Description

Technical Field

[0001] The utility model belongs to the technical field of grease lubrication, and in particular relates to a lubricating grease filling and recovery device for a transfer machine. Background Art

[0002] Most high-speed rotating machinery uses thin grease for bearing lubrication, and the operation cycle of the machinery depends on regular greasing. The conventional greasing method is for equipment maintenance personnel to hold a metal oil pot, extract a small amount of grease from the oil barrel, and then add it to the corresponding rotating machine bearing chamber one by one. This conventional small oil pot oiling method not only wastes manpower, but is also restricted by the space of the on-site equipment, which brings certain difficulties to the grease filling work.

[0003] At present, the patent with application number 201720803018.4 discloses a lubricating grease filling equipment, including a box body, a lubricating grease filling pump, a hose, a lubricating grease filling gun, a placement device, etc.; a lubricating grease filling pump is provided on the right side of the bottom of the box body, a hose is provided on the lubricating grease filling pump, a lubricating grease filling gun is connected to the right end of the hose, a placement device is provided on the upper right side of the box body, a feed pipe is provided on the right side of the top of the box body, and an indicating device is provided on the upper part of the box body.

[0004] Although this device solves the problems of manpower waste and space constraints caused by the traditional direct oiling method, when different brands of lubricants need to be used for multiple transfer machines, this equipment needs to go back and forth to get oil and fill it, resulting in a certain amount of time waste; at the same time, the transfer machine needs to replace the grease after long-term operation, and when replacing it, the aged grease can only be poured out from the oil drain hole at the bottom of the bearing chamber. This device cannot be recycled, so it causes grease waste and environmental pollution problems. Utility Model Content

[0005] The utility model aims to provide a lubricating grease filling and recovery device for a transfer machine, which can contain two different lubricating greases at one time and can recover the aged grease in a bearing chamber to an oil tank.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A lubricating grease filling and recovery device for a transfer machine comprises: an oil tank and an oil pump assembly arranged on the top of the oil tank, the interior of the oil tank is divided into a first cavity, a second cavity and a third cavity by two partitions perpendicular to the bottom of the oil tank; a first oil suction pipe and a second oil suction pipe are respectively arranged inside the first cavity and the second cavity, the first oil suction pipe and the second oil suction pipe extend to the third cavity respectively, and the extension ends are respectively connected to two bottom inlets of a three-way ball valve arranged inside the third cavity; the oil pump assembly comprises an oil pump body, a regulating switch and an external oil pipe; the top outlet of the three-way ball valve is upwardly connected to the oil pump body through the internal oil pipe;

[0008] When filling oil, by adjusting the switching handle set on the outside of the oil tank to control the three-way ball valve and the adjusting switch set on the shell of the oil pump assembly in sequence, the sucked oil is transported to the oil filling pipe connected to the external oil pipe through the internal oil pipe and the external oil pipe set at the oil outlet of the oil pump body in sequence, thereby completing the oil filling.

[0009] Furthermore, the oil filling pipe is a telescopic oil pipe, and the oil filling pipe is fixed on the side of the oil tank.

[0010] Furthermore, the oil tank is provided with liquid meters on the sides of the first cavity and the second cavity, respectively, for observing the oil volume inside the cavity.

[0011] Furthermore, the oil tank is provided with ventilation holes at the top of the first cavity and the second cavity respectively, and a handle is also provided at the top.

[0012] Furthermore, the oil pump assembly also includes a battery compartment for power supply.

[0013] Furthermore, the bottom of the fuel tank is provided with universal wheels of no less than .

[0014] Furthermore, an upper partition is arranged between the top of the oil tank and the partition.

[0015] Furthermore, the fuel tank is made of steel or aluminum alloy.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model solves the problems existing in the existing device by making improvements on the basis of the existing oil tank and oil pump assembly. Specifically, the interior of the oil tank is divided into three parts, namely, a first cavity, a second cavity and a third cavity, by two partitions, and then two first oil suction pipes and a second oil suction pipe are respectively arranged inside the first cavity and the second cavity, and the two oil suction pipes are respectively extended to the third cavity, and the extended ends are respectively connected to the two bottom inlets of a three-way ball valve arranged inside the third cavity, and finally, the outlet of the three-way ball valve is connected to the oil pump through the internal oil pipe, and the oil pump assembly is finally connected to the filling pipe through the external oil pipe. By dividing the oil tank into three cavities, two different lubricating oils can be contained in different cavities, which meets the needs of using different brands of lubricating grease in the transfer machine. In addition, when the transfer machine needs to recycle aged grease, it is only necessary to adjust the switching handle set on the outside of the oil tank to control the three-way ball valve and the adjusting switch set on the shell of the oil pump assembly in sequence, so that the filling oil pipe can reversely recycle the aged grease, and finally recycle the aged grease into the cavity, thereby solving the problems of grease waste and environmental pollution caused by the traditional device because it cannot recycle.
