Description

A kind of self-locking cable testing bridge
Technical field
The utility model relates to a kind of cable testing bridge, specifically refers to a kind of self-locking cable testing bridge.
Background technology
In power engineering, cable testing bridge, as the supporting body of cable laying, has the function of protection cable simultaneously.Traditional cable testing bridge is generally corresponding crane span structure and cover plate are made in advance by size, then according to the condition of job site, corresponding crane span structure and cover plate is carried out combining assembling and forms the cable testing bridge being used for cable laying.So, for the cable testing bridge of horizontal positioned, cover plate just in time covers crane span structure, and cable protection inside, problem is little.But for the vertical crane span structure placed, because of the impact that mounting condition, technique and inside cable are how many, may there is the situation of defective tightness in the combination between cover plate and crane span structure; of long duration or be subject to external force impact; cover plate may fall down, and loses defencive function, also unsightly.In order to solve this problem, people create a crane span structure with buckle, need to weld buckle in advance.Such cable testing bridge makes loaded down with trivial details, and cost is higher.In addition, because the bonding area of buckle and crane span structure and cover plate is little, As time goes on, easily occur aging and cause the situation of structural failure.Therefore, carrying out solution for above-mentioned prior art Problems existing is research purpose of the present utility model.
Utility model content
For above-mentioned the deficiencies in the prior art part, the utility model is to provide a kind of self-locking cable testing bridge, effectively can solve above-mentioned prior art Problems existing.
The technical solution of the utility model is: a kind of self-locking cable testing bridge, comprise crane span structure, cover plate and self-locking mechanism, described cover plate is articulated with on described crane span structure by corresponding hinge, the centre position of the side of the not hinged described cover plate of described crane span structure is provided with a cover plate location notch, the arranged outside of described cover plate location notch has described self-locking mechanism, described self-locking mechanism comprises the self-locking body be fixed in outside described cover plate location notch, self-lock rod is socketed with in described self-locking body, the outside of described self-lock rod is connected with positioning cap, the side that described self-lock rod does not connect positioning cap is connected with self-locking spring, described self-locking spring pressurizing unit is in described self-locking body, the side that described cover plate is not hinged to described crane span structure is provided with a location-plate on the position corresponding with described cover plate location notch, and described location-plate is provided with a location hole on the position corresponding with the self-lock rod of described self-locking mechanism.
Advantage of the present utility model: (1) the utility model adopts self-locking mechanism to position cover plate, effectively prevent the combination between cover plate and crane span structure from occurring the situation of defective tightness, this crane span structure because of the passing of time or can not be subject to external force impact, and occurs the accident that cover plate falls down.(2) action of self-lock rod is controlled by positioning cap, all very convenient for opening with locking action of cover plate, effectively can improve installation effectiveness, and be more suitable for the repair and maintenance operation in later stage.(3) the utility model also has making simply, with low cost, produces advantage easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cutaway view of the present utility model.
Embodiment
Now embodiment is described in further detail structure of the present utility model by reference to the accompanying drawings for the ease of it will be appreciated by those skilled in the art that:
With reference to Fig. 1-2, a kind of self-locking cable testing bridge, comprise crane span structure 2, cover plate 1 and self-locking mechanism 3, described cover plate 1 is articulated with on described crane span structure 2 by corresponding hinge 4, the centre position of the side of the not hinged described cover plate 1 of described crane span structure 2 is provided with a cover plate location notch 21, the arranged outside of described cover plate location notch 21 has described self-locking mechanism 3, described self-locking mechanism 3 comprises the self-locking body 31 be fixed in outside described cover plate location notch 21, self-lock rod 32 is socketed with in described self-locking body 31, the outside of described self-lock rod 32 is connected with positioning cap 33, the side that described self-lock rod 32 does not connect positioning cap 33 is connected with self-locking spring (mark), described self-locking spring pressurizing unit is in described self-locking body 31, the side that described cover plate 1 is not hinged to described crane span structure 2 is provided with a location-plate 11 on the position corresponding with described cover plate location notch 21, and described location-plate 11 is provided with a location hole on the position corresponding with the self-lock rod 32 of described self-locking mechanism 3.
The utility model adopts self-locking mechanism 3 pairs of cover plates 1 to position, and effectively prevents the combination between cover plate 1 and crane span structure 2 from occurring the situation of defective tightness, and this crane span structure because of the passing of time or can not be subject to external force impact, and occurs the accident that cover plate 1 falls down.Controlled the action of self-lock rod 32 by positioning cap 33, for cover plate 1 open with lock all very convenient.During locking, self-lock rod 32 is positioned in the location hole of described cover plate 1; When needing to open, by positioning cap 33, self-lock rod 32 is pulled away from the location hole of cover plate 1, just can realizes opening.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
