The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The sketch map of a kind of automobile-used moveable cart ladder of the utility model in deployed condition has been shown among Fig. 1.This mobile ladder comprises ladder 1; Towards the surface of car body, just inner surface is provided with upper connector 4 and following connector 7, on the car body of fire fighting truck at the handrail of ladder 1 both sides; Be fixed with and be used for fixing the upper fixing element 2 and following fixture 5 that supports ladder 1; Also have the upper pendulum bar 3 and draft link 6 of interconnect function between ladder 1 and fixture, first end of upper pendulum bar 3 rotatably is connected on the upper fixing element 2, and second end rotatably is connected on the upper connector 4; First end of draft link 6 rotatably is connected down on the fixture 5, and second end rotatably is connected down on the connector 7.Because used the setting of upper connector 4 and following connector 7, fork no longer directly is connected the side of ladder 1, but can be connected inner surface, so also just avoided fork with terraced grade between conflict.
The sketch map of ladder 1 at retracted state has been shown among Fig. 2, and in this embodiment, following fixture 5 is provided with locking piece, and draft link 6 is provided with and the corresponding locking bit of locking piece.Preferably, locking piece is a flexible lock pin 8, and locking bit is a lockhole 9.Before the fire fighting truck ladder work did, ladder 1 was in retracted state.When the fire fighting truck ladder work did, the flexible lock pin 8 under the Unscrew on the fixed block 5 broke away from ladder 1 and flexible lock pin 8, stresses on both hands outstanding ladder 1 to drop-down, and upper pendulum bar 3 rotates respectively with draft link 6, and ladder 1 is launched.After work is accomplished, receivable carriage return ladder.Upper pendulum bar 3 rotate respectively with draft link 6, and to ladder 1 during near the upright position, in the lockhole 9 of two draft links 6, ladder 1 was firmly locked about two flexible lock pins 8 inserted it into about rotation.Receive the effect of spring force, the vibration influence when flexible lock pin 8 can not receive vehicle ' and withdrawing from has guaranteed the safety of fire fighting truck ladder when vehicle '.Another is embodiment preferably, and flexible lock pin 8 can be replaced by snap lock ancient unit of weight, equal to 1/24 liang, and the lockhole 9 in the draft link 6 is replaced by the lock hole simultaneously.Like this, be to lock between fixture and the movable part, the more reliable and insurance than locking between the movable part of the prior art.
The front schematic view of moveable cart ladder has been shown among Fig. 3; Show in the present embodiment; Upper connector 4, following connector 7, upper fixing element 2, following fixture 5, upper pendulum bar 3 and draft link 6 these parts respectively are provided with at least one in the both sides of ladder 1 respectively; Constitute paired braced structures, secure like this.Correspondingly, flexible lock pin 8 also is paired layout with lockhole 9.
Show upper pendulum bar 3 and the sketch map of draft link 6 under the deployed condition among Fig. 4 and Fig. 5 respectively.In this embodiment, upper pendulum bar 3 and draft link 6 all are the rod members that second end that is connected with connector has kink.This kink is in order to form a lock face; When ladder 1 launches to put in place; When lock face arrived Fig. 4 and latched position shown in Figure 5, two lock faces contacted with the surface towards car body of ladder 1 simultaneously, reach locking action; Upper pendulum bar 3 and draft link 6 can't be moved again, this moment fire fighter's ladder of getting on or off the bus.Gravitate, fire ladder are in the dead-centre position all the time, and the fireman is safety up and down.Because last draft link all contacts with ladder 1, and two dead-centre positions are just arranged up and down, locks more reliable than single dead point of the prior art.
As one preferred embodiment, upper pendulum bar 3 rotatably is connected with upper connector 4 with upper fixing element 2 respectively through bearing pin; Draft link 6 rotatably is connected with following connector 7 with following fixture 5 respectively through bearing pin.Using bearing pin to carry out rotatable connection is a kind of simple and easy to do design.
According to the mobile ladder of the utility model, have following beneficial effect:
One, upper and lower fork does not occupy terraced stall space, can arrange arbitrarily according to the car body situation;
Two, can draw back the permanent position of upper and lower fixture, constant spacing increases, the ladder good stability, and the fire fighter is safer up and down;
Three, flexible lock pin is fixed on down on the fixture, locks in the lockhole through flexible lock pin insertion draft link when locking, is to be locked to movable draft link by fixing following fixture to reach the purpose that is locked to ladder the more reliable and insurance of such locking;
Four, two dead-centre positions are arranged, it is more firm to lock;
Five, upper and lower swing rod structure is simple, makes easily.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
