Description

Technical Field

[0001] The utility model belongs to the technical field of long rail vehicle rolling track beams, and in particular relates to a novel long rail vehicle rolling track beam assembly tool. Background Art

[0002] The Shuohuang Railway long rail car has been redesigned. The key component, the roller beam, has undergone significant changes in model and appearance compared to previous long rail cars. Since the original roller beam only had one form, the existing tooling can only assemble one type of roller beam. The existing assembly tooling has a simple structure, and the assembly positioning block is easily displaced, resulting in poor assembly. The roller beam often needs to be adjusted on site, affecting the car body assembly quality and production progress. The roller beams of the Shuohuang Railway long rail car have two forms: rectangular steel roller beams or rotating I-beam roller beams. As a result, the previous assembly tooling is no longer applicable, and the previous marking and assembly method cannot meet the requirements of product quality and production progress. Utility Model Content

[0003] The utility model aims to provide a novel long rail car roller beam assembly tool, which is flexible in application and convenient and accurate in assembly, and solves the problems that the existing tool can only assemble one type of roller beam and cannot be used for two types of rectangular steel roller beams or rotating I-beam roller beams, and the existing assembly tool has a simple structure and the assembly positioning block is easy to shift, resulting in poor assembly.

[0004] To this end, the technical solution adopted by the utility model is: a new type of long rail car roller beam assembly tooling, including a roller beam placement platform and a positioning block, a rotating sleeve positioning boss, and an "L"-shaped limit seat that can be detachably installed on the roller beam placement platform. The roller beam placement platform is centrally and longitudinally spaced with a roller beam placement pad for placing a rectangular steel roller beam or a rotating sleeve I-beam roller beam. The rotating sleeve positioning boss is provided with an arc section that fits with the inner wall of the front end sleeve of the rotating sleeve I-beam roller beam, thereby realizing the positioning of the front end of the rotating sleeve I-beam roller beam. A positioning block is installed directly in front of the rotating sleeve positioning boss, thereby longitudinally limiting the rectangular steel roller beam or the rotating sleeve I-beam roller beam. The remaining positioning blocks are in two asymmetric rows on the left and right, and can be moved to a position corresponding to the roller installation baffles to be installed on the left and right sides of the rectangular steel roller beam or the rotating sleeve I-beam roller beam. The "L"-shaped limit seat is arranged longitudinally, and the vertical end fits the outer side of the positioning blocks in the left and right rows, thereby limiting the longitudinal movement of the positioning blocks.

[0005] As a preferred embodiment of the scheme, the roller beam placement platform includes a placement main board located at the top and a number of supporting columns symmetrically arranged on the left and right sides of the bottom, a horizontal and longitudinal connecting beam is provided between adjacent supporting columns, supporting cross beams are provided around the bottom of the placement main board, and a buffer pad is provided on the contact surface between the top of the supporting column and the supporting cross beam. The design structure is reasonable and the roller beam placement platform structure is stable.

[0006] It is further preferred that the supporting columns, supporting beams and connecting beams are all made of channel steel, which is adapted to local conditions, has simple material procurement and low assembly cost.

[0007] Further preferably, the positioning block is an "L"-shaped plate structure as a whole, and a triangular reinforcing rib plate is provided in the middle, positioning block mounting holes are provided on the left and right sides of the placement main board corresponding to the rectangular steel roller beam or the rotating I-beam roller beam, and mounting through holes corresponding to the positioning block mounting holes are provided on the left and right sides of the positioning block bottom plate. The positioning block is easy to move and is flexibly applicable to the combination and installation of rectangular steel roller beams or rotating I-beam roller beams and roller mounting baffles, and the structural design is reasonable.

[0008] Further preferably, the vertical positioning baffle plate faces backward and fits the installed roller mounting baffle plate, which is reasonably designed and convenient for the installation of the roller mounting baffle plate assembly.

[0009] Beneficial effects of the utility model:

[0010] (1) Compared with the existing tooling that can only assemble one type of roller beam, the design of this solution can detach the positioning block, the rotating sleeve positioning boss, and the "L"-shaped limit seat installed on the roller beam placement platform, so that two types of roller beams, rectangular steel roller beams and rotating sleeve I-beam roller beams, can be placed. The design meets actual needs and the structure is ingenious and flexible.

[0011] (2) Compared with the simple structure of the existing assembly tooling, this solution uses a rotating sleeve positioning boss to position the inner wall of the front end sleeve of the rotating sleeve I-beam roller beam, and a positioning stop in the front limits the longitudinal position of the two roller beams. The two asymmetric rows of positioning stops limit the roller beams on the left and right and also correspond to the roller installation baffles to be installed one by one. The design structure is interlocking, the positioning stop assembly is accurate, and there is no need to adjust the roller beam on site, which significantly improves the body assembly quality and production progress.

[0012] To sum up, it has the advantages of designing in line with actual needs, ingenious and flexible structure, precise positioning gear grouping, and improving vehicle body assembly quality and production progress. BRIEF DESCRIPTION OF THE DRAWINGS
