Description
Technical Field
The invention relates to the technical field of production and manufacturing of steel structures of urban railway vehicle bodies, in particular to a disturbance degree adjusting device for an urban railway vehicle body.
Background
In the production and manufacturing process of the urban railway vehicle body steel structure, the manufactured vehicle body steel structure must meet the requirement of overall deflection of the vehicle body steel structure in a design technical document, namely the manufactured vehicle body steel structure is required to be an overall fan-shaped structure instead of a flat structure, as shown in fig. 7 and 8, the value S4 in fig. 8 is the deflection value of the vehicle body steel structure, and usually the value S4 in the technical condition of the vehicle body steel structure is required to be within a certain numerical range, for example, 10mm is less than or equal to S4 is less than or equal to 20 mm.
In order to meet the technical requirements, when four main components of a vehicle body steel structure, namely, an underframe component, a headwall component, a side wall component and a roof component, are subjected to assembly butt welding production in a general assembly process, a prefabricated support point of vehicle body deflection is required to be arranged in the length direction of a vehicle, and usually, 7 deflection support points are arranged on one side and two sides of the vehicle respectively to ensure that the longitudinal center position of the vehicle body is the highest and the one end and the two ends of the vehicle are the lowest during synthesis of the vehicle body steel structure, and form a gradual and slow descending trend according to a certain descending slope, so that the deflection support is prevented from interfering with circuitous spot welding operations of the side wall component and the underframe component, and therefore, the deflection support points must be arranged on the lower plane of a main beam of the vehicle body underframe component in the transverse direction of the. The arrangement of the main cross beams of the chassis parts among different vehicle types in the same project is different, namely the distance size of the main cross beams of the chassis is changed, so that the vehicle body deflection supporting positions of different vehicle types are different, and when different vehicle types in the same project are alternately produced, the vehicle body deflection supporting positions need to be adjusted according to the vehicle type change.

However, when different vehicle types are produced alternately, the support points with the prefabricated deflection change in the longitudinal direction and the transverse direction of the vehicle, a current vehicle operator needs to manually detach the bolts for fixing the buttresses according to the change, the buttresses are manually moved to new positions and then fixed by the bolts, time and labor are wasted due to the operation mode, the height size of the deflection value needs to be adjusted repeatedly when the support height is adjusted manually, the height of the deflection value is measured repeatedly by a level gauge, and the defects that the adjustment error is large, the support points cannot be locked and fixed after adjustment, the stability of the deflection value is poor and the like exist in the operation mode. The disturbance degree prefabrication process of the steel structure of the car body in the prior art is complicated, poor in precision, time-consuming and labor-consuming, and the requirement for the size precision of the steel structure of the car body in the production process of mass stainless steel urban railway vehicles in the current stage can not be met, and the requirement is urgently needed to be improved.
