Abstract

The invention provides a lifting working ladder, a set of movable steps are added between fixed steps and a lifting platform, step supports of the movable steps are in linkage with the lifting platform in a fixed mode, movable footsteps of the movable steps are connected with sliding rails on the two sides in a sliding mode so that the working ladder is lifted to any height within the travel distance, and all the moveable steps can provide continuous stepping so that a constructor can conveniently step on and step down the working platform.

Description

A kind of elevating ladder

Technical field

The present invention relates to a kind of universal grounding equipment, specifically a kind of elevating ladder.

Background technology

Working stand is widely used in various work-sites, and its purpose is for the workmen provides the operation height, the workmen to be constructed to standing in the untouchable driving surface in ground.Common working stand is divided into standing height working stand and elevating ladder.The erect-position plane of elevating ladder can lifting, and commonality is good, can be suitable for the driving surface to differing heights to construct.At present the using method of common elevating ladder mostly is: when the flat surface of elevating ladder is down to lowest order, the workmen climbs up flat surface by fixing step, and then jacking system is increased to operating altitude with flat surface and workmen.Complete or need to be down to ground the time when workmen's operation, must reduce podium level by jacking system, the workmen could descend ground.If long or workmen needs repeatedly go up lower platform at the production time of same operating altitude, just need the repeatedly lifting of service platform face, extended the engineering time, reduced work efficiency.

Summary of the invention

Purpose of the present invention: in order to solve elevating ladder at various height, workmen's upper lower platform problem, the application provides a kind of elevating ladder, by fixedly increasing the movable step of a cover between step and lifting table, make working stand be elevated to arbitrary height in stroke, movable step can provide continuously marks time, and the gradient of marking time continuously is between 20 ° to 80 °, and the convenient construction personnel are workplatform up and down.

A kind of elevating ladder, formed with the stepladders that is communicated with lifting table by the lifting table that is fixed on movable framework, it is characterized in that described stepladders contains fixedly step and movable step, the traveling table component level is in fixedly between step and lifting table, described movable step is comprised of Active foot plate and the step support that is positioned at Active foot plate below, the fixing interlock of this step support and described lifting table, the two ends of described Active foot plate are slidably connected on the trapped orbit of both sides.

Beneficial effect of the present invention is, Active foot plate with lifting table interlock, so need not operation bidirectional during lifting table under the effect of step support, just can make the upper lower channel of the servo-actuated one-tenth lifting table of movable step, fixedly step is communicated with lifting table, facilitates the staff up and down.Both sides due to Active foot plate are embedded on trapped orbit again, make the reliability of movable step high, use, and maintenance cost is cheap, commonality good, is easy to apply, and is conducive to improve workmen's work efficiency, has practical value very much.

Below in conjunction with the embodiment accompanying drawing, this application is described in further detail:

The specific embodiment

The present invention is described in further detail below by specific embodiment:

Referring to accompanying drawing, the elevating ladder that the present embodiment provides is the ground frock for the Aircraft Production trim designs.In order to facilitate working stand at the integrated moving of work-yard, lifting table 1 and the working stand that leads to lifting table are fixed on movable framework 8 simultaneously, the power that provides of the rise of lifting table 1 or landing is provided jacking equipment 7, fixedly step has three rank, formed by the pedal that is fixed on movable frame, be fixedly the movable steps 3 in three rank between step 2 and lifting table 1, movable step 3 is comprised of Active foot plate 4 and step support 5.The step support 5 of this activity step and lifting table Coupled motion, in enforcement, the step support can with the integrally welded structure of lifting table, also can fix by other connection modes.The Active foot plate of movable step is embedded on the trapped orbit 6 of guardrails of both sides plate successively.Form a platform in order to accept Active foot plate at lowest part, there are the support shelves of equal height the trapped orbit lower end of Active foot plate both sides, when lifting table 1 drops to nadir.Active foot plate 4 drops to trapped orbit 6 lowest parts in the effect of deadweight, and this moment, Active foot plate 4 track 6 end stoppers that are fixed held up, and held up height with fixedly step 2 is concordant with lifting table 1, and the three forms the plane.When lifting table 1 rises to certain altitude, step support 5 holds up Active foot plates 4, forms and marks time continuously.When lifting table 1 is raised to the extreme higher position, step support 5 holds up all Active foot plates 4 fully.Optional position in stroke, movable step 3 can form the upper lower channel that is connected and fixed step 2 and lifting table 1.

Claims

1. elevating ladder, formed with the stepladders that is communicated with lifting table by the lifting table that is fixed on movable framework, it is characterized in that described stepladders contains fixedly step and movable step, the traveling table component level is in fixedly between step and lifting table, described movable step is comprised of Active foot plate and the step support that is positioned at Active foot plate below, the fixing interlock of this step support and described lifting table, the two ends of described Active foot plate are slidably connected on the trapped orbit of both sides.

2. elevating ladder as claimed in claim 1, there are the support shelves of equal height the trapped orbit lower end that it is characterized in that described Active foot plate both sides.
