Description
Technical field
The utility model relates to a kind of air inlet system of the air bellow for railcar, belongs to guideway vehicle shock absorption device design field.
Background technology
In the railcar design, for effectively improving travelling comfort, the secondary suspension of all kinds railcar has all adopted air bellow as damper element at present.For guaranteeing the relatively stable of height of floor from rail top, along with the variation of passenger capacity, the internal pressure of air bellow need to be adjusted in real time, now needs to be inflated and bleed air operation by air intake structure.For guaranteeing that this inflation/deflation process carries out smoothly, just need a set of failure-free air intake structure.
Railcar air bellow air intake structure also has various ways, and early stage, mode more commonly used was, by welding manner, air inlet pipe is welded in to the car body sleeper beam, but, due to the complexity of welding, the weld defect of generation is difficult to find sometimes.For the uncertain factor of eliminating welding and the reasons such as comfort feature of installation and maintenance, a kind of air bellow air intake structure of novel applicable Welded sleeper beam structure has been proposed.
the utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, proposes a kind of air inlet system of the air bellow for railcar, has convenient for installation and maintenancely, and difficulty of processing is lower, the characteristics that reliability is strong.
In order to solve above technical matters, the air inlet system of the air bellow for railcar that the utility model provides, comprise the air inlet cover and be fixedly connected on the air inlet pipe that described air inlet puts, described air inlet puts has the mounting hole be connected through fastener and outside sleeper beam, has the anchor fitting be connected with car body on the overhanging end of described air inlet pipe.
The aforesaid air inlet system of the air bellow for railcar, described air inlet cover has the cylinder negative thread, and the front end of described air inlet pipe has the circular cone outside thread, and described air inlet pipe and air inlet cover are connected and fixed by described cylinder negative thread and circular cone outside thread.
The aforesaid air inlet system of the air bellow for railcar, be filled with sealant between described cylinder negative thread and circular cone outside thread, usually selects happy safe 577 sealants, can fully guarantee the sealing of admission line.
The aforesaid air inlet system of the air bellow for railcar, described mounting hole is counter sink, coordinates flathead screw, be installed to sleeper beam after empty spring face integral body there is better planeness.
Further, the aforesaid air inlet system of the air bellow for railcar, described anchor fitting comprises welding support and pipe clamp, and described welding support one end is fixedly connected with car body, and the other end is fixedly connected with the pipe clamp on being arranged on air inlet pipe.
The beneficial effects of the utility model are: the utility model is assembled fixing by thread matching structure, and is sealed by sealant, makes structure installation, easy to maintenance, and difficulty of processing is lower, and reliability is strong, has good application prospect.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the present embodiment scheme of installation.
The specific embodiment
A kind of air inlet system of the air bellow for railcar that the present embodiment provides, structure as depicted in figs. 1 and 2, comprise air inlet cover 2 and be fixedly connected on the air inlet pipe 1 that air inlet puts, air inlet puts has the countersunk head mounting hole 3 be connected through fastener and outside sleeper beam, coordinate flathead screw, be installed to sleeper beam after empty spring face integral body there is better planeness; Have the anchor fitting be connected with car body on the overhanging end of air inlet pipe, anchor fitting comprises welding support 4 and pipe clamp 5, and welding support 4 one ends are fixedly connected with car body 6, and the other end is fixedly connected with the pipe clamp 5 on being arranged on air inlet pipe; The air inlet cover has the cylinder negative thread, the front end of air inlet pipe has the circular cone outside thread, air inlet pipe and air inlet cover are connected and fixed by cylinder negative thread and circular cone outside thread, are filled with happy safe 577 sealants between cylinder negative thread and circular cone outside thread, can fully guarantee the sealing of admission line.
When the present embodiment is installed, at first the air inlet cover is installed on sleeper beam, then air inlet pipe is screwed into to the air inlet cover, in installation process, threaded portion applies screw thread fastening glue.After air inlet pipe installs, overhanging end is tightened in to the installation that completes air intake structure on anchor fitting by screw bolt and nut.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
