Embodiment Construction
[0034] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0035] The following description only uses the fixing device of the present invention to fix the foot plate on the crane frame as an example to illustrate the application of the fixing device of the present invention, but the application of the fixing device of the present invention is not limited thereto, but can be applied to any needs When fixing the first part to the second part.
[0036] Such as figure 2 As shown, two fixing devices 60 are fixedly arranged on the crane frame 10, and two fixing holes are provided on the foot plate 20 corresponding to the fixing devices 60, and the fixing holes are passed through the fixing devices 60, and to the vehicle frame 10. Push the foot plate 20 i...

The invention provides a fixing device and engineering machinery with the same. The fixing device comprises a support part, a locking part and a first elastic part. The support part comprises a first mounting seat, a second mounting seat and a limiting blocking part. The locking part comprises a connecting end, a locking end arranged opposite to the connecting end, and a control section positioned between the connecting end and the locking end, wherein the connecting end is connected to the first mounting seat in a rotating way; the locking end is positioned at a locking position or an unlocking position along with the variation of a rotating angle of the locking part; and the control section comprises a driving face and a resetting face, which are arranged opposite to each other. The limiting blocking part is positioned on one side of the driving face. When the locking end is at the locking position, the driving face is pressed against the limiting blocking part, and when the locking end is at the unlocking position, the driving face is away from the limiting blocking part. The first elastic part is arranged on the second mounting seat, and is pressed against the resetting face of the locking part. According to the fixing device, a part to be fixed such as a support leg plate can be rapidly arranged and disassembled; and the fixing device is convenient to operate, and working efficiency is improved.
Description
technical field [0001] The invention relates to the field of engineering machinery, and more specifically, to a fixing device and an engineering machinery with the same. Background technique [0002] Such as figure 1 It is shown that in the prior art, the fixing between the foot plate 20' and the vehicle frame 10' of the crane is mainly through passing the fixing column 40' on the vehicle frame 10' into the corresponding fixing hole on the foot plate 20', and then Use the spring pin 50' to penetrate into the positioning hole on the fixing post 40', and at the same time cooperate with the limiting plate 30' under the supporting foot to realize auxiliary fixing. [0003] In the prior art, the fixing method of the above crane and the foot plate has the following deficiencies: [0004] 1, foot plate 20 ' all will pull out spring pin 50 ' when installing and taking off, and work efficiency is lower. [0005] 2. The spring pin 50' is small and easily lost, and there is a potent...
