Description

Technical Field

[0001] The utility model relates to the technical field of mine sawtooth rings, in particular to a mine sawtooth ring which is convenient for disassembly, replacement and installation. Background Technique

[0002] Coal is an essential fuel in daily life. For coal mining, people have invented coal scrapers. The coal scraper uses a chain to connect the scraper to scrape and convey the coal in the earth's crust. The current chains on coal scrapers have problems such as insecure connection, troublesome disassembly, and easy damage. Generally, ordinary open rings are used for chain connection. The force that can be borne after connection is too small, the service life is short, and the replacement is very inconvenient, which affects the coal scraping work. Moreover, if the chain breaks during operation, it may seriously damage the coal scraper.

[0003] The Chinese patent document with the authorization announcement number CN207406707U relates to the field of mine sawtooth rings, in particular to a new type of mine sawtooth ring with high buffering performance. This new type of mine sawtooth ring with high buffering performance splits the sawtooth ring body into a left half ring and a right half ring, and a buffer assembly composed of an installation shell, a limit sliding assembly and a buffer spring assembly is arranged between the two. By respectively arranging a positioning sliding rod one and a positioning sliding rod two on the corresponding sides of the left half ring and the right half ring, and fixedly connecting with the positioning slider inside the installation shell through a connecting convex block, the position of the positioning sliding rod one or the positioning sliding rod two is limited by the positioning slider to improve the structural stability. A spring buffer assembly composed of a buffer spring and a threaded installation part is arranged between the two groups of positioning sliders inside the sliding installation chamber to buffer the sawtooth ring body, thereby improving the buffering performance of the sawtooth ring body.

[0004] The above-mentioned prior art cannot quickly control, adjust, separate, close and install the mine sawtooth ring, and the disassembly, installation and fixation are relatively cumbersome. Therefore, it is necessary to develop a mine sawtooth ring which is convenient for disassembly, replacement and installation. Content of the Utility Model

Inside the locking control mechanism, a first threaded rod and a second threaded rod are respectively installed and fixed. At both ends of the first sawtooth half-ring and the second sawtooth half-ring, there are clamping parts. Inside the clamping parts, there are threaded sliding sleeves. The first sawtooth half-ring and the second sawtooth half-ring move linearly in opposite directions perpendicular to the first threaded rod and the second threaded rod through the threaded sliding sleeves.

Specific implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a mining serrated ring that is convenient for disassembly, replacement, including a first serrated half ring 1 and a second serrated half ring 3. The structure between the first serrated half ring 1 and the second serrated half ring 3 is a detachable structure. The first serrated half ring 1 and the second serrated half ring 3 are connected by a locking control mechanism 2. A first threaded rod 6 and a second threaded rod 11 are respectively installed and fixed inside the locking control mechanism 2. Clamping parts 9 are provided at both ends of the first serrated half ring 1 and the second serrated half ring 3. A threaded sliding sleeve 8 is installed inside the clamping part 9. The first serrated half ring 1 and the second serrated half ring 3 perform linear motion in opposite directions perpendicular to the first threaded rod 6 and the second threaded rod 11 through the threaded sliding sleeve 8.

[0022] Furthermore, a worm gear structure 13 is installed inside the locking control mechanism 2. The center of the surface of the worm gear structure 13 is fixedly connected to the first threaded rod 6 and the second threaded rod 11 respectively through a rotating shaft. A control rod 10 is installed outside the locking control mechanism 2. One end of the control rod 10 is connected to a worm structure 14 through a rotating shaft. The worm structure 14 and the worm gear structure 13 are connected by meshing transmission. The operator holds the control rod 10 and drives the worm structure 14 and the worm gear structure 13 to engage and transmit with each other by rotating the control rod 10, thereby driving the first threaded rod 6 and the second threaded rod 11 to rotate quickly. Since the thread directions on the surfaces of the first threaded rod 6 and the second threaded rod 11 are opposite, the first serrated half ring 1 and the second serrated half ring 3 perform linear motion in opposite directions perpendicular to the first threaded rod 6 and the second threaded rod 11 through the threaded sliding sleeve 8, promoting the first serrated half ring 1 and the second serrated half ring 3 to quickly close and separate.

[0023] Furthermore, limiting plates 5 are provided at both the upper and lower ends of the locking control mechanism 2. The limiting plates 5 are correspondingly connected to the first threaded rod 6 and the second threaded rod 11, which can provide a good limiting effect on the sliding of the threaded sliding sleeve 8. Cover plate structures 12 are provided at both the front and rear ends of the locking control mechanism 2. Fixed guide rails 4 are installed inside the cover plate structures 12. Slider structures 7 are provided on the front and rear end surfaces of the clamping portion 9. The clamping portion 9 vertically slides along the surface of the fixed guide rail 4 through the slider structure 7. By providing the slider structure 7 along the fixed guide rail 4 structure, it can make the first serrated half-ring 1 and the second serrated half-ring 3 more stable and safe during sliding adjustment, and no shaking or deviation phenomenon will occur.

[0024] Working principle: During use, the first serrated half-ring 1 and the second serrated half-ring 3 are connected by the locking control mechanism 2. The first threaded rod 6 and the second threaded rod 11 are respectively installed and fixed inside the locking control mechanism 2. Clamping portions 9 are provided at both ends of the first serrated half-ring 1 and the second serrated half-ring 3. Threaded sliding sleeves 8 are installed inside the clamping portions 9. The operator holds the control rod 10 and drives the worm structure 14 and the worm gear structure 13 to engage and drive each other by rotating the control rod 10, thereby driving the first threaded rod 6 and the second threaded rod 11 to rotate rapidly. Since the thread directions on the surfaces of the first threaded rod 6 and the second threaded rod 11 are opposite, the first serrated half-ring 1 and the second serrated half-ring 3 make opposite-direction perpendicular linear motions along the first threaded rod 6 and the second threaded rod 11 through the threaded sliding sleeves 8, causing the first serrated half-ring 1 and the second serrated half-ring 3 to quickly close and separate, having the advantage of convenient installation and disassembly control.
