Description

Technical Field

[0001] This utility model relates to the technical field of bearing oil injection devices, and in particular to a portable bearing oil injection device. Background Technology

[0002] During operation, the relative motion between the various components of a bearing inevitably leads to friction. Friction generates heat, and excessively high temperatures can severely affect the bearing's performance and lifespan. Prolonged operation can cause bearing components to loosen, resulting in noise and vibration. In humid or corrosive environments, bearings are susceptible to corrosion and rust. Adding lubricating oil is often a necessary means of bearing maintenance to protect the bearing, make it run more flexibly, and extend its service life.

[0003] In railway vehicle maintenance, a large number of bearings require lubrication. Currently, lubrication is done using grease guns or automatic grease injection devices. An existing patent (publication number: CN220669132U) discloses a lubricating grease filling device, including an oil tank and a vibrating pressure plate that is lifted and installed inside the oil tank. The vibrating pressure plate and the oil tank are positioned to form a variable volume oil chamber. The oil pump's suction pipe passes through the vibrating pressure plate and extends into the oil chamber. The liftable vibrating pressure plate slides in conjunction with the suction pipe. When the oil pump is pumping oil, the lubricating grease in the oil chamber is lowered by the vibrating pressure plate.

[0004] Existing patents offer solutions to the above problems, but the oil gun requires continuous replenishment of melted oil to complete the oiling process. While automatic oiling devices can solve the problem of continuous oil replenishment, they are bulky and inconvenient to move on railway tracks.

[0005] Therefore, a portable bearing oil injection device is proposed. Utility Model Content

[0018] Please see Figure 1-4 The present invention provides the following technical solution: A portable bearing oiling device includes a base 7, an oil pipe 2, a mobile power supply 3, a grease pump 1, a spring hose 41, an oil gun 4, and a controller 6. The grease pump 1, the power supply compartment 31, and the oil pipe 2 holder are all located on the top of the base 7. The oil pipe 2 is detachably fixed to the oil pipe 2 holder. The mobile power supply 3 is detachably fixed inside the power supply compartment 31. The oil pipe 2 holder is connected to the grease pump 1 through a connecting pipe 8. The controller 6 is connected to the power supply compartment 31. A flow meter 5 and a valve 81 are respectively installed on the connecting pipe 8. The grease pump 1 is connected to the oil gun 4 through the spring hose 41.

[0019] In this embodiment, the use is greatly facilitated by the detachable and replaceable oil pipe 2 and the detachable mobile power supply 3. The grease pump 1, oil pipe 2 and mobile power supply 3 are integrated on the base 7 and a handle is provided for easy movement and carrying. The oil gun 4 is connected to the grease pump 1 through a spring hose 41, which greatly reduces the burden during use and improves the working efficiency of bearing lubrication.

[0020] Specifically, such as Figure 1 As shown, the grease pump 1 and the flow meter 5 are connected to the power output terminal of the controller 6, the output signal of the flow meter 5 is connected to the signal input terminal of the controller 6, and the control output terminal of the controller 6 is connected to the control input terminal of the grease pump 1.

[0021] Specifically, such as Figure 1As shown, valve 81 is installed on the connecting pipe 8 near the oil pipe 2 seat, and flow meter 5 is installed on the connecting pipe 8 near the grease pump 1.

[0022] In this embodiment: by setting valve 81, valve 81 can be closed when oil pipe 2 is replaced to prevent air from entering the connecting pipe 8; flow meter 5 is used to measure the flow rate of the set grease and transmit the measurement signal to controller 6 to control the start and stop of grease pump 1.

[0023] Specifically, such as Figure 1 As shown, a carrying bracket 73 is provided on the top of the base 7, and supports 71 are provided at the four corners of the bottom of the base 7. A height adjustment block 72 is provided at the bottom of the support 71.

[0024] In this embodiment: the hand-held bracket 73 facilitates the movement of the entire device; the support 71 and the height adjustment block 72 are provided, and since the support 71 has a screw hole at the bottom and the height adjustment block 72 has a screw rod at the position corresponding to the screw hole, the height adjustment block 72 can be adjusted by rotating the screw hole and the screw rod.

[0025] Specifically, such as Figure 2 As shown, a semi-circular fence frame 22 is fitted on the rear side of the oil pipe 2, and the bottom of the fence frame 22 is connected to the base 7.

[0026] In this embodiment, the fence frame 22 serves to fix and limit the oil pipe 2.

When the oil pipe 2 is inserted into the oil pipe 2 holder, it is pressed down forcefully, so that the vertical pipe pierces the aluminum foil of the can opening 203, thereby achieving the supply of grease. When replacing the oil pipe 2, the valve 81 can be closed to prevent air from entering the connecting pipe 8.

[0030] Working principle: When in use, the power bank 3 is fully charged, and the required amount of oil pipe 2 is lifted by the hand-held bracket 73 and moved to the required position. If the position of the device is not level, the bottom plate can be leveled and placed stably by adjusting the height adjustment block 72 at the bottom. The power is turned on by the controller 6 to connect the power to the entire device. The flow rate is set on the flow meter 5. The power is turned on to start the device, and the oil gun 4 is pressed to perform bearing oil injection.
