Abstract

The utility model relates to a grid crane span structure which comprises a plurality of warp brackets and a plurality of weft brackets. The warp and weft brackets are overlapped like grids. Both sides of the weft brackets incline outward, and wavy side wire brackets are arranged at the top ends on both sides of the weft brackets. The grid crane span structure provided by the utility model has the beneficial effects that the grid crane span structures in same specifications can be directly sleeved, so that the transporting and storage space is saved; and the wavy side wire brackets are arranged at the top ends on both sides of the weft brackets, so that mechanical injury to operators by the weft brackets is avoided. The grid crane span structure is more convenient to use.

Description

A kind of grid crane span structure

Technical field

The utility model relates to a kind of grid crane span structure.

Background technique

When cable, communication optical cable or other fine long class tubing are laid, usually all can use the grid crane span structure to support, cover and protect this class device.General grid crane span structure is exactly the parallel support and forms through the simple overlap joint of line bracket at present, and two large shortcomings are arranged during use, and the one, parallel support both sides are overhanging, easily scratch operator in loading and unloading, transportation, installation, maintenance process; The 2nd, because the parallel support is all made according to U-shaped, when transportation, what single grid crane span structure can not be complete is inserted in another, need take large quantity space during transportation, if be inserted in by force, not only wastes time and energy during taking-up, also easily causes the distortion of network crane span structure.

The model utility content

The purpose of this utility model is to provide a kind of grid crane span structure, to overcome present prior art above shortcomings.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of grid crane span structure comprises somely through line bracket and some U-shaped parallel supports, describedly is overlapped to form latticedly through line bracket and parallel support, and the both sides of described parallel support tilt laterally, and top, described parallel support both sides is provided with waveform limit silk support.

Further, described parallel support be connected with the Bian Si support welding through line bracket.

The beneficial effects of the utility model are: a kind of grid crane span structure that the utility model provides, and the grid crane span structure of same size can directly be set with, and has saved transportation and storage area; Waveform limit silk support is positioned at the parallel cantilever tip, has avoided the mechanical deterioration of parallel support to operator, uses also convenient.

Description of drawings

The below is described in further detail the utility model with reference to the accompanying drawings.

Fig. 1 is the structural representation of the described grid crane span structure of the utility model embodiment;

Fig. 2 is the partial enlarged drawing at I place in Fig. 1.

In figure:

1, through line bracket; 2, parallel support; 3, limit silk support.

Embodiment

As shown in Fig. 1-2, the described a kind of grid crane span structure of the utility model embodiment, comprise some through line bracket 1 and some U-shaped parallel supports 2, it is characterized in that: describedly be overlapped to form latticed through line bracket 1 and parallel support 2, the both sides of described parallel support 2 tilt laterally, and described parallel support 2 tops, both sides are provided with waveform limit silk support 3.Described parallel support 2 be welded to connect through line bracket 1 and Bian Si support 3.

The utility model provides grid crane span structure limit silk support 3 anti-oarsman's structures can effectively prevent from loading and unloading, in the transportation, installation, maintenance process to operator's mechanical deterioration; Limit silk support 3 changes to waveform by existing lineal shape, installs to take to become more convenient, reasonable.The arrangement mode through line bracket 1 of grid crane span structure bottom and sidepiece: the existing crane span structure of change bottom and sidepiece through line bracket 1 arrangement mode, the grid crane span structure that reaches same size can be in the situation that do not produce any deformation damage and other any damages to another, be placed in another fully suitably, thereby reduce storage, transport space.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technological scheme, within all dropping on protection domain of the present utility model.
