Description

A sliding spreader for complete replacement of wheels of ladle car reducer in steelmaking system

technical field

The utility model belongs to the technical field of complete replacement and installation of wheels of a ladle car reducer in a steelmaking system for metallurgical machinery, and specifically relates to a sliding spreader for the complete replacement of wheels of a ladle car reducer in a steelmaking system.

Background technique

At present, when replacing the wheels of the ladle car reducer in the frame of the ladle car body in the steelmaking system in industrial production, the replacement of the package does not dismantle the wheels of the ladle car reducer, and at the same time remove the wheels of the ladle car reducer from the ladle car It is extremely difficult to disassemble and install within the body frame, which is a difficult problem in the maintenance process of metallurgical machinery. Now it is generally disassembled and installed manually, and the work efficiency is about 8 hours for 6 people to complete, which is time-consuming and laborious.

Utility model content

The purpose of the utility model is to provide a steelmaking system ladle car reducer wheel complete replacement sliding spreader.

In order to meet the above-mentioned purpose, the technical scheme that the utility model takes is:

A sliding spreader for complete replacement of wheels of a ladle car reducer in a steelmaking system, including a lifting rod, the two ends of the lifting rod are connected with sliding rods through hanging ropes, the sliding rod is located under the lifting rod, and the sliding rod There are a chain block I and a chain block II on it, the chain block I is connected with the reducer on the ladle car, the chain block II is connected with the bearing package on the wheel of the ladle car, the upper part of the lifting rod A suspension ring is provided, the suspension ring is connected with the lifting rod through the suspension rope, and the suspension ring is connected with the lifting device.

Preferably, a sliding sleeve is provided on the sliding rod, and the chain hoist II is fixed on the sliding sleeve of the sliding rod.

Preferably, a groove is provided at the middle part of the sliding rod, and the sliding sleeve can be fixed in the groove at the middle part of the sliding rod.

The beneficial effects of the utility model are: the utility model solves the technical problem that the ladle car cannot be normally hoisted due to the limited space of the ladle car by designing the wheel of the ladle car reducer to replace the sliding spreader. With the cooperation of the chain hoist, the wheels of the ladle car reducer can be disassembled in a small space, and then disassembled by the lifting device, and the wheels of the ladle car reducer can also be installed through this device, saving time and effort.

Description of drawings

Fig. 1 is the structural representation of the utility model;

In the figure: 1. lifting rod, 2. sliding rod, 3. chain hoist I, 4. chain hoist II, 5. reducer, 6. bearing package, 7. lifting ring, 8. sliding sleeve, 9. wheel, 10. Transmission shaft, 11. Ladle car.

Detailed ways

Below in conjunction with accompanying drawing and working principle, the utility model is further described:

As shown in Figure 1, a steelmaking system ladle car reducer wheel complete replacement sliding spreader, including a lifting rod 1, the two ends of the lifting rod 1 are connected with a sliding rod 2 through a hanging rope, and the sliding rod 2 is located on the lifting rod 1 Below, the slide bar 2 is provided with a chain block I3 and a chain block II4, the chain block I3 is connected with the reducer 5 on the ladle car 11, and the chain block II4 is connected with the bearing package 6 on the wheel 9 of the ladle car 11 , the top of the lifting rod 1 is provided with a suspension ring 7, the suspension ring 7 is connected with the lifting rod 1 through a suspension rope, and the suspension ring 7 is connected with the lifting device. There is a sliding sleeve 8 on the sliding rod 2, and the chain hoist II4 is fixed on the sliding sleeve 8 of the sliding rod 2. There is a groove in the middle part of the sliding rod 2, and the sliding sleeve 8 can be fixed in the groove in the middle part of the sliding rod 2. Inside, its function is to be able to move and fix the chain hoist II4 so that it can be connected with the transmission shaft between the reducer 5 and the wheel 9, and the reducer 5 is too heavy to place, and the two ends are not stable when lifting.

When in use, first lift the spreader to the top of the ladle car 11 by the lifting device, then connect the chain block I3 and the chain block II4 on the slide bar 2 to the bearings of the reducer 5 on the ladle car 11 and the wheel 9 respectively. Connect the package 6, then crank the two chain hoists to slightly lift the bearing package 6 of the reducer 5 and the wheel 9, take out the bolts between the ladle car 11 and the bearing package 6 of the wheel 9, and then lower the chain hoist slowly. When the upper wheel edge of the wheel 9 is separated from the ladle car 11 and the lower wheel is along the ground, untie the chain block II4, and move the sliding sleeve 8 on the slide bar 2 and the chain block II4 to the concave hole in the middle of the slide bar 2 at the same time. In the groove, tie the chain hoist II4 to the transmission shaft 10 between the reducer 5 and the wheel 9, and then force the chain hoist I3 and the chain hoist II4 to lift upwards. The tool moves horizontally to the inner side of the ladle car 11, lifts normally after breaking off the car body, and hangs out.
