Due to the above-mentioned technical scheme, the utility model has the following advantages:

The beam at the top of the ladder frame is designed as an arc-shaped top beam, which is stuck on the utility pole to prevent the ladder frame from shaking left and right. The hoop and ladder buckle set on the beam lock the ladder frame on the utility pole. Sliding down, the surface of the ladder buckle is designed with thin corrugated strips to further improve the safety of the construction ladder. Safety devices are fixed on the lower ladder frame at both ends of the beam to provide an extra layer of safety for construction workers. The ladder buckle adopts a telescopic structure , can adapt to different diameters of poles, and has a wide range of applications.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

Please refer to Figures 1 to 3. In the embodiment of the utility model, a construction ladder that can be fixed on a utility pole for electric power construction includes a ladder frame 1, a beam 2, an arc-shaped top beam 3, a ladder buckle, a hoop and a safety device A number of crossbeams 2 are set between the ladder frames 1 for construction workers to climb up through the crossbeams. The crossbeams at the top of the ladder frame 1 are curved top beams 3. Elastic rope 15, fixed safety belt 16 in the middle of elastic rope 15; The hoop is installed in the middle of arc top beam 3, hoop comprises, hoop crossarm 12, upper hoop 13 and lower hoop 14, last hoop 13 and The lower hoop 14 relatively forms a quasi-circular cavity, which is wrapped on the arc-shaped top beam 3 through the cooperation of bolts and nuts. Threaded holes are provided at both ends of the hoop cross arm 12, and through the cooperation of bolts and nuts, the ladder buckle cross arm 11 Fixed together, the ladder buckle includes ladder buckle cross arm 11, connecting rod 10, moon plate 9, rubber 8, fixed ring arm 7, thin corrugated strip 6, telescopic ring arm 5 and sleeve 4, ladder buckle cross arm 11 is fixedly connected to the bottom of the moon-shaped plate 9 through the connecting rod 10 (the moon-shaped plate 9 is a sheet material with a certain radian), and the bottom of the moon-shaped plate 9 is also provided with a fixed ring arm 7, and one end of the fixed ring arm 7 is fixed on the moon-shaped plate 9, the other end of the fixed ring arm 7 is equipped with a sleeve 4, the sleeve 4 is set on the telescopic ring arm 5 to slide freely, and is fixed and locked with the sleeve 4 under the action of the fastening bolt, and the telescopic ring arm 5 is removed from the The upper sliding part of the sleeve 4, the inner side of the ring arm and the upper surface of the moon-shaped plate 9 are all equipped with a rubber 8, and the rubber 8 is fixed by countersunk screws. flute.

The working principle of the utility model is:

When using the utility model, it is necessary to adjust the distance between the telescopic ring arm and the fixed ring arm by fastening bolts according to the diameter of the utility pole, and then the arc-shaped top beam 3 at the top of the ladder frame 1 is stuck on the utility pole to prevent The ladder frame 1 shakes from side to side. In addition, the utility pole needs to be clamped between the telescopic ring arm and the fixed ring arm of the ladder buckle, and the ladder frame 1 is moved backward so that the ladder buckle 1 is locked on the utility pole. The construction workers pass through the beam 2, Hold the ladder frame 1 to climb up, after touching the safety device, the safety belt 16 is tied on the waist of oneself, because the connecting rope at the two ends of the safety belt is an elastic rope 15, even if the worker accidentally falls, the elastic rope can also rise up. It has a good cushioning effect and avoids physical discomfort to the workers under the action of inertia; on the other hand, as the device’s service time increases, the rubber 8 will gradually wear out, exposing the head of the countersunk screw, reducing the The contact area between the rubber 8 and the utility pole affects the anti-skid effect of the ladder buckle, so thin corrugated strips 6 are arranged at the corresponding places of the ladder buckle and the rubber 8, which not only plays the role of auxiliary anti-skid, but also ensures the safety and security of the device. durability.
