Abstract
The present invention relates to equipment of railway transportation, particularly to truck brace apparatus.It includes 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 key technology is that triatic stay and horizontal brace pole socket connect by connecting axle, connects axle two ends suit buffer rubber gasket and link stopper successively respectively, connects axle two ends and connect triatic stay and locking nut respectively, at horizontal brace pole socket triangular truss mounted below.The invention have the advantages that: device adopts buffer rubber gasket to connect triatic stay and horizontal brace pole socket, buffer rubber gasket is rubber element, there is very big axial rigidity and only small rotational stiffness, efficiently solve the problem that is rigidly connected between existing railway freight-car triatic stay and horizontal brace pole socket, realize flexibly connecting between horizontal brace pole socket and triatic stay, improve the stress of triatic stay, reduce the probability of triatic stay fracture.
Description
Technical field
The present invention relates to equipment of railway transportation, particularly to truck brace apparatus.
Background technology
Truck is in running, and due to the lateral pressure effect of goods, side wall is certain outer swollen by occurring, and for ensureing traffic safety, is generally adopted the outer swollen shifting setting up pole structure to control side wall at present, adopts and be articulated and connected between strut and strut socket.The brace apparatus of this structure, side wall outer swollen time, owing to the joint gap at the place that is articulated and connected is too small, result in junction, to be supplied to the rotational stiffness of strut too small, therefore often there is strut socket place bolt looseness and the situation of strut fracture in brace apparatus, which not only improves the maintenance cost of brace apparatus, also reduce the safety that vehicle runs simultaneously.
Summary of the invention
The problem to be solved in the present invention is aiming at the deficiencies in the prior art and provides a kind of special brace apparatus of railway freight-car that can solve strut socket place bolt looseness and strut breakage problem easily.Its technical scheme is as follows:
It includes 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 key technology is that triatic stay and horizontal brace pole socket connect by connecting axle, connects axle two ends suit buffer rubber gasket and link stopper successively respectively, connects axle two ends and connect triatic stay and locking nut respectively, at horizontal brace pole socket triangular truss mounted below.
Compared with prior art, the invention have the advantages that:
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 big axial rigidity and only small rotational stiffness, efficiently solve the problem that is rigidly connected between existing railway freight-car triatic stay and horizontal brace pole socket, realize flexibly connecting between horizontal brace pole socket and triatic stay, improve the stress of triatic stay, reduce the probability of triatic stay fracture.
2, connect axle to be connected with adopting locking nut between horizontal brace pole socket, efficiently solve the problem of bolt looseness between existing railway freight-car triatic stay and horizontal brace pole socket, realize horizontal brace pole socket to be connected with the Anti-extrusion between triatic stay, strengthen the bonding strength in vehicle operation and rigidity, reduce the outer bulging deformation amount of side wall.
3, adopt triangular truss structure, efficiently solve the problem that the outer bulging deformation of existing railway freight-car side wall is excessive, improve the safety and reliability that vehicle runs.
4, adopt one piece casting type strut socket, it is to avoid connect the welding of self, improve the strength and stiffness of strut socket, strengthen the good looking appearance of strut socket.

Detailed description of the invention
Referring to Fig. 1～Fig. 9, the present invention includes triatic stay 4 and horizontal brace pole socket 1, and 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 key technology is triatic stay 4 and horizontal brace pole socket 1 connects by connecting axle 6, connect axle 6 two ends and be set with buffer rubber gasket 2 and link stopper 3 respectively successively, connecting axle 6 two ends and connect triatic stay 4 and locking nut 5 respectively, the use of buffer rubber gasket 2 achieves flexibly connecting between horizontal brace pole socket 1 and triatic stay 4；The use of locking nut 5 achieves the Anti-extrusion design between horizontal brace pole socket 1 and triatic stay 4.At horizontal brace pole socket 1 triangular truss 7 mounted below.
Described horizontal brace pole socket 1 is provided with dust cap 10, to avoid granular class goods to enter horizontal brace pole socket internal corrosion parts；Connect the buffer rubber gasket 2 of axle 6 one end, link stopper 3 and locking nut 5 and be positioned at dust cap 10 so that dust cap also has locking function.
The side wall and central sill of lorry are respectively mounted lower support seat 8 and central sill supporting seat 9.
Described triangular truss 7 is welded as a whole with connecting plate 7.1 after being intersected between two by upper hound 7.3, vertical strut 7.2 and lower hound 7.4 and forms, by connecting plate, triangular truss is connected with horizontal brace pole socket 1, lower support seat 8 and central sill supporting seat 9 with bolt again, is collectively forming stable truss structure with triatic stay 4.
The present invention offers the first connecting hole 1.1 on horizontal brace pole socket 1, in order to be connected axle 6 and connect；It is provided with the second connecting hole 1.2, in order to be connected with triangular truss 7 in horizontal brace pole socket 1 bottom；Lower support seat 8 is provided with the first riser 8.1, the first riser 8.1 is offered the first riser hole 8.2；Central sill supporting seat 9 is provided with the second riser 9.1, the second riser 9.1 is offered the second riser hole 9.2；First riser hole and the second riser hole are all connect triangular truss 7.
Horizontal brace pole socket 1 of the present invention adopts single-casting, can reduce weld seam, improve the globality of product；
The present invention is applicable to railway freight-car such as connection between truck both walls, it is prevented that side wall is outer swollen.
Its installation process is:
1, first, dust cap 10 is installed on horizontal brace pole socket 1；
Secondly 2, horizontal brace pole socket 1, lower support seat 8, central sill supporting seat 9 are assembled in the relevant position of railway freight-car；
3, by vertical strut 7.2, upper hound 7.3 and lower hound 7.4 are welded into triangular truss structure with connecting plate 7.1；
4, three connecting plates of triangular truss 7 are connected with bolt and nut with the second connecting hole 1.2 of horizontal brace pole socket bottom, the first riser hole 8.2 of lower support seat and the second riser hole 9.2 of central sill supporting seat respectively；
5, last, assemble triatic stay 4 as shown in Figure 9, connect axle 6, locking nut 5, buffer rubber gasket 2, link stopper 3 and horizontal brace pole socket 1.Make to connect the buffer rubber gasket 2 of axle 6 one end, link stopper 3 and locking nut 5 and be positioned at dust cap 10.
Use the present invention time, between railway freight-car both walls, horizontal brace pole socket should leave enough installing spaces.
