Embodiment Construction
[0022] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] Such as figure 1 The aerial work platform shown includes a lifting device 1, a lifting platform 7, a fence 2, a fuselage base 3, a lifting device mounting frame 6, front wheels 5 and rear wheels 9. Lifting device 1 is fixed on the lifting device installation frame 6, and lifting platform 7 is fixed on the lifting device 1, and front wheel 5 and trailing wheel 9 are fixed on the fuselage base 3. In addition, the above-mentioned aerial work platform also includes an anti-pothole tilting device. The anti-pothole tilting device includes two protective plates 4 and a push rod device 8. The two protective plates 4 are respectively hinged and arranged on the fuselage of the aerial work platform. Below the two side plates 10 of the base 3, and vertically arranged on the side plates 10, the upper end of the ejector device 8 can be...

The invention relates to a lifting machine with a safety device, in particular to a lifting machine with an anti-pit inclined device. The lifting machine with the anti-pit inclined device includes an anti-pit inclined device; the anti-pit inclined device includes fenders which are respectively hinged below the two side plates of the machine chassis and a push rod device with the upper end which can rejects a lifting platform; the two fenders are vertically arranged and respectively connected with the push rod device by a transmission device; the transmission device is a steel wire rope; the lower part of the push rod device rejects to the steel wire rope; both sides of the push rod device are respectively provided with a lifting tackle; both sides of each lifting tackle are respectively provided with a positioning pulley; the steel wire rope goes through the lifting tackles and the positioning pulleys; both ends of the steel wire rope are respectively fixedly connected with the fenders; when the push rod device presses the steel wire rope, the steel wire rope pulls and folds the fenders. The invention is characterized by simple structure and convenient implementation, is applicable to all lifting machines, in particular to high-altitude operation platforms.
Description
technical field [0001] The invention relates to a lifting machine with a safety device, in particular to a lifting machine with an anti-pothole tilting device. Background technique [0002] The existing aerial work platform includes a fuselage, a walking device, a lifting device and a working platform. The working platform is arranged above the lifting device; Drum type lifting device; traveling device can be wheel type traveling device. The distance between the lower part of the body of the existing aerial work platform and the ground is designed to be relatively large, because when the aerial work platform is walking, there may be some prominent obstacles on the ground, such as small mounds or stones, etc., and the distance between the lower part and the ground is relatively large. The large distance can avoid the obstruction of the walking of the aerial work platform. [0003] But above-mentioned improvement has just brought unsafe problem factor in use. Because, durin...
