Description

Technical Field

[0001] This utility model relates to the field of downhole operation equipment technology, and in particular to a pneumatic refueling device. Background Technology

[0002] Roadheaders consume a large amount of lubricating grease during underground operations, and large oil drums are usually used as containers for storage. However, due to the large weight of the fully loaded oil drums, traditional oil extraction methods have significant operational limitations.

[0003] In the current grease replenishment process at the work site, operators need to work in pairs to pour the oil drum and transfer the lubricating grease to a special refueling device. This operation mode not only poses certain safety hazards, but also easily leads to grease spillage, polluting the surrounding environment and wasting grease.

[0004] Therefore, to address the above issues, a pneumatic refueling device can be designed, connected to the downhole compressed air pipeline, and used to drive the automated extraction and transfer of lubricating grease using wind power. In actual operation, a single operator can complete the grease replenishment operation, which reduces labor intensity, fundamentally eliminates the safety hazards of manual handling, effectively controls the risk of grease leakage, and prevents grease waste. Utility Model Content

[0005] To address the current grease replenishment process at work sites, where operators must work in pairs to empty oil drums and transfer lubricating grease to specialized refueling equipment, this work mode not only poses certain safety hazards but also easily leads to grease spillage, polluting the surrounding environment and wasting grease.

[0006] The technical solution of this utility model is as follows: a pneumatic refueling device, including an oil drum, a large drum cover, a small drum cover, a connecting pipe, an oil suction pipe, and an oil delivery hose. The large drum cover is located at the upper end of the oil drum, and the small drum cover is threadedly connected to the upper end of the large drum cover. The connecting pipe is connected through the upper end of the small drum cover, and an air duct interface is provided at the other end of the connecting pipe. A shut-off valve is integrated inside the connecting pipe, and a pressure relief valve is connected through the periphery of the connecting pipe. The oil suction pipe vertically penetrates the large drum cover and extends into the inner cavity of the oil drum. The oil delivery hose is connected through the ends of the oil suction pipe.

[0007] Preferably, an air duct interface is set to connect the connecting pipe to the downhole compressed air pipeline, so that air can be supplied to the oil drum through the connecting pipe. The air pressure forces the grease in the oil drum into the oil extraction pipe, and then delivers it to the dedicated refueling device through the oil delivery hose. The air supply volume can be adjusted by setting a shut-off valve, thereby controlling the oil delivery speed of the oil delivery hose and making it easy to control the refueling volume.

[0008] Preferably, a mounting bracket is fixedly installed inside the connecting pipe, and a fan wheel is rotatably connected inside the mounting bracket.

[0009] Preferably, a snap-fit ​​sleeve is fixedly installed at the lower end of the impeller, and a stirring shaft is provided inside the snap-fit ​​sleeve. An elastic retaining strip is fixedly installed at the upper end of the stirring shaft.

[0010] Preferably, a spiral stirring blade is fixedly installed on the periphery of the stirring shaft, and the spiral stirring blade is located below the snap-fit ​​sleeve.

[0011] As a preferred option, the oil extraction pipe and the oil delivery hose are connected by a flange to achieve a through connection.

[0012] As a preferred option, a corrugated compensating pipe is welded to the lower end of the sucker pipe, and multiple sets of through-holes are opened on the wall of the corrugated compensating pipe.

[0013] Preferably, the oil extraction pipe is fitted with a sealing sleeve, which fits tightly against the barrel lid.

[0014] The beneficial effects of this utility model are:

[0015] By drilling holes in the large drum lid and threading a small drum lid onto the upper part of the large drum lid, the stirring shaft is quickly snapped and fixed below the impeller using a snap-fit ​​sleeve and elastic clip. The large drum lid is then placed back on the oil drum and tightened. The oil extraction pipe is inserted into the inner cavity of the oil drum through the hole in the surface of the large drum lid. The oil delivery hose is then connected to the oil extraction pipe via a flange connection, and the outlet of the oil delivery hose is aligned with the dedicated refueling device. The shut-off valve is then closed, and the connecting pipe is connected to the downhole compressed air pipeline through the air duct interface. When refueling, the shut-off valve is opened, and air is supplied to the oil drum through the connecting pipe. The air pressure forces the grease in the oil drum into the oil extraction pipe and then delivers it to the dedicated refueling device through the oil delivery hose. This allows a single operator to complete the grease replenishment operation, reducing labor intensity, fundamentally eliminating the safety hazards of manual handling, effectively controlling the risk of grease leakage, and preventing grease waste.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 and Figure 2 This utility model provides an embodiment of a pneumatic refueling device, including an oil drum 1, a large drum cover 2, a small drum cover 3, a connecting pipe 4, an oil extraction pipe 5, and an oil delivery hose 6. The large drum cover 2 is located at the upper end of the oil drum 1, and the small drum cover 3 is threadedly connected to the upper end of the large drum cover 2. The connecting pipe 4 is connected through the upper end of the small drum cover 3, and the other end of the connecting pipe 4 is provided with a duct interface 402. A shut-off valve 401 is integrated inside the connecting pipe 4, and a pressure relief valve 7 is connected through the periphery of the connecting pipe 4. The oil extraction pipe 5 vertically penetrates the large drum cover 2 and extends to the oil drum. 1. The inner cavity is connected to the oil delivery hose 6 and the oil extraction pipe 5. The air pipe interface 402 is set to connect the connecting pipe 4 to the downhole compressed air pipeline, so that air can be supplied to the oil drum 1 through the connecting pipe 4. The air pressure forces the grease in the oil drum 1 into the oil extraction pipe 5, and then delivers it into the special refueling device through the oil delivery hose 6. The air supply volume can be adjusted by setting the shut-off valve 401, and the pressure relief valve 7 can be set to release the pressure in the oil drum, thereby controlling the oil output speed of the oil delivery hose 6 and making it easy to control the refueling volume.

[0025] Please see Figure 2 , Figure 4 and Figure 5In this embodiment, a mounting bracket 403 is fixedly installed inside the connecting pipe 4. A fan wheel 404 is rotatably connected inside the mounting bracket 403. A snap-fit ​​sleeve 405 is fixedly installed at the lower end of the fan wheel 404. A stirring shaft 406 is provided inside the snap-fit ​​sleeve 405. An elastic retaining strip 407 is fixedly installed at the upper end of the stirring shaft 406. A spiral stirring blade 408 is fixedly installed around the stirring shaft 406 and is located below the snap-fit ​​sleeve 405. The mounting bracket 403 is used to support and position the fan wheel 404. The snap-fit ​​sleeve 405 and the elastic retaining strip 407 cooperate to achieve quick connection and fixation between the stirring shaft 406 and the fan wheel 404. When air is supplied to the connecting pipe 4, the air pressure drives the fan wheel 404 to rotate, which in turn drives the stirring shaft 406 to rotate synchronously. Thus, the spiral stirring blade 408 dynamically stirs the oil stored in the oil tank 1, ensuring the quality stability of the output oil.

[0026] Please see Figure 2 , Figure 3 and Figure 6 In this embodiment, the oil extraction pipe 5 and the oil delivery hose 6 are connected by a flange. The flange connection structure facilitates quick disassembly, assembly, and maintenance of the oil extraction pipe 5 and the oil delivery hose 6. A corrugated compensating pipe 501 is welded to the lower end of the oil extraction pipe 5. Multiple sets of through oil inlet holes 502 are opened on the wall of the corrugated compensating pipe 501. A sealing sleeve 503 is fitted around the oil extraction pipe 5. The sealing sleeve 503 fits tightly with the large barrel cover 2. By setting the corrugated compensating pipe 501, it can adapt to the inner cavity of the oil barrel 1 of different heights. By setting the oil inlet holes 502, it can avoid the corrugated compensating pipe 501 from contacting the bottom of the oil barrel 1, ensuring that the grease can effectively enter the extraction pipe. By setting the sealing sleeve 503, it can ensure the sealing between the oil extraction pipe 5 and the large barrel cover 2.

[0027] When working, first drill holes in the large barrel lid 2, and thread the small barrel lid 3 to the upper end of the large barrel lid 2. Use the snap-fit ​​sleeve 405 and the elastic clip 407 to quickly snap and fix the stirring shaft 406 under the impeller 404. Then put the large barrel lid 2 back on the oil barrel 1 and tighten it.

[0028] Insert the oil suction pipe 5 into the inner cavity of the oil drum 1 through the hole on the surface of the large drum cover 2. The corrugated compensation pipe 501 welded below the oil suction pipe 5 can adapt to the inner cavity of the oil drum 1 of different heights. The oil inlet hole 502 can prevent the corrugated compensation pipe 501 from contacting the bottom of the oil drum 1, ensuring that the grease can effectively enter the oil suction pipe 5. The sealing sleeve 503 can ensure the sealing between the oil suction pipe 5 and the large drum cover 2. Then, connect the oil delivery hose 6 to the oil suction pipe 5 through the flange connection, and align the outlet of the oil delivery hose 6 with the special refueling device.

[0029] Close the shut-off valve 401 and connect the connecting pipe 4 to the downhole compressed air pipeline using the air pipe interface 402. When refueling, open the shut-off valve 401 and supply air to the oil drum 1 through the connecting pipe 4. The air pressure forces the grease in the oil drum 1 into the oil extraction pipe 5 and delivers it into the special refueling equipment through the oil delivery hose 6. The shut-off valve 401 can be used to adjust the air supply volume, thereby controlling the oil output speed of the oil delivery hose 6, which facilitates the control of the refueling volume. A single operator can complete the grease replenishment operation. When air is supplied to the connecting pipe 4, the air pressure drives the impeller 404 to rotate, which in turn drives the stirring shaft 406 to rotate synchronously. The spiral stirring blades 408 dynamically stir the grease stored in the oil drum 1, ensuring the quality stability of the output grease. After the oil extraction operation is completed, the pressure in the oil drum 1 can be released in time using the pressure relief valve 7.

[0030] After the grease in oil drum 1 is completely extracted, repeat the above steps to easily transfer the equipment to another oil drum 1. The operation is convenient and quick.

[0031] Through the above steps, the connecting pipe 4 is connected to the downhole compressed air pipeline via the air duct interface 402. Air can then be supplied to the oil drum 1 through the connecting pipe 4. The air pressure forces the grease in the oil drum 1 into the oil extraction pipe 5, and then delivers it to the dedicated refueling device through the oil delivery hose 6. The air supply volume can be adjusted by setting the shut-off valve 401, thereby controlling the oil delivery speed of the oil delivery hose 6 and facilitating the control of the refueling volume. In actual operation, a single operator can complete the grease replenishment operation. This solves the problem that in the current grease replenishment process at the work site, operators need to work in pairs to tilt the oil drum 1 and transfer the lubricating grease to the dedicated refueling device. This operation mode not only has certain safety hazards, but also easily leads to grease spillage, polluting the surrounding environment and wasting grease.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
