Abstract
The utility model discloses an electric power overhaul ladder, which comprises a ladder frame, wherein a fixing device is arranged on the upper end of the ladder frame and is formed by a fixing clamp and a connecting clamp; the fixing clamp is formed by hinging a semi-circular fixed half clamp and a movable half clamp; a clamp spring is arranged between the two half clamps; the connecting clamp and the fixed half clamp are formed through metal casting; a cross section of a connecting part between the connecting clamp and the ladder frame can be determined according to a shape of the upper end of the ladder frame; a stay wire is arranged on the fixed half clamp; one end of the stay wire is connected with the movable half clamp; and anti-skidding pads are respectively arranged in the fixed half clamp and the movable half clamp. According to the utility model, since the fixing device is arranged on the ladder, when channel steel or round steel is lapped on the ladder, the fixing device can be buckled on the channel steel or the round steel; the anti-skidding pads are arranged on the fixing clamp, so that the ladder cannot skid leftwards or rightwards or fall down when being used, and is safe and reliable, the safety of overhaul personnel can be ensured, and the working efficiency of electric power overhaul is improved.
Description
Technical field
The utility model relates to a kind of ladder, particularly a kind of electric power overhaul ladder that increases the fixing fastness of ladder, guarantees maintainer's safety.
Background technology
At present, the mode of when maintenance eminence equipment, generally all ascending a height with ladder is overhauled, and the reliability that when ascending a height maintenance, guarantees ladder is the necessary condition that guarantees maintainer's safety.But the no fastening devices in traditional ladder commonly used upper end has only smooth equipment surface, and the upper end is prone to slide or fall ladder during use, causes the dangerous of ascend operation, second need the special messenger during ascend operation holds up and keeps, and it is many to take the staff, and efficient is low.
The utility model content
To the weak point that prior art exists, the utility model in provide a kind of can the fixing electric power overhaul ladder in upper end, prevent that ladder from sliding and swing, guarantee maintainer's safety, improve the operating efficiency of electric power overhaul.
To achieve these goals, the technical scheme of the utility model is: a kind of electric power overhaul ladder comprises ladder; Described ladder upper end is provided with fastening devices; Described fastening devices is made up of fixed card, Connection Card, and described fixed card is partly blocked dumpling by semicircular fixing half card and activity and connect and form, and two and half are provided with jump ring between blocking; Described Connection Card is the die cast metal moulding with fixing half card, and its cross section with ladder institute junction can be definite according to the upper end shape of ladder.
Further, on described fixing half card backguy is set, one of described backguy and movable half blocks and is connected.
Further, in described fixing half card and movable half card slipmat is set.
The beneficial effect of the utility model is: after a fastening devices is set on the ladder; When using ladder to cost channel-section steel or round steel, fastening devices can be buckled on channel-section steel or the round steel, and slipmat is installed on the fixed card; Guarantee when using ladder, to slide into about not meeting or fall terraced; Safe and reliable, can guarantee maintainer's safety, and improve the efficient of electric power overhaul work.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is further described.
As shown in Figure 1, the electric power overhaul ladder of the utility model comprises ladder 1; Described ladder 1 upper end is provided with fastening devices, and described fastening devices is made up of fixed card, Connection Card 2, and described fixed card fixing partly blocked 3 and partly blocked 4 dumplings with activity and connect and form by semicircular; 5 connect axle for dumpling; Fixing partly block 3 and activity jump ring is set between partly blocking 4, described Connection Card 2 partly blocks 3 and is the die cast metal moulding with fixing, its cross section with 1 junction of ladder can be definite according to the upper end shape of ladder 1.Described fixing partly the card is provided with backguy 7 on 3,7 one of described backguys partly block 4 with activity and are connected.Describedly fixing partly block 3 and partly block with activity slipmat 6 is set in 4.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical scheme of the utility model all falls within the protection domain of the utility model.
