Abstract
The utility model discloses a connecting and locking device for a flexible guard rail on a high-grade highway, which comprises a steel cable which needs to be connected with and a support post. The utility model is characterized in that the outer surface of a taper screw bolt is provided with a conical surface which is provided with threads, the inner part of the taper screw bolt is provided with a hole which is used for being passed through by the steel cable which needs to be connected with, a locking nut is sheathed on the conical surface of the taper screw bolt and can be cooperated with external threads of the taper screw bolt, an elastic plate is arranged between the support post and the taper screw bolt and a hole which is used for being passed through by the steel cable which needs to be connected with is arranged on the elastic plate. The connecting and locking device of the utility model has the advantages of simple structure, low cost, convenient installation, and easy maintenance; meanwhile, the utility model can be automatically suitable for the heat expansion and cold contraction of the steel cable by the flexibility of a steel plate spring. Thereby, the whole flexible guard rail can be in a better state.
Description
Technical field
The utility model relates to a kind of locking, linkage, and especially locking is used for the connection locking device of the steel cable of highway flexible anti guardrail.
Background technology
Along with the building up in a large number, be open to traffic of speedway, the freeway net of galloping is formed gradually; Simultaneously,, improved current condition greatly, the speed per hour of automobile also is greatly improved by transformation to original key highways such as national highway, provincial highways.
Because the raising of car speed has correspondingly increased the traffic safety accident; In order to reduce the loss that various security incidents cause, all to set up protective guard in the highway both sides.In the prior art, the highway protective guard has the rigid protective guard and two kinds of the flexible safety fences that adopts wire rope that adopts steel plate; The flexible anti guardrail is to adopt many wire rope, utilizes linkage that wire rope is fixed on support column (reinforced concrete post, channel column etc.); And linkage commonly used (casting concrete on the ground normally, one on the pull bar that connects usefulness is imbedded in the mixed casting soil, the other end links together with wire rope through take-up etc. again), be called the disclosed scheme of the Chinese utility model patent technology the inside that " flexible safety fence ", the patent No. are ZL00219350.7 as name, just adopt cable connector to be connected with earth anchor with turnbuckle, preloader, earth anchor is adorned the back of the body with in aggregates being connected of roadbed (concrete); The deficiency of this kind linkage mainly contains: 1, make, install complicated, trouble, when needing to change because of be damaged, fracture etc. especially, more feel inconvenient; 2, the elongation that causes because of expanding with heat and contract with cold of wire rope or the amount of contraction are bigger, and especially when whole length of steel wire rope was very long, elongation or the amount of shrinking were more; This kind linkage can't adapt to expanding with heat and contract with cold of wire rope by the mode of self regulating, and must adjust by external force, is very inconvenient in the use.
Summary of the invention
The utility model is at the above deficiency of existing flexible safety fence linkage, provide a kind of simple in structure, can adapt to the connection locking device that wire rope expands with heat and contract with cold automatically.
The technical solution of the utility model: the connection locking device of high-grade highway flexible anti guardrail, comprise and wait to connect wire rope and support column, its improvements are: the external surface of taper bolt is provided with taper surface, on this taper surface screw thread is arranged, the inside of taper bolt is provided with for the described hole of waiting to connect steel wire penetrating; Locking nut is enclosed within on the taper surface of taper bolt, can match with the external screw thread of taper bolt; Between described support column and taper bolt, be provided with elastic plate, have on the elastic plate for the described hole of waiting to connect steel wire penetrating;
Described elastic plate is a leaf spring.
Connection locking device of the present utility model, simple in structure, low cost of manufacture; Easy for installation, maintenance easily; Simultaneously, by the retractility of leaf spring, can adapt to wire rope automatically and expand with heat and contract with cold, thereby make whole flexible safety fence be in preferable state.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is the utility model structure diagram.
The specific embodiment
In figure, 1-wire rope to be connect, 2-support column, 3-taper bolt, 4-locking nut, 5-elastic plate.
Connection locking device of the present utility model comprises and waits to connect wire rope 1 and support column 2, waits that the two ends that connect wire rope 1 pass respectively in the hole of two support columns 2, is the annexation of an end and the support column 2 of wire rope 1 shown in the accompanying drawing.Support column 2 can have enough intensity for channel-section steel, reinforced concrete post etc., and an end is embedded in below the face of land, plays support, fixedly the effect of wire rope 1 gets final product.The external surface of taper bolt 3 is provided with taper surface, has certain taper, and screw thread is arranged on the taper surface, and there is through hole (centre bore) inside of taper bolt 3, passes for wire rope 1.On the endoporus of locking nut 4 internal thread is arranged, locking nut 4 can be enclosed within on the taper surface of taper bolt 3, and the internal thread of locking nut 4 can match with the external screw thread on the taper bolt 3, thereby plays the effect of locking.There is through hole elastic plate 5 inside, pass for wire rope 1, are arranged between support column 2 and the taper bolt 3, and elastic plate 5 has certain elasticity, has certain retractility; Promptly, when wire rope 1 shrinks or extends because of expanding with heat and contract with cold, shrink or extend the active force that produces and act on elastic plate 5, elastic plate 5 produces and shrinks or extend (its elongation is because effect power has thereon diminished) accordingly, thereby makes whole device be in preferable state; Adapt to the effect of expanding with heat and contract with cold of wire rope 1 by the retractility of elastic plate 5, make whole device be in preferable state, elastic plate 5 can be an illustrated curved plate, contacts with support column 2 or taper bolt 3 with arcwall face; Also the leaf spring (leaf spring) that can use for automobile shock etc. contacts with support column 2 or taper bolt 3 with arcwall face equally.
Operating principle of the present utility model: will wait to connect in the endoporus that wire rope 1 passes support column 2, elastic plate 5, taper bolt 3, and locking nut 4 will be enclosed within on the taper surface of taper bolt 3; Tighten locking nut 4 with machine, locking nut 4 mobile in taper bolt 3 (illustrating direction to the right) is just oppressed taper bolt 3 simultaneously and is inwardly shunk, and makes taper bolt 3 clamp treating in it and connects wire rope 1, thereby play the effect that links together, also locks; Elastic plate 5 has certain elasticity, can produce corresponding the contraction or elongation along with the size of active force; As, wait to connect wire rope 1 because of cooling or when being subjected to the external force effect and shrinking, elastic plate 5 is subjected to corresponding pulling force, and curved elastic plate 5 shrinks; And when waiting to connect wire rope 1 and extending because of meeting heat, the active force that elastic plate 5 is subjected to alleviates, curved elastic plate 5 corresponding elongations; This device can adapt to above two states, thereby make whole flexible safety fence be in preferable state automatically by the contraction or the elongation of elastic plate 5.
