Problems solved by technology

[0002] The seal of the shaft of the existing mine-used double-chain scraper conveyor is a static seal, which does not rotate with the shaft. It adopts a skeleton seal structure, which is not wear-resistant, and the compensation between the sealing surfaces is poor. When the self-aligning bearing beats, it will cause There is a gap between the sealing surfaces, resulting in oil leakage
The friction force generated by the skeleton seal structure is large, which shortens the service life of the seal and requires frequent replacement of the seal, which affects normal production

Embodiment 1

[0015] Such as Figure 1-2 As shown, a double-chain scraper conveyor seal assembly for mining includes a moving ring sealing sleeve (1) and a static ring sealing sleeve (2). The moving ring sealing sleeve (1) is fixed on a rotating shaft, and the static ring sealing sleeve (2) Press tightly on the moving ring sealing sleeve (1), and the butting surface of the moving ring sealing sleeve (1) and the static ring sealing sleeve (2) is smooth to form a sealing surface. The moving ring sealing sleeve (1) is composed of a lower sealing ring (11), a connecting piece (12), a connecting sleeve (13), a fixed sleeve (14) and a spring (15). The lower sealing ring (11) and the connecting sleeve (13) A connecting piece (12) and a spring (15) are arranged between ), and the lower part of the connecting piece (12) is fixed to the upper part of the connecting sleeve (13) through a fixing sleeve (14). The lower sealing ring (11) is cast from a titanium alloy, and the upper surface of the lower s...

Abstract

The invention relates to a sealing assembly of a mining double-chain scraper conveyer. The sealing assembly of the mining double-chain scraper conveyer comprises a movable ring sealing sleeve and a fixed ring sealing sleeve. The movable ring sealing sleeve is fixed to a rotary shaft. The fixed ring sealing sleeve is tightly pressed on the movable ring sealing sleeve. The butt joint surfaces of the movable ring sealing sleeve and the fixed ring sealing sleeve are smooth and form a sealing surface. The sealing assembly of the mining double-chain scraper conveyer has the beneficial effects that an upper sealing ring and a lower sealing ring are made of titanium alloy through casting, and the upper surface of the upper sealing ring and the upper surface of the lower sealing ring are polished, so that the smoothness is high, the ring sealing performance is good, and the service life is long. A plurality of springs are arranged between the lower sealing ring and a connecting sleeve, so that the compensation force is large, the sealing surfaces between the upper sealing ring and the lower sealing ring are combined more tightly, and the phenomenon of oil leakage is prevented.

Description

Technical field: [0001] The invention relates to a sealing assembly of a double-chain scraper conveyor for mining, which belongs to the technical field of mining machinery. Background technique: [0002] The seal of the shaft of the existing double-chain scraper conveyor for mining is a static seal, which does not rotate with the shaft. It adopts a skeleton sealing structure, which is not wear-resistant and has poor compensation between the sealing surfaces. When the self-aligning bearing beats, it will cause There are gaps between the sealing surfaces, causing oil leakage. The high friction generated by the skeleton seal structure shortens the service life of the seal, and requires frequent replacement of the seal, which affects normal production. Summary of the invention: [0003] The purpose of the present invention is to provide a double-chain scraper conveyor sealing assembly for mining with good sealing performance and long service life. [0004] In order to achieve the abov...
