The utility model content
For a plurality of problems that exist in above prior art, the utility model provides a kind of multipurpose maintenance ladder that busbar overhaul is ascended a height and the bus-bar frame welding is ascended a height to be used that collects.
The utility model is achieved through the following technical solutions:
Multipurpose maintenance ladder comprises terraced body, and described terraced body is extension ladder, and its top is provided with hook, is hinged with fixed support with the terraced body upper end of bill homonymy, after fixed support launches with terraced body formation " people " font.
The terraced body top of described and bill homonymy is provided with for the hoop hand of partly encircling isometrical bar.
Described hoop hand two ends is connecting ring, is used in conjunction with the steel wire snap close.
The terraced body of described hook below is provided with the safety rope retainer ring.
Described fixed support lower end is provided with transverse support bar.
Both sides, described terraced body lower end are connected with fixed feet.
Described fixed feet is articulated in terraced body lower end side, and fixes by locking device.
Described locking device comprises the brace that is arranged on terraced body, and the Connection Block on fixed feet, is equipped with bolt hole on described brace and Connection Block, and a bolt passes the bolt hole of brace and Connection Block and can fix.
Described extension ladder is pulley-type, nested type or bail type.
The beneficial effects of the utility model are: busbar overhaul device therefor and the bus-bar frame welding device therefor of ascending a height of ascending a height is united two into one, guaranteeing greatly to have improved the coefficient of safety of equipment under the prerequisite of practicality, also reduced the difficulty of practical operation simultaneously.Equipment of the present utility model can be realized more reasonably utilizing in the newly-built and maintenance process of transformer station, increases work efficiency, and maintenance and the construction working that makes is more convenient, faster, safer.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is hoop hand portion structural representation;
Fig. 3 is fixed feet locking device structure schematic diagram.
In figure: 1 is terraced body; 2 are hook; 3 is fixed support; 4 is transverse support bar; 5 is the safety rope retainer ring; 6 are the hoop hand; 7 is connecting ring; 8 is the steel wire snap close; 9 is fixed feet; 10 is brace; 11 is Connection Block; 12 is the bolt hole of brace; 13 is the bolt hole of Connection Block; 14 is bolt.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The utility model provides a kind of multipurpose maintenance ladder, and what wherein terraced body 1 adopted is extension ladder, and quality is light, easy to carry, capable of expansion and contraction.During use, ladder is adjusted to ideal height; When not using, ladder is drawn in, its physical length can be reduced by at least over half, is convenient to transportation and deposits.Extension ladder can adopt multiple flexible form, as pulley-type, nested type or bail type.Compare and ascend a height with climbers, utilize ladder to ascend a height time saving and energy saving, effectively improved operating efficiency, also can strengthen the comfortableness of ascend operation simultaneously.
For reaching busbar overhaul device therefor and the bus-bar frame welding purpose that device therefor unites two into one of ascending a height of ascending a height, the utility model has increased following equipment on the basis of terraced body 1:
Be hinged with fixed support 3 with terraced body 1 upper end of hook 2 bill homonymy.After launching, fixed support 3 can form " people " font with terraced body 1.What utilize is the triangle stability principle herein, conveniently uses when busbar overhaul, and fixed support 3 can launch in the zone of action of semicircle, against living the fixed object such as cement pole.Fixed support 3 can be packed up when carrying out the bus-bar frame welding, utilize bracket lock that fixed support 3 is conquered and be close to terraced body 1.Stability when launching for improving fixed support 3, the utility model is provided with transverse support bar 4 in the lower end of fixed support 3.
Bus-bar frame is ascended a height when welding, terraced body 1 need to be fixed with isometrical bar, improving the stability of terraced body 1, and guarantee the fail safe that the electric welder operates.Therefore, the utility model is provided with for the hoop hand 6 of partly encircling isometrical bar on terraced body 1 top with hook 2 bill homonymy, and hoop hand 6 two ends are connecting ring 7, use with steel wire snap close 8 to be used in conjunction with.With after connecting ring 7 and 8 lockings of steel wire snap close, reached fixing to terraced body 1, prevent that terraced body 1 from arbitrarily sliding along isometrical bar.
For increasing the contact area on terraced body 1 and ground, improve terraced body 1 stability in use, the utility model also is hinged with fixed feet 9 in the two sides of terraced body 1 lower end, and fixes by locking device.Wherein locking device comprises the brace 10 that is arranged on terraced body 1, with the Connection Block 11 on fixed feet 9, be equipped with bolt hole 12 and 13 on brace 10 and Connection Block 11, one bolt 14 can pass the bolt hole 12 and 13 on brace 10 and Connection Block 11, and this moment, fixed feet 9 was in stable lock-out state.
In addition, for avoiding in maintenance during bus, the personal safety problem of bus because being subjected to bring after External Force Acting fracture suddenly, the utility model suggestion operations work needs to connect for anti-fall contour safety lock after reaching specified altitude assignment.
