Description

Technical Field

[0001] This utility model relates to the field of backstop technology, specifically a clutch-type backstop. Background Technology

[0002] A backstop is a machine used to prevent a conveyor from reversing when it stops under load. In order to prevent the inclined belt conveyor from reversing or slipping when it stops under load, a backstop or braking device is added depending on the specific situation after calculating the braking torque.

[0003] For example, Chinese Patent Application No. 202323080102.2 discloses a clutch-type backstop, including a backstop frame with a backstop cavity and a through hole at the top; a rotating ring rotatably installed in the backstop cavity and connected to an external drive shaft; several backstop components for ensuring that the rotating ring can only rotate unidirectionally in the backstop cavity, the backstop components including a backstop groove disposed on the inner peripheral wall of the backstop cavity; a mounting groove disposed on the outer peripheral wall of the rotating ring; and a backstop floating block, one end of which is rotatably installed in the mounting groove via a hinge. In daily use, by adopting the above technical solution, the device is small in size, convenient for installation in narrow spaces, and since each backstop component is located in the backstop cavity, it is difficult for debris to enter, thus avoiding abnormal locking of each backstop component due to the influence of debris.

[0004] However, during long-term operation, the aforementioned backstop may accumulate dust, oil, metal shavings, and other contaminants inside, requiring internal cleaning and maintenance, but disassembly is cumbersome. Therefore, those skilled in the art have provided a clutch-type backstop to solve the problems mentioned in the background art. Utility Model Content

[0024] The auxiliary maintenance mechanism 4 includes a maintenance housing 41. A fixed semi-threaded post 42 is fixed to the outer side of the maintenance housing 41. A limit groove 43 is formed on the outer wall of the fixing frame 2. An anti-detachment guide block 44 is slidably connected to the fixing frame 2 through the limit groove 43. An installation sleeve 45 is fixed to the top of the anti-detachment guide block 44. A positioning semi-threaded post 46 is fixed to the outer side of the installation sleeve 45. An installation pad 47 is movably sleeved on the outer sides of the positioning semi-threaded post 46 and the fixed semi-threaded post 42. A cast iron nut 48 is threadedly connected to the outer sides of the fixed semi-threaded post 42 and the positioning semi-threaded post 46. A maintenance through groove is formed on the outer wall of the clutch-type backstop body 1. The size of the maintenance through groove is adapted to the size of the maintenance housing 41. The radius of the positioning semi-threaded post 46 is equal to the radius of the fixed semi-threaded post 42. A groove adapted to the size of the maintenance housing 41 is formed inside the installation sleeve 45. The clutch-type backstop body 1 is a device used to prevent the conveyor from reversing when it stops under load. Meanwhile, after prolonged use, dust, oil, metal shavings, and other contaminants may accumulate inside the clutch-type backstop body 1. When cleaning and maintaining the inside of the clutch-type backstop body 1, the cast iron nut 48 on the outside of the positioning half-threaded post 46 and the fixing half-threaded post 42 can be rotated. After removing the cast iron nut 48 and the mounting pad 47, the fixing between the mounting sleeve 45 and the maintenance housing 41 can be released. Then, the anti-detachment guide block 44 can be pushed down to release the limiting obstruction of the maintenance housing 41 by the mounting sleeve 45, making it easier for the user to disassemble the maintenance housing 41. This removes the obstruction on the outside of the clutch-type backstop body 1 and provides a direct and quick way to clean and maintain the inside of the clutch-type backstop body 1. It is not necessary to disassemble the entire outer shell of the clutch-type backstop body 1 or completely remove it from the shaft.

The clutch-type backstop body 1 is a device used to prevent the conveyor from reversing when it stops under load. After prolonged use, dust, oil, metal shavings, and other contaminants may accumulate inside the clutch-type backstop body 1. For internal cleaning and maintenance, the positioning half-threaded post 46 and the cast iron nut 48 on the outside of the fixing half-threaded post 42 can be rotated. After removing the cast iron nut 48 and the mounting pad 47, the fixing between the mounting sleeve 45 and the maintenance housing 41 is released. Then, the anti-detachment guide block 44 is pushed downwards to release the limiting obstruction of the mounting sleeve 45 on the maintenance housing 41, facilitating the user to disassemble the maintenance housing 41. This removes the obstruction on the outside of the clutch-type backstop body 1 and provides a direct and quick channel for internal cleaning and maintenance, eliminating the need for... By disassembling the entire outer shell of the clutch-type backstop body 1 or completely removing it from the shaft, maintenance personnel can easily disassemble the maintenance housing 41 to directly observe the working status and cleanliness of the internal core components and perform necessary cleaning and wiping. With the reinforcement mechanism 5 in place, after the clutch-type backstop body 1 and the fixing frame 2 are fixedly connected, the corresponding surface of the fixing block 54 on the outside of the clutch-type backstop body 1 fits against the fixing frame 2. Then, the anti-disengagement slider 52 is moved to drive the reinforcement sleeve 53 to move, allowing the reinforcement sleeve 53 to be movably sleeved on the outside of the fixing threaded post 55. Then, the washer 56 is movably sleeved on the outside of the fixing threaded post 55, and the metal nut 57 is threadedly connected to the fixing threaded post 55, which conveniently completes the fixation between the reinforcement sleeve 53 and the fixing block 54, thereby strengthening the connection stability between the clutch-type backstop body 1 and the fixing frame 2 and ensuring the stable assembly of the clutch-type backstop body 1.
