Embodiment 1

[0023] Embodiment 1: a kind of equipment for removing the inner track of the shield tunnel, see Figure 1-5 , can run on the track 11 in the shield tunnel 1, including rail transport vehicle 2, fixed frame 3, linear motion mechanism 4 and suspension mechanism 5. The fixed frame 3 is fixed on the rail transport vehicle 2, and the fixed frame 3 is extended to the outside of the tail of the rail transport vehicle 2, so that when removing the inner track of the shield tunnel, the required track for the rail transport vehicle 2 to enter and exit can be reserved first , and dismantle the track behind the access line of the rail transport vehicle 2, and gradually dismantle the track in the shield tunnel as the dismantling work progresses. The suspension mechanism 5 is installed on the movable block of the linear motion mechanism 4, and the base of the linear motion mechanism 4 is installed on the fixed mount 3, so that the linear motion mechanism 4 can drive the suspension mechanism ...

Abstract

The invention provides equipment for removing tracks in a shield tunnel so as to solve the technical problem of low steel track loading and transporting efficiency during the operation of removing thetracks in the shield tunnel. The equipment can run on the tracks in the shield tunnel and comprises a track transporter, a fixed rack, a linear movement mechanism and a lifting mechanism, wherein thefixed rack is fixed to the track transporter, and the fixed rack extends to the outer side of the tail of the track transporter; and the lifting mechanism is mounted on a movable block of the linearmovement mechanism, a base of the linear movement mechanism is mounted on the fixed rack, and the linear movement mechanism can drive the lifting mechanism to move above the lifting center of a to-be-loaded steel track behind the track transporter and above a loading center of the track transporter. The equipment is suitable for the lifting and transporting operation of the steel tracks in the shield tunnel.

Description

technical field [0001] The invention relates to the technical field of hoisting and transportation equipment, in particular to a device for removing rails in a shield tunnel. Background technique [0002] During the construction stage of the shield tunnel, it is necessary to lay tracks and cables in the tunnel to ensure the progress of construction operations and muck removal operations. However, after the construction of the tunnel project is completed, it is necessary to remove the tracks and cables set up during the construction process in time to facilitate the construction of subsequent transportation facilities. [0003] Restricted by the size of the section of the shield tunnel, currently the segment transport vehicle used during the shield tunneling construction is generally used to transport the dismantled rails, cables and other materials. Generally, the height difference between the cargo loading surface of the segment transport vehicle and the top surface of the...
