Problems solved by technology

However, in this way, laying additional construction tracks in the shield tunnel not only increases the construction time and cost, but also invades the construction space, which is especially inconvenient for construction workers to walk in the shield tunnel, and it cannot meet the full-section maintenance work

Embodiment

[0017] Example: such as figure 1 with figure 2 As shown, the main body of the shield tunnel trackless walking full-section maintenance platform frame in this embodiment is a portal frame body 1. The portal frame body 1 serves as the main body supporting member of the platform frame, which has a portal space 10 for The trams pass through the portal frame 1 freely, without affecting the normal construction of the shield.

[0018] A main platform 2 is provided on the upper part of the portal frame body 1, and the main platform 2 is mainly used by construction personnel to repair the top segment of the shield tunnel 6. An extension platform 3 is respectively provided on both sides of the main platform 2, and the extension platform 3 is mainly used by construction personnel to repair the segments on both sides of the shield tunnel 6. The main platform 2 and the extension platform 3 solve the limitation of the working height and width of the shield tunnel 6, so as to realize the full-...

Abstract

The invention relates to the technical field of shield tunneling equipment, in particular to a trackless traveling type full-section maintenance platform frame for a shield tunnel. The trackless traveling type full-section maintenance platform frame is characterized by comprising a portal frame body, a main platform is arranged at the top of the portal frame body, and extension platforms are arranged on two sides of the main platform respectively; wheel sets are arranged at the bottom of the portal frame body, the portal frame body is supported in the shield tunnel through the wheel sets and can be pushed to move on a pipe section surface of the shield tunnel, and vertical fixation of the portal frame body in the shield tunnel is realized by braking of the wheel sets; transverse supporting rods are arranged on outer sides of the extension platforms, and horizontal limiting of the portal frame body in the shield tunnel is realized by the transverse supporting rods abutted against the pipe section surface of the shield tunnel. The trackless traveling type full-section maintenance platform frame has advantages of simple structure, low dead weight, convenience in demounting, high stability, high safety and suitableness for popularization.

Description

Technical field [0001] The invention relates to the technical field of shield tunnel construction equipment, in particular to a full-section maintenance platform frame for trackless walking of shield tunnels. Background technique [0002] During the maintenance of shield tunnels, a construction trolley that can travel in the shield tunnel is often used to assist the construction to solve the restrictions on the height and breadth of the operation and to ensure the personal safety of the constructors. The cross-sectional shapes of shield tunnels are usually round and elliptical. In order to enable the construction vehicle to run stably on such curved segments, in the prior art, tracks along the direction of the tunnel route are often laid in the shield tunnel to make the construction The wheels of the trolley are stuck in the track, so that the construction trolley can move stably along the track. However, as a result, laying additional construction tracks in the shield tunnel no...
