Abstract

The invention provides a crawler belt tensioning device and crawler belt type engineering machinery, and relates to the technical field of engineering machinery. The crawler belt tensioning device comprises a cylinder body, a pull rod, a support, an ejector rod, a spring and an elastic buffering piece. One end of the cylinder body is connected to the pull rod; the support is slidably connected tothe pull rod and used for being connected with a guide wheel of a tensioning crawler; the end, away from the pull rod, of the cylinder body is connected to the ejector rod; and the ejector rod can extend out relative to the cylinder body to abut against a chassis limiting plate of the crawler-type engineering machine. The cylinder body is sleeved with the spring, one end of the spring is connectedto the cylinder body, the other end of the spring is connected to the support, the buffering piece is connected to the spring, and at least one part of the buffering piece is located between two adjacent coils of the spring. The crawler-type engineering machinery comprises the crawler belt tensioning device. The crawler belt tensioning device can reduce damage to the spring and reduce the influence on the reliability of the device and crawler belt type engineering machinery.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a crawler tensioning device and a crawler construction machinery. Background technique [0002] Construction machinery such as crawler excavators use crawlers to walk, which has the advantages of large traction, low grounding ratio, and strong climbing ability. The track tensioning device can adjust the tension to improve the track performance. In the prior art, the track tensioning device mostly adopts a spring connected to the guide wheel bracket of the track. The spring can provide pre-tensioning force, and can absorb impact and provide buffer, which can reduce the damage of large impact load to the track, etc., and Improve driving experience. However, when the structure of the existing track tensioning device encounters a large impact, it is easy to damage the spring, affect the life of the spring, and then affect the reliability of the device.
