleepers or the sleeper bed;

[0022] 6) The grinding machine uses manual pushing during the reciprocating grinding process, which is inefficient and has low operating accuracy. Summary of the Invention

[0023] In view of this, the purpose of this application is to provide a rail grinding equipment to solve the technical problems that the existing equipment has no self-propelled motion, the whole vehicle equipment is complex, expensive, and bulky in structure, and cannot achieve short-distance reciprocating grinding, or the grinding power is small, the whole vehicle efficiency is low, the degree of automation is not high, and the operation is inconvenient.

[0043] Furthermore, rail-supporting devices are provided on both the front and rear sides of the frame, each including rail-supporting wheels. During the mainline grinding phase, the rail-supporting devices are inactive, and the rail-supporting wheels are positioned away from the stock rail. Before switch grinding, the rail-supporting device on the side closest to the stock rail is activated, causing the rail-supporting wheels to rest against the inner side of the stock rail.

[0047] Furthermore, when the handle is raised, it drives the hinge rod and one end of the handle hinge rod, along with the handle's movable axis, upward. The sliding rod is stretched inward, driving the rail-adjacent rod inward. Under the action of the return spring and rail-adjacent spring, the sliding seat slides inward, driving the rail-adjacent wheel to contact the inner side of the rail, achieving rail-adjacent motion. Simultaneously, the handle is self-locking and remains raised in the absence of external force.

[0096] The rail grinding equipment 100 also includes a wireless transmission device 29 mounted on and wirelessly connected to the control system 7. The wireless transmission device 29 is used to transmit wireless control commands and data. A worker sends control commands and data to the rail grinding equipment 100 via an operator terminal. These commands and data are received by the wireless transmission device 29 and sent to the control system 7.

[0097] As a typical specific embodiment of the present application, the rail grinding equipment 100 adopts a left-right symmetrical structure and includes two sets of batteries 3, control systems 7 and grinding units 12 symmetrically arranged above the frame 1 and located on the left and right sides of the frame 1. The grinding unit 12 is located between the battery 3 and the control system 7. The control system 7 is installed at the end of the frame 1 and is fixed to the box at the end of the frame 1 through a quick-release structure. The grinding unit 12 is installed in the frame 5 on the left and right sides of the frame 1, and a grinding motor 18 is installed in the grinding unit 12. The transverse frame 14 of the grinding unit 12 is connected to the frame 1 and the frame 5 through a transverse motion pair, a transverse drive mechanism 9 and a limit device to achieve transverse movement on the frame 1. The grinding motor 18 is installed on the transverse frame 14. A single grinding motor 18 can be moved up and down on the grinding unit frame 17 through the downward driving mechanism 19. The grinding unit frame 17 is installed on the transverse frame 14 through the rotating shaft (pin) 30, and the deflection of the grinding unit 12 relative to the transverse frame 14 is achieved through the deflection driving mechanism 16 (which can specifically adopt a deflection electric cylinder).

[0098] As attached Figure 10 To the attached Figure 15As shown, the grinding unit 12 also includes a transverse frame 14, a crossbeam 15, a deflection drive mechanism 16, a grinding unit frame 17 and a downward pressure drive mechanism 19. The first transverse assembly 10 and the second transverse assembly 11 are arranged between the vehicle frame 1 and the transverse frame 14, and the transverse drive mechanism 9 is arranged between the frame body 5 and the transverse frame 14. The grinding unit frame 17 is pivotally connected to the transverse frame 14 via a rotating shaft 30, and the crossbeam 15 is fixed to the grinding unit frame 17. The grinding motor 18 is movably connected to the grinding unit frame 17 via a rotating arm 33. One end of the downward pressure drive mechanism 19 is connected to the grinding motor 18, and the other end is connected to the crossbeam 15. One end of the deflection drive mechanism 16 is connected to the transverse frame 14, and the other end is connected to the deflection mounting seat 32 of the grinding unit frame 17. The downward pressure drive mechanism 19 can drive the grinding motor 18 to perform the downward pressure operation and act on the rail 20. The deflection drive mechanism 16 can drive the grinding motor 18 (which can be specifically a downward pressure electric cylinder) to perform a deflection operation around the rotating shaft 30 along the direction shown by T in the accompanying drawing, thereby realizing the deflection of the grinding motor 18 relative to the rail 20 to meet the grinding requirements at different angles during the operation process.

[0099] The traverse frame 14 is mounted on the vehicle frame 1 via guide rails and sliders, and the frame 5 is mounted on the vehicle frame 1. One end of the traverse drive mechanism 9 is mounted on the traverse frame 14, and the other end is mounted on the frame 5. The traverse drive mechanism 9 drives the traverse frame 14 to move laterally, simultaneously enabling the traverse movement of the grinding head 35 of the grinding motor 18 relative to the rail 20. One end of the deflection drive mechanism 16 is mounted on the traverse frame 14, and the other end is mounted on the grinding unit frame 17. Through the action of the deflection drive mechanism 16, the grinding unit 12 can be deflected relative to the rail 20, allowing grinding operations at different angles during operation. One end of the downward pressure drive mechanism 19 is mounted on the grinding unit frame 17, and the other end is mounted on the motor mounting frame 21. Through the action of the downward pressure drive mechanism 19, the vertical position (as indicated by the direction H in the accompanying drawings) of the grinding motor 18 relative to the rail 20 can be changed, allowing the grinding head 35 to press down and act on the rail 20. The grinding motor 18 is installed on the motor mounting frame 21, and the grinding head 35 is installed on the grinding head drive shaft 50 in the motor mounting frame 21. The grinding motor 18 drives the grinding head drive shaft 50 to rotate through the action of the flat key, so that the grinding head 35 produces relative movement relative to the rail 20, thereby realizing the rail grinding operation.

[0100] As attached Figure 16As shown, a motor mounting frame 21 is fixed to the grinding motor 18, and one end of the downward driving mechanism 19 is connected to the motor mounting frame 21. One end of the rotating arm 33 is hinged to the motor mounting frame 21, and the other end is hinged to the grinding unit frame 17. A motor mounting plate 36 is fixed below the grinding motor 18, and a cylinder 40 is provided below the motor mounting plate 36. The cylinder 40 is welded and fixed to the motor mounting frame 21 as a whole. The motor mounting frame 21 includes a first side plate 34 and a second side plate 39 that are arranged opposite to each other and parallel in the horizontal direction, and a first horizontal plate 37 and a second horizontal plate 38 that are connected between the first side plate 34 and the second side plate 39 and are arranged opposite to each other and parallel in the vertical direction. The cylinder 40 is passed through the first horizontal plate 37 and the second horizontal plate 38 and is fixed to the first horizontal plate 37 and the second horizontal plate 38.

[0101] As attached Figure 17 As shown, a first bearing 47 and a second bearing 48 are sleeved on the grinding head drive shaft 50, which are secured to the interior of the cylinder 40 via a cover plate 43. The other end of the grinding head drive shaft 50 extends out of the cylinder 40 and is connected to the grinding head 35 via a fastener 74. A first sealing ring 45 is provided between the cover plate 43 and the grinding head drive shaft 50, and a second sealing ring 49 is provided between the second bearing 48 and the cylinder 40. Within the cylinder 40, the motor shaft 41 of the grinding motor 18 is connected to one end of a sleeve 42 via a first flat key 44. The other end of the sleeve 42 is connected to one end of the grinding head drive shaft 50 via a second flat key 46.

[0102] As a typical embodiment of the present application, the grinding unit 12 further includes two grinding motors 18 longitudinally mounted on the grinding unit frame 17, with the crossbeam 15 fixed to the middle of the grinding unit frame 17. The upper and lower portions of the left and right motor mounting brackets 21 are movably connected to the grinding unit frame 17 via rotating arms 33. The grinding unit 12 is mounted on the left and right sides of the middle portion of the vehicle frame 1.

[0103] As attached Figure 1 To the attached Figure 9As shown, rail rest devices 13 are further provided on the left and right sides of the front and rear parts of the vehicle frame 1, and the rail rest devices 13 include rail rest wheels 70. In the main line grinding state, the rail rest device 13 does not operate, and the rail rest wheels 70 are away from the basic rail. Before the turnout is ground, the rail rest operating handle (i.e., the handle 51) close to the side of the basic rail is manually lifted, and the rail rest device 13 close to the side of the basic rail is actuated, so that the rail rest wheels 70 are close to the inner side of the basic rail, thereby limiting the serpentine motion of the rail grinding equipment 100 during the turnout operation, and ensuring that the rail grinding equipment 100 safely passes through the harmful space and the switch center position. The rail grinding equipment 100 described in the specific embodiment of the present application has a low constant speed self-propelled function, which can meet the grinding requirements of various lines such as the main line and the turnout, and realize the short-distance reciprocating grinding requirements. At the same time, the rail grinding equipment 100 has the function of ensuring that the grinding unit 12 does not make serpentine motion during the switch grinding process, can ensure that the grinding head 35 does not change significantly in the lateral position relative to the rail 20, and has the advantages of simple manual operation, stability and reliability, and low cost.

[0104] As attached Figure 18 To the attached Figure 21 As shown, the rail-resting device 13 also includes a handle 51 (i.e., a rail-resting operating handle), a handle base 54, a rail-resting rod 60, a sliding rod 65, and a sliding seat 66. When the rail-resting operating handle is manually operated, the rail-resting action can be achieved. The rail-resting rod 60 is movably inserted into the first rail-resting rod seat 59 and the second rail-resting rod seat 62. The sliding rod 65 is movably inserted into the sliding seat 66 and is fixed to the vehicle frame 1 via sliding rod seats 64 respectively provided at both ends of the sliding rod 65. The sliding seat 66 is also fixed to the bottom of the second rail-resting rod seat 62. The sliding seat 66 can slide axially along the sliding rod 65. The rail-resting wheel 70 is movably mounted on the inner side of the sliding seat 66 via the rail-resting wheel shaft 67. A rail-resting spring 63 is provided on the rail-resting rod 60. The rail-resting spring 63 is also located between the flange at one end of the rail-resting rod 60 and the second rail-resting rod seat 62. A return spring 61 is also sleeved on the rail pull rod 60, and the return spring 61 is also located between the second rail pull rod seat 62 and the first rail pull rod seat 59. The first rail pull rod seat 59 and the handle base 54 are both fixed to the frame 1. The handle 51 is movably set on the handle base 54, and the other end of the rail pull rod 60 is movably connected to the handle 51. At least two sliding rods 65 arranged in parallel in the horizontal direction are movably inserted into the sliding seat 66, and the two sliding rods 65 are connected and fixed by the sliding rod seat 64. The rail wheel shaft 67 is movably mounted on the sliding seat 66 through the first bearing 68 and the second bearing 69 sleeved thereon. The rail wheel 70 is fixed to one end of the rail wheel shaft 67 by a pressure cover 71, and the other end of the rail wheel shaft 67 is fixed to the sliding seat 66 by a second fastener 75.

[0105] As attached Figure 22 and attached Figure 23 As shown, the handle base 54 is provided with a hinge rod shaft 53 and a handle shaft 55. The handle 51 is hinged to the handle shaft 55, and a slot 73 is formed in the handle 51. One end of the rail pull rod 60 is connected to one end of the sliding pull rod 58 via a connecting nut 72. The other end of the sliding pull rod 58 is hinged to one end of the pull rod hinge rod 57. One end of the handle hinge rod 52 is provided with a handle movable shaft 56, and the other end is hinged to the hinge rod shaft 53. The other end of the pull rod hinge rod 57 is hinged to the handle movable shaft 56, which is also located in the slot 73.

[0106] As attached Figure 24 and attached Figure 25 As shown, one end of the rail tie rod 60 is connected to one end of the sliding rod 58 via a connecting nut 72. The rail tie device 13 is disposed on both the left and right sides of the front and rear portions of the vehicle frame 1. A mounting plate 76 is provided on the vehicle frame 1, and the first rail tie rod seat 59 and the handle base 54 are both secured to the upper portion of the mounting plate 76. The sliding seat 66 passes through a mounting hole 77 defined in the mounting plate 76 and is secured to the lower portion of the mounting plate 76 via the sliding rod seat 64.

[0107] The handle base 54, the first rail-resting rod seat 59, and the sliding rod seat 64 are all fixed to the vehicle frame 1 by bolts. The sliding rod 58 and the rail-resting rod 60 are connected and fastened by a connecting nut 72. The second rail-resting rod seat 62 is fixed to the sliding seat 66. When the handle 51 is raised, the handle 51 drives the rod hinge rod 57 and one end of the handle hinge rod 52, together with the handle movable shaft 56, to move upward. The sliding rod 58 is stretched toward the inside (as shown by B in the accompanying drawings, and the outside is shown by A in the accompanying drawings), driving the rail-resting rod 60 to move inward. Under the action of the return spring 61 and the rail-resting spring 63, the sliding seat 66 slides inward and drives the rail-resting wheel 70 to press against the inside of the rail 20 (i.e., the base rail), achieving the rail-resting action. The rail-resting device 13, in conjunction with the grinding unit 12, is used in turnout grinding operations or other turnout operating equipment to maintain the running wheels (i.e., wheelset) in a relatively stable position relative to the stock rail, ensuring that the operating equipment does not interfere with or damage the turnout during operation. When the handle 51 is lifted upward, the sliding seat 66 moves toward the inside of the rail 20, driving the rail-resting wheel 70 to adhere to the inner surface of the rail 20. At the same time, the handle 51 is in a self-locking state and remains raised in the absence of external force.
