a main object of the utility model is to provide a big span cable testing bridge of ladder formula, through be equipped with the gland plate on the crane span structure, be used for preventing the entering of dust, influence the pleasing to the eye of crane span structure, the surface mounting of bottom plate has a PVC board, can play fine dampproofing dehumidification's effect, the life of cable has been prolonged, through be equipped with a plurality of fixed covers above the crosspiece, the position of accuse cable that can be fine, it piles up to place the cable, the crane span structure atress is uneven, thereby lead to the damage of crane span structure, the life of crane span structure and annex has been improved greatly, the inside of fixed cover is inlayed and is had the insulating layer, play fine thermal-insulated effect, can effectively solve the problem in.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

The utility model provides a big span cable testing bridge of ladder formula, includes first curb plate, second curb plate, crosspiece and bottom plate, first curb plate bottom is passed through bottom plate fixed connection the second curb plate, first curb plate with the gland plate is installed to second curb plate top, the connection can be dismantled on the bottom plate top the crosspiece, crosspiece surface buckle is connected with a plurality of fixed covers, the insulating layer is inlayed to fixed cover inside wall.

Further, mounting holes are formed in the two ends of the surfaces of the first side plate and the second side plate.

Further, a layer of PVC plate is embedded on the surface of the bottom plate.

Further, the surfaces of the first side plate and the second side plate are coated with an anticorrosive layer.

Compared with the prior art, the utility model discloses following beneficial effect has:

The utility model discloses a be equipped with the gland board on the crane span structure, be used for preventing the entering of dust, influence the pleasing to the eye of crane span structure, the surface mounting of bottom plate has a PVC board, can play fine dampproofing dehumidification's effect, the life of cable has been prolonged, through be equipped with a plurality of fixed covers on the crosspiece, the position of accuse cable that can be fine, it piles up to place the cable, the crane span structure atress is uneven, thereby lead to the damage of crane span structure, the life of crane span structure and annex has been improved greatly, the inside of fixed cover is inlayed and is had the insulating layer, play fine thermal-insulated effect.
