Description

Technical Field

[0001] This utility model relates to the technical field of oil injection devices, specifically to a manual sensing oil injection device. Background Technology

[0002] During use, the shaft and bushing of a track chain will wear due to friction. To reduce friction between the shaft and bushing and extend the service life of the track chain, a certain amount of lubricating grease should be added between the shaft and bushing before installation.

[0003] A search revealed an invention patent with publication number CN107477343 B, which discloses an oil injection device. The device includes a clamping mechanism and an oil injection mechanism. The clamping mechanism comprises a clamping seat and a clamping cover. The clamping cover and clamping seat cooperate to clamp the shaft sleeve and both ends of the shaft. The clamping seat has an oil injection port for injecting oil between the shaft and the shaft sleeve. The oil injection mechanism includes an oil tank and an oil injection power component. The oil injection power component is connected to the oil injection port via an oil passage and is used to output the lubricating oil from the oil tank through the oil passage. The oil injection device provided by this invention only requires placing the assembled shaft and shaft sleeve between the clamping seat and the clamping cover. The clamping cover and clamping seat cooperate to clamp the two ends of the shaft and shaft sleeve. Then, the oil injection power component is activated, outputting the lubricating oil from the oil tank through the oil passage and injecting it into the space between the shaft and shaft sleeve through the oil injection port, thereby achieving automatic oil injection. This method is highly efficient, provides uniform and controllable oil volume, and ensures even distribution of grease between the shaft and shaft sleeve.

[0004] Although the aforementioned patent achieves automatic lubrication by placing the assembled shaft and bushing between the clamping seat and the clamping cover, with the clamping cover and clamping seat clamping the two ends of the shaft and bushing, and then activating the oil injection power unit to output the lubricating oil in the oil tank through the oil passage and inject it into the shaft and bushing from the oil injection port, thus achieving high working efficiency and uniform and controllable oil volume, ensuring even distribution of grease between the shaft and bushing, different types or sizes of shafts and bushings require different amounts of oil. Therefore, it is necessary to adjust the oil output from the oil injection port. Furthermore, the lubricating oil is significantly affected by temperature and pressure in the oil pipe. When the lubricating oil flows easily in the oil pipe, changes in temperature or pressure can easily cause large gaps between the lubricating oil, resulting in uneven oil output from the oil injection port, which in turn affects the distribution of grease on the surface of the shaft and bushing.

[0005] Therefore, it is necessary to propose a manual induction oil injection device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a manual sensing oil injection device. By adjusting the cooperation between the internal parts of the adjustment mechanism, it is easy to manually adjust the amount of oil flowing out of the oil injection pipe. At the same time, when a large gap occurs between the lubricating oil flowing inside the oil injection pipe, an alarm will be sounded to remind the surrounding personnel. Through the cooperation between the internal parts of the oil replenishment mechanism, when the amount of oil flowing out of the oil injection pipe decreases, the oil replenishment pipe will replenish the oil, thereby ensuring the uniform distribution of grease and the amount of oil injected on the surface of the shaft and bearing. This solves the problem in the prior art that different types or sizes of shafts and bushings require different amounts of oil, thus requiring adjustment of the oil output at the oil injection port.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a manual sensing oil injection device, including an oil injection pipe, a connecting bracket mechanically fixed to the outer wall of the oil injection pipe, an adjusting mechanism rotatably connected to the outer wall of the oil injection pipe and extending into the interior of the oil injection pipe, and an oil replenishing mechanism mechanically fixed to the top and bottom ends of the connecting bracket, located on the right side of the oil injection pipe and extending into the interior of the oil injection pipe;

[0008] The adjustment mechanism includes an infrared sensor, which is bolted to both sides of the inner wall of the oil injection pipe and extends into the interior of the connecting bracket. A microcontroller terminal is bolted inside the connecting bracket and connected to the infrared sensor signal via a cable. An alarm component is threaded to the top of the connecting bracket and connected to the microcontroller terminal signal via a cable, and is located on the left side of the oil injection pipe.

[0009] The oil replenishment mechanism includes an oil replenishment pipe located to the right of the oil injection pipe and extending through the oil injection pipe to the bottom of the connecting bracket. A sealing partition is slidably connected to the inner wall of the oil injection pipe at the connection point with the oil replenishment pipe. A support shaft is mechanically connected to the bottom end of the sealing partition. A limit slider is mechanically connected to the bottom end of the support shaft and slidably connected inside the oil injection pipe. An electromagnet is bolted to the inner wall of the oil injection pipe and located below the limit slider. A telescopic spring is mechanically connected between the top end of the electromagnet and the bottom end of the limit slider.

[0010] Preferably, the adjusting mechanism further includes an adjusting ring, which is rotatably connected to the outer wall of the oil injection pipe. A bevel gear ring is mechanically fixed to the inner wall of the adjusting ring and rotatably connected to the inside of the oil injection pipe. A bevel gear is rotatably connected to the inside of the oil injection pipe and is located on one side of the bevel gear ring. A connecting shaft is mechanically fixed to the right side of the bevel gear and rotatably connected to the inside of the oil injection pipe. A sealing plate is mechanically fixed to the side of the connecting shaft away from the bevel gear and is sealed to the inner wall of the oil injection pipe.

[0011] Preferably, the top of the alarm component includes a buzzer and a warning light, and the inside of the connecting bracket is equipped with a battery module that drives the microcontroller terminal, the alarm component, the infrared sensor, and the electromagnet.

[0012] Preferably, the outer wall of the oil injection pipe is provided with a rotating groove that matches the adjusting ring, and the top of the adjusting ring is provided with elastic blocks in annular shape. The bevel gear ring and the bevel gear mesh with each other through the tooth groove, and the inner wall of the oil injection pipe is provided with a sealing groove that matches the sealing plate.

[0013] Preferably, the bottom end of the oil replenishment pipe is at the same horizontal level as the bottom end of the oil injection pipe, and the bottom end of the oil injection pipe is rotatably connected with a ball bearing. The surface of the sealing partition is provided with an oil delivery hole that matches the oil replenishment pipe, and the diameter of the oil replenishment pipe is smaller than that of the oil injection pipe.

[0014] Preferably, the inside of the oil injection pipe is provided with a barrier groove that matches the sealing partition, and the inside of the oil injection pipe is provided with a sliding groove that matches the limiting slider. The bottom end of the limiting slider is fixed with a magnet that attracts an electromagnet through magnetism.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By rotating the adjusting ring, the adjusting ring slowly rotates on the outer wall of the oil injection pipe through the elastic block. The rotation of the adjusting ring drives the bevel gear ring to rotate, which in turn drives the bevel gear to rotate. The rotation of the bevel gear drives the connecting shaft to rotate, which in turn drives the sealing plate to rotate. The rotation of the sealing plate can adjust the amount of oil inside the oil injection pipe. When the lubricating oil inside the oil injection pipe has gaps between the greases due to temperature or pressure changes, the infrared sensors can emit signals to each other due to the gaps in the greases as the lubricating oil flows through the oil injection pipe. This will transmit the signals to the microcontroller terminal, which will then control the alarm component to sound an alarm and alert nearby personnel.

[0017] 2. By creating a gap between the greases inside the oil injection pipe and triggering an alarm, the microcontroller terminal simultaneously energizes the electromagnet. The energized electromagnet magnetically attracts the limit slider, which, under pressure, compresses the telescopic spring and moves downwards. This movement of the limit slider moves the support shaft, which in turn moves the sealing partition at the top. This releases the seal between the oil replenishment pipe and the oil injection pipe. Since the diameter of the oil replenishment pipe is smaller than that of the oil injection pipe, the grease in the oil injection pipe flows into the oil replenishment pipe and drips from inside the oil replenishment pipe onto the surfaces of the shaft and bearing, thus completing the grease replenishment operation on the surfaces of the shaft and bearing.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6 The manual induction oil filling device shown includes an oil filling pipe 1, a connecting bracket 101 mechanically fixed to the outer wall of the oil filling pipe 1, an adjusting mechanism 2 rotatably connected to the outer wall of the oil filling pipe 1 and extending into the interior of the oil filling pipe 1, and an oil replenishing mechanism 3 mechanically fixed to the top and bottom ends of the connecting bracket 101, located on the right side of the oil filling pipe 1 and extending into the interior of the oil filling pipe 1.

[0029] The adjustment mechanism 2 includes an infrared sensor 207, which is bolted to both sides of the inner wall of the oil injection pipe 1 and extends into the interior of the connecting bracket 101. A microcontroller terminal 206 is bolted inside the connecting bracket 101 and is connected to the infrared sensor 207 via a cable. An alarm component 208 is threaded to the top of the connecting bracket 101 and is connected to the microcontroller terminal 206 via a cable, and is located on the left side of the oil injection pipe 1.

[0030] The oil replenishment mechanism 3 includes an oil replenishment pipe 301, which is located on the right side of the oil injection pipe 1 and extends through the oil injection pipe 1 to the bottom end of the connecting bracket 101. A sealing partition 306 is slidably connected to the inner wall of the oil injection pipe 1 at the connection point with the oil replenishment pipe 301. A support shaft 305 is mechanically connected to the bottom end of the sealing partition 306. A limit slider 304 is mechanically connected to the bottom end of the support shaft 305 and is slidably connected inside the oil injection pipe 1. An electromagnet 302 is bolted to the inner wall of the oil injection pipe 1 and is located below the limit slider 304. A telescopic spring 303 is mechanically connected between the top end of the electromagnet 302 and the bottom end of the limit slider 304.

[0031] By adjusting the cooperation between the internal parts of the adjustment mechanism 2, it is easy to manually adjust the amount of oil output inside the oil injection pipe 1. At the same time, when a large gap is generated between the lubricating oil flowing inside the oil injection pipe 1, an alarm will be sounded to remind the surrounding personnel. By adjusting the cooperation between the internal parts of the oil replenishment mechanism 3, when the amount of oil output inside the oil injection pipe 1 decreases, the oil replenishment pipe 301 will replenish the oil, thereby ensuring the uniform distribution of grease and the amount of oil injected on the surface of the shaft and bearing.

[0032] Refer to the instruction manual appendix Figure 1-6 The adjusting mechanism 2 also includes an adjusting ring 201, which is rotatably connected to the outer wall of the oil injection pipe 1. A bevel gear ring 202 is mechanically fixed to the inner wall of the adjusting ring 201 and rotatably connected to the inside of the oil injection pipe 1. A bevel gear 203 is rotatably connected to the inside of the oil injection pipe 1 and is located on one side of the bevel gear ring 202. A connecting shaft 204 is mechanically fixed to the right side of the bevel gear 203 and rotatably connected to the inside of the oil injection pipe 1. A sealing plate 205 is mechanically fixed to the side of the connecting shaft 204 away from the bevel gear 203 and is sealed to the inner wall of the oil injection pipe 1. When a large gap is generated between the lubricating oil flowing inside the oil injection pipe 1 due to the mutual cooperation between the internal parts of the adjusting mechanism 2, an alarm will be sounded to remind the surrounding personnel.

[0033] Refer to the instruction manual appendix Figure 1-6The alarm component 208 has a buzzer and a warning light at its top. The connecting bracket 101 has a battery module installed inside to drive the microcontroller terminal 206, the alarm component 208, the infrared sensor 207, and the electromagnet 302. The alarm component 208 has a buzzer and a warning light at its top, which can be used to alert the surrounding staff.

[0034] Refer to the instruction manual appendix Figure 1-6 The outer wall of the oil injection pipe 1 is provided with a rotating groove that matches the adjusting ring 201, and the top of the adjusting ring 201 is provided with elastic blocks in an annular shape. The bevel ring 202 and the bevel gear 203 mesh with each other through the tooth groove. The inner wall of the oil injection pipe 1 is provided with a sealing groove that matches the sealing plate 205. The bevel ring 202 and the bevel gear 203 mesh with each other through the tooth groove. The inner wall of the oil injection pipe 1 is provided with a sealing groove that matches the sealing plate 205, so that the bevel gear 203 can rotate and drive the sealing plate 205 to rotate through the connecting shaft 204.

[0035] Refer to the instruction manual appendix Figure 1-6 The bottom end of the oil replenishing pipe 301 is at the same horizontal level as the bottom end of the oil injection pipe 1, and the bottom end of the oil injection pipe 1 is rotatably connected with a ball bearing. The surface of the sealing partition 306 is provided with an oil supply hole that matches the oil replenishing pipe 301. The diameter of the oil replenishing pipe 301 is smaller than that of the oil injection pipe 1. The oil supply hole provided on the surface of the sealing partition 306 makes it easy for lubricating oil to flow into the interior of the oil replenishing pipe 301 through the oil supply hole on the surface of the sealing partition 306.

[0036] Refer to the instruction manual appendix Figure 1-6 The oil injection pipe 1 has a barrier groove inside that matches the sealing partition 306. The oil injection pipe 1 also has a sliding groove inside that matches the limiting slider 304. A magnet is fixed at the bottom of the limiting slider 304 and is attracted to the electromagnet 302 by magnetism. This allows the limiting slider 304 to slide by magnetism after the electromagnet 302 is energized.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-6By rotating the adjusting ring 201, the adjusting ring 201 slowly rotates on the outer wall of the oil injection pipe 1 via the elastic block. The rotation of the adjusting ring 201 drives the bevel gear ring 202 to rotate, which in turn drives the bevel gear 203 to rotate. The rotation of the bevel gear 203 drives the connecting shaft 204 to rotate, which in turn drives the sealing plate 205 to rotate. The rotation of the sealing plate 205 can adjust the amount of oil inside the oil injection pipe 1. When the lubricating oil inside the oil injection pipe 1 has gaps between the greases due to temperature or pressure changes, and the lubricating oil flows from inside the oil injection pipe 1, the infrared sensors 207 can emit signals to each other due to the gaps in the greases. This will transmit the signal to the microcontroller terminal 206, which will then control the alarm component 208 to sound an alarm and alert the surrounding personnel.

[0039] Refer to the instruction manual appendix Figure 1-6 When a gap is created between the greases inside the oil injection pipe 1 and the alarm component 208 sounds an alarm, the microcontroller terminal 206 simultaneously energizes the electromagnet 302. The energized electromagnet 302 magnetically attracts the limiting slider 304. The limiting slider 304 is forced to compress the telescopic spring 303 and moves downward. The movement of the limiting slider 304 drives the support shaft 305 to move. The movement of the support shaft 305 drives the sealing partition 306 at the top to move, causing the sealing partition 306 to release the seal between the oil replenishment pipe 301 and the oil injection pipe 1. Since the diameter of the oil replenishment pipe 301 is smaller than that of the oil injection pipe 1, the grease in the oil injection pipe 1 flows into the oil replenishment pipe 301 and drips from inside the oil replenishment pipe 301 onto the surface of the shaft and bearing, thus completing the grease replenishment operation on the surface of the shaft and bearing.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
