The fixed hoop and the sliding hoop are symmetrical clips which surround a pole; one end of the fixed hoop is fixedly connected with the right part of the guide rail through a piece of connection steel channel; and the slide block of the sliding hoop is a slide sleeve. The ladder with the sliding hoop, disclosed by the invention, is simple in structure and practical; the sliding hoop moves towards the pole to be matched with the fixed hoop; and the ladder and the pole are firmly fixed so that an operator can smoothly climb the pole for work, the number of constructors can be reduced, and human injuries are avoided.
Description
Technical field
The present invention relates to a kind of ladder, in particular for the ladder of electric pole maintenance.
Background technology
In electric power overhaul operation, operator is often needed to climb the electric pole of more than 18 meters, because bar base portion position diameter is large, climbers gripping arm adjustable amplitude is little, operating personnel cannot directly climb at bar base portion, needs to climb electric pole 3 meters of At The Heights with ladder, climbers could be used upwards to climb.And common ladder needs to lean against on electric pole, contact site can not form stable contact surface, in addition Overhaul site ground condition is complicated, in the wild during ground construction, often there is rough landform at electric pole foundation place, although have special messenger to hold up to keep and ladder also very easily occurs to tumble phenomenon, there is the accident of stepping on the tumble injury of bar personnel high falling; On bar, operating personnel is careless slightly, is come off by instrument, can injure staircase personnel under bar.In order to avoid accident, some ladder tops have been installed fixing anchor ear and have been surrounded by electric pole and hold tightly.But because electric pole model different-diameter is different, the electric pole of different-diameter can not be surrounded at ladder top installation fixing anchor ear and hold tightly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ladder with sliding anchor ear, have easy and simple to handle fast, guarantee safety, the electric pole of different-diameter can be surrounded the feature of holding tightly.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of ladder with sliding anchor ear, comprises ladder, it is characterized in that: described ladder upper end is provided with guide rail, fixing anchor ear and sliding anchor ear; Described fixing anchor ear is fixedly connected with guide rail right part, and slide block and the guide rail left part of described sliding anchor ear are slidably matched, and the side of described ladder is provided with the slide-and-lock device be connected with sliding anchor ear.
: described fixing anchor ear and sliding anchor ear are the symmetrical clamp surrounding electric pole that one end of described fixing anchor ear is fixedly connected with guide rail right part by connecting channel-section steel, and the slide block of described sliding anchor ear is sliding sleeve to the further improvement that the present invention does.Described slide-and-lock device comprises control spanner, fixed pulley, sleeve pipe and pull rope; Described control spanner is rectangular flat plate, and the right side controlling upper end and the ladder of spanner is hinged, and the middle part of control spanner is provided with cross bar, and described fixed pulley is positioned at the right-hand member on ladder top, and described sleeve pipe is connected with on the right side of ladder by junction plate; One end of described pull rope is connected with the slide block of sliding anchor ear, and the other end, through the inner chamber of the connection channel-section steel of fixing anchor ear, is connected with described cross bar through sleeve pipe through fixed pulley.
Adopt the beneficial effect that produces of technique scheme to be: simple and practical, have easy and simple to handle fast, guarantee safety, the electric pole of different-diameter can be surrounded the feature of holding tightly.Moved to electric pole by sliding anchor ear, coordinate with fixing anchor ear, ladder and electric pole are fixedly secured, operating personnel can climb bar operation smoothly, reduce constructor, avoid personal injury.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
As shown in the figure: 1 ladder, 2 guide rails, 3 slide blocks, 4 fixing anchor ears, 5 fixed pulleys, 6 pull ropes, 7 sleeve pipes, 8 cross bars, 9 control spanner, 10 sliding anchor ear, 11 electric poles.
Detailed description of the invention
Contrast Fig. 1-2 uses step to be described further to operation of the present invention:
With a ladder for sliding anchor ear, comprise ladder 1, it is characterized in that: described ladder 1 upper end is provided with guide rail 2, fixing anchor ear 4 and sliding anchor ear 10; Described fixing anchor ear 4 is fixedly connected with guide rail 2 right part, and slide block 3 and guide rail 2 left part of described sliding anchor ear 10 are slidably matched, and the side of described ladder 1 is provided with the slide-and-lock device be connected with sliding anchor ear 10.Described fixing anchor ear 4 and sliding anchor ear 10 are the symmetrical clamp surrounding electric pole 11, and one end of described fixing anchor ear 4 is fixedly connected with guide rail 2 right part by connecting channel-section steel, and the slide block 3 of described sliding anchor ear 10 is sliding sleeve.Described slide-and-lock device comprises control spanner 9, fixed pulley 5, sleeve pipe 7 and pull rope 6; Described control spanner 9 is rectangular flat plate, and the right side controlling upper end and the ladder 1 of spanner 9 is hinged, and the middle part of control spanner 9 is provided with cross bar 8, and described fixed pulley 5 is positioned at the right-hand member on ladder 1 top, and described sleeve pipe 7 is connected with on the right side of ladder 1 by junction plate; One end of described pull rope 6 is connected with the slide block 3 of sliding anchor ear 10, and the other end, through the inner chamber of the connection channel-section steel of fixing anchor ear 4, is connected with described cross bar 8 through sleeve pipe 7 through fixed pulley 5.
Upkeep operation starts, and first ladder 1 is leaned against on electric pole 11, and fixing anchor ear 4 is positioned at the right side of electric pole 11, and sliding anchor ear 10 is positioned at the left side of electric pole 11, and the pull rope 6 controlled on spanner 9 uses wire rope, and wire rope is connected with the slide block 3 in sliding anchor ear 10.Then descend pressure-controlled spanner 9, wire rope makes sliding anchor ear 10 slide to electric pole 11 along guide rail 2 to be close to, and two anchor ears hold electric pole 11 tightly, and ladder 1 firmly leans against on electric pole 11, and operator can start to climb bar operation.Inspection operation terminates, and constructor gets off from electric pole 11, by lift control spanner 9, unclamp wire rope, sliding anchor ear 10 is unclamped thereupon, and ladder 1 can be put into ground easily.
