Referring to fig. 1, the present embodiment provides a refueling mechanism 10, which can be applied to a gas station or a tank truck, and is used for filling oil into other vehicles or engineering machinery, so as to effectively improve the oil filling efficiency and shorten the oil filling time. This refueling mechanism 10 includes arm 100 and refuel executor 200, refuel executor 200 includes mounting bracket 210, lift assembly 220 and oil pipe 230, and arm 100 is connected with mounting bracket 210, and lift assembly 220 locates on mounting bracket 210, and lift assembly 220 is connected with oil pipe 230 for drive oil pipe 230 removes, so that oil pipe 230 is to oiling in stretching into the state to the oil tank 30 bottom in oil pipe 230. The lifting assembly 220 can extend the oil pipe 230 into the bottom of the oil tank 30, and in the oil filling process, the oil outlet 330 of the oil pipe 230 is quickly submerged by oil liquid, so that the oil filling speed can be quickly increased, the oil filling time is shortened, and the oil filling efficiency is improved.
It is understood that according to the electrostatic safety regulations (GB13348-2009) for liquid petroleum products, for oil with a conductivity below 50pS/m, the initial flow rate should not be greater than 1m/s before the injection port is submerged, and when the injection port is submerged for 200mm, the flow rate can be gradually increased, but the maximum flow rate should not be greater than 7 m/s. In this embodiment, since the oil pipe 230 extends into the bottom of the oil tank 30 for filling, the oil filling port 231 of the oil pipe 230 is rapidly immersed by the oil, and when the oil filling port 231 is immersed by 200mm, the oil filling rate can be greatly increased, and the oil filling rate can be increased to 7m/s at most. Optionally, the highest oiling efficiency can reach 1900L/min, quick and safe oiling can be realized for engineering machinery, agricultural machinery or ship machinery and the like, the method can also be applied to the field of other vehicles, and the oiling operation efficiency can be greatly improved.

The driving member 221 may be, but not limited to, a motor 2211, and the motor 2211 is directly or indirectly connected to the first transmission shaft 223, for example, the driving member 221 includes a motor 2211 and a speed reducer 2213, the motor 2211 is connected to the speed reducer 2213, and the speed reducer 2213 is connected to the first transmission shaft 223 to rotate the first transmission shaft 223. The driving wheel 225 and the first transmission shaft 223 may be integrally formed or fixedly connected in a separated manner, and are not particularly limited herein. Further, a first concave surface 2251 is formed on the surface of driver 225, and first concave surface 2251 is engaged with the outer surface of oil pipe 230, so that driver 225 frictionally drives oil pipe 230 to move. It is easy to understand that the arc of the recess of the first concave surface 2251 is adapted to the arc of the outer surface of the oil pipe 230, and during the rotation of the first transmission shaft 223 to drive the driving wheel 225, the first concave surface 2251 rubs against the outer surface of the oil pipe 230, and drives the oil pipe 230 to move by friction. It will be appreciated that the adaptation of the first concave surface 2251 to the outer surface of the oil pipe 230 allows for a larger contact area between the two during the driving process, a higher friction force and a more reliable driving. Optionally, the driving member 221 drives the driving wheel 225 to rotate forward, so that the oil pipe 230 can descend to extend into the bottom of the oil tank 30; the driver 221 rotates the driver 225 in reverse, which raises the oil pipe 230 to be drawn out from the bottom of the oil tank 30.

Oil pipe 230 is clamped between driving wheel 225 and driven wheel 243, oil pipe 230 moves to drive driven wheel 243 to rotate, and encoder 244 is used for measuring the moving distance of oil pipe 230. Optionally, the driven wheel 243 is provided with a second concave surface 2431 on the surface, the curvature of the second concave surface 2431 is matched with the curvature of the outer surface of the oil pipe 230, and the oil pipe 230 is sandwiched between the first concave surface 2251 and the second concave surface 2431. It can be understood that the driving wheel 225 drives the oil pipe 230 to move up and down by friction force, and since there is also friction force between the oil pipe 230 and the driven wheel 243, the oil pipe 230 moves up and down by friction force to drive the driven wheel 243 and the second transmission shaft 242 to rotate, and the encoder 244 on the second transmission shaft 242 can record the number of rotation turns of the driven wheel 243, thereby achieving the purpose of measuring the up and down displacement of the oil pipe 230. The driven assembly 240 is configured to detect the actual lifting displacement of the oil pipe 230, and obtain feedback of the lifting of the oil pipe 230, so as to ensure that the oil pipe 230 extends into the bottom of the oil tank 30 for refueling. The driven wheel 243 and the second transmission shaft 242 may be integrally formed or may be fixedly connected in a separated manner, and this is not particularly limited. In other alternative embodiments, the actual lifting displacement of the oil pipe 230 may be detected by installing a displacement sensor on the oil pipe 230, or other displacement measurement methods may be adopted, which are not specifically limited herein.
Referring to FIG. 6, optionally, a tensioning assembly 250 is coupled to mount 241, and tensioning assembly 250 is configured to move mount 241 away from or toward tubing 230 to adjust the friction between driven wheel 243 and tubing 230, and also to adjust the friction between drive wheel 225 and tubing 230. In this embodiment, the mounting base 241 is provided with a mounting groove 2411, the tensioning assembly 250 includes an adjusting rod 251, a fixing sleeve 252, an elastic member 253, and a limit nut 255, the adjusting rod 251 passes through the fixing sleeve 252 and is in threaded fit with the fixing sleeve 252, one end of the adjusting rod 251 is provided with a mounting portion 254, the mounting portion 254 is connected in the mounting groove 2411 through a fixing member, and the fixing member includes, but is not limited to, a screw or a bolt. The elastic member 253 can be a spring, which is sleeved on the adjusting rod 251 and is abutted between the fixing sleeve 252 and the mounting portion 254 to perform a buffering and adjusting function. The limiting nut 255 is arranged at one end of the fixing sleeve 252 far away from the mounting part 254 and has a limiting effect. Of course, the tensioning assembly 250 and the mounting base 241 may be clamped, welded, riveted, bonded or connected by other methods, which are not limited in particular. In this embodiment, the fixing sleeve 252 is movably connected to the mounting bracket 210, and the mounting bracket 210 is used for limiting the axial movement of the fixing sleeve 252.
During adjustment, the fixing sleeve 252 is rotated in the counterclockwise direction, and since the fixing sleeve 252 is limited by the axial direction of the mounting frame 210, only the fixing sleeve can rotate without moving in the axial direction, the adjusting rod 251 moves backwards relatively, the spring is lengthened, and the adjusting rod 251 can push the mounting seat 241 to move close to the oil pipe 230, so that the friction force between the oil pipe 230 and the driven wheel 243 is increased; as mount 241 continues to move closer to tubing 230, the clamping force of drive wheel 225 and driven wheel 243 on tubing 230 may be increased, i.e., the friction between drive wheel 225 and tubing 230 may be increased, and finally, stop nut 255 may be tightened. Similarly, when the fixing sleeve 252 is rotated clockwise, the adjusting rod 251 moves forward relatively, so that the adjusting rod 251 pushes the mounting base 241 to move away from the oil pipe 230 integrally, and the spring shortens to reduce the friction force between the oil pipe 230 and the driven wheel 243; as mount 241 continues to move away from oil tube 230, the clamping force of drive wheel 225 and driven wheel 243 on oil tube 230 may be reduced, i.e., the frictional force between drive wheel 225 and oil tube 230 is reduced. It can be understood that the tension assembly 250 can adjust the friction force, i.e. the pre-tightening force, between the driven wheel 243 and the oil pipe 230, and between the oil pipe 230 and the driving wheel 225, so that the friction transmission is more reliable, and the oil pipe 230 can be ensured to be effectively lifted. It should be understood that the structure of the tension assembly 250 is not limited thereto, and may be other structures such as screws, threaded rods, push rods or cylinders, as long as the mounting base 241 can move relatively close to or away from the oil pipe 230, and is not limited thereto.
Further, a linear guide 245 is disposed on the mounting frame 210, and the mounting base 241 is disposed on the linear guide 245, so that the tensioning assembly 250 drives the mounting base 241 to move away from or close to the oil pipe 230. In this embodiment, the number of the linear guides 245 is two, and the two linear guides 245 are spaced apart by a distance corresponding to the diameter of the oil pipe 230. The mounting base 241 is arranged on the linear guide 245, so that the driven wheel 243 on the mounting base 241 corresponds to the position of the oil pipe 230, and a pre-positioning function is realized, so as to ensure reliable transmission between the driven wheel 243 and the oil pipe 230. Secondly, when the tensioning assembly 250 drives the mounting base 241 to move close to or away from the oil pipe 230, the mounting base 241 moves along the linear guide rail 245 to play a guiding role, so that the moving precision of the mounting base 241 is improved, and the reliable transmission between the driven wheel 243 and the oil pipe 230 is also ensured.
