Abstract
The utility model discloses a carriage with a foldable extension ladder, which comprises a carriage body, a track, the foldable extension ladder, a sliding seat, pulleys and a ladder hinged shaft, and is characterized in that the foldable extension ladder is a four-bar mechanism comprising a ladder rod, a ladder pedal and a pedal hinged shaft, and the ladder pedal and the ladder rod are movably connected with by the pedal hinged shaft. The foldable extension ladder is movably connected with the sliding seat by the ladder hinged shaft; the pulleys are arranged on the foldable extension ladder and the sliding seat; and the track is arranged at the top of the carriage body. Under the joint positioning of the pedal hinged shaft and the ladder hinged shaft, the foldable extension ladder can realize translational folding, and the folded foldable extension ladder and the sliding seat can do reciprocating linear sliding in the track under the supporting and rolling action of the pulleys, thus enabling the foldable extension ladder to be conveniently contained in the track of the carriage body or the be drawn out for use from the track of the carriage body. In the utility model, the design height of the carriage with the ladder can be lowered, thus meeting the using requirements when the height space of the carriage with the ladder is limited, and having simple and reasonable structure, and reliable working.
Description
Technical field:
The present invention relates to a kind of made things convenient for personnel band tower wagon railway carriage or compartment up and down that is used on the vehicle, especially relate to a kind of compartment with the folding retractable ladder.
Background technology:
The ladder great majority of the present vehicle are fixing not folding, some folding ladder is the simple chain activity, it is folding to do folding round single-point, such ladder can satisfy operating needs generally speaking, but in particular cases at some, have in limited time as the height of wagon space, the simple chain attic ladder just can't satisfy operating needs.
Summary of the invention:
Defective and deficiency at prior art of the present invention, provide a kind of can be with the compartment of folding retractable ladder, the folding retractable ladder can realize that translation is folding, the operating needs the when height space that satisfies band tower wagon railway carriage or compartment is restricted.
For achieving the above object, the technical solution used in the present invention is:
A kind of compartment with the folding retractable ladder, comprise compartment envelope, track, folding retractable ladder, cliding seat, pulley and terraced hinge, it is characterized in that: described folding retractable ladder comprises terraced bar, terraced pedal and pedal hinge for four-bar linkage, and terraced pedal and terraced bar flexibly connect by the pedal hinge.
Described folding retractable ladder and cliding seat flexibly connect by terraced hinge, and folding retractable ladder and cliding seat are equipped with pulley, and track is arranged on the compartment car top, and track design is the U-shaped structure.
The pulley of installing on the described cliding seat can be a pair of or how right, generally installs many to pulley.
The pulley of installing on the described folding retractable ladder can be a pair of or how right, generally installs many to pulley.
The present invention can be so that the design height in band tower wagon railway carriage or compartment reduces, operating needs when the height space in satisfied band tower wagon railway carriage or compartment is restricted, and the track that can be accommodated in the compartment envelope easily is interior or pull out use from the track of compartment envelope, and is simple and reasonable, reliable operation.
Description of drawings:
Fig. 1 is the not structural representation of folded state of the present invention.
Fig. 2 be among Fig. 1 A to enlarged diagram.
Fig. 3 is the folding but enlarged diagram of receiving state not of the present invention.
Fig. 4 is the enlarged diagram of the folding and receiving state of the present invention.
The specific embodiment:
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1, Fig. 2, this specific embodiment comprises compartment envelope 1, track 2, pulley 3, cliding seat 4, terraced hinge 5 and folding retractable ladder 6.Folding retractable ladder 6 and cliding seat 4 flexibly connect by terraced hinge 5, folding retractable ladder 6 and cliding seat 4 are equipped with pulley 3, track 2 is arranged on the top of compartment envelope 1, folding retractable ladder 6 is a four-bar linkage, comprise terraced bar 61, terraced pedal 62 and pedal hinge 63, terraced pedal 62 and terraced bar 61 flexibly connect by pedal hinge 63.
Referring to Fig. 1, Fig. 3, Fig. 4, the folding retractable ladder 6 before folding and the 90 °＜θ of angle of cliding seat 4 end wises＜180 °, under the common location of pedal hinge 63 and terraced hinge 5, folding retractable ladder 6 can rotate around terraced hinge 5, the realization translation is folding, the folding retractable ladder 6 after folding and angle theta=180 of cliding seat 4 end wises °, and the size on the depth direction reduces, thereby make the design height of track 2 correspondingly to reduce, the design height of compartment envelope 1 reduces, the operating needs the when height space that satisfies compartment envelope 1 is restricted.Under the supporting and rolling action of pulley 3, folding retractable ladder 6 and cliding seat 4 can be made linear slide back and forth in orbit, pull out use thereby make the folding retractable ladder can be accommodated in easily in the track 2 of compartment envelope 1 or from the track 2 of compartment envelope 1.
Above-described specific embodiment only is preferred embodiment of the present invention, and the equivalent arrangements that all acts are done according to the present patent application claim is technology of the present invention and contains.
