[0027] The following is in conjunction with the appendix Figure 1-3 Detailed description: An oil injection pump includes a platform 301, a plurality of oil tanks 402 are provided on the platform 301, an oil pump 405 is provided below the oil tanks 402, and a manual oil injection device and an electric oil injection device are provided on the platform 301.

[0028] The manual oil injection device includes a gearbox 101, a gearbox cover 102 fixedly connected to the gearbox 101, a support shaft I 103 fixedly connected inside the gearbox 101, a push rod I 104 rotatably connected to the support shaft I 103, an opening I 105 on the gearbox cover 102, the push rod I 104 passing through the gearbox cover 102 via the opening I 105, a slide rail 106 fixedly connected inside the gearbox 101, a rack 107 slidably connected to the slide rail 106, a sliding shaft I 109 fixedly connected to the rack 107, a sliding groove I 110 on the push rod I 104, the sliding shaft I 109 slidably connected in the sliding groove I 110, a rotating shaft I 111 rotatably connected to the gearbox 101, a gear I 112 fixedly connected to the rotating shaft I 111, and the gear I 112 meshing with the rack 107.

[0029] Furthermore, when push rod I104 is pushed forward, push rod I104 drives rack 107 to slide forward through sliding shaft I109 and sliding groove I110. Rack 107 drives gear I112 to rotate clockwise. When push rod I104 is pulled backward, push rod I104 drives rack 107 to slide backward through sliding shaft I109 and sliding groove I110. Rack 107 drives gear I112 to rotate. By repeatedly pushing push rod I104, the alternating forward and reverse rotation of rotating shaft I111 can be completed.

[0030] The following is in conjunction with the appendix Figure 4-6In detail, a ratchet disk 201 is fixedly connected to one end of the rotating shaft I111. A pawl disk 202 is rotatably connected to the ratchet disk 201. A ratchet 203 is fixedly connected to the ratchet disk 201. Two pawls 204 are rotatably connected to the pawl disk 202. A torsion spring is fixedly connected between the pawls 204 and the pawl disk 202.

[0031] Furthermore, the torsion spring causes the pawl 204 to engage with the ratchet 203. A retaining spring is provided inside the ratchet disc 201, which ensures that the pawl disc 202 can only rotate within the ratchet disc 201. When the rotating shaft I111 drives the ratchet disc 201 to rotate clockwise, the pawl 204 engages with the ratchet 203, allowing the ratchet disc 201 to drive the pawl disc 202 to rotate clockwise. When the rotating shaft I111 drives the ratchet disc 201 to rotate counterclockwise, the pawl 204 jumps off the ratchet 203, keeping the pawl disc 202 stationary, thus completing the unidirectional rotation of the pawl disc 202.

[0032] The following is in conjunction with the appendix Figure 7-9 In detail, the electric oil injection device includes a reversing box 303, which is fixedly connected to the vehicle plate 301. A reversing box cover 304 is fixedly connected to the reversing box 303. A square shaft 305 is rotatably connected to the reversing box 303. The square shaft 305 is fixedly connected to the input shaft of the oil pump 405. A reversing shaft 306 is slidably connected to the square shaft 305. Bevel gear I 307 and bevel gear II 308 are fixedly connected to both ends of the reversing shaft 306, respectively.

[0033] Furthermore, a square hole is provided at the center of the reversing shaft 306, and the square hole is slidably connected to the square shaft 305, so that the reversing shaft 306 can slide on the square shaft 305, and the square shaft 305 can drive the reversing shaft 306 to rotate.

[0034] The following is in conjunction with the appendix Figure 7-9 In detail, a motor 309 passes through one side of the reversing box 303. The output shaft of the motor 309 is located inside the reversing box 303. A bevel gear III 310 is fixedly connected to the output shaft of the motor 309, and the bevel gear III 310 meshes with the bevel gear I 307. A rotating shaft II 311 is rotatably connected to the reversing box 303. The rotating shaft II 311 is fixedly connected to the ratchet disk 202. A bevel gear IV 312 is fixedly connected to the rotating shaft II 311, and the bevel gear IV 312 can mesh with the bevel gear II 308.

[0035] Furthermore, the motor 309 is fixedly connected to the outside of the bevel gear III 310. The output shaft of the motor 309 passes through the commutator box 303 and is fixedly connected to the bevel gear III 310. When the commutator shaft 306 slides backward, the bevel gear I 307 meshes with the bevel gear III 310. The motor 309 drives the square shaft 305 to rotate through the bevel gear III 310 and the commutator shaft 306. When the commutator shaft 306 slides forward, the bevel gear II 308 meshes with the rotating shaft II 311. The rotating shaft II 311 drives the square shaft 305 to rotate through the rotating shaft II 311 and the commutator shaft 306.

[0036] The following is in conjunction with the appendix Figure 1 In detail, the electric oil injection device also includes a plate 301 and rollers 302. The lower end of the gear box 101 is fixedly connected to the plate 301, and rollers 302 are rotatably connected to the four corners of the plate 301.

[0037] Furthermore, the platform 301 provides support and installation space for the gearbox 101, while the four rollers 302 reduce friction with the ground and facilitate the movement of the oil pump.

[0038] The following is in conjunction with the appendix Figure 7-9 In detail, the electric oil injection device also includes a support shaft II 313, a push rod II 314 and an opening II 315. The upper end of the reversing box cover 304 is fixedly connected to the support shaft II 313, and the push rod II 314 is rotatably connected to the support shaft II 313. The reversing box 303 has an opening II 315, and the push rod II 314 passes through the reversing box 303 through the opening II 315.

[0039] Furthermore, the support shaft II 313 provides support, allowing the push rod II 314 to rotate on the reversing box cover 304.

[0040] The following is in conjunction with the appendix Figure 7-9 In detail, the electric oil injection device also includes a rotating ring 316, a sliding shaft II 317, and a sliding groove II 318. The rotating ring 316 is rotatably connected to the reversing shaft 306. The sliding shaft II 317 is fixedly connected to both ends of the rotating ring 316. The sliding groove II 318 is opened on the push rod II 314, and the sliding shaft II 317 is slidably connected in the sliding groove II 318.

[0041] Furthermore, a rotating groove is provided at the center of the reversing shaft 306, and a rotating ring 316 is rotatably connected in the rotating groove. The rotating groove can limit the rotating ring 316, so that the rotating ring 316 can only rotate on the reversing shaft 306. When the push rod II 314 is pushed forward, the push rod II 314 drives the reversing shaft 306 to slide backward through the sliding shaft II 317 and the sliding groove II 318, so that the bevel gear II 308 meshes with the bevel gear IV 312. When the push rod II 314 is pushed backward, the push rod II 314 drives the reversing shaft 306 to slide forward through the sliding shaft II 317 and the sliding groove II 318, so that the bevel gear I 307 meshes with the bevel gear III 310, thus completing the switch between manual and electric operation.

[0042] The following is in conjunction with the appendix Figure 1 and 10 In detail, the oil pump also includes a bracket 401 and an oil tank 402. Two brackets 401 are fixedly connected to the vehicle plate 301, and an oil tank 402 is fixedly connected to each of the two brackets 401.

[0043] Furthermore, the bracket 401 provides support and installation space for the oil drum 402. The two oil drums 402 can be filled with two different specifications of lubricating oil.

[0044] The following is in conjunction with the appendix Figure 1 and 10 In detail, the oil pump also includes a valve 403 and a connecting pipe 404. The lower ends of the two oil tanks 402 are fixedly connected to the valve 403, and the lower ends of the two valves 403 are fixedly connected to the connecting pipe 404.

[0045] Furthermore, during operation, the two valves 403 are one open and one closed. When the valve 403 on the left is open and the valve 403 on the right is closed, the oil pump outputs lubricating oil from the oil tank 402 on the left. When the valve 403 on the right is open and the valve 403 on the left is closed, the oil pump outputs lubricating oil from the oil tank 402 on the right.

[0046] The following is in conjunction with the appendix Figure 1 and 10 In detail, the oil pump also includes an oil pump 405 and an oil outlet pipe 406. The lower end of the connecting pipe 404 is connected to the oil inlet of the oil pump 405, and the oil outlet of the oil pump 405 is connected to the oil outlet pipe 406.

[0047] Furthermore, the square shaft 305 drives the oil pump 405 to pump out the lubricating oil. When the construction site has power supply, the push rod II 314 is pushed forward, and the motor 309 drives the oil pump 405 to pump oil. When the construction site does not have power supply, the push rod II 314 is pushed backward, and the push rod I 104 is pulled back and forth, so that the oil pump 405 is manually driven to pump oil.

[0048] The working principle of this invention is as follows: When an external power supply is provided at the work site, the motor 309 is connected to the power supply at the work site and pushes the push rod II 314 backward. The push rod II 314 drives the reversing shaft 306 to slide forward through the sliding shaft II 317 and the sliding groove II 318, so that the bevel gear I 307 meshes with the bevel gear III 310. The motor 309 drives the square shaft 305 to rotate through the bevel gear III 310 and the reversing shaft 306. Since the square shaft 305 is fixedly connected to the input shaft of the oil pump 405, the rotation of the square shaft 305 drives the input shaft of the oil pump 405 to rotate, so that the oil pump 405 runs.

[0049] When no external power supply is provided at the work site, push the push rod II 314 forward. Push rod II 314 drives the reversing shaft 306 to slide backward through sliding shaft II 317 and sliding groove II 318, causing bevel gear II 308 to engage with bevel gear IV 312. Then, push the push rod I 104 back and forth. Push rod I 104 drives the rack 107 to slide backward through sliding shaft I 109 and sliding groove I 110. The rack 107 drives gear I 112 to rotate. Gear I 112 drives rotating shaft I 111 to rotate. Rotating shaft I 111 rotates through a ratchet pawl. 204 and ratchet 203 drive the pawl disc 202 to rotate in one direction. Since the pawl disc 202 is fixedly connected to the rotating shaft II 311, the rotation of the pawl disc 202 drives the rotating shaft II 311 to rotate. The rotating shaft II 311 drives the bevel gear IV 312, which is fixedly connected to it, to rotate. The bevel gear IV 312 drives the bevel gear II 308, which meshes with it, to rotate. The bevel gear II 308 drives the square shaft 305 to rotate through the reversing shaft 306. When the square shaft 305 rotates, it drives the input shaft of the oil pump 405 to rotate, thus making the oil pump 405 run.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
