Description

Technical Field

[0001] This application relates to the field of hydraulic cylinder technology, specifically a protective housing for monitoring oil leakage in hydraulic cylinders. Background Technology

[0002] A hydraulic cylinder is an actuator that converts hydraulic energy into mechanical energy. It uses the pressure of hydraulic oil to drive a piston rod to move, achieving linear reciprocating motion or oscillation. With the widespread application of hydraulic cylinders, in order to improve the stability of hydraulic cylinders, it is necessary to monitor and record the hydraulic oil in the hydraulic cylinder. Therefore, a protective shell for monitoring hydraulic cylinder oil leakage is needed.

[0003] Chinese patent CN221628568U discloses an anti-collision hydraulic cylinder, which includes a protective shell body. The hydraulic cylinder is installed inside the protective shell body. Under the action of the anti-collision spring, a buffer force can be formed between the protective shell body and the hydraulic cylinder to prevent the hydraulic cylinder from being damaged under impact force and causing hydraulic oil leakage. This increases the anti-collision effect of the device and solves the problem of lack of buffer effect.

[0004] However, while the aforementioned device protects the hydraulic cylinder through the protective shell, it makes it difficult to monitor and maintain the hydraulic cylinder when oil leakage occurs, which can easily lead to damage to the hydraulic cylinder over time. Therefore, we propose a protective shell for monitoring hydraulic cylinder oil leakage. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this application provides a protective housing for monitoring hydraulic cylinder oil leakage, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution To achieve the above objectives, this application provides the following technical solution: a protective shell for monitoring hydraulic cylinder oil leakage, comprising a base, a monitoring mechanism, a protective mechanism, and a hydraulic cylinder body. The monitoring mechanism is provided on the upper surface of the base, and the hydraulic cylinder body is located inside the monitoring mechanism. The monitoring mechanism includes an adjustment frame and a photoelectric water immersion sensor for monitoring the hydraulic cylinder body. The photoelectric water immersion sensor is located inside the adjustment frame, and the adjustment frame is used to drive the photoelectric water immersion sensor to contact the hydraulic cylinder body.

[0007] By adopting the above technical solution, the photoelectric water immersion sensor can quickly respond to oil leakage. Then, the adjustment frame can facilitate contact between the photoelectric water immersion sensor and the hydraulic cylinder body, which is convenient for timely monitoring of oil leakage in the hydraulic cylinder body. If oil leakage occurs in the hydraulic cylinder body, it can be detected and alarmed by the photoelectric water immersion sensor.

[0008] Preferably, the monitoring mechanism further includes a protective shell located on the upper surface of the base. An adjustment groove is fixedly installed on one side of the protective shell. The adjustment frame is slidably connected inside the adjustment groove. A first bolt is threaded to the front side of the adjustment groove. The first bolt extends into the adjustment groove and contacts the adjustment frame. A sealing ring gasket is fixedly installed on one side of the adjustment frame. The hydraulic cylinder body is located inside the protective shell. The sealing ring gasket contacts the oil inlet of the hydraulic cylinder body. The photoelectric water immersion sensor is fixedly installed at the inner bottom of the adjustment frame. A voice alarm is fixedly installed on one side of the adjustment groove. The photoelectric water immersion sensor and the voice alarm are electrically connected.

[0009] By adopting the above technical solution, the protective shell protects the hydraulic cylinder body. Then, the first bolt drives the adjusting frame to slide inside the adjusting groove. The sealing ring gasket on the linkage side of the adjusting frame contacts the oil inlet of the hydraulic cylinder body, thereby facilitating the sealing and isolation of the oil inlet of the hydraulic cylinder body. In case of oil leakage, it can be monitored in real time by the photoelectric water immersion sensor at the bottom of the adjusting frame. When the photoelectric water immersion sensor detects the leaking oil, it will issue an alarm through the voice alarm.

[0010] Preferably, a connecting pipe is provided through the front side of the adjusting groove, one end of the connecting pipe is connected to the oil inlet of the hydraulic cylinder body, a pressure gauge is fixedly installed on the outer wall of the connecting pipe, and the other end of the connecting pipe is connected to an oil supply pipe.

[0011] By adopting the above technical solution, the pressure value of the oil supplied to the hydraulic cylinder body can be easily understood through the pressure gauge on the connecting pipe, so that the pressure situation can be monitored in real time, and maintenance operations can be easily carried out when abnormalities occur.

[0012] Preferably, the upper surface of the bottom of the protective shell is threaded with a plurality of second bolts, one end of which extends to the bottom of the protective shell and is threadedly fastened between the bottom of the protective shell and the base.

[0013] By adopting the above technical solution, the second bolt facilitates the installation of the protective shell and the base, thereby improving the stability of the protective shell.

[0014] Preferably, the protective mechanism includes multiple anti-collision bars, which are fixedly installed on the outer side wall of the protective shell. Two sliding plates are fixedly installed on the top of the multiple anti-collision bars, and the two sliding plates are arranged opposite to each other. A slider is slidably connected inside the two sliding plates. A sealing cover is fixedly installed on one side of the slider. Multiple third bolts are threadedly connected to the upper surface of the two sliding plates, and one end of the multiple third bolts extends into the interior of the two sliding plates and is threadedly fixed between the bolts and the slider.

[0015] By adopting the above technical solution, the anti-collision rod can improve the anti-collision effect of the protective shell. Then, the slider slides in the groove plate on the anti-collision rod. The slider drives the sealing cover to close, preventing external dust or garbage from entering the interior of the protective shell. Finally, the slider in the groove plate is fixed by the third bolt, thereby preventing the slider from becoming loose.

[0016] Preferably, a silicone sealing sleeve is fixedly installed on the upper surface of the sealing cover, and the silicone sealing sleeve is adapted to the piston rod of the hydraulic cylinder body.

[0017] By adopting the above technical solution, the sealing cover drives the silicone sealing sleeve to contact the piston rod of the hydraulic cylinder body, reducing the amount of dust from the outside adhering to the piston rod of the hydraulic cylinder body and thus preventing it from entering the interior of the hydraulic cylinder body and causing accumulation.

[0018] (III) Beneficial Effects This application provides a protective housing for monitoring hydraulic cylinder oil leakage. It has the following beneficial effects: 1.

If oil leakage occurs in the hydraulic cylinder body, it can be detected and alarmed by the photoelectric water immersion sensor, effectively improving the safety of the hydraulic cylinder body.

[0019] 2. This protective housing for monitoring hydraulic cylinder oil leakage uses the cooperation of the sliding plate, slider and sealing cover of the protective mechanism. The slider slides in the sliding plate on the anti-collision bar, and the slider drives the sealing cover to close, thereby preventing external dust or garbage from entering the interior of the protective housing.

[0022] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1 and Figure 2 This application provides a protective shell for monitoring hydraulic cylinder oil leakage, including a base 1, a monitoring mechanism 2, a protective mechanism 3, and a hydraulic cylinder body 4. The monitoring mechanism 2 is provided on the upper surface of the base 1, and the hydraulic cylinder body 4 is located inside the monitoring mechanism 2. The monitoring mechanism 2 includes an adjustment frame 203 and a photoelectric water immersion sensor 207 for monitoring the hydraulic cylinder body 4. The photoelectric water immersion sensor 207 is located inside the adjustment frame 203, and the adjustment frame 203 is used to drive the photoelectric water immersion sensor 207 to contact the hydraulic cylinder body 4.

[0024] The internal photoelectric water immersion sensor 207 is moved and adjusted by the adjusting bracket 203, so that the photoelectric water immersion sensor 207 can make contact with the hydraulic cylinder body 4. Then, the photoelectric water immersion sensor 207 monitors the oil inlet of the hydraulic cylinder body 4. Once the hydraulic cylinder body 4 leaks oil, it can be detected and alarmed by the photoelectric water immersion sensor 207, thereby effectively improving the safety of the hydraulic cylinder body 4.

[0025] Reference Figure 2 and Figure 3 In one aspect of this embodiment, the monitoring mechanism 2 further includes a protective shell 201 located on the upper surface of the base 1. An adjustment groove 202 is fixedly installed on one side of the protective shell 201. An adjustment frame 203 is slidably connected inside the adjustment groove 202. A first bolt 205 is threadedly connected to the front side of the adjustment groove 202. The first bolt 205 extends into the interior of the adjustment groove 202 and contacts the adjustment frame 203. A sealing ring gasket 204 is fixedly installed on one side of the adjustment frame 203. The hydraulic cylinder body 4 is located inside the protective shell 201. The sealing ring gasket 204 contacts the oil inlet of the hydraulic cylinder body 4. A photoelectric water immersion sensor 207 is fixedly installed at the inner bottom of the adjustment frame 203. A voice alarm 210 is fixedly installed on one side of the adjustment groove 202. The photoelectric water immersion sensor 207 and the voice alarm 210 are electrically connected.

[0026] A connecting pipe 206 is provided through the front side of the adjusting groove 202. One end of the connecting pipe 206 is connected to the oil inlet of the hydraulic cylinder body 4. A pressure gauge 208 is fixedly installed on the outer wall of the connecting pipe 206. The other end of the connecting pipe 206 is connected to an oil supply pipe 209.

[0027] The upper surface of the bottom of the protective shell 201 is threaded with a plurality of second bolts 211, one end of which extends to the bottom of the protective shell 201 and is threadedly fastened to the base 1.

[0028] The protective shell 201 is installed on the base 1 and then tightened with the second bolt 211, thus facilitating the protection of the hydraulic cylinder body 4 by the protective shell 201. After installation, the first bolt 205 is turned, causing the adjusting frame 203 to slide inside the adjusting groove 202. The sealing ring gasket 204 on the linkage side of the adjusting frame 203 comes into contact with the oil inlet of the hydraulic cylinder body 4, allowing the photoelectric water immersion sensor 207 at the bottom of the adjusting frame 203 to monitor the oil inlet of the hydraulic cylinder body 4 and detect oil leaks in a timely manner. When the photoelectric water immersion sensor 207 detects leaking oil, it will sound an alarm through the electrically connected voice alarm 210, facilitating timely maintenance or replacement. The oil supply pipe 209 at one end of the connecting pipe 206 facilitates the supply of oil to the hydraulic cylinder body 4, and the pressure gauge 208 on the connecting pipe 206 allows for monitoring of the oil pressure value supplied to the hydraulic cylinder body 4, enabling real-time monitoring of the pressure and facilitating maintenance in case of abnormalities.

[0029] Reference Figure 1 and Figure 4 In one aspect of this embodiment, the protective mechanism 3 includes a plurality of anti-collision bars 301, which are fixedly installed on the outer side wall of the protective shell 201. Two sliding plates 302 are fixedly installed on the top of the plurality of anti-collision bars 301. The two sliding plates 302 are arranged opposite to each other. A slider 303 is slidably connected inside the two sliding plates 302. A sealing cover 305 is fixedly installed on one side of the slider 303. A plurality of third bolts 304 are threadedly connected to the upper surface of the two sliding plates 302. One end of the plurality of third bolts 304 extends into the interior of the two sliding plates 302 and is threadedly fixed between them and the slider 303.

[0030] A silicone sealing sleeve 306 is fixedly installed on the upper surface of the sealing cover 305, and the silicone sealing sleeve 306 is adapted to the piston rod of the hydraulic cylinder body 4.

[0031] The anti-collision bar 301 enhances the anti-collision effect of the protective shell 201, thereby effectively protecting the hydraulic cylinder body 4. Subsequently, the slider 303 slides within the slide plate 302 on the anti-collision bar 301. The slider 303 drives the sealing cover 305 to close. The sealing cover 305, in conjunction with the silicone sealing sleeve 306, contacts the piston rod of the hydraulic cylinder body 4, thereby facilitating the sealing operation of the hydraulic cylinder body 4 and preventing external dust or debris from entering the interior of the protective shell 201. Finally, the slider 303 within the slide plate 302 is fixed by the third bolt 304.

[0032] All electrical devices in this plan are powered by an external power source.

[0033] Working principle: During use, tightening the first bolt 205 causes the adjusting frame 203 to slide inside the adjusting groove 202. The sealing ring gasket 204 on the linkage side of the adjusting frame 203 comes into contact with the oil inlet of the hydraulic cylinder body 4, thus facilitating the monitoring of the oil inlet of the hydraulic cylinder body 4 by the photoelectric water immersion sensor 207 at the bottom of the adjusting frame 203. When the photoelectric water immersion sensor 207 detects leaking oil, an alarm is triggered by the electrically connected voice alarm 210. The oil inlet pipe 209 at one end of the connecting pipe 206 facilitates the flow of oil into the hydraulic cylinder body 4. The oil is supplied through the pressure gauge 208 on the connecting pipe 206, which allows for real-time monitoring of the oil pressure supplied to the hydraulic cylinder body 4. Subsequently, the slider 303 slides within the slide plate 302 on the anti-collision bar 301. The slider 303 drives the sealing cover 305 to close, and the sealing cover 305, in conjunction with the silicone sealing sleeve 306, contacts the piston rod of the hydraulic cylinder body 4, preventing external dust or debris from entering the interior of the protective shell 201. Finally, the slider 303 within the slide plate 302 is fixed by the third bolt 304.

[0034] This design addresses issues such as hydraulic oil leakage detection encountered in the comparative documentation. Through the cooperation of monitoring mechanism 2, it enables oil leakage detection of the hydraulic cylinder body 4. The adjusting bracket 203 of monitoring mechanism 2 drives the photoelectric water immersion sensor 207 to monitor the oil inlet of the hydraulic cylinder body 4. If oil leakage occurs, the leaking hydraulic oil will contact the photoelectric water immersion sensor 207, triggering an alarm via voice alarm 210. This facilitates maintenance and inspection, significantly improving the safety of the hydraulic cylinder body 4 during operation. It also prevents hydraulic oil leakage from damaging other components within the equipment, further ensuring the safety and stability of the hydraulic cylinder body 4 during long-term use.
