The invention discloses a joint clamping buckle for a tractive rigging of intelligent equipment. The joint clamping buckle is used on a tractive chain of the intelligent equipment, carries out skid and wear resistance on a connecting point of a hoisting ring, separates connecting and fitting positions of the hoisting ring for protection and can reduce wear. The joint clamping buckle is a wearproofliner clamping buckle and is characterized in that an arc shaped upper clamping groove is formed in the upper side face of a main body buckle; an arc shaped lower clamping groove is formed in the lower side face of the main body buckle; the central axis of the upper clamping groove is perpendicular to that of the lower clamping groove; a plurality of friction strips are arranged on the groove wall of the upper clamping groove at equal intervals and extend in the arc shape direction of the upper clamping groove; a plurality of friction strips are arranged on the groove wall of the lower clamping groove at equal intervals and extend in the arc shape direction of the lower clamping groove; two fixed broached grooves are formed in the upper side face of the main body buckle and are formed inthe two sides of the opening of the upper clamping groove separately; and two fixed broached grooves are formed in the lower side face of the main body buckle and are formed in the two sides of the opening of the lower clamping groove separately.

The invention provides a mobile filling device for solid hazardous chemical substances. The mobile filling device mainly solves the problem that the solid hazardous chemical substances float outwards in the filling process and comprises a first tank body, a crotch type distribution pipe, a rotating hub and a sieve plate, wherein the crotch type distribution pipe, the rotating hub and the sieve plate are sequentially arranged from top to bottom; a sealing cover is arranged on an opening of the first tank body, the crotch type distribution pipe adds liquid mixing agents, the rotating hub is arranged in the first tank body transversely, blades are arranged on the outer side of the rotating hub, and a crank arranged on the external side drives the blades to rotate along with the rotating hub. In the specific filling process, a packaging bag containing the solid hazardous chemical substances is placed into the first tank body through a pulling rope, the rotating hub is driven after the sealing cover seals the first tank body, the blades cut the packaging bag, the solid hazardous chemical substances automatically fall into the first tank body, and then the crotch type distribution pipe carries out washing. According to the invention, the sealed filling mode is adopted, the solid hazardous chemical substances can be effectively prevented from floating outwards, and therefore harm to operation staff and pollution to the environment can be effectively reduced.

The invention relates to an oil pressure type automatic extension grinding rod for grinding an inner diameter and a using method of the oil pressure type automatic extension grinding rod.
