A method for greasing sleeper bolts

Abstract

The present invention discloses a method for lubricating sleeper bolts. After the integrated operation vehicle arrives at the operation site, the locking mechanism is first opened, and the lifting drive mechanism is synchronously extended, driving the main frame to lower the rail oiling mechanism. When the rail wheel assembly contacts the rail, the rail drive mechanism releases pressure, and the rail wheel assembly moves under the action of the compression spring, and ensures that the wheel flange of the rail wheel contacts the inner side of the rail to complete the rail-resting action. The oil injection assembly turns on the sleeper bolt signal detection and nozzle control. After the lubrication operation is completed, the rail drive mechanism stretches, driving the rail wheel to separate from the inner side of the rail, and the lifting drive mechanism drives the rail oiling mechanism to rise, and the rail drive mechanism releases pressure. The rail wheel assembly moves under the action of the compression spring to lock the locking mechanism with the main frame. The present invention can solve the technical problems of the existing bolt oiling maintenance operation method, such as high labor intensity, high labor cost, low operation efficiency, and incompatibility with the large-scale line maintenance machine system.

Description

Technical Field

[0001] The present invention relates to the technical field of railway construction machinery, and particularly relates to a vehicle-mounted oiling operation method for a large comprehensive maintenance train to perform oiling maintenance on rail bolts. Background Art

[0002] With the speed increase and heavy-haul of railways, the requirements for railway lines are constantly improving. Therefore, during the construction and maintenance operations of modern railways, a large number of large-scale and highly automated mechanical equipment are widely used, such as: bridge erecting machines, track laying machines, tamping machines, ballast cleaning machines, rail grinding machines, ballast profiling machines, etc. At present, the mechanization and automation levels of the main operations in railway line construction and maintenance are already very high, and the operation quality has also reached a relatively high level. However, in some non-maintenance operations, such as the maintenance of sleeper bolts, manual operations are still mostly adopted. This maintenance method not only has a large labor intensity and low operation efficiency, but also many human factors are difficult to control. Therefore, the maintenance quality of sleeper bolts is relatively low. With the formation of the current pattern of high-speed and high-density railway lines, to ensure the safe and stable operation of line equipment, good maintenance is the key. To prevent the vertical bolts on both sides of the rail from rusting, it is necessary to often oil the rail bolts. Bolting not only keeps the bolts in good condition and prevents rust, but also facilitates the loosening and tightening of daily operations, maintains the track geometry and the stiffness of the track frame, extends the service life of the equipment, and at the same time ensures the safe and stable operation of the train. Currently, when oiling the fasteners, it is generally carried out during the railway skylight period. A small mop or small brush is carried by hand to oil the fasteners. At the same time, it is necessary to manually pull the flat car for loading the oil barrel, and then other people use a small mop or small brush respectively to oil the fasteners on one side of the two railway tracks. Due to the long length of the railway line, such an oiling method will waste a large amount of labor, and at the same time, the oiling efficiency is low, the operation quality and standards are difficult to guarantee, and it is also difficult to quickly oil the fasteners along the railway line. Although some semi-manual oiling operations using small hand-pushed bolt oiling equipment save the labor of workers to a certain extent, most of them do not have the function of accurately detecting and positioning the fasteners, and manual adjustment of the positioning is required. Moreover, the one-person-one-car oiling operation does not significantly improve the operation efficiency, and the mutual cooperation does not avoid the window period operation mode, and it is difficult to be compatible with the track maintenance operations of other large machine systems.

[0003] In the prior art, the following technical solutions are mainly related to the present invention:

[0004] The prior art 1 is a Chinese invention application filed by Wuhan University of Technology on June 5, 2017, and published on October 3, 2017, with the publication number CN107227664A. This invention discloses an automatic screwing and oiling trolley for railway track bolts, including a traveling device, on which a frame is provided. On the frame, there are a bolt detection sensor, a bolt screwing device, and a bolt oiling device. The bolt screwing device includes a carrying platform, on which a lead screw vertical movement mechanism is provided. The carrying platform is threadedly connected to the lead screw of the lead screw vertical movement mechanism. At least one set of X-Y adjustment platforms is movably connected to the carrying platform. At the lower end of the adjustment platform, a bolt screwing machine is connected. The bolt screwing machine includes a bolt screwing drive motor, a torque controller, and a bolt centering guide sleeve arranged in sequence from top to bottom. Although this trolley has a high degree of automation, saves manpower, and improves the efficiency of railway maintenance compared with the existing bolt screwing devices, for the automatic screwing and oiling operations of track bolts, this invention requires two sets of devices, namely a bolt screwing device and a bolt oiling device, to complete, resulting in a complex overall structure and poor economy, and still needs further improvement.

[0005] The prior art 2 is a Chinese invention application filed by Wuhan University of Technology on June 5, 2017, and published on October 27, 2017, with the publication number CN 107299565A. This invention discloses a railway track maintenance machine based on the cooperative working mode of a master machine and a slave machine, including a host computer, a master machine, and a slave machine. On the master machine, there are an unevenness detection module, a defect detection module, and a bolt loosening detection module. On the slave machine, there are a bolt screwing device, an oiling device, a grinding machine, and a back-check device. The unevenness detection module and the defect detection module are respectively connected to the host computer, and the host computer is used to control the bolt screwing device, the oiling device, the grinding machine, and the back-check device. Although this maintenance machine is small in size, has a high degree of integration, automation, and intelligence, and high efficiency, saves manpower, changes the traditional separated maintenance working mode, realizes the collaborative operation of detection and maintenance in railway daily maintenance, reduces the cost required for daily maintenance, and improves the working efficiency of maintenance, etc. However, for the automatic screwing and oiling operations of track bolts, this invention requires two sets of devices, namely a bolt screwing device and an oiling device, to complete, resulting in a complex overall structure and poor economy, and still needs further improvement.

[0006] Prior Art 3 is a Chinese invention application filed by China Railway Construction High-Tech Equipment Co., Ltd. on June 7, 2018, and published on October 19, 2018, with publication number CN108677630A. This invention discloses a railway fastener maintenance trolley primarily used for lubricating railroad spikes. The trolley frame is equipped with several operating units, including an operating wrench and a bidirectional oil spray mechanism for the operating wrench. The trolley is connected to the vehicle body using hydraulic cylinders and utilizes a satellite trolley to perform continuous bolt tightening and oiling operations during onboard operations. It can be integrated with large-scale road maintenance machinery for intelligent maintenance operations, or equipped with a power source to independently perform both tightening and oiling maintenance operations on railroad spikes. The oiling mechanism is integrated into the bolt tightening device, and the positioning of all railroad spikes is controlled by multiple sets of hydraulic cylinders in different directions. While this trolley boasts a high level of integration, improving railway maintenance efficiency, the highly integrated structure required for combining bolt tightening and oiling results in a complex control scheme, poor economic efficiency, and a low cost-performance ratio. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a method for oiling sleeper bolts to solve the technical problems of the existing bolt oiling maintenance operation method, such as high labor intensity, high labor cost, low operation efficiency, and incompatibility with the line maintenance machine system.

[0008] In order to achieve the above-mentioned object of the invention, the present invention specifically provides a technical implementation scheme of a sleeper bolt oiling operation method, comprising the following steps:

[0009] S10) After the integrated operation vehicle arrives at the operation site, before carrying out the oiling operation, the locking mechanism is first opened;

[0010] S11) The lifting drive mechanisms on the left and right sides extend synchronously, driving the main frame to lower the rail oiling mechanism;

[0011] S12) When the rail-leaning wheel assembly of the rail-leaning oiling mechanism contacts the rail, the rail-leaning driving mechanism releases pressure, and the rail-leaning wheel assembly moves under the action of the compression spring, ensuring that the wheel flange of the rail-leaning wheel assembly contacts the inner side of the rail, thereby completing the rail-leaning action;

[0012] S13) detecting the signal of the rail sleeper bolts and controlling the nozzle of the oil spraying assembly of the rail lubricating mechanism;

[0013] S14) After the oiling operation is completed, the rail driving mechanism stretches, driving the rail wheel to separate from the inner side of the rail, the lifting driving mechanism drives the rail oiling mechanism to rise, the rail driving mechanism releases pressure, and the rail wheel assembly moves under the action of the compression spring, locking the locking mechanism with the main frame.

[0014] Further, connect the upper end of the anti-derailment chain to the vehicle frame, and connect the lower end to the cross beam through the anti-derailment chain interface in the non-operating mode, so as to prevent the derailment and dropping of the rail-side oiling mechanism. In the step S10), before the oiling operation, release the anti-derailment chains on both sides of the vehicle frame, and then open the locking mechanism. In the step S14), after the oiling operation is completed, first lock the locking mechanism to the main vehicle frame, and then connect the anti-derailment chain to the cross beam.

[0015] Further, the main vehicle frame includes a first fixed frame and a cross beam. Install the first fixed frame at the bottom of the vehicle frame. Connect the upper part of the lifting drive mechanism to the vehicle frame, and connect the lower part to the cross beam. The cross beam moves up and down relative to the first fixed frame under the drive of the lifting drive mechanism. Install the rail-side oiling mechanism on both the left and right sides of the cross beam to realize the rail-side traveling and the oiling operation of the sleeper bolts. Set one end of the locking mechanism on the cross beam to lock the first fixed frame and the cross beam in the non-operating mode.

[0016] Further, the main vehicle frame further includes a guiding mechanism and a stretching mechanism. Hinge the guiding mechanism to the first fixed frame and the cross beam respectively, and connect the stretching mechanism between the first fixed frame and the guiding mechanism. Hinge the upper part of the lifting drive mechanism to the vehicle frame and the lower part to the cross beam. The guiding mechanism is used for guiding the cross beam during the lifting process, supporting it during the lateral movement process, and pulling it during the traveling process. The guiding mechanism includes a guide post, a protective cover, a guide sleeve and a first mounting seat, and an inclination sensor is installed on the first mounting seat. Sheath the protective cover outside the guide post, and sheath the guide sleeve on the protective cover. Fix the first mounting seat on the outer side of the guide sleeve, hinge the lower part of the guide post to the cross beam, and hinge the first mounting seat to the first fixed frame. The stretching mechanism includes a second mounting seat, a tension spring and a pin shaft. Connect the two ends of the tension spring in the length direction to the second mounting seat through the pin shaft. Fix one end of the tension spring to the first mounting seat through the second mounting seat, and fix the other end to the first fixed frame through another second mounting seat for limiting and resetting when the guiding mechanism yaws.

[0017] Further, when the sleeper bolt oiling device is operating on a curve, the center of the vehicle frame is offset relative to the center of the rail. At this time, the guiding mechanism and the stretching mechanism perform adaptive lateral yaw to ensure that the rail-side wheel assembly is always in contact with the rail, so as to realize the curve operation.

[0018] Further, when the sleeper bolt oiling device is operating on a curve, the lateral movement amount of the rail-side oiling mechanism and the inclination angle

[0019]

[0020]

[0021] Among them, is the distance from the upper rotation point to the guide post, is the distance between the upper rotation point and the lower rotation point in the vertical direction, is the inclination angle of the guide post, is the distance from the upper rotation point to the lower rotation point, is the distance from the lower rotation point to the distance of is the included angle with the horizontal direction, is and the included angle of is when turning angle, the horizontal translation distance of the lower rotation point, is the radius of the line curve, is the front wheel of the railway engineering operation vehicle point and the rear wheel the distance between points, point is the installation position of the sleeper bolt greasing device, is to pass point to make a line segment the perpendicular line of, the distance between the foot of the perpendicular and point point.

[0022] Furthermore, the first fixing frame includes a longitudinal beam and a main cross beam, and the longitudinal beam is arranged at both ends of the main cross beam along the length direction. A positioning hole is arranged at one end of the longitudinal beam along the length direction, and a connecting plate is arranged at the other end. Mounting holes are arranged at both ends of the main cross beam along the length direction. The first mounting seat is hinged to the mounting hole, one end of the tension spring is fixed to the outer side of the longitudinal beam through the second mounting seat, and one end of the locking mechanism is arranged on the main cross beam. The cross beam includes a main beam, and hanging rings, positioning pin columns and second hinge seats that are symmetrically arranged left and right along the transverse direction on the main beam. First hinge seats connected to the lifting drive mechanism are arranged at both ends of the main beam along the transverse direction. The lower part of the guide post is connected to the main beam through the second hinge seat, and the hanging ring is used for hanging with the locking mechanism in the non-operation mode. The positioning pin column is matched with the positioning hole at the lower part of the longitudinal beam to realize the rapid positioning of the main beam and the first fixing frame during the rising process of the cross beam.

[0023] Furthermore, lubricating oil application mechanisms for the guide rails are symmetrically installed at the lower parts of the left and right ends of the cross beam in the transverse direction. Each lubricating oil application mechanism for the guide rail further includes a second fixing bracket, a torsion spring, and a swing rod. The second fixing bracket is installed below the cross beam, and a transverse guide post is arranged on the second fixing bracket. The guide rail wheel assembly is movably arranged on the transverse guide post. The guide rail driving mechanism is arranged between the second fixing bracket and the guide rail wheel assembly. The guide rail wheel assembly is driven by the guide rail driving mechanism to move along the transverse guide post to realize the action of approaching the rail. One end of the swing rod is movably installed on the guide rail wheel assembly through a rotating shaft, and the other end is hinged to the oil injection assembly to realize the swing and reset of the oil injection assembly. The oil injection assembly is used for the detection, positioning, and lubricating oil application of the bolts. A height sensor for measuring the distance between the lubricating oil application mechanism for the guide rail and the rail surface is installed on the guide rail wheel assembly. The compression spring is arranged on the transverse guide post and kept between the second fixing bracket and the guide rail wheel assembly to provide the approaching pressure for the guide rail wheel assembly. The torsion spring is arranged on the rotating shaft and kept between the guide rail wheel assembly and the swing rod to provide the restoring force for the reset of the swing rod.

[0024] Furthermore, during the lubricating oil application operation in step S13), when the oil injection assembly encounters an obstacle on the line, the linkage mechanism formed by the swing rod and the oil injection assembly swings back and forth along the line direction to avoid the obstacle. After passing through the obstacle, the swing rod is reset under the action of the torsion spring.

[0025] Furthermore, the oil injection assembly further includes a protective cover, a detection sensor, and a third mounting seat. The third mounting seat is installed inside the protective cover, and the nozzle is installed on the third mounting seat and connected to the fuel tank. The detection sensor is installed inside the protective cover for the detection and positioning of the sleeper bolts. Two sets of oil injection assemblies are symmetrically arranged on the left and right sides of the guide rail wheel assembly. The detection sensors and nozzles of the two sets of oil injection assemblies are installed in a cross-symmetric structure with respect to the left and right sides of the rail. In step S13), when the detection sensor on one side of the rail detects the signal of the sleeper bolt, a control signal is sent to the nozzle on the other side of the rail and at the same transverse horizontal plane as the detection sensor to realize the oil injection operation.

[0026] Furthermore, in step S13), when the detection sensor on the inner side detects the signal of the inner bolt, the outer nozzle is controlled to open. When the detection sensor on the outer side detects the signal of the outer bolt, the inner nozzle is controlled to open.

[0027] Further, the rail-leaning wheel assembly further includes a carriage, a shaft pressing plate, a sleeve, and a sensor mounting plate. The carriage and the sleeve are combined into a mounting frame for the rail-leaning wheel, and the sleeve is sleeved on the lateral guide post. Two rotating shafts are respectively arranged on the front and rear sides of the carriage, and the rail-leaning wheel is movably mounted on the carriage through the shaft pressing plate. The sensor mounting plate is arranged on the front side of the carriage for mounting a height sensor.

[0028] By implementing the technical solution of the sleeper bolt greasing operation method provided by the present invention as described above, the following beneficial effects are achieved:

[0029] (1) For the sleeper bolt greasing operation method of the present invention, a vehicle-mounted operation mode is adopted, which is directly installed at the bottom of the operation vehicle, and power energy and the like are directly provided by means of the vehicle interface. It can realize the greasing operation during continuous running, effectively replace manual operation, improve the operation efficiency, and achieve full integration with the large machine system;

[0030] (2) For the sleeper bolt greasing operation method of the present invention, the structure is flexible and efficient. The flexible guiding mechanism and stretching mechanism that can deflect and reset can enable the rail-leaning greasing mechanism to adapt to the greasing operation under the condition of the superelevation of the line curve, and no additional power and control are required;

[0031] (3) For the sleeper bolt greasing operation method of the present invention, the positioning pin columns designed when the cross beam and the fixed frame cooperate can realize the rapid recovery and positioning of the greasing device during parking operation. The anti-derailment and locking mechanism realizes the rapid operation of the device and the hanging safety in the non-operation state. The rail-leaning driving mechanism and the compression spring combination can realize the rapid and reliable rail-leaning running of the device;

[0032] (4) For the sleeper bolt greasing operation method of the present invention, the sleeper bolt detection sensors and nozzles on the left and right oil spraying mechanisms of the rail-leaning wheel assembly are symmetrically installed in a cross manner relative to both sides of the rail. When a sleeper bolt is detected, the nozzle on the opposite side will perform the oil spraying operation, which not only improves the operation efficiency, but also can prevent the sensor from being polluted by oil splashing, and ensures the real-time performance of the greasing operation.

[0066] As shown in FIGS. Figure 7As shown, the first fixing bracket 33 is welded from metal parts and is an H-shaped integral part that is symmetric about the left and right. It includes longitudinal beams 333 and main cross beams 335. The longitudinal beams 333 are arranged at both ends of the main cross beam 335 along the length direction (such as the direction shown by W in the attachment). One end of the longitudinal beam 333 along the length direction is provided with a positioning hole 334, and the other end is provided with a connecting plate 331. Both ends of the main cross beam 335 along the length direction are provided with mounting holes 332. The first mounting seat 314 is hinged to the mounting hole 332, and one end of the tension spring 322 is fixed to the outer side of the longitudinal beam 333 through the second mounting seat 321. The sleeper bolt greasing device 100 further includes a locking mechanism 5, which is arranged on the first fixing bracket 33 and is used for locking the first fixing bracket 33 and the cross beam 34 in the non-operation mode. One end of the locking mechanism 5 is arranged on the main cross beam 335. Figure 7 As shown in the attachment, the cross beam 34 further includes a main beam 344, and hanging rings 343, positioning pin columns 345 and second hinge seats 342 that are symmetrically arranged on the main beam 344 along the transverse direction (such as the direction shown by W in the attachment). Both ends of the main beam 344 along the transverse direction are provided with first hinge seats 341 connected to the lifting drive mechanism 1. The lower part of the guide post 311 is connected to the main beam 344 through the second hinge seat 342. The hanging ring 343 is used for hanging with the locking mechanism 5 in the non-operation mode. The positioning pin column 345 cooperates with the positioning hole 334 at the lower part of the longitudinal beam 333 to realize the quick positioning of the main beam 344 and the first fixing bracket 33 during the lifting process of the cross beam 34.

[0087] At the lower parts of the left and right ends of the cross beam 34 along the transverse direction, the rail-leaning oiling mechanism 4 is symmetrically installed. The rail-leaning oiling mechanism 4 further includes a second fixing frame 42, a torsion spring 46 and a swing rod 47.

One end of the swing rod 47 is movably installed on the rail-leaning wheel assembly 44 through a rotating shaft 442, and the other end is hinged to the oil injection assembly 43, which is used to realize the swing and reset of the oil injection assembly 43. The oil injection assembly 43 is used for the detection positioning and oiling operation of the sleeper bolt 600. A height sensor 48 for measuring the distance between the rail-leaning oiling mechanism 4 and the rail surface of the rail 300 is installed on the rail-leaning wheel assembly 44. The compression spring 45 is arranged on the transverse guide post 49 and kept between the second fixing frame 42 and the rail-leaning wheel assembly 44 to provide the rail-leaning pressure for the rail-leaning wheel assembly 44. The torsion spring 46 is arranged on the rotating shaft 442 and kept between the rail-leaning wheel assembly 44 and the swing rod 47 to provide a restoring force for the reset of the swing rod 47.

[0088] During the oiling operation in step S13), when the oil injection assembly 43 encounters an obstacle 700 on the line, the link mechanism formed by the swing rod 47 and the oil injection assembly 43 swings back and forth along the line direction (such as the direction shown by L in the attachment Figure 9 to realize obstacle avoidance. After passing through the obstacle 700, the swing rod 47 is reset under the action of the torsion spring 46, as shown in the attachment and the attachment Figure 14 show.

[0089] The oil injection assembly 43 further includes a protective cover 431, a detection sensor 432 and a third mounting seat 434. The third mounting seat 434 is installed inside the protective cover 431, and the nozzle 433 is installed on the third mounting seat 434 and connected to the fuel tank 400.

The detection sensors 432 and nozzles 433 of the two groups of oil injection assemblies 43 are installed in a cross-symmetrical structure with respect to the left and right sides of the rail 300. In step S13), when the detection sensor 432 on one side of the rail detects the sleeper bolt signal, a control signal is sent to the nozzle on the other side of the rail 300 and at the same transverse horizontal plane as the detection sensor 432 according to the sleeper bolt signal to realize the oil injection operation.

[0090] The rail-leaning wheel assembly 44 further includes a carriage 441, an axle pressing plate 443, a sleeve 444, and a sensor mounting plate 445. The carriage 441 and the sleeve 444 are combined to form a mounting frame for the rail-leaning wheel 446, and the sleeve 444 is sleeved on the lateral guide post 49. Two rotating shafts 442 are respectively arranged on the front and rear sides of the carriage 441, and the rail-leaning wheel 446 is movably mounted on the carriage 441 through the axle pressing plate 443. The sensor mounting plate 445 is arranged on the front side of the carriage 441 for mounting the height sensor 48.

When the detection sensor 432 located outside detects the signal of the outer sleeper bolt 600, the inner nozzle 433 is controlled to open.

[0091] As shown in the accompanying drawings, when the sleeper bolt greasing device 100 is operating on a curve, the center of the vehicle frame 200 is offset relative to the center of the rail 300. At this time, the guiding mechanism 31 and the stretching mechanism 32 perform adaptive lateral yaw to ensure that the rail-leaning wheel assembly 44 is always in contact with the rail 300, so as to achieve curve operation.

[0092] As shown in the Figure 17 and accompanying drawings, during the greasing operation, when the railway engineering vehicle enters a curve, the rail-leaning wheel 446 under the sleeper bolt greasing device 100 needs to move left and right to ensure that the front and rear wheels of the railway engineering vehicle and the rail-leaning wheel 446 of the sleeper bolt greasing device 100 adapt to the curve operation of the curve. When the guiding mechanism 31 moves laterally, the inclination sensor 315 installed on the mechanism will detect the deflection angle of the mechanism. First, a mathematical model is established for the lateral offset principle of the sleeper bolt greasing device 100, and then the inclination angle generated by the lateral offset is converted into the bending radius (or chord offset) of the vehicle curve using the three-point detection principle. The mathematical model is converted into a "tilt angle - chord offset / turning radius" curve relationship, and then the real-time detection of the bending radius (or chord offset) of the curve is realized. The mathematical modeling of the lateral offset principle of the sleeper bolt greasing device 100 and the "tilt angle - chord offset / turning radius" curve are shown in the Figure 19 and Figure 18 Figure 19 Figure 20 Figure 21 Figure 22 Figure 23 Figure 24 accompanying drawings. Among them, the curve shown in d is the curve correspondence between the turning radius and the tilt angle, the curve shown in e is the curve correspondence between the chord offset and the tilt angle, and the straight line shown in f is the tilt angle and chord offset values corresponding to the minimum turning radius.

[0093] When the sleeper bolt greasing device 100 is operating on a curve, the lateral displacement (i.e., the chord offset) of the rail-leaning greasing mechanism 4 and the tilt angle are calculated according to the following formula:
