Description
Technical Field
The utility model relates to a wire rope electric block reel.
Background
The crane wire rope electric hoist winding drum is an important accessory of a crane and a related electric hoist; the drum is a part of a hoisting mechanism for winding a wire rope. The winding drum is composed of a winding drum, a winding drum shaft, a flange, a winding drum hub, a bearing seat and the like, and is used as a whole.
The winding drum is a long thin-walled drum, and the outer side wall surface of the winding drum is provided with continuous and close spiral grooves for clamping the steel wire rope to wind and store the steel wire rope. Besides the function of storing the steel cable, the drum needs to provide a steel cable fixing device at the end. The conventional steel wire rope is fixed by a wedge-shaped block and a pressing plate, wherein the pressing plate is widely used.
When the pressing plate is adopted for pressing, a mounting hole is generally processed in the spiral groove, and then the steel wire rope is pressed through a bolt, a nut and a pressing block; however, the winding drum needs frequent starting, stopping and rotation during use, so that the bolt and the nut which are in threaded connection are matched, loosening is easy to occur, once the loosening occurs, the steel wire rope is easy to fall off, and the hoisting safety is damaged. In order to improve the reliability of threaded connection, a locknut with nylon is often used or threaded glue is adopted; however, the nylon locknut can be used only once, and once the nylon locknut is disassembled, the nylon locknut needs to be scrapped and replaced by a new one, so that the maintenance cost is increased; the threaded glue increases the disassembly difficulty, and the bolt head is generally hidden inside the winding drum, so that the tool is not easy to operate.
In order to improve the installation of the pressing plate and increase the fixing safety of the steel wire rope, some new technical schemes are proposed in the field, for example, a new winding drum with chinese patent publication No. CN203699768U processes a fixing groove on an original spiral groove, and fixes the steel wire rope in the form of the fixing groove, but the steel wire rope easily rubs the fixing groove, resulting in the abrasion of the steel wire rope head and the abrasion of the fixing groove, on one hand, the damage of the steel wire rope is accelerated, and on the other hand, once the fixing groove is abraded, the fixing failure is caused.
Although the reel is a mature product, the structure of the reel still needs to be further improved, and the safety and reliability of the reel are improved.
