Abstract

The utility model provides an automatic boarding ladder which comprises a main ladder. A scissor-shaped folding ladder and an unfolding device are arranged in the main ladder. The scissor-shaped folding ladder comprises two movable ends, and the unfolding device can unfold the scissor-shaped folding ladder. The unfolding device comprises a first pushing rod, a second pushing rod and a sliding rail; the second pushing rod is horizontally arranged below the inner side of the main ladder, the root part of the first pushing rod is connected with the inner top part of the main ladder, the pushing end of the first pushing rod is connected with one movable end of the scissor-shaped folding ladder, and the movable end is also connected with the pushing end of the second pushing rod by a connecting rod; and the other movable end of the scissor-shaped folding ladder is connected with the main ladder in a rotary manner. The automatic boarding ladder is generally used on a civil air defense mobile-command communication vehicle; the automatic boarding ladder adopts electric control one-key type operation; and the effect is good. The ladder not only solves the problem that the simple boarding ladder is inconvenient to be taken and used, but also solves the problem that steps of a foreign electric ladder are not enough; the automatic boarding ladder can effectively satisfy the requirement for safe boarding of personnel; the ladder is beautiful and elegant, the operation is simple, and the performance is reliable.

Description

Automatically step on companion-way

Technical field

The utility model relates to a kind of ladder of ascending a height, particularly a kind of companion-way of stepping on automatically.

Background technology

General shelter is contained in and carries on the car, the work of not getting off, and at this moment threshold is apart from ground about 1.4 meters high, steps on nearly 2 meters long of companion-way, and ladder is simple and easy and the gradient is bigger, is not up and down very safe.Step on companion-way and be collected at ordinary times in the tailstock ladder box, need to step on the companion-way taking-up when personnel enter the cabin and be installed in hatch door lower draw-bar place, take inconvenience.

Some electronic ladders are abroad arranged at present, but generally have only two to step on, step on to three at most, all the other several stepping on all are made in the cabin, have taken usage space comparatively valuable in the shelter, and the electronic ladder of import costs an arm and a leg, and safeguard also comparatively complicatedly.

The utility model content

Goal of the invention: technical problem to be solved in the utility model is at the deficiencies in the prior art, provide a kind of safe, reliable and convenient launch or collection step on companion-way automatically.

Technical scheme: the utility model provides a kind of companion-way of stepping on automatically, comprises main ladder, is provided with scissor attic ladder that comprises two movable ends and the expanding unit that the scissor attic ladder can be launched in main ladder.

In the utility model, preferably, described expanding unit comprises first push rod, is horizontally set on second push rod and the slide rail of side-lower in the main ladder; The first push rod root is connected with main terraced inside top, and the promote-side of first push rod is connected with a movable end of scissor attic ladder, and this movable end also is connected with the promote-side of described second push rod by a pipe link; Another movable end of described scissor attic ladder is rotaryed connection with slide rail.

In the utility model, preferably, described first push rod and second push rod are electric pushrod, thus motion of sensitive control push rod.

In the utility model, preferably, the root of described first push rod is connected by positioning seat and locating dowel pin with main terraced inside top.

Beneficial effect: the companion-way of stepping on automatically described in the utility model generally uses on the motor-driven command communication car of people's air defense, adopts automatically controlled operating in a key, and is respond well.This ladder has solved the simple and easy companion-way of stepping on and taken inconvenient problem, has solved external electronic ladder simultaneously and has stepped on the not enough problem of number, can satisfy the demand that personal security is stepped on the cabin effectively, and is elegant in appearance, simple to operate, dependable performance.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is done further and to be specified.

Fig. 1 is the expansion drawing that the utility model is stepped on companion-way automatically.

Fig. 2 is that the utility model is stepped on companion-way collection figure automatically.

The specific embodiment

As shown in Figure 1, a kind of companion-way of stepping on automatically of the utility model comprises main ladder, is provided with scissor attic ladder 2 that comprises two movable ends and the expanding unit that scissor attic ladder 2 can be launched in main ladder 1.Described expanding unit comprises first push rod 3 and is horizontally set on second push rod 4 and the slide rail 11 of side-lower in the main ladder; First push rod, 3 roots 8 are connected with main terraced 1 inside top, and the promote-side of first push rod 3 is connected with a movable end 9 of scissor attic ladder 2, and this movable end 9 also is connected with the promote-side 10 of described second push rod 4 by a pipe link 5; Another movable end 12 of described scissor attic ladder 2 is rotaryed connection with slide rail 11.Described first push rod 3 and second push rod 4 are electric pushrod.The root 8 of described first push rod 3 is connected by positioning seat 6 and locating dowel pin 7 with main terraced 1 inside top.

Attic ladder adopts scissors fork-shaped formula, is collected in the main ladder.As shown in Figure 1, utilize second push rod and slide rail that whole ladder is released down by carrying chassis, after putting in place during expansion, provide the signal that puts in place by sensor, second push rod quits work, and first push rod is started working, and attic ladder is outwards launched from main ladder is inner, sensor provides the signal that puts in place, first push rod quits work, and at this moment attic ladder launches to put in place, support ground, attic ladder bottom, play certain supporting role, guarantee the stable of ladder.

As shown in Figure 2, the whole companion-way of stepping on automatically is collected under year chassis of communication truck hatch door below at ordinary times.During collection, utilize first push rod earlier attic ladder to be collected to main ladder, sensor provides the signal that puts in place, and first push rod quits work, and second push rod is started working, and whole ladder is retracted to carries under the chassis, and sensor provides the signal that puts in place, and second push rod quits work.

Electric control part described in the utility model is divided into this area general-duty technology.

The utility model provides a kind of thinking and method of stepping on companion-way automatically; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
