Abstract
The utility model relates to a dual-drive floating-box track-type amphibian construction vehicle chassis pertaining to a technical field of construction vehicles. Two ends of the front driver are respectively provided with low-speed big-torque hydraulic motors, which are connected with revolving drums through the respective planetary reduction gears. A tension device consists of a buffered spring and an Albany grease cylinder. The buffered spring is wound at the outer wall of the Albany grease cylinder. The track shoe cavities of the spaced tracks are positioned with enforcing ribs. When operated, the low-speed, big-torque hydraulic motors change the single-driver into a dual-drivers, thus increasing the drive force by one times; the tension device is alternated into a tension device of buffered Albany grease cylinder with a spring, thus resolving the problem of rupture of the idler wheel chain and derailment of the track; the track shoe cavity is rectangular, thus resolving the problem of distortion, bend and rupture of the track shoe. The utility model is suitable for amphibian purposes, especially for operation and drive on the muddy wetland, tidal flat and the swampland.
Description
Technical field:
The utility model belongs to the construction machinery and equipment technical field, is the amphibious construction machinery and equipment of a kind of buoyancy tank crawler type chassis.
Background technology:
The amphibious construction machinery and equipment of existing buoyancy tank crawler type chassis, substantially be to adopt the actuating device of land with similar same level machinery, mainly constitute by buoyancy tank assembly, interval type crawler belt, vehicle frame, Das Vorderradfahrwerkmit Vorderradantrieb and tightening device, every side is single the driving, tightening device then is the screw rod fixed type, and the interval type crawler belt does not then have the muscle track shoe by square shape and forms.Because the amphibious construction machinery and equipment of buoyancy tank crawler type chassis not only will operation in muddy water, but also will float boat in water, so compares with machinery with the land of similar same specification, weight is bigger, crawler belt is wideer.Cause and adopt similar same specification land when travelling and climb, the propulsive effort wretched insufficiency can occur, influenced the cruising of amphibious construction machinery and equipment, smoothly by the sloping bank and the waters of coming in and going out with the amphibious construction machinery and equipment of the single actuating device of the every side of type construction machinery and equipment.Amphibious in addition chassis crawler width strengthens with type construction machinery and equipment crawler width at double than the land, causes the track shoe of at both ends supporting bending, distortion and fracture often to occur.Owing to adopt screw rod fixed type tightening device when crawler belt is subjected to impact load, can't cushion automatically, cause chain to produce fracture and derailing, also influenced the normal performance of amphibious construction machinery and equipment effect.
Summary of the invention:
The technical problems to be solved in the utility model provides and is a kind ofly keeping increasing power-handling capability under the little situation about becoming of original buoyancy tank caterpillar chassis basic version, and guarantees the buoyancy tank caterpillar chassis that crawler belt can normal operation.
The scheme of the utility model technical solution problem is at the two ends of Das Vorderradfahrwerkmit Vorderradantrieb low speed large torque HM Hydraulic Motor to be housed respectively, by planetary reduction gear connection connection rotating cylinder separately; Tightening device is made of recoil spring and butter oil cylinder, and recoil spring is around butter oil cylinder outer wall place; The track shoe cavity internal fixation of interval type crawler belt has reinforced rib.During work, low speed large torque HM Hydraulic Motor changes the list driving of original every side buoyancy tank into two synchronously the driving, propulsive effort is doubled, by reducing moving velocity, satisfy the power requirement that amphibious construction machinery and equipment travels and climbs, original fixed type screw take-up is changed into the buffering butter oil cylinder tightening device of band spring, solved the derailing problem of fracture of roller chain and crawler belt, change former track shoe cavity hollow into be with reinforced rib day font track shoe, solved distortion, bending and the breakage problem of track shoe.
The utility model is suitable for amphibious, and be specially adapted to operation in wetland, beach and the swampy terrain muddy water at soft mire and travel, reliable working performance, simple in structure.

The specific embodiment:
The utility model is made of buoyancy tank assembly 1, interval type crawler belt 2, vehicle frame 3, Das Vorderradfahrwerkmit Vorderradantrieb 4 and tightening device 5, at the two ends of Das Vorderradfahrwerkmit Vorderradantrieb 4 low speed large torque HM Hydraulic Motor 6 is housed respectively, by planetary reduction gear 7 connection connection rotating cylinders 8 separately; Tightening device 5 is made of recoil spring 9 and butter oil cylinder 10, and recoil spring 9 is around butter oil cylinder 10 outer wall places; The track shoe 11 cavity internal fixation of interval type crawler belt 2 have reinforced rib 12.
Claims (1)
1, a kind of two amphibious construction machinery and equipment of buoyancy tank crawler type chassis that drives, constitute by buoyancy tank assembly, interval type crawler belt, vehicle frame, Das Vorderradfahrwerkmit Vorderradantrieb and tightening device, it is characterized in that: low speed large torque HM Hydraulic Motor is equipped with at the two ends of Das Vorderradfahrwerkmit Vorderradantrieb respectively, by planetary reduction gear connection connection rotating cylinder separately; Tightening device is made of recoil spring and butter oil cylinder, and recoil spring is around butter oil cylinder outer wall place; The track shoe cavity internal fixation of interval type crawler belt has reinforced rib.
