As shown in Figure 4, described steering hardware 4, by connecting and contain the finger transfer device 4.1 of two fingers with the trac. head, pass through bearing pin 4.6 pivotally attached swing arms 4.2 with car body 3, with two connecting rods 4.3 of swing arm front end difference pivotally attached, two steering swivels 4.4 that connect with two connecting rod other ends respectively constitute.The front and back position that is positioned at bearing pin 4.6 in the swing arm has preceding chute 4.2.2, back chute 4.2.1, and the preceding finger 4.1.2 of finger transfer device can insert preceding chute 4.2.2, chute 4.2.1 after back finger 4.1.1 extracts out simultaneously; Or back finger 4.1.1 can insert back chute 4.2.1, chute 4.2.2, conversion mutually before simultaneously preceding finger 4.1.2 extracts out.
As shown in Figure 5, described finger transfer device 4.1, the crank levers 4.1.4 that is slided up and down by finger seat 4.1.3, preceding finger 4.1.2, back finger 4.1.1 and drive finger forms.Finger seat 4.1.3 and the base 4.1.5 that is fixed in the trac. head in advance pass through Bolt Connection, crank levers 4.1.4 is hinged with the supporting 4.1.6 that is fixed on finger seat 4.1.3 middle part, crank levers 4.1.4 is driven through pull bar leverage 4.1.8 and bullet school 4.1.9 by the handle 4.1.7 that is arranged on the driver operation position.When plate fixed handle 4.1.7, can drive crank levers 4.1.4 by pull bar leverage 4.1.8 and spring 4.1.9 and swing back and forth, can make two fingers from the preceding chute 4.2.2 of swing arm 4.2 or back chute 4.2.1, insert or extract out, conversion mutually.
(referring to Fig. 3) as shown in Figure 4, two steering swivels 4.4 of described steering hardware, it respectively has a vertical hinge 4.4.3 to connect with two steering swivel free bearings 3.2 of Vehicular body front respectively, each steering swivel has two horizontal limb arms, a limb arm 4.4.1 connects with swing arm 4.2 by connecting rod 4.3, and another limb arm 4.4.2 goes up wheel 4.5 is installed.
(referring to Fig. 1,4,5) as shown in Figure 3, car body is a steel structure, top is that a coupling seat 3.1 is used bolted connection with the base 5.1 of equipment; Front part sides is a steering swivel free bearing 3.2, is used to install the vertical hinge 4.4.3c of the steering swivel 4.4 of steering hardware, is bearing on two wheels 4.5 by its trailer; In the middle of the car body bottom swing arm hinged block 3.3 is arranged, be used to install the swing arm 4.2 and the hinge 4.6 thereof of steering hardware; Captiveing joint with right arm 2.2 with left side arm 2.1 respectively in the both sides, rear portion, pulls at tractor rear by pulling crossbeam 1.
(referring to Fig. 1,2) as shown in Figure 9, described hydraulic pressure and control system 6, the hydraulic actuating cylinder or the HM Hydraulic Motor 5.2 that are used for the transmission equipment, can adopt prior art (is example with the loading machine), system comprises Hydraulic Pump 6.2, hydraulic valve (multiple directional control valve) 6.3, pipeline (comprising hard tube, flexible pipe and quick coupling) 6.4 and annex (fuel tank, oil filter etc.) 6.5.Hydraulic Pump can utilize the Hydraulic Pump of trac., connects with hydraulic efficiency pressure system on the engineering trailer with flexible pipe and quick coupling, also Hydraulic Pump and fuel tank can be located at engineering trailer relevant position, links with flexible coupling and tractor motive power output shaft.The manual multi-path reversing valve of hydraulic efficiency pressure system is assembled on the support 6.1, and the control handle of hand valve places the driver to be convenient to operation place.Support 6.1 can be fixed on the engineering trailer, also can adopt easy-to-mount mode to be contained on the trac., connects with hydraulic hose with the engineering trailer.
Shown in Fig. 6,7, when the trac. walking turned to, it and engineering trailer produced a drift angle α, be connected in the finger transfer device 4.1 of trac. head, swing arm 4.2 deflections by finger is stirred the engineering trailer drive steering swivel 4.4 by connecting rod 4.3 and rotate, and turn to thereby drive wheel 4.5.Because trac. advances or head deflecting direction difference when retreating, by driver operation finger transfer device, the position of finger insertion swing arm as shown in the figure, when advancing, back finger 4.1.1 can insert among the chute 4.2.1 of back, when retreating, before preceding finger 4.1.2 can insert among the chute 4.2.2, make and no matter advance or the wheel flutter of the wheel of engineering trailer and trac. can both be by equidirectional deflection when retreating.Turning center coincidence with engineering trailer and trac. is a condition, by calculating the physical dimension of determined swing arm, connecting rod and steering swivel, can make trac. in walking (advance or retreat) when turning to, as long as with one of engineering trailer deflection very low-angle α, just can drive the engineering trailer wheels and turn to by stirring swing arm in company with walking.
As shown in Figure 8, equipment 5 is different and different with engineer operation, and its structure can adopt prior art, operating mechanism's part of promptly similar existing special engineering machinery.As finish that harvesting, loading, excavation, fork fortune, cutter bore, the different engineer operations of lifting, then dispose corresponding work mechanism, form as among the figure: a-harvesting trailer, b-loading trailer, c-fork fortune trailer, d-excavate trailer, e-cutter brill trailer, f-bay-lift trailer, g-lifting trailer.
It is as follows to utilize trac. to pull the step of engineering trailer:
1. unclamp the bolt of engineering trailer side arm afterbody deck 2.3, unload deck, the crossbeam 1 of pulling of engineering trailer is unsnaped with side arm 2;
2. trac. 7 is sailed between engineering trailer two side arms;
3. will pull the free bearing 1.1 and tractor rear traction seat pin joint at crossbeam middle part;
4. will pull crossbeam two ends gudgeon 1.2 and place in the gudgeon groove 2.4 of left and right sides side arm, and deck 2.3 will be enclosed within on the gudgeon, and be fixed by bolts on the side arm;
5. with finger transfer device 4.1 and Rocker arm 4 .2 contraposition, and finger seat 4.1.3 is fixed by bolts on the base 4.1.5 that the trac. head welds in advance;
6. with the hydraulic efficiency pressure system of trac. and the hydraulic efficiency pressure system of engineering trailer, connect with flexible pipe and quick coupling, or, connect with flexible coupling with the power take-off shaft of trac. and the hydraulic pump shaft of engineering trailer.
Trac. can be thrown off the engineering trailer by above-mentioned reverse procedure.
