Problems solved by technology

[0008] The above-mentioned problems not only exist in the forward or reverse working conditions, but also in different operating environments of construction machinery, there are corresponding differences in running resistance, and the additional loads generated by the crawler belt on the tensioner 300 will also be different, and different sizes are also required. The tension force is balanced with the additional load, and the current tension mechanism cannot provide different tension forces according to actual needs

Embodiment Construction

[0044] The content of the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0045] It should be noted that: since the pressure of hydraulic oil is directly related to the load, the pressure of the oil outlet mentioned in this document refers to the maximum pressure of the oil outlet when the hydraulic tensioning mechanism is under load.

[0046] Such as figure 2 As shown, this figure is a schematic diagram of the principle of the construction machinery crawler tensioning device provided by Embodiment 1 of the present invention. The construction machinery crawler tensioning device provided in Embodiment 1 includes a hydraulic system with a hydraulic motor 10 (only the hydraulic motor 10 is shown in the figure), a hydraulic tensioning mechanism 30 and a pressure control unit 2...

Abstract

The invention discloses an engineering machinery track tensioning device, track type engineering machinery and a method for adjusting engineering machinery track tensioning force. The disclosed engineering machinery track tensioning device comprises a hydraulic system and a hydraulic tensioning mechanism, wherein the hydraulic system provides running power for the engineering machinery, and the hydraulic tensioning mechanism is driven by hydraulic oil and provides a tensioning force for a track; the engineering machinery track tensioning device also comprises a pressure control unit; an oil inlet and an oil outlet of the pressure control unit are communicated with an auxiliary hydraulic source and the hydraulic tensioning mechanism respectively; the pressure control unit determines the running direction of the engineering machinery according to signals acquired by a main control end, and controls the pressure at the oil outlet according to the running direction of the engineering machinery; and the disclosed method also can adjust the magnitude of the tensioning force according to the running direction and the magnitude of the running resistance. The technical proposal provided bythe invention can make the tensioning mechanism provide the tensioning force with different magnitudes for the track according to the practical working state of the engineering machinery under the condition of not changing the tightness degree of the track.

Description

technical field [0001] The invention relates to a technology of crawler construction machinery, in particular to a construction machinery crawler tensioning device and a crawler construction machinery equipped with the device, and also relates to a method for adjusting the tension force of the construction machinery crawler. Background technique [0002] Because the crawler-type traveling mechanism has the advantages of large traction force, low ground pressure, and strong climbing ability, it is widely used in construction machinery; Provide a predetermined tension to make the track have the appropriate degree of tightness. [0003] At present, the tensioning mechanism of the crawler generally includes a tensioning wheel and a supporting member. The supporting member provides an appropriate supporting force for the tensioning wheel, so that the tensioning wheel keeps matching with the track; Provide proper tension to make the track have proper tightness. If the tension pr...
