Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can be by this descriptionDisclosed content is understood other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 4. Notice, appended graphic the illustrated structure of this description, ratio, size etc., all only in order toThe content that coordinates description to disclose, understands and reads for person skilled in the art scholar, not can in order to limit the utility modelThe qualifications of implementing, thus the technical essential meaning of tool not, the tune of the modification of any structure, the change of proportionate relationship or sizeWhole, not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the utility model and take offThe technology contents showing obtains in the scope that can contain. Meanwhile, in this description, quote as " on ", D score, " left side "," right side ", " centre " and " one's " etc. term, also only for ease of understanding of narrating, but not can in order to limit the utility modelThe scope of implementing, the change of its relativeness or adjustment, changing under technology contents without essence, can when being also considered as the utility modelThe category of implementing.
As shown in Figures 1 to 4, pedrail mechanism of the present utility model, comprises main shaft 1, driving wheel 2 and crawler belt 3, crawler belt 3 byElastomeric material manufacture forms, and cost is low, wear-resisting, long service life, and one end of main shaft 1 is through driving wheel 2 and make driving wheel 2Rotate. The holder combination 4 that is provided with bar-shaped trough 41 is installed on main shaft 1, and holder combination 4 is cuboid platy structure, support groupClose on 4 one end away from main shaft 1 regulating wheel 9 is installed. Drive sprocket 7 is installed on one end of main shaft 1, and drive sprocket 7 is logicalCross chain and exterior power equipment connection, drive sprocket 7 rotates and drives main shaft 1 to rotate, and main shaft 1 drives driving wheel 2 to rotate.The two ends of crawler belt 3 are enclosed within respectively on regulating wheel 9 and driving wheel 2, and regulating wheel 9 and driving wheel 2 support crawler belt 3, driving wheel 2Drive crawler belt 3 to move, crawler belt 3 is connected and moves with regulating wheel 9 and driving wheel 2. Regulating wheel 9 is along holder combinationBar-shaped trough 41 on 4 moves the distance of adjusting with driving wheel 2, thereby adjusts the tensioning degree of crawler belt 3.
