Description

[0001] This application is a divisional application of the application with the application date of December 4, 2021, the application number of 202111602178X, and the application title of "Fuel injection device for cooperating with manipulator operation". Technical Field

[0002] The present invention relates to the field of nuclear industry production auxiliary equipment, and in particular to a fuel injection device for cooperating with manipulator operation. Background Art

[0003] In a nuclear radiation environment, the key transmission parts of equipment in a sealed chamber need to be lubricated and maintained regularly to avoid problems such as corrosion, fracture, pitting, gluing, and jamming of transmission parts, which will affect the use accuracy and service life of the equipment. At present, the refueling and lubrication of equipment in a radiation-sealed chamber mainly rely on manual operation while wearing heavy inflatable protective clothing, and there is no automated operation equipment.

[0004] There are two existing refueling devices, one is electric and the other is manual. Neither the manual device nor the electric device can be operated by a manipulator. The manual device is inconvenient for manual operation while wearing protective clothing, and the radiation hazard is relatively large to the human body; the motor and circuit board of the electric device do not have radiation resistance function, are extremely prone to failure, and the mobile power supply and battery are not allowed to enter the radiation-sealed chamber. In summary, the existing refueling devices cannot meet the use conditions in the sealed chamber. Summary of the Invention

[0005] The present invention aims at the above problems and provides a fuel injection device for cooperating with manipulator operation.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A fuel injection device for cooperating with manipulator operation includes a push rod, a frame, a manipulator cooperation part, a ratchet bar, a push piece and a spring piece. The push rod is slidably arranged on the frame, the manipulator cooperation part is slidably arranged on the frame, the ratchet bar is fixed on the push rod, one end of the push piece is hinged to the manipulator cooperation part, the other end of the push piece abuts against the ratchet bar, one end of the spring piece is fixed on the manipulator cooperation part, the other end of the spring piece abuts against the push piece, and a mechanical finger ring is arranged on the manipulator cooperation part.

[0008] In this fuel injection device, the function of the ratchet bar and the push piece is to push the push rod to move. When the manipulator cooperation part moves, the push piece squeezes the ratchet bar on the push rod, so that the push rod moves towards the side of the fixed end cover. The function of the spring piece is to spring the push piece towards the ratchet bar, so that one end of the push piece always has a tendency to abut against the ratchet bar. Therefore, when using this device, only need to insert the manipulator into the mechanical finger ring, so that the manipulator can drive the manipulator cooperation part to move on the frame, and the movement of the manipulator cooperation part can drive the push rod to move. Thus, when there is an oil bottle on one side of the push rod, the push rod can squeeze the oil bottle to achieve oil output.

[0009] In summary, this device only needs to cooperate with a manipulator to utilize the manipulator for operation. There is no need for manual entry into the radiation environment, and the operation is convenient and highly reliable.

[0010] Optionally, the mechanical finger ring includes a convex mechanical finger ring and a concave mechanical finger ring.

[0011] Specifically, the convex mechanical finger ring and the concave mechanical finger are respectively located on both sides of the manipulator mating part, which is more conducive to the manipulator operating and moving the manipulator mating part.

[0012] Optionally, it further includes a pressure rod and a pressure plate. The pressure rod is slidably arranged on the frame, and the pressure plate is fixed on the pressure rod.

[0013] The specific function of the pressure rod is to drive the pressure rod towards the push piece when it is necessary to separate the push piece from the ratchet bar. Under the extrusion of the pressure rod, the push piece disengages from the cooperation with the ratchet bar, and the push rod can move freely. Specifically, in order to ensure that the pressure rod can automatically reset after extrusion, a spring is sleeved on the pressure rod. One end of the spring abuts against the pressure plate, and the other end of the spring abuts against the frame. The spring is used to drive the pressure rod that has been extruded and moved to reset. Specifically, there are two pressure rods, and each of the two pressure rods is respectively used to extrude a push piece.

[0014] Optionally, a guide rail is arranged on the frame, and the manipulator mating part is slidably sleeved on the guide rail.

[0015] The function of setting the guide rail is to enable the manipulator mating part to slide along the guide rail. Specifically, a linear bearing is arranged on the manipulator mating part, and the guide rail passes through the linear bearing on the manipulator mating part.

[0016] Optionally, it further includes a spring, and the spring is sleeved on the guide rail.

[0017] The function of the spring is to drive the moved manipulator mating part to automatically return to its original position. Specifically, the spring is sleeved on the guide rail. One end of the spring on the guide rail abuts against the manipulator mating part, and the other end of the spring abuts against the middle partition on the frame. In this way, the spring can drive the manipulator mating part to rebound to its original position after the manipulator mating part slides. Specifically, the middle partition is a hollow plate formed by splicing two plates together. The push rod passes through the middle partition, and the middle partition divides the frame equally.

[0018] Optionally, it further includes a positioning ball pin. The positioning ball pin is arranged on the frame, and a positioning pit for cooperating with the positioning ball pin is arranged on the push rod.

[0019] The cooperation between the positioning ball pin and the positioning pit is to position the push rod and prevent the push rod from rebounding after being extruded and moved by the manipulator mating part.

[0020] Optionally, it further includes a gear and a rack. The gear is rotatably mounted on the frame, and the rack is disposed on the manipulator mating portion. The rack meshes with the gear.

[0021] Specifically, there are two manipulator mating portions. A rack is installed on each manipulator mating portion, and the racks on the two manipulator mating portions mesh with the gear. Such a design is to link the two manipulator mating portions to ensure that the manipulator mating portions are more stable when moving.

[0022] Optionally, push plates and handles are respectively provided at both ends of the push rod.

[0023] The function of the push plate on the push rod is to contact the movable end cap, so that the push rod can stably push the movable end cap, and the handle is convenient for the operator to pull the push rod.

[0024] Optionally, it further includes a cylinder body, a fixed end cap and a movable end cap. The cylinder body is detachably fitted with the frame. The fixed end cap is detachably fixed to one end of the cylinder body, and the movable end cap is slidably disposed in the cylinder body.

[0025] Specifically, a rotary engagement groove is provided on the frame of this device. The cylinder body is rotationally engaged with the rotary engagement groove of the frame. By rotating the cylinder body, the cylinder body can be detached from or assembled onto the frame.

[0026] At the same time, the fixed end cap and the cylinder body of this device are fitted together by means of threaded connection. A hexagonal square head is provided on the fixed end cap. When disassembly is required, only need to use a wrench to turn the hexagonal square head, and the fixed end cap can be detached from the cylinder body.

[0027] It should be noted that the movable end cap, the fixed end cap and the cylinder body form a relatively sealed environment. The movable end cap can prevent the oil bottle from being centered when being squeezed, avoiding jamming of the equipment.

[0028] The usage process of this device is as follows. First, place the oil bottle into the cylinder body. The cylinder body is made of stainless steel, and the stainless steel cylinder body can prevent radiation. When in use, the manipulator can be inserted into the manipulator finger ring, so that the manipulator can drive the manipulator mating portion to move through the manipulator finger ring. The movement of the manipulator mating portion can drive the push rod to move, and the movement of the push rod can drive the movable end cap to squeeze the oil bottle to squeeze out the oil in the oil bottle.

[0029] Optionally, it further includes a valve and a universal elbow. The valve is disposed on the fixed end cap. The universal elbow is disposed on the valve, and a nozzle is provided on the universal elbow.

[0030] The valve can adjust the oil output according to the usage requirements. The universal curved pipe can adjust the oil output direction as needed. Before use, the valve and the orientation of the universal curved pipe can be adjusted through the glove box. After use, the valve can be closed through the glove box operation.

[0031] The beneficial effects of the present invention are as follows: It only needs to cooperate with the manipulator to utilize the manipulator for operation, without the need for manual entry into the radiation environment, with convenient operation and strong reliability.

Detailed Embodiment

[0037] The present invention will be described in detail below in conjunction with each drawing.

[0038] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a filling device for cooperating with the manipulator operation includes a push rod 10, a frame 6, a manipulator cooperation part 7, a ratchet bar 1002, a push piece 13 and an elastic piece 17. The push rod 10 is slidably arranged on the frame 6. The manipulator cooperation part 7 is slidably arranged on the frame 6. The ratchet bar 1002 is fixed on the push rod 10. One end of the push piece 13 is hinged to the manipulator cooperation part 7. The other end of the push piece 13 abuts against the ratchet bar 1002. One end of the elastic piece 17 is fixed on the manipulator cooperation part 7. The other end of the elastic piece 17 abuts against the push piece 13. A mechanical finger ring is arranged on the manipulator cooperation part 7.

[0039] In this oil filling device, the function of the ratchet 1002 and the push piece 13 is to push the push rod 10 to move. When the manipulator matching part 7 moves, the push piece 13 squeezes the ratchet 1002 on the push rod 10, so that the push rod 10 moves to the side of the fixed end cover 4. The function of the spring 17 is to bounce the push piece 13 to the ratchet 1002, so that one end of the push piece 13 always has a tendency to resist the ratchet 1002. Therefore, when using this device, you only need to insert the manipulator into the manipulator finger ring, so that the manipulator can drive the manipulator matching part 7 to move on the frame 6, and the movement of the manipulator matching part 7 can drive the push rod 10 to move. In this way, when there is an oil bottle on one side of the push rod 10, the push rod 10 can squeeze the oil bottle to achieve oil discharge.

[0040] In summary, the device only needs to be coordinated with a manipulator to be operated by the manipulator, and there is no need for humans to enter the radiation environment. It is easy to operate and has high reliability.

[0041] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, the mechanical finger ring includes an outer convex mechanical finger ring 701 and an inner concave mechanical finger ring 702.

[0042] Specifically, the outward convex robot finger ring 701 and the inward concave robot finger ring 702 are respectively located on both sides of the robot arm matching part 7, which is more conducive to the robot arm operating the moving robot arm matching part 7.

[0043] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, it also includes a pressing rod 12 and a pressing plate 11 . The pressing rod 12 is slidably arranged on the frame 6 , and the pressing plate 11 is fixed on the pressing rod 12 .

[0044] The specific function of the pressure rod 12 is to drive the pressure rod 12 to move toward the push piece 13 when it is necessary to disengage the push piece 13 from the ratchet 1002. Under the extrusion of the pressure rod 12, the push piece 13 disengages from the ratchet 1002, and the push rod 10 can move freely. Specifically, in order to ensure that the pressure rod 12 can automatically reset after being squeezed, a spring is sleeved on the pressure rod 12, one end of the spring abuts against the pressure plate 11, and the other end of the spring abuts against the frame 6. The spring is used to drive the pressure rod 12 to reset after being squeezed and moved. Specifically, there are two pressure rods 12, and the two pressure rods 12 are used to squeeze a push piece 13 respectively.

[0045] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 As shown, a guide rail 8 is provided on the frame 6 , and the manipulator matching part 7 is slidably sleeved on the guide rail 8 .

[0046] The function of the guide rail 8 is to allow the manipulator mating part 7 to slide along the guide rail 8. Specifically, a linear bearing is provided on the manipulator mating part 7, and the guide rail 8 passes through the linear bearing on the manipulator mating part 7.

[0047] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, it also includes a spring (not shown in the attached drawings), and the spring is sleeved on the guide rail 8.

[0048] The function of the spring is to drive the moved manipulator mating part 7 to automatically return to its original position. Specifically, the spring is sleeved on the guide rail 8. One end of the spring on the guide rail 8 abuts against the manipulator mating part 7, and the other end of the spring abuts against the middle partition plate 601 on the frame 6. In this way, the spring can drive the manipulator mating part 7 to rebound to its original position after the manipulator mating part 7 slides. Specifically, the middle partition plate 601 is a hollow plate formed by splicing two plates, and the push rod 10 passes through the middle partition plate 601, and the middle partition plate 601 divides the frame 6 into equal parts.

[0049] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, it also includes a positioning ball pin 9. The positioning ball pin 9 is arranged on the frame 6, and a positioning pit 1001 for cooperating with the positioning ball pin 9 is arranged on the push rod 10.

[0050] The cooperation between the positioning ball pin 9 and the positioning pit 1001 is to position the push rod 10 and prevent the push rod 10 from rebounding after being squeezed and moved by the manipulator mating part 7.

[0051] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, it also includes a gear and a rack. The gear is rotatably installed on the frame 6, and the rack is arranged on the manipulator mating part 7, and the rack is meshed with the gear.

[0052] Specifically, there are two manipulator mating parts 7, and the two manipulator mating parts are respectively located on both sides of the middle partition plate 601. A rack is installed on each manipulator mating part 7, and the racks on the two manipulator mating parts 7 are both meshed with the gear. This design is to link the two manipulator mating parts 7 and ensure that the manipulator mating part 7 is more stable when moving.

[0053] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, push plates and a handle 14 are respectively arranged at both ends of the push rod 10.

[0054] The function of the push plate on the push rod 10 is to contact the movable end cap 16, so that the push rod 10 can stably push the movable end cap 16, and the handle 14 is convenient for the operator to pull the push rod 10.

[0055] As shown in the attached Figure 1 , attached Figure 2 , attached Figure 3 and attached Figure 4 As shown, it also includes a cylinder body 5, a fixed end cap 4 and a movable end cap 16. The cylinder body 5 is detachably fitted with the frame 6, the fixed end cap 4 is detachably fixed at one end of the cylinder body 5, and the movable end cap 16 is slidably arranged inside the cylinder body 5.

[0056] Specifically, a rotary engagement groove 602 is provided on the frame 6 of the device. The cylinder body 5 is rotationally engaged with the rotary engagement groove 602 of the frame 6. By rotating the cylinder body 5, the cylinder body 5 can be detached from or assembled onto the frame 6.

[0057] At the same time, the fixed end cap 4 of the device is fitted with the cylinder body 5 by means of a threaded connection. A hexagonal square head is provided on the fixed end cap 4. When disassembly is required, only by using a wrench to turn the hexagonal square head can the fixed end cap 4 be detached from the cylinder body 5.

[0058] It should be noted that the movable end cap 16, the fixed end cap 4 and the cylinder body 5 form a relatively sealed environment. The movable end cap 16 can prevent the oil bottle from being centered when being squeezed, and avoid the equipment from getting stuck.

[0059] The usage process of this device is as follows. First, place the oil bottle into the cylinder body 5. The cylinder body 5 is a cylinder body 5 made of stainless steel. The stainless steel cylinder body 5 can prevent radiation. When in use, the manipulator can be inserted into the manipulator finger ring, so that the manipulator can drive the manipulator mating part 7 to move through the manipulator finger ring. The movement of the manipulator mating part 7 can drive the push rod 10 to move. The movement of the push rod 10 can drive the movable end cap 16 to squeeze the oil bottle and squeeze out the oil in the oil bottle 20.

[0060] As shown in the attached Figure 1 , attached Figure 2 , attached Figure 3 attached Figure 4 As shown, it also includes a valve 3 and a universal elbow 2. The valve 3 is arranged on the fixed end cap 4, the universal elbow 2 is arranged on the valve 3, and a nozzle 1 is arranged on the universal elbow 2.

[0061] The valve 3 can adjust the oil output according to the usage needs. The universal elbow 2 can adjust the oil output direction according to the needs. Before use, the orientation of the valve 3 and the universal elbow 2 can be adjusted through the glove box. After use, the valve 3 can be operated to close through the glove box.

[0062] Specifically, in this embodiment, the cylinder body 5 is made of radiation-resistant material, which can be stainless steel, tin bronze, aluminum alloy, titanium alloy or lead.

[0063] In this embodiment, the manipulator mating part 7 is formed by splicing two plates, and in other embodiments, an integral manipulator mating part can also be used.

[0064] In this embodiment, the frame 6 is formed by splicing several plates together, and the frame is generally rectangular.

[0065] Refer to the attached Figure 1 ~the attached Figure 4 , and the usage method of this device will be further described in detail.

[0066] First, rotate the cylinder body 5 to disassemble the cylinder body 5 from the frame 6, take out the movable end cap 16, then insert the oil bottle 15 into the cylinder body 5, connect the oil bottle to the valve 15, then place the movable end cap 16 into the cylinder body 5 again, and then install the cylinder body 5 onto the frame 6. Then, use the manipulator to squeeze and move the two manipulator mating parts 7. When the manipulator mating part 7 approaches the push rod 10, the push piece 13 starts to squeeze the ratchet 1002 on the push rod 10. Under the pushing and squeezing of the push piece 13, the push rod 10 continuously moves into the cylinder body 5. The push rod 10 drives the movable end cap 16 to move, and the oil bottle 15 is continuously squeezed. The oil in the oil bottle 15 flows out through the nozzle 1.

[0067] During the oil outlet process, the manipulator opens to drive the manipulator mating part 7 to open. The push rod 10 remains stationary under the locking action of the positioning ball pin 9 and the positioning pit 1001. The push piece 13 is reset under the action of the elastic piece 17 and snaps into the card slot at the upper end of the ratchet 1002, and pushes the push rod 10 to discharge oil when squeezing again.

[0068] When the oil in the oil bottle 15 is used up, press the pressing plate 11. The pressing plate 11 drives the pressing rod 12 to squeeze the push piece 13. The push piece is disengaged from the ratchet 1002. Then, the push rod 10 can be pulled out of the cylinder body 5 through the handle 14. Release the pressing plate 11, and the pressing rod 12 rebounds and resets under the action of the spring (not shown) sleeved on the pressing rod 12. Disassemble the cylinder body 5 to replace the new oil bottle for the next extrusion operation.

[0069] It should be noted that this kind of filling device can not only be used to squeeze out oil, but also be used to extrude other liquids or ointments.

[0070] The above are only the preferred embodiments of the present invention, and thus do not limit the patent protection scope of the present invention. Any equivalent transformation made by using the description of the present invention, directly or indirectly applied in other related technical fields, shall be included in the protection scope of the present invention by the same token.
