Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of railway engineering machinery, and particularly relates to a device for track bolt oiling operation applied to a vehicle and a track engineering vehicle. BACKGROUND

[0002] With the development of track traffic construction, railway speed-up and heavy load, the workload of track maintenance is increasing, and the requirement for maintenance quality is also increasing. As an important part of railway maintenance work, track sleeper bolts need to be regularly oiled and rust-proof. At present, the oiling operation of railway fasteners usually adopts manual operation or uses some small hand-push bolt oiling equipment for semi-manual operation, and the operation efficiency is low, and the oiling operation quality cannot be kept stable.

[0003] The prior art usually adopts a hydraulic electromagnetic valve to directly control the start and stop of spraying medium, and due to the performance limitation of the hydraulic electromagnetic valve, the automatic oiling operation can only use rust-proof oil with low viscosity and low flowability, and cannot be applied to the spraying of high-viscosity rust-proof grease. Therefore, most of the existing automatic oiling equipment can only be applied to the spraying of rust-proof oil, and the spraying of rust-proof grease has better rust-proof effect in actual oiling operation. In addition, the existing spraying method cannot perform high-frequency on-off control on the atomized spraying of rust-proof grease, and most of the existing spraying methods vertically downwardly spray the bolt (or fastener) of the sleeper through a nozzle, and cannot effectively spray the bolt cylindrical surface in all directions.

[0004] In the prior art, the following documents are mainly related to the present application:

[0005] Prior art 1 is a Chinese invention application with the application date of September 24, 2021 and the publication date of December 10, 2021, the publication number of CN113769920A. The application discloses a rail tie bolt automatic oil spraying device and a spraying oil method. The automatic oil spraying device is installed on the lifting and shifting device of the tamping car, and contains a mounting bracket, a lead screw, a motor, a limiting block, a bolt detection sensor, an oil circuit and an air circuit, etc. The mounting bracket is installed on the lifting and shifting device of the tamping car. The mounting bottom plate is fixedly installed on the mounting bracket, the mounting bracket is provided with a cavity, the lead screw is rotatably installed in the cavity, the motor is installed at one end of the mounting bracket and connected with the lead screw. The sliding block is arranged in the cavity and threadedly connected with the lead screw, and the limiting piece is arranged on one side of the mounting bottom plate and connected with the sliding block. The limiting piece has a downward mounting column, and the third proximity switch and the oil nozzle are installed on the mounting column. The oil circuit and air circuit system are connected with the oil nozzle. The control system is connected with the first proximity switch, the second proximity switch, the third proximity switch and the oil circuit and air circuit system. The device is used for step-by-step operation, and the vehicle needs to be in a stopped state during operation. The motor drives the lead screw to drive the bolt detection sensor and the nozzle to position the bolt, and then the oil spraying is realized through the oil circuit and the air circuit. The oil circuit of the automatic oil spraying device of the application does not have a supercharging device, and the oil is atomized and sprayed by compressed gas, which has poor spraying effect and low operation quality.

[0006] Prior art 2 is a Chinese invention application with the application date of July 11, 2022 and the publication date of October 18, 2022, the publication number of CN115198582A.

The main frame includes a first fixed frame and a cross beam, and the first fixed frame is installed on the bottom of the vehicle frame. The upper part of the lifting driving mechanism is connected with the vehicle frame, and the lower part is connected with the cross beam. The cross beam can move up and down relative to the first fixed frame under the driving of the lifting driving mechanism. The rail following oiling mechanism is installed on the left and right sides of the cross beam, and is used to realize the rail following operation and the oiling operation of the bolt. When the rail tie bolt signal is detected, the rail following oiling mechanism performs the oiling operation on the rail tie bolt. The application mainly solves the technical problem of the oiling device in the middle part of the vehicle on the curve section, but the structure of the oiling device is relatively complex.

The device uses compressed air to pressurize the oil in the oil tank, and uses air-assisted spraying. However, this spraying device is only suitable for rust-proof oil spraying and cannot perform high-frequency on-off control for atomizing and spraying rust-proof grease. Utility model content

DETAILED DESCRIPTION

[0054] To make the purpose, technical solutions, and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the application.

[0055] As shown in the accompanying Figure 1 toFigure 18 The specific embodiments of the rail bolt oiling operation device and the rail engineering vehicle of the present application are shown in the drawings, and the present application will be further described below in conjunction with the drawings and specific embodiments.

[0056] The following specific embodiments take the rail replacement vehicle as an example to describe the technical solutions of the present application. The rail bolt oiling operation device described in the specific embodiments of the present application can be applied to large and medium-sized rail engineering vehicles, and can also be applied to small rail trolleys for oiling operation.

[0057] Embodiment 1

[0058] As shown in the drawings, Figure 1 to the drawings, Figure 7 As shown in the drawings, an embodiment of the rail bolt oiling operation device of the present application, the oiling operation device 10 runs on the rail 6 with the rail engineering vehicle 100, and specifically includes: a detection execution mechanism 1, a grease tank 2, a pressurizing device 3, and a control system 4. The installation positions of the components are shown in the drawings. Figure 1 The detection execution mechanism 1 further includes a sleeper bolt detection sensor 104 and a spray gun 105. The detection execution mechanism 1 is installed on the end beam 15 of the bogie 5 close to the wheel 9. The sleeper bolt detection sensor 104 is installed at the lowermost part of the detection execution mechanism 1. Its main function is to detect the position of the railway rail spike (i.e. the sleeper bolt 8) and transmit a detection signal to the control system 4. The grease in the grease tank 2 is communicated with the oil circuit 13 of the spray gun 105 through the pressurizing device 3. When the oiling operation is performed, the compressed air of the vehicle is used as the power to pressurize the grease tank 2 to the required pressure. When the sleeper bolt detection sensor 104 (passes above the sleeper bolt 8) detects the sleeper bolt 8, a signal is sent to the control system 4. The control system 4 determines the delay time according to the collected vehicle speed, and outputs a signal through the electromagnetic valve 11 to control the air circuit 12 to open after a delay. The high-pressure grease is sprayed onto the target sleeper bolt 8 of the sleeper 7 through the spray gun 105.

[0059] The embodiment adopts a pneumatic automatic spray gun control mode. The electromagnetic valve 11 of the air circuit 12 controls the opening and closing of the spray gun 105, which can be applied to the atomizing oiling operation of the special rust-proof and corrosion-proof grease for railway sleeper bolts. Meanwhile, it can also realize higher frequency control, so that the oiling operation efficiency of the oiling operation device 10 is greatly improved. The oiling operation device 10 described in Embodiment 1 has a simple structure, can be applied to automatic oiling operation of high-viscosity rust-proof grease, and has the advantages of fast operation speed and good oiling effect.

[0060] As shown in the drawings, Figure 8 to the drawings, Figure 10 As shown in the drawings, the detection execution mechanism 1 has the functions of lifting, locking, spike detection, spraying, and sensor obstacle avoidance, and further includes:

[0061] Mounting bracket 101; Mounting bracket 101 is the main mounting body of the detection actuator 1. All other components of the detection actuator 1 are connected to the vehicle body through mounting bracket 101; Mounting bracket 101 is mounted on mounting plate 110 of end beam 15 by bolts. Shock-absorbing pads 111 are also fitted on the bolts between mounting bracket 101 and mounting plate 110.

[0062] The upper fixing plate 123 and the lower fixing plate 124 are provided on the mounting bracket 101;

[0063] The guide rod 107 is disposed between the upper fixed plate 123 and the lower fixed plate 124; the guide rod 107 is fixed on the mounting bracket 101, the two guide rods 107 are arranged in parallel, and the guide rod 107 provides guidance for the lifting and lowering movement of the other components of the actuator;

[0064] A lifting frame 103 is movably mounted on the guide rod 107; a sliding sleeve may also be mounted on the lifting frame 103, and the sliding sleeve and the guide rod 107 form a kinematic cooperation relationship to realize the lifting action;

[0065] A lifting cylinder 102, with one end fixed to the mounting bracket 101 and the other end fixed to the lifting frame 103, provides power for the lifting movement of the detection actuator 1.

[0066] Sleeper bolt detection sensor 104 is installed at the bottom front end of the lifting frame 103;

[0067] Located at the bottom of the lifting frame 103, and along the horizontal direction (as shown in the attached diagram). Figure 9 The spray guns 105, arranged opposite each other in pairs (as shown in direction A), are positioned longitudinally (as shown in the attached diagram). Figure 10 The spray guns 105, arranged symmetrically at an angle (as shown in direction B), spray the same sleeper bolt 8. To achieve a good coating effect on the surface of the sleeper bolt 8, two spray guns 105 are arranged symmetrically at an angle along the working direction to perform cross-spraying on the same sleeper bolt 8. As a typical specific embodiment of this utility model, one detection actuator 1 is equipped with four spray guns 105, and a total of eight spray guns 105 are equipped for the detection actuators 1 corresponding to the two sides of the track 6. The high-pressure oil pipes of the four (automatic) spray guns 105 of the same detection actuator 1 can be connected in series. In addition, oil supply to the four spray guns 105 can also be achieved by using a parallel connection through pipeline installation changes. However, compared with parallel oil supply, the series oil supply method significantly reduces the amount of oil pipe used. The method of spraying the same sleeper bolt with two spray guns 105 arranged symmetrically at an angle in this embodiment has a better coating effect than the prior art of using one nozzle to spray the sleeper bolt 8 vertically.

[0068] The guide rod 107 is provided with a limiting ring 109, which can move up and down along the length direction of the guide rod 107 and is fixed at different height positions on the guide rod 107 to limit the descending height of the lifting frame 103, so that the rail tie bolt detection sensor 104 and the spray gun 105 are in a set height range, thereby meeting the operation requirements under different height rail conditions.

[0069] The guide rod 107 is further provided with an adjusting spring 108, which is located above the limiting ring 109. When the oiling operation is performed, the lifting frame 103 is lowered, and the downward pressure provided by the lifting cylinder 102 compresses the adjusting spring 108. The extension and contraction of the adjusting spring 108 are realized by controlling the presence or absence of the downward pressure of the lifting cylinder 102, and the height of the lifting frame 103 is further fine-tuned to meet the oiling operation requirements.

[0070] As shown in the accompanying drawings, Figure 11 The detection execution mechanism 1 further includes a locking mechanism, an upward position detection sensor 112 and a locking position detection sensor 113. The locking mechanism further includes a locking cylinder 106, a retreat prevention spring 118 and a locking pin 119. The upward position detection sensor 112 and the locking position detection sensor 113 are both arranged on an upper fixed plate 123, the fixed end of the locking cylinder 106 is installed on the upper fixed plate 123, and the outer part of the movable end is sleeved with the retreat prevention spring 118 and connected with the locking pin 119. The function of the upward position detection sensor 112 is to detect whether the lifting frame 103 is in the upward position. Only after the upward position detection sensor 112 detects that the lifting frame 103 is in the upward position, the locking action can be performed, otherwise the locking action cannot be triggered, and the control system 4 will display a fault and alarm. The locking cylinder 106 provides power for the locking action, drives the locking pin 119 to move, and realizes the locking and unlocking functions. When the detection execution mechanism 1 is in a non-working state, under the action of the lifting cylinder 102, the detection execution mechanism 1 is lifted to the position of the traveling state, and the locking mechanism can lock the moving parts to ensure that they remain stationary at the position of the traveling state, thereby ensuring the traveling safety. The locking cylinder 106 drives the locking pin 119 to realize the locking between the locking part 125 at the upper part of the lifting frame 103 and the upper fixed plate 123. As shown in the accompanying drawings, Figure 12As shown, the lifting frame 103 is provided with a gas distribution block 114 for distributing the gas source controlled by the electromagnetic valve group to different spray guns 105 to provide power source for the opening and closing of the spray guns 105. The retreat prevention spring 118 can lock the locking pin 119 in the locked state when the locking cylinder 106 is cut off the gas source, so as to ensure the locking reliability. The control system 4 considers that the locking cylinder 106 is locked in place only when the locking-in-place detection sensor 113 detects the signal of the locking pin 119, otherwise a fault alarm will be given. When the detection execution mechanism 1 is in the working state, the locking cylinder 106 pushes the locking pin 119 to unlock, and under the action of the lifting cylinder 102, the detection execution mechanism 1 is lowered to the working position.

[0071] When the track engineering vehicle 100 is in the oiling operation, the sleeper bolt detection sensor 104 is below the rail surface of the track 6 and is close to the sleeper bolt 8. When there is an error in the height of the sleeper bolt 8 or there is a foreign matter on the line, the sleeper bolt detection sensor 104 will collide with the obstacle and be damaged. As shown in FIG. 6, the detection execution mechanism 1 further comprises an obstacle avoidance mechanism, which further comprises a spring mounting plate 115, a reset spring 116, a rotating pin shaft 117, a plunger 120 and a guide pin shaft 121. The obstacle avoidance mechanism is a mechanism that can swing to pass through the obstacle when the sleeper bolt detection sensor 104 encounters the obstacle, which can reduce the collision damage of the sleeper bolt detection sensor 104. Figure 13 As shown, the detection execution mechanism 1 further comprises an obstacle avoidance mechanism, which further comprises a spring mounting plate 115, a reset spring 116, a rotating pin shaft 117, a plunger 120 and a guide pin shaft 121. The obstacle avoidance mechanism is a mechanism that can swing to pass through the obstacle when the sleeper bolt detection sensor 104 encounters the obstacle, which can reduce the collision damage of the sleeper bolt detection sensor 104. The spring mounting plate 115 is arranged on the lifting frame 103, one end of the reset spring 116 is fixed to the spring mounting plate 115, and the other end is fixed to the guide pin shaft 121. An arc-shaped groove 122 is formed in the lifting frame 103, and the sleeper bolt detection sensor 104 is movably arranged on the lifting frame 103 through the rotating pin shaft 117. The guide pin shaft 121 is rotatably connected with the sleeper bolt detection sensor 104, and the guide pin shaft 121 is located in the arc-shaped groove 122 at the same time. The sleeper bolt detection sensor 104 can rotate around the rotating pin shaft 117, and the guide pin shaft 121 limits the rotation range of the sleeper bolt detection sensor 104. When the sleeper bolt detection sensor 104 collides with the sleeper bolt 8, the sleeper bolt detection sensor 104 can automatically swing to avoid the obstacle, and after the obstacle avoidance action is completed, the reset spring 116 pulls the guide pin shaft 121 to automatically reset the sleeper bolt detection sensor 104. The plunger 120 is arranged on the lifting frame 103, and when the track engineering vehicle 100 is running at high speed, the plunger 120 locks the sleeper bolt detection sensor 104 to prevent the sleeper bolt detection sensor 104 from swinging.

[0072] As shown in FIG. 6, the detection execution mechanism 1 further comprises an obstacle avoidance mechanism, which further comprises a spring mounting plate 115, a reset spring 116, a rotating pin shaft 117, a plunger 120 and a guide pin shaft 121. The obstacle avoidance mechanism is a mechanism that can swing to pass through the obstacle when the sleeper bolt detection sensor 104 encounters the obstacle, which can reduce the collision damage of the sleeper bolt detection sensor 104. Figure 14 and FIG. 7, the detection execution mechanism 1 further comprises an obstacle avoidance mechanism, which further comprises a spring mounting plate 115, a reset spring 116, a rotating pin shaft 117, a plunger 120 and a guide pin shaft 121. The obstacle avoidance mechanism is a mechanism that can swing to pass through the obstacle when the sleeper bolt detection sensor 104 encounters the obstacle, which can reduce the collision damage of the sleeper bolt detection sensor 104. Figure 15As shown, the oil tank 2 is further provided with an oil level window 201, a heater 202, a temperature sensor 203, a filling port 204, an oil suction filter 205, a three-way valve 206 and a ball valve 207. The oil level window 201 is arranged on the side of the oil tank 2 for observing the oil level in the oil tank 2. The heater 202 is inserted into the oil tank 2 for heating the oil in the oil tank 2. The temperature sensor 203 is installed on the side of the oil tank 2 for detecting the temperature of the oil in the oil tank 2. The filling port 204 is arranged on the side of the oil tank for filling oil. The oil suction filter 205, the three-way valve 206 and the ball valve 207 are installed on the front of the oil tank 2. When the temperature sensor 203 detects that the oil temperature is lower than the set temperature, the heater 202 heats the oil to the set temperature and then stops heating, increasing the flowability of the oil when the ambient temperature is low. When the ball valve 207 is in the open state, the three-way valve 206 is connected to the oil inlet of the pressurizing device 3 through a pipeline, and the pressurizing device 3 sucks out the oil through the oil suction filter 205 and pressurizes it.

[0075] The oil tank 2, the pressurizing device 3 and the control system 4 of the oiling operation device 10 are installed on the frame 14 of the rail replacement vehicle or in the cab 16. The detection execution mechanism 1 is installed on the bogie 5 of the rail replacement vehicle or the end beam 15 of the satellite car.

[0076] This embodiment integrates the oiling operation device 10 on the rail replacement vehicle, which can realize oiling operation while on-track operation, greatly improving the operation efficiency. At the same time, the oiling operation device 10 has simple structure, small size and light weight, and is applied to oiling operation under continuous driving, with fast operation speed and high efficiency.

[0077] Embodiment 3

[0078] An embodiment of an on-board rail bolt oiling operation method based on the device described in Embodiment 1, the oiling operation device 10 comprising: a detection execution mechanism 1, an oil tank 2, a pressurizing device 3 and a control system 4. The detection execution mechanism 1 further comprises a sleeper bolt detection sensor 104 and a spray gun 105, and is provided with a lifting mechanism and a locking mechanism. The method specifically comprises the following steps:

[0079] When the oiling operation is performed, the locking mechanism is operated and controlled to perform the unlocking action, and after unlocking, the lifting mechanism is operated by the control system 4 to detect the lowering of the detection execution mechanism 1 to the operation position. During the running of the track engineering vehicle 100, the pressurizing device 3 sucks the oil from the oil tank 2 and pressurizes it to the required pressure. When the sleeper bolt detection sensor 104 detects the sleeper bolt 8, a signal is sent to the control system 4, and the control system 4 determines the time delay according to the collected vehicle speed, controls the time point when the electromagnetic valve 11 opens the (automatic) spray gun 105, and outputs a signal to control the spray gun 105 to open after the time delay, and the high-pressure oil is sprayed onto the sleeper bolt 8 through the spray gun 105, and the sleeper bolt 8 is accurately sprayed, and the oil spraying amount is adjusted by controlling the spraying time. As shown in FIG. 9, it shows the moment when the sleeper bolt 8 is detected, as shown in FIG. 10, it shows the moment when the oil spraying operation is performed, as shown in FIG. 11, it shows the moment when the oil spraying operation is completed, and as shown by L in the figure, it shows the running direction of the track engineering vehicle 100. Figure 16 Figure 17 Figure 18

[0080] The detection execution mechanism 1 further comprises: a mounting bracket 101; an upper fixed plate 123 and a lower fixed plate 124 arranged on the mounting bracket 101; a guide rod 107 arranged between the upper fixed plate 123 and the lower fixed plate 124; and a lifting frame 103 movably arranged on the guide rod 107.

[0081] The lifting mechanism further adopts a lifting cylinder 102, one end of which is fixed to the mounting bracket 101, and the other end is fixed to the lifting frame 103. The sleeper bolt detection sensor 104 is arranged at the bottom front end of the lifting frame 103. The spray guns 105 are arranged at the bottom of the lifting frame 103 and are arranged opposite to each other in pairs in the transverse direction, and the spray guns 105 arranged opposite to each other in the longitudinal direction are arranged at a symmetrical angle. When the oiling operation is performed, the same sleeper bolt 8 is sprayed in the front and rear directions by the spray guns 105.

[0082] The guide rod 107 is further provided with a limiting ring 109, which can move up and down along the length direction of the guide rod 107 and is fixed at different height positions on the guide rod 107 to limit the lowering height of the lifting frame 103, so that the sleeper bolt detection sensor 104 and the spray guns 105 are within the set height range. The guide rod 107 is further provided with an adjusting spring 108 above the limiting ring 109.

[0083] ​​​When the oiling operation is performed, the lifting frame 103 is lowered, and the downward pressure provided by the lifting cylinder 102 compresses the adjusting spring 108, and further fine-tunes the height of the lifting frame 103 to meet the requirements of the oiling operation. When the track engineering vehicle 100 performs the oiling operation on the curve section, the control system 4 controls the lifting cylinder 102 to release the downward pressure, and under the action of the adjusting spring 108, the detection execution mechanism 1 rises to a certain height to compensate for the height influence caused by the lateral tilting of the track engineering vehicle 100.

[0084] The detection execution mechanism 1 further comprises a rising-to-position detection sensor 112 and a locking-to-position detection sensor 113, and the locking mechanism further comprises a locking cylinder 106, a retreat-preventing spring 118 and a locking pin 119. The rising-to-position detection sensor 112 and the locking-to-position detection sensor 113 are both arranged on an upper fixed plate 123, the fixed end of the locking cylinder 106 is mounted on the upper fixed plate 123, and the movable end is connected with the locking pin 119 after being sleeved with the retreat-preventing spring 118.

[0085] When the detection execution mechanism 1 is in a non-working state, the detection execution mechanism 1 is lifted to the position of the driving state under the action of the lifting cylinder 102. The locking cylinder 106 drives the locking pin 119 to realize the locking between the locking portion 125 at the upper portion of the lifting frame 103 and the upper fixed plate 123. The retreat-preventing spring 118 can keep the locking pin 119 in the locking state in the locking state and when the locking cylinder 106 is cut off the gas source. The locking cylinder 106 is locked in place when the locking-to-position detection sensor 113 detects the signal of the locking pin 119. When the detection execution mechanism 1 is in a working state, the locking cylinder 106 pushes the locking pin 119 to be unlocked, and the detection execution mechanism 1 is lowered to the working position under the action of the lifting cylinder 102.

[0086] The detection execution mechanism 1 further comprises an obstacle avoidance mechanism, and the obstacle avoidance mechanism further comprises a spring mounting plate 115, a reset spring 116, a rotating pin shaft 117, a plunger 120 and a guide pin shaft 121. The spring mounting plate 115 is arranged on the lifting frame 103, one end of the reset spring 116 is fixed to the spring mounting plate 115, and the other end is fixed to the guide pin shaft 121. An arc-shaped groove 122 is formed in the lifting frame 103, and the sleeper bolt detection sensor 104 is movably arranged on the lifting frame 103 through the rotating pin shaft 117. The guide pin shaft 121 is rotatably connected with the sleeper bolt detection sensor 104, and the guide pin shaft 121 is located in the arc-shaped groove 122 at the same time. The sleeper bolt detection sensor 104 can rotate around the rotating pin shaft 117, and the guide pin shaft 121 limits the rotation range of the sleeper bolt detection sensor 104.

[0087] When the sleeper bolt detection sensor 104 collides with the sleeper bolt 8, the sleeper bolt detection sensor 104 automatically swings to avoid obstacles, and after the obstacle avoidance action is completed, the guiding pin shaft 121 is pulled by the reset spring 116 to automatically reset the sleeper bolt detection sensor 104.

[0088] The plunger 120 is arranged on the lifting frame 103, and when the track engineering vehicle 100 is running at high speed, the plunger 120 is used to lock the sleeper bolt detection sensor 104 to avoid swinging of the sleeper bolt detection sensor 104.

[0089] The grease tank 2 is further provided with an oil level window 201, a heater 202, a temperature sensor 203, a grease filling port 204, an oil suction filter 205, a three-way valve 206 and a ball valve 207. The heater 202 is inserted into the grease tank 2 and is used for heating the grease in the grease tank 2. The oil level window 201 is used for observing the liquid level of the grease in the grease tank 2. When the temperature sensor 203 detects that the temperature of the grease is lower than the set temperature, the heater 202 stops heating after heating the grease to the set temperature, thereby increasing the flowability of the grease in a low ambient temperature. When the ball valve 207 is in an open state, the three-way valve 206 is connected to the oil suction filter 205 and the oil inlet of the pressurizing device 3 in sequence through pipelines. The pressurizing device 3 sucks out the grease through the oil suction filter 205 and pressurizes the grease.

[0090] It should be particularly noted that in the embodiments of the present application, the lifting cylinder 102 and the locking cylinder 106 can also adopt similar driving structure forms such as an oil cylinder, an electric cylinder, a lead screw and a gear rack, all of which are within the scope of protection of the present application. In addition, the pressurizing device 3 in the embodiments can adopt a structure type such as a pneumatic plunger pump, an electric pump and a gear pump. The cylindrical guide rod 107 and the movement mechanism matched with the sliding sleeve can also be replaced by guide rails of other structures.

[0095] The technical solutions of the vehicle-mounted rail bolt oiling operation device and the rail engineering vehicle described in the embodiments of the present application can produce the following technical effects:

[0096] (1) The vehicle-mounted rail bolt oiling operation device and the rail engineering vehicle described in the embodiments of the present application use a pressurizing device to press the rust-proof grease to the required pressure for atomization, and then use a solenoid valve to control the opening and closing of the air source of the automatic spray gun to control the on-off of the rust-proof grease spraying. The high-pressure rust-proof grease is then atomized and sprayed out through the spray gun. This solves the technical problem that the hydraulic solenoid valve cannot control the on-off of the rust-proof grease at high frequency, and can effectively and comprehensively spray the rail bolt with high quality.

[0097] (2) The vehicle-mounted rail bolt oiling operation device and the rail engineering vehicle described in the embodiments of the present application control the on-off of the rust-proof grease at high frequency, so that the rust-proof grease is atomized and sprayed effectively. When the spray gun moves continuously with the vehicle, the sprayed rust-proof grease can effectively cover the surface of the rail bolt in all directions, greatly improving the oiling operation efficiency.

[0098] (3) The vehicle-mounted rail bolt oiling operation device and the rail engineering vehicle described in the embodiments of the present application use two spray guns arranged at a certain angle to simultaneously perform oiling operation on a target sleeper bolt, solving the technical problem that part of the sprayed rust-proof grease is blocked by the upper end surface of the sleeper bolt, resulting in insufficient coverage of the cylindrical surface of the sleeper bolt.

[0099] (4) The vehicle-mounted rail bolt oiling operation device and the rail engineering vehicle described in the embodiments of the present application use a detection execution mechanism installed near the wheel position, which avoids the technical problem that when the oiling operation device is installed in the middle of the vehicle, the curve segment operation cannot rely on the rail, and at the same time greatly simplifies the structure of the oiling operation device.
