3results about How to "Avoid wear failure" patented technology

This invention relates to a disassembly tool for the output end of a hydraulic coupler, comprising a puller, a ball-head push rod, a release sleeve, and an adjusting disc. The puller includes a hydraulic push rod and pull claws. The release sleeve has a central hole with a T-shaped cross-section, a convex ring at the top, and threads on its lower outer wall. The adjusting disc is a circular disc with threads on its inner wall. The inner diameter of the circular disc matches the lower outer diameter of the release sleeve and is smaller than the outer diameter of the top ring of the release sleeve. The ball-head push rod is installed in the central hole of the release sleeve, and its outer diameter is not greater than the inner diameter of the hole. This invention utilizes the engagement between the threads on the outer wall of the release sleeve and the release threads on the inner wall of the deep hole at the output end of the coupler. The force is transmitted through the ball-head push rod to the shaft end of the driven equipment, separating the coupler from the shaft end. The ball-head push rod effectively protects the shaft end of the driven equipment from damage and prevents wear and failure of the release threads.

This utility model discloses a corrosion-resistant prestressed concrete pipe pile for soft soil foundations, relating to the field of pile foundation technology. The corrosion-resistant prestressed concrete pipe pile for soft soil foundations includes a pile body, a pile tip, a pile cap, and prestressing tendons. The pile body includes a buffer layer, an anti-corrosion layer, and a steel pipe layer distributed radially from the outside to the inside. A pouring cavity for concrete is formed within the steel pipe layer, and a reinforcing cage is installed within the pouring cavity. The pile tip has a pointed end and a connecting end at opposite ends, connected to the bottom of the steel pipe layer via a connecting plate. The pile cap is connected to the top of the steel pipe layer, and a grouting hole communicating with the pouring cavity is opened on the pile cap. The prestressing tendons are inserted within the reinforcing cage, extending axially along the pile body, and are connected between the pile cap and the connecting plate. The concrete, reinforcing cage, and prestressing tendons form an integrated load-bearing structure, improving the structural strength of the pile body. The buffer layer prevents the anti-corrosion layer from wearing away during pile driving, extending the service life of the pipe pile.

The utility model provides an anti -wear expansion joint, including import pipe subassembly, ring plate subassembly, flow guide tube, export pipe subassembly and bellows, ring plate subassembly and flow guide tube have the accommodation space between, the dustproof ring, first baffle ring and second baffle ring are provided in the accommodation space, one end of first baffle ring and ring plate subassembly are connected, the other end extends to flow guide tube and has the gap between flow guide tube, one end of second baffle ring and flow guide tube are connected, the other end extends to ring plate subassembly and has the gap between ring plate subassembly, first baffle ring and second baffle ring set up in the downstream side of dustproof ring. Utilize dustproof ring to seal and play the first barrier action to the accommodation space formed between two. First baffle ring and second baffle ring further play the second barrier action, prevent the tiny solid particle with the flow of medium to pass through dustproof ring and reach bellows and cause the wear failure of bellows, guarantee the safe and reliable operation of expansion joint.
