[0023] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0024] In the present disclosure, unless otherwise specified, the directional words such as "up", "down", "left", "right", etc. used to indicate the direction or position relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific directional structure and operation.

[0025] In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0026] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0027] refer to Figures 1 to 2 As shown, the first aspect of the present disclosure provides a heavy vehicle shunting machine hydraulic oil system assembly, including a hydraulic oil tank 10 and a cooling assembly 20. The hydraulic oil tank 10 has an oil chamber 11 for storing hydraulic oil. The cooling assembly 20 includes a first connecting pipe 21, a second connecting pipe 22, a third connecting pipe 23, an oil cooler 24 and an oil pump 25. The first connecting pipe 21 is used to connect the oil chamber 11 with the oil cooler 24, the second connecting pipe 22 is used to connect the oil cooler 24 and the oil pump 25, and the third connecting pipe 23 is used to connect the oil pump 25 and the oil chamber 11.

[0028] Through the above technical solution, during the operation of the heavy vehicle shunting locomotive, the oil pump 25 and the oil cooler 24 can be turned on. At this time, under the pumping action of the oil pump 25, the oil in the oil chamber 11 can be sucked into the oil cooler 24 through the first connecting pipe 21. After being cooled and cooled by the oil cooler 24 to become low-temperature oil, it is returned to the oil chamber 11 through the second connecting pipe 22 and the third connecting pipe 23 in turn, thereby realizing the circulation cooling of the oil, reducing the temperature of the oil, and thus reducing the impact of the high oil temperature on the performance and service life of the hydraulic oil system of the heavy vehicle shunting locomotive.

[0029] In an exemplary embodiment provided herein, the oil cooler 24 may optionally include a coolant line for circulating coolant and an oil line for circulating oil, with the coolant line and the oil line being positioned flush against each other. This allows the coolant, while circulating within the coolant line, to exchange heat with the high-temperature oil circulating within the oil line, thereby removing heat from the oil and cooling the oil.

[0030] Specifically, in the embodiment provided in the present disclosure, the above-mentioned oil cooler 24 can be a water-cooled oil cooler 24, or, in other embodiments provided in the present disclosure, the above-mentioned oil cooler 24 can also be an air-cooled oil cooler 24. In short, as long as the oil can be cooled, the present disclosure does not limit the specific heat exchange type and heat exchange method of the above-mentioned oil cooler 24.

[0031] Optionally, the oil cooler 24 may be provided with an oil drain port that communicates with the oil pipeline and is located at the lowest point of the oil pipeline. Thus, during the oil cooling process, if the oil cooler 24 malfunctions or the oil needs to be replaced, the oil drain port can be opened to allow the oil to flow out, thereby facilitating inspection and maintenance of the oil cooler 24 and the hydraulic oil tank 10.

[0032] Furthermore, the oil drain port is arranged at the lowest point of the oil pipeline, which makes it easier for the oil to flow out of the oil pipeline under the action of its own gravity.

[0033] Too high or too low a temperature of the oil in the hydraulic oil tank 10 will affect the performance of the heavy vehicle shunting machine hydraulic oil system. In order to achieve accurate heat exchange of the oil in the hydraulic oil tank 10, in the embodiment provided in the present disclosure, Figure 1 As shown, the heavy vehicle shunting machine hydraulic oil system assembly also includes a temperature sensor 30. The detection end of the temperature sensor 30 is disposed in the oil chamber 11 and is used to detect the temperature of the oil in the oil chamber 11. In this way, during the process of circulating and cooling the oil using the cooling assembly 20, the temperature sensor 30 can achieve real-time monitoring of the oil temperature in the oil chamber 11, thereby controlling the temperature in the oil chamber 11 within an optimal range.

[0034] Specifically, when the temperature sensor 30 detects that the temperature of the oil in the oil chamber 11 is too high, the operator can increase the pumping speed of the oil pump 25 to improve the cooling efficiency of the oil, thereby cooling the oil to a lower temperature; when the temperature sensor 30 detects that the temperature of the oil in the oil chamber 11 is too low, the operator can reduce the heat exchange between the oil and the oil by reducing the pumping speed of the oil pump 25, thereby avoiding the oil temperature being too low.

[0035] Alternatively, as Figure 1 As shown, the cooling assembly 20 further includes a regulating valve 26, which is connected to the second connecting pipe 22 and is used to control the on / off state of the second connecting pipe 22. By controlling the regulating valve 26, the flow of oil in the second connecting pipe 22 can be controlled, thereby preventing the residual oil in the first connecting pipe 21 and the second connecting pipe 22 from continuing to flow after the oil pump 25 is turned off.

[0036] Further, if Figure 1 As shown, the cooling assembly 20 may further include a flow meter 27, which is disposed on the first connecting pipe 21 or the second connecting pipe 22 and is used to measure the flow rate of the oil flowing out of the oil chamber 11 from the first connecting pipe 21 or the flow rate of the oil flowing into the oil chamber 11 from the second connecting pipe 22. The flow meter 27 can monitor the flow rate of the heat exchange oil to achieve precise control of the flow rate of the oil during the heat exchange process, thereby ensuring that the oil flowing back into the oil chamber 11 can be maintained within a constant temperature range.

[0037] The present disclosure does not limit the specific type of the flow meter 27. For example, in the embodiment provided in the present disclosure, the flow meter 27 can be one of a volumetric flow meter, an electromagnetic flow meter, and an ultrasonic flow meter.

[0038] Alternatively, as Figure 1 As shown, the heavy vehicle shunting machine hydraulic oil system assembly may further include a filter 40, which is connected to the third connecting pipe 23. On the one hand, the filter 40 provided on the third connecting pipe 23 can filter impurities in the oil, thereby preventing impurities in the oil pump 25 and the oil cooler 24 from entering the oil chamber 11 and causing contamination of the oil chamber 11. On the other hand, it can also filter and purify the oil flowing out of the oil chamber 11, thereby improving the cleanliness of the oil and reducing the damage to the heavy vehicle shunting machine hydraulic oil system caused by impurities in the oil.

[0039] It should be noted that the above-mentioned filter 40 should be connected to the third connecting pipe 23 in a detachable manner, so that the operator can remove the filter 40 from the third connecting pipe 23 at regular intervals and clean the impurities collected in the filter 40 to avoid clogging the third connecting pipe 23.

[0040] Optionally, the first connecting pipe 21 communicates with the oil chamber 11 through a heater hole pre-set on the hydraulic oil tank 10, and the third connecting pipe 23 communicates with the oil chamber 11 through another heater hole pre-set on the hydraulic oil tank 10. In other words, the connection between the first connecting pipe 21 and the third connecting pipe 23 and the hydraulic oil tank 10 does not require the provision of connection holes in the hydraulic oil tank 10, thereby avoiding structural changes to the hydraulic oil tank 10, reducing modification costs, and not affecting the overall strength of the hydraulic oil tank 10.

[0041] Optionally, the first connecting tube 21, the second connecting tube 22, and the third connecting tube 23 are all metal hoses. On the one hand, metal hoses have good thermal conductivity. Thus, when the oil flows through the first connecting tube 21, the second connecting tube 22, and the third connecting tube 23, the oil can transfer part of its own heat to the first connecting tube 21, the second connecting tube 22, and the third connecting tube 23, and then transfer it to the atmosphere through the first connecting tube 21, the second connecting tube 22, and the third connecting tube 23. On the other hand, metal hoses also have good high-temperature resistance and are not easily deformed or aged under the action of high-temperature oil. They are strong, durable, and have a longer service life.

[0042] like Figure 2 As shown, the heavy vehicle shunting machine hydraulic oil system assembly provided by the present disclosure may further include a controller 100. In the embodiment where the heavy vehicle shunting machine hydraulic oil system assembly further includes a temperature sensor 30, as shown in FIG. Figure 2 As shown, the controller 100 can be respectively connected to the temperature sensor 30, the oil pump 25 and the oil cooler 24 by signal. In this way, when the temperature sensor 30 detects that the temperature exceeds the preset temperature, the temperature signal can be transmitted to the controller 100, and the controller 100 controls the operation of the oil pump 25 and the oil cooler 24 to achieve automatic cooling of the oil; similarly, when the temperature sensor 30 detects that the temperature is lower than the preset temperature, the temperature signal can be transmitted to the controller 100, and the controller 100 can control the oil pump 25 and the oil cooler 24 to stop operating or reduce the operating efficiency, thereby increasing the temperature of the oil.

[0043] The present disclosure does not limit the signal connection methods between the controller 100 and the temperature sensor 30, the oil pump 25 and the oil cooler 24 respectively. For example, the controller 100 can be connected to the temperature sensor 30, the oil pump 25 and the oil cooler 24 respectively via Bluetooth, or the controller 100 can be connected to the temperature sensor 30, the oil pump 25 and the oil cooler 24 respectively via a wireless network.

[0044] The second aspect of the present disclosure provides a heavy vehicle shunting machine, comprising the above-mentioned heavy vehicle shunting machine hydraulic oil system assembly. The heavy vehicle shunting machine has all the beneficial effects of the above-mentioned heavy vehicle shunting machine hydraulic oil system assembly, which are not described in this disclosure.

[0045] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0047] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
