Hydraulic cylinder support arm for track laying machine

Abstract

The invention discloses a hydraulic cylinder support arm for a track laying machine. The hydraulic cylinder support includes a chassis, a lower support arm is arranged at the top of the chassis; the lower support arm comprises a first lower support arm, a second lower support arm, a third lower support arm and a fourth lower support arm; the upper ends of the first lower support arm, the second lower support arm, the third lower support arm and the fourth lower support arm are sleeved with upper support arms; height adjusting hydraulic cylinders are arranged in the first lower support arm, thesecond lower support arm, the third lower support arm and the fourth lower support arm; an angle adjusting hydraulic cylinder is arranged between the first lower support arm and the second lower support arm; the fixed end of the angle adjusting hydraulic cylinder is hinged to the bottom end of the second lower supporting arm. The free end of the angle adjusting hydraulic cylinder is hinged to theupper end of the first lower supporting arm, an angle adjusting hydraulic cylinder is also arranged between the third lower supporting arm and the fourth lower supporting arm, the fixed end of the angle adjusting hydraulic cylinder is hinged to the lower end of the third lower supporting arm, and the free end of the angle adjusting hydraulic cylinder is hinged to the upper end of the fourth lowersupporting arm. The hydraulic cylinder support arm is simple in structure and can safely support the rail layer.

Description

technical field [0001] The invention belongs to the technical design field of hoisting machinery used in tunnels, and in particular relates to a hydraulic cylinder support arm for a track laying machine. Background technique [0002] In the process of tunnel traffic construction, the track pavement project is in the middle of the civil engineering and equipment installation projects in terms of construction schedule. It is the immediate process of civil engineering and the immediate process of other equipment installation projects. It has a huge impact on the progress of subsequent equipment installation and commissioning. In the various processes of tunnel track installation engineering construction, the laying of inner rails and concrete pouring in the tunnel are the key processes, and it is also the most important and difficult to control part of the production schedule. As the most critical equipment in this link, the technology of tunnel track laying machine Performanc...

AI Technical Summary

Problems solved by technology

The space in the tunnel is small, and there are many risk factors, inconvenient operation, long working time and other unfavorable factors in changing the span and structure of the tunnel track-laying machine in the tunnel. Once the tunnel track-laying machine in the tunnel is stopped, the entire track paving process will be stagnant , causing idle work

In the existing technology center, the tunnel track-laying machine needs to be hoisted by the gantry crane to change the span, or the tunnel track-laying machine is disassembled when the span is changed, so the efficiency is very low; In the transition situation, the door crane must be disassembled and reassembled every time the transition is made, which affects the progress of the project
