Description
Technical field
The utility model relates in the depth of water and carries out the vehicle equipment that travels that engineer operation is used less than transition zone, marsh, the lake of 1.5m, the chain stretching device on the amphibious chassis of travelling of particularly a kind of floating box type.
Background technique
The amphibious vehicle equipment chassis of travelling mainly contains following four kinds of patterns: wheel undercarriage, caterpillar chassis, various ship type equipment and floating box type chassis.Wheel undercarriage has two kinds of rubber tyre and steel wheels, and using scope is mainly sandy beach type beach and contains the swampy terrain of a small amount of muddy water.Caterpillar chassis is divided into two kinds on rubber belt track and steel crawler belt, and rubber caterpillar type uses restricted on the meadow, be subject to stormy waves, water currents; Steel track-laying vehicle such as cat, military creeper truck tank, armored vehicle etc. have certain marsh passing capacity.Various ship type equipment mainly contain air ship, Hovercraft etc.The air ship adopts high-powered engine, and propeller cavitation promotes, and has the area of water or the grass effect of travelling preferable on the surface, and shortcoming is to be held by mud easily, and direction control is inaccurate.There are two sealing buoyancy tanks on the floating box type chassis, realizes walking by both sides chain transferring power, and grounding pressure is low, and floatability is good, on various mud, the mixed face of land of water and meadow passing capacity is preferably arranged all.
Consult Fig. 1 a.At present, at an end of buoyancy tank 9 driving shaft is arranged, the two ends of driving shaft are fixed with drive sprocket.The other end at buoyancy tank has tensioning platform 10, is fixed with floating box type chassis chain stretching device on the tensioning platform 10.The chassis chain stretching device comprises bearing slider 1, sprocket wheel 2, engaging lug seat 3, tensioning fixed base 4, tensioning nut 5, tensioning screw 6 and driven shaft 8.The two ends of driven shaft 8 a stretcher arranged respectively.Stretcher is in the outside of sprocket wheel 2.By the tensioning nut 5 on the difference precession tensioning fixed base 4, the bearing slider 1 that promotes driven shaft 8 left and right sides moves respectively, thereby the sprocket wheel 2 on driven shaft 8 two ends is moved, and realizes chain 7 tensionings respectively.The deficiency of this structure is: in chain 7 tensioning processes, need the tensioning nut 5 of precession driven shaft 8 left and right sides respectively, tensioning nut 5 promotes tensioning screw 6, and the distance between tensioning fixed base 4 and the driven shaft 8 is changed.The operation of precession tensioning nut 5 so respectively, not vertical if precession amount difference might cause driven shaft 8 deflections with the buoyancy tank center line, cause forming surface friction drag between sprocket wheel 2 and the chain 7, cause sprocket wheel 2 eccentric wears, chain 7 breaks away from problems such as sprocket wheel 2 easily.Exist the both sides chain 7 can not synchronous tension, cause degradation deficiency under the vehicle equipment driveability.
The model utility content
The purpose of this utility model is: provide a kind of floating box type the amphibious chassis chain stretching device that travels, make floating box type vehicle equipment both sides chain synchronous tension, improve the floating box type vehicle equipment in the marsh of complexity, the travelling of area, lake, passing capacity.
The technical solution adopted in the utility model is: the amphibious chassis chain stretching device that travels of floating box type, mainly form by bearing slider, sprocket wheel, engaging lug seat, tensioning fixed base, tensioning nut, tensioning screw and driven shaft, both sides at the tensioning platform have bearing slider respectively, on two bearing sliders, driven shaft is arranged, be fixed with two sprocket wheels on the driven shaft.It is characterized in that: be fixed with the tensioning push rod on driven shaft, the fixed position of tensioning push rod is between two sprocket wheels.On the tensioning push rod, be fixed with the engaging lug seat, be connected with tensioning screw on the engaging lug seat.Be fixed with the tensioning fixed base on the tensioning platform.Tensioning screw passes the tensioning fixed base.Tensioning nut 5 is arranged on the tensioning screw.The rotation tensioning nut can promote tensioning screw and tensioning push rod, and makes the parallel mobile tension chain of driven shaft.Can not produce the driven shaft skewness.
Described tensioning push rod by about two short push rods form, an end and the engaging lug seat of two short push rods are fixed, the angle between two short push rods is the obtuse angle.The other end of two short push rods is fixing with the driven shaft welding respectively.
The center line of the center line of described tensioning fixed base and engaging lug seat is on same straight line, and the distance between the vertical driven shaft of this straight line and this straight line to two sprocket wheel equates.
For chain is raise, on-stream the generation with the last plane of buoyancy tank of chain rubbed.The last plane of described tensioning platform is the inclined-plane, and the angle of tensioning platform inclination is between 10～30 degree.Be fixed on bearing slider on the tensioning platform of inclination like this behind tension chain, the segment distance that can raise supports certain altitude with whole chain.Chain can be not on-stream produce friction with the last plane of buoyancy tank.In addition, after chain supports certain altitude, can utilize the own wt tensioning bottom chain of top chain.
The beneficial effects of the utility model: the amphibious chassis chain stretching device that travels of the utility model floating box type, can realize floating box type vehicle equipment both sides chain synchronous tension, can not produce the driven shaft skewness, can utilize the own wt tension chain of top chain.Improve the floating box type vehicle equipment in the marsh of complexity, the travelling of area, lake, passing capacity.
