Description

Technical Field

[0001] The utility model belongs to the technical field of large bending moment electric poles, in particular to a circular climbing nail for large bending moment electric poles. Background Art

[0002] Large bending moment poles are a special type of cement poles, usually made of steel hoops, steel bars and concrete, with excellent toughness and crack resistance. Large bending moment cement poles are often used at the terminals and corners of the entire transmission line. Their advantage is that they do not require guy wires, which greatly saves floor space, so they are widely used in the construction of power systems.

[0003] The tail diameter of large bending moment cement poles varies from 230 to 430 mm depending on the force requirements. When it is necessary to work on the pole, considering that the starting diameter of this type of pole is too large, it is inconvenient to climb up with foot buckles and stepping plates, and climbing nails or ladders are more often used for equal height operations.

[0004] Climbing nails and ladders are faster and more convenient than foot buckles and pedals in the process of climbing poles. However, it is very uncomfortable to step on a round steel with a diameter of 16mm for a long time when working on the pole. Especially during the work, the pain is strong and the feet need to change positions constantly to bear it. In addition, the friction coefficient on this single round steel is too high and it is easy to slip and step on air. In addition, if working in the middle of the pole, due to the large diameter of the pole, the waist belt of the safety belt is not long enough, and the operator is almost tied to the pole and cannot stretch to work, etc., which poses a great safety hazard.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the relevant technical solutions. Obviously, the described embodiments are only part of the embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1: Combination Figure 1 and Figure 2It can be seen that the large bending moment pole circular climbing nail disclosed in this embodiment includes a limiting plate 2 and a limiting rod 1.

[0025] The limiting plate 2 is a thin arc-shaped plate, and a strong glue is provided on the inner side of the arc of the limiting plate, which is used to stick the limiting plate to the large bending moment rod.

[0026] The limit rod 1 is a circular steel cylindrical long rod. One end of the limit rod is longer than the other end, and the end of the long end is a threaded section. The short end of the limit rod is welded and fixed to the arc-shaped outer side of the limit plate, and the long end of the limit rod passes through the limit plate from the outside to the inside. Two locking nuts 3 are arranged on the threaded section of the limit rod on the arc-shaped outer side of the limit plate.

[0027] The circular bending section of the limit rod is tilted upward to prevent the operator from sliding out from the outside after stepping on the climbing nail.

[0028] The surfaces of the long end and the short end of the limiting rod are both provided with corrugations to increase the friction between the foot and the climbing nail.

[0029] When installing the circular climbing nail, first reserve a climbing nail installation threaded hole on the large bending moment rod, rotate the long end of the limit rod and insert it into the reserved hole for limiting, rotate until the limit plate is close to the large bending moment rod, and then stick the limit plate to the large bending moment rod with strong glue; finally, tighten the nut on the limit rod toward the limit plate, and press the limit plate tightly against the large bending moment rod to ensure the stability of the circular climbing nail.

[0030] The advantages of using this paper-shaped climbing nail are:

[0031] 1. When the operator uses this circular climbing nail, his feet are on the circular round steel, which has better force and is not easy to lose balance; at the same time, it is more comfortable and is conducive to long-term operation for professionals.

[0032] 2. The operator's safety belt can be tied to the limit rod, and the circular design prevents it from sliding out, which is safer.

[0033] 3. A nut is set on the limit rod to tighten the limit plate to the large bending moment rod, which strengthens the overall structural strength of the climbing nail and ensures good stability during use.

[0034] Embodiment 2: Combination Figure 3 and Figure 4 It can be seen that the large bending moment pole circular climbing nail disclosed in this embodiment is different from that in the first embodiment in that:

[0035] No limiting plate is provided, and the short end of the limiting rod is directly welded and fixed to the middle section of the long end.

[0036] When installing the climbing nail of this embodiment, insert the long end of the limit rod into the reserved hole on the large bending moment rod, and then tighten the nut on the limit rod toward the large bending moment rod. At this time, the threaded section of the nut and the limit rod are subjected to opposing forces, firmly fixing the climbing nail on the large bending moment rod.

[0037] Compared with the first embodiment, the present embodiment has poorer stability, but improves the convenience of installation, and can be used when the circumference of the large bending moment rod is small and it is not convenient to install the limit plate.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although detailed descriptions are made with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
