Double-position cantilever vehicle

Abstract

The invention discloses a double-position cantilever vehicle, which comprises a vehicle body, wherein walking wheel mechanisms are arranged on both sides of the vehicle body respectively; an elevating mechanism for controlling a first steel pipe is arranged on the front end part of the vehicle body; a cantilever device for controlling a second steel pipe is arranged on the back end part of the vehicle body; a first hydraulic cylinder is arranged on the vehicle body; guide posts are arranged on both sides of the first hydraulic cylinder respectively; copper sleeves matched with the guide posts are arranged on the outer peripheral faces of the guide posts respectively; the copper sleeves are fixed on a bracket; a support frame is arranged on the top of a piston rod of the first hydraulic cylinder; the two ends of the support frame are pressed against the guide posts; the support frame is provided with a first V-shaped block for mounting the first steel pipe; a support post is arranged on the middle part of the vehicle body; a cantilever frame is arranged on the top of the support post through a revolving shaft; the cantilever frame extends out of the outer end of the vehicle body; a second hydraulic cylinder is arranged at the back end of the vehicle body; a piston rod of the second hydraulic cylinder is pressed against the middle part of the cantilever frame; a second V-shaped block for mounting a second steel pipe is arranged at the tail part of the cantilever frame. The double-position cantilever vehicle has high working efficiency.

Description

technical field [0001] The invention relates to the technical field of welded pipe processing equipment, in particular to a double-station cantilever car used in a straight seam metal welded pipe production line. Background technique [0002] In the industrial production process, large workpieces such as pipes need to be transported to the position of the steel pipe due to the processing and manufacturing needs of each station in the production line during the operation of the assembly line. Such as the processing of the expansion machine station in the steel pipe production line and the export station of the finished steel pipe. The diameter expansion machine belongs to the straight seam metal welded pipe shaping equipment and is one of the main equipments in the whole production line. It uses a cone expansion head. The internal expansion of the steel pipe can eliminate the forming pressure generated during the forming process of the steel pipe and the welding stress genera...

AI Technical Summary

Problems solved by technology

[0004] (1) Manual operation is used for driving and lifting, which has low work efficiency and high labor intensity. Due to the large volume and quality of the pipe material, there are great safety hazards during transportation;

[0005] (2) The single-station car body is used for transportation. During the working process, the car body needs to be reciprocated to complete the next process, which is not only inefficient, but also consumes a lot of energy
