Abstract

The utility model relates to the technical field of mud scraping equipment, and provides a mud scraping plate shutdown protection device and a mud scraping machine. The rotating component is pressed on the load rope of the mud scraper to tension the load rope. The emergency stop trigger is disposed on the rotating assembly and is configured to be coupled to the mobile device. The emergency stop trigger is used for detecting the rotation angle of the rotating assembly and triggering an emergency stop switch of the moving device according to the rotation angle of the rotating assembly. According to the mud scraping plate stopping protection device, the sudden stop trigger is arranged on the rotating assembly, and can detect the rotating angle of the rotating assembly relative to the moving device, and when the mud scraping plate contacts the bottom of the pool due to excessive looseness of the load rope, the sudden stop switch of the moving device is triggered according to the rotating angle of the rotating assembly, so that the moving device is suddenly stopped.

Description

Mud scraping plate shutdown protection device and mud scraping machine Technical Field The utility model relates to the technical field of mud scraping equipment, in particular to a mud scraping plate shutdown protection device and a mud scraping machine. Background In the related art, sludge is easily deposited at the bottom of a secondary sedimentation tank of a sewage plant, and a sludge scraper is required to scrape the sludge at the bottom of the tank. Generally, a sewage plant uses a travelling crane type mud scraper, and drives a mud scraper at the bottom to push mud to one side of a sedimentation tank through travelling crane, and then drives the mud scraper to return to the other side, so that the mud scraper is reciprocated. When the mud scraper pushes sludge to one side, the mud scraper needs to be kept in a grounded state, and when the mud scraper returns to the other side, the travelling crane needs to pull the mud scraper through a load-bearing rope (usually a steel wire rope) so that the mud scraper is completely suspended. If the load rope is loosened or broken in the returning process, the mud scraping plate is contacted, and under the condition, the running vehicle continues to move, so that the whole mud scraping machine is possibly subjected to serious faults such as derailment, tilting, side turning and the like. Disclosure of utility model The utility model provides a mud scraper shutdown protection device and a mud scraper, which are used for solving the problem that in the prior art, in the returning process of the mud scraper, a load rope is loosened or broken to cause the mud scraper to contact the bottom of a pool, and under the condition, the continuous movement of a travelling crane can possibly cause serious faults such as derailment, inclination, side turning and the like of the whole mud scraper.
