The specific embodiment
Referring to Fig. 1, lorry described in the utility model comprises cover cap 1, track 2 and jacking system with telescopic covering.Described cover cap 2 comprises that first lid 3, second are covered 4, third lid 5 and 6, four lids of Ding Gai are made up of lid frame 7 and connected cover plate 8 respectively.See Fig. 2 and 3, described lid frame 7 comprises front-axle beam 9, supports wheel carrier 10, interior support wheel carrier 11, tie-beam 12 and the back rest 13 outward.Described forward and backward beam 9,13 is a chevron pointing, and its angle is 160 °-175 °.See Fig. 5, the described interior wheel carrier 11 that supports is connected with the back rest 13, and upper and lower two support wheels 14,15 are installed on it, and the described outer wheel carrier 10 that supports is connected with front-axle beam 9, and upper and lower two support wheels 16,17 also are installed on it.Tie-beam 12 connects inside and outside support wheel carrier 11,10.See Fig. 3, described cover plate 8 is installed on the forward and backward beam 9,13, and it has top board 18 and side plate 19.See Fig. 6, connect by pull bar 20 between per two lids that the pull bar of first lid 3 passes the centre hole that second is covered 4 tie-beams, the pull bar of second lid 4 passes the centre hole of third lid, 5 tie-beams, and the pull bar of third lid 6 passes the centre hole of fourth lid tie-beam.Rear end (promptly being positioned at an end of the tailstock) at Jia Gai, second lid and the third lid tie-beam 12 has block 21, between block 21 and another tie-beam, compression spring 22 is installed on the pull bar 20, the other end (being front end) at pull bar also has compression spring 23, with convenient pull bar in tie-beam when mobile, reduce to cover with cover between impact and strengthening when contacting shrink stability when drawing back.
Fig. 6 represents that cover cap 2 is positioned at contraction state.Contraction of each lid is carried out with drawing back successively, no matter is to draw back or shrink, and at first be first lid 3 motion earlier, be second lid 4, third lid 5 and Ding Gai 6 motions then successively.In the time of need shrinking as being in the state of drawing back when cover cap 1, the at first motion of first lid, the tie-beam 12 of first lid moves to the place ahead of car, and block elder generation compression spring 22 promotes the tie-beam 12 that second is covered then, repeats above-mentioned action successively, is about to cover cap 1 and shrinks; On the contrary, as need cover cap 1 is drawn back, be first lid 3 motion earlier equally, the tie-beam 12 that is first lid 3 moves to the rear of car, drives pull bar 20 and moves in the tie-beam of second lid 4, moves to the afterbody of tie-beam when the front end of pull bar 20, the tie-beam 12 that pull bar 20 just drives the second lid rearward moves, thereby second lid 4 is moved backward, repeat above-mentioned action so successively, be about to cover cap 1 and draw back.When being positioned at the position that is fully withdrawn or shrinks, pins on first lid 3, so that firm being fixed on the railway carriage of cover cap by blocking device.
See Fig. 5,6 and 9, described track 2 comprises two main skids 24 and two short slideways 25.Each main skid 24 has main skid frame 26, and two parallel main guide rails 27 are installed on main skid frame 26, chain frame wheel 28 and chain support wheel 29.Two main skid framves 24 are respectively arranged with upper plate 41, and this upper plate 30 is connected with the left and right ledge of railway carriage respectively by being hinged with lower bottom base 42 on being arranged on the left and right sides, compartment ledge.See Fig. 5 and Fig. 6, described main guide rail 27 each the lid frame upper and lower support wheel 14,16,15,17, between, when promptly cover plate moved, upper and lower support wheel 14,16,15,17 rolled on guide rail.See Fig. 8, described short slideway 25 is hinged together by middle backing plate disposed thereon 36 and the upper padding plate 35 that is arranged on the main guide rail 27.When freighting, the anterior upper and lower support wheel of each cover plate moves on this short slideway, after having adorned, moves on the main guide rail behind each lid, by two cylinders 40 two short slideways 25 is respectively rotated 90 degree to the car center, and cover cap just can fall and cover the compartment.
The outer support wheel carrier 10 of described first cover plate is driven by chain 31, and chain 31 is driven by motor 32.When motor 32 rotations, the upper and lower support wheel 14 and 15 that chain 31 drives first lid 3 rolls on guide rail 27, first lid 3 is moved, thereby spur each cover plate.When first lid 3 moved to the afterbody of car, the limit switch (not looking out) that is installed on the first lid front-axle beam 9 contacted outage with spacing block (not looking out) on being installed in main skid 24, and motor 32 is stopped operating.Equally, when first lid 2 moves to the anterior desired location of car, in two kinds of situation, during first kind of situation loading, the limit switch that is located on the first lid back rest 13 is installed is contacted outage, motor is stopped operating with spacing block on being installed in short slideway 25; Second kind of situation during unloading, is installed in the limit switch of the first lid back rest 13 and contacts outage with spacing block 21 on being installed in main skid 24, and motor is stopped operating.
Afterbody at the main skid frame has slotted hole 43, relevant position on the left and right ledge of railway carriage has pin plate 44, and when no matter freighting, unload or driving a vehicle, jam plate 44 always is inserted in the slotted hole 43, afterbody swings when preventing to be expert at car, afterbody skew when tilting during the loading or unloading compartment.
When unloading, cover cap moves to the head in compartment, when cover cap becomes 60 °-70 ° angle with level attitude, because deadweight and the influence of impacting move down cover cap, in order to increase chain, the service life of motor and cover cap and total, be provided with blocking device, this device is on the back rest 13 of first lid a locking bar 33 to be set, be respectively arranged with cylinder 36 two main skid 24 inboards, one end of this cylinder and jam plate 35 is flexibly connected by pull bar 31, see Fig. 7, the other end of jam plate 35 is provided with lock shaft 37, and jam plate is installed on the main skid by lock shaft, when work, lock shaft blocks locking bar makes cover cap labor be fixed on the head in compartment by ground, labor solidity and stability when guaranteeing unloading.
During loading, whole cover cap moves to headstock portion, and the recessing cargo space is all opened wide; During unloading, cover cap moves to headstock portion, and the recessing cargo space is covered about 75 centimetres.
Described jacking system is made up of two cylinders 38.This cylinder is fixed on the base 39 that the preceding ledge in compartment is provided with, and is connected with the below of the front support beam 37 that covers, and can make the head that covers is to rise on the center with the hinge, and afterbody descends, whole form heeling condition about 3 and spend about.During loading or unloading, will cover and be in heeling condition.During loading, two short tracks are opened with main orbit and are in same straight line, and when unloading soil and driving, short track turns back vertical with main orbit to the center, receive two main skid inboards, during driving, cover the whole horizontality that forms.
Described air-operated solenoid valve is installed between cylinder and the gas tank, is fixed on the support beam bottom, and electromagnetic valve is the 3 position-5 way electromagnetic valve, and the signal of exporting by surface-mounted integrated circuit carries out work.Cylinder piston rod is pulled out and when being retracted to assigned address, is all had limit switch to control its stroke.No matter cylinder piston rod is in running order always keeps length that gaseity is arranged with pulling out state or shrinking in the halted state cylinder.
All motions that integral body covers all are to come Control work by programmable controller input, output signal, in operator's compartment, there are two to remove a switch, the driver only need move switch, and the whole motion process that covers is finished successively by input, the output signal of programmable controller.
