Abstract
The utility model relates to a track supporting and connecting structure of a tracked dragger. The track supporting and connecting structure comprises clamping blocks, chains, connection shafts, idler wheels and supporting guide rails, wherein the idler wheels are arranged on the connection shafts connected with the clamping blocks. The track supporting and connecting structure is characterized in that each external chain board of each chain is provided with one clamping block, the inner side of each clamping block is an arc surface, the arc surface of the inner side of each clamping block is provided with net patterns, the idler wheels on the clamping blocks are connected to the connection shafts through needle bearings, and the idler wheels are in rolling friction with the supporting guide rails. The track supporting and connecting structure is reasonable in design, simple in structure, easy to manufacture, convenient to install and maintain, long in service life and high in transmission efficiency.
Description
Technical field
The utility model relates to the drive technology field of caterpillar tractor, specifically a kind of crawler belt of caterpillar tractor supporting syndeton.
Background technology
At present, the crawler belt support pattern of caterpillar tractor be mainly by chain stays in guide rail top, clamp is connected on driving chain.The chucking power of tractor is delivered on the roller of chain by guide rail, then passes to clamp by the attached plate on chain.There is certain defect in this structure, tractor crawler belt be can not bearing high strength radial load.Owing to there is friction between chain roller and guide rail, the pressure between roller and guide rail increases with the increasing of chucking power.The rolling friction increasing between certain value rear chain roller and guide rail when pressure becomes sliding friction, and the large and sliding friction of sliding-frictional resistance easily produces huge heat, has accelerated the wearing and tearing of guide rail and driving chain, and application life is short.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned technology, provides a kind of reasonable in design, simple in structure, does not contact the crawler belt supporting syndeton of the caterpillar tractor of long service life between guide rail and chain.
The technical scheme that the utility model adopts is: a kind of crawler belt supporting syndeton of caterpillar tractor, comprise clamp, chain, connecting axle, roller, support rails, roller is on connecting axle, connecting axle is connected with clamp, it is characterized in that, on every joint outer plate of chain, clamp is installed, the inner side of clamp is arc surface, on the arc surface of clamp inner side, be provided with reticulate pattern, roller on clamp is needle bearing on connecting axle, and roller contacts as rolling friction with support rails.
The utility model is reasonable in design, simple in structure, easily manufacture, and installation, easy to maintenance, long service life, transmission efficiency is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 top view.
Fig. 3 is use state diagram of the present utility model.
Mark in figure: 1, clamp, 2, chain, 3, connecting axle, 4, roller, 5, support rails, 6 pipelines.
Detailed description of the invention
Shown in Fig. 1,2, a kind of crawler belt supporting syndeton of caterpillar tractor, comprise clamp 1, chain 2, connecting axle 3, roller 4, support rails 5, roller 4 is on connecting axle 3, and connecting axle 3 is connected with clamp 1, on every joint outer plate of chain 2, clamp 1 is installed, the inner side of clamp 1 is arc surface, on the arc surface of clamp 1 inner side, be provided with reticulate pattern, the roller 4 on clamp 1 is needle bearing on connecting axle 3, and roller 4 contacts as rolling friction with support rails 5.
It shown in Fig. 3, is the use state diagram that caterpillar tractor of the present utility model is applied to oil-field flooding well lines and rises up into the use of going into the well.Tractor in use, has reticulate pattern clamping pipeline 6 on the arc surface of clamp 1 inner side on the every joint outer plate on chain, have the roller 4 that is needle bearing on the connecting axle 3 on clamp 1, and roller 4 contacts as rolling friction with support rails 5.Radial load can be born because roller adopts needle bearing, and the lateral force of some strength can be born.On each outer plate due to chain, all add clamp, strengthen the contact area with clamping pipeline, make the whole crawler belt uniform stressed of tractor, on clamp arc surface with reticulate pattern, strengthen the frictional force with clamping tube surfaces, because chain does not contact with support rails, little for rolling frictional resistance between clamp and support rails directly contact, greatly improve transmission efficiency; Clamping force is directly passed to clamp by support rails, for pipeline provides tractive force.
