[0035] The following will describe the speed reducer liquid level detection device and working machine of the embodiments of the present application in combination with Figures 1 to 5

[0036] ​According to an embodiment of this utility model, in one aspect, a speed reducer liquid level detection device is provided, including a frame 1, a speed reducer 2, an oil filling / draining pipe 3, a first hose 4, a second hose 5, and an oil level detection device 6.

The reducer 2 is provided with an oil filler port 201 and an oil drain port 202, which are spaced apart along the height direction of the frame 1. An oil filling / draining pipe 3 is provided on one side of the frame 1 and extends along the height direction of the frame 1.

[0037] One end of the first hose 4 is connected to the filler port 201, and the other end is connected to the first end 301 of the filler / discharge hose 3. Specifically, the first end 301 of the filler / discharge hose 3 and the filler port 201 are respectively equipped with pipe fittings 11 for quick connection with the first hose 4.

[0038] One end of the second hose 5 is connected to the drain port 202, and the other end is connected to the second end 302 of the oil supply / drain pipe 3. Specifically, the second end 302 of the oil supply / drain pipe 3 and the drain port 202 are respectively equipped with pipe fittings 11 for quick connection with the second hose 5. The type and specifications of the pipe fittings 11 can be selected according to actual usage requirements.

[0039] An oil level detection device 6 is installed on the oil filling / draining pipe 3 to monitor the oil level within the pipe. With this configuration, gear oil from the reducer 2 is introduced into the oil filling / draining pipe 3 via the first hose 4 and the second hose 5. According to the principle of communicating vessels, the fluid level in the oil filling / draining pipe 3 is consistent with the fluid level inside the reducer 2. Therefore, the oil level inside the reducer 2 can be quickly determined by the fluid level measured by the oil level detection device 6. Furthermore, the adjustability of the hoses avoids pipeline interference, facilitates the overall vehicle piping layout, and the device has high versatility. It should be noted that, as shown in the example... Figure 1 Regarding the placement of the reducer level detection device shown, the vertical direction in the figure corresponds to the height of frame 1.

[0040] In some embodiments of this utility model, the oil level detection device 6 is a liquid level gauge, such as... Figure 1 As shown, the first end 301 of the oil supply pipe 3 has a first opening, and a level gauge is inserted into the first opening, with the level gauge and the first opening being sealed together. This configuration allows the level gauge to measure the oil level, thereby determining the oil condition inside the reducer 2 and enabling timely replenishment of gear oil to prevent wear on the gears of the reducer 2. Furthermore, the first opening facilitates the addition of oil, making maintenance of the reducer 2 easier. Additionally, the level gauge can be used to seal the first opening, preventing external impurities from entering the internal oil passages.

[0041] In some embodiments of this utility model, such as Figure 2As shown, one of the liquid level gauge and the oil filling pipe 3 is provided with a first internal thread, and the other is provided with a first external thread matched with the first internal thread. That is, the liquid level gauge is provided with the first internal thread, and the first end 301 of the oil filling pipe 3 is correspondingly provided with the matched first external thread; or the first end 301 of the oil filling pipe 3 is provided with the first internal thread, and the liquid level gauge is correspondingly provided with the matched first external thread. In this way, the liquid level gauge and the oil filling pipe 3 are screwed together, so that the liquid level gauge can be screwed out of the oil filling pipe 3 through the thread, facilitating quick disassembly and refilling of the gear oil, and the oil quality can also be directly and accurately observed by taking out the liquid level gauge, facilitating judgment of whether the gear oil is blackened and deteriorated.

[0042] In some embodiments of the present application, as shown in Figure 3 As shown, the liquid level gauge is provided with a scale line 601. In this way, the user can accurately read the height of the liquid level, facilitating observation and recording of the change of the liquid level by the user, and providing accurate liquid level measurement and monitoring functions.

[0043] In some embodiments of the present application, the speed reducer liquid level detection device further comprises a plug 7, as shown in Figure 1 As shown, the second end 302 of the oil filling pipe 3 has a second opening, and the plug 7 is plugged into the second opening. In this way, oil discharge is facilitated through the second opening, facilitating maintenance of the speed reducer 2. And the plug 7 is used for closed setting, which can ensure reliable operation of the device and prevent external impurities from entering the internal oil circuit to pollute the gear oil.

[0044] Of course, in other embodiments, the oil level detection device 6 can also be an oil level observation mirror, which is installed on the oil filling pipe 3, and the oil level observation mirror is located between the first opening and the second opening, and the oil level observation mirror is made of transparent material such as acrylic, glass, etc., so that the oil level and oil quality can be observed in real time. At this time, it should be noted that the first opening and the second opening of the oil filling pipe 3 should be installed with the plug 7, so as to control the closing and opening of each opening as needed, facilitating the filling and discharging of the gear oil.

[0045] In some embodiments of the present application, as shown in Figure 2 As shown, one of the plug 7 and the oil filling pipe 3 is provided with a second internal thread, and the other is provided with a second external thread matched with the second internal thread. That is, the plug 7 is provided with the second internal thread, and the second end 302 of the oil filling pipe 3 is correspondingly provided with the matched second external thread; or the second end 302 of the oil filling pipe 3 is provided with the second internal thread, and the plug 7 is correspondingly provided with the matched second external thread. In this way, the plug 7 and the oil filling pipe 3 are screwed together, so that the plug 7 can be screwed out of the oil filling pipe 3 through the thread, facilitating quick disassembly and oil discharge.

[0046] In some embodiments of the present application, as shown in Figure 4As shown, the speed reducer liquid level detection device further comprises a mounting plate 8 and a pipe clamp 9.

It can be understood that the shape of the part of the pipe clamp 9 in contact with the oil feeding and discharging pipe 3 is consistent with the shape of the oil feeding and discharging pipe 3, so as to increase the contact area therebetween, thereby reliably fixing the oil feeding and discharging pipe 3. For example, the oil feeding and discharging pipe 3 is a circular pipe, and the pipe clamp 9 is correspondingly provided with an arc groove matched with the circular pipe. In this way, through the cooperation of the mounting plate 8 and the pipe clamp 9, the installation is facilitated, the operation is convenient, and the assembly efficiency and the structural stability of the device are improved. It should be noted that the pipe clamp 9 is a mature product in the related art, and therefore its specific structure and the like will not be described here again, for example, as shown in Figure 4 As shown, the pipe clamp 9 comprises a pair of opposite pipe clamp halves 901, and the pair of pipe clamp halves 901 are fastened by bolt connection and clamp and fix the oil feeding and discharging pipe 3.

In this way, by arranging a plurality of mounting plates 8 and a plurality of pipe clamps 9, it can be ensured that the pipeline is stably supported at different heights, the stable support and flexible arrangement of the pipeline are realized, and the overall device has higher safety and reliability.

[0049] In some embodiments of the present application, as shown in Figure 4 As shown, the pipe clamp 9 is provided with a first mounting hole, the mounting plate 8 is provided with a second mounting hole 801 opposite to the first mounting hole, and the first mounting hole and the second mounting hole 801 are used for inserting and fastening the fastener 10, which is a bolt or a screw or the like. Among them, at least one of the first mounting hole and the second mounting hole 801 is a waist-shaped hole, for example, as shown in Figure 5 As shown, the second mounting hole 801 is a waist-shaped hole. In this way, the fastener 10 is sequentially inserted through the first mounting hole and the second mounting hole 801 to lock the pipe clamp 9 on the mounting plate 8, thereby realizing reliable fixation of the oil feeding and discharging pipe 3. And by designing the waist-shaped hole and cooperating with the hose, the installation position of the oil feeding and discharging pipe 3 can be adjusted as needed, the installation error and manufacturing error are eliminated, and the assembly and pipeline arrangement are facilitated.
