Detailed description of the invention
As shown in Fig. 1 to Fig. 5, the maintenance ladder of a kind of band telescopic leg, mainly it is made up of base 1, newel 2 that multi-segment structure is identical, footstock 3, the connecting shaft 4 that footstock is fixed on upper level newel.
Described newel is cylindricality, the sidewall of newel is provided with outwardly mark time 21.During use, maintainer is stepped on to mark time and is climbed up and down on maintenance ladder.
Newel is many side columns or cylinder, preferably cylinder.The downward projection of maximum gauge polygon locating dowel 22 less than newel diameter it is provided with bottom every section of newel 2, accordingly, Mei Duan center capital also is provided with the locating dowel with upper level and forms the hole, polygon location of friction tight concave downward, newel is sequentially connected in series together, the polygon locating dowel 22 of newel above inserts the hole, polygon location that the center of next stage is pushed up surely from top to bottom, both form tight fit, lateral strength is imposed at newel outer wall, newel will not rotate due to the positioning action of polygon locating dowel, newel rotates generation danger to make maintainer not worry when climbing down on maintenance ladder swashes.
Base top is provided with fixing post 11 upwardly, the polygon locating dowel with newel being provided with concave downward on fixing capital forms friction tight fixing hole, and the fixing hole on the polygon locating dowel of next stage newel inserted base 1 from top to bottom top is fixed.
Described connecting shaft 4 bottom be with on the capital of center polygon position hole be the friction tight post that is connected, the top of connecting shaft is cylinder, is provided with the cylindrical hole of concave downward on the roof of the cylindrical portion of connecting shaft；It is provided with at the bottom of described footstock to be formed with the cylindrical hole on connecting shaft top and friction tight is connected seat；The post that connects of connecting shaft is inserted the location, hole, polygon location of the central shaft being positioned at the top from top to bottom, again the seat that connects at the bottom of footstock is inserted the connection seat on connecting shaft top from top to bottom, making footstock be placed on connecting shaft top, under the effect of external force, footstock can rotate on connecting shaft top.Sometimes for easy to operate, when maintainer needs repairing the equipment being positioned at its health side, by twisting health to side, it becomes possible to make footstock generation lateral rotation, make maintainer transfer in the face of the original equipment in its side, keep in repair to facilitate.
Polygon locating dowel lower central at newel arranges the diameter downward projection of cylinder 24 less than polygon locating dowel minimum diameter, accordingly, the cylindrical hole of concave downward it is provided with on the diapire in the hole, polygon location on the capital of center, when the polygon locating dowel of upper level newel inserts the hole, polygon location on the capital of next stage center, the cylinder of upper level newel inserts the cylindrical hole on the capital of next stage center.When the hole, polygon location that the polygon locating dowel of upper level newel is downwardly on next stage newel, cylinder plays the effect of guiding, owing to its diameter is less, it is easily inserted in hole, polygon location, making polygon locating dowel enter hole, polygon location by rotation the most again, cylinder will be easily downwardly in cylindrical hole.
The fixing hole of the fixing post of the polygon locating dowel inserted base of next stage newel, the cylinder of next stage newel is downwardly into stop bit post 15 through fixing post.
Base disposes on the ground, it is inserted on base top after newel concatenation, finally footstock is fixed on by connecting shaft and most goes up above a pole newel, after maintainer is climbed in maintenance ladder top, sit on and on footstock, carry out maintenance work, step on again to mark time after having keeped in repair and return to ground.
Footstock is provided with handrail upwardly, and handrail is provided with hook.In maintenance process, generally to use some maintenance tools and auxiliary appliance, the most also can pull down some problematic parts from maintenance product, therefore, maintainer is generally required for carrying the satchel that can place maintenance tool and auxiliary appliance, after climbing on footstock, satchel always hang over people the most tired, therefore, footstock arranges hook, satchel is hung on hook by maintainer, in maintenance process, can hold handrail at any time to keep the balance of health to prevent danger.
Described mark time be shaped as sector or square.Marking time, end face upward is provided with lug, nib or groove, to increase the frictional force that maintainer sole is trampled on marking time, prevents from skidding.
Described base 1 mainly includes fixing 11, three or four discoid suckers 12 of post, support shaft 13, eccentric spanner 14；Being wrapped in one piece below described sucker diapire and have resilient rubber, the surrounding of rubber upwards wraps the bottom of sucker；With the lug axle on fixing post 11 outer wall even, the other end is with the lug axle on sucker roof even in described support shaft 13 one end；Described eccentric spanner is placed on sucker, eccentric spanner includes spanner, guide pile and location dish, described guide pile passes sucker from top to bottom along the central shaft of sucker, location dish is located on guide pile end down, location dish is positioned at below rubber, the top of guide pile is positioned at above sucker roof, the top of guide pile connects with the terminal shaft of spanner, the lower section of spanner and guide pile axle one end even is provided with stop block, on stop block between spanner and the guide pile axle position central shaft at stop block and the edge of the stop block away from support shaft even, guide pile is positioned at the height more than stop block of the height above sucker.
When spanner is removed downwards make stop block be pushed against on sucker top time, the front end of stop block is pushed against support shaft and sucker axle end even, makes support shaft can not rotate under the effect of external force, and at this moment, sucker is pressed on ground by location dish and rubber.
When spanner is upwards removed make the front end of stop block be against on sucker top to make spanner the most upwards to remove time, location dish moves up the middle part upwards jack-up of rubber wall down, location dish is made to leave ground, sucker can be mentioned from ground, stop block leaves support shaft, and support shaft can rotate under the effect of external force.
Below fixing post 11, it is provided with the cylinder 24 below the cylindrical stop bit post 15 of upper and lower opening, the endoporus of stop bit post 15 and newel forms tight fit, enable the cylinder of the newel of next stage to move up and down in stop bit post endoporus；Stop bit post 15 is connected with support shaft 13 by position-arresting axis 16, and even, the other end of position-arresting axis is with the lug axle on stop bit column outer wall even for the lug axle in the middle part of one end of position-arresting axis and support shaft；The quantity of position-arresting axis is identical with the quantity of support shaft；After spanner above a sucker is upwards removed, this sucker can leave ground under the effect of external force, move position-arresting axis, the angle of position-arresting axis and support shaft can be changed, so that this sucker is closer or far from stop bit post, again sucker being pressed onto ground, then spanner is moved to downwards after stop block pushes against sucker top, stop block pushes against support shaft.
Therefore, by upwards spanner, then the angle of position-arresting axis and support shaft is changed, it becomes possible to change the height of base, by pressure spanner, it becomes possible to the height of firm banking.The extreme lower position that base can regulate is to be positioned at the cylinder 24 of the newel of next stage to enter fixing post 11 and polygon locating dowel wall down is against on fixing capital.
Above-described embodiment is intended merely to interpretation purposes of the present utility model; and be not to restriction of the present utility model, those skilled in the art, in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
