Embodiment Construction

[0015] Attached below Figure 1-2 The present invention will be further described in detail, but not as a limitation to the present invention.

[0016] refer to figure 1 , figure 2 , a device for sleeper shock absorption, derailment, and segment damage prevention of a shield underground transportation system according to the present invention includes a shield segment 60, a rail track 10 is arranged on the upper side of the shield segment 60, and a transport vehicle is arranged on the track 10 , The inner upper side of the shield segment 60 is also provided with a profiled steel sleeper 20 , and the fastening device 50 is used to connect the sleeper 20 to the rail 10 . In this embodiment, the fastening device 50 is a pressing plate type bolt fastening device. Both ends of the sleeper 20 are provided with fixed ends, and the lower surface of the fixed end in contact with the shield segment 60 is arc-shaped, and the radius of the arc is the same as the inner arc radius of th...

Abstract

The invention relates to a sleeper damping, derailment-preventing and segment-damage-preventing device for a shield underground transportation system, and belongs to the technical field of shield equipment. Profile steel is arranged to serve as a sleeper, steel rails matched with a transport vehicle serves as rails, and the steel rails and the sleeper are connected in a pressing plate mode and fastened through bolts. According to the invention, the contact surface of the sleepers and a shield segment is designed into an arc with the same radius as the inner side structure of the segment, the profile steel serving as the sleeper is designed into a groove type, a rail determinator is cancelled, and damping rubber plates are additionally arranged among the sleeper, the shield segment and thesteel rails, the damping rubber plates and the sleeper are fixed through bolts, so that during shield construction, vibration and noise generated by the underground transportation system are effectively reduced and controlled, the segment is protected, the derailment phenomenon caused by the fact that wheels dynamically impact the steel rails to vibrate is reduced, the track mounting effect is improved, manpower, material resources and financial resources are saved, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to a shock absorbing, derailing, and segment damage preventing device for a sleeper in a shield tunneling underground transportation system, and belongs to the technical field of shield tunneling equipment. Background technique [0002] At present, in shield construction, the underground transportation system is mainly composed of traction locomotives, dregs pallets, segment pallets, muck buckets, mortar buckets, and corresponding sleepers and tracks. The advantage of the rail transportation method is that it is highly adaptable, and the industrial technology and products adopted by the system itself are extremely mature and reliable. The transportation system constructed by the shield tunneling method in China all adopts the rail type. The disadvantage is that during the transportation of muck, materials, etc., the dynamic interaction between the vehicle and the track generates vibration, which reacts on the rails and sleepers th...
