Abstract
The utility model discloses a motor suspension bracket reinforcing plate. In the current troubleshooting work, the troubleshooting department performs flaw detection and welding on a motor suspension bracket according to a normal troubleshooting flow, and can not ensure the motor suspension bracket not to generate a crack fault before next troubleshooting. The utility model aims to designing a firmer and more reliable motor suspension bracket reinforcing scheme, in order to thoroughly eliminate the potential safety hazard of fatigue crack easily generated in the operation process of the motor suspension bracket. The technical scheme is implemented through the steps of: designing a subtriangular motor suspension bracket reinforcing plate, arranging the subtriangular motor suspension bracket reinforcing plate in a motor suspension bracket fixedly connected with a framework end portion through welding, enabling the upper edge of the reinforcing plate to fit with the bottom surface of the top plate of the motor suspension bracket, enabling the vertical edge of the reinforcing plate to fit with the framework end portion, and fixedly connecting the reinforcing plate and the motor suspension bracket with the framework end portion through welding. According to the technical scheme, the motor suspension bracket reinforcing plate is simple in operation method, low in material consumption and manpower consumption, and good in obtained reinforcing effect, thereby eliminating the potential safety hazard in the operation process of a passenger car, and providing guarantee for the normal use of a power generation main-vehicle.
Description
Technical field
The utility model relates to a kind of maintenance program of railway passenger car bogie motor suspension bracket, specifically relates to a kind of motor suspension bracket stiffening plate.
Background technology
Passenger vehicle 206G bogie by overhaul rules and service technique condition, needs the motor suspension bracket is partly done electromagnetic test and the defective of being found is carried out repair welding when carrying out repair in shop.The suspension bracket part is born generator and the gravity of adjusting device and the alternate stress that in vibrations, produces thereof under the car when utilization; Because passenger vehicle constantly speed-raising brings running down of service conditions, thereby cause after the fatigue, material corrosion of metal material itself that problem such as intensity reduction finally causes suspension bracket mother metal generation rhegma fault.At 2009-2010; The fault of motor suspension bracket mother metal rhegma successively appears in part road bureau; Continue operation like the fault bogie and the suspension bracket fracture then possibly occur, accessory falls into track and causes vehicle derailing, so the fault vehicle can not be participated in operation once finding then to do to roll off the production line to overhaul.Because of the passenger vehicle marshalling needs, the female car of generating that has the motor suspension bracket is 1:1 with receiving electronics car marshalling ratio, and the fault vehicle can not be participated in operation and bring bigger use difficulty to the user, at operational vehicle the safe operation of passenger vehicle is also brought bigger potential safety hazard.
In the existing upkeep operation, 206G type bogie motor suspension bracket does not have the unified reinforcement scheme of the Ministry of Railways, and majority maintenance unit only suspension bracket is detected a flaw by normal maintenance flow process and repair welding is handled.
If utilize prior art to carry out upkeep operation, can't guarantee before carrying out repair in shop next time, can not produce the rhegma fault through the 206G type bogie motor suspension bracket of utilization in 10 ~ 20 years.
Summary of the invention
The purpose of the utility model is, designs a kind of more firm, passenger car bogie motor suspension bracket reinforcement scheme reliably, thoroughly eliminates the motor suspension bracket and is in operation and is easy to generate the potential safety hazard of fatigue crack.
The purpose of the utility model realizes through adopting following technical scheme:
At first design a kind of motor suspension bracket stiffening plate; It is characterized in that: said motor suspension bracket stiffening plate is a subtriangular steel plate; Place in the motor suspension bracket that is connected with the welding of framework end; Originally the motor suspension bracket that was box-structure is divided into two parts in length direction, and its top edge and motor suspension bracket top board bottom surface match its stile and framework end anastomosis.
Utilize the welding of above-mentioned a kind of motor suspension bracket stiffening plate and motor suspension bracket and framework end to be connected and found a kind of motor suspension bracket reinforcement scheme, may further comprise the steps:
A. when welding, cause the distortion of motor suspension bracket for preventing, penetrate the technology pin in the motor hole for hoist on said motor suspension bracket;
B. the junction of said motor suspension bracket stiffening plate and motor suspension bracket and framework end is welded;
C. the motor suspension bracket integral body of welding motor suspension bracket stiffening plate is incubated processing;
D. after treating the said motor suspension bracket natural cooling that has welded motor suspension bracket stiffening plate, remove technology pin described in the steps A, and it is carried out scribing inspection, confirm fitted position.
This programme method of operation is simple, and the material and the manual work that are consumed are lower, and the reinforcing effect of obtaining is better, and through the runtime verification of road bureau's vehicle, the rhegma fault did not appear in 2 years in the operation of the improved homotype motor of reinforcement suspension bracket.The potential safety hazard of having eliminated the passenger vehicle operation also provides guarantee for the normal use of the female car of generating.
Description of drawings
Fig. 1 is a motor suspension bracket fatigue crack sketch map in the utility model;
Fig. 2 is that motor suspension bracket stiffening plate combines sketch map with the motor suspension bracket in the utility model.
Reference numeral: 1-motor suspension bracket, 2-motor suspension bracket stiffening plate, 3-motor hole for hoist, 4-framework.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 1, shown in Figure 2; At first design a kind of motor suspension bracket stiffening plate; It is characterized in that: said motor suspension bracket stiffening plate 2 is a subtriangular steel plate, places in the motor suspension bracket 1 that is connected with framework 4 ends welding, and the motor suspension bracket 1 that was box-structure originally is divided into two parts in length direction; Its top edge and motor suspension bracket 1 top board bottom surface match, its stile and framework 4 end anastomosis; The thickness of said motor suspension bracket stiffening plate 2 is preferably 16mm.
Utilize the welding of above-mentioned a kind of motor suspension bracket stiffening plate 2 and motor suspension bracket 1 and framework 4 ends to be connected and found a kind of motor suspension bracket reinforcement scheme, may further comprise the steps:
A. when welding, cause 1 distortion of motor suspension bracket for preventing, penetrate the technology pin in the motor hole for hoist 4 on said motor suspension bracket 1;
B. the said motor suspension bracket stiffening plate 2 and the junction of motor suspension bracket 1 and framework 4 ends are welded;
C. motor suspension bracket 1 integral body of welding motor suspension bracket stiffening plate 2 is incubated processing;
D. after treating said motor suspension bracket 1 natural cooling that has welded motor suspension bracket stiffening plate 2, remove technology pin described in the steps A, and it is carried out scribing inspection, confirm fitted position.
