Abstract
The utility model provides a double-lug wedge-shaped cable clamp used for a high speed railway and solves the problems existing in the prior art. The double-lug wedge-shaped cable clamp comprises a cable clamp body, wherein the cable clamp body is provided with a conical unilateral wedge cavity; a tooth-shaped wedge which is similar to the wedge cavity in shape is mounted in the wedge cavity; a pair of protruding lugs is arranged on the cable inlet end of the wedge cavity and is used for being connected with the external; a connecting body is mounted on the pair of protruding lugs. The double-lug wedge-shaped cable clamp has the beneficial effects that the structure is simple, the mounting mode of parts is simple and convenient, the site construction is facilitated, components are few, the forging production is suitable, the mechanical property is stable, and the use risk is greatly reduced.
Description
Technical field
The utility model ears wedge clamp belongs to applied to high-speed railway touching net parts technical field, and relate to contact system clue anchoring device foundry technique and change Forging Technology into, and the change of External Shape.
Background technology
Last century six, the seventies, was China's Electrified Railways first stage of construction, and elements of contacting net is simple in structure, and production technology is coarse, and parts performance is lower.After the nineties, promote casting on a large scale and change forging process, aluminum alloy part starts to adopt Low Pressure Casting Technology, and the parts such as hanger ear, electrically connecting clamp, steady ear adopt copper alloy precision drop forging, and steady arm adopts band to prevent raising spacing aluminum alloy steady arm in a large number.But limited by working condition, ears wedge clamp still adopts Foundry Production, cast article rustic, intensity is lower, is difficult to adapt to the situation of railway high speed development.
In national < <, the long-term railway network is planned in > > scheme, the developing direction that proposes state-owned railroads transportation is towards heavy duty and future development at a high speed, push forward technology innovation comprehensively, using improving domestic manufacture of key equipment level, as an important content of railway construction from now on, grab.The terminal anchoring clamp mounting means using in China Express Railway is at present comparatively loaded down with trivial details, is unfavorable for site operation; And the ears wedge clamp simple installation that common railway is used but adopt foundry engieering to produce, because foundry goods self-defect is as the existence of pore, shrinkage porosite, slag inclusion etc., make part machinery intensity discreteness larger, application risk is higher, cannot in high speed railway, use.
Summary of the invention
The object of the utility model part design invention, is to provide a kind of used for high-speed railway ears wedge clamp, has solved problems of the prior art.
High speed railway ears wedge clamp, has wire clip body, and wire clip body, with the monolateral wedge of taper chamber, is equipped with the profile of tooth chock similar to wedge cavity shape in wedge chamber; In end of incoming cables, wedge chamber, there are outstanding ears for being connected with outside; On outstanding ears, connector is housed.
Described connector consists of bolt pin, spring cotter, nut.
The beneficial effect of the utility model ears wedge clamp is: simple in structure, part mounting means is easy, is applicable to site operation; Parts are few simultaneously, are applicable to forging, and stable mechanical performance, significantly reduces application risk.
Accompanying drawing explanation
Fig. 1 is high speed railway ears wedge clamp structural representation.In figure, 1. ears wedge clamp body (shell), 2. profile of tooth chock, 3. bolt pin, 4. spring cotter, 5. nut.
The specific embodiment
As Fig. 1 has provided the utility model specific embodiment, wire clip body 1 (shell), with a taper (monolateral) wedge chamber, has outstanding ears for being connected with outside in end of incoming cables, wedge chamber; Part chock is similar to wedge cavity shape.This part adopts the pattern of ears wedge clamp body and chock combination, will connect clue through the body wedge chamber that chock is housed, and tension clue, steps up to reach the effect of fastening clue naturally by chock and wedge chamber.The mode that this part is connected with bolt pin by ears is fixedly connected with camp site anchor fitting.
Claims (2)
1. high speed railway ears wedge clamp, has wire clip body (1), it is characterized in that wire clip body (1), with the monolateral wedge of taper chamber, is equipped with the profile of tooth chock (2) similar to wedge cavity shape in wedge chamber; In end of incoming cables, wedge chamber, there are outstanding ears for being connected with outside; On outstanding ears, connector is housed.
2. high speed railway ears wedge clamp according to claim 1, is characterized in that described connector consists of bolt pin (3), spring cotter (4), nut (5).
