Problems solved by technology

2. During the actual operation, the workers also found that because the pressure of the press machine is generally high, the bending of the cross bar often occurs and the adjustment is not qualified. Instead, the cross bar is flattened and becomes a scrap product. In the end, the gain outweighs the loss
3. Since the working platform and hydraulic telescopic part of the press cannot translate in translation, the bending position on the positioning cross bar is more complicated
These three disadvantages are the fatal problem of press adjustment and bending cross bar, which seriously affects the adjustable quality and quantity of cross bar, and the effect of saving cross bar maintenance cost is less than 50% of the cost saving.
It can be said that these three shortcomings are also the reasons why this repair method has not been widely promoted.

Abstract

The invention relates to a device for adjusting bending of a cross rod for a rail wagon; currently, a pressure machine is used for adjusting the bent cross rod so that the adjusting quality and quantity of the cross rod is seriously influenced; the action for saving cost for adjusting the cross rod does not reach 50% for saving cost. The product comprises a base frame (1); a cross rod installation seat (2) is connected at the two ends of the bottom frame; a group of smooth beams (3) is connected at the two sides of the bottom frame; a rail installation seat (4) is installed on each group of smooth beams; a sliding guide rail (5) is installed on the rail installation seat; the sliding guide rail is connected with an end part adjusting device (6) through a guide rail sliding block (14); and the sliding guide rail in one group is connected with a middle adjusting device (7) through a guide rail sliding block (15). The product is used for adjusting bending of the cross rod for the rail wagon.

Description

Technical field: [0001] The invention relates to a bending adjustment and repairing device for a cross bar of a railway freight car. Background technique: [0002] The cross bar is an important part of the cross bracing device installed on the railway freight car bogie. The cross bracing device is a device installed between the two side frames on the basis of the three bogies. The shear deformation of the frame is constrained elastically, and the rhomboid deformation is suppressed, so that the bogie has a certain ability to restore the normal position. Since the cross support device has to exert elastic constraints on the bogie, it is often found that the cross rods are bent and deformed during the operation of the vehicle. According to the production of 400 vehicles / month of our company, a total of 800 cross rods are inspected per month. Among them, the cross bars within the adjustable repair range account for 8% of the cross bar inspections in the current month, then the ...
