Description

Technical Field

[0001] The utility model relates to the technical field of floating oil seal detection, in particular to a floating oil seal detection device. Background Art

[0002] Floating oil seal is a kind of dynamic seal. It has super sealing performance in harsh working environments such as coal powder, mud, water vapor, etc. It is a compact mechanical seal, mainly used in low-speed and heavy-load occasions. It has the advantages of wear resistance, automatic compensation after end face wear, reliable operation, simple structure, etc. It is widely used in coal mining machinery, such as scraper conveyor head (tail) sprocket assembly, tunneling machine loading mechanism and cantilever section, continuous coal mining machine left and right cutting drum and reducer, etc. The sealing of floating oil seals needs to be tested during the production and processing process.

[0003] A Chinese patent discloses a floating oil seal sealing detection device (authorization announcement number: CN211626823U), which is provided with a screw rod, a screw rod nut and the relative positions between the moving plate and the arc plate.

[0004] They cooperate with each other, because the rotation directions of the two screw nuts are opposite, the forward and reverse rotation of the handle drives the corresponding movable plate and the arc plate to move at the same time, which makes it easier to clamp and fix the floating oil seal, making it more convenient to use. However, the above-mentioned arc plate is located above the water tank and cannot move up and down, so the downward movement of the floating oil seal between the arc plates is limited. When the water level in the water tank is low, it is impossible to ensure that the bottom of the floating oil seal is in contact with the water in the water tank, which has certain shortcomings.

The floating oil seal can be clamped by two relatively distributed limiting mechanisms 5, and the clamped floating oil seal can move longitudinally, which is convenient to move it into the water tank 3 for sealing detection. Compared with the traditional method, the downward displacement of the floating oil seal can be controlled. When the water level in the water tank 3 is relatively low, it can also ensure that the bottom of the floating oil seal is in contact with the water in the water tank 3.

[0021] Above the water tank 3, a drying mechanism 6 is installed. The drying mechanism 6 includes a motor 61, a vertical rod 62, and a hollow tube 63. The motor 61 is fixedly connected to the top of the mounting plate 4, and the driving end of the motor 61 penetrates through the mounting plate 4 and is fixedly connected to the vertical rod 62. A hollow tube 63 is slidably sleeved at the bottom of the vertical rod 62. A second bolt 64 is threadedly connected to the hollow tube 63, and a sealing plate 65 is fixedly connected to the bottom end of the hollow tube 63. A first sealing ring 66 and a second sealing ring 67 are fixedly connected to the bottom of the sealing plate 65. The diameter of the second sealing ring 67 is smaller than that of the first sealing ring 66, and the thickness of the second sealing ring 67 is the same as that of the first sealing ring 66. The bottoms of the first sealing ring 66 and the second sealing ring 67 are on the same horizontal line, and the central points of the second sealing ring 67 and the first sealing ring 66 are on the same vertical line. The air outlet end of the air pump 21 is fixedly communicated with the first sealing ring 66 through a hose. The drying mechanism 6 can drive the sealing plate 65, the first sealing ring 66, and the second sealing ring 67 to rotate, facilitating timely drying of the water stains attached to the sealing plate 65, the first sealing ring 66, and the second sealing ring 67, and preventing problems such as rusting of the sealing plate 65.

[0022] Working principle: When using this device, fill water into the water tank 3, place the floating oil seal between the two arc-shaped plates 57, and then control the two electric push rods 54 to extend. At this time, the two baffle plates 56 can be driven to move relatively, and then the two arc-shaped plates 57 can be driven to move relatively, so as to clamp the floating oil seal. Then loosen the two first bolts 52, and hold the two telescopic plates 53 and move them downward. At this time, the clamped floating oil seal can be driven to move downward until the bottom of the floating oil seal contacts the water body in the water tank 3. Then tighten the two first bolts 52, and then loosen the second bolt 64, and hold the hollow tube 63 and move it downward. At this time, the sealing plate 65, the first sealing ring 66 and the second sealing ring 67 can be driven to move downward. At this time, the second sealing ring 67 contacts the inner end face of the floating oil seal, and the first sealing ring 66 contacts the outer end face of the floating oil seal. When the first sealing ring 66 moves downward, it should be ensured that the hose between the air pump 21 and the first sealing ring 66 is always located above the floating oil seal to avoid being unable to inflate in the subsequent process. At this time, the sealing plate 65 is located above the floating oil seal. Then tighten the second bolt 64 and turn on the air pump 21. At this time, the gas can enter the cavity between the first sealing ring 66 and the second sealing ring 67 through the hose. Then just observe whether there are bubbles in the water tank 3 and repeat the above steps to complete the sealing detection work of the floating oil seal. When the detection is completed, loosen the second bolt 64, and hold the hollow tube 63 and move it upward. At this time, the first sealing ring 66 and the second sealing ring 67 can be removed from the floating oil seal. When the first sealing ring 66 and the second sealing ring 67 are adjusted to the ideal height, tighten the second bolt 64 and control the motor 61 to work. At this time, the sealing plate 65, the first sealing ring 66 and the second sealing ring 67 can be driven to rotate, which is convenient for drying the water stains attached to the sealing plate 65, the first sealing ring 66 and the second sealing ring 67 and preventing problems such as rust on the sealing plate 65.
