Abstract
The utility model relates to a caterpillar track pressure intensity changing device, which mainly solves the problem that the caterpillar track shapes of the existing caterpillar machines (such as tanks, caterpillar excavators and caterpillar bulldozers, etc.) can not change with differences of functions or highway conditions. Hydraulic pumps are respectively arranged at the front and the back on panels at both sides of the lower part of the caterpillar machine and are connected with the panels, the end of a hydraulic rod of the hydraulic pump is simultaneously connected with two distance rods, wherein one distance rod is connected with the panel, the other distance rod is connected with a connecting rod between a climbing wheel and a load wheel, and connecting positions are all movably connected. The utility model can change the shape of caterpillar tracks and can change contact areas and pressure of the caterpillar tracks with the ground, which is convenient to adapt to different functions and highway conditions.
Description
The utility model relates to a kind of mechanism on the caterpillar machinery, particularly a kind of crawler belt pressure modifier.
At present, caterpillar machinery (as tank, traxcavator, crawler doer etc.) exists some problems to need us to think deeply in design and use and solves.For example: under the crawler belt shaped design Cheng Shangchang of tank in short-term, its cross country power just can strengthen, but crawler belt and ground-surface area of contact will reduce, tank is increased ground-surface pressure, if tank runs with regard in emboging easily, if tank runs on cement pavement with regard to the easy damaged road surface in the mire area.If the crawler belt shaped design is become upward short long down, though can overcome above-mentioned drawback, the cross country power of tank will descend.In addition, when tank was climbed, long short down if crawler belt is shaped as, crawler belt and domatic area of contact were less so, and this reduces the adhesive ability of crawler belt, and the hill climbing ability of tank just descends.It seems, can just arbitrarily change and to address the above problem if the crawler belt area is a pressure.
Thereby it is the device that crawler belt and contact area of ground can change pressure between crawler belt and the ground that the purpose of this utility model is to provide a kind of crawler belt shape that changes, and makes its caterpillar machinery can adapt to different purposes and road conditions.
The purpose of this utility model is achieved in that on the panel 15 of both sides, caterpillar machinery bottom its front and back respectively are provided with Hydraulic Pump 9 and join with panel 15; The end of the hydraulic stem 13 of Hydraulic Pump 9 joins with propelling rod 16 and 17 simultaneously; The other end of propelling rod 16 and panel 15 join, and the pipe link 3 between the other end of propelling rod 17 and climbing wheel 1 and the loadwheel 2 joins; More than each point of connection be flexible connection.
The flexible connection of above-mentioned said each point of connection is by bolt each attaching parts to be constituted detouchable " turning joint " structure.
Advantage of the present utility model is simple in structure, and is easy to operate, can arbitrarily change crawler belt and ground-surface area of contact as required, and its pressure is changed, and can make caterpillar machinery adapt to different occasion and road conditions.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is that the utility model becomes last long following structural representation in short-term with crawler belt.
Fig. 2 be the utility model with crawler belt become long down in short-term structural representation.
More than structure shown in the drawings be embodiment of the present utility model.Structure shown in the figure is the structure diagram (some wheel has omitted) of the crawler belt part of tank bottom.Among the figure, 1 is the climbing wheel; 2 loadwheels for supporting tank weight; 3 is fifth wheel 1 and the pipe link of taking turns 2 wheel shafts, and wheel 1 can be around the rotation of the axle center of wheel 2 with pipe link; 4,5,6, be " turning joint " between each attaching parts, generally adopt bolt to constitute detouchable and flexibly connect; 7 for holding the auxiliary wheel of top crawler belt; 8 for being located at the driving wheel of hull middle part, driving tank; 9 for being located at Hydraulic Pump on the body panels, and it is the propulsion source of this device; 10 for the Hydraulic Pump tail end being located at " turning joint " on the tank downside two panels, removably connects by formations such as bolts; 11,12 for sharing the loadwheel of tank weight; 13 is hydraulic stem, and an end is located in the Hydraulic Pump, and the other end and turning joint 6 are joined; 14 is the crawler belt of tank; 15 is the panel of both sides, tank bottom; 16 is upper thrust rod; 17 is lower thrust rod, and these two propelling rods and hydraulic stem 13 flexibly connect, can be effectively with the power guid pipe link of Hydraulic Pump, and it is more laborsaving that hydraulic pump works is got up.Principle of work of the present utility model is: when tank travels in mire or just needs to increase area of contact on the road time, at this moment only need Hydraulic Pump is pressurizeed, hydraulic stem 13 stretches out and propelling rod 16 and propelling rod 17 will be released, the angle of propelling rod 16 and propelling rod 1 is increased, distance between turning joint 4 and the turning joint 5 is increased, wheel 1 is depressed, made crawler belt 14 alterations of form.Crawler belt will become this shape of Fig. 2 so.Its area of contact has increased as can be seen, and at this moment tank will reduce ground-surface pressure, during tank just is not easy to embog or damage ground.If climb very steep very longly when sloping, at first tank is become cross-country status, parallel when domatic when the tank track bottom surface, again the crawler belt of tank is become the shape of Fig. 2, just can increase adhesive ability, so be easy to make the grade.When needs strengthen cross country power, only need Hydraulic Pump is reduced pressure, at this moment hydraulic stem will retract propelling rod 16 and propelling rod 17, the angle of propelling rod 16 and propelling rod 17 is reduced, distance between turning joint 4 and the turning joint 5 is reduced, wheel 1 is risen, become this shape of Fig. 1.This device all is set before and after the tank both sides.Four switches can be regulated four devices respectively according to different road conditions.
Claims (2)
