Slowly climb up flat bed trailer.Since semi-trailer tail height is higher, center of gravity is higher when causing the engineering equipment to get on the bus, stablize compared with
, easily there is danger in difference, and efficiency is not also high.
Utility model content
The purpose of this utility model is the deficiencies in the prior art to be solved, there is provided a kind of engineering equipment is got on the bus stabilization
More preferably, the detachable low flat bed semi trailer of the gooseneck of security higher.
The utility model is achieved through the following technical solutions:
I.e. a kind of detachable low flat bed semi trailer of gooseneck, including vehicle frame and gooseneck, the front end of vehicle frame are fixed with two
Jack panel and two hooks, the gooseneck are equipped with an oil cylinder one, and the piston rod hinge-coupled of oil cylinder one has link, connection
The front end of frame is hinged on gooseneck, and the rear end of gooseneck is equipped with two oil cylinders two and an auxiliary support apparatus, the piston of oil cylinder two
Bar connection has rotating bar, and two oil cylinders two and two rotating bars are, each rotating bars hinged by a long pin shaft
Front end the lower end of gooseneck is hinged on by short pin shaft.
The utility model flat bed trailer center of gravity is lower, and engineering equipment is got on the bus in the front end of vehicle frame, and stability is good, security
Height, efficiency of getting on or off the bus also are improved.
Further preferably, the length of the rotating bar is equal with the distance between jack panel center and hook center.
Further preferably, the vehicle frame front end is hingedly equipped with two cat ladders.
Further preferably, the auxiliary support apparatus is hinged on gooseneck rear end.
Compared with prior art, beneficial effect possessed by the utility model is:
The utility model flat bed trailer center of gravity is lower, and engineering equipment is got on the bus in the front end of vehicle frame, and stability is good, security
Height, efficiency of getting on or off the bus also are improved.

Embodiment
Below against attached drawing, specific embodiment of the present utility model is described in further detail.
The detachable low flat bed semi trailer of a kind of gooseneck as shown in Figure 1 to Figure 3, including vehicle frame 1 and gooseneck 5, vehicle frame 1
Front end is fixed with two jack panels 2 and two hooks 3, and gooseneck 5 is equipped with an oil cylinder 1, and the piston rod of oil cylinder 1 is hinged
Connection has link 7, and the front end of link 7 is hinged on gooseneck 5, and the rear end of gooseneck 5 is equipped with two oil cylinders 28 and an auxiliary
Support device 12, auxiliary support apparatus 12 are hinged on 5 rear end of gooseneck, and the piston rod connection of oil cylinder 28 has rotating bar 9,
Two oil cylinders 28 and two rotating bars 9 are hinged by a long pin shaft 11, and the front end of each rotating bar 9 passes through
Short pin shaft 10 is hinged on the lower end of gooseneck 5, the distance between the length of rotating bar 9 and 3 centers of 2 center of jack panel and hook phase
Deng 1 front end of vehicle frame is hingedly equipped with two cat ladders 4.
The course of work:
It is separable between the gooseneck 5 and vehicle frame 1 of the utility model, when being linked together, long pin shaft 11 is located at two
In jack panel 2, short pin shaft 10 is in two hooks 3, and oil cylinder 1 is in retracted mode, and oil cylinder 28 is in elongation state.Goose
Neck 5 and the separation process of vehicle frame 1 are as follows:Oil cylinder 28 extends, and auxiliary support apparatus 12 is packed up, and then oil cylinder 28 is shunk, goose
5 rear end of neck sinks, and short pin shaft 10 is fallen to the ground with 1 front end of vehicle frame below, and short pin shaft 10 departs from hook 3, and then oil cylinder 1 is stretched
It is long, drive link 7 to rotate, link 7 is fixed on the crossbeam of tractor, is made short pin shaft 10 liftoff slightly below, finally, is led
Drawing car drives gooseneck 5 to advance, and long pin shaft 11 departs from out of jack panel 2, completes separation process, puts down two cat ladders 4, engineering equipment
Vehicle frame 1 can be climbed up.Gooseneck 5 and the connection process of vehicle frame 1 are as follows:Two upsets of cat ladder 4 are placed on vehicle frame 1, are led
Drawing car drives gooseneck 5 to retreat, and long pin shaft 11 is inserted into two jack panels 2, and short pin shaft 10 is moved to the lower section of hook 3 at this time, this
When oil cylinder 28 extend, 5 rear end of gooseneck raises up, vehicle frame 1 is lifted, then puts down auxiliary support apparatus 12, then retract cylinder two
8, allow auxiliary support apparatus 12 to be contacted with vehicle frame 1 finally, oil cylinder 1 is retracted, and completes the connection process between gooseneck 5 and vehicle frame 1.
In the description of the utility model, term " interior ", " outer ", " longitudinal direction ", " transverse direction ", " on ", " under ", " top ", " bottom "
Orientation or position relationship Deng instruction are based on orientation shown in the drawings or position relationship, are for only for ease of and describe this practicality newly
Type rather than require the utility model must be with specific azimuth configuration and operation, therefore it is not intended that to the utility model
Limitation.
