Description
Technical field:
The utility model relates to a kind of crawler attachment of amphibious excavating machine.
Background technology:
In recent years, the irrigation areas diversion works of China, city diversion and water supply project, Coastal beach improvement, sea reclamation works and alkaline land improvement, excavation in desilting and dredging, desilting etc., the demand of amphibian digging machine is got more and more, require also more and more higher, thus also promote the R&D work of a lot of researcher to amphibious excavating machine.
Current domestic and international widely used amphibious excavating machine is buoyancy box crawler excavator, and the chassis traveling gear of this excavating machine adopts is all the mode of the interval type crawler belt movement on buoyancy tank guide rail formed without sealing, unlubricated roller type chain and track shoe, climbing and the ability of going ashore of excavating machine are low, in water, moving velocity is low, and the buoyancy tank of the main car on the lower of this excavating machine provides buoyancy, easily occur because buoyancy deficiency causes the problem that excavating machine travels in water, job safety performance is low.
Utility model content:
The utility model is in order to make up the deficiencies in the prior art, provide a kind of crawler attachment of amphibious excavating machine, its reasonable in design, the gait of march of amphibious excavating machine in water is increased greatly, climb and go ashore ability more by force, meanwhile, larger buoyancy can be provided, make that amphibious excavating machine travels in water, operation is safer, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of crawler attachment of amphibious excavating machine, comprise main buoyancy tank, sprocket wheel and front wheel spindle and the hind axle of being with rear sprocket wheel before being located at the band of main buoyancy tank front-end and back-end, at front sprocket wheel, chain is arranged with outside main buoyancy tank and rear sprocket wheel, one motor be built in main buoyancy tank is connected with front wheel spindle by transmission device, be connected respectively a carrier bar outside each chain link of chain, each carrier bar is fixed with an auxiliary float respectively by bolt, a boss wide with auxiliary float is respectively equipped with at the Width of the lower end edge auxiliary float of the drying side of each auxiliary float, described auxiliary float comprises inner support steelframe, a vulcanised rubber layer is coated with in the outside of inner support steelframe, the cavity inside of encircling a city at inner support steelframe and vulcanised rubber layer is filled with floating material, an outer support steelframe is arranged with in one end that vulcanised rubber layer is relative with carrier bar, several bolts be located in inner support steelframe pass inner support steelframe, vulcanised rubber layer, outer support steelframe is connected with carrier bar.
The surface of the drying side of described auxiliary float is obliquely installed outward by near body one end, and the thickness of auxiliary float near body one end is greater than the thickness of outer end; Described boss surface is obliquely installed to two ends by centre, and in the middle of described boss surface, evagination is higher than two ends.
Described floating material is polyurethane.
The utility model adopts such scheme, reasonable in design, the boss that in the utility model, the drying side of auxiliary float is arranged makes the ability of the drying of auxiliary float be far longer than the drying ability of track shoe, the gait of march of amphibious excavating machine in water is increased greatly, simultaneously, except main buoyancy tank provides buoyancy, auxiliary float can provide a large amount of buoyancy, make that amphibious excavating machine travels in water, operation is safer, in addition, the ground ability of taking off of auxiliary float is strong, makes excavating machine be easy to climbing and go ashore.

Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation of auxiliary float.
Fig. 4 is the plan structure schematic diagram of the auxiliary float removing outer support frame in Fig. 3.
In figure, 1, main buoyancy tank, 2, front sprocket wheel, 3, rear sprocket wheel, 4, chain, 5, carrier bar, 6, auxiliary float, 7, inner support steelframe, 8, vulcanised rubber layer, 9, polyurethane, 10, outer support steelframe, 11, boss.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-4, a kind of crawler attachment of amphibious excavating machine, comprise main buoyancy tank 1, sprocket wheel 2 and front wheel spindle and the hind axle of being with rear sprocket wheel 3 before being located at the band of main buoyancy tank 1 front-end and back-end, at front sprocket wheel 2, chain 4 is arranged with outside main buoyancy tank 1 and rear sprocket wheel 3, one motor be built in main buoyancy tank 1 is connected with front wheel spindle by transmission device, be connected respectively a carrier bar 5 outside each chain link of chain 4, each carrier bar 5 is fixed with an auxiliary float 6 respectively by bolt, a boss 11 wide with auxiliary float 6 is respectively equipped with at the Width of the lower end edge auxiliary float 6 of the drying side of each auxiliary float 6, described auxiliary float 6 comprises inner support steelframe 7, a vulcanised rubber layer 8 is coated with in the outside of inner support steelframe 7, the cavity inside of encircling a city at inner support steelframe 7 and vulcanised rubber layer 8 is filled with floating material, an outer support steelframe 10 is arranged with in one end that vulcanised rubber layer 8 is relative with carrier bar 5, several bolts be located in inner support steelframe 7 pass inner support steelframe 7, vulcanised rubber layer 8, outer support steelframe 10 is connected with carrier bar 5.
The surface of the drying side of described auxiliary float 6 is obliquely installed outward by near body one end, and the thickness of auxiliary float 6 near body one end is greater than the thickness of outer end; Described boss 11 surface is obliquely installed to two ends by centre, and in the middle of described boss 11 surface, evagination is higher than two ends.
Described floating material is polyurethane 9.
Adopt the amphibious excavating machine of crawler attachment of the present utility model when land walking, auxiliary float 6 kiss the earth, auxiliary float 6 outside is coated with wear-resisting vulcanised rubber layer 8, inner hollow is filled with polyurethane 9, in the process of walking, the effect that buffering is shockproof can be played, just as tire.At muddy and marsh district, auxiliary float 6 is large with contact area of ground, and grounding pressure is little, more easily walking above.In water, the boss 11 arranged due to the drying side of auxiliary float 6 makes the ability of auxiliary float 6 drying be far longer than the ability of track shoe drying, the gait of march of amphibious excavating machine in water is increased greatly, simultaneously, except main buoyancy tank 1 provides buoyancy, buoyancy aid can provide a large amount of buoyancy, makes amphibious excavating machine safer in water.When auxiliary float 6 rise bottom-up along with the rotation of chain 4 time, the surface of water through being obliquely installed of auxiliary float 6 drying side flows to away from body outer end, water on boss 11 tilts to two ends through centre and middle evagination flows out higher than the surface at two ends, water on auxiliary float 6 can well be come down in torrents like this, avoid hoarding water, reduce resistance to motion.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
