1. the utility model is beneficial to the placement and checking of the bridge frame type article above the wall, enhances the stability and greatly improves the construction efficiency and quality;

2. the utility model can not damage the bridge frame or the peripheral installed equipment, avoid influencing other construction results, and increase unnecessary compensation;

3. the utility model has simple manufacture, convenient material drawing, convenient carrying by one person and ensured safety;

4. the utility model discloses can have the direct repacking of traditional ladder, reduce the efficiency of time and cost, easily promote.

5. The utility model discloses it is all more convenient to assemble and dismantle, circulated use, economic environmental protection, and it can assemble the back and go the scene, also can arrive narrow space scene earlier and assemble again, and the practicality is strong.

Drawings

Other objects and results of the invention will be more apparent and readily appreciated by reference to the following description taken in conjunction with the accompanying drawings, and as the invention is more fully understood. In the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The same reference numbers in all figures indicate similar or corresponding features or functions.

Detailed Description

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a portable crane span structure climbing ladder, including ladder body 1, support frame 2 and anti-drop support 3. The ladder body 1 can be made of leftover materials on a construction site, and the specific manufacturing method is that two long steel pipes are used as edges, and a plurality of parallel transverse pipes are welded between the two long steel pipes to manufacture the ladder body 1. In order to enhance the stability of the ladder body 1, the ladder body 1 can be made into a splayed ladder. The support frame 2 is arranged on the upper part of the ladder body 1, in this embodiment, the support frame 2 can be made of two steel pipes parallel to each other, and one steel pipe is correspondingly fixedly connected with one side of the ladder body. For the convenience of climbing, the included angle between the support frame 2 and the ladder body 1 is set to be 105 degrees. In addition, in order to make the connection between the ladder body 1 and the support frame 2 more firm, the support frame 2 is connected with the ladder body 1 through the connecting plate 4, in this embodiment, the connecting plate 4, one side of the ladder body 1 and one steel pipe on the support frame 2 are connected to form an obtuse triangle.

The anti-drop support 3 is fixed at the terminal side of support frame 2 keeping away from ladder body 1, and anti-drop support 3 extends towards the planar top in support frame 2 place, conveniently places or examines the cable like this. In order to ensure that the climbing ladder is safer when in use, the support frame 2 needs to be parallel to the horizontal plane, and the anti-falling support 3 is arranged perpendicular to the support frame 2, so that the anti-falling support 3 can be tightly abutted against the wall surface when in use, and the safety when in use is improved. The anti-drop support 3 is the polygon that is formed by many steel pipe welding, thereby polygonal setting can make anti-drop support 3 support the area of contact that has greatly increased its with the wall when leaning on with the wall and prevent to empty the drop. Among them, the falling off preventive bracket 3 is preferably formed in a trapezoidal shape because it is formed in a trapezoidal shape to prevent it from falling down to the left and right sides when in use.

In addition, in order to facilitate the disassembly and assembly, the connection part of the ladder body 1 and the support frame 2, the connection part of the support frame 2 and the anti-falling support frame 3 and the connection part of the connecting plate 4 and the ladder body 1 and the support frame 2 are perforated, and the components are connected by bolts and nuts during the assembly, so that the four components can be installed in advance, and the assembly can be carried out on site conveniently and quickly. After the use, also convenient to detach, reuse nature is strong.

Use the utility model discloses a crane span structure climbing ladder, can make ladder body 1, support frame 2, anti-drop module 3 and connecting plate 4 with leftover bits earlier on the scene as required, then punch the hole in two liang of part junctions, the equipment is connected with each part to reuse bolt and nut. After assembling, place the climbing ladder in the place that needs the inspection cable under the crane span structure, wherein anti-drop support 3 closely laminates with the wall, and the workman climbs from ladder body 1 and goes the operation, and the cable can be placed on support frame 2 between ladder body 1 and anti-drop support 3, the utility model discloses can not damage the crane span structure or the peripheral equipment instrument of having installed, the security is high.

The portable bridge climbing ladder according to the present invention is described above by way of example with reference to the accompanying drawings. However, it should be understood by those skilled in the art that various modifications can be made to the portable bridge climbing ladder provided by the present invention without departing from the scope of the present invention. Therefore, the scope of the present invention should be determined by the content of the appended claims.
