Description

Technical Field

[0001] The invention belongs to the technical field of molten iron transportation equipment, and in particular relates to a vehicle-mounted covering device for master and slave ends of a mixed iron vehicle. Background Art

[0002] The mixing car is an important tool for transporting molten iron in the modern metallurgical industry. During the transportation of molten iron, the smoke from the molten iron in the tank of the mixing car will cause serious pollution to the atmospheric environment on the one hand, and on the other hand, it will cause the overall temperature of the molten iron to drop, increase energy loss, and affect the subsequent steelmaking process. Based on this, major steel mills have added capping equipment to the original mixing car. The setting of the capping equipment has effectively solved the problem of excessive dissipation of molten iron heat through the tank mouth and the increase of environmental pollution caused by the smoke.

[0003] The molten iron transported by the iron-mixing car is an ultra-high temperature liquid. To avoid major safety accidents, the iron-mixing car usually needs to be taken offline for maintenance after two months of operation. Generally speaking, after the existing capping equipment is installed on the iron-mixing car, it does not need to be moved. Therefore, during the maintenance of the iron-mixing car, the capping equipment on the iron-mixing car will remain idle, and the utilization rate of each capping equipment is low, resulting in a waste of equipment resources.

[0004] In addition, the existing mixed-iron cars are all towed by locomotives, and a driving mechanism for rotating and dumping the mixed-iron car torpedo tanks is installed at the driving end close to the locomotive. The available space is relatively small compared to the driven end. The existing mixed-iron car capping equipment has a complex structure and occupies a large space. Therefore, the existing capping equipment is installed at the driven end of the mixed-iron car. Figure 1 The schematic diagram of the existing hybrid car is shown, with the two sides of the hybrid car 6 being the active end 61 and the driven end 62, the middle being the tank body, and one side being provided with an electric control box and a hydraulic station 63 for controlling the tank body operation. In the future, most hybrid cars will be developed in the direction of self-driving, and the driven end of the hybrid car will also need to be equipped with a power system and a transmission system for driving the travel, and the available space will become narrower. The existing capping equipment is difficult to be installed on the driven end of the hybrid car, so it is particularly urgent to design a capping equipment that is more convenient to be installed on the active and driven ends of the hybrid car. Summary of the invention

[0005] The present invention provides a vehicle-mounted covering device for the master and slave ends of a hybrid railcar. The parts other than a bracket assembly can be integrated into an integrally movable vehicle-mounted covering device unit, which can be quickly disassembled and assembled at the master and slave ends of various hybrid railcars, effectively solving the problem of low utilization rate of existing covering equipment. In addition, through the designed simple structure, it can be quickly installed when the space at the master and slave ends of the hybrid railcar is limited.

[0026] (3) The vehicle-mounted covering device for the driving and driven ends of the hybrid vehicle of the present invention can be equipped with a bracket assembly adapted to the driving end or driven end of the hybrid vehicle, and can select the rows of first adjusting bolt holes on the base adjustment frame corresponding to the rows of second adjusting bolt holes on the base frame for bolt connection according to installation requirements, so as to facilitate installation and adjustment at the driving end or driven end with limited space. The bracket assembly occupies a small space, and cooperates with the vehicle-mounted covering device unit with a simple structure, so that the activity space required for completing the corresponding covering action is also narrower, which is convenient for installation and use.

[0027] (4) In the guide rollers of the vehicle-mounted covering device for the master and slave ends of the hybrid iron vehicle described in the present invention, an oil-containing bearing is provided, and a sealing ring is installed on the outside of the oil-containing bearing. When the equipment is running, dust in the air and smoke and dust emitted by molten iron are prevented from entering, thereby preventing the service life of the guide rollers from being shortened, and the entire guide device can be maintenance-free for life.
