Description

Vehicle telescopic ladder
Technical field
The utility model belongs to ladder technical field, is specifically related to a kind of ladder be arranged on vehicle.
Background technology
Along with raising and the economic fast development of people's living standard, auto trade is particularly evident, and particularly caravan or semi-mounted boxed truck also progress into the visual field of people, are widely used.Pass in and out these higher box vehicles and just use ladder.Modal situation is, ladder, for being fixed on vehicle, such as, is welded on the steel plate on vehicle chassis guardrail or storage battery, fuel tank.This foot of stairs tread is narrow, and stair diff-H is larger, and safety is inadequate, and people needs when getting on the bus to buttress vehicle body, can not carry weight or remove thing, and this fixed type stair due to exposed at side portion of vehicle, also affect vehicle to a certain extent attractive in appearance.Also have a kind of situation to be that ladder is the ladder sections independent of vehicle, when needing to use ladder, manually ladder moved down car and come on vehicle, when not needing to use ladder, then with manually ladder being moved on vehicle.This ladder not only takies inner space, and needs manually to shift from one place to another, and wastes time and energy.
Summary of the invention
Technical problem to be solved in the utility model is the shortcoming overcoming existing vehicle ladder, provides a kind of vehicle telescopic reasonable in design, that structure is simple, easy to use terraced.
Solving the problems of the technologies described above adopted technical scheme is: erecting frame is arranged on car chassis, the adapter plate of erecting frame is processed with rail groove a in left-right direction that arrange from top to down, rail groove b, rail groove c, the adapter plate of rail groove a installed in front frame is provided with location hook, expansion bracket is provided with in rail groove b before and after erecting frame on the adapter plate of both sides and rail groove c, the both sides, front and back of expansion bracket are provided with the tommy be arranged in rail groove a, the upper flexible pin of peace Installed in rail groove b, the lower flexible pin of peace Installed in rail groove c, the upper end of swing arm is arranged on the bearing pin of expansion bracket, lower end is processed with slotted eye and is arranged on erecting frame by bearing pin, the push rod hinge of electric pushrod is arranged in the middle part of swing arm, the motor hinge of electric pushrod is rack-mount, Bracket setting is on car chassis.
Rail groove a of the present utility model and rail groove b is horizontal rail, and the line of centers of rail groove a parallels with the line of centers of rail groove b, and rail groove c is for being bent downwardly track.
The right-hand justified of rail groove a of the present utility model and rail groove b, the length of rail groove a is the half of rail groove b length.
Expansion bracket of the present utility model is: on the bracing frame of the diamond structure be hinged, be provided with the horizontal stretcher that is parallel to each other.
Because expansion bracket of the present utility model adopts on the rhombic supporting frame be hinged, stretcher is set, the adapter plate of erecting frame is processed with 3 road rail grooves in left-right direction, rhombic supporting frame can slide along 3 road rail grooves, expansion bracket is slided along 3 road rail grooves, realizes expansion bracket and stretch out under car chassis or retract.The utility model has reasonable in design, flexible flexible, steady safety, saves the advantages such as space, can bear personnel's getting on-off automobile of 200kg, can use on higher box vehicle.

Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is contraction state figure in the utility model use procedure.
Fig. 4 is the structural representation of expansion bracket 1 in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but the utility model is not limited to these embodiments.
Embodiment 1
In Fig. 1,2,3, the vehicle telescopic ladder of the present embodiment is made up of expansion bracket 1, tommy 2, lower flexible pin 3, upper flexible pin 4, electric pushrod 5, support 6, fork 7, erecting frame 8, location hook 9 connection.
Erecting frame 8 screw threads for fastening connector is fixedly mounted on the chassis of automobile, the adapter plate of erecting frame 8 is processed with rail groove a in left-right direction, the below of rail groove a is processed with rail groove b, the below of rail groove b is processed with rail groove c, rail groove a is used for balance, rail groove a and rail groove b is horizontal rail, and the line of centers of rail groove a and rail groove b is parallel to each other, and rail groove c is for being bent downwardly track.The right-hand justified of rail groove a and rail groove b, the length of rail groove a is the half of rail groove b length.The adapter plate of the installed in front frame 8 of rail groove a is installed with location hook 9 with screw threads for fastening connector.In rail groove b on the adapter plate of the both sides, front and back of erecting frame 8 and rail groove c, expansion bracket 1 is installed, the both sides, front and back of expansion bracket 1 are provided with tommy 2, lower flexible pin 3, upper flexible pin 4, tommy 2 is arranged in rail groove a, upper flexible pin 4 is arranged in rail groove b, lower flexible pin 3 is arranged in rail groove c, can realize expansion bracket 1 like this and stretches downwards left along rail groove b and rail groove c or upwards retract to the right.
The upper end of swing arm 7 is arranged on the bearing pin of expansion bracket 1, swing arm 7 can rotate around the bearing pin of expansion bracket 1, the lower end of swing arm 7 is processed with slotted eye and is arranged on erecting frame 8 by bearing pin, the push rod hinge of electric pushrod 5 is arranged in the middle part of swing arm 7, the motor of electric pushrod 5 is installed on the frame 6 by hinge, and support 6 screw threads for fastening connector is fixedly mounted on car chassis.When the push rod of electric pushrod 5 stretches out, swing arm 7 swings and is pulled out by expansion bracket 1, slips in location hook 9 when tommy 2 moves to the high order end of rail groove a, and location hook 9 pins fixing for tommy 2.When packing up expansion bracket 1, operating personal opens location hook 9, the pusher retracted of electric pushrod 5, drives swing arm 7 by expansion bracket 1 inverse motion, is regained by expansion bracket 1.
