The specific embodiment
As shown in Figure 1, 2, 3, superimposed trailer comprises vehicle frame 10, the one end below of vehicle frame 10 is provided with sprung-hub wheel 11, there is passive supporting leg 12 other end below, sprung-hub wheel 11 plays the effect of supporting superimposed trailer and lade part weight, when tractor truck takes off extension, supporting leg 12 works to support trailer and lade part weight in the superimposed trailer front, on vehicle frame 10 front ends at these supporting leg 12 places the towing pin 13 that links to each other with towing vehicle is arranged, be connected with tractor truck, transmission travels superimposed trailer and tractor truck from the tractive force of tractor truck simultaneously.Being provided with support body 20 above the described vehicle frame 10, is the parts of installing, place main equipment or super wide plate material 70, and a side and the vehicle frame 10 of support body 20 are hinged, are provided with the lifting falling unit between opposite side and the vehicle frame 10.
As shown in Figure 1, 2, 3, described jacking system is an oil cylinder 30, the lateral wall of oil cylinder 30 cylinder bodies and vehicle frame 10 is hinged, the bottom-hinged of the upper end of oil cylinder 30 piston rods and the close side of support body 20, and the opposite side of support body 20 is provided with and is used to limit and the fixing limiting stopper 40 of as ready object.
As shown in Figure 1, described oil cylinder 30 equidistantly is provided with 2～6 along the length direction of support body 20, and uniform lifting power can be provided like this, and limiting stopper 40 equidistantly is provided with 2～6 along the length direction of support body 20, helps stably fixedly as ready object.
As shown in Figure 1, 2, 3, described vehicle frame 10 is that two ends height, stage casing are recessed flat-shaped, support body 20 is positioned at recessed flat-shaped stage casing, vehicle frame 10 adopts the tenon riveting structure, so that reduce the bottom-to-top-height after the loading as much as possible, be provided with the support 50 that support body 20 is supported on tilting state between the bottom of described support body 20 and the vehicle frame 10.After elevating ram 30 promotes support body 20 inclination certain angles, with support 50 support body 20 is propped, to prevent that leakage of hydraulic system causes support body 20 to fall voluntarily in the vehicle ' process.
Shown in Fig. 2,3, described oil cylinder 30 cylinder bodies are hinged by the bearing 14 of the lateral wall setting of gudgeon and vehicle frame 10, are the terrain clearance that improves elevating ram 30 bottoms, and elevating ram 3 adopts multistage telescoping structure, i.e. telescopic rams.The opposite side of support body 20 has bearing 21 hinged by bearing pin with the bearing 15 of vehicle frame 10 homonymies.
Shown in Fig. 2,3, described limiting stopper 40 slightly protrudes in the upper surface of support body 20, rectangular tube 41 is arranged at the bottom of limiting stopper 40, in conjunction with Fig. 4, rectangular tube 41 constitutes mobile cooperation of pegging graft with the rectangular tube 22 that the lateral wall portion of support body 20 is provided with, rectangular tube 22 is provided with along the plane of support body 20 and is vertical with its lateral wall, has locating dowel pin 60 to be connected on the inserting section of rectangular tube 41 and rectangular tube 22.Rectangular tube 22 can be the crossbeam of support body 20, and the hole of pegging graft for locating dowel pin 60 is provided with a plurality of so that regulate, and according to the difference of sheet material 70 width, behind the diverse location with limiting stopper 40 insertion rectangular tubes 22, uses locating dowel pin 60 with limiting stopper 40 lockings.
Below in conjunction with working process the utility model is further described:
Before the loading, support body 20 drops on the vehicle frame 10 and is the level of state.According to the difference of sheet material 70 width, behind the appropriate location with rectangular tube 22 on the limiting stopper 40 insertion support bodys 20, limiting stopper 40 is locked with locating dowel pin 60.After super wide plate material 70 adopts special-purpose hanging device entrucking, one side make sheet material 70 be close to limiting stopper 40, and sheet material 70 is fixed on the support body 20 by suitable fixed form.Operating hydraulic efficiency pressure system then rises hoist cylinder 30, make sheet material 70, support body 20 relative vehicle frames 10 tilt to have a certain degree, again 50 on support is put into the position of setting on the vehicle frame 10, the operation hydraulic efficiency pressure system, support body 20 is fallen, after support 50 stably supports support body 20, the operation of stop solution pressing system.With steel wire cable sheet material 70 and support body 20 are strained with vehicle frame 10 together at last, caused support 50 displacements to prevent the pounding of vehicle in the transportation.
During unloading, steel wire cable is pulled down, the operation hydraulic efficiency pressure system after one section of hoist cylinder 30 rise, is removed support 50.Operate hydraulic efficiency pressure system once more, hoist cylinder 30 is fallen.Remove the sheet material 70 that is fixed at last, adopt special-purpose hanging device that sheet material 70 is unloaded.
