Embodiment Construction
[0032] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0033] Below in conjunction with accompanying drawing, each preferred embodiment of the present invention is described further:
[0034] Figure 1 to Figure 4 It shows a schematic structural view of the cover support device provided by the embodiment of the present invention. The cover support device is arranged between the frame of the construction machine and the cover. Taking a road roller as an example, the cover support device is arranged on the vehicle of the road roller. Between the frame and the cover, specifically, it includes:
[0035] A support rod assembly, the support rod assembly includes a main support rod 1 and a secondary support rod 2, the main support rod 1 is provided with a first hinged end 101, a second hinged end 102 and a third hinged portion 103, the first hinged end 101 and The se...

The invention discloses an engineering machine and a covering piece support device thereof. The covering piece support device comprises a support rod assembly and a driving part, wherein the support rod assembly comprises a main support rod and at least one auxiliary support rod, and the main support rod is provided with a first hinging end and a second hinging end; the first hinging end of the main support rod is hinged with a frame, one end of the auxiliary support rod is hinged with the second hinging end of the main support rod, and the other end of the auxiliary support rod is hinged with a covering piece; and the driving part is used for driving the main support rod to rotate through rolling the first hinging end, and the other end of the auxiliary support rod can provide support action for the covering piece. The covering piece support device provided by the invention is composed of multiple constructional elements through hinging, and therefore, the covering piece generates vibration, and the vibration transfers each constructional element so as to suffer smaller vibration; and compared with an air spring, the main and auxiliary support rods both have higher shock resistance, so that, the covering piece support device provided by the invention is not easy to damage because of the vibration of the covering piece.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to an engineering machinery and a cover supporting device thereof. Background technique [0002] The covering parts of construction machinery, such as the engine cover, have a protective effect on the internal structure of the machine. When the construction machinery is working, close the cover to prevent foreign impurities from entering the machine and affect the normal operation of the machine; when the construction machinery needs maintenance, open the cover so that the operator can check the internal components of the machine. [0003] After the cover is opened, the cover needs to be supported by the support device to prevent it from falling and hurting. The technical vehicle frame is connected, and the other end is connected with the cover. The disadvantage of this type is that the cover part is prone to vibration during the operation of the construction machinery, and the...
