Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an embedded air compressor for engineering machines. Background Technology

[0002] In the field of engineering construction, engineering vehicles are important construction equipment, and their operating efficiency is closely related to the performance of their supporting equipment. Among them, air compressors, as key equipment for providing compressed air, are widely used in core components of engineering vehicles such as pneumatic systems and braking systems. Currently, the air compressors used in engineering vehicles mostly adopt a flat bottom design in terms of structural design to adapt to traditional flat load-bearing plates.

[0003] However, with the diversification of functions and the increasing complexity of structures in engineering vehicles, many engineering vehicles have raised structures on their carrier plates to meet specific installation requirements or integrate certain functional components. These raised structures may be connectors for fixing other equipment, reinforcing ribs for strengthening the carrier plate, or functional protrusions that cooperate with other systems in the vehicle. When using existing air compressors with flat bottom surfaces, gaps form between the air compressor and the carrier plate because the bottom surface of the air compressor cannot be adapted to the raised structures on the carrier plate. This not only affects the stability of the air compressor installation, but more importantly, this mismatch prevents the air compressor's casing structure from fully utilizing the effective space of the carrier plate. Areas inside the casing that could accommodate related pipes, wiring, or auxiliary components are wasted due to interference with the carrier plate protrusions, limiting the space utilization of the casing and consequently affecting the compactness of the overall equipment layout of the engineering vehicle.

[0004] Meanwhile, during the actual operation of engineering vehicles, the air compressor generates a large amount of heat. If it cannot be dissipated in time, the equipment temperature will become too high, affecting its performance and service life. Therefore, the ventilation design of the casing is crucial for the stable operation of the air compressor. However, in addition to the air compressor, the chassis of engineering vehicles usually needs to be equipped with other components such as hydraulic pumps, generators, and control boxes. The arrangement of these devices occupies the limited space of the chassis, compressing the airflow channels around the casing.

[0005] Existing air compressor ventilation designs often employ fixed vents or simple heat dissipation structures. When equipment is densely packed on the carrier plate, it's difficult to flexibly adjust ventilation paths based on the layout of surrounding equipment, easily leading to ventilation dead zones and heat accumulation inside the casing. Furthermore, heat generated by other equipment during operation may interfere with the air compressor's heat dissipation, further reducing ventilation efficiency. Optimizing the ventilation design of the air compressor casing and improving heat dissipation while ensuring a reasonable layout of multiple devices on the carrier plate has become a pressing problem to be solved in the design of air compressors for engineering vehicles. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an embedded air compressor for engineering machines.

[0007] An embedded air compressor for engineering machines designed for this purpose includes a chassis, the lower surface of which is provided with an upwardly recessed and through-hole embedded slot, and the wall of the embedded slot is provided with a first ventilation opening that communicates with the interior of the chassis.

[0008] The chassis contains a main unit, a gas-liquid separator, and a cooler.

[0009] The cooler is installed on either side of the recessed slotted chassis;

[0010] The main unit is connected to an air inlet pipe and an air outlet pipe, and the air outlet pipe is connected to the input end of the gas-liquid separator;

[0011] The gas-liquid separator is provided with a gas output end and an oil output end;

[0012] The cooler is provided with a gas cooling channel and an oil cooling channel;

[0013] The gas output end is connected to the gas cooling channel input end by a gas delivery pipe;

[0014] The oil output end is connected to the input end of the oil cooling channel by a first oil delivery pipe;

[0015] The output end of the oil cooling channel is connected to the oil inlet of the main unit via a second oil delivery pipe.

[0016] Preferably, an oil filter is provided at the output end of the oil cooling channel, and the second oil delivery pipe is connected to the output end of the oil filter.

[0017] Preferably, a pressure sensor is provided between the input end of the second oil delivery pipe and the output end of the oil filter.

[0018] Preferably, the left and right sides of the embedded slot are provided with first ventilation openings.

[0019] Preferably, the chassis has a heat dissipation vent on the wall near the cooler.

[0020] Preferably, the chassis is provided with a second ventilation opening.

[0021] Compared with the prior art, this embedded air compressor for engineering machines has many significant advantages:

[0022] From a space adaptation and utilization perspective, the recessed, through-type embedded slot on the lower surface of the chassis precisely fits the raised structure on the engineering vehicle's carrier plate, allowing the air compressor to be stably embedded in the raised area of ​​the carrier plate. This effectively solves the problem of incompatibility between traditional flat-bottomed air compressors and carrier plates with raised sections. This embedded design not only enhances installation stability but also makes full use of the space occupied by the raised sections of the carrier plate, avoiding wasted space between the chassis and the carrier plate. This significantly improves the overall space utilization of the chassis, allowing for a more compact and rational use of space on the carrier plate.

[0023] In terms of ventilation and heat dissipation, the recessed slotted wall features a first ventilation port that connects to the interior of the chassis. Combined with the front-to-back slotted structure, this creates a highly efficient airflow channel. When the air compressor is embedded in the raised carrier plate, the slotted area guides external airflow smoothly through the first ventilation port into the chassis. Simultaneously, the cooler is positioned on either side of the recessed slot within the chassis, fully utilizing the airflow advantage provided by the slots to enhance cooling efficiency. Furthermore, this design reduces mutual interference with ventilation from other surrounding equipment, lowers the probability of ventilation dead zones, effectively improves heat dissipation within the chassis, and ensures the stability of the equipment during long-term operation.

[0037] See Figures 1-5 An embedded air compressor for engineering machines includes a housing 10. The lower surface of the housing 10 has an upwardly recessed, through-hole embedded slot 100. The slot wall of the embedded slot 100 has a first ventilation opening 110 communicating with the interior of the housing 10. The housing 10 houses a main unit 20, a gas-liquid separator 30, and a cooler 40. The cooler 40 is located on either side of the embedded slot 10. The main unit 20 is connected to an inlet pipe 210 and an outlet pipe 220. The gas outlet pipe 220 is connected to the input end of the gas-liquid separator 30; the gas-liquid separator 30 is provided with a gas output end and an oil output end; the cooler 40 is provided with a gas cooling channel and an oil cooling channel; the gas output end is connected to the input end of the gas cooling channel via a gas delivery pipe 50; the oil output end is connected to the input end of the oil cooling channel via a first oil delivery pipe 610; the output end of the oil cooling channel is connected to the oil input port of the main unit 20 via a second oil delivery pipe 620.

[0038] The working principle of this embedded air compressor used in engineering equipment is as follows:

[0039] During operation, outside air enters the main unit 20 through the intake pipe 210 connected to the main unit 20, and the main unit 20 compresses the incoming air. The compressed air is then transported to the input end of the gas-liquid separator 30 through the outlet pipe 220. The gas-liquid separator 30 separates the compressed air, separating the gas and oil.

[0040] The separated gas flows out from the gas output end of the gas-liquid separator 30 and enters the gas cooling channel of the cooler 40 through the gas delivery pipe 50. After being cooled in the gas cooling channel, it can be delivered to the corresponding pneumatic system of the engineering vehicle. The separated oil flows out from the oil output end of the gas-liquid separator 30 and enters the oil cooling channel of the cooler 40 through the first oil delivery pipe 610. After being cooled, it flows back to the oil inlet of the main unit 20 through the second oil delivery pipe 620 to provide lubrication for the operation of the main unit 20.

[0041] Meanwhile, since the embedded slot 100 on the lower surface of the chassis 10 is through, and the slot wall is provided with a first ventilation port 110 that communicates with the inside of the chassis 10, external airflow can flow along the embedded slot 100 and enter the inside of the chassis 10 through the first ventilation port 110, providing good ventilation and heat dissipation conditions for the host 20, gas-liquid separator 30 and especially the cooler 40 inside the chassis 10, ensuring the stable operation of each component.

[0042] See Figure 4 An oil filter 80 is installed at the output end of the oil cooling channel, and the second oil delivery pipe 620 is connected to the output end of the oil filter 80. In the working system of this embedded air compressor, the oil filter 80 at the output end of the oil cooling channel plays a crucial role. When the oil cooled by the oil cooling channel of the cooler 40 flows out from the output end, it first enters the oil filter 80. During the lubrication and other operations of the main unit 20, the oil may accumulate metal shavings due to equipment wear, rubber particles formed by aging seals, or dust and other impurities mixed in with the air. The oil filter 80 can effectively filter these oils containing impurities, intercepting solid impurities and contaminants, preventing them from flowing back to the oil inlet of the main unit 20 through the second oil delivery pipe 620.

[0043] See Figure 4 A pressure sensor 70 is installed between the input end of the second oil delivery pipe 620 and the output end of the oil filter 80. The pressure sensor 70 performs crucial pressure monitoring and system status feedback functions. After being filtered by the oil filter 80, the oil needs to be delivered to the oil inlet of the main unit 20 through the second oil delivery pipe 620, and the pressure sensor 70 can detect the oil pressure in this delivery process in real time. When the oil filter 80 accumulates more impurities due to prolonged use, the flow resistance of the filter increases, causing abnormal pressure changes between the output end of the oil filter 80 and the input end of the second oil delivery pipe 620. The pressure sensor 70 can promptly detect these pressure changes: if the pressure value is below the normal range, it may indicate that the oil filter 80 is damaged or the connecting pipe is leaking, resulting in insufficient oil delivery pressure; if the pressure value is significantly higher than the normal range, it indicates that the oil filter 80 may be severely clogged, obstructing oil flow. This prevents damage to the main unit 20 due to insufficient oil supply.

[0044] See Figure 1The embedded slot 100 has first ventilation openings 110 on both the left and right sides of its slot walls. From an airflow perspective, the first ventilation openings 110 on both sides, together with the front-to-back embedded slot 100, form a more complete airflow channel network. When external airflow enters the slot, it can flexibly enter the chassis through the first ventilation opening 110 on either the left or right side, breaking the limitation of airflow path imposed by a single-direction ventilation opening. This dual-sided arrangement can adapt to the complex equipment layout around the engineering vehicle's platform. Regardless of whether other equipment forms a blockage on the left or right side of the slot, the first ventilation opening 110 on the other side can still ensure effective airflow entry, reducing ventilation interruption problems caused by interference from surrounding equipment. In terms of heat dissipation balance, since the cooler is located in the chassis on either the left or right side of the embedded slot 100, the dual first ventilation openings 110 can specifically supplement the area where the cooler is located with cool air. The first vent on the left side 110 can directly deliver airflow to the cooler located on the left side, while the first vent on the right side 110 can provide cooling airflow to the host, air-liquid separator and other heat-generating components, so that the heat in each area inside the chassis can be carried away in time, avoiding local heat accumulation and improving the uniformity of overall heat dissipation.

[0045] See Figure 1 The chassis 10 has a heat dissipation vent 130 on the wall near the cooler 40.

[0046] See Figure 1 The chassis 10 is provided with a second ventilation opening 120.

[0047] In this invention, the cooler 40 is either a water-cooled cooler or an air-cooled cooler.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.

Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
