The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, mortar folding ladder for automobile of the present utility model comprises and is fixed in the cat ladder of adorning on 92 that the lower end of cat ladder 2 is equiped with turns over hanging ladder 1, and it is hinged and can turn to and cat ladder 2 position overlapped places around pin joint to turn over hanging ladder 1 and cat ladder 2.After breaking away from, can the extension of hanging ladder expansion as cat ladder will be turned at mortar vehicle traction headstock, personnel get on and off with handled easily, can eliminate safe hidden trouble, and again can be upwards folding with turning over hanging ladder after using, it is little that it is taken up room, and can not hinder the installation of traction headstock.
In the present embodiment, cat ladder 2 is installed on by mount pad 4 and adorns on 9.It is hinged with cat ladder 2 lower ends to turn over hanging ladder 1, turns over hanging ladder 1 and comprises two side plates that are oppositely arranged 12 and be installed between two side plates 12 two that pedal 11 is installed in the rear portion of side plate 12 with upper footboard 11, it can not hindered turn over the folding of hanging ladder 1.Side plate 12 upper ends and cat ladder 2 lower ends are hinged by bearing pin 5, offer waist shape installing hole 7 on side plate 12 or the cat ladder 2, and bearing pin 5 is arranged in the waist shape installing hole 7, and the direction that waist shape installing hole 7 is arranged is consistent with the arranged direction of side plate 12.Waist shape installing hole 7 is set, can conveniently turns over the upper and lower motion of hanging ladder 1, make its expansion and folding smooth and easy convenience.Cat ladder 2 is provided with baffle plate 6, and under the deployed condition of turning over hanging ladder 1, baffle plate 6 can play restriction and turn over the effect that hanging ladder 1 rotates, to prevent that turning over hanging ladder 1 rocks backward.
In the present embodiment, turn over to be provided with between hanging ladder 1 and the cat ladder 2 and be used for locking the overlapping locking component that turns over hanging ladder 1 and cat ladder 2 overlap conditions.This overlapping locking component comprises lock groove 8 and locking pin 3, and lock groove 8 is located on the side plate 12, and locking pin 3 is located at the position of matching with lock groove 8 on the cat ladder 2.Perhaps, locking pin 3 is located on the side plate 12, and lock groove 8 is located at the position of matching with locking pin 3 on the cat ladder 2.In the present embodiment, lock groove 8 is L-shaped, and the vertical slots length of lock groove 8 is shorter than the length of waist shape installing hole 7, be that the movement travel of locking pin 3 in lock groove 8 is less than the movement travel of bearing pin 5 in waist shape installing hole 7, when folding when turning over hanging ladder 1, turn over hanging ladder 1 and move downward under action of gravity, each lock groove 8 gets final product mutual locking with locking pin 3, to realize turning over the overlapping locking of hanging ladder 1 and cat ladder 2.
Using method:, be located at all with lock groove 8 and waist shape installing hole 7 that to turn on the hanging ladder 1 be example referring to Fig. 5, Fig. 6 and Fig. 7.When needs will turn over that hanging ladder 1 is upwards folding to be lock onto on the cat ladder 2, upwards rotate around bearing pin 5 with hand steered the hanging ladder 1 that turns over, turn to when parallel when turning over hanging ladder 1 with cat ladder 2, upwards lift and turn over hanging ladder 1, make and turn over hanging ladder 1 and move upward, make that turning over lock groove 8 on the hanging ladder 1 hangs on the locking pin 3 on the cat ladder 2, turns over hanging ladder 1 and moves downward at action of gravity lower edge lock groove 8 and waist shape installing hole 7 after loosing one's grip along waist shape installing hole 7, lock groove 8 will buckle on locking pin 3, will turn over hanging ladder 1 locking.Equally, use when turning over hanging ladder 1, also upwards lift and turn over hanging ladder 1, make and turn over hanging ladder 1 and move upward, the lock groove 8 that turns on the hanging ladder 1 is withdrawed from locking pin 3, can will turn over hanging ladder 1 upset downwards and come into operation along waist shape installing hole 7 at needs.
As shown in Figure 8, mortar vehicle of the present utility model, comprise chassis 10 and be installed on the chassis 10 on adorn 9, be equiped with above-mentioned folding ladder in last 9 the front side adorned.It can effectively solve the traction headstock and break away from the problem that the back operating personnel get on or off the bus and require great effort, and can eliminate safe hidden trouble.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite all should be considered as protection domain of the present utility model.
