Anti-collision device for shield machine trolley

Abstract

The invention provides an anti-collision device for a shield machine trolley. The anti-collision device comprises an anti-collision beam and a steel spring plate; the anti-collision beam is horizontally arranged in front of the trolley, the left side wall and the right side wall of the upper end of the anti-collision beam are correspondingly and fixedly connected with a left boundary beam and a right boundary beam of the trolley through fixed arms; the steel spring plate is arranged on the surface of the anti-collision beam in the face of a feeding movement direction of an electric flat car; areflective laser sensor is arranged in the middle part of the anti-collision beam; the reflective laser sensor irradiates to the feeding movement direction of the electric flat car, and the reflective laser sensor is connected with a distance warner. The anti-collision device for the shield machine trolley disclosed by the invention can give out an early warning when the electric flat car entersthe collision dangerous range, thereby prompting a worker to operate a brake device; and meanwhile, the collision strength is effectively reduced, the deformation on the equipment caused by the collision is reduced, the equipment normal work is realized, and the maintenance quantity is reduced.

Description

technical field [0001] The invention belongs to the field of tunnel shield engineering, in particular to an anti-collision device for a trolley of a shield machine. Background technique [0002] When the tunnel shield machine is working, the segments and various slurries used need to be transported into the shield by level vehicles. The guide rail used for the operation of the level car can only be laid behind the tail shield. As the shield machine continues to work, the guide rail is also continuously laid correspondingly, so the limit switch cannot be set to control the exact parking position of the level car. Parking using manual controls. If the manual control error causes the level car to fall off the track and rush into the shield, it will cause equipment damage and the danger of various materials tipping over. [0003] Under the existing technical conditions, in order to prevent the level car from rushing into the shield, only a stopper is welded to the side beam of...
