Abstract
The invention relates to a rail wagon wall body plug-in type structure. The rail wagon wall body plug-in type structure comprises a column body and a wall board and is characterized in the lower portion of the column body is symmetrically provided with two plug-in grooves opposite in opening direction, wherein the plug-in ends of the wall board are provided with lower convex edges matched with the sunken portions of the bottoms of the plug-in grooves and plugged into the plug-in grooves of the column body to be in tight match with the plug-in grooves. The rail wagon wall body plug-in type structure has the advantages that the structure is simple and reliable, vehicle maintenance is facilitated, the column body and the wall board are matched tightly, especially plugged steel wires enable assembling gaps formed by the column body and the wall board to be eliminated and enable the matching of the column body and the wall board to be tight, and the structure can meet the heavy-load freight requirement and used for manufacturing 80t-load-class rail wagons and 100t-load-class rail wagons.
Description
Technical field
The present invention relates to a kind of Rail wagon wall body plug-in type structure, belong to field of mechanical technique.
Background technology
Lorry body is as the main element in railway freight-car bearing structure, and it is primarily subjected to come from multiple directions active force.At present, domestic lorry body is mainly made up of wall, underframe etc., so as to constitute the primary load bearing structure of rolling stock, meets traction requirement, the handling goods job requirements of ten-thousand ton trains marshalling.Wherein, the wall of car body is usually plate column type structure, and connected mode is generally divided into two kinds of traditional welding structure and riveted structure, is mainly integrated cylinder and wallboard by the method for welding or staking.Welded welding deformation is whard to control, construction environment is poor, and the assembling procedure of riveted structure is cumbersome, manufacturing time length, low production efficiency.
The content of the invention
The deficiency existed for above-mentioned wall connecting mode, it is an object of the invention to provide a kind of Rail wagon wall body plug-in type structure, under equal strength and rigidity, meet car body and use and assemble requirement, realize and simplify manufacture link, lift operating efficiency, shorten the manufacturing cycle, facilitate car inspection and repair.
To achieve the above object, the present invention uses following scheme：
A kind of Rail wagon wall body plug-in type structure, including cylinder, wallboard, it is characterized in that：In the inserting groove opposite provided with two opening directions of the bottom of cylinder symmetrically, the opening direction of two inserting grooves is respectively towards two outsides of cylinder, the top of inserting groove is horizontal flap, inserting groove is the horizontal sides parallel with horizontal flap below, downward depression is arranged at the bottom of inserting groove, the lower fin being coincide with inserting groove bottom notch is provided with the inserted terminal of wallboard, the inserted terminal of wallboard is plugged in the inserting groove of cylinder, is fitted close with inserting groove.
Level is provided with the axis semi arch locking slot vertical with the cross section of cylinder on the inwall of the bottom of the inserting groove, semi arch locking slot is provided with side of the inserted terminal along wallboard of wallboard, after the inserted terminal of wallboard coordinates with inserting groove, the semi arch locking slot of grafting trench bottom synthesizes a pipe with the semi arch locking slot of wallboard side, and the steel wire being interference fitted with pipe is inserted with pipe.
The cross section to lower recess of the grafting trench bottom is trapezoidal.
It is an advantage of the invention that：It is simple in construction, reliable, facilitate car inspection and repair, coordinate close between cylinder and wallboard, the particularly insertion of steel wire is by cylinder and the assembly clearance asphyxia by external pressure on the chest and abdomen of wallboard, so that their cooperation is even closer, Heavy-haul Freight requirement is suitable for, for manufacturing 80t grades of load-carrying and 100t grades of railway freight-cars of load-carrying.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the cross-sectional view of cylinder；
Fig. 3 is the cross-sectional view of wallboard.
In figure：1st, wallboard；2nd, cylinder；3rd, steel wire；4th, inserting groove；11st, lower fin；12nd, the semi arch locking slot of wallboard side；41st, horizontal flap；42nd, inserting groove is following；43rd, the semi arch locking slot of grafting trench bottom.
Embodiment
Referring to the drawings, the present invention includes cylinder 2, wallboard 1, in the inserting groove 4 opposite provided with two opening directions of the bottom of cylinder symmetrically, the opening direction of two inserting grooves is respectively towards two outsides of cylinder, the top of inserting groove is horizontal flap 41, following the 42 of inserting groove are the horizontal sides parallel with horizontal flap, downward depression is arranged at the bottom of inserting groove, level is provided with the axis semi arch locking slot 43 vertical with the cross section of cylinder on the inwall of the bottom of inserting groove, the lower fin 11 being coincide with inserting groove bottom notch is provided with the inserted terminal of wallboard, semi arch locking slot 12 is provided with side of the inserted terminal along wallboard of wallboard, the inserted terminal of wallboard is plugged in the inserting groove of cylinder, it is fitted close with inserting groove, the semi arch locking slot of grafting trench bottom synthesizes a pipe with the semi arch locking slot of wallboard side, the steel wire 3 being interference fitted with pipe is inserted with pipe.The present invention mounting means be：First wallboard is inserted in the inserting groove of cylinder, then is inserted into steel wire in the pipe of cylinder and wallboard junction.
Claims (3)
1. a kind of Rail wagon wall body plug-in type structure, including cylinder, wallboard, it is characterized in that：In the inserting groove opposite provided with two opening directions of the bottom of cylinder symmetrically, the opening direction of two inserting grooves is respectively towards two outsides of cylinder, the top of inserting groove is horizontal flap, inserting groove is the horizontal sides parallel with horizontal flap below, downward depression is arranged at the bottom of inserting groove, the lower fin being coincide with inserting groove bottom notch is provided with the inserted terminal of wallboard, the inserted terminal of wallboard is plugged in the inserting groove of cylinder, is fitted close with inserting groove.
