Description

Technical Field

[0001] The invention relates to the technical field of equipment maintenance, and in particular to a disassembly and assembly method for a brake cylinder of a Smart hybrid vehicle. Background Art

[0002] The iron mixer car is a large-scale molten iron transportation equipment with the advantages of small heat loss, long insulation time, and energy saving. It can also store molten iron to coordinate the temporary imbalance between ironmaking and steelmaking. At the same time, it can replace the steelmaking iron mixer and ordinary molten iron tank car, and can also complete desulfurization, dephosphorization and other operations during the molten iron transportation process.

[0003] Traditional hybrid cars have no power device and need to be towed by a locomotive. Smart hybrid cars are modified on the basis of traditional hybrid cars. They mainly add power devices, transmission devices, brake devices and cooling devices to the driven end of traditional hybrid cars to realize automatic driving of hybrid cars without the need for locomotive towing.

[0004] In order to realize the braking function of the Smart hybrid car, an air pump, air reservoir, control device, brake cylinder and corresponding connecting pipes are added to the driven end. There are six sets of brake cylinders, which are located at the front, middle and rear positions of the driven end.

[0005] The brake cylinder is an important component to achieve the braking performance of the hybrid car. Through its air intake and exhaust, it controls the contact and separation between the brake shoe and the wheel to achieve the braking and release of the hybrid car. Because the brake cylinder is frequently used, failures often occur, so it needs to be disassembled and replaced. The brake cylinder weighs about 70kg, and the left and right sides and the rear are fitted with the bracket. The brake cylinder is connected to the bracket by three bolts, and the bracket is directly welded to the car body, and the positioning accuracy is required to be high.

[0006] When disassembling and assembling the brake cylinder, there is no suitable lifting point and it cannot be lifted into place by a crane. The only way to disassemble and replace it is to use a jack and a crane. If the occasion where the brake cylinder needs to be disassembled and replaced occurs on site, it can only be done by manpower. This greatly increases the difficulty of disassembling and assembling the brake cylinder, increases the labor intensity of the disassembly and assembly operation, reduces the efficiency of the disassembly and assembly operation, and there are certain safety hazards in the disassembly and assembly process, making it difficult to ensure the disassembly and assembly quality of the brake cylinder.
