Abstract
The utility model relates to an oil-field special vehicle rear ladder which is used to be trampled by the operations when getting on or getting off the vehicles. The utility model consists of a sliding track (2), a slide (3) and a rotating ladder (4). The slide (3) is arranged in the sliding track (2) and can slide along the track. The rotating ladder (4) is in quadrangle and is connected with the slide (3) by two groups of pin. The rear ladder of the utility model is of reasonable design. The cantilever is of parallelogram grounding structure. The utility model is of handsome sculpting, and can be used for vehicles of a variety of types. The utility model is of good adaptability, and can be widely promoted.
Description
Technical field
The utility model relates to a kind of oil field special machine, particularly the back ladder of trampling during car body up and down for operating personnel on the special-purpose vehicle of oil field.
Background technology
Back ladder is widely used in various oil field special-purpose vehicle supply equipment operating personnel and tramples during car body up and down.From present domestic situation at the oil field of usefulness special engineering vehicle, there is following some weak point in existing back ladder:
1), span is too big, do not meet the human engineering design principle.Because all types of oil fields special-purpose vehicle car body height off the ground is higher relatively, and common back ladder mostly is the single stage type structure owing to be subjected to the space of car body and the restriction of self structure, and the height upper span is bigger, is not suitable for the equipment operator and tramples up and down the time.
2), rigidity is relatively poor.Conventional back ladder mostly is cantilever construction, partly is fulcrum with the car body bumper, and engineering truck with vehicle owing to often have about the equipment operator bears a heavy burden, therefore common back ladder is usually owing to can't bear heavy burden and produces and be out of shape even cause the drawing crack of junction.
3), skid resistance is poor.Common back terraced pedal adopts checkered steel plate or aluminium sheet more, and antiskid function is relatively poor relatively.Especially at pedal oil stain, water stain or in cold season in winter is arranged, exist very big potential safety hazard.
Summary of the invention
The present utility model purpose is at the common above shortcoming of ladder behind the special engineering vehicle of oil field, adopts new structure, technology and material, and the back common many shortcomings of ladder are overcome one by one.Specifically, design scheme is:, ladder behind the special-purpose vehicle of a kind of oil field, by slide rail (2), slide (3), change ladder (4) and constitute, slide (3) is positioned at slide rail (2) and can slides thereon, changes ladder (4) and is quadrilateral structure and link together by two groups of bearing pins and slide (3).
At the terminal fixing bumper block of making by elastomeric material (1) of slide rail (2), when being used to reduce gliding mass and packing up to the impact of slide rail.
Connect two groups of bearing pins that change ladder (4) and slide (3), one group of bearing pin rotates, and another group bearing pin slides in slide bearing pin chute.This connected mode is convenient to closing up of parallelogram commentaries on classics ladder or is opened.
Slide (3) and the pedal that changes on the ladder (4) are that the flute profile anti-skid structure is to strengthen the antiskid function of pedal, the minimizing potential safety hazard.
The utility model operating principle is briefly described as follows:
1), take off alignment pin 1, back ladder job order when transferring:; 2), pulling changes ladder backward, transfer when putting in place.
1), pull-up changes ladder and push away forward 2, back ladder job order when packing up:; When 2), putting in place alignment pin is plugged back ladder pinning.
Ladder is reasonable in design behind the utility model, changes cantilever construction and is parallelogram and land structure, and is handsome in appearance, is applicable to multi-form vehicle, and applicability is good, is beneficial to large-scale popularization.

The specific embodiment
Ladder behind the special-purpose vehicle of a kind of oil field, by slide rail 2, slide 3, change ladder 4 and constitute, slide 3 is positioned at slide rail 2 and can slides thereon, slide rail 2 is fixed on the automobile pair crossbeam, when back ladder was transferred, the slide rail front end was the strong point, when packing up after terraced integral body be hidden within the chute.Slide 3 slides in slide rail by pulley, on the one-level pedal is arranged, pedal is the profile of tooth anti-skid structure.Change ladder 4 and link together by two groups of bearing pins and slide, one group of bearing pin rotates, and another is organized bearing pin and slides in slide bearing pin chute.Bumper block 1 is fixed on the slide rail, when being used to reduce slide and packing up to the impact of slide rail.Ladder is fixing after when alignment pin is used to drive a vehicle, and joins to be welded in the hull back bumper.
Claims (4)
1, ladder behind the special-purpose vehicle of a kind of oil field is characterized in that by slide rail (2), slide (3), changes ladder (4) and constitute, and slide (3) is positioned at slide rail (2) and can slides thereon, changes ladder (4) and is quadrangle and link together by two groups of bearing pins and slide (3).
2, ladder behind the special-purpose vehicle of oil field according to claim 1 is characterized in that at the terminal fixing bumper block of being made by elastomeric material (1) of slide rail (1).
3, ladder behind the special-purpose vehicle of oil field according to claim 1 is characterized in that connecting two groups of bearing pins that change ladder (4) and slide (3), and one group of bearing pin rotates, and another is organized bearing pin and slides in slide bearing pin chute.
4, ladder behind the special-purpose vehicle of oil field according to claim 1 is characterized in that slide (3) and the pedal that changes on terraced (4) are the flute profile anti-skid structure.
