AI Technical Summary

Technical Problem

The existing curb installation crane is not retractable or unmovable, and cannot adapt to changes in curbs of different widths and construction progress, resulting in low construction efficiency and high cost.

Method used

A curb-mounted crane is designed, and its cross frame can be adjusted in width, so that different widths can be adapted through the combination of the first telescopic frame, the connecting rod and the second telescopic frame; at the same time, a movable universal wheel is arranged under the support frame to realize the mobility of the crane frame.

Benefits of technology

The lifting and installation of curbs of different widths is realized, which improves construction efficiency and applicability, while reducing construction costs.

Abstract

The utility model discloses a kerb installation hoist frame which comprises a pair of supporting frames, a pair of supporting frames and a pair of supporting frames. Each supporting frame is of an A-shaped structure and is supported on one side of the hoist frame. The two ends of the transverse frame are connected with the pair of supporting frames; the transverse frame comprises a first telescopic frame, a connecting rod and a second telescopic frame, one end of the first telescopic frame is connected with one supporting frame, one end of the second telescopic frame is connected with the other supporting frame, and the two ends of the connecting rod are connected with the other end of the first telescopic frame and the other end of the second telescopic frame respectively; wherein the first telescopic frame comprises a first rod piece, a second rod piece and a third rod piece, a pair of first racks are arranged above and below the first rod piece, a pair of gears are arranged above and below the second rod piece, a pair of second racks are arranged above and below the third rod piece, and the two ends of the pair of gears are matched with the pair of first racks and the pair of second racks respectively. The width of the curb installation hoist frame is adjustable and controllable, and curbs can be hoisted and installed in the construction process of curbs with different widths.
