Embodiment Construction

[0010] Embodiments of the present invention will now be described in detail in conjunction with the accompanying drawings.

[0011] In order to work stably and reliably, the upper pulley center sheath 2, the shaft 3 and the lower pulley center sheath 6 are all made of high-quality 45# steel, and heat treatment must be carried out after machining. The function of the shaft 3 is to carry the upper pulley The central sheath 2, the function of the upper sheave central sheath 2 is to ensure that the steel wire rope 7 is always in the center position, the function of the bolt rod 5 is to carry the lower sheave central sheath 6, and the function of the lower sheave central sheath 6 is to ensure that the steel wire rope 7 Always in the central position, the left guard plate 1 and the right guard plate 4 are made of stainless steel.

[0012] In summary, the present invention is convenient and stable to use, safe and reliable.

Abstract

The invention belongs to a pulley-type hoisting connecting piece which is used in the hoisting industry, aiming at overcoming the defect that a D-type fastener is used in the hoisting industry at present, the position of a steel wire rope is not fixed in the D-type fastener, and the steel wire rope has very small bending radius and centralized stress, so that safety accident is easily caused in the hoisting operation. The pulley-type hoisting connecting piece is characterized in that a left and a right guard boards are provided with a shaft and a bolt rod; the shaft is provided with an upper pulley central jacket, and the bolt rod is provided with a lower pulley central jacket; and the steel wire rope is arranged on the upper and the lower pulley central jackets. The pulley-type hoisting connecting piece increases the bending radius, reduces the stress for the steel wire rope and ensures the hoisting operation to be safe.

Description

Technical field: [0001] The invention belongs to a pulley-type hoisting connector box used in the hoisting industry. Background technique: [0002] The D-type buckle used in the current hoisting operation generally exists because the position of the steel wire rope in the D-type buckle is not fixed, and the bending radius of the steel wire rope is very small and the stress is concentrated, so safety accidents are easy to occur during the hoisting operation. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a pulley-type hoisting connector. [0004] The present invention is achieved in this way: a pulley-type hoisting connector is composed of a left guard plate, an upper pulley center sheath, a shaft, a right guard plate, a bolt rod, a lower pulley center sheath and a steel wire rope, and is characterized in that : There are shafts and bolt rods installed on the left and right guard plates, the uppe...
