Problems solved by technology
The driveway slabs on both sides are prefabricated in advance, and then transported to the site manually or mechanically in the later stage. The traditional scaffolding method is mostly used to install the driveway slabs. The construction space is limited, the construction progress is slow, and the construction period of the internal structure of the shield tunnel is restricted.
It affects the later work. In addition, the prefabricated side stones in the later stage are of high quality, and manual transportation and installation are time-consuming and labor-intensive, which greatly delays the construction period and hinders the orderly progress of the project

Embodiment Construction
[0013] In order to illustrate the technical solution of the present invention more clearly, the accompanying drawings that need to be used in the following will be briefly introduced. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, In other words, other drawings can also be obtained from these drawings on the premise of not paying creative work.
[0014] Such as figure 1 , As shown in 2, the mobile hoisting device for installing the internal structure of the tunnel of the present invention includes: a main structure, a crawler-type walking mechanism, a chain hoist device, and a power unit. The power unit is connected with the crawler type traveling mechanism. The crawler-type traveling mechanism is composed of guide wheels 3, left and right track frames 2, support rollers 4, track assemblies 5, reducer assemblies and drive wheels 6, and the guide wheels 3, reducer ass...

The invention relates to a movable lifting device for installing a tunnel internal structure. The movable lifting device comprises a body structure, a crawler type walking mechanism, a chain hoist device and a power device. The crawler type walking mechanism driven by the power device is installed on the lower face of the body structure. A front beam of the body structure is connected with the chain hoist device through a chain hoist track beam. The chain hoist device hoists prefabricated roadway planks or curbstone through a lifting hoist and moves through the crawler type walking mechanism under the drive of the power device to lay the prefabricated roadway planks or place curbstone. Through the movable lifting device, no scaffold is erected, and the input of manpower and materials is greatly reduced; and the construction efficiency of the shield tunnel internal structure is improved, the traffic pressure in a tunnel during construction is relieved, the transportation of prefabricated materials is ensured, and the synchronous construction of the internal structure and other structures in the tunnel is realized.
Description
technical field [0001] The invention relates to a shield tunnel technology, in particular to a mobile hoisting device used for installing the inner structure of the tunnel. Background technique [0002] With the rapid development of technology in the construction industry, a large number of large-scale shield tunnels in my country have been put into construction. When large-scale shield machines penetrate the entire tunnel, the internal structure of the tunnel needs to be carried out in an orderly manner. The "pavement" in the internal structure is mostly prefabricated openings and Cast-in-place corbels, where driveway slabs rest. Among them, the prefabricated openings are installed synchronously with the shield tunneling construction, the installation process is relatively mature, and the construction efficiency is high. The driveway slabs on both sides are prefabricated in advance, and then transported to the site manually and mechanically. The traditional scaffolding meth...
