Abstract
The invention relates to railway transportation equipment and particularly relates to a strut device for a railway gondola. The strut device comprises a horizontal strut and horizontal strut seats, wherein the horizontal strut seats are mounted on a sidewall of the freight train and support the horizontal strut. The key technical point is as follows: the horizontal strut and the horizontal strut seats are connected through connecting shafts, a cushioning rubber pad and a stop block are sequentially sleeved on each of the two ends of each connecting shaft, the two ends of each connecting shaft are respectively connected with the horizontal strut and lock nuts, and triangular trusses are mounted below the horizontal strut seats. The strut device has the beneficial effects that the horizontal strut and the horizontal strut seats are connected by adopting the cushioning rubber pads, and the cushioning rubber pads are rubber elements and have high axial rigidity and low rotational rigidity, so that the problem in the existing railway freight trains that the horizontal strut and the horizontal strut seats are of rigid connection is solved effectively, the flexible connection between the horizontal strut seats and the horizontal strut is realized, the stress status of the horizontal strut is improved, and the probability of horizontal strut fracture is lowered.
Description
Technical field
The present invention relates to equipment of railway transportation, particularly truck brace apparatus.
Background technology
Truck is in operational process, and due to the lateral pressure effect of goods, side wall is certain outer swollen by occurring, and is to guarantee traffic safety, and general employing set up outer swollen the moving that pole structure is controlled side wall at present, between strut and strut socket, adopts and is articulated and connected.The brace apparatus of this structure, when swollen outside side wall, because the joint gap at the place that is articulated and connected is too small, caused junction to offer the rotational stiffness of strut too small, therefore often there is the situation of strut socket place bolt looseness and strut fracture in brace apparatus, this has not only improved the maintenance cost of brace apparatus, has also reduced the safety of vehicle operating simultaneously.
Summary of the invention
The problem to be solved in the present invention is exactly that a kind of special-purpose brace apparatus of railway truck that can solve easily strut socket place bolt looseness and strut breakage problem is provided for the deficiencies in the prior art.Its technical scheme is as follows:
It comprises triatic stay and horizontal brace pole socket, and horizontal brace pole socket is arranged on the side wall of lorry, and triatic stay is supported on horizontal brace pole socket.Its gordian technique is that triatic stay is connected by adapter shaft with horizontal brace pole socket, and adapter shaft two ends are set with respectively buffer rubber gasket and link stopper successively, and adapter shaft two ends connects respectively triatic stay and jam nut, below horizontal brace pole socket, triangular truss is installed.
Compared with prior art, the beneficial effect that the present invention has is:
1, apparatus of the present invention adopt buffer rubber gasket to connect triatic stay and horizontal brace pole socket, buffer rubber gasket is rubber element, there is very large axial stiffness and very little rotational stiffness, efficiently solve the problem that is rigidly connected between existing railway truck triatic stay and horizontal brace pole socket, realize flexibly connecting between horizontal brace pole socket and triatic stay, improve the strained condition of triatic stay, reduce the probability of triatic stay fracture.
2, between adapter shaft and horizontal brace pole socket, adopt jam nut to be connected, efficiently solve the problem of bolt looseness between existing railway truck triatic stay and horizontal brace pole socket, realizing horizontal brace pole socket is connected with the Anti-extrusion between triatic stay, strengthen Joint strenght and rigidity in vehicle operating process, reduce the outer bulging deformation amount of side wall.
3, adopt triangular truss structure, effectively solved the outer excessive problem of bulging deformation of existing railway truck side wall, improve the safety and reliability of vehicle operating.
4, adopt one piece casting type strut socket, avoid connecting the welding of self, improve the strength and stiffness of strut socket, strengthen the good looking appearance of strut socket.

The specific embodiment
Referring to Fig. 1～Fig. 9, the present invention includes triatic stay 4 and horizontal brace pole socket 1, horizontal brace pole socket 1 is arranged on the side wall of lorry, and triatic stay 4 is supported on horizontal brace pole socket 1.Its gordian technique is that triatic stay 4 is connected by adapter shaft 6 with horizontal brace pole socket 1, adapter shaft 6 two ends are set with respectively buffer rubber gasket 2 and link stopper 3 successively, adapter shaft 6 two ends connect respectively triatic stay 4 and jam nut 5, and the use of buffer rubber gasket 2 has realized flexibly connecting between horizontal brace pole socket 1 and triatic stay 4; The use of jam nut 5 has realized the Anti-extrusion design between horizontal brace pole socket 1 and triatic stay 4.Triangular truss 7 is installed below horizontal brace pole socket 1.
Described horizontal brace pole socket 1 is provided with cover of dust 10, to avoid granular class goods to enter horizontal brace pole socket internal corrosion parts; The buffer rubber gasket 2 of adapter shaft 6 one end, link stopper 3 and jam nut 5 are positioned at cover of dust 10, make cover of dust also have locking function.
On the side wall of lorry and central sill, lower support seat 8 and central sill supporting seat 9 are installed respectively.
Described triangular truss 7 is intersected afterwards between two by upper hound 7.3, vertical strut 7.2 and lower hound 7.4 and connecting panel 7.1 is welded as a whole forms, with bolt, by connecting panel, triangular truss is connected with horizontal brace pole socket 1, lower support seat 8 and central sill supporting seat 9 again, jointly forms stable truss structure with triatic stay 4.
The present invention offers the first connecting bore 1.1 on horizontal brace pole socket 1, in order to be connected with adapter shaft 6; In horizontal brace pole socket 1 bottom, be provided with the second connecting bore 1.2, in order to be connected with triangular truss 7; On lower support seat 8, be provided with on the first riser 8.1, the first risers 8.1 and offer the first riser hole 8.2; On central sill supporting seat 9, be provided with on the second riser 9.1, the second risers 9.1 and offer the second riser hole 9.2; The first riser hole is to be all connected triangular truss 7 with the second riser hole.
Horizontal brace pole socket 1 of the present invention adopts mono-block cast, can reduce the globality of weld seam, raising product;
The present invention is applicable to railway truck as the connection between truck both walls, prevents that side wall is outer swollen.
Its installation process is:
1, first, cover of dust 10 is installed on horizontal brace pole socket 1;
2, secondly horizontal brace pole socket 1, lower support seat 8, central sill supporting seat 9 are assembled in to the relevant position of railway truck;
