Description

Technical Field

[0001] The present invention relates to the technical field of railway engineering machinery, and in particular to an on-board oiling operation device used for performing oiling maintenance operations on rail bolts on a large-scale comprehensive maintenance train, and a railway engineering operation vehicle comprising the device. Background Art

[0002] With the increase in railway speeds and heavier loads, the demands on railway lines are constantly increasing. Therefore, modern railway construction and maintenance operations utilize a large number of large, highly automated machines, such as bridge erectors, track laying machines, tamping machines, screening machines, rail grinding machines, and trackbed shaping machines. Currently, the mechanization and automation of major railway line construction and maintenance operations are highly advanced, and the quality of work has reached a high level. However, some non-critical maintenance tasks, such as sleeper bolt maintenance, are still largely performed manually. This method is not only labor-intensive and inefficient, but also prone to many uncontrolled human factors, resulting in low maintenance quality. With the current trend of high-speed and high-density railway lines, effective maintenance is crucial to ensuring the safety and stability of line equipment. To prevent rust on the rail studs, rail bolts must be regularly lubricated. This lubrication not only ensures proper function and prevents corrosion, but also facilitates routine loosening and tightening, maintains track geometry and track frame rigidity, extends equipment life, and ensures safe and stable train operation. Currently, lubricating fasteners is typically done during the railway's window period. This involves individuals carrying small mops or brushes to lubricate the fasteners. A separate person is required to pull a flatbed truck carrying oil drums, and then another person lubricates the fasteners on both sides of the track using a mop or brush. Due to the length of the railway line, this lubrication method wastes significant labor, is inefficient, and lacks quality assurance and standards. It also makes it difficult to quickly lubricate fasteners along the entire length of the track. While some semi-manual lubrication systems employ small, hand-operated bolt lubricating equipment, while saving some labor, most lack the ability to accurately detect and locate fasteners, requiring manual adjustment. Furthermore, this one-person-per-truck approach to lubrication does not significantly improve efficiency. Furthermore, the coordinated operation does not avoid the window period, making it difficult to integrate with other large-scale equipment maintenance operations.

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

[0004] 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 publication number CN107227664A. This invention discloses a trolley for automatically tightening and lubricating railway track bolts, comprising a traveling device, a frame mounted on the traveling device, a bolt detection sensor, a bolt tightening device, and a bolt lubricating device mounted on the frame. The bolt tightening device comprises a supporting platform, a lead screw vertical motion mechanism mounted on the supporting platform, the supporting platform being threadedly connected to the lead screw of the lead screw vertical motion mechanism, at least one set of XY adjustment platforms movably connected to the supporting platform, and a bolt tightening machine connected to the lower end of the adjustment platform. The bolt tightening machine comprises, arranged in order from top to bottom, a bolt tightening drive motor, a torque controller, and a bolt centering guide sleeve. Compared to existing bolt tightening devices, this trolley has a high degree of automation, saves manpower, and improves the efficiency of railway maintenance. However, the invention requires two sets of devices, namely a bolt tightening device and a bolt oiling device, to complete the automatic tightening and oiling operations of the rail bolts, resulting in a complex overall structure and poor economy, and further improvement is still needed.

[0005] 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 publication number CN 107299565A. This invention discloses a railway track maintenance machine based on a collaborative working mode of a master and slave machine, comprising a host machine, a master machine, and a slave machine. The master machine is equipped with an unevenness detection module, a defect detection module, and a bolt loosening detection module, while the slave machine is equipped with a bolt tightening device, an oiling device, a grinder, and a backtesting device. The unevenness detection module and the defect detection module are respectively connected to the host machine, which is used to control the bolt tightening device, the oiling device, the grinder, and the backtesting device. Although the maintenance machine is small in size, it has a high degree of integration, automation, and intelligence, and is highly efficient. While saving manpower, it changes the traditional working mode of separating inspection and maintenance, realizes the collaborative operation of inspection and maintenance in daily railway maintenance, reduces the cost required for daily maintenance, and improves maintenance work efficiency. However, the invention requires two sets of devices, namely a bolt tightening device and an oiling device, to complete the automatic tightening and oiling operations of the rail bolts, resulting in a complex overall structure and poor economy, and further improvement is still needed.

[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.

One end of the rocker arm 47 is movably mounted on the rail wheel assembly 44 through the rotating shaft 442, and the other end is hinged to the oil injection assembly 43 to realize the swing and reset of the oil injection assembly 43. The oil injection assembly 43 is used for detecting, positioning and lubricating the sleeper bolts 600. A height sensor 48 for measuring the distance between the rail-resting oiling mechanism 4 and the rail surface of the rail 300 is installed on the rail wheel assembly 44. The compression spring 45 is arranged on the transverse guide column 49 and is located between the second fixed frame 42 and the rail wheel assembly 44 to provide rail-restoring pressure for the rail wheel assembly 44. The torsion spring 46 is arranged on the rotating shaft 442 and is located between the rail wheel assembly 44 and the rocker arm 47 to provide a restoring force for the reset of the rocker arm 47.

The nozzle 433 is directly connected to the fuel tank 400 via an oil pipe and is used to apply oil to the sleeper bolts 600. The detection sensor 432 is installed inside the protective cover 431 by screws for detecting the sleeper bolts 600. The protective cover 431 is provided with two ear holes, which are hinged to the end of the rocker 47 of the rail wheel assembly 44 to protect the detection sensor 432 and the nozzle 433 from collision when the railway engineering work vehicle is running.

[0063] As attached Figure 14As shown, the rail wheel assembly 44 further includes a slide 441, an axle pressure plate 443, a sleeve 444, a sensor mounting plate 445 and a rail wheel 446. The slide 441 and the sleeve 444 constitute the mounting frame of the rail wheel 446, and the sleeve 444 is sleeved on the transverse guide column 49. Two rotating shafts 442 are respectively provided on the front and rear sides of the slide 441, and the rail wheel 446 is movably mounted on the slide 441 through the axle pressure plate 443. The sensor mounting plate 445 is provided on the front side of the slide 441 for installing the height sensor 48, and the height sensor 48 is used to provide signal feedback when the rail wheel 446 is lowered into place. The rail drive mechanism 41 provides the pre-pressure of the compression spring 45, so that the rail wheel 446 can move along the attached Figure 14 The direction indicated by W in the middle is accurately aligned with the track.

[0064] As attached Figure 15 As shown, the locking mechanism 5 further includes a fourth mounting seat 51, a fifth mounting seat 52, a locking drive mechanism 53, and a hook 54. The hook 54 is hingedly connected to the fifth mounting seat 52 and mounted to the bottom of the main beam 335 via the fifth mounting seat 52. One end of the locking drive mechanism 53 is hingedly connected to the fourth mounting seat 51 and mounted to the front or rear side of the main beam 335 via the fourth mounting seat 51. The other end is hingedly connected to the hook 54. The locking drive mechanism 53 is extended and retracted to lock and unlock the beam 34. The two locking mechanisms 5 are mounted in a bilaterally symmetrical structure on the front and rear sides of the beam 34 (or can be mounted on the same side). The locking and unlocking of the beam 34 is achieved by the extension and retraction of the locking drive mechanism 53. The fourth mounting seat 51 is bolted to the front or rear of the beam 34 of the first fixing frame 33 and is used to mount the locking drive mechanism 53. The fifth mounting seat 52 is bolted to the lower portion of the beam 34 of the first fixing frame 33 and is used to mount the hook 54. The cylinder of the locking drive mechanism 53 is hingedly mounted on the fourth mounting seat 51, and the front portion of the push rod is hingedly connected to the hook 54 via a pin, and the hook 54 is rotated by telescoping. The hook 54 is connected to the fifth mounting seat 52 via a pin and is locked with the hook ring 343 on the crossbeam 34 in the locked state.

[0065] In this embodiment, the power unit, including the lifting drive mechanism 1, the rail-resting drive mechanism 41, and the locking drive mechanism 53, can be a linear actuator such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The type of height sensor 48 and detection sensor 432 can be flexibly selected. Within the same structural form, laser, inductive, proximity switch, and other types can be selected. The tension spring 322 is used to limit the deflection and reset the guide mechanism 31. Rubber or other elastic elements can also perform this function. The crossbeam 34 and the first fixing bracket 33 are connected by positioning holes 334 in the lower portion of the longitudinal beam 333 and positioning pins 345 on the crossbeam 34. A similar function can also be achieved by opening holes in the crossbeam 34. In this embodiment, the rail-resting mechanism and the oil injection assembly can both operate independently on the sleeper bolts 600 on the same sleeper 500. Schemes employing similar structures and operating methods, but with only an increase in the number of rail-resting wheels or nozzles, fall within the scope of the present invention.

[0066] The vehicle-mounted sleeper bolt oiling device provided in Example 1 is used for large-scale comprehensive maintenance trains to perform oiling and maintenance operations on rail bolts. It adopts an automated operation method that is compatible with the large machine system. It can solve the technical problems of manpower waste, low efficiency, and incompatibility with the large line maintenance machine system caused by manual or semi-manual window period oiling operations in the existing technology. While reducing the labor intensity of the sleeper bolt oiling operation, it reduces labor costs and improves the efficiency of the oiling operation.

The sleeper bolt oiling device 100 and the oil tank 400 travel with the railway engineering work vehicle, and the oil tank 400 is connected to the sleeper bolt oiling device 100 via an oil pipe 800.

[0069] Example 3

[0070] An embodiment of a method for lubricating sleeper bolts of a railway engineering work vehicle based on the second embodiment specifically comprises the following steps:

[0071] S10) After the railway engineering work vehicle arrives at the work site, before the oiling operation is carried out, the locking mechanism 5 is first opened;

[0072] S11) The lifting drive mechanisms 1 on the left and right sides extend synchronously, driving the main frame 3 to lower the rail oiling mechanism 4, as shown in the attached figure. Figure 16 As shown;

[0073] S12) When the rail wheel assembly 44 of the rail lubricating mechanism 4 contacts the rail 300, the rail driving mechanism 41 releases pressure, and the rail wheel assembly 44 moves along the rail under the action of the compression spring 45. Figure 9 and attached Figure 14 The wheel flange of the rail wheel 446 of the rail wheel assembly 44 is in contact with the inner side of the rail 300 to complete the rail leaning action. Figure 17 As shown;

[0074] S13) The oil spraying assembly 43 of the rail oiling mechanism 4 detects the signal of opening the sleeper bolt 600 and controls the nozzle 433;

[0075] S14) After the oiling operation is completed, the rail driving mechanism 41 is stretched, driving the rail wheel 446 to separate from the inner side of the rail 300. The lifting driving mechanism 1 drives the rail oiling mechanism 4 to rise. The rail driving mechanism 41 releases pressure, and the rail wheel assembly 44 moves under the action of the compression spring 45, locking the locking mechanism 5 and the main frame 3.

[0076] The upper end of the anti-slip chain 2 is connected to the vehicle frame 200, and the lower end is connected to the crossbeam 34 via the anti-slip interface 346 when not in operation. This prevents the rail lubrication mechanism 4 from falling off and dropping. In step S10), before lubricating, the anti-slip chains 2 on both sides of the vehicle frame 200 are first released, and then the locking mechanism 5 is opened. After the lubrication is completed, in step S14, the locking mechanism 5 is first locked to the main frame 3, and then the anti-slip chain 2 is connected to the crossbeam 34.

[0077] The main frame 3 includes a first fixed frame 33 and a crossbeam 34. The first fixed frame 33 is mounted on the bottom of the vehicle frame 200. The upper portion of the lifting drive mechanism 1 is connected to the vehicle frame 200, and the lower portion is connected to the crossbeam 34. Driven by the lifting drive mechanism 1, the crossbeam 34 moves up and down relative to the first fixed frame 33. Rail lubrication mechanisms 4 are mounted on the left and right sides of the crossbeam 34 to facilitate rail lubrication and lubrication of the sleeper bolts 600. A locking mechanism 5 is provided on the crossbeam 34 to lock the first fixed frame 33 and crossbeam 34 in the non-operating mode.

[0078] The main frame 3 also includes a guide mechanism 31 and a tensioning mechanism 32. The guide mechanism 31 is hinged to the first fixed frame 33 and the crossbeam 34, respectively, and the tensioning mechanism 32 is connected between the first fixed frame 33 and the guide mechanism 31. The upper portion of the lifting drive mechanism 1 is hinged to the vehicle frame 200, and the lower portion is hinged to the crossbeam 34. The guide mechanism 31 is used to guide the crossbeam 34 during lifting, support it during lateral movement, and traction during travel. The guide mechanism 31 includes a guide post 311, a protective cover 312, a guide sleeve 313, and a first mounting seat 314. An inclination sensor 315 is mounted on the first mounting seat 314. The protective cover 312 is mounted on the exterior of the guide post 311, and the guide sleeve 313 is mounted on the protective cover 312. The first mounting seat 314 is fixed to the outer portion of the guide sleeve 313. The lower portion of the guide post 311 is hinged to the crossbeam 34, and the first mounting seat 314 is hinged to the first fixed frame 33. The tensioning mechanism 32 includes a second mounting seat 321, a tension spring 322, and a pin 323. The tension spring 322 is connected to the second mounting seat 321 at both ends along its length via the pin 323. One end of the tension spring 322 is secured to the first mounting seat 314 via the second mounting seat 321, and the other end is secured to the first fixing bracket 33 via another second mounting seat 321. This serves to limit and reset the guide mechanism 31 when it deflects.

[0079] The first fixing frame 33 includes a longitudinal beam 333 and a main crossbeam 335. The longitudinal beam 333 is arranged at both ends of the main crossbeam 335 along its length. A positioning hole 334 is provided at one end of the longitudinal beam 333, and a connecting plate 331 is provided at the other end. Mounting holes 332 are provided at both ends of the main crossbeam 335 along its length. The first mounting seat 314 is hinged to the mounting hole 332, one end of the tension spring 322 is fixed to the outer side of the longitudinal beam 333 via the second mounting seat 321, and one end of the locking mechanism 5 is mounted on the main crossbeam 335. The crossbeam 34 includes a main beam 344, as well as a hanging ring 343, a positioning pin 345, and a second hinge seat 342, which are arranged symmetrically on the main beam 344 in the transverse direction. First hinge seats 341 connected to the lifting drive mechanism 1 are provided at both ends of the main beam 344 in the transverse direction. The lower portion of the guide post 311 is connected to the main beam 344 via the second hinge seat 342. The hanging ring 343 is used to connect to the locking mechanism 5 in the non-operating mode. The positioning pin 345 is engaged with the positioning hole 334 at the lower portion of the longitudinal beam 333 to achieve rapid positioning of the main beam 344 and the first fixing frame 33 during the raising process of the crossbeam 34.

[0080] A rail lubricating mechanism 4 is symmetrically mounted on the lower left and right ends of the crossbeam 34 along the transverse direction. The mechanism 4 also includes a second fixing frame 42, a torsion spring 46, and a rocker arm 47. The second fixing frame 42 is mounted below the crossbeam 34, and a transverse guide post 49 is provided on the second fixing frame 42. The rail wheel assembly 44 is movably mounted on the transverse guide post 49. A rail driving mechanism 41 is positioned between the second fixing frame 42 and the rail wheel assembly 44. The rail driving mechanism 41 drives the rail wheel assembly 44 along the transverse guide post 49 to achieve rail alignment. One end of the rocker arm 47 is movably mounted on the rail wheel assembly 44 via a rotating shaft 442. The other end is hingedly connected to the oil spray assembly 43 to enable the oil spray assembly 43 to swing and reset. The oil spray assembly 43 is used for detecting, positioning, and lubricating the sleeper bolts 600. A height sensor 48 is mounted on the rail wheel assembly 44 to measure the distance between the rail lubricating mechanism 4 and the surface of the rail 300. A compression spring 45 is mounted on a transverse guide post 49 and held between the second fixing bracket 42 and the rail wheel assembly 44, providing pressure to the rail wheel assembly 44. A torsion spring 46 is mounted on a rotating shaft 442 and held between the rail wheel assembly 44 and the rocker arm 47, providing a restoring force to reset the rocker arm 47.

[0081] During the oiling operation in step S13), when the oil spraying assembly 43 encounters an obstacle 700 on the line, the connecting rod mechanism formed by the rocker 47 and the oil spraying assembly 43 moves in the line direction (such as the attached Figure 19 After passing the obstacle 700, the swing rod 47 is reset under the action of the torsion spring 46, as shown in the attached figure. Figure 18 and attached Figure 19 shown.

[0082] The oil injection assembly 43 also 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 oil tank 400. The detection sensor 432 is installed inside the protective cover 431 for detecting and positioning the sleeper bolts 600. Two groups of oil injection assemblies 43 are symmetrically arranged on the left and right sides of the rail wheel assembly 44. The detection sensors 432 and nozzles 433 of the two groups of oil injection assemblies 43 are installed in a cross-symmetrical structure relative to the left and right sides of the rail 300. In step S13), when the detection sensor 432 located on one side of the rail detects the sleeper bolt signal, a control signal is sent to the nozzle located on the other side of the rail 300 and in the same horizontal plane as the detection sensor 432 according to the sleeper bolt signal to realize the oil injection operation.

[0083] The rail wheel assembly 44 also includes a slide 441, an axle pressure plate 443, a sleeve 444 and a sensor mounting plate 445. The slide 441 and the sleeve 444 are combined into a mounting frame for the rail wheel 446, and the sleeve 444 is sleeved on the transverse guide column 49. Two rotating shafts 442 are respectively set on the front and rear sides of the slide 441, and the rail wheel 446 is movably mounted on the slide 441 through the axle pressure plate 443. The sensor mounting plate 445 is set on the front side of the slide 441 for mounting the height sensor 48. In step S13), when the detection sensor 432 located on the inside detects the signal of the inner sleeper bolt 600, the outer nozzle 433 is controlled to open. When the detection sensor 432 located on the outside detects the signal of the outer sleeper bolt 600, the inner nozzle 433 is controlled to open.

[0084] As attached Figure 20 As shown, when the sleeper bolt oiling device 100 is operating in a curve, the center of the frame 200 is offset relative to the center of the rail 300. At this time, adaptive lateral deflection is performed through the guide mechanism 31 and the stretching mechanism 32 to ensure that the rail wheel assembly 44 is always in contact with the rail 300 to achieve curve operation.

[0085] As attached Figure 21 and attached Figure 22 As shown, during the oiling operation, when the railway engineering work vehicle enters a curve, the rail-supporting wheels 446 below the sleeper bolt oiling device 100 need to move horizontally to ensure that the front and rear wheels of the railway engineering work vehicle and the rail-supporting wheels 446 of the sleeper bolt oiling device 100 adapt to the curve driving operation. When the guide mechanism 31 moves horizontally, the inclination sensor 315 installed on the mechanism will detect the deflection angle of the mechanism. First, the lateral offset principle of the sleeper bolt oiling device 100 is mathematically modeled, and then the inclination angle generated by the lateral offset is converted into the bending radius (or vector distance) of the vehicle curve using the three-point detection principle. The mathematical model is converted into a "inclination angle-vector distance / turning radius" curve relationship, thereby realizing real-time detection of the bending radius (or vector distance) of the curve. The mathematical modeling of the lateral displacement principle of the sleeper bolt oiling device 100 and the "inclination angle-vector distance / turning radius" curve are shown in the attached figure. Figure 23 and attached Figure 24 Among them, the curve shown in d is the corresponding relationship between the turning radius and the inclination angle, the curve shown in e is the corresponding relationship between the sag and the inclination angle, and the straight line shown in f is the corresponding inclination angle and sag value at the minimum turning radius.

[0086] When the sleeper bolt oiling device 100 is operating in a curve, the lateral displacement of the rail oiling mechanism 4 is (i.e., sagittal distance) and inclination The relationship is calculated according to the following formula:
