Abstract
The utility model relates to a telescopic tracked chassis, which is composed of the oil cylinder, the driving wheel, weight bearing wheels, guidance wheels, supporting wheels, and tracks. The change of the width of the edge rack of tracks is implemented by the telescopic movement of two oil cylinder arranged opposite to each other of the telescopic tracked chassis, the change of the tension degree is implemented by the tensioning device, and the tensioning device is connected between the weight bearing wheel and the guidance wheel in adaptation to the working environment. The chassis is compact is the structure, and the edge rack is in the contracted state when the machine works inside the large-scale building of narrow spaces, so that the chassis is capable of easily passing through the narrow area. The edge rack is in the expanded state when the machine is driven indoor or on uneven ground, so that the steady driving of the whole machine is ensured.
Description
Technical field
The utility model relates to a kind of crawler belt, be applied to high-altitude operation platform, excavating machine, wooden fork installation, mine machinery, revolve equipment such as digging brill, for little tonnage can enter in the heavy construction and the construction machinery and equipment in narrow and small zone provides power.
Background technology
Like product width commonly used at present generally all can not be regulated, and degree of tension can be regulated, but regulating effect is bad.
The utility model content
The purpose of this utility model provides a kind of telescopic crawler body structure.
The purpose of this utility model is achieved through the following technical solutions.
A kind of flexible crawler body is made up of oil cylinder, drive wheel, caterpillar wheel, track adjusting wheel, support roller and the crawler belt of realizing Telescopic.Described flexible chassis relies on the stretching of two oil cylinders that is oppositely arranged to realize the variation of crawler belt limit frame width, and the variation by tightening device realization Zhang Jindu can adapt to different working environments, and described tightening device is connected between caterpillar wheel and the track adjusting wheel; Described chassis walking manner be by driving speed reducer motor output torque to drive wheel, rely on four-wheel one band (four-wheel one band refers to drive wheel, caterpillar wheel, track adjusting wheel, support roller and crawler belt) system to realize advancing, retreat, turning to of car load then.Described chassis structure form is small and exquisite, when machine during in heavy construction inside or work in narrow space the limit frame be in retracted mode, can easily pass through narrow and small zone.When machine travels on outdoor or unfairness ground, the limit frame is in extended state, guarantees that complete machine steadily walks.
The telescoping mechanism of described crawler body is made up of the box slideway of two oil cylinders and car load underframe, the change width of the telescopic drive whole chassis of oil cylinder.One end of oil cylinder is fixed on the frame of crawler belt limit, and the other end is fixed on the underframe of car load, and crawler belt limit frame crossbeam utilizes underframe box slideway guiding, guarantees the flexible direction and the parallelism of crawler belt limit, both sides frame.Between crossbeam and the box slideway nylon slide block is housed, the friction when sliding to reduce guarantees that crawler belt limit frame is capable of expansion and contraction.
Tightening device mainly is made up of tensioning spring, tensioning hydro-cylinder, anchor fitting and the alemite of push rod, compressive state, is installed on the frame in-to-in baffle plate of crawler belt limit by anchor fitting, and push rod and track adjusting wheel slideway match.Tightening device injects butter by alemite in tensioning hydro-cylinder, oil cylinder is upheld, and push rod promotes the track adjusting wheel slideway, thus common tensioned tracks such as the track adjusting wheel of making and tugboat drive wheel, guarantee stable the contacting of crawler belt energy in the driving process, guarantee running stability with four-wheel.Thereby can recover crawler belt is loosened by spring by the venting butter as the crawler belt tension.The adjusting of butter cylinder can move crawler belt under suitable tensioning degree, also can prolong the service life of crawler belt.
Described chassis development purpose be serve operation in heavy construction or narrow and small zone high-altitude operation platform.Under contraction state, enter building or narrow and small zone, finish the operations such as high-altitude installation and maintenance in these zones.This device is applied to the crawler tensioning of crawler body more, guarantees the driving stability of crawler body.

Fig. 1 is the front view of flexible crawler belt;
Fig. 2 is the birds-eye view of flexible crawler belt;
Fig. 3 is the constructional drawing of tightening device among Fig. 1;
Fig. 4 be among Fig. 3 A to view.
Among the figure: 1, track adjusting wheel 2, tightening device 3, caterpillar wheel 4, drive wheel 5, crawler belt 6, oil cylinder 7, crawler belt limit frame crossbeam 8, car load underframe box slideway 9, support roller 10, limit frame 21, push rod; 22, tensioning spring; 23, tensioning hydro-cylinder; 24, anchor fitting; 25, alemite
The specific embodiment
Shown in Fig. 1-2, flexible crawler body is made up of realization flexible oil cylinder 6, drive wheel 4, caterpillar wheel 3, track adjusting wheel 1, support roller 9 and crawler belt 5.Described flexible chassis relies on two oil cylinders, the 6 flexible variations that realize crawler belt limit frame width that are oppositely arranged, and the variation by tightening device 2 realization Zhang Jindu adapts to different working environments, and described tightening device 2 is connected between caterpillar wheel 3 and the track adjusting wheel 1; Described chassis walking manner be by driving speed reducer motor output torque to drive wheel, rely on four-wheel one band (four-wheel one band refers to drive wheel 4, caterpillar wheel 3, track adjusting wheel 1, support roller 9 and crawler belt 5) system to realize advancing, retreat, turning to of car load then.Described chassis structure form is small and exquisite, when machine limit frame 10 retracted modes during in heavy construction inside or work in narrow space, can easily pass through narrow and small zone.When machine travelled on outdoor or unfairness ground, the limit frame was in extended state, and the assurance complete machine is steadily walked.
The telescoping mechanism of described crawler body is made up of the box slideway 7 of two oil cylinders 6 and car load underframe, the change width of the telescopic drive whole chassis of oil cylinder.One end of oil cylinder is fixed on the frame of crawler belt limit, and the other end is fixed on the underframe of car load, and crawler belt limit frame crossbeam 7 utilizes underframe box slideway 8 guiding, guarantees the flexible direction and the parallelism of crawler belt limit, both sides frame.Between crossbeam and the box slideway nylon slide block is housed, the friction when sliding to reduce guarantees the capable of expansion and contraction of crawler belt limit frame.
As shown in Figure 3-4, tightening device mainly is made up of tensioning spring 22, tensioning hydro-cylinder 23, anchor fitting 24 and the alemite 25 of push rod 21, compressive state, be installed on the frame in-to-in baffle plate of crawler belt limit by anchor fitting 24, push rod 21 and track adjusting wheel slideway match.Tightening device injects butter by alemite 25 in tensioning hydro-cylinder 23, oil cylinder is upheld, and push rod 21 promotes the track adjusting wheel slideway, thus common tensioned tracks such as the track adjusting wheel of making and tugboat drive wheel, guarantee stable the contacting of crawler belt energy in the driving process, guarantee running stability with four-wheel.Thereby if the crawler belt tension can recover crawler belt is loosened by spring by the venting butter.The adjusting of butter cylinder can move crawler belt under suitable tensioning degree, also can prolong the service life of crawler belt.
