AI Technical Summary

Problems solved by technology

Because this is a high-temperature area, steel slag often falls from the vacuum tank, and it is very dangerous for workers to operate here
In addition, it is difficult to ensure the uniform elevation of the top surface of the track of the maintenance trolley and the parallelism of the two tracks due to the placement of a small section of track, resulting in increased resistance. In order to overcome this resistance, the power of the drive motor of the maintenance trolley is often increased. Invisibly increase configuration and maintenance costs

Embodiment Construction

[0015] The invention relates to the field of metallurgy, especially when the ground space of the steel plant is relatively compact, the ladle car and the maintenance trolley in the RH vacuum refining device cannot share the same track to run, and at this time it is necessary to cross the tracks of the ladle car and the maintenance trolley Cross arrangement, in order to ensure that both vehicles can run normally, the invention adopts a new driving structure type of maintenance trolley, which solves the technical problem of difficult operation when the tracks meet.

[0016] see Figure 1 to Figure 4 , the specific structure of a maintenance trolley drive mechanism involved in the present invention is:

[0017] Including driving wheel system 5, driven wheel system 6, driving system 7, universal coupling 8, wheel frame 9, connecting ear seat 10, disc spring 11 and steel pad 12; wherein,

[0018] The wheel frame 9 is hinged under the 4 girders of the main body of the maintenance t...

Abstract

The invention relates to a maintenance trolley driving mechanism which is characterized by comprising driving wheel systems, driven wheel systems, a driving system, universal couplings, wheel carriers, connecting lugs, disc springs and steel cushions. The wheel carriers are hinged below a beam of a maintenance trolley body through the connecting lugs, and the disc springs and the steel cushions are arranged between the wheel carriers and the beam of the maintenance trolley body. Each driving wheel system and each driven wheel system are arranged on one wheel carrier, and the driving system arranged below the beam of the maintenance trolley body is connected with the driving wheel systems through the universal couplings. By the maintenance trolley driving mechanism, the technical problem that it's difficult for a buggy ladle and the maintenance trolley to run on a cross rail in a cross manner is solved, errors caused by manual operations in the prior art are avoided, risks to operators working in high-temperature areas are reduced, resistance to advancing of the buggy ladle and the maintenance trolley is reduced, and allocation and maintenance costs are lowered.

Description

technical field [0001] The invention relates to a driving mechanism of a maintenance trolley. Background technique [0002] Both the ladle car and maintenance trolley are the key equipment for RH vacuum furnace refining. The ladle car is responsible for transporting the ladle to the processing station for vacuum smelting of molten steel, and the maintenance trolley is responsible for scraping slag and gunning maintenance for the two dipping tubes of the vacuum tank involved in molten steel processing. In some steel plants with relatively compact ground space, when the RH vacuum refining device is equipped, the ladle car and the maintenance trolley cannot share the same track. All vehicles can run normally. [0003] At present, the processing method of the cross track is: the ladle car track remains continuous, the rail surface elevation of the maintenance trolley track is a part higher than it, and a section is disconnected when it crosses with it. After the molten steel ...
