[0002] In automobile assembly workshops, rail transport vehicles are usually used to transport vehicle frames, and workers assemble the frames while the transport vehicles are moving. Rail transport vehicles run on tracks for a long time. If there is no lubricating oil for lubrication, the guide rails will wear, the noise will increase during the operation of the rail transport vehicle, the transmission resistance will also increase, and jamming will occur. Therefore, the tracks need to be inspected and lubricated regularly. In the prior art, it is generally necessary to push the rail transport vehicle on the track away first, and then the workers will manually refuel and lubricate the track. This refueling method is complicated to operate and seriously wastes inspection time. In addition, since the rail transport vehicle needs to be pushed during refueling, the workers' work is relatively dangerous and there are safety hazards. Summary of the invention

[0027] The invention provides a rail refueling device.

[0028] like Figures 1 to 4 As shown, in one embodiment of the present invention, a rail transport vehicle 52 is arranged on the rail 200, and the rail transport vehicle 52 travels on the rail 200. The rail refueling device 100 includes a fuel tank 1, a suction and injection cylinder 2, an oil inlet pipe 3, an oil outlet pipe 4 and a driving assembly 5. The bottom of the fuel tank 1 is provided with an oil supply port 11; the suction and injection cylinder 2 includes a piston 22, a piston rod 23 and a sealed cylinder body 21, and the cylinder body 21 is provided with an oil inlet (not shown) and an oil outlet (not shown). The cylinder body 21 includes a cylinder body 211 and a first cylinder head 212 and a second cylinder head 213 respectively arranged at both ends of the cylinder body 211. The piston 22 is arranged at the cylinder body 211. In the cylinder body 21, the first end of the piston rod 23 passes through the first cylinder head 212 and is connected to the piston 22, and an oil suction chamber 24 is formed between the piston 22 and the second cylinder head 213; the oil inlet is connected to the oil supply port 11 through the oil inlet pipe 3, and a first one-way valve 31 is provided on the oil inlet pipe 3; the inlet of the oil outlet pipe 4 is connected to the oil outlet, and the outlet of the oil outlet pipe 4 is set above the track 200, and a second one-way valve 41 is provided on the oil outlet pipe 4; the driving assembly 5 is connected to the second end of the piston rod 23, and drives the piston rod 23 to reciprocate between the first position and the second position in the cylinder body 21, so that the piston 22 moves away from or close to the second cylinder head 213.

[0029] Figure 1The straight arrow in the middle is the flow direction of the lubricating oil. The oil tank 1 carries the lubricating oil. The second cylinder head 213 and the first cylinder head 212 are respectively arranged at the left and right ends of the cylinder body 211, and the piston rod 23 reciprocates along the left and right directions. When the piston rod 23 of this embodiment is in the first position, the piston 22 is away from the second cylinder head 213 and is located at the rightmost end. When the piston rod 23 is in the second position, the piston 22 is close to the second cylinder head 213 and is located at the leftmost end. The first one-way valve 31 controls the lubricating oil to flow only from the oil supply port 11 to the oil inlet, and the second one-way valve 41 controls the lubricating oil to flow only from the oil outlet to the oil outlet pipe 4. In addition, when the rail transport vehicle 52 is moving on the track 200, the oil tank 1, the suction cylinder 2, the oil inlet pipe 3, the oil outlet pipe 4 and the drive assembly 5 of this embodiment can move with the rail transport vehicle 52. The oil inlet pipe 3 and the oil outlet pipe 4 of this embodiment are both metal pipes, preferably iron alloys, which are easy to obtain and easy to manufacture.

[0030] When the rail refueling device 100 of this embodiment is working, the driving component 5 drives the piston rod 23 to move from the second position to the first position to drive the piston 22 away from the second cylinder head 213. At this time, the suction and injection chamber 24 is in a vacuum state. Due to the hydraulic pressure, and the oil supply port 11 of the oil tank 1 is connected with the oil inlet of the suction and injection cylinder 2, the lubricating oil in the oil tank 1 enters the suction and injection chamber 24 from the oil inlet. When the piston 22 reaches the second position, the suction and injection cylinder 2 completes the oil suction process. The driving component 5 drives the piston rod 23 to move to the first position so that the piston 22 is close to the second cylinder head 213. At this time, the piston 22 pushes the lubricating oil in the suction and injection chamber 24 to flow from the oil outlet into the oil outlet pipe 4, and then from the outlet of the oil outlet pipe 4 to the rail 200 below it, so as to refuel the rail 200. This embodiment utilizes the driving assembly 5 to drive the oil suction cylinder 2 to suck oil, and completes automatic refueling of the track 200 during the movement of the track transport vehicle 52, thereby avoiding the situation where workers manually push the track transport vehicle 52 and manually refuel the track 200, reducing inspection hours while reducing safety hazards.

[0031] In one embodiment, the driving assembly 5 includes a roller 51 and a driving member (not shown), and the second end of the piston rod 23 is connected to the outer edge of the roller 51; the driving member drives the roller 51 to rotate. Figures 2 to 4As shown, the left end of the piston rod 23 is connected to the piston 22, and the right end of the piston rod 23 is connected to the outer edge of the roller 51. The driving member of this embodiment drives the roller 51 to rotate counterclockwise, and during the rotation of the roller 51, the piston rod 23 is driven to reciprocate between the first position and the second position to achieve the oil suction and oil discharge of the suction cylinder 2. The piston rod 23 is driven to reciprocate only by the cooperation of the roller 51 and the driving member, and the structure is simple and ingenious. For the convenience of manufacturing, in this embodiment, the oil inlet and the oil outlet are both opened in the second cylinder head 213, and the oil inlet and the oil outlet are both opened in the second cylinder head 213, so that the lubricating oil in the suction and injection chamber 24 can flow out from the oil outlet as much as possible. In other embodiments, the oil outlet and the oil inlet are opened in the cylinder body 211.

[0032] like Figures 1 to 4 As shown, the oil inlet and the oil outlet of this embodiment are shared, that is, the oil inlet and the oil outlet are the same opening opened in the second cylinder head 213, and the opening can be used as both the oil inlet and the oil outlet. The rail refueling device 100 includes a connecting pipe 6, one end of which is connected to the oil inlet, and the other end of which is connected to the outlet of the oil inlet pipe 3 and the inlet of the oil outlet pipe 4. The suction and injection cylinder 2 only has one through hole to complete the process of suction and injection, which has a simple structure and strengthens the airtightness of the cylinder body 21 to avoid oil leakage. Figures 2 to 4 As shown, there are two tracks 200 in this embodiment, and the outlet of the oil outlet pipe 4 is connected to two sub-oil outlet pipes 42 through a three-way valve. The outlets of the two sub-oil outlet pipes 42 are respectively arranged above the two tracks 200, and the outlets of the two sub-oil outlet pipes 42 are both provided with oil spray nozzles 421. The two sub-oil outlet pipes 42 are connected through the outlet of the oil outlet pipe 4. When the driving member drives the suction cylinder 2, the two tracks 200 can be refueled at the same time, which saves the refueling time, and the structure is simple and easy to manufacture. The outlets of the oil outlet pipes 4 are all provided with oil spray nozzles 421, which can spray the lubricating oil on the track 200 as evenly as possible.

[0033] Specifically, the rail refueling device 100 further includes a switch (not shown), which is connected to the driving member and controls the start and stop of the driving member. The electrical connection relationship between the driving member and the switch is a mature prior art, and the switch controls the start and stop of the driving member by controlling the on and off between the driving member and the external power supply. The worker only needs to control the start and stop of the driving member by operating the switch, thereby controlling whether the rail refueling device 100 is refueled. The structure is simple and easy to operate, avoiding the worker from manually refueling the rail 200.

[0034] In another embodiment, the driving member is a rail transport vehicle 52, and the rail transport vehicle 52 drives the roller 51 to roll and contact with the rail 200. While the rail transport vehicle 52 is walking on the rail 200, it drives the roller 51 to rotate along the rail 200 to drive the oil suction and oil discharge of the suction and injection cylinder 2, avoiding the manual pushing of the rail transport vehicle 52 by the worker, reducing the setting of the power source, and the structure is ingenious and energy-saving. The rail refueling device 100 also includes a lifting component 7 connected to the roller 51, and the lifting component 7 drives the roller 51 to approach or move away from the rail 200. When the lifting component 7 controls the roller 51 to approach the rail 200, the rail transport vehicle 52 drives the roller 51 to roll and contact with the rail 200, which can drive the oil suction and oil discharge of the suction and injection cylinder 2. When the lifting component 7 controls the roller 51 to move away from the rail 200, the rail transport vehicle 52 cannot drive the roller 51 to roll and contact with the rail 200, thereby realizing the shutdown of the rail refueling device 100. The start and stop of the rail refueling device 100 can be controlled only by controlling the lifting component 7, and the structure is ingenious.

[0035] Specifically, the lifting assembly 7 includes a mounting block 71 and a screw 72. The mounting block 71 is mounted on the rail transport vehicle 52. The mounting block 71 is provided with a through hole. The upper end of the screw 72 passes through the through hole and is mounted on the mounting block 71 through a nut 73. The lower end of the screw 72 is connected to the roller 51. When the track 200 needs to be refueled, the worker manually loosens the nut 73, drives the roller 51 down with the screw 72, and the roller 51 contacts the track 200. The rail transport vehicle 52 drives the roller 51 to roll and contact with the track 200. When the refueling of the track 200 is completed, the worker manually tightens the nut 73, and the screw 72 drives the roller 51 to rise. This embodiment controls the start and stop of the track refueling device 100 only by the tightness of the nut 73, and has a simple structure and is easy to install and operate.

[0036] like Figures 2 to 4 As shown, the rail transport vehicle 52 of this embodiment is provided with a cantilever 521, and the oil tank 1, the oil suction cylinder 2, the oil outlet pipe 4 and the oil inlet pipe 3 are all installed on the cantilever 521. The oil tank 1, the oil suction cylinder 2, the oil outlet pipe 4 and the oil inlet pipe 3 are integrated into the rail transport vehicle 52 through the cantilever 521, so that when the rail refueling device 100 refuels, the rail 200 is refueled at the same time as the rail transport vehicle 52 moves, and the structure is simple and easy to assemble.

[0037] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
