Problems solved by technology

For this reason, the feasible solution is to measure the deflection value of each car and then select the thickness of the block, and add the block with the same thickness to ensure that the height meets the requirements. The disadvantage is that it is troublesome and the auxiliary working time is long.
In addition, because the installation position of the accessories is in the narrow space surrounded by the middle beam, cross beam and side beam of the tooling, the tooling with the positioning surface of the column is formed on the conventional platform, and the column of the tooling invades the operating space of the worker, and the operator has almost no work space. The working space is more embarrassing

Abstract

The invention discloses a modular assembly and use method for attachments of flat car underframes, which solves the problem of limited installation space for the attachments of flat car underframes in the prior art, and has the beneficial effect of improving the installation efficiency of the attachments. The specific plan is as follows: a modular assembly tooling for the accessories of the flat car chassis, including a fixed lower platform, which is set on the ground or fixed on the frame; the upper and lower platform can be lifted and lowered, and the upper and lower platform can be lifted relative to the fixed lower platform. The lifting upper platform includes the tooling main beam, which fixes multiple tooling beams, and there is a set distance between two adjacent tooling beams to facilitate people's entry or exit. The lifting upper platform is set for multiple positioning of accessories Seats; supporting seats are arranged on both sides of the fixed lower platform, and the supporting seats on both sides are respectively used to support the two sides of the lower surface of the workpiece.

Description

technical field [0001] The invention relates to the field of railway wagons, in particular to a modular assembly and use method for the accessory parts of a flat wagon underframe. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] There are many accessories for the bottom frame of flat car, including 120 valve hanger, auxiliary air cylinder hanger, 11 liter air cylinder hanger, 28 liter air cylinder hanger, pipe hanger G214, proportional valve hanger, brake cylinder hanger Seats, hangers, etc., such as figure 1 and figure 2 As shown, each accessory part is welded on the web plate of the middle beam, cross beam and side beam of the flat car tooling. [0004] The accessories are distributed centrally based on the 120 valve suspension seat to form an integral module. The positioning datum in the height direction is the upper plane of the mi...
