Technical field
The utility model relates to a kind of single-column overhaul of the equipments pole ladder, especially is applicable to the inspection platform operation ladder of ascending a height of transformer station's single-column equipment.
Background technology
The power transformation station equipment mostly is open side type framework layout, and especially the mutual inductor kind equipment all is erected at open side type cement electric pole top, and there is following difficult point in its service work: 1, and it is little to be subjected to equipment to influence working space.2, the bus that had by method of operation restriction can not have a power failure.3, if the danger of using large-scale inspection platform or bucket arm vehicle to have eminence to get an electric shock.The defective that existing novel ladder ladder exists is: volume is big, installing/dismounting carrying inconvenience, and work high above the ground can not guarantee operating personnel's safety.
The utility model content
It is little that technical problem to be solved in the utility model provides a kind of volume, installs firmly, and the dismounting convenient in carrying is protected the single-column overhaul of the equipments pole ladder of clear work high above the ground safety.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of single-column overhaul of the equipments pole ladder is characterized in that: comprise extension ladder and basis ladder; The bottom of described extension ladder is connected by attachment screw with the top of basis ladder; Described extension ladder comprises guard ring, following guard ring, platform, guide rail and tilted supporter; The last guard ring of described extension ladder and following guard ring are " U " type circle, and its two ends portion is hinged with two columns of extension ladder respectively; Described platform is a rectangular flat, and the transverse axis that an one end face connects and two columns of extension ladder are hinged; Described guide rail is a pair of platform bottom surface boxlike guide rail that Open Side Down that is positioned at; Described tilted supporter is " H " type support that the bottom is provided with crossbeam, and described crossbeam is hinged with two columns of extension ladder respectively; Described basic ladder comprises flexible collar and following flexible collar; The described flexible collar that goes up is " U " type circle with following flexible collar, and the double head of one end is connected on two root posts of basis ladder with screw, and it establishes the through hole that fastening bolt is housed on the position between basic ladder and the dome.
At further improvement of the utility model be: described basic ladder also comprises support bar; Described post upper is supported on the bottom surface of platform, and its lower end is stuck on the fastening bolt of flexible collar.
Adopt the beneficial effect that technique scheme produced to be: the disclosed a kind of single-column overhaul of the equipments pole ladder of the utility model, because two flexible collar of basis ladder are held tightly the basic electric pole of whole pole ladder and equipment fixing, operating personnel stand in two guard ring protections on the platform, ensured work high above the ground safety; Avoided adjacent spaces equipment or bus to have a power failure; Improved power supply reliability.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a front view of the present utility model;
Fig. 2 be Fig. 1 left view.
Shown in Fig. 1 and Fig. 2: insulation sleeve on 1, guard ring on 2,3 times guard rings, 4 extension ladders, 5 attachment screws, 6 basis ladders, flexible collar on 7,8 times flexible collar, 9 times insulation sleeves, 10 platforms, 11 guide rails, 12 tilted supporters, 13 support bars, 14 fastening bolts, 15 equipment electric poles.
The specific embodiment
By embodiment illustrated in figures 1 and 2 as can be known, it draws together extension ladder 4 and basis ladder 6; The bottom of described extension ladder 4 is connected by attachment screw 5 with the top of basis ladder 6; Described extension ladder 4 comprises guard ring 2, following guard ring 3, platform 10, guide rail 11 and tilted supporter 12; The last guard ring 2 and the following guard ring 3 of described extension ladder 4 are " U " type circle, and its two ends portion is hinged with two columns of extension ladder 4 respectively; Described platform 10 is a rectangular flat, and the transverse axis that an one end face connects and two columns of extension ladder 4 are hinged; Described guide rail 11 is a pair of platform bottom surface boxlike guide rail that Open Side Down that is positioned at; Described tilted supporter 12 is provided with " H " type support of crossbeam for the bottom, and described crossbeam is hinged with two columns of extension ladder 4 respectively; Described basis ladder 6 comprises flexible collar 7 and following flexible collar; The described flexible collar 7 that goes up is " U " type circle with following flexible collar 8, the double head of one end is connected on two root posts of basis ladder 6 with screw, its circular arc inner face is enclosed within on the equipment electric pole 15, and it establishes the through hole that fastening bolt 14 is housed on the position between basis ladder 6 and the dome.Described basis ladder 6 also comprises support bar 13; Described support bar 13 upper ends are supported on the bottom surface of platform 10, and its lower end is stuck on the fastening bolt 14 of flexible collar 7.Because there is last rubber sheath 1 on extension ladder 4 tops, following rubber sheath 9 is arranged at terraced 6 bottoms, basis, has guaranteed the insulating properties of whole pole ladder.
