Description

Technical Field

[0001] The present application relates to the technical field of railway engineering machinery, and in particular to a device for oiling vehicle-mounted rail bolts and a rail engineering vehicle. Background Art

[0002] With the development of rail transit construction, railway speed increase and heavy load, the workload of track maintenance is increasing, and the requirements for maintenance quality are also increasing. Among them, as an important part of railway maintenance, rail line sleeper bolts need to be regularly oiled for rust prevention. At present, the oiling of railway fasteners is usually done manually or semi-manually using some small hand-push bolt oiling equipment, which has low efficiency and the quality of oiling cannot be kept stable.

[0003] The existing technology usually uses a hydraulic solenoid valve to directly control the start and stop of the spraying medium. Due to the performance limitations of the hydraulic solenoid valve, it is usually not suitable for spraying high-viscosity anti-rust grease, and can only use anti-rust oil with low viscosity and low fluidity for automatic oiling operations. Therefore, most of the existing automatic oiling equipment can only be used for spraying anti-rust oil, while the use of anti-rust grease for spraying anti-rust in actual oiling operations has a better anti-rust effect. In addition, the existing spraying method cannot perform high-frequency on-off control of atomized spraying of anti-rust grease, and most of the existing spraying methods use a nozzle to spray the sleeper bolts (or fasteners) vertically downward, and cannot effectively spray the cylindrical surface of the bolt in all directions.

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

[0005] Prior art 1 is a Chinese invention application filed by Huainan Mining (Group) Co., Ltd. on September 24, 2021 and published on December 10, 2021, with publication number CN113769920A. The application discloses an automatic oil spraying device and an oil spraying method for sleeper bolts. The automatic oil spraying device is installed on a track-lifting device of a tamping vehicle, and includes a mounting bracket, a screw, a motor, a limit block, a bolt detection sensor, an oil circuit and an air circuit, etc. The mounting bracket is installed on the track-lifting device of the tamping vehicle. The mounting base plate is fixedly mounted on the mounting bracket, the mounting bracket is provided with a cavity, the screw is rotatably mounted in the cavity, the motor is mounted at one end of the mounting bracket, and the motor is connected to the screw. The slider is arranged in the cavity and is threadedly connected to the screw, the limiter is fitted on one side of the mounting base plate, and the limiter is connected to the slider. The limiter has a downward mounting column, and the third proximity switch and the oil nozzle are mounted on the mounting column. The oil circuit and air circuit system are connected to the oil nozzle. The control system is connected to the first proximity switch, the second proximity switch, the third proximity switch and the oil and air circuit system. The device is used for step-by-step operation. During operation, the vehicle must be in a stopped state. The motor drives the lead screw to drive the bolt detection sensor and the nozzle positioning bolt, and then the grease is sprayed through the oil circuit and the air circuit. The oil circuit of the automatic oil spraying device in the application has no booster device, and compressed gas is used to atomize and spray the grease. The spraying effect is not good and the operation quality is not high.

[0006] Prior art 2 is a Chinese invention application filed by Zhuzhou Times Electronic Technology Co., Ltd. on July 11, 2022 and published on October 18, 2022, with publication number CN115198582A. The application discloses a sleeper bolt oiling device and a railway engineering operation vehicle including the device. The sleeper bolt oiling device is installed in the middle of the engineering operation away from the wheel position, and mainly includes a lifting drive mechanism, a main frame, a rail oiling mechanism and a locking mechanism. The main frame includes a first fixed frame and a crossbeam, and the first fixed frame is installed at the bottom of the frame. The upper part of the lifting drive mechanism is connected to the frame, and the lower part is connected to the crossbeam. The crossbeam can be lifted and lowered relative to the first fixed frame under the drive of the lifting drive mechanism. The rail oiling mechanism is installed on the left and right sides of the crossbeam to realize rail running and bolt oiling operations. When the sleeper bolt signal is detected, the rail oiling mechanism oils the sleeper bolts. This application mainly solves the technical problem of the oiling device leaning against the track during curved section operation when the oiling device is in the middle of the vehicle, but the structure of this oiling device is relatively complex.

[0007] Prior art 3 is a Chinese utility model patent applied for by Xi'an Yishengda Technology Co., Ltd. on January 28, 2021, and announced on October 22, 2021, with the announcement number CN214467762U. The patent discloses an integrated device for automatic tightening and oiling of railway sleeper bolt fasteners, including a shield, an air pump, an oil tank, a pressure regulating valve, a positioning seat, an optical axis, a cylinder, a walking motor, a linear bearing and a positioning seat arranged in sequence on the upper part of the bottom frame along one direction. It also includes casters, a driving wheel, an air tank and a driven wheel arranged at the lower part of the bottom frame. The device pressurizes the grease by directly injecting compressed air into the oil tank, and the spraying adopts air-assisted spraying. However, this spraying device is only suitable for anti-rust oil spraying for the oiling operation of the sleeper bolts, and the high-frequency on-off control of the atomization spraying of the anti-rust grease cannot be performed. Summary of the invention

[0008] In view of this, the purpose of the present application is to provide a vehicle-mounted rail bolt oiling operation device and a rail engineering vehicle to solve the technical problems that the existing oiling operation device cannot effectively spray the rail bolts in all directions and the oiling operation quality is not high.

[0009] In order to achieve the above-mentioned invention purpose, the present application specifically provides a technical implementation scheme of a vehicle-mounted rail bolt oiling operation device. The operation device runs on the track with the rail engineering vehicle, and includes: a detection actuator, a grease tank, a pressurizing device and a control system. The detection actuator includes a sleeper bolt detection sensor and a spray gun. When the oiling operation is performed, the pressurizing device sucks grease from the grease tank and pressurizes it to the required pressure. When the sleeper bolt detection sensor detects the sleeper bolt, it sends a signal to the control system. The control system determines the delay time according to the collected vehicle speed. After the delay, the output signal controls the air circuit to open through the solenoid valve, and the high-pressure grease is sprayed onto the sleeper bolt through the spray gun.

[0010] Furthermore, the detection execution mechanism includes:

[0011] Mounting bracket;

[0012] An upper fixing plate and a lower fixing plate disposed on the mounting bracket;

[0013] A guide rod disposed between the upper fixing plate and the lower fixing plate;

[0014] A lifting frame movably arranged on the guide rod;

[0015] One end is fixed to the mounting bracket, and the other end is fixed to the lifting cylinder of the lifting frame;

[0016] A sleeper bolt detection sensor disposed at the front end of the bottom of the lifting frame;

[0017] The spray guns disposed at the bottom of the lifting frame and arranged opposite to each other in pairs in the transverse direction and opposite to each other in the longitudinal direction are arranged at symmetrical angles to perform spraying operations on the same sleeper bolt.

[0018] Furthermore, a limit ring is provided on the guide rod, and the limit ring can move up and down along the length direction of the guide rod and be fixed at different height positions on the guide rod to limit the descending height of the lifting frame so that the sleeper bolt detection sensor and the spray gun are within the set height range.

[0019] Furthermore, the guide rod is provided with an adjustment spring, which is located above the limit ring. When the oiling operation is performed, the lifting frame descends, and the downward force provided by the lifting cylinder compresses the adjustment spring, thereby fine-tuning the height of the lifting frame to meet the requirements of the oiling operation.

[0020] Furthermore, the detection actuator also includes a locking mechanism, a rising in place detection sensor and a locking in place detection sensor, and the locking mechanism includes a locking cylinder, a backstop spring and a locking pin. The rising in place detection sensor and the locking in place detection sensor are both arranged on the upper fixed plate, the fixed end of the locking cylinder is installed on the upper fixed plate, and the outer side of the movable end is sleeved with a backstop spring and connected to the locking pin. When the detection actuator is in a non-working state, under the action of the lifting cylinder, the detection actuator is lifted to the position of the driving state. The locking pin is driven by the locking cylinder to achieve the locking between the locking part of the upper part of the lifting frame and the upper fixed plate. The backstop spring can keep the locking pin in the locked state when the locking cylinder cuts off the air source in the locked state. When the locking in place detection sensor detects the signal of the locking pin, the locking cylinder is locked in place. When the detection actuator is in a working state, the locking cylinder pushes the locking pin to unlock, and under the action of the lifting cylinder, the detection actuator descends to the working position.

[0021] Furthermore, the lifting frame is provided with an air distribution block for distributing the air source to different spray guns, thereby providing a power source for opening and closing the spray guns.

[0022] Furthermore, the detection actuator also includes an obstacle avoidance mechanism, which includes a spring mounting plate, a reset spring, a rotating pin and a guide pin. The spring mounting plate is arranged on the lifting frame, one end of the reset spring is fixed to the spring mounting plate, and the other end is fixed to the guide pin. The lifting frame is provided with an arc groove, and the sleeper bolt detection sensor is movably arranged on the lifting frame through a rotating pin. The guide pin is rotatably connected to the sleeper bolt detection sensor, and the guide pin is simultaneously located in the arc groove. The sleeper bolt detection sensor can rotate around the rotating pin, and the guide pin limits the rotation range of the sleeper bolt detection sensor. When the sleeper bolt detection sensor collides with the sleeper bolt, the sleeper bolt detection sensor can automatically swing to avoid obstacles, and when the obstacle avoidance action is completed, the reset spring pulls the guide pin to automatically reset the sleeper bolt detection sensor. When the rail engineering vehicle is running at high speed, the sleeper bolt detection sensor is locked by a plunger to prevent the sleeper bolt detection sensor from swinging.

[0023] Furthermore, the obstacle avoidance mechanism further comprises a plunger, and the plunger is arranged on the lifting frame. When the rail engineering vehicle is running at high speed, the plunger is used to lock the sleeper bolt detection sensor to prevent the sleeper bolt detection sensor from swinging.

[0024] Furthermore, the grease box is provided with an oil level window, a heater, a temperature sensor, a refueling port, an oil suction filter, a three-way valve and a ball valve. The heater is inserted into the grease box to heat the grease in the grease box, and the oil level window is used to observe the liquid level of the grease in the grease box. When the temperature sensor detects that the grease temperature is lower than the set temperature, the heater heats the grease to the set temperature and then stops heating, thereby increasing the fluidity of the grease when the ambient temperature is low. When the ball valve is in an open state, the three-way valve is connected to the oil inlet of the pressurizing device through a pipeline, and the pressurizing device sucks out the grease through the oil suction filter and pressurizes it.

[0025] The present application further specifically provides a technical implementation solution for a rail engineering vehicle, including: the vehicle-mounted rail bolt oiling operation device as described above, wherein the detection actuator of the oiling operation device is installed close to the wheel of the rail engineering vehicle.

[0026] Furthermore, the rail engineering vehicle is a track-changing vehicle.

[0027] Furthermore, the grease tank, pressurizing device and control system of the oiling operation device are installed on the frame of the rail-changing vehicle or in the driver's cab.

[0028] Furthermore, the detection actuator is installed on the bogie of the track-changing vehicle or the end beam of the satellite vehicle.

[0029] By implementing the above-mentioned technical solution of the vehicle-mounted rail bolt oiling operation device and rail engineering vehicle provided by the present application, the following beneficial effects are achieved:

[0030] (1) The vehicle-mounted rail bolt oiling operation device and rail engineering vehicle of the present application use a pressurizing device to pressurize the anti-rust grease to the pressure required for atomization, and then control the on-off of the anti-rust grease spraying by controlling the switch air source of the automatic spray gun. The high-pressure anti-rust grease is then atomized and sprayed out through the spray gun, which can perform all-round, effective and high-quality spraying on the rail bolts;

[0031] (2) The vehicle-mounted rail bolt oiling operation device and rail engineering vehicle of the present application have a good atomization spraying effect of the anti-rust grease by performing high-frequency on-off control of the anti-rust grease. When the spray gun moves with the vehicle to perform continuous spraying operations, the sprayed anti-rust grease can effectively cover the surface of the rail bolts in all directions, greatly improving the efficiency of the oiling operation;

[0032] (3) The vehicle-mounted rail bolt oiling operation device and rail engineering vehicle of the present application use two spray guns arranged at a certain angle to simultaneously oil a target rail sleeper bolt, thereby solving the technical problem that part of the sprayed anti-rust grease is blocked by the upper end surface of the rail sleeper bolt, resulting in insufficient coverage of the cylindrical surface of the rail sleeper bolt;

[0033] (4) In the vehicle-mounted rail bolt oiling operation device and rail engineering vehicle of the present application, the detection actuator is installed close to the wheel position, which avoids the technical problem that the oiling operation device cannot be close to the track during curved section operation when it is installed in the middle of the vehicle, and at the same time greatly simplifies the structure of the oiling operation device.

DETAILED DESCRIPTION

[0054] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] As attached Figure 1 To Attachment Fig.18 As shown, a specific embodiment of the vehicle-mounted rail bolt oiling operation device and the rail engineering vehicle of the present application is given, and the present application is further explained below in conjunction with the drawings and specific embodiments.

[0056] The following specific embodiments take the rail-changing vehicle as an example to explain the technical solution of the present application in detail. The vehicle-mounted 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 the oiling operation of small rail trolleys.

[0057] Example 1

[0058] As attached Figure 1 To Attachment Figure 7 As shown, an embodiment of the vehicle-mounted rail bolt oiling operation device of the present application, the oiling operation device 10 runs on the track 6 with the rail engineering vehicle 100, and specifically includes: a detection actuator 1, a grease box 2, a pressurizing device 3 and a control system 4. The installation positions of each component are shown in the attached figure. Figure 1 As shown. The detection actuator 1 further includes a sleeper bolt detection sensor 104 and a spray gun 105. The detection actuator 1 is installed on the bogie 5 near the wheel 9. In this embodiment, it is installed on the end beam 15 of the bogie 5. The sleeper bolt detection sensor 104 is installed at the lowest part of the detection actuator 1. Its main function is to detect the position of the railway track spike (i.e., the sleeper bolt 8) and transmit the detection signal to the control system 4. The grease in the grease tank 2 is connected to the oil circuit 13 of the spray gun 105 through the pressurizing device 3. When the oiling operation is performed, the pressurizing device 3 uses the compressed air of the vehicle as the power to suck out the grease from the grease tank 2 and pressurize it to the required pressure. When the sleeper bolt detection sensor 104 (passing above the sleeper bolt 8) detects the sleeper bolt 8, it sends a signal to the control system 4. The control system 4 determines the delay time according to the collected vehicle speed. After the delay, the output signal controls the air circuit 12 to open through the solenoid valve 11, and the high-pressure grease is sprayed on the target sleeper bolt 8 of the sleeper 7 through the spray gun 105.

[0059] This embodiment adopts a pneumatic automatic spray gun control mode, and controls the switch of the spray gun 105 through the solenoid valve 11 of the air circuit 12, which can be applicable to the atomization oiling operation of the special anti-rust and anti-corrosion grease for railway sleeper bolts, and can also realize a higher frequency of on-off control, so that the oiling operation efficiency of the oiling operation device 10 is greatly improved. The oiling operation device 10 described in Example 1 has a simple structure, can be applicable to the automatic oiling operation of high-viscosity anti-rust grease, and has the advantages of fast operation speed and good oiling effect.

[0060] As attached Figure 8 To Attachment Fig.10 As shown, the detection actuator 1 has the functions of lifting, locking, road spike detection, spraying and sensor obstacle avoidance, and further includes:

[0061] Mounting bracket 101; the mounting bracket 101 is the mounting body of the detection actuator 1, and the remaining components of the detection actuator 1 are connected to the vehicle body through the mounting bracket 101; the mounting bracket 101 is mounted on the mounting plate 110 of the end beam 15 by bolts, and the bolts between the mounting bracket 101 and the mounting plate 110 are also provided with shock-absorbing pads 111;

[0062] An upper fixing plate 123 and a lower fixing plate 124 disposed on the mounting bracket 101;

[0063] A guide rod 107 is disposed between the upper fixing plate 123 and the lower fixing plate 124; the guide rod 107 is fixed to the mounting bracket 101, and the two guide rods 107 are arranged in parallel, and the guide rod 107 provides a guide for the lifting and lowering movement of the remaining parts of the actuator;

[0064] A lifting frame 103 movably disposed on the guide rod 107; a sliding sleeve may also be disposed on the lifting frame 103, and the sliding sleeve forms a motion matching relationship with the guide rod 107 to realize the lifting action;

[0065] One end is fixed to the mounting bracket 101, and the other end is fixed to the lifting cylinder 102 of the lifting frame 103, which provides power for the lifting movement of the detection actuator 1;

[0066] A sleeper bolt detection sensor 104 disposed at the front end of the bottom of the lifting frame 103;

[0067] It is arranged at the bottom of the lifting frame 103 and extends in the horizontal direction (such as the attached Fig. 9 The spray guns 105 are arranged opposite to each other in pairs (in the direction shown in FIG. Fig.10 The spray guns 105 arranged relative to each other (in the direction shown in B) are arranged at symmetrical angles at the same time to spray the same sleeper bolt 8. In order to achieve a good spraying effect on the surface of the sleeper bolt 8, two spray guns 105 are arranged at symmetrical angles along the working direction to cross-spray the same sleeper bolt 8. As a typical specific embodiment of the present invention, a detection actuator 1 is equipped with four spray guns 105, and the detection actuators 1 corresponding to the rails 6 on both sides are equipped with a total of eight spray guns 105. Among them, 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, the oil supply of the four spray guns 105 can also be achieved by changing the pipeline installation and adopting a parallel mode. However, compared with the parallel oil supply, the series oil supply method greatly reduces the use of oil pipes. The method of using two spray guns 105 arranged at symmetrical angles to spray the same sleeper bolt in this embodiment has a better coating effect than the prior art that uses one nozzle to vertically spray the sleeper bolt 8.

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

[0069] An adjustment spring 108 is also provided on the guide rod 107, and the adjustment spring 108 is located on the limit ring 109. When the oiling operation is performed, the lifting frame 103 descends, and the downward pressure provided by the lifting cylinder 102 compresses the adjustment spring 108. The expansion and contraction of the adjustment spring 108 is achieved by controlling the downward pressure of the lifting cylinder 102, and then the height of the lifting frame 103 is finely adjusted to meet the requirements of the oiling operation.

[0070] As attached Fig.11 As shown, the detection actuator 1 also includes a locking mechanism, a rising position detection sensor 112 and a locking position detection sensor 113. The locking mechanism further includes a locking cylinder 106, a backstop spring 118 and a locking pin 119. The rising position detection sensor 112 and the locking position detection sensor 113 are both arranged on the upper fixed plate 123. The fixed end of the locking cylinder 106 is mounted on the upper fixed plate 123, and the outer side of the movable end is sleeved with a backstop spring 118 and connected to the locking pin 119. The rising position detection sensor 112 is used to detect whether the lifting frame 103 has risen to the position. Only when the rising position detection sensor 112 detects that it has risen to the position, the locking action will be executed. 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, pushing the locking pin 119 to move, and realizing the locking and unlocking functions. When the detection actuator 1 is in a non-working state, the detection actuator 1 is lifted to the driving state position under the action of the lifting cylinder 102, and the locking mechanism can lock the moving parts to ensure that they remain in the driving state position to ensure driving safety. The locking cylinder 106 drives the locking pin 119 to achieve the locking between the locking part 125 on the upper part of the lifting frame 103 and the upper fixing plate 123. Fig.12As shown, an air path distribution block 114 is provided on the lifting frame 103, which is used to distribute the air source controlled by the solenoid valve group to different spray guns 105, and provide a power source for the opening and closing of the spray gun 105. The stop spring 118 can keep the locking pin 119 in the locked state when the locking cylinder 106 cuts off the air source in the locked state, thereby ensuring reliable locking. When the locking-in-place detection sensor 113 detects the signal of the locking pin 119, the control system 4 considers that the locking cylinder 106 is locked in place, otherwise a fault alarm will be issued. When the detection actuator 1 is in working state, the locking cylinder 106 pushes the locking pin 119 to unlock, and under the action of the lifting cylinder 102, the detection actuator 1 descends to the working position.

[0071] When the rail 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 are foreign objects on the track, the sleeper bolt detection sensor 104 will collide with the obstacle and cause sensor damage. Fig.13 As shown, the detection actuator 1 also includes an obstacle avoidance mechanism, which further includes a spring mounting plate 115, a reset spring 116, a rotating pin 117, a plunger 120 and a guide pin 121. The obstacle avoidance mechanism is a mechanism that allows the sleeper bolt detection sensor 104 to swing when encountering an obstacle to pass through the obstacle, thereby reducing the collision damage suffered by 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 121. An arc groove 122 is provided on the lifting frame 103, and the sleeper bolt detection sensor 104 is movably arranged on the lifting frame 103 through the rotating pin 117. The guide pin 121 is rotatably connected to the sleeper bolt detection sensor 104, and the guide pin 121 is also located in the arc groove 122. The sleeper bolt detection sensor 104 can rotate around the rotating pin 117, and the guide pin 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 obstacles. After the obstacle avoidance action is completed, the reset spring 116 pulls the guide pin 121 to automatically reset the sleeper bolt detection sensor 104. The plunger 120 is set on the lifting frame 103. When the rail 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 attached Fig.14 and attached Fig.15As shown, the grease tank 2 is further provided with an oil level window 201, a heater 202, a temperature sensor 203, a refueling port 204, an oil suction filter 205, a three-way valve 206 and a ball valve 207. The oil level window 201 is provided on the side of the grease tank 2 for observing the liquid level of the grease in the grease tank 2. The heater 202 is inserted into the grease tank 2 for heating the grease in the grease tank 2. The temperature sensor 203 is installed on the side of the grease tank 2 for detecting the temperature of the grease in the grease tank 2. The refueling port 204 is provided on the side of the grease tank for filling the grease. The oil suction filter 205, the three-way valve 206 and the ball valve 207 are installed on the front of the grease tank 2. When the temperature sensor 203 detects that the grease temperature is lower than the set temperature, the heater 202 heats the grease to the set temperature and then stops heating, thereby increasing the fluidity of the grease when the ambient temperature is low. When the ball valve 207 is in an 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 grease through the oil suction filter 205 and pressurizes it.

[0073] Example 2

[0074] As attached Figure 1 As shown, an embodiment of a rail engineering vehicle 100 based on the device described in Example 1 specifically includes: the vehicle-mounted rail bolt oiling operation device as described in Example 1, and the detection actuator 1 of the oiling operation device 10 is installed close to the wheel 9 of the rail engineering vehicle 100. As a typical specific embodiment of the present invention, the rail engineering vehicle 100 is further a rail-changing vehicle.

[0075] The grease 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-changing vehicle or in the driver's cab 16. The detection actuator 1 is installed on the bogie 5 of the rail-changing vehicle or the end beam 15 of the satellite vehicle.

[0076] In this embodiment, the oiling operation device 10 is integrated and installed on the rail-changing vehicle, so that the oiling operation can be performed while the rails are being operated, which greatly improves the operation efficiency. At the same time, the oiling operation device 10 has a simple structure, a small size, and a light weight, and is applied to the oiling operation under continuous driving, with a fast operation speed and high efficiency.

[0077] Example 3

[0078] An embodiment of a vehicle-mounted rail bolt oiling operation method based on the device described in Example 1, the oiling operation device 10 includes: a detection actuator 1, a grease box 2, a pressurizing device 3 and a control system 4. The detection actuator 1 further includes a sleeper bolt detection sensor 104 and a spray gun 105, and the detection actuator 1 is provided with a lifting mechanism and a locking mechanism. The method specifically includes the following steps:

[0079] When the oiling operation is performed, the locking mechanism is operated and controlled to perform the unlocking action. After unlocking, the lifting mechanism is operated through the control system 4 to detect that the actuator 1 has descended to the operating position. During the movement of the rail engineering vehicle 100, the pressurizing device 3 sucks grease from the grease tank 2 and pressurizes it to the required pressure. When the sleeper bolt detection sensor 104 detects the sleeper bolt 8, it sends a signal to the control system 4. The control system 4 determines the delay time according to the collected vehicle speed, controls the solenoid valve 11 to open (automatically) the time point of the spray gun 105, and controls the spray gun 105 to open after the output signal delay. The high-pressure grease is sprayed onto the sleeper bolt 8 through the spray gun 105, and the sleeper bolt 8 is accurately sprayed. The grease spraying amount is adjusted by controlling the spraying time. As shown in the attached figure Fig.16 The figure shows the moment when the sleeper bolt 8 is detected. Fig.17 The following table shows the time of grease spraying operation. Fig.18 The time when the grease spraying operation is finished is shown, and L in the attached figure indicates the traveling direction of the rail engineering vehicle 100.

[0080] The detection actuator 1 further includes: a mounting bracket 101 ; an upper fixing plate 123 and a lower fixing plate 124 disposed on the mounting bracket 101 ; a guide rod 107 disposed between the upper fixing plate 123 and the lower fixing plate 124 ; and a lifting frame 103 movably disposed 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 two in the horizontal direction. 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 spray gun 105 is used to spray the same sleeper bolt 8 in the front and rear directions.

[0082] A limit ring 109 is further provided on the guide rod 107. The limit ring 109 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 sleeper bolt detection sensor 104 and the spray gun 105 are within a set height range. An adjustment spring 108 is further provided on the guide rod 107, and the adjustment spring 108 is located on the limit ring 109.

[0083] When the oiling operation is performed, the lifting frame 103 descends, and the downward pressure provided by the lifting cylinder 102 compresses the adjustment spring 108, thereby fine-tuning the height of the lifting frame 103 to meet the requirements of the oiling operation. When the rail engineering vehicle 100 is oiling in a curved section, the lifting cylinder 102 is controlled by the control system 4 to release the downward pressure, and under the action of the adjustment spring 108, the detection actuator 1 rises to a certain height to compensate for the height effect caused by the roll of the rail engineering vehicle 100.

[0084] The detection actuator 1 also includes a rising in place detection sensor 112 and a locking in place detection sensor 113, and the locking mechanism further includes a locking cylinder 106, a backstop spring 118 and a locking pin 119. The rising in place detection sensor 112 and the locking in place detection sensor 113 are both arranged on the upper fixed plate 123, the fixed end of the locking cylinder 106 is mounted on the upper fixed plate 123, and the outer side of the movable end is sleeved with a backstop spring 118 and connected to the locking pin 119.

[0085] When the detection actuator 1 is in a non-working state, the detection actuator 1 is lifted to the driving state position under the action of the lifting cylinder 102. The locking cylinder 106 drives the locking pin 119 to realize the locking between the locking part 125 on the upper part of the lifting frame 103 and the upper fixed plate 123. The stop spring 118 can keep the locking pin 119 in the locked state when the locking cylinder 106 cuts off the air supply in the locked state. When the locking in place detection sensor 113 detects the signal of the locking pin 119, the locking cylinder 106 is locked in place. When the detection actuator 1 is in a working state, the locking cylinder 106 pushes the locking pin 119 to unlock, and under the action of the lifting cylinder 102, the detection actuator 1 descends to the working position.

[0086] The detection actuator 1 also includes an obstacle avoidance mechanism, which further includes a spring mounting plate 115, a reset spring 116, a rotating pin 117, a plunger 120 and a guide pin 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 121. An arc groove 122 is provided on the lifting frame 103, and the sleeper bolt detection sensor 104 is movably arranged on the lifting frame 103 through the rotating pin 117. The guide pin 121 is rotatably connected to the sleeper bolt detection sensor 104, and the guide pin 121 is simultaneously located in the arc groove 122. The sleeper bolt detection sensor 104 can rotate around the rotating pin 117, and the guide pin 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 the obstacle. 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.

[0088] The plunger 120 is disposed on the lifting frame 103 . When the rail engineering vehicle 100 is traveling at a high speed, the plunger 120 is used to lock the sleeper bolt detection sensor 104 to prevent the sleeper bolt detection sensor 104 from swinging.

[0089] The grease tank 2 is further provided with an oil level window 201, a heater 202, a temperature sensor 203, a refueling 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 to heat the grease in the grease tank 2, and the oil level window 201 is used to observe the liquid level of the grease in the grease tank 2. When the temperature sensor 203 detects that the grease temperature is lower than the set temperature, the heater 202 heats the grease to the set temperature and then stops heating to increase the fluidity of the grease when the ambient temperature is low. 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 a pipeline, and the pressurizing device 3 sucks out the grease through the oil suction filter 205 and pressurizes it.

[0090] It should be noted that in the embodiment of the present application, the lifting cylinder 102 and the locking cylinder 106 can also adopt similar drive structures such as oil cylinders, electric cylinders, lead screws, gear racks, etc., all of which are within the scope of protection requested by the present application. In addition, the pressurizing device 3 in the present embodiment can adopt structural types such as pneumatic plunger pumps, electric pumps, gear pumps, etc., and the motion mechanism in which the cylindrical guide rod 107 cooperates with the sliding sleeve can also be replaced by guide rails of other structures.

[0096] (1) The on-board rail bolt oiling operation device and rail engineering vehicle described in the specific embodiments of the present application use a pressurizing device to pressurize the anti-rust grease to the pressure required for atomization, and then control the on-off control of the anti-rust grease spraying by controlling the switch air source of the automatic spray gun through the solenoid valve.

[0098] (3) The vehicle-mounted rail bolt oiling operation device and rail engineering vehicle described in the specific embodiments of the present application use two spray guns arranged at a certain angle to simultaneously oil a target sleeper bolt, thereby solving the technical problem that part of the sprayed anti-rust 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) In the vehicle-mounted rail bolt oiling operation device and rail engineering vehicle described in the specific embodiments of the present application, the detection actuator is installed close to the wheel position, which avoids the technical problem that the oiling operation device cannot be close to the track during curved section operation when it is installed in the middle of the vehicle, and at the same time greatly simplifies the structure of the oiling operation device.
