Abstract
The utility model discloses a novel ladder type crane span structure which comprises ladder sides and cross arms. Each ladder side is provided with a plurality of sets of punching holes, and the punching holes comprise forward-direction punching holes and reverse-direction punching holes all of which are formed at intervals. The forward-direction punching holes sequentially comprise a longitudinal long circular hole, two triangular holes opposite in apex angle direction degree and a transverse long circular hole; the reverse-direction punching holes sequentially comprise a transverse long circular hole, two triangular holes opposite in apex angle and a longitudinal long circular hole; the apex angle of each triangular hole intersects with one of the circular holes. By means of the punching holes formed in the ladder sides, the shape of the ladder type crane span structure can be changed by conducting simple operation conveniently, requirements for local environment adjustment are met, using amount of curve through devices is reduced, engineering cost is saved, and construction efficiency is greatly improved. The novel ladder type crane span structure is longitudinally symmetrical, can be installed without recognizing the direction, is flexible and convenient to use and can meet the requirements of complex construction environments, and the application range of the ladder type crane span structure is significantly enlarged.
Description
Technical field
The utility model belongs to field of machining, especially relates to a kind of novel ladder-type bridge frame.
Background technique
In work progress, traditional ladder type ladder, when turning to, often need a large amount of curved logical series products to meet on-the-spot trend, and the work efficiency of curved logical series products is low, use very flexible, and cost is high.When construction, the curved logical series products of a large amount of uses, can have a strong impact on Construction of Engineering Projects progress, improves construction cost, causes the wasting of resources.
Model utility content
The purpose of this utility model is to provide a kind of novel ladder-type bridge frame, improves the flexibility that crane span structure is used, and meets the needs of different construction environments.
For realizing the problems referred to above, the technical solution adopted in the utility model is: novel ladder-type bridge frame, comprises terraced limit and cross-arm; Described terraced limit is provided with some groups of punchings, and these some groups of punchings are arranged and formed by forward punching and reverse punching interval; Forward punching comprises longitudinal slotted hole, two tri-angle-holed, horizontal slotted holes that drift angle is contrary successively; Oppositely punching comprises horizontal slotted hole, two tri-angle-holed and longitudinal slotted holes that drift angle is contrary successively; Described tri-angle-holed drift angle and a circular hole intersect.
Further, the cross section of described cross-arm is Z-shaped structure, has 4 place's bending edges, and outside crimp is towards side-lower.
Further, on the upper and lower surfaces of the Z-shaped structure of described cross-arm, be equipped with some transversely arranged punchings.
Utilize the punching on terraced limit, carry out easy operation and just can change the shape of ladder-type bridge frame, meet the needs that local environment is adjusted, reduced curved logical usage quantity, saved engineering cost, improved greatly efficiency of construction.And the ladder-type bridge frame that this programme forms is symmetrical up and down, without identification direction, just can install, easy to use and flexible, can meet the demand of complicated construction environment, has improved significantly the using scope of ladder.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As depicted in figs. 1 and 2, novel ladder-type bridge frame, comprises terraced limit 1 and cross-arm 2, and the two ends of cross-arm 2 are welded on terraced limit 1.The cross section of cross-arm 2 is Z-shaped structure, has 4 place's bending edges, can improve the bearing strength of cross-arm.The outside crimp of cross-arm 2, towards side-lower, has solved the hidden danger that cable is scratched when laying.For ease of binding cable, on the upper and lower surfaces of the Z-shaped structure of cross-arm 2, be equipped with some transversely arranged punchings, form laterally zygomorphic structure.Ladder limit 1 is provided with some groups of punchings, and these some groups of punchings are arranged and formed by forward punching and reverse punching interval; Forward punching comprises tri-angle-holed 4, the horizontal slotted hole 5 that longitudinal slotted hole 3, two drift angles are contrary successively; Oppositely punching comprises tri-angle-holed 4 and the longitudinal slotted hole 3 that horizontal slotted hole 5, two drift angles are contrary successively.The punching arrangement of ladder on limit and the Z-shaped structure of cross-arm, symmetrical up and down, appearance looks elegant, from heavy and light, the upper and lower surface of crane span structure all can attached cable, during construction, without direction, recognizes, has improved the flexibility of construction.
As shown in Figure 3 and Figure 4, when the horizontal cross-layer of needs transformation ladder, only need delthyrium 41 on slave ladder limit and 42 dotted line place to cut, and then carry out bending welding, can on-the-spot complete the cross-layer structure transformation of ladder.
As Fig. 3 and and Fig. 5 as shown in, when needs Vertical direction changes ladder and moves towards, only need delthyrium 41 on slave ladder limit and 43 dotted line place to cut, and then carry out bending welding, can on-the-spot complete the structure of modification of the Vertical direction of ladder.
At crane span structure, constructing in layer, is avoiding barrier, can as required novel ladder-type bridge frame be out of shape arbitrarily.As shown in Figure 6 and Figure 7, deformation process is in the horizontal direction: first that novel ladder-type bridge frame is edge-on, and then longitudinal slotted hole 3 on a terraced limit is alignd and fixed with simple platform 6, Yi Bian firmly pressing down in addition, can complete the making of skew ladder.General manpower can complete, and without professional tool, offset distance can be controlled according to simple platform height.
In addition, the transformations such as novel ladder-type bridge frame frame also can complete that level curves etc., there is the features such as simple to operate, molded appearance is regular together, efficiency is high, practical, can greatly improve crane span structure installation efficiency at the scene, to the part adjustment in installation process, all can easily complete.
