Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
Referring to figs. 1 through Fig. 3, shown in it is chassis of dredging machine, and this chassis is that switchable type wheel carries out dual-purpose chassis, can carry out rubber-tyred walking or crawler-type traveling according to real-time road.This chassis comprises vehicle frame 50, and be arranged on left crawler attachment and the right-hand track chiain device of these vehicle frame both sides in parallel to each other, these two crawler attachments can carry out wheeled and crawler-mounted switching, it comprises the drive wheel 1 and tension wheel 6 that are positioned at vehicle frame two ends, multiple bearing wheed between drive wheel 1 and tension wheel 6 and multiple holder sprocket wheel, multiple jacking system, the detachable track 7 being supported by above-mentioned multiple wheel body and driven, and shock absorber 14 interconnective with tension wheel 6, wherein, jacking system can control connected bearing wheed and holder sprocket wheel carries out rising or declining, shock absorber 14 can control tension wheel 6 parallel motion.
Particularly, drive wheel 1 and tension wheel 6 lay respectively at the position, middle and upper part at vehicle frame 50 two ends, and wherein the position of drive wheel 1 is fixed and had the effect driving crawler belt, and tension wheel 6 is arranged on vehicle frame 50 movably, and it does not possess driving effect.
Multiple bearing wheed is arranged on the middle and lower part of vehicle frame 50, for supporting excavating machine and driving crawler belt 7, the plurality of bearing wheed is the first bearing wheed 2, second bearing wheed 3, the 3rd bearing wheed 4 and the 4th bearing wheed 5 that are sequentially arranged between drive wheel 1 and tension wheel 6, the diameter of these four bearing wheeds is larger, cover tire is solid rubber, and the first bearing wheed 2 and the 4th bearing wheed 5 are fixedly installed on vehicle frame 50, the second bearing wheed 3 and the 3rd bearing wheed 4 are liftably arranged on vehicle frame 50.First bearing wheed 2 and the 4th bearing wheed 5 are all built-in with motor.The quantity of bearing wheed suitably can increase along with the increase of chassis length.
Multiple holder sprocket wheels are arranged on the middle and upper part of vehicle frame 50, for supporting crawler belt, the plurality of holder sprocket wheel is that the first holder sprocket wheel 9, second holds in the palm sprocket wheel 11 and the 3rd holder sprocket wheel 12, wherein, first holder sprocket wheel 9 is liftably arranged on vehicle frame 50, and the second holder sprocket wheel 11 and the 3rd holder sprocket wheel 12 are fixedly installed on vehicle frame 50;
Multiple jacking system comprise to hold in the palm with first interconnective first jacking system 8 of sprocket wheel 9, with interconnective second jacking system 10 of the second bearing wheed 3 and three jacking system 11 interconnective with the 3rd bearing wheed 4, these three lifting device structures are similar, and are mainly used in controlling connected wheel body generation rising and descending motion.Particularly, jacking system pipe link 30, tooth bar 31, gear 32, handle 33 and pin rod 34, wherein, the lower semisection of pipe link 30 is positioned at vehicle frame 50, upper semisection exposes, and the lower end of pipe link 30 is provided with several gear cotter ways 40, and vehicle frame 50 is provided with pin-and-hole 41, pin rod 34 can insert in pin-and-hole 41 and gear cotter way 40, carries out spacing to pipe link 30; Tooth bar 31 is fixedly mounted on the upper end of pipe link 30; Gear 32 and tooth bar 31 engage each other; Handle 33 and gear 32 are mutually permanently connected.Cw pulling handle 33 can driven gear 32 clickwise, because gear 32 engages with tooth bar 31, when pin rod 34 and gear cotter way 40 depart from be connected time, tooth bar 31 and pipe link 30 upward movement, pipe link 30 drives wheel body to rise again; In like manner, during conter clockwise pulling handle 33, gear 32 left-hand revolution, when pin rod 34 and gear cotter way 40 depart from be connected time, tooth bar 31 and pipe link 30 move downward, pipe link 30 drives wheel body to decline again, therefore regulates jacking system can control rising and the decline of the first holder sprocket wheel 9, second bearing wheed 3 and the 3rd bearing wheed 4.
When excavating machine needs to be converted to wheeled traveling by crawler type, need first crawler belt 7 to be dismantled, for convenient disassembly, first the second bearing wheed 3 and the 3rd bearing wheed 4 is regulated to rise 5 ~ 10cm respectively by the second jacking system 10 and the 3rd jacking system 12, the first holder sprocket wheel 9 is regulated to decline 5 ~ 10cm by the first jacking system 9 again, regulate tension wheel 6 to bounce back by shock absorber 14 again, above-mentioned adjustment makes the crawler belt 7 of tensioning loosen; Usage mining arm (not shown) by the support of the front portion on chassis overhead, being opened by the connecting pin of middle, liftoff for crawler belt 7 side makes crawler belt 7 disconnect, putting of disconnecting ground part crawler belt 7 is turned over and put into crawler belt putting groove 15, then bayonet lock 16 is used to be fixed, by digging arm (not shown), rear portion, chassis is supportted overhead again, be placed in groove 15 by crawler belt 7 remainder turning over and putting into crawler belt in the same way, then use bayonet lock 17 to be fixed; In the same fashion opposite side crawler belt is dismantled; Startup is built-in with motor first bearing wheed 2 and the 4th bearing wheed 5 can carry out road running, turns to differential principle.
In sum, of the present invention rational in infrastructure, can switch walking manner in real time according to work requirements and surface conditions, make excavating machine all be adapted to road and road running, maneuvering performance is strong, and operating range is wide, and takes turns, carries out easy switching, fast.
