The non-self-unloading autotruck of Fig. 1 BI car load unloading machine structure principle chart.
The utility model is further described with embodiment below in conjunction with accompanying drawing:
This unloading machine mainly is made up of carrier loader platform and two two parts of fluid pressure drive device.Its constructional feature and mounting condition are seen shown in Figure 1.
Carrier loader platform comprises that platform 1, resistance trochus 16, turning joint 15 and safety hook-chain 17 constitute.Platform 1 forms for shaped steel weldering system, and when being fully loaded with zero load with the maximum gross car during design, the combination of different loads calculates internal force, determines its structural shape, has enough strength and stiffness.Its scantling of structure is 6410 * 2900mm.Resistance trochus 16 adopts welded steel plate, is directly welded in the tail end of platform 1, becomes one with it.For increasing the friction force between automobile and the resistance trochus, lay one deck rubber at the contact surface place of resistance trochus and wheel.The height of resistance trochus is 420mm, is equivalent to the radius of motor tire, can stop the back row of automobile fully.Turning joint 15 is to be combined by cast steel rocker bar bearing and alloy steel bearing pin.Centre-of-gravity displacement during according to platform deadweight and automobile heavy duty changes, and the position of turning joint is located at apart from the resistance trochus and is hindered tire line of centers 1410mm place.On platform, the other end is fixed on the reinforced beam of special setting rocker bar bearing one end with bolt.For preventing that automobile from crossing the position because of platform inclination, and throw away carrier loader platform, cause the accident, at the platform front end safety hook-chain 4 is set and hangs mutually with automobile front beam.
Fluid pressure drive device is the propulsion source that carrier loader platform fascinates, and mainly is made up of hydraulic actuating cylinder 13 and Hydraulic Station two parts.Hydraulic actuating cylinder is the single-piston rod two-way cylinder, and two ends are the loose-joint butt seat.Be installed on the below of carrier loader platform, apart from turning joint seat 2150mm place, the upper end hinge is connected with carrier loader platform with bolt, and lower end hinge and concrete foundation are fixed.Hydraulic Station is made up of fuel tank, oil pump, electrical motor, instrument and various control cock.The each several part components and parts all are arranged on the fuel tank, combine with hydraulic manifold block, are placed between terrestrial operation.Between hydraulic ram and the Hydraulic Station, adopt the high-pressure rubber pipe 6 of φ 22 * 1.5mm that hydraulic circuit is connected, formed the complete hydrostatic drive of a cover.
The rotation of BI car load unloading machine offload platform is to lean on the action of hydraulic ram to realize that its power hydraulic system as shown in Figure 1.Require stable working when platform fascinates, speed is even, and can stop on arbitrarily angled.After the automobile unloading, platform returns by deadweight and oil cylinder backhaul application force and finishes, and speed is even when requiring to return.In design during this machine hydraulic system, in order to satisfy above-mentioned every requirement simultaneously, and help heat radiation, the platform major loop that fascinates has adopted piston cylinder formula balance and block sytem, and its principle of work is as follows:
After automobile enters platform and comes to a complete stop, at first safety hook-chain is hung up properly, and open the automobile drop end.Energized then starts the electrical motor 5 of oil pump 4.At this moment, M type 3-position 4-way hand change over valve 3 is in meta, and pressure oil enters the P chamber, comes out from 0 chamber, directly gets back to fuel tank 7, and hydraulic actuating cylinder 13 no pressure oils enter and do not do any action.When the moving change-over valve handle of operating personal plate, when change-over valve 3 was in right, pressure oil entered the P chamber and comes out from the A chamber, and the check valve of washing open in the balance cock 2 enters the hydraulic actuating cylinder cavity of resorption, and oil return is unimpeded, enters the B chamber and comes out from 0 chamber, directly gets back to fuel tank.At this moment, hydraulic cylinder piston rod rises, and promotes carrier loader platform 1 and rotates.When carrier loader platform and automobile tilted to certain position together, coal just can slip into from automobile and be subjected to coal bunker, reaches the discharged purpose of automobile.After unloading is finished, when automobile and platform reset, change-over valve 3 is got to position, a left side, pressure oil enters the P chamber and comes out from the B chamber, enters the C chamber of the epicoele and the balance cock 2 of oil cylinder.At this moment, the balance cock locking, hydraulic actuating cylinder can not oil return, and hydraulic cylinder piston rod is motionless, and automobile and platform are supported, and can not reset.When oil pump 4 continued pump oil, when pressure was elevated to setting, the control spool in C chamber made main valve open, makes cavity of resorption be able to oil return, and automobile and platform begin to descend.When fuel feeding had little time if descending speed is too fast, the C cavity pressure descended, and main valve plug is tending towards closing direction, increased the meter out effect, and automobile and platform descending speed slow down.Hydraulic cylinder piston rod just slowly shrinks like this, up to getting back to original position again, finishes once unloading action.
When unexpected power failure, automobile and platform suspend in mid air, and cisco unity malfunction is opened shutoff valve 12 this moment, makes hydraulic actuating cylinder cavity of resorption oil directly get back to fuel tank 7, and automobile and platform are put back into original position.
When if hydraulic actuating cylinder 13 bears outer load increase; the delivery pressure of oil pump 4 raises; when surpassing specified value; automatically open by pass valve 9; the oil that oil pump is discharged is got back to fuel tank 7 from by pass valve; system pressure can not continue to raise, thereby the safety guard-safeguard effect is played in protection oil pump and the unlikely damage of other components and parts.
