Description

Ladle Tilting Machine Transmission

Technical field:

The utility model relates to a transmission device of a ladle tipping machine, which belongs to the technical field of metallurgical equipment.

Background technique:

In the field of iron and steel smelting production, during the use of the ladle, operations such as online replacement of the sliding nozzle and hot repair must be performed, and the ladle must be tipped before these operations are performed. At present, general iron and steel enterprises use the crown crane on the production site and the ground production workers to work together to complete the tipping action of the ladle, which affects the operation rate of the production crane and reduces production efficiency. Someone designed and produced a ladle tipping device. After being applied in actual production, it has a very significant effect on improving the production rate. However, the transmission mode is still backward. The traditional deceleration transmission mode needs to occupy a large amount of time to achieve large torque and high speed ratio transmission. In the production site, in the steelmaking production operations of iron and steel enterprises, many reasons why there are no supporting special ladle tilting devices are that the space of the on-site operation area is small, so that the practical application of the ladle tilting device technology is greatly restricted.

Utility model content:

The purpose of the utility model is to provide a transmission device for a ladle tipping machine, which does not require cranes and workers to assist in operations, is easy to use, occupies a small space, has a large torque and a large speed ratio, ensures safe production, and solves the above-mentioned problems in the background technology.

The technical scheme of the utility model is: a transmission device of a ladle tipping machine includes a motor, a reducer, a coupling, a gear shaft, a secondary reduction mechanism, a supporting main shaft, and a locking and turning frame. The output shaft of the motor and the reducer are the same Arranged in parallel, the reducer is connected to the secondary reduction mechanism through the coupling and the gear shaft, and the secondary reduction mechanism is connected to the locking flip frame suspended on the supporting main shaft.

The secondary reduction mechanism is an open-type pin-tooth transmission mechanism, which is composed of a gear and a pin-toothed disc. The pin-toothed disc is connected with a locking and turning frame suspended on the supporting main shaft through a connecting shaft.

The utility model finally transmits the torque to the locking tipping frame through the two deceleration mechanisms, and the tipping frame realizes the tipping action of the ladle.

The said reducer is a three-ring reducer, and the motor and the output shaft of the reducer are arranged in parallel in the same direction, which saves space. The transmission with large speed ratio optimizes the connection between the deceleration transmission chain and the locking and turning frame that accepts the fixed ladle, thus meeting the design requirements of the process operation of the ladle tipping device.

The entire transmission mechanism is fixed on the transmission base, and the transmission base is directly fixed on the ground of the site. The equipment works reliably and has good safety.

The beneficial effects of the utility model are: the design of the transmission mode not only saves the floor space obviously compared with the traditional deceleration mode, but also realizes a transmission with large torque and high speed ratio, thereby meeting the process design requirements of the ladle tipping device, and more It solves the practical problem that iron and steel enterprises cannot use the ladle tipping device due to the tight working space on site. After using this transmission mode of the ladle tipping device, the crane only needs to lift the ladle to the tipping device and no longer participates in The ladle tipping operation significantly improves the steelmaking production operation rate.
