Description

The electric power overhaul ladder
Technical field
The utility model relates to a kind of ladder, and relating in particular to increase the fixing fixing in ladder upper end, reduces swing, guarantees the electric power overhaul ladder of maintainer's safety.
Background technology
At present, the mode of generally all ascending a height with ladder when maintenance eminence equipment is overhauled, and the reliability that guarantees ladder when ascending a height maintenance is the necessary condition that guarantees the maintainer.But there is a following difficult problem in ladder commonly used at present: one, the ladder upper end just is placed on equipment surface and does not have fastening devices, because ladder is easy to slide or fall ladder in the upper end in use, the personal security of ascending a height coefficient is less; Need the special messenger to hold up when two, ascending a height and keep, dried same need of work personnel are more, and efficient is low.
The utility model content
In sum, in order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of ladder upper end can being fixedly secured, and prevents the ladder swing, guarantees the electric power overhaul ladder of maintainer's safety.
A kind of electric power overhaul ladder comprises ladder, and wherein, the ladder upper end is provided with fixture, and fixture is mainly by fixed card, and rotating shaft is arranged on the spring in the rotating shaft, and connecting rod consists of, and fixed card and connecting rod are hinged by rotating shaft.
Further, the fixed card inboard is semi-circular structure of being combined with square, and the connecting rod inboard is semi-circular structure, and is provided with slipmat in fixed card and connecting rod inboard.
Further, be equipped with retainer plate on fixed card and the connecting rod.
Further, also being provided with flexible rope on the fixture, flexible rope one end is connected with retainer plate on the fixed card.
Further, also be provided with shop bolt on the connecting rod.
The good effect of technical solutions of the utility model is:
The utility model is to have installed a fastening devices additional in original ladder upper end, make it can be when ladder is costed channel-section steel or round steel, fastening devices can be buckled on channel-section steel or the round steel, and on fastening devices and channel-section steel or round steel contact surface, slipmat is installed, add the former slipmat that carries of ladder leg, guaranteed when using ladder without special messenger's staircase situation under, ladder no longer horizontally slips or falls ladder, this installs the also available screw connection of available rivet etc., thereby reaches convenient fixing purpose; Bolt connects easy to loading and unloading, can reuse; The utlity model has simple in structure, easy to install, do not damage equipment, safe and reliable characteristics, remedied the deficiency that existing ladder upper end swings back and forth, do not influence the normal carrying of ladder and attractive in appearance simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of fastening devices among Fig. 1.
The specific embodiment
By Fig. 1 and Fig. 2 as can be seen, this electric power overhaul ladder comprises ladder 11, wherein, ladder 11 upper ends are provided with fastening devices, and fastening devices is mainly by fixing card 1, rotating shaft 2, be arranged on the spring 3 in the rotating shaft 2, connecting rod 9 constitutes, and fixing card 1 and connecting rod 9 are hinged by rotating shaft 2.Connecting rod 9 is provided with screw hole 10, and connecting rod 9 is connected with ladder 11 by screw, also is provided with shop bolt 5 on the connecting rod 9, and shop bolt 5 is hinged by pin rotating shaft 4 and connecting rod 9, also is provided with rotating shaft spring 7 in the pin rotating shaft 4.
Be it can also be seen that by Fig. 2 fixed card 1 inboard is semi-circular and the square integrated structure, semi-circular structure is adopted in connecting rod 9 inboards, and installs slipmat additional in fixed card 1 and connecting rod 9 inboards.
Be it can also be seen that by Fig. 1 and Fig. 2, be equipped with retainer plate 6 on fixed card 1 and the connecting rod 9, also being provided with flexible rope 8 on the fixture, flexible rope 8 one ends are connected with retainer plate on the fixed card.
Fixed card 1 is the die cast metal moulding with connecting rod 9, to strengthen its intensity; Its shape of cross section can be decided according to ladder 11 upper end shapes.
Using method of the present utility model is:
At first this device connecting rod 9 is connected and can start working with ladder 11 usefulness rivets or with screw before the work.The flexible rope 8 of pulling when work, shop bolt 5 and fixed card 1 rotate counterclockwise centered by rotating shaft 2 and pin rotating shaft 4, this moment, round steel or channel-section steel can snap in the fixture, unclamp flexible rope 8, shop bolt 5 and fixed card 1 clockwise rotate reinstatement under the active force of spring 3 and rotating shaft spring 7, this moment, round steel or channel-section steel fixedly secured in fixture.
