Abstract
The utility model relates to an arched cable bridge, wherein the centre of the bridge is an upward arched or trapezoidal bridge section; two ends of the arched or trapezoidal bridge section are provided with a suspending lazy arm or a column support arm. The utility model has the advantages of beautiful and simple cable installation without affecting the path of the cable installation, increases the space on the lower part of the bridge by using the arched bridge and improves the detection environment of the inspector.
Description
Technical field
The utility model relates to a kind of cable testing bridge device, relates in particular to a kind of arch formula cable testing bridge.
Background technique
Cable testing bridge is widely used in the power industry at present.Particularly electric substation's inner cable quantity is various, and direction of routing is complicated, and cable testing bridge uses to solve and much lays problem, makes cable laying more clear.
But the layout of cable testing bridge has certain restriction again; Be that cable testing bridge generally is installed in the cable half storey; The height of cable half storey is generally all lower, and personnel are just smaller in the space itself of installing, overhauling and making an inspection tour, and secondary crane span structure layer distance when arranging has the requirement of rules standard again.When in the cable half storey, laying like this, bottom crane span structure does not often meet the demands apart from the distance on ground, and personnel are very difficult when tour is passed through.
Summary of the invention
The purpose of the utility model is exactly in order to address the above problem, and a kind of arch formula cable testing bridge is provided, and this kind crane span structure has simple in structure, and is easy to use, can effectively improve cable testing bridge below personnel and make an inspection tour the problem through difficulty.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of arch formula cable testing bridge, arc or the trapezoidal crane span structure section of the centre of crane span structure for upwards arching upward, suspension arm or upright supports arm are established in the two ends of arc or trapezoidal crane span structure section.
Described arc or trapezoidal crane span structure section are provided with the wire earthed system.
Described suspension arm or upright supports arm link to each other with crane span structure through the pallet fixing device.
The pallet fixing device is that bolt, anchor such as buckle at the support fixed system of forming, and is used for supports such as support brachium pontis or arm and is connected with the direct of crane span structure.
The arch formula cable testing bridge personnel of being installed on of the utility model make an inspection tour the passage place, and when personnel maked an inspection tour, personnel were through convenient.
The beneficial effect of the utility model is: cable laying is attractive in appearance, succinct, does not influence the path of cable laying, and adopts the space of arch formula crane span structure rear axle stand below to increase, and has improved the personnel's that make an inspection tour maintenance environment.Under the constant basically situation of cost, as the user of service convenience is provided after using this crane span structure, embodied the theory that people-oriented, enlarged the Applicable scope that crane span structure lays.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein, 1. arc or trapezoidal crane span structure section 2. hang arm or upright supports arm, 3. pallet fixing device, 4. crane span structure connection set and fixed block, 5. earthed system.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
A kind of arch formula cable testing bridge, arc or the trapezoidal crane span structure section 1 of the centre of crane span structure for upwards arching upward, suspension arm or upright supports arm 2 are established in the two ends of arc or trapezoidal crane span structure section 1.
Described arc or trapezoidal crane span structure section 1 are provided with wire earthed system 5.
Described suspension arm or upright supports arm 2 link to each other with crane span structure through pallet fixing device 3.
Among Fig. 1, slot type or ladder type crane span structure directly link to each other with former crane span structure, use equivalent material.Make an inspection tour through the place personnel, crane span structure upwards arches upward on former level height basis, and to be angle be the oblique top of straight line or be arc.Arching upward is parallel to former crane span structure or maintenance arc again to the appropriate location, about 1000mm of length or radius are about 500mm, are angle again and are oblique below of straight line or arc, until former crane span structure level height.
Crane span structure uses trailing arm or column arm supports, uses fixed block such as pallet to fix, and the crane span structure joint uses connecting sheet etc. to connect, and establishes the earthed system such as annealed copperwire of ground terminal and 4 square millimeters on the crane span structure.
Claims (3)
1. an arch formula cable testing bridge is characterized in that, arc or the trapezoidal crane span structure section of the centre of crane span structure for upwards arching upward, and suspension arm or upright supports arm are established in the two ends of arc or trapezoidal crane span structure section.
2. arch formula cable testing bridge according to claim 1 is characterized in that, described arc or trapezoidal crane span structure section are provided with the wire earthed system.
