[0016] Through the above technical scheme, the front end of the connecting plate is arranged on the front surface of the boss sliding box, so that the connecting plate can effectively transmit the movement state of the limiting boss to the connecting shaft outside the boss sliding box, ensure that the movement state in the limiting device can be accurately transmitted, so as to control other related parts, and make the whole limiting device better integrate into the overall operation system of the slag flushing crane.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] The limiting boss is arranged, when the slag is grabbed, the shaft of the roller is axially connected, when the limiting is extruded, the connecting shaft is first contacted, the connecting shaft is extruded, the limiting boss drives the connecting shaft to move upward, the limiting boss extrudes the buffer spring, and a buffering force is given to the limiting boss. Since the connecting shaft is connected with the limiting boss, the connecting shaft is synchronously buffered when being extruded by the roller, the whole limiting is protected, and the operation is more stable.
