This utility model provides a pile head reinforcement structure for construction in hard rock formations, including a steel sleeve, a grouting structure disposed between the steel sleeve and the outer surface of the pile head, a shear structure for forming a mechanical interlocking effect between the pile head and the steel sleeve, an anchoring structure for reliable connection with the pile body, a pressure-bearing flange disposed at the bottom of the steel sleeve, and a reinforcing rib structure arranged on the outer wall of the steel sleeve. The steel sleeve is fitted around the periphery of the precast pile head, and the grouting structure fills the space between the inner wall of the steel sleeve and the outer surface of the pile head and is fixed to both. This pile head reinforcement structure for construction in hard rock formations solves the problem that, due to the lack of effective structural reinforcement and circumferential restraint measures for precast pile heads in related technologies, pile heads are prone to spalling, crushing, cracking, and other damage under high loads and impact conditions.

The utility model discloses an overhead power transmission hoisting device, which belongs to the technical field of power transmission engineering and comprises a traveling base, a hoisting winch assembly, a front top plate, a telescopic beam, a front pressing frame and a locking bolt. The front top plate is fixed to the front portion of the walking base and forms a vertical end face abutting against a tower foundation pile, the telescopic beams are installed on the two sides of the upper portion of the front top plate in a bilateral symmetry mode, the front pressing frame is installed at the front ends of the telescopic beams, and the front top plate, the telescopic beams and the front pressing frame form a door-shaped frame structure with the adjustable opening degree. And the locking bolts are used for clamping the tower foundation piles on the inner side of the opening of the door-shaped frame structure. The device not only solves the problems that a traditional crane crushes farmland and is high in cost, but also can adapt to complex terrains to realize efficient and safe operation, and is particularly suitable for accurate conveying of small-batch materials, and the construction cost is greatly reduced, and the hoisting precision and the field adaptability are improved due to the miniaturized design of taking the tower foundation pile as a fulcrum.

The utility model discloses a kind of quick comminution high oil content solid material crushers, including rack, the rack right lower is sequentially provided with the discharge outlet, the pair of roll crushing assembly, screening assembly and vacuum suction material assembly of intercommunication, the vacuum suction material assembly side is provided with feed inlet, the pair of roll crushing assembly is by several pairs of roll wheel and is distributed in up and down, and the roll wheel at upper end is toothed roll wheel, and the roll wheel at lower end is grooved roll wheel.The utility model uses the mode of vacuum suction material to suck material, so that feeding speed is fast, simultaneously not easy to stick or block in pipeline, simultaneously using filter component has filtered impurity, guaranteed the material quality after comminution, simultaneously, compared with traditional hammer piece type pulverizer and liquid nitrogen freezing pulverizer, crushing silkworm chrysalis and other high oil content material will not be blocked, guarantee production efficiency, and thus the processing speed of comminution can meet the requirement.
