Detailed Description
When a gully spanning 1.5m and a steep slope with the vertical height of 1.3m are needed, arch bridge type, nail climbing type and long ladder type auxiliary tools can be selected. As shown in figure 1, the arch bridge type has the advantages that due to the self structure, the gravity center is difficult to install due to the shape problem, the arch bridge type is high in bearing capacity and can bear heavier body types, and the stability is highest due to the structural characteristics of the arch bridge design, so that the stability requirement is met. As shown in fig. 2, the similar climbing nail type structure is simple, but climbing nails are more, operating personnel are easy to install, but consuming time is long, the similar climbing nail type bearing is lighter, because structural problems are easy to break, and because only a single main material is available, the stability is poor, climbing nails are easy to turn over and follow the head, and people are needed to support the climbing nail type bearing. As shown in figure 3, the long ladder type structure is simple, the operating personnel can be easily installed, the long ladder type bearing is moderate, the requirement of the weight of most of the working personnel can be met, the stability is high, and the requirement of the stability is met.
The utility model provides a line patrols appurtenance, this appurtenance includes tip 1, intermediate part 2 and connecting portion 3, and tip 1, intermediate part 2 and connecting portion 3 are hollow, and tip 1 and intermediate part 2 link together through connecting portion 3, and tip 1 and intermediate part 2 all include two the same poles 6 of length and the crossbeam 5 of connecting two poles 6, pole both ends and connecting portion both ends have buckle or hinge, buckle or hinge are used for being connected the one end of tip and the one end of connecting portion to and be connected the other end and the intermediate part of connecting portion, through the buckle can be folded up this appurtenance's tip and intermediate part in order to reduce this appurtenance's length.
In one embodiment, the clasp is an umbrella stem clasp, as shown in FIG. 4, of 1.5m overall.
In one embodiment, the catch is a shaft-driven catch, as shown in FIGS. 5-7, of 1.5m overall.
As shown in fig. 8, the connecting portion 3 is oval and has a central slide.
Through 200 times of drawing experiment statistics, the number of required sections is less in a mode of axially moving the buckle, so that the smoothness in drawing is more easily ensured; the umbrella handle has more buckle joints and is easy to be blocked. As shown in fig. 4-5, the bending degree shows that the umbrella handle buckle is too large due to the large number of joints, so that the structural stability is weak and the umbrella handle buckle is easy to damage; the shaft-driven buckle has almost no bending angle, and the connection firmness and stability are stronger than those of an umbrella handle. The umbrella is provided with braces, the total retracting length of the umbrella handle buckle is about 0.75m, and the total retracting length of the shaft-driven buckle is 0.5 m; the shaft-driven buckle type is shorter, is more suitable for back braces and is more convenient to carry.
In one embodiment, the auxiliary tool comprises two end portions and an intermediate portion.
In one embodiment, the end portions are identical in construction to the intermediate portion.
In one embodiment, the end bars are welded to the cross-beam to form an i-shape.
In one embodiment, the shaft-driven snap is fixed by a screw.
In one embodiment, the end, intermediate and connecting portions of the auxiliary tool may be made of iron, aluminum alloy or carbon fiber material. The material part mainly considers self weight, bearing capacity, bending strength and self performance. Among conventional materials, iron is widely used for ship manufacturing, and its strength is recognized as 7.85g/cm density3The bearing capacity is 1000kg, the bending is hardly realized, and the corrosion is easy; the aluminum alloy is taken as a representative of weight-reducing material, the material is light, the material is firm and reliable, and the density is 2.7g/cm3The bearing capacity is 100kg, the steel plate can be bent, but cannot be recovered due to overlarge angle, and the bearing capacity is poor; carbon fibres are outstanding as emerging materials, their lighter weight and sufficient strength being favored by more and more mechanical products, with a density of 1.6g/cm3The bearing capacity is 300kg, the bending degree is large, and the material is stable. In conclusion, the iron material has excellent bearing capacity, but has high density and maximum weight with the same volume, is not suitable for single-soldier operation, and is easy to corrode and not suitable for field operation; although the aluminum alloy material is light and easy to be metalworked, the aluminum alloy material has poor bearing capacity and does not meet the target value; carbon fibers are preferred because they are expensive, but they meet the target requirements for each index.
The carbon fiber material, 6 carbon fiber tubes with the length of 1m and 3 carbon fiber plates with the length of 30cm multiplied by 40cm can bear more than 300 kg. And (5) manufacturing a model, and bearing the weight of 240kg after processing. The distance between the axes of the buckles at the two ends of the connecting part 3 is 15cm, the diameter of the buckles is 2cm, the diameter of the carbon fiber tube is 5cm, and the length of the rod is 0.5 m. The average disassembly and assembly time is about 3 minutes, and the phenomenon of jamming does not occur.
The utility model provides a bridge ladder includes the body of rod and crossbeam the crossbeam with the body of rod is connected, the crossbeam accessible the body of rod with the connecting device of crossbeam rotates and fixes the solution when climbing high or crossing terrains such as ditch, the transport that uses traditional ladder is troublesome, carry inconvenient scheduling problem. Can span a gully of 1.5m and a steep slope with the vertical height of 1.3m, is suitable for single-person operation, and has the advantages of light installation, reliable and firm structure and convenient carrying.
The above-mentioned embodiments are only used for explaining the present invention, wherein the structure, connection mode, etc. of each component can be changed, and all the equivalent transformation and improvement performed on the basis of the technical solution of the present invention should not be excluded from the protection scope of the present invention.
