Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing.

[0039] figure 1 A lining trolley 500 according to the invention is shown. Such as figure 1 As shown, the lining trolley 500 includes a portal system 300 , a lower pouring system 100 and an upper pouring system 600 .

[0040] Specifically, such as figure 2 As shown, the mast system 300 includes two longitudinal beams 301 , a front mast assembly 302 , a rear mast assembly 303 and a connecting beam 304 . Wherein, the longitudinal beams 301 are arranged at intervals relative to each other in the transverse direction. The front mast assembly 302 is disposed on the longitudinal beam 301 . At the same time, the rear door frame assembly 303 is arranged on the longitudinal beam 301 , and is spaced apart from the front door frame assembly 302 longitudinally. The connecting beam 304 itself is cylindrical, and it is arranged between the front door frame assembly 302 and the rear...

Abstract

The invention provides a portal frame system for a lining trolley and the lining trolley. The portal frame system comprises two longitudinal beams oppositely arranged in a spaced way, a front portal frame assembly arranged on the two longitudinal beams, a back portal frame assembly arranged on the two longitudinal beams and arranged opposite to the front portal frame assembly in a spaced way and longitudinally extending cylindrical connecting beams arranged between the front portal frame assembly and the back portal frame assembly, wherein the connecting beams are connected with the upper portion of the front portal frame assembly and the upper portion of the back portal frame assembly, and a slippage space is formed between the connecting beams. The portal frame system is simple in structure.

Description

technical field [0001] The invention relates to the technical field of tunnel construction tools, in particular to a portal frame system and a lining trolley for a lining trolley. Background technique [0002] With the rapid development of my country's social economy, the field of transportation infrastructure is also developing rapidly. In the construction of railway and highway traffic network, it is necessary to carry out secondary lining of concrete on the inner surface of the excavated tunnel. Concrete secondary lining is an important process and link in tunnel construction, and its construction level directly affects the quality, construction speed, construction cost and management of the tunnel during operation. [0003] At present, the tunnel lining trolley is used as the main equipment for the construction of the second lining of the tunnel, which effectively reduces the labor intensity and improves the operation efficiency of the second lining construction. Howev...
