Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Should be clear, the utility model use orientation with the using state of coal-winning machine for benchmark.Particularly, in the orientation shown in Fig. 1, the orientation shown in the left side for orientation shown in " left side ", the right be " right side ".
It is the structural representation of the coal mining machine supporting device of the utility model one embodiment shown in Fig. 1, this coal mining machine supporting device is supported on seat earth, in the process of mining, along with rough seat earth advances (left and right directions shown in Fig. 1).Be the schematic diagram of coal mining machine supporting device of the present utility model in installment state shown in Fig. 2, its relative position relation in coal-winning machine can be found out.
Previous embodiment comprises the support portion be made up of skid 3, and skid 3 is positioned at left and right directions.The quantity of support portion is two, and each support portion also comprises support cylinder 4 and connecting rod 5; Support cylinder 4 is positioned at above-below direction, and its two ends are connected on frame 6 and skid 3; Connecting rod 5 is positioned at left and right directions, and its two ends are connected on frame 6 and skid 3.
Should be clear, in the embodiment shown in fig. 1, the quantity of support portion is two, is divided into left support portion 1 and right support portion 2.The quantity of this support portion can also be three even more, and then be applicable to the longer coal-winning machine of fuselage length.
Aforementioned frame 6 is as the installation foundation of support cylinder 4, connecting rod 5, and it can be formed with the other parts one of coal-winning machine or split.Manufacture and space layout for the ease of installing, preferred aforementioned left support portion 1 connects the left tractive unit of coal-winning machine, and right support portion 2 connects the right tractive unit of coal-winning machine.The structure of left tractive unit and right tractive unit can with reference to technology that is existing and that improve.
