Description
Technical field
The utility model relates to a kind of lorry brake device, particularly about a kind of railway truck release valve pull bar.
Background technology
Release valve pull bar is widely used in domestic and international railway truck, it is the main operating parts realizing hand relieving in vehicle air brake systems, release valve pull bar forms with the release valve of 120 type truck air control cock, DB60 type control cock, ABDX type control cock etc. and is directly connected, to realize vehicle hand relieving function.The layout of release valve pull bar should be convenient to the safe in operation of surface personnel, because of the improper release phenomenons that cause such as retardances when also will avoid operating.
The structure of the layout of existing release valve pull bar and design Main Basis railway truck and determining, is arranged in the middle part of truck body structure or is arranged in the end of truck body structure, and being fixed by associate member.Some vehicles are owing to being subject to body construction restriction, and control cock position is positioned at curb girder side, and cause release valve pull bar two differences in length comparatively large, a short length is too short, cannot use traditional release valve pull bar form.
Summary of the invention
For the problems referred to above, the purpose of this utility model provides one to be applicable to control cock and is arranged on curb girder side, without the short and small type release valve pull bar of space mounting associate member.
For achieving the above object, the utility model takes following technical scheme: a kind of railway truck release valve pull bar, is characterized in that, this release valve pull bar comprises: a draw ring; One suspension ring being fixedly installed on described draw ring top, arrange a circular hole above described suspension ring; And a spring cotter for making described release valve pull bar be connected with described control cock with the circular hole in control cock through the circular hole of described suspension ring.
Preferably, described draw ring adopts the trapezoidal draw ring being convenient to operated by personnel.
Preferably, described suspension ring by a Line Segment and two halves circle segments one-body molded, described Line Segment two ends arrange described semi-circular section respectively, and the described circular hole be positioned at above described suspension ring is made up of the semi-circular section and second half circle segments identical with this semi-circular section diameter being positioned at described suspension ring top.
Preferably, described draw ring and described suspension ring adopt welding manner to be fixed.
The utility model is owing to taking above technical scheme, it has the following advantages: draw ring welded top of the present utility model fixes suspension ring, circular hole is provided with above suspension ring, control cock is connected with release valve pull bar of the present utility model through the circular hole of release valve handle circular hole and suspension ring by spring cotter, when not needing hand relieving, draw ring and suspension ring nature, perpendicular to car body, are fixed without the need to associate member, decrease the number of parts of design, be conducive to the saving of cost; When needs hand relieving, only draw ring and suspension ring need be carried and pulling in level attitude, simple to operate, be easy to processing, result of use is good, can be widely used in the release valve pull bar making of railway truck.
Accompanying drawing explanation
Fig. 1 is the utility model schematic front view;
Fig. 2 is the utility model schematic top plan view;
In figure, mark is as follows: 1 draw ring, 2 suspension ring, 21 Line Segment, 22 semi-circular section, 3 spring cotters, 4 circular holes, 5 control cock.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description is carried out to the utility model.But should be appreciated that being provided only of accompanying drawing understands the utility model better, they not should be appreciated that paired restriction of the present utility model.
As shown in Figure 1 and Figure 2, the railway truck release valve pull bar that the utility model provides, comprise draw ring 1, suspension ring 2 and a spring cotter 3, draw ring 1 top is fixedly installed suspension ring 2, arrange a circular hole 4 above suspension ring 2, spring cotter 3 makes release valve pull bar be connected with control cock 5 through the circular hole 4 on suspension ring 2 with the circular hole on the release valve handle of existing control cock 5.
In a preferred embodiment, draw ring 1 can adopt the trapezoidal draw ring being convenient to operated by personnel.
In a preferred embodiment, suspension ring 2 can by a Line Segment 21 and two halves circle segments 22 one-body molded, Line Segment 21 two ends arrange semi-circular section 22 respectively, and the circular hole 4 being positioned at suspension ring 2 can be made up of the semi-circular section 22 and second half circle segments identical with this circle segments diameter being positioned at suspension ring top.
In a preferred embodiment, draw ring 1 and suspension ring 2 can adopt welding manner to be fixed.
When the utility model uses, spring cotter 3 is adopted to be connected with release valve pull bar of the present utility model by the S. A. release valve of control cock 5 through the circular hole 4 above the circular hole of the S. A. release valve handle of railway truck control cock 5 and suspension ring 2; When not needing hand relieving, draw ring 1 and suspension ring 2 nature, perpendicular to lorry body, are fixed without the need to associate member, are decreased the number of parts of design, be conducive to the saving of cost; When needs hand relieving, only draw ring 1 and suspension ring 2 need be carried and pulling in level attitude, simple to operate.
The various embodiments described above are only for illustration of the utility model; wherein the structure of each parts, connection mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
