AI Technical Summary
The existing main hoisting pulley block of metallurgical cranes suffers severe wear after long-term use, has poor installation stability, and is inconvenient for lubricating the hoisting wire rope.
A main hoisting pulley block for a metallurgical crane was designed, comprising components such as a pulley support frame, a cavity seat, an adjusting plate, a fixed pulley, and an oil tank. Stable installation is achieved through structures such as T-shaped positioning blocks, limit springs, and L-shaped baffles, and convenient addition of lubricating oil and prevention of contamination are achieved through the oil tank and oil-absorbing sponge.
It improves the installation stability and lubrication effect of the fixed pulley block, facilitates the disassembly and maintenance of the fixed pulley block and the lubrication of the lifting wire rope, avoids lubricating oil contamination, and enhances the practicality of the equipment.

Abstract
Claims
1. A main hoisting sheave block of a metallurgical crane, comprising a sheave support frame, a cavity seat and an adjusting plate, characterized in that: The pulley support frame has a fixed pulley rotatably connected to its interior via a shaft. A lifting wire rope is connected to the outer surface of the fixed pulley. A T-shaped positioning block is installed on the top of the pulley support frame. The cavity seat has T-shaped positioning grooves and T-shaped sliding grooves. A limit spring is installed inside the T-shaped sliding groove, with a T-shaped slider at one end and an L-shaped baffle at the other. An L-shaped fixing plate is installed on the top of the cavity seat, with a first threaded hole inside and a first bolt inside. Second threaded holes are opened on both sides of the cavity seat, with second bolts inside. A locking block is installed on one side of the adjusting plate. An oil reservoir is installed on the inner wall of the pulley support frame, containing an oil-absorbing sponge. An L-shaped rod is rotatably connected to one side of the oil reservoir via a shaft, with a circular baffle at one end and a return spring at the other. A mating block is installed on one side of the oil reservoir, and an oil filling hole is also located on one side of the oil reservoir.
2. A metallurgical crane main hoisting sheave block according to claim 1, characterized in that: The end of the T-shaped positioning block is inserted into the inside of the T-shaped positioning groove, and the end of the T-shaped slider is located inside the T-shaped sliding groove.
3. A metallurgical crane main hoisting sheave block according to claim 1, characterized in that: One side of the T-shaped positioning block has a slot with the left and right directions as the depth direction, and the end of the block away from the adjustment plate is inserted into the slot.
4. A metallurgical crane main hoisting sheave block according to claim 1, characterized in that: The L-shaped baffles abut against the first bolt and the second bolt respectively, and the adjusting plate abuts against the cavity seat.
5. A metallurgical crane main hoisting sheave block according to claim 1, characterized in that: The lifting wire rope runs through the oil storage tank, the oil-absorbing sponge is in contact with the lifting wire rope, and there are several fixed pulleys.
6. A metallurgical crane main hoisting sheave block according to claim 1, characterized in that: The position of the oil filling hole corresponds to the position of the circular baffle. The circular baffle abuts against the oil reservoir. The end of the return spring away from the L-shaped rod is fixedly connected to the mating block.
