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

A kind of ladder that has sliding anchor ear
Technical field
The present invention relates to a kind of ladder, in particular for the ladder of electric pole maintenance.
Background technology
In the electric power overhaul operation, often need the operator to climb electric pole more than 18 meters, because bar base portion position diameter is big, but climbers gripping arm adjusting range is little, the operating personnel can't directly climb at the bar base portion, need climb electric pole with ladder and highly locate for 3 meters, could use climbers upwards to climb.And common ladder need lean on electric pole, the contact site can not form stable contact surface, overhaul on-the-spot ground condition complexity in addition, in the open air during ground construction, often there is rough landform at electric pole foundation place, though have the special messenger to hold up to keep the ladder phenomenon of tumbling taking place very easily also, the accident of bar personnel high falling tumble injury occurs stepping on; The operating personnel is careless slightly on bar, and instrument is come off, and can injure staircase personnel under the bar.For fear of accident, the ladder top that has has been installed fixedly anchor ear and electric pole is surrounded has been held tightly.But because electric pole model different-diameter difference, install and fix anchor ear on the ladder top and the electric pole of different-diameter can not be surrounded and hold tightly.
Summary of the invention
Technical problem to be solved by this invention provides a kind of ladder that has sliding anchor ear, have easy and simple to handle fast, guarantee safety, the electric pole of different-diameter can be surrounded the characteristics 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 that has sliding anchor ear, comprise ladder, and it is characterized in that: described ladder upper end is provided with guide rail, fixedly anchor ear and sliding anchor ear; Described fixedly anchor ear is fixedlyed connected with the guide rail right part, and the slide block of described sliding anchor ear and guide rail left part are slidingly matched, and a side of described ladder is provided with the slide-and-lock device that is connected with sliding anchor ear.
The further improvement that the present invention is done is: described fixedly anchor ear and sliding anchor ear are the symmetrical clamp that surrounds electric pole, and an end of described fixedly anchor ear is fixedlyed connected with the guide rail right part by connecting channel-section steel, and the slide block of described sliding anchor ear is sliding sleeve.Described slide-and-lock device comprises control spanner, fixed pulley, sleeve pipe and pull rope; Described control spanner is rectangular flat plate, and the upper end of control spanner and the right side of ladder are 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 the ladder right side by junction plate; One end of described pull rope is connected with the slide block of sliding anchor ear, and the other end passes the fixedly inner chamber of the connection channel-section steel of anchor ear, passes sleeve pipe through fixed pulley and is connected with described cross bar.
The beneficial effect that adopts technique scheme to produce is: simple and practical, have easy and simple to handle fast, guarantee safety, the electric pole of different-diameter can be surrounded the characteristics of holding tightly.Move to electric pole by sliding anchor ear, cooperate with fixing anchor ear, ladder and electric pole are fixedly secured, operating personnel can climb the bar operation smoothly, reduce the constructor, avoid personal injury.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
As shown in the figure: 1 ladder, 2 guide rails, 3 slide blocks, 4 are anchor ear, 5 fixed pulleys, 6 pull ropes, 7 sleeve pipes, 8 cross bars, 9 control spanners, 10 sliding anchor ear, 11 electric poles fixedly.
The specific embodiment
Contrast Fig. 1-2 uses step to be described further to operation of the present invention:
A kind of ladder that has sliding anchor ear comprises ladder 1, it is characterized in that: described ladder 1 upper end is provided with guide rail 2, fixedly anchor ear 4 and sliding anchor ear 10; Described fixedly anchor ear 4 is fixedlyed connected with guide rail 2 right parts, and slide block 3 and guide rail 2 left parts of described sliding anchor ear 10 are slidingly matched, and a side of described ladder 1 is provided with the slide-and-lock device that is connected with sliding anchor ear 10.Described fixedly anchor ear 4 and sliding anchor ear 10 are the symmetrical clamp that surrounds electric pole 11, and an end of described fixedly anchor ear 4 is fixedlyed connected with guide rail 2 right parts 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 upper end of control spanner 9 and the right side of ladder 1 are 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 ladder 1 right side 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 passes the fixedly inner chamber of the connection channel-section steel of anchor ear 4, passes sleeve pipe 7 through fixed pulley 5 and is connected with described cross bar 8.
Upkeep operation begins, and at first ladder 1 is leaned against on the electric pole 11, and fixedly 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 of control on the spanner 9 uses wire rope, and wire rope is connected with slide block 3 on the sliding anchor ear 10.Descend pressure-controlled spanner 9 then, wire rope makes sliding anchor ear 10 slide along guide rail 2 and is close to electric pole 11, and two anchor ears are held electric pole 11 tightly, ladder 1 firm leaning against on the electric pole 11, and the operator can begin to climb the bar operation.Inspection operation finishes, and the constructor gets off from electric pole 11, by on lift control spanner 9, unclamp wire rope, sliding anchor ear 10 is unclamped thereupon, ladder 1 can be put into ground easily.
