Description
Technical field
This utility model relates to work van field, is the built-in working stand device of a kind of work van.
Background technology
Along with the development of society, various special operation cars also arise at the historic moment, and some special operation car needs staff in operation within a vehicle, and frequency of getting on or off the bus is higher, and personnel need in passing in and out car to use getting-on ladder, and getting-on ladder is safe and reliable.Use fixed marking time, be placed at car door when getting on or off the bus, in-convenience in use, and travel time be put in car in take interior space；Use simple hanging ladder dangerous, security incident easily occurs.
Summary of the invention
The purpose of this utility model is to provide for a kind of built-in working stand of getting on or off the bus, and is packed up by working stand and is hidden in envelope underframe auxiliary girder, and use night bolt locking in vehicle travel process；When parking uses, opening night bolt, working stand pulls out in auxiliary girder placement ground, pedal will be horizontal, and facilitate personnel upper and lower.
The technical solution of the utility model is: the built-in working stand device of a kind of work van, its feature upper supporting leg, lower supporting leg are connected bearing pin, lower supporting leg with upper supporting leg with dolly longeron by supporting leg respectively and are connected bearing pin connection with dolly longeron, pedal is connected bearing pin by pedal and is connected with lower supporting leg with supporting leg, and the quantity of pedal determines according to operation height；Dolly rolling bearing is installed on dolly longeron, lower supporting leg is provided with lower supporting leg rolling bearing, upper supporting leg is provided with night bolt, dolly longeron has track.
Owing to have employed technique scheme, this apparatus structure is simple, can be packed up by working stand and be hidden in bottom envelope, easily pull out when parking uses and put to ground in vehicle travel process, esy to use, safe and reliable.
Accompanying drawing explanation
Fig. 1 is use status architecture schematic diagram of the present utility model.
In the drawings: 1, upper supporting leg；2, lower supporting leg；3, pedal；4, pedal is connected bearing pin with supporting leg；5, lower supporting leg rolling bearing；6, night bolt；7, upper supporting leg is connected bearing pin with dolly longeron；8, dolly longeron；9, lower supporting leg is connected bearing pin with dolly longeron；10, dolly rolling bearing；11, track.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
In FIG, upper supporting leg 1, lower supporting leg 2 are respectively by supporting leg is connected bearing pin 7 with upper supporting leg with dolly longeron, lower supporting leg is connected bearing pin 9 with dolly longeron and connects, pedal 3 is connected bearing pin 4 by pedal and is connected with lower supporting leg 2 with supporting leg, and the quantity of pedal determines according to operation height；Dolly rolling bearing 10 is installed on dolly longeron 8, lower supporting leg 2 is provided with lower supporting leg rolling bearing 5, upper supporting leg 1 is provided with night bolt 6, dolly longeron 8 has track 11.
Dolly rolling bearing 10 is put into rail to 11, lift night bolt 6, during lifting, upper supporting leg 1, lower supporting leg 2 middle ware are away from will automatically reduce, pedal 3 also will be become heeling condition from level, instantly when supporting leg 2 and track 11 are in sustained height, ladder is i.e. in fully closed condition, push away forward ladder, dolly longeron rolling bearing 10 rolls in track 11, lower supporting leg rolling bearing 5 also can be in injection 11 under thrust, after ladder is completely into track, night bolt 6 is ejected, prevent ladder in the process of moving from skidding off.When using ladder, open night bolt 6, hold and draw outside night bolt 6, putting down gently to ground, in dropping process, upper supporting leg 1 is gradually become parastate with lower supporting leg 2 by closed configuration, after upper and lower supporting leg base angle contacts with ground completely, pedal 3 now can will be used safely in perfectly level state.
