Abstract
The utility model relates to a ladder, and in particular relates to the ladder specialized for maintaining overhead transmission lines. The ladder comprises a frame and stepping ladders; the special-purpose ladder also comprises a U-shaped clamping groove opened downwards; one sidewall of the U-shaped clamping groove is connected with the upper end of the frame; and a plane of the U-shaped clamping groove is vertical to that of the frame. The special-purpose ladder has the characteristics that the special-purpose ladder can be more stably fixed on steel angles by using the U-shaped clamping groove and a clamping hook, so that the security factor of operators is increased; and besides, the special-purpose ladder is made of glass resin, so that the hardness of the special-purpose ladder is higher, the weight is lighter, the shake of the operators overhead is reduced, the working difficulty of the operators is reduced and the working efficiency is increased.
Description
Technical field
The utility model relates to a kind of ladder, more specifically a kind of steel tower ladder special for transmission line inspection.
Background technology
Needs along with the management of the rigidity of present power failure, often task is many, the time short for interruption maintenance, carrying out some conventional overhauling projects, as change the straight line synthetic insulator, drive folder and check, change stockbridge damper etc., steel tower cross-arm outboard angle is " L " type, and existing mode is rope ladder to be fixed on " L " angle steel, this mode mainly has the following disadvantages: for security needs, carefully the colligation rope ladder head is guaranteed personal safety, loses time very much; Rope ladder rocks severity in the high-altitude, and wire influence is very large up and down to the operating personnel, has increased up and down difficulty, greatly reduces operating safety factor; Rope ladder length is fixed, and the 110kV circuit is installed inconvenience, has greatly increased the activity duration.
Summary of the invention
For above deficiency, the utility model provides a kind of safe, few ladder special for transmission line inspection of losing time.
The utility model is achieved through the following technical solutions:
A kind of steel tower ladder special for transmission line inspection comprises the ladder with framework and pedal, and special-purpose ladder also comprises the U-shaped draw-in groove that Open Side Down, and U-shaped draw-in groove one sidewall is connected with the framework upper end, and plane, U-shaped draw-in groove place is vertical with plane, framework place.
The sidewall thickness of above-mentioned U-shaped draw-in groove is identical with the thickness of framework.
There is the buckle that is connected by screw with U-shaped draw-in groove above-mentioned U-shaped draw-in groove upper end, a progressive stability of guaranteeing to overhaul special-purpose ladder.
The material of above-mentioned ladder special for transmission line inspection is glass resin, and this material makes maintenance special-purpose ladder hardness high, and quality is light.
The beneficial effects of the utility model are: can make more stable being fixed on the angle steel of maintenance special-purpose ladder by U-shaped draw-in groove and snap fit, improve staff's coefficient of safety; Using simultaneously glass resin to be material, is that special-purpose ladder hardness is high, and quality is light, has reduced that the staff is skyborne to be rocked, and has alleviated staff's work difficulty, increases work efficiency.
Description of drawings:
Fig. 1 is front view of the present utility model;
Fig. 2 is the left view of the utility model when not working;
Left view when Fig. 3 is the utility model work;
Among the figure: 1-ladder, 2-framework, 3-pedal, 4-U type draw-in groove, 5-buckle, 6-screw, 7-" L " type angle steel.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further, so that those skilled in the art can better understand the utility model, but does not therefore limit the utility model.
A kind of steel tower ladder special for transmission line inspection, comprise the ladder 1 with framework 2 and pedal 3, special-purpose ladder also comprises the U-shaped draw-in groove 4 that Open Side Down, U-shaped draw-in groove 4 one sidewalls are connected with framework 2 upper ends, plane, U-shaped draw-in groove 4 place is vertical with plane, framework 2 place, the sidewall thickness of U-shaped draw-in groove 4 is identical with the thickness of framework, there is the buckle 5 that is connected by screw 6 with U-shaped draw-in groove 4 U-shaped draw-in groove 4 upper ends, a stability of guaranteeing to overhaul special-purpose ladder can improve, the material of ladder special for transmission line inspection is glass resin, this material makes maintenance special-purpose ladder hardness high, and quality is light.During use, U-shaped draw-in groove 4 is snapped in the part that " L " type angle steel 7 projects upwards, then buckle 5 is fastened the bottom of " L " type angle steel, screwing screw 6, fixedly ladder special for transmission line inspection.
