Abstract
The utility model relates to a lifting mechanism for a caterpillar band of a tractor. The lifting mechanism comprises an air cylinder, a slide rail, an upper caterpillar band bracket, a fixed seat, two mounting seats and a guide pillar, wherein the slide rail is connected with the air cylinder; the upper caterpillar band bracket is supported by the slide rail; the fixed seat is fixed on an upper caterpillar band and is provided with a groove matched with the slide rail; the two mounting seats are located on two sides of the fixed seat and are mounted on the upper caterpillar band; the guide pillar is fixed on the upper caterpillar band, and racks are arranged on the outer side of the guide pillar; the two mounting seats are connected with gears meshed with the racks; a guide sleeve covers the gears, are mounted on the mounting seats and are arranged at the outer part of the guide pillar; a locking mechanism is further arranged on the guide sleeve. The lifting mechanism has the beneficial effects that by utilizing a gear-rack structure, the bearing capacity is high, the transmission accuracy is high, and the impact and the vibration of the upper caterpillar band to a lower caterpillar band because the air pressure is instable when the air cylinder is lifted can be reduced.
Description
Technical field
The utility model relates to a kind of hauling machine crawler lifting mechanism, belongs to pipe production line hauling machine technical field.
Background technology
At present the guide pin bushing guide pillar structures that adopt when domestic pipe production line hauling machine crawler lifting, high to required precision more, needs adjustment and installation repeatedly, inconvenient maintenance, wastes time and energy, so cost is relatively high.Some employing rocking arm forms, drive rocker arms roll by cylinder assembly, thereby realize the elevating movement of upper track frame, but there is no guider, completely rely on by the sliding friction of grid and realize, the uncertainty of cylinder assembly in addition, this guiding is just accurate more not.
Chinese Patent Application No. is: 02238520.7 utility model patent discloses a kind of Linear guide rail lifting device for section tractor, two supports are set below upper track frame on lathe bed, support one side has the line slideway of controlling lifting, has respectively slide block mechanism to be connected with the cylinder assembly being fixed on lathe bed base with rotating shaft mechanism on line slideway.The compensating movement of the lifting of upper track frame slide block mechanism and rotating shaft mechanism in the motion of two cylinders and lifting process, guaranteed elevating movement steadily, flexibly, reliable.But elevating movement will rely on two cylinders jointly to complete, the compensating movement of slide block mechanism and rotating shaft mechanism, the final balance that realizes upper track frame, complex structure and operation inconvenience in addition simultaneously.Therefore, this structure needs to improve.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple in structure, easy to operate, hauling machine crawler lifting mechanism that cost is lower.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
One hauling machine crawler lifting mechanism, is characterized in that, comprises cylinder; The slide rail being connected with described cylinder; The upper crawler rack being held up by described slide rail; Be fixed on crawler belt and be provided with the holder of the groove that matches with described slide rail; Be positioned at described holder both sides, be arranged on two mount pads on crawler belt; Be fixed on described upper crawler belt, outside is with the guide pillar of tooth bar; Described mount pad is connected with the gear being meshed with described tooth bar; Described guide pillar outside be provided with comprise residence state gear, be arranged on the guide pin bushing on described mount pad; On described guide pin bushing, be also provided with retaining mechanism.
Further, slide rail lower end has helicla flute, is connected by nut with cylinder.
Further, holder is circular, is arranged on the middle part of crawler belt.
Further, on the sidewall of described guide pillar, offer vertical slot, vertical slot is parallel with the axis of guide pillar, and tooth bar is embedded in vertical slot.
Further, described retaining mechanism is made up of plug, and plug is meshed with described tooth bar.
The beneficial effects of the utility model are, adopt gear & rack structure, and bearing capacity is large, transmission accuracy is higher, and can reduce because of cylinder lifting time, air pressure is unstable causes upper crawler belt to clash into and vibration lower crawler belt.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Mark in figure: 1, lifter wheel, 2, fixed gear, 3, mount pad, 4, slide rail,
5, holder, 6, lift cylinder.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation the present embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable.In accompanying drawing, describe position relationship only for exemplary illustration, can not be interpreted as the restriction to this patent.
As shown in Figure 1, when upper crawler belt initially rises, lift cylinder 6 moves, the slide rail 4 that cylinder 6 connects rises, slide rail 4 is arranged on crawler belt holder 5, and upper crawler belt rises, and is fixed on mount pad 3 on crawler belt and drives lifter wheel 1 (to be arranged on lower crawler belt) on stationary rack to rise.Decline same principle.Compared with past guide pin bushing guide pillar lifting form, lifting is steady, installs more convenient.Rack-and-pinion is because self-bearing capacity is large, transmission accuracy is higher, and can reduce because of cylinder lifting time, air pressure is unstable causes upper crawler belt to clash into and vibration lower crawler belt.
The above is only preferred embodiment of the present utility model, should be understood that, for those skilled in the art, not departing under the prerequisite of the utility model principle, can do the improvement of some applicable actual conditions to the technical scheme of utility model.Therefore, protection domain of the present utility model is not limited to this, and those of skill in the art are any to be included within the utility model protection domain based on non-material change in technical solutions of the utility model.
