Abstract

A tensioning mechanism for moving caterpillar bands comprises a tensioning oil cylinder, a retaining plate, a guiding shaft, a tension spring, a connection board and a piston plate, wherein the guiding shaft and the tensioning oil cylinder are arranged on the two end surfaces of the connection board, one end of the tensioning oil cylinder is connected with the retaining plate, the piston plate is arranged on the guide shaft, the tension spring is arranged between the piston plate and the connection board. The tensioning mechanism can automatically adjust the tightness of the caterpillar band, and lightens the work load of workers. The tensioning mechanism has elasticity and excellent adjusting effect, can buffer the tension force of rough roads for the caterpillar band, prolongs the service life of the caterpillar band, and has simple structure, excellent use effect and low production cost.

Description

A kind of stretching device that is used for traveling crawler

Technical field

The utility model relates to a kind of crawler type walking mechanism, specifically a kind of stretching device of traveling crawler.

Technical background

Crawler type walking mechanism is usually used in development machine, vehicle such as bulldozer and track type tractor, crawler type walking mechanism is usually worked in complex environment, environment is abominable, workload is heavy, crawler belt is extended easily, in order to adapt to the elongation of crawler belt, keep the propulsive effort of crawler belt, need regulate the tensioning degree of crawler belt, manual regulation not only efficient is low, and strengthened workman's work load, usually the stretching device that is provided with is the rigidity tensioning, though reduced workman's work load, regulated quantity is difficult for grasping, the little out of reach effect of regulated quantity, regulate excessive too tight that crawler belt stretches tight that make easily, when running into uneven road surface, the pulling force that crawler belt bears is not stopped paying out changing yet, crawler belt too tightly ruptures easily, and existing stretching device can't meet requirements.

Summary of the invention

The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and providing a kind of can regulate the crawler belt degree of tightness automatically, and can cushion the stretching device that is used for traveling crawler of crawler belt tension variations.

The utility model is that the technical scheme that deficiency adopted that solves the problems of the technologies described above is:, a kind of stretching device that is used for traveling crawler, constitute by tensioning hydro-cylinder, adapter plate, the axis of guide, tensioning spring, connecting panel and piston plate, the axis of guide and tensioning hydro-cylinder are arranged on two end faces of connecting panel, tensioning hydro-cylinder one end is connected with adapter plate, the axis of guide is provided with piston plate, is provided with tensioning spring between piston plate and the connecting panel.

The utility model, described piston plate and axis of guide sliding block joint.

The utility model, described piston plate one side is provided with jam nut.

The utility model, stretching device is contained in the track frame of traveling gear, and adapter plate is contained on the middle fixed mount of track frame, and piston plate withstands on the track adjusting wheel of crawler belt, adjusting the flexible of oil cylinder can track adjusting wheel slide in track frame, thereby adjusts the tensioning degree of crawler belt.

The beneficial effects of the utility model are:

1, can automatically regulating crawler belt elasticity, alleviated workman's work load.

2, stretching device has elasticity, adjusts effective.

3, can cushion the pulling force that cause of uneven road surface, prolong crawler belt service life crawler belt.

4, simple in structure, result of use is good, and productive costs is low.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Mark among the figure: 1, tensioning hydro-cylinder, 2, the axis of guide, 3, tensioning spring, 4, connecting panel, 5, adapter plate, 6, piston plate, 7, jam nut.

The specific embodiment

As shown in the figure, a kind of stretching device that is used for traveling crawler, constitute by tensioning hydro-cylinder 1, adapter plate 5, the axis of guide 2, tensioning spring 3, connecting panel 4 and piston plate 6, the axis of guide 2 and tensioning hydro-cylinder 1 are arranged on two end faces of connecting panel 4, tensioning hydro-cylinder 1 one ends are connected with adapter plate 5, the axis of guide 2 is provided with the piston plate 6 that can slide thereon, is provided with the tensioning spring 3 that is sleeved on the axis of guide 2 between piston plate 6 one sides and the connecting panel 4, and opposite side is provided with jam nut 7.

The utility model, adapter plate 5 are fixed on the interior fixed mount of track frame, and piston plate 6 is connected with the track adjusting wheel of crawler belt, to sinciput, tensioning spring 3 is compressed tensioning hydro-cylinder 1 with connecting panel 4, simultaneously with piston plate 6 to sinciput, drive track adjusting wheel to front slide, make crawler tensioning.When running into uneven road surface, tensioning spring 3 can play buffer action again, alleviates the load of crawler belt, prolongs the service life of crawler belt.
