Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Such as Figure 1 to Figure 5 As shown, the extended multi-platform railway tunnel operation trolley includes a rail flat car 1, a door frame device, a side fixed working platform 3, a scissor lifting mechanism, and a top fixed lifting platform 4. The door frame device is composed of a door frame column 2. The crossbeam 20 and the oblique support 13 are connected to form, and the gantry column 2 is fixed on the rail flat car 1 by bolts; the left and right sides of the gantry device are symmetrically provided with four side fixed working platforms 3 with different heights. The side fixed working platform 3 and the door frame device are connected by fixed welding; the side fixed working platform 3 is connected with a side turning expansion platform 11 that can be turned 180° through the movable hinge 6 provided, and the side turning expansion platf...

Abstract

Provided is an extended type multi-platform railway tunnel operation trolley. According to the extended type multi-platform railway tunnel operation trolley, an existing rail flat car is used as a carrier; when the trolley is in a transportation state, all platforms are retracted and do not exceed the railway transportation boundary; when the trolley arrives at a work position, the operation platforms at all levels can be unfolded rapidly, all portions of a tunnel section can be completely covered with multiple working surfaces, and the multi-level expanded platforms can be adapted to various tunnel sections. The reasonable rack structure is achieved so that various types of mechanical equipment and materials can be placed, more synchronous operation platforms can be provided, and operation efficiency is improved; the multi-level expanded platforms can achieve operation close to the wall of a tunnel and can achieve operation on arch portions particularly, operation difficulty can be lowered greatly, work efficiency and construction safety can be improved greatly, labor intensity is reduced, cost is saved, and efficient construction for overcoming railway tunnel defects is completed.

Description

technical field [0001] The invention relates to a railway tunnel construction machine, in particular to an expanded multi-platform railway tunnel operation trolley. Background technique [0002] At present, the existing trolleys for disease control of railway tunnels mostly adopt the method of scaffolding lapping. According to the outline size of a specific tunnel, scaffolding is used to splice the platform into a work platform in advance, and rotatable side plates are set on both sides of the platform. Open the side panel and fix it on the scaffold. The work trolley formed by the overlapping of scaffolding has limited expansion functions, and the platform is far away from the tunnel boundary, especially the arch ring, so it is extremely inconvenient to work, especially for trenching and painting that need to be worked close to the tunnel lining. Waterproof materials and other processes. At the same time, this type of work trolley has fewer working surfaces, light weight, ...
