Description

Technical Field

[0001] The utility model relates to the technical field of excavator accessories processing, in particular to a novel auxiliary supporting device of an excavator with low manufacturing cost and strong stability. Background Art

[0002] At present, the new auxiliary support device of the excavator has a relatively simple structure and a high manufacturing cost. During the lifting and retracting process, the outriggers occupy more space and have a smaller contact surface with the ground, resulting in poor support and impact resistance. In addition, the existing auxiliary support device is prone to deformation.

[0003] In the prior art, the auxiliary support device of the excavator is mainly composed of a support leg and a support arm. In actual use, due to the relatively simple structural design of the support leg and the small contact area with the ground, the support stability is insufficient. At the same time, due to the limited adjustment range of the length and angle of the support arm, the excavator cannot provide sufficient support and stability in different terrains and working environments.

[0004] In addition, the existing auxiliary support device has a high manufacturing cost, mainly because of its complex structure and complicated manufacturing process. Therefore, how to provide an auxiliary support device for an excavator with a simple structure, low manufacturing cost and good supporting performance has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The purpose of the utility model is to provide a new auxiliary support device for an excavator with low cost and strong stability in view of the above problems.

[0006] In order to achieve the above-mentioned purpose, the utility model discloses a new auxiliary support device for an excavator, including a frame and a bracket welded on the frame, wherein telescopic cylinders are hingedly connected in the body at the left and right ends of the bracket, and its structural feature is that articulated frames are arranged on the left and right sides of the bracket, and a bracket matching the telescopic cylinder is arranged on the articulated frame, and the outer end of the bracket is hingedly connected with a support leg that automatically opens and closes.

[0007] After adopting the above structure, the bracket and the automatically opening and closing legs are welded and installed on the bracket. The legs can open and close and swing synchronously according to their own center of gravity during the opening and closing process of the bracket, which not only increases the contact area with the ground, but also improves the support stability and further enhances the impact resistance and deformation resistance of the legs.

[0008] Preferably, the leg includes a pad and two reinforcing ribs welded to the inner end surface of the pad, the pad is a rectangular plate and the two ends of the rectangular plate along the lifting direction are bent toward the inner end surface and are symmetrical to each other along the central axis of the length direction of the plate body, the two reinforcing ribs are arranged at intervals along the width direction of the pad and vertically welded to the inner end surface of the pad, and the two reinforcing ribs are provided with corresponding pin hinge holes and the pin hinge holes are close to the outer end of the pad. By placing the pin hinge holes close to the outer end of the pad, the pad can be easily lifted during the lifting process of the bracket, and the inner end of the pad is always lower than the outer end, thereby realizing the automatic opening and closing of the pad through a simple structure.

[0009] Preferably, both reinforcing ribs are triangular plates and the two corners of the lower bottom edge are in contact with the plate with the inner end face bent, the upper corner of the reinforcing rib is located on one side of the vertical plane where the center axis of the pad length direction is located and close to the outer end of the pad, and the pin hinge hole is arranged at the upper corner of the reinforcing rib. By arranging the pin hinge hole at the upper corner of the reinforcing rib, the inner end of the pad can be kept lower than the outer end during the lifting and lowering of the bracket.

[0010] Preferably, the articulated frame includes connecting plates respectively welded to the front and rear side walls of the bracket and extending out of the vertical plane where the welded end of the bracket is located, and the length of the lower plate body of the two connecting plates is greater than the length of the upper plate body.

[0011] Preferably, the bracket includes two baffles spaced apart in the front and rear directions and a plurality of reinforcing plates connecting the two baffles are arranged between the two baffles, a connecting tube for installing a pin shaft is arranged at the outer end of the bracket along the front and rear directions, a first hinge hole hinged to the hinge frame is arranged on the inner ends of the two baffles, and a second hinge hole hinged to the telescopic cylinder is arranged at the upper part of the plate body between the first hinge hole and the connecting tube.

[0012] Preferably, the upper end surface of the bracket is provided with a positioning plate perpendicular to the upper end surface and a positioning hole is provided on the positioning plate, and a plug-in base for plugging into the positioning plate is provided on the bracket welded above the two hinged frames, and the plug-in base includes two baffles arranged at intervals and through holes aligned with the central axis of the positioning hole are provided on the two baffles. By matching the plug-in base with the positioning plate, the bracket can be further fixed by a latch when it is folded, so as to prevent the bracket from shaking when the vehicle is working.

[0013] To sum up, the beneficial effects of the utility model are: the utility model has a simple structure, a stable structure and is not easy to deform. The bracket and the automatically opening and closing legs are welded and installed on the bracket, and the legs can be synchronously opened and closed and swung according to their own center of gravity during the opening and closing process of the bracket, which not only increases the contact area with the ground, but also improves the support stability, and can further enhance the impact resistance and deformation resistance of the legs.
