Abstract

The invention relates to a trackless gantry crane, which is characterized in that: a first folding support seat and a second folding support seat are connected to the left and the right of a rear buttress, a third folding support seat and a fourth folding support seat are connected to the front and the back of a front buttress, and a rotating base is in connection with a telescopic suspension arm. The beneficial effects of the invention are that: the arrangement of the four folding support seats makes the chassis more stable, the design of the rotating base and the telescopic suspension arm endows a larger working area, and the working efficiency is improved.

Description

A kind of railless gantry crane

?

Technical fieldThe present invention relates to the crane field, relate to concretely a kind of railless gantry crane.

Background technologyTrackless portal jib crane mainly is applicable to the needs of common science of bridge building, because of its constraint that de-orbits, realizes moving flexibly, is subject to user's welcome; The scope of operation is little in traditional trackless portal jib crane working process, to slightly remote material demand motive running gear, and inefficiency, the bottom is built on the sand during work.

Summary of the inventionDefective in view of prior art exists the purpose of this invention is to provide a kind of railless gantry crane that a kind of scope of operation is large, efficient is high, the chassis is firm.

For achieving the above object, the technology used in the present invention solution mainly is comprised of the first folding bearing, the second folding bearing, the 3rd folding bearing, the folded bearing of four fold, rotating base, scalable arm, rear buttress, front buttress.

A kind of railless gantry crane is characterized in that: be connected about the first folding bearing, the second folding bearing and rear buttress, the 3rd folding bearing, the folded bearing of four fold are connected with front buttress front and back, and rotating base is connected with scalable arm.

The invention has the beneficial effects as follows: four folding bearings are set, make the chassis more firm, rotating base and the design of scalable arm make working face of the present invention larger, have improved work efficiency.

Description of drawings

Fig. 1 is structure diagram of the present invention.

The specific embodiment

Fig. 1 Reference numeral is as follows: the first folding bearing 1, the second folding bearing 2, the 3rd folding bearing 3, the folded bearing 4 of four fold, rotating base 5, scalable arm 6, rear buttress 7, front buttress 8.

In the structure diagram of a kind of railless gantry crane shown in Figure 1, its keystone configuration comprises: the first folding bearing 1, the second folding bearing 2 are connected with rear buttress about 7, the 3rd folding bearing 3, the folded bearing 4 of four fold are connected with front buttress 8 front and back, and rotating base 5 is connected with scalable arm 6.

Claims

1. a railless gantry crane is characterized in that: be comprised of the first folding bearing, the second folding bearing, the 3rd folding bearing, the folded bearing of four fold, rotating base, scalable arm, rear buttress, front buttress; Be connected about the first folding bearing, the second folding bearing and rear buttress, the 3rd folding bearing, the folded bearing of four fold are connected with front buttress front and back, and rotating base is connected with scalable arm.
