Background technology
In aerial high-voltage power transmission line, composite insulator one of the member that is absolutely necessary.Good because of its hydrophobicity, the anti-pollution flashover ability of silicon rubber compound insulator is strong, is applied to pollute comparatively serious area in a large number.
Exactly because the installation of composite insulator, in maintenance or inspection transmission line of electricity process, the way that adopts is to climb up and down along composite insulator usually, steps on because operator's climbing is pedaled, and insulator causes damage easily, influences the safe operation of circuit; Particularly silicon rubber compound insulator owing to self material characteristic, is very easy to cause damage, must change composite insulator, cost of idleness; If trampled the untimely replacing of bad composite insulator, can be had a strong impact on the safe operation of transmission line of electricity.
Therefore, need a kind of special climbing instrument, in maintenance or inspection transmission line of electricity process, avoid trampling and climbing, the damage that the artificial climbing of elimination causes insulator, saving cost when guaranteeing the transmission line of electricity safe operation composite insulator.
The utility model content
In view of this, the purpose of this utility model provides a kind of portable composite insulator cat ladder, in maintenance or inspection transmission line of electricity process, avoid trampling and climbing to composite insulator, eliminate the damage that artificial climbing causes insulator, guarantee the transmission line of electricity safe operation and save cost, simultaneously, volume is little, in light weight, easy to carry, be applicable to that transmission line of electricity uses.
Portable composite insulator cat ladder of the present utility model comprises fastening devices, following fastening devices, flexible terraced body and ladder step, and described ladder goes on foot at least one and is fixedly installed on one's body the flexible ladder, and the distance between the adjacent terraced step satisfies the operator and climbs demand; Last fastening devices and following fastening devices are fixedly installed on flexible terraced body two ends respectively, and can be fixedly connected with respect to iron tower respectively.
Further, also comprise cat ladder length adjusting device, described adjusting device adopts the structure of take-up pincers, and the take-up pincers are arranged on the top of flexible terraced body or/and the bottom;
Further, the described ladder step is adopted circulus, and the ring-type size is not less than operator's pin lateral dimension; Flexible terraced status section was connected between the adjacent ring-type ladder step;
Further, described flexible ladder is as the establishment band;
Further, described upward fastening devices and/or following fastening devices are hook.
The beneficial effects of the utility model are: portable composite insulator cat ladder of the present utility model, adopt the flexible terraced body and the structure in ladder step, cooperation is with fastening devices up and down, in maintenance or check and to avoid in the transmission line of electricity process damage that artificial climbing causes insulator is eliminated in the trampling and climbing of composite insulator, guarantee that the transmission line of electricity safe operation also saves cost, the utility model is simple in structure, easy to assembly, can single independent complete operation, saved the labour; Simultaneously, volume is little, in light weight, can directly put into kit after folding, and is very convenient to carry, particularly in mountain route and ungetable job site, shown special advantages; Owing to use flexible terraced body, be convenient to stored collapsed and carry, can increase work efficiency greatly; Take-up pincers are set, and the spacing during according to operation is tightened up or is loosened flexible terraced body, can effectively fix and the terraced body of stretching flexibility assurance operator's safety; Flexible terraced body adopts the establishment band, the tensile strength height, and resistance to torsion is good, increases safety.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation front view of the present utility model;
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
Fig. 1 is a structural representation front view of the present utility model, and Fig. 2 is the lateral view of Fig. 1, looks as figure:
The portable composite insulator cat ladder of present embodiment, the flexible terraced body 4 and the aluminium alloys ladder step 3 that comprise fixed hook 1, fixed hook 11, the making of establishment band down, the height that the ladder step 3 climbs as required is a plurality of uniform being fixedly installed on one's body the flexible ladder, satisfy the operator between the adjacent ladder step 3 and climb demand, the ladder step 3 is adopted circulus, and ring-type internal orifice size is not less than operator's pin lateral dimension; Flexible terraced body 4 segmentations were connected between the adjacent ring-type ladder step 3; Last fastening devices 1 and following fastening devices 11 are fixedly installed on flexible terraced body 4 two ends respectively, and can fixedly connected with the insulator string fixed mount with the iron tower cross-arm respectively; Last fixed hook 1 and following fixed hook 11 adopt aluminum alloy material.
Also comprise cat ladder length adjusting device 2, described adjusting device adopts the take-up wrench structure, and the take-up pincers are arranged on the upper and lower of flexible terraced body 4;
