Abstract
The utility model discloses a caterpillar track tensioning mechanism of an excavator, and the mechanism comprises a guide wheel, a caterpillar track, a caterpillar track frame, a nut and a screw. The caterpillar track tensioning mechanism of the excavator is characterized in that the caterpillar track is arranged on the guide wheel, the screw is assembled on the screw hole of a caterpillar track frame baffle, the end of the screw is pushed to a locating hole of a support base of the guide wheel, and a gap is left between the end and the locating hole. The screw is adopted to push the guide wheel to achieve the purpose of tensioning the caterpillar track of the excavator. The caterpillar track tensioning mechanism is simple in structure, compact in arrangement, convenient in manufacture, low in cost and remarkable in effect.
Description
Technical field
The utility model relates to a kind of excavating machine track tension device.
Technical background
The track tension device of existing excavating machine; General structure is generally utilizes tensioning hydro-cylinder promotion guide wheel to move to the left, increases the width between centers distance of guide wheel and drive wheel, thereby reaches slack-free purpose; This stretching device complex structure; Parts are more, and manufacturing cost, maintenance cost are higher, and it is bigger to take up room.
Summary of the invention
The problem of the required solution of the utility model is, provides a kind of new structure to screw in track frame to screw rod, can promote guide wheel, and crawler belt is followed guide wheel and turned left together, thereby reaches the purpose of tensioned tracks, reduces arrangement space, reduces the complete machine cost.
The technical solution of the utility model is such: a kind of excavating machine track tension device; Comprise guide wheel, crawler belt, track frame, nut, screw rod; It is characterized in that crawler belt is assemblied on the guide wheel; Screw fits on the track frame, screws in track frame pushing tow guide wheel through screw rod, and screw rod passes through with nut locking on track frame.
The utility model has the advantages that and adopt a screw rod to replace tensioning hydro-cylinder, promote guide wheel and move to the left, reach slack-free effect.Simple in structure, with low cost, effect obviously, change convenient.
Description of drawings
It is such that the structure of the utility model constitutes:
Fig. 1 is that the utility model structural entity is installed the assembling scheme drawing.
Fig. 2 is the scheme drawing of the utility model screw rod.
Fig. 3 is the scheme drawing of the utility model nut.
Among Fig. 1～Fig. 3, guide wheel (1), crawler belt (2), track frame (3), nut (4), screw rod (5).
The specific embodiment
The most preferred embodiment of the utility model is such; With reference to accompanying drawing 1～Fig. 3; Referring to accompanying drawing 1, crawler belt (2) is assemblied on the guide wheel (1), and screw rod (5) is assemblied on the screw on track frame (3) dividing plate; The knock hole on guide wheel (1) bearing is pushed up in screw rod (5) termination, is designed with suitable gap between termination and knock hole.Referring to Fig. 1, screw in track frame (3) to screw rod (5), can promote guide wheel (1) and be moved to the left, crawler belt (2) is followed guide wheel (1) and is moved to the left together, thereby reaches tensioned tracks (2) purpose.After crawler belt (2) tensioning, be locked at screw rod (5) on the track frame (3), prevent that crawler belt (2) from getting loose through nut (4).Adopt a screw rod to replace tensioning hydro-cylinder, promote guide wheel and move to the left, reach tension effects.
Claims (2)
1. excavating machine track tension device; Comprise guide wheel, crawler belt, track frame, nut, screw rod; It is characterized in that crawler belt (2) is assemblied on the guide wheel (1); Screw rod (5) is assemblied on the track frame (3), screws in track frame (3) pushing tow guide wheel (1) through screw rod (5), and screw rod (5) is through being locked on the track frame (3) with nut (4).
2. according to the described a kind of excavating machine track tension device of claim 1, it is characterized in that screw rod (5) is assemblied on the screw of track frame (3).
