Abstract
The utility model discloses an automatic neutral-section passing mounting bracket for locomotives. In order to solve the problem that the existing mounting bracket of a main-line harmony freight electric locomotive automatic neutral-section passing device is easy to crack, the locomotive automatic neutral-section passing mounting bracket comprises a bottom plate, a cylinder and a bending plate, wherein holes are formed in the bottom plate and the bending plate and are communicated with the cylinder; and the bottom and the cylinder are in circular arc transition connection, and the bending plate and the cylinder are in circular arc transition connection. On the premise that the original interface is unchanged, the automatic neutral-section passing mounting bracket for locomotives has strong carrying capacity and a reliable structure. The locomotive automatic neutral-section passing mounting bracket is simple in casting process, and the batched manufacturing cost is obviously reduced.
Description
Technical field
The utility model relates to the rail locomotive vehicle and manufactures and designs the field, is specially the automatically undue phase mounting bracket of a kind of locomotive.
Background technology
The mounting bracket of the harmonious shipping power car automatic passing phase insulator device of existing main line generally is mounted on the axlebox rod seat of framework, is exactly this mounting means such as the automatically undue phase mounting bracket of HXD1B, HXD1C electric locomotive.As shown in Figure 1, the mounting bracket of this automatic neutral-section passing device is generally welded structure, be welded successively by base plate 7, cylinder solid drawn pipe 8, bending plate 9, and all be welded with small gusset 10 in the junction of base plate 7 and junction, cylinder solid drawn pipe 8 and the bending plate 9 of cylinder solid drawn pipe 8.
Show that through operation above-mentioned this structure crackle at first occurs in the wedge angle commissure of small gusset 10 and base plate 7 easily, along with the continuous expansion of crackle, finally makes whole base plate be fractured into two.
The utility model content
The shortcoming that ftractures appears easily at the mounting bracket of the harmonious shipping power car automatic passing phase insulator device of existing main line, the utility model aims to provide the automatically undue phase mounting bracket of a kind of locomotive, this mounting bracket is keeping under the constant prerequisite of original interface stronger, the reliable in structure of load-carrying capacity.
To achieve these goals, the technical scheme that adopts of the utility model is:
The automatically undue phase mounting bracket of a kind of locomotive comprises base plate, cylinder and bending plate; Its constructional feature is all to have the hole on described base plate and the bending plate, this hole and the perforation of described cylinder; Described base plate is arc transition with cylinder junction, bending plate with the cylinder junction and is connected.
Below be the technical scheme of further improvement of the utility model:
For the cable that too is connected is automatically installed firmly, described bending plate is provided with the cable ply-yarn drill fulcrum is installed.
Described base plate thickness is at least 16mm.Described bending plate thickness is at least 10mm.
In order to remedy the influence of wheel wear and manufacturing errors, described bending plate bottom is connected with regulating plate, and the automatic neutral-section passing device height to the top of rail is remained in the designing requirement size.
By said structure, mounting bracket of the present utility model has been done the series of optimum improvement on the basis of original design, and calculated stress significantly reduces, and load-carrying capacity is stronger, reliable in structure.Have following technical characterictic:
Mounting bracket described in the utility model is cast an integral body with base plate, cylinder, bending plate, has avoided the danger of cracking easily of light gauge welding weld seam;
Mounting bracket described in the utility model can reduce deadweight on the one hand with top base plate and the equal perforate up/down perforation of bottom bending plate, can simplify foundry technique on the other hand;
Concentrate in order to reduce casting stress, mounting bracket described in the utility model has fallen the circular arc of a R20mm in base plate and cylinder junction, has fallen the circular arc of a R10mm in bending plate and cylinder junction;
Mounting bracket of the present utility model has been done the series of optimum improvement on the basis of existing structure: 1) at first, original welded structure should be casting structure; 2) the original small gusset of cancellation; 3) base plate thickness is increased to 16mm by original 12mm; 4) the cylinder thickening strengthens; 5) bending plate is increased to 10mm by original 8mm.6) increase the rounding transition between base plate, bending plate and the cylinder, reduce stress and concentrate.
Show that through calculating new type auto undue phase mounting bracket stress significantly reduces, load-carrying capacity is stronger, reliable in structure.Simultaneously, automatically undue phase mounting bracket foundry technique of the present utility model is simple, and manufacturing cost significantly reduces in batches.
Compared with prior art, the beneficial effects of the utility model are: automatically undue phase mounting bracket described in the utility model has overcome crackle appears in conventional stent easily between small gusset and base plate shortcoming, stress significantly reduces, and load-carrying capacity is stronger, reliable in structure.Simultaneously, automatically undue phase mounting bracket foundry technique of the present utility model is simple, and manufacturing cost significantly reduces in batches.
Below in conjunction with drawings and Examples the utility model is further elaborated.
