Abstract
An automatic extension ladder device of a working platform belongs to the technical field of petroleum drilling and workover devices. The automatic extension ladder device consists of a guide rail ladder (4), a slide (1), a detachable handrail a (2) and a detachable handrail b (3). A hook at the upper end of the guide rail ladder (4) is hung on the light working platform, the upper plane of the guide rail ladder is adjusted to be flush with the light working platform, the slide (1) freely slides in a slide way to the ground by means of self gravity, then the detachable handrail a (2) and the detachable handrail b (3) are inserted in an inserting pipe of the slide (1), and all of pedal plates of the slide (1) are novel anti-skidding saw-toothed pedal plates so that the self safety is increased. The automatic extension ladder device of the working platform is convenient to install, detach and adjust, and the safety of workers climbing up and down the ladder is increased.
Description
One, technical field:
The automatic extension ladder device of a kind of workbench belongs to oil drilling and repairing well equipment technical field.
Two, background technology:
When vehicle-mounted drilling well of oil or workover treatment; Need the light-duty working platform that to regulate height; Platform and ground are connected with the passage of a ladder as last lower platform; Platform can be regulated height, but common ladder but can not, walking in the above with common ladder has increased the danger of stumbling greatly.Original ladder can not satisfy the demand that can regulate highly light-duty working platform.
Three, summary of the invention:
The utility model is to a plurality of height adjustment of supporting light-duty workbench on oil vehicle-mounted drilling and workover machines Y type frame and the derrick, a kind of automatic extension ladder device of designing and developing.This automatic extension ladder device is applicable to all the oil car that light-duty workbench is installed dress drilling and workover machines.The technical scheme that the utility model is taked is: the automatic extension ladder device of a kind of workbench; Form by guide rail ladder (4), slide (1), dismantled and assembled railing a (2), dismantled and assembled railing b (3); It is characterized in that dismantled and assembled railing a (2) is inserted on the slide (1), dismantled and assembled railing a (2) can slide with slide (1).
All foot rests of this slide all adopt new-type antiskid zigzag pedal to increase the safety of himself.The utlity model has installation, dismounting, easy to adjust, increased workman's safety of cat ladder up and down.
Four, description of drawings:
Accompanying drawing is this apparatus structure sketch map
Among the figure: 1. slide; 2. dismantled and assembled railing a; 3. dismantled and assembled railing b; 4. guide rail is terraced.
Five, the specific embodiment:
Instance 1, the automatic extension ladder device of a kind of workbench; Form by guide rail ladder (4), slide (1), dismantled and assembled railing a (2), dismantled and assembled railing b (3); It is characterized in that dismantled and assembled railing a (2) is inserted on the slide (1), dismantled and assembled railing a (2) can slide with slide (1).
Claims (1)
1. the automatic extension ladder device of workbench is made up of guide rail ladder (4), slide (1), dismantled and assembled railing a (2), dismantled and assembled railing b (3), it is characterized in that dismantled and assembled railing a (2) is inserted on the slide (1), and dismantled and assembled railing a (2) can slide with slide (1).
