Description

Technical Field

[0001] This application relates to the field of railway track maintenance, and particularly to a ballastless track tie plate grinding vehicle. Background Art

[0002] When high-speed trains operate normally on the line, they are highly sensitive to the TQI (Track Quality Index) value. Therefore, high-speed railways have high requirements for factors affecting the TQI value, such as track elevation, alignment, gauge, level, and cross-level. Due to the long-term operation after the completion of high-speed railways, different degrees of diseases occur in the railway lines, which will lead to changes in the track quality index value. After the TQI value changes, it is a necessary means to maintain and repair the high-speed railway to restore the TQI value to ensure the safety of high-speed train operation.

[0003] For the situation where the line quality caused by the arching disease of the track slab cannot meet the normal operation requirements of high-speed trains, it is necessary to reprocess and repair the tie plate to ensure that the repaired tie plate can meet the line quality requirements for high-speed train operation. For the situation where the track quality index value changes due to small settlement and arching, the track quality index value can be restored by adjusting the rail fastener system to ensure train operation safety.

[0004] For sections with a large amount of arching, which have exceeded the adjustment range of the rail fastener system, the current maintenance construction methods are: one is to rebuild the track slab or the invert arch of the tunnel; the other is the tie plate grinding method. Rebuilding the track slab or the invert arch of the tunnel is to manually remove the roadbed slab, subgrade, etc. under the sleeper and re-make the subgrade and roadbed slab in the tunnel. However, this method has the disadvantages of long construction period, many construction personnel, great difficulty in construction organization, and high maintenance cost.

[0005] Adopting the tie plate grinding method can reduce the track elevation by grinding the tie plate, thereby meeting the requirements of track smoothness and improving the line operation quality. Currently, the patent No. CN218026956U discloses a ballastless track tie plate milling and grinding vehicle that can perform tie plate grinding operation construction. However, when this vehicle is under construction, two identical vehicles need to be coupled to meet the construction organization requirements of high-speed railways. It has the following disadvantages: 1. This vehicle is only equipped with a single crane. When the crane fails and cannot be used, there is no spare crane to recover the grinding device; 2. This vehicle cannot meet the construction requirements of large superelevation on high-speed railways; 3. When this vehicle is under construction, more sleepers need to be added to improve the reliability of its hoisting process.

[0006] In view of this, this application is specifically proposed. Summary of the Invention

[0062] In the present application, the direction along the extension of the track is defined as the longitudinal direction, the direction along the extension of the sleeper is defined as the transverse direction, and the direction perpendicular to the plane where the transverse and longitudinal directions are located is defined as the vertical direction, with the grinding operation direction as the front.

[0063] As Figures 1 - 8 shown, the embodiment of the present application provides a grinding vehicle for the track slab support of the ballastless track, including a flat car and a frame 1, a track slab support grinding device 2, and a lifting device 3; the track slab support grinding device 2 is installed on the flat car and the frame 1; in the working state, the track slab support grinding device 2 is located on the adjacent line of the ballastless track to carry out grinding operations on the track slab support of the ballastless track; the lifting device 3 is installed on the flat car and the frame 1; it is used to lift and place the track slab support grinding device 2 from the flat car and the frame 1 onto the track slab of the adjacent line to be ground, and to lift and place the track slab support grinding device 2 from the track slab of the adjacent line to be ground onto the flat car and the frame 1. When carrying out the lifting and placing operation on a straight track, the flat car and the frame 1 do not need to be leveled left and right; when carrying out the lifting and placing operation on a curve with superelevation, the flat car and the frame 1 need to be leveled left and right by using a leveling frame first before carrying out the hoisting operation of the grinding device.

[0064] The flat car includes: a leveling frame and an end frame. Among them, the leveling frame is used to carry the track slab support grinding device and the lifting device, and adjusts the main body of the flat car to the horizontal position during curve superelevation for hoisting operations; the end frame is arranged at the longitudinal two ends of the leveling frame and is used to carry auxiliary equipment.

[0065] In specific implementation, the grinding vehicle for the track slab support of the ballastless track provided by the embodiment of the present application is mainly used for the grinding operation of the track slab support of the ballastless track. The flat car and the frame 1 are the load-bearing main bodies of the grinding vehicle for the track slab support of the ballastless track. The flat car has systems such as bogies, car bodies, braking systems, and coupler buffer devices. The frame is divided into a leveling frame, a front frame assembly, and a rear frame assembly, which can provide the necessary load-bearing body and basic platform for the transportation and operation of the vehicle. When the vehicle is attached and towed back, the flat car and the frame 1 are the load-bearing bodies of the whole set of equipment, and can conveniently transfer the whole set of equipment; when the vehicle is under construction, the flat car 1 is the basis of the construction organization, is in a stationary state, maintains the water supply and power supply states, and maintains normal grounding to provide the necessary basis for the whole construction operation.

[0066] The rail support table grinding device is lifted by the lifting device 3 to the track slab of the adjacent line where the rail support table to be ground is located; the adjacent line operation mode can be used to carry out the rail support table grinding operation more efficiently and with higher quality. The layout mode of the 301 main crane and the 302 standby crane is adopted. The two cranes can ensure the lifting and recovery of the grinding device, and an auxiliary outrigger 4 is provided. When lifting operations are carried out, the auxiliary outrigger 4 effectively supports the ground, improving the reliability and safety of the construction of the high-speed rail operation line. The leveling frame is used for left and right leveling, which can meet the construction requirements of the high-speed railway curve super-elevation section; at the same time, a method for grinding the rail support table of the ballastless track is provided.

[0067] As Figure 3 shown in Figure 4 Based on the above solution, the embodiment of the present application provides a specific implementation manner of a flat car. The flat car 1 includes a flat car body, a leveling frame 101 and an end frame 102; wherein, the leveling frame 101 is used to carry the rail support table grinding device 2 and the lifting device 3, and adjusts the flat car body to the horizontal position when there is curve super-elevation for lifting operations; the end frame 102 is arranged at the longitudinal ends of the leveling frame and is used to carry auxiliary equipment.

[0068] Specifically, the leveling frame 101 is used to carry the rail support table grinding device 2 and the lifting device 3, and can also be used to adjust the equipment level. When operating in the curve super-elevation section, the leveling frame 101 needs to adjust the entire lifting operation component to the horizontal position before lifting operations can be carried out; the end frame 102 is arranged at the longitudinal ends of the leveling frame 101.

[0069] Specifically, the flat car and the frame 1, as a load-bearing frame, are of a three-section split structure, which can achieve rapid assembly and rapid disassembly, as Figure 3 shown. The middle leveling frame 101 has the functions of loading and leveling, and the end frames 102 at the front and rear ends have the function of loading. In implementation, the leveling frame 101 has the functions of left and right leveling. According to the super-elevation conditions on the inside and outside of the line, automatic leveling is achieved through remote control handle control and switching.

[0070] As a specific implementation manner, the flat car 1 can adopt the NX70 flat car. Other flat car structures that meet the requirements can also be adopted.

[0071] Based on the above solution, the leveling frame 101 includes a bottom connection frame 101, an upper support frame 112, an upper and lower frame connecting beam 112-1 and a connection structure as shown in the figure.

[0072] The bottom connection frame 111 is longitudinally connected to the end frames 102 at both ends. Rectangular frames are provided in the middle of the bottom connection frame 111 and the end frames 102 to achieve lateral and longitudinal constraints on the container lock of the flat car. The upper support frame 112 is arranged above the bottom connection frame 111. Connection structures 113 are arranged on the lateral sides of the leveling frame to connect the bottom connection frame and the upper support frame for mechanical locking. The connection structure 113 is used to achieve secondary mechanical locking between the bottom connection frame and the upper support frame, and can achieve secondary mechanical locking in a non-leveling state or in a leveling state.

[0073] As Figure 4 shown is the schematic diagram of the non-working state; as Figure 5 shown is the schematic diagram of the left leveling state;

[0074] Specifically, an upper and lower frame connecting beam 112-1 is provided between the bottom connection frame 101 and the upper support frame 112; and jacking cylinders are arranged on the left and right sides of the upper and lower frame connecting beam 112-1. The main body of the jacking cylinder is fixedly connected to the upper support frame 112; the output end of the jacking cylinder is hinged to the bottom connection frame 111.

[0075] As a specific implementation manner, jacking cylinders 112-2 are arranged on both the left side and the right side of the upper and lower frame connecting beam 112-1. When in the left leveling state, the jacking cylinder 112-2 on the left side jacks up the upper support frame 112 and the upper and lower frame connecting beam 112-1 at the same time, and the upper and lower frame connecting beam 112-1 and the upper support frame 112 move together. When in the right leveling state, the jacking cylinder 112-2 on the right side jacks up the upper support frame 112, and the upper and lower frame connecting beam 112-1 and the bottom connection frame 111 remain stationary, and only the upper support frame 112 moves upward.

[0076] In specific implementation, the hinged manner can be connected through pin hinge seats 111-1, upper and lower frame connecting beams 112-1, pin hinge structures such as jacking cylinders 112-2, etc. to achieve left and right leveling of the upper support frame 112.

[0077] In specific implementation, the connection structure includes a connection seat 113 and a connection screw 114. The connection seat 113 is arranged on the bottom connection frame and the upper support frame, and the opening of the connection seat faces away from the leveling frame. The connection screw 114 extends in the vertical direction; a connection shaft is correspondingly arranged on the connection screw for the connection seat. Connection holes are arranged on both the connection shaft and the connection seat; connection bolts are embedded in the connection holes to fixedly connect the connection shaft and the connection seat.

[0078] Specifically, the connecting seat 113 is arranged on the bottom connecting frame 111, the connecting screw 114 is arranged on the upper support frame 112, and the connecting seat 113 is provided with an opening facing away from the leveling frame 101; the connecting screw 114 can rotate along the pin shaft of the mounting seat; a connecting shaft 115 is correspondingly arranged on the connecting screw 114; connecting holes are arranged on both the connecting shaft 115 and the connecting seat 113; a connecting bolt is inserted into the connecting hole to fixedly connect the connecting shaft 115 and the connecting seat 113.

[0079] A groove is formed at one end of the end frame facing the leveling frame; protruding portions are correspondingly arranged at the longitudinal two ends of the upper support frame and are corresponding to the groove; the mating surface of the groove and the protruding portion is inclined.

[0080] On the basis of the above solution, a groove 121 is formed at one end of the end frame 102 facing the leveling frame 101; protruding portions are correspondingly arranged at the longitudinal two ends of the bottom connecting frame 111 and are corresponding to the groove 121; the mating surface of the groove 121 and the protruding portion is inclined. Specifically, the longitudinal connection between the frames adopts a "concave-convex" structure for connection, which can achieve rapid assembly and rapid disassembly. The mating surface of the groove 121 and the protruding portion is inclined, restricting a certain angle of the mating part relative to the vertical plane to ensure good contact after positioning.

[0081] As Figure 8 shown, on the basis of the above solution, an embodiment of the present application provides a specific implementation manner of a crosstie grinding device. The crosstie grinding device 2 includes a crosstie grinding frame 201, traveling wheels 202 and a grinding mechanism 203.

[0087] Specifically, the auxiliary outrigger 4 adopts an outrigger with functions such as horizontal telescoping, vertical flipping, and vertical support. The auxiliary outrigger 4 with these functions belongs to the prior art, so the specific structure of the auxiliary outrigger 4 will not be elaborated.

The telescopic length of the outrigger can be adjusted and locked according to the line conditions, and it can meet the requirements of different operation scenarios such as subgrade, tunnel, and bridge.

The pipeline retracting and deploying device 7 is installed at the end of the vehicle and can extend the cables and water pipes to both sides of the vehicle body according to needs to meet the energy supply requirements for the grinding device operation on any side of the vehicle body.

[0089] Specifically, the catenary pedestal grinding device has no self-propelling ability and needs to be towed by a rail vehicle to the operation site, and it is powered by a self-provided generator set.

[0095] (3) The rail support grinding device 2 performs grinding operations on the rail support of the ballastless track on the adjacent line.

[0096] In the specific implementation, the auxiliary legs 4 and the legs of the lifting device 3 are first extended to support the ballastless track line, the vehicle reinforcement measures are released, and whether to level the vehicle is selected according to the superelevation of the line. Then, the main crane 301 is used to lift the rail bearing platform grinding device 2 onto the adjacent ballastless track line. The pipeline retracting and releasing device 7 is used as an energy transmission device to provide the necessary power supply and pressurized water. The rail bearing platform grinding device 2 performs the rail bearing platform grinding operation on the adjacent ballastless track line.
