Description

TECHNICAL FIELD

[0001] The present application relates to railway fastener oiling technology, in particular to a rail bolt rust-proof oiling device. BACKGROUND

[0002] With the passage of time of line equipment operation, the fastener bolts on the line sleeper are rusted to varying degrees. The severely rusted nuts are difficult to disassemble even with a wrench, and the long-term unloosened bolts may form a false torque. First, rust will cause the diameter of the bolt to gradually decrease, and stress concentration points will form at the rust pits, significantly reducing the tensile and shear strength. Under the repeated impact of train dynamic load, brittle fracture easily occurs at the rusted parts. Second, the bolt is exposed to a humid environment and comes into contact with rainwater, excrement and acidic substances, forming a micro-battery effect, accelerating metal oxidation, leading to surface loosening, delamination and even fracture. The failure of the fastener system seriously affects the stability of the line, and the rusted nuts are difficult to disassemble and require the use of breaking tools. The rusted bolts need to be anchored and replaced, consuming a large amount of manpower and resources. Third, the track geometry is out of control, and the breakage or loosening of the rusted bolts will directly lead to problems such as track gauge expansion and rail sagging, especially in curved sections or turnout areas, which may cause the train to sway violently or even overturn. Such phenomena have seriously threatened train safety, so periodic oiling operations are carried out every year.

[0003] The patent document with publication number CN114713410A discloses a rail bolt fastener oiling machine and its working method. The oiling machine includes an oil storage device, an oil spraying device, a detection device, a mounting device, a driving device and a control device. The oil storage device is used to store lubricating grease. The oil spraying device is used to uniformly spray the lubricating grease inside the oil storage device onto the surface of the rail bolt fastener. The detection device is used to detect whether the rail bolt fastener is missing and record the position of the missing rail bolt fastener. The mounting device is used to mount the oil storage device, the oil spraying device and the detection device. The driving device is used to provide power to move the mounting device on the rail. The control device is used to control the start and stop of the oil storage device, the oil spraying device, the detection device and the driving device. The present application can realize automatic oiling and detect whether the rail bolt fastener is missing.

DETAILED DESCRIPTION

[0030] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] Please refer to Figures 1-5 A kind of oiling device for preventing rust of rail bolt, including the oiling vehicle body 1 being provided with controller, oiling vehicle body 1 is provided with oil storage box 101 and oil spray head 102, oil storage box 101 is installed with liquid level sensor, the bottom of oiling vehicle body 1 is provided with electric drive wheel 103 for walking on rail.

The above content is all prior art and will not be described here.

[0034] A plurality of accommodating grooves 2 are equidistantly formed on the top of the oiling vehicle body 1, and a spare oil drum is placed in each accommodating groove 2. A guide rail 21 is mounted on the surface of the oiling vehicle body 1, and a moving seat 22 is slidably connected to the guide rail 21. A drive unit is mounted on the moving seat 22, and the drive unit is used to drive the moving seat 22 to move intermittently and linearly on the surface of the guide rail 21. The single movement stroke value of the moving seat 22 is consistent with the distance value between the axes of two adjacent accommodating grooves 2.

[0035] It should be noted that the driving unit drives the moving base 22 to move, and each stop position of the moving base 22 is the position corresponding to the standby oil tank of the hard pipe 214. When the moving base 22 moves to the last position and then moves again, the moving base 22 moves reversely, and the reverse moving position is also the position corresponding to the standby oil tank.

[0036] The lifting frame 23 is installed on the top of the moving base 22, the horizontal plate 24 is installed on the lifting frame 23, the hard pipe 214 is installed on the bottom of the horizontal plate 24, the electric telescopic rod 25 is installed on the surface of the lifting frame 23, the pressure sensor 26 is installed on the surface of the hard pipe 214, the protection box is installed on the oiling vehicle body 1, the delivery pump 27 is installed in the protection box, and the pump suction pipe 28 and the pump delivery pipe 29 are connected to the delivery pump 27.

[0037] It should be noted that the lifting frame 23 is provided with the guide vertical groove 210, the end of the horizontal plate 24 is in sliding connection with the inner side of the guide vertical groove 210, and the two sides of the inner wall of the guide vertical groove 210 are symmetrically provided with the matching vertical grooves 211, the matching blocks 212 matched with the matching vertical grooves 211 are installed on the horizontal plate 24, the end of the horizontal plate 24 penetrates through the guide vertical groove 210 and is provided with the connecting block 213, and the bottom of the telescopic end of the electric telescopic rod 25 is fixedly connected with the connecting block 213.

[0038] Through the cooperation between the matching vertical grooves 211 and the matching blocks 212, the horizontal plate 24 can move vertically stably under the drive of the electric telescopic rod 25, so that the poor balance of the horizontal plate 24 caused by the arrangement of the hard pipe 214 and the like when the horizontal plate 24 moves vertically can be effectively reduced.

[0039] In addition, the hard pipe 214 is externally provided with the cover 3 corresponding to the top opening of the standby oil tank, so that the grease in the standby oil tank can be effectively protected, and the situation that impurity particles are mixed into the grease to cause the clogging of the grease nozzle 102 can be avoided.

[0040] Further, the pump suction end of the pump suction pipe 28 is fixedly communicated with the top end of the hard pipe 214, and the pump delivery end of the pump delivery pipe 29 is fixedly communicated with the inside of the oil storage box 101.

[0041] In the embodiment, the driving unit includes the driving motor 4 installed in the protection box, the driving shaft end of the driving motor 4 is provided with the driving screw 41, and the moving base 22 is in threaded connection with the driving screw 41.

[0042] In addition, the protection box is internally provided with the buzzer 5, through the arrangement of the buzzer 5, the operator can be prompted when the grease in one standby oil tank is pumped out and the next standby oil tank needs to be pumped, so that the operator can open the cover on the standby oil tank to be used.

[0043] In this embodiment, the pressure sensor 26, the delivery pump 27, the driving motor 4, the electric telescopic rod 25, the buzzer 5 and the liquid level sensor are electrically connected with the controller.

[0044] It should be noted that the liquid level sensor arranged in the oil storage box 101 monitors the height of the oil position in the oil storage box 101 in real time, and transmits the detected data signal to the controller. When the amount of oil inside is small, the controller controls the delivery pump 27 to pump the oil in the standby oil tank into the oil storage box 101, so as to automatically supplement the oil;

[0045] The pressure sensor 26 arranged at the bottom end of the side of the hard pipe 214 can monitor the amount of oil in the standby oil tank in real time, and transmit the detected data signal to the controller. When the amount of oil in the standby oil tank is used up, the controller controls the buzzer 5 to emit a buzzing sound to prompt the operator, so that the operator can take off the cover on the standby oil tank to be used. Then, the controller controls the electric telescopic rod 25 to drive the horizontal plate 24 to move upward and drive the hard pipe 214 to exit from the current standby oil tank. Then, the driving motor 4 drives the driving screw 41 to rotate, so that the moving seat 22 moves once, so that it can move the hard pipe 214 to the standby oil tank to be used. Then, the telescopic end of the electric telescopic rod 25 is extended again and drives the hard pipe 214 to move downward and immerse in the standby oil tank.

[0046] Embodiment 2:

[0047] Please refer to Figures 6-7 , the embodiment provides a technical scheme on the basis of the above-mentioned embodiment: the side of the oiling vehicle body 1 is rotationally connected with a protective plate 6, and a plurality of rotating rods 61 are equidistantly arranged on the side of the protective plate 6 close to the standby oil tank.

[0048] It should be noted that the rotating rod 61 can be a conventional non-powered rotating rod 61, or can be selected according to the need to be driven by electricity. When the standby oil tank is transported, the protective plate 6 can be lowered so that one end thereof is in contact with the ground. At this time, the operator can directly push the standby oil tank onto the protective plate 6, so that the transportation of the standby oil tank is more convenient under the assistance of the rotating rod 61, and a standby oil tank with a larger oil storage capacity can be selected, so that the single oiling work load of the oiling trolley can be significantly improved.

[0049] In addition, the side of the protective plate 6 is rotationally connected with a U-shaped rod 62, and a hanging rod 63 corresponding to the U-shaped rod 62 is mounted on the surface of the protective box. In the non-feeding state, the protective plate 6 is rotated upward, and the U-shaped rod 62 is clamped on the hanging rod 63, so that the protective plate 6 can always remain in a vertical state, thereby playing a certain protective role on the standby oil tank during the oiling work.

[0050] The foregoing merely illustrates some exemplary embodiments of the application, and it will be appreciated that those skilled in the art will be able to devise various modifications without departing from the spirit and scope of the application. The appended drawings and description are illustrative only, and are not intended to be limiting.
