A cleaning component is provided inside the vertical oil pipe. The cleaning component includes an annular fixing frame located in the upper part of the vertical oil pipe and fitted therewith. An operating rod is connected to the top center of the annular fixing frame and is provided through the top of the vertical oil pipe. Two support rods are symmetrically connected to the bottom two sides of the annular fixing frame. Each support rod is provided with a scraping rubber strip on its outer side, so that the cleaning component can be rotated to enter the visible area and cooperate with the inner side of the viewing window to scrape off oil stains, and can be rotated from the visible area to the non-visible area.

[0006] The top side of the vertical oil pipe is provided with a pressure stabilizing hole that communicates with the outside. The viewing window is provided with an oil level line, and each oil level line is provided with a magnetic induction scale bar to cooperate with the magnetic induction float ball in the vertical oil pipe to detect the oil level. The oil level signal can be remotely transmitted through an electronic sensor.

[0007] Preferably, the inner side of the viewing window is provided with an anti-oil coating, which can reduce the probability of oil adhesion and thus ensure that the viewing window is clear and observable for a longer period of time.

[0008] Preferably, the vertical oil pipe is provided with a viewing window on the front and rear sides respectively. The two viewing windows are symmetrically arranged, which provides better lighting and makes it easier to clearly observe the oil level.

[0009] Preferably, the vertical oil pipe is also provided with a detachable protective cover, which can achieve a certain dustproof and protective function in harsh environments and prevent wear and tear on the viewing window.

[0010] Preferably, the vertical oil pipe includes a circular pipe, the viewing window is disposed on the circular pipe, the top of the circular pipe is threaded to a cap, and the cleaning component is located on the cap via two nuts at the upper and lower limits. The cleaning component is connected to the cap, allowing the viewing window to be cleaned in a suspended state, which is more convenient and smooth. In addition, it can be removed and installed along with the cap.

[0011] Preferably, a hand lever is threadedly connected to the side of the operating rod outside the vertical oil pipe for easier rotation.

[0012] The advantages of this utility model using the above-mentioned technical solution are: the oil level observation device allows for good observation of the gearbox oil level through the viewing window; the cleaning component, in conjunction with the vertical oil pipe, allows for periodic cleaning of the inside of the viewing window as needed, ensuring that the oil level is always clearly observable; and the combination of the magnetic induction scale bar, magnetic induction float, and electronic sensor enables remote monitoring when on-site observation is inconvenient, making it relatively safe and reliable.

Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-4As shown, in this embodiment, the oil level observation device for the hoist gate opener gearbox includes an external vertical oil pipe 1, which is connected to the gearbox through a pipe during application. The side of the vertical oil pipe 1 is provided with a viewing window 101 to form a visible area and a non-visible area around the vertical oil pipe 1. A cleaning component 2 is provided inside the vertical oil pipe 1. The cleaning component 2 includes an annular fixing frame 201 located in the upper part of the vertical oil pipe 1 and matching it. An operating rod 202 is connected to the top center of the annular fixing frame 201 and is provided with a rod 202 that passes through the top of the vertical oil pipe 1. Two support rods 203 are symmetrically connected to the bottom two sides of the annular fixing frame 201. Each support rod 203 is provided with a scraping rubber strip 204 on the outside, so that the cleaning component 2 can be rotated to enter the visible area and cooperate with the inside of the viewing window 101 to scrape off oil stains, and rotated from the visible area to the non-visible area for placement.

[0020] The top side of the vertical oil pipe 1 is provided with a pressure stabilizing hole 102 that communicates with the outside. The viewing window 101 is provided with an oil level line 103. Each oil level line 103 is provided with a magnetic induction scale bar to cooperate with the magnetic induction float 3 located in the vertical oil pipe 1 to detect the oil level and to remotely transmit the oil level signal through an electronic sensor.

[0021] Working Principle: If the hoist operates in a favorable environment and frequent on-site observation is required, the oil level in the vertical oil pipe 1 can be directly observed through the viewing window 101. When cleaning the viewing window 101 is necessary, the cleaning component 2 is manually rotated. As it rotates, the scraper strip 204 scrapes away the oil residue adhering to the viewing window 101 and hides it in a non-visible area to avoid affecting oil level observation. When the hoist operates in a harsh environment and on-site observation is inconvenient, the detected oil level signal can be remotely transmitted through the combination of a magnetic induction scale strip, a magnetic induction float, and an electronic sensor, enabling remote monitoring, which is convenient and reliable.

[0022] In one embodiment, the inner side of the viewing window 101 is provided with an anti-oil coating, which can reduce the probability of oil adhesion and thus ensure that the viewing window is clear and observable for a longer period of time.

[0023] In one embodiment, the vertical oil pipe 1 is provided with a viewing window 101 on the front and rear sides respectively. The two viewing windows are symmetrically arranged, which provides better lighting and makes it easier to clearly observe the oil level.

[0024] In one embodiment, the vertical oil pipe 1 is further provided with a detachable protective cover 4, which can be fastened to the outside of the vertical oil pipe to achieve a certain dustproof and protective function when it is in a harsh environment, and to prevent wear and tear on the viewing window.

[0025] In one embodiment, the vertical oil pipe 1 includes a circular pipe, the viewing window 101 is disposed on the circular pipe, the top of the circular pipe is threadedly connected to the cap 104, and the cleaning component 2 is located on the cap 104 via two nuts at the upper and lower limits. The cleaning component 2 is limited to the cap and can rotate in a suspended state to clean the viewing window more smoothly. In addition, it can be removed and installed along with the cap 104.

[0026] In one embodiment, a hand lever 205 is threadedly connected to the side of the operating lever 202 outside the vertical oil pipe 1, making it easier to rotate.

[0027] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.
