Abstract
The invention relates to a carrier cable binaural wedge-shape clamp suitable for die forging to completely solve the potential risk of casting binaural wedge-shape clamp in current electrified railways, and at the same time increase production efficiency, reduce production costs and ensure operation safety of electrified railway. The die forging carrier cable binaural wedge-shape clamp is made by symmetrical binaural and a wedge chamber into a whole. Reinforcing ribs are coated on the outside of the binaural, and the binaural is connected to the wedge chamber in the form of circular arc transition. The joint position between the binaural and the wedge chamber is fastened by connection reinforcing ribs, and the bottom of the wedge chamber is fastened by wedge chamber reinforcing ribs. By changing the structure of the binaural wedge-shape clamp, the carrier cable binaural wedge-shape clamp is suitable for forging process of preparation and completely eliminates different potential safety hazard of the existing binaural wedge-shape clamp.
Description
Technical field
The present invention relates to the improvement, particularly catenary ears wedge clamp of electrified high-speed railway OCS Messenger Wire terminal anchoring bracket upper bed-plate.
Background technology
Existing electrification railway contact net termination fitting for catenary is casting, the wire clamp of casting because the particularity of Structure and energy to cause this product not only to cast finished product low, efficiency is low, and sand holes can be there are in inside, pore, the foundry defects such as shrinkage porosite, the yield rate causing product is like this low, ensure that product design must increase the operation of foundry goods flaw detection to ensure the reliability of product, reduce the capacity rating of product, add productive costs, even if the more important thing is under these circumstances, because batch is large and flaw detection is too high to the requirement of equipment and personnel, each production unit technical capacity differs, cause also having off gauge supply unavoidably to reach the standard grade.Along with improving constantly of electrified railway running velocity, as anchoring class part important in electrified railway, casting ears wedge clamp becomes a potential potential safety hazard of electrified railway.
Summary of the invention
The present invention seeks to the catenary ears wedge clamp designing a kind of applicable die forging, thoroughly to solve the potential safety hazard of casting ears wedge clamp in present electrified railway, increase production efficiency simultaneously, reduce productive costs, ensure electrified railway safe operation.
Technical scheme: die forging catenary ears wedge clamp, it makes one by the wedge chamber bottom symmetrically arranged ears and its, and outside ears, be shaped with ears reinforced rib, arc transition is made in the connection in ears and wedge chamber, be shaped with connection strengthening rib in the outside, junction in ears and wedge chamber, be shaped with wedge chamber reinforced rib in bottom, wedge chamber.
The present invention, by changing ears wedge clamps structure, makes its applicable Forging Technology preparation, has thoroughly stopped the appearance of the potential safety hazards such as airhole in existing ears wedge clamp.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 birds-eye view of the present invention.
Detailed description of the invention
As shown in Figure 1-2, die forging catenary ears wedge clamp, it makes one by symmetrically arranged ears 5 and the wedge chamber 6 bottom it, and ears reinforced rib 1 is shaped with outside ears 5, arc transition 2 is made in the connection in ears and wedge chamber, be shaped with connection strengthening rib 3 in the outside, junction in ears and wedge chamber, be shaped with wedge chamber reinforced rib 4 in bottom, wedge chamber.
Above structure achieves can change into Forging Technology by original foundry technique, because Forging Technology is forged and pressed by monoblock steel wool base and forms, stop the possibility that in inner structure, airhole occurs, and add overall mechanical strength by die forging extruding, the reliability in order to ensure intensity has carried out following improvement to structure:
First, original foundry technique is determined to change into Forging Technology, because Forging Technology is forged and pressed by monoblock steel wool base and forms, stop the possibility that in inner structure, airhole occurs, and add overall mechanical strength by die forging extruding, the reliability in order to ensure intensity has carried out following improvement to structure:
A, in order to strengthen the resistance to tension of forging ears, strengthens the safe reliability of parts, increases reinforced rib 1 outside ears.
B. use arc transition 2 in the junction in ears and wedge chamber, decrease stress and concentrate, prevent stress and concentrate cause stressed to occur crackle.
C. increase reinforced rib 3 in the junction in ears and wedge chamber, strengthen the steadiness in wedge chamber on the one hand, be used for the transition that ears open shelves and wedge chamber thickness on the other hand, reduce and concentrate and complex process because ears bend the stress caused at all, increase the safety of wire clamp.
D. increase reinforced rib 4 equally in bottom, wedge chamber, from upper and lower 2 places, strengthened in whole wedge chamber, circular reinforced rib has disperseed stress simultaneously, ftractures in the more effective wedge chamber that prevents.
The present invention changes production technology and the structure of original wire clamp, has thoroughly stopped the appearance of the potential safety hazard such as airhole in ears wedge clamp.Product of the present invention has carried out a series of performance test according to the test criteria of electrified railway to wire clamp, can reach the requirement for ears wedge clamp product in professional standard completely, and solve the issuable defect of all cast product.
