The advantage that this reinforcement electric cable crane span structure has is as follows:
(1) not only alleviating the overall weight of this reinforcement electric cable bridge by arranging left crane span structure hollow tube and right crane span structure hollow tube, is also that its structure is more stable.
(2) existing reinforcement electric cable crane span structure can be solved well there is structural unstable problem by arranging right cross spud pile and left cross spud pile.
(3) extruding that also can prevent between cable to the suspension effect that is separated of cable can not only be played by arranging right hook and left hook.
(4) not only can reinforce reinforcement electric cable crane span structure internal structure further while not blocking the circulation of this reinforcement electric cable crane span structure inner air by arranging demarcation strip and hollow peg, and the effect of cable suspension can be played.
(5) achieving the detachable structure of this reinforcement electric cable crane span structure by arranging right crane span structure and left crane span structure, facilitating and inspection and maintenance is carried out to its inside.
(6) by arranging upper hold-down nut and lower hold-down nut can be reinforced right crane span structure and left crane span structure.

Embodiment
For making the object of the application, technical scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.
In the following description, quoting of " embodiment ", " embodiment ", " example ", " example " etc. is shown that the embodiment of so description or example can comprise special characteristic, structure, characteristic, character, element or limit, but not each embodiment or example must comprise special characteristic, structure, characteristic, character, element or limit.In addition, reuse phrase " embodiment according to the application " although be likely refer to identical embodiment, and not necessarily refers to identical embodiment.
For the sake of simplicity, eliminate in below describing and well known to a person skilled in the art some technical characteristic.
According to an embodiment of the application, provide a kind of reinforcement electric cable crane span structure, as shown in Figure 1, the left crane span structure 16 comprising right crane span structure 4 and be connected with right crane span structure 4; Be provided with upper mounted plate 13 and bottom plate 8 in cavity between left crane span structure 16 and right crane span structure 4, upper mounted plate 13 is connected by demarcation strip 17 with bottom plate 8, demarcation strip 17 is provided with hollow peg 18; Right crane span structure 4 inside is provided with for passive right cross spud pile 5 and the right ventilation link 6 playing permeation functions, the inner face of right crane span structure 4 is provided with right hook 7, the top of right crane span structure 4 is provided with upper right fixed projection 2, and the bottom of right crane span structure 4 is provided with bottom right fixed projection 10; Left crane span structure 16 inside is provided with for passive left cross spud pile 15 and the left ventilation link 14 playing permeation functions, the inner face of left crane span structure 16 is provided with left hook 12, the top of left crane span structure 16 is provided with upper left fixed projection 1, and the bottom of left crane span structure 16 is provided with lower-left fixed projection 11; The lateral wall of right crane span structure 4 is made up of eight right crane span structure hollow tubes 20, be connected by right ventilation link 6 between right crane span structure hollow tube 20, the lateral wall of left crane span structure 16 is made up of eight left crane span structure hollow tubes 19, is connected between left crane span structure hollow tube 19 by left ventilation link 14; Pressure tester is provided with in the cavity that right crane span structure and left crane span structure are formed.
According to an embodiment of the application, the lower-left fixed projection 11 of this reinforcement electric cable crane span structure and bottom right fixed projection 10 are fixed by lower hold-down nut 9, and upper left fixed projection 1 and upper right fixed projection 2 are fixed by upper hold-down nut 3.
This reinforcement electric cable crane span structure can solve existing reinforcement electric cable crane span structure well there is structural unstable problem by arranging right cross spud pile 5 and left cross spud pile 15 in use; The extruding that also can prevent between cable to the suspension effect that is separated of cable not only can be played by arranging right hook 7 and left hook 12; Not only can reinforce reinforcement electric cable crane span structure internal structure further while not blocking the circulation of this reinforcement electric cable crane span structure inner air by arranging demarcation strip 17 and hollow peg 18, and the effect of cable suspension can be played; Achieving the detachable structure of this reinforcement electric cable crane span structure by arranging right crane span structure 4 and left crane span structure 16, facilitating and inspection and maintenance is carried out to its inside; By arranging upper hold-down nut 3 and lower hold-down nut 9 can be reinforced right crane span structure 4 and left crane span structure 16.
The above embodiment only represents several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to scope.Therefore protection scope of the present invention should be as the criterion with described claim.
