Railway tunnel large-section steel bar hanging and distributing integrated trolley

Abstract

The invention discloses a railway tunnel large-section steel bar hanging and distributing integrated trolley. The integrated trolley comprises a portal frame, and a working platform is fixed to the peripheral side of the portal frame; a traveling system is mounted at the bottom of the portal frame; a steel bar laying supporting system is fixed to the top of the portal frame; the integrated trolley further comprises an automatic waterproof plate laying traction system, and the automatic waterproof plate laying traction system comprises an arc-shaped rail fixed to the outer periphery side of the portal frame, a laying assembly slidably connected with the arc-shaped rail, and a rotary telescopic arm installed on the portal frame and used for pulling the laying assembly to slide along the arc-shaped rail, and the other end of the rotary telescopic arm is connected with a driving device for driving the rotary telescopic arm to rotate. According to the railway tunnel large-section steel bar hanging and distributing integrated trolley, by means of the automatic waterproof plate laying traction system, waterproof plate laying operation can be completed only by 3 persons-4 persons, and the waterproof plate construction efficiency is remarkably improved; the waterproof plate is laid smoothly without wrinkles, the quality is guaranteed, and the later tunnel defect renovation cost is reduced; and in addition, through the steel bar laying supporting system, steel bar spacing can be effectively controlled, and the construction quality is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a trolley integrated with large cross-section reinforcement hanging cloth for railway tunnels. Background technique [0002] With the development of railway construction, there are more and more tunnels, and waterproof membrane construction and reinforcement work are the key links in tunnel construction. At present, domestic tunnel construction mostly uses manual installation with simple benches, and the degree of mechanization is low. The simple platform has the following defects and deficiencies: the platform is welded by section steel, which is troublesome to assemble, cannot be reused, and has a large waste of materials; there is no hoisting system, the coils need to be manually moved, and the work efficiency is low; the number of construction operations is large, and the labor intensity of the workers is high ; It is not convenient for const...

Problems solved by technology

[0002] With the development of railway construction, there are more and more tunnels, and waterproof membrane construction and reinforcement work are the key links in tunnel construction. At present, domestic tunnel construction mostly uses manual installation with simple benches, and the degree of mechanization is low.

The simple platform has the following defects and deficiencies: the platform is welded by section steel, which is troublesome to assemble, cannot be reused, and has a large waste of materials; there is no hoisting system, the coils need to be manually moved, and the work efficiency is low; the number of construction operations is large, and the labor intensity of the workers is high ; It is not convenient for construction personnel to adjust the height of the side plates on both sides of the platform according to the actual situation; there are manual construction deviations, and the construction quality is difficult to guarantee; there is no running system, and the platform is inconvenient to move. long preparation time
